LIST OF THE PUBLICATIONS

OF THE

ZOOLOGICAL SOCIETY OF LONDON,

TuE scientific publications of the Zoological Society of London
‘are of two kinds—“ Proceedings,” published in an octavo
form, and “‘ Transactions,” in quarto.

According to the present arrangements, the “ Proceedings”
contain not only notices of all business transacted at the scien-
tific meetings, but also all the papers read at such meetings
and recommended to be published in the “ Proceedings” by
the Committee of Publication. A large number of coloured
plates and engravings are attached to each annual volume of
the “ Proceedings,” to illustrate the new or otherwise remark-
able species of animals described in them. Amongst such
illustrations, figures of the new or rare species acquired in a
living state for the Society’s Gardens are often given.

The “ Proceedings” for each year are issued in four parts,
on the first of the months of June, August, October, and
April, the part published in April completing the volume for
the preceding year.

The “ Transactions” contain such of the more important
communications made to the scientific meetings of the Society
as, on account of the nature of the plates required to illustrate
them, are better adapted for publication in the quarto form.
They are issued at irregular intervals.

Fellows and Corresponding Members, upon payment of
a Subscription of One Guinea before the day of the Anni-
versary Meeting in each year, are entitled to receive all the
Society’s Publications for the year. They are likewise
entitled to purchase the Publications of the Society at 25 per
cent. less than the price charged for them to the Public. A
further reduction of 25 per cent. is made upon purchases of
Publications issued prior to 1871, if they exceed the value of
five pounds.

The following is a complete list of the publications of
the Society already issued. They may be obtained at
the Society’s Office (8 Hanover Square, W.), at Messrs.
Longmans’, the Society’s publishers (Paternoster Row, E.C.),
or through any bookseller.

THE ZOOLOGICAL SOCIETY OF LONDON,

Tus Society was instituted in 1826, under the auspices of Sir
Homrnrey Davy, Bart., Sir Sramrorp Rarries, and other eminent
individuals, for the advancement of Zoology and Animal Physiology,
and for the introduction of new and curious subjects of the Animal
Kingdom, and was incorporated by Royal Charter in 1829.

During the period which has elapsed since the opening of the
Gardens in the Regent’s Park in 1828, a very large number of
species of Mammats, Brrps, and Reprizs has been obtained, detailed
lists of which will be found in the published Catalogues of the
Collection. To these were added, in 1852, collections of Fisuxs
and of the Lower Aquatic Anmats, both marine and freshwater,
and in 1881 a House for the breeding and exhibition of Insects and
other Articulata.

TERMS FOR THE ADMISSION OF FELLOWS. -
Frttows pay an Admission Fee of £5, and an annual Contri-
bution of £3, due on the Ist of January, and payable in advance,
or a Composition of £30 in lieu thereof; the whole payment,
including the Admission Fee, being £35.

Fexrows elected after the 30th of September are not liable for
the Subscriptions for the year in which they are elected.

PRIVILEGES OF FELLOWS.

Fettows have Personal Admission to the Gardens with Two
Companions daily, upon signing their names in the book at the
entrance gate.

Fetiows of the Society receive a Book of Saturday, and a Book of
Sunday Orders. These Orders admit two persons to the Gardens on
each Saturday and two on each Sunday in the year. But the
Saturday Orders are not available if the Frtiow uses his privilege
of personally introducing two companions on the same day.

Fettows, if they wish it, can exchange the Book of Saturday
Orders for Twenty Tickets, available for any day during the year of
issue. The Book of Sunday Orders can also be exchanged for a
similar packet of Twenty Tickets. These tickets will admit only
one person, whether child or adult.

3

Fettows also receive Twenty Free Tickets (Green), each valid
for the admission of one adult any day of the week including
Sunday. Children’s Tickets (Buff) can be had in lieu of Green
Tickets in the proportion of two Children’s Tickets to one Adult’s.
These Tickets, if not made use of in the year of issue, are available
for following years.

The Books of Orders and the Free Tickets are sent to all Fettows
who shall have given a General Order for their delivery, on the Ist
of January in every year, at any specified address. Forms for this
purpose are supplied on application.

The Wire of a Fettow can exercise all these privileges in his

absence.

Fettows have the privilege of receiving a complete set of the
Society’s Publications on payment of the additional Subscription of
One Guinea every year. This Subscription is due upon the Ist of
January and must be paid before the day of the Anniversary
Meeting, after which the privilege lapses. Fxrttows are likewise
entitled to purchase the Transactions and other Publications of ‘the
Society at 25 per cent. less than the price charged to the public.
A further reduction of 25 per cent. is also made upon all purchases
ef Publications issued prior to 1871, if above the value of Five
pounds.

Fettows also have the privilege of subscribing to the Annual
Volume of the Zoological Record for a sum of £1, payable on the
1st July in each year, but this privilege only holds good if the
subscription is paid before the 1st of December following.

Fettows may obtain, on the payment of One Guinea annually,
an Ivory Ticker, which will admit a named person of their imme-
diate family, resident in the same house with them, te the Gardens
with One Companion daily.

They may also obtain a TransFeRaBLe Ivory Ticker admitting
Two Persons, available throughout the whole period of Fellowship,
on payment of Ten Pounds in one sum. A second similar ticket
may be obtained on payment of a further sum of Twenty Pounds.

Any Fettow who intends to be absent from the United Kingdom
during the space of one year or more, may, upon giving to the
Secretary notice in writing, have his name placed upon the

+

“ dormant list,” and will be thereupon exempt from the payment of
his annual contribution during such absence.

Any Fettow, having paid all fees due to the Society, is at liberty to
withdraw his name upon giving notice in writing to the Secretary.

The Secretary read the following report on the additions to the
nate Menagerie during the months of November and December
1891 :—

The total number of registered additions to the Society’s Mena-
gerie during the month of November was 45, of which 20 were by
presentation, 1 by birth, 15 by purchase, and 9 on deposit. The
total number of departures during the same period, by death and
removals, was 91.

Amongst these attention may be called to the four Spotted-billed
Pelicans (Pelecanus muanillensis), received from Calcutta. This
species, which is new to us, is a close ally of the African P. rufescens.
When the birds come into full plumage we shall. be able to see how
far they differ from their African relative.

The registered additions to the Society’s Menagerie during the
month of December 1891 were 82 in number. Of these 71 were
acquired by presentation, 8 by purchase, and 3 by exchange. The
total number of departures during the same period, by death and re-
movals, was 74.

Amongst these special attention may be called to the second
specimen we have received of the Formosan Fruit-Bat (Péeropus
morsus), of which the original specimen was received in January,
1873 (see P. Z.S. 1873, p. 192, pl. xxii"). The present example

oe died Oct. 4, 1879, and was acquired by the British Museum.

was presented to the Society by Thomas Perkins, Esq., F.Z.S.,
Dec. Ist, 1891.

Dr. E. C. Stirling, C.M.Z.S., exhibited some specimens of the
new Australian Marsupial (Notoryctes typhlops), and gave a short
account of the habits of this remarkable animal, as observed in a
specimen recently kept in captivity by one of his correspondents.

The following extract was read from a letter received by the
Secretary from Dr. F. A. Jentink, F.M.Z.S., dated Leyden,
4th December, 1891 :—

“In a paper published September 1890 (Notes from the Leyden
Museum, p. 222) I called the attention of naturalists to the re-
markable Bush-rat, Pithechir melanurus, from Java and Sumatra.
The type of this black-tailed red Rat is a drawing in colours, by
Duvaucel, reproduced in Cuvier's ‘ Mammiféres.’ No specimen of
the Pithechir melanurus is in the Paris Museum, nor has it ever
been observed by a naturalist, except by the late Dr. S. Miiller, who
procured in 1834 two skins from Padang and Batavia for the Leyden
Museum, where they are still preserved. I think it will highly
interest the members of the Zoological Society to know that I have
just received a postcard from Mr. Pasteur, of Batavia, announcing
that he has in his possession a whole family (¢, 2 and young) of
P. melanurus, captured in the neighbourhood of Batavia, which he
intends to present to our Museum. Within a few weeks, I hope to
get them, preserved in spirit, and to be able to give a more detailed
description of the specimens and their skeletons &c.”

Mr. Ernst Hartert exhibited 31 clutches of eggs of different birds’
eggs associated with eggs of Cuculus canorus, mostly collected by
himself and reliable friends. He made remarks about the mimicry
of the egg in the Cuculide, and observed that some of the Indian
species of this family illustrate this fact much better than the
European Cuckoo. -

Although attempts had been made to prove the contrary, one
individual female Cuckoo in his opinion always laid similarly coloured
eggs. To prove this fact he called attention to several series of eggs
that had apparently been laid by one female. In every case the
eggs of the same female were entirely similar to each other in form,
size, and colour.

As a very remarkable fact Mr. Hartert mentioned that as regards
the dark closed nests of the Common Wren uo adaptation of the egg
of the Cuckoo to the eggs of the owner had ever been noticed.

NEW TUNISIAN REPTILES.

1892.] | ON MAMMALS, REPTILES, ETC. FROM BARBARY. 3

1. On a small Collection of Mammals, Reptiles, and
Batrachians from Barbary. By Jonn AnpeErson, M.D.,

LL.D., F.RB.S.
[Received November 51, 1891.]
(Plate I.)

The Mammals, Reptiles, and Batrachians enumerated in the
following notes were obtained either by myself in Algeria and
Tunisia, or by my collector at Duirat, in the latter region, on the
confines of Tripoli. But besides these, several species of Reptiles
from the Sahara, purchased from a collector at Biskra’, are also
included in the list. The specimens collected by me were acquired
between December and the beginning of May, and those captured
by my collector between the middle of May and the end of June.”

The weather experienced in Algeria, in the winter and spring of
1889-90, was very unfavourable to collecting natural history speci-
mens, and more especially reptiles. In Algiers itself, from the end
of November until the 7th February, there was a succession of
rainless intervals followed by protracted periods of wet weather
accompanied with high winds, and so cold that fires were indis-
pensable while the wet weather lasted. During these storms what
fell as rain in the lower altitudes of the Tell, came down as snow
on the Atlas and the high plateaux, a cold wind blowing from off
their heights. On the 10th February I encountered snow a metre
in depth on Mount Beni Salah (5379 ft.) above Blidah, at an
elevation of about 1200 to 1500 ft. below the summit; and M. Lataste
records that, on the 22nd April 1881, the rain and hail that fell at
that elevation on this mountain prevented him from passing beyond
the farm called La Glaciére, where snow is stored for use in summer
at Algiers, ‘This bad weather was not confined to the neighbourhood
of Algiers, because, while there, there were constant reports coming
in of heavy snow in Kabylia, at Setif, Constantine, and Batna, and
indeed over the high plateaux generally, these storms occasionally
making themselves felt as far south as Biskra, whence it was reported

1 The localities in which the specimens had been captured were in every
instance carefully noted on the bottles.

2 The following is a list of the localities visited by me, with the altitudes of
some of them, and the date when I was at each :—Algiers, Noy.-7 Feb. ; Blidah,

4 DR. J. ANDERSON ON MAMMALS, REPTILES, [Jan. 5,

that a heavy fall of rain had caused the collapse of some of the mud-
houses of that oasis. While at Tlemcen, in the beginning of March,
after experiencing two delightful days of bright sunshine, during
which lizards began to show themselves, we were driven from it by
a storm of rain and sleet, accompanied by a biting wind from the
south-west, the direction from which these storms generally came,
that lasted for two days. About this period, the railways that run
southwards from Oran to the Sahara were blocked with snow. At
Oran the weather was equally unsettled, clear intervals of sunshine
alternating with days of heavy rain. At Milianah, on the morning
of the 18th March, we awoke to find the tops of the houses and
the ground covered with snow, and, during a previous storm,
towards the end of February, snow had fallen as low as Hammam
R’irha. At Algiers we were delayed for thirteen days (19th March
to 31st), waiting until the snow had disappeared from the
mountain in Kabylia on which Fort National stands. At Kharata,
at the head of the gorge Chabet el Akhira, we were storm-stayed for
three days, as torrential rains, lasting for two days, had carried away
parts of the road behind and in front of us. When we had arrived
on the treeless plateau on which Setif stands, the frost was so intense
on the morning (10th April) on which we left it, that every pool was
frozen. The evening of the day following our arrival at Biskra, the
wind rose with violence from the north accompanied by heavy rain
which continued through the night and part of the next day. The
Oued Biskra was so flooded by this storm from the Aures mountains,
that the route to Sidi Okha which lies across it was closed for a
day. My experience of an Algerian winter I was told was quite
exceptional ; but, since my return to this country, I have studied
with interest the reports of the weather experienced in Algeria last
winter, and I fiad that it has been even more exceptional than the pre-
vious winter. Snow fell in Algiers itself, and so heavily in Tunisia that
aative houses broke down under its weight, while some deaths from
cold were recorded. In the west also it was very severe, as some
anxiety was felt, during cne of the storms, for an outlying village
near Tlemgen which had become completely isolated, by reason of
the snow that surrounded it. In connection with these observations
on the winter climate of Algeria, I observe M. Lataste mentions the
spring of 1881 was so little advanced by the middle of May, when
he was at Bougie, that he was compelled to turn southwards. It
was only when we had travelled as far west as Hammam Meskoutine,
removed somewhat from the direct influence of the storms that come
up from the Atlantic, that we began to experience genial weather and
bright sunshine, under the influence of which snakes and lizards vegan
to shake off the torpidity of winter, and by the time we had reached
Tunis, 30th April, the heat in the sun had become so great that I
abandoned the intention I had formed of going to Duirat, and sent
my collector there instead.

I have given these details regarding the weather encountered in
Algeria in 1889-90 because the character of the winter climate
does not appear generally known, and as they serve to explain, to a

great degree, why the collection of reptiles made by me is so com-
paratively meagre.

M. Lataste, the most recent and successful investigator of the
Vertebrate fauna of Barbary, has recorded his observations on the
Mammalia inhabiting that region in two works’. He has been able,
by his collections and extensive researches in the country and by the
labours of other naturalists, to bring up the number of Mammalian
species inhabiting Barbary to 84.

Among the eleven species of small Mammalia found by me the
only one calling for special remark is Plecotus auritus, obtained by
my collector in considerable numbers at Duirat. The interest
attached to these specimens is that, while the species is an addition
to the fauna of Tunisia, it is only the second time that it
has been reported from Barbary. M. Loche had observed a specimen
in the flesh, at Blidah, in the hands of a child who had caught it ;
but M. Lataste was of the opinion that the species was one of eight
included by M. Loche in his list of Mammals of Algeria, all of
which would probably be ultimately erased from the list. This
however, is included by M. Lataste in his Catalogue along with the
other seven. .

Another valuable result of M. Lataste’s labours was read before this
Society on the 18th November last. I refer to Mr. Boulenger’s
“ Catalogue of the Reptiles and Batrachia of Barbary, based chiefly
upon the notes and collections made by M. Lataste in 1880-84.”
Long before his Catalogue was finally printed off, Mr. Boulenger
very kindly gave me the use of a set of proofs to assist me in naming
my specimens, and by their aid, and by means of the excellent keys
and concise descriptions embodied in the Catalogue, the identification
of the specimens was easily accomplished, even in so difficult a genus
as Acanthodactylus.

Moreover, as the specimens, after they had been referred to their
respective species, were compared with the representatives of the
species in the British Museum, I have every confidence that each
has been correctly named.

Mr. Boulenger’s Catalogue enumerates 64 species of Reptiles and
10 species of Batrachians, whereas my small collection contains only
33 Reptiles and six ecaudate Batrachians, none of the caudate forms
having been obtained. Mr. Boulenger has given a most instructive
list illustrating in tabular form the distribution of the Reptilia and
Batrachia of Barbary ; and the only addition these specimens make
to it is the extension of the range of Lacerta ocellata, var. tangitana,
to the Tell region of Algeria, in the Province of Oran.

At Duirat, in Tunisia, a locality where apparently forms distinc-
tive of the Tell and of the fauna of the Sahara meet, and which in
position seems to bear much the same relation to the Tunisian desert
that Biskra has to the Algerian Sahara, my collector obtained one

well-marked new species of the genus Chalcides, of which I give a
description and three figures, accompanied, for the sake of comparison,
by two views of the head of its nearest ally, C. sepoides, Audouin.
At the same place my collector also found a Viper distinctly
referable to V. lebetina, but, at the same time, differing so much
from the typical form, in some of the details of its structure, that I
have had no other course left me but to describe it as a variety.

* The wing and interfemoral membranes of one of these Bats are torn and
shrivelled up in places along the margins to such an extent that the flight of
the animal must have been materially affected by it, Here and there over the
surfaces of the membranes, and elsewhere on the body, there are dense colonies
of a minute white Acarws, and it seems probable that the irritation produced by
them had set up inflammation resulting in the partial destruction of the mem-
branes, which also, when held against the light, were seen to be covered with
small black spots, doubtless old inflamed areas due to the same cause. Mr. A.
Michael kindly undertook to determine the nature of these Acari. The following
are his remarks :—

“The Acari submitted to me belong to two species only, and are all immature.

2 S$ & 2 9, Duirat, Tunisia; 19, hills behind Biskra.

This species has been found at Mount Santa Cruz, Oran (in the
Tell), whence also probably came the specimen from which Duvernoy
described the species. It likewise inhabits the high plateaux, and has
been recorded from (north to south) Ain Oussera, about 3000 ft.
above the sea, Djelfa, 3792 ft., Ain el Ibel, about 3700 ft., and also
from the slopes tending to the Sahara, such as Laghouat, 2437 ft.,
and Bou Siiada, 1900 ft. The specimen recorded by me from Biskra,
360 ft. above the sea-level, was not obtained at this elevation, but
from the hills behind, at what height I cannot say. M. Lataste

belongs to the genus Hyalomma (Koch). The species seems to be either the
Ixodes flavipes of Koch or the £. vespertilionis of the same author; it is not
possible in the present state of our knowledge to identify it with certainty
from immature specimens, but it is probable that the two species are not
really distinct ; both have been recorded as bat-parasites, the former by Kolenati,
the latter by Koch. According to modern classification this Acarid would
belong to the genus Hyalomma, not Ixodes.

“he other Acarid, of which there are numerous examples, was found by
Dr. Anderson upon the same Bat and upon Plecotus awritus; it is one of the
creatures described by Kolenati as forming the genus Peplonyssus; the species
is probably his P. cruciplica. These Peplonyssi are all bat-parasites; but,
although I am not sure that the fact has been publicly recorded, I think there
can be no doubt that all the species of the genus are larval forms of Ixodide,
the adults of which we may or may not be acquainted with, but which cannot
at present be identified with the larve.”

8 DR. J. ANDERSON ON MAMMALS, REPTILES, [Jan. 5,

has recorded it from Batna, 3350 ft., on the high plateaux imme-
diately to the north of Biskra, and he has mentioned specimens from
the region of the Tunisian Chotts, Feriana and Djebel Bou-Hedma,
Tunisia, but none so far from the east as Duirat.

The female from Biskra I had alive in my possession from the 17th
April until the 22nd May. I brought it alive to Switzerland, but,
after it had been eight days in Europe, it died, possibly from eating
food unsuited to it. In Algeria, but more especially in Tunis, I
experienced no difficulty in obtaining house-flies wherewith to feed
it, and on which it throve, but, on my arrival in Europe, these
insects were so scarce that I had first to offer it the larvee on which
bird-fanciers feed small insectivorous birds. These it ate for a day
or two, but, as it afterwards refused to touch them, I had next to
try it with small cockroaches. These, however, did not appear to
agree with it, and in two days more it was dead.

It was very expert in catching flies, and as it never attempted to
jump off any great height, I used to place it on a table, covered
with a white cloth, and to scatter maimed flies over the table. When
it once caught sight of a fly it made a rapid rush at it, the mobile
proboscis touched the fly, and it disappeared, the Shrew seldom
allowing one to escape. The tongue is remarkably long, exceeding
the length of the snout, on the under surface of which there is a
well-marked groove along which possibly the tongue is projected,
assisting in the seizure of the insect prey. In its natural haunts,
ee proboscis is probably introduced into crevices where insects
urk.

It was so tame that it was generally placed on the breakfast table,
on which it ran perfectly at home, occasionally picking up minute
hard crumbs from the outsides of “ croissants”’ or fragments of
biscuits. It used also to lap milk freely from a spoon, returning
every now and again to doso, and, if it had had its own way, it would
have gorged itself with butter, but with disastrous effects, as a small
quantity acted on it as a laxative.

Its great delight while on the table was to get under a covert of
some kind, and to run from one shelter to another, now and again
darting out suddenly when it saw a fly. It never attempted to bite,
and it seemed to enjoy being held in the hands, the heat and cover
afforded by them being grateful to it. In this position it would re-
main for a long time, making no effort to move.

Its sense of hearing was acute, more especially to sharp sounds,
any shrill call at once startling it, whereas dull sounds it seemed to
heed but little. With regard to its vision, I may mention that while
it had a keen eye for small objects in motion, I could wave my arms
in front of it, a few feet off, without scaring it.

__ Its movements were extremely rapid, and in ordinary progression
it never jumped, but was projected forwards, so to speak, in short
runs, ever and anon stopping abruptly to look about.

There were two fcetuses in the right horn of the uterus of one of
these females, a similar number having been recorded by M. Lataste
in an individual which he examined. In his specimen they were

M. Lataste was the first to point out that the large lizard of
Algeria and Tunisia was a race or subspecies of J. ocellata, closely
related to it, but having also some points of affinity with L. viridis.
Mr. Boulenger adopts this view, with which I fully agree, and in
his catalogue he clearly indicates wherein it differs from the European
form.

In none of these specimens does the number of scales across the
back exceed 80, nor are the femoral pores more than 16.

1 young, Tlemgen, Province of Oran.

This variety was founded by Mr. Boulenger for the reception of
some lizards from Tangier, very nearly allied to the previous variety,
but differing from it and from L. ocellata typica in their much
smaller dorsal scales, numbering from 77 to 100 across the middle
of the body, and in their more numerous (17-21) femoral pores, On
the other hand, in their smaller occipital and in the number (6-8) of
the longitudinal rows of ventral scales, they manifest, as pointed out
by Mr. Boulenger, marked affinities to the Spanish-Portuguese form
of L. viridis, the var. schreiberi, Bedriaga, and so closely do they re-
semble it in these two respects that they are undistinguishable from
it. Until the discovery of these specimens from Tangier, L. ocellata
and ZL. viridis were unknown from Morocco. It is interesting
therefore to find the Morocco variety occurring at Tlemgen, but not
surprising, considering the proximity of this locality to Morocco.
This specimen, however, presents one variation by which it can be
distinguished from all the examples of var. ¢angitana in the
British Museum, and that is, that the shields along the collar are
much more numerous, being 22, whereas in vars. pater and tangitana
there are only 10 or 11 shields. This is not at all likely to be
an individual variation, and hence it is interesting to find the out-
lying members of the variety so modified.

The specimen in question is unfortunately young, as it measures
only 47 millim. from the snout to the vent, but in all its other cha-
racters it resembles var. tangitana. The dorsal scales are very small,
and number 87 across the middle of the body ; there are 18 femoral
pores, 8 longitudinal rows of scales on the belly, and the occipital
shield is decidedly narrower than the interparietal, all distinctive
features of L. ocellata, var. tangitana.

8. LaceRTA MURALIS, Laurenti; Boulenger, loc. cit. p. 125.

3 ¢ & 3 Q, Tlemcen, Province of Oran.

These lizards resemble the specimens of this species from Tangier
described by Mr. Boulenger as having the scales very small, obtusely
keeled and in 61 to 73 rows across the middle of the body, but in
some of them they fall to 56. Their upper caudal scales are also
strongly keeled as in specimeus from Tangier. The femoral pores
vary from 17 to 21, whereas in examples from the latter district they
vary from 13 to 19, 17 being the usual number.

One of the above males is coloured exactly like the specimens from
Tangier in the British Museum, but another and two females are
less spotted with black, and the white spots on the tail, so marked
in Tangier specimens, are absent, or only feebly indicated.

The ventral plates in these specimens do not exceed 10, and the

but this occurs only in one specimen, all the others having 10
longitudinal rows.

Five of the seven specimens have 23 femoral pores on each side,
one 19, and the other 24. The longitudinal series of scales round
the middle of the body vary from 30 to 36, the lowest number
occurring in a specimen from Duirat.

1g & 4 Q, Tuggurt; 3 ¢ & 2 9, Duirat, Tunisia.

These specimens are all distinguished by acute snouts, denticulated
ears, and by the dorsal and ventral scales merging the one into the
other, these scales conjointly varying from 60 to 70 (Mr. Boulenger
gives 61-74); the scales referable to the ventral region vary from
12 to 14, the latter number being dependent on the degree of
development of the outermost series of scales, but in Mr. Boulenger’s
specimens the number rose to 18. The lowest number of femoral
pores, 18, occurs in a female specimen from Tuggurt, whereas the
highest number 26, is found in a male from Duirat, the range of
femoral pores recorded by Mr. Boulenger being from 18 to 25.

The three males from Duirat are reddish, with numerous black
spots and indications of white ocelli on the sides, whereas the
females from the same locality are uniformly reddish, with the white
ocelli feebly visible, and the black spots only faintly traceable here
and there. The Tuggurt specimens are olive-grey. In the male
from this locality the black spots are more distinctly marked than
in the females.

1892.] AND BATRACHIANS FROM BARBARY. 15

The specimens from the first-mentioned locality belong to the variety
named bedriage by M. Lataste, whilst the others, which are distin-
guished from them by being more slender and somewhat smaller,
may be taken as representing the variety deserti (Zootoca deserti,
Giinther). However, as Mr. Boulenger points out, not only are
these varieties ill-defined, but the former approaches A. vulgaris in
its structure and coloration, whilst the latter often closely resembles
= scutellatus. This species (A. pardalis) is thus a transitional
orm.

Among the specimens recorded above, the scales round the middle
of the body, including the ventrals, vary from 61-74, whereas in
Mr. Boulenger’s specimens the variation is from 66-82. The
femoral pores also are variable, as in my specimens the lowest
number is 15 and the highest 22, whilst the numbers recorded by
him are 15-25.

loc. cit. p. 131.

4 g¢ & 3 2, Mount Santa Cruz. On old walls at the foot of the

In these specimens the subocular enters the labial border, and in
five out of the seven it does so more or less broadly. In one of the
remaining two the sharp lower angle of the shield is wedged in
between the labials as a fine point, while in the seventh specimen it
is excluded from the labial border on one side, but preserves the same
character as the previous specimen on the opposite side. Unlike
Moroccan examples of this lizard, the tendency of this shield is to
enter largely into the formation of the lip.

In none of the specimens does the number of the scales round the
body, including the ventrals (8), exceed 77, nor fall lower than 73.
The femoral pores vary from 23 to 26.

They are marked with six longitudinal whitish lines, separated from
each other by broad dark brown bands ; but in the largest specimen
the white lines are more or less broken up into white spots, the
intervening dark bands being reticulated with brick-red. The limbs
are white spotted, and the end of the tail is pink.

These three specimens have the median disk of the eyelid broken
up into 4, 5, and 6 scales respectively, with the collar distinct only
at the sides. In the variations tabulated by Mr. Boulenger, the
form with the collar distinct at the sides has only two scales in the
transparent palpebral disk, the highest number, four, recorded by him
occurring in specimens with the collar free all round. In specimens
presenting these two kinds of variation in the collar and in the

16 DR. J. ANDERSON ON MAMMALS, REPTILES, [Jan. 5,

palpebral disk, the number of scales round the middle of the body is
52, the femoral pores being 10-10 in the first variation, and 11-10
in the second, whereas in my specimens the scales round the body
(including the yentrals) are 52-53, and the femoral pores are 11-14.
In Mr. Boulenger’s specimens with six scales in the palpebral disk,
and with the collar distinct and attached in the middle, the femoral
pores are 14—13, while in the above-mentioned specimen, with the same
number of scales in the palpebral disk, there are only 11 femoral
pores, associated with 53 scales (including the ventrals) round the
body, whilst his specimens have 59 scales. Mr. Boulenger indi-
cates another variation with 3 scales in the palpebral disk, 68 scales
(including ventrals) round the body, and with 17-17 femoral pores.
These facts attest the correctness of M. Lataste’s opinion, which
Mr. Boulenger shares, that no division of this species into subspecies
or varieties can be made on characters derived from the palpebral
disk and collar.

brown to dark grey, without any trace of the broad dorsal band of
a darker hue which occurs in all the Biskra specimens, none of which
are of a grey tint. In some specimens from Biskra the ocelli are

Snout wedge-shaped, not so broad as in C. sepoides, Audouin,
but with a projecting labial edge ; eye small, but slightly larger than
in C. sepoides ; ear-opening an oblique slit at the commissure of the
mouth, but with a fringe of three pointed scales. The nostril is not
in advance of the suture between the rostral and the first labial ;
supranasals fused into a single shield; frontal as broad or a little
broader than long ; four supraoculars, with four small scales below
them ; fifth labial enters the orbit. The limbs are weak, but stronger
than in C. sepoides; the hinder pair are proportionally more deve-
loped than the front limbs. The hind limbs are penta- or tetra-
dactyle, and in length each equals about the distance between the
fore limb and the nostril; the latter limb equals considerably more
than half its distance from the centre of the eye, and is pentadactyle *.
The body is not quite so long as in C. sepoides, and the sides are
angular as in that species. Twenty-eight rows of scales round the
body.

Yellowish above, each scale finely margined with dark brown, their
centres whitish and presenting, in some instances, the appearance of
ocelli, recalling the ocellation characteristic of C. ocellatus, and this
is unmistakably marked especially on the tail, on which the ocelli
are arranged in more or less transverse rows. A black line through
the eye, and two fine black lines on either side of the frontal. The

This species is distinguished from C. sepoides (Plate I. figs. 4, 5)
by the nostril not being placed inadvance of the suture between the first
labial and the rostral; by the fifth labial entering the orbit, whereas
in C. sepoides it is the fourth that does so; and by 28 rows of scales
round the body, whilst in that species these scales never exceed 24.

The ear is much the same as in C. sepoides, but it is very different
from the ear of C. ocellatus and that of C. mionecton, in which it is
a round well-marked opeuing, further removed from the angle of the
mouth.

It is linked by the character of its labial edge and rostral to
C. sphenopsiformis (Senegambia), which through C. mionecton
connects it with C. ocellatus. It thus supplies a link that was
wanting in the chain of these species, so to speak.

I have much pleasure in connecting Mr. Boulenger’s name with
this new lizard from Barbary.

from the parietal region forwards to the rostral perfectly smooth, I
regard it as a variety which I propose to call deseréi. ;

All authors who have hitherto had occasion to describe V. lebetina
from Algeria have either directly or indirectly referred to the keeled
character of the head-scales. Through the kind assistance of Mr.
Boulenger, who examined fcr me the type (No. 4017) of V. mauri-
tunica, Guichenot, in the Paris Museum, I have his authority for
stating that the canthus rostralis of that snake is well marked, and
that the interorbital scales are feebly but distinctly keeled. It has
no large supraoculars, and the rostral is a little higher than broad.
It isa female with 163-ventrals and 50 caudals. Another and
young specimen, No. 4016 of Guichenot’s Collection, is the same as
the preceding, but with the canthus rostralis less distinctly marked.
It has 166 ventrals and 39 cauJals.

I have examined all the specimens of V. /ebetina in the British
Museum, and I give the leading details regarding them in the
following table, and for comparison I have added in the last column
those yielded by this variety.

22 DR. J. ANDERSON ON MAMMALS, REPTILES, (Jan. 5,

I have also given two drawings of its head (Plate I. figs. 6, 7).
If these are compared with Guichenot’s figure of V. mauritanica’,
which Mr. Boulenger informs me is a good representation of the
above-mentioned specimen No. 4017, the differences between this
variety and the typical form will be seen to be considerable.

To summarize the features of this variety, the most striking is
certainly the entire absence of any approach to keeling on the scales
on the upper surface of the head from the parietal region forward to
the rostral. As already stated, in all the hitherto recorded speci-
mens of V. lebetina, the scales of the head over the foregoing area
and over the upper surface of the head generally are keeled in various
degrees of intensity, while at the same time they preserve to a great
extent the general form and character of the scales on the body. In
this variety, on the other hand, the head-scales, besides being
perfectly smooth in the region specified, are somewhat unlike those
of the body in that they are rounded at their margins and are very
flat. The entire absence of the canthus rostralis is another feature
by which this variety is distinguished from the typical form, in which
it is always defined although less marked in some individuals than
in others.

The rostral shield is higher than broad, but in an example of this
species from the Lake of Galilee it is as high as broad, a modifica-
tion which connects this variety with the other specimens mentioned
in the foregoing table in which the rostral is decidedly broader than
high. The supraoculars in the first six specimens enumerated in the
table (p. 21) are not markedly differentiated from the ordinary head-
scales as regards their size: occasionally one or more scales may be
larger than the others, either on both sides of the head or on one only,
but in none of them are two scales so developed as in this variety.
On the other hand, the specimens from Persia and Afghanistan can be
distinguished at once by the presence of a large supraocular occupying
nearly the entire upper border of the eye. It will be observed that,
in the labials and the scales between the eyes, the variations among
these specimens are very insignificant. It is worthy of attention
that the four specimens from the mainland of South-western Asia
present a marked increase in the number of their ventrals as com-
pared with the typical form from Algeria and Cyprus, and that the
two groups are connected with each other by var. deserti from Eastern
Tunisia.

In VJ. lebetina, var. deserti, the colour is pale yellowish brown
above, with very faint indications of the dorsal and lateral dark spots
distinctive of Algerian and Cyprian examples of the typical form ;
and the under surface is pale yellow, almost immaculate anteriorly,
the finely powdered aspect of the species being only feebly indicated
posteriorly. The specimen from the, Lake of Galilee very much
resembles the var. deserti in colour and general appearance, but it
has keeled scales on the head and a canthus rostralis.

I have selected the term desertz to designate this variety, because
reptiles received from Duirat, the locality from which this Viper

1 Explor. Se. Alg., Rept. pl. ii.

1892.] AND BATRACHIANS FROM BARBARY. 23

was obtained, establish the fact that the Saharian fauna extends to
as district, and moreover the Snake has all the features of a desert
orm.

The majority of the specimens of V. lebetina hitherto recorded
have come from the Tell region of Western Algeria, but examples of
this species have also been mentioned from Batna on the high plateau
ard likewise from Bona on the coast, in the Tell region. As our
knowledge of the northern portion of the Sahara intervening between
Duirat and Egypt becomes more extended, it is probable that this
variety of V. lebetina will be found to occur throughout that district,
and, possibly, in Egypt itself.

2. On the Myriopoda and Arachnida collected by
Dr. Anderson in Algeria and Tunisia. By R. I. Pocock.

{Received January 11, 1892.]

The Myriopoda collected by Dr. Anderson during his stay in
Algeria and Tunisia in the winter of 1890 and 1891 are refer-
able to 21 species, one of which appears to be new. ‘This, which
I call Brachydesmus insculptus, seems to be very nearly related to
a species that was described two years ago by Dr. Latzel from the
Azores. This fact is of interest, inasmuch as it affords another link to
the chain of affinity between the fauna of these islands and that of
the Mediterranean district of the Palzearctic region.

The rest of the species are principally remarkable for the light

1892.] ARACHNIDA FROM ALGERIA AND TUNISIA. 25

that they throw upon the synonymy of old-established but little-
known species.

The only circumstance to be noticed here with respect to the
Arachnida is the vast amount of variation shown by the sexes and
young of the Scorpion, Prionurus australis.

ARACHNIDA.

The only species of this group obtained by Dr. Anderson are the
following :—Galeodes olivieri, Simon, Prionurus australis (Jinn.),
Buthus europeus (Linn.), and Buthus leptochelys (Ehrb.). All of
them are well-known N.-African forms, but I am not aware that
B. leptochelys has been ere this recorded go far to the West.

The species were obtained at the following localities :—Galeodes
oliviert between Biskra and Tuggurt ; Prionurus australis, Duirat,
Biskra, Tuggurt ; Buthus europeus, Algiers, Hammam Meskoutine,
Hammam R’irha; Buthus leptochelys, Biskra.

Fam. SCOLOPENDRIDE.
ScoLOPENDRA MoRSITANS, Linn.
The North-African form of the cosmopolitan S. morsitans was
described by Koch as S. scopoliana and by Newport as S. algerina.

At these localities Dr. Anderson obtained three examples of

26 MR. R. I. POCOCK ON MYRIOPODA AND [Jan. 5,

a species of Scolopendra, which agree closely with Lucas’s figure
and description of S. oraniensis, and at the same time are not specific-
ally distinguishable from the S.-European S. dalmatica; Lucas’s name
must consequently supersede that of Koch.

The two specimens captured at Hammam B’irha are smaller and
very dark-coloured, being an exceedingly deep green. The Tunisian
example, on the contrary, is very much paler and considerably
larger.

CupPIPES GERVAISIANUS (Koch).

It is needless to repeat here the involved synonymy of this species,

This species also occurs in S. Europe.

The above-given synonymy was published by me before it had been
my good fortune to examine a specimen of this species from the locality
where the types of O. deserti were obtained. Dr. Anderson, how-
ever, has supplied the missing link in the chain of evidence by
procuring a specimen from Biskra. This example is undoubtedly
co-specific with Newport’s types of B. spinicauda and also with those
that Meinert described as O. deserti.

This species is not known to occur in Europe.

This species is the punctatus of Koch and all authors ; see my
paper on the Chilopoda of Liguria, in the Ann. Mus. Genoyv. (2)

described as C. numidicus; but to this last were assigned only 12

3. On the Earthworms collected in Algeria and Tunisia by
Dr. Anderson. By Franx E, Bepparp, M.A., Pro-
sector to the Society.

[Received January 5, 1892.]

As nothing appears to be known of the Earthworms of the
northern part of the African Continent, excepting Egypt, I am very
glad to have had the opportunity, afforded me by Dr. Anderson’s
kindness, of examining a small collection made by him during the
spring of last year in Algeria and Tunisia.

Earthworms show in so yery plain a manner the effect of barriers
to dispersal in their distribution, that I had expected to find the
Algerian forms identical with or closely allied to those of Europe.
The Earthworm-fauna of Central‘and South Africa is evidently very

1892.] FROM ALGERIA AND TUNISIA. 29

rich, though at present but little known ; but the Sahara has proved
here, as it has in the case of other animals, to be a barrier preventing
the northward range of these forms. Only in Egypt are there any
genera found also in Tropical Africa; the very remarkable genus
Siphonogaster occurs in Egypt and in the neighbourhood of Lagos,
W. Africa. But the banks of the Nile, or even the river itself (for
many species of Earthworms can withstand a prolonged immersion in
fresh water), have furnished, no doubt, the opportunity of migration.

Mr. Alvan Millson, Colonial Secretary at Lagos, kindly collected
for me a number of Earthworms in Egypt; all these species were
members of the genera Lumbricus and Allolobophora.

Besides Levinsen’s paper upon Siphonogaster and Digitibranchus
(=Alma) we do not possess, I believe, any further information upon
the Oligochzta of Egypt than that which has been given in the
preceding sentence.

Dr. Anderson’s collection contains examples of two recognizable
species, Adlolobophoracomplanata and Microscolex modestus. Besides
these, there are two or three immature forms of the genus ddlolo-
bophora which are not old enough for identification.

ALLOLOBOPHORA COMPLANATA (Dugts).

Iumbricus complanatus, Dugés, Ann. Sci. Nat. t. vill. pp. 17, 22.

This species is a well-known South-European form, having been
met with in S. France, Italy, Portugal, and the Balearic Islands.
I now add Algeria to the list of localities whence it has been ob-
tained. The principal information as to the structure of this species
is to be found in Dugés’s memoir upon the Earthworm, in Rosa’s
account of the Lumbricids of Piedmont *, and in a paper by myself
devoted to this species *. In neither of two specimens belonging to
Dr. Anderson which I dissected was there any trace of the peculiar
diverticula of the spermathecee which I described in the paper last
referred to.

As neither Dugés nor Rosa observed anything of the kind, it is
possible that the individual I described should be regarded as a
variety of the more typical form, the occurrence of which in Algeria
I here record.

MicroscoLex ALGERIENSIS, 0. Sp.

There is only a single specimen of this species, which I investi-
gated by means of longitudinal sections of the head end. The
structure of the posterior segments was examined by mounting
portions of the body in glycerine after having been cut open.

It is a small worm, measuring only an inch or so in length and
composed of 80-90 segments. Being curled into a circle in the
preservation, [ am not able to give exact measurements, which are,
however, not of very great importance. '

Roy. Soe. Edinb. xiii. p. 451.

30 MR. F. E. BEDDARD ON EARTHWORMS [Jan. 5,

The prostomium is large, being larger than the diameter of the
first segment.

The sete are disposed precisely as in Microscolex modestus : that
is to say, the setae are not in closely approximated pairs, and the
distance between seta | and seta 2 is less than that between sete 3
and 4. The diagram given by Rosa of the setee of M. modestus
would express, so far as I can make out, the relations of the set in
M. algeriensis exactly. There is nothing noteworthy in the form of
the sete. As in other Earthworms, the four sete of each side of the
body in each segment are connected by muscular strands which
favours, it may be supposed, their simultaneous movement. This
muscle in Microscolez is easily overlooked, owing to its great thin-
ness; it is not more than two fibres thick.

The clitellum is complete (forming, that is, a ring) and occupies
segments xiv.—xvii. with a part of xiii. Its structure is like that of
other Earthworms.

I could find no dorsal pores.

The alimentary tract is peculiar from the absence of a gizzard, of
which traces appear to exist in other species of Microscolex ; for in
M. dubius Rosa speaks of “un ventriglio rudimentale, piatto, in
forma di coppa;”’ as to the only other known form, Microscolexr
modestus, Rosa found that “il ventriglio esiste, ma cosi rudimentale
da non potersene veder le traccie che nelle sezioni.” It is not always
possible to detect the presence or absence of a gizzard without
having recourse to section cutting. Pontodrilus, for example, is
stated by Perrier to be without this special region of the ceso-
phagus ; but it is obviously present, though certainly much reduced,
when the anterior region of the worm’s body is examined by means
of sections.

The pharynx ends in the third or fourth segment, and, as in other
Earthworms, there are masses of glands upon the dorsal surface.
These glands, which seem to represent a part of the system of septal
glands in the lower Oligocheeta, are not confined, in Microscolex
algeriensis, to the pharyngeal region of the alimentary tract ; they
extend back as far as the ninth segment, and therefore suggest
more clearly the septal glands, with which they must surely be
homologous. It is interesting to recall the fact that these glands
occur also in Ocnerodrilus, which is another form near to the border
line between the terricolous and limicolous Oligochzeta, though
nearer to the latter than is Mieroscolex.

The esophagus of Microscolex algeriensis is divided into two
regions; up to the end of segment vii. it is not markedly vascular,
and the living epithelium is composed of more densely packed cells,
which gives it a more deeply stained appearance under the micro-
scope. The rest of the cesophagus has a richly-developed vascular
network, and the epithelium, appears to have a looser texture, the
cells being less tightly packed; from this circumstance the posterior
region of the cesophagus looks paler in sections. In the xvth
segment the cesophagus becomes much narrower and then suddenly
widens into the intestine which commences in the xvith segment.

1892.] FROM ALGERIA AND TUNISIA. 31

The intestine has no typhlosole. The intersegmental septa are first
visible after segment v. Those separating segments vii./vill., vili./ix.,
ix./x., x./Xi., xi./xii., xii./xili. are thicker than the following ones.
Their insertion ventrally does not correspond with the interseg-
mental furrows, and this absence of correspondence is found also
further back. It is by no means unknown in other Earthworms,
and is, as a rule, limited tothe anterior segments. Microscolex alge-
riensis has nephridia in all segments of the body commencing with
the second. They are paired and open in front of and a little to
the outside of the third seta. In dissection the nephridia are seen
to lie between the second and third setze on each side. There is a
long muscular end-sac, which in section was invariably much crumpled
owing to the thinness of its walls.

' The series of nephridia in this species is more complete than in
either of the cther two species of the genus. It is important to
notice that after the xviith segment the nephridia have a thickish
coating of peritoneal cells. A difference of this kind often exsist
between the anterior and posterior nephridia in Earthworms, though
nothing of the kind has been mentioned by Rosa in this particular
genus.

With regard to the vascular system the most noteworthy point
is the presence of three pairs of ‘ hearts’’ in segments x., xi., and
xii. There are pericesophageal vessels in some of the segments
anterior to the xth, but these are not so well developed as those of
the three segments mentioned. The hearts of segment xii. are by
far the stoutest ; their diameter is at least twice that of the preceding
vessels, which are themselves of rather greater calibre than those of
segment x. There is no sub-nervian vessel.

The drain is situated in the second segment, near to its posterior
boundary; the forward position of the brain is of interest.

The generative system conforms to the general type met with
among the Cryptodrilide. The testes are two pairs in segments x.
and xi. Opposite to them are the not remarkably large funnels
of the vasa deferentia ; the testes of segment xi. are partly attached
to the vas deferens just where it perforates the segment. The
sperm-sacs are in segments xi. and xii.; they involve neither the
testes nor the funnels. The two vasa deferentia of each side of the
body remain perfectly distinct from each other up to their point of
opening on to the exterior. The two tubes run side by side in a
rather sinuous course, just below the peritoneum. In the xviith
segment are a pair of ‘‘ prostates,” or, as I prefer to call them, atria.
They are of the tubular form, and, as usual, are separated into a
glandular and a muscular portion. The minute structure of this
tube is precisely as in Acanthodrilus, Pontodrilus, &c. The atria
are not long, and are entirely contained within the xviith segment,
instead of being, as is frequently the case, prolonged into adjoining
segments. The exact mode in which the vasa deferentia open, I
have not been able to ascertain. In any case the two tubes, still
retaining their individuality, bore their way into the body-wall a
little in front of the point where the atrium opens; they then pass

32 MR. F, E. BEDDARD ON EARTHWORMS [Jan. 5,

beyond the atrium, and, I imagine, open just at the atriopore, as
in Ocnerodrilas ; but I am not certain about this. The atriopore
is situated just to the outside of the ventralmost seta, which is not
modified in any way; there are, in fact, no penial setee, such as
occur in the other two species of the genus.

The ovaries are in segment xiii. ‘The oviducts open by funnels
into this segment opposite to the ovaries, and open to the exterior on
segment xiv. Receptacula ovorum are present, and are of consi-
derable size relatively to the sperm-sacs.

There is a single pair of spermatothece present in segment ix. ;
each opens on to the exterior just behind the septum which separates
this segment from the one in front and in a line with the ventral
seta. Each spermatotheca consists of an oval pouch and a single
narrow diverticulum opening into it in front.

MICROSCOLEX POULTONI, n. sp.

It may be permissible to append to this paper the description of a
fourth species of Microscolex, of which a number of examples were
kindly collected for me in Madeira by Mr. E. B. Poulton, F.R.S.
They measure, when preserved, about an inch in length; they are
of a brown colour, the clitellum being orange.

The clitellum is variable in extent, always, however, including
segments Xiv.—xvi.; in some specimens a part or the whole of seg-
ments xiii. and xvii. belonged also to the clitellum. Segments xiv.—
xvi. were much broader than those immediately adjoining.

The se¢@ are disposed as in other species of the genus; but upon
the clitellum the ventral pair of sets of each side get very much
closer together.

On segments xiv., xv., Xvi., and xviii. the ventral sets (see draw-
ing, fig. 1, p. 33) are separated from each other by a distance
which is less than half that which separates the corresponding sete
of segment x. From segment xix. backwards, and from segment
xiii. forwards, the distance between the two ventral setze of each
side gradually increases.

The male pores are upon segment xvii.; each is situated upon an
oval elevation, and through the aperture itself protrudes a single
penial seta, which corresponds in position to the innermost seta of
the ventral pair. The penial setz of this Microscolev are (see
fig. 2, p. 34) long, slightly curved, and not ornamented at the
free extremity ; when examived under a high power they show a
faint transverse striation which marks the successive deposits of
chitinous matter in the formation of the seta. There is a slight
notch some little way in front of the distal extremity.

The pharynx occupies the first 5 segments or so; there is not a
great development of glands upon its upper surface, and there is no
continuation of these septal glands into the cesophageal segments,
such as occurs in Microscolex algeriensis. The esophagus imme-
diately following the pharynx has, perhaps, slightly thicker walls
than the hinder part ; but there is nothing that can be fairly termed
a gizzard.

The epithelial lining of the wsophagus is folded; this folding is
perhaps more marked in segments xi., xii., and xiii. In segment
xv. the cesophagus forms a globular dilatation, the walls of which
are perfectly smooth without any folding; a very narrow aperture
puts this into communication with the intestine which commences
in the xvith segment.

In the terminal dilatation of the cesophagus, the epithelium

gradually gets higher until its cells are identical in appearance with
the tall narrow columnar cells which form the lining membrane of
the intestine. Just at the opening of the cesophagus into the in-
testine, the cilia are very long and conspicuous ; but the cesophageal

this point I could not be certain of the presence of cilia. The
intestine has no typhlosole.

The brain is situated further back in the body than in the last
species ; it lies towards the posterior boundary of segment iii.

pair, although they lie chiefly in segment iii. in front of the nerve-
cord, open on to the exterior between segments i. andii. On account
of the large terminal end sac, which is prolonged on both sides of
the aperture, and may be thus said to have a cecum, it is always
easy to make out the external aperture. I ara therefore able to be
confident about this point, which distinguishes the present species
from both Microscolea dubius and Microscolex modestus, and allies
it with Microscolex algeriensis. The external pore is to the inside,
and slightly in front, of seta 3’.

The three strongly developed hearts of segments x., xi., xii. are
present in Microscolex poultoni.

The generative organs show no great differences from those of
other species. Asin MV, algeriensis, the true vasa deferentia retain their
independence until close to the external aperture; they pass a
short way beyond the muscular duct of the atrium, and unite to
form one tube, which is surrounded with a thick layer of muscular
fibres chiefly circular; this tube is quite indistinguishable in its
structural characters from the muscular duct of the atrium; in a
section the two tubes cannot be distinguished except by their
position. In the thickness of the body-wall, and near to the
external pore, they unite. The penial set have already been
referred to.

The sperm-sacs are racemose, and occupy the same position as in
Microscolex algeriensis and all the other species of the genus.

The funnels of the sperm-ducts are larger and more folded than in
that species.

I could find neither spermatothecz nor egg-sacs.

This latter character connects Microscolex poultoni with M. dubius,
but it is quite clear from the above description that the species
described here is perfectly distinet from WM. dudius.

The principal differences are :—

(1) The fusion of vasa deferentia in MW. dubius to form one
tube, which opens into the muscular tube of its prostate.

(2) The commencement of the nephridia in the vth segment in
M. dubius.

(3) The absence of any alteration in the position of the seta
on the clitellum in MZ. dubius.

It shows much the same resemblances to M. dudius that WM. al-
geriensis shows to M. modestus. If Dr. Rosa were not so careful a
worker as he has proved himself, I should be almost inclined to
suspect an identity.

The genus WMicroscolea has been investigated by Rosa and
Fletcher. It was first met with in Italy by Dr. Rosa’, who, in a later

paper ', surmised that Fletcher’s* Zudrilus dubius would prove to be
a Microscolex. This suggestion was later® shown to be correct by
the description of a species of Microscolex evidently identical with
Eudrilus dubius from the Argentine. I received myself, some time
since, a number of examples of a Microscolex from Madeira, through
the kindness of Mr. E. B. Poulton, F.R.S., which are described
above. The existing knowledge of the distribution of the genus is
as follows :—

1. Microscolex modestus. Italy, Argentina.
2. Microscolex dubius. Australia, Argentina.
3. Dicroscolex algeriensis. Algiers.

4. Microscolex poultoni. Madeira.

The characters of MW. algeriensis evidently necessitate a revision
of Rosa’s generic definition given on p. 511 (3 of sep. copy) of his
memoir on the Argentine Earthworms.

The following points are, I think, sufficient to distinguish this
genus from any other genera among the Cryptodrilide.

The affinities of the genus have been discussed by Rosa, who com-
pares Microscolex with Photodrilus and Pontodrilus. I may point
out that the absence of penial sete in Microscolex algeriensis
lessens the distance between the genus and Pontodrilus.

The species which I describe here is quite clearly distinct from
the two others. The table (on p. 37) indicates the principal re-
semblances and differences between the four species Microscolex

(Plate II.) }
I. Historical.

The dentition of such an interesting Mammal as Hyraz, as may
readily be supposed, has been carefully studied by many zoologists,
who, probably owing to the fact that many of them based their
descriptions upon one or two dried skulls only, have given the most
varied interpretations of the teeth. As a result we find a great
discrepancy in the dental formule given in their various monographs
and in the text-books compiled from them.

Most of the earlier authorities agreed as to the absence of canines,
but disagreed as to the total number of teeth present (viz. 34 or
36) and as to the number of true molars and incisors, the most
commonly accepted formula being i. > c. 4 pm. ee m. a= 34, Many
observers, however, state that there are present at one time 8 cheek-

teeth above, and as they regard the extra tooth as a molar, they
formulate the molars as 3-4 above and 3 below. More rarely we find

the incisors described as being : ; and lastly, two observers” have

described a pair of canines as being present in the upper jaw.

All are agreed as to the number of teeth present in the Jower jaw
of the adult, viz. 9; but there is much disagreement as to the total
number of teeth present in the upper jaw (viz. 8-9), and also as to
the homologies of the individual teeth and sets of teeth.

Most state emphatically that there are no canines present in either
jaw. Cuvier, however, asserted (4) that there was a pair of small
canines present in the upper jaw of the young animal, and he re-
garded them as the accessory teeth of Pallas (25), but this opinion
he afterwards retracted (5).

It remained for Lataste (19) to be the first to show definitely
that there is present in the upper jaw of all young specimens a pair
of small canines; he has shown that these are shed early in life
and that they rarely persist till the completion of the second den-
tition. He bases his conclusions on the shape and position of these
teeth together with the characters of the 2nd maxillary tooth
(ist premolar) as exemplified in a very large series of skulls of all
ages, and finally on a comparison with the teeth of the near allies

of Hyrazx (viz., the Rhinoceros, Tapir, and Horse), which never
possess more than seven cheek-teeth (molars and premolars), while
showing all stages in the development of the canine. He has
succeeded in showing that many of the earlier observers figured and
described these canines, mistaking them for the lst premolars, on
account of the resemblance between the latter in the second dentition
and the milk-canines. But although the lst premolar in the second
dentition is much reduced and has sometimes only one fang, it is
situated some distance from the premaxillo-maxillary suture, and in
the first dentition has a large crushing crown and is two-fanged. He
considers that the canines, together with the 1st premolar, are under-
going suppression, and that as a consequence of this the former teeth
have lost their more typical characters.

With the exception of Giebel (12, 13) and Brandt (2), all observers
state that there is only a single pair of incisors in the upper jaw.
These two authorities, however, bave described in the young animal
a second small and posterior incisor, which is early shed and is
situated in the premaxilla behind the large first milk-incisor. This
tooth is not to be confounded with the milk-incisor No. 1, which is
a large tooth situated between the two permanent ones, as figured by
Cuvier (5)and Blainville (1); it undoubtedly represents a 2nd upper
incisor, although in all probability it is only a milk-tooth, always
present in the fcetus, but seldom, I believe, persistent after birth.
Giebel and Brandt were of opinion that Cuvier mistook these small
incisors for canines ; but as the former are situated in the gum which
covers the premaxilla, while the latter lie well within the maxilla,
their position implies that he did not understand what is generally
supposed to be the fundamental distinction of the canine, viz., that
it is typically a single-fanged pointed tooth implanted in the maxilla
just behind the premaxillo-maxillary suture.

It has been already noted that no observer has seen more than 9
teeth in the upper jaw; none of those who describe the presence of
a canine make the slightest allusion to the presence of 2 upper
incisors, and further perusal of the descriptions alluded to shows
that those who described the 2nd incisor almost certainly were
dealing with Cuvier’s canine. This is probably due to the fact that
the earlier observers do not seem to have had access to some of the
monographs of their predecessors, but it does not excuse a modern
European writer like Lataste having apparently failed to consult a
classical work like Brandt’s Monograph on Hyraa, or a standard
one such as Bronn’s ‘ Thier-Reich.’

Il. Results of the present Investigation.

The material which I have examined was kindly placed at my
disposal by Prof. Howes, and consisted of 5 foetal examples of Hyraz
capensis preserved in spirit, being the specimens the placenta of which
was described by Prof. Huxley before this Society in 1863". The

AU MR. M. F. WOODWARD ON THE [Jan. 5,

specimens measure about 12°5 centim. long and only show a few of
the larger hairs.

The method adopted for the examination of the teeth is, I believe,
the only reliable one (if employed in connexion with serial sections)
by which the true relations of developing teeth in a young animal
can be made out.

The skin was carefully removed from the sides of the jaw, and
the whole jaw, with gum covering it intact, was placed in absolute
alcohol and thoroughly dehydrated ; it was then clarified in clove-oil,
and either examined in that medium or mounted in Canada balsam.
By this treatment the teeth are seen through the bones in their
natural position in relation to one another and to the surrounding
parts, whereas by dissection they are apt to be displaced. Further,
some teeth when undergoing suppression are so minute as to be
practically invisible to the unaided eye, so that under manipulation
by ordinary dissection they would be entirely overlooked. On the
other hand, if exclusively examined in serial sections it is doubtful
if their exact position and relationships could be determined with
absolute accuracy. This is notably the case with the anterior milk-
incisors of the Rabbit (the upper of which measures only *13 millim.
in length) described by Huxley (16) (figs. 4 & 5, di’), and which
were discovered by this method, Huxley being, I believe, the first to
apply it to the examination of tooth relationships.

It is worthy of note that the method does not prevent one after-
wards sectionizing the jaw; in fact, it is best to examine the jaw
first in this way in order to see exactly what teeth are present and
what are their positions, as it then becomes much easier to interpret
the appearances presented by serial sections.

A microscopic examination of the clarified jaw (Plate II. fig. 1)
shows that there are present at this age 8 teeth in the upper jaw and
7 in the lower one.

Those of the upper jaw may be divided into premaxillary and
inaxillary teeth, there being 3 of the former (fig. 1, dz’, di’, di’)
and 5 of the latier (fig. 1, ¢, 1., u1., 111, Iv.). The first pre-
maxillary tooth is very large and roughly conical ; it lies completely
buried in the bone and, from a comparison of a series of skulls, it
becomes evident that it is the milk predecessor of the large permanent
incisor ; it attains a considerable size and persists for a long period after
birth. As the foetus was very young, the permanent incisor had
not yet been differentiated.

The two posterior premaxillary teeth (fig. 1, di’, di*) are very
small, and variable ; both were present in three out of six preparations,
one only was present in two, and both were wanting in the other.

In two cases they were very fully developed (fig. 2, di”, di), although
small, and the anterior one was in all cases the largest. In the speci-
men figured the measurement of the anterior one (di’) is ‘62 millim.
long X ‘35 millim., that of the posterior one (dz’) being *31 millim.
long x °19 millim.

The anterior one presents a small conical crown composed of a
distinct layer of enamel and dentine (fig. 2, di*, c, and d), a well-

1892.] MILK-DENTITION OF PROCAYVIA CAPENSIS. 41

marked cervix, and a simple single fang, slightly constricted at its
base. The smaller posterior one (fig. 2, di”) is much simpler and
not so much calcified, and although it had no distinct fang yet the
pulp-cavity was already partially constricted.

In position the two teeth lie close to the surface of the gum, and
though they overlap the premaxilla they are really external to it,
alveoli being undeveloped *. The anterior one lies just in front of
the premaxillo-maxillary suture (fig. 1, ms.), while the smaller pos-
terior one lies just between the two bones, but under cover of the
premaxilla and quite in front of the maxilla.

In the two cases where only one of these teeth was developed, it was
obvionsly the anterior one from its position ; it was larger and rounder
than the one figured (figs. 1 & 2, di”), and was evidently younger and
still undergoing development.

The maxillary series of teeth are 5 in number: the first (fig. 1, ¢),
a small unealcified tooth-germ, which lies close to the anterior border
of the maxilla, is obviously the canine ; while the four remaining ones
(fig. 1, 1., 11.,111., 1v.) represent the deciduous premolars and have
not yet developed their fangs. They are simple calcified cappings
of the pulp, the only points of interest about them being their
proximity to the premaxillo-maxillary suture and the manner in
which the first one is displaced so as to partially overlie the second.

Examining the teeth of the upper jaw as an entire series, we see
at once that the most fully formed ones are the two small posterior
premaxillary teeth (di*, di®). Unlike the remaining teeth, all of
which lie deep down in the bone, these small ones are situated close
to the surface of the gum, so that they must evidently cut the gum
first if not absorbed.

A tooth whose crown is once calcified does not, as a rule, increase
in transverse diameter, because the dentine composing the greater
part of it is deposited from within outwardly ; so that when dealing
with a tooth possessing well-marked layers of dentine and enamel,
one is fairly safe in saying that the crown will not enlarge much
transversely. When the fang is formed and partially constricted at
its base, one is justified in regarding that tooth as being fully formed,
as the constriction of the pulp-cavity only takes place after the
completion of the tooth.

The small teeth (fig. 2, di’, di*), in possessing the above characters,
may be safely regarded as having attained their full size and being
ready to cut the gum.

We have now to determine the homologies of these teeth. As
we have seen, they are situated in the premaxilla behind the large
incisor and immediately in front of the canine. The only teeth they
can represent are the 2nd and 3rd incisors ; so that the large incisor
is thus proved from its position to be the first or anterior one.
From the earlier development and small size of the 2nd and 3rd

1 Jaeger (JB. nat. Ver. Wiirzb. 1860, xvi.) regards Cuvier’s “ ¢rous incisifs” as
the remainder of a deciduous 2nd incisor ; but as the 2nd incisor very rarely
persists and is generally external to the premaxilla, it is improbable that this
depression, which is fairly constant, can represent its alveolus.

42 MR. M. F WOODWARD ON THE [Jan. 5,

incisors it is highly improbable that they could persist after birth,
whence we may reasonably look upon them as destined to be in all
probability either absorbed or shed in utero.

Giebel and Brandt, as already mentioned, have described two
Mcigors on either side of the upper jaw of young animals, and it
seems, therefore, probable that the 2nd incisor may persist occasion-
ally, especially as in two of my preparations, where only one of these
teeth was present, the second incisor had undergone an increase in
size, although it had not yet developed a fang ; in fact, it was much
more in the condition of the other milk-teeth, being more normally
developed. It will be observed from this that there is nothing which
will justify the unqualified assertion of Giebel and others before
alluded to, that two upper incisors normally exist in the permanent
dentition; for these small teeth never, I believe, persist till the
permanent teeth appear; although they are only represented in one
dentition, I incline to the belief that they should be regarded as
milk-teeth. ;

In the lower jaw (Plate II. fig. 1),in addition to the 2 typical in-
cisors and 4 premolars, we find on either side a small well-developed
tooth (fig. 1, ¢) situated between the incisors and the first premolar.
It lies close to the surface of the gum and is intermediate in size between
the two vestigial upper incisors, measuring ‘4 millim. long x °3
millim. wide, and is correspondingly well developed (fig. 2,c). It
possesses well-marked enamel and dentine layers to the crown and a
small simple fang. Like the small teeth in the upper jaw, its parts
are all fully developed ; but it is so small that, as in the case of the
3rd upper incisor, it has never before been observed. It certainly
never persists after birth, even if it ever cuts the gum at all.

When the jaws are closed, this tooth is situated just between the
upper canine and the third upper incisor, a position which suggests
that it is the lower canine; but it is so close to the lower incisor
that it might very well be the missing tooth of that series.

When, however, we note the order of suppression going on in
the upper jaw, we find that while the two posterior incisors rarely
persist, the canine is occasionally present even in the second dentition ;
this suggests that the latter is not so fully reduced as the incisor,
wherefore we might, by analogy, fairly expect to see the canine more
pronounced in the lower jaw. Further, recent observers’ find in the
Rhinoceros, one of the immediate allies of Hyraz, where only one of
the anterior series of mandibular non-cheek teeth remains, that that
is in all probability the canine and not an incisor.

From argument by analogy, I am therefore inclined to regard
this small disappearing tooth as the lower canine, the 3rd and pos-
terior incisor having apparently completely disappeared.

From the foregoing it may safely be concluded not only that the
canines have, in Hyraz, ceased to have avy functional importance,
but that the incisors are being reduced in number by the suppression
of the posterior ones.

In the permanent dentition the first premolars, both above and

below, are much reduced (though well developed as milk-teeth),
often bearing but a single fang, and are early shed.

It appears to be generally the rule amongst herbivorous animals
that there is a suppression of the anterior teeth of the maxillary
series, often accompanied by a reduction in number of the incisors
and an increase in size of the remaining teeth. From this it would
seem probable that Hyraz, in which the food and habits are very
similar to those of the Rodentia and herbivorous mammals, would
find it more serviceable to possess one or two pairs of large cutting
incisors than three smaller ones ; and the very early development and
large size of the anterior incisors and of the large grinding premolars
becomes readily intelligible upon this hypothesis.

If the jaws of the foetus be examined in relation to the entire
milk-dentition and to the rest of the skull, they will be seen to be
relatively very small. Comparison of a series of skulls shows that
the elongation of the jaws is attained very late, and that above it
mainly involves the premaxillary and anterior maxillary regions.
The conditions are such that in the young animal the jaws are
uncomfortably crowded with teeth; this is especially noticeable in
regard to the position of the first premolars (fig. 1, 1.) and in the ves-
tigial condition of the 2nd and 3rd upper incisors and of both canines.

The clue to the ultimate suppression of the hinder incisors and
the lower canine, and to the vestigial nature of the upper canine and
both first premolars in the second dentition, appears to me to lie
in the consideration of the above facts.

The large size and early development of some of the teeth render
it obvious that these would take up more than their proper share cf
space and nourishment in the already overcrowded jaw, and we
accordingly find that some of the teeth, which were of least
functional importance, become either stunted or entirely crowded
out of the jaw before it elongates.

The premolars of the foetus (fig. 1) extend forwards to the pre-
maxillo-maxillary suture ; and comparison with the adult shows that
the diastemata possessed by the animal are more nearly the result
of a secondary elongation of the jaws themselves than of the mere
suppression of certain teeth.

III. General Considerations.

It will be seen from the foregoing description that Hyrax possesses
several teeth which are only represented in one dentition. The
question then arises whether these are to be considered as belonging
to the lst or to the 2nd series, and the answer to it involves a brief
consideration of the relations existing between the two dentitions in
the class Mammalia.

Prof. Flower (6, 7, 8, 9), in his various contributions to the study
of Mammalian odontology, has all along sought to show that mam-
mals were primitively monophyodont, and that the original single set
of teeth is represented in the permanent (successional) teeth of the
Diphyodonts, the possession of a milk or first dentition being a

44 MR. M. F. WOODWARD ON THE [Jan. 5,

secondarily acquired character, developed comparatively late in the
evolution of the class.

Detailed perusal of his writings shows these conclusions to be
drawn to a large extent from the study of the Marsupialia and
especially of Thylacinus ; the solitary tooth shed by that animal he
regards as the sole representative of the milk or first dentition of its
higher allies (Eutheria), believing the rest of its teeth to represent
the permanent or successional second dentition of the latter. At the
same time (7. p. 2) he has pointed out (and laid great stress on the
fact) that the milk-teeth of the Eutheria invariably show a more
primitive pattern and shape than those of the permanent or second
series which replace them. The latter are often highly specialized :
while the former often (as is especially the case with the Ungulates)
agree more or less closely with the permanent teeth of the extinct
ancestors of the order.

He concludes that when one set of teeth only are present, as in
the Cetacea, it is invariably the permanent or 2nd one, the milk or
Ist set being either not developed or suppressed.

Arguing along the same lines, he considers that when a tooth
such as the Ist premolar in many diphyodont mammals is only present
in one dentition (even though in many cases it is very early lost),
it must belong to the 2nd or permanent series.

Thomas (26, 27) has lately accepted Flower’s views as to the
relation of the two dentitions, and has added largely to our know-
ledge of the dentition of Marsupials, Edentates, and Monotremes.
He shows conclusively that it is invariably the 4th premolar (not
the 3rd as Flower thought) which is replaced by a vertical successor
in the Marsupials, thus bringing the dentition of Marsupials and
Placentals into more complete harmony ; while among the Edentates
he has proved the existence of a milk-dentition in Orycteropus (26).

More recently Kiikenthal (18), in a preliminary account of some
researches on the development of the Cetacean teeth, has sought to
show that, exclusive of the Monotremes, there is no such thing as a
monophyodont mammal. In all Cetacea (the typical monophyodonts)
he finds that rudimentary successional teeth appear in connexion
either with the more fully developed functional ones of the toothed-
whales or with the functionless tooth-points of the Mysticeti. He
argues from this that these supposed typical Monophyodonts are
really modified Diphyodonts, and further that their functional or most
fully developed teeth belong to the Ist or milk-dentition, and not,
as Flower supposed, to the 2ud set. He also advances some reasons
for believing that the homodont condition may be arrived at by a
splitting up of the primitive complex teeth of an original heterodont
type.

In the Marsupials’, from a careful examination of the developing

1 Since the above was written Kikenthal has published (Anat. Anz. 1891,
p- 658) the details of his work on Didelphys, giving figures of the rudimentary
successional teeth in connexion with the incisors, premolars, and even molars,
the last being thus shown in the Marsupials to belong to the Ist dentition.
These observations I can confirm so far as the incisors and molars of Didelphys
are concerned, but in Tvichosurus I can find no trace of the teeth successional
to the molars. This may be owing to the embryo being too young.

teeth of Didelphys, he claims to have found that, besides the succes-
sional tooth to the 4th premolar, there are present indications of the
enamel organs of the successional teeth in connexion with all those
which remain; showing that the adult dentition of the Marsupials,
with the exception of the 4th premolar, corresponds with the Ist or
milk-dentition of the Placentalia, and not, as Flower and Thomas
have held, with the 2nd or permanent one.

From these and other considerations he argues that the two
dentitions among mammals are much more constant than has gene-
rally been supposed, and that they are probably of equal value—
being developed side by side in the jaw from a common enamel
ridge ; and he furtber points out that while the 1st dentition attains
its maximum development in the Marsupials and Cetacea, as we
ascend in the mammalian series it diminishes in importance, so much
so that in many animals (e. g. the Seals) it becomes quite rudimentary,
while in others (. e. Rodents) it possibly disappears altogether.

Should further enquiry substantiate Kiikenthal’s deductions that
all mammals develop representatives of both sets of teeth, the
advisability of retaining the terms Monophyodont and Diphyodont
will have to be considered.

The facts to which I have herein drawn attention (above, pp. 40-42),
taken in conjunction with Kiikenthal’s assertions just alluded to,
show that with regard to teeth present in one dentition only, it is
impossible to say for certain, upon mere examination of the dried
skull, to which set they belong, and even comparative anatomy does
not help us much (as in the case of the Ist premolar of Ungulates).
We must rely entirely upon the study of development, and must base
our determination upon the examination of a series of foetal jaws.

In view of this I am of opinion that we shall sooner or later find
in the rest of the Edentates, the Sirenia, and probably in some
Marsupials, that vestigial milk or rudimentary successional teeth,
which probably never cut the gum, are almost certain to be present
in some form or other—either as calcified structures or simply as
enamel organs.

Should there be found teeth in the foetus showing no signs either
of duplication or replacement by vertical successors, there will be
good reasons for regarding them as belonging to the milk or first
dentition, as this is invariably developed first in time.

From these considerations I should conclude that the vestigial
teeth which I have described in Hyraw (viz., the two posterior upper
_ incisors and the lower canine), together with the upper canine

described by Lataste, which has not been seen to be replaced by
a successional tooth although sometimes persisting with the per-
manent teeth, belong exclusively to the Ist or milk series, which
would then read as follows, viz. :—

IV. The Milk-Dentition of the Rabbit (Lepus cuniculus).

Although the Rabbit is so universally studied in our own labora-
tories and its anatomy is described in detail in so many of our
practical hand-books, not one of the latter rightly deseribes its milk-
dentition, in spite of the fact that all the details concerning it have
been long ago recorded.

If one examines the jaws of a Rabbit from 2-3 weeks old (Plate IT.
fig. 3), one finds on each side of the upper jaw 6 incisors arranged in
two linear series, 3 on each side of the middle line ; the anterior tooth
of each set is known to be the great permaneut front incisor, while the
others have been variously interpreted.

F. Cuvier (3), in the first place, described them as representing
the 2nd and 3rd upper incisors ; his statement has been copied b
several authors (9, 15, 29), who have thus ascribed to the Rabbit at
birth 3 incisors, stating that the outer one is soon lost.

This determination of Cuvier’s was refuted by Owen (23) as long
ago as 1868 and later by Krause (17). These two observers show
that the middle tooth of each series (fig. 3, di”) is in reality the
2nd milk-incisor ; it is a functional tooth for the first three weeks
of the animal’s life, after which time it is shed, being pushed out
by its successor (fig. 3, pz”). The deciduous tooth in the specimen
figured is small and wedge-shaped, its crown being much worn, while
its successor presents a conical unworn extremity, having only just
cut the gum. This latter tooth is the one described by Cuvier as
being the 3rd incisor and by others as being early lost (9, 15, 29).

The probable reason that the 2nd milk-incisor and its successor
are present for some time side by side, after the latter has cut the
gum, may be implied in the fact that the deciduous tooth is as it
were wedged in between the great anterior inciscr and its own
successor and is rather worn away by attrition than shed.

The study of the development of these teeth shows at once that
these two (fig. 3, di”, pi”) are formed from a common enamel organ,
and that they possess the relatiens of a typical tooth of the Ist to
its successor in the 2nd dentition. The fact that the permanent
tooth cuts the gum posteriorly to the milk-tooth, instead of develop-
ing underneath the latter and gradually pushing it out, goes for
nothing, when we consider that the permanent tooth is typically
developed on the inner side of its milk predecessor and not below it.

We see from the above that there are only 2 incisors on each side
of the adult upper jaw, and no examination of even the youngest
foetus in which the teeth are appearing shows us any trace of a
3rd one.

The deciduous premolars of the upper series are 3 in number,
and, as may be seen, they persist until the animal is between 3 and 4
weeks old (not, as stated by Marshall and Hurst (22), being shed
before birth). These teeth have been long known and are figured by
Owen (23); the principal point of interest about them is their
possession of true fangs and their replacement by more specialized
teeth which grow from persistent pulps.

1892.] MILK-DENTITION OF PROCAYIA CAPENSIS. 47

Completing the cheek-teeth above we find at the same age 2 molars
in use, and a 3rd developing one buried up in the maxilla.

The lower teeth at this age call for no special comment ; there are
the characteristic inferior incisors (1 on each side), 2 deciduous
premolars, having the same characters as those of the upper set.
Behind these are 2 molars, the 3rd not having yet cut the gum.

In a footnote to a paper printed in the ‘ Proceedings’ of this
Society, Prof. Huxley (16) in 1880 mentioned that he had discovered
in the foetal Rabbit vestigial milk predecessors to the large upper
and lower incisors, thus making the full milk or 1st dentition to be

i. a pm. This discovery has been generally overlooked by the

writers of works dealing with the Mammalia and the Lagomorpha.

Having examined his preparations and subsequently worked out
this point in a number of feetal Rabbits from the time when the
teeth first appear until birth, I can entirely confirm Huxley’s
statement.

Fig. 4 is a drawing of the clarified jaws of a foetal Rabbit.

At this period there are present 7 teeth in the upper and 5 in the
lower jaw. Of those in the upper jaw the first 3 are incisors, the
large tooth (pi') being the permanent anterior one and the smallest
tooth (di*) being the milk 2nd incisor, the permanent one not being
yet differentiated. The cheek-teeth are 4 in number and represent
the 3 deciduous premolars (d.pm.) and the 1st molar (m’).

In the lower jaw the large incisor (pi,) is well developed, but there
are only 3 cheek-teeth, viz. the two milk premolars (d.pm.) and
the anterior molar (m,). In front of each of the large incisors
(pi', pi,), above and below, is a small tooth (di’, di,}, rather irregular
in appearance, but with its crown composed of typical layers of enamel
and dentine (fig. 5, di’, di,), and possessing all the essential structures
of atooth. In size these teeth are the smallest in the jaws and
measure as follows:—the upper one (di) ‘13 millim. long x -09
wide ; the lower one (di,), which is much larger and varies somewhat,
being 19-34 millim. long and *12-"16 wide.

Examination of young jaws shows that these minute teeth are
among the first to develop, and when they appear they attain with
their enamel organs a relatively large size in proportion to the jaw.
Their growth is early arrested and they remain in a dwarfed con-
dition ; if carefully examined they are seen to present an irregular
contour, and this I regard as expressive of their partial absorption.
They are eventually forced out of the gum, about birth, by the
growing permanent teeth.

These small teeth develop in common enamel organs with the
permanent cutting-incisors, of which they are, as Huxley pointed out,
the milk predecessors. As has been shown, they are uever functional,
and, like the milk-premolar of the Guinea-pig (Cuvier), they are
shed in utero.

The Rabbit, so far as we know, is the only Rodent possessing
milk predecessors to both incisors; while it and the Common Hare
are the only Rodents known to possess deciduous incisors.

48 MR. M. F. WOODWARD ON THE (Jan. 5,

There can be very little doubt that the Duplicidentata, as concerns
their teeth, are the most primitive living Rodents; and as the
deciduous front incisors have almost disappeared in them, we could
hardly expect to find them present in the more modified forms,
where the teeth are reduced in number. It is, however, highly
probable that we might find them in the Hare and possibly in
Lagomys.

‘Krause (17), in describing the deciduous teeth of the Rabbit,
gives the formula i. pm. > which, as I have shown, is the correct

one; but although he gives the correct formula, he cannot have
seen the small deciduous first incisors ; in fact, he says (op. cit. p. 199)
“the four large incisors persist from the beginning” ; so that he
counts the large cutting-incisors twice over, first in the deciduous
and afterwards in the permanent dentition, solely on the grounds
that they happen to be formed very early, when none but milk-
teeth are present in the jaw.

The discovery of these teeth is entirely due to Huxley, but as he
only mentioned it in a passing footnote appended to a paper dealing
with much wider questions, and as he never figured them, I append
ficures, in illustration of my more detailed account of them.

In concluding, I should like to express my thanks to Mr. Oldfield
Thomas for his kind assistance in allowing me access to a fine series
of Hyraa skulls in the British Museum, and to Prof. Howes for his
valuable advice and suggestions during the progress of this work.

5. On the Species of the Hyracoidea.
By Ouprretp Tuomas, F.Z.S.

[Received December 1, 1891.]
(Plate III.)

The present paper is an attempt to work out the species con-
tained in the group Hyracoidea, a group which has of late years
attracted the attention of several prominent systematic workers, but
which, owing partly to its inherent difficulties and partly to want of
material, has remained in a terrible state of chaos. The difficulties
of the subject are indeed so great, owing mainly to the slight differ-
ences and great variability of the species, that in spite of my
material being many-fold greater than that available for any of my
predecessors, I can only feel that my results are quite provisional,
and will need further revision when larger and better series from
more localities are obtained.

The material before me consists of about 120 skins and spirit
specimens, and 122 skulls and skeletons, a number far in excess of
what any previous worker has had. ‘This number is made up,
firstly, of the Museum series (71 skins &c., 67 skulls), which contains
the types of the species described by Gray* in his many papers on
the subject, and the large series of Abyssinian specimens collected
by Mr. W. T. Blanford and used as the basis of his work on the

roup.

Benandlys the fine series (47 skins &c., 48 skulls) belonging
to the Genoa Museum, containing large numbers of the Abyssinian
and Shoan forms and also the only good specimens that I have
seen of the Senegal Hyrax (Procavia latastei). This collection
formed the basis of M. Lataste’s work on the group’*—work only
just begun, and of which only a few preliminary remarks had been
published, but work nevertheless of the highest and most thoughtful
character, so that it has been a great misfortune in this respect
that M. Lataste has had to throw up the Hyracoidea on quitting
Europe for S. America. All his drawings and notes, however, have
been transmitted to me by the Marquis G. Doria, to whom I also
owe the loan of the collection itself, and to whom therefore my
most sincere thanks are due.

Thirdly, four skulls of the Angolan species, including the type
skulls of both P. welwitschii and P. grayi, kindly lent me by Prof.
Barboza du Bocage of the Lisbon Museum, these being the skulls
described and figured by him in his excellent paper on the genus
published in 1889.

Fourthly, two skulls ef P. syriaca lent me by Dr. P. Matschie of
the Berlin Museum, with the permission of Prof. Mobius. I am
also indebted to the former for much assistance in reference to the

type specimens of Hemprich and Ehrenberg’s species preserved in
Berlin.

Fifthly, a skin of the same species lent me by Canon H. B. Tris-
tram of Durham.

It will be seen therefore that not only is the present series unpre-
cedently large in point of numbers, but that it contains the actual
specimens referred to by all the chief writers on the subject of recent
years, viz. Gray, Blanford, Lataste, and Bocage.

Of their papers I would call special attention to that by M. Lataste,
already briefly referred to, on the skulls and dentitions of the different
*‘ subgenera,”’ and especially to his theory that the minute anterior
maxillary tooth of the milk-dentition is a milk-canine which does
not have a successor. This theory I believe to be perfectly correct,
and am most glad to be able independently to confirm Lataste’s
observation. This tooth appears most certainly to be homologous
with the milk-canine of other mammals, even though it is ordinarily
situated some way behind the maxillo-premaxillary suture.

M. Lataste’s other work on the group, being in the form of draw-
ings and rough notes, I have found it very difficult to utilize, espe-
cially as our opinions are naturally very frequently divergent. If,
however, I have published any observation which he has previously
discovered and recorded, I must ask his pardon and plead as an
excuse the very rough character of the notes which he has made:

The excellent paper by Prof. Barboza du Bocage' should also be
referred to, as he has given in it not only full and detailed descrip-
tions of the three Angolan species, in some ways the most interesting,
because the most annectant, of the genus, but he has also given a
complete list of all the known species, with notes on their characters
and localities. This paper has therefore naturally been of much
service to me while going over the same ground.

To pass now to the subject-matter of this paper. In the first
place, it must be admitted that, as pointed out by Lataste, the time-
honoured name of Hyrax? should be superseded by that of Procavia’,
earlier by three years than Hyrax. The family name will therefore
be Procaviide, but the ordinal or subordinal name will remain
Hyracoidea as before, a name of this rank not necessarily being
based on that of a constituent genus, “ Hyrax” might, however,
be adopted as an English vernacular name, the species of Procavia
not having as yet one generally and correctly applicable to them. _

Secondly, there arises the important question as to whether all th
Hyraces should be placed in one genus, or whether “ Heterohyras’
and “Dendrohyraz,’”’ both proposed by Gray and admitted by
Lataste and others, should be recognized as distinct genera or sub-
genera.

Now on this point I find it very difficult to come to a definite
conclusion. Within the group there are two extremes, typified, for
example, by P. abyssinica and P. dorsalis—the former with their

molar teeth very large, hypsodont, and like those of a Rhinoceros in
character, while the latter have small, brachyodont, Palzeotherium-like
teeth ; and these two extremes have been commonly looked upon as
the types of distinct genera, respectively Procavia (= Hyrax) and
Dendrohyrax. But unfortunately there is really almost a perfect
graduation in characters from the one extreme to the other, the chief
link being formed by P. brucei, a species which has been made the
type of a third genus or subgenus, Heterohyraz. Now this Hetero-
hyrax has the essential dental characters of Dendrohyrax combined
with the skull of Procavia ; while the one cranial peculiarity supposed
to be characteristic of it, the early closure of the interparietal
sutures, is not present in P. latastei, a species otherwise in every
respect identical with P. drucei. On the other hand, the perfect
orbits characteristic of Dendrohyraz occur in a form called “D. grayi,”
which, except for this one character, does not differ either cranially
or externally from P. bocagei, and will perhaps prove to be only a
variety of that animal. One single external character, however, dis-
tinguishes the three most typical Dendrohyraces, P. dorsalis, arborea,
and valida, from all the other species in which the point has been
noticed, namely the number of the mamme. These three species
have a mammary formula of 0—1=2, while certainly in P. syriaca,
ruficeps, abyssinica, shoana, welwitschii, and brucei, and therefore,
judging from analogy, probably in P. capensis, pallida, bocagei, and
latastei, there are 1—2=6. The mammary formule of “ Dendro-
hyrax grayi”” and P.emini cannot be forecasted, and therefore par-
ticularly need observation. In any case, however, this character
cannot be used as of generic value, for it separates “ Dendrohyrax’’
equally from both “ Heterohyrax’’ and “ Procavia,” although the
teeth prove that, if anywhere, the division should come between
Heterohyrax aud Procavia. But even then one would not know
into which group to place such an annectant form as P. welwitschii.
Balancing, therefore, these considerations for and against the retention
of Dendrohyrax and Heterohyrax, I have come to the conclusion
that it is better on the whole to recognize only a single genus for the
whole of the Hyraces, which will of course bear the name of Procavia.

Before passing to the actual descriptions of the different species, a
few words are necessary as to the cranial, dental, and external
characters found in the group, as a proper understanding of these is
essential to anyone trying to work out the species of this most
difficult group.

Firstly, it may be noted that, thanks to the work of Lataste already
quoted, and still more to the important paper by Mr. Woodward
just read to the Society (supra, p. 38), the homologies of the
teeth are fortunately quite clear throughout. Especially noteworthy
is the discovery of rudimentary outer milk-incisors, a discovery
which proves the persistent incisors to be really homologous with
the first incisors of normal mammals. Liataste’s determination of
the anterior upper cheek-tooth of the milk-series as me is fully con-
firmed by Woodward, whose discovery of a corresponding lower
milk-canine is of much interest.

1892.] SPECIES OF THE HYRACOIDEA. 53

Owing to the comparative lateness in life at which apparently the
Hyraces become fully adult, and the consequent frequency with which
more or less immature specimens have to be dealt with, special
attention has to be paid to the age of every specimen described.
For purposes of comparison therefore the period of tooth-develop-
ment has been divided into eight stages, mostly determinable by the
relative development of a single tooth, and thus by the comparison
of specimens of similar ages the true inherent differences in size
between different forms become easily definable. A single tooth only
is taken as the main determinant of each of the stages, no account
of the general state of the dentition at any given stage being practi-
cable for all species, owing to the fact, observed by Lataste, that the
time of the fall of the milk-premolars as compared with the develop-
ment of the permanent molars varies in different species.

The following are the stages which I have found divide the
specimens most conveniently into groups of individuals of similar
age. The actual age, in time, at which in the different species
these stages are attained may perhaps be found out later at a more
advanced period of knowledge :-—

Stage I. Before the milk-dentition is fully in place.
II. Milk-dentition all up and in use. m’ not visible.
III. m* up; ™®* below level of bone.
IV. m* just appearing or partly up.
V. m* nearly or quite up ; m° below level of bone.
VI. Tip of m* appearing.
VII. m°® partly or nearly up, but still unworn.
VIII. ™* up and in use.

No doubt Hyraces are practically adult, and are probably breeding,
some time before Stage VIII. is attained, just as in the Kangaroos
and other animals in which there is a horizontal succession of the
teeth owing to the movement forward of the tooth-row, and the
consequent replacement of the crushed and worn-down anterior
teeth by the newly formed posterior ones. Of course the process is
not nearly so highly developed as it is in the Kangaroos, Manatees, and
others; but there is evidently a commencement of this remarkable
provision for the replacement of the worn-out teeth in the Hyracoidea,
especially in the hypsodont species, such as P. capensis, abyssinica, and
their allies.

Thanks to this process, the actual size of the teeth, however
valuable for the discrimination of the species, cannot be defined
satisfactorily by a simple antero-posterior measurement of the tooth-
row or any part of it, for the larger posterior teeth as they push
forwards gradually crush together the whole of the teeth and make
their combined length less and less as time goes on.

To gain an idea of the actual size of the teeth, it has therefore
been found best to take the exact horizontal! breadth of m* at its
broadest point, this tooth being present and available in specimens
at all ages from Stage III. upwards,

54 MR. O. THOMAS ON THE [Jan. 5,

As to the height of the teeth, by which their hypsodontism or
brachyodontism can be gauged, the height of the crown of m* has
been taken as the basis. It is measured, in a tooth as unworn as
possible, from the top of the main anterior cusp* to the bottom of
the valley on the outer side of the cusp ; when there is any trace of
a cingulum it is placed at this point, but when there is not, the
point at which the valley merges into the smooth basal outer surface
of the tooth may always be clearly made out.

The upper incisors of the Hyraces are of two forms, the one sharply
ridged and angular in front, and the other more or less rounded
or even flat anteriorly. This difference, though often incidentally
noticed, never seems to have been referred to sex, of which, however,
I believe it affords a constant index. The study of so large a series
of specimens as the present proves conclusively that all the
specimens with ridged incisors are males, and those with them
rounded are females. It is of the greatest value to have this ready
index to the sex of skulls, as so large a number are either without
skins, or if these exist they are unsexable. It should be noticed,
however, that in certain species, notably P. dorsalis, arborea, and
brucei, the female incisors are also to a certain extent ridged, but to
a degree very slight in comparison with those of the male sex.

Other differences due to sex seem to be few and unimportant.
Even as to size, although male skulls on the whole are rather larger
than female ones, yet individual female skulls often exceed the
great mass of the males. To take an instance, in P. shoana
5 male skulls give the following lengths—89, 90, 91, 92, 93, and 6
females the following—82, 84, 84, 85, 87, 88; but one of the types
of the species, unquestionably a female, has alength of 96 mm., thus
exceeding any of the males as yet recorded. Almost precisely the
same thing occurs in the series of P. capensis, where our largest
specimen is a female. No general rule therefore can be laid down as
to the relative sizes of the two sexes.

Throughout the history of the systematic arrangement of the
Hyraces the interparietal bone has had a large share in causing con-
fusion owing to the alterations that take place in its shape during
life not being allowed for or understood. It was early seen that
different specimens had very differently shaped interparietals, and in
the absence of good series at different ages these differences were
naturally supposed to be of specific value. Thus Hemprich and
Ehrenberg in 1828 laid primary stress on the shape and form of this
bone in separating the four species they recognized; while much
later Gray referred a great deal to it, and the retention of “ Hetero-
hyrax”’ as a subgenus by Lataste practically depended on the age at
which it is united to the other bones of the skull. On the examin-
ation of a large series of specimens, however, it appears that this bone
is by no means really so important as has been supposed for diag-
nostic purposes, and that its differences in shape are really due to

* Not the extreme antero-external cusp, which has no valley on its outer side;
the cusp measured from is nearly always the highest one of the tooth.

1892.] SPECIES OF THE HYRACOIDEA. 55

age, while its fusion or non-fusion with the other bones of the skull,
although generally constant, is a character rather more variable than
has been supposed.

In a young specimen of one of the species in which it is generally
distinct through life, the bone is clearly marked, ordinarily broadly
trigonal in shape, its broad posterior end generally embraced by two
little processes of the supraoccipital, but these vary very much in their
development. At this stage its edges are vertical to the plane of its
surface, or if there is any slanting, it is in such a direction that the
inner cerebral aspect is rather smaller than the outer. This condi-
tion of things remains constant up till somewhere about Stage V.,
when the ever extending temporal muscles begin to encroach in its
vicinity. These muscles seem to induce the development as part of
the parietals of a roughened surface-layer of bone, which, with the
muscles, gradually creeps onwards over the brain-case, and by de-
grees encroaches on and covers up the interparietal bone. The two
parieto-interparietal sutures therefore constantly get closer together,
the interparietal bone naturally appearing narrower and narrower,
and at last the two temporal ridges, which have already met some
time before anteriorly, gradually coalesce further and further back,
and finally block out all trace of the interparietal bone on the upper
surface. Even then, bowever, for along period the bone may remain
uncoalesced, its sutures, in section, describing a curved line following
the increase of the parietal bone over it. This gradual narrowing
upwards of the interparietal may be seen well in the British Museum
skull, No. 69. 10. 24.41, of P. abyssinica, in which, although the
bone itself is broken away, the sutural edge of the parietal clearly
exemplifies the steady extension of their upper layers at the expense
of the smaller bone between them.

Now as to the closing of the parieto-interparietal sutures, the
early obliteration of which is the main character on which the group
“‘ Heterohyrax”’ rests, some words are necessary, as although
really useful in many cases for specific determination, yet the cha-
racter is not one that can be used for breaking the family up into
smaller groups. In the great majority of the species these sutures
are ordinarily persistent and visible, except in so far as they are
covered up in the manner above described. On the other hand, in
P. brucei they close up so soon that in two specimens as young as
Stage III. they have quite disappeared, and in one of Stage II.
they are only faintly visible. But two closely allied species, here
provisionally admitted as such, but really only doubtfully distinguish-
able from P. brucei, have either persistent sutures (P. latastei),
or temporary ones, closing up as the animal gets fully adult
(P. bocagei), thus proving that the character is at most only of
specific importance.

A second character on which much stress has been laid, and one
which has been supposed to be above all suspicion of variability, is
the completion or non-completion of the orbit behind by bone.
This is always accepted as the essential character of the group ‘‘Den-
drohyrax,” and certainly, in the most typical species, P. dorsalis,

56 MR. 0. THOMAS ON THE [Jan. 5,

the orbit is closed, even in the youngest specimens available, down to
Stage I. In P. arborea, however, the South-African form, one
of our four specimens, already fully adult (Stage VIII.), has the
postorbital processes of the frontal and malar separated by at least
2 mm.', the other three having closed orbits. On the other hand,
the type of Dendrohyrax grayi has them completely closed, as has
also a second specimen from the same region ; but I am nevertheless
most strongly inclined to consider these two specimens as only re-
presenting an individual variation of P. bocagei”.

As it appears therefore from both these characters that the Angolan
Hyrax is the one which presents the greatest difficulty, I would
strongly impress on collectors having the opportunity the great
desirability of obtaining more specimens from that country. In
this connection I must again thank Prof. Barboza du Bocage for the
loan of the valuable Angolan specimens preserved in the Lisbon
Museum, a loan which has been of the very greatest service to me.

The development of the anterior lower premolar (p') is worthy of
some notice. In the large-tceothed, hypsodont species, such as P.
capensis, abyssinica, &c., it is a simple slender tooth, with only one
root, and is pushed out by the teeth behind it at a very early age, so
that it is quite unusual to find it present in fully adult animals. On
the other hand, in the small-toothed brachyodont species it is elon-
gated, has two distinct roots, and is practically persistent throughout
life. These differences are.clearly correlated with the amount of the
wear and tear of the teeth and their movement forwards in the jaw,
characters at their maximum in the hypsodont and their minimum
in the brachyodont species.

The predecessor of this tooth (mp') is always long and double-
rooted, showing clearly which of the two adult forms is the primitive
one of the group.

The number of the ribs has also been used as a distinguishing
character of the genera and subgenera, but, so far as I have seen,
all the species examined (including such widely separated species as
P. dorsalis, brucei, and abyssinica) have 21 (rarely 20), while
P. capensis alone has 22. I have, however, thought it worth while
to record the numbers in the specific descriptions wherever I have
direct knowledge of them.

Of the external characters by which the different species may be
determined, the most important are the coloration, shape, and size
of the dorsal spot, a patch of hairs growing on and around the
dorsal gland, and almost invariably of a colour markedly contrasting
with that of the body in general.

The following are the chief variations in the dorsal spot met with
in the different species :—

The central part of the dorsal gland is very commonly quite
naked, notably in P. dorsalis, where the naked part is two or three
inches long, and about half an inch broad. Owing, however, to the
way in which the hairs round the naked part converge towards each
other, this fact is very seldom observable without separating the
hairs, but occasionally in old specimens the naked skin is clearly
visible from above. The distinctions given above between the
different sorts of spots are by no means to be taken aw pied de la
lettre for every specimen examined, many of the groups passing
quite imperceptibly into each other, while in some species the spot
itself varies so much as to be not easily definable.

As to the geographical distribution of the different species the
accompanying sketch-map (see p. 58) will show more clearly than any
amount of description where the different forms are found, and will be
a guide to anyone wishing to know what species may be expected to
occur in any given locality, It may, however, be just noted that while
many places have only one species known from them, most have two,
and that these are almost invariably one of the hypsodont (Procavia)
and one of the brachyodont (Dendrohyraz and Heterohyrax) groups.
Thus in N. Abyssinia we have P. brucei and abyssinica, in Shoa
P. brucei and shoana, in Angola P. bocagei and welwitschii, and in
S. Africa P. arborea and capensis.

The two tables exhibited (see pp. 59, 60) show respectively (1) the
basal lengths’ of considerable series of specimens of each species taken
at as many age-stages as possible, and (2) (a) the breadth of m',
(6) the height of m*, measured as already described, and (c) the hori-
zoutal length of p*. It is to be hoped that, without a more formal
synopsis, which at present I hardly feel capable of drawing up, these
measurements, combined with the rough synopsis of the dorsal
spots just given, will enable anyone to determine specimens without
much difficulty.

Hand-l. Edent. &e. p. 44, pl. xi. fig. 2 (1873) (skull).

Fur of medium length, soft and fine ; neither so long nor so fine
as in P. shoana. Ears short, rounded. General colour dark sepia-
brown, finely speckled with white or pale yellow. Straight upper-
fur hairs dark brown, with a small pale yellow subterminal band ;
underfur along the centre of the back dark smoky grey throughout,
but along the sides, grey basally, and shining silvery yellow distally.
Belly dirty yellow or brownish.

Dorsal spots entirely black, irregularly oval in shape, not so large
as in P. shoana.

Skull? broad, stout and strong; muzzle short; interparietal
sutures always persistent. Diastema short, 8 to 10 mm. Teeth
large and hypsodont, but very variable in size; of the few specimens
with exact localities the eastern ones, from Natal &c., seem to have
smaller teeth than those from the Cape itself. Diameter of m’ 8-0

Hyrax nigricans, Peters, SB. Ges. Fr. 1879, p. 10, belongs here, in which
case the species extends very much further north-west than has been supposed.
The type specimen, however, is too young for certain determination.

(nec Hyrax habessinicus, Hempr. & Ehr.).

Hyrax scioanus, Gig]. Ann. Mus. Genov. (2) vi. p. 21 (1888).

Size very large, form stout and heavy. Mamme 1—2=6. Fur
very long, soft, and fine. General colour grizzled olivaceous grey,
the straight lines of the back brown basally, with a broad dull
yellow subterminal ring and black tip. The greater breadth of the
yellow ring and the larger number of the straight hairs as compared
to the woolly underfur quite take away the appearance of fine
speckling characteristic of P. capensis, and produce a much coarser
mottled appearance. Underfur coloured as in P. capensis, but the
yellow band on both of the sides is broader, and its colour is duller
and more tinged with olivaceous. Belly dirty yellow or brownish.

Dorsal spot very large and diffuse, wholly black, very prominent
in well-marked examples.

Skull large and heavy, but very variable in its proportions, especi-
ally in the length of the muzzle, and consequently in the length of
the diastema. In the female co-type* the latter is fully 14 mm.
long, while in another specimen it is only about 5 mm., but in the
large Genoa Museum series nearly all the intermediate links are
represented. On the whole the skull cannot be definitely distin-
guished from that of P. capensis, although ordinary specimens run
rather larger of the northern than of the southern form. Teeth also
very variable in size: m' from 771 to 8°1 in breadth; crown of m°
about 7°2 or 7°3 high; P* small, single-rooted, about 2°6 or 2:8 in
horizontal length. 22 ribs (in one specimen).

gazzi, and Beccari).

This fine Hyrax, almost if not quite the largest of the genus, has
been the cause of great trouble and uncertainty among writers on
the group ever since Gray first described the specimens obtained by
Capt. Harris at Ankober, these specimens being therefore the co-
types of the species as renamed by Giglioli. Gray’s reference of this

obtained by him in Natal. Lieut. H. Trevelyan has also presented several speci-
mens from Kingwilliamstown.

form to Hemprich and Ehrenberg’s H. habessinicus has been
frequently questioned, and, as will be seen below in the remarks to
that species (p. 66), I have come to the conclusion that it cannot
be supported. The species therefore requires the new name given
it by Giglioli, if it is considered to be distinct from P. capensis, to
which it is most certainly allied. However, although its skull cannot
be with certainty distinguished from that of the Cape animal, yet its
longer softer fur, its more olivaceous colour, its much larger dorsal
spot, and its great difference in locality induce me to consider it as
requiring specific distinction.

The Genoa Museum possesses a large series of this handsome
animal, obtained at many different localities in Shoa by Messrs. An-
tinori, Beccari, and Ragazzi, while there are in the British Museum
the two typical specimens, besides several skulls, collected by Capt.
Harris at Ankober. In addition I refer to this species the two
specimens from the Dalanta plateau spoken of as “ Hyraz sp. nov.”
by Mr. Blanford*, this locality being the most northern recorded
for the present species, and yet considerably south of any place at
which he obtained H. abyssinica (his H. brucei)’.

This species was first described by Bruce in 1790°, but as he
confounded the Abyssinian and Palestine Hyraces, the name syrzaca,
based on his description, has been rejected by some authors on the
ground that his ‘‘ Ashkoko ” is the Abyssinian species and not the
Palestine one. It is, however, quite clear that his main description

was based on a specimen obtained by him on Mount Libanus, and the
name syriaca given by Schreber is evidence as to what country he
considered the home of the species. I am therefore glad to he able
to retain the name by which the species has so long been known.

Thanks to the energy of Dr. A. S. G. Jayakar, of Muscat, I am
enabled to announce a very considerable extension of the known
range of this species, and at the same time of the genus, for he
obtained an adult female with its young at Dofar, on the southern
coast of Arabia, about halfway between Muscat and Aden, no
Hyracoidea having been previously known in Southern Arabia at all.

Aithough agreeing in most of its characters with the typical
P. syriaca of N. Arabia, this Dofar specimen differs so markedly in
the size of its teeth, as also does a Central Arabian one kindly lent
me by the authorities of the Berlin Museum *, that I feel compelled
to consider the southern form as subspecifically distinct from the
northern. I propose to name it in honour of its discoverer
Dr. Jayakar, to whom the British Museum is indebted for examples
of so many members of the Arabian Fauna.

Subspecific diagnoses :-—

A. P. syriaca typica.

Size rather larger; skull broader; teeth markedly larger and
heavier, very hypsodont ; breadth of m' about 7:1 or 7:2 mm.,
height of crown of m* about 7:0. Horizontal length of p' about
2°2 mm.

Hab. The northern half of the whole range of the species.

B. P. syriaca jayakari, subsp. n.

Size rather smaller, and skull narrow ; teeth smaller; breadth of
m’ 6°27 mm.

Hab. South-eastern half of Arabia.—Dofar, S. Arabia (Brit. Mus.,
Dr. Jayakar). Melhan, Central Nejd (Berlin Mus., Coll. Schwein-
Surth).

Judging only from the type-specimen, this southern subspecies
seems to have a rather darker coloration, and less ragged, shaggy
hair, than the typical form, but of course one can lay no stress on
these characters without further specimens for comparison.

also for one of the typical variety from Sinai. In spite of the time that it has
been known, specimens of P. syriaca are by no means common, and the British
Museum possesses only one stuffed specimen without a skull. However,
besides the two Berlin skulls just mentioned, Canon H. B. Tristram has kindly
lent me a skin and skull from Palestine, and there are two Syrian examples in
the Genoa Museum collection, originally obtained by Dr. Lortet.

This species, to which I follow Mr. Blanford in assigning Hyrax
burtoni of. Gray, appears to be essentially a northern desert form of
P. abyssinica, and leads on towards P. syriaca of the other side
of the Red Sea. All these species are very closely allied to one
another, their skulls being practically indistinguishable, and their
distinctions resting mainly on colour. P. ruficeps, however, has
decidedly more pointed ears than the others, at least so far as the
three typical specimens of “ H. burtoni”’ are concerned, but I do
not know how far this is likely to be a constant character. It is
unfortunate that the name ruficeps should stand for this species,
as the rufous on the vertex is far less strongly marked than it is in
many specimens both of P. abyssinica and P. shoana:

1 The use of this name is due to a mistakenideaof Hemprich and Ehrenberg’s
meaning in first founding the species. Their work being written throughout in
Latin, the simple statement of the locality of the animal “ Hyrax ruficeps
(dongalanus)”’ was taken for an alternative name, and then preferred to ruficeps
as more appropriate. No doubt Gray’s misquotation of “ Ayrax ruficeps vel
dongolanus” was the first cause of the mistake. The same remarks, mutatis
mutandis, apply to the use of the word “‘sinaiticus” for H. syriacus by Gray.

2 Now that “Abyssinia” and not ‘“ Habesh” is the form of the name in-
variably used, it seems better to adopt the amended spelling“ abyssinica”
rather than “ habessinica.” Mr. Blanford also comes to the same conclusion ;

Size medium, smaller in var. minor. Mamma 1—2=6. Fur
ordinarily fairly long, at least in the highland specimens, but always
rather coarse and harsh, never long, soft, and fine, as in P. shoana ;
quite short and crisp in the subspecies from the Assab region.
Colour a coarsely-mottled grey-brown, varying towards either olive
or ferruginous ; some specimens marked by rufous over the greater
part of the back. The hairs dark brown at their bases, and black
at their tips, with a broad subterminal band of dirty yellow.

Dorsal spot very small, oval, more inconspicuous than in any other
species, often only to be found after the most minute search, below and
between the ordinary hairs, and sometimes not at all. It consists
simply of a broadening and brightening of the ordinary subterminal
yellow band of the hairs, and when well developed is of a bright
orange-yellow colour. In the great majority of specimens the black
tips to its hairs so hide the yellow that the spot is not visible at all
unless specially searched for.

Skull* stout and strongly built. Muzzle short. Coronal and
parieto-interparietal sutures persistent *. ‘Temporal fossze extending
backwards to within 3 or 4 mm. of the hinder edge of the skull.
Diastema rather constant in its length, generally about 9 mm., but
considerably less in var. minor. Teeth ordinarily very large and heavy
in proportion to the size of the animal, the breadth of m! com-
monly being about 7°4 to 7:9, but in some specimens, which I cannot
otherwise distinguish, they are much smaller and lighter, all the
intermediate links being, however, present. he least breadth
of m' among those before me is 6°7 in the type of “ H. irroratus,
var. luteogaster,” but here the two teeth are considerably worn
down, and probably the true breadth would have been some-
what greater. Height of crown of m> 6-9 or 7 mm. P! very
small, styliform, single-rooted, early deciduous; the horizontal
length ofits crown only about 2 or 2°2mm.__ Ribs ordinarily 21 (but
20 in one specimen and 22 in another).

age. Among the 12 very young skulls with the central suture closed is at least
one taken from a feetus.

Subspecific diagnoses :—
A. P. abyssinica typica.
Size larger. Fur longer. Colour as above described.

B. P. abyssinica minor, subsp. n.

Size smaller (see skull measurements in table). Fur short and
crisp. Colour much as in the typical subspecies, but, owing to the
shortness of the fur, there is an appearance of a greater general
uniformity on the back.

Dorsal spot not more prominent than in var. ¢ypica, its hairs
being equally tipped with black.

Skull small, with a comparatively very short diastema, almost
rivalling that of P. pallida, 6-2 aud 6*5 mm. in the two co-types.
In neither specimen is p! present, so that the tooth is evidently
dropped very early in the present form.

Hab. Alali, between Beilul and Assab, on the west shore of the
Red Sea, about 13° N.

Two specimens of this peculiar little form were obtained from the
above-mentioned locality by Dr. V. Ragazzi for the Genoa Museum.
Both are somewhat immature, being at stage VI.

P. abyssinica minor is interesting, as leading on from the true P.
a. typica towards P. pallida, found still further east in Somali. Both
in size and in its shortened diastema it approaches that species,
although in colour it shows no tendency to the greater paleness of
the back and conspicuousness of the dorsal spot characteristic of
P. pallida.

P. abyssinica, with its variations in colour and size, has always
been and still is the most difficult form to work out of all the family,
and I cannot at all hope to have satisfactorily settled the many
problems which arise in the contemplation of any considerable series
of specimens apparently belonging to it. In the first place, the
original description was founded mainly on a specimen with a black
dorsal spot, a character found in the Shoan species, but not ordi-
narily in the Abyssinian one, but with this specimen there was a
second showing the typical black and yellow spot of the ordinary
Abyssinian form. Now, as Mr. Blanford * states so directly that
“the species identified by Gray with Ehrenberg’s H. abyssinicus*
is a very distinct form,” and geographical considerations point so
strongly in the same direction, I am induced to look upon Ehrenberg’s
black-backed specimen trom Massowa as one of those troublesome
individuals of the present species in which the yellow dorsal spot is
practically absent, and the black tips to the hairs are so developed as
to form a small dorsal black spot*. In any case I feel I cannot
allocate this Massowa specimen *to the Shoan black-backed form

See, for instance, Mr. Blanford’s specimen No. 886 (B.M. 69. 10. 24. 28).
4 Dr. Matschie, of the Berlin Museum, however, is inclined to hold the op-

pa opinion, believing at the same time that the Massowa form is a small
ocal race of the black-backed Shoan one. Should this view be correct, and I am

in the face of the fact that Mr. Blanford thoroughly hunted all the
country between, specially looking out for Hyraces, without finding
any trace of P. shoana until he penetrated as far south as the
Wadela plateau, while the yellow-backed form was exceedingly
common throughout the country from Massowa southwards. The
skulls of the two forms unfortunately give no help in the matter, as
they differ only in size; and although P. shoana ordinarily is far
larger than what I consider as P. abyssinica, yet dwarfed individuals
seem occasionally to occur, in which the skull is scarcely larger than
in the latter species. Still, as a fact, the sizes of the skull and teeth
of Ehrenberg’s type specimens agree closely with those found in the
ordinary Abyssinian form to which I refer them.

6. Procavia PALLipA. (Plate IIT.)
Procavia pallida, Thos. Ann. Mus. Genov. (2) x. p. 908 (1891).

Size small, form stout and squat. Fur very short, close, and
crisp. Colour pale sandy grey, the hairs chocolate-brown basally,
with a broad eream-coloured subterminal ring and a black tip.
Rump rather more rufescent.

Dorsal spot small, oval, pale creamy yellow, the peripheral hairs
with a broader and the central ones with a narrower brown basal
part, but none of them with darker tips. .

Skull (Plate III.) short, broad, and stout, in general appearance
a miniature of the large-toothed Abyssinian forms P. abyssinica and
ruficeps ; coronal and interparietal sutures persistent. Molars very
large in proportion to the size of the animal, and in consequence of
this the diastema is shorter than in any other known species, being
only 5°6 mm. between the alveoli, and 5 between the teeth above,
while in the lower jaw it is practically non-existent, p? almost
touching the outer incisor basally and only distant from it
about 1 mm. terminally. It therefore leaves no room for p', oc-
casionally present in other species, M' 6-9 mm. broad in the type ;
m* with a high crown, but, as it is somewhat worn, I can only say
that it is more than 5°4 mm. high, that being its present height.
P' gone in the type; no doubt small and early deciduous.

Hab. N. Somali-land.

Type in British Museum (85. 11. 16. 4).

This peculiar little species bears, within the typical Procavia
with open interparietal sutures and large teeth, very much the same
relation to P. abyssinica that P. brucei somalica does in the ‘‘ Hetero-
hyrax” group to P. 6. typica, the geographical relations of each pair

by no means positive about the opinion advocated in the text, the name of the
Massowa Hyrax would be P. adyssinica typica, of the Shoan one P. abyssinica
shoana, and of the ordinary N. Abyssinian one with yellow dorsal spot P. alpini,
Gray. In this connection I must again express my sincere thanks to Dr.
Matschie for the patience and kindness with which he has borne the brunt of
question after question about this unfortunate type of Hemprich and Ehren-
berg’s, a specimen which, in spite of all, must still remain a stumbling-block for
naturalists until it is supplemented by a proper series of fresh examples col-
lected exactly at the same place. ie

being just the same. Its differentiation has, however, proceeded so
much further that I have had little hesitation in erecting it into a
distinct species, even though P. abyssinica minor approaches it in
some respects. The type is a fully adult female obtained on the
25th of December, 1884, by the well-known collector Herr J.
Menges, on the Hekebo plateau, N. Somali-Jand.

It is much to be hoped that further specimens of this little species
will be soon obtained, so that we may gain an idea of its variation
and geographical distribution.

Cat. p. 286 (1869); Bocage, J. Sci. Lisb. (2) iii. p. 186 (1889).

Size medium. Mamme 1—2=6. Fur short, very coarse and
hispid, quite unlike that of any other species. General colour of
back coarsely grizzled sandy brown, the hairs dark blackish brown
for five-sixths of their length, dull yellow terminally or subtermin-
ally, the tips, however, more rufous on the face and along the centre
of the back; the brown bases of the hairs showing through and
materially darkening the general colour.

Dorsal spot, in the single specimen available, rather elongate, al-
though not so much so as in P. brucei and its allies. Its hairs dull
pale yellow throughout.

Skull* stout and strong; muzzle short ; frontal region unusually
broad, the ledges overhanging the orbits, more developed than in
other species; interparietal sutures persistent; diastema short,
about 8 mm. in each of the two specimens before me; temporal
fossee extending backwards quite to the occipital ridges. Teeth
rather small, breadth of m* 6°4 and 6°5 in two skulls; height of
crown of m® 5:2; pl elongated, two-rooted, more as in the Hetero-
hyrax and Dendrohyrax groups, its crown 41 mm. long horizontally.

Hab. Angola, coast-region (Bocage).

The only specimens of this rare species that I have been able to
examine are the skull of Dr. Welwitsch’s original type, most kindly
lent me by Prof. B. du Bocage, and a skin with its skull received in
1888 by the British Museum from the Lisbon Museum. Both
these specimens have been examined and the typical skull figured
by Prof. Bocage, so that I have no material by which to supplement
the excellent description he has there given to the species.

The true position of P. welwitschii in the genus is somewhat
doubtful, as its skull agrees best with those of P. syriaca, abyssinica,
&c., its elongated dorsal spot and rather small teeth but long pt
approach those of P. brucei and bocagei, while the peculiar quality
of its fur separates it from any other species.

Dealing only with the Angolan species, Prof. Bocage has taken it
as a type of the Procavia group ; but I consider that if anything it is
further from P. capensis and abyssinica than it is from P. brucei and

1 Good figure: Bocage, ¢. c. pl. i. fig. 1.

bocaget. _ More specimens, however, to show its variability and
geographical distribution will be needed before its true relationship
can be cleared up.

8. PRocCAVIA LATASTEI, sp. 0.

Fur close, soft and fine. General colour soft fawn-grey, more
pallid than in P. brucei. A large patch on the side of the neck
pale yellowish white, the hairs pale at their bases; this patch is
not, however, conspicuous amid the general pallor.

Dorsal spot narrow, elongate, clear pale yellow to the bases of the
hairs ; in fact, just as in P. brucei and bocagei.

Skull in general form much as in P. brucei, except that it appears
to be rather broader and more stoutly made. Muzzle short and
conical. Interparietal and coronal sutures persistent. Diastema
long, 10 to 12mm. Teeth small, but proportionally rather larger
than in P. érucei. Breadth of m 6 to 65 mm. Pp! small, but
two-rooted, 3 or 3:1 long.

Co-types nos. 55-3238 (skin) and 2684 (skull) of the Genoa
Museum (coll. Lataste).

Hab. Senegal.

M. Lataste obtained several specimens at Félou and Medine,
Upper Senegal, and there is a young one in the British Museum
received in 1844 from the dealer Parzudaki, and referred to “ H.
burtoni” by Gray (Cat. Carn. &c. p. 285).

From M. Lataste’s notes and drawings I gather that he referred
his Senegal specimens to P. bocagei, a reference by no means very
wrong, as they are unquestionably closely allied to that form.
I am, however, induced to separate them, at least for the present,
by the fact that the whole of his specimens, 7 in number, besides an
eighth, fully adult, of which he gives a drawing, have their inter-
parietal sutures persistent, thus differing from P. docagei, in which
the sutures are all closed by about stage IV. or V.

The close alliance of this species to “ Heterohyrax”’ brucei in
general characters, while it has the open sutures of Procavia s.s., is
a striking proof of the necessity for abolishing Heterohyram as a
separate genus.

It is with great pleasure that I attach to this species the name of
the distinguished author of the paper ‘‘ Sur le systéme dentaire du
genre Daman”', who collected the specimens himself, and after
whom it is particularly suitable that a member of this interesting
genus should be named.

grizzled grey, very much as in P. drucet. Posterior back not tinged
with rufous. Belly white or yellowish. ,

Dorsal spot inconspicuous, nearly hidden by the surrourding hairs,
but on separating these it is seen to be well-developed, elongate, its
hairs white or pale yellow to their bases.

Skull* light and slender, with a narrow elongated muzzle and
flattened frontal region. Parietal, interparietal, and coronal sutures
closing at about stage V., always closed in adult animals. Diastema
long, about 13 mm. in adults.

Teeth small and delicate, markedly brachyodont ; breadth of m*
5°6 to 6°4; height of crown of ™* about 4°5. Pp! elongate, two-
rooted, long, persistent, its crown about 3°7 or 3°9 mm. long.

Type in British Museum (68. 12. 19. 3).

Hab. Angola (‘région moyenne, et les hauts plateaux,” Bocage).

The retention of this species as distinct from P. brucei rests on
very much the same, rather slender, foundation that the separation
from it of P. latastei does, namely the age at which the interparietal
sutures ordinarily close. This seems to take place in P. brucei at -
about stage I1., in P. bocagei at stage V., and in P. latastei never, or
at least not until fully adult life is reached. The longer and slen-
derer muzzle of P. bocaget and its more developed p' may also serve
to distinguish it from both, which then, the intermediate link being
gone, seem more than ever distinct by their interparietal characters.

Two specimens, male and female, sent in spirit by E. Lort Phillips,
Esq., from Berbera (the female the type of the subspecies); and a
skin (9) from Gerbatir, N. Somali-land, by J. Menges.

This species has been peculiarly unfortunate in the large number
of names that have been applied to it, and still more in the frequency
with which its proper name has been applied to other species. The
chief cause of the confusion has been the fact that the skull of the
type has never been extracted until now, and that on this account
the common large-toothed N. Abyssinian species (P. abyssinica) was,
without much close examination, dubbed with its name.

On extracting, however, the skull of the specimen in the Museum
collected by Dr. Riippell, and specially mentioned as the type by
Gray, it is found to belong without question to the small-toothed
species, which must therefore bear the name of P. brucei. To this
species also belongs the ‘‘ aberrant specimen of H. brucei” (No.
786) referred to by Blanford (Zool. Abyss. p. 254, 1870), aberrant
really only in so far as it differs from the large-toothed form, to
which, naturally following the founder of the name, he wrongly
applied the designation P. brucei. The fact of the skull of this

specimen being crushed, as mentioned by him, sufficiently accounts
for his not realizing that the animal belonged to quite a different
species from the rest of his specimens.

P. brucei is the most widely distributed of all the Hyraces,
extending from Senaté, N. Tigre, its most northern recorded locality in
Abyssinia, straight southwards as far as Mozambique, while its
subspecies extends eastwards into Somali-land.

The typical race of P. brucei seems to be a highland form, as Mr.
Blanford’s specimens were taken at 7500 feet and 8000 feet in
Abyssinia; the inland examples come from the great lake plateau,
and Mr. Wray’s Taita one was taken in the mountains at an altitude
of 4500 feet. On the other hand, Mr. Lort Phillips tells me that
var. somalica occurs at an altitude of three or four hundred feet
only, about 20 or 30 miles inland of Berbera.

In Abyssinia P. brucei seems to be far rarer than the two large-
toothed species occurring with it, P. abyssinica in the north and
P. shoana in South Abyssinia and Shoa; as both Mr. Blanford
from the former and the Italian collectors from the latter each
obtained only two or three specimens of this species as compared with
some twenty or more of its rivals. This is of course only what one
might expect, judging from the lesser specialization of its teeth,
which presumably put it at a disadvantage compared with its hypso-
dont competitors.

[PROCAVIA GRAYI.

Dendrohyrax grayi, Bocage, J. Sci. Lisb. (2) iii. p. 190 (1889).

External characters as in P. bocaget. Mammary formula unknown.
Skull and teeth also as in that species, except that the orbits are
completed behind by bone.

Type in the Lisbon Museum,

Hab. Angola; Quissange, Capangombe (Anchieta).

Basing his allocation on the presumably important character of
the completed orbits, Prof. du Bocage assigned the only specimen
of this form of which he had seen the skull to Dendrohyraz, and
then naturally distinguished it from “ D.” arborea and dorsalis; but
I am much more disposed to consider it as an abnormal variation of
P. bocagei for the reasons set forth below. In fact I give it a
separate heading chiefly to stimulate inquiry, so that the point may
be later settled with certainty. Its position, if a good species,
would be here between the brucei group and the more typical
Dendrohyraces.

To begin with, I am a disbeliever in species only distinguishable
by a single character of nearly or quite generic rank, and believe that
if P. grayi really were a distinct species of a different group there
would be some other characters besides the completed orbits that
would betray the fact to an eye so trained as that of the describer
himself. As a matter of fact, however, the British Museum received
from Prof. du Bocage in 1888, under the name of “ H. bocagei,”
a skin (88. 12. 6. 1) which, when its skull was extracted, proved to
have completed orbits, and therefore to be a “ P. grayi.’ No

1892.] SPECIES OF THE HYRACOIDEA. 73

better proof could be needed of the close external resemblance which
P. grayi bears to P. bocagei. But this specimen is of further interest,
for while it has the completed orbits of P. grayi, it has the closed
coronal sutures ordinarily characteristic of adult P. bocagei; while
the type of P. grayi, most kindly lent me for comparison by Prof. du
Bocage, has at stage V. the coronal and the parieto-interparietal
suture of the right side still open, the left one was closed. This
closure at stage V. is very characteristic of P. bocagei; but, had it
not been for the second specimen, one might have been doubtful
whether the coronal suture was destined to close in P. grayi.

While leaving the question still open, however, I may point out
that one external character, when observed, will really settle it. If
a P. grayi is found with only 0—1=2 mamme, it will be a Dendro-
hyrax and a distinct species ; but if, as I expect, it has |—2=6, as in
P. brucei, &e., there will be no longer any reason for keeping it sepa-
rate from P. bocagei*. Both the examples before me are males,
and therefore the discovery of its mammary formula must wait until
more specimens are collected. |

Not having received any further examples of this remarkable
species, I can only reproduce the salient points of my original dia-
gnosis, which is based on a young specimen still only at stage I.

Fur very long, soft, and fluffy. General colour pale yellowish
white, not unlike the belly colour of P. arborea. Hairs above brown
for their basal, and pale yellow for their terminal halves. Belly hairs
white to their roots.

Dorsal spot white, the hairs white throughout.

Skull about the same size and shape as that of a P. dorsalis of
the same age, markedly narrower and more elongated than that of
similarly aged specimens of P. shoana. Orbit not closed posteriorly.
Interparietal sutures open.

Teeth not distinguishable at this early age from those of P. dorsalis,
except that mp’ is decidedly narrower. Breadth of mp* 5-6 mm.;
height of its crown 4°1 2.

Hab. Monbuttu, Central Africa (Dr. Emin Pasha).

I am unable to give further particulars about this animal, owing
to the want of adult specimens, but an increased knowledge of the
group in general only convinces me more of its distinctness from any
other species. In one respect it is especially interesting as showing
a general relationship to Dendrohyraz, while it has not the one par-
ticular cranial character supposed to be distinctive of that group,
the completed orbit.

1 The mammary formula of P. bocagei itself is not as yet absolutely known,
but I have little doubt that it is the same as that of its close ally P. brucet.

? By mistake the dimensions of this tooth were given in 1888 as those of
m!; but the specimen is younger than I then realized, and m! has not yet been
developed.

This species is of course that referred to by me with much doubt
as “ Hyrax brucei, Gray (?),” when working out the collections of
Mr. H. H. Johnston from Kilima-njaro. As the skins had no
skulls with them, and I did not then know how much reliance might
be placed on the peculiarities of the coloration, I naturally referred
them to a previously known species, rather than run the risk of
describing them unnecessarily.

P. dorsalis is one of the few species of the group that is quite
distinct from all its neighbours, and presents therefore but little
difficulty as to its determination. Its long shaggy fur, peculiar
coloration, and proportionately large head and small body distinguish
it at once from allitsallies. Dr. Jentink’s Hyraw stampflii presented
a remarkable degree of variation in the shape of its lower jaw, and
in other characters—variations so great that without a very large
sereis of specimens he naturally considered them to be of specific
value. Other specimens, however, since obtained both in Liberia and
elsewhere prove the essential identity of H. stampflit with dorsalis.

W. T. Blanford, Esq., F.R.S., F.Z.S., in the Chair.

The Secretary read the following report on the additions to the
Society’s Menagerie during the month of January 1892 :-—

The tctal number of registered additions to the Society’s Mena-
gerie during the month of January 1892 was 56, of which 29 were
acquired by presentation, 7 by birth, 6 by purchase, 8 were received
in exchange, and 6 on deposit. The total number of departures during
the same period, by death and removals, was 71.

Mr. W. Bateson, F.Z.S., exhibited some Crab’s limbs bearing
supernumerary claws. It was shown that these extra parts are
really a complementary (right and left) pair of indices or pollices,
according to their position of origin, and not repetitions of the two
pincers of the claw, as was commonly stated.

A letter was read from Prof. R. Ramsay Wright, F.Z.S., of
the University of Toronto, enclosing and calling attention to some
phctographs of the heaps of skulls of the American Bison (Bison
americanus), which are commonly collected on the plains of the
Saskatchewan, and are piled up on the sidings of the Canadian
Pacific Railway awaiting transport, and which testify to the enormous
number of these animals recently exterminated in this district.

Mr. Sclater laid on the table two specimens, in spirit, of chicks
of the Partridge Bronze-wing Pigeon (Geophaps scripta) which had
been hatched in the Society’s Gardens on the 7th of June last ; also
an egg of the same species of bird, laid in the Gardens, and made
the following remarks :—

I cannot at all agree with Dr. Bowdler Sharpe in his recent
proposal to divide the very natural order “Columbz” into two
portions, and to associate the Geophabes or Ground-Pigeons with
the Gallinaceous birds *.

According to the observations we have made from time to time in

1 See ‘Review of Recent Attempts to Classify Birds,’ pp. 69, 70.—N.B. The
correct plural of Geophaps is Geophates, from oa, gen. papds.

the Society’s Gardens, where several species of the Ground-Pigeons *
have bred repeatedly, the young of the Ground-Pigeons when
hatched are nearly naked and quite helpless, and differ in no respect
from the young of the typical Columbz. In proof of this I exhibit
two specimens of the young of the Partridge Bronze-wing Pigeon
(Geophaps scripta), hatched in the Gardens on June 7th last, and
about 14 days old when they died. It will be observed that at this
date they were barely covered with feathers and hardly fledged.
In fact one of them was actually killed by falling from a slight
elevation in the Aviary, having been hatched in the nest of a Barbary
Turtledove (Turtur risorius), to which the egg had been removed
in consequence of the bird that laid it refusing to sit upon it. It
cannot therefore be said that these birds are ‘‘able to run soon
after birth.” Nor, in the reference given by Dr. Sharpe, does
Mr. Gilbert, so far as I can gather from his remarks, say so; he
merely states that ‘‘the young bird on emerging from the egg is
clothed with down like the young of the Quail” (Gould’s ‘ Hand-
book to the Birds of Australia,’ vol. ii. p. 134). I cannot therefore
allow that on this ground there is any justification for the important
step that Dr. Sharpe proposes to take.

As regards the other point put forward by Dr. Sharpe in justi-
fication of his proposal, it is no doubt the fact that the sternum of
the Australian Ground-Pigeons is longer and narrower than the
corresponding organ in the typical Columba. But the general
characters of the sternum in Geophaps and its allies remain the same
as in the typical Columbz, so that on this point also I see no
sufficient ground for the alteration proposed.

I prefer to keep all the Columbz together, as heretofore, in one
group of ordinal value, as constituting a very well-defined and very
natural division of the class of Birds, and I even doubt whether more
than one family can be properly made of them.

Among a series of Tertiary Vertebrate fossils recently acquired by
the British Museum my attention was specially directed to one
labelled by the dealer from whom it was received, ‘* Sirene, Oligo-
caen, Monte Grumi, Vicenza.” At the first glance I felt convinced
that the assignation of the specimen to the Sirenia was correct ; but,
at the same time, one of the two teeth contained in the specimen
struck me as presenting a peculiarity of form such as I had never
seen in any other Sirenian. Further examination led me to the
conclusion that the specimen had an important bearing on the

unsolved problem of the evolution of the Sirenian order, and that it
was accordingly worthy of being brought under the notice of this
Society.

Before proceeding to the description of the specimen a few words
are necessary as to the Sirenian remains hitherto recorded from the
Venetian Tertiaries. Some years ago the late Baron Zigno' described
and figured a certain number of Sirenian remains from the Miocene cf
Belluno, in the north of Venice, which were referred to four species,
under the names of Halitherium bellunense, H. angustifrons, H.
curvidens, and H. veronense. At a later period these four species
were reduced by Professor Lepsius*, of Darmstadt, to two; H.
bellunense being transferred to Metaxytherium, while H. angusti-
rons and H. curvidens were merged in H. veronense. Since to my
mind the distinction between Metaxytherium and Halitherium is not
of sufficient importance to be regarded as a generic one, we may,
so far as this information goes, reckon the Venetian Sirenians as
indicating two species of Halitherium, under the names of H. bellu-
nense and HH. veronense.

Vicenza, where the specimen under consideration was obtained,
is situated, I need hardly say, in the south-western half of the
Province of Venice, a little north of the parallel connecting Verona
and the city of Venice. In spite, however, of its distance from
Belluno, it is most probable that the mammaliferous beds of both
localities are of the same horizon; in which case those of Belluno
should be reckoned as Upper Oligocene.

Of the Sirenians from Venetia the types of Halitheriwm bellunense
and H. veronense exhibit the cheek-teeth in a good state of pre-
servation. In the latter species * the upper premolars are very small
teeth, with nearly cylindrical crowns. On the other hand, the upper
molars are relatively large teeth, with oblong crowns, carrying two
transverse ridges, with fore-and-aft talons. The anterior talon in
these teeth is very large and prominent, while the posterior one is
considerably smaller. Their first transverse ridge is more nearly
continuous than the second. When somewhat worn, as is the case
with those of the type specimen, these transverse ridges show nearly
straight bands of denitine, and not the distinct trefoils observable in
the molars of Halitherium schinzi from the Oligocene of Hessen-
Darmstadt. A distinct tubercle occurs in the inner half of the
median transverse valley of these teeth. In Baron Zigno’s figures
there is no indication of what I shall allude to as a masked sele-
nodont structure in these molars. :

Coming now to the consideration of the specimen forming the
subject of this communication, of which a representation of the teeth
is given herewith (see fig. 1, p. 79), it nay be observed, in the first
place, that it is a fragment of the left maxilla of a very young mammal
of comparatively large size. It shows part of the palatal surface, the

external wall, the anterior root of the zygomatic arch, a portion of
the floor of the orbit, and the aperture of the canal for the fifth
nerve. At the hinder extremity of the palatal surface are preserved
two molariform teeth, which are almost or quite untouched by wear,
and are, fortunately, uninjured. By filing away the alveolar parapet
in front of the anterior one of these teeth, there have been revealed
the two roots of a third tooth. Behind the last remaining tooth
there is a portion of the alveolus of a fourth tooth which had
evidently not been protruded from the gum.

Now the unworn condition of the two remaining teeth and their

position with regard to the anterior root of the zygomatic arch,
coupled with the alveolus of the unprotruded fourth tooth, clearly
indicate that the jaw belonged to an exceedingly young animal.
And, apart from their structure, we should further be justified in
regarding the two entire teeth as belonging to the deciduous series if
their owner were a diphyodont mammal, or to the premolar series if
the animal were monophyodont. ‘I'here are, however, considerations
which enable us to determine the serial homelogy of the teeth more
definitely.

Each of the two teeth carries on its crown well-marked but dis-
continuous transverse ridges, separated by deep valleys. In the
hinder tooth the crown is oblong and nearly symmetrical, and carries

80 MR. R. LYDEKKER ON A SIRENIAN JAW [Feb. 2,

two such ridges ; while in front it has a long and prominent talon,
and behind a shorter one, which runs upwards to join the inner
extremity of the second transverse ridge. In the inner half of the
transverse median valley there is a small double tubercle. I shall
have more to say on the structure of the ridges of this tooth by-
and-by.

The anterior one of the two teeth differs from the other in being
much more elongated, and in narrowing gradually from back to front,
where it terminates in a blunt point. It has, moreover, three,
instead of two, transverse ridges; the second and third ridges
corresponding closely in structure with the two ridges of the hinder
tooth, while the first ridge is more irregular in shape, and has on its
anterior surface a rudiment of the anterior talon of the hinder tooth.

Reverting to the latter, an examination shows that the transverse
ridges are not simple continuous ones, but are formed by an inner
and outer column, closely pressed together ; the whole four columns
corresponding to those of an ordinary bunodont molar, like that ofa
Pig, and representing the proto-, para-, meta-, and hypocone of Pro-
fessor Osborn’s system of notation of these dental elements. A
further examination will, moreover, show that these four columns are
not of a bunodont type, but are modelled on a peculiar modification
of the selenodont structure.

In order to illustrate this I have had figured a left upper molar
(fig. 2, p. 79) of the extinct Siwalik genus Merycopotamus, which
is a specialized representative of the Artiodactyle Ungulate family
Anthracotheriide. It will be apparent from that figure that the
external surfaces of the outer columns (paracone and metacone),
instead of being nearly upright, are inclined very much towards the
centre of the tooth, so that the summits of these columns are squeezed
into the crescents formed by the inner columns (protocone and
hypocone). It will further be observed that the external surfaces
of the paracone and metacone of the Merycopotamus-molar carry a
median ridge (c) flanked by two lateral ridges (a, 4).

Now if the metacone of the hinder tooth in our specimen be com-
pared with that of the Merycopotamus-molar, there cannot be any
hesitation in recognizing their close similarity in structure—the
external surfaces of the outer columns showing the same inclination
towards the centre of the crown and having the same general contour.
In the present specimen, however, the metacone has assumed a more
oblique position to the axis of the crown, and has been squeezed
right into the heart of the crescent of the hypocone. In consequence
of this the postero-external ridge of the metacone has been lost, and
its central and anterior points have come into line with the central
cusp of the hypocone to form the imperfect transverse ridge of the
molar. A precisely analogous condition obtains with regard to the
paracone and protocone’.

It appears, therefore, to be quite evident that the hinder tooth of
the specimen under consideration is constructed on an extreme and

1 Although these points are apparent enough when the actual specimens are
compared, it seems to be impossible to indicate them clearly in a figure.

1892. | FROM THE OLIGOCENE OF ITALY. 81

apparently degenerate modification of the brachydont selenodont
molars of certain extinct Artiodactyle Ungulates.

We may, however, go a step further than this. It is, I believe,
an attribute of all Artiodactyle Ungulates, whether their cheek-teeth
be of the bunodont or of the selenodont type, that while the last
upper deciduous or milk-molar resembles the permanent molars in
form, the penultimate milk-molar is an elongated tooth of a more
complex type than either the last milk-molar or the two succeeding
permanent molars. In the adult dentition, on the other hand, the
last upper premolar of Artiodactyles is nearly always simpler than
the first molar, and in none is it more complex or longer.

Now the two teeth of the specimen under consideration present
precisely the same structural relationship to one another as is pre-
sented by the penultimate and last (third and fourth) upper milk-
molars of Artiodactyles. I take it, therefore, not only that these
teeth are third and fourth upper milk-molars, but likewise that they
belonged to an animal showing decided indications of Artiodactyle
affinities—these affinities being with an Artiodactyle that had
assumed selenodont molars more or less closely approaching the
Merycopotamus type.

This being so, the question arises whether the specimen under
consideration may not have belonged to an actual Artiodactyle. To
this it may be replied that, so far as I am aware, no Artiodactyle has
hitherto been described possessing molar teeth of the type under
consideration ; so that if the specimen were really Artiodactylate, it
would indicate an entirely new form.

Apart, however, from this, the structure of the second tooth in
the specimen presents such a marked Sirenian facies that, as I have
said, one is prompted to at once refer the specimen to that group of
mammals. If, moreover, it be compared with Baron Zigno’s figure
of the upper molars of Halitherium veronense, it will be seen that
the last milk-molar of the present specimen accords in almost all
respects with these teeth. Both have two interrupted transverse
ridges, with a large anterior and a small posterior talon; and in
both there is a tubercle a little to the inner side of the middle of the
transverse valley. Moreover, both teeth agree in the shape of the
crown; while the excess in the size of the teeth of Baron Zigno’s
specimen over those of the one under consideration is precisely such
as we should expect to find between the milk and permanent molars
of one and the same animal. It is true, indeed, that in Zigno’s
figure what I may call the masked selenodontism of the teeth under
consideration is not apparent. This may, however, be due to the
circumstance that the teeth of the type of H. veronense are con-
siderably worn ; while it may also be in part owing to the difficulty
-of expressing such features in a lithograph. Moreover, there is the
possibility that the masked selenodontism of the milk-molars may
not have been retained in the permanent dentition.

In regard to the existence of a deciduous dentition in the Sirenia,
it is already known that milk-molars and premolars were developed
in Halitherium schinzi. It is, however, probable that in that species

Proc. Zoou. Soc.—1892, No. VI. 6

82 MR. R. LYDEKKER ON A SIRENIAN JAW. [Feb. 2,

the milk-molars were not like those of the present specimen, since
the permanent molars were of a more Hippopotamus-like structure
than are those of H. veronense, and show no indications whatever of
selenodontism.

Conclusive evidence of the Sirenian nature of our fossil is, however,
afforded by the orbital region, which is almost exactly the same as
in the Sirenian from Jamaica described by Sir R. Owen’ as Pro-
rastomus sirenoides. In both we have the same peculiar eversion
and projection of the lower border of the orbit which is absolutely
characteristic of the Sirenia. In both, again, we notice the extra-
ordinary size of the foramen for the exit of the fifth nerve, and its
immediate proximity to the anterior border of the orbit, these
being also distinctive Sirenian features.

Then, again, a comparison of the last milk-molar with the upper
molars of Halitherium schinzi (e.g. B.M. No. 40859) clearly shows
the ordinal identity of the two forms.

I take it, therefore, that the Sirenian nature of the Vicenza
Specimen is certain; and since its milk-molars agree in general
structure and relative size with the permanent molars of Halitherium
veronense, Which occurs in the same country and probably on the
same geological horizon, the evidence appears to be very strongly in
favour of the reference of the specimen in question to that animal.

Apart, however, from any question of specific reference, the
specimen before us undoubtedly throws a flood of light on the origin
of the Sirenia, and points clearly to their derivation from an ancestor
belonging to an Artiodactyle Ungulate with short-crowned and
selenodont molar teeth. It is, indeed, no new idea that the Sirenians
show Ungulate affinities, this presumed origin having been very
strongly urged by many zoologists; although Professor Flower,
writing in the article “Manatee’’ in the ‘ Encylopedia Britan-
nica,’ expresses his opinion that the few facts at present known
relating to the ancestry of the Sirenians “lend no countenance to
their association with the Cetacea, and on the other hand their
supposed affinity with the Ungulata, so much favoured by modern
zoologists, receives no very material support from them.” If,
however, my interpretation of the affinities of the present specimen -
be accepted, it will go a very long way towards solving the problem
of the Sirenian genealogy.

So far as I am aware, the component elements of the molar teeth
of the Sirenians have not hitherto been homologized with those of
mere typical teeth. The molars of the present specimen clearly show
us, however, the homology of the elements of the simple and con-
tinuous transverse ridges found in Manatus and Halitherium schinzi,
such ridges being clearly only one step more in the degeneration from
a selenodont type exhibited in the molars of the specimen before us.

I may add that although the upper permanent molars of H. ver-
onense differ considerably from those of more typical species of
Halitherium, while there is no evidence that the latter had milk-
molars of the type of the present specimen, yet I should not on

e
these grounds be disposed to.regard the former as the representative
of a distinct genus.

I find, however, by a comparison of Baron Zigno’s figures with
skulls of Halitherium schinzi and Prorastomus sirenoides, that the
skull of Halitherium veronense differs altogether from the former
and agrees with the latter. This is shown in its long and narrow
contour, narrow and elliptical narial aperture, slight deflection of
the rostrum, and the form of the inferior border of the orbit ; all
of which are in marked contrast to those of Halitherium schinzi.
Further, although the molars of Prorastomus sirenvides are much
worn and are only imperfectly shown, yet one of them clearly
exhibits the large anterior talon characteristic of the so-called
Halitherium veronense, such talon being represented in H. schinzi
by a much smaller one. The extremities of the jaws of the Venetian
species being unknown, I can of course say nothing as to the incisors,
which are present in P. sirenoides. From the other evidence
H. veronense may, bowever, be «pretty confidently transferred to
the genus Prorastomus, or, as it should be, Prorastoma, under the
name of P. veronense.

The Coleoptera of which it is the purpose of this paper to give
an account were collected by Mr. J. Whitehead during his residence
from 1886 to the middle of 1887 in the neighbourhood of Kina
Balu, and for the most part in the early months of those years.

This mountain is a plutonic mass rising abruptly on one side to an
altitude of about 13,000 feet, clothed at its base and to about 4000
feet with forest and low trees. . Owing to its summit being bare, a
denuded granitic surface, few insects were obtained by Mr. White-
head above that height.

The best collecting grounds were found to be the river-beds, and
at the altitudes mentioned the usual tropical conditions obtain.
Representing as Kina Balu does the primitive upheaved portions of
this part of the world, which have been in all probability above the
sea during geologic ages, it was to be expected that both its fauna
and flora would prove of the most interesting type, and judging from
the few species of insects now under review this certainly appears
to be the case.

Several species were unfortunately only represented by single speci-
mens, and some of these I am unableat present to determine. ‘The
collection is now in Mr. Alexander Fry’s possession, who has kindly
placed a portion of it at my disposal for description. =

is not toothed, but there are one or two minute serrations at the
base of the spine.

Six specimens of this beetle were obtained by Mr. Whitehead
at about 1000 feet altitude on Kina Balu.

bicostato, elytris interstitiis alternis costato-elevatis.

This new genus is nearly allied to Hncaustes, but has a very
different facies owing to the form of the thorax, and the costz on it
and on the elytra. The front of the prosternum is plain as in
Encaustes, that is to say, not elevated nor brought into a point in
front as in Micrencaustes.

ASMONAX WHITEHEADI, nu. sp. (Plate IV. fig. 5.)

punctatum. Long. 18-19 millim.

Hab. Borneo, Kina Balu and North Borneo (Whitehead).

Wholly black and shining, subopaque in places, as the sides and

lateral reflexed underside of the thorax. Owing to the form of the
thorax, which has the sides sinuate, turned in and downward at the
front angles, and the strong double ridge on the centre of the thorax,
this species has a remarkable and Endomychid appearance; the costate
elytra are an exaggeration of what takes place in such species as

86 REV. H. S. GORHAM ON [Feb. 2,

E. opaca, Crotch. The shortening of the third joint of the antennze
and their bead-shaped appearance show this to bea strongly modified
form. The femora are compressed and sinuous just as in Encaustes ;
the middle tibize have a tooth-like projection externally, just above
the insertion of the tarsi, and are pubescent internally at their
apices. The elytral epipleura are pitchy brown, but not noticeably
so, and have obsolete transverse wrinkles.

I have only seen four examples of this species, viz. those obtained
by Mr. Whitehead. I cannot distinguish the sexes.

ENDOMYCHID£.
AMPHISTERNUS ARMATUS, n. sp. (Plate IV. fig. 3.)

Niger, opacus, obsolete varioloso-punctatus ; thorace subquadrato,
angulis anticis acutis, valde productis ; elytris spinis duabus
acutis c@neo-micantibus, una subhumerali, altera conoidea in

uno basali uno apicali ; femoribus clavatis, apicibus piceis. Long.
8 millim.

Hab. Borneo, Kina Balu (Whitehead).

Rather larger than A. spinicollis ; and at once distinguished from
both the described species of spinous Amphisterni by the two
black tubercles, the produced front angles of the thorax, which are
like those of 4. auriculatus but not reflexed, and by the fiery coppery
or eeneous colour which is seen on the shining parts. The head is
thickly punctured, rather shining, and the antennze have all the
joints from the third to the eighth elongate, the third longer than
the two following united ; the sides of the thorax are slightly angu-
late in the middle and narrow a little to the base; the disk is quite
opaque, with coarse confluent large punctures. Of the elytra the
anterior tubercle has a pitchy tint, the humeral angle is reflexed and
smooth, as is the basal margin; the first lateral spine is a little
below the shoulder, very long and acute, wide at its base, but com-
pressed if viewed from behind, brassy black ; the middle spine more
upright but still divaricating, conoidal at its base; both spines
punctured at their base, as the elytra are. The posterior tubercle is
bluish black and smooth; the apical production of the. elytra is
external to and independent of the sutural angle, which is itself quite
distinct—it is in fact part of the margin itself, the epipleural fold
being continued along it as a groove. The legs are brassy black, the
club of the femora distinctly pitchy.

Several specimens of this-interesting new species were obtained by
Mr. Whitehead.

Hab. Borneo, Kina Balu (Whitehead).

Antenne longer than in #. marginatus, all the joints from the third,
and the club, being longer. The thorax is not so broad, especially
at the base, the hind angles in the male not being nearly so much
produced, but still they are acute; its disk is more uneven, there
being in the single male before me an impressed pit on each side
of the centre ; the elytra have the expanded margin more gradually
widened, so that it is narrower at the shoulders than in Z. mar-
ginatus. The four spots are larger in proportion, and placed nearer
together than in that species, and they are more acuminate at the
apex, and the middle of their disk is much more acutely raised, the
summit of this raised part being conical and nearer the two anterior
spots than the corresponding part in H. marginatus. The front
tibize in the male are nearly straight, not strongly smuous nor dis-
torted as in H. marginatus, but a little compressed laterally with a
short external groove at their apices (for the reception of the tarsi),
but not grooved along their whole length.

This insect has-also some analogy with Z. turritus; but the larger
yellow spots and the dark blue colour of the elytra, as well as the
structure of the tibize, will at once distinguish it.

One specimen, a male, obtained by Mr. Whitehead.

Eumorphus costatus, Gorham, Endom. Ree. p. 34.

Mas, tibiis anticis dente acuto valde distante in medio armatis ;

I believe a single male and female from Kina Balu to be identical
with the species described by myself from two female specimens
from Celebes. The male has the elytra shining, and with an indis-
tinct violet tint, while the female is subopaque and is distinguished
by ashort keel on the elytra at their base near the scutellum. The
yellow spots are large, and cause the species to recall H. quadrinotatus.
The male has the hind angles of the thorax acutely produced, by
which it is at once separated from #. quadrinotatus.

EuUMORPHUS GUERINI.

Eumorphus guerini, Gorham, Endom. Ree. p. 33.

Many specimens of this were obtained by Mr. Whitehead ; all

thorace (femine) subopaco. Long. 9 millim. 9.

Hab. Borneo, Kina Balu (Whitehead).

It is difficult to compare this species with any other of the genus ;

88 ' ‘REV. H. S. GORHAM ON [Feb. 2,

the elytra are very slightly margined, but are acuminate at their
apex, and not very strongly convex. It is entirely black, with the
exception that the elytra have a faintly violet tinge and are very
smooth and shining, the four spots are moderate in size, and round,
very smooth, but not raised; the thorax (of the female) is opaque,
with two rather obsolete basal impressions and a central channel,
its sides are a little angular in the middle, contracted to the front
angles. The antenne are of moderate length, the fourth to the
eighth joints a little longer than wide, the three club-joints subequal,
transverse, not much compressed.

Four specimens were found by Mr. Whitehead. This species
may be placed after EZ. guerini, Gorh.

M. Ernest Olivier has separated under this name specimens of
a Vesta referred by me to Vesta urens, described by myself from
Borneo (cf. Notes from Leyd. Mus. vol. v. 1883, p. 3). Three speci-
mens collected by Mr. Whitehead on Kina Balu agree precisely with
one of these specimens from Sumatra in my possession. As the
specimen which M. E. Olivier redescribes as the type of my V. urens
is now at Leyden, I have no means of forming an opinion on the
specific distinction of V. aurantiaca, but it certainly occurs in Borneo,
as these specimens prove.

nullo modo productis ; pygidio flavo. Long. 20 millim.

Hab. Borneo, Kina Balu (Whitehead).

Head black, eyes moderate ; antenne long and thin for this genus,
nearly asin P. fumigata, the joints much longer than wide and not
serrate ; thorax almost semicircular, with the margins much reflexed,
the diaphanous !unules not very translucent. Elytra entirely smoky
black, two costules moderately distinct for about two thirds of the
length of the elytra, the intermediate one very obsolete; scutellum,
head, legs, and body entirely dull black, with the exception of the
apical ventral segment and pygidium and of the two luminous
patches.

This insect is apparently allied to P. opaca, Bourg., described and
figured in the ‘ Annali del Museo Civico di Storia Naturale di
Genova, vol. ii. 1885, p. 349, t. v. f. 2, from which, however, it differs
by the scutellum being black, by the entirely black legs and body,
and by the absence of the pubescence, and (judging by the figure)
by the thinner and not serrate antenne.

and the pygidium are yellow; the head, breast, and the extreme
base of the legs are yellow, but clouded in parts with fuscous.

3. On the Coleoptera collected by Mr. W. Bonny in the
Aruwimi Valley, Central Africa. By the Rev. H.S.
Goruam, F.Z.S., and C. T. Ganan, M.A.

[Received December 23, 1891.]

In the following paper the Coleoptera of the families Cleride,
Bostrychide, Chrysomelide, Galerucide, Casside, Hispide,
Erotylidz, and Ceccinellidze collected by Mr. W. Bonny during the
Emin Relief Expedition are noticed and the presumed new species are
described, in continuation of the accounts already furnished by
Mr. Bates (P. Z. S. 1890, pp. 479-492, and Mr. Champion, pp. 637-
646). The species of which examples were represented were not
numerous, but the same remarkable coincidence specifically with the
Coleoptera of the West Coast, especially of Old Calabar, will be
noticed.

The Phytophaga, with the exception of the Casside and Hispide,
have been kindly worked out by Mr. Gahan of the British Museum.

C. cyaneo simillimus, sed differt elytris crebre punctatis vir
nitidis, et articulis antennarum quinque ultimis plus dilatatis.
Long. 104 millim.

Resembling very much in colour and general appearance C.
cyaneus, Fabr. The last five joints of the antennz are strongly dilated,
the seventh joint triangular, the eighth to eleventh subquadrate,
transverse, the ninth and tenth each almost as broad as long. Pro-
thorax shining, sparingly and not very distinctly punctured. Elytra
rather dull, thickly punctured. Claws of tarsi cleft, with the inner
division acute, shorter than the outer.

The species may be distinguished from C. compressicornis (which
it resembles in the punctuation of the elytra) by the greater dilatation
of the apical joints of its antennze and by the sparser punctuation of
its pronotum.

6.. COLASPOSOMA ARUWIMIENSE, 0. sp.

Cyaneum, nitidum ; pedibus viridescentibus; prothorace quam latior
viz duplo longiore, dense punctulato ; elytris crebre et sat for-
titer punctatis, lateribus utrisque obtuse iy obsolete uni-
costatis. Long. 8-10 millim.

Dark blue, with the legs metallic green ; wie prothorax, and
scutellum varying to metallic green. Head rather thickly and not
very strongly punctured. Prothorax with its median length rather
more than half the width measured across the base; thickly and
not strongly punctured above; lateral margins rather feebly convex.
Scutellum sparsely punctured. Elytra very thickly and rather
strongly punctured, with the punctures running together to form a
feeble rugosity on the sides just below and behind the shoulders.
Beginning a little behind the shoulder there is a single obtuse and
slightly elevated costa, along the side of each elytron ; this costa is
‘sometimes obsolete. The shoulders of the elytra are slightly
prominent.

The present species may perhaps be only a local variety of a
species (C. fairmairei, Lefév.) occurring in Old Calabar. The latter
has the prothorax much more distinctly punctured, the punctures
being larger and less closely placed together. The colour is very
variable—dark blue, metallic green, and bronze-purple.

of a costa on the sides of the elytra. Possibly only a variety of
the preceding.

In this variety, which occurs also at Old Calabar, the abdomen
is entirely fulvous. In other respects it agrees with the typical
form.

(Specimens of this insect stand in Murray’s collection as
Diacantha beninensis, H.S.G.)

12. HypeRACANTHA FLAVONIGRA, Thoms., var.

Elytra black, with a submedian transverse yellowish band, which
does not reach the outer margins, and each with a sinall testaceous
spot at the extreme apex. ‘This variety is represented by a single
female specimen, which I refer to H. flavonigra, Thoms., on account
of the similarity in the contour of the last abdominal segments. The
ventral segment is rather deeply incised on each side at the apex,
while the median lobe thus cut off bears a shorter incision or notch
placed a little to the right of the middle line. The dorsal segment
is emarginate in the middle at the apex.

13. BonrESIA SERRICORNIS, Thoms., var.

Elytra black ; each with two testaceous patches—one behind the
shoulder and extending inwards on to the disk, the other just behind
the middle. In the typical forms of B. serricornis the elytra are
black with a varying proportion at the apex testaceous.

Mr. Jacoby has referred B. serricornis, Thoms. (Ootheca), to the
genus Aithonea, Baly ; but I can find no sufficient difference by
which to distinguish the latter from Bonesia, Baly. The one genus
was founded upon a male, the other upon a female specimen, each
belonging to a different species. The anterior cotyloid cavities are
usually only very slightly open behind, and may in certain cases
(some specimens of B. murrayi, Baly) be completely closed in,

Resembles P. gigantea, Illig., but differs from this and the other
species known to me by the shape of the pronotum, which, narrowest
at the base, gradually widens up to about the anterior third or fourth,
thence narrowing again to the apex. The last ventral segment
of the abdomen in the female has a rather deep longitudinal pit or
groove along the middle of the apical half of the segment.

the sides, and the apex more narrowly black than in the type ; and
the whole upper surface is more opaque. It possibly represents a
different species.

Long. 12, lat. 9 millim.

The body, head, legs, and antennz of this species are wholly
black, the latter about as long as to reach to the hind angles of the
thorax, their third joint half as long again as the fourth. The
thorax has the extreme edge of the margin blackish ; there are a few
obsolete punctures on each black spot and on the lobe just before
the scutellum. The scutellum is black, but has a yellow mark at
its apex, it is indistinctly impressed. The humerus is prominent ;
the elytra are destitute of marks above or beneath, the extreme edge
is very faintly brownish ; the punctuation is distinct but irregular,
here and there, as near the suture and in one row starting from
the callus, forming series.

Two specimens of this insect were obtained by Mr. Bonny in the
Aruwimi Valley. It has not very much the appearance of an Aspido-
morpha; the claws are, however, pectinate at their base; and in
general structure it seems to me to agree better with that genus .
than with any other known to me.

The inner side of the first four joints of the antenne, the
epistoma, and’a dot on the crown of the head are rufous ; the thorax
and elytra reddish brown, on each side of the middle of the disk of
the former is a black dot of medium size, and this together with the

or any other of its near allies. The prosternum is black and has
the process deeply impressed (as in the allied species); the meta-
sternum is black and shining ; and the abdomen is black, with the
fifth and apical segments rufous, and the three segments preceding
these with a yellow spot at the side of each.

One specimen obtained by Mr. Bonny.

27. CASSIDA STRIGOSA, 0. sp.

Elliptico-ovata, nitida ; elytris marginibus subexplanatis, subviri-

corpore nigro; capite, antennis (articulis duobus ultimis pre-
termissis), femorum apicibus, tibiis, tarsis, margineque toto
flavis. Long. 9, lat. 7 millim.

Not very nearly allied to any species known to me. The outline
is very evenly elliptical, with the whole (both thoracic and elytral)
margin rather widely but evenly flattened. The green colour has
apparently extended over the whole but faded to brown; the suture
is narrowly reddish, and is hardly more distinctly marked beneath
than above. The striz are rather deep, with closely packed
punctures and convex interstices ; a row of larger punctures entirely
surrounds the disk, separating it from the expanded margin.

Two examples.

I propose this name for a very plain-looking Cassida, which I
obtained from the collection of the late Mr. A. Murray, standing
as “C. pallidula, Bohem.,”’ but the species so named by that author
is referred to Mexico. The same insect as Murray’s is in my
collection from other sources named ‘‘ C. pallidula.”’ It therefore
appears that Boheman had suggested this name for the African
insect when he examined Mr. Murray’s collection, but that he sub-
sequently described another species under that name,

C. fuscopunctata is very shining and even, nearly as broad as
long ; in life it would seem to be greenish, from the tint on the disk
and on the thorax in the fresher examples. The reticulation of
the thorax and of the sides in the elytra is very distinct, and there
is a submarginal row of larger cell-like punctures at the edge of the
disk. The disk of both elytra and thorax is evenly and moderately
convex; the underside and antennz except the apex are wholly
luteous.

collection from Old Calabar, now in my own collection.

Mr. Alfred Sharpe, H.B.M. Vice-Consul for Nyassaland, has
kindly shown to me a collection of hunters’ skins and horns of
Mammals formed during his recent stay in the Shiré Highlands and
in other parts of that territory.

A selection of these I have the pleasure of exhibiting this evening,
and I have written a few notes upon them.

the following notes on it :—

“This Antelope is found in a piece of thick scrubby country

near the Murchison cataracts. I have never seen it alive myself,
but have heard of it frequently from the natives, by whom it is
called ‘ Bo’—the o being pronounced very long.

Society.
[Received January 28, 1892.]

(Plate V.)

I have now the pleasure of exhibiting the skull and scalp of an
apparently new Antelope of the genus Budalis, which I propose to
name B. swaynei, after Capt. H. G. C. Swayne, R.E., who has
kindly furnished me with the specimen.

The existence of an Antelope of this form in Northern Somali-
land has long been known to me (ef. P. Z.S. 1885, p. 932), but it
is only within the last few days that I have succeeded in obtaining
specimens of it.

In a series of Mammals from Somaliland lately received from
Capt. Swayne are a good adult skull and head-skin of what he terms
the ‘‘ Hartebeest”’ or “Sig” of the Somalis. One glance at this

head is sufficient to show that the “Sig’’ is not the same as the
Hartebeest of the Cape (B. caama), but more nearly allied to the
Tora (B. tora) of Upper Nubia and to Coke's Hartebeest (B. cokii)
of British and German East-Africa, being in some respects inter-
mediate between these two species.

Fig. 1.

Skull of Bubalis swaynei.

The horns of Budalis swaynei expand widely, after rising from
the base, nearly in the plane of the forehead. They then turn
upwards and slightly inwards. ‘The whole horns are strongly ringed
anteriorly, as in the allied species.

In B. cokii the horns are shorter and not so widely expanded.

In B. tora the horns are quite as long as in B. swaynei, but rise
much more rapidly from the basal portion, then come further forward
and project much further backwards.

The face-skin of B. swaynei is of a dark chestnut, much darker
between the eyes, and with a large black patch on the nose. The
ears are brown exteriorly and light rufous interiorly.

7%

100 MR. P. L. SCLATER ON [Feb. 2,

In B. tora the whole face is of a uniform pale isabelline like the
body.

In B. cokii, of which there are fine examples in Mr. Holmwood’s
collections, which I now exhibit, the whole frout of the head is dark
rufous and the sides of the head pale fulvous.

Thus B. swaynei differs from its two allies both in the structure
of its horns and in the colour of its face.

It may be characterized as follows :—

Besides the new Budalis, Capt. Swayne’s last ccllection contains
- specimens of the following Antelopes :—

this species, locally known as “ Alikhud.”

4, Gazeua poizeint, Kobl; Thomay, /. ¢.

A flat skin and a head-skin of this species, which Capt. Swayne
terms the “ Low-country Gazelle” or ‘‘ Dero” of the natives.

I fear it was I that led Mr. Lort Phillips into the error of calling
this Gazelle “ spekei ”—a name which, as Mr. Thomas has shown,
belongs to the next species of the ‘‘ High-country.”

There is now a fine mounted specimen of this Gazelle in the
British Museum and several skins. The present flat skin is
decidedly rather paler in colour than the mounted specimen in
the British Museum, but not otherwise different.

5. GAZELLA SPEKEI, Blyth ; Thomas, op. cit. p. 210.

Capt. Swayne sends a skull and head-skin of a female of this
Gazelle, which he calls the “ Big-nosed Gazelle.” The horns of
this example are particularly long and straight.

There is now also a good mounted specimen of this Gazelle in
the British Museum, obtained from Herr Menges. Besides the
points of difference pointed out by Mr. Thomas, it may be noted
that the lateral stripe is much darker, nearly black in the present
species.

6. GAZELLA S&MMERRINGI (Cretschm.) ; Thomas, J. c.
Three good skulls of males and five head-skins are in the collection.

This makes 11 species of Antelopes of which Capt. Swayne has
forwarded specimens from Berbera. 1 much regret that he has not
sent me accompanying notes on their habits and exact localities, but
he promises to do so.

At least two other Antelopes are found in Somaliland, namely,
a Water-buck (Codus sp. ine.), as mentioned by Mr. Lort Phillips
(P. Z.S. 1885, p. 932); and a ‘small red Antelope of the Klip-
springer kind; horns about 2 inches long; female bornless; same
size as Alikhud: called ‘ Beira’ by the natives”: as described by
Capt. Swayne in his letters. Capt. Swayne’s brother, Lieut. E. J.
Swayne, Bengal Staff Corps, met with this species in the Gadaburri
country, but was not able to shoot a specimen. It may possibly
be a Cephalophus.

6. On Numerical Variation in Teeth, with a Discussion of
the Conception of Homology. By W. Barrson, M.A.,
Fellow of St. John’s College, Cambridge.

[Received February 2, 1892.]

The following paper is an abstract of facts regarding the Nu-
merical Variation of Teeth and of certain conclusions as to the
nature of the conception of Homology asapplied to Teeth which those
facts have suggested. The observations concerning teeth form part
of an investigation of the Variation of Multiple Parts in general, and
I hope that before long the results of this work will be published in
a complete form by Messrs. Macmillan, to whom I am much
indebted for leave to use the blocks with which this paper is illus-
trated.

In an abstract it is clearly impossible to set forth the precise
value and significance of the Study of Variation as a clue to the
problems of Descent; but since by most this subject is wholly
neglected, it may be well to state in the fewest words why it is that

1892. ] NUMERICAL VARIATION IN TEETH. 103

this method of investigation is not merely a good one, but perhaps
the best open to us.

The reason, then, is this. We assume that the transition from
one form to another takes place by Variation. If, therefore, we
ean see the variations, we shall see the precise mode by which
Descent is effected. Now the problem of Descent includes the
problem of Homology, and, therefore, in any case of supposed
Homology between organs the ideally best proof or disproof of such
a supposition is to be had by appeal to the facts of Variation. For
the statement that an organ of one form is homologous with the
organ of another form means that there is between the two some
connexion of Descent, and that the one organ has been formed by
modification of the other or both by modification of a third. The
precise way in which this connexion exists is not defined, and,
indeed, has scarcely ever been considered, and though such a con-
sideration must be hereafter attempted, the matter cannot be
discussed here. We must be content for the present with the
belief that in some undefined way there is a relationship between
homologous parts, and that this is what we mean when we affirm
that they are homologous. In the case of the homologies of Teeth,
we are concerned with the application of this belief or principle to
the case, not of a single organ, but to Multiple Parts arranged in
Series. If, then, the whole series of teeth in one form is homolog-
ous with the whole series in another, we have now to consider how
far we can extend the principle to the case of individual members of
the two series. This is the question which is again and again
arising with regard to Multiple Parts, but there are still no general
principles by which it may be decided.

But though no one has told us the steps by which the Numerical
Variation of teeth proceeds, there is nevertheless a received view by
which it is sought to interpret the phenomena, and though there
are several schemes upon which the homologies of teeth are defined,
all are alike based upon one principle, which may be stated as
follows.

It is believed that in the case of mammals, perhaps excluding
the Cetacea, the series of teeth consisted originally of some maxi-
mum number from which the formule now characteristic of the ©
several forms have been derived by successive diminution. On this
view the series is believed to be always composed of definite and
individual members, which in any given form are either present or
absent ; and the business of the homologist is then to determine
which in each case is present and which absent. This hypothesis,
of course, involves a definite conception of the mode in which
Variation works, and it is most important to realize this clearly.
For if it is true that each member of the Series of Teeth has in every
form an individual and proper history, it follows that if we had
before us the whole series of ancestors from which the form has
sprung, we should then be able to see the history of each tooth
distinctly and severally in the jaws of each of these progenitors. In
such a series the rise of one individual tooth and the decline of

104 MR. W. BATESON ON [Feb. 2

another would then be manifest. Each would then have its
individual history, just as a Fellowship of a College or a Canonry of
a Cathedral has an individual history, being handed on from one
holder to his successors, some being suppressed and others being
founded, but none being merged into a common fund. In other
words, the received view of the nature of homologies in teeth
assumes that in Variation the individuality of each member of the
series is respected.

The difficulty in applying this principle is notorious, not only in
the case of teeth but in all cases of Multiple Parts, such as digits,
phalanges, &c. ; and when the actual evidence of Variation is before
us, the cause of this difficulty will become apparent enough, for it
will be found that though Variation may sometimes respect the
individual homologies, yet this is by no means a universal rule ;
and, as a matter of fact, in all cases of Multiple Parts, as to the
Variation of which any considerable body of evidence has been
collected, there are numerous instances of new forms arising in
which what may be called the stereotyped or traditional individuality
of the members has been superseded.

The present paper concerns the case of Teeth only, and even of
this part of the evidence only a fragment can be given in this
abstract, but perhaps it may suffice at least to indicate some of the
possibilities which are opened up by the Study of Variation.

The material examined has consisted chiefly of specimens in the
British Museum and the Museums of the College of Surgeons,
Leyden, Oxford, and Cambridge, the Paris Museum of Natural
History, and several smaller collections. I have to thank the
authorities of these several museums for the great kindness I have
received from them in the course of my work ; and in particular I
must express my indebtedness to Mr. Oldfield Thomas, of the
British Museum, for the constant help and advice which he has
given me, both as regards the subject of teeth generally, and
especially in examining the specimens in the British Museum.

For various reasons I have for the most part limited myself to
the following groups :—Primates (excepting Lemuroidea), Carnivora
(Canide, Felidee, Viverridee, Mustelidee, and Phocide), Marsupialia
(Phalangeridz, Dasyuride, Didelphyide, part of Macropodide, &c.).

Except in the case of teeth which are the terminal members of
series, such as the first premolar or the last molar, very few facts of
importance concerning the process of reduction in number were
seen. From the fact that such cases are generally more or less
ambiguous, they must be reserved for fuller treatment. For the
present it must suffice to give a brief account of some of the more
remarkable phenomena relating to increase in number of teeth.

The statistics relate to about 2500 skulls belonging to various
orders, and the comparative frequency of supernumerary teeth in
some of the different groups is interesting if only from its para-
doxical character.

Primates.—Of the three larger Anthropoids—Orang, Chim-

1892. ] NUMERICAL VARIATION IN TEETH. 105

panzee, and Gorilla—141 normal skulls were seen, and 11 cases
of supernumerary teeth, or nearly 8 per cent. (in addition
to 7 recorded cases known to me). On the other hand, no
case was seen in 51 skulls of Hylobates, which were all normal.
And of Old World Monkeys other than these, I found only
two cases in 423 skulls, or less than °5 per cent.

In the species of Cebidz and in Afeles supernumerary
teeth are common, five cases being found in 131 skulls, or
nearly 4 per cent. (in addition to 4 recorded cases); while in
92 skulls of other New World Monkeys there was not one case.

Puocip2.—139 normals, 11 cases of supernumerary teeth, or
7°5 per cent.

Orariip#.—121 normals, 5 cases of supernumerary teeth, or
4 per cent.

Canip2.—Of wild Canidz, 289 normals were seen, and 9 cases of
supernumerary teeth, or 3 per cent. (in addition to numerous
recorded cases).

Of Domestic Dogs, including Pariahs, &c., 200 skulls were
normal and 16 had supernumerary teeth, or 8 per cent.
(besides many recorded cases).

Fetipz.—Of wild Felidz, 278 normals and 6 cases of super-
numerary teeth, or more than 2 per cent.

Of Domestic Cats, 35 normal and 3 cases of supernu-
merary teeth, or 9 per cent.

Viverrip#.—94 normals (not regarding variations affecting the
first premolar only) and 4 cases of supernumerary teeth.

Owing to the great variability of the dentition of some groups of
Marsupials and the difficulty of deciding on the normal formula, it
would not be profitable to give summary statistics which should be
satisfactory.

It will be seen that, so far as the statistics go, supernumerary
teeth were more common in domestic Dogs than in wild Canide,
and though the number of Cats seen was small, the same is true in
their case also as compared with wild Felide. But though it is
received by many almost as an axiom that domestic animals are, as
such, more variable than wild ones, and though the figures some-
what support this view, it is necessary to point out that such a
deduction should be made with great caution. For while it is trne
that the domestic Dog is more variable in its dentition than wild
Dogs, it is not true that it is much more variable than many other
wild animals, as, for example, the Anthropoid Apes, some of the
Phocide, several genera of Marsupials, and others. The doctrine
that domestication induces or causes Variation is one which will not,
I think, be maintained in the light of fuller evidence as to the
Variation of wild animals. It has been suggested by the circumstance
that so many of our domesticated animals are variable forms, and that
so little heed has been paid to the variation of wildforms. To obtain
any just view of the matter, the case of variable domestic species
should be compared with a species which is variable though wild.

106 MR. W.'BATESON ON [Feb. 2,

The case of the great variability of the teeth of the large An-
thropoids, which is shown not merely in numerical changes,
but in frequent abnormalities of position and arrangement, is most
striking, both when it is compared with the great rarity of variations
in the teeth of the Old World Monkeys and the comparative
rarity of great variations even in Man. If the Seals or the
Anthropoids had happened to be domesticated animals, I do
not doubt that many persons would have seen in this variability
a consequence of domestication. When the whole evidence is
examined, it will be found that we can make no generalizations of
this kind, and that the variability of a form is, so far as can be seen,
as much a part of its specific characters as any other feature of its
organization. A few curious cases may be given in illustration.
Of Canis cancrivorus, a S. American Fox, I know the following
specimens only (in the British Museum)—normals (numerically) :
one whole skull with lower jaw, one skull without lower jaw, and
one lower jaw without a skull, and in one of these right m® is much
larger than the corresponding left tooth; abnormals: two skulls
have m! on both sides, and a third has a large “ odontome” formed
as 4 small molars growing from right m’. Of Felis fontanieri, an
aberrant Leopard, two skulls only are known (British Museum), and
both of these show dental abnormalities, one having supernumerary
left m2, and the other having aa additional talon to right p*, making
it almost a “ bigeminous”’ tooth. In the Seals only three cases of
reduplication of the first premolar were seen, and two of these were
in Cystophora cristata (Leyden and Cambridge). Evidence of this
kind might be multiplied indefinitely.

The following cases are chosen as representative examples or
‘Prerogative Instances” of different classes of phenomena which
occur in connexion with increase in number of teeth. It will be
understood that the cases are selected as illustrations, and that in
order to have a full appreciation of their significance, the whole
body of evidence must be taken together, for scarcely any two cases
are exactly alike.

Division of individual Teeth.

Ommatophoca rossii-—Of this form two skulls only are known,
namely, those in the British Museum. One of them has the

arrangement usually found in Phocide, viz., five teeth behind the

‘ Ake - % - 2-2 any 5
canines, giving the formula:—i. =, ec. =: p-+m.=-. By the

55

analogy of other Seals, these five teeth are p. > m. i. The other

specimen is exceedingly remarkable (fig. 1). In it the incisors
and the canines are the same as in the first specimen, but the first
tooth behind the canine on both sides in the lower jaw and on the
right side in the upper jaw has a very peculiar form, having a deep
groove passing over the whole length of the tooth on both its outer
and inner sides. These grooves extend from the tip of the root
along both sides of the crown, and thus imperfectly divide each
tooth into an anterior and a posterior half. The cusp of each tooth

1892.] NUMERICAL VARIATION IN TEETH. 107

is also divided by the grooves so as to form two small cusps. Each
of these teeth is therefore an imperfectly double structure, and may
be described as being just halfway between a single tooth and two
teeth.

On the left side in the upper series, as the vis-a-vis to one of
these double teeth, there are two complete teeth, standing near

Ommatophoca rossii, having the first upper premolar on the right side bigemi-

together, but having separate sockets divided from each other by a

bridge of bone. The dental formula for this skull taken as it stands
ise—1- a c. — p- +m. —, for since the bigeminous teeth are

not completely divided into two, they must be reckoned as single
teeth.

Phoca grenlandica.—A specimen is preserved in the Leyden Mu-
seum having the arrangement shown in the figure (fig. 2’, p. 108).
The dentition of the lower jaw is the same on both sides. In the
upper jaw there are on the left side sx teeth behind the canine,
while on the right side there are five, the normal number. But
upon examination, one of these teeth, namely p‘ of the usual nomen-
clature, is an abnormally large tooth, being especially thick in a
transverse direction, and has besides a deep cleft in the crown,

1 This figure was kindly drawn for me by Mr. J.J. Lister.

108 MR. W. BATESON ON [ Feb. 2,

which is thus partially divided into two. Upon comparing this with
the series on the left side, it appears that two of the six teeth stand
level with this bigeminous tooth, and both bite between p‘ and m'
of the lower series, though there is no crowding in the jaw owing
to the large spaces which exist between the normal teeth of this
species. There is, therefore, no doubt that the fourth premolar is
on the left side bodily represented by two distinct teeth, each of

Phoca grenlandica, having the fourth upper premolar on the right side bigemi-
nous, and on the left side represented by two complete teeth (shaded).

which is perfect and complete, while on the right side the process of
division is incomplete.

In the Paris Museum (A 2897) there is a specimen of P. gren-
landica in which the second upper right premolar is represented by
two teeth, each of which has two roots; but these two teeth stand
at the same level in the arcade, one being external and the other
internal. On the left side the second upper premolar is incompletely
double, the crown being partially divided by an oblique constriction
into an anterior and internal portion and a larger posterior and ex-
ternal part. The former has one root and the latter has two.

It is thus seen that reduplication of teeth may occur in such a
way that a tooth which is normally single may be represented by
two teeth, and that the two teeth thus formed may either (1) both
take places in the ordinary series, or (2) may stand externally and
internally respectively.

Substitution of two teeth for one, both being in series, was seen
in Ommatophoca rossii (p'), Phoca grenlandica (p*), Otaria ursina
(p’), Brachyteles hemidactylus (p'), Phalanger orientalis (p"), ditto
(p’), Myrmecobius fasciatus (i), ditto (i#). Probably also cases of
the presence of two similar small teeth in place of the first premolar
in the Canidee and Felidze should be looked on as belonging to this

1892.] NUMERICAL VARIATION IN TEETH. 109

class, though the materials which support this view cannot easily be
given in brief.

Partial or complete reduplication of teeth occurring in the second
way was seen in P. greenlandica (p*), Otaria cinerea (m"), Canis me-
somelas (p*), Vison horsfieldii (p*), Herpestes orientalis (p*), Herpestes
gracilis (p), Felis domestica (p'), ditto (p*), Phalanger orientalis (#*),
&e.

The power of a single organ to reproduce itself is of course not
confined to teeth, but will be shown to be present in many different
kinds of organs, and especially in those which are ‘arranged as a
Series of Multiple Parts.

Variation in Terminal Teeth when a new member is added to the
series.

This is a phenomenon which is most instructive as a guide to the

nature of the process by which Multiple Parts are formed. It may
be stated generally that if the tooth which is the last of a normal

110 MR. W. BATESON ON [Feb. 2,

series is relativelya small tooth, as, for example, m? or m* in the Dog,
then in cases of an addition to the series by which this terminal
tooth becomes the penultimate it will be found that this penultimate
tooth is larger and better developed than the corresponding ultimate
tooth of a normal animal of the same size. Of this phenomenon
two examples must here suffice.

The first is a skull of Canis azare in the Leyden Museum (fig. 31,
p- 109). In this figure, I and II represent the back-teeth of this
abnormal specimen, I being the upper, and II the lower jaw. By
the side of thése are shown the upper and lower jaws of a normal
specimen of rather larger absolute size. In the upper jaw thereis a
supernumerary m* on both sides and the great enlargement in m’ and
especially in m?* is very striking. In the lower jaw there is no extra
tooth, but the molars are considerably larger than the normal size.

The next case is that of Dasyurus maculatus, having an extra

molar in the left upper and both lower jaws. In this case, owing to
the great difference which normally exists both in shape and size
between the last tooth and the last but one, some obscurity is intro-
duced by the changes associated with the presence of an extra tooth,
and it would be difficult to determine the nature of the upper teeth
if this phenomenon of Variation were unrecognized. The structures
are shown in fig. 4, A being the right upper jaw of a normal
specimen, while B and C are the jaws of the abnormal form (Brit.
Mus. 983 6). The normal specimen is unfortunately much larger

than the other, which Mr. Thomas tells me is abnormally small for
the species. In the upper jaw of a normal skull there are two small
premolars (p' and p* of Thomas) and behind these four molars.
The molars increase in size from the first to the third, which is by
far the largest. Behind the third is the fourth molar, which is
much thinner than the others. On comparing the abnormal skull
with the normal one it is seen, firstly, that on the left side there are
seven teeth behind the canine, while on the right side there are
‘only six such teeth, as usual. On the right side, however, the last
molar has not the thin flattened form of the last molar of a normal
skull, but is a fair-sized thick tooth. In each lower jaw there are
seven back-teeth instead of six. In making a more detailed com-
parison, the first five teeth on each side are clearly alike, while from
its form the seventh on the left side might be thought to represent
the normal sixth, and this is the view originally proposed by Mr.
Thomas in his ‘Catalogue of Marsupialia,’ p. 265, note. The
difficulty in this view is that it offers no suggestion as to the nature
of the sixth tooth on the right side. In the light, however, of what
has been observed in other cases of extra molars, it seems likely that
ou the right side m* has been raised from a small tooth to one of
fair size, while on the left side the process has gone further, m4
being still larger and another tooth having been formed behind it.
Mr. Thomas, to whom I am greatly indebted for having first shown
me this specimen, allows me to say that he is prepared to accept the
view here suggested.

This phenomenon, of the enlargement of the terminal member of
a series when it becomes the penultimate, is not by any means con-
fined to teeth, for the same is true in the case of ribs, digits, &c.,
and it is possibly a regular property of the Variation of Series of
Multiple Parts which are so graduated that the terminal member is
the smallest. This fact will be found of great importance in any
attempt to conceive the physical process of the formation of Mul-
tiple Parts, and, pending a full discussion of this and kindred pro-
cesses, it may be remarked that such a fact strikingly brings out the
truth that the whole Series of Multiple Parts is bound together into
one common whole, and that the addition of a member to the series
may be correlated with a change in the series itself, and may occur
in such a way that the general configuration of the whole series is
preserved. In this case the new member of the series seems, as it
were, to have been reckoned for before the division of the series into
parts. This is, of course, only one way in which numerical Variation
may take place; for, as was described in the previous section, ad-
ditions to the series may be formed by the division of single members
of the series, and in this case the configuration and proportions of
the rest of the series remain normal. Examples of these two distinct
methods of numerical Variation occur among Series of Multiple
Parts of many kinds (digits, vertebree, &c.).

of the series have been met with. Cases of this kind are known in the
tessellated teeth of Rhinoptera (an Eagle-Ray), the most remarkable
being that described and figured in R. jussieut by Smith Woodward
in Ann. & Mag. N. H. ser. 6, vol. i. 1888, p. 281. In this specimen
(fig. 5, upper diagram) the number and arrangement of the teeth were
quite different on the two sides, those on the one side being normal,
while those on the other were unlike any known form. This new kind
of tessellation was, nevertheless, so regular and definite that had it
been existing on both sides the specimen would undoubtedly have

been made the type of a newspecies. There is, indeed, in the British
Museum a unique pair of jaws in both of which a very similar tes-
sellation occurs in a nearly symmetrical manner, and though this
specimen has been described as R. polyodon, it is by no means unlikely
that it is actually a ‘“‘sport” of this kind derived from the usual
formula of Rhinoptera.

One case in Mammals may be mentioned. This is a specimen
of Ateles marginatus (Brit. Mus. 1214 6) having four premolars
in each upper jaw instead of three (fig. 6). The lower
jaw is normal. ‘There is nothing in this specimen to indicate

Proc. Zoo. Soc.—1892, No. VIII. 8

114 MR. W. BATESON ON [Feb. 2,

that any one of these teeth should be considered supernumerary
more than any other; and in the absence of such evidence it
would, as I think, be best to regard the four premolars in this
specimen as collectively representing the three premolars of the
normal. For just as a stick may be broken into three pieces or into
four, so would it seem to be with Multiple Parts. The epithelium
which normally gives off three enamel-germs has here given off four
such germs, and I believe that it is as impossible to analyze the four
teeth and apportion them out among the three teeth as it would be
to homologize the sides of an equilateral triangle with the sides of a
square of the same peripheral measurement, or to homologize the seg-
ments of a 4-rayed Sarsia* with segments of its 6-rayed “sport.”
To make such an attempt would be to disregard the plain and ob-
vious indications of the true nature of the phenomenon, and any
theory of Homology which recognizes this class of problem as profit-
able or legitimate is, I believe, founded upon a wrong conception
of the physical process of Division. .

For, after all, it is with a process of physiological Division
that we have here to do, and the Division which results in the
formation of a series of Multiple Parts is probably a manifesta-
tion of the same physical process as the Division of a cell or the
segmentation of an ovum. Whoever will discover by what physical
process an ovum segments will give us the key to the problem of the
segmentation of tissues into Series of Multiple Parts; and though
we are far enough from having any such knowledge, we should at
least recognize that this is the problem to be dealt with, and any
working hypothesis of the nature of Homology should be, at
all events, in harmony with what is known of the processes of
Division and should be founded upon them. Now the ordinary
conception of the relationship of Homology as defined above, though
it has been a useful instrument as a basis of nomenclature and so
forth, is nevertheless inconsistent with the facts of Division and is
founded on assumptions which are not justified, suggesting a view of
the physics of Division which is wrong.

In order to appreciate this, let the reader consider, for example,
the case of Ommatophoca rossii given above. Judged by the ordi-
nary rules of morphological criticism, this specimen shows one or
both of two things :—

(1) The first premolar of Ommatophoca may in itself represent
two premolars of an ancestor.

Or (2) In the descendants of Ommatophoca the single first pre-
molar may be represented by two distinct and several pre-
molars.

1 Sarsia is the Medusa of a Gymnoblastic Hydroid (Syncoryne). The
normal] form has 4 radial canals, 4 ocelli, and 4 tentacles. ‘Three specimens
having six of each of these parts are recorded, two (American) by L. Agassiz,
Mem. Amer. Acad. Sci. iv. 248, pl. v. fig. 5, and one (British) by Romanes,
Journ. Linn. Soc. xii. p. 527. All of these were radially symmetrical.

1892.] NUMERICAL VARIATION IN TEETH. 115

One or both of these propositions may be true. If the division of
the other three first premolars were as complete as that of the
left P' there would be no indication of their origin. But if it is
possible for a premolar to represent or to be represented by two
premolars, without any visible indication of its double nature, may
not the same be true of the premolars of other forms? May it not
be true of teeth generally? And if it is true, how are the homologies
of teeth to be determined? Nevertheless teeth are almost preemi-
nently amenable to this kind of treatment. ‘They have been studied
with immense care. The facts which they present, and on which
their homologies are to be determined, are remarkably compact, and
of all Series of Multiple Parts they offer the best chance. But ex-
amined in the light of a knowledge of the facts of Variation, that
process is found to be capable of occurring in a way which precludes
the possibility of carrying out an analysis of the relation between
the parts and suggests that such relationship need not necessarily
exist at all. This subject cannot now be discussed further; but if
any one wishes to realize the difficulties suggested by the Variations
of which instances have been given, let him read some good dis-
cussion of dental homologies, as, for example, Thomas’s excellent
paper ', with these cases in his mind, and as he reads let him ask
himself what margin is left for the oceurrence of phenomena like
this. Such schemes as that alluded to, though they have done a
most useful work, and though they are ingenious, logical, and orderly,
are orderly because they are made without regard to the ways of
Variation, which is arbitrary and capricious and follows no order
that we have yet devised.

An illustration will perhaps help to make clear the point at issue.
The received view of homology supposes that a varying form is
derived from the normal much as a man might make a wax model
of the variety from a wax model of the type, by small ad-
ditions to, and subtractions from, the several parts. This may,
to our imaginations, seem, perhaps, the readiest way by which
to make the varying form if we were asked to do it; but
the natural process differs in one great essential from this. For
in nature the body of the varying form has never been the body
of its parent and is not formed by a plastic operation from it;
but in each case the body of the offspring is made again from the
beginning, just as if the wax model had gone back into the melting-
pot before the new model was begun.

The present system of Homology must probably be retained as a
basis of notation, imperfect though it is and though it is founded on
a misconception of essential facts. It is likely that many will be
disposed to doubt the reality of this misconception. and I can only
ask that they should suspend judgment until the whole evidence can
be produced. In the meantime this summary of facts and conclusions
is put forward, together with a few “ Prerogative Instances,” in the
hope that some one may be thereby attracted to a most powerful
and fascinating method of zoological research.

February 16, 1892.
Osbert Salvin, Esq., F.R.S., Vice-President, in the Chair.

Mr. W. T. Blanford exhibited two heads (one mounted) and a skin
of the Yarkand Stag. The specimens had been lent for exhibition
by Major C. S. Cumberland, who shot the animals in the woods on

and Water’ (vol. li. p. 318, March 14th, and p. 446, April 11th,
1891).

Mr. Blanford made the following remarks :—

The Stag of Eastern Turkestan was first brought to notice by

presented by Mr. A.O. Hume. The skull measures in basal length 14 inches,
in breadth across the orbits 6°75; the two horns are 35 and 34 inches long
respectively, measured along the beam and round curves, and the girth of the
right horn, just above the burr, is 6°75 inches.

some of the officers who accompanied the Mission under Sir D.
Forsyth sent by the Government of India to Yarkand and Kashgar
in 1873; and by Colonel Prejvalski, who found this Deer common
around the Lower Tarim and Lobnor in 1876, and noticed it (Pet.
Mitth., Erg. Heft, No. 53, p. 9) as Cervus maral. In the ‘Mam-
malia’ of the Scientific Results of the Second Yarkand Mission,
p- 92, this animal is mentioned, and a photograph of its horns
obtained by Mr. R. Shaw noticed. From the photograph it was
surmised that the horns resembled those of C. affinis.

Several fine heads have since been obtained by Mr. A. O. Hume
from Yarkand; of these three are now in the British Museum. All
are very similar: they have 5 tines on each horn, as is generally the
case in C. cashmirianus and C. offinis, but differ greatly from the last
named in the curve of the beam, and somewhat from C. cashmirianus,
to which, however, they appear very closely allied. At the same time
the horns of the Tarim Stag appear always distinguishable as
spreading less and by the terminal tine never being curved inwards to
anything like the extent that it is in C. cashmirianus. There is
very little resemblance to C. maral, in which the crown appears to
consist of more than two tines.

C. maral, C. cashmirianus, and some other Deer may be ultimately
classed as subspecies of C. elaphus. The Yarkand Stag is apparently
another subspecies, distinguished by its unusually straight horns. As
a distinctive name is useful for these races, each of which appears to
occupy a small isolated area, the name C. yarkandensis may be
applied to the Yarkand and Tarim Deer as a subspecific name, it
being understood that the form is not regarded as specifically distinct
from C. cashmirianus.

The skin of the body is unusually pale in colour, with a well
marked caudal disk.

Mr. Sclater exhibited and made remarks on some “ Spinning or
Japanese Mice,” as a particoloured breed of Mus musculus or one of
its allies, now commonly kept in captivity, is usually called. The
curious habit of spinning round and round after their tails like a
kitten was highly developed in this breed and continually exercised.
It was very difficult to imagine a reason how this habit originated,
and why it was so readily inherited.

Mr. Sclater exhibited a series of mounted heads of Antelopes
belonging to Capt. H. G. C. Swayne, R.E., and made the following
remarks :—

My communication upon Capt. Swayne’s Antelopes to the last
meeting having been rather hurried owing to stress of time, I thought
it might interest the Society to examine Capt. Swayne’s private col-
lection of heads, which have been beautifully mounted for him by
Messrs. Rowland Ward & Co. of Piccadilly, and kindly sent here for
exhibition.

118 MR. F. E. BEDDARD ON ANTHROPOID APES. | Feb. 16,

They belong, as-will be seen, to the eight following species :—

(1) Bubalis swaynei. (5) Lithocranius walleri.
(2) Neotragus saltianus. (6) Oryx beisa.

(3) Gazella semmerringi. (7) Strepsiceros kudu.
(4) Gazella spekii. (8) Strepsiceros imberbis.

Amongst these, I am specially pleased to be able to draw atten-
tion to a beautifully prepared head of Swayne’s Hartebeest (Bubalis
swaynet), the new Antelope of which I pointed out the characters at
the last meeting. It will be observed that this mounted head fully
confirms the points of difference between Swayne’s Antelope and
the allied species (B. tora) on the North, and Coke’s Hartebeest
(B. cokii) on the South. From both these species, without reference
to the form of the horns, of which I spoke on the former occasion,
the new species is at once distinguished by the dark chestnut colour of
the whole head and neck, which is relieved by the black face below
the eyes and the light isabelline of the nose and lips. The ears also
are of an isabelline tint, with the hairs edging the interior rim nearly
white.

This, I may remark, is the fourth new species of Antelope that we
have lately received from Somaliland, and it is even possible that
the Water-buck (Cobus) met with, but not obtained, by Mr. James’s
party in the interior, as well as the small Antelope called “ Beira”’
spoken of by Capt. Swayne, may turn out to be novelties also.

Mr. Sclater gave the following list of the known Antelopes of
Northern Somali-land and their native names :—

Mr. A. Smith Woodward exhibited and made remarks on speci-
mens of the supposed jaws and teeth of Bothriolepis from the Upper
Devonian Formation of Canada.

Mr. F. E. Beddard read a paper entitled “Contributions to the
Anatomy of the Anthropoid Apes.”

This contained a description of the external characters, brain, and
muscles of the Bald-headed Chimpanzee “Sally,” and the reputed
Lesser Orang “ George,” lately living in the Society’s gardens.

The. Bald-headed Chimpanzee, Troglodytes calvus, was established
as a second species of Chimpanzee by M. Du Chaillu. The Natural

1892. | MR. F. E. BEDDARD ON ANTHROPOID APES. 119

History Museum possessed skins and skeletons of this Anthropoid
which were obtained from M. Du Chaillu ; a comparison of these
with the skin and skeleton of “ Sally” showed that the Chimpanzee
which lived for so many years (from 1883 to 1891) in the Society’s
Gardens was undoubtedly referable to Du Chaillu’s Troglodytes
calvus. The late Dr. Gray had refused to admit the validity of
this species; but the present paper afforded additional reasons for
accepting T'roglodytes calvus as a distinct form of Chimpanzee, not
synonymous with the 7. ¢schego of Duvernoy.

The animal was unfortunately so diseased that the viscera could
not be satisfactorily studied ; the bones, too, exhibited pathological
appearances, so that the supposed differences in the skulls of
T. calvus and T. niger must probably be liberally discounted. The
animal had acquired the permanent incisors and bicuspids of the
upper jaw; the first molar being the only one of the molar series
which wasin place. The canines were along way from their defini-
tive position, and protruded through the bone. In the lower jaw
the only representatives of the milk-dentition which had not been
replaced were the canines. The condition of the teeth, were their
possessor a human being, would suggest the age to have been
between ten and eleven years: this was in all probability the age of
the Chimpanzee.

The muscular anatomy did not, as might be expected, show
many differences from the common Chimpanzee, 7’. niger.

At present it was impossible to state how far even these slight
differences might be individual. Although so many anatomists—
Brith], Bischoff, Humphrey, Macalister, Sutton, Chapman, Vrolik,
Gratiolet, and Alix, &e.—had recorded their dissections of 7’. niger,
the normal muscular structure of even that species was not yet
beyond dispute. And as the present paper contained the only
account yet published of the myology of 7’. calvus, the facts stated
must be taken for what they were worth.

In the following table the principal differences between T’roglo-
dytes calyus and Troglodytes niger were shown (according to Sutton’s
account of the myology of the latter) :—

120 MR. A. G. BUTLER ON [Feb. 16,

In the brain the chief differences from 7’. niger were: the greater
depth in proportion to the length ; the Sylvian fissure was much more
upright than in the common Chimpanzee, and therefore approached
the Gorilla and the other Anthropoids; the common Chimpanzee
came nearest to man in the direction of this fissure. The middle lobe
of the cerebellum was overlapped posteriorly, and nearly concealed,
by the two lateral lobes.

The Orang “ George”’ was believed on its arrival to be an adult
example of the Lesser Orang, Simia morio, originally described by
Sir R. Owen. It proved to be a much younger specimen than had
been supposed. All the milk-teeth were present ; and, although
they were unusually worn, none had been replaced by the permanent
teeth. The shape of the head was, however, rather different from
that of the typical Simia satyrus, being distinctly longer and not so
markedly brachycephalic.

The external characters, particularly the hands and feet, were
described and illustrated, and a full account was given of the muscular
anatomy of the limbs.

This paper will be published entire in the Society’s * Transactions.’

The following papers were read :—

Walker’s description of this species is so bad that without exam-

with M. pontioides.

for identifying it for me as his species.

CHALCOSIA INDISTINCTA.

Chalcosia indistincta, Swinhoe, in litt.
One imperfect female.

ARCTIIDE.
MypDRoTHAUMA, N, gen.

Nearest to Zupyra, the primaries a little narrower, the subcostal
branches emitted regularly from the cell instead of branching off
from the main nervure; the second and third median brauches
wider apart at their origins; the secondaries with strongly arched
costal margins; three instead of two median branches; palpi
extremely short and porrected, instead of very long and almost
erect; tibial spurs also very short; abdomen much _ broader,
flattened and tufted at the sides. From Mydrodowa, to which it is
also allied, it differs in its considerably narrower primaries with
sinuous instead of arched inner margin ; in the important point of

sembles on the under surface, in its much inferior size and in the deep glistening

the absence of an accessory cell, in the non-furcate subcostal
branches, in the very important point of the absence of a costal
vein to the secondaries, the simple instead of forked subcostal vein,
the presence of a radial vein, which in Mydrodoza is absent, and
the more slender legs with better defined tibial spurs. Altogether,
in spite of a similarity in the palpi of Mydrodoxa and Mydro-
thauma, the latter is decidedly more nearly allied to Hupyra.
Type IZ. ada.

MyprorHauMa Apa, n. sp. (Plate VI. fig. 1.)

do. Nearest to M. semperi (Mydrodowa semperi, Druce, P. Z. 8.
1885, p. 519, pl. xxxii. fig. 1), which is a true Mydrothauma, but
far more beautiful; primaries above velvety greenish black, with
three metallic violet spots forming an arched stripe across the base ;
a narrow band of gold with diffused greenish edges across the basal
third, its inferior extremity not quite reaching the inner margin ;
the disk almost wholly occupied by two large unequal golden spots
or patches with diffused greenish edges: secondaries intense seri-
ceous black ; the costal area greyish; a minute steel-blue spot at
the end of the cell ; a trifid subeuneiform hyaline patch divided by
the second and third median branches: head and collar vivid
carmine; thorax velvety black, the meso- and metathorax clothed
at the sides with deep smoky brown hair: abdomen blackish
brown, almost black, with velvety black lateral tufts; each
segment marked with lateral metallic violet-blue dashes: wings
below very like the under surface of M. semperi, excepting that
they are blacker, the discocellular veinlets are defined by metallic
blue instead of green spots, and the gold and green on the external
area is much more extended ; body below black, the legs and sides
of venter spotted with metallic blue spots. Expanse of wings 48
millim.

A single example only of this charming novelty was captured by
Mrs. Pryer, to whom (at her husband’s request) [I have dedicated
it.

The female only was previously known to us from Silhet and
“FE. India” ; the male now sent is very like that sex of S. auro-
grisea, but the abdomen is more decidedly banded with black ; the
abdominal half only of the secondaries is ochreous and the primaries
below are more distinctly veined with whitish.

The following appears to me to be a new genus of Nycteolide;
the male, from Borneo, has been for some years in the Museum
collecticn.

NYCTEOLID2.

SIGLOPHORA, n. gen.

Allied to Chandica, primaries with nearly straight costa, slightly
arched external margin and more strongly arched inner margin; a deep
longitudinal groove behind the costal vein on the under surface ;
subcostal with four ordinary branches, the two last emitted from a
long footstalk; the fifth branch emitted from the end of the cell
close to the upper radial, the lower radial emitted near the third
median and therefore looking like a fourth median branch: secondaries
rather short, deeply excised in the male on the radial interspaces,
merely angulated in the female; costal vein united to the subcostal

124 MK. A. G. BUTLER ON [ Feb. 16,

close to the base, separating from it at about the middle of the
discoidal cell and running thence to apex ; subcostal emitting two
branches from the anterior angle of the cell; discocellular weak, in-
arched; radial emitted at the inferior angle of the cell; second and
third median branches emitted from a long footstalk near to the radial:
body robust, similar to that of Chandica; palpi long, thick, and
compressed ; antennz, long, thick, simple; legs rather thick, the
middle tibize armed with two unequal spurs, the inner ones very
long ; posterior tibiee with four spurs. Type S. della.

SIGLOPHORA BELLA, n. sp. (Plate VI. fig. 2.)

Basal three-sevenths of primaries bright lemon-yellow, ornamented
by little irregular undulated lines and rings of blackish brown and
bounded externally by a dark imperfect line; a costal patch
beyond this area of the same colour and crossed by dark brown
irregular lines; remainder of wing vinous brown in the male, rust-
red in the female, varied by a few inconspicuous darker spots; a
deeply dentated submarginal line of yellow—indistinct in the male,
but sharply defined and partly bounded internally by black spots
in the female; fringe vinous, sericeous, spotted with grey:
secondaries with the basal half ( ¢ ) to third ( Q ) sericeous semitrans-
parent white, tinted externally with yellow and bounded by a badly
defined reddish band ; remainder of wing vinous grey; fringe with
a pale basal line: thorax bright yellow, varied with rust-red
markings: abdomen bright rust-red, with a yellow spot in the
centre of the basal segment, in the male specimen before me the
sides and margins of the segments are pearly whitish (possibly
owing to abrasion) and the anal tuft is blackish; on the under
surface the defined markings have all disappeared; the yellow
portions of the wings are softened down and the remaining area is
grey, a reddish band separating the yellow from the grey areas:
body below pearly white; palpi and fore tibize yellowish, banded
with vinous grey. Expanse of wings, ¢ 24, 2 23 millim.

AGNIDRA CARNFA, n. sp. (Plate VI. fig. 3.)

3. Sericeous pale brownish flesh-colour, sparsely irrorated with
blackish atoms, which are most abundant on the outer half of the
secondaries: primaries crossed by two very indistinct oblique
darker lines—the first before the middle, irregular, almost }-shaped,
the second regular, discal, more oblique, elbowed below apex; a
submarginal series of rosy spots on the veins: secondaries with two
whitish stigmata on the discocellulars; under surface rosy flesh-
coloured, veins ochraceous; wings sprinkled with black atoms;
primaries crossed by an oblique grey discal stripe, which is vaguely
continued by the black atoms across the secondaries ; fore tibice

CALLOPISTRIID.

I have waded laboriously through Walker’s long paper on the
Lepidoptera of Sarawak in the ‘Journal of the Linnean Society’
without being able to identify the three following species with
certainty ; the first, however, is probably his Hutelia? consentanea,
and therefore I so name it, although it is not a Hutelia but belongs
to a new genus allied to Hyperdasys.

PacHYDASYS, n. gen.

Primaries with straight costa, rectangular apex, and obtusely
angulated outer margin; palpi broad, obliquely ascending, com-
pressed, terminal joint short; antenne of male subserrate, fasci-
culated: all the femora and tibize and the tarsi of the hind legs
very broadly fringed and clothed with coarse hair-scales.

PLATYDASYS, n. gen.

Allied to the preceding genus and to Cotanda ; the wings of the
same form as in Dissolophus; the antenne most like those of
Cotanda but thicker, the femora and tibiz of all the legs and the
tarsi of the middle and hind pairs very densely clothed with coarse
hair-scales. Type P. pryeri.

PLATYDASYS PRYERI, n. sp. (Plate VI. fig. 6.)

Sepia-brown with faint roseate reflections; the primaries with
black and white lines and spots almost exactly as in the European
Methorasa latreillei; but the reniform spot is larger and more
indented in front, and the pink hastate spot immediately beyond the
sinuous black-edged white discal line and situated upon the upper
radial vein is much less prominent, so that it is scarcely distinguishable
from the remaining portion of the pale stripe bounding the external
edge of the disca! line. Expanse of wings 34 millim.

do, Sarawak; 2, Labuan. In coll. B.M.

A fragment of the female was obtained by Mr. Pryer in Sanda-
kan. This species should be among the insects described by
Walker ; but, if so, the description is not good enough to render its
identification possible.

Pa@ciLoGRAMMA, 0. gen.

Nearest to Gnamptocera, but in the pied character of its markings
very dissimilar, superficially, from any of the allied genera; antennze
normal in character, with short sparse ciliations ; palpi broad,
compressed, curved obliquely upwards, with short terminal joint ;
collar and tegule ample ; metathorax with prominent central crest ;
basal segment of abdomen probably tufted; legs long, the front
tibiz broad, the external edge being densely fringed with coarse
scales; femora of middle pair of legs flattened and grooved, the
tibiz densely clothed with hair and with two long terminal spurs ;
posterior legs almost naked, the tibize with the usual spurs. Type
P. picata.

Pa@cILOGRAMMA PICATUM, n. sp. (Plate VI. fig. 4.)

Primaries above sepia-brown, spotted and streaked with black,
the internal area whity brown ; base white, marked with two black
spots, an oblique bisinuated white stripe from the base of the costa
to an oblique white band across the basal two-fifths of the wing,
the latter band is traversed by a black line and is angulated at its
costal extremity ; an oblique white streak from the apex, interrupted
by the reniform spot, which is white, oval, and encloses two unequal
black spots, and the postmedian stripe, which is white, internally
edged with black, zigzag and very irregular, a slightly sinuous
white submarginal stripe, connected on the second median interspace
by a white spot, with a marginal series of internally white-edged
black dashes ; fringe whitish, spotted with grey ;: secondaries grey,
with diffused darker external border : head and collar blackish, partly

white-edged ; mesothorax buff, speckled with black; tegule
and metathorax white, spotted and speckled with black ; abdomen
whitish with grey dorsal spots: primaries below smoky grev, with
dull white inner margin; costa partly whitish ; an indistinct trans-
verse dark postmedian stripe and a subapical pure white spot :
secondaries whitish irrorated with grey scales; a black crescent at
end of cell followed by an arched discal grey stripe and a diffused
grey external belt which tapers towards anal angle; body below

SICULODIDE,
DurpDARA OVIFERA, n. sp. (Plate VI. fig. 7.)

Nearest to D. fenestrina, but differing from all the named forms
of the genus in its grey coloration above and in having an oblique
oval hyaline spot near the base of the first median interspace of the
primaries ; the outer half of the fringe of the secondaries is white ;
the primaries below are almost wholly glaucous grey, with white
internal border, and in the secondaries the costa and veins are
greyish ; the palpi are even longer than in D. plagifera, and are
whitish internally and along their inferior margins. Expanse of
wings 28 millim.

Mr. Meyrick says (Trans. Ent. Soc. 1887, p. 185) that “ Microsca
plagifera is a variety of Striglina myrtea, Drury (=fenestrina, Feld.,
and fenestrata, Gn.), with the spot (which varies very much and is
sometimes absent) unusually large. With every wish not to admit
too many species, I cannot conceive that Mr. Meyrick is correct in
this assertion ; for, however much a spot on the wing may vary in
size and shape, it appears highly improbable that the palpi would
follow suit, aud assuredly there is little resemblance between the
palpi of D. fenestrina and D. plagifera (which I described as a
Microsca). Our example of D. fenestrina is a female, and so far as
can be judged from the type of D. plagifera, in which the frenulum

130 MR. A. G. BUTLER ON [Feb. 16,

on one side is concealed and on the other broken, the latter is of the
same sex ; it has the last joint of the palpi much more slender and
of nearly twice the length of that of D. fenestrina.

When it is proved beyond question, by carefnl breeding, that
dissimilar forms are varieties of one and the same species, the sooner
they are put together the better; but this guesswork, especially
when concealed under the guise of an authoritative declaration, is a
positive hindrance to the acquirement of accurate knowledge. In
many cases where Mr. Meyrick has stated his conviction that a long
series of described forms belong to one variable species, he has been
subsequently obliged to alter his opinion; surely he cannot claim
that his first action advanced science, since he must know of a truth
that it only retarded it.

DuRDARA ROBUSTA.
Durdara robusta, Warren, in ltt.

The type of Mr. Warren’s unpublished description is from Sarawak ;
it is just possible that Walker may have described it as an Anisodes
or a Capnodes in his Supplement, or in one of the papers published
in the Linnean Journal; but I cannot venture to attempt its identi-
fication.

PHARAMBARA VINOSA, n. sp. (Plate VI. fig. 8.)

Pale vinous-brown; wings reticulated with darker brown: pri-
maries crossed by six imperfect darker bands, the outer edges of
which, and the inner edge of tlie third one, are defined by blackish
lines; the fourth and fifth lines are inarched towards the costa; the
sixth, which is submarginal, is abbreviated and cuts off the apical
half of the external border ; on the secondaries there are about three
black-edged, ill-defined, abbreviated bands from the costa, the central
one is acutely elbowed and bounded on each side near the centre of
the wing by a hyaline, subquadrate, white spot ; on the under surface
all the markings are more sharply defined, and on the primaries is a
subcostal, basal, shining, pearly tuft covering the base of the frenulum.
Expanse of wings 26 millim.

A single male example.

The species does not appear to be very closely allied to any
named form.

URAPTERYGID.
SYNGONORTHUS, n. gen.

Allied to Gonorthus : of the same form and with similar neuration ;
but the male antennz much shorter and with very short fine ciliations
instead of being strongly pectinated.

SYNGONORTHUS SUBPUNCTATUS, nu. sp. (Plate VI. fig. 9.)

Pale creamy stramineous, slightly sericeous; the wings irrorated
with greyish argillaceous; the primaries crossed by two nearly
parallel, straight, transverse stripes of the same colour; outer margin
and fringe forming a third stripe rather more ferruginous in tint ;

1892. ] LEPIDOPTERA FROM SANDAKAN. 131

costal margiu narrowly ochraceous, speckled with blackish : second-
aries with only a discocellular spot to represent the inner stripe of
the primaries, but with a well-defined subangulated outer stripe from
outer fourth of costa to inner margin, close to anal angle ; marginal
stripe blacker than onthe primaries: head and collar rufous-brownish :
wings below without irrorations, but crossed by a straight discal
series of blackish spots on the veins; primaries tinted with pink,
with a transverse blackish dash on the discocellulars ;_pectus whitish.
Expanse of wings 38 millim.

This very distinct species is unfortuuately only represented by one
imperfect specimen ; it is, however, so unlike anything else that I
have seen or of which I can find a description, that I have no
hesitation in naming it.

Basal area of wings white, speckled with black and transversely

with white and crossed to near costa by white-edged, zigzag, dark
brown stripes, three on the primaries and two on the secondaries,
also by a submarginal stripe, slightly waved on the primaries, but
distinctly zigzag on the secondaries, the third and sixth angles filled
in so as to form blackish, more or less triangular spots ; a slender,
slightly zigzag, black marginal line; fringe, excepting along the
abdominal margin of the secondaries, very short: head and collar
blackish ; thorax white, speckled with black; abdomen wanting:
under surface pale pearl-grey ; the disk of the wings crossed by two
subparallel darker grey bands, enclosing a white belt; the outer
band angulated on the primaries ; legs silvery whitish. Expanse of

[Received January. 19, 1892.]

Two further collections received from Mr. Jayakar in 1891
enable me to supplement the list of Muscat Fishes with the names
of seventeen species, of which one (His¢iopterus typus) belongs to a
genus previously unknown from the Indian Ocean.

2. Hisrioprerus typus, Schleg.

This fish is on record from Japan only; but a fine specimen from
Duke-of-York Island is preserved in the British Museum. The
genus Histiopterus is an important addition to the fauna of the
Indian Ocean, and it seems surprising that so striking a form should
have hitherto escaped notice on the coasts of India and Ceylon,
where it will no doubt be eventually found.

Length of head a little more than one fourth of the total (with-
out caudal) ; diameter of the eye a little greater than the length of
the snout, two sevenths the length of the head. Pectoral three
fourths the length of the head. Depth of the body thrice and one
third in the total length (without caudal). Caudal deeply forked.
Upper half of body greyish olive, lower half yellow; four rather
indistinct dark lines along each side of the body, the uppermost
running along the lateral line; a black spot in the upper axillar
portion of the pectoral.

Total length 250 millim.

A single specimen.

This species is very nearly related to the Atlantic and Mediter-
ranean Box vulgaris, from which it differs in the deeper body, the
somewhat larger scales, and the slightly different number of rays.
The fin-formula and the axillar spot differentiate it from Cuvier
and Valenciennes’s 2. salpoides, stated to be from the Indian Ocean.

if I am right in not separating the Pacific 7. macropterus from the
Albacore, it must be admitted that both the true Tunny and the
Albacore roam over the Atlantic, Indian, and Pacific Oceans.

In the Indian Ocean T. thynnus must be by far the rarer of the

total absence of teeth, the still greater projection of the lower jaw,
and the very small extent of the scaleless portion of the breast.
The differences are, however, ascribable to age; and I have not the

3. Descriptions of Three new Species of Earthworms. By
W. Braxtanp Bennam, D.Sc. (Lond.),- Aldrichian
Demonstrator in Anatomy in the University of

Oxford’.
[Received February 1, 1892.]

(Plates VII. & VIII.)

In July of last year (1891) I received from Professor Jeffrey Bell
three bottles containing Earthworms which had been presented to
the National Collection. With the permission of Dr. Giinther, I
was allowed to make an examination of these specimens, and to
treat them in any way necessary for their identification.

I wish to express my thanks to Dr. Giinther for this privilege, and
to record my appreciation of Prof. Bell’s kindness in allowing me to
examine many Earthworms which from time to time have come into
his hands for identification.

The contents of the bottles were as follows :—

A. Three small worms [Plutellus perrieri, n. sp.| collected at
Masset, Queen Charlotte’s Island, British Columbia. Pre-
sented by the Rev. T. H. Keen.

B. A single specimen [Microcheta papillata, nu. sp.| from Port
Natal. Collected and presented by H. A. Spencer, Esq.

C. A single specimen [Microcheta belli, n. sp.| from East
London, Cape Colony. Collected and presented by H. A.
Spencer, Esq.

A. In the bottle from Queen Charlotte’s Island were three
worms, two mature and one apparently immature; the latter I cut
into a series of transverse sections after the examination of one of
the mature forms, under the impression that it belonged to the same

species as the other two, but I find that it is an Enchytreid, the
anatomy of which, however, I have not yet worked over.

Of the two other specimens one remains entire, and was returned
to the British Museum, the drawing of the external surface (Plate
VII. fig. 1) being taken from it; the second was partially cut into
sections—after being opened and examined—the anterior twenty
somites being cut sagittally, the posterior portion transversely.

The chief characters of the worm may be summed up as follows :-—

(1) The eight chete are isolated, though they are not all
equidistant.

(2) The clitellum is complete, and occupies somites xiil. to xviii.

(3) The male pores are on somite xviii.

(4) The nephridiopores alternate in position, one series being in
line with the cheetze ‘‘3,” the other with the chete “4.”

There are (5) one pair of testes in somite x.; (6) one pair of
sperm-sacs in somite xi.; and (7) four pairs of spermathece,
without diverticula, in somites vi., vii., viil., and ix.

(8) The cylindrical prostate lies in somite xviii.

(9) The gizzard occupies somite v.; there are no definite
cesophageal diverticula.

The Earthworm which appears to agree most clearly with this
diagnosis is Plutellus heteroporus * from Pennsylvania; but this worm,
according to Perrier’s description, presents two very striking anom-
alies, which do not occur in the present instance: (a) the nephridia
are entirely confined to one somite, z. e. the funnel does not perforate
the septum ; (4) the “ ovary ” is placed anteriorly to the testes.

But these two peculiarities are anomalous, not amongst Earthworms
only but amongst all the Oligocheta ; the post-septal position of the
nephridiostome is indeed totally at variance with the arrangement met
with throughout the whole group of Chetopoda ; hence, we must look
with very great suspicion on these supposed characters, and indeed
Perrier himself, in writing of the presumed “ovary” in the tenth
somite, recognizes its abnormal position and expresses himself, not
only with great caution, but also with a good deal of doubt—* Mais
nous devons dire qu’a cet égard notre conviction est loin d’étre aussi
complete qu’en ce qui concerne les testicules.”

Most zoologists working on this group have thrown doubts on the
accuracy of these supposed facts, and this without impugning the
carefulness of M. Perrier, for he had two specimens only, and these,
having lain in spirit for 50 years and more, were in a very bad
condition of preservation; moreover, his statements were drawn from
observations on the dissected specimens, which are not so likely to
be correct as those obtained from examination of serial sections.

We must then remove these two characteristics from the diagnosis
of the genus Plutellus, and thereby we bring the worm into accord
with what has become regarded as the normal condition of things.

I believe the worm which forms the subject of this communication

1 Hd. Perrier, Arch. de Zool. Expér. ii. 1873.

138 DR. W. B. BENHAM ON [Feb. 16,

belongs to Perrier’s genus, and name it after that zoologist. I shall
reserve certain histological points for later consideration.

PLUTELLUS PERRIERI, ll. Sp.

It has a length of 2 inches (50 mm.) and a comparatively great
diameter—namely a little more than 1 inch (4 mm.); the length of
the clitellum is 4 mm., and the distance from its anterior margin to
the tip of the prostomium is 7 mm.’ There are 126 somites in the
specimen which remains uninjured ; they are all well marked and
are only obscurely annulated. The two extremities of the worm are
rounded, obtuse, and not noticeably attenuated, and at the posterior
extremity the body is slightly dilated.

The prostomium is distinct and completely dovetailed into the
buccal somite, as it is in P. heteroporus.

The clitellum, when the worm is fully developed, extends all round
the somites xiii. to xviii., with the exception of the median ventral
region of the last somite and a short portion of the first somite.

The intersegmental grooves are entirely obliterated and the anterior
and posterior boundaries are very sharply defined. In the specimen
dissected, where the clitellum was not so fully developed, the
ventral surface of the somites was less glandular and the grooves less
obliterated than in the entire specimen, and a pair of papille exist on
somite xvill. between the cheetee “1” and ‘*2.”’ In the fully matured
form, the glandular modification of this somite extends ventrally so as
to become continuous with these papillze, which are then no longer
evident.

[In P. heteroporus the clitellum is also complete, occupying
somites xiv. to xvil., but overlapping the anterior part of somite xviii. |

The chete, eight in number, are isolated ; the ventralmost—con-
stituting the series of chatz “1’’—on each side is close to the
middle line ; if the space between “ 1” and “2” be taken as the unit,
represented by S, the space between the ventral cheete of the two
sides is 2S, that between the second and third is 13S, that between
«3” and “4”’ is 2S, and the dorsal area, between the dorsalmost
chete of the two sides, is 5S; the chete “4” lie dorsally
(Plate VII. figs. 2and 4). Posteriorly the space “ 1-2” is slightly
greater than it is anteriorly ; and anteriorly to the clitellum, space
1-1 is less than it is posteriorly.

[In P. heteroporus the cheetz are equidistant, but posteriorly the
dorsal and ventral spaces are a little greater than the lateral spaces,
and spaces 1—2 and 3-4 are a little less than anteriorly. |

The cheetze themselves are of the usual lumbricid form, without
ornamentations ; there are no modified, copulatory chzetz of any sort.

The nephridiopores are not visible externally in my specimens,
which are very well preserved, and the segments probably a good
deal closer together than in life; but I find from my longitudinal
sections that they have the following arrangement (Plate VII. figs. 2
& 4) :—The first pore lies on the anterior margin of somite iii., and,

1 These figures for P. heteroporus are 15 cm. as length of body, 6 mm. as
length of clitellum, and 4 mm. as its distance from the extremity of the body.

1892.] NEW SPECIES OF EARTHWORMS. 139

like the pore of the next somite, is in line with the cheetz “4”; the
pores in somites v., vii., ix., xi., xiii., xv., &c. are in line with cheetz
**3”; those of the even-numbered somites are in line with cheetee “4”;
but in the case of somites vi., viii., x., xii., I did not actually see the
pores, as the dorsal body-wall in this region of the body had been
injured in dissecting the worm, but there is no pore in either of
these somites in line with either of the other cheete.

[In P. heteroporus, the nephridiopores of somites iil., iv., v., vi. are
in line with the third chzetze, those of vil., ix., xi., &c. with the fourth
cheetze, and those of vili., x., xii., &c. with the second cheetee, with
some divergence from regularity in certain somites. |

The male pores are on somite xviil., just between the first and
second cheete ; but in the immature specimen, as I have mentioned,
there is a pair of papille in this position, which carry the pores ;
the papille in the fully developed individual being continuous with
the rest of the glandular modification of the clitellum.

With regard to P. heteroporus, Perrier states (p. 255) “il nous
semble que les orifices males étaient accompagnés chacun d’une
papille en avant et en arriére,”’ but owing to the state of preservation
of the worm he was uncertain on the point. The figure (Plate VII.
fig. 1) which accompanies the present paper might suggest these
papillee, but the slight pit represented between somites xvii. and xviii.
is not the male pore, which lies on the slight papilla on somite xviii.

I was unable to see the pores in somite x. which Perrier regarded
as those of his “‘ oviducts ”; they, in fact, do not exist in the present
worm. With regard to these pores, his figures are not in agreement
with one another.

The spermathecal pores (which are in line with chete “‘ 2,” at the
anterior margin of somites vi. to ix.) and oviducal pores (on somite
xiv.) are not visible in surface view.

There appear to be no dorsal pores; this is one of the few points
in which my specimen differs from P. heteroporus.

Internal Anatomy.

The septa bounding posteriorly each of the somites v. to xi. are
considerably pouched centrally, so that the organs in these somites
are carried backwards in such a way that they appear to occupy a
more posterior position than they actually have ; the septa behind the
somites viii. to xii. are slightly stronger than the others (Plate VII.
fig. 3).

The nephridia conform to the usual type; the coiled tube pre-
senting the three regions which I have described’ in those of
Lumbricus and which appear to he pretty generally present in
“ meganephric ” Earthworms.

The muscular region or “ bladder” is very large, and differs in
size in the two series of nephridia. The funnel has the normal
structure and position—. e. it is preeseptal.

The genital organs have the following arrangement, as determined

’

1 “The Nephridium of Lwmbricus,” Quart. Journ. Micr. Sci. xxxii. p. 294.

140 DR. W. B. BENHAM ON [Feb. 16,

by dissection, controlled by examination of a series of longitudinal
sections.

A single pair of testes lies in somite x. enclosed with the ciliated
rosettes in a special sac, continuous below the gut from side to side,
and with the sperm-sacs in the following somite; of the latter
there is but one pair in the specimen examined—which, it must be
remembered, may not have been guite mature ; they do not extend
into either of the neighbouring somites, but are entirely contained
in somite xi. (Plate VII. fig. 3, sp. sac).

[In P. heteroporus, Perrier places the “‘ testicules,” 7. e. sperm-
sacs, in somite x1i.]

The sperm-ducts were traceable to somite xviii., in which lies a
pair of prostates (Prost., fig. 3). Each prostate is cylindrical, and
curved upwards, so that the free end, which is slightly recurved, lies
above the gut, the ventral end is continued as a narrow muscular
duct (gen, d.) along the body-wall to the external pore; this
“ venital”’ or penial duct receives the sperm-duct immediately after
its origin from the glandular portion of the organ.

The prostates are entirely confined to their somite, and their
histological structure agrees with that of Pericheta and other worms.

[In P. heteroporus the gland is several times bent, as in
Acanthodrilus, and is wider ventrally, where the penial duct
originates. |

A pair of ovaries lies in somite xiii. (Plate VII. fig. 3, ov.), and the
oviducts have the usual position. The gonad is fairly large, and in
section is seen to occupy the greater part of the cavity of the
somite, extending upwards and outwards on each side.

I may again remark that I find no structures in somite x. which
would answer to Perrier’s “ ovaries’’; indeed, he himself felt uncer-
tain as to the correctness of his interpretation of these grape-like
glands, and suggested that they might be an anterior pair of
“ testicules ’’ (sperm-sacs)} He remarks, however, that their
structure differs from that of the sperm-sacs in somite xii. and
states (on p. 259): ‘‘Ce sont des grosses granulations réfringentes,
groupées de maniére a constituer des sphéres, au centre desquelles
nous avons vu souvent une apparence de vésicule transparente et des
taches germinatives,” but adds his doubt on the matter of interpre-
tation which I have quoted above; there is, indeed, nothing in his
description which leads me to believe that these structures are
ovaries, and when he mentions that a large funnel, like that of the
sperm-duct, lies below this organ—. e. in the position in which I
find the ciliated rosettes—I think we may conclude that these organs,
whatever they may be, are o¢ ovaries.

It is possible, indeed, that they are masses of young stages in the
development of spermatozoa, which have become free in this somite,
or a portion of the sperm-sac, which after rupture of the septa
might come to lie here, or again cysts of AZonocystis.

As to the organs which he described as ‘‘testicules’’ in somite
xii., there is little doubt but that he was dealing with the sperm-
sacs, for he found “spermatiques filaments” attached to central

1892. | NEW SPECIES OF EARTHWORMS. 141

spheres, and younger stages in the development of spermatozoa,
though their position in this somite is rather diffcult to explain, except
on the idea that the septa, here delicate, may have become ruptured
or displaced in dissection. But Perrier was a very careful dissector,
and he had had great experience in the dissection of Harthworms,
so that it is scarcely justifiable to suggest a mistake in the matter.

In P. perrieri there are four pairs of spermathecze lying in somites
vi. to ix.; each is an ovoid sac, without any distinct neck or duct and
without a diverticulum (Plate VII. fig. 3, spth.). Each sac opens
at the anterior margin of its somite—practically intersegmentally—
in a line with the second chete.

[In P. heteroporus there are five pairs, the additional pair being
in somite v.; each sac has a diverticulum. ]

I may add that in the genus Pericheta we find species with and
species without diverticula to the spermathece.

In the alimentary tract the position of the gizzard is to be noted ;
it lies, as seen in sections, entirely in somite v., though its hinder
extremity is carried back to the level of somite ix. (Plate VII.
fig. 3, giz.).

The following region of the gut, as far back as somite xvi., has
very vascular walls, which are considerably folded (Plate VII. fig. 3).
But there are no definite ‘pouches’ or diverticula, though the
general structure recalls that of calciferous glands ; and I find in the
hinder somites crystalline bodies, resembling those of carbonate of
lime present in the glands of Zumbricus, but there is no effervescence
on the application of acetic acid. This vascular region of the gut is
not so extensive as it appears on paper, for the cavities of somites
vi., vil., vill. are exceedingly short, the septa being almost in contact
centrally.

The thin-walled intestine commences in somite xvii. or xviii. and
is very wide, occupying a considerable extent of the body-cavity ;
there is no typhlosole (Plate VII. fig. 4).

[In P. heteroporus the gizzard is in somite vii. ; there are three
pairs of reniform diverticula, with short ducts, in somites x., xi., xii. ]

B. MicrocH2TA PAPILLATA, 0. sp.

We are acquainted with only two species’ of this genus, which
was instituted by Beddard’* for a worm originally described by Rapp
under the name of ‘ Lumbricus microcheta,’ collected in Cape
Colony. Mr. Beddard named the species M. rappi, and it received
a description at my hands*® almost simultaneously with that
published by him. I described the second species, from Natal,
under the name of M. beddardi*. In a recent paper’ I have pointed

1 After the MS. of this paper had left my hands, I received from Dr. D.

torischen Hofmuseums,” published in the ‘Annalen d. k,-k. Nat. Hofmuseums,’
Wien, 1891, Bd. vi. Heft. 3 & 4. Herein he describes a third species,
M. benhami.

out that the numbering of the somites, as it stands in my description,
requires some alteration, and Beddard*_has likewise made certain
corrections in regard to the interpretation of certain organs, which
have become necessary from the advance in our knowledge of the
anatomy of the group’. I here give a figure (Plate VIII. fig. 8) of
the anterior end of M. beddardi, in illustration of my remarks on
the alteration of numbering of this somite.

Microcheta papillata has a length of 10 inches and a breadth
of half an inch; it is thus smaller than either of the two previously
known species. As to its colour, I am unable to speak, for, as is
so generally the case, it has evidently been considerably changed by
the spirit.

The prostemium (Plate VII. fig. 5) is, as in M. beddardi, broad and
marked by longitudinal grooves, which extend into the first somite
(cf. Plate VII. fig. 6, representing M. belli); this somite is similarly
grooved on the ventral surface. The following somites are bi- or
tri-annulated, but the grooves between the annuli are in some cases
almost as marked as those between the somites, so much so, indeed,
that in fixing the position of the various external characters I at first
reckoned the annuli as somites. The first three somites are not
annulated ; the fourth to the ninth inclusive are bi-annulated
(a, 6), the grooves between the annuli being very deep; posteriorly
the somites are not so noticeably annulated. This same well-marked
annulation of the somites exists, as I have pointed out and figured,
in M. rappi.

The chete, however, serve to define the somites, and, as in the
other two species, are in four couples per somite, the individuals of a
couple being close together; the outer couple is quite lateral in
position, being about midway between the dorsal and ventral median
lines ; whilst the inner couples are latero-ventral. The interspace
between the outer and inner couples is about equal to the space
between the two inner couples. The chzetz themselves are very
small, and in the anterior somites, indeed, I had to make use of
Zeiss’s B, as a hand-lens, in order to see them; they commence in
somite iii. It might be suggested that the first somite is biannulate,
but in M. delli (Plate VII. fig. 6) the cheetze occur in the second
somite, which is in other respects similar to the second ring of the
present species. The four species exhibit an interesting series of
stages in “cephalization.” In IV. belli the first and second somites
are distinct, the cheetee being present on the latter. In M. beddardi
these somites are not distinctly marked off from one another (Plate
VIII. fig. 8), and the apparent first somite carries chzete in its
hinder part; in MW. papillata, though the somites are distinct, the
cheetze are absent on the second: in IZ. rappi the two somites are
with difficulty distinguishable from one another; the first annulus

? Rosa points out this necessary correction in the paper just referred to, on
p. 384

1892.] NEW SPECIES OF EARTHWORMS. 143

probably is somite i., and the next two annuli belong to somite ii.
(see pl. xv. fig. 1 of my paper, loc. czé.).

The cheetz of both the new species differ from those of the
previous species in the presence of an “ ornamentation,” similar to
that of the chete# in Rhinodrilus', and consisting of longitudinal
rows of obliquely transverse ridges’.

The clitellum is evidently not fully developed, but the interseg-
mental grooves on the dorsal surface of somites xix. to Xxxvill.
are partially obliterated (this area includes the 26th to 35th annuli).
Along each side of the vody there is a very pronounced latero-ventral
ridge extending across somites xvi. to xx., the body being here
flattened, though probably the appearance, as represented in the
figure (Plate VII. fig. 5, é.p.), is less marked during life. This
ridge is glandular and appears to correspond with the structures
known as the ‘‘tubercula pubertatis ” in Lumbricus, Allolobophora,
Rhinodrilus, &c.

By teasing up the body-wall, and by the examination of sections, I
find the clitellar cells to occur over a much wider area than that
represented by the above numbers, viz. as far forwards as somite x.,
so that we may, I think, conclude that the clitellum, when fully
developed, covers the somites x. to xxx. This agrees closely with
the extent of the same organ in IZ. rappi as described by Beddard ;
in the specimen examined by myself it occupied somites xiv. to
xxvi2 In M. beddardi the clitellum is less extensive, covering
somites xi. to xxiii.; but in neither of these species did I find the
limits well defined.

Although I did not observe, when I was engaged upon the previous
species, anything like tubercula pubertatis, yet I figured for M.
rappi * the ventral edges of the clitellum as being well marked and
thickened ; a re-examination, too, of specimens of M. beddardi re-
veals, though in a very indistinct manner, owing to their very poor
condition, a band along each side of the clitellum, which is no doubt
of the same nature.

The nephridiopores are, as in the other two species, very distinct
even along the clitellum; they are placed in front of the outer
cheetz, i. e. along the sides of the body, the first nephridiopore
occurring in somite iii. There are no dorsal pores, nor could I detect
any of the generative apertures. But on either side of each of the
somites x. and xxili., that is on the somites which carry the 8th and
21st nephridiopores respectively, occupying the position of the inner
cheetze, is a rounded papilla (Plate VII. fig. 5, cp., ep’.), slightly pitted

increase the numbers given in my description of M. rappi by one, as the
apparent first somite is in all probability somite i. and ii., the cheete of somite

at the tip; and projecting from this pit is a smaller whitish papilla
provided at its apex with a minute pore (Plate VII. fig. 7).

I expected, at first sight, that the hinder pair of the papille
would be in connection with the sperm-ducts, but no such relation
exists. Each of the four papille is represented internally by a
rounded or kidney-shaped swelling (Plate VIII. fig. 9), from the
centre of which (or from the hilum as the case may be) there passes
to the body-wall a bundle of fibres (m). These are muscle-fibres
and surround a “ cheetophore” or sac containing the chet, which
replace the ordinary ventral cheetz, from which they differ only in
their greater length.

The papilla itself has the following structure (which is closely
similar to that of the next species, of which a figure is appended
(Plate VIII. figs. 10, 11): the pore at the apex of the inner papilla
(pap.) leads into a sec lined by columnar cells (ep.) forming a definite
epithelium ; the lumen of the sac extends in an irregular way for
some distance all round the aperture, and its epithelium is, at places,”
considerably folded. Outside the epithelium are numerous bundles
of muscle-fibres (mus.), some radially arranged, some circularly, and
some longitudinally (as seen in a transverse section of the body-wall
passing through the papilla). These fibres can be traced into the
muscular layers of the body-wall, from which they are evidently
derived by its invagination. Outside the muscular coat—though
not separated from it by any marked line such as the figure
suggests—is a thick coat of clitellar cells arranged in groups (fig.
11, gl.). Blood-vessels ramify between the groups and amongst the
muscle-bundles. Surrounding the whole is a layer of flattened
coelomic epithelial cells (co.ep.), which dips down between the
groups of clitellar cells. The muscle-fibres are found only near the
aperture in that part of the organ which forms the external papilla ;
in the remainder of the gland the clitellar cells abut immediately
upon the epithelial cells.

There is a remarkable resemblance in structure between this organ
—which is evidently copulatory in function and capable of slight
eversion—and the prostates (or atria) of Pericheta, Acanthodrilus,
Trigaster, &c.; the epithelium, however, is more definitely marked
off from the gland-cells than in these, and recalls, rather, the pros-
tates of Pontodrilus; or if we compare the structure of the organ
near its pore with the atrium of Moniligaster we shall see a still
greater resemblance, except that in the latter genus there is, ac-
cording to Beddard’s description’, no membranous ccelomic epi-
thelium, for the “ clitellar cells” represent this layer.

Amongst the families Rhinodrilide, Geoscolecide, and Lumbri-
cide, a “ prostate ” is not usually recognized as being present, but
in several genera there is a more or less conspicuous swelling of
the body-wall, which is perforated by the sperm-duct in its passage
to the exterior. In Geoscolex, Brachydrilus, Criodrilus, and Calli-
drilus such structures exist; of the histology of these, however,

1 Q. J. M. Se. xxix. pp. 119 &e. pl. xii. fig, 11.

1892.] NEW SPECIES OF EARTHWORMS. 145

records are scanty. In Criodrilus I mention’, briefly, the ‘‘ hemi-
spherical gland, which may be called a prostate,” and which ‘‘ con-
sists of cells similar to those forming the epidermis of the clitellum
and quite continuous with them; the gland appears to be formed
only by a hemispherical thickening of the epidermis over this area.”
Rosa * refers to this organ as “atrium.” In the case of Callidrilus,
Michaelsen* states that this “doubtful prostate” consists of small
granular cells, with indistinct boundaries, the nuclei sometimes being
scarcely recognizable ; in the same place he describes—though very
briefly—structures of the same nature as those in Mier. papillata
as occurring in Kynotus madagascariensis; to which I shall refer
later on in this paper.

The nature of the organ in Geoscoler is unknown. But Micro-
cheta (and probably Kynotus) differs from the rest in that this
gland is entirely independent of the sperm-duct ; whereas in pros-
tatiferous worms (that is, those of the families Cryptodrilide,
- Perichetide, Acanthodrilide, Eudrilide, &c.) this gland is always
in connection with the sperm-duct, or in its immediate neighbourhood ;
moreover, it is tubular in general character and is apparently a more
efficient organ of copulation than in these other cases.

We are in ignorance of the real function of the prostate or of the
‘genital duct’ in these prostatiferous worms; but there is, pro-
bably, a protrusion of the muscular duct during copulation, and an
insertion thereof into the spermatheca, as there is undoubtedly
in such forms as the Tubificide: but in the case of Microcheta
such a penial function is impossible, for there is no sac into
which such a papilla could be inserted; it probably, however,
serves as a sucker. The small papilla in the terminal pit of the
larger one, the muscular arrangements, and the folded cavity suggest
such a sucking-organ ; and, no doubt, the copulating cheetz serve to
aid this apparatus in holding on to another worm *.

It is not necessary to think that this sucking-apparatus in Micro-
cheta is the forerunner of the prostates with their protrusible duct,
though it is quite possible that this latter organ may have arisen
from some such apparatus as is present in Brachydrilus, Geoscolex,
&e., where the “sucker” is perforated by the sperm-duct. During
copulation in Lumbricus, &c., the ventral surface of the clitellum
itself, bounded by the tubercula pubertatis, very probably acts as
a sucker; here in Microcheta a more specialized apparatus, on

+ Rosa describes (Ann. d. k. k. Natur. Hofmus. 1891) certain glandular
bodies in M. benhami (in somites xi. to xxviii.) which appear to have a some-
what similar structure; but he mentions no external papillz: he compares
them with the “ pyriform glands” of Urobenus and Urocheta, and suggests, as
I have done, their possible connection with the prostates of other wornis; and
his species forms an interesting link between the arrangement in Urobenus and
M. papillata, though the structures in J. benhami do not appear to have any
copulatory functions.

definite spots, has taken the place of, or is developed in addition to,
this clitellar sucking arrangement.

It is very generally believed that in Lwmbricus herculeus, Savigny
(L. terrestris, auct.), a mucous band is developed around the bodies
of the two worms during the process of copulation: but, from my
own repeated observations of the act in Lumbricus, 1 can state, as
some of the older authors have stated, that such a band does not
exist. There is such a band in Allolobophora fetida and no doubt
in other species, but in Lumbricus the two worms are joined
together, and that pretty firmly, by the action of the tubercula
pubertatis, and no doubt by a certain amount of sucking-action,
exerted by the ventral region, not only of the clitellum, but also of
all that part of the body lying between that and the fifteenth somite,
which is converted into a groove by the action of a band of muscles
passing from one side to the other—the arched muscles '.

In worms, such as Pericheta and Acanthodrilus, &c., where the
clitellum is ‘“‘complete”? or nearly so, and where no tubercula
pubertatis exist, there is no evidence of any power of converting the
ventral surface of the body into an adhesive apparatus: and it is in
these forms that a (probably) protrusible penis—or muscular duct of
the prostate—exists. This organ has either (1) actually replaced the
adhesive arrangement such as exists in Lwméricus, in which case the
sucking-papillee, independent of the sperm-duct in Microcheta and
the (probably) similar apparatus around the male pore in Geoseolex,
Brachydrilus, Criodrilus, may represent stages in the process ; or
(2) the two modes of copulation may have arisen independently.

The Internal Anatomy.

In the arrangement of its internal organs M. papillata agrees
closely with that of the previous species.

The nephridia, though smaller, present the characteristic tuft
of coiled tubules at the end of a fairly large bladder; the “ fine
tube” ” presents the same peculiar branching and anastomoses that
I have described for M. rappi’.

The dorsal blood-vessel is doubled in the somites v., vi., Vil., Vill.,
and ix., and in the last somite is dilated to form a double heart-like
organ; in each case the two vessels unite at each end of the
somite to form a single tube perforating the septa; in M. rappi
this doubling occurs in the same somites, but in M. beddardi it is
limited to somites Vii., vill., and ix.

Large moniliform “ lateral hearts ”’ exist in the present species in
somites 1xX., X., Xi., and smaller ones in somites vil. and viil., as in
M. rappi.

With regard to the alimentary tract, the chief features to be noted
are (a) the gizzard, which appears to occupy somite vi., and (0) the
cesophageal diverticula or calciferous glands ; of these there is but

one pair in somite ix.—one somite anterior to that of M. rappt. In
M. beddardi, however, the gland is partly in somite ix. and partly
in somite x., occupying, as it were, an intermediate position between
that of the other two species.

The genital organs.—There are apparently three pairs of sperm-
sacs, but in reality only two pairs are present, each sac being con-
stricted into a larger anterior portion, and a small posterior and more
ventrally situated lobe. The two larger sacs (Plate VIII. fig. 13,
A, B) lie in somites x. and xi.; the posterior lobes, constricted by
the septa, lie in somites xi. aud xii. (C, D). There are no median
sacs.

The two pairs of ¢estes and of ciliated rosettes, which lie in somites
x. and xi., are enclosed in the larger portions of the sacs.

In M. rappi there is the same kind of subdivision of the sperm-
sacs, the anterior lobe, however, of each being the smaller and
containing the testes; they occupy (according to the amended
‘numbering of the somites) the same position as in the present
species.

The two sperm-ducts of one side unite in somite xii., but I was
unable to trace them onwards; they have no connection with either
of the copulatory apparatus mentioned above.

The spermathece have the same arrangement as in the other
species ; that is, a row of ten or twelve very small oval sacs on the
anterior margin of each side of somites xiii. and xiv.

In M. rappi there are fewer in each row, but four rows on each
side, and some of them are curved. Similar spermathecew exist in
Brachydrilus* and in Kynotus.

C. MicRocHATA BELLI, 0. sp.

This species agrees in its anatomy very closely with M. beddardi,
I name it after my friend Prof. Jeffrey Bell, who has enabled me to
examine and study a large number of Earthworms presented to the
National Collection *.

Its length is § inches and its diameter is ? inch.

It had apparently been allowed to become dry at some period
before it reached me, as the worm is much shrivelled, and a dark
brown, hardened, plate-like structure occupies the dorsal surface of
somites xilil, to xxi. and part of the next somite; this ‘“ saddle”
extends laterally as far as the nephridiopores, or line of the outer
chete. This brown area appears to represent the clitellum. Along
the lateral boundary of part of the clitellum is a broadish band, having
a glandular appearance, crossing the somites xv., XVl., Xvil., XVill.,
and part of xix. This recalls the twbercula pubertatis of the Lum-
bricide, and a similar structure is already known in Rhinodrilus
and Hormogaster, and Horst speaks of something of the sort in
Glyphidrilus®. On the ventral surface these segments, though dis-

tinctly marked off from the clitellum, are more sharply separated
from one another than is the case elsewhere in the body. The
histological structure of the tubercula is represented in Plate VIII.
fig. 14.

ena each side of somite xiii., between the outer and inner couples
of cheete, aud rather nearer to the former, is a copulatory papilla,
similar to those I have described above for M. papillata.

The nephridiopores and the oviducal pores have the usual positions ;
I could not detect any other apertures.

The cheete have the same arrangement and markings as in M.
papillata : they are longer than in that species and commence on the
second somite.

The annuli of the anterior somites are extremely well marked by
deep grooves (Plate VII. fig. 6). The first somite is simple; the
second is triannulated ; the third is biannulated ; somites iv. to ix.
(inclusive) are triannulated, the third annulus in each case being
very distinctly marked off; the tenth is biannulated ; the following
ones are bi- or triannulated, though the annuli are not so distinctly
separated.

Of the internal organs, one or two features are worthy of note.
Three septa are stronger than the others ; the first lies between somites
iv. and v., the second strong one lies in the middle of the somite
viii., the third in the middle of somite ix.

The csophageal glands are nipped by the septum between
somites ix. and x., as in Mf. beddardi. There is only one pair of
ciliated rosettes (and probably, therefore, of testes) in somite x. and
one pair of sperm-sacs in the same somite.

In M. beddardi, also, there is but a single pair of each of these
organs—the testes in somite x., the sperm-sacs in somite xi.

I traced the sperm-duct as far as somite xvi., where it enters the
muscles of the body-wall. But I have been unable to determine the
position of the external aperture ; for I did not wish to injure the
single specimen.

In M. rappi the spermducal pore lies in somite xx.; but I was
unable to find the pore in WM. beddardi, where, however, it has
probably the same position’.

The spermathece are eight in number, arranged in couples on
the anterior margin of each side of somites xii. and xili.; they are
larger than in M. papillata, though of the same shape. In number
and position they agree with the condition in M. beddardi.

The four species of Microcheta can thus be arranged in two
groups :—

I. M. rappi and MW. papillata have two pairs of testes, and
very numerous spermathece arranged in rows of several in a
row; the cesophageal glands lie wholly in one somite; the dorsal
vessel is doubled in each of the somites v. to ix.

Il, M. beddardi and IW. belli have but oue pair of testes; have
eight spermathece arranged in couples ; the wsophageal glands are

1 In M. benhami this pore is between somites xx. and xxi.

1892.] NEW SPECIES OF EARTHWORMS. 149

indented by a septum, so as to lie partially in two somites; the
dorsal vessel is doubled in three somites only.

Remarks on the genus Kynotus, Michaelsen.

Dr. Michaelsen has recently described two species of this new
genus which present certain anatomical features that are so unusual
as to deserve a reconsideration.

Kynotus madagascariensis’ and K. longus* both come from
Madagascar.

The description of them is very incomplete, both as regards ex-
ternal and internal anatomy, owing to the bad condition of the
specimens. These were not mature, and no clitellum was present.

The chete are absent in the anterior part of the body in the
first twenty-six “ segments” (Mich.), so that the correct interpre-
tation of these external markings is a matter of considerable un-
certainty ; nor does the position of the nephridiopores aid us in
determining the value of these surface-markings, as the author does
not state where these pores commence ; they are in line with the inner
(ventral) couples of cheetz in those segments where these are present ;
in the anterior twenty-six ‘‘ segments,’ however, they are on alternate
rings. The grooves separating the rings are stated to be well
marked, and in K. longus each ‘‘ segment” is biannulated.

Thus, from external characters, there is nothing to guide us to a
correct enumeration of the true somites.

Internally, the septa are,in most worms, of use, to some extent at
least, for the determination of somites, and the position of the sperm-
sacs and ovaries is so generally constant that these organs are
frequently of considerable help in confirming any otherwise doubtful
determination of somites.

But according to Michaelsen’s view of the anatomy of these two
worms, the first septum lies between “segments”’ 7 and 8; and the
ninth septum between “segments”? 23 and 24; so that two “ seg-
ments”? (instead of a single one as is usually the case) occur between
every two successive septa. Behind the ninth septum, however, the
condition of things usual in Oligocheta obtains. But although there
are two ‘“‘segments,” yet there is only one pair of nephridia.

Michaelsen gives no information as to the condition of the vascular
or nervous system, which might have aided us in solving the difficulty
as to the value of his “ segments.”

When J read his description of these worms I was reminded of
my own difficulty in determining the value of the external rings and
the limits of the somites in Wicrocheta rappi, and this difficulty
still further impressed itself on me when I examined the specimens
of the two new species of the genus described in the present paper ;
at first I reckoned as somites the markings which I have above

termed “ annuli.”
Now, when we consider the very abnormal condition of things

150 DR. W. B. BENHAM ON [Feb. 16,

presented by the position and arrangement of the internal organs,
which I have just mentioned, in Kynotus, and, still further, the posi-
tion of the few genital organs described by Michaelsen, I am inclined
to put a different interpretation on his ‘* serments,” and hence a
different enumeration of ‘ somites.”

In K. madagascariensis the only genital organs observed are the
spermathece ; these are in a condition similar to that of Microcheta ;
they are in rows of 22, 26, and 25 small sacs along the anterior
margins of the “segments”? 23, 24, and 25 respectively; the rows
extending nearly all round the body.

In K. longus there are four rows of eight spermathecee—one row
on each side of the anterior margin of the “segments” 25 and 26.
In this species he observed the sperm-sacs, of which there appears
to be a pair in front of each of the septa vi. and vii. [‘* Ein Paar
umfangreicher Sacke, vor den Dissepimenten vi. und vii., deutete
ich als Samensiicke ” ].

Now, if it be borne in mind that between the septa v. and vi. there
are, according to Michaelsen’s mode of reckoning, two ‘* segments,”
namely the 16th and 17th, and between the septa vi. and vii. like-
wise two “segments,” the 18th and 19th, we get the sperm-sacs
occupying a very abnormal condition indeed ; for in what Earthworm,
of all the many genera, do we find the sperm-sacs originating as far
backwards as the 16th “somite’’?* They usually occur in any somite
from the eighth to the twelfth, and where there are two pairs they
nearly always originate in somites x. and xi., or in somites xi. and xi.

I believe this apparently abnormally posterior position of the
genital organs and the other peculiarities of Kynotus can be ex-
plained by interpreting the external rings, not as ‘‘ segments” but as
annuli ; then between every two consecutive septa in the anterior
part of the body we shall have not two ‘‘segments”’ but two annuli,
that is one somite, and we shall find that matters work out more in
accordance with what we find in other Earthworms.

Granting that the gizzard lies in somite vi., which is a very usual
position for the organ in the family RAinodrilide (amongst which
Michaelsen places the worm), as well as in other families, the first
septum lies, not between “segments” 7 and 8, but behind somite vi.,
the second behind somite vii., and so on; this brings the sperm-sacs
into somites xi. and xii. (where they do occur in Mier. rappi, in
Rhinodrilus, Hormogaster, and perhaps in Brachydrilus), and the
spermathece are then in somites xv. and xvi. in K. longus, and in
somites Xiv., xv., and xvi. in K. madagascariensis ; and this position
agrees with that of the sacs in Mic. rappz.

Again, the nephridia will be one to each somite. Michaelsen
remarks on the variation in the position of the pores in the anterior
region of the worm, where they lie in some ‘‘ segments ” just behind
the septa, in others in the middle of the ‘‘ segments”; he sees only
one explanation of this, that the nephridia were originally one

The condition of the sacs in Geoscolex, Urocheta, and Diacheta is quite

different ; they may extend into these somites, but originate in a more normal
position.

1892.] NEW SPECIES OF EARTHWORMS. 151

pair to each “segment” and that has disappeared. It seems to me
that we can just as readily explain the apparent anomaly of the
nephridiopores being in the middle of the space between two septa
by a reference to other genera in which the areas of attachment of
septa have shifted from their original position, as I have mentioned
in M. belli. Rosa notes it in Hormogaster* and Beddard has re-
ferred to a similar partial shift of the septa in Libyodrilus °.

With regard to the papillee which exist on the 25th annulus (“seg-
ment’’ of Michaelsen) in K. madagascariensis and on the 26th in
K. longus, the suggested modification of enumeration brings each to
somite xvi. Michaelsen refers to them as carrying the apertures of
the sperm-ducts ; but as he saw no sperm-duct it is quite as probable
that they are independent copulatory structures, similar to those I
have described in the two species of Microcheta. The interpretation
which he gave to them, however, is quite natural, and I myself, till I
cut sections through them, presumed that they were the indications
of the spermducal pores, and we, as I have mentioned, know of no
other instance (except certain papillze in Pericheta, sp., whose struc-
ture is unknown) of such organs independent of the sperm-ducts.

According to my view, then, the genus Kynotus is not so aberrant
as Michaelsen believes. The genus is a near ally of Microcheta, if,
indeed, it be not identical with it, the link between it and M. rappi
(the “ type” of the genus) being provided by the new species described
in the present paper; and were it not for the very close agreement
between these species and the two earlier known species of Micro-
cheta (especially in regard to calciferous gland, “ hearts,’ doubling
of dorsal vessel, extent of clitellum, position of nephridiopore), I
should have referred them to Michaelsen’s genus.

1892.] ON THE GENUS PERICHETA. 1538

4. On some Species of the Genus Pericheta (sensu stricto).
By Frank E. Bepparp, M.A., Prosector to the Society.

{Received February 5, 1892.]
(Plates IX. & X.)

I have already communicated to this Society * some observations
upon the family Perichzetidee and upon the generic types which may
be recognized init. In the present paper I propose to describe some
species of Pericheta(s. s.). I regard those Perichetide as referable
to the genus Pericheta in the strict sense in which the sete are
disposed in a perfectly continuous circle round each segment, being
generally (? always) disposed along a distinct ridge in the middle of
the segment ; this gives to the species of the genus a very different
feel from either Megascolex or Perionyx, since the setze necessarily
project more and thus produce a roughening of the skin, very per-
ceptible when the worms are handled.

My experience of living Earthworms of the genus Megascolex is
limited to the examination of a specimen (as yet unidentified) from the
Seychelles. These worms are far more lethargic in demeanour than
the extremely active Perichete, and it is quite possible that this
difference may be general.

Another distinguishing character of the genus is the presence of a
pair of czca* projecting forwards from the intestine in the xxvith
segment. The gizzard, moreover, lies in segments viii.~x. and
the septa are wanting which should divide those segments. No true
Pericheta is known in which the spermatheca have more than a
single diverticulum apiece*. The clitellum never consists (with one
exception, P. fee) of more than three segments (xiv.-xvi.), and the
oviducal pore is generally, if not always, single and median +.

Most naturalists who have described species of Pericheta have
mentioned the number of setze on the segments ; but a segment has
generally been selected at random, and frequently no mention has
been made of the particular segment chosen. Prof. Bourne points
out that it is desirable to count the setee upon more than one seg-
ment, and he selects segments v., ix., & xxv.; he finds ‘‘ that the -

* “ Observations upon an American Species of Pericheta, and upon some other
Members of the Genus,” P. Z. S. 1890, p. 52.

> I refer later on in this paper (p. 165) to one exception to this rule.

* The second “diverticulum,” in the form of a pear-shaped pouch, which
occurs in Pericheta houlleti does not belong to the same category as the true
appendix of the spermatheca; this I have pointed out elsewhere [Q. J. Micr.
Sci. vol. xxx. p. 462].

+ Fletcher has described and figured an Earthworm (“Notes on Australian
Earthworms: Part II.”; Proc. Linn. Soc. N. S. W. ser. 2, vol. i. pl. 13. fig. 6
©, and p. 962), Pericheta queenslandica, which has the internal organization of
a true Pericheta, but “ interrupted” setze and paired oviducal pores; Pericheta
darnletensis, described on p. 966 of the same memoir, appears to be in every
respect a true Pericheta, but has also paired oviducal pores. This matter,
however, requires looking into again, as Mr. Fletcher suggests a slight doubt as
to whether the said apertures are really separate.

154 MR. F. E. BEDDARD ON WORMS [Feb. 16,

relation of these numbers to one another varies with other important
characters rather than the actual numbers themselves.”

Prof. A. G. Bourne’ considers that in all true Perichete there
are sete between the male pores. So far as my own experience
goes I agree with Prof. Bourne. The only possible exception that
occurs to me is Pericheta taprobane described in the present
paper (on p. 163), That species has setze between the male pores,
but differs from Pericheta ina few other points to which I direct
attention. Another point which appears to me to be of importance
is the size of the sete upon the anterior as contrasted with the
posterior segments ; in all the species of Pericheta described in the
present paper the sete of the eight anterior segments are very
much larger than those upon the segments which follow ; there is
an abrupt break at the end of segment viii.; up to this point the
setee get gradually larger upon successive segments. In Pericheta
taprobane, which may perhaps be a distinct genus, there is no such
marked difference between the segments in front of and those behind
the eighth. Although there is a sudden diminution in size of the
setze there is not always a corresponding increase in their numbers,
but there generally is an increase.

So much, then, for the generic distinctions of Pericheta.

As to the species there exists already some little confusion, and I
am not prepared to guarantee absolutely the novelty of the species
described in the present paper. When there were only a very few
species of the genus known, their discrimination was a much easier
matter than it is now; at the time that Perrier wrote his first
descriptions of Perichete it was a nearly sufficient definition to state
merely the number and position of the spermathece. There are
therefore a good many points, now known to be of systematic
importance, which are omitted or not clearly set forth in some of the
papers which record new species of Perichete. So far as we know
at present, the following are the principal external features which are
of systematic importance :—

(1) Whether the ventral setee are larger than the rest.

(2) The number of setze upon the segments.

(3) Whether the clitellum includes the whole of segments xiv.—

xvi.”

(4) Whether the sete are present or absent from some or all of
the clitellar segments; and if present whether they are
modified (as, for instance, in Pericheta houlleti).

(5) The number and arrangement of the anterior and posterior
genital papille.

(6) The position of the atrial pores upon the xvilith segment, 7. e.

whether they are more lateral or ventral.
7) Colour and size (including number of segments).

T should like to take this opportunity of calling attention to the
importance of illustrating these and other Earthworms by accurate

2 My attention was directed to the impor tance of this point by Prof. Bourne’s
paper upon Megascolex ceruleus (Q. J. Mier. Sci. vol. xxxii. p. 49).

1892.] OF THE GENUS PERICHATA. 155

coloured figures. The species of Pericheta generally (so far as my
experience goes, always) show characteristic differences of colour
which it is difficult to express in words so as to convey a sufficiently
accurate idea. The characters, moreover, which separate the species
of Pericheta are not always available ; some species are separable by
very well-marked characters, but others again hardly differ, except in
the number and position of the genital papille with which are
associated peculiar glands, and in their colour; immature specimens
often want the papille, and, in the absence of coloured figures for
reference, new species may be described which have no existence or
important facts in distribution may be ignored. At present there
are only two coloured figures of Perichetide extant on which any
reliance can be placed: these are Bourne’s figure of Megascolex
ceruleus and my own of Pericheta indica’. Several coloured
figures accompany Schmarda’s descriptions of Perichete in his
‘ Neue wirbellose Thiere,’ but these are not so useful as they would
be if the descriptions were sufficiently full to render identification of
the species possible *.

The chief internal characters which show variations are the
spermathecee and the atria. The number and position of the
spermathecze, and perhaps the relative size of the spermatheca and
its diverticulum, offer useful characters ; but they are rather difficult
to make use of, as the quantity of sperm in the diverticulum is
responsible for considerable variations in its form, as I point out in
the case of Pericheta sinensis (see p. 159). The atrium is sometimes
furnished at its point of opening with a dilated sac, the presence or
absence of which is very characteristic of a given species. The
extent of the glandular part of the atrium is perhaps often a valid
specific distinction, especially in such forms as Pericheta taprobane,
where it is extraordinarily small. The intestinal czeca are also
subject to some variation, which is, however, not common ; in two
species only are they absent, and in two others there are six pairs
instead of the normal one pair. There seems also to be some
variety in the position of the specially thickened intersegmental
septa; but this character is one which is best appreciated in large
species such as Pericheta forbesi, and is not always so clearly
marked in the smaller forms.

Whether the receptacula ovorum really vary from one to two pairs
is a matter which requires further investigation. At present I am
almost inclined to think that the existence of the two pairs of these
structures placed in segments xiii. and xiv. will prove to be charac-
teristic, not of particular species, but of the genus itself.

I have examined five or six specimens of this species, which has a
1 Vaillant’s figure of “ Megascolex diffringens” may be Pericheta indica.

2 Since the above was written I have received, through the great kindness of
Prof. Claus, these worms for identification.

156 MR. F. E. BEDDARD ON WORMS [Feb. 16,

very conspicuous coloration, illustrated in Plate IX. (fig. 4). The
specimens were all received alive from Kew Gardens; they were
brought to Kew in Wardian cases from Barbados and from Hong
Kong; it may be that the specimens from the two localities were
accidentally mixed, but the fact that each box contained another and
a distinct species in each case is against the supposition that there
had been an accidental transference of specimens from one box to
another. The occurrence of the same species of Pericheta in two
such widely-separated regions of the World is interesting, but it is not
the only instance seen in this genus; both Pericheta indica and
Pericheta houlleti have been recorded from the tropics of both the
New and the Old World.

The accompanying drawing (Plate IX. fig. 4) illustrates the colora-
tion of the species, which varies somewhat in individuals, preserving,
however, the same general plan. The body is markedly ringed as
in our own Allobophora fetida; there are alternate bandsof olive-brown
and pale brownish yellow ; in the individual figured the darker bands
are of a more distinctly green colour than in other specimens.

When treated with Perenyi’s solution the green, both of the
greener and browner individual, became very much brighter and
more distinctly green, and was finally dissolved out when the worms
were transferred to alcohol. This change of colour appears to be
due to the acid in the Perenyi’s fluid, as it was not produced by
alcohol alone.

This species is extremely strong and active and it is most difficult
to catch ; the buccal cavity is protruded when the animal is moving,
as in all other species of the genus that have been examined in the
living condition. The length is 70 mm. by 4 mm. in breadth’.

Number of segments 86.

The clitellum occupies the usual three segments, beginning and
ending sharply. There are no sete upon it.

The oviducal pore is single and median upon the xivth segment.

The atrial pores are not prominent; they are transversely elon-
gated slits upon the xvitith segment.

There are no genital papille.

The intestine commences in segment xiv. ; it has the usual pair of
ceca.

There are, as in most species of Pericheta, especially thick tufts
of nephridia on the septa in front of segment vii.

The ventral blood-vessel is not enclosed by the sperm-sacs.

The spermathece lie in segments vil. and viii. ; each has a diver-
ticulum bent upon itself three times.

The atrium has a large terminal sac.

I am not quite certain whether to identify this species with
Pericheta sumatrana or whether to regard it as new. The diver-
ticulum appears to be somewhat different in form, but this may
perhaps be accounted for by the distribution of the spermatozoa in
the pouch.

1 Another specimen measured 3 inches and consisted of 93 segments,

1892.] OF THE GENUS PERICHZATA. 15

PERICHATA DYERI, 0. Sp.

I obtained a single specimen of this Pericheta from Kew Gardens
in August of last year ; Mr. Crisp, one of the employés at the Royal
Gardens, brought me the worm, which had been remarked for some
days on account of its active habits ; it had obviously come from some
foreign country, but at that season so many plants in Wardian cases
arrive from abroad that I found it impossible to ascertain its exact
locality.

The colour of this species when alive (Plate IX. fig. 2) is a rich
brown, darker posteriorly ; the cuticle is markedly iridescent, the
iridescence being probably more strongly marked on account of the
dark background of pigment. During life it protruded, as other
Perichete do, the whole of the buccal cavity during its movements ;
the clitellar region was also continually contracted: in preserved
specimens this region of the body is, it should be observed, frequently
much narrower than the rest; the older term of cingulum is thus
particularly applicable, as the impression given is that of a belt
tightly drawn round the middle of the worm. When placed in weak
spirit, the worm threw out a quantity of turbid yellowish fluid.

After preservation the specimen measured 117 mm. and was com-
posed of 72 segments. ‘The circumference of the body in the region
of the spermathece is 13 mm.

The clitellum occupies the three usual segments, but does not
exactly coincide with the boundaries of those segments ; it commences
a little after the beginning of the xivth segment and terminates a
little before the end of the xvith. There are no sete upon the
clitellum. The seta formula is

Segment I. Wi XII. XXY.!
27 27 39 45

The oviducal pore is single and occupies the usual position.

The male pores lie upon the xviiith segment within the line of
sete, which are, however, interrupted for a short distance on either
side of each pore. On the same segment are two pairs of large
sucker-like papilla, which seem to have a concave surface. The
anterior pair (Plate LX. fig. 8) lie in front, and to the inside, of the
male pores ; the other pair occupy a corresponding position behind
the circle of setee of the segment, and touch the border-line between
the xviiith and xixth segments.

The spermathecal pores were not evident.

As to the internal anatomy. The alimentary tract is furnished
with a gizzard occupying the usual position and number of segments.
The paired ceca of the intestine arise between the xxvith and xxviith
segments and reach forward as far as the xxvth.

From segment xxviii. backward are paired series of “septal glands”’

‘ The segments selected for enumeration are not quite the same as those
chosen by Prof. Bourne (Q. J. Micr. Sci. vol. xxxii. p. 53, footnote); but I
find that the proportions and numbers are not altered by the segments which
I give.

158 MR. F. E. BEDDARD ON WORMS [Feb. 16,

such as I have described in other species of Pericheta’. They
appear, however (Plate X. fig. 1), to arise rather from the dorsal vessel
than from the septum; each gland is somewhat pear-shaped, with a
narrow stalk which approaches that of its fellow.

The sperm-sacs are in segments Xi., Xli.

The atria are very extensive ; the glandular part occupies segments
Xvi.—xxi. inclusive; the muscular duct opens directly on to the
exterior and is unprovided with a thin-walled sac.

The segments xvii., xviii., and xix. are masses of white glands
which are no doubt connected with the papillz already spoken of.

The ovaries (which are, as usual, attached to the front wall of
segment xiii.) are very large and bunchy.

The spermathece are present to the number ot four pairs, and lie
in segments Vi., Vil., viil., and ix. ; they open at the anterior boundary
of these segments and are very dorsal in position, the external
apertures being about 6 mm. from the nerve-cord. The pouch has
the usual shape; the diverticulum is half again as long as the
pouch.

The characters of the papille appear to distinguish this species
from all other Perichete with four pairs of spermathece. It comes
nearest to P. modiglianii.

The above description refers to a single specimen which I shall
keep as the type of the species. Since the description was written
I have received a large number of other examples, all living, from
Trinidad and Jamaica, and from Lagos on the W. African coast ;
the specimens from Trinidad I owe to the kindness of Mr. Hart,
Superintendent of the Botanical Gardens ; the other specimens came
from Kew. I kept a number of them alive for some weeks in the
hope that they might possibly produce cocoons ; unfortunately they
died without producing any. One of these specimens (which I
have also kept) is illustrated in the accompanying coloured drawing
(Plate IX. fig. 2). The examination of a large number of individuals
has shown that the characters of the genital papille as described
above are not quite distinctive of the species. In a good many
individuals the papillz were precisely as I have described them,
but in others there were only a single pair present, that pair lying
behind the male pores. These individuals therefore bear a very
clese resemblance to Pericheta sinensis. If one had only alcoholic
specimens to examine and were not allowed to dissect them, it
would indeed be impossible to distinguish the species by any at all
marked characters. The colour, however (cf. figs. 2 & 3, Plate IX.),
is here quite distinctive of the species.

PERICHZATA SINENSIS, 0. Sp.

Of this species of Pericheta | received a number of living speci-
mens from Kew Gardens; they came from Foochow in China. A
coloured drawing which I exhibit (Plate IX. fig. 3) was made by Mr.
Smit from the living worm. I ought to mention, however, that that

1 P. Z. 8. loc. cit.

1892.] OF THE GENUS PERICHZTA. 159

sketch does not show the prismatic colours, which were very evident.
The hinder part of the body is extremely transparent and of a pale
brown colour ; the blood-vessels and the paired septal glands were
quite clearly visible through the thin integument. The last dozen
segments or so are yellow-coloured; beyond the clitellum, which is
grey, is a patch of yellow due to the prostate.

The activity of this species is quite on a par with that of other
Perichzetes, and it possesses the same power of everting the buccal
cavity that I have referred to in the case of Pericheta indica’ and
the other species described in the present paper. M. Vaillant has
also figured the same protrusion of the buccal cavity in Pericheta
posthuma. In Pericheta sinensis the length of the fully everted
buccal cavity was quite equal to that of the first three segments of
the body.

The length of the species is 126 mm., the circumference at the
vilith segment 10 mm.

The individual with the above measurements had 104 segments.

The elitellwm, as is occasionally the case, does not coincide exactly
with the limits of the three segments (xiv.—xvi.) of which it is com-
posed ; it begins after the furrow separating segments xiii./xiv., and
ends before the intersegmental groove xvi./xvii. I could discover no
setz upon it.

The oviducal pore is single and median upon segment xiv.

The atrial pores lie upon segment xviii.

Genital papille.—There are two large sucker-like papille of
circular outline lying between segments xviii./xix. ; each is placed a
little to the inside of (and of course below) the atrial pore of its own
side.

The spermathecal orifices were not visible.

As to the interual anatomy, this species shows the usual characters
peculiar to the genus Pericheta.

There are a pair of ceca in the usual position.

There are four pairs of spermathece lying in segments Vi., vii.,
vil., and ix. In several individuals which [ dissected the proportions
between the pouch and its single diverticulum, as well as the shape
of the diverticulum, varied. The normal condition appears to be for
the diverticulum to be quite as long as the pouch ; like the pouch it
consists of a distal sac where the spermatozoa are retained and a
narrowed duct. The pouch itself contained no spermatozoa, only a
quantity of material presenting the appearance shown in the accom-
panying drawing (Plate X. fig. 3); it is of a fluid consistency
and contains minute granules as well as spherical bodies; the
drawing, I should say, represents the contents of the pouch of a
living worm. The diverticulum frequently shows a beaded appearance
represented in fig. 4; in one case the upper end of the diverticulum
was divided by constrictions into seven spherical chambers full of
sperm ; quite as often the diverticulum was tubular and of equal
calibre throughout, except of course the proximal end, which is always
narrower. My investigations upon the living worm, which I had

1 P. Z. 8. loc. cit.

160 MR. F. E. BEDDARD ON WORMS [Feb. 16,

hoped would be more thorough, were cut short by the drying up of
the specimens ; I had proposed to study the vascular system in detail,
but my failure to do so is the less to be regretted since Prof. A. G.
Bourne has recently published * an excellent account of the circu-
latory organs of the large Megascolex ceruleus, which would
probably in any case have rendered a similar account of the circula-
tory organs of Pericheta unnecessary.

I may, however, call attention to figs. 7 & 8, which represent a
portion of the capillary network upon the spermathecal diverticulum
drawn from the living organ. It will be noticed that this network
is of some vertical thickness ; its branches lie in two planes, both of
which are contained in the superficial layers of the pouch and do not
penetrate between the cells of its lining epithelium.

The atrium is not furnished with a terminal sac.

A crowd of closely pressed white egg-shaped glands corresponds
to each of the genital papille (Plate X. fig. 2).

The sete of segments Vi., vii., viii., ix. are longer and stouter than
those upon the anterior and posterior segments ; this is especially
the case with the more laterally placed.

The seta formula is as follows :—

Segment I. V. XII. XXyV.
28 26 42 48

PERICHETA BERMUDENSIS, 0. Sp.

I received thirty or forty examples of this Pericheta preserved in
spirit from the Bermudas; I am indebted for them to Surgeon-
Major Windle.

The specimens were all of about the same size; the length of one
specimen chosen at random is 120 mm., breadth 4 mm., number of
segments 93. The colcur (in alcohol) is a reddish brown dorsally,
passing into a yellowish colour ventrally.

The prostomium extends back over about half of the peristomial
segment.

The sete are small on the first setigerous segment ; they gradually
increase in size on the next three, and then get small again; they
are quite small on segment ix. They form complete circles.

The clitellum shows the unusual, though not unique (see de-
scription of Pericheta dyeri, yp. 157), character of not completely
occupying three segments. Instead of being developed over the
entire circumference of segments xiv.—xvi., it only commences to
be visible 1 mm. after the boundary-line of segments xiii./xiv.
and terminates at about the same distance in front of the boundary-
line between segments xvi./xvii. This gives the clitellum a
peculiar and very characteristic appearance. As it occurred in all
the specimens which I examined, I regard this reduction of the
clitellum as a valid specific character.

The clitellum is not entirely unprovided with sete; there is a

1 «On Megascolex ceruleus, Templeton, from Ceylon, &c.,” Q. J. Micr. Sci.
vol, xxxli. p. 49.

1892.] OF THE GENUS PERICHAETA. 161

single row present at the posterior boundary of the clitellar region,
which belong therefore to segment xvi. ; it is at this point that the
thick clitellar epithelium ceases. The sete do not forma continuous
ring round that segment (the xvith); they are visible only upon
the ventral surface and are developed for an equal distance on either
side of the ventral median line ; they extend for a distance of about
one quarter of the entire circumference of the segment. The
clitellar setze are quite obvious without having recourse to a micro-
scopical investigation of the integument, since the thick clitellar
epithelium is much broken along the line of their emergence. The
sete themselves do not appear to present any differences in shape
from those which are found in other parts of the body; they may
perhaps be a trifle smaller, but there is no such differentiation as
occurs, for example, in Pericheta houlleti. The most careful search
failed to show any sete on either of the two remaining segments of
the clitellum : in one specimen I counted 20 setze on segment xvi.;
in another there seemed to be rather fewer, but there was no per-
ceptible variation in the length of the line occupied by the sete in
different individuals.

I have been particular in calling attention to the characteristics of
the clitellum, not only because the points to which I have directed
attention are of specific importance, but also for the special reason
that they serve to discriminate Pericheta bermudensis from Pericheta
aspergillum. I was at first inclined to regard the species de-
scribed in this paper under the name of Pericheta bermudensis as
being identical with Pericheta aspergillum. The latter was first
described by Perrier * as being “sans désignation d’origine.’ As I
received a few years ago some Earthworms collected by Mr. Shipley
in the Bermudas which seemed to be P. aspergillum, I considered
that the present species was the same, as the individuals agreed, ona
superficial inspection, with Pericheta aspergillum. However, in
Perrier’s description of P. aspergillum there are characters mentioned
which appear to show that I am right in regarding Pericheta ber-
mudensis as a distinct though closely allied form; in the figure”
illustrating Pericheta aspergillum sete are figured upon all the
segments of the clitellum ; but in the text the matter is left a little
obscure. M. Perrier says (p. 120), “Je n’ai vu sur la ceinture que de
faibles traces. . . . des ceintures de soies.”

The great difference in size may possibly also be a valid specific
difference ; no doubt this character is one which has to be used with
special caution in the case of Earthworms. ‘There are other points,
too, which I shall call attention to in referring to the characters
offered by the male generative pores and the spermathecal pores.

The dorsal pores commence, as in Pericheta aspergillum, between
segments x./Xxi.

The ovidueal pore lies upon the middle ventral line of segment xiv.

162 MR. F. E, BEDDARD ON WORMS [Feb. 16,

The male pores are upon segment xviii., comparatively near to
the ventral median line ; they are not, as is, for example, the case
with Pericheta affinis, at the sides of their segment. ‘The sete of
segment xviii. are present between the two pores, but they cease to be
visible some little way from the pores on each side. ‘The pores them-
selves lie in the direct line of the circle of setee. Close to each of the
apertures of the atria is a group of rounded orifices, which in one
specimen showed the following arrangement :—There were four on
one side and five upon the other, each group of pores lying in a circle
below, and to the inside of, the atrial pores. The arrangement there-
fore, as well as the number of these pores, shows some differences from
Pericheta aspergillum ; 1 occasionally observed fewer than four pores,
but never anything like so many as eleven, which Perrier states to be
the number found in Pericheta aspergillum. When the cuticle is
stripped off, these pores become very obvious and can be easily counted
with a lens. Examined under the microscope they do not present
the appearance of pores, but of solid papillze covered by a reticulation ;
they are in fact, as I have already pointed out * for Pertcheta asper-
gillum and other species of the genus, the openings of masses of
unicellular glands.

I could not see the spermathecal pores, and there was no develop-
ment of accessory papillz corresponding to those which have just
been described as occurring near the atrial pores. This is another
point in which Pericheta bermudensis differs from Pericheta asper-
gillum, where such papillle have been described and figured by
Perrier.

The gizzard occupies segments viii.—x., the septa of those segments
being absent ; the remains of the septa are to be recognized in a series
of ligamentous bands which attach the gizzard to the parietes; of
these there are three pairs: two on each side are attached, close to
each other, not to the gizzard itself, but to the septum which lies
just in front of it; they pass obliquely backwards and outwards ;
behind these and nearly at the posterior extremity of the gizzard is
another band on each side. ‘The walls of the esophagus behind the
gizzard are much folded (internally) and very vascular in segments
Xii.—xiv., particularly in segment xii. ; this region no doubt represents
the calciferous glands of other Karthworms, which do not here form
distinct diverticula.

In segments v. and vi. are “‘ lood-glands”’ which present aracemose
appearance.

The intestine is provided with the usual pair of ceca.

The sperm-sacs are in segments xi. and xil.

The curved duct of the atrium opens directly on to the exterior,
and not through a dilated terminal portion; it is surrounded by
innumerable small white glands, which correspond to the pores
which surround the external orifice of the atrium.

The ovaries are in segment xiii.

There are two pairs of receptacula ovorum in segments xiii.‘ and
xiv. respectively. Those of segment xiii. lie above the ovaries.

The three pairs of spermathece lie in segments vi., vii., and viii.
The oval pouch of the spermatheca has a long narrow duct: the
diverticulum has the same form but is much smaller ; it is hardly as
long as the duct of the main pouch.

PERICHATA TAPROBANA, 0. sp.

The following description is based upon the examination of some
half-dozen examples of a Pericheta from Ceylon. The specimens
were collected a good many years ago by Prof. Moseley and were
deposited by him in the Oxford University Museum. Mr. W.
Hatchett Jackson was so good as to place them in my hands for
identification and description. The worms were labelled “ Pericheta
cingulata,”’ and I presume therefore that they agreed with
Schmarda’s coloured figure of that species”. As, however, Schmarda’s
description of the species is not by any means sufficient for
identification, 1 do not think it safe, in the present state of our
knowledge of this genus of Earthworms, to define any species by
colour only.

M. Vaillant *, to whom we are indebted for the first anatomical
account of Pericheta, identified six Earthworms in the Paris Museum
with P. cingulata, apparently basing this identification upon the
shape of the sete. The futility of such a character is shown by the
fact that Perrier’ was rightly able to distinguish several distinct
species among the individuals which were all called ‘ Pericheta
cingulata” by Vaillant. The name ‘‘ cingulata”’ was applied by
Schmarda in the belief that the species was characterized by pos-
sessing a clitellum. It is not, however, on this ground that I think
it desirable to drop the name Pericheta cingulata altogether.
Vaillant’s Pericheta cingulata according to Perrier’ is practically
indistinguishable from the Pericheta posthuma of the same author ;
and it is impossible to be certain that they are different from Perrier’s
Pericheta affinis—so at least Prof. Perrier thinks, and Dr. Horst °
agrees with him. But I do not follow Perrier in retaining the name
Pericheta cingulata for Pericheta posthuma, since there are really

1 Pletcher (“ Notes on Australian Earthworms, Part III.,” Proc. Linn. Soc.
N. 8. W. ser. 2, vol. ii. p. 394) describes in Pericheta canaliculata ‘a pair of
smooth white sacs” lying above the ovaries in segment xiii., which are doubtless the
same structures. Zo pairs of these bodies occur in several species of Pericheta.

should be remarked, however, that Vaillant neither figures nor describes sete
upon the clitellum; he remarks, indeed, “la ceinture seule en [des soies] est
privée.” They are present in Pericheta affinis, so that probably Dr. Horst’s
earlier (Midden-Sumatra, Vermes, p. 4) identification of P. eingulata (of
Vaillant) with Pericheta indica was more correct.

164 MR. F. E. BEDDARD ON WORMS [Feb. 16,

no reasons either for believing or disbelieving that Vaillant’s Peri-
cheta cingulata is the same species as Schmarda’s Pericheta
cingulata.

In the specimens which I examined there is no trace of the
natural colour left; the worms are a pale brownish grey—the
clitellum a darker brown. As they do not agree with any Pericheta
of which there is an adequate description, I give them the new name
Pericheta taprobane.

There are only four species of Pericheta which agree with the
present in possessing only a single pair of spermathecee, so that it is
more easily to be discriminated than species which possess the more
typical number of three or four pairs. The species in question are
Pericheta sangirensis, Mich.', Pericheta ceylonica, F. E. B.’,
Pericheta quadragenaria, E. P., and Pericheta elongata, E. P.
Pericheta taprobane differs from the last two species in a number of
points ; it will be sufficient here to mention one point of difference only
for each species. Pericheta taprobane differs from Pericheta quadra-
genaria in the size and form of the spermathecal appendix ; from
Pericheta elongata in the characters of the ‘‘ prostate” ; from Peri-
cheta sangirensis in the absence of a dilated sac at the distal
extremity of the atrium. Pericheta ceylonica is distinguished by
having two pairs of atria.

Pericheta taprobane is a stout worm, measuring about 80-
100 mm. ; the largest specimen was 105 mm. in length; an in-
dividual measuring 84 millims. in length had a breadth of 6°5 mm.
and was composed of about 114 segments.

The worm undoubtedly belongs to the restricted genus Pericheta,
although, as will be seen presently, one of the distinctive characters
of the genus is absent: the sefe form continuous rows and are
numerous ; on the first setigerous segment of one specimen I counted
52 setee, on the fifth 81, on the twelfth segment of the same indi-
vidual there were 74, on the twenty-fifth 67. The seta formula
is therefore as follows :—

Segment I. y XIL. XXyV.
52 81 74 67

The setz are present on a// the clitellar segments and form complete
circles. Their form is not different from that of the setze elsewhere.
Those upon the hinder segment of the body are nearly twice as long
as those upon the anterior.

The clitellum is composed of the usual three segments, but is a
little indistinct at both ends.

The oviducal pore is single and median; it lies in front of the
circle of sete of segment xiv.

The atrial pores are upon the xviiith segment and are sometimes
very prominent—forming conical elevations—owing to a protrusion

1892.] OF THE GENUS PERICHATA. 165

of a part of the atrium ; the setz are interrupted for a short space
on either side of each pore, which, however, lie directly in the line
of the setze. I counted seventeen sete between the male pores.

I could find zo genital or copulatory papille of any kind.

The spermathecal pores were very evident in all the specimens;
they lie between segments vii./viii.

The dorsal pores commence between segments xii./xiii.

The anterior segments of the body are bi- or tri-annulate.

With regard to the internal anatomy of the species, I only
direct attention to those points which are known to be of importance
in the discrimination of species. The position of the gizzard is
perfectly normal ; it lies in segments viii.—x., and the septa between
these segments have nearly entirely disappeared, being represented
only by a few ligaments binding the gizzard to the parietes. The
intestine is very remarkable on account of the fact that there are no
ceca. I looked for these structures very carefully, and entirely
failed to discover them; they are always (according to my ex-
perience) quite easy to find when present. I must therefore
conclude that the present species is unique in the absence of ceca.
Although there appears to be no Earthworm known on other grounds
referable to the genus Pericheta (s. s.) which possesses no intestinal
ezca, Mr. Fletcher* has described a Megascoler in which ceca are
present. In Pericheta queenslandica, a worm with “ interrupted
circles of sete,” there are a pair of lateral ceca arising from the
intestine in segment xxv. and directed anteriorly, as in all true
Perichete with the exception of Pericheta taprobane*; these two
species evidently render it impossible to define strictly the genera
Pericheta and Megascoler, though as a matter of convenience those
names may he, for the present at least, retained until more exceptions
are made known. In other particulars the alimentary tract of this
Earthworm does not diverge from the normal.

The intersegmental septa commence to be distinct after the fourth
segment ; the first four septa, viz. those bounding segments v.—vii., are
rather thickened ; as are also the first two septa which lie behind the
gizzard, that is to say those which separate segments x./xi. and xi./xii.
The thick septa in front of the gizzard are covered with very con-
spicuous nephridial tufts.

The sperm-sacs lie in segments x., xi., and xii.

The afria consist as usual of a thick muscular duct bent upon
itself and of a glandular portion consisting of ramifying ceca; the
latter is fairly compact except where it is cleft at its junction with
the non-glandular part. The glandular part is much smaller than
is usual in this genus, and is entirely limited to the xviiith segment.
The muscular duct is unprovided with a dilated sac at its extremity.

There is only a single pair of spermathece, which lie in segment viil.
They also are small; and, as the facts contained in this account are
based upon the dissection of several examples, I may emphasize the

* Tam not certain as to Pericheta ceylonica.

166 MR. F. FE. BEDDARD ON WORMS [Feb. 16,

smallness of the atria and the spermathece as a characteristic of the
species. Each spermatheca consists of a globular portion communi-
cating with the exterior by a narrow duct, to which is appended a
small diverticulum consisting also of a swollen terminal portion and
of a narrow duct.

PERICHETA MORRISI, 0. sp.

I name this species, of which I obtained several living examples
from Kew, after Mr. Morris, Assistant Director of the Royal Gardens.
Three or four specimens were forwarded to me, of which only one
was sexually mature; the following description is based upon that
specimen.

The species comes from Penang.

The accompanying coloured sketch by Mr. Smit (Plate IX. fig. 1)
represents the natural colours of the worm and shows its distinctness
from Pericheta sinensis, with which species, however, it cannot be
confounded, as will be seen in the course of the following description.

The worms during life protruded the buccal cavity, as apparently
all species of Pericheta do.

The length of the specimen (after preservation in weak, followed
strong, alcohol) is 52 mm.; the number of segments in the body
is 93.

The sete, as in other species, form continuous rows.

The clitellum begins abruptly with the commencement of segment
xiv., but does not terminate exactly at the posterior boundary of
segment xvi.; the glandular substance ends at the level of the setz
which are present on the last segment of the clitellum, as in Peri-
cheta bermudensis (see p. 160); the setze of this segment, as in the
species with which I have compared Pericheta morrisi in this
particular, are only present upon the ventral surface.

The oviducal pore occupies the usual position.

The atrial pores open on to the xviiith segment, and are not
separated by a very wide interval; they are in the line of sete, but
the setze cease for a short space on either side of each pore.

The spermathecal pores lie between segments y./vi. and vi./vii.

There are no papille in the neighbourhood of the male pores,
although on a subsequent dissection of the worm I noticed some
minute white glands in the xvilith segment. Papille, however, are
present upon certain of the anterior Bi in the neighbourhood
of the spermathecal apertures.

Upon each of segments vii. and viii. is a single circular disk occu-
pying the median ventral line of the segment and lying just in front
of the circle of setee belonging to the segment.

The gizzard lies in segments viii.—x., the mesenteries which should
divide those segments being absent.

The usual pair of ceca are present.

The esophagus in segments x.-xiv. is much thickened and of
a whitish appearance. This region doubtless corresponds to the
calciterous glands of other Earthworms, which do not appear to be
developed as distinct pouches in the genus Pericheta.

1892.] OF THE GENUS PERICHATA. 167

The atrium is not furnished with a distal sac.

There are two pairs of spermathece, which lie in segments vi. and
vii.; the appendix is a tube of uniform calibre and is very nearly as
long as the pouch. In the case of one spermatheca, the appendix
is twisted at its commencement round the stalk of the spermatheca.

PERICHETA BARBADENSIS, Ni. Sp.

In June of the present year I received from Kew Gardens five
living worms of the genus Pericheta, which were all of a reddish-
brown colour with a grey clitellum ; the iridescence of the cuticle
was very marked, on account of the dark pigment in the body-wall ;
when the worms were killed in weak alcohol, a quantity of yellowish
fluid was expelled from the dorsal pores.

In spite of the close similarity in colour between all five specimens,
I believe that they are to be referred to two distinct species, of which
one—that which I call Pericheta barbadensis—is somewhat protean,
showing considerable variations, which I do not, however, regard,
for reasons which will be stated presently, as being of specific value.
I describe the second species subsequently (see p. 169).

Two of the specimens were of about the same size, measuring
4 inches in length (when preserved in strong alcohol, after having
been killed in weak alcohol); the diameter in front of the clitellum
is 4 mm. The length of the preclitellar somites is 18 mm.;
the clitellum itself measures 4 mm. The number of segments
is 78.

In this individual—which I call a—setze were present upon the
last segment of the clitellum (Plate IX. fig. 6); the clitellum itself in
all three specimens is fully developed upon all the segments xiv.—xvi.
and bears anteriorly the single median oviducal pore; the number
of sete upon the last segment of the clitellum is small, about half
a dozen.

In the second individual (4) the number of sete upon the last
segment of the clitellum is greater than in a.

In the third individual (c) the number of setee upon the last seg-
ment of the clitellum is about as great as in 4, but in addition the first
segment of the clitellum (7. e. no. xiv.) bears three, or possibly four,
setze on each side of the oviducal pore (Plate IX. fig. 7), which there
lies within the circle of sete of its segment, and not, as is usually
the case in the genus Pericheta, in front of the setee. It might be
supposed that these three individuals represented merely three stages
in the disappearance of the setee belonging to the clitellar segments.
In immature worms sete are always present upon the clitellar seg-
ments. Iam not aware that any exact observations have been made
as to the time and manner of their disappearance in those species
which have, when adult, a clitellum devoid of sete. But in the
present species the differences in the clitellar setze coincide with
differences in the genital papille and also with differences in the
number of spermathecee. But, as will be seen presently, it does not
happen that the worm with the fewest setze upon the clitellum has
the most marked development of the genital papille. Hence I

168 MR. F. E. BEDDARD ON WORMS [Feb. 16,

should conclude that this species is one whose characters are not
yet definitely fixed ; it is evidently on the way to entirely losing the
setze upon the clitelluw.

The genital papille, as has been already remarked, differ in the
three individuals.

In a there is, in the first place, a median sucker-like papilla upon
segment vii., just in front of the circle of setee; and in the second
place, a single median papilla occupying an exactly corresponding
position upon segment xviii.

In 4 there is no anterior papilla or papille ; on segment xviii. are
two papillz placed on the inner side of each atrial pore and lying
below the circle of sete; the innermost papilla on each side is below
as well as to the inside of the outermost, which occupies a corre-
sponding position with regard to the male pore.

In ¢ the arrangement is by far the most complicated, and yet
this individual is the one which has the most sete upon the clitellum.

There are no anterior papill ; on the eighteenth segment a small
circular papilla lies above each atrial pore and another lies exactly
below it, on the boundary-line between segments xviii./xix. In the
middle of segment xviil. are two papillz lying side by side and above
the sete of that segment. On the right-hand side of the body is
another papilla, which lies just above one of these two. There are
thus seven papillz in all.

In all three individuals the atrial pores are lateral in position,
being separated by the entire diameter of the body, which is here a
trifle wider than either anteriorly or posteriorly.

With regard to the internal anatomy, all three specimens showed
the following characters in common :—

The gizzard occupies the usual position, and there are a pair of
intestinal ceca.

The intestine has a small typhlosole.

The aéria have an extensively developed glandular portion, which
extends from segments xvil.—xxi. in 6 and from xviii—xxii. in a; itis
rather smaller in ec, but then the worm itself is smaller *.

I found two pairs of egg-sacs attached to the posterior face of the
septa dividing segments xii./xiil. and xiii./xiv. ; they are pear-shaped
with a long stalk, and not very wide at the widest end.

The position and number of the spermathece differ in the three
individuals: in @ there were two pairs somewhat unsymmetrically
disposed ; they open, however, in the intersegmental grooves v-/vi.
and vi./vii. In segment vi. lie a pair, of which one was very small
and immature; the fully developed spermatheca consists of an oval
pouch terminating in a narrow duct, from which arises a long
cylindrical appendix. In segment vii. the spermatheca of the right
side of the body had the same characters ; on the left side the duct
of the spermatheca, although opening in the normal position, is
greatly elongated, traversing septum vii./viili. and expanding in the
vilith segment into the large oval pouch. The diverticulum of this
spermatheca lies in segment vi.

It measures 84 mm. and consists of 64 segments.

1892. ] OF THE GENUS PERICH ETA. 169

In 4 there are three pairs of spermathecze in segments vi., vii., and
viii., which are in every respect perfectly normal.

In ¢ there are two pairs lying in vi. and vil., but quite normal in
structure.

It may be that Iam wrong in associating all these individuals
together under one specific name.

PERICHZTA HESPERIDUM, 0D. Sp.

Two individuals out of the five specimens just referred to, of which
I have described three under the name,of Pericheta barbadensis,
presented certain differences; these differences would, if the speci-
mens had come from a different locality, be undoubtedly considered
of specific value. As it is, I am uncertain, considering their ex-
ceedingly close similarity in coloration, whether to regard all five
individuals as belonging to one protean species, or whether to regard
the two specimens described here as a distinct species. Since the
differences which they show to the three described as Pericheta
barbadensis are more marked than either of the three exhibit among
themselves, I give them at least a provisional name.

The external characters are those of Pericheta barbadensis, ex-
cepting that there are no sete upon the clitellum and that there are no
genital papille. In describing the last species, I pointed out that
there is a gradual reduction in the three specimens of the sete upon
the clitellum, which is accompanied by a reduction in the genital
papillae. In the two specimens which I describe here as Pericheta
hesperidum this reduction in number has culminated in the total
disappearance of both the clitellar setae and the genital papille.
Tf it were not for certain differences in the internal anatomy, to which
T shall call attention later, these facts would rather show that there
is no necessity for separating the forms specifically.

In the internal anatomy there are, however, differences. I should
say, however, that I have only dissected one of the two individuals
associated together here under the name of Pericheta hesperidum.

In that worm the ceca are remarkably small as compared with
those of other species. The intestine is provided with a fairly
well-marked typhlosole ; it commences in the xvth segment.

There are two pairs of spermathece, which lie in segments vii.
and viii. and open on the border-line between segments vil./vili. and
viii./ix. ; in the case of the anterior pair, the displacement of mesentery
makes the apertures, when viewed from the inside of the body, look
as if they were placed in the middle of segment vii.

The diverticulum is contorted.

I only found a single pair of receptacula ovorum in place of the
two pairs of the last species; they are attached to the front wall of
segment xiii. and lie above the ovaries; they are elongate and lie
obliquely on the septum.

The atrium shows a difference of importance from the last species ;
this is the presence of a terminal sac. This sac is, however, so
extremely small in the present species that it needs careful looking

Proc. Zoou. Soc.— 1892, No. XII. 12

170 MR. F. E. BEDDARD ON WORMS [ Feb. 16,

for and might very easily escape attention; the muscular duct of the
atrium becomes very narrow just before it opens into this sac.

PERICHATA MAURITIANA, 0. Sp.

In August of last year I received from Kew a number of living
Earthworms which had been accidentally imported from Mauritius;
they proved on examination to belong to two distinct species: one
is a Urochata, indistinguishable, so far as I can see, from Urocheta
corethrura ; the other is a Pericheta belonging appateutly to a new
species.

At present one species of Pericheta is known to occur in Mauritius;
and a second, although described {rom Australia, is believed to be
indigenous to Mauritius. The first is Pericheta mauritii of Kinberg,
which cannot be satisfactorily identified ; the second—Pericheta
peregrina—has been lately described by Mr. Fletcher’, and so can-
not be confounded with Pericheta mauritiana, which comes much
nearer to Pericheta rubusta from the neighbouring Ile de France.

The colour of the living worms was reddish brown, with a pale
greyish-brown clitellum, Their habits are those of other species of
Pericheta.

The length of the largest specimen, after preservation with corrosive
sublimate and alcohcl, is 80 nm.

The number of segments is 85.

The clitellum occupies the usual segments ; the last segment of
which it is composed has a short row of sete in the middle ventral
line, as in Pericheta bermudensis.

The oviducal pore is single and median upon segment xiv.

The atrial pores are in the line of sete of segment xviii. ; the sete
are interrupted for a short distance on each side of both apertures.

The genital papille are restricted to the neighbourhcod of the
atrial pores. There are three on each side, lying below and to the
inside of the atrial pores.

The gizzard lies in segments viii. and ix.; it apparently does not
extend, as this organ so often does in other species of Pericheta,
into segment x.

The usual pair of ceca are present, which originate from the
intestine in segment xxvi. and extend forwards to the anterior
boundary of segment xxv.

There are two pairs of spermathece in segments vil. and viii. The
diverticulum is as long as, cr perhaps rather longer thar, the sperma-
theca itself. It consists of a slightly sinuous tube with a globular
extremity.

There are two pairs of receptacula ovorum (Plate X. fig. 5), both
of which have the form which seems to be so generally met with in
this genus of Earthworms.. The organ is oval, with a long tail
directed towards the median ventral line. The receptacula ovorum
are attached to the front wall of segments xiii. and xiv. The anterior
pair lie above the ovaries.

1892. ] OF THE GENUS PERICHATA. 171

The atrium is not provided with a terminal sac ; the glandular
part of each atrium is very extensive, and reaches from segment xvii.
to segment xxii.

Between the opening of the atrium and the nerve-cord on each
side of the body are three small white oval glands (p.g., fig. 6,
Plate X.), which correspond to the papillze visible ou the exterior of
the xvilith segment.

Note on a Perichzeta from Singapore.

I received a single specimen of this Pericheta in a living condition
from Kew Gardens; it had reached there in a Wardian case from
Singapore.

Unfortunately I omitted to make any notes upon the worm
while alive; a quantity of other material which came about the
same time obliged me to preserve it at once for future study; the
specimen was killed in Perenyi’s solution and investigated by
means of transverse sections. It is very possibly the same species
as that which I have called Pericheta morrisi, and described in the
present paper; but my notes upon its diagnostic characters are so
tar from being complete, that I do not venture to express an opinion
as to the name which should be applied to it.

It measured 23 inches when preserved.

The clitellum occupied the usual three segments, but I am not
certain as to whether setze were, or were not, present.

On the xviiith segment was a single median papilla placed between
the two atrial pores.

I observed the gizzard to occupy the usual position and that
ceca were present. There are two pairs of spermathece in segments
v1. and vii. ; these agree very closely with those of Pericheta morrisi
in the proportions of the appendix to the spermatheca, but the
extremity cf the former was swollen, forming an oval sac.
This is possibly merely due to the presence of more sperm in one
case than in the other.

I desire to call special attention to the structure of the atria.

These organs have the usual form characteristic of the genus
Pericheta.

Their minute structure, however, presents one character of some
little interest, which has not yet been recorded in the genus.
Transverse sections through the stout muscular duct by which the
secretions of the glandular part of the atrium reach the exterior
show that the muscular sheath encloses three separate ducts instead
of only one, as is the case in all other species which have been as yet
investigated micrescopically. One of these tubes is large and is the
main conduit of the secretion of the gland ; the two other tubes are
equal in size to each other, but very much smaller than the main
tube.

The smaller tubes retain their distinctness from the larger
tube until near the external orifice, though still remaining enclosed
within the same muscular sheath. Just before the external aperture

172 ON WORMS OF THE GENUS PERICH ATA. [Feb. 16,

they fuse with the larger tube, and all these open by a common
orifice.

Traced in the reverse direction, one of the two smaller tubes was
found to communicate with a separate lobe of the branched atrium.
Whether this was or was not the case with the second of the two
smaller tubes, I am not able to say.

These facts are of interest in relation to the structure of the
terminal portion of the male efferent apparatus in Pericheta
ceylonensis, a species which I described some years ago.

Pericheta ceylonensis differs from all other species of the genus
in possessing ¢wo glandular bodies on each side in the xviiith seg-
ment. One of these is a lobed atrium like that of Pericheta in
general, but with a straight instead of a curved muscular duct; the
other is a tubular gland like the atria of Acanthodrilus. Unfortu-
nately I have not been able to ascertain with which of these two
glandular appendages the vasa deferentia communicate.

It seems to me that in this Pericheta there is a commencing
separation of each atrium into two halves which culminates in
Pericheta ceylonensis.

1892.] ON HALIAETUS PELAGICUS AND H. BRANICKII. 173

5. On Specimens of Haliaetus pelagicus and H. branickii now
living in the Zoological Gardens of Hamburg. By
Heinricu Borav, Ph. D., Director of the Hamburg
Gardens, C.M.Z.S.

[Received February 6, 1892.]

On Dec. 12th, 1882, we received as a present from Capt. Haveker
a very fine specimen of Haliaetus pelagicus, the Giant Sea-Kagle,
which he had brought from the Amur River in Eastern Asia. This
bird is still in our possession, and is, I believe, the first of the species
that has ever been received alive in Europe. On Feb. 6th, 1887, a
second specimen of a giant Haliaetus from Eastern Asia was presented
by Capt. B. Dethlefsen, who had brought it from Corea. This bird
was so much like the first one—except especially in the want of the
white patch on the shoulders—that I long thought it a young of
Haliaetus pelagicus. 1 expected it would get the white shoulder-
patches after some time and turn out to be a true H. pelagicus; but
year after year elapsed and no change took place.

Last summer, when Dr. R. Bowdler Sharpe visited our Gardens, I
told him about our birds and communicated to that excellent
ornithologist my observatious about our Corean bird. A short time
after, Dr. P. L. Sclater asked me about our two Haliaeti and
directed my attention to the new species Haliaetus branickii of
Taczanowski, described in his “ Liste supplémentaire des Oiseaux
recueillis en Corée par M. Jean Kalinowski” (P. Z.S. 1888, p. 451).

I compared my bird with the description given by Taczanowski,
and was at once convinced that our Corean bird belongs to the new
species.

I now send for exhibition exact figures of our two birds, carefully
taken from life, and the following short descriptions of them.

The Corean Sea-Eagle (Haliaetus branickhii) is of a deep dull slaty-
black colour, which inclines to brown only in certain reflexions of
light ; the streaks of the feather-shafts on the neck are somewhat
lighter. The upper and under tail-coverts, the shoulders, and the
thighs are black, and only the tail is white. The bill is not very
different from that of Haliaetus pelagicus except in colour. The
bill and feet of H. ranickii are less yellow than those of the other
species.

The Giant Sea-Eagle (H. pelagicus) is decidedly brown-black ;
besides it is at once to be distinguished from HY. branickii by its
shoulder-patches, thighs, and upper and under tail-coverts being
white, so much so that the whole hinder part of our beautiful bird
is of a white colour.

The iris of H. pelagicus is pale yellow, that of H. branickit of the
same colour, but many delicate streaks make it somewhat darker.
In both species the margin of the upper eyelid is bare and yellow
like the bill; but in H. dranichii the bald streak is more distinct
than that of H. pelagicus.

174 ON THE EXPEDITION UP THE RIO PILCOMAYO. [ Mar. l,

In the plumage of the lores our birds are not quite so different
as would appear from Taczanowski’s description above referred
to; probably these differences vary according to age or sex. Both
our birds have the lores delicately feathered, but the bristle-feathers
of H. branickii are lighter than those of H. pelagicus.

H. pelagicus and H. branickii are the largest of all the Eagles.
Both our birds live, together with many other Eagles and birds of
prey, in a large cage of our Hagle-house. When at rest they are
generally to be seen sitting close together; their cry is in corre-
spondence with their giant size, much louder and more penetrating
than that of all the other Eagles.

March 1, 1892.
Dr. A. Giinther, F.R.S., Vice-President, in the Chair.

The Secretary read the following report on the additions to the
Society’s Menagerie during the month of February 1892 :—

The total number of registered additions to the Society’s Mena-
gerie during the month of February was 84, of which 37 were
by presentation, 7 by birth, 30 by purchase, 4 were received in
exchange, and 6 on deposit. The total number of departures during
the same period, by death and removals, was 75.

Amongst these special attention is called to the following :—

1. Two Short-winged Tyrants (Machetornis rixosa), purchased
Feb. 15. These are the first examples of this bird that have
reached us.

2. A female Beatrix Antelope (Ory beatriz) from Arabia,
presented by Lt.-Col. Talbot, Feb. 18. The pair of this Antelope
presented by Col. Ross in 1890 being still alive, the receipt of
another female makes a very acceptable addition to our series.

Mr. J. Graham Kerr gave a short account of the late Captain
John Page’s expedition up the Rio Pileomayo, which he had
accompanied as Naturalist upon the recommendation of the Council
of this Society. Leaving England in the summer of 1889, Mr. Kerr
spent some months studying the Zoology of the Pampas. In
January of 1890 he left Buenos Aires in the steamship ‘ Bolivia,’
which had been specially constructed for the expedition, and after
several weeks spent on the Parana, and a short preliminary trip u
the Bermejo River, entered the Pilcomayo in March of 1890. Rapid
progress was made for the first few days—the river being, although
intensely tortuous, comparatively broad and unobstructed. The
banks were here covered with thick and almost impenetrable forests,
chiefly of small scrubby trees, and characterized by a great paucity
of animal life. The most conspicuous mammals were :—the Carayd
Monkey (Mycetes caraya), troops of which were to be seen in the
trees by the river-side ; the Mirikina (Nyctipithecus trivirgatus), of
which some half a dozen specimens were killed ; the Tapir (Z'apirus
americanus), the tracks of which were to be seen in all directions ;

two species of Deer—Cariacus paludosus, frequenting the open
inarshy spots, and Cariacus simplicicornis, inhabiting the woods; and
two Peccaries (Dicotyles torquatus and D. labiatus). Of Carnivora,
the Jaguar was the most frequently seen; the Puma being equally
abundant but less conspicuous, owing to its inhabiting the open
campo. In the waters of the river near the mouth an Otter
(Lutra paranensis) was abundant.

As the expedition proceeded farther up the Pilecomayo, the
channel became narrower, and a great fall in the level of the water
taking place, progress became much obstructed. Still, however, the
‘ Bolivia’ struggled to get onward, but eventually came to a full
stop about 300 miles from the mouth of the river, in the midst of a
parched and salt-saturated country, consisting almost entirely of
open campo, in which animal and vegetable life of all kinds was
marked by extreme poverty and lack of variety. The greater part of
the men here deserted, the leader and the doctor both died; and the
remainder, numbering nine in all, after a detention of over four
months, were ultimately rescued by a military search-party sent out
by the Argentine Government. Mr. Kerr was compelled to leave
the steamer ‘ Bolivia’ in the Pileomayo, and with it the greater
part of his collections. The more portable portions—the bird-skins
and the plants—were brought off on mule-back. The birds have
been worked out, and an account of them has been published in the
‘Ibis’ for January 1892; while the Botanical collections are being
investigated at Kew.

In illustration of his remarks, Mr. Kerr exhibited a series of
14 views taken from his own negatives, representing the progress
of the expedition, and the life of the district traversed by it.

176 PROF, F. JEFFREY BELL ON THE [ Mar. 1,

on the north-west coast of Australia, are a number of young
Echinoderms; in many cases it is not possible to assign them a
definite specific place, but to the morphologist they will offer charms
less patent to the systematist.

Among them there is an Ophiurid which is remarkable for the
large size of what are now generally regarded as the plates of the
calycinal area, and which my lamented friend P. Herbert Carpenter
in his valuable essay * called respectively centro-dorsal, under-basals,
and radials. These plates are so well marked that it is quite im-
possible for the most sceptical to regard them as anything else than
the components of a vestigial calyx, and I think their relations to
the rest of the organism are perhaps better shown in the drawing
given herewith than in any previously published figure of an Ophiurid
(Plate XI. figs. 6, 7).

It is certain that the specimen is the young of a species of Pectinura
or of some form closely allied to that genus.

2. CLASSIFICATION OF OPHIUROIDS.

Since the year 1867, when Dr. Ljungman® published his still
valuable classification, no serious attempt has been made to classify
the Ophiuroidea, and it is possible that some doubts remain as to the
relations of the genera that compose that class ; the question whether
the simple-armed Ophioderma or the much-branched Astrophyton
has the more archaic characters is one which systematists have
neither asked nor answered. The majority of naturalists would
probably confess that their impression was that the many-branched
forms had succeeded those with simple arms.

At any rate all are agreed that there are two equivalent orders or
groups—the Ophiure and the Euryale of Johannes Miiller, the
Ophiuride and Astrophytide of Theodore Lyman; if these two
groups are really sharply separated from one another, it will follow
that we must look upon one as derived from the other and now
separated from it by the disappearance of the connecting-links, or
we must suppose that they had long ago a common ancestor and
have since been evolved along distinct lines; the latter is the view
adopted by Prof. Haeckel in his ‘Generelle Morphologie.’

Mr. Lyman, though retaining the bifid division of the class,
recognizes the resemblance of some of the Ophiuride to the Astro-
phytide, for his “group 11.” is called ‘ Astrophyton-like Ophi-
urans.”” Qne striking point in which Sigsbeia and Hemieuryale, for
example, two members of the group, resemble Astrophyton is the
power of rolling their arms. And the function has a corresponding
similarity of structure. In most brittle-stars the “ several ossicles
of the arm have a certain power of movement on one another, but
this is limited by the development of processes and pits analogous
to the zygosphenes and zygantra of the Ophidian vertebrze. In such

1892. ] CLASSIFICATION OF OPHIUROIDs. 177

Ophiuroids, however, as are, like Astroschema, capable of twisting
or twining their arms round a straight Gorgonian, the saddle-shaped
faces are well developed, but the limiting pits and processes are
absent” *. The former plan of structure may be spoken of as
zygospondyline and the latter as streptospondyline; there can be no
doubt that the latter is the simpler, and there is much evidence
to support the view that this simplicity is archaic and not second-
arily acquired. For example, no Astrophytid, all of which exhibit
the streptospondyline type, has the investiture of the central arm-
ossicles differentiated into upper, lower, and side arm-plates; the
madreporites are inconstant in number and position, and pedicellariz,
never known among Ophiurida, may be present.

If the possession of streptospondyline ossicles is an archaic
character in the Astrophytida, it is so also in the Ophiuride. Have
any of them other archaic characters? Ophioscolex has no upper
arm-piates ; Neoplav has a single, incomplete, upper arm-plate ;
species of Ophiomyxa have or have not arm-plates, which, when
present, may be in two pieces; the tentacle-scales, which are so
characteristic of most Ophiurids, are wanting from Ophiomycu
and Ophiobyrsa, are small and single in Neop/az, small and narrow
in Ophiochondrus ; the teeth and *teeth-papille of Ophiobyrsa are
spiniform ; and the teeth-papille are wanting in Ophiomyxa, Ophio-
chondrus, Sigsheia, and Hemieuryale.

Such a combination of characters points to the forms just men-
tioned as the simpler of the class; they might have led to the
vegetatively multiplying Gorgon’s-head or to the more highly
differentiated Ophiothriz.

Before coming to any definite opinion, let us consider the value
of the evidence of the calycinal plates. But little is known of the
development of any streptospondyline Ophiurid ; indeed, all that
we do know is, I think, contained in one passage in Mr. Lyman’s
‘Challenger’ Report. There we read of the young Gorgonocephalus
(p. 252): “ Above there is in the centre a group of six or seven
primary plates, each encircled by a superimposed line of grains.”
Later on, the ‘‘disk-plates” become obliterated. Mr. Lyman’s
observations show that there is no regularity of the plates, which,
as he calls them primary, we may suppose to be the representatives
of the calycinal plates of recent Echinoderm Morphology.

But, after all, this is what may well be expected; now that we
are, as I hope, delivered from the theory of the pelmatozoic”* origin
of the Echinoderms, we may go a step further and recognize, as the
Cystidea teach us to do, that the calyx did not appear at once with
all the diagrammatic regularity that it has retained during the
manifold changes in name that its parts have suffered.

It is, then, among those Cystid-like forms in which a definite
pentamerous arrangement was not permanently established * that we
must seek for the ancestor of the Ophiurid. At present, paleeonto-

178 PROF. F. JEFFREY BELL ON THE [ Mar. 1,

logists have no form known to them which gives any certain
indication of Ophiurid affinities.

The considerations which I have urged will perhaps induce the
student to regard the streptospondyline type as earlier than the
zygospondyline. I have now to show how that type is modified.

Mr. Lyman has shown how the “ Astrophyton-like Ophiurans ”
make an attempt to acquire the saddle-shaped ossicle of the Astro-
phytidz ; we have among the several genera various modifications of
the type which is seen at its simplest in Ophzoteresis.

3. ACCOUNT OF OPHIOTERESIS ELEGANS.

Among the specimens collected by Dr. Coppinger, of H.M.S.
‘ Alert,’ while in the waters of the Western Indian Ocean, were
some examples of a remarkable Ophiurid, the explanation of the
structure of which was quite unattainable at the time when I was
engaged in preparing a portion of the Report published by order
of the Trustees of the British Museum, under the editorship of
Dr. Giinther, F.R.S.

Description of the General, Appearance of a Specimen.

This form is particularly elegant in appearance, owing to the green
colour of the upper surface of the arms and the margins of the disk,
and the ornamentation by light, wavy, meandering lines of the
central portion of the disk with its dark background. Below, the
colour is pale yellow, except in the interradial portions of the disk,
which are dark, and marked by white wavy lines. The contour of
the disk, which is of moderate size in proportion to the arms, is more
or less distinctly pentagonal ; the regularity of the disk is, no doubt,
due to the large size of the radial shields. These, however, are not
apparent from the outer surface, for, like all the rest of the animal,
they are enclosed in a thick softish skin. The oval slits are pro-
vided with teeth and tooth-papille, but there are no mouth-papille.
The arms twist and coil on themselves; at their sides the spines
form mere papilliform projections, owing to the fact that their bases
are encased in the thick investing skin; on the middle line of their
lower surface there is a distinct groove.

Anatomical Details.

Since the publication of Mr. Lyman’s ‘ Challenger’ Report, in
which so many valuable figures were given of the characters of the
ossicles of which the arms of various species of Ophiuroids are made
up, every student of the group turns first to an examination of these
parts of the skeleton.

Those of Ophioteresis are particularly interesting from the ex-
tremely generalized condition which they present. As will be seen
from the drawings (figs. 4 and 5, Plate XI.), the recesses on the adoral
side of the ossicle are excessively shallow, and, in correspondence
with that, the articulating elevations on the aboral side are very slight
and inconspicuous. But, at the same time, it is to be noted that

1892.) CLASSIFICATION OF OPHIUROIDS. 179

the saddle-shaped face of the Astrophytid ossicle is not seen here ;
we have merely a generalized Ophiurid ossicle, without knobs or pits.

The most remarkable character of this Ophiurid (see Plate XI.
figs. 3 and 4) is the complete absence of a ventral plate; no other
existing brittle-star is known to want this plate. The upper plates
are definitely double, and the side-plates, instead of lying flat against
the side of the central ossicles, are wider than long and stand out
from the sides of the arm. The radial shields are very large and
extend almost to the centre of the disk ; they have the form of right-
angled triangles, the hypothenuses of which face, but do not touch,
one another ; there are no other plates on the surface of the disk.

It is necessary to form a new genus for this form, which may be
called Ophioteresis *.

Definition of the Genus and Species.

Ophioteresis is a streptospondyline Ophiurid in which the cover-
ing-plates of the arms are double above, wanting below, and wedge-
shaped at the sides; the radial shields are well developed, and there
are ordinary teeth and teeth-papille.

Ophioteresis elegans has the disk more or less distinctly pentagonal,
of moderate size; arm-spines five. Elegantly coloured, the upper
surface of the arms and the margins of the disk green, the central
portion of the disk dark, with an irregular pattern of meandering
white lines; interradial portions of lower surface of disk dark, with
white lines ; the rest of the lower surface yellow.

Hab. Seychelles, 4-12 fms. In coll. B. M.

From this simple form differentiation would seem to have preceded
along two lines ; there has been an increase in complexity of articu-
lation, associated with the fixation of certain ossicles and spines, or
there has been vegetative repetition and branching with a more
primitive inconstancy and irregularity of anatomical characters.

Around the primitive stock some forms—those which Mr. Lyman
calls the ‘‘ Astrophyton-like Ophiurans”—have remained, such as
Ophioscoler, Ophiobyrsa, Neoplax, and Ophioteresis.

4. Tur Susprvisions oF OPHIUROIDS.

It will perhaps be found convenient to give distinctive names to
the three groups; for brevity’s sake I add here the definition of
Ophiuroids which I ventured to publish last September *.

The Ophiuroidea are caliculate, actinogonidial, eleutherozoic,
azygopodous Echinoderms, in which there is no distinct ambulacral
groove. The “arms” are sharply marked off from the disk, are
very rarely more than five in number, and are sometimes elaborately
branched. The digestive system, which is aproctous, and the gene-
rative are confined to the area of the disk, as is also the specialized
respiratory apparatus, which takes the form of deep clefts.

The Streptophiure are Ophiurids in which the ambulacral

1 Thpnois, alertness. 2 Tic, p. 214

180 PROF. F. JEFFREY BELL ON THE [Mar. 1,

ossicles articulate with one another by means of a more or less
simple ball-and-socket joint ; the covering plates are more or less
regularly developed as superior, inferior, and two lateral, the last of
which bear spines.

The Astrophiurz (s. Cladophiure) are Ophiurids in which the
ambulacral ossicles articulate with one another by means of hour-
glass-shaped surfaces, and are covered by granular deposits in the
thick integument ; the arms may be simple or branched repeatedly.

The Zygophiure are Ophiurids in which the movement of the
ossicles on one another is limited by the development of lateral
processes and pits ; superior, inferior, and lateral spine-bearing plates
are always developed as a covering for the arms, which are always
simple, and incapable of coiling round straight rods.

The Streptophiure.

The following facts justify the vagueness of the definition offered.

a. Upper arm-plates: absent in Ophiomyxa vivipara, double in
O. pentagona, of several pieces in O. flaccida; double in
Ophioteresis ; in Hemieuryale a mosaic of small plates; single
but incomplete in Neoplaz.

. Under arm-plate: absent from Ophioteresis, alone among existing
Ophiuree.

y- Tentacle-scales: absent from Ophiomyxa, Neoplar, and

Ophiobyrsa.

Tooth-papille: absent from Sigsbeia, Hemieuryale, Ophiochon-

drus, and Ophiomy«a.

e. Radial shields are small and short in Ophiobyrsa, small and
irregular in Ophiomyxa, rather large in Ophicteresis, large in
Hemieuryale, and very large in Sigsbeia ; on the other hand,
they are absent from Neoplaz.

The order in which the genera just mentioned should stand to one
another is a question which cannot be discussed now, nor can that
of the relation, clearly enough marked in many points, between the
Streptophiure and the lowest of the Zygophiure: the ‘‘articulating
peg” in Ophioscolex is described as minute; it, Ophiambix, Ophio-
sciasma*, Ophiogeron*, Ophiohelus*, and Ophiotholia have no upper
arm-plates, while in Ophiomyces they are, if present, minute ; in the
three genera marked with an asterisk the arm-ossicles retain the
embryonic character of being nearly divided into two.

In addition to the genera placed under the ‘‘ Astrophyton-like
Ophiurans” of Mr. Lyman—Ophiobyrsa, Ophiomyxa, Ophiochon-
drus, Hemieuryale, and Sigsbeia—to which, of course, must be added
Neoplax, I would place in the Streptophiure the genera Ophio-
myces, Ophiotholia, Ophiohelus, Ophiosciasma, Ophiambix, and
Ophioscolex.

Mr. Lyman says of Ophioblenna, which he places next to Ophio-
scolex, ‘‘ Of its skeleton I am quite ignorant.” I applied, therefore, to
Dr. Liitken, who has charge of the only known specimens, and he

1892. | CLASSIFICATION OF OPHIUROIDS. 181

most kindly informs me the arm-ossicles remind him most of those
of Ophiothrix and Ophiacantha.
The Streptophiurz may be thus arranged :—

A. No under arm-plates ...... 1. Ophioteresis.
B. Under arm-plates imperfect.. 2. Ophiosciasma.
C. Under arm-plates moderate or well developed.
a. No upper arm-plates.
I. No radial shield .. 3. Neoplax.
4. Ophiohelus.
5. Ophiotholia (?).
If. Radial shields present.
6. Ophioscolea.
7. Ophiambia.
8. Ophiogeron.
9. Ophiobyrsa.
10. Ophiomywa (pars).
>. Upper arm-plates minute or formed of scattered plates.
11. Ophiomywa (pars).
12. Ophiomyces.
13. Ophiochondrus.
14. Hemieuryale.
15. Sigsbeia.

It will be gathered that I regard the simple-armed Astrophiuree
as the more archaic, and I propose, therefore, an arrangement of the
genera which is altogether different from that of Mr. Lyman :—

A. Arms simple.
LDisk latee isc epiesks xi 1. Astrotoma.
2. Astronyx.
3. Astrochele.
ii. Disk moderate (about one-tenth of the length of the
v7) Ae eee ee 4. Astrogomphus.
5. Astroporpa.
ili. Disk small, even very small.
6. Ophicreas.
7. Astroschema.
8. Astroceras.
B. Arms branch a few times near their free ends.
9. TLrichaster.
10. Astroclon.
11. Astrocnida.
C. Arms branch much and from near their base.
12. Huryale.
13. Gorgonocephalus.
14. Astrophyton.

These three groups (A, B, and C) correspond to the subfamilies
of Ljungman—Astronycine, Trichasterinz, and Gorgonocephaline ;
and the fact that it should be so, notwithstanding the multiplication
almost by three of the genera of Astrophiurz since 1866, is another

1§2 PROF. F. JEFFREY BELL UN THE [Mar. 1,

proof, if more were needed, of the acumen of the distinguished
naturalist who proposed them.

For the Zygophiurans assistance in classification will be gained
from Ljungman’s well-known work *, and the families may be dis-
posed thus :—

I. Arm-incisures on the disk.
- 1. Ophiodermatide.
a. No dental papillae < 2. Ophiolepedide.
| Il. Arms inserted on ventral surface of disk.
| 3. Amphiuride.
I. Oral papille present.
4. Ophiocomide.
II. No oral papille.
5. Ophiothricide.

B. Dental papille.

5. Tur RELATION oF OrHIOTERESIS TO FosstL Forms.

Zittel places in the suborder Euryalez (= Cladophiure) the genera
Onychaster and Eucladia, of which he says (Handb. d. Pal.
p. 444) that they are “die einzigen fossilen Formen, welche mit
einiger Sicherheit zu den Euryaliden gestellt werden kénnen.” But
Eucladia, as described by Dr. Woodward (Geol. Mag. 1869,
p. 241), has the madreporite on the abactinal surface, whereas all
Ophiuroids have that plate actinal in position. As I purpose to
confine myself for the present to the Ophiuroids, I need not discuss
what is the exact systematic position of Hucladia, beyond urging
that it should be recognized as a form which cannot be placed in
the group Ophiuroidea, as now recognized.

Onychaster has the granular investment which is now found only
in Astrophiuroids, but the articular surface of the arm-ossicles appears
to be rather on the Streptospondyline than the Astrophiuroid (hour-
glass-shaped) type.

Teniaster (Billings, Geol. Surv. Canada, Canadian Organic Re-
mains, dec. iii. p. 80) and Protaster (Forbes, Mem. Geol. Surv.
U. K., dec. i. pl. iv.) are examples of a group of which the most
salient known fact is the absence of ventral arm-plates. I have no
information as to the character of the faces of their arm-ossicles ;
but, as the arms of both are flexible, I have no doubt that their
proper place is with the Streptophiuree.

6. Tue Raprau SHIELDS OF OPHIOMAZA OBSCURA.

In his description of this species Herr Ljungman (op. cit.
p- 333) says, “in dorso scutis radialibus maximis gibboso-carinatis.”’
So far as I can discover, this species has not been seen by any subse-
quent student of the group, and no figure of this very interesting
species has been published.

Its discovery by Mr. Bassett-Smith off the N.W. coast of Australia
(Bassett-Smith Bank, 9 fathoms) extends its geographical range, as
the type was taken off Singapore. The figure which is now given

1 Op. cit.

1892.] CLASSIFICATION OF OPHIUROIDS. 183

(Plate XII. fig. 1) shows very well the definite carination of the radial
shields ; the term carination has been and is applied to keels varying
so much in depth that it is difficult to gauge how slight or how great
it may be in any particular case. Herr Ljungman says ‘‘ Brachia
longitudine diametrum disci ter haud zequantia,” but in the specimen
before me the proportions are nearly 5 to 1 ; I cannot suppose that
this difference is of specific value.

7. OPHIOBYRSA HYSTRICIS.

The largest Streptophiurid found within the British area is the
species so named by Mr. Lyman. Readers of Sir Wyville Thomson’s
‘Depths of the Sea’ will remember that (on p. 123) there is a brief
account of “a very large Ophiurid with thick arms, upwards of
three decimetres long, and a large soft disk resembling that of
Ophiomyxa, to which genus it seems to be allied. The specimens
which have been hitherto procured are scarcely sufficiently perfect
to allow of its being thoroughly worked out.’’ There is not complete
concordance between these measurements and that of Mr. Lyman,
who gives the length of the arm as 187 mm. ; as the diameter of the
dise is 20 mm., the total spread would be very nearly four deci-
metres.

Among the specimens collected by the Rev. W. Spotswood
Green during the dredging-expedition of the ‘ Flying Fox’ off the
S.W. coast of Ireland was one example of this species ; it is a good
deal broken and was, most unfortunately, dried. The figure,
however, now given of it (Plate XII. fig. 2) will give a good idea of its
general appearance. The diameter of the disk is 35 mm., and the
arms must have been at least 310mm. long. As Thomson states that
the specimens he obtained were in a bad condition, it is not improb-
able that he did not preserve his largest but merely noticed its size.

Mr. Green dredged this example in 315 fathoms ; the ‘ Porcupine’
found specimensin 345 fathoms.

2. Description of an Abnormal Earthworm possessing
Seven Pairs of Ovaries. By M. F. Woopwarp,
Demonstrator of Zoology, Royal College of Science,
London’.

[Received February 29, 1892.]
(Plate XIII.)

Abnormalities affecting the genitalia of the Earthworm are of un-
frequent occurrence, and, when such variations occur, they, as a rule,
only affect accessory structures like the spermathece and seminal
vesicles, not essential ones such as the genital glands.

One or two cases have, however, been put upon record in which
the genital glands were themselves affected, although these variations
were but slight ones. One case is described by Benham’, in which
the ovary of the right side was situated on the 12th somite; this
might at first sight appear to be a simple shifting forward of the
ovary, especially as the oviduct and the posterior termination of the
vas deferens of that side are also displaced on to the segment in front
of that on which they are normally situated. But when compared
with the specimen which [ now propose to describe it would appear
more probable that the right ovary of Benham’s specimen does
not correspond with the normal one, but is rather a fresh structure
altogether. Bergh* has also described three abnormal specimens,
viz. two ZL. turgidus and one L. purpureus, which are of great interest
in having undergone an actual reduplication of the ovaries, being
possessed of an additional pair on segment 14, the normal ovaries
being present as usual on segment 13.

The above-cited cases are, as far as I can ascertain, the only re-
corded cases of variations in the position and number of the ovaries
in Lumbricus.

The specimen which forms the subject of the present communi-
cation was a large, well-developed common Earthworm (Allolobo-
phora, sp. inc.), possessing a well-marked clitellum; it was killed
early in November, in which month the genitalia are generally but
poorly developed. With the exception of the ovaries the genital
organs were quite normal.

On the removal of the alimentary canal one immediately noticed a
number of small pear-shaped bodies (Plate XIII. fig. 1, ov.!~7) project-
ing backwards from the mesenteries of the segments 11-17. These
paired bodies are situated one on either side of the longitudinal nerve-
cord, and attached to the posterior face of the mesenteries by their
expanded bases, while their apices project back freely into the cavities

of the somites. The anterior pair (fig. 1, ov.) was borne upon the
mesentery separating the 11th and 12th somites, and immediately
dorsal to the coiled portion of the vas deferens which emerges from
the latter segment. This pair is slightly the largest.

The 2nd pair (ov.”) is situated on the 13th somite, and has all the
typical relations of the ovaries as found in the normal worm; facing
them, and piercing the mesentery 13/14, we find a small pair of ovi-
ducts (ovd.) with well developed receptacula ovorum (r.0.). Side by
side with the latter structures, on the 14th somite, is a 3rd pair (ov.*)
of these conical white bodies, slightly smaller than those in front, but
resembling them in position and structure. On the 15th somite is
situated the 4th pair (ov.*), the members being smaller, of unequal size,
and no longer exhibiting the free tapering apex so characteristic of
the anterior ones. The 5th, 6th, and 7th pairs of these bodies (ov.’,
ov.*, and ov.") lie respectively on the 16th, 17th, and 18th somites, and
show a marked decrease in size; they are relatively rounder and less
regularly developed, the members of each pair being often unequal
in size; further, those on the 17th somite are slightly larger than the
corresponding ones on the 16th.

A rough examination with a hand-lens while the worm was still
fresh showed that the free ends of these structures were composed of
a number of large rounded cells, which at once suggested ova,
especially as the pair of these bodies on the 13th somite possessed all
the relations of the typical ovaries of the normal worm.

The specimen was subsequently clarified in glycerine, and subjected
to a microscopic examination, which entirely confirmed the last ob-
servation. Each of these bodies consisted of a number of rounded
cells, smaller at the broad end, and becoming larger and rounder at
the free end, the tapering apex being composed of a single row of
these large cells (Plate XIII., ov.’~ov.*, 0.), in each of which can be
seen a large round nucleus and one or two nucleoli.

A comparison with the ovaries of a typical worm shows that the
anterior pairs of these structures can in no way be distinguished from
them, either in structure, position on their segments, or in shape.
The four posterior pairs (fig. 2, ov.’-ov.'), however, rather resemble
the ovaries of a very young or immature worm, being rounder and
smaller, composed of smaller cells, and only showing one or two
large round cells so characteristic of the adult ovary, while they are
entirely destitute of that very characteristic free filamentous termi-
nation composed of ripe ova.

From the consideration of the above description, together with a
comparison of the figures given, there can be no doubt that each
pair of these 7 cell-masses is the serial homologue of the single
pair of ovaries of the normal Earthworm; so that this interesting
specimen, instead of possessing only a single pair situated on the
13th somite, is rich in the possession of seven pairs of ovaries,
situated respectively on segments 12 to 18 inclusive.

The condition and shape of the three anterior pairs suggests that
they have already been functional in the discharge of ova into the
body-cavity ; while the four posterior pairs are in a more rudimentary

186 MR. M. F. WOODWARD ON [Mar. l,

condition, and possibly have not thus far been functional, although
the large size of the cells in some of them does not preclude the
possibility of their future maturity.

With regard to the oviducts, although the specimen was most
carefully dissected and thoroughly examined, only one pair of these
ducts was to be seen, and that in the position of the typical single
pair of the normal worm: that is, related to the mesentery between
the 13th and 14th somites, opening into the body-cavity of the
former and on to the exterior on the latter. And neither externally
nor internally could any trace of accessory oviducts be discovered.

It is interesting to note in Bergh’s’ description of the presence of
additional ovaries that he, being unable to discover additional
oviducts, concluded that the ova from the supernumerary ovaries
must necessarily be lost.

This might probably be the case with some of the ova, but if many
were shed into the body-cavity (as would happen supposing all these
ovaries to be functional), it seems possible that some would find their
way through the cireum-neural arcade, which puts the various sub-
divisions of the body-cavity into communication with one another,
and through which the perivisceral'fluid circulates ; and, if so, there
would seem to be no difficulty in their finding their way into the
13th somite, and then out through the oviducts.

Beddard * has recently shown reason to believe that “‘ in Acantho-
drilus the genital funnels and a portion at least of the ducts are
formed out of nephridia,”’ and though not definitely proved for Zum-
bricus, it is probable that they are there formed by a modification of
the same process. In view of this it seems strange that an animal so
rich in ovaries, and with so much material in the way of segmental
organs out of which to fashion oviducts, should have only developed
a single pair.

Passing from Lumbricus to the allied genera, it is not so rare to
find the animal normally possessing two pairs of these glands.
Beddard has described a number of such forms. Thus, Perionyx *
has normally two pairs of ovaries, and is further interesting from
the fact that these structures vary in position from the 9th to the
16th segment. Phreoryctes+** and Urocheta® possess two pairs of
ovaries, situated respectively on segments 12 and 13. Also in
Eudrilus’, Acanthodrilus*, and Phreodrilus® Beddard finds strong evi-
dence for the belief that they also possess an additional pair of ovaries.

Eisen’ in Eclipidrilus has described three pairs of ovaries situated
on segments 9, 10, and 11; this statement is challenged by
Vejdovky *, who maintains that the Oligochzeta possess only a
single pair of ovaries which are never found on the segments behind
the oviducts (see fig. 1, ov.*-ov.”). In like manner the last-named
authority would throw doubt on Lankester’s* description of the two
pairs of ovaries present in Chetogaster.

Among the other genera of the Oligochzta, so far as I am aware,
only one pair of ovaries is developed ; this in the Lumbricomorpha is
usually situated on the 13th somite. But, as has been just pointed
out, at least eight genera may possess more than one pair, and,
further, in many forms the ovaries are developed on segments other
than the 13th.

The following table shows the variation in the position of the ovaries
in those forms that possess two or more pairs of ovaries :—

From this table it will be seen that within the limits of the
Lumbricomorpha the ovaries are found to vary in position from the
9th to the 18th somite, the maximum number thus far known to be
developed being seven pairs.

In front of these we find in my specimen the two typical pairs of
testes developed on segments 10 and 11. As these are without
doubt the serial homologues of the ovaries, the genital glands in this
worm extend from the 10th to the 18th somites.

The genital glands are developed from and under cover of the
peritoneal epithelium, on the posterior face of the mesenteries of the
genital somites. And when we consider that the mesenteries, from
which the germinal epithelium arises, are present for each segment of
the body, and, further, that in most of its organs the worm exhibits
a marked metamerism, it at once suggests itself that in those forms

or individuals possessed of more than one pair of ovaries we have
indications of a metameric reduplication of those organs similar to
that of the testes in the Hirudinea.

A metamerically repetitional disposition of the ovaries is very rare
among worms generally ; in fact, itis only met with in the Platyhel-
minthes, the Cestoda and the Nemerteans both exhibiting it. Setting
aside the Cestoda as highly specialized, we find that the only worms
exhibiting the metameric reduplication of the ovaries are certain of
the Planarians.

Beddard has shown in Eudrilus * that the condition of the oviducts
and their accessory structures, to quote bis words, ‘‘suggests a
comparison with the corresponding organs in the Planarians, from
which group I am disposed (following Lang) to derive the Annelids.”’

The facts which I have herein described and tabulated appear to
me to justify a belief in the potentially reproductive nature of the
individual somites of the Cheetopod body, and to support Beddard’s
suggestion above alluded to.

[Received February 1, 1892. |

When working at the Indian Moths of the family Agaristede,
my attention was drawn by Mr. E. Y. Watson, of the Madras
Staff Corps, to the powers of stridulation possessed by the males of
Aigocera tripartita, Kirby, of which he had brought home a long
series from Burma. This Moth flies at dusk, and the males produce
a loud clicking sound audible at some distance off—click-click-click
at intervals of about a second. This led me to investigate the
subject in this species and in the only other Lepidoptera known to
produce the same sound—certain Butterflies of the genus Ageronia
and other allied genera from Brazil.

The males of . tripartita (fig. 1, p. 189) obviously differ from
those of all the other species of the genus in the possession of a large
patch of hyaline membrane denuded of scales beneath the costa of
the fore wing, and this at once suggests itself as being connected

1 «<The Anatomy of Earthworms,” Q. J. M. 8. n. s. vol. xxx. p. 455.

1892.1 IN CERTAIN LEPIDOPTERA. 189

with the sound produced. When examined with a lens, it is seen that
the wing-membrane is dilated so as to produce a large concavity on
the underside, the membrane being thrown into deep transverse
ridges, strongest immediately below the costa; and when the wing is
cleared of scales it is seen that the costal and subcostal nervures have
all been distorted and curved downward, so as to give increased space
to the dilated and ridged membrane. ‘T'he question then arose as to
the organ that could be used in combination with this structure to
produce the sound. I found that the fore tarsi, instead of being

simply clothed with scales, or with the paired series of spines along
the under surface that are present in many Lepidoptera to give
greater power of attachment when settled, had these spines
immensely developed all over the upper surface of the tarsi, and
that if held extended, instead of folded against the under surface of
the body, the usual method of carrying the legs in Lepidoptera
during flight, the spined upper surface of the tarsi would be exactly »
coincident with the ridged under surface of the wing-membrane, so
that each stroke of the wings in flight would cause the ridges
to pass sharply over the spines and be quite adequate, I think, to
produce the clicking sound. The hind tarsi have the ordinary paired
spines on the under surface, and I suggest that the fore tarsi can be
used to produce the sound, the dilated wing-membrane between the
ridges acting as a sounding-board, for which reason it is denuded of
scales on both surfaces. The use of the stridulation would be for
sexual attraction.

In the closely allied genus Hecatesia, from Australia (fig. 2, p. 190),
the males have a similar but slightly modified structure ; the costal
edge of the fore wing is slightly folded over on the under surface of
the wing, and beneath this, and further from the base of the wing
than in Agocera, is a still broader and more dilated area of hyaline
wing-membrane; this is longitudinally grooved and thrown into very
strong waved ridges on each side of the groove, and in correlation
with the different position of the ridged wing-membrane we find that
it is the mid tarsi that have the spines strongly developed over the

upper surface, and I suggest that the longitudinal fold acts as a
channel for the tarsus, the ridges on each side striking against the
spines. Mr. E. Meyrick informs me that this insect inakes a loud
buzzing sound during flight, and the first time he heard it he thought
a “ humble-bee’’ was buzzing round his hat ; he tells me that the
insect during flight swings rapidly up and down in the air, and he
thought the vibration of the air on the membrane might account for
the sound.

The only other Lepidoptera known to make a similar clicking

Fore wing.

sound are some of the species of Ageronia, e. g. A. feronia, fornax,
amphinome, and arethusa, as was first discovered by Darwin during
the voyage of the ‘ Beagle,’ and confirmed by Wallace, and again by
Fritz Miiller, who says that he also observed it in Hunica margarita
and a small brown butterfly which he could not capture.

Darwin says that when a pair of Ageronia feronia were chasing
each other they produced a clicking sound similar to that produced
by a toothed wheel passing under a spring catch, and that the noise
was produced at short intervals and was audible at twenty yards’
distance. Wallace says the noise was never produced by a single
specimen, but only when a pair were chasing each other, and he
imagined it was in some way produced by the contact of the two
insects; but Bigg-Wither noted that the butterfly settled head down-
wards with its wings outspread, and that if approached it raised its
wings sharply once or twice, producing a whip-like sound, and that
it also made the same sound while on the wing.

Ed. Doubleday examined the butterfly, and found a small mem-
branous sac between the costal and subcostal nervures of the fore
wing, with a structure along the subcostal nervure like an Archi-
medean screw; he very properly disclaimed this structure being
necessarily connected with the sound, and, as Scudder pointed out,
these are merely the swollen base of the subcostal nervure found in
so many Nymphaline and the tracheal vessel in the nervure.

Swinton says that the sound is produced by the costal nervure
of the hind wing, which is ridged like a file, being received into and
rubbing against a small depression of the fore wing ; but, as Scudder

1892. | IN CERTAIN LEPIDOPTERA. 191

again pointed out, this was a structure common to all nervures, and
the ribbing of the nervures is always strongest near the base of the
wings. '

Scudder himself suggests that the sound is produced by the small
erect scales on the superficies of the two wings that overlap rubbing
against each other; but this is obviously inadequate to produce a
clicking sound audible twenty yards off, and it is of universal
occurrence that in the parts of wings that overlap the scales are
short and differently formed, so as to decrease the friction ; though
the rubbing of the wings one against another might be sufficient to
account for the slight rustling or hissing sound made by many of
the Vanesside when held close to the ear.

a, pyriform membranous sac attached to fore wing ; }, chitinous hooks of sac;
ce, chitinous hooks of thorax.

On detaching and clearing a fore wing of Ageronia arethusa (fig. 3),
I found there was a small pyriform membranous sac attached to the
base of the inner margin of the fore wing, open anteriorly, and with
a pair of curved chitinous hooks with spatulate extremities lying
freely in front of it. It was obvious that this could not come into
contact with any of the nervures of the hind wing, and that no
structure attached to the hind wing could act on it; and as there
seemed to be a projection on the thorax in the immediate neighbour-
hood, I cleared and denuded of scales a half insect with the wings
still attached to the thorax, and could then see under a low power
of the microscope that there was a pair of strong chitinous hooks
attached to the thorax, and that when the fore wing was moved up
and down the spatulate ends of the chitinous hooks attached to the
wing played against these, being released when the wing reached a
certain angle, and I suggest that this is the cause of the clicking
sound, the hooks acting as a tuning-fork and the membranous sac
as a sounding-board.

In this case thestructure exists in both sexes, and we must conclude
that there is a mutual wish to attract, and that perhaps it is also
used as a means of inspiring fear, in accordance with Bige-Wither's

experience. I found the structure to be present in Ageronia
Feronia and arethusa.

The other structure to which I wish to draw attention is the dis-
tortion of the hind wing found in the males of certain Noctuina of
the subfamily Ommatophorine, e.g. Patula macrops and the various
species of the genus Argiva, large Moths very common all through the
East. In the females of both Patula and Argiva (fig. 4) the neuration
is of the ordinary Noctuid character. In the males of Patula (fig. 5)
there is a _very large glandular fold covered with long, silky, closely
matted hairs, and with a tuft of long hairs projecting from it, attached
to the costa and folded over ou the upper surface of the wing, and
one notices that instead of the usual nine emarginations of the outer
margin there are only five. But it is not till the wing is denuded of
scales that we see the nature of the change that has taken place ;
when this is done, we see that instead of vein 8 going to the apex
of the wing it is vein 4 that does so, that the functional apex
is really the middle of the outer margin, and that the whole costal
half of the wing has been transformed into the glandular fold,
carrying the nervures with it, perhaps for purposes of nutrition.

In the males of Argiva (fig. 6) we find that this has gone one step
further ; the fold and glandular patch are very small, but it is vein 3
that goes to the apex and there are only four emarginations of the
outer margin, the other veins being represented by small aborted
detached fragments near the base.

The glandular fold is almost certainly a scent-organ, and I suggest
that Argiva once possessed an even larger one than Patula, and
that this fold, becoming detrimental or useless to it, either from
hindering flight or some other cause, has been aborted, carrying the
neuration with it.

charis eupheno and Deilephila nicea from the South of France ;
Deilephila alecto from Syria; Anisotu stigma from N. America ;
and Tricena maxima from India.

The specimens of Deilephila nicea and Deilephila alecto were
reared from pup deposited in the Insect-house by the Hon. Walter
Rothschild, F.Z.S. The specimen of Tricena maxima is the only
one that emerged from several pupz kindly sent by Mr. J. G.
Gammie, of Monghoo, Kurseong, near Darjeeling, through Mr. W. L.
Sclater, F.Z.8. With these pupee many other pupz and cocoons
were sent, but I am sorry to say nearly all emerged en route.
Amongst those that arrived in good condition were some cocoons of
Cricula trifenestrata, from which moths emerged in due course.

Pairings took place, and for the first time I succeeded in rearing the
larvee and obtaining a second brood of this species. The larvee were
very handsome and were reared upon whitethorn. I also succeeded
in rearing the larvee of Hacles imperialis, and the pupz (3) in the
Insect-house are alive and healthy. I had also the larvee of Kacles
regalis, but these I did not succeed in rearing.

Owing to the cold and wet summer of last year collecting was
very difficult, and many species which I have generally easily ob-
tained are absent from this list in consequence.

Mr. Sclater exhibited a flat skin of the Wild Ass of Somali-land
(Equus asinus somalicus), taken from a specimen shot by Mr. J. D.
Inverarity, about fifty miles from Berbera, about eighteen months
ago, and made the following remarks :—

** Mr. Inverarity has kindly sent me the skin of the Wild Ass of
Somali-land (Zguus asinus somalicus), which I now exhibit. It will
be observed that the present specimen differs from that previously
described and figured (P. Z. 8. 1884, p. 542, pl. 50) in having slight
shoulder-stripes, as well as a dorsal stripe. The shoulder-stripe on
the off side is the more distinct of the two. The general colour of
the skin is also not of so deep a grey tint. All the four feet are
banded as in the former specimen.”

Mr. Henry Seebohm exhibited four examples (two males and two
females) of Picus richardsi from the island of Tsu-sima in the Straits
of Corea, and pointed out that one of them had more white at the
tips of the primaries than has yet been found in examples from
Corea. As this is the only alleged difference between P. richardsi
and P. kalinowskii, the latter name, being the most recent, must be
henceforth regarded as a synonym of the former.

Mr. Oldfield Thomas exhibited a mounted head of the Kast-
African Antelope hitherto referred to Oryx beisa, Riipp., but which
he considered to represent a new species.

The specimen described was from the neighbourhood of Mount
Kilimanjaro, and had been generously presented to the National
Museum by Messrs. Rowland Ward and Co., of Piccadilly.

The species was proposed to be called

Oryx CALLOTIS, sp.n. (Plate XIV.)

Size of O. beisa; horns as in that species, but very slightly curved
backwards. Ears long, their tips sharply pointed, and ornamented
with a prominent black tuft, the hairs of which are from two to
three inches in length. Ground-colour of face between the black
markings rich fawn, as dark as the sides of the neck, except just
round the muzzle, where the colour is white. Arrangement of mark-
ings much as in O. besa, except that the black line passing through
the eye runs further down under the throat and in some specimens,

196 MESSRS. BRUNNER AND REDTENBACHER ON [Mar. 15,

as for example in the type, unites below the ramus of the mandible
into that running down from the ear, those of both sides uniting
again on the throat. Throat apparently without a tuft.

Oryx beisa and O. gazella, the only two species at all allied to O.
callotis, both have their ears broadly rounded and quite short-haired
at the tips, and both have the ground-colour of the face white, cha-
racters which readily separate both of these from the species now
described. On the whole O. callotis is more nearly allied to O. beisa,
O. gacella being distinguished from both of them by its throat-tuft,
its larger and more widely expanded horns, and the different cha-
racters of its face-markings.

The type specimen has horns 233 and 22 inches in length, but
the horns are frequently much larger. Sir John Willoughby * says,
“The horns of a female measure from thirty to thirty-two inches ;
those of the male are thicker, but a few inches shorter.”

Mr. Thomas expressed the hope that complete specimens of this
handsome inhabitant of the Imperial British East African Company’s
territory would soon be obtained for the National Collection.

The following papers were read :-—

1. On the Orthoptera of the Island of St. Vincent, West
Indies. By C. Brunner v. Warrenwyt and Professor
J. RepTENnBACHER ’.

[Received February 17, 1892.]
(Plates XV.-XVII.)

At the request of the joint Committee appointed by the British
Association and by the Royal Society to investigate the Fauna and
Flora of the West Indian Islands, Herr Hofrath Carl Brunner von
Wattenwyl has been so good as to undertake the examination of the
Orthoptera obtained in the Island of St. Vincent by Mr. H. H.
Smith, the naturalist sent thither by Mr. F. D. Godman, F.R.S., to
assist the operations of the Committee.

Herr Brunner obtained the help of Prof. J. Redtenbacher, and
the present memoir gives the result of their study of the material
submitted to them.

Herr Brunner, when sending to me the MS. of this paper, re-
quested me to write an introductory notice in our own language ;
I have complied with his wish with the greater pleasure as giving
me an opportunity on behalf of the Committee of publicly thanking
him, as well as Prof. Redtenbacher, for the careful study they
have made of these insects. I have also been able to supplement

1892.] THE ORTHOPTERA OF THE ISLAND OF ST. VINCENT. 197

the information given in Latin by Herr Brunner, as to localities at
which the species have been observed, by some memoranda communi-
cated to me by the collector, Mr. H. H. Smith, to which his initials
are appended.

The collection numbers in all 62 species, of which 19 appear to
be peculiar to the island, 17 of these being here for the first time
named and described.

All the great divisions of the Orthoptera are represented, and in
what may roughly be called the usual proportions, except in one
respect, viz. the paucity of Acridiodea.

The island appears to be favourable for the existence of Orthoptera,
and, as it contains a variety of conditions, the number of species must
be looked on as small compared with what would be found in a
similarly varied area of equal extent in Central or Tropical America.
What the true difference in this respect may be—whether the com-
parative poverty of St. Vincent is great or small—I cannot say, as
I am not aware that the Orthoptera of any one district of Equatorial
or of Central America have been anything like completely
worked up.

Except in the two points I have just alluded to I do not perceive
any points of peculiarity in the Orthopterous fauna of St. Vincent.
The proportion of apterous to winged species seems to be about as
usual, and the number of cosmopolitan or very widely distributed
species is. but small.

I have drawn up a table in order to display the distribution of
the species outside of the island. From this it will be gathered that
29 of the 62 occur in other of the W. Indian Islands, 34 have been
found also in South or Central America, 6 exist in N. America, and
3 have a wide distribution. Of the 26 species found in other W.
Indian Islands (not including the cosmopolitan forms) the majority
occur in Cuba, no less than 20 of the 26 being already known to
be found there.

There is nothing to indicate that these Orthoptera have been
distributed by other means than those that occur in the case ot
continental regions; and Messrs. Brunner and Redtenbacher make
no remarks that would lead us to suppose that they are modified or
varietal forms: the species that are known from elsewhere are not
alluded to as varieties, and the forms that are described as peculiar
are apparently distinguished by characters of normal specific value.

In reference to the comparative poverty of the island in species,
it might be suggested (by those who take it for granted that the
fauna of the island is an entirely derived one) that this poverty is
due to the fact that not all the species that could find subsistence in
the island have been able to make their way thither. But it appears
at least equally probable that the poverty may be due to the re-
stricted range that the small area of the island affords to its
inhabitants.

The paucity of <Acridiodea I see no way of comprehending with
any certainty; but as this division is not only the most numerous
in species elsewhere, but is also the one in which activity is as a

198 MESSRS. BRUNNER AND REDTENBACHER ON __ [ Mar. 15,

rule greatest, it may be that the restricted range is in their case
specially unfavourable. The genus Schistocerca includes two of the
six species of St.-Vincent Acridiodea ; and this genus is remarkable
as comprising one of the few migratory locusts that at times devastate
regions of the Old World; the genus is, however, specially an
American one and it is supposed that the S. peregrina, Ol.—the
migratory locust I am speaking of—is an American insect that
made its way to Africa. It is worthy of note that it is not this
Schistocerca with great powers of flight and self-distribution that
is found in St. Vincent, but two other species, one of which has a
wide distribution in the Antilles and in the continental lands
adjacent, while the other has been hitherto only found in Cuba,
Haiti, and Jamaica, so that both are endemic species of the region
in which St. Vincent is situated.

The Orthopterous fauna of St. Vincent appears to point out that
it is not powers of locomotion that have established certain species
in the island and excluded others, for the earwigs, which are
remarkable from their very feeble powers of flight, are proportionally
better represented in the fauna than the Acridiodea, whose powers
of locomotion are notoriously great. Of the nineteen species
appearing at present peculiar to the island eleven are apterous, and
only eight winged species. It must not, however, be taken for
granted that these nineteen species will ultimately prove to be abso-
lutely limited to the island of St. Vincent. We may indeed feel pretty
sure that some of them will be found in the neighbouring islands,
and until these have been explored it would be premature to attach
much importance to the fact’that the majority of the species peculiar
to the island are incapable of flight. It should also be remarked
in reference to these nineteen species that most of them appear to
be extremely rare, indeed in the case of seven of them only a single
specimen of each has been obtained.

The most remarkable of these Orthoptera is Diapherodes gigas,
the female of which is a gigantic apterous insect, 7 or 8 inches in
length. Another of the most interesting of the Orthoptera of the
island is the Cyrtophyllus crepitans; this is one of the singing
Locustide, allied to the N. American “ Katydids,”’ and is provided
with a powerful musical apparatus. The most abundant Orthopteron
appears to be Orphula punctata; this is a comparatively small
insect, extremely similar to the Stenobothri that are so numerous in
our European fields and commons ; it has, however, no stridulating
organ. ‘The common earwig of the island appears to be Anisolabis
janeirensis.

2. On some Mammals from Mount Dulit, North Borneo.
By Oxprrexp Tuomas.
[Received February 20, 1892. ]
(Plates XVIII. & XIX,).

In 1889 I had the honour of presenting to the Society a paper on
the Mammals of Mount Kina Balu, the highest mountain in Northern
Borneo, and one previously quite unexplored zoologically. Thanks
to the energy of Mr. Charles Hose, a gentleman who has already
distinguished himself by his discoveries in the district of Baram,
N.E. Sarawak, I am enabled now to give an account of some Mammals
collected on Mount Dulit, a mountain about 9000 feet in altitude,
standing at the head of the Baram River.

In the autumn of last year Mr. Hose made a successful expedition
up Mount Dulit, collecting a large number of specimens at altitudes
of from 2000 to 5000 feet, and thereby affording usa very good idea
of the fauna of the mountain.

On the whole, judging from the present collection, it may be said
that the Mammal-fauna of Dulit is very much the same as that of
Kina Balu, there being no instance of a representative but different
species *, while two of the peculiar Kina Balu species reappear here
on Dulit. In all probability, therefore, we may look upon Mr. Hose’s
valuable collection as supplementary to that of Mr. Whitehead, and
may expect that in time most of the members of both the collections
will be found to occur on both the mountains. This is the more
likely as the collections were made at very different seasons of the

Shrews, and this difference between the two collections, while
increasing the number of species, decreases the value of any com--
parisons of the two mountain-faunas.

The Dulit Mammals amount to 14, of which four are new, the
Kina Balu to 21, and, 5 being common to both, the two mountains
together contain, so far as is yet known, a total of 30 species. Of
these the large proportion of 9 are peculiar to these mountains, but
this proportion will probably be reduced as our knowledge of the
mammals inhabiting the low countries near the mountains is extended.
As a contribution towards this knowledge, a nominal list of the
mammals collected by Messrs. Hose and A. H. Everett near the
mouth of the Baram River is appended below. By this it will be
seen that there is a far greater essential difference between the Dulit .
and Baram faunas than there is between those of Dulit and Kina Balu.

Mr. Hose is to be congratulated on the interest and value attaching
to this mountain-collection, and especially on his discovery of the
new Hemigale, a species very distinct from its only ally, and
belonging to an Order, the Carnivora, in which novelties are now
excessively rare.

1. Hemica.e nose!, Thos.’ (Plate XVIII.)

a. 3. 4000 feet. 50/9/91. Type.

Size and proportions very much those of H. hardwickei, although
the skull seems to be rather more lightly built. General colour above
uniform dark smoky brown or black, the bases of the body-hairs
whitish. Sides of muzzle at the roots of the whiskers white, the
corresponding place in H. hardwickei being black ; cheek below eye
and a patch above and behind it grizzled brownish white. Lars
thinly haired, pure white on their inner aspect; edges in marked
contrast to the black crown. Chin white; chest, belly, and inner
sides of limbs proximally smoky yellowish grey. Rest of limbs and
whole of tail black.

Skull (Plate XIX. figs. 1-3) rather sleuderer and lighter than
that of specimens of H. hardwickei of similar age and sex. Muzzle
rather more parallel-sided, not tapering so much anteriorly. Infra-
orbital foramina comparatively large.

Teeth very much more delicate than those of the allied species.
Canines long and slender. P' long antero-posteriorly, double-rooted,
with accessory cusps, like p*, and like the p* of H. hardwickei, in
which p' is simple and single-rooted. Other teeth above similar in
shape to those of H. hardwickei, although markedly smaller, and
with their inner lobes especially reduced. M*, however, is as large
as in H. hardwickei, ©’ and m* being approximately equal. Similarly
below the teeth are smaller and narrower, but p!' and m? are less so
in proportion.

Dimensions (approximate, from skin) :—

Head and body 540 millim.; tail 320; hind foot 78.

Skull: basal length 89; greatest breadth 45:3; interorbital

breadth 18°8; tip to tip of postorbital processes 22°5; inter-
temporal breadth 14:3; palate, length 54, breadth at posterior
corner of p* 25; length of palatine foramina 5:2; greatest diameter
of infraorbital foramina 5:9.

Teeth: combined breadth of upper incisors 11-2 ; antero-posterior
length of p’ 4°6, p* 4-9, p® 5°7, Pp‘ 6:1, m' 4:8, m* 4:3; greatest
transverse diameter of p* 6°6, of m* 5:5.

This striking species is certainly the chief prize of the collection,
as new Carnivores are very rare, and so distinct a new species has
not been described for many years.

That H. hosei is not simply a melanism of H. hardwickei is proved
by the white patches on the muzzle, the white ears, whitish under-
side, and also by the differences in the size of the teeth.

Some animal similar to this, and possibly of the same species, was
seen by Mr. Whitehead on Mount Kina Balu, and it is certainly
very unlikely that an animal of this sort should be confined to one
mountain. We may therefore expect that other specimens of it will
turn up as the mountain-systems of N. Borneo are more thoroughly
explored.

2. HerpEsTes SEMITORQUATUS, Gray.

a. 2000 feet. 23/9/91.

The Museum possesses a specimen of this rare Mungoose from
Baram, besides the type, of which the exact locality in Borneo was
not recorded.

3. RarinoLopaus Luctus, Temm.

a. 9. 4000 feet. 29/9/91.

As remarked by Dr. Dobson, this Bat is a regular highland species,
and seems to occur on all the higher mountains of the Oriental
region.

b. &. 3000 feet. 25/9/91.

c. Immature ¢. 4000 feet. 10/91.

Size much as in Malaccan specimens of 7. ferruginea (Bornean
ones are rather larger), but the tail shorter in proportion. General
colour above dusky olive, with a strong rufous suffusion; head clearer
olive. Back, in fully adult specimeus, with a deep black median
line running from the withers to the rump, but broadening out and
becoming less sharply defined in its posterior half. Under surface
greyish orange, the hairs grey at their bases, broadly washed
terminally with rich olive-yellow. Tail concolorous with the body,
not greyer, as it is so markedly in 7’. ferruginea ; grizzled black and
shining ferrugineous above ; below the central short-haired part is

grey, then laterally there is a broad band on each side of rich olive-
yellow, and the tips are grizzled yellow and black.

Skull and teeth apparently not definitely distinguishable from
those of 7. ferruginea. Zygomatic vacuity large, widely open, about
5 x 2 millim. in the type.

Dimensions :—Head and body (c.) 200 millim.; tail (c.) 140 (the
extreme tip of the tail in the type is apparently wanting ; the tail-
length in 0 and ¢ is 127 and 153 respectively); hind foot 41.

Skull: basal length (c.) 45°5; greatest breadth 27 ; anterior rim
of orbit to nasal tip 22°5; interorbital breadth 15; palate, length
27°8, breadth outside m* 16:4, inside m* 9-7; diastema between i
and ¢ 4-5, between ¢ and p* 1*1; front of i to back of m* 27.

T. montana is most nearly allied to T. ferruginea, Raff., and T.
picta, Thos.’ It is distinguished from both by the colour of its tail,
the former having this member dull annulated grey, and the latter
brilliant rufous; it has alsoa shorter tail than either. From the
former again it is separated by developing in old age a median dorsal
black line, and from the latter, in which the line is present at all
ages, by its less sharp definition, and also the greater uniformity of
the general dorsal coloration.

6. Tupata MINOR, Giinth.

a. &. 4500 feet. 9/10/91.

b. 2. 4000 feet. 10/10/91.

These specimens precisely agree with Dr. Giinther’s types, and
equally differ from the typical 7’. javanica in their smaller size and
pure white bellies.

7. TUPAIA MELANURA, Thos.”

a. 2. 5000 feet. 10/91. Type.

Size very small, less than in J. minor. Fur very soft, close, and
velvety. General colour dark olivaceous grey, finely sprinkled with
yellow, a slight suffusion of dark rufous on the rump and base of
tail. Face rather clearer olive ; a short orange-coloured stripe above
and below the eye, but not passing backwards towards the ear. No
pale shoulder-stripe present. Belly-hairs grey basally, washed termi-
nally, from chin to anus, with bright orange. Outer sides of limbs like
back, inner sides like belly ; upper surfaces of hands and feet nearly
black. Tail furred and coloured like body for about its basal inch
and a half above and half inch below, but beyond that it differs from
that of all other species by being quite cylindrical and short-haired,
the hairs being closely adpressed and not forming a terminal pencil;
in colour the short-haired part is deep jet-black throughout.

Skull (Plate XIX. figs. 4 and 5) delicate, smooth, and evenly
rounded. Zygomatic foramen reduced to a minute oval opening,
which will scarcely admit the point of a needle. Palate without
vacuities.

Teeth. 1 nearly as long as i’ ; double-rooted. Canine and Pp” also

both double-rooted. Lower teeth as in 7. minor except that ¢ is
smaller and j3 and p? larger in proportion, so that the tooth-row
appears as a whole to be more uniform.

Dimensions (approximate, from skin) :—

Head and body 125 millim. ; tail 136; hind foot 29-7.

Skull: basal length 30; greatest length 36, greatest breadth 17:7 ;
nasal length 13 ; interorbital breadth 10 ; intertemporal breadth 14 ;
palate, length 18°2, breadth outside m* 9-6, inside m* 5-4; diastema
between i? and ¢ 2-0, between ¢ and p* 0:4. Vertical length of i' 2:1,
of i? 1-7, of ¢ 1°5. Front of i' to back of m* 17-7.

This beautiful little species is the most interesting of the Tupaie
obtained, as it forms a connecting-link with the two species belonging
to the genus Dendrogale. That genus was founded by Dr. Gray and
recognized by Dr. Anderson in his recent review of the Tupaiide
mainly on account of its cylindrical tail, black-and-white banded
cheeks, and the absence of the usual shoulder-stripe. Now 7. mela-
mura on the one hand has a tail even slenderer and more cylin-
drical than D. murina and D. frenata, and has no shoulder-stripe,
while on the other its face-markings are quite as in Tupaia. One
character, however, distinguishes Dendrogale, or at least D. frenata,
from all the Tupaie, namely the extremely small size of the claws,
both fore and hind; and so far as this character is concerned
T. melanura is a true Tupaia, as it has claws quite as large in
proportion as the other species. For the present therefore I consider
it to be a T'upaia, and leave the validity of “ Dendrogale” as an open
question to be settled when further, and especially spirit-, specimens
are obtained.

a. 9. 4000 feet. 10/91.

9. Sciurus prevosti1, Desm.

a,b. gS Q. 5000 feet. 10/91.

Both these specimens are of the grey-backed form of this species,
like specimens a—c of the Kina Balu collection.

10. Sciurus noratus, Bodd.

a. 3. 3500 feet. 20/9/91.

This specimen, like the Kina Balu examples of the species, is of
the blue-bellied type, and Mr. Hose remarks that he obtained 13
skins, all like this one, during the same month.

b. 2. 5000 feet. 10/91. Type.

About the size of Sciurus lokriah, Hodgs., or rather smaller ;
decidedly larger than S. tenwis, Horsf. General colour above plain
olive-grey, grizzled with yellow, but not so finely asin S. ¢enuis.

without the rufous suffusion characteristic of S. tenuis. Cheeks,
anal region, and basal inch of tail below brilliant rufous. Chest and
belly greyish white, the hairs grey basally, and dirty white termi-
nally. Tail-hairs broadly annulated with black and pale yellow.

Dimensions of the type, an adult female in skin :—

Head and body 205 millim.; tail, without hairs, 144; hind

Skull: basal length (c.) 37; bregma to nasal tip 32; greatest
breadth 25°6 ; nasals, length 132, combined breadth 7 ; interorbital
breadth 15; diastema 10°6; palate, length 22, breadth outside m'
10:2, inside m! 6 ; front of p* to back of m® 7:4,

This Squirrel belongs to a group of Oriental species characterized
by their dull grizzled olive-grey colour, unstriped sides, and annu-
lated black and yellowish tails. For ornamentation some of the
species have rufous patches on the head, shoulders, hips, or tail, but
some are quite without them, and in all they vary very much in their
development. To this group belong S. chinensis, Gr., S. lokriah,
Hodgs., S. lokrioides, Hodgs., S. tenuis, Horsf., 8S. lowii, Thos.,
S. philippinensiz, Waterh., and others. From all of these 8. brooket
is readily distinguished by its bright rufous cheeks and base of tail,
and by its size, in which respect it considerably exceeds S. tenuis and
S. lowii, and falls short of all the rest. S. modestus, Miill. & Schl.,
I agree with Dr. Jentink * in considering synonymous with S. tenuis,
as not only is Malacca the first-mentioned locality for it, but the
figures both of animal and skull are identical with typical Malaccan
and Singapore specimens.

Of other Bornean species S. jentinki, Thos., is smaller and much
more yellow above, while S. everetti, Thos., has a much more
elongated muzzle, and neither of them has the rufous markings of
S. brookei.

I have taken the liberty of naming this species in konour of His
Highness the Rajah of Sarawak, in whose service Mr, Hose is, and
by whose active encouragement he has been enabled to do so much
valuable zoological work in that interesting territory.

This species must be very common on Mt. Dulit, as Mr. Hose
states that he obtained 20 specimens of it while he was there.

that mountain.

birds in the island of St. Thomas. This new species has a brown
style of coloration which is characteristic of many Timeliine birds,
but it seems to find its nearest ally ina Malayan genus Crateroscelis
of Malacca and Borneo. It differs, however, from that genus in
certain evident characters, which may be diagnosed as follows :—

AMAUROCICHLA, gen. nov.

Similar to Crateroscelis, but distinguished by the shape of the
wing, the first primary being nearly as long as the second. Addi-
tional characters are:—The bill is as long as the head, and rictal
bristles are absent, while the tail-feathers are somewhat acuminate.
The type is :—

AMAUROCICHLA BOCAGII, sp. nov. (Plate XX. fig. 1.)

Adult. General colour above uniform chocolate-brown, the
wings and tail a little darker than the back; lores and sides of
face dark brown like back, the ear-coverts slightly rufescent, like
the sides of the neck ; cheeks and throat whitish, with a slightly
indicated malar line of rufous; lower throat and rest of under
surface of the body rufous; the abdomen isabelline; under wing-
coverts isabelline; quills sepia-brown below. Total length 5
inches, culmen 0°8, wing 2°55, tail 1°55, tarsus 0°95.

Hab. San Miguel, west coast of St. Thomas, West Africa.

While describing this interesting species I may add the diagnosis
of another Timeliine bird recently acquired by the British Museum,
which also seems to be undescribed, and for which I propose the
following name :—

TURDINUS MOLONEYANUS, sp. nov. (Plate XX. fig. 2.)

Adult. General colour rufous brown, inclining to chestnut on the
lower back, rump, and upper tail-coverts, as well as on the wings;
primaries dusky, externally light rufous; tail-feathers light rufous
brown, externally shaded with chestnut; crown of head slightly
more dusky than the back; an indistinct line of ashy grey above
the eye, and the feathers below the latter ashy; ear-coverts brown ;
throat and under surface of body tawny rufous, more rufous on the
fore neck, chest, and sides of body, the latter inclining somewhat to
reddish brown ; thighs like the abdomen ; under tail-coverts light
chestnut ; axillaries and under wing-coverts tawny rufous; quills
dusky below, rufescent along the inner web. Total length 6-6 inches,
culmen 0°85, wing 2°7, tail 2°5, tarsus 1-0.

Hab. Gold Coast.

The typical specimen was presented to the British Museum by
Sir Alfred Moloney, who procured it during the time that he was
Governor of the Colony.

1892.] DR. H. GADOW ON THE CLASSIFICATION OF BIRDS. 229

4, On the Classification of Birds. By Hans Gapow, M.A.,
Ph.D., F.Z.S., Strickland Curator and Lecturer on
Advanced Morphology of Vertebrata in the University
of Cambridge.

[Received March 12, 1892.]

By undertaking, in 1884, the continuation of the part ‘ Aves’ of
Bronn’s ‘Klassen und Ordnungen des Thier-Reichs,’ I became
pledged not only to a descriptive account of the anatomical structure
of birds, but also to a systematic treatment of this Class with its
Orders.

The anatomical portion has been written with the view of ab-
stracting therefrom aclassification. In the meantime (after Huxley,
Garrod, Forbes, Sclater, and Reichenow’s systems) have appeared
several other classifications: one each by Prof. Newton, Dr. Elliott
Coues, Dr. Stejneger, Prof. Fuerbringer, Dr. R. B. Sharpe, and two
or three by Mr. Seebohm. Some of these systems or classifications
give no reasoning, and seem to be based upon either experience in
ornithological matters or upon inclination—in other words, upon
personal convictions. Fuerbringer’s volumes of ponderous size have
ushered in a new epoch of scientific ornithology. No praise can be
high enough for this work, and no blame can be greater than that it is
too long and far too cautiously expressed. For instance, the introduc-
tion of “ intermediate ” groups (be they suborders or gentes) cannot
be accepted in a system which, if it is to be a working one, must
appear in a fixed form. In several important points I do not agree
with my friend ; moreover, I was naturally anxious to see what my
own resources would enable me to find out. This is my apology for
the new classification which I propose in the following pages.

The author of a new classification ought to state the reasons which
have led him to the separation and grouping together of the birds
known to him. This means not simply to enumerate the characters
which he has employed, but also to say why and howhe has used them.
Of course there are characters and characters. Some are probably
of little value, and others are equivalent to half a dozen of them.
Some are sure to break down unexpectedly somewhere, others run
through many families and even orders; but the former characters
are not necessarily bad and the latter are not necessarily good. The
objection has frequently been made that we have no criterion to
determine the value of characters in any given group, and that
therefore any classification based upon any number of characters
however large (but always arbitrary, since composed of non-equivalent
units) must necessarily be artificial and therefore be probably a
failure. This is quite true if we take all these characters, treat them
as all alike, and by a simple process of plus or minus, i. e. present
or absent, large or small, 1, 2, 3, 4, &c., produce a “ Key,” but
certainly not a natural classification.

To ayoid this evil, we have to sift or weigh the same characters
every time anew and in different ways, whenever we inquire into the

230 DR. H. GADOW ON THE [Mar. 15,

degree of affinity between two or more species, genera, families, or
larger groups of creatures. ;

This I have tried to do in a manner hitherto not applied to birds ;
it may have been done by others, but they have not published any
account of this process. Certainly it has not been applied throughout
the whole Class of Birds.

I have selected about forty characters from various organic systems
(see Appendix, p. 254), preferring such characters which either can
be expressed by a formula or by some other short symbol, or which,
during the working out of the anatomical portion of Bronn’s ‘ Aves,’
have revealed themselves as of taxonomic value, and of which I have
learnt to understand the correlation, determining causes, and range of
modification. Other characters, perhaps too complicated, too variable,
or last, but not least, too imperfectly known in many birds, are left
out or reserved for occasional employmeut.

Of my 40 characters about half occur also in Fuerbringer’s table,
which contains 51 characters. A number of skeletal characters I have
adopted from Mr. Lydekker’s ‘ Catalogue of Fossil Birds,’ after having
convinced myself, from a study of that excellent book, of their
taxonomic value. Certain others referring to the formation of
the rhamphotheca, the structure and distribution of the down in
the young and in the adult, the syringeal muscles, the intestinal
convolutions, and the nares, have not hitherto been employed in
the Class of Birds.

Groups of birds, arranged in bona fide families, sometimes only
genera of doubtful affinity, were compared with each other—
each family with every other family or group—and the number of
characters in which they agree was noted down in a tabular form.
Presumably families which agree in all the 40 characters would be
identical, but this has never happened. There are none which differ
in less than about 6, and none which agree in less than 10 points.
The latter may be due to their all being birds. It is not easy to
imagine two birds which would differ in all the 40 characters.

In another table all the families were arranged in lines accord-
ing to their numerical coincidences, aud attempts were made to
arrange and to combine these lines of supposed affinities in tree-like
branches !. These attempts are often successful’, often disappointing *.

1 Many calculations are obviously unnecessary: for instance, the comparison
of Geese with Parrots or Passeres ; Steganopodes with Swifts, Rollers, Trogons,
&e.

2 For instance, Pteroclide agree with Limicole and with Columbz in about
29 points, with Alex and with Gallidz in 24, with Ralli in 21, with Lari only
in 18.—Again, Lari agree with Alcx and with Limicol in 33 or 34; Limicolz
agree with Alex, Lari, and Ralli each in 33, with Pterocles and Columb in 30
or 31, with Gallidz in 26. Combination of these lines shows that Lari and
Pterocles are widely divergent from each other, while they each separately agree
closely with the Limicolx; in other words, Lariand Pterocles are specialized in
two different directions as terminal divergent branches of one common
Limicoline stock.

3 The more generalized, or rather the less specialized, two given groups are,
the more characters they will probably have in common, and similar false
affinities will appear the more likely the greater the diversity of organic modifi-

1892.] CLASSIFICATION OF BIRDS, 231

Of course this merely mathematical principle is scientifically faulty,
because the characters are decidedly not all equivalent. ~ It may
happen that a great numerical agreement between two families rests
upon unimportant characters only, and a small number of coincidences
may be due to fundamentally valuable structures, and in either case
the true affinities would be obscured. This it was necessary to
inquire into. But at any rate I obtained many hints from this
simple mode of calculation, indicating the direction which further
inquiry should take.

The Psittaci may serve as an example of my mode of sifting
characters.

According to the numerical agreement of the 40 characters
employed generally, we have the following table :—

Psittaci agree with Coccyges in 31 points, with Pici in about 29,
with Coraciide 25, Falconidee 25, Striges 22, Bucerotidee 22,
Gallidz 21, against 19 points of difference.

A previous line of investigation had revealed the fact that the
Coccyges and Gallidz are intimately connected with each other
through Opisthocomus. This knowledge obviated further inquiry as
to the affinity between Psittaci and Gallide.

Of the 26 positive points not less than 19 are common to
Falconide, Psittaci, and Coccyges. In the remaining 7 points
Psittaci and Falconide agree together against Coccyges, namely
nestlings, downs of young and adult, fifth cubital, temporal fossa,
fleshy tongue, convolutions of intestines. Most of these characters
seem important, especially the woolly nestlings, considering that
Psittaci breed in holes, and agree in the convolutions in spite of the
totally different food.

On the other hand, the sifting of the 14 negative characters shows
that in 13 of them the Parrots agree with Cuculide or with Muso-
phagide, or with both, and differ along with the Coccyges from the
Falconidz. The syrinx is an absolute specialization. Fuerbringer
remarks that powder-downs, ceroma, and beak speak for Falconidz
against Coccyges. Again, Psittaci and Falconide differ greatly in
the formation of the furcula, in nearly the whole of the muscular
system, and in the bones of the wings and legs.

Conclusion.—The Psittaci are much more nearly allied to the
Coccyges than to the Falconide, and of the Coccyges the Muso-
phagide are nearer than the Cuculide because of the vegetable
food, ventral pterylosis, presence of aftershaft, tufted oil-gland,
absence of vomer, truncated mandible, and absence of ceca.

II. Comparison of Psittaci, Coraciide, and Coccyges, based by
Fuerbringer chiefly upon the pterylosis, anterior lateral pro-
cess of the sternum, procoracoid process, clavicular connexion,
hypotarsus, shortness of metatarsus, many muscles of the
shoulder and thigh. He observes, however, that the greater
number of characters is against this relationship. The com-
parison made by me is given in the Table now before us (see
p- 233).

III. Comparison of Psittaci and Striges. 22 characters agree,
18 differ ; the latter are :—

Toes. . . Striges more primitive, although ectamphibolic.
Downs of adult in Striges only upon apteria.

aor } Parrots specialized.

These differences are important enough, not only on account of
their number but also on account of their value, to remove Psittaci
and Striges far from each other. Striges are perhaps on the whole
more primitive, but both groups have been specialized in two different
directions. Some of the agreements (e. g. absence of a bony tibial
bridge, the sternal configuration) are most likely referable to the
numerous organic links which connect the Coraciiformes and Cuculi-
formes with each other.

IV. Comparison of Psittaci with Pici. Curiously enongh these
two groups have many characters in common, namely 29
against 11. The differences are :—

1. Woolly nestlings, although both breed in holes.
2. Presence of downs in adult.

3. Dorsal pterylosis.

4. Large aftershaft (intermediate are, however, Capito and

Indicator).

5. Aquinto-cubital.

6. No vomer.

7. Flexor tendons of toes.

8. Procoracoid process.

9. Cervical heemapophyses.
10. Syrinx.

11. Intestinal convolutions.

Of these differences Nos. 1, 2, 6, 7, 8, 10, and 11 are of great
importance.

Of the 29 positive characters or resemblances the form of the
spina externa sterni alone is remarkable, otherwise nothing which
cannot be explained equally well by the affinity of the Psittaci to
the Coccyges or to the Coraciiformes, of which latter order,
moreover, the Pici are an offshoot. The resemblances between the
Pici and Psittaci have therefore chiefly to be looked upon as con-
vergent analogies.

Final Conclusion.—The sifting of all these characters shows an un-
doubtedly close affinity between the Psittaci and Coraciide, but less
intimate than with the Coceyges. The latter are, however, closely

1892.] CLASSIFICATION OF BIRDS. 235

related to the Coraciidz, and are (as indicated by the Opisthocomus-
Gallidz connexion) the lowest of the three groups of Psittaci, Cora-
ciide,and Coccyges. Cuculidz, as well as Coraciid, are zoophagous,
chiefly insectivorous. The Striges, as a lateral branch of the lower
Coraciine stock, explain the considerable number of characters which
connect the Striges with the Coccyges, 28 against 12, and with the
Psittaci, 22 against 18. In our hypothetical tree the Psittaci would
combine with the Coccyges into one bigger branch—Cuculiformes ;
the Psittacine twig to stand between that of the Musophagide and
looking towards the branch of the Striges, which again come out of
the bigger branch of the Coraciiformes. This big branch and that
of the Cuculiformes would ultimately combine into a still bigger
branch ; below this bifurcation would come off Opisthocomus and
lower still that of the Gallide. Thus the Psittaci permit us a glimpse
at a large part of the Avine tree, namely at that big branch which
downwards points towards the Galliformes and towards the Gallo-
Ralline and Rallo-Limicoline region of the tree, while the same
branch upwards ends not only in all the so-called Picarize but also
in the Pico-Passeres.

The laborious process exemplified in these comparisons was
applied to all the families and was not without results, because certain
families were gradually found to assume a central position
towards which a number of others gravitated. Thus, for instance,
the Coraciide had to be compared with not less than 10 other
families ; the Gallide with 8, &c. Notoriously difficult forms, as,
for instance, Trogons and Colies, naturally caused more trouble
than others, since the number of comparisons had to be increased.

The result of all this is the following classification. In the mode
of denomination of the various smaller and larger combinations I
have followed Fuerbringer’s plan. I am sorry that my classification
does not bear greater resemblance to his, but nobody who has really
studied Fuerbringer’s work will fail to perceive that I stand on my
friend’s shoulders, or rather on his two fundamental volumes in
addition to my own work.

The subfamilies, which have been mentioned whenever desirable,
end in ine. The families end in ide.

The Families are combined into Suborders, indicated by substantival
names. The Suborders are combined into OrpErs, ending in formes,
with a Latin substantive stem. The Orders could, if necessary, be
combined into Paya, ending in morphe, with a Greek substantive
stem; these would correspond with Fuerbringer’s Orders, while
my Orders are equivalent to his Suborders.

The whole of the Class Aves has been divided into 2 Subclasses,
to which the names of Archornithes and Neornithes have been given,
the equivalent names of Saururz and Ornithure being objectionable,
because there is no difference in the skeletal part of the tail of
Archeopteryx and that of the Ratite, Crypturi, and Hesperornithide.
The Neornithes are separated into the two Divisions of Ratite and

236 - DR. H. GADOW ON THE [Mar. 15,

Carinate. These names are likewise open to objection, but they have
become household terms and they serve a practical purpose.

Many attempts have been made to brigade together two and two
of my orders into combinations intermediate in value between Orders
and Phyla—for instance, Tubinariformes and Ardeiformes, Charadri-
formes and Columbiformes—but ultimately these attempts have been
abandoned as of little practical value. They are, however, conducive
to the construction of the much searched for phylogenetic tree, but
the very existence of such a single Avine tree is a problematic
idea.

Under the heading of each group, be it subfamily, order, or sub-
class, is mentioned a variable number of characters. The sum total
of these constitutes more than a diagnosis. The single characters
themselves are not necessarily all those which have led to the
establishment of the group in question, but the sum total of the
characters mentioned has been thus arranged, first that it applies to
all the members of the group, secondly that it does not occur again
in those of any other group.

2nd Division. NEQRNITHES CARINATZ.

This division comprises all those Neornithes to which the sum cf
characters descriptive of the Ratitee does not apply.

As a rule the Carinatz are described as birds possessed of a carina
sterni; an acrocoracoid process; separate scapulz and coracoids,
which form an acute or a right angle; complete furcula ; ischiadic
foramen ; single-headed quadrate; a vomer which is not fused with
the neighbouring bones of the palate.

The existence of such forms as Crypturi, Didus, Ocydromus,
Stringops, Hesperornis, &c., does not perinit the employment of these
characters to differentiate the Carinate from the Ratite. These
are reasons sufficient to contest the validity of these two divisions,
which are, however, retained more for the sake of convenience than
on the ground of demonstrable facts.

The Secretary read the following report on the additions to the
Society’s Menagerie during the month of March 1892 :—

The total number of registered additions to the Society’s Mena-
gerie during the month of March was 107, of which 57 were by
presentation, 17 by birth, 23 by purchase, 4 by exchange, and 6
were received on deposit. The total number of departures during
the same period, by death and removals, was 96.

Among the deaths, I regret to have to announce that of the last of
the Society’s stock of Giraffes—a male, purchased Jan. 27th, 1879.
We are now, therefore, for the first time since the arrival of the four
original Giraffes on the 24th of May, 1836, without any representa-
tive of this Mammal in our series. Nor does there seem to be at
present much chance of our being able to supply the deficiency.
Owing to the closure of the Soudan by the Mahdists, the supplies of
this and other large African Mammals, which were formerly ob-
tained vid Cassala and Suakim, have ceased, and, so far as [ can
make out, with the exception of a single old female (for which an -
exorbitant price is demanded), there are now no living Giraffes in
the market.

From the table which I now exhibit, it will be seen that there
have been 30 individuals of the Giraffe in the Society’s Gardens since
1836, of which 17 have been born there, and 13 have been acquired by
purchase. Of these 30, one was presented to the Royal Zoological
Society of Ireland in 1844; five have been sold at prices varying from
£450 to £150, and the remainder have died in the Gardens.

Mr. Sclater called attention to two mounted heads of Swayne’s
Antelope’ (Bubalis swaynei), which had been kindly lent to him by
Messrs. Rowland Ward & Co. . These were the specimens obtained
by Mr. T. W. H. Clarke and Colonel Paget, and other members of
the same party, which were alluded to in the ‘ Field’ of March 26,
1892 (vol. Ixxvi. p. 432), and one of which was there figured.

Mr. Sclater remarked that the heads now exhibited were evi-
dently those of a male and female, the male in this, as in other
species of the genus Bubalis, differing in the stouter and thicker
horns.

Mr. Sclater stated that Prof. Giglioli, of Florence, had kindly
sent him a coloured drawing of the ‘head of an Antelope obtained
by Count August Boutourline and Dr. Traversi in Shoa in 1882,
which had been referred by Dr. Giglioli (Ann. Mus. Civ. Genova,

1 See above, p. 98.

258 MR. E. A. SMITH ON THE (Apr. 5,

ser. 2, vi. p. 19) to the Hartebeest of South Africa (Bubalis caama),
but that it was evident, from the shape of the horns and colour of
the hairs, that this specimen also belonged to B. swaynei.

In reference to some remarks that had been made upon his usage
of ‘‘ Bubalis”’ instead of “* Alcelaphus” for this group of Antelopes,
Mr. Sclater pointed out that ‘ Budalis” of Lichtenstein was pro-
posed in 1814 (Mag. d. Gesellsch. nat. Fr. vi. p. 152), two years
before ‘* Aleelaphus’’ of Blainville, and had been constantly used
by Sundevall, Peters, and other writers, so that it had undoubtedly
good claims to priority.

A note was read from Professor Jeffrey Bell regarding the habitat
of Bipalium kewense. ‘This interesting Planarian, first found in Kew
Gardens, had been observed in very various parts of the world. In
only one case, however, did the circumstances of its discovery make
it possible that the worm was indigenous to the place where it was
met with. ‘That one place was Samoa, where Mr. J. J. Lister found it
under stones in the bush. Mr. Fletcher, in communicating this
fact to the Linnean Society of New South Wales (sce Zool. Anzeig.
1891, p. 139), had expressed the opinion that there was little ground
for supposing that the species was indigenous in Samoa. Further
reason, however, for supposing that Samoa may be one of the
places in which the worm is indigenous was to be found in the fact
that Mr. R. B. Leefe had recently collected the same worm in
Tongatabu. Prof. Bell had learnt from the Director of the Royal
Gardens, Kew, that though no plants had, to the Director’s know-
ledge, been received directly from Tongatabu, exchanges had been
made with Fiji. It might be urged that the probability of the group
of islands just named _ being the original home of the species was, on
the whole, increased by the facts now stated.

The following papers were read :—

1, On the Land-Shells of St. Helena. By Encar A, Suiru.
(Plates XXI. & XXII.)
[Received March 2, 1892.]

Last year I had the honour of presenting to the Society an account
of the marine Mollusca of St. Helena. I now propose to introduce
to its notice-some remarks upon the terrestrial fauna of that island.
Like the former, the present report is based chiefly upon collections
made by Capt. W. H. Turton, R.E., and presented to the British
Museum. The collection is the most complete that has ever been
made, and contains examples not only of most of the known species,
but also of as many as eleven undescribed forms, a proportion of
more than one third of the entire fauna. Our best thanks are due
to Capt. Turton for the labour of getting together such an interesting

collection, and for the careful notes regarding localities which accora-
pany the specimens.

The most complete account of the terrestrial fauna’ of St. Helena
hitherto published is that given by Mr. Wollaston in his work
‘Testacea Atlantica,’ published in 1878. He there enumerates 29
species of Land-Shells, of which 9 at least must be regarded as
introductions since the discovery of the island 390 years ago. Some
of these species—for example, Limax gagates, Vitrea cellaria, V.
alliaria, Helix pulchella, H. aspersa, and Pupa umbilicata (=helen-
ensis, Pfr.)—were doubtless introduced along with European shrubs
and plants. Patula pusilla probably was imported from Madeira,
the Canary Islands, or the Azores, where it is very abundant ; and
the two remaining species, Stenogyra compressilabris and Acicula
veru, upon which some remarks will be made at the end of this
paper, are evidently West-Indian forms. With regard to the twenty
indigenous species mentioned by Mr. Wollaston, some, in my
opinion, are merely varieties and not specifically distinct. After a
careful study of all the forms, including the eleven new species
now described, the total number of indigenous species may be
estimated at twenty-seven. Of these, seven are living on the island
at the present time, eighteen have become extinct since the destruc-
tion of the primeeval forests, and two are found both recent and semi-
fossil.

A great deal has been written upon the relationship of the fauna
of St. Helena with regard to other parts of the globe, and an
interesting résumé of this subject is given by Mr. Wallace in his
work ‘ Island Life,’ pp. 28)-297.

Professor Forbes many years ago, from a study of the Mollusca,
hazarded the theory of a possible ancient connection of St. Helena
with South America, This view, however, was vigorously rejected
by Wollaston, Jeffreys, and others, and, considering the present
isolated position of the island, the actual enormous depth of the
surrounding ocean, and other cogent reasons”, this theory certainly
does appear unsupportable. There is, however, a greater resem-
blance between the shell-fauna of the two localities than was recog-
nized either by Forbes or Wollaston ; and the occurrence of a species,
discovered since they investigated this subject, and more resembling
a group (Zomigerus) which is exclusively Brazilian in distribution
than avy other, together with the reasons which influenced Forbes,
would seem to indicate that country as the probable source whence
some of the indigenous but now extinct species, or their ancestors,
originated. How they were transmitted is a hopeless problem to
solve, and although drift-wood, carried by oceanic currents, is
doubtless answerable for a good deal in the way of distribution, the
subject must apparently ever remain one of mere speculation. It
has been stated by Mr. Wollaston that the large Bulimus auris-
vulpina is represented in the Solomon Islands and New Zealand by

species which have much the same type of form ; but this supposed
resemblance, in reality, proves to be less, on a careful comparison of
the two types, than one at first would imagine. Perhaps the most
striking similarity to Pacific forms occurs among the Patule. Such
species as P. radiella, Pfr., P. multilamellata, Garret, P. acuticostata,
Mousson, and others from the Polynesian Archipelago are exact
representatives of the Endodonte, or toothed group of Patule, from
St. Helena. Still, although these Pacific forms are certainly of the
same type, we must also remember that the same form of Patula
occurs in the island of Fernando Noronha, namely, P. quinguelirata,
Smith, and possibly also on the adjacent mainland of Brazil itself,
although its presence there has yet to be discovered.

In the following complete list of the indigenous species references
are not given, as they are obtainable by consulting Mr. Wollaston’s
work. In conclusion I propose to discuss one or two of the intro-
duced species.

A. Indigenous Species.

1. VirrEA MELLIss11 (Wollaston).

This minute species, which is known to me only by description, is
possibly an introduction. :

Patuxa (without teeth).

2. Paruta spurca (Sowerby). (Plate XXI. figs. 1, | a.)

This species was unknown to Mr. Wollaston, and consequently
being misled by the somewhat poor figure given by Forbes, he has
placed it in the genus Hyalina (=Vitrea). The examination,
however, of a number of specimens, some received from Mr.
Alexander, who furnished Forbes with his examples, others from
Capt. Turton, proves that it should be located in the group
Patula. Sowerby’s description heing so brief, I think it advisable
to recharacterize it, thus :—

Testa anguste umbilicata, suborbicularis, tenuis, albida, rufo-
variegata, haudnitida ; spira parum elevata,ad apicem obtusa ;
anfractus 5, convexiusculi, regulariter et lente accrescentes,
lineis incrementi tenuibus confertis fleruosis obliquis striati,
ultimus ad peripheriam rotundatus, antice haud descendens ;
apertura late lunata, simplex, haud dentata vel lirata ; peri-
stoma tenue, margine columellari leviter expanso et reflexo.

Diam. maj. 5 millim., min. 44, alt. 33 ; apertura 2} longa, 13 lata.

Hab. Sugarloat Hill and Quarry (Z'urton). Extinct (? living).

In some specimens the spire is more elevated than in others, and

occasionally the apex is scarcely raised ahove the last whorl. The
majority of the examples examined have to a great extent lost their
original colour and are now of a uniform whitish tint; but a few
from Sugarloaf Ridge, which have the appearance of live shells, look
of a pale reddish colour to the naked eye, but when viewed under a

1892.) _ LAND-SHELLS OF ST. HELENA. 261

lens it is seen that they are variegated with irregular radiating
blotches of red and white intermingled. The lines of growth are
distinct, finely hair-like, arcnate and oblique on the upper surface,
and gently undulating on the body-whorl. The umbilicus is deep
but narrow, equalling about one fifth the diameter of the base.

3. Patruxa pianz (Pfeiffer). (Plate X XI. figs. 2-2 4.)

This species does not belong to the group Hyalina (= Vitrea), as
supposed by Wollaston, but falls naturally into Patula together
with the preceding species, which it very closely resembles.

Hab. Diana’s Peak. Living (P/r.).

4, PaTULA PERSOLUTA, sp. nov. (Plate XXI. figs. 3-3 6.)

Testa minuta, late et aperte umbilicata, discoidalis, planorbi-
Sormis, pallide rufescens (?) ; anfractus 33, perconvext, sutura
profundissime discreti, subceleriter accrescentes, lineis incre-
menti obliquis striati, ultimus tubiformis, rotundatus, antice
solutus et descendens ; apertura subcircularis, margine colu-
mellari leviter planato.

Diam. maj. 33 millim., min. 23, alt. 2.

Hab. Side Path (Turton). Extinct.

This is a very remarkable little species, at once recognizable by its
Planorbiform appearance, and the detached anterior portion of the
body-whorl. The upper whorls do not rise above the last, and the
suture is remarkably deep. The umbilicus is very wide and open,
permitting the convolution of the whorls to be observed to the apex.
Both of the specimens examined exhibited traces of red towards
the apex, and there is every probability of the living shell having
exhibited more or less of that tint.

5. PATULA L&TISSIMA, sp. nov. (Plate XXI. figs. 4—4 6.)

Testa minuta, anguste wmbilicata, depresse subconoidea, alba,
maculis radiantibus rufis supra et infra picta; anfractus 53,
lente accrescentes, superne convexiusculi, sutura subprofunda
sejuncti, lineis incrementi fortibus striati, ultimus ad peri-
pheriam rotundatus, antice haud descendens ; apertura semi-
lunata, edentula ; peristoma tenue, simplex, margine columel-
lari dilatato ; umbilicus profundus, angustus, diam. totius 4
adequans.

Diam. maj. 4 millim., min. 34, alt. 23.

Hab. Sugarloaf Ridge, near the top (Turton). Extinct.

This little species is remarkable for its small deep umbilicus,
the toothless aperture, rather well-marked lines of growth, the
rounded periphery to the body-whorl, and the red colour-markings.
These consist of radiating blotches on the upper surface of the
whorls, which become rather angular and wavy on the middle and
lower part of the body-whorl.

262 MR. E. A. SMITH ON THE [Apr. 5,

PatuLa (with teeth, Endodonta).

6. PatuLa BipLtcata (Sowerby).

Hab. North of the island. Extinct.
A small species with two palatal folds. Unknown to me.

7. PATULA BILAMELLATA (Sowerby). (Plate XXI. fig. 5.)

Var. UNILAMELLATA. Aperture with the lower parietal lamella
wanting. ‘

Hab. Sugarloaf Ridge, rare (Zurton). Extinct.

This name was also applied by Pfeiffer to a small species of
‘“* Helix” in 1845, or one year after the publication of Sowerby’s
description. As it cannot be regarded as generically distinct,

although very different in form, I propose to substitute the name
Patula pagodiformis.

8. PATULA VERNONI, sp. nov. (Plate XXI. figs. 6-6 6.)

Testa anguste perforata, depresse discoidea, superne planata, ad
peripheriam acute carinata, alba, superne et infra rufo
radiata; anfractus 6, lente accrescentes, vix convexiusculi,
lineis incrementi tenuibus striati, ultimus acute carinatus,
supra et infra carinam leviter compressus, antice haud
descendens, lineis radiantibus rufis undulatis infra pictus,
radiatim tenuiter striatus ; apertura parva, subrhomboidalis,
lira parietali tenui intrante munita; peristoma simplex,
tenue, wmbilicum versus leviter incrassatum.

Diam. maj. 12 millim., min. 11, alt. 4.

Hab. Side Path (Turton). Extinet.

This species is at once recognized by its very flat spire, the com-
pressed very acute keel, the minute umbilicus, the single fine lira-
tion upon the upper part of the body-whorl, running within the
aperture, and the style of colouring. The red rays upon both the
upper and lower surfaces are more or less wavy and interrupted.
There is no other sculpture excepting the fine lines of growth which
cross the upper surface of the whorls obliquely and are a little flexuous
beneath. The body-whorl has a more distinct impression below the
keel than above it. I have much pleasure in naming this very
distinct species after my late friend T. Vernon Wollaston, whose
work ‘ Testacea Atlantica’ is one of the most accurate and complete
hitherto published upon any Molluscan fauna.

9. ParuLA PsEUSTES, sp. noy.’ (Plate XXI. figs. 7—7 6.)

Testa conoidea, pyramidalis, anguste umbilicata, albida, superne
maculis quadratis, inferne flammulis rufis picta; anfractus
63, convexi, sutura profunda discreti, radiatim tenuiter
costulati, ultimus ad peripheriam votundatus, inferne striis
tenuissimis flexuosis sculptus ; apertura lunata, obliqua, intus
denticulis inequalibus sex (duobus lamelliformibus parie-
talibus prominentibus, tribus minimis supra columellam, una

Longit. 23 millim., diam. 33 3 apertura 13 longa, 4 lata.

Hab. Fiagstaff Hill (2. W. Alewander). Extinct.

This species has the spire more elevated and conical than the
other species of Patula from the island. PP. cutteri, Pfr., may
approach it somewhat, but that species is said to have only two
parietal lamellze, and two basal denticles near the columella. The
present species has an additional basal denticle, and a prominent thin
palatal lamella, which falls as it were between the two on the inner
or parietal side of the aperture.

10. Paruta cuTrert (Pfeiffer).

Hab. Diana’s Peak. Living (Pfr.).

A small species, unknown to me, apparently similar in general
features to the preceding, but with only four teeth within the
aperture, two parietal and two basal near the columella, more
narrowly umbilcated and probably more strongly sculptured.

11. Paruta poLyopon (Sowerby). (Plate XXI. figs. 8-8 c.)

This is the most widely umbilicated of all the species of Patula from
St. Helena, and this feature alone is sufficient to distinguish it from
the rest. The whorls also, in adult shells eight to nine in number,
enlarge very slowly. The striz are fine, regular, arcuately oblique
above, and slightly wavy on the last whorl. There are three parietal
lire extending far within the aperture, of which the upper and
lower are nearly always double. The plice within the outer lip
are almost invariably (in adult shells) seven in number, subequi-
distant, but not of equal thickness, two or three towards the
columella being stouter than the rest, which are slender and extend
some distance within.

Diam. maj. 5; mill., min. 5, alt. 23.

Hab. Side Path, Sugarloaf Quarry, Sugarloaf Ridge (Turton).
Extinct.

The species to which the foregoing remarks apply is certainly the
Helix alexandri of Forbes, for in the British Museum there are
specimens of it presented by Mr. Alexander, who also furnished
Forbes with the shells he described. Moreover the description is
fairly applicable, especially that portion of it referring to the
umbilicus, which is described as “maximus.” It is much less
certain that this is the H. polyodon of Sowerby, but as Mr. Wollaston
has united these species as well as H. helenensis (Forbes), Pfeiffer, it
will probably be advisable to acquiesce in this decision. There are,
however, certain differences in the descriptions, which seem to indicate
that more than one species was described by these authors, for
instance :-—AH. polyodon is said to consist of six striated whorls, with
three parietal and five palatal lire, and a moderate-sized umbilicus,
whereas H. alexandri is described as having seven strongly striated
whorls, three parietal and eight palatal lire, and a very large
umbilicus. H. helenensis is characterized as possessing eight very

264 -MR. E. A. SMITH ON THE [Apr. 5,

narrow closely costate whorls, and only two parietal lire and the
same number within the outer lip. Pfeiffer states that H. helenensis
was described by Forbes in the Proc. Zool. Soc. for 1851, and this
statement is copied both by Reeve and Wollaston. This appears to
be an error, for after a careful search I have been unable to discover
in any publication the description by Forbes of any species of Helix
under that name.

12. ParuLa MINUTISSIMA, sp. nov. (Plate XXI. figs. 9-9 c.)

Testa conoidea-depressa, mediocriter late umbilicata, albo et rufo
maculata et variegata ; spira leviter elevata, superne obtusa ;
anfractus 7, primi duo leves, pallide rufescentes, ceteri
convexiusculi, lirulis tenuibus arcuatis obliquis, in anfr. ult.
flexuosis, ornati, ultimus ad peripheriam acute rotundatus,
vel interdum obsolete subangulatus, antice haud descendens ;
apertura oblique semilunata ; lamelle parietales tenuissime,
in cochleis adultis sex, in exemplis juvenilioribus quatuor vel
quinque; plice palatales 8-10; peristoma tenue, margine
columellari expanso.

Diam. maj. 42 millim., min. 43, alt. 24.

Hab. Sugarloaf Ridge (Turton). Extinct.

This species is smaller than P. polyodon, more narrowly umbili-
cated, has fewer whorls, coarser and more remote striz, and a
different armature within the aperture. In full-grown shells there
are aS many as six parietal lirze, as it were, in two groups of three.
They are very fine and extend a long way within. The plicee within
the outer lip vary apparently from seven or eight to ten or eleven, and
some of them are more prominent than others. The red markings
take the form of radiating blotches on the upper surface, and more
undulating or zigzag streaks beneath.

13. ParuLa LEPTALEA, sp. nov.’ (Plate XXI. figs. 10-10.)

Testa orbicularis, depressa, late wmbilicata, albida rufo variegata;
spira via elevata ; anfractus 5, primi 12 leves, cetert convex-
iusculi, tenuissime arcuatim striati, lente accrescentes, ultimus
ad peripheriam acute rotundatus, antice haud descendens ;
apertura oblique semi-lunata; lamelle parietales tres
(quarum suprema et mediana duplices sunt) tenues, longe
intrantes ; plice palatales circa sex.

Diam. maj. 33 millim., min. 3, alt. 13.

Hab. Sugarloaf Quarry (Turton). Extinct.

This species is much smaller than P. polyodon and not quite so
large as P. minutissima ; it is flatter than either, mach more finely
striated than the latter, and has a different oral armature from both.
The parietal lirae are unequal in size, that nearest the collumella
being the smallest. The two others are about equal and double,
and between occasionally a very small and slender intermediate lira
is observable.

Buuimus (Pacuyortvs).

14. Bunimus auRis-vuLPrna (Chemnitz). (Plate XXII.
figs. 11-11 d.)

Hab. All along Sugarloaf Ridge (Turton). Extinct.

With regard to this, the largest extinct snail of St. Helena,
Mr. Wollaston admits the resemblance “to a certain extent” to
certain Brazilian species, at the same time observing “that much the
same type of form exists equally in the Solomon Islands and New
Zealand.” Whilst agreeing with those remarks, I would point out
that although in the Pacific shells referred to the apertures are
somewhat similar, the general form, especially of the body-whorl, is
much more elongate. On the contrary, B. melanostoma and B.
bilabiatus from Brazil, cited by Forbes in comparison, exhibit not
only like proportions, but also similar oral characters.

Captain Turton in his notes remarks: ‘‘ The shape appears to me
to vary immensely, and therefore I have sent as many as 30 speci-
mens, so as to show all the intermediate forms. The very slender
ones are, I suppose, B. darwinianus, but I can scarcely draw any
line between them. I noticed that the different varieties of this
shell generally (always, I think) came from different parts of the
ridge; and you will observe that the more recent shells which
retain their colour do not grow to the same size as the more fossilized
ones.

I fully concur in the opinion arrived at by Captain Turton
respecting B. darwinianus (Plate XXII. fig. 11 d) being merely an
elongate form of the B. auris-vulpina.

His other observation, with regard to the smaller size of the more
recent specimens, is also very interesting. This diminution might
be accounted for by the vegetation being less luxuriant and other
conditions being less favourable to finer growth than in former
times, before the partial destruction of the primeval forests which
then clothed the island.

The freshest examples are of a light reddish colour and generally
of a somewhat darker tint towards the apex. The top of the
plications at the suture are whitish, and there is more or less of this
colour variously distributed over the surface in the form of irregular
streaks and blotches. A few subfossil snails’ eggs obtained at
Sugarloaf Ridge along with this species evidently from their size
belong to it. They are roundly ovate, being 63 millim. in length
and 6 broad. Some other much smaller eggs were also found by
Captain Turton at the same place, but in this instance it would be
mere guesswork to suggest to which species they belong.

15. ButimuLus BLOFELDI, Forbes. (Plate XXII. fig. 12.)

This species is very like the following in form, but has not the

have somewhat similar granular sculpture.

in which the plications at the suture, probably through the

‘Hab. High Peak, among native vegetation (Zurton). Living.

This perhaps is the prettiest land-shell occurring in the island,
and it is remarkable that it has escaped the notice of most of the
explorers and naturalists who have visited and collected at St.
Helena. ‘Two specimens, however, have been in the collection at the
British Museum for many years. They were received from the
Museum of Economic Geology in January 1860, but it is uncertain
by whom they were collected.

The substance of the shell is extremely thin and fragile and the
surface exhibits no other sculpture excepting lines of growth. The
colour-ornamentation is variable. In what may be regarded as the
typical form the opaque creamy longitudinal markings take the form
of broadish irregular wavy stripes, which frequently run into one
another, so that they exhibit a more or less zigzag appearance.
In other specimens these broadish stripes are replaced by very
numerous and slender lines, which are more or less wavy and some-
times considerably interrupted and broken up.

The plait or denticle upon the columella is peculiar, giving to it
a subtruncate appearance. B. neglectus, Pfr., B. costatus, Pfr.,
and some other forms of Peronzus have a somewhat similar plication
on the columella, but rather higher up. I have much pleasure in
associating this beautiful species with the name of Capt. W. H. Turton.

21. ButimuLus MELANIoIDES (Wollaston). (Plate XXII.

Hab, Diana's Peak, at an elevation of over 2000 feet (Z'urton).
Living.

This is very distinct and quite unlike any other known species.
It was located by Mr. Wollaston in the genus Sudulina on account
of the truncation or fold at the base of the columella. This feature,
although rather higher up on the columella, is also met with in
certain Bulimi from Brazil, as I have already pointed out in
connection with the preceding B. turtoni. I therefore am inclined
to assign this species rather to Bulimulus than to Subulina, as more-
over it bears very little resemblance to any species of that group.

(Turton). Extinct.

This is a very remarkable little species and quite unlike any
other from the island.

The manner in which the last whorl ascends in front upon the
penultimate recalls certain species of Tomigerus and Boysia. The
emargination at the upper part of the peristome is most remarkable.
It has the appearance of being the termination of a tube, the edge of
which is notched at one place. The shallow depression on the
lower part of the body-whorl towards the aperture and the more
distinct groove behind the peristome give the last volution a
decidedly distorted appearance. It is difficult to decide whether
this species should be classed as a Zomigerus or a Pupa. In size
it more resembles the latter genus, but in outline the former; it
has not, however, the same armature to the mouth.

Little can be suggested with regard to the origin or relationship
of the above three species, for, as is well known, Succineas all the
world over have a remarkably strong family likeness. That they
are not importations of modern times, however, is proved by the fact
that one of them occurs in a semifossil condition along with other
extinct forms of land-shells.

B. Introduced Species.

Through the kindness of Mr. E. L. Layard I have had the
opportunity of examining the types of two of Benson’s species,
namely :—Achatina veru and Bulimus compressilabris. The
former I regard as identical with the West-Indian Cecilioides
gundlachi (Pfeiffer), which is synoymous with Macrospira aperta
of Guilding from St. Vincent's, specimens of which, from Guilding’s
collection, are now in the British Museum. As it was found in
the Public Gardens at Jamestown there is every probability of its
being a comparatively recent introduction along with West-Indian
plants.

The Bulimus compressilabris aiso appears to be an introduction
from the West Indies, for it is identical with the Stenogyra ascendens
of Poey from Cuba, which I believe to be merely a slender form of
St. goodallii, Miller. The remaining introduced species have
been enumerated in the early part of this paper.

2. On an apparently undescribed Pheasant from the Province
of Zarafshan in Central Asia. By Henry Srxsoum, F.Z.S.

[Received April 5, 1892.]

Through the kindness of Mr. Tegetmeier I have been able to add
to my collection an example of a Pheasant from Central Asia which
appears to be undescribed. It is closely allied to Phasianus princi-
palis, but differs from that species in having a very conspicuous
white collar round the back of the neck but not quite meeting in
front. It further differs from that species (and resembles P. per-
sicus) in having no dark margins to the scapulars, and in having
the dark tips to the feathers of the flanks and of the sides of the
breast much narrower.

From Phasianus mongolicus, which is also a ring-necked Pheasant,
it differs in having the upper parts below the white ring brick-red,
without any trace of the green reflexions so conspicuous in that
bird. It further differs from that species (and resembles P. princi-
palis) in having the feathers of the breast broadly margined with
golden red, instead of being narrowly margined with black bronzed
with green. It is also a smaller bird, with a smaller spur.

It can scarcely be a cross between P. mongolicus and P. princi-
palis, because the white ring is an absolutely perfect one in the
most typical example of the former, whilst it is as absolutely free
from the green reflexions which characterize P. mongolicus as the
most typical example of P. principalis.

The example of this apparently new species of Pheasant was
sent to Mr. Tegetmeier by Lieutenant G. Tarnovski of Samarkand
as a specimen of the Pheasant of the Zarafshan, described by that
Russian sportsman in the ‘Field’ newspaper of the 21st of March
1891 (vol. Ixxvii. p.409), under the name of Phasianus zerafshanicus
sive Alossovskii; but in the detailed description of that species it is
stated that “on specimens shot last autumn I found on nape and sides
of neck from six to eight white small feathers invisible from without.
On the birds which are the subject of this description I have been
unable to find any of these neck-feathers.” From this statement it

1892. ] MR. R. J. L. GUPPY ON BULIMUS OBLONGUS. 271

is quite obvious that neither of the names proposed by Lieutenant
Tarnovski can be applied to the birdin question. I therefore propose
to call it Phasianus tarnovskii, after its discoverer.

It is quite possible that Phasianus zerafshanicus is distinct from
P. principalis, but its distinctness can scarcely be fully admitted
without a comparison of specimens. According to Lieutenant Tar-
novski, P. zerafshanicus has only recently made its appearance iu
the upper valley of the Zarafshan. He writes:—‘‘ Mr. Klossovski, who
had resided in Katta-Koorgan for thirteen years, informed me that
Pheasants had made their appearance in the district of Katta-Koor-
gan (where we were shooting) about 1883, and that they had
immigrated from the Bokharian dominions, probably from the Kara-
Kool lakes and reeds (the Zarafshan does not reach the Amoo-Daria,
but is lost in the sands near Kara-Kool), whence they were driven
forth by the invasion of the Kisil Koom sands, which gradually
bury the western part of Bokhara under their hills.”

Lieutenant Tarnovski further adds that ‘‘the Pheasant of the
Zarafshan has a mode of life totally differing from its other Asiatic
brethren, owing to the high state of cultivation of the Zarafshan
valley ; it breeds and nests in the reedy swamps and marshes bordering
on this stream, and takes its food from the neighbouring fields and
gardens.”

3. Note on Bulimus oblongus.
By R. J. Lecumere Guppy, C.M.Z8.

[Received March 19, 1892. |

The specimens of the anatomy of Bulimus oblongus which I ex-
hibit may have some interest for Fellows of this Society.

In my paper on the Mollusca of Trinidad published in the ‘ Annals
and Magazine of Natural History’ for January 1866 (ser. 3,
vol. xvii. p. 48), I mentioned some peculiarities of the structure of
this mollusk, which had been figured by d’Orbigny in his ‘ Voyage
dans l’Amérique Méridionale.’ The tentacular appendages of the
head call to mind the Cephalopoda, and the jaw in two horny portions
strengthens the analogy. The specimens now shown are :—(1) the
jaw preserved in glycerine, (2) the anterior portion of the animal in
spirit, (3) the dental membrane in Canada balsam, (4) the shell and
egg. These are all probably well known. 1 have had the pleasure
on more than one occasion of presenting living examples of this fine
species to the Gardens of the Society ; but, owing to its habit of
burrowing, I fear few of the visitors have had the opportunity of
seeing the creature in motion.

I take the opportunity of mentioning another fact concerning this
mollusk which may possibly be new. ‘The family Helicide, to which
Bulimus oblongus belongs, is generally considered to have the sexes
united, nevertheless requiring the congress of two individuals for
reproduction. I am not able to assert that Bulimus oblongus is.

19

272 MR. W. SCHAUS ON NEW [Apr. 5,

anatomically unisexual, yet functionally I believe it to be so.
Having observed numerous individuals and pairs, I am able to say
that the female is constantly larger than the male.

I may add a word as to the best method of killing these mollusks.
If placed in a sort of vapour-bath or in a vessel of water, and heated
very slowly and gradually, they die painlessly and in a condition
with the tissues relaxed much more suitable for the purposes of the
anatomist than if killed by immersion in hot water or in any acrid
fluid. When it is desired to preserve the shell in a perfectly clean
condition, the whole should, after the animals are dead, be boiled so
that the soft parts may readily come away from the shell.

5. Notes on the Anatomy and Osteology of the Indian
Darter (Plotus melanogaster). By Franx E. Bepparp
M.A., F.R.S.E., Prosector to the Society.

{Received March 15, 1892.]

The structure of the soft parts of both Plotus anhinga and’
P. melanogaster has been fairly completely described by my two
predecessors, Prof. Garrod’ and Mr. Forbes?. Prof. Garrod has also
given a brief account of some of the peculiarities of the third species,
P. levaillanti, in a later paper *. So far as I am aware, the only
existing account of the visceral anatomy of P. melanogaster is to be
found in Mr. Forbes’s notes upon this bird. More recently Prof.
Fiirbringer, of Jena, has contributed * to our knowledge of this
genus in his great work upon the shoulder-girdle of birds. Having
recently had the opportunity—afforded me by the death, on December
31st of the present year, of a female P. melanogaster, which arrived at
the Gardens on May 1883—of dissecting an example of that species,
I have been able to make some slight additions to what is already
on record about the bird. As will be easily imagined, I have only
to confirm the careful work of Mr. Forbes, so far as that goes ;

292 MR. F. E. BEDDARD ON THE INDIAN DARTER. [ Apr. 5

there are a few points, however, to which Mr. Forbes does not refer.
To these I have naturally paid particular attention. As regards the
musculature, Mr. Forbes only refers to some of the muscles of the
neck ; but, Fiirbringer having dissected the shoulder-muscles, I have
confined my attention to the muscles of the hind limb.

Myology.

As I have already said, the muscles of the anterior limb have
been described by Fiirbringer. In the hind limb I find no note-
worthy differences from P. anhinga. The “ muscle formula” is the
same, z7.e. AX-+.

The Semitendinosus is a comparatively slight muscle; Garrod
speaks of it in P. anhinga as being very large. It arises entirely
from the pubis, and is inserted in common with the Semimembra-
nosus.

The Semimembranosus is a very large and stout a ae at its
origin it is nearly as wide as the Biceps ; ; it is inserted by a strong
flat tendon, on to which tendon, just at its commencement, is
inserted the Semitendinosus.

There are two Adductors, of which the inner is much the largest ;
this muscle is tendinous at its origin, and it has also a tendinous in-
sertion of some length on to the underside of the femur.

The Gastrocnemius has the usual three heads of origin; the
middle head arises partly from the innermost adductor, and also by
a very slender tendon from the Semimembranosus.

The Tibialis anticus has a single and undivided tendon; in many
birds the tendon of this muscle splits into two at its insertion.

There are two Peroneals present; the Peroneus longus is, as is
invariably the case with this muscle when present, attached to the
tendon of one of the deep flexors.

As to the deep flexors, the Flexor hallucis is bound by a strong
vinculum to the Flexor profundus just at its trifurcation.

Viscera.

The accompanying drawing (fig. 1, p. 293) illustrates the very
rudimentary tongue. Mr. Forbes does not mention the tongue,
though it might be inferred from his silence on the point that “the
organ resembles that of Plotus anhinga. I have thought it worth
while to have a drawing prepared, as this structure has not been, to the
best of my knowledge, figured. Professor Garrod’s remark that “ the
tongue, as an independent organ, does not exist”’ applies to Plotus
melanogaster no less than to Plotus anhinga; there is in the former
species, as apparently in the latter, a minute process, shown in the
drawing, which is all that is left of the tongue.

I may remark that the right lobe of the liver, as in P. anhinga, is
larger than the left; and that there is a well-developed gall-bladder
(see fig. 2, p. 294), the duct of which opens as shown in the
drawing.

1892.] MR. F. E. BEDDARD ON THE INDIAN DARTER. 293

The same drawing also illustrates the arrangement of the pan-
creatic ducts, to which neither Garrod nor Forbes make any allusion
in either species. There were two minute ceca in my specimen.

The stomach agrees perfectly well with Mr. Forbes’s description of
that organ. Some of the membranes surrounding the stomach have

rather a peculiar arrangement. The liver lies near to the posterior
end of the thoracic cavity, and a considerable space is thus left
hetween its anterior border and the apex of the heart. This is a
very unusual state of affairs. As a general rule the front end of the
liver is nearly in contact with the heart. Unfortunately I have not
had the opportunity of observing how matters stand with Phalacro-
coraxz, Pelecanus, and Sula. This space which divides the liver from
the heart is of course bounded laterally by the oblique septa, and
behind by a membrane shutting off this space from the liver. It

Osteology, and Comparison with Plotus anhinga.

The osteclogy of the Darters has received attention from Brandt’,
Eyton’, Donitz , Garrod *, and Milne-Edwards §,

The only one of these authors to describe and figure the species
which is the subject of this communication is M. Milne-Edwards.
The entire skeleton, as well as the separate bones, are figured in the
magnificent work upon the Natural History of Madagascar, now in
course of publication.

Milne-Edwards, however, does not do much more than describe
the osteology of Plotus melanogaster ; there is but little in the way
of a comparison between this and other species. My object in the
present paper is to point out the principal differences between Plotus
melanogaster and P. anhinga. I must first of all refer to an inter-
esting matter concerning the skull, which has already been dealt
with by Garrod for P. anhinga.

In the figure illustrating the skull ®, Garrod has indicated a small
rod (lettered ‘“‘a”) attached to the occipital bone. Of this he
writes as follows :—“ In speaking of Phalacrocorax cristatus,
Mr. Eyton remarks, the tubercle on the upper edge of the occipital
bone has a pointed, movable, triangular process attached to it, which
I suspect has also been the case with my specimen of Plotus, but
has been lost.’”

In the Society’s female specimen there is a fibro-cartilaginous,
similarly situated process, not more than one sixth of an inch long,
which is ossified in the evidently older male. In his notes on the
anatomy of the Cormorant, Hunter tells us that “a small bone,
about an inch long, passes back from the os occipitis and gives
origin to the temporal muscle, which is very strong.” The same
bone in the Darter, although comparatively not so long, performs
the same function, the superficial temporal muscles meeting behind
the skull along the median raphe, which becomes ossified to torm the
above-mentioned bony style in the adult bird.”

This is not figured by Milne-Edwards, but I found the bone in
Plotus melanogaster attached precisely as is figured by Garrod for
P.anhinga. ‘The bone was of a triangular form, thus resembling
more closely the corresponding bone of the Cormorant. It was en-
tirely ossified. In comparing the two skulls of P. anhinga and P. me-
lanogaster, the process of the occipital bone to which the ossicle in
question is attached is seen to have a truncated form in P. meluno-
gaster, whereas in P. anhinga it has, as Garrod has correctly figured,
a more conical form, terminating in a point.

296 MR. G. B. SOWERBY ON NEW [Apr. 5,

The chief difference between the skulls of P. melanogaster and
P. anhinga, apart from the form of the occipital style, is in the
form of the palatine bones; in P. anhinga these bones are rounded
off posteriorly, the lateral margins curving inwards gradually. In
P. melanogaster, on the other hand, the thin lateral wings of the
palatines form a right angle behind ; they are cut perfectly square.

There are no other very salient points of difference in the skulls
of these two species ; in Plotus melanogaster the ridges which bound
the temporal fossze above are more pronounced than in P. anhinga ;
but possibly this is rather a difference of age than of species.
However, in Garrod’s figure of the skull of P. anhinga, which
represents that of an adult bird, and has been drawn, no doubt, from
one of the two skulls now in my custody, the same difference is
apparent ; the stronger development of the occipital style in P. mela-
nogaster perhaps needs a stronger development of these ridges, for
the two together form the line of origin of the temporal muscle.

The postorbital processes are better developed in P. anhinga than
in P. melanogaster ; this cannot be a question of age, for the skull of
P. melanogaster is that of a younger bird than that of P. anhinga.

With regard to other parts of the skeleton, the only differences
that I could detect concerned the ribs and the vertebral column.

The skeleton of Plotus anhinga has a very rudimentary rib, con-
sisting of a small bit of bone, not more than half an inch in length,
attached to about the middle of the last complete rib. This is
absent from the skeleton of P. melanogaster, and has certainly not
been lost, for that skeleton was prepared with the greatest care.

The ossification of ‘‘ Donitz’s”’ Bridge has been mentioned by
Mr. Forbes.

variety of B. succinoides (Petit). The only specimen I have seen
belongs to the National Collection at South Kensington.

BULIMULUS KOPPELI, n. sp. (Plate XXIII. figs. 9-12.)

Testa imperforata, ovato-conica, tenuis, nitens, carneo-albida vel
luteo-straminea, plerumque maculis parvis nigro-fuscis pro-
miscue conspersis picta, ad apicem carnea ; spira acute conica ;
anfractus 6, convexiusculi, longitudinaliter levissime irregu-

apertura subovalis, leviter obliqua, latiuseula, intus albida,
maculis anfractus ultimi transmeantibus; peristoma tenue,
roseo marginatum ; marginibus callo tenuissimo junctis.

Long. 25, diam. maj. 15 millim.

Hab. Bogota.

A pretty little shell, varying considerably in form and colour, but
the lip appears to be always thin and prettily edged with red. Of
the two specimens lent me for description by Mr. Da Costa, one is
nearly white, profusely sprinkled with small brown spots, while
the other is of a yellowish straw-colour (more decided yellow
towards the apex), with only a few pale spots. I have as yet only
seen very few specimens, but these exhibit considerable variations in
their proportions. One apparently abnormally inflated specimen
measures nearly 15 millimetres in width and only about 20 in
ength; while the narrowest specimen measures scarcely more than
11 millimetres in width to 21 in height.

BuLtimu.us pA-cost#, n. sp. (Plate XXIII. figs. 15, 16.)

Testa anguste sed profunde umbilicata, elongata, nitida, irregu-
lariter striata, pallide fulvo-carnea, longitudinaliter fusco
undulutim strigata, maculis parvis nigro-fuscis bifasciatim
picta ; spira convexo-conica, apice acuto; sutura leviter im-

ticalis, intus rosea, maculis perlucentibus ; peristoma simplex,
leviter reflexum.

Long. 26, diam. maj. 11 millim.

Hab. Bogota (Mus. Da Costa).

I have as yet only seen a single specimen of this species, which

may be found to vary as much as the last. It seems, however, to be
distinct from any hitherto known.

BULIMULUS GLANDINIFORMIS, n. sp. (Plate XXIII. figs. 13, 14.)

Testa anguste perforata, oblonga, tenuissima, nitida, pellucida,
stramineo-albida, longitudinaliter ruguloso-striata ; spira

Long. 21, diam. maj. 7 millim.

Hab. Bogota (Mus. Da Costa).

A transparent, fragile shell, with very much the appearance of
a Glandina.

HYALINIA GOMEZI’, n. sp. (Plate XXIII. figs. 5, 6.)

Testa perforata, depresso-rotundata, tenuis, pellucida,- nitida,
fusca, viv striatula; spira parum elevata, regularis, apice
obtusiusculo ; sutura appresso-marginata; anfractus 5, con-
vexiusculi, ultimus non descendens, votundatus, subtus convexus;
apertura transverse lunato-ovalis ; peristoma acutum, marginibus
distantibus ; columella subverticalis, dente minuto instructa.

Diam. maj. 11, min. 93, alt. 8 millim.

Hab. Bogota (Mus. Da Costa).

A small hyaline shell, the only remarkable character of which is
the presence of a minute tooth or tubercle on the columella. In
this and other respects it bears a strong resemblance to some of
the Polynesian species of Microcystis, though from its habitat it
is probably rightly placed in the genus Hyalinia.

CLAUSILIA MAGISTRA, n. sp. (Plate XXIII. figs. 1-4.)

Testa magna, anguste fusiformis, solidiuscula, sinistrorsa, nigro-
Susca; spira elongata; anfractus superstites 7, convexiusculi ;
costulis obliquis irregulariter undulatis ornati, sutura impressa
sejuncti; anfractus ultimus leviter attenuatus, ad basin ro-
tundatus, breviter solulus 3, longitudinis subequans ; apertura
late auriformis, majuscula ; peristoma continuum, expansum,
non refceum; lamella superior arcuatim subverticalis, parvi-
uscula, subcompressa; lamella inferior obliqua, latiuscula ;
clausi/ium tenue, leviter arcuatum ; plicis nullis ; lunella nulla.

Long. 38, diam. maj. 7 milli.

Hab. Bogota (Mus. Da Costa),

A fine large species, elegantly sculptured with irregularly undu-
lating oblique costule. In form it closely resembles the smaller
species, C. epistomium (Pfeiffer), which is found in the same
locality. The internal structure presents the somewhat unusual
character of being destitute of plice.

CycLoTus FILO-LIRATUS, n. sp. (Plate XXIII. figs. 17-19.)

Testa late umbilicata, depressiuscula, olivacea, saturate olivaceo~
Susco zonata, liris numerosis concentricis filiformibus insiructa ;
spira levissime elevata ; sutura profunda ; anfractus 5, convezi,

? Since this paper was read Mr. Da Costa has called my attention to the
proximity of this shell to a species named by Bland Proserpina swifti, from
which it differs in being more convex and in having a much less pronounced
tooth on the colu nella, There is no doubt that the two species belong to the
same genus; but the animals being unknown it is imposs.ble to speak with
certainty as to their position. Judging from the shells, however, I think it

- very unlikely that they belong to the Proserpinide. ‘he little Microcystis
exerescens (Mousson), from Viti Levu (Feejee Islands), has a similar dentiform
callus on the columella.—G. B. 8.

Prof. Flower, C.B., LL.D., F.R.S., President, in the Chair.

The Secretary read the following report on the additions to the
Society’s Menagerie during the month of April 1892 :—

The total number of registered additions to the Society’s Mena-
gerie during the month of April was 83, of which 31 were by
presentation, 2 by exchange, 27 by purchase, 10 by birth, and 13
were received on deposit. The total number of departures during
the same period, by death and removals, was 84.

Amongst the additions special attention may be called to :—

A Finely-marked Owl (Pseudoscops grammicus), from Jamaica,
presented by the Jamaica Institute, April 8th, being the first
living example of this Owl that has reached us.

Mr. Sclater exhibited and made remarks upon a nearly perfect
egs of one of the extinct gigantic birds of Madagascar of the genus
Aspyornis (probably 4. medius), obtained from the sands near Cape
S. Marie in the South of Madagascar, by a correspondent, resident
at Fort Dauphin, of Mr. W. Clayton Pickersgill, H.B.M. Vice-
Consul at Antananarivo, and lately brought to England by that
gentleman.

The egg measured 113 by 83 inches. Its larger circumference
was 312 inches, and its smaller 262 inches. . It was therefore not
quite so large as the specimen figured by Rowley (Orn. Mise. iii.
pl exii.), and came nearer in dimensions to the specimen ia the
British Museum (41,484) referred by Mr. Lydekker (Cat. Fossil
Birds, p. 214) to _@. medius.

The following papers were read :—

1. Field-Notes on the Antelopes of Northern Somaliland.
By H. G. C. Swayne, Capt. R.E., C.M.Z.S."

[Received April 5, 1892.]

1. Toe Oryx (Oryzx beisa).

Baet (pronounced Bey#).

The Oryx inhabits open stony ground, or barren hills, or open
grass plains.

It is very widely distributed over the Somali Country and not at
all uncommon, and it may be found in all kinds of country except
in the thick jungles with aloe undergrowth so much liked by the
Lesser Kudu, and in the cedar forests on the higher ranges.

The Oryx feeds chiefly on grass, and is often found very far from
water. It has keen sight, and protects itself more by this than by
its sense of hearing or smell.

Oryx are found in herds of moderate size, chiefly composed of
cows. The herds number from half a dozen to thirty or forty.

The only Antelopes which go in very large herds in Northern
Somaliland are the Hartebeeste and Scemmerring’s Gazelle.

Numbers of bull Oryxes are found scattered singly all about the
country, and possibly these make up in number for the prepon-
derance of cows in the herds.

Single Oryxes are almost always bulls. Often two or three cows
with growing calves will be found together, making up a small herd
of half a dozen.

It is nearly impossible to distinguish which are the bulls in a herd,
and they are so few in proportion to the cows that it is best not to
fire at a herd at all. The bull is slightly higher in the withers
than the cow, and the horns, though an inch or two shorter in the
bull, are more massive, especially about the burr at the base, and
they are more symmetrical. The cows’ horns are often bent or
of unequal length.

The Oryx is often revengeful when wounded and brought to bay.
Twice I have seen a wounded Oryx make a determined charge into
a mob of Somalis armed with spears.

The Midgans, who are the outcast race, and are armed with bows
and poisoned arrows, hunt the Oryx with packs of savage yellow
pariah dogs; the thick skin round the withers of a bull Oryx is
made by them into a white “ gdshan” or shield 18 inches in diameter.

The hunting as carried out by the Midgans in the Bulhar Plain is
as follows:—Three or four Midgans with about fifteen dogs go out
just before dawn, and walk along silently through the scattered thorn-

jungle till fresh tracks are found. These are followed till the game
is sighted. By throwing stones towards the Oryxes, whistling, and
other signs, which the dogs thoroughly understand, they are shown
the game, and settle down to their work methodically. The dogs
run mute, the men following at a crouching trot, which in a Somali
is untiring, and this lasts for a mile or two, when the dogs run into
their game and open in chorus round the herd of Oryxes as it stands
at bay. The Oryxes make repeated charges at the dogs, which are
often badly wounded. The dogs generally try to pull down a calf,
avoiding the mother’s sharp horns. Sometimes the whole herd will
charge the dogs together to rescue a calf. The Midgans come
crouching up amongst the bushes and let off a flight of poisoned
arrows into the mass of Oryx. On seeing the men, the herd breaks
up like a bursting shell. An animal wounded by one of these arrows
takes a line of its own, and is carefully followed till found dead, or
it is easily pulled down by the dogs in its weak state.

I have often joined the Bulhar Midgans in their trips. They
sleep out night after night under the trees, guarded by the half-
tamed dogs. Their camping arrangements are primitive. They
slightly roast the Oryx-meat in the fire and eat it nearly raw. If
one has no matches, one may have the pleasure of helping them light
a fire by rubbing two sticks together. It takes twenty minutes ;
special wood has te be selected. It would take Europeans a very
long time to get a light.

The pariah dogs have no affection for their masters, and growl
and snap when approached ; but, curiously, when hunting they are
very obedient and obey every sign or call.

The skin on the withers of a bull Oryx is about #inch thick. The
average length of horns in a good bull is 32 inches, in a cow 34
inches.

Young Oryxes when caught and confined in a cage will sometimes
show their stubborn, wild nature by charging the bars, head down,
and killing themselves. A case of this occurred in Berbera.

Oryxes are by no means fast Autelopes, and when wounded are
easily ridden down.

The young calves are very like those of English cattle, but smaller,
with stumpy black horns a few inches long. ‘They give out a peculiar
half-bleat, half-bellow, when attacked by dogs or wounded.

Oryxes sometimes strike sideways with their horns as we use a stick.
When angry an Oryx suddenly lowers his horns till they are nearly
parallel with the ground, and makes a dash forward with surprising
swiftness.

Lions are very fond of Oryx-meat. I have often seen Oryxes in
company with Hartebeestes and Gazelles. Once I saw a small herd
with some of the Flabby-nosed Gazelles, and amongst them were two
Ostriches.

302 CAPT. H. G. C. SWAYNE ON THE [May 3,

Kudus are found in mountainous or very broken ground where
there is plenty of bush and good grass and water.

Sometimes a solitary old bull Kudu will make his mid-day lair
close to water, in some quiet part of the hills. They are very retiring,
and live in smail families, two bulls and seven cows being the largest
number I have noticed together. They prefer the steepest mountains,
but wander about at night in search of grass in broken ground in
the neighbouring plains.

An old male with a heavy pair of horns avoids thick jungle, where
they may catch in the branches, and likes to spend the heat of the
day under the shadow of some great rock on the mountain-side,
where he can get a good view around. His eyes, nose, and ears
appear to be equally on the alert, and he is often very cunning.

Although such a heavy animal he is a good climber. He is hard
to stalk, but, once successfully approached, the steep nature of the
ground generally yields him up an easy victim to the rifle.

The alarm-note of the female Kudu is a loud startling bark, which
echoes far into the hills around, and is similar to that of the Indian
Sambar hind. The bark is accompanied by an impatient pawing of
the ground with the hoofs.

The habits of the Greater and Lesser Kudu of Somaliland exactly
correspond respectively to those of the Indian Sambar and Spotted
Deer. Great Kudus live in the mountains; Lesser Kudus live on
the bush-covered slopes at their base.

Kudus are generally timid, but care must be taken when coming
suddenly on them, as I once saw an unwounded bull Kudu make a
very determined charge from some thirty yards’ distance at a solitary
man, who had been sent to stop the mouth of a gorge. The man
jumped to one side and threw his spear, grazing the beast’s flank.
The Kudu galloped out into the plain and escaped. I had a good
view of this, and there could be no doubt as to the intention of the
beast.

The Kudu is the largest of all the Somali Antelopes, a large bull
standing about 13 hands 1 inch. A good pair of horns in Somali-
land will measure nearly 3 feet from base to tip, and 48 inches
round the spiral of each horn. The largest Somali Kudu head I
have ever seen measured 56 inches round the spiral.

The Kudu is rare except in the highest mountains. It is found
on the highest ground of Northern Somaliland, inhabiting the top
of Wagar Mountain and Golis Range, which rise respectively to six
thousand eight hundred and six thousand feet.

Kudus have Jately become very shy and scarce in these mountains.
A Kudu head is a great prize, and a good pair of horns should be
ample reward for a fortnight’s climbing in the hills.

Kudus, although active climbers, are not fast on level ground,

Gédir or Arreh-Gédir (male); Adér-yu (female) ; Adér-yu (col-
lective).

1892. ] ANTELOPES OF NORTHERN SOMALILAND. 303

This is quite the most beautiful of all the Somali Antelopes, and
the skin is more brilliantly marked and the body more graceful than
in the Great Kudu.

The Lesser Kudu is found in thick jungles of the larger kind of
thorn tree, especially where there is an undergrowth of the “‘ Hig”
or pointed aloe, which is of a light green colour and grows four
feet high. This Antelope may also be found hiding in dense
thickets of tamarisk in the river-beds. It is never found in the
open grass plains, and I have never seen one in the cedar-forests on
the top of Golis.

The favourite haunt of the Lesser Kudu used to be along the foot
of this range, but they are seldom seen there now. ‘The Lesser
Kudu likes to be near water if possible, and living, as it does, in
thick bush, its ears are wonderfully well developed. It has strong
hindquarters, and is a great jumper, the white bushy tail flashing
over the aloe clumps as it goes away in great bounds.

Lesser Kudus are very cunning and will stand quite still on the
farther side of a thicket, listening to the advancing trackers; then a
slight rustle is heard as they gallop away on the farther side.

The best way to get a specimen is to follow the new tracks of a
buck, the shooter advancing parallel with the tracker, but some 50
yards to one flank and in advance ; a snap shot may then be obtained
as the Kudu bounds out of the farther side of the thicket, first giving
the warning rustle. One may be months in the country before
getting a really good specimen.

Lesser Kudus go in small herds of about the same number as the
Great Kudus. Old bucks are nearly black, and the horns become
smooth by rubbing against trees.

The average length of a good buck Lesser Kudu’s horns is about
25 inches from base to tip. The longest I have shot or seen was
between 27 and 28 inches in a straight line. The horns are very
sharp. I have never seen a Lesser Kudu charge anybody.

4. Tae Somaui Harreseeste (Bubalis swaynei)*.

Sig.

South of the highest ranges, and at a distance of about 100 miles
from the coast, are open plains some four or five thousand feet above
sea-level, alternating with broken ground covered with thorn-jungle,
with an undergrowth of aloes growing sometimes to a height of six
feet.

This elevated country, called the “ Haud,” is waterless for three
months, from January to March ; it was crossed by Mr. James’s party
in 1884, when their camels were thirteen days without water.

Much of the Haud is bush-covered wilderness or open semi-
desert, but some of the higher plains are, at the proper season, in
early summer, covered, far as the eye can reach, with a beautiful
carpet of green grass, like English pasture-land. At this time of
the year pools of water inay be found, as the rainfall is abundant.

This kind of open grass country is called the “ Ban.” Not abush

1 Sclater, above, p. 98, pl. v.

304 CAPT. H. G. C. SWAYNE ON THE [May 3,

is to be seen, and some of these plains are thirty or forty miles each
way.

There is not always much game to be got in the Haud; but a
year ago, coming on to ground which had not yet been visited by
Europeans, I found one of these plains covered with herds of
Hartebeestes, there being perhaps a dozen herds in sight at one
time, each herd containing three or four hundred individuals.

Hundreds of bulls were scattered singly on the outskirts and in
spaces between the herds, grazing, fighting, or lying down.

The scene I describe was at a distance of over a hundred miles
from Berbera; and the game has probably been driven far beyond
that point by now.

The Hartebeeste bulls are very pugnacious, and two or three
couples may be fighting round the same herd at one time. Often
one of the bulls will be sent rolling head over heels.

The easiest way to get a specimen is to send a couple of Midgans
round above the wind to drive the Hartebeeste towards you, at the
same time lying down in the grass. A shot may be got within fifty
yards, but no one would care to shoot many Hartebeestes, as the
trophy is poor.

Often Oryxes and Scemmerring’s Gazelles are seen in company with
these great troops of Hartebeestes, but the Oryxes are much wilder.
The Hartebeestes are rather tame, and they and the Scemmerring’s
Gazelles are always the last to move away.

Hartebeestes have great curiosity, and rush round a caravan,
halting now and then within two hundred yards to gaze. This sight
is an extraordinary one, all the Antelopes having heavy and powerful
forequarters, head, and chest, of a different shade of chestnut to
the hindquarters, which are poor and fall away. In the midday
haze on the plains they look like troops of Lions.

The pace of the Hartebeeste is an ungraceful lumbering canter ;
but this is really the fleetest and most enduring of the Somali
Antelopes. The largest herd T have ever seen must have contained
a thousand individuals, packed closely together, and looking like a
regiment of cavalry, the whole plain round being dotted with single
bulls.

The coat is glossy like that of a well-groomed horse.

From their living so much in the open grass plains the Harte-
beeste must live entirely on grass, for there is nothing else to eat ;
and it must be able to exist for several days without water.

Hartebeestes are the favourite food of Lions, and once, when out
with my brother, I found a troop of three Lions sitting out on the
open plains, ten miles from the nearest bush. They had evidently
been out all night among the herds, and on their becoming gorged,
the rising sun had found them disinclined to move.

Hartebeeste horns vary greatly in shape and size. There are the
short massive horns and the long pointed ones, and all the gradations
between. Some curve forward, with the points thrown back ; others
curve outwards in the same planeas the forehead, the points turning
onward.

5. Watier’s GazeLe (Lithocranius walleri).

Gerenouk.

The Gerenouk is the commonest and most widely distributed of
the Somali Antelopes except the little Salt’s Antelope, which springs
like a hare from every thicket.

The long neck of the Gerenouk, large giraffe-like eyes, and long
mobile muzzle are peculiar, the only other Antelope at all like it
being the Dibatag (Ammodorcas clarkei).

The Gerenouk is more of a browser of bushes than a grass-feeder,
and I have twice shot them in the act of standing on the hind legs,
neck extended, and fore feet against the trunk of a tree, reaching
down the tender shoots, which could not be got in any other way.
Thus not only the appearance, but the habits of a Gerenouk are
giraffe-like.

The skull goes far back behind the ears like that of a camel.

The Gerenouk is found all over the Somali Country in small
families, never in large herds, and generally in scattered bush,
ravines, and rocky ground.

I have never seen the Gerenouk in the cedar forests which crown
Golis, nor in the treeless plains which occur in the Haud.

Gerenouk are not necessarily found near water, in fact generally
in stony ground with a sprinkling of thorn-jungle.

The gait of this Antelope is peculiar. When first seen, a buck
Gerenouk will generally be standing motionless, head well up, looking
at the intruder and trusting to its invisibility. Then the head dives
under the busbes, and the animal goes off at a long crouching trot,
stopping now and again behind some bush to gaze.

The trot is awkward-looking and very like the trot of a camel.
The Gerenouk seldom gallops, and its pace is never very fast.

In the whole shape of the head and neck and in the slender lower
jaw there is a marked resemblance between the Gerenouk and the
newly-discovered Dibatag. The texture of the coat is much alike
in both. The horns of young buck Gerenouk are almost exactly
the same shape as those of the Dibatag.

The average length of a Gerenouk’s horns is about 13 inches. I
have never seen a female with horns.

Female Gerenouks sometimes lose or desert their young ones, as I
have now and then come on quite young Gerenouk living alone in
the jungle.

6. S@MMERRING’S GAZELLE (Gazella semmerringi).
My]

Aoul.

Five years ago, when staying in quarters at Bulhar, I remember
that the Aoul could be seen from the bungalow, grazing out on the
plain. The Bulhar Maritime Plain used to be full of them, but they
have been so persecuted by sportsmen that they have retired to a
great distance, and are seldom shot near Bulhar now.

The Aoul weighs about the same as the Gerenouk, but has a
shorter neck and a clumsy-looking head. It is altogether a cuarse

306 CAPT. H. G. C. SWAYNE ON THE [May 3,

animal. It is a grass-feeder, and lives in the open plains or in
scattered bush, but never in thick jungle, and it prefers flat ground.

The white hindquarters can be seen from a great distance, making
a herd of Aoul look like a flock of sheep in the haze of the plains.

I have never seen Aoul on the Golis Range, but in the Hartebeeste
ground beyond they are common, and may often be seen in large
herds along with the herds of Hartebeestes.

The Aoul are the most stupid and easy to shoot of all the Somali
Antelopes, and their habits are identical with those of the Indian
Blackbuck ; but the Aoul is not to be compared with the Blackbuck
for beauty or grace of movement.

Aoul often make long jumps when going away, and are apparently
a near relative of the Cape Springbuck. I have never seen them
spring vertically to anything like the height to which the Indian
Blackbuck will spring. Presumably it is done to get a better view
of the plain.

Aoul are inquisitive and will follow a caravan. If fired at they
make off across the front at racing speed, drawing up in a troop now
and then to gaze.

If much meat is required, it is easy in scattered bush to run into
a large herd and shoot several. A large herd becomes confused, as
the leaders cannot be seen in bush.

The bucks with a herd will often be seen fighting or chasing each
other about at speed as Blackbuck do. Solitary bucks are sometimes
found far from any herd.

Aoul can live a long way from water. Near the coast they often
come down close to the shore, possibly to obtain salt.

A wounded Aoul buck does not hide, but will lie down in the
most open spot he can find, and will generally have a circle of jackals
waiting round him. Aoul can easily be shot at dusk, when they
are apt to blunder close to a caravan.

The horns vary in shape, generally being lyrated, sometimes
pointing forward like the Gerenouk horns. They are often mal-
formed, and seldom have much symmetry. The largest pair I have
seen measured 17 inches; the average is about 14 inches, following
the curve.

I once saw a herd of about fifteen young fawns of this Antelope
gathered together a mile away from the rest of the herd.

Tue Coast Gazewe (Gazella pelzelni).
Tue Big-NosepD GAZELLE (G. spekiz).

The ordinary Coast Gazelle almost exactly resembles the Arabian
and the Indian Gazelle (G. bennetti). The other, the Big- or
Flabby-nosed Gazelle, inhabits the elevated country, commencing
about 35 miles from the coast.

I have shot numbers of Gazelles for food at various times, and
have always noticed that the Flabby-nosed Gazelle has a much
thicker and longer coat than the Coast Gazelle. This is evidently

the result of natural selection, as the high plains of Ogo and Haud,
where it lives, are subject to sweeping cold winds, and the nights
are very cold indeed. I have noticed the Oryx in the elevated
country also have slightly thicker coats. The altitude of these
plains inhabited by the Flabby-nosed Gazelle is from three thousand
to nearly six thousand feet, but doubtless they go much lower
towards Ogaden.

The great upheaval of Golis, and its prolongations east and west,
which rise some forty miles inland and separate Guban, the low
coast country, from Ogo, the high interior country, form the natural
line of demarcation between these two Gazelles.

The short-coated, brightly-coloured Coast Gazelle is found below
in Guban, to the north of Golis. The long-coated, dull-coloured,
Flabby-nosed Gazelle is found south of Golis, in Ogo and in the
Haud.

In Ogo-Gudan, the country near Hargeisa where Guban rises
gradually into Ogo, I have found the Flabby-nosed Gazelle to
prevail. I have found that the Gazelles of the low country carried
longer horns, those of the Big-nosed Gazelle being shorter, thicker,
more curved, and better annulated.

The habits of both are alike. They go in moderate herds from
half a dozen up to about fifteen, and are fond of stony or sandy
undulating ground and ravines, thinly dotted over with mimosas.

They are fond of salt, and do not want water, and it is hard to
understand what they can pick up to eat in the wretched ground
they frequent. ‘They avoid thick bush. They have curiosity which
amounts to impudence, but are wonderfully bright and on the alert,
and are hard to shoot, knowing perfectly well the range of a rifle
and presenting a sinall target.

9. Satt’s ANTELOPE (Neotragus saltianus).

Sakdro.

The Sakaro certainly weighs less than an English hare, and is the
smallest of the Somali Antelopes. The horns are well-ringed at
the base and sharply pointed, and about 1 inch long.

There are two kinds of Sakdro, the larger and the smaller. They
are alike in every other respect, but one is half as large again as the
other. The smaller is found in Guban and Ogo. I shot the larger
in the Gadabursi country, 150 miles inland. Mr. Clarke, who weat
to Mauhan, first noticed a difference in size and pointed it out to me.
The skull is nearly twice as large in the larger kind.

The eyes of the Sakaro are larger in proportion to the head than
any other of the Antelopes here.

Sakdro live in broken ground where there is good cover of low
mimosa scrub. They are never seen in absolutely open grass plains.
They are specially partial to the aloe undergrowth found in Lesser
Kudn ground.

Sakaro go in pairs, hiding under the low bush. The female
exposes herself to view most, and is consequently most often shot.

308 ON THE ANTELOPES OF NORTHERN SOMALILAND. [May 3,

They lie very close, and when disturbed they dart off at speed
with two or three sharp whistling alarm-notes uttered in quick
succession. his often gives the alarm to larger game.

Three or four Sakdro may be seen together, seldom or never more.

Young Sakdro are soon able to take care of themselves, and only
when very young can they be run down on foot by the Somalis, who
often catch them to eat. The Somalis, who are sensible in most
ways, are peculiar in that they do not eat birds, and know little
about them, calling them contemptuously “Sbimbir,” the Arabic
for bird, but generally having no names for the different kinds.
They say birds are ‘‘ Haram,” or forbidden food.

I have seen probably eighty Sakdro in the course of aday. Their
habits are those of the hare, and they live in similar ground.

They nibble the young shoots of the mimosa. They like to be
near water, and go to drink at midday and just after nightfall. They
are especially lively in the afternoon and evening.

10. Tue Kuipsprincer (Oreotragus saltator).

Alakud.

These Antelopes live in the most rugged mountains, poising them-
selves on large boulders, and leaping from rock to rock. They are
neither shy nor hard to shoot.

Alakud go in twos and threes like Sakaro. The longest horns I
saw in Somaliland were about three inches. The females have no
horns.

11. CuarKe’s GazELLE (Ammodorcas clarkei).

Dibatag.

Clarke’s Gazelle is very local in its distribution, and is not found
nearer than Burao and the edge of the Haud. ‘They are common
in parts of the Dolbahanta country. I have never had time to
shoot when in the country they inhabit, which has only lately been
opened up. Its likeness to the Gerenouk is remarkable.

12. Berra.

My brother, while with me in the Gadabursi country last year,
saw three specimens of an Antelope which the natives called
“Beira,” but he was not fortunate in obtaining a shot. He de-
scribed it as a small reddish Antelope of the Klipspringer kind, the
same size, with little black horns, much laid back. The natives
said no Europeans had shot them.

2. On the probable Identity of certain Specimens, formerly
in the Lidth de Jeude Collection, and now in the
British Museum, with those figured by Albert Seba in
his ‘ Thesaurus’ of 1734. By Oxprietp Tuomas.

Received April 5, 1892.
I

In 1867 the British Museum purchased, through the late Mr. R.
Damon, a large quantity of zoological specimens of all sorts out of
the collection of Prof. Th. van Lidth de Jeude of Utrecht. Of the
mammals, about 280 are preserved entire in old-fashioned glass
jars with red wax tops, and 330 are skulls.

In the well-known folio work by Albert Seba, ‘ Locupletissimus
rerum naturalium Thesaurus,’ vol. i., there is a frontispiece with the
author’s portrait, and behind him are specimens in bottles so
exactly like those of the Lidth de Jeude collection as to have
attracted my attention to the circumstance ; and although it has
since proved that such bottles were used by Lidth de Jeude himself
and others, yet as the suspicion thus aroused was confirmed by my
finding some of the specimens to be similar to the animals figured
by Seba in this work, a thorough examination has been made, with
the startling and unhoped for result of showing that many of these
Lidth de Jeude specimens are actually the very individual examples
figured by Seba. Of course, one or two, or even five or six cases
of resemblance might have been put down to accidental coinci-
dences, but so large a number prove to correspond in every way
to Seba’s figures and descriptions, that I no longer have a doubt
as to their being really Seba’s specimens, carefully preserved by
their successive possessors in the original hermetically sealed jars
in which he placed them. Naturally, in the course of time, many
have been lost, others have deteriorated and been destroyed, and
others again have been alienated in ignorance of their special value
and interest. But in spite of all, enough remain to raise their
resemblance to Seba’s figures far beyond the region of accidental
coincidence, and, as each specimen identified increases the proba-
bilities for the identification of the rest, in the aggregate to amount
practically to a proof of the opinion now advocated. In fact the
whole British Museum collection from other sources could not
produce so many close resemblances to Seba’s figures as occur in
this one collection of Lidth de Jeude. It mav be noted that,
judging by the old tickets on the bottles, there appear to be two
sets of specimens in the collection—the bottles of the one labelled
with large printed numbers, and of the other with manuscript
numbers, evidently of an earlier date; all the cases of asserted
identity occur in the latter part of the collection, an evidence in
itself that these have some common bond of origin. At the same
time the importance of this piece of evidence is unfortunately much
weakened by the fact that many of the identified specimens have

we

been rebottled, so that one cannot tell with certainty * to which part
of the collection they belonged.

Owing in part probably to some of the intermediate possessors
not having been interested in anything but Mammalia, and in part
to the comparative absence of individuality in specimens of the
lower classes, scarcely any identification has been made in other
groups than the Mammalia. But as the Lidth de Jeude collection
acquired by the Museum contains specimens of all classes, both of
Vertebrates and Invertebrates, as did also the Seba cabinet, there is
little doubt that some of Seba’s specimens are contained in it, if
only they could be identified. At the same time no members of
other groups have upon them the old MS. labels to which I attach
so much importance. Moreover, the Seba collection of Reptiles
was wholly, or in part, purchased by the Emperor Peter the Great,
and taken to St. Petersburg, where many of the specimens are still
preserved”. Unfortunately they were all rebottled some years ago,
so that none are left in the original bottles ; Dr. Strauch, however, as
Iam kindly informed by Dr. Buchner, well remembers that the bottles
were exactly like those figured by Seba, and therefore like those of
the Lidth de Jeude collection. As to the labels, several sorts seem
to have been on the bottles, but none quite like those now on
our bottles.

Among the Reptiles and Fishes, in the examination of which I
have had the assistance of my colleague Mr. Boulenger, one snake
(Eunectes murinus, 66.8.14.308) and one fish (Chetostomus cir-
rhosus, 66.8.14.154) agree so well with Seba’s Vol. ii. pl. xxix.
fig. 1 and Vol. iii. pl. xxix. fig. 12 respectively, that, viewed in
conjunction with the Mammal identifications, it appears very pro-
bable that these specimens are Seba’s originals, and that they
escaped Peter the Great, and passed with the Mammals into the
hands of Prof. Lidth de Jeude.

It is an unfortunate thing that none of the many eccentricities
figured by Seba, such as the Cat with two bodies, &c., are identi-
fiable, as they would have been better evidence of identity than any
I am able to produce; but the fact is easily explicable, as the British
Museum never has purchased or collected any such specimens, and
therefore even if, as no doubt was the case, any of Seba’s monstro-
sities were included in the ‘collection trés remarquable de foetus
monstrueux”’ of the Lidth de Jeude collection, they would not

1 Tn an interesting leaflet which I owe to the kindness of Mr. R. F, Damon
of Weymouth, there is a rough classification of the Lidth de Jeude Museum,
and among the chief headings is one of “ Une série de foetus des races humaines
et des Mammiféres.” Now, on examining the Museum specimens bearing the
printed Lidth de Jeude labels, I find that without exception they are either
young specimens or else mothers containing foetuses, so that we may presume
that of the rebottled specimens those at least which are adult would not have
had the printed numbers, and would therefore in all probability have had the
old MS. labels upon them.

fire in St. Petersburg in 1747.

have been acquired by our own Museum; nor am I able to trace
where they have gone.

Before proceeding toa detailed account of my identifications, I
propose to give such scraps of historical evidence about the Seba
and Lidth de Jeude collections as I have been able to get together,
and I hope that these in course of time will be supplemented by
other similar items of information.

Firstly, from the preface to the fourth volume of the ‘ Thesaurus’
we learn that, although Seba himself died in 1736, the collection
was not dispersed until 1752, when it was sold by public auction
in Amsterdam.

It next, probably not very long afterwards’, passed into the
possession of the Stadtholder, William V. of Holland, or at least of
his guardians, he being a boy of four at the time of the sale. But
when the French occupied Holland and the Stadtholder fled in
1795, the invaders, as was their habit in regard to objects of art
and science, brought back with them to Paris certain of the spe-
cimens of the Stadtholder’s collection. Of these, or at least of the
Mammals, a list has most fortunately been preserved in the
Archives of the Paris Museum, a copy of which I owe to the
kindness of Prof. A. Milne-Edwards. This list, however (see below
p- 317), shows that no such specimens as are now attempted to be
identified went to Paris at that time. Indeed, such specimens as
these animals in spirit would not have been very attractive to the
French military and unscientific collectors, and they therefore, no
doubt, remained in Holland, but in whose hands I cannot trace.

The next reference is one which, so far as it goes, is antagonistic
to the idea of any of Seba’s spirit-specimens having been preserved
until now, and it deserves, therefore, careful consideration. In
1853 Temminck, the famous head of the Leyden Museum, made
the two following statements ? :—

“ Seba rassemblait, sans choix ni ordre systématique, toutes sortes
d’objets curieux ; parmi les mammiféres, les monstres et les foetus
étaient les plus nombreux ; toute sa collection, conservée a l’esprit
de vin dans des bocaux de verre, était, apres sa mort, en grande
partie détériorée.” And :—

“Il y a plusieurs années (cinquante ans 4 peu-prés) que je fis
Pacquisition de quelques bocaux, provenant des débris des collections
de Seba; dans ce nombre se trouvait un trés-jeune individu de
notre Spiniger ; il était totalement décoloré et & peine reconnaissable.
Ce sujet, qu’on a monté, se trouve dans nos galeries. C’est peut-
étre Yindividu type du Cervus perpusillus ou bien de Cervus per-
gracilis de Seba.”

} Perhaps Pallas visited Amsterdam in the interval, for in 1797 (Nov.
Glires, p. 314) he says of Mus longipes (Seba, vol. ii. plate xxix. fig. 2): “ vidi
quondam Amstelodamie Museo Sebz reliquum specimen in collectione DN.
Chr. Paul Meier, mercatoris.” Later on he speaks of this specimen as having
been a skin, so that it could not be one of our specimens, but might have been
one of the “Deux Gerboises de la petite espéce” that went to Paris (see

below, p. 317).
? Esq. Z. Guin. pp. 202, 203 (1853).

312 MR. 0. THOMAS ON SPECIMENS FORMERLY ___[ May 3,

Now in reference to these serious statements, it may be observed
that Seba’s great collection consisted of mammals, birds, reptiles,
scorpions, shells, echinoderms, and many other invertebrates, and
might, therefore, easily be “en grande partie détériorée,”’ especially
as regards the softer and more destructible invertebrates, and yet
leave the majority of the mammals unhurt; while, as regards the
Royal Antelope (“notre Spiniger”’), of course the accidental open-
ing or leakage of a single bottle would imply the destruction of its
contents. But except for Temminck’s bare statement, and it is by
no means certain that he really knew much about the condition of
‘toute la collection,” he only having obtained “ quelques bocaux,”
there seems to be no reason whatever that specimens preserved as
these are in hermetically sealed bottles and in good preserving
fluid should be really seriously deteriorated merely by the lapse of
time. Certainly, judging by the present condition of the Lidth de
Jeude collection, there seems to be no reason against their having
been in the bottles they now are for the past 160 years, or, if
untouched, for their remaining very much in their present con-
dition for centuries more.

Of other references to this collection, at this time or later, I
can find no trace. Probably it got into the hands of one or several
successive private and scientifically unknown collectors of curiosities
before coming into the possession of Prof. Lidth de Jeude.

Of the latter’s museum, we only know what is stated in the
preface to his sale-catalogue of 1858. In this he utters a pathetic
lament at being forced to part with his collection, the result of
half a century’s labour. This period would carry back the com-
mencement of his collecting to 1808, a date very near that when
some of the Seba specimens were certainly still in existence, as we
know from Temminck. Among the collections and even ‘* Musées
entiers ’ which he acquired during the half-century were those of
«Mr. le Baron van der Capellen, ancien Gouverneur des Indes
Orientales, Mr. van Klinkenberg, amateur zélé 4 Utrecht, Messrs.
Muller, Draak, ete.”

Of these gentlemen the first would not have been likely to possess
a general collection, of the last two I know nothing; but of the
second, the most likely sounding of all, thanks to the kind researches
of Dr. F. A. Jentink, of the Leyden Museum, we know that his
full name was Gysbert Johannes van Klinkenberg, that he set up
as an apothecary in Utrecht in 1802, that he had large Natural
History collections, and that these were sold by auction on Nov. 8,
1841. The majority of the specimens were bought by Prof. Lidth
de Jeude, but as this was done privately no sale-catalogue of them
was printed. It may be noted, however, that among the books
sold* at that sale there were two copies of Seba’s ‘ Thesaurus,’
rather a cumbrous work for an ordinary collector to have in duplicate,
if he had not had some special reason for possessing them.

1 I must sincerely thank Dr. Jentink for the care and trouble that he has
taken in helping me to trace out the history of this collection, and, among other
things, for having lent me a copy of this rare sale-catalogue, as well as a marked
copy of Lidth de Jeude’s own catalogue.

1892.] IN THE LIDTH DE JEUDE COLLECTION. 313

This being all the historical evidence that I have been able to
gather about the Seba and Lidth de Jeude collections, I need
scarcely say that I shall be most grateful to anyone who may
happen to find any pertinent references to either of them and who
would give me information thereof.

To pass now to the evidence derived from the specimens them-
selves and their agreements with the Seba’s descriptions and
figures.

In the first volume of Seba’s work about 90 Mammalia are
figured and described, and 7 in the second. Of these we must
eliminate those that were probably among the Paris set (see below),
besides a considerable number more which, owing to their size,
could not have been preserved in spirit, and such again as Seba
states were not in his own collection. This would leave some 70 or
80 for which originals may be sought. Many of these are of
animals so rare, even to the present day, that their independent
possession both by Seba and Lidth de Jeude would itself be unlikely ;
and still more unlikely that the specimens belonging to the latter
should have been able so closely to match the figures given by the
former, in age, size, and above all in sex, a point on which Seba was
fortunately very careful to give particulars.

Of the cases put forward in the following list, some few depend
of course merely on an ordinary specific resemblance, and one can
only say that there is no disqualifying point, such as wrong sex or
age; but in others, and indeed in the majority, there is a strong
imdividual resemblance between the figure and the specimen, often
confirmed by some collateral evidence extracted from Seba’s de-
scriptions. Such cases as those of the Opossums with their varying
numbers of mamme visible or in use, of the Lutra brasiliensis
with its wrinkled sides, and of the pair of Zamias with the right
sexes and number of stripes respectively, are far beyond anything
that one could possibly suppose might be due merely to accidental
coincidence.

In the table now exhibited (pp. 314-15) the first column gives the
number of the plate and figure in Seba, the second the name of the
species, and the third the British Museum register-number of the
specimen I assign to the figure. These specimens will of course
always be open to the inspection and comparison of anyone interested
in the subject.

It is unfortunate that, before the history of the collection was
suspected, many of the specimens were taken out for examination
and rebottled in modern bottles, but in all cases the fact of their
having actually come from the Lidth de Jeude collection is beyond
question. Without such taking out, however, exact specific deter-
mination is occasionally very difficult, and some animals are
therefore inserted in the table merely under their generic names, as
without very special reason it would not be right to unseal the ancient
and interesting bottles which contain them.

316. MR. 0. THOMAS ON SPECIMENS FORMERLY [May 3,

Besides these cases there are a large number of instances, such as
the young Opossum figured on Plates xxx1. & xxxvi., where
although it is impossible to fix on individual specimens as their
originals, yet practically the Lidth de Jeude collection does contain
specimens fairly corresponding with them. Further research again
will, I hope, reveal some few more cases of close identities, as I
cannot feel that I have by any means exhausted the possibilities in
this direction.

It would appear certain, then, that so large a number of resem-
blances as the above cannot be merely an accident, especially when
some of the more remarkable cases are taken into account, and I
can, therefore, only reiterate my belief that these are the actual
specimens from which Seba took his figures.

But besides its extreme interest, this fact has a special scientific
importance, for in many cases systematic names have been given,
primarily or solely, to Seba’s figures, and therefore, where the
originals of these figures can be identified, the specimens are clearly
the types of the species.

The tracing of such names, however, can only be properly done
in connection with the systematic working out of the different
groups, and the following cases are therefore only those of which
I now have clear evidence and are perhaps but a small proportion
of those which really exist.

Names of Species founded on Seba’s figures, for which typical
specimens have been identified.

1 Linneeus’s name “ asiatica” is equally founded on this specimen, but, being
erroneous, is not admissible.

? This will affect the name of the species, which will have to stand as
Pteropus vampyrus, L. Even if the identification of the specimen is wrong,
however, Seba’s LVII. 1 & 2 clearly represent what has been known as Pé.
edulis, Geoff., so that the change would have to take place in any case.

° The male specimen accidentally omitted from the list in the Catalogue.

Finally, in order to focus as far as possible all the existing infor-
mation about the Seba cabinet, I have thought it well to reproduce
just as it stands the list, obligingly hunted out for me by Prof.
Milne-Edwards, of the specimens taken to Paris. The numbers
placed in brackets are those of the Seba plates and figures which
may be those of the specimens mentioned. How many of these
interesting specimens still remain in the Paris Museum after the
lapse of nearly a century, I will leave my confréres of that great
institution to determine ; but I am afraid there cannot be many, as
the specimens seem to have been for the most part perishable skins
or stuffed specimens.

Adding to this list the Royal Antelope (Nunotragus pygmaeus),
said by Temminck to he possibly the original of xx111.2, and the
specimens asserted by Sundevall to be perhaps those of xu1u1.

now in the British Museum, for a very large proportion of Albert
Seba’s historical collection of Mammalia.

4. On some Specimens of Frogs in the Indian Museum,
Calcutta, with Descriptions of several new Species. By
W. L. Sctarer, M.A., F.Z.S.

[Received May 2, 1892.]
(Plate XXIV.)

Before leaving Calcutta at the end of last year I had been engaged
in examining the collection of Batrachians contained in the Indian
Museum.

The collection comprises examples of 180 species, of which 103

42 MR. W. L. SCLATER ON SPECIMENS OF [May 3,

are Indian and Malayan, and 77 are exotic. The number of speci-
mens is 2045, of which again the bulk (1698) are Indian, and 347
are exotic.

The number of species of Batrachians described in Mr. Boulenger’s
recent book (‘Reptilia and Batrachia of British India’) is 130, of
which 5 are referred to the Batrachia Apoda, and | to the Batrachia
Caudata; leaving 124 belonging to the Batrachia Salientia ; so that
it will be seen that a considerable number of the Indian species
are still unrepresented in the Indian Museum. A list of these de-
siderata is given below.

The collection contains a considerable number of types described
by Stoliczka, Anderson, Blyth, and others. Of these also I have
thought it worth while to give a list.

A complete list of the specimens of Batrachians in the Indian
Museum which I have drawn up will shortly be printed and
published by order of the Trustees. In the meanwhile I offer
to the Society these notes upon some of the more noteworthy
specimens.

My best thanks are due to Mr. G. A. Boulenger of the British
Museum, who has most kindly assisted me both in naming obscure
specimens and in drawing up the descriptions of the new species.
The types of the latter will all be returned to the Indian Museum.

1. Rana vicina. (Plate XXIV. figs. 1, 1 a.)

This Frog was described by Stoliczka (Proc. As. Soc. Beng. 1872,
p- 130), and was with doubt referred by Boulenger (Ind. Rept.
p- 445) to Rana liebigii.

An examination of the type at once shows that this Frog has
nothing to do with R. liebigit, but that it must remain separate as
a distinct species.

The following is a redescription of the type :—Vomerine teeth, two
small oblique groups commencing at the middle of the choane and
extending somewhat behind them; no tooth-like prominence on
the lower jaw in the two specimens available for examination ; head
moderate; snout somewhat oval; canthus rostralis slightly marked ;
nostril halfway between the eye and the tip of the snout; upper
eyelid two-thirds the width of the interorbital space ; no trace of
the tympanum ; fingers blunt, first slightly shorter than the second ;
toes webbed to the extreme tips ; subarticular tubercles well marked
and a long narrow not very large inner metatarsal tubercle, about
half the length of the inner toes; no outer metatarsal tubercle ;
tibio-tarsal articulation reaches to in front of the eye; skin of back
and belly smooth, a few tubercles on the flanks. Brown above;
hind limbs mottled darker; upper lip dark brown and a dark
irregular line from the nostril to the eye and from the eye to the
commencement of the arm; below lighter brown, rather darker
under the chin.

This Frog seems on the whole most nearly allied to R. corrugata,
Peters, from Ceylon, from which, however, it differs in the absence
of the tooth-like prominences of the lower jaw, the much broader

1892. ] FROGS IN THE INDIAN MUSEUM. 343

upper eyelid, and the longer legs; its aspect, too, is different, owing
to the eyes being normally placed, instead of being prominently
turned upwards.

Besides the original type, which was procured by Stoliczka at
Murree, in the Himalayas, at an elevation of 6000 ft., there is a
second specimen in the Indian Museum presented by Lieut. Newn-
ham, and procured near Simla. The figure is taken from the
former specimen, the type of the species.

2. Rana tresrert, Giinth.; Boulenger, Ind. Rept. p. 445.

This species has not been known to occur west of Nepal, whence
came the type. There is, however, an example in the Indian Museum
from Tavoy in Southern Burma, which extends its geographical
range considerably beyond what has hitherto been known.

3. Rana rex, Boulenger, Ann. Mus. Genova, (2) v. 1887, p. 418,
pl. iii. ; id. Ind. Rept. p. 446.

Among the Frogs of the Indian Museum I have found a second
specimen of this species. This was procured at Hotha in Yunan
by Dr. J. Anderson, but was apparently not described by him in
his ‘ Scientific Results of the Yunan Expedition.’

4. RANA ASSAMENSIS, sp. n. (Plate XXIV. figs. 2, 2 a.)

Vomerine teeth in two strong, slightly oblique, series between the
choanz, commencing at the inner anterior corner; lower jaw not
provided with bony prominences in the single specimen available
for examination; head moderate, somewhat blunt and narrow;
nostril equidistant from the eye and the tip of the snout; inter-
orbital space very slightly broader than the upper eyelid ; canthus
rostralis marked, loreal region concave ; tympanum very distinct,
somewhat oval, barely half the diameter of the eye; fingers rather
slender, the first and second nearly equal in length ; toes webbed to
the tips, with the tips slightly swollen; subarticular tubercles well
developed, inner metatarsal tubercle elongate, and about two-thirds
the length of the inner toe; no outer tubercle; a tarsal fold present ;
the tibio-tarsal articulation reaches well beyond the tip of the snout;
skin smooth above and below.

Colour in spirit : above brown, the canthus rostralis and a patch
behind the eye embracing the tympanum darker ; a dark line with
white edges running from the eye on either side backwards to the
sacrum, corresponding in position to the glandular lateral folds, but
no trace of a glandular lateral thickening can be distinguished ; legs
transversely barred ; below lighter, with darker spots on the lower
jaw.

Length from snout to vent 70 millim.

Allied to Rana andersonii, but the vomerine teeth commence at the
anterior inner edge of the choanz, and the legs are considerably
longer, the tibio-tarsal articulation reaching some way beyond the
tip of the snout.

344 MR. W. L, SCLATER ON SPECIMENS OF [May 3,

Described from a single specimen in the Indian Museum, procured
by the late Dr. Jerdon in the Khasia hills in Assam.

5. RANA HASCHEANA, Stoliczka, Jourr. As. Soc. Beng. xxxix.
1870, p. 147, pl. ix. fig. 3.

An examination of the type of this species preserved in the
Indian Museum shows that it is nearly allied to R. dorie, Boulg.
The general shape is the same, the legs are about the same length,
and the vomerine teeth commence on a level with the hinder edge
of the choanz. The only real distinction is in the toes, which in
R. dorie are webbed to the tips, but in R. hascheana for only about
one-third of their length.

6. RANA LimBorGI, sp. n. (Plate XXIV. figs, 3, 3a.)

Vomerine teeth in two oblique groups, commencing on a level
with the choanz and extending well behind them; slight traces of
the bony prominences of the lower jaw; head moderate ; snout
short, hardly longer than the diameter of the orbit; canthus ros-
tralis very rounded, hardly marked; loreal region almost flat ;
nostril about equidistant from the tip of the snout and the front of
the orbit ; interorbital space as broad as the upper eyelid; tym-
panum distinct, nearly as large as the eye, with a very thick fold
above it; first finger extending slightly beyond the second; toes
moderate, slender, only about a third webbed, the web extending
only about halfway up the first joint of the digits; a slight cuta-
neous ridge along the fifth toe; tips of fingers and toes but very
slightly swollen; subarticular tubercles fairly well developed; no
outer metatarsal tubercle ; a large, compressed, fairly sharp-ridged
inner metatarsal tubercle, very nearly as large as the inner toe;
traces of a tarsal fold present; the tibio-tarsal articulation reaches
the nostril; skin above granular, with slight traces of a granular
lateral fold running back on either side from behind the eye and a
transverse fold between its posterior borders ; below smooth.

Colour above a faded olive-brown, below lighter.

Length from snout to vent 24 millim.

This species is somewhat intermediate between RK. dorie and
R. rufescens; from tbe former it differs in having only very slightly
webbed toes and a compressed flattened metatarsal tubercle, and
from the latter in its vomerine teeth, which commence only on a
level with the posterior corners of the choanz, and from both in
the presence of its rudimentary glandular lateral fold.

This description is taken from a single specimen procured in
Tenasserim by Mr. Limborg, to whom I have dedicated the species.

7. Rana tier1nA, Daud.; Boulenger, Ind. Rept. p. 449.

A small Frog from Penang, described by Stoliczka (Journ. As. Soe.
Beng. xxxix. 1870, p. 142) as R. gracilis, var. pulla, seems to be
merely the young of RR. tigrina; that the type has only just lost
the larval tail is shown by the persistence of the tail-scar.

1892. ] FROGS IN THE INDIAN MUSEUM. 345

8. RANA TENASSERIMENSIS, sp. n. (Plate XXIV. figs. 4, 4 a.)

Vomerine teeth not well developed, in one specimen absent alto-
gether, in another in two oval groups between the choanz ; no
papillee on the tongue; head short and rounded, with indistinct
canthus rostralis and slightly concave loreal region; nostril a good
deal nearer the tip of the snout than the eye; interorbital space
somewhat wider than the upper eyelid; tympanum distinct, about
two-thirds the size of the eye; fingers and toes moderate, the tips
dilated into quite large disks, about one-third the size of the tym-
panum ; first finger much shorter than the second ; toes rather less
than one-third webbed, webs extending to about a level with the first
joint of the phalanges ; subarticular tubercles moderate ; a small oval,
flat, inner metatarsal tubercle; no tarsal fold; a fringe along the
fifth toe ; tibio-tarsal articulation reaching to a level with the front of
the eye; skin of the back wrinkled into short longitudinal glandular
folds; a fold from the eye to the shoulder above the tympanum.

Above brown, with darker spots and scattered white blotches ;
limbs both fore and hind cross-barred; beneath lighter brown,
minutely speckled with darker.

Length, snout to vent 22 millim.

This Frog seems to be most nearly allied to R. leptodactyla, from
which, however, it differs in wanting the free pointed papille of the
tongue and having shorter legs. It is altogether a very distinct
species.

It is perhaps somewhat near to R. hascheana, Stol. (above, p. 344),
from which, however, it differs in its rough granular skin, its indis-
tinct vomerine teeth, and lastly, and chiefly, in its very much larger
fingers and toe-disks.

There are five examples of this species in the Indian Museum, all
collected by Mr. Limborg in Tenasserim.

9. Rana Graciuis, Gravenh.; Boulenger, Ind. Rept. p. 456.

The type of Lymnodytes macularius, Blyth, which species has
been identified by Boulenger with R. gracilis, Gravenh., agrees very
well with the description given of this Frog by Boulenger (Joc. cit.),
except for the fact that the skin above is very distinctly granulate,
as in R. malabarica.

10. RaNA NIGROVITTATA (=TYTLERI) and R. ERYTHR#A.

The distinction drawn by Boulenger, namely, the presence of an
outer metatarsal tubercle in 2. ¢yéleri and its absence in R. erythrea,
does not seem to be very constant; in fact the only difference of
specific value between the two forms seems to be that in R. erythrea
the dorsal glandular lateral fold is very much thicker and more
prominent than in R. tyéleri.

The type of Hylorana tytleri of Theobald, which is in the Indian
Museum, has a very thick glandular lateral fold, and must therefore
be referred to R. erythrea; the other species, the form described
by Boulenger under the name R. ¢ytleri, will therefore require

346 MR. W. L. SCLATER ON SPECIMENS OF [May 3,

another name. Hylorana leptoglossa, Cope, the second name in
Boulenger’s list of synonyms, also refers to a species with a thick
and heavy glandular lateral fold, and must therefore be referred to
R. erythrea too; of Hylorana pipiens, Jerdon, the specific name
‘* pipiens”? is already engaged; Hylorana granulosa, Anderson,
refers to a different species altogether (see below).

The type of Limnodytes nigrovittatus (Blyth, Journ. As. Soc.
Beng. xxiv. 1855, p. 718) is still in the Indian Museum, and an
examination of it shows that it must clearly be referred to Bou-
lenger’s Rana tytleri. |The species will therefore stand under the
name Rana nigrovittata (Blyth).

There are examples of this species in the Museum from all parts
of Assam, Cachar, Pegu, and Tenasserim, and of R. erythrea from
Lower Bengal (Calcutta and Dacca), Assam, and Burma.

11. Rana GRANULOSA, Anderson, Journ. As. Soc. Beng. xl. 1871,
p- 23.

This species has been provisionally identified by Boulenger (Ind,
Rept. p. 458) with Rana nigrovittata (= ana tytleri, Boul.), but it
differs markedly from it in many ways. The vomerine teeth are
longer, and usually reach to well behind the choane; the first
finger éxtends well beyond the second; the toes are two-thirds
webbed, the web being deeply incised and barely reaching to the tips
of the third and fifth digits; the subarticular and the inner and outer
metatarsal tubercles are all very strongly developed; the skin of the
back is markedly granulate, with broad prominent glandular lateral
folds; there is a second glandular fold along the upper lips from
below the eye to the shoulder, ending in a large rounded granule ;
the colour is reddish brown above, irregularly spotted, darker below,
speckled throughout.

12. RHAcoPHORUS LATERALIS, Boulenger, Aun. Mag. N. H. (5)
xii. 1883, p. 162; id. Ind. Rept. p. 473.

There is a second specimen of this hitherto unique species in the
Indian Museum ; it was obtained by Mr. W. M. Daly at Koppa in
Mysore, and by him presented to the Museum.

13. RuacorpHorus CAvirostRis (Giinth.); Boulenger, Ind. Rept.
p- 481.

There is a Frog in the Indian Museum resembling the type of
R. cavirostris in every respect, except that the hind limbs are a little
longer, since the tibio-tarsal articulation reaches the tip of the snout,
whereas in the typical form the tibio-tarsal articulation reaches only
to between the eye and the snout.

The Indian Museum specimen was procured by Limborg in
Tenasserim, and, if correctly referred to R. cavirostris, considerably
extends the distribution of this species, which has hitherto been
known only from Ceylon.

14. [xaLus CINERASCENS, Stoliczka, Proc. As. Soc. Beng. 1870,
p- 275. :

This species has been referred by Boulenger (Ind. Rept. p. 510)
to Leptobrachium monticola; but an examination of the type shows
that it is a true /valus, and that it is most nearly allied to Ivalus
hypomelas, Giinth., from which it differs in its shorter snout and its
shorter legs, the tibio-tarsal articulation only reaching as far as the
eye; the legs also are cross-banded.

15. Ixatus GLanpuLosus (Jerdon); Boulenger, Ind. Rept.
p- 488.

Ixalus punctatus (Anderson, Journ. As. Soc. Beng. xl. 1871,
p- 27), identified with doubt by Boulenger with Ivalus leucorhinus,
is really, as shown by comparison of the type in the Indian Museum,
identical with Ivalus glandulosus.

16. Ixatus asper, Boulenger, P. Z. 8. 1886, p.415.

The Indian Museum possesses an example of this species procured
by one of the Museum Collectors in the Burma-Siam hills. It had
previously been got only by Mr. Wray in Perak, so that it is an
addition to the Indian fauna. The Indian Museum specimen agrees
in every way with the type, with which it has been compared.

17. MicroHyLA acHATINA (Boie); Boulenger, Cat. Batr. Sal.
p- 166.

The Indian Museum possesses an example of this little Frog from
Ahsoon in Tenasserim. As this species has been hitherto recorded
only from Java and the Moluccas, it is an addition to the fauna of
British India.

18. Buro sromaticus, Liitken ; Boulenger, Ann. Mag. N. H.
(6) vii. 1891, p. 463.

The Indian Museum possesses examples of this Toad from Calcutta
and Burma, which agree very well with the type in the British
Museum. This species is probably not uncommon in Lower Bengal,
but has hitherto been confounded with Bufo andersonii.

19. Buro parieraLis, Boulenger, Cat. Batr. Sal. p. 312.

A Frog in the Indian Museum from Hongkong, received from the
Hongkong Museum in exchange, seems reterable to this species,
which has hitherto been got only in Malabar. It is just possible
that a mistake has been made in the labelling ; but if this is not the
case, the distributional area of this species is considerably extended.

20. LEproBRACHIUM CARINENSE, Goulenger, Ann. Mus. Genova,
(2) vii. 1889, p. 748; id. Rept. Ind. p. 511.

An example of this species, procured very many years ago by
Major Berdmore in Burma, and named Megalophrys montana by
Blyth, is very interesting, in that it possesses vomerine teeth in
two very nearly parallel lmes between the choane, and separated

from one another by a considerable interval. In the types of L. cari-
nense described by Boulenger the vomerine teeth are entirely absent,
but they are to be found in the nearly allied Z. fee. This shows the
uselessness of vomerine teeth alone as a generic or even as a specific
distinction. Further, in this specimen the interorbital space is very
wide, three times as broad as the upper eyelid ; and there are two
palpebral appendages on either side to the eyelids.

5. On some Aquatic Oligochetous Worms. By
Frank E. Bepparp, M.A., F.R.S.E., &c.

[Received May 3, 1892.]

In the following remarks I propose to bring together a few notes
upon certain aquatic Oligochzeta which I have had the opportunity
of examining during the last year.

i. On a Species of Dero.

, Our principal knowledge of this genus is due to Perrier‘ and to
Stole*. A recent paper by Bousfield* is mainly devoted to discrim-
inating the species, though it contains a brief résumé of the structure
of the genus Dero.

I have recently been studying a species which I cannot identify
certainly with any known form; my failure to identify it is largely
due to the fact that the differences in the vascular system of dif-
ferent species have not been worked out. Only in two, viz. D. per-
rieri and D. digitata, has the vascular system been described; and
as these two show dissimilarities, it is at least possible that the
remaining species do also. In any case, the Dero at which I have .
worked differs from both these species. According to Perrier,
Dero perrieri has three pairs of contractile perivisceral trunks in
segments vi., vii., and viii. Behind the viiith segment the dorsal
vessel is not directly ,united with the ventral.

Of Dero digitata, Stole says, in the French abstract with which
his paper concludes, “ Il y a toujours deux vaisseaux latéraux dans
chaque anneau suivant jusqu’au treiziéme anneau (si l’animal est
complétement développé). Dans les anneaux postérieurs les anses
vasculaires remplacent les vaisseaux latéraux.” I cannot, I confess,
quite understand the distinction which is here drawn between the
two kinds of perivisceral trunks; unless, indeed, it is meant that
the anterior series are contractile. As Dr. Stole’s paper is in Bohe-
mian I am unable to say whether this is stated.

The Dero examined by myself is a small species about a quarter
of an inch in length. Like other Deros it fabricates a tube, which
was always in the interior of half-decayed stems of plants; the
stems had to be carefully torn up with needles to liberate the worms’.
The number of segments varied from 16 to 52. The characters of
the setze call for no comment ; the branchial processes most resemble
those of D. limosa.

The vascular system is remarkable for the fact that there are six
pairs of contractile lateral vessels in segments vi.—xi. Those of

1 “ Histoire naturelle du Dero obtusa,’ Arch. Zool. Exp. t. i. p.65, Bousfield
points out that the species investigated by Perrier is not Dero obtusa, but a new
form for which the name D. perrieri is suggested.

segments viii. and ix. are wider than the others; the pair of seg-
ment vii. are hardly of less calibre; the other contractile lateral
vessels are decidedly thinner. The non-contractile perivisceral vessels
were obvious in the posterior segments of the body. The first pair
of ‘‘ hearts ” each give off a slender branch, which runs forward in
the direction of the pharynx. I did not find a corresponding
branch to arise from the following “ hearts.”

The “stomach” is in segments x. and xi.; the wider part of the
intestine commences in segment xiv., but there was some variability
in this point. In some individuals I could recognize no narrow
cesophagus following the “stomach.” The lattice-work of blood-
vessels upon the alimentary tract was in many specimens very clear.
On the “stomach ” this was particularly so, and I found a longi-
tudinal trunk, such as Stole has figured in Nats, on one side; the
nephridia vary much as to the segment where they begin. Perrier
mentions the sixth segment, so too does Bousfield. In the first
individual which I examined they were apparent from the viiith
segment ; in another they did not begin until the xiith segment ;
in a third the ninth segment contained the first pair.

ii. Note upon Pristina longiseta.

In a valuable paper upon the Naidomorpha, published in a recent
number of ‘ The Quarterly Journal of Microscopical Science,’ Prof.
A.G. Bourne ' remarks of Pristina longiseta, “This species has been
recently re-described by Vejdovsky. I have not seen it, nor has it,
so far as I know, ever been recorded from England.”

Having lately had the opportunity of examining a specimen, I
offer the following remarks upon it. Firstly, its occurrence in
England is of interest. There is no doubt, however, that the small
number of aquatic Oligocheta hitherto recorded from Great Britain
is simply due to the fact that they have not been looked for. The
worm has been figured by Leidy*, d’?Udekem’*, and Vejdovsky *.
Neither d’Udekem nor Tauber® appear to have known of Leidy’s
paper. Vejdovsky does not refer to it in the list of synonyms of
Pristina longiseta, but does mention both the paper and the species,
without comment, under the description of the family Naidomorpha ;
in the table of known species of Naids and their distribution
Vejdovsky does not cite N. America as a locality for Pristina longi-
seta. The double omission therefore leads me to the opinion that
Vejdovsky was not certain as to the identity of the species termed
by himself and Leidy Pristina longiseta. Vaillant, moreover, con-
siders that the identity of the two is not fully established ; the only
difference, however, to which he calls attention is a difference of

size. Leidy’s specimen measured 1 line (=2 mm.), Vejdovsky’s
8mm. My own specimen being somewhat intermediate in size
perhaps removes this difference. But a more important difference
remains, which is not alluded to by Vaillant *. In Vejdovsky’s figure *
of Pristina longiseta no sharp line of demarcation is indicated be-
tween the prostomium and the first segment of the body, and in the
description cf the species’ he remarks :—‘‘ Der Kopflappen verjiingt
sich allmialig zu einem konischen fadenforinigen Riissel.”” On the
other hand, Leidy’s figure indicates a sharp demarcation ; the “ pro-
boscis ” commences quite abruptly. So too, though perhaps to a less
extent, does d’Udekem’s figure. The specimen examined by myself
resembles Leidy’s figure much more than that of Vejdovsky. The
location of the ‘‘ stomach ”’ by Leidy in the viith segment may be
perhaps an error. I found, as Leidy has figured, tactile hairs to be
very abundant upon the anal segment as well as upon the prosto-
mium and first segment of the body. It appeared to me that the
prostomiym was deeply grooved upon the under surface, the groove
becoming continuous behind with the mouth. In view of the slight
difference recorded above, I am not assured that Leidy’s and Vej-
dovsky’s worms belong to the same species; the specimen seen by
myself evidently is identical with the worms described by Leidy and
d’Udekem. Prof. Bourne’s paper, to which I have referred, seems
to me to destroy the generic distinctions between Pristina and
Naidium. Previous to the appearance of that paper they could be
distinguished as follows :—

Pristina :
1. Dorsal setze of segment iii. long.
2. Prostomium elongate.
3. Shorter dorsal setze not bifid.
Naidium :
1. These setz not longer than others.
2. Prostomium short with lateral processes.
3. These setz bifid.

But in Bourne’s Pristina equiseta the first character is that of
Naidium, and in P. breviseta there are bifid sete in the dorsal
bundles much like those of Naidium. The only differential character
which remains is therefore the prostomial tentacle; but in Naidium
luteum the prostomium is said by Vejdovsky to be “lang ausge-
zogen,” and in P. longiseta, as figured by the same author, the pro-
stomial tentacle is not so distinct as in other species. I do not
think, therefore, that these two genera can be any longer distin-
guished.
ili, On Aolosoma niveum.

The only description of this species was published nearly thirty
years ago by Leydig*; it has since been met with by Timm’, who

25*

352 MR. F, E. BEDDARD ON [May 3,

called it—evidently by a slip of the pen—‘‘ Holosoma lacteum.”
I have lately examined a single specimen of an olosoma which I
refer to this species. Unfortunately I am not able to fix its locality
with accuracy, as I found it in a bottle containing water and weeds
from various sources.

Leydig himself was of opinion that the species might turn out on
further study to be an immature stage of 4. hemprichii, or of
some species with coloured oil-drops in the integument; but he
quoted, as against this possibility, Ehrenberg’s observation that the
red colour is visible in embryos still within the egg, and was there-
fore, on the whole, inclined to regard the worm as an adult form of
a species with a colourless integument.

I have, however, recently pointed out that ' the supposed cocoons
are in all probability merely cysts into which the worms can tem-
porarily withdraw themselves ; so that Leydig’s opinion as to the
possibility of his Holosoma niveum being an immature form is not
necessarily rendered untenable by Ehrenberg’s observations.

Vejdovsky * in describing briefly the characters of his new species,
AZolosoma variegatum, remarked that it was ‘‘ hochst wahrscheinlich
von Leydig beobachtet und als olosoma niveum beschrieben.”
In a fuller account*® of 4. variegatum Vejdovsky establishes its
distinctness from olosoma niveum ; it agrees, however, with that
form in possessing some colourless oil-globules in the epidermis, the
rest being green. In Molosoma niveum all the integumental oil-
globules are colourless.

The most recent remarks upon Leydig’s 4olosoma niveum known
to me are to be found in Vaillant’s account of the Oligocheeta in the
‘Suites 4 Buffon.’ In that work Vaillant considers it to be not yet
established that the supposed species is not the young form of some
other olosoma. I am therefore particularly glad to be able,
I think, to definitely settle this question.

I had on the same slide and under examination at the same time
no less than three species of 4%0/osoma—an experience which is not,
I imagine, very common. ‘These species were, 4?. quaternarium,
4G. niveum, and a species of whose identity I am not quite certain ;
it was as large as my olosoma headleyi*, but may be Holosoma
variegatum; I lost sight of it before I completed the examination.
The worm which I believe to be Holosoma niveum is at any rate
a perfectly distinct species from any knowa to me. It comes nearest
to Holosoma niveum as described by Leydig. Nevertheless, it does
not altogether agree with his description. It may therefore con-
ceivably be anew form. It was fully as large as 4. quaternarium,
and there are other reasons for believing that it cannot be the young
of that, or indeed of any other known species.

1892.] AQUATIC OLIGOCHZTOUS WORMS. 353

The worm consisted of eight segments, after which came a bud
that had been in part detached ; but I succeeded in finding the rest
of it upon the slide ; the number of segments, therefore, is approxi-
mately the same as Leydig gives for olosoma niveum, and the
same number also that Vejdovsky gives for Holosoma variegatum.
The prostomium, however, was large, squarish in front, and dis-
tinctly wider than the rest of the body. Leydig figures a very
inconspicuous prostomium, which, in front at least, is actually nar-
rower than the succeeding segments. With regard to the colourless
oil-drops in the integument, I could see no structures that were at
all obvious. There was no appearance such as is represented in
Leydig’s figures. Nor were there any clearly defined droplets such
as Vejdovsky figures in his olosoma variegatum. I should be
inclined to say that there were no oil-drops present at all. The
epidermis was much more like that of a Naid or a Chetogaster than
an 4olosoma ; and even when the worm was treated with potash,
which produces such recognizable effects’ upon the oil-globules of
other species, no alterations were observable, except that the worm
was stained a faint yellowish. And yet there is no doubt whatever
that I am right in referring the Annelid to the genus Zolosoma.
Tn all other particulars it agreed with that genus. The prostomium
was ciliated on the under surface, and the lateral ciliated pits are
present. The mouth appeared to he situated rather further back
than it has been usually figured for this genus; the constriction
which marks eff the prostomium posteriorly was situated some little
way in front of the actual mouth-opening.

The most important difference, however, from Leydig’s description
concerns the setee. In all the species of Holosoma at present known,
with the exception of Vejdovsky’s olosoma tenebrarum and (if it
be really distinet from this) Holosoma leidyi*, there are only
capillary setze present in both dorsal and ventral bundles. In the
two species above mentioned cleft sigmoid setz are also to be found ®.
In the specimen of olosoma niveum described here I have also
found these sigmoid setz, and it is principally the fact of the occur-
rence of these setze which leads me to doubt the identity of this
worm with Leydig’s dolosoma niveum. Had they been present
Leydig would hardly have overlooked them. The existence of these
sigmoid sete also, I may point out, precludes the possibility of this
worm being the young of Molosoma quaternarium, and 1 do not
think that it has anything to do with olosoma tenebrarum.

In the first seta-bearing segment there were not any sigmoid
sete, but four capilliform setz in each of the dorsal, and three in

3 T am not quite certain that the species described by me as Molosoma tene-
brarum (P. Z. 8, 1889, p. 51) is really identical with Vejdovsky’s species; I
could not detect the cleft at the end of the sete, and the colour of the oil-drops
appears to be rather different,

354 MR. F. £. BEDDARD ON [May 3,

each of the ventral bundles. The number of sete per bundle dimin-
ishes in the posterior segments, and they become mingled with
sigmoid sete. In the seventh segment both sete in one of the
ventral bundles were sigmoid, as was one of the two sete of the
dorsal bundle. The sigmoid setz occur, therefore, in both dorsal
and ventral bundles; I was, however, quite unable to detect any
bifurcation at the free extremity of these setee, and I examined them
with the highest power at my disposal (Zeiss’s F lens with eyepiece).
I could not detect the nephridia.

In the colourless integument and in the presence of two kinds of
setz this species evidently offers a transition to the Naidomorpha.

iv. On Clitellio and Limnodrilus.

These two genera, usually regarded as distinct, have been united
by M. Vaillant in the recently published third volume of the
‘Annelés’ in the ‘Suites 4 Buffon.’ |

M. Vaillant considers that the alleged absence of a prostate in
Clitellio is not a sufficient difference.

As a matter of fact, my own paper’ upon Clitellio showed other
points of difference besides the absence of the prostate; the main
distinction between the two genera, in addition to the want of a
prostate, is the existence of two pairs of perivisceral trunks, which
are specially enlarged and are contractile: I did not refer very defi-
nitely to their contractility in the paper cited, but I have since re-
examined the species Clitellio arenarius and find that these dilated
trucks are contractile, one pair contracting before the other. Now
the fact of the existence of contractile trunks does not distinguish
Clitellio from Limnodrilus. Limnodrilus has also two pairs of con-
tractile periviscerals, but only one pair of these are dilated ; whereas
in Clitellio both pairs are wide tubes. This difference, at any rate,
applies to the species of Limnodrilus known up to the present.

I take this opportunity of mentioning that Clitellio arenarius
has, like Limnodrilus, a supra-intestinal blood-vessel. But I could
find no integumental blood-capillaries such as are found in Limno-
drilus. I looked for them very carefully, of course in living worms.

So far, therefore, my observations have rather tended to accentuate
than remove the differences between Clitellio and Limnodrilus.

I have, however, found in a species of Limnodrilus an intermediate
form between Clitellio and the typical Limnodrilus. This species
is from New Zealand ; I have already * recorded its occurrence in
the South Island, though I was in error in stating that it presented
no differences from the European species.

As a matter of fact, this New Zealand Limnodrilus has, like Cli-
tellio, two pairs of greatly dilated hearts in segments viii. and ix. ;
there are no reasons for disbelieving that these wide trunks are

contractile. This species is, of course, freshwater in habitat. It
was found in a forest-pool along with Phreoryctes smithit.

None of the specimens were mature, so I am unable to say how
far they may agree with Cliteliio in other particulars; but, in any
case, they have the two pairs of dilated vessels in viii. and ix. that
have hitherto served to distinguish Clitellio from Limnodrilus.

v. Ona new Genus (Kerria) intermediate between Acauthodrilus
and Ocnerodrilus.

Mr. J. Graham Kerr, who accompanied the ‘‘ Pileomayo Expe-
dition ’’ in 1890, has kindly given me a number of small Oligocheta
which he collected in the upper reaches of that river. They were
preserved with corrosive sublimate, and are in consequence in an
excellent condition for microscopical examination. There are alto-
gether about a dozen specimens, some fortunately being sexually
mature. «The water where they were met with was exceedingly salt
and bitter, but contained a number of other animals, notably a few
decapod Crustaceans. But animal life was not, Mr. Kerr informs
me, very abundant in the stream. So far as I am aware, no Oligo-
cheete of any kind has ever been described from a locality like the
present, except a species of Pachydrilus referred to by Semper as
occurring in the brine-springs of Kissingen in Germany. Salt water
is not, however, entirely inimical to the existence of Oligocheta,
for there are a few species known from the sea-shore ; for example,
Clitellio, referred to in the present paper, Pontoscolex, Pontodrilus,
&c. I expected, therefore, that these worms would prove to be
interesting, and my expectations were realized.

The worms are all very small, an inch to an inch and a half in
length by 1 mm. in diameter. They are about the size of, and re-
semble in general appearance, Ocnerodrilus eisent, and I at first was
disposed to refer them to the same genus at least. Although a
more careful examination of the worms showed that they could not
be referred to the genus Ocnerodrilus, it became very soon evident
that they were nearly related to that genus; they serve, in fact, to
indicate the probable relations of Ocnerodrilus, concerning which I
was formerly in doubt’. Eisen, the original describer * of the genus
Ocnerodrilus, placed it in the family Lumbriculide. This conclusion
was subsequently abandoned by Eisen himself *, and I have myself *
endeavoured to combat it ; the genus is clearly to be referred to that
very large and imperfectly known group of worms which I have
called Cryptodrilide. I do not propose to give a detailed systematic
account of the anatomy of this new worm, but merely to dwell

upon its salient characters, particularly those which bear upon its
affinities.

The setze are strictly paired and show no noteworthy peculiarities ;
they are not in any way modified upon any segments of the body.
The clitellum occupies segments xiv. to xix.

The alimentary canal is chiefly remarkable for two points: there
is a gizzard present, not a very usual occurrence with aquatic
Oligochzta. The gizzard, moreover, is well developed ; it lies in
segment vii.

In segment ix. are a pair of calciferous pouches ; these are com-
plicated in structure, being composed of a much-folded cellular
membrane. Although the segment which they occupy is the same
as that which in Ocnerodrilus contains a pair of cesophageal diver-
ticula, the organs are simpler in their minute structure in the latter
genus.

Some of the anterior mesenteries, as is usually the case in Oligo-
cheeta, are thickened ; this statement applies to those which separate
segments v./vi., vi./vii., Vii./vill., viii./ix.

The nephridia are present in the genital segments ; the posterior
set are invested by a thick layer of peritoneal cells.

The genital organs conform in almost every particular to the plan
met with in the genus Acanthodrilus, and are illustrated in the
accompanying drawing (woodcut, fig. 1).

On segments xvii. and xix. are the openings of the atria; the
actual pores are placed upon the summits of elevations near to the
median ventral line of the body. The atria, like those of other
Acanthodrilide, are divisible into two regions: with the actual orifice
is connected a narrow muscular tube ; this widens out distally into a
glandular tube, but this glandular tube is lined by a single layer
only of cells. In no species of Acanthodrilus, so far as I am aware,
is this the case. Even in smaller species than the one described
here the glandular part of the atrium has two layers of cells, resem-
bling, as I have pointed out, the structure of the clitellum. On
the other hand, Ocnerodrilus has an atrium which is exactly like the
present species in having a lining of a single row of cells. These
cells are tall and very granular in appearance. ‘The atrial pores are
close to the ventral pairs of sete ; there are no penial sete. Penial
setz are only rarely absent from Acanthodrilus ; A. multiporus and
an allied species are the only forms which I can recollect that are
thus deficient.

On the xviiith segment open the vasa deferentia: there is only a
single vas deferens on either side ; it runs in close contact with the
body-wall, not embedded init. In the xth segment the vas deferens
widens out to form a funnel ; this funnel is not only very large but
very much folded, and occupies the greater part of the segment in
which it lies. It struck me as being unusually large ; there is only
one funnel on each side.

The same segment, i. e. the xth, contained the single pair of
testes. Asa general rule, when there is a single pair of testes
these gonads occupy the xith and not the xth segment. In the

present species, however, there is no doubt of their lying in the xth
segment.

The sperm-sacs are in segments x. and xi. They partially involve
the testes and vas deferens funnels. The ovaries are, it is almost
unnecessary to state, placed in segment xiii. The oviducal funnels
open opposite to them ; the ovaries are so large that but little room
is left between the end of the ovary and the funnel; I saw an ovum
within the mouth of the oviduct. There are no egg-sacs. The
oviducal pores are upon the xivth segment.

In the viiith and ixth segments are the spermatothece. These
organs are large sacs, communicating with the exterior by means of
a comparatively long duct; they were densely packed with sperma-
tozoa, but had no diverticula.

It is evident from the above short and, in some respects, incom-
plete account of the Pileomayo worm that it is most nearly allied to
the genus Acanthodrilus. That genus, it should be remarked, is
one which is less uniformly terricolous than any other genus of
‘*earthworms.” There are already several species known to occur
in water. Among them are Acanthodrilus stagnalis, A. dalei,
A. schmarde. This is, however, the first species which has been
met with in saline waters.

The other aquatic Acanthodrilide show no particular affinities to
aquatic genera; but the present species does; and it distinctly
approaches Ocnerodrilus. The resemblance is not only in the sim-
plification of the structure of the atria; that of itself would not
perhaps be a very important fact, since it might be put down merely
to degeneration. A more important point of likeness is the existence
of the single pair of cesophageal diverticula in segment ix. ; this par-
ticular segment is not a usual one in which to find these calciferous
glands. Besides, in other Acanthodrilids there are nearly always
two or three pairs of these glands situated further back.

Very little is wanting to convert the species here described into
an Ocnerodrilus ; to refer it definitely to the genus Acanthodrilus
would be to ignore the characteristic differences which it shows from
that genus, with which, however, it undoubtedly agrees in all those
points which are made use of to define the genus Acanthodrilus.
On the other hand, it can hardly be put in the genus Ocnerodrilus.
The principal difficulty in the way of this is the two pairs of atria
and their position. The fact of there being two pairs of atria
instead of one only would not deter me from this step ; I think, for
instance, that the genus Neodrilus must be merged in Acanthodrilus.
The important difference appears to be the separation of the atrial
and vas deferens pores by a septum in Acanthodrilus. If it were not
for the position of the calciferous glands all the resemblances between
this worm and Ocnerodrilus might fairly be set down to a con-
vergence due simply to degeneration. As it is I am inclined to
think that it will be necessary to institute a separate genus for this
Acanthodriloid worm from the Pileomayo; and I propose to call
it Kerria, after Mr. Graham Kerr, with the specific term halophila.
It may be useful to compare, by means of the following table, the

present species with some allied forms. The table (p. 359) gives
some additional facts not referred to in the above description. Also,
I introduce a few worms not yet fully described, which I have
recently been studying.

The position of the external apertures of the male reproductive
apparatus is, however, rather different from what is found in the
genus Acanthodrilus. The accompanying figure (fig. 2) illustrates

the arrangement in an individual which was studied by means of
longitudinal sections ; I found it impracticable to examine the ven-
tral surface of the entire worm mounted in glycerine, for the reason
that in the course of preservation a good deal of the corrosive sub-
limate used as a fixing reagent had crystallized upon the integument,
rendering it therefore very opaque. In the sections the setee were
seen to be quite unaltered upon the genital segments, they were not
even larger than those upon the neighbouring segments. The atrial
pores, as well as those of the vas deferens, are in close relation to

the ventral pair of setee: the anterior atrial pore of one side of the
body lies a little in front of, and to the outside of, the pair of setze :
the posterior atrial pore, on the other hand, has a slightly different
relation to the pair of setz of its segment; it is placed a little behind
the set. The pore of the single vas deferens again differs in posi-
tion from both of these apertures ; it lies on the same level as, but to
the outside of, the ventral setze of its segment, which is of course
the xviiith, I am disposed to believe that Rosa’s ‘‘ Acanthodilus ”’
spegazzinii will prove to be congeneric with this species.

6. On the Systematic Position of Notoryctes typhlops. By
Hans Gapow, Ph.D., M.A., Lecturer on Advanced
Morphology of Vertebrata, and Strickland Curator,
University of Cambridge.

[Received April 9, 1892.]

Professor Stirling had kindly entrusted me with his most valuable
material of Notoryctes before this was distributed to various
museums. He asked me to fix the systematic position of this new
mammal more precisely than he had been able to do, because of
want of time and opportunity. He also modestly wanted me to
verify and to supplement his own work *. This was both an easy and
a difficult task. His two papers on Notoryctes contain a most
carefully worked out description of the creature, and, with the ex-
ception of some important characters concerning the teeth and the
cloacal region, leave nothing that could be of general interest and
bear upon the question of the position of Notoryctes in the system.
There are still some points which have not been worked out fully,
e.g. the vascular, muscular, and nervous systems, but these will
undoubtedly be investigated in due time.

Professor Stirling has discussed the whole matter with me
thoroughly during his several visits to Cambridge ; several parts of
Notoryctes we redissected together and many questions were studied,
so that the following pages might well form a paper of conjoint
authorship; but, unfortunately for me, his time in Cambridge was
limited, and thus I have become the only responsible author.

The advance copy of the ‘ Handlist of Australian Mammals,’ by
Mr. J. Douglas Ogilby, contains many important remarks on the
systematic position of Notoryctes, with which we are unable to agree.
This has necessitated, unfortunately, more argumentative reasoning in
the following pages than would have been the case had Notoryctes
been left in a less ambitious position than that of a link between
the Proto- and Metatheria. The creature is interesting enough as a
Marsupial.

362 DR. H. GADOW ON THE SYSTEMATIC [May 3,

With regard to the investigation of the affinities of Notoryctes, I
trust that a word of warning will not be taken amiss. It concerns
the danger which may result from the frequent habit of selecting the
taxonomic characters from the skeleton only, to the exclusion of
other organic systems. In case of fossils this cannot be helped, and
we have then no further means of testing the validity of our con-
clusions. Now, supposing only the skeleton of Notoryctes were
known, while the teeth and soft parts and the land where it was
found were unknown ; or let us suppose, for argument’s sake, that it
“came from America,” neither an im possible nor an even improbable
assumption. In this case many a zoologist, provided he knew his
osteology well, would conclude that the skeleton in question
belonged to a small, burrowing mammal, which was closely allied to
the Dasypodide, especially to Tatusia, in fact that it was an
Edentate. This conclusion would be based upon the following
striking characters :—

1. Anchylosis of the second to sixth cervical vertebre. In Ta-
tusia peba anchylosis of vertebree 2, 3, and 4.

2. The extraordinary strength of the first thoracic rib.

3. The acromial process of the scapula is very long and curved,
and has a facet on its inner surface for the upper eud of
the humerus.

4. There is a second spine on the postscapular fossa ; both spines
enclosing a deep groove.

5. The clavicles are complete and are attached to the manubrium
sterni by the intervention of a ligament of some length. Cf.
Cholepus, &c.

6. The fibula has a large foramen near the proximal portion of
its shaft (cf. Stirling, p. 179, and fig. 7, pl. viii.). Such a
foramen is also present in the Cambridge specimen of
Tatusia peba.

7. There is a large sesamoid bone on the plantar side of the foot.

8. As many as six vertebree are anchylosed with the pelvis.

9. The caudal vertebrae possess movable chevron bones.

10. The type of the fore and hind limbs is decidedly fossorial.

We might go even further and insist upon some characters in
which No¢oryetes differs from all or from most Marsupials :—

1. The well-developed patella. Cf. Perameles.

2. The anchylosis of cervical vertebra.

3. The great strength of first thoracic rib.

4. The possession of six sacral vertebrze, instead of 2, 3, 4, or 5,
as Phascolomys platyrhinus.

. The fusion of the cuboid with the ectocuneiform bone. Unique.

. The decidedly fossorial type of the limbs.

. The apparent absence of marsupial bones; for these, while
scarcely visible without a lens, and not overlooked by the
careful describer of the first entire specimen, would certainly
be lost in a naturally bleached skeleton.

“NI &

1892. ] POSITION OF NOTORYCTES TYPHLOPS. 363

However, let us return to facts. Notoryctes occurs in the very
middle of Australia, and every important part of its anatomy is
known. Its teeth are not like those of any known Edentate,
although they are aberrant enough in number and position even for
Marsupials. It possesses a marsupium and an inverted inner
angular process of the under-jaw—two characters which are
together sufficient to prove that Notoryctes is a member of the
Marsupialia or Metatheria in the sense hitherto defined and accepted.

Mr. Douglas Ogilby* has naturally and correctly placed Noto-
ryctes as a separate family among the Polyprotodontia of the
Marsupialia, but he hopes that “ we have now obtained a definite link
between the Proto- and Metatheria subclasses, a link which will
perhaps eventually bridge over the gulf which at present separates
the Monotremes from the Marsupials.” A definite link would
certainly, not perhaps eventually, bridge over that gulf, but unfor-
tunately that much hoped-for link is still missing ; certainly it is not
represented by Notoryctes.

The Monotremes are characterized by the possession of :—(1) a
typical cloaca; (2) a Saurian shoulder-girdle, 7. e. an episternum
or interclavicle, clavicles, complete coracoids, and considerable
remnants of the ventral halves of precoracoids (epicoracoids of some
authors). Additional characters are :—(1) absence of functional
teeth in the adult; (2) a temporary marsupium without nipples.

Notoryctes differs in every one of these four points from the
Monotremes and agrees with the Marsupials.

I. The cloacal arrangement appears at first sight strikingly like
that of the Monotremes. The accompanying drawings (see p. 364)
will explain the points better than a lengthy description. It must
be borne in mind that there are Metatheria without a functional
marsupium, while in the Prototheria this organ is functional ; like-
wise there are monotrematous mammals besides the Prototheria.
Marsupium and cloaca, taken alone, are therefore not sufficiently
diagnostic for the separation of Proto- and Metatheria: they are
differences of degree only, the intermediate links being furnished
by the various Marsupialia themselves. I have shown elsewhere *
that in the Marsupialia the urogenital and rectal openings are not
completely divided off by a partition, there being still one common
external opening which leads into a common, although mostly
shallow chamber, viz. into the proctodeum or vestibulum cloace.
In both male and female Marsupials (figs. 4 and 6, p. 364) the
urogenital sinus is still of considerable length, and is completely
shut off from the rectum, while in the male Monotremes (fig. 1) the
urine passes into a urodzum, or middle chamber of the cloaca above
the penis. In Notoryctes and in all other Marsupials, this separate
exit of the urine and of the genital products is made impossible by the
completion of the fold #. Urine and sperm pass through the penis
in the male, and in the female the ovarial products (eggs or foetus)
have the same channel as the urine. This channel is the same in

the Marsupials, Notoryctes, and the Monotremes, and is morpho-
logically the same through which runs the urine in the male Mono-
tremes.

II. The shoulder-girdle of Notoryctes is built after the Marsupial
type ; it shows the complete absence of an interclavicle, of coracoids,
and of “ epicoracoids.” As confirmatory evidence of the affinities
of Notoryctes with the Monotremes, Mr. Ogilby mentions “the
considerable development of the clavicle, which is connected by
ligament to the sternal apparatus, along with the rudimentary
character of the epipubic bones being also Monotrematous.” The
clavicles of Notoryctes are weak, their sleuderness of function is
obviously indicated by their long ligamentous connexion with the
manubrium sterni. In the Dasyures and in the Bandicoots the
clavicles are very rudimentary or even absent, while in the Mono-
tremes they are, by means of a large interclavicle, fastened to the
sternum as firmly as possible. ‘‘It may be sought to explain away
this difference in the strength of the shoulder-girdle on the grounds
that Wotoryctes, Echidna, and Ornithorhynchus have the fore limbs
strengthened in order to enable them to burrow with the greater
ease ; but the superficiality of such a view is demonstrable at a
glance, if we take into consideration the fact that the Peramelide,
which are also of fossorial habits, though not in so marked a degree
as the genera mentioned above, are absolutely without rudiments of
these bones.”” This may be, but the composition of the shoulder-
girdle and sternal apparatus of Notoryctes is one of the strongest
proofs against its Monotreme affinities. Its ancestors had lost the
very strength of the sterno-scapular and humeral support which is
so essential to an intensely fossorial animal, and its organism has
resorted to a new device of giving strength to the chest by an extra-
ordinary development of the first pair of ribs. The latter firmly
fix the anterior portion of the sternum and secure the development
and working of strong pectoral and humeral muscles. A similar
case is afforded by the Dasypodide. Is it more likely that a
burrowing, digging creature like an Echidna would give up its
strongly secured chest, or that a Marsupial (which as such had lost
coracoids and interclavicle, and obeys the general law that parts
once lost by reduction cannot be redeveloped) which assumes
strongly fossorial habits would resort to strengthening some of those
parts which it does possess, namely ribs, in order to attain a similar
result ?

How the rudimentary character of the epipubic or marsupial
bones of Notoryctes can be used as evidence of its affinity to Mono-
tremes is not obvious, considering that in both Hehidna and
Ornithorhynchus these bones are much stronger and larger than in
any Marsupial. :

III. The marsupium seems to be a permanent organ in the female
Notoryctes, and a pair of minute mammary prominences, devoid of
hair and ending in nipple-like projections, have been discovered by
Professor Stirling. This is likewise a Marsupial, not a Monotrema-
tous character. The pouch in Notoryctes opens backwards towards

Proc. Zoou. Soc.—1892, No. XXVI. 26

366 DR. H. GADOW ON THE SYSTEMATIC [May 3,

the anus: this is probably a character adapted to the fossorial
habits of the creature, a parallel case being afforded by Perameles.
It would be rash to infer from this similarity any special affinity
between these two genera.

IV. The teeth are built after the zoophagous marsupial plan; it
is, however, significant that the crowns of the teeth of the Dasyuride,
and especially those of Myrmecobius, show the same type of struc-
ture as those of Ornithorhynchus (cf. Poulton and Leche’). The
teeth are present in considerable numbers, and, with the exception
of a few, remain functional throughout life. There is no indication
whatever of their becoming superseded by a horny covering of the
jaws, the naso-frontal horny shield of Notoryctes being a special
feature which has no resemblance to, or connexion with, the covering
of the jaws of the Monotremata.

The determination of the full number of teeth was wisely left in
abeyance by Prof. Stirling, although he suggested the following

Probably the two upper and the two lower premolars represent the

mens A and B, and in the right mandible of female I.

Pm. 1 is canine-shaped, projecting above the incisors and the
canine ; it is present in both sides in males I., II., V., females III.,
IV., and specimen C.

Pm. 1 is very much reduced to a short pointed weak tooth in the
right side of specimen B and female I., in both sides of specimen A.

Pm. 1 is absent in the left mandible of specimen B.

The canine tooth, i.e. the fourth in the series, fitting upon the
fourth upper tooth, which latter is implanted immediately behind
the premaxillary suture, is generally weaker than the incisors, never
projects above the series, and shows occasionally a slightly uneven
crown. The lower canine is thus fully developed in the right side
in males I. and II., female I., and in specimens A, B, and C.

The canine is reduced to a very small pointed tooth on the left
side in males [., II., V., and in female I.

The canine is reduced on both sides in female IIT.

The canine is absent on the left side in female IV., in specimens
A, B, and probably in C.

Concerning the incisors, they diminish in size from the first to the
third. In most specimens three incisors are present in both man-
dibles, but in the left of female IV. and of specimen C there are
only two incisors, which in female IV. are followed by a gap in front
of the first premolar, and in specimen C by a smaller gap in front
of the reduced canine.

Comparison of these nine apparently adult specimens shows the
tendency of reduction of the left lower canine and of either pm. 1 or
pm 3. The reduction, resulting ‘often in ultimate loss, seems quite
irregular, there being apparently no compensation effected by the
size of the neighbouring persisting teeth.

The most remarkable feature is, however, that the reduction
either in numbers alone, or in size, or in both is undoubtedly greater
in the left mandible than in the right. This fact seems well
established, considering that out of the nine specimens examined
the left-sided reduction is greater in not less than eight specimens ;
reduction in size alone in three, in numbers in five specimens.

The total number of teeth in the nine right mandibles is 86, in the
corresponding left mandibles only 79. The number of reduced and
of absent teeth on the right side is 11, on the left side 19. Sucha
decided asymmetry is practically unique; I have failed to perceive
any corresponding asymmetry in the size of the two mandibles.

The teeth in the upper jaw are much more regular. Three
incisors are followed by an equally small canine. The first of the
premolars is small, the second large. The four molars are always
present and do not vary in size.

In specimen C the right and left upper sides possess each only 9
teeth, the third right incisor has been lost and has left a gap, while
on the left side the canine seems to be absent without a distinct gap.

In female IV. left side, and in female I. right side, there are like-
wise only 9 teeth; the four molars are complete and so are the two
premolars, while the canines seem to be absent, with perhaps a

slight gap. ee

368 DR. H. GADOW ON THE SYSTEMATIC [May 3,

The tooth formula of Notoryctes differs consequently from that of
all other known Polyprotodonta in the smaller number of incisors,

namely 5 against ; in Didelphide, 3 in Peramelide, and ; in Dasyu-
ride; while the number of premolars, , agrees with that of Dasyu-

rus against Didelphide, Thylacinus, Thylacoleo, Phascologale, some
Perameles, and Myrmecobius, in all of which the original fourth
premolar is still present.

While it was easy enough to disprove the existence of any Mono-
trematous affinities in Notoryctes and to refer it to the Marsupials,
the question to which of the families of existing Marsupials
Notoryctes is nearest related is rather difficult. Mr. Ogilby prefers
to look upon it as an aberrant Polyprotodont, and he has based this
opinion on the character of the teeth alone, with this reserve that,
if canine teeth be absent (as he himself has suggested) it is not a
typical Polyprotodont, but a true link between the Monotremata
and Polyprotodonts. This reasoning is not quite obvious. If

1892.] POSITION OF NOTORYCTES TYPHLOPS. 369

his own suggestion as to the incisor nature of the so-called canines
were correct, the creature would of course be an aberrant Polypro-
todont ; but this absence of true canines would not affect. its
Marsupial affinities, and would not in any way bring it nearer to the
Monotremata, because we know several genera of true Marsupials
which have no canine teeth. I have shown that Notoryctes is
aberrantly polyprotodont in spite of the presence of canine teeth.

The enumeration of the following characters of Notoryctes will
perhaps help to settle its affinities :—

A. Characters which prove Notoryctes to be a member of the
Metatheria.

1. Possession of an apparently permanent marsupium, with two
localized mammee and nipples.

2. Well-developed inner angular process of the mandible.

B. Characters of Notoryctes which occur also in some Metatheria.
1. Large movable chevron-bones in the caudal vertebree: Ma-

cropus, Dasyurus, &e.

2. Acromion much elongated and curved over the humerus:
Dasyurus.

3. Large osseous bulla auris: Peragalea (Macrotis) lagotis,
Perameles, Dasyurus ursinus, Phascologale.

4. Very rudimentary marsupial bones: Thylacinus.

5. Opening of marsupinm directed backwards: Perameles.

6. Presence of a prehallux, i.e. the “ sesamoid ” bone attached
by ligament to the entocuneiform, described by Stirling,
p. 180, pl. viii. fig. 8s. Occurs also in Didelphys.

7. Presence of an osseous patella: Perameles.

8. Clavicles not directly attached to sternum, but by inter-
vention of ligaments. A precoracoid unossified segment is
usually present in Metatheria.

9. Presence of a “ meso-scapular segment.” Usual in
Metatheria.

C. Characters of Notoryctes, not found in recent Marsupials: see
numbers 1, 2, 4, 6, 7, 8 of Edentate resemblances (p. 362) ;
further, in opposition to Monotremata, the prepenial, extrapelvic,
not abdominal position of the testicles combined with the absence

Snake 5
of ascrotum. Lastly, = incisors.

D. Character unique in Notoryctes: fusion of the cuboid with the
ectocuneiform of the foot.

It so happens that the characters enumerated above do not permit
any decided conclusion, except that Notoryctes might be looked
upon as a ‘* very old and generalized form” which has some charac-
ters in common with almost every other existing Marsupial family.
But this not unfrequent mode of cutting the knot of the difficulty
of settling the systematic position of a peculiar nature will hardly
be advisable in the face of the highly specialized structure of Voto-
ryctes.

We have to make further inquiries. Notoryctes is fossorial to an

370 ON A WILD CAMEL FROM EASTERN TURKESTAN. [May 17,

exaggerated extent and it is insectivorous. Consequently the feet
and the cecum might give some hidden clue as to its affinities.

The toes of the hinder extremities have to be considered as free.
There is at the utmost a very slight indication of syndactylism of
the second and third toes, far less obvious than it is even in Phasco-
lomys. In its free toes Notoryctes agrees with Didelphide,
Dasyurus, Thylacinus, Phascologale, Myrmecobius, Phascolomys.

The hallux is complete and functional, as in Didelphide, Phasco-
logale, Phascolomys ; this character excludes Dasyurus, Thylacinus,
Myrmecobius, Antechinomys.

The pronounced syndactylism and the well-developed cecum of
the Phalangistine, Phascolarctos, Perameles, Cheropus, and the
Macropodide exclude these families from comparison.

The structure of the foot invites, therefore, comparison of
Notoryctes with Didelphide, Phascologale, and Phascolomys; the
latter is excluded by its herbivorous life and by its Diprotodont
teeth. The comparison is now restricted to the Didelphide and to
certain Dasyuride, especially Phascologale.

The geographical distribution of the Didelphide would remove
them from Notoryctes, but it is to be remembered that the Didel-
phide seem to be the lowest and most “generalized” of existing
Marsupials, and that in bygone times they had a much wider
distribution. Chironectes shows that the Didelphide are capable ot
a great amplitude of adaptation, namely to arboreal and to aquatic
life. However, it is unnecessary to go so far afield in the search of
the nearest kin of Notoryctes. Through the possession of an
element of a prehallux, Notoryctes, like the Didelphide, stands below
the Dasyuride ; in the reduction of its teeth it is further advanced
than the latter. Although its numerous Edentate resemblances are
clearly all acquired owing to its mode of life, they are important
enough to give Notoryctes the rank of a family of the Polyproto-
dont Marsupials, as has been done on other grounds by Mr. Ogilby,
this family being nearer allied to the Dasyuride than to the
Peramelide.

May 17, 1892.
Prof. Flower, C.B., LL.D., F.R.S., President, in the Chair.

Mr. W. T. Blanford exhibited for Major C. 8. Cumberland the
skin of a Wild Camel obtained by the latter in Eastern Turkestan, as
described in ‘ Land and Water’ for April 4th, 1891, p. 412, and ex-
pressed his belief that this was the first wild Camel’s skin that had
ever been brought to this country. Major Cumberland had hoped
to be present, but was unfortunately prevented by illness. He had,
however, sent the following notes to be read to the meeting :-—

“ The habitat of the Wild Camel is the Gobisteppe from Khotan
to Lob Nor. Except when snow lies on the ground these animals
may be met with here and there along the old bed of the Yarkand

1892.] ON BIRDS FROM PERU. 371

and Tarim rivers, which they frequent for the pools of brackish water
that are to be found here and there. But as soon as the snow falls
they move off into the desert, as if then independent of the water-
supply. They prefer the snow, I imagine, as being less salt than the
water, although it also is impregnated to a certain extent soon after
it falls. The Camel is very shy in its habits, and, so far as I could
ascertain, has never been caught and domesticated. The natives told
me that no horse in the country could catch the Camels in the deep
sand of the region they frequent. They appear to me to be distinct
from the Bactrian Camel; they are less stumpy in build, the hair is
finer, closer, and shorter. They vary in colour, like the domestic
species, from dark brown to lightish dun. Their origin has yet to be
traced. I take it that they have sprung from Camels which escaped
when the district known as Takla Makan was buried in a great sand-
storm some centuries ago. Tradition relates that no human beings
survived, but it is likely enough that some of the Camels and Horses
did so, and that this was the origin of the Wild Camels and Ponies
which are found in this district.”

Mr. Blanford added that he had compared the skull of Major
Cumberland’s specimen with one of a Bactrian Camel in the British
Museum. There was some difference, but without a much larger
series it was impossible to say whether the difference was sufficient
to indicate a distinction of race. In the rather small details in which
C. bactrianus differs from C. dromedarius the Wild Camel skull
agreed with the former, as it should do, for the skin was that of a
two-humped Camel, although, as Major Cumberland had noticed,
the humps were very small and represented by tufts of long hair.

i, Liste des Oiseaux recueillis par M. Jean Kalinowski dans les
environs de Lima et d’Ica (Cote Péruvienne).

M. Jean Kalinowski, explorateur intrépide du Kamtschatka et de
la Corée, est parti en 1889 pour le Pérou en qualité de correspon-

372 MM. H. VON BERLEPSCH AND J. STOLZMANN [May 17,

dant du Musée des Comtes Branicki & Varsovie. I] a commencé
ses recherches ornithologiques par l’exploration des environs de
Lima et d’Ica. Voici la liste des localités ot il a fait des collec-
tions :—

Lima—capitale de la république. Callao—port principal du
Pérou. -Ancon—petit port au nord de Lima. Magdalena Vieja et
Chorillos—petites villes au sud de la capitale.

Tea—capitale du département de ce nom, située 4 la céte (14° 4’
33" lat. S.). Dans le voisinage se trouvent les haciendas Huamani,
Trapiche et Ocucaje.

La faune ornithologique des environs d’Ica parait presque identi-
que avec celle de Lima, c’est pourquoi nous n’avons pas separé dans
la liste les oiseaux recueillis dans ces deux localités. Cependant il
y a une espéce d’oiseau trouvée a Ica par Kalinowski qui n’est pas
encore connue comme habitante des environs de Lima et peut-étre
ne se répandra pas si loin au nord, tandis qu’elle est connue des
parties plus méridionales de la céte: c’est le Xenospingus concolor.

Des $0 espéces d’oiseaux trouvées par M. Kalinowski dans les
environs de Lima et d’Ica il parait que 10 espéces n’étaient pas
encore mentionnées comme habitantes de ces localitées, savoir :—

Progne purpurea. Asio clamator.
Pyranga testacea tschudi. Ardea egretta.
Xenospingus concolor. Ardetta ewilis.
Dolichonyx oryzworus. Tringoides macularius.
Tyrannus tyrannus. Numenius hudsonicus.

Tous ces oiseaux étaient déja connus comme provenants du Pérou,
sauf |’ Ardetta evilis, qui n’est pas mentionnée dans ‘Ornithologie
du Pérou’ par le Dr. Taczanowski.

Il y a aussi un Theristicus (Th. melanopis) déja connu de Lima,
qui n’est pas décrit dans Pouvrage de Taczanowski, qui l’avait con-
fondu avec une autre espéce du Haut Pérou nommée par lui Th.
caudatus (Bodd.), mais qui en différe également et devrait peut-étre
recevoir un nouveau nom. C'est le méme cas avec le Chrysoptilus
atricollis de YOrn. du Pérou, iii. p. 86.

Il nous a paru nécessaire de décrire comme espéces nouvelles ou
sous-espéces nouvelles quelques oiseaux déji mentionnés de ces loca-
lités, mais confondus avee d’autres espéces et cités sous des dénomi-
nations fausses. Les voici :—

Pyranga testacea tschudii, subsp. nov.
Saltator immaculatus, sp. nov.

Dives kalinowskii, sp. nov.

Pyrocephalus rubineus heterurus, subsp. nov.
Cinclodes taczanowskii, sp. nov.

Nous avons aussi donné un nouveau nom au Molothrus autrement
nommé M. purpurascens (Hahn), mais qui n’est pas le M. purpu-
rascens de cet auteur. Nous lui avons imposé le nom de M. oeci-
dentalis.

Toutes les peaux recueillies par M. Kalinowski sont d’une qualité

excellente et sont pourvues d’étiquettes contenant les indications de
Phabitat, du sexe, des mesures, du couleur d’iris etc. Les mesures
relatives 4 la longueur totale et l’envergure des ailes sont prises par
M. Kalinowski des exemplaires frais avant de les dépouiller, de
méme que les couleurs des yeux, du bec et des pattes.

Note.—Il faudra probablement séparer les oiseaux de Guayaquil
comme espéce distincte ou comme race locale, Les oiseaux de
l’Ecuadeur sont plus petits, ayant le bec, les ailes et la queue sensible-
ment plus courts. La poitrine parait plus squamulé parce que les
plumes sont d’un brun plus obscur vers la base, et bordées d’un
blanc plus pur 4 la pointe. Le blanca la pointe des rectrices ex-
ternes est plus étendu. Le spéculum blanc formé par les pointes
des tectrices des remiges primaires également plus étendu. La strie
sourciliére blanche ne s’étend pas au-dessus des freins, ce quest le
eas chez le M. longicaudatus typique du Pérou. Il faudra bien
examiner les types du Mimus leucospilos, Pelzeln, et du M. nigri-
loris, Lawr., qui sont décrits par méprise comme provenants du
Chile et du Mexique, s’ils appartiennent peut-étre 4 la forme qui
habite I’ Ecuadeur.

Les oiseaux de Lima ressemblent beaucoup aux oiseaux typiques
de Bahia. En général ils sont un peu plus pales et un peu plus
petits, ce que se manifeste le plus dans la longueur de la queue.
Ces points de différence ne paraissent pas é@tre constants. Dans
tous les autres détails ils s’accordent trés bien avec les oiseaux de
Bahia.

I] parait que cette forme du T. musculus a été nommé par Lesson
T. murinus (Less. Rev. Zool. 1844, p. 434, “du Pérou’’).

Les trois ceufs recueillis par M. Kalinowski 4 Lima sont d’un
blanc légérement teint de rosé, couverts de petites taches d’un roux
rouillé. Ces taches forment une couronne dense autour du gros
bout et sont assez rares sur le reste de la surface. A la gamme
inférieure les taches sont d’un cendré-violatre péle. Dimensions
18x13; 18x13; 18°25x13 mm.

Le T. darwini était décrit par Bonaparte comme provenant du

Ces oiseaux ressemblent aux oiseaux typiques de |’ Ecuadeur
oriental, mais le croupion est d’un jaune plus pur, le jaune a la base
des rectrices plus étendu, et le miroir alaire plus grand. Quant a
ces détails ils paraissent un peu intermédiaires entre la Ch. capitalis

Ces oiseaux s’accordent tout-a-fait avec des individus de |’ Eeua-

Une ponte de trois ceufs a été trouvé par M. Kalinowski 4 Lima
le 9 novembre. Les ceufs sont ovoides, légérement amiucis vers
le petit bout, qui est assez fortement retroussé. Le fond est bleu-
verdatre pale, comme dans les ceufs des autres espéces de Sycalis.
Le fond est couvert de taches d’un roux-brunatre, ramassées princi-
palement au gros bout, ot elles forment une couronne plus ou moins
dense. Le reste de la surface est couvert de taches plus rares et
plus petites ; le petit bout reste quelquefois immaculé. La gran-
deur des taches varie beaucoup, depuis petits points a peine visibles
jusqu’a macules de quelques millimétres en diamétre. En général
les grosses taches sont rassemblées sur le gros bout, ow elles couvrent
parfois le fond. Celles de la gamme inférieure sont d’une couleur

Deux ceufs ont été fournis par M. Kalinowski, qui les a trouvé
dans les environs de Lima. Ils sont presque elliptiques, courts, et
bombés aux deux bouts presque également retroussés. La coque
est lisse, avec un éclat assez fort. Le fond est blanc, légérement
bleudtre, parsemé sur toute la surface de petits points brun-olivatres,
un peu plus denses sur le gros bout que sur le reste de la surface.
Dimensions 24°25 x 19; 22°25 x 18°25 mm.

Les oiseaux de Lima ont le bec un peu plus long, mais les ailes
plus courtes que les oiseaux de l’Ecuadeur occidental. L’espéce a

le cas chez les oiseaux de Lima et d’Ica. L’oiseau de Tumbez a

Ces oiseaux ressemblent le plus aux oiseaux du Chile. Ils ne
différent que par les ailes et la queue un peu plus longues. Les
bandes formées par les points claires des tectrices sus-alaires sont
moins prononcées, plus verdatres au lieu de grisatres. La gorge et
la poitrine d’un gris un peu plus clair.

34. My1oBIus RUFESCENS, Salvad.

Lima: quatre oiseaux de septembre et novembre 1889. “ Iris

Les deux ceufs trouvés par M. Kalinowski a Phacienda Ocucaje
le 10 décembre 1889 ont le fond d’un ocreux-roussatre pale, varié
d'une couronne disséminée, composée de petits points d’un roux-
rouille foncé. Le reste de la surface est uniforme. La grandeur de
ces points ne dépasse pas celle de la fiente de la mouche ordinaire,.

Chaque point est entouré d’une nuance roussatre plus foncée que le
fond. Les poiuts de la gamme inférieure tirent au cendré. Dimen-
sions 18°25 x 13°25; 17°75 x 13°25 mm.

Le Mytobius rufescens, Salvad., a été décrit comme provenant du
Brésil. Il serait peut-étre 4 recommander «’e réexaminer le type qui
se trouve au Musée de Turin. En cas qu’il appartiendrait 4 une
autre espéce, l’oiseau du Pérou occidental devrait porter le nom de

blanchatre, ce qui n’est pas du tout le cas chez l’oiseau typique.
Les oiseaux de Lima nous regardons comme types de cette sous-
espéce nouvelle. Les oiseaux de l’Ecuadeur occidental ne s’en
distinguent que par les ailes et la queue un peu plus longues.

Cette espéce nouvelle, que nous avons nommée en mémoire 4 feu
notre ami le Dr. L. Taczanowski’, dans toutes ses formes s’accorde bien
avec le C. nigrofumosus (Lafr. et D’Orb.), dont le type venait de
Cobija, Bolivie. Cependant elle en différe bien par sa coloration.
Toutes ses couleurs paraissent plus pales et pius sombres, les dessins
blanchatres plus sales et moins tranchées. La différence principale
consiste dans la couleur de la poitrine et de abdomen, qui est d’un
gris-brun trés pale presque uniforme, au lieu d’étre d’un brun foncé
moucheté de stries blanches au milieu de chaque plume. Ce ne

Taczanowski autrefois avait communiqué 4 Berlepsch son opinion sur cet
oiseau, qu'il croyait déja espéce nouvelle —Brrt. et Stouzm,

sont que les plumes de la poitrine qui présentent des stries d’un
blanc-roussatre terne pas bien définies. Le blanc de la gorge et du
cou inférieur et latéral est plus sale, présentant une légére nuance
roussatre. Les plumes de ces parties sont bordées moins largement
d’un brun grisatre 4 leur pointe, tandis qu’elles sont plutot des
macules d’un brun intense qui terminent les plumes chez le C. niyro-
Jumosus. Toutes les tectrices sus-alaires présentent des points d’un
brun-blanc roussitre, tandis qu’elles sont d’un brun obscur uniforme
comme le dos chez |l’autre espéce. La bande rousse 4 la base des
remiges et les bordures rousses des petites tectrices des primaires
sont plus pales ou plus blanchatres. La strie sourcili¢re, composée
de stries d’un brun pale ou roussatre, est 4 peine visible, tandis
qu’il y a des taches presque blanches chez le C. nigrofumosus. Le
front est plus lavé d’un gris brunatre, le pileum plus noiratre.
Le dos d’un brun plus pale et plusenfumé. Le croupion beaucoup
plus pale et lavé un peu de roussatre. Les rectrices externes ter-
minées d’un roux plus pale et plus blanch4tre. Les tectrices sous-
caudales d’un brun terreux uniforme (pas stri¢ées d’un blanc rous-
sitre). Enfin, les tectrices sous-alaires d’un brun plus pale et plus
roussatre.

Malheureusement M. Kalinowski n’a fourni que trois femelles
adultes qui ont servi 4 la description précédente. Mais il est
improbable que le male différe beaucoup de la femelle. La com-
paraison a été faite avec un oiseau adulte du Chile du musée Ber-
lepsch. Aussi bien qu’on peut juger d’aprés la description de
MM. Lafresnaye et D’Orbigny du C. nigrofumosus, V oiseau typique
de Cobija, Bolivie, est identique avec celui du Chile.

Les oiseaux d’Islay, Pérou méridional, dont Sclater parle dans son
catalogue des Dendrocolaptide’, appartiendront peut-étre au C. tac-
zanowskii. 11 faudra les comparer.

paru bien distinct de nos exemplaires du Pérou occidental, qui sont beaucoup
plus petits que l’oiseau de la Bolivie. La différence dans la longueur de Vaile

Tl n’y a pas de doute que le nom de Tschudi “ decussata” serait

espéce par Mr. Sclater et d’autres. En outre Ja description de
Tschudi est trés bonne et ne peut pas étre appliquée 4 une autre
espéce. Tous les deux noms sont fondés sur des individus prove-
nants de Lima.

Il parait que dans son ‘Ornithologie du Pérou’ feu le Dr.
Taczanowski a confondu la St. decussata avec la St. bifasciata,
Gould, espéce plus grande qui habite le Chile et la Bolivie. Les
oiseaux décrits par lui comme St. bifasciata appartiendront sans
doute & la Sé. decussata. Quant a sa St. equicaudata il parait que
la description du male appartiendra aussi A la St. decussata, tandis
que la description de la femelle s’appliquera peut-étre A la femelle de
la vraie St. bifasciata, Gould (faite probablement d’aprés une femelle
de la Bolivie du musée Berlepsch). Les mesures du mile doivent
aussi avoir de rapport a la S¢. bifasciata, comme elles sont trop
grandes pour la S¢. decussata’. I] faut ajouter que dans la diagnose
de la St. e@quicaudata, Taczanowski dit “rectricibus lateralibus
ternis albo terminatis,” tandis qu’il dit dans les tables: ‘ Deux
rectrices latérales terminées de blanc.”

remarque seulement que le male unique qui lui a servi de type
venait du Pérou, il est presque certain que l’exemplaire en question
venait de la céte du Pérou, comme il était rapporté par l’expéddition
de “la Bonite.’” M. Taczanowski, dans son ‘Ornithologie du

qui vient des vallées chaudes de la sierra du Pérou septentrional et
qui parait étre nommé par Reichenbach (Handb. sp. Orn. Scans.

venait du Pérou par Warszewicz, qui a fait des collections dans les
montagnes du Pérou du nord.

L’espéce du nord différe surtout par la couleur du dos, qui est
d’un jaune pale (quelquefois méme jaune-orangé) traversé de bandes
noires aussi larges que les intervalles jaunes, au lieu d’étre olive
traversé de bandes noires de moitié plus étroites que les intervalles
olives, comme chez le Ch. atricollis, etc. On ne peut pas juger
d’aprés la description et figure mauvaise de Reichenbach, mais il
faudra examiner le type qui se trouve dans le Musée de Dresde.

Ayant comparé l’oiseau d’Ica avec un exemplaire du Brésil
(Minas Geraes) et deux individus de Colombie (Bogota et Antioquia),
nous avons trouvé des différences tres marquées. L/oiseau d’Ica
posséde une sorte de poche ou un sac tout-d-fait nu au milieu de la
gorge. Ce n’est que la partie supérieure de la gorge (ou le menton)
qui présente une ligne emplumée le long du milieu. Cette ligne
emplumée est séparée des plumes du cou inférieur par la poche nue
dont nous venons de parler. La poitrine inférieure est d’un roux
blanchdtre, formant une bande trés large (large de 60 mm. a peu
prés), séparée du cou inférieur, qui présente une couleur roussatre,
par une bande plus étroite (large de 25 mm.) d’un gris d’ardoise
couvrant la poitrine supérieure.

Les oiseaux du Brésil et de la Colombie n’ont pas une trace de la
poche (ou sac) gutturale. Ils possédent une large bande emplumée
le long du milieu de la gorge, qui se joigne en bas avec les plumes
du cou inférieur (sans interruption). Ce ne sont que les cdtés de la

390 MM. H. VON BERLEPSCH AND J. STOLZMANN [May 17,

gorge le long de la bande emplumée, le menton supérieur, et les
cétés de la téte autour de 1’ceil qui sont nus.

Le cou inférieur sur la poitrine est d’un roux plus intense, tirant
au chatain. Les autres parties inférieures (poitrine et ventre) sont
d’un gris d’ardoise uniforme, et il n’y a aucune trace d’une bande
roussatre sur la poitrine inférieure.

Chez l’oiseau d’Ica les cdtés de la téte et le cou entier sont forte-
ment lavés de roux (parties qui sont d’un blanc-roussatre chez les
oiseaux du Brésil et dela Colombie), mais on ne voit pas cette plaque
bien dessinée d’un roux chatain que les autres oiseaux présentent
sur le cou inférieur au commencement de la poitrine. L’oiseau d’Ica
présente des bordures plus roussatres aux plumes du dos et des
tectrices sus-alaires médianes. Les petites tectrices sus-alaires en
devant sont d’un gris d’ardoise (au lieu d’un noir d’acier) et bordées
d’un brun-roussatre 4 la pointe. En outre l’oiseau d’Ica a les ailes
et la queue plus courtes et les tibias plus dénudés.

Une étude attentive de la littérature nous a démontré que notre
oiseau d’Ica s’accorde parfaitement avec la déscription et figure du
“ Black-faced Ibis” de Latham (Synops. iii. 1. p. 108, pl. Ixxix.),
sur lequel Gmelin a fondé son Tantalus melanopis. L/’individu
décrit et figuré par Latham a été recueilli par le Dr. Forster dans
“ile “du Nouvel An,” prés de la Terre de Feu. Dans la planche de
Latham il se manifeste bien le sac nu jugulaire et le roux de la
poitrine inférieure séparé du cou par une bande noiratre. De méme
Gmelin disait dans sa diagnose ‘‘ saccus jugularis rugosus.”

De l'autre coté “le Grand Courlis de Cayenne” ou “Courlis &
cou blanc,” décrit et figuré par Buffon (Hist. Nat. Ois. viii. p. 47,
Pl. Enl. 976), qui forme la base pour le Scolopar caudatus, Bodd.,
s’accorde dans tous les détails avec nos oiseaux du Brésil et de la
Colombie. La planche de Buffon ne présente ni une poche ou sac
nu sur la gorge, ni une bande rousse sur la poitrine inférieure.
Aussi toutes les descriptions faites d’aprés des oiseaux du Brésil et
du Paraguay (du Prince Wied, Burmeister, Azara, etc.) s’accordent
avec la description et figure de Buffon et avec les individus du
Brésil et de la Colombie, dont nous venons de parler. Enfin Stolz-
mann a examiné des exemplaires provenants du Chile semblables 4
Voiseau d’Ica, et Berlepsch a vu dans le Musée de Vienne des
exemplaires du Brésil recueillis par Natterer qui s’accordent avec
Poiseau de Buffon.

Il est done évident qui’l y a deux espéces de Theristicus semblables
lune & l’autre, mais bien distinctes et habitantes de différentes
régions. L’une parait habiter le nord et l’orient de |’Amérique du
sud, par exemple Cayenne, Vénézuela, la Colombie, le Brésil et le
Paraguay, c’est le Th. albicollis (Gml.); l’autre habitera le sud et
Poccident & l’ouest des Andes, par ex. Magellania, Patagonia, Chile,
et la edte Péruvienne. C’est le Th. melanopis (Gml.). Il nous
parait qui] y a une troisiéme espéce habitante le Haut Pérou,
mentionnée par Tschudi et recueillie par Jelski dans les environs de
Junin, que nous avons l’intention de décrire dans un autre article.

Voici la synonymie des deux espéces de Theristicus, distinguées

du Th. melanopis. Il reste done douteux s'il y aura deux formes de Theristicus
au Chile ou si le Th. melanopis dans quelque age (ou sexe?) manquera du sac
sous la gorge. En tout cas les différences dans les couleurs des deux espéces
paraissent tout-a-fait constantes, et parmi tous les individus de l’orient que nous
ayons examiné (dont plusieurs tout-a-fait adultes) il n’y a pas un seul qui posséde
un sac sous la gorge ou qui manque de la strie emplumée au milieu de cette
partie.—Brrt. et SroizM.

1 En Argentina peut-étre les deux espéces de Theristicus se rencontreront, l'une
venant du sud, l’autre du nord. M. Hudson dit que le Theristicus apparait
en mai et devient plus rare au nord de Buenos Aires. I] faudra done bien
examiner les Theristicus d’Argentina ayant de pouvoir fixer la distribution
géographique des deux espéces.

similis, sed multo minor, magnitudine fere galling, que vocatur matutui”). I
est done éyident que cette espece de Marcgrave restera toujours douteuse. Peut-
étre que loiseau en question était un vrai Numenius.

I] parait que deux espéces de Trochilidées mentionnées par M. le
Dr. L. Taczanowski comme provenantes des environs de Lima, ot
elles seraient recueillies par M. Constantin Jelski*, ne sont pas des
habitants de cette contrée, savoir :—

Phaéthornis malaris (Licht.) et
Campylopterus largipennis (Bodd.).

Grace 4 la bonté de feu Dr. Taczanowski, Berlepsch a eu l’occasion
d’examiner les deux oiseaux en question appartenants au Musée de
Varsovie. Ce sont des individues montées qui ne portent plus
d’étiquettes originales du collecteur, et Berlepsch ne doute pas qu’en
vérité elles sont provenues des collections faites par Jelski a Cay-
enne, et non de Lima! Dans une lettre de M. Taczanowski a
Berlepsch le premier a concédé que indication d’habitat, “ Lima,”
pour ces deux espéces était donnée par méprise, mais il persistait
que les individues en question seraient venues du Pérou, probable-
inent du Pérou central. Berlepsch insiste sur son opinion qu’elles
seraient venues de Cayenne, car autrement nous aurions l’espéce
amazonine Campylopterus obscurus, Gould, tandis que l’oiseau en
question du Musée de Varsovie s’accorde tout-a-fait avec le C. largi-
pennis typique de Cayenne *.

1 Cf. Gigl. et Salvad. Ibis, 1869, pp. 63, 64.

2 Tacz. P. Z. 8. 1874, p. 541.

’ Stolzmann esi de l’avis qu'il serait presque absolument impossible que le
Phaéthornis superciliosus envoyé par M. Jelski provenait des environs de Lima.
Tous les Colibris appartenant au genre Phaéthornis sont propres aux foréts
humides. Ilya uneseule exception de cette régle, formée par le Ph. griseigularis,
Gould. Mais méme cette espéce se tient dans les vallées chaudes de la Sierra, ou
la végétation est assez riche et ot il ya ga et la des fourrés trés épais. Aux
environs de Lima cependant la végétation est extrémement pauvre, et par con-
séquent ne présente pas des conditions fayorables pour les espéces du genre
Phaéthornis. On peut supposer que M. Jelski, en partant de Cayenne pour le
Pérou, a pris avec soi quelques peaux de ce pays qu'il a ajouté 4 son premier
envoi péruvien qui proyenait des environs de Lima. Peut-étre il a oublié de les
pourvoir des étiquettes, ce qui a induit enerreur le Dr. Taczanowski. La méme
remarque s'appliquerait au Campylopterus largipennis (Bodd.).

402 MM. H. VON BERLEPSCH AND J.STOLZMANN- [May !7,

Quoiqu’il serait trés probable que notre connaissance de la faune
ornithologique des environs de Lima ne sera pas encore tout-i-fait
parfaite, on voit bien que cette contrée n'est pas riche en espcces
d’oiseaux.

On ne devrait pas y ajouter les espéces trouvées dans les vallées
de la pente occidentale des Andes au-dessus de Lima. La faune de
cette contrée sera probablement plus riche, mais jusqu’a présent elle
est trés peu connue. Autant que nous savons, elle est tout-a-fait
différente de celle de la cote. M. le Prof. Nation 4 Lima a recu
une petite collection faite dans les vallées élevées 4 la source du
fleave Rimac (hauteur 8000 414,000 pieds), qui contenait les espéces
suivantes, qui ne se trouvent pas dans la région de la edte, comme :—

1. Buarremon nationi, Scl.

(= Pipilo mystacalis, Tacz.).
Catamenia inornata ( Latr.).
Pseudochloris lutea (Lafr. et D’Orb.).
Hemophila pulchra, Scl.

Phrygilus gayi punensis, Ridgw.
Phrygilus fruticeti (Kittl.).

Diucea speculifera (Latr. et D’Orb.).
Ochthoéca leucometopa, Scl. et Salv.
Leptasthenura pileata, Scl.

10. Chalcostigma olivaceum (Lawr.).

11. Metallura opaca (‘Tsch.).

12. Polyonymus caroli (Bonap.).

13. Colaptes puna, Cab.

14. Bolborhynchus andicola (Finsch) *.

BGO $1 Sa Sr eee BS

Peut-étre on y pourrait ajouter d’autres mentionnées par Tschudi
de la pente occidentale des Andes péruviennes.

iv. Considérations générales sur la Faune ornithologique des
environs de Lima.

Des 153 espéces mentionnées de cette coutrée il y a du moins 31
qui ne s’y trouvent que de passage en hiver, venant de l’Amérique
du nord, ot elles nichent. Les autres 122 espéces probablement
nichent daus la région de la céte du Pérou, mais on ne peut pas
étre sir dans tous les cas, surtout en regard des viseaux maritimes,
qui quelquefois vaguent trés loin de leur pays natal. Néanmoins, de
ces 122 espéces il y aad peu prés 95 espéces terrestres, dont nous
proposons d’expliquer les relations géographiques.

1. Il y a9 de ces 95 espéces terrestres (ou plus de 9 pour-cent)

1 Tl faudra encore ajouter a cette liste une espéce recueillie par Jelski 4 Obra-
jillo, qui est une vallée voisine de la vallée du Rimac (pente occidentale), 4
savoir: Synallaxis pudibunda, Scl. En outre M. le docteur Sclater nous a
autorisé d’annoncer qu’il vient de recevoir par le Prof. Nation un exemplaire
de |’ Attagis gayi, Geoffr. et Less., tué dans les Andes au-dessus de Lima.—Brrt.
et Srouem,

1892.] ON BIRDS FROM PERU. 403

qui paraissent exclusivement propres 4 la région de la céte des
environs de Lima et d’Ica :—

Mimus longicaudatus’. Amazilia amazilia.
Petrochelidon ruficollaris. Chrysoptilus atricollis.
Dives kalinowskii. Porzana erythrops.
?Cinclodes taczanowskii*. Fuligula nationi.

Geositta crassirostris.

A la céte péruvienne plus au nord, dans le voisinage de Tumbez et
de Chepen, quelques de ces espéces sont représentées par des espéces
voisines :—

Mimus longicaudatus par Mimus espéce inédite ;
Amazilia amazilia par A. leucophea, Reichb.' ;
Dives kalinowskii par D. warszewiczi, Cab. ;
aussi Chrysomitris capitalis par Ch. siemiradzkii.

I] n’y a que deux espéces (des buit nommées plus haut) qui parais-
sent d’étre représentées dans la partie méridionale de la céte par des
formes voisines, savoir :—

Cinelodes taczanowskii par C. nigrofumosus, Lafr. et D’Orb. ?

Catamenia analoides par une forme plus grande (C. analis, Lafr.
et D’Orb.?).

Dans la vallée du Rio Chota, systéme du Marajfion, aux environs de
Callacate (et Cutervo), le Chrysoptilus atricollis est représenté par
une forme voisine: Ch. peruvianus, Reichb., qui habite aussi les
environs de Chachapayas. ;

2. Il y a4 espéces qui sont conjointement propres 3 la faune de
Lima (et d’Ica) et celle de Tumbez (et Chepen) :-—

Geothlypis auricularis.

Saltator immaculatus. Lima et Chepen.
Poospiza bonapartei.

Geositta peruviana. Lima et Pacasmayo.

Néanmoins la faune de Tumbez présente beaucoup de différences,
possédant a peu prés 7 espéces qui lui sont propres, et A peu prés

Stolzmann pense que le Mimus de Tumbez sera identique avec celui de
Guayaquil, mais nous n’ayons pas encore eu l’opportunité de comparer des
oiseaux de cette localité.—Brrt. et Srouz.

* Cette espéce se trouvera peut-étre aussi dans les environs d’Islay, dans la
partie méridionale de la cote du Pérou. En méme temps il est probable
qu'elle habitera aussi les régions au nord de Lima, car dans la baie de Chimbote
Stolzmann a yu plusieurs fois un Cinclodes qui lui a paru identique avec le
C. taczanowskii.—Beru. et SrouzM.

® Le type de 1’4. leucophza, Reichb., est dit d’étre recueilli au volcan
d’Arequipa par Warszewicz, mais ce serait probablement une erreur, ou l’espéce
de Tumbez (aussi de Pacasmayo et de Callacate) sera distincte. Selon l’expé-
rience de Stolzmann il est peu probable que le type d’ Amazilia leucophea yenait
d’Arequipa, car les espéces du genre Amazilia alliées 4 VA. amazilia dans leur
distribution verticale ne dépassent pas la hauteur de 5000 pieds (acette hauteur
VA. leucophea a été trouvée par Stolzmann 4 Callacate), tandis que la ville
d’ Arequipa est située 4 7845' au-dessus du niveau de la mer, et le volcan Misti
est encore plus éleyé.—-Burt. et Svouzu.

404 MM. H. VON BERLEPSCH AND J. STOLZMANN [May 17,

35 espéces qui sont conjointement propres 4 cette faune et celle de
Guayaquil (de |’ Ecuadeur occidental)’.
3. Il y aura 5 espéces qui sont conjointement propres a la faune
de Lima, de Tumbez, et de Guayaquil :—
Campylorhynchus balteatus. ?Ornithion imberbe sclateri.
Dendroica aureola peruviana. Hapalocercus fulviceps.
Neorhynchus nasesus”.

Les deux dernitres espéces se trouvent aussi dans les environs de
Callacate (vallée du Rio Chota), tandis que le C. balteatus y est repré-
senté par l’espéce voisine C. fasciatus, Sws.

4. Stolzmann a déji démontré® que la faune des environs de
Callacate et de Cutervo, dans la vallée du Rio Chota (syst¢me du
Marafion) entre les deux chaines occidentales des Andes, poss¢de
quelques espéces qui autrement paraissent tout-a-fait propres ala
faune de la céte. C’est une chose remarquable parce que la hauteur
de ces localités est d’& peu prés 5000 pieds. Outre les deux espéces
que nous venons de nommer (Ornithion imberbe sclateri et Hapa-
locercus fulviceps) cette particularité est illustrée par trois espéces
qui habitent les environs de Lima :—

Sporophila simplex ;
Molothrus occidentalis ;
Bolborhynchus aurifrons :

dont la premiére n’est trouvée qu’a Lima, Nancho, et Callacate,
la deuxiéme qu’A Lima, Tumbez, et Callacate (et Cutervo), et
la troisiéme qu’ Lima et a Callacate. La derniére espéce est
aussi mentionnée de Titicaca (‘I'acz. Orn. du Pérou, p. 211), mais
cette indication de M. Raimondi manque encore de confirmation.

5. Quant 4 la partie méridionale de la cote, il y a 8 espéces qui
sont conjointement propres 2 la faune de Lima (et d’Ica) et celle
d’Islay (Pérou du sud) jusqu’a Tacna et Tarapacd (Chile du nord,
ancien territoire péruvien et bolivien) :—

Jusqu’a
Anthus peruvianus...........-++- Islay.
Conirostrum cinereum*.......... Tarapaca.
Xenospingus concolor............ Tarapaca.
Aneretes reguloides .......-.... Tacna.
Pyrocephalus obscurus .......... Islay.
Geositta maritima .............. Cobia.
Rhodopis vespera ..........- o, 2 0 Mi denn.
Chordeiles acutipennis pruinosus .. Tambo.

Autant que nous savons, il n’y a aucune espéce propre a cette
faune de la céte méridionale qui ne se trouve également dans les
environs de Lima, sauf quelques formes purement chiliennes qui ne
se répandent pas si loin au nord, comme Agriornis maritima,

1 Of. Berl. P. Z.S8. 1885, p. 122.

2 Le Neorhynchus de Tumbez est beaucoup plus petit que celui de Lima, et
appartiendra probablement 4 une sous-espéce distincte.

3 Voyez Tacz. Orn. du Pérou, i. p. 42 ff.

+ D'Orbigny dit qu'il a trouvé cette espéce aussi & Inquisivi, Prov, Sicasica
(Bolivie orientale), mais ce sera peut-étre une erreur. —Buru. et STOLZM.

1892.] ON BIRDS FROM PERU. 405

Ageleus thilius, Geositta cunicularia, Leptasthenura egithaloides,
Synallaxis modesta, et d’autres dont plusieurs seront peut-étre
limitées aux régions élevées de la pente occidentale des Andes.
6. Deux espéces paraissent conjointement propres & la faune de
Chepen (Pacasmayo), de Lima et d’Islay (vallée de Tambo) :—
Myjiobius rufescens ;
Thaumastura cora.
7. Une espéce se répand sur toute la céte péruvienne de Tumbez
jusqu’a la vallée du Rio Tambo :—

CEdicnemus superciliaris.

8. Les espéces suivantes se répandent de la céte de l’Ecuadeur
(Guayaquil) jusqu’’ la cote du Pérou méridional ou du Chile sep-
tentrional (Tacna, ete.) :—

Sporophila telasco. Jusqu’d la vallée de Tambo.
Muscigralla brevicauda. Jusqu’d Tacna.
Pyrocephalus rubineus heterurus. Jusqu’d Tacna et Arica,

9. Une espéce se répand de Lima jusqu’au Chile central
(Santiago) :—
Chrysomitris uropygialis.
10. Une autre espéce se trouve dans toute la région de la céte
du Pérou de Tum bez jusqu’au Chile central :-—

Melopelia meloda.

11. Les suivantes habitent la région de la cote péruvienne de
Lima au nord jusqu’au Chile et la Patagonie. | Quelques-unes
habitent méme une partie de l’Argentina, et d'autres se trouvent
encore dans l’étroit Magellan :—

Muscisaxicola mentalis. Jusqu’d la Patagonie.

Elainea albiceps modesta. Jusqu’d la Patagonie et l Argen-
tina oce.

Thinocorus rumicivorus. De Pacasmayo A la Patagonie et
YArgentina.

Theristicus melanopis. Jusqu’d l’étroit Magellan.

Falco cassini. Jusqu’d Vétroit Magellan.

12. Les espéces qui suivent sont connues de toute la céte péru-
vienne, commengant de la vallée du Rio Tambo au sud, et en méme
temps se répandent le long de la céte de ’Ecuadeur et de la Colombie
occidentale jusqu’’a l Amérique central et le Mexique :—

Ceryle americana cabanisi.
Crotophaga sulcirostris.

13. En tout il y aura 4 peu prés 44 espéces terrestres (des
95 nommeés plus haut), ou plus de 41 pour-cent, qui sont limitées &
la région de la cdte’ et ne se trouvent pas sur la pente orientale des

1 Probablement quelques-unes de ces espéces s’éleveront aussi dans les mon-
tagnes de la pente occidentale des Andes jusqu’a une certaine hauteur. Mal-
heureusement la faune de ces contrées est encore trés-peu connue. Néanmoins
nous savons que 5 espéces qu’on doit regarder comme des formes caractéris-
tiques de la cote se trouyent 4 Callacate et Cutervo 4 une hauteur de 5000!
etc.—Burt, et Stouzm.

406 MM. H. VON BERLEPSCH AND J.STOLZMANN [May 17,

Andes. Nous y avons compris les cing espéces qui sont constatées
@habiter aussi la région de Chota (a Vorient de la chaine la plus
occidentale des Andes de Ja latitude de Pacasmayo) parce que la
faune de cette contrée a une certaine ressemblance avec celle de la
cote.

De ces 44 espéces il n’y a qu’a peu prés 10 qui peut-étre seraient
représentées dans l’orient ou au plateau des Andes par des formes
voisines :—

Geothlypis auricularis par G. velata?

Molothrus occidentalis par ?

Cyanotis rubrigastra par C. sp. nov.‘ (de Junin).

Ornithion imberbe sclateri par O. imberbe?

Pyrocephalus rubineus heterurus par P. rubineus.

Geositta peruviana par G. frobenr?

Chrysoptilus atricollis par Ch. peruvianus. De Chota et
Chachapoyas.

Ceryle americana cabanisi par C. americana.

Crotophaga sulcirostris par C. ani.

Chordeiles acutipennis pruinosus par Ch. acutipennis.

Les autres 34 espéces terrestres de la région de la céte ne sont
pas représentées par des espéces ou formes voisines dans la région
de lorient du Pérou.

A ces 44 espéces terrestres nommées plus haut on pourrait ajouter
a peu prés 25 espéces maritimes qui certainement ne se trouveront
pas dans la région orientale. Ce fera 69 de 122 espéces qui pro-
bablement nichent dans la région de la céte et qui manquent &
Yorient—ou plus de 56 pour-cent. Peut-étre quelques-unes des
espéces de passage aussi ne se trouveront pas dans l’orient du Pérou,
comme Hirundo tytleri, Dolichonyx oryzivorus, Ardetta ewilis, Are-
naria interpres, Aigialitis semipalmata, 42. nivosa, Calidris arenaria,
Tringa minutilla, Phalaropus lobatus, Porzana jamaicensis, Sterna
elegans, Larus franklini, Xema sabinei. Alors il y aura 82 espéces
de 153 mentionnées des environs de Lima et d’Ica qui ne se trouve-
raient pas dans Vorient du Pérou, ou 4 peu prés 54 pour-cent.

14. Quant 4 les espéces qui se trouvent en méme temps dans les
environs de Lima (et d’Ica) et dans lorient du Pérou, il y a 4 peu
prés 4 espéces qui paraissent conjointement propres & l’occident et
a Porient du Pérou, mais il y a de doute sur quelques-unes de ces
espéces qui ne sont mentionnées de Lima que par le voyageur
Tschudi :—

Tridornis analis. Lima (Tschudi) *.
Pyranga testacea tschudii.

’ Ty a une forme distincte de Cyanotis 4 Junin que nous avons intention
de décrire prochainement.—Burt. et Sronzm.

* Selon l’expérience de Stolzmann les espéces du genre Jridornis sont pro-
pres aux foréts humides élevées et ne descendent pas au-dessous de 5000’.
Aussi ce genre parait absent complétement sur la pente occidentale des Cordil-
léres, car Jelski ne ’a pas trouvé 4 Paucal, ni Jelski et Stolazmann 4 Tambillo
ou Cutervo.

1892.] ON BIRDS FROM PERU. 407

Stenopsis decussata.
Conurus frontatus. Lima (Tschudi).

15. Quelques espéces de la faune de Lima ne se trouvent pas dans
la région orientale du Pérou de la méme latitude, mais dans
des contrées de l’orient plus septentrionales, 4 Chachapoyas, ete. :—

Pheucticus chrysogaster.
Trupialis bellicosa.
Myrtis fannye.

Ces espéces traversent aussi les Andes en Ecuadeur, ot elles sont
trouvées & Riobamba, etc.

Turdus chiguanco.
Tanagra darwini.

Metriopelia melanoptera’.

18. Une forme habite les deux régions de la Colombie, de
lEcuadeur, et du Pérou :-—

Sycalis arvensis luteiventris.
19. Dans lonest et ’ orient del’ Ecuadeur et du Pérou se trouve :—
Chrysomitris capitalis.

20. Trois espéces se trouvent dans Vouest et dans Vorient du
Pérou et de la Bolivie :—

Phrygilus plebejus.
Micropus montivagus.
Gymnopelia erythrothorac.

21. Une espéce se répand sur toutes les régions andines de

A ces 23 espéces ou pourrait ajouter les 9 espéces qui paraissent
propres 4 la faune de Lima et les 3 espéces qui ne sont men-
tionnées de la céte occidentale que par Tschudi (Jridornis analis,
Tanagra cyanocephala, Conurus frontatus), ce que fera un total de

En étudiant l’avifaune de la céte du Pérou nous pouvons dis-
tinguer deux districts bien caractérisés au point de vue ornitho-

ces deux régions coincide plus ou moins avec la vallée Chicama

qui lui ressemblent sous le point de vue physiographique. En

couverte de rhizophores, et en conséquence présente un caractére
tout-a-fait différent, et la vallée du Zarumilla, formant une transition

2. On Lucioperca marina, C. & V.
By G. A. Boutencer.
[Received April 30, 1892.]

(Plate XXV.)

Thanks to the kindness of Drs. Strauch and Herzenstein, I have
been favoured with the loan of a specimen of the rare perch Lucio-
perca marina, C. & V. (Perea labraz, Pall. nec L.), of which very
few examples have been examined since its first description by
Pallas in 1811. The only recent author who has contributed
original notes on the subject is Kessler’, who showed that this fish
is distinguished from the Zander (Z. sandra) by fewer branched
dorsal rays, and that therefore Pallas’s statement “ 12 rays’’ was
not a misprint for 22, as suggested by Cuvier and Valenciennes.
The specimens examined by him have 16 or 17 rays; the St.
Petersburg specimen 17. Whether any have as few as 12 rays
remains to be ascertained by the inspection of a greater namber of
examples than have hitherto been available for study. The point to
which I now wish to draw special attention is the close affinity
which the Black-Sea and Caspian species bears to the North-
American, and especially to L. canadensis. Leaving aside the

hitherto little-understood LZ. marina, it will be found that the
Europzo-Asiatic and American species form two well-marked
groups: the former (L. sandra and L. volgensis), characterized by the
lesser space between the ventrals and the greater development of
the ventral and anal spines, is nearer related to Perca, with which
it is connected by L. volgensis, a fish almost as much a true Perch
as a Pike-Perch; the latter (L. canadensis and L. vitrea) charac-
terized by the wider separation of the ventrals and weaker ventral
and anal spines.

These two groups are so well marked that one might feel tempted
to treat them as distinct genera, were it uot for the information now
afforded by L. marina, which although agreeing in most respects
with the American L. canadensis, yet differs from it in the more
approximate ventrals, in this point resembling its European con-
geners, and thus forming a very interesting connecting group, as
may be seen from the following synopsis of the five species which
constitute the genus Lucioperca’.

' Lucioperca should date from the first edition of the ‘Régne Animal,’ 1817,
where Cuvier (p. 295) does use the Latin name (‘ce qui leur a fait donner le
nom de Jucioperca”), although indirectly and without a capital.

Lucioperca marina thus agrees in its scale- and fin-formula with
LL. canadensis, whilst in its compressed back and almost naked head
it agrees with LZ. vitrea. The following description is taken from
the specimen in the St. Petersburg Museum (No. 6205, Alexan-
drowsk, Caspian Sea).

Depth of body 43 times in total length, length of head 32 times ;
diameter of eye about } length of snout and 1 length of head, and
nearly equal to interorbital width; strongly enlarged, canine-like
teeth in jaws and palate; lateral preemaxillary teeth forming a single
series; maxillary reaching to below posterior fourth of eye, the
width of its distal extremity rather more than 3 diameter of eye;
head naked, except a few scales on the operculum ; opercular spine
feeble. Dorsal XIII, I 17; originating above axilla, the two por-
tions nearly equally deep, the spinous } longer than the soft, from
which it is separated by an interspace equal to } the diameter of
eye; first spine # length of second, 3 length of longest. Anal II
12; a little deeper than dorsals; spines very feeble and closely
attached to the soft rays. Pectorals 3 length of head. Ventrals
separated by an interspace equal to } the width of their base; spine
very feeble and closely attached to the soft rays. Middle caudal

rays # length of outer. Scales 115 3 L. 1. 79. Pyloric appen-
dages 5, the longest as long as the stomach, the shortest only half
as long. Brown above (in spirit), whitish beneath; ten dark
vertical bars on the sides ; first dorsal blackish, second with a blackish
bar along the middle.

Total length 280 millim. *

3. On the Antelopes of the Genus Cephalolophus.
By Oxprietp Tuomas, F.Z.S.

[Received April 30, 1892.]

The genus Cephalolophus has long stood in need of a general
revision, and I am enabled to undertake such a work owing to
the fact thet the types of a very large number of the described
species, valid and invalid, are in the collection of the British Museum.
These types have all been carefully examined and compared, and,
whatever its other shortcomings may be, it is hoped that the present
paper will at least be of service to zoologists by clearing up some of
the many doubtful questions of which the solution depends on these
typical specimens.

It has not been thought necessary to give full synonymies of the
species, these being fully given in Gray’s numerous papers on the

1 The total length of a Percoid fish should be given to the extremity of the
middle caudal rays. In describing the proportions, it is of course necessary to
exclude the caudal fin altogether, as we exclude the vertical fins in measuring the
depth of the body.

subject. In the same author’s ‘ Knowsley Menagerie’ figures of
the majority of the species will also be found.

The genus Cephalolophus is a remarkably uniform one, the
species, while widely differing in size, colour, and other superficial
characters, agreeing exceedingly closely with one another iu all the
more essential features. I have therefore no hesitation in placing
them all under one single generic heading, with the synonymy as
follows :—

Of this genus 18 species appear to deserve recognition, and of

A. Horns, when present, pointed directly backwards, in a

generally present in female. Hars moderate or short,
rounded, their length much less than the distance from

mm.; basal length of skull more than 240.

able to determine with certainty :—

Hab. Senegal.
The general appearance of this animal is more that of a Gazelle than a
' Cephalolophus, but the “ narrow dark streak, not open but naked, between
the eye and the nose” would seem to show that it is a member of the
present genus. Its remarkable character of tufts on all the four limbs is
rendered less improbable by the recent discovery of the heel-tufts in C. dorie
(infra, p. 424).
(2) Cephalolophus ruficrista, Bocage, P. Z. S. 1878, p. 744.
Hai. W. Africa; probably Angola.
Only known from the head, which is like in general appearance to that of
C, niger, but is decidedly larger.

their length much less than the distance from eye to muzzle. Fur
very short on the fore-quarters, longer on the hind back, but in
adults worn off and showing the whitish underfur or naked skin

very much to excuse Dr. Gray in his supposition that the young
*< melanoprymnus’”’ represented a different species.

The occurrence of C. sylvicultor on the Gaboon, as evidenced by
the identification of C. melanoprymnus with it, is here of importance
as confirming my allocation of ‘“ C. longiceps,’”’ also from the Gaboon,
to its synonymy. ‘The typical skull of the latter agrees in every
respect with a Fantee skull of C. sylvicultor, although it is, as Gray
said, somewhat slenderer in the nasal region than the only skull
which he then had for comparison with it.

2. CEPHALOLOPHUS JENTINKI, Sp. n.

Size large, though smaller than C. sylvicultor ; form stout. Ears
short, broad and rounded. Colour of head, ears, neck all round
as far back as the withers, throat, and a narrow sternal line deep
uniform black ; of body above and below coarsely grizzled grey, the
hairs ringed with black and white. Lips and chin, a line all round
the fore-quarters separating the black from the grey, axillew, groins,
fore and hind legs whitish; a rather darker mark running across
the outer side of the forearm.

Horns long, tapering, placed in the line of the nasal profile,
divergent as in C. sylvicultor :—

@. 155 mm. long, base not specially thickened, basal diameter
going about 54 times in the length.

Skull much longer in proportion to the size of the animal than in
C. sylvicultor, agreeing, in fact, precisely in size with that of the
larger species. In other respects also it agrees so closely with that
of C. sylvicultor, that had the external characters not been known
the two species would have been hardly supposed to be different.
Such as they are, however, the following are the differences that I
am able to find between the two skulls. The frontal outline is
flatter, and the horn-cores are perfectly straight, not bowed down-
wards terminally ; the facial region above the tooth-row and below
the anteorbital fossa is markedly swollen out laterally, so that the
teeth and their alveoli for a vertical height of nearly an inch are quite
hidden in an upper view of the skull; the outer edges of the infra-
orbital foramen are rounded instead of being sharp; the three
posterior notches in the palate, approximately equal in breadth in
sylvicultor are very unequal in jentinki, as the lateral ones are
broad, shallow, and open, while the mesial one, and with it the
whole posterior nares, is markedly narrower; the bulle have, just
behind the articulation of the stylohyal, a very marked secondary
inflation, projecting outwards and forwards and cutting off the ex-
tension backwards of the bony lamina external to the articulation ;
this extra swelling is quite absent in C. sylvicultor. In all these
characters, slight as they seem to be, the five skulls of C. sylvicultor,
including the type of C. longiceps, agree absolutely with each other,
and differ from the single skull before me of C. jentinki.

Dimensions.— 2. Height at withers 770; ear 105; hind foot

Hab. Liberia (Ff. X. Stamp/fii).

This fine species, discovered in Liberia by Dr. F. X. Stampfli,
from whom, through Dr. Biittikofer, the Museum obtained the
specimen above described, was referred’ by Dr. F. A. Jentink, of the
Leyden Museum, to Gray’s C. longiceps. This reference, in my
opinion, was most wise and prudent under the circumstances, not
only on account of the extraordinarily close resemblance of its skull
to that of C. longiceps, the only part of the latter form known, but
also because there was at that time no evidence that C. sylvicultor,
to which I refer C. longiceps, inhabited the Gaboon, whence came
the latter animal. Now, however, that the reference of C. melano-
prymnus to C. sylvicultor shows that the latter form does inhabit
that district, the true owner of the typical skull of C. longiceps,
practically identical as it is with that of C. sylvicultor, becomes at
once evident. It is therefore clear that the Liberian species, so
different from C. sylvicultor externally, but so like cranially, requires
a new name, and I think no better name can be given it than that
of my friend Dr. Jentink himself, whose valuable papers on the
Liberian mammals are characterized by a carefulness above all
praise, and whose very carefulness, led astray by Dr. Gray’s more
serious mistakes, caused him to make the venial error in the determi-
nation above referred to. In fact, it could scarcely be called an
error at all, for at that time it would have been quite unjustifiable
for him to have described the Liberian form as new, in face of the
extraordinary resemblance of its skull to that figured by Dr. Gray
as C. longiceps.

of which I have as yet seen no specimen. It is evidently allied
to C. natalensis, but may readily be distinguished by its much
greater size.

4. CEPHALOLOPHUS NATALENSIS, Sm.

Cephalophus natalensis, A. Smith, 8. Afr. Q. J. i. p. 113 (1834).

all over, without marks or stripes of any kind, except that there is
a faintly marked red superciliary line. Back of neck greyish brown.
Chin and throat whitish. Tail slender, rufous at base; brown,
tipped with white, at its extremity.

Horns set parallel to nasal profile :—

6. Short, conical, much thickened at their bases ; their greatest
basal diameter going about 23 times into their length; length about
70 mm. in an old specimen.

Q@. Similar to male, but smaller, slenderer, and more sharply
pointed. 37 mm. in length.

Skull: frontal region markedly roughened and convex: ante-
orbital fossz of medium depth, their bottoms 14 mm. in a male, 12
in a female, distinct from one another; edge of median posterior
palatal notch but little anterior (3 or 4 mm.) to the lateral notches.

Cephalophus aureus, Gray, Aun. Mag. N. H. (4) xii. p. 42
(1873).

Size medium. Colour of body rich chestnut, scarcely or not at
all paler below. Centre of face and crest deep black, contrasting
markedly with the rufous superciliary streaks. Nape browner.
Feet and tip of tail blackish, a few white hairs in the terminal tuft
of the latter. Hoofs apparently longer in proportion than usual ;
lower edge of the posterior outer one 40 mm. in length.

Horns, judging enly from the cores, decidedly short, and but
little expanded at their base ; the cores in an adult male about 48
mm. long. Their set parallel to, and a little below, the level of the
nasal profile.

Skull with the frontal region decidedly convex. Muzzle rather
narrow and elongated. Anteorbital fosse of medium depth, their
bottoms about 16 mm. from each other. Median posterior palatine
notch some distance (7 mm. in type) in front of the level of the
lateral notches.

Dimensions.— 3. Approximate height at withers 500 ; ear 60 ;

420 MR. O. THOMAS ON THE ANTELOPES [May 17,

Skull—basal length 160; greatest breadth 80 ; orbit to gnathion
91°5; nasals, length 69, greatest breadth 34; muzzle 61; upper
molar series 50.

Hab. Cameroons [ Buchholz, fide Peters]. Gaboon [Du Chaillu
(Brit. Mus.)].

The type of Gray’s C. awreus, which I refer with some doubt to
this species, is a young animal, and the differences in coloration
are probably due to this cause. Its body is far brighter and more
fulvous than that of the adult, the withers and shoulders are browner,
and the caudal tuft is more abundantly mixed with white.

6. CEPHALOLOPHUS LEUCOGASTER, Gray.

Cephalophus leucogaster, Gray, Ann. Mag. N. H. (4) xii.
p. 43 (1873).

Size medium. General colour dull chestnut-rufous, with a black
dorsal band. Face rufous, darker down the centre; crest mixed
rufous and black. Nape browner. Dorsal stripe commencing in
front of the withers, not pure black, but grizzled with rufous, and
not at all sharply defined laterally. Posteriorly, however, on the
tail it becomes abruptly very narrow and sharply defined, not
covering the whole breadth of the tail, but bordered on each side
with rufous or white. End of tail with a large mixed black and
white tuft. Under surface of body from chin to anus, inner sides
of forearms and hips, and also a line passing down the anterior side
of the metatarsi, whitish or pure white; no trace of a darker
sternal patch. Posterior faces of buttocks also pure white, very
different from the deep chestnut of this part in C. dorsalis.

Horns of type (apparently Q) conical, sharply pointed.

Skull, so far as can be gathered from a young and very imperfect
example, with a slender narrow muzzle like that of C. dorsalis
castaneus, quite unlike the short conical one of C. d. typicus.

Dimensions of the type, an immature specimen with the milk-
premolars still in position, and m* still below the bone :—Height
at withers 400; ear 65; hind foot 203.

Size medium. Ears extremely short and broad. General colour
bright chestnut-rufous, with a dark mesial stripe running from the
nose to the tail, only interrupted at the crest, which is sometimes
rufous. Centre line of face brown; superciliary streaks bright
rufous. Crest variable, either black, mixed black and rufous, or
wholly rufous. Dorsal stripe becoming absolutely black on the

back, sometimes sharply defined throughout, sometimes broadening
out on the withers into an ill-defined band passing down the
shoulders towards the fore legs. Under surface, inner sides of
limbs, and back of hams rufous like the sides; a black or blackish
longitudinal patch present in the sternal region. Fore limbs brown,
from the shoulder downwards, hind limbs from just above the heel.
Tail black above throughout, the black covering nearly the whole
breadth of the tail ; white below terminally.

Horns placed about in the same straight line as the nasal profile :—

gd. About 70 mm. long, slender, tapering, not thickened or
roughened basally, the basal diameter going nearly five times in
the length.

Skull with a remarkably short conical muzzle, the distance from
the anterior rim of the orbit to the gnathion less than the zygomatic
breadth. Anteorbital fossee of medium depth, their bottoms 19 mm.
distant from one another in a not fully mature female. Mesial
notch of palate about 4 or 5 mm. in advance of the lateral ones.
Bulle. with a small supplementary inflation, something like that dis-
tinguishing C. jentinki from C. sylvicultor.

Dimensions.— 2 (not fully adult). Height at withers 370; ear
47x44; hind foot 170.

Skull—basal length (c.) 143; greatest breadth 81; orbit to

6. CEPHALOLOPHUS DORSALIS CASTANEUS, subsp. n.

Rather larger than var. typicus, and ears apparently rather larger.
Colour deep chestnut all over, the dorsal line deep black, the meta-
carpals and metatarsals brown. Superciliary stripe chestnut,
indistinct, far less bright than in var. typicus, and the general
colour of the head darker and duller.

Skull with the muzzle of the ordinary slender elongate shape, the
distance from the anterior edge of the orbit to the gnathion ex-
ceeding the zygomatic breadth. Bulle with scarcely a trace of the
extra inflation behind the base of the stylohyal.

Teeth decidedly larger than in the typical form, the combined
lengths of the three milk-premolars 30°3 as against 25°5 in a
similarly aged example of C. d. typicus.

Dimensions of the type, an immature female.—Height at withers
485 ; ear 60; hind foot 205 ; tip of muzzle to eye 106.

Skull—basal length (c.) 159; greatest breadth 83; orbit to

* Hand-l, Rum. p. 94 (1873).

422 MR. O. THOMAS ON THE ANTELOPES [May 17,

“‘Cephalophus badius, 418 ¢”; and its skull was figured by him
under that name’. As, fortunately, the types of his C. badius and
breviceps are both still in the Museum, I am able to state that it
belongs certainly to neither of them, but its proper determination has
caused me much perplexity. On the one hand, its skull, so far as
one may judge from a single immature specimen, is so different from
similarly aged specimens of C. dorsalis as apparently to demand full
specific distinction ; while, on the other hand, it is externally almost
precisely identical. For the present, therefore, I take a middle course,
and make it into a subspecies, trusting that further specimens from
different localities will clear up the precise relationship it bears to the
true C. dorsalis, and also to its close ally C. leucogaster.

8. CEPHALOLOPHUS OGILByI, Waterh.

Antilope ogilbyi, Waterh. P. Z. S. 1838, p. 60.

Size medium. General colour bright orange, becoming rather
more rufous on the hind-quarters. Nose brown, but otherwise the
face is of the same colour as the body. Nape and sides of neck
brown or blackish, but the hairs here so thin and short that the
skin shows through and the general colour is but little affected.
Hinder back with a marked black central dorsal streak, commencing
vaguely at the withers, becoming narrower and more sharply defined
posteriorly, and running on to the tail. Limbs dull yellowish,
except on the phalanges, where they are brown or black.

Horns in the direct line of the nasal profile :—

3. About four inches long (109 mm.), conical, slightly incurved,
much broadened basally, their greatest basal diameter going 25 or
3 times in their length. ;

@. About a inch and a half in length, conical, smooth, broad at
base, pointed terminally, their length not twice their basal diameter.

Skull with a very considerable convexity in the frontal region.
Anteorbital fossze shallow, their bottoms 23 mm. distant from one
another in a male, 19 in a female. Posterior palate with the three
notches, median and two lateral, all at about the same level.

]0. CEPHALOLOPHUS RUFILATUS, Gray, Ann. Mag. N. H. (1)
xviii. p. 166 (1846).

Size small; form slender. General colour partly bright yellowish
rufous, and partly a peculiar bluish grey, the former colour covering
the sides of the face, the whole of the neck, the shoulders, flanks,
rump, and belly, while the latter prevails on the middle line of the
nose, on the forehead, occiput, back of ears, centre of back from
withers to rump, and all four limbs, from the elbows and middles
of lower legs downwards. Crest long, blackish. Tail rufous above
basally, black terminally.

Horns placed in the same line as the nasal profile :—

3. Short, conical, pointed (but no adult wild specimen available
for description).

. Rudimentary, mere low rounded knobs, hardly projecting
above the skin of the head.

Skull with a long and slender muzzle. Anteorbital fossz re-
markably deep, more so than in any other species, their bottoms
within from 5 to 10 millim. of each other. Mesial palatal notch
some distance (5 to 7 mm.) anterior to the lateral ones.

Dimensions — 3. Height at withers 360; ear 58; hind foot
179.

Skull (Q)—basal length 132; greatest breadth 66; orbit to

molar series 49.

Hab. W. Africa. Gambia [Whitfield (Brit. Mus.)|. A young
skull from the Niger [Buikie (Brit. Mus.)] has also, and probably
correctly, been referred to this species.

It is difficult to say to which of the other species this peculiar
little animal is most allied, especially as the absence of wild-killed
male specimens renders me unable to describe the fully developed

horns. It is perhaps a dwarf form of the dorsalis-group, with the
black replaced by grey, and the chestnut much lightened in tone.
Were there not, however, so many specimens known, all alike, one
might be forgiven for supposing it to be a hybrid between C. coro-
natus and C. marwelli, the former being responsible for the rufous,
and the latter for the grey in its generally piebald appearance.

the nasal region, which is blackish, Back from withers to rump
pale rufous, conspicuously banded transversely with deep shining
black. Under surface from chin to anus pale rufous, slightly paler
than the ground-colour between the bands. Limbs rufous, but
with broad black patches on the outer surfaces of the forearms and
lower legs, and with the phalanges black all round. Heels with
large glandular tufts of black hair on their postero-inferior surfaces.
Tail rufous, more or less mixed with black above, white below.

Horns in the same line as the nasal profile :—

¢. Short (barely two inches long), conical, tapering, sharply
pointed, their greatest basal diameter going about 24 times in their
length.

6. Short (less than one inch in an adult), smoother than in the
male, but otherwise similar in character.

Skull stoutly built. Nasal region broad, flat, parallel-sided.
Anteorbital fossee very shallow and little prominent, their bottoms
28 to 31 mm. distant from one another. Frontal region not spe-
cially swollen. Horn-cores so pressed downwards and backwards as
to cause marked depressions behind and below them on the parietals.
Palate with its three posterior notches about level.

Long only known from pieces of flat skin, this remarkable animal
has now been made thoroughly familiar to mammalogists through
the exertions of Dr. J. Biittikofer, who collected many specimens
of it, and of Dr. F. A. Jentink, who described them (Ul. ce.).
Although its plan of coloration, possession of heel-tufts, peculiar
parallel-sided skull, depressed horn-cores, and shallow anteorbital

of the limbs. Superciliary streaks whitish. Ears small, rounded,
behind dark brown. Rump and backs of the hams uniform with
body, except that just at the base of the tail on each side, and on
the top of the proximal half of the tail itself, the colour is rather
darker. Rest of tail above brown, beneath whitish ; limbs externally
like body.

Horns set up at a slight angle above the nasal profile, but not
nearly so much as in C. grimmii:—

3. Short (about 50 mm. long), thick at base; their greatest
basal diameter going about 23 times in their length.

426 MR. 0. THOMAS ON THE ANTELOPES [May 17,

Q. Entirely absent in the only specimen available (not fully
adult). No traces of horn-cores are to be seen on the skull, and
probably the female is always without them.

Skull broad and strong. Muzzle rather narrow. Anteorbital
fossze rather shallow, their bottoms about 14 mm. apart in an adult
male. Mesial notch of palate only about 4 or 5 mm. in advance of

Ti species shows a certain tendency to the peculiar coloration
of the rump characteristic of C. melanorheus ; the colour contrasts
of black and white of the latter, however, are only in its case dark
brown and light brown respectively.

The entire absence of the horns in the female is a very important
character, but merely on the evidence of a single specimen, and
that one not fully adult, I hesitate to give it definitely as one of the
characteristics of the species.

Similar in all respects to O. maawelli, except that it is rather
smaller, and that the brown colour of the back darkens to black on
and at each side of the base of the tail, below which there is an
abrupt change to white on the backs of the hams. Female with

wait until the opening up of the interior of Africa shows what are
the characters of any representative forms that may be found there.

Of this pretty species there are only in the Museum immature
and young specimens, and from this material I am unable to come
to a definite conclusion as to its relationship. In its general ap-
pearance, however, it has a certain amount of resemblance to the
Duiker group, of which it may be the West-African representative,
and | have therefore in the synopsis included it provisionally in the
same section as C’. grimmii and abyssinicus. I should, however, feel
no surprise if the examination of adult skulls and horns proves this
conclusion to be wrong.

about equal to the distance between the anterior canthus and the
rhinarium. Colour grizzled yellowish grey, with rufous face, brown
nasal mark, and brown feet, just as in the grizzled varieties of
C. grimmii, of which it is obviously the Abyssinian representative.

Horns (¢ ) set up at an angle above the line of the nasal profile,

This species is no doubt the Antilope madoqua of Riippell’, but
not the earlier described A. madoka of Hamilton Smith?, which is
Salt’s Antelope (Nanotragus saltianus, Blainv.). Both names are
_ founded on the native name Madoqua or Madoka assigned by
different authors to one or other of the two species, and probably
used indiscriminately for either.

Hamilton Smith’s name being happily antedated by De Blainville’s
“ A, saltiana,’ and Rippell’s incapable of adoption, as having been
used before, we are fortunately able to rescue both these beautiful
little species from the clutches of this barbarous and doubtful
native name.

of the species hitherto considered. Ears long, longer than the
distance from the anterior canthus to the tip of the nose, their tip
narrow and pointed. General colour of body pale greyish brown,
sometimes with a yellowish tinge, but very variable in tone ; more
or less grizzled, owing to the hairs being annulated with yellowish
and brown. Face rufous or yellowish, with a deep brown longitu-
dinal patch on the nasal region, rarely extending upwards to the
bases of the horns. Throat and belly like back. Chin, inner sides of
fore arms and of thighs, and underside of tail whitish or pure
white. Front of fore legs with a brownish line running down them
to the hoofs. Metapodials brown. Tail black above and white
below, but the base above is commonly coloured like the back.

Horns present only in g*. These set up at a considerable angle
to the line of the nasal profile; slender, tapering, their bases
roughened but not markedly thickened, their greatest basal diameter
going about 6 or 7 times in their length.

Skull long and narrow. Anteorbital fossee of medium depth,
their border above generally rounded, not sharply ridged; their
bottoms about 20 mm. apart in a fine male. Muzzle long, the
distance from the anterior edge of the orbit to the gnathion much
exceeding the greatest zygomatic breadth. Mesial notch of palate
extending some way in front of the lateral ones.

Dimensions.— 3. Height at withers 575; ear 110; hind foot 263.

Skull—basal length 183; greatest breadth 85; anterior rim of
orbit to gnathion 112; nasals, length 71, breadth 35; muzzle 64 ;
length of molar series 61.

Hab. Southern Africa, from the Cape northwards on the west to
Angola [Gabriel (Brit. Mus.) ; Anchieta (Lisb. Mus.)|, and on the
east to Taita [Wray (Brit. Mus.)] and Mount Kilima-njaro { Hunter
(Brit. Mus.) ].

This common and widely spread species has been made the basis
of a large number of untenable species, mostly without any really
valid excuse. Certainly the species is rather variable in coloration,
especially as to the tone of the general body-colour and the extent
of the dark patch on the face ; but the differences are all obviously
of little essential importance, and I have no hesitation in assigning
all the names above given to one single species.

C. grimmii and C. abyssinicus together form a little group some-
what apart from the other species, but I do not think this group,
to which Gray gave the name of Grimmia,is worthy of generic or
even of subgeneric rank. The character of the female being hornless,
on which some stress has been laid, is neither constant in C’. grimmii
nor non-existent in other species*, and the other characters are all
rather of degree than of kind, and all very difficult of definition.
Other species seem also to lead up towards the group, as for
example C. coronatus, which, when adult specimens are obtained,
may prove to be quite closely allied to C. abyssinicus.

1 Mr. Selous, however, says (P. Z.S. 1881, p. 763) “although the females are

almost always hornless, I have met with three examples bearing horns.”

430 PROF. F. J. BELL ON PONTASTER TENUISPINIS. [ May 17,

The Duikers appear to be inhabitants of open or merely brush-
covered regions, while the other Cephalolophi are for the most part
inhabitants of dense forest, as may be judged from their extreme
abundance in the West-African forest-region.

4. On the Characters and Variations of Pontaster tenuispinis.
By F. Jerrrey Bewt, M.A., Sec.R.M.S.

[Received May 2, 1892.]
(Plate XXVI.)

In the year 1846 Diiben and Koren published their invaluable
catalogue of the Echinoderms of Scandinavia, and since that time
the species which they called Astropecten tenuispinus has been
mentioned and more or less fully described by succeeding writers,
such as Sars, Liitken, Koren and Danielssen.

We know now that the specimens seen by the famous zoologists
who first described this species were all small examples ; two were
quite small, having R equal only to 12 or 18 millim., while the
third, with R equal to 45 millim., is much smaller than many speci-
mens now known to us.

The ratio of R to ris given by them as 4=1 ; but as r=9 millim., -
when R=45, it is clear that the proportion varies from 4 or 5 to 1.
The specimens described by Koren and Danielssen in 1884 were as
much as 260 millim. in spread, and R=130 and +=23; or the
proportion was as 57 (nearly) to 1.

With the variations in these proportions there must be some
variation in the relative size of the disc and the general appearance
of the specimen. Notwithstanding these differences, there has been
a consensus of opinion among Scandinavian naturalists as to what
should be called, as most of them call it, Archaster tenuispinus.
Thanks to the obliging kindness of Prof. Lovén and Dr. Danielssen,
I have been able to receive (and in most cases to keep for the
British Museum) various specimens from various localities. Prof.
Quennerstedt, of Lund, has been so kind as to compare specimens
which I sent him for examination with the example on which Diben
and Koren founded their species, not daring, rightly enough, to let
the valuable specimen under his charge run any risk through the

ost.
Having thus a considerable series of specimens before me, I find
that the range of variation of z® greater than we have yet sup-
posed, for + may be only 10 millim., and R=74 millim., or the
proportion instead of being 4 or 5 to 1 comes to be 72 to 1.

Mr. Sladen does not inform us what his ideas are as to Pontaster
tenuispinis ; but he obviously looks on it as a small species, for he

VARIATIONS OF PONTASTER TENUISPINIS .

1892.] PROF. F. J. BELL ON PONTASTER TENUISPINIS. 431

says of a variety that its “‘ habit” is much larger than that of “ any
examples which I have seen of the type-form.” The largest of his
varieties appear to have R=66, but Koren and Danielssen had
examples of P. tenuispinis in which R=130. However, it is
useless for anyone who has not, like myself, access to the collection
which Mr. Sladen describes, to hope to discuss with him any
question which is based on measurements, for of these no writer is
so chary.

The proportions of R to 7 in this variety of Mr. Sladen’s vary
from 37%, through 319 and 4 to 44, and 44; as the variability is so
great, [ consider the relation of R tov should be put aside as a
reason for distinguishing a variety of a form which itself shows a
variation between 4 and 72.

The original diagnosis of the species begins with the words “ radiis
attenuatis ”; but in this point I observe some differences among the
specimens, some of which have arms a good deal stouter than others.
But on this point it is necessary to be precise, for Mr. Sladen’s
variety, which he calls “ platynota’’' (a misprint, I presume, for

ani

platynotos), is said to be marked by a “rapid attenuation?’ of the
rays at a short distance above their base. If figures can be made
to prove anything, words may he taken to mean anything; and a
“rapid attenuation ” may mean anything between the loss of weight
which follows a few days’ hard exercise or the result of a ten-weeks’
bout of fever. When we bring this vague expression to the test of
measurement, we find that one example of the variety has an arm

432 PROF. F. J. BELL ON PONTASTER TENUISPINIS. [May 17,

15 millim. wide at its base, and 7 millim. wide midway between the
base and the tip, while an example of “ A. tenuispinus,” named by
the authorities of the Bergen Museum, gives with a base of 15 millim.,
a width at the middle of the arm of 5°5 millim., or °35 millim. more
than would keep the proportions of width of base to width at middle
equal in the two specimens.

A reference to the diagrams A and B (p. 431), in which the
proportions above given are plotted out, will show that in A the
‘€ attenuation ”’ is more marked than in B, but the difference is so
slight that I submit it is not of the least importance.

The original diagnosis goes on “‘margine alto’’; these words at
first presented some difficulty, as several of the specimens before me
are remarkable for their flatness; but the matter was quite cleared up
when I sent two specimens to Prof. Quennerstedt, in order to have
them compared with the type in the University of Lund.

These specimens, which I marked A and B, had respectively
R=76 and 51, while the depth of the body at the angles was 3°3
and 4°3 millim. each. In A the supero-marginals merely formed a
fringe to the upper surface of the arm, while in B they formed
a distinct line on the upper surface.

In Prof. Quennerstedt’s opinion A cannot be A. ¢enuzspinis, while
B is certainly very close to it. In other words, 4. tenuispinis, as
represented by its type, by the figure given by its describers, and by
the sketch sent me by the learned Professor of Lund, has the supero-
marginals “‘ forming a well-defined border on the abactinal surface.”
But this is the chief character by which P. limbatus, Sladen, is
distinguished from P. éenuispinus, Sladen (D. & K., sp.). As
a matter of fact, however, this is a point in which specimens brought
from the same locality vary very greatly, and every stage may be
found between that in which the supero-marginal is a mere line on
the upper surface, and that in which it forms a distinct band.

If, however, there are to be specific distinctions made, it is clear
that P. limbatus of Sladen must be regarded as the equivalent of
P. tenuispinis, D. & K.; and P. tenuispinus, Sladen, must receive
anew name. For this, however, I see no real need.

Recent observers have been struck by the presence at the base of
the arm, on the upper surface, of a perforated area, which it has
been proposed to call a ‘‘ papularium,” as the tubes which project
through the holes are “ papular” or respiratory tubes. At times
these “‘ papularia ”’ are so distinct that one wonders how it is that
they can have escaped the notice of earlier observers ; but the truth
is that sometimes the papularia are very indistinct, and at times they
cannot be seen at all. This is another very remarkable instance of
variation.

If the views which I hold are justly derived from the facts
which I have cited—facts, I may point out, which any worker
during the last ten years might have acquired for himself without
any overdue call upon his time—the synonymy of this species may
briefly be cited thus :—

The following diagnosis of this very variable form may be
offered :—

The proportion of R (greater diameter) to r (diameter of disc)
varies between 34 and 72. A very variable species in many
characters.

Dise and arms flat, but the depth of the side at the angles of the
dise varying somewhat; the arms taper regularly, and end in rather
fine points as arule. The bases of the arms on the dorsal surface
sometimes, but not always, marked by a perforated area (the papu-
larium) of an elongate lens-like form containing from ten to twenty
holes. The sides of the arms above bounded by a pretty stout
supero-marginal, which may, however, be so thin as to be merely
a line on the upper surface. There may be as many as 40
supero-marginals, and they pretty constantly each carry a well-
developed spine, the base of which is surrounded by a number of
spinelets. A similar, or sometimes rather stouter, spite is borne by
each inferomarginal, and one or more of the surrounding spinelets may
be prominent on account of their length. The intermediate plates
on the lower surface are, as a rule, thickly covered with spines, but
in these there are, at times, reductions. The spines on the ambu-
lacral plates vary considerably in number and disposition, but the
most usual arrangement appears to be a row of about six small
spines along the groove with one, two, or three larger spines set
transversely. Pedicellarize present or absent. Delicate spines may
sometimes be seen rising from the dorsal paxilliform plates.

5. A List of the Lycenide of the South Pacific Islands east
of the Solomon Group, with Descriptions of several
new Species. By Hamitron H. Drucez, F.E.S.

[Received May 3, 1892. ]
(Plate XXVII.)

In 1891 I published a list of the Lyczenidz of the Solomon
Islands in the ‘ Proceedings’ of the Society. The present paper is an
attempt to bring together the species of this family which have
been described as inhabiting the South Sea Islands to the east of the
Solomon Group. Our knowledge of the whole is, at present, very
small, as large numbers of important islands remain to be explored.
Mr. Butler published lists in the ‘ Proceedings’ of this Society for
1874 and 1875, and has since described a number of species, princi-
pally from the New Hebrides Islands. Out of 31 species here
enumerated, I have described 7 as new.

Several important genera, such as Catochrysops, Arhopala, and
Deudorix, seem to end their range quite on the western extremity of
the group.

Thanks to the kindness of Messrs. Godman and Salvin, I have
been able to examine their collection, which contains good series of
most of the species, which were obtained principally by Messrs. C.
M. Woodford and G. F. Mathew.

The types of the species described as new are in their collection.

The following table is intended to show at a glance the several

Three species of this genus occur in these islands: Z. /abradus
and Z. lulu, which are generally distributed, and Z. gaika, which I
have seen only from the New Hebrides.

I have carefully examined two specimens in the British Museum
which were received from the Godeffroy Museum—one of which, a
male, is labelled L. communis, the other, a female, L. alsudus—and I
am quite satisfied that, as pointed out by Mr. Butler (P. Z.S. 1875,
p. 616), they represent the same species, as does also L. phebe,
Murray. Lycena mangoensis, Butl., is nothing but a rather more
strongly marked form, and we have in our collection specimens from
Fiji Islands quite as typical L. a/sulus. Lycena caduca, Butl., again
is, in my opinion, a variety, as although I have, in the large series
before me, no specimen agreeing exactly with the type, there are
several very close to it.

Mr. Miskin has lately pointed out that /abradus is the oldest
name for this species (Ann. Queensland Museum, no. 1, p. 62,
1891), and is doubtless quite correct in so identifying it.

So far as I am able to ascertain, this insect does not occur east-
wards from the New Hebrides.

If I had not seen the specimen in the British Museum before
referred to, I should have considered Herrich-Schaffer’s description
of ZL. alsulus to have referred to this species, as he speaks of the
underside being without markings, save a few angular marks.

In the large series before me, I can detect no variation but the
absence or presence of the black anal-angular spot on the underside
of secondaries.

Mr. Mathew’s types are now in Messrs. Godman and Salvin’s
collection.

Taxicapa, Moore.

T. cleotas and T. excellens are distinguished at once from their
congeners 7’. nyseus, T. mindora, and 7’. arruana by having a dis-
tinct spot in the centre of the cell of the fore wing below, also by the
darker ground-colour of both wings. The genus has not yet been

1892. | THE LYCZNID& OF THE SOUTH PACIFIC. 437

recorded as occurring east of the New Hebrides Islands, and no
representative of it is found in Australia.

TALICADA EXCELLENS.

Scolitantides excellens, Butl. P. Z.S. 1875, p. 616, t. 67. f. 12’.

Mallicollo I., Pentecost I., New Hebrides (C. MZ. Woodford).
New Hebrides (Mathew). Erromango I., New Hebrides’.

Mr. Butler was evidently mistaken in describing his species as
differing from 7’. cleotas, Guér., by the male having the purple
colour spread over the primaries and the centre of the secondaries.
As a matter of fact 7. cleotas 3 has the purple of a lighter and
more brilliant hue, and much more extensively spread over both
wings, leaving the margins only narrowly black. Mr. Butler has
doubtless taken Guérin’s figure for a male, whereas it is a female with
somewhat more blue than usual. All females I have seen from
New Ireland have this blue to a greater or lesser extent, but I note
that females of 7. cleotas from the Solomon Islands are without it,
also all females of T. excellens.

I think 7. excellens can be distinguished by having the veins black,
and by the outer margin of primaries having a considerably broader
black border.

When I described this insect in 1887, examples stood in the
British Museum collection unnamed, as, although Mr. Butler
described it in 1883, the types were not incorporated and he had
forgotten that he had named it.

has several points of distinction.

NaCADUBA NOVE-HEBRIDENSIS, sp.u. (Plate XXVII. figs. 7, 8.)

Allied to JV. vitiensis, Butl.

d+ Upperside a somewhat lighter and more silvery shade of
violaceous blue. Underside pale ashen grey, with the markings,
which are arranged much as in J. vitiensis, less distinctly prominent,
and having on the margin of the hind wing one large black spot
only, which is placed between the two lower median nervules, and
which has its outer edge only bordered with metallic blue, and is
not encircled with bright yellow as in JV. vitiensis. A few blue
scales at the anal angle.

Q. Upperside much like that sex of NV. vitiensis, but the blue
area rather more extensive and considerably lighter in colour, and
having on the hind wing a marginal row of pale grey crescent-
shaped lunules. Underside as male.

A very short black tail on the lower median nervule, which is
occasionally tipped with white. There is very little trace of the
greenish scales at the base of the wings below.

Head, thorax, and abdomen concolorous with wings. Legs
greyish ; antennz brown, spotted with white.

Expanse as JV. vitiensis.

Pentecost I., Mallicollo I., New Hebrides (Woodford). Vaté L.,
New Hebrides (Mathew) (Mus. G. § S.). New Hebrides (B. M.).

A male from Vaté Island, obtained by Mr. Mathew, has the
black spot on the hind wing quite small; otherwise I notice no
variation in the good series before me.

This insect is distinguished at once from WV. vitiensis and also
from IV. samoensis by having a short linear tail.

NACADUBA FLORINDA. (Plate XXVII. fig. 12.)

Lampides florinda, Butl. Ann. & Mag. Nat. Hist. (4) xx. p. 354.

Lifu I., Loyalty Is. (B. M.). N. Australia (Mus. D.).

The type in the British Museum and a single specimen in our
own collection, which agrees exactly with it, are the only two I have

1892. ] THE LYCEZNID& OF THE SOUTH PACIFIC. 439

seen. Mr, Miskin does not refer to it, so that probably it is known
under another name in Australia.

NACADUBA MALLICOLLO, sp. n. (Plate XXVII. fig. 18.)

Lampides argentina, Butl. (nec Pritt.), P.Z.S. 1875, p. 616.

3S. Upperside. Fore wing light violaceous blue, whitish in the
cell and towards the outer margin, which, together with the costa,
is rather broadly uniform blackish brown, the border extending
into the middle of the cell. Hind wing greyish brown, darker
towards the costal margin, and violaceous towards the base. A
marginal row of distinct black spots extending from the apex to the
anal angle, bordered inwardly with a row of indistinct grey crescent-
shaped lunules, and outwardly with a clear white line interrupted by
the nervules; beyond this a blackish marginal line. Cilia greyish,
darker at each nervule.

Underside pale ashen grey, with the white-bordered markings
distinct and slightly darker than the ground-colour. Having much
the appearance of WV. euretes, 2 (P.Z.S. 1891, pl. xxxi. f. 7), but
with the submarginal row of lunules on both wings less distinct,
smaller, and more triangular. Head, thorax, and abdomen con-
colorous with wings. Antenne black with white spots.

A short black tail tipped with white on the lower median nervule.

Expanse !+ inch.

Mallicollo I., New Hebrides (Woodford) (Mus. G. & S.). Tanna
I., New Hebrides (8. M.).

The male of this insect in the British Museum is a uniform
violaceous blue, with very narrow linear brown borders.

This species does not appear to me very closely allied to any
other, but is perhaps nearest to NV. dion on the upperside of male
and female.

Mr. Butler has identified this insect with <Acrop.? argentina,
Prittwitz, from the Samoa Islands, but I feel confident that that
species is a Jamides, which is also Mr, Miskin’s opinion, as he
places it as a variety of L. (= J.) astraptes, Feld.

NACADUBA DION.

Polyommatus dion, Godt. Enc. Méth. ix. p. 679. n. 191 (1823).

Lampides perasia, Butl. P. Z. S. 1875, p. 616.

New Hebrides (G. F. Mathew) (Mus. G. § S.). Tanna I., New
Hebrides (B. 1).

Both sexes of this insect agreeing well with Australian specimens ;
two females, however, have slightly narrower black borders and con-
sequently a larger area of white, whilst another is quite normal.

Lycena perasia, auct. (nec Felder), from Australia, in my opinion
equals NV. dion. I have not seen a specimen from Amboina, whence
Felder’s type was obtained, but his figure seems to point to a form
which has the brown borders on the underside much broader than
any Australian specimens I have seen, and consequently a less extent
of white.

440 MR. H. H. DRUCE ON [May 17,

NACADUBA NEBULOSA, sp. n. (Plate XXVII. figs. 10, 11.)

Allied to N. ketria, mibi, but without the tails.

3. Upperside: colour the same; hind wing without the black
spots at the anal angle. Underside greyish creamy white, with
markings and spots arranged as in NV. keiria, but very faint and
indistinct.

Q. Uppersideas WN. keiria, 2 ; underside as male. Head, thorax,
and abdomen concolorous with wings. Antenne and legs brown,
spotted with white.

Expanse as JV. heiria.

Espiritu Santo I., Mallicollo I., New Hebrides (Woodford). New
Hebrides (Mathew) (Mus. G. & S.).

A form distinct from anything I have seen.

NACADUBA BIOCELLATA.

Lycena biocellata, Feld. Reise, Nov., Lep. ii. p. 280. n. 352, t. 35.
f. 14 (1865).

Lampides armillata, Butl. P. Z. 8. 1875, p. 614. n. 22.

New Hebrides (Mathew).

I have before mea male and two females of this pretty little species,
which agree exactly with two in the Hewitson collection from Swan
River; also with Felder’s figure.

Mr. Butler, in describing his species, evidently overlooked Felder’s
insect, at least he makes no mention of it.

The male is much like the female, but has the violaceous extending
almost to the margins of both wings.

I am unable to state positively whether this species should be
placed in Nacaduba or in Prosotas, as 1 have no specimen for dissec-
tion.

NACADUBA DEPLORANS.

Lampides deplorans, Butl. P. Z. S. 1875, p. 614. n. 23.

Maré I., Loyalty Is. (B. M.).

The type in the British Museum is the only example I have
seen. It certainly is not the female of N. dbiocellata, as both sexes of
that insect are in Messrs. Godman and Salvin’s collection.

NacapuBa?! CATOCHLORIS.

Lycena? catochloris, Boisd. Voy. Astr., Lep. p. 78 (1832); Butl.
P. Z. 8. 1874, p. 286.

Taiti, Society Is. ( Boisd.).

I have not been able to identify this species. Mr. Butler in 1874
suspected it to be a Danis, but as that genus is not known to occur
amongst these islands I think it will probably turn out to bea
Nacaduba.

Tuysonotis, Hiibn.

One species only of this genus has been discovered in these islands,
examples of which are contained in the British Museum and also in
our own collection.

THYSONOTIS CALEDONICA.

Lycena caledonica, Feld. Reise Nov., Lep. ii. p. 267, t. 33. f. 7
(1865).

New Caledonia (Feld.) (Mus. D.).

Mr. Kirby, in his catalogue (p. 346), places 7’. caledonica as a
synonym of 7’. schaeffera, but the whole upperside of the male, with
the exception of the anal angle of hind wings, is of a rich dark blue,
in that respect resembling 7’. cepheis from the Solomon Islands, but
darker. The underside of hind wing isa most brilliant rich dark gold.

The uppersides of the females of 7’. schaeffera, T. cepheis, and
T. caledonica are practically all the same.

JAMIDES, Hiibn.

The species of this genus from the South Sea Islands have been
supposed to occur only in their typical localities, but the numbers
obtained by Mr. Mathew and Mr. Woodford prove that this is not
the case—J. woodfordi having been received from Fiji, the New
Hebrides, and Tonga Islands.

All the species are very nearly alike on the undersides, but
although I have before me a good series of most of the species I am
unable to say that the colours merge one into another.

JAMIDES CANDRENA.

Lycena candrena, Herr.-Schaff. Stett. ent. Zeit. 1869, p. 74.

Lampides candrena, Butl. P. Z. S. 1874, p. 285.

Viti Levu I., Ovalau I., Vanua Valava I., Fiji Is. (Herr.-Schiiff.).

The only specimen I have seen is one in the British Museum
which Mr. Butler informs me was sent by Herrich-Schaffer under
his name. The wings appear to be exactly the same shade of blue
asin J. pulcherrima, but the spots on the hind margin of secondaries
seem to be absent, and the blue extends to the apex of the wing,

Judging from Herrich-Schiaffer’s description I should have identi-
fied the insect which stands under the name J. woodfordi as his
species, because, first, he states thatit is near L. kankena, Feld., which,
according to Dr. Felder, is similar to his Z. nemea in the-coloration
of the upperside, and, secondly, no black borders are mentioned in
the male ; now in the series of J. woodfordi before me several speci-
mens have the borders so narrow as to be almost imperceptible, and
until some one is able to compare the museum example with the
actual type it is impossible to be certain what J. candrena really is.

Mr. Miskin, Ann. Queensland Museum, no. 1, p. 51 (1891), states
that L. candrenais a synonym of L. (=Jamides) astraptes, Feld., and
on p. 54 gives N. Hebrides as a locality for L. dochus, Cr. There are
specimens in Messrs. Godman and Salvin’s collection of J. astraptes
from Amboina, Ceram, and Philippine Islands; all these have the costal
portion of the hind wings of a lighter and more shining blue than the
rest of the wings, in that respect differing from all the island forms
noted in this paper and resembling the Indian LZ. bochus, from which
they principally differ in having narrower black apical borders.

Four specimens of this insect in Messrs. Godman and Salvin’s
collection are all from Espiritu Santo Island. Mr. Butler describes
the type as a female; it is a male, and a female before me is without
the metallic gloss and has the borders considerably browner and
also broader, especially in the hind wing.

There are before me a large number of this insect from the Fiji
Islands, which varies a good deal in the width of the black borders
and also in the colour of the underside.

I have before noted (P. Z. S. 1891, p. 367) that J. campanulata
cannot be separated from J. woodfordi, and after carefully examining
the type of J. lobelia I cannot admit it as anything but a dwarf
specimen of J. woodfordi.

JAMIDES PETUNIA.

It has been suggested to me that the specimens which I described

1892.] THE LYCZNIDZ OF THE SOUTH PACIFIC. 443

are only J. woodfordi subjected to the action of damp. They are
dark bluish bronze and have a very distinct appearance, and for the
present I think it better to keep them separate. There are no speci-
mens in any other collection that I have seen which are anything
like them.

JAMIDES KAVA, sp.n. (Plate XXVII. fig. 15.)

The type in Messrs. Godman and Salvin’s collection and a speci-
men in our own from Fiji Islands are identical. This may prove to be
a variety of J. morphoides, but a good series of that species from the
New Hebrides does not show any variation.

A good series of specimens not varying to any appreciable extent,
and distinguished at once from J. woodfordi by their much darker
and richer blue. Lampides (=Jamides) phaseli, Mathew (the types
of which are now in Messrs. Godman and Salvin’s collection), from
the Claremont Islands, and which we have also from N. Australia, is
allied to this species, but is much more plumbeous on the upperside
and on the underside the white lines appear much more distinct. Mr.
Miskin, in the Annals of the Queensland Museum, no. 1, p. 59 (1891),
places this species in the genus Lyccenesthes, which is certainly an
error, as its hind wing possessing one tail only immediately shows. It
will be observed that in the same paper Mr. Miskin places 17 species
in Lampides, referred to ‘‘ Hiibn., Moore, Dist., and De Nicéville,”
but none of these authors use this name for any of the species he
places under it.

It is, I think, possible that the insect described by von Prittwitz
may prove to be the same as Mr. Butler’s J. carissima, but without
examining the type I fear it is impossible to be certain.

JAMIDES WALKERI, sp. n. (Plate XXVII. figs. 13, 14.)

Although a species of Nacaduba (ardates) is known to have

insect the same as J. carissima, as they do not occur together. The
other distinctions, though slight, seem constant. There are two pairs,
including the types, in Messrs. Godman and Salvin’s collection, and
one in our own. This is the only species in the genus without the
usual tail. The species is also in the British Museum.

I am still of the opinion that the species inhabiting these islands
should be separated from C. strabo, Fabr., but not having seen
Herrich-Schiffer’s type it is impossible to say whether the insects
before me represent his species. Felder’s Lyc. kandarpa, var. cale-
donica, from New Caledonia is an older name for the same insect,

1892.] THE LYCEZNID# OF THE SOUTH PACIFIC. 445

but as it is well known under the name C. platissa I do not care to
suggest another alteration in its synonymy.

The specimens I have examined show considerable variation in
size (some specimens from Samoa Islands being little more than half
that of others from the New Hebrides) and also in coloration,
some which I consider typical having a greyish-black outer marginal
line only, whilst others have the apex and outer margin broadly
greyish. The undersides also show considerable differences—some
having the spots and bands brownish and distinct, in others, again,
they are almost concolorous with the ground-colour of the wings.
These variations cannot be traced to any particular locality, as a
series from each shows all intermediates and extremes.

Mr. Miskin considers that the Australian insect should stand
under the name pseudocassius, Murray. Such being the case, he
must admit that 7. plinius and T. pseudocassius occur together, as
we possess specimens from India and Africa agreeing exactly with
others from Australia. Mr. Mathew obtained a number of this
insect in the New Hebrides, but I have seen it from none of the
islands eastwards.

There is in Messrs. Godman and Salvin’s collection a single female,
formerly in Mr. Mathew’s collection, labelled New Britain.

1892.] ON THE LAND-MOLLUSCA OF THE PHILIPPINES. 447

6. On the Geographical Distribution of the Land-Mollusca
of the Philippine Islands, and their Relations to the
Mollusca of the neighbouring Groups. By the Rev. A.
H. Cooks, M.A., F.Z.S., Fellow and Assistant-Tutor of
King’s College, Cambridge.

[Received April 20, 1892.]

The Land-Mollusca of the Philippines may be regarded as con-
sisting of two classes, those belonging to peculiar genera or subgenera
developed after the final separation of the group, and those belonging
to genera or subgenera common to the neighbouring islands. These
latter may again be subdivided into (1) Indo-Malay and (2) Moluccan
and Polynesian genera, according as the metropolis of their deve-
lopment lies to the S.W. or the S.E. of the Philippine group.

The object of the first part of this paper is to examine the distri-
bution of the genus Cochlostyla amongst the different islands of the
Philippine group. The Philippines are distinguished from every
other group throughout the Pacific, except the Sandwich Islands, by
the possession of an almost wholly peculiar and very conspicuous genus
of Land-Mollusca, of striking beauty in form and ornamentation, and
exceedingly rich in species’. The genus falls into 15 subgenera, the
majority of which are on the whole fairly well marked, although the
distinction between several of them is somewhat arbitrary. Nota
single island is without its representative of the genus, and the
species and even the subgenera are frequently much restricted in the
area of their distribution. The whole genus thus forms an interesting
clue by which to examine the problem of the ancient relationship of
the different islands to one another.

Preliminary Remarks on the Subgenera of Cochlostyla.

I have followed Semper’ in regarding Avina and Corasia as true
Oochlostyle, and von Méllendorff in adding * Ch/lor@a and* Ptycho-
styla and excluding’ Phenicobius. Semper admits that the only
distinction between Cochlostyla and Chlorea is that the latter exhibits
some small anatomical difference in the genital apparatus, and this,
as von Mollendorff justly remarks, is hardly sufficient reason for
keeping it separate. The division of subgenera adopted by Semper

? About 240 are enumerated by Hidalgo, ‘Journ. de Conch.’ 3° sér. xxvii.
1887, pp.,111-192 ; but the list might be considerably narrowed by the reduction
of many “ species” to the rank of varieties, and the exclusion of several which
are not true Cochlostyle.

448 REV. A. H. COOKE ON [May 17,

in the ‘Reisen’ is admitted, even by its author, to be hardly
satisfactory. But there is practically a general agreement between
Semper and Pfeiffer *, since both agree in the limitations represented
by about 10 of the subgenera, the chief points of difference arising
with regard to the respective limits of Calocochlea and Helicostyla,
of Helicobulimus and Orthostylus, of Orthostylus and Canistrum,
and the restriction of Canistrwm proper. The distinction, if any,
between some of these groups is, unless and until some definite
anatomical difference is established, at best arbitrary. After careful
consideration I have decided to abolish Helicobulimus altogether,
merging it in Orthostylus. The species are in any case few (Pfeiffer
enumerates only 5, and one of these, grandis, Pfr., is better classified
as Calocochlea), and different authorities are much at issue with
regard to referring specific forms to one group or the other. This
seems sufficient reason for refusing to draw a line between them.
With regard to Orthostylus and Canistrum (Pfr.), there is a very
long series of forms ultimately connecting such typical Orthostyli as,
e. g., daphnis, Brod., and rufogaster, Fér., with elongated shells like
camelopardalis, Brod., and nympha, Pfr. But the extremes are so
wide apart that it may be worth while to try to separate them, and
I do so by regarding pictor, Brod., as a sort of border-line form,
removing it from Orthostylus, and considering it and all the more
elongated forms as belonging to a separate group (Hypselostyla,
Mts.). This group is practically identical with Semper’s ‘ Klongate,’
for there is strong ground for restricting, with Semper, the group
Canistrum to a peculiar section of shells*, the type of which is
ovoidea, Lam. (=Zluzonica, Moérch, = euryzona, Ptr.).

The localities given in each case have been most carefully con-
sidered, and no species has been taken into account whose locality
is not regarded as authoritative. Thus the locality ‘ Philippines,’ so
often given by the older writers, is useless for the present purpose,
and species not further localized (a considerable number) have been
neglected altogether. Recent investigation has been more exact in
its record of localities, aud in the present paper 180 species in all are
brought to account. Further, it has been found necessary to neglect
Cuming’s authority as establishing any locality whatsoever. Those
familiar with his method of preserving localities will understand this,
and it need only be added that Semper and von Méllendorff are
continually at issue with him. He may be taken as confirming, but

a Hypselostyla; the remaining two appear doubtful.

authors just mentioned, Hidalgo, von Martens, and Dohrn.
Hidalgo’s work requires special watchfulness, but on the whole his
localities are trustworthy. No locality from Pfeiffer has been accepted
unconfirmed.

No especial care has been taken to weed out synonymous species.
This would involve another heavy piece of work, and would not
materially affect the results arrived at.

This subgenus is widely distributed without being specially cha-
racteristic of any island. It is not recorded from the large islands of
Leyte and Samar, nor from S. Luzon, which is closely related to
them. The true position of the so-called Chlorea pelewana, Mouss.,
from the Pelew Islands, cannot be said to be ascertained as yet.

It occurs also in Tukan Bessi (off S.E. Celebes), perhaps in the
Tular Islands (between Gilolo and the southerh point of Mindanao),
in Amboyna, in New Guinea, and in the Solomon Islands. It may

but as it does not appear to have been discovered anywhere else, there is con-
siderable probability that the locality may be correct.

3 Mollendorff, Nachr. mal. Gesell. xx. 1888, p. 65. A tablet in the Brit.
Mus. has on the back, in Cuming’s hand, “Island of Luban, leaves of trees.”
This locality had never been confirmed until one of yon Mollendorft’s collectors
found the species living on Luban. Pfeiffer classified it as Stylodonta, Tryon as
Nanina! Semper (Reisen, IT. iii. p. 181) was the first to regard the species as
Cochlostyla. He placed it in Calocochlea, suggesting, however, that a special
group should be formed for so remarkable a shell.

454 REV. A. H. COOKE ON [May 17,

channel, contains representatives of no subgenera which do not occur
in Luzon. Only two subgenera (Corasia and Calocochlea) appear
to be found there.

Luzon.—The great size of this island, exceeding as it does in area
all the other islands, excepting Mindanao, taken together, and its
wide extension to the S. and E., cause it, besides developing a rich
fauna of its own, to receive immigrants from subgenera not indigenous
to it. Thus there is no group which is not represented on Luzon,
with the exception of those peculiar to Mindoro and Luban, but, on
the cther hand, there is no group (except Pfeiferia) peculiar to it.
It is characterized by a rich development of the four subgenera
Corasia, Calocochlea, Helicostyla, and Orthostylus ; its neighbour-
hood to Marinduque gives it its 2 species of Phengus, to the central
group its 2 species of Hypselostyla. Catanduanes, Polillo, and
Alabat, the three islands on its eastern side, the fauna of which is
well known, present no peculiar features; the channels separating
them from Luzon are shallow, and they are practically a part of the
main island.

Marinduque.—This island, although in other respects closely
related to Luzon, stands out distinct from it in several respects, and
is by no means so closely related to it as the islands just mentioned.
The channel separating it from Luzon is deep, and apparently only
just fails to exceed 100 fathoms in depth throughout its length.
It is the metropolis of the subg. Phengus, 7 out of the 9 known
species being found there. No species of Calocochlea, so abundant
in Luzon, appears to occur. Orthostylus is abundant, and Hypselo-
styla is represented by one species.

Leyte and Samar.—These two islands, which are separated from
one another by a very narrow and shallow channel, are closely related.
The San Bernardino channel, which separates Samar from Luzon, is
not of great depth, and accordingly no subgenus occurs on these two
islands which does not also occur on Luzon. On the other hand,
the Surigao passage, which separates Leyte from Mindanao, is, at
least in part, of considerable depth, and we find accordingly that
two out of the three subgenera hitherto recorded from Leyte do
not occur in Mindanao. Neither of the islands can be said to be
well explored. Only Calocochlea and Orthostylus are recorded from
Samar, and the same two, together with Hypselostyla, from Leyte.

Burias and Masbate.—The subgenus Canistrum, so far as our in-
formation goes, appears to be peculiar to these two islands. This is
the more strange, because the channel separating them from Luzon
and from Samar is of no great depth, and the stretch of sea between
Masbate and the N. coasts of Negros and Cebu is the largest piece
of shallow water in the Philippines, scarcely exceeding 30 fathoms
at any point. Hastward of Burias and Masbate the depths are con-
siderable, and completely separate these islands from the Tablas-
Romblon-Sibuyan group. ‘Ticao does not appear to have been
explored. Orthostylus is abundant on Masbate.

Tablas, Romblon, Sibuyan.—These three islands, which are
separated by very deep water from all their neighbours, are closely

related to one another. They have no subgenus peculiar, but their
general relations are rather with Luzon than with the central islands.
One species of Phengus indicates relations with Marinduque, while
the complete absence of Hypselostyla, so common in Panay, separates
them from the central group.

Cebu and Bohol.—These islands, with Panay, are the metropolis
of Hypselostyla, which has spread northward to Luzon. Both are
sharply separated from Mindanao, since neither Orthostylus, which
is abundant in Cebu and Bohol, nor Hypselostyla is represented in
that island, while on the other hand Hudowus, which is abundant in
Mindanao, is entirely absent from Cebu and Bohol. Corasia is
abundant in both islands; Aaina is not recorded from Bohol, while
it is abundant in Cebu, which indeed contains 6 out of the 10 existing
species. Calocochlea, on the contrary, which is entirely absent from
Cebu, occurs freely in Bohol *.

Panay.—This island appears, on a consideration of its fauna, to
be rather isolated ; but perhaps this may be accounted for by the
fact that its nearest neighbour, Negros, has been scarcely explored.
Its relations are with the central group, Hypselostyla being abundant
and all its species peculiar to Panay. Orthostylus is the only other
subgenus known to occur. Thus no connection is indicated with
the Tablas-Romblon-Sibuyan group or with Mindoro.

Mindanao (including Surigao and Camiquin).—This great island
presents some remarkable features. Amina is entirely absent, while
Calocochlea is exceedingly abundant. Corasia appears to be con-
fined to the extreme S., where itisabundant. Phengus, Helicostyla,
and Cochlodryas are absent, and, what is more remarkable, Ortho-
stylus and Hypselostyla, so abundant on Cebu and Bohol, do not
occur, thus indicating a very considerable severance between
Mindanao and the central islands. The channel immediately north
of Mindanao is not well surveyed, but appears undoubtedly to be of
very considerable depth, 185 fathoms having been recorded by the
‘Challenger’ close under the N. coast of Camiguin. The Surigao
strait appears to be rather shallow on its eastern side, but as it opens
out towards the west the depth appears rapidly to increase. <A
special feature of Mindanao is the development of Hudoxus, found
elsewhere only in Luzon (?) and Catanduanes*. So far as we can at
present make out the relations of Mindanao are rather with Luzon
than with the islands immediately contiguous.

There seems every probability that the western part of Mindanao
was once for a considerable time a separate island, completely dis-
connected from the central and eastern portions. The low and
narrow neck of land, scarcely 20 miles across, lying between Iligan

1 Hidalgo (Journ. de Conch. 3° sér. xxvii. p. 175) gives Cebu as a habitat for
calobapta, Jon. ‘This must be a mistake, as the species is a Prochilus, which is
confined to Mindoro and, perhaps, the Cuyos.

* Hidalgo (Journ. de Conch. wt sup. p. 146) gives C. roissyana from ‘Surigao,
dans ’ile de Mindanao.” I do not know any other authority for believing that
roissyana is not peculiar to Mindoro. There is probably a misidentification of
C. spherion, Sowb.

Bay in the N. and Illana Bay in the S., appears to me to represent the
original channel of separation’. Corasia occurs all over the island ;
its appearance and development must therefore have preceded the
separating of the western portion. But Calocochlea and Eudoxus,
the latter of which is almost peculiar to Mindanao, occur only in
the N. and E. (e. g. smaragdina is found from Mainit in the extreme
N. to Davao on the S.E. coast), and are not recorded from any
point west of the narrow isthmus. Again, the section of Chloritis
of which H. spinosissima, Semp., quieta, Reeve, and sanziana, H.
& J., are well known examples, is almost peculiar to Mindanao, but
is only found in the district to the W. of this peninsula, and does not
appear to have penetrated the main portion of the island.

One species of Corasia (zamboange, H. & J.) is recorded from
the island of Basilan (S. of Mindanao) ; the species is not peculiar,
and occurs also on Mindanao.

Mindoro.—The general relations of this island are very remarkable,
and cause it to stand out as by far the most isolated of the whole
Philippine group. A glance at the map might incline us to regard
it as a link between Luzon and Panay, with close relations to the
former island, and with no cause for especial individuality. Mindoro,
however, is incomparably the most isolated of all the Philippines. It
contains one, possibly two, absolutely peculiar subgenera, which are
very well marked, and of which the nearest relations appear to be with
Hypselostyla. In other words, the relations of Mindoro, are, so far,
but only very remotely, with Panay. At the same time, however,
no existing subgenus appears to be common to the two islands.
Probably further exploration may detect Chlorea, Corasia, and
Calocochlea on Panay ; but that would not bring its relationship to
Mindoro at all closer, since these subgenera are known from almost
every island. With Luzon Mindoro has, excluding the three sub-
genera universally prevalent, only one subgenus (Helicostyla) in
common. All the species, however, are peculiar to Mindoro.
Through this subgenus Mindoro appears also related to the Tablas-
Romblon-Sibuyan group, and also to the Cuyos Is., but not to Panay.
Axina, Eudoxus, Orthostylus, Phengus, Canistrum, and Hypselostyla
are completely absent. Cochlodryas, however, is common to Min-
doro and Burias only.

Cuyos Is.—These islands are very imperfectly known, but what
little information we have tends to relate them with Mindoro, and
not with Panay or Palawan. If Cuming’s authority is to be trusted,
the only two subgenera which occur in the Cuyos (Helicostyla and
Prochilus) are common to Mindoro, but do not occur either on Panay
or Palawan.

Iuban.—This little island, lying almost between Luzon and
Mindoro, must have been, in all probability, isolated for a long time.
It contains one well-marked subgenus, Ptychostyla, which is quite
peculiar. Deep water surrounds the island on every side.

1 Most atlases, even the most recent, erroneously represent this isthmus as
traversed by a lofty range of mountains.

458 REV. A. H. COOKE ON [May 17,

Conclusions with regard to the Development of Cochlostyla.

It is probable that the distribution of Oochlostyla, above indicated,
is due primarily to the union and separation of the various islands,
perhaps more than once repeated. It can hardly be an accident
which excludes Orthostylus, Hypselostyla, and Helicostyla from
Mindanao, while Corasia and Calocochlea are not excluded, or which
so sharply separates Mindoro from its near neighbour Luzon. The
accompanying map (p. 455) shows that an elevation of the sea-bottom,
of not more than 100 fathoms, would be sufficient to unite together
all the great islands of Luzon, Leyte, Samar, Burias, Masbate, Bohol,
Cebu, Negros, and Panay, not one of which is specially characterized by
any one particular group, but all of which have a great many groups
in common. The islands which would still remain isolated would
be Luban, Mindoro, the Tablas-Romblon-Sibuyan group, Siquijor,
and, possibly, Mindanao, all of which are characterized by the
prominent absence or presence of marked subgenera’. When we
know that the whole of the adjacent island of Borneo has been sub-
merged for a depth of probably twice this amount, the probability
that similar oscillations of level have occurred in the Philippines is
largely increased, and, as a matter of fact, comparatively fresh
coralline limestone occurs in many places in the islands at a height
of at least 2000 feet above the sea”. There is no need to assume
that the elevation and submergence affected all the islands simul-
taneously, or that it has not been several times repeated.

The conclusions that we arrive at by a study of the genus Cochlo-
styla are not illustrated, to any very considerable extent, by the
distribution of other genera of Land-Molluseca occurring in the
Philippines*. The natural inference is, that the genus Cochlostyla,
as a whole, is of comparatively recent development, dating, in all
probability, from a time much posterior to the introduction of the
bulk of the Indo-Malay genera, and subsequent to the final separation
of the group from Borneo and possibly from Celebes. The oldest of
the subgenera appear to be Chlorea, Corasia, and Calocochlea,
which are universally distributed, being common alike to Luzon,
Mindoro, Mindanao, and the central group. Orthostylus and
Hypselostyla were probably developed in the central group after the
final separation of Mindanao. Mindoro and Luban (the only
possessors of peculiar subgenera) must have been isolated very early,
although perhaps the union of Mindoro with the Cuyos Is. continued
after the separation of the former from Luzon and from Panay.

1 The soundings in the Surigao Strait are, even in the most recent charts ,
yery infrequent, and the extent of shallow water between Mindanao, Leyte, and
Samar is probably exaggerated on the accompanying map.

2 Mr. Everett writes to me as follows:—‘ Oebu, Siquijor, part of Bohol,
almost all Leyte, N.E. Mindanao, Tablas, Romblon, and parts of Samar and
Luzon are covered with thick caps of recent coral-limestone. There is a good
deal of limestone in Palawan and the Calamianes. Theisland of Mindorois...
not overlaid (at least as seen from the sea) by recent coral-limestone, as so many
of the Piatra group are,”

group.

1892.] THE LAND=MOLLUSCA OF THE PHILIPPINES. 459

Relations of the Philippines to the neighbouring Islands.

The Philippines are connected with Borneo, and through Borneo
with Java, Sumatra, and the mainland of S.E. Asia, by two dis-
tinct ridges or banks of elevation, which enclose between them the
Soo-loo or Mindoro Sea. The first, or westernmost, of these, which
stretches from a point S.W. of Mindoro to the northern Cape of
Borneo, consists of the islands of Busuanga, Calamian, and Limi-
capan, of the great island Palawan or Paragua, and the smaller
islands Balabac, Balambangan, and Banguey. The entire length of
this ridge is somewhat over 400 miles, not including the channel
(about 50 miles wide at its narrowest point) between Busuanga and
Mindoro. Of this, about 350 miles is land, and about 50 miles water
of less than 50 fathoms in depth. The easternmost bridge, which
stretches from Zamboanga, the extreme western point of Mindanao,
to the N.E. corner of Borneo, consists of a continuous chain of
small islands, the Basilan group, and the Soo-loo Archipelago.
This ridge is only about 225 miles in length, but the largest island
of the chain is scarcely 40 miles long, as compared with Palawan,
which is over 250.

On either side of both ridges the depth of the seais profound. A
deep submarine valley’, with soundings of 670 fathoms to 1200
fathoms (the so-called ‘ Palawan passage ’), runs in a N.E. and S.W.
direction immediately west of and parallel to Palawan. The Soo-
loo Sea is still deeper, soundings of 2225 fathoms and 2550
fathoms having been obtained off the S.W. coast of Mindanao,
while profounder depths still have been fathomed in the Celebes Sea.
A curious point about these ridges is, that a chasm occurs in each
of them, and in each of them at one end, but not at the same end
in both. The Palawan ridge is interrupted at its extreme northern
end, between Busuanga and Mindoro, by a channel 50 miles broad
and about 600 fathoms in depth (the Mindoro Strait). The Soo-
loo ridge is interrupted at its extreme southern end by a channel
only about 20 miles in width, but in parts over 500 fathoms in depth
(the Silutu passage). Were it not for these channels, a rise of
100 fathoms in elevation of the sea-bottom would make a double
direct communication by land between the Philippines and Borneo.

There can be no doubt that Indo-Malay species of Mollusca have
penetrated into the Philippines, in very early times, by both these
ridges. Thus we find abundant in the Philippines the great Nanine
and Cyclophori so characteristic of the larger Sunda Islands. Four?

* Tt is important to notice this, since the ‘ Palawan passage’ might be ex-
pected to mean the strait between Palawan and Borneo, whereas it means the
fairway between Palawan and the dangerous ground to the west. Occasionally
we find ‘Palawan passage’ given by inexact writers as a locality for Land-
Mollusca, which is much as if ‘ Mozambique Channel’ were given as a locality
for a Madagascar Cyclostoma, or ‘ Bass’ Strait’ fora Tasmanian Helix, Pfeiffer
(Mon. Hel. iv. 362) gives ‘ Palawan passage’ for his Bulimus trailli, and Tenison-
Woods (Proc. Linn. Soc. N.S. Wales, ser. 2, iii. p. 1003) gives the same locality
for Camena trailli and palawanica.

* Amphidromus jayanus, Lea, is probably not Philippine, and certainly not
a Cochlostyla. Godwin-Austen records it (as a Gini from Borneo
(P. Z. 8. 1891, p. 45).

460 , REV. A. H. COOKE ON [May 17,

species of Amphidromus are known from the Philippines (Sumatra 5,
Java 15, Borneo 6); of these two get no farther north than Balabac,
another occurs on Palawan, while two others are met with in Min-
danao, and one of these has penetrated as far as Bohol and S. Leyte’.
A detailed survey of some of the principal genera common to the
Philippines and the neighbouring islands will be given below.

It would seem as if the connection which probably at one time
existed between Palawan, Busuanga, and Mindoro was not directly
across the present Mindoro Strait, where the depth is extreme. The
Cuyos Is. appear to have shallow water to the W., and decidedly
deeper water to the E.; thus their connection is with Palawan now.
Again, the water shallows rapidly towards the S.E. end of Mindoro
Strait, and is broken by islets and submarine banks, which extend
from the S. point of Mindoro towards Panay and also towards
Busuanga ; the water, however, between these banks and islets is deep,
being generally over 100 fathoms, and often more. The water off
the N. and W. sides of Panay has not been very accurately surveyed,
but isin all probability extremely deep. It would thus seem probable
that any connection which may have existed between Mindoro and
Busuanga (and a consideration of the very remarkable Helicide of
both islands makes such a connection extremely probable) followed
the line of shallower water at the E. end of the Mindoro Strait, and
possibly extended some distance eastward towards Panay.

It will now be interesting to examine the Land-Mollusca of these
two ridges, with a view of discovering whether or not they belong to
the Philippine fauna.

Unfortunately, our knowledge of the Land-Mollusca of the Soo-loo
ridge is meagre inthe extreme. We know that Basilan, Lampinigan,
and Malanipa are, by their Cochlostyle, closely related to Mindanao.
We know also that one species of Cochlostyla (lais, Pfr.) occurs on
Soo-loo Is. Tawi-tawi” is quite unexplored. The Mollusca of
Bongao, the last island at the Borneo end of the chain, are known.
Eleven species in all are enumerated, five of which show distinct
relations with Borneo.

The following species are known to occur on Basilan:—

Cochlostyla zamboange, H.& J. Also occurs in Mindanao.

Xesta mindanaensis, Semp. 3 Mindanao.

Chloritis sanziana, H. & J. Mindanao.

Obbina rota, Brod. ms Bohol, Siquijor, &c.

1892.] THE LAND-MOLLUSCA OF THE PHILIPPINES. 461

Thus Basilan is, as might be expected, thoroughly Philippine,
not possessing even one peculiar species.
The Mollusca known from Malanipa are :—

Xesta mindanaensis,Semp. Also occurs in Mindanao.

Chloritis sanziana, H. & J. ss Mindanao.
Obbina bigonia, Fér. - Mindanao, Leyte, Samar.
Leptopome vitreum, Less. * Philippines generally.

The only Mollusea which appear to be known from Soo-loo are:—

Trochomorpha metcalfei, Pfr.
Cochlostyla lais, Pfr.
Melania soolooensis, Brot. ,
* Cyclotus suluanus, Mallf., MS. + Cy. Orn fd pa

According to Hidalgo*, Cochl. dais occurs in N. Mindanao. The
species is probably only a variety of puella, Brod. Pfeiffer originally
described it from the Philippines generally ; in the ‘ Novitates,’ iv.
tab. 126. ff. 6, 7, p. 114, he figures a var. said to be from Tukan
Bessi, a locality which I greatly doubt.

In the absence of any information as to Tawi-tawi, it is impossible
to say how far Philippine influence extends along this ridge.

The Mollusca known ® from Bongao are :—

Plectotropis squamulifera, MOllf. Peculiar.
Macrochlamys angulata, MOllf. Peculiar.
Trochonanina conicoides, Metc. Peeuliar, o'r» ‘Ler ie -
Opeas, two species not identified.

Opisthoporus, sp. (possibly a Cyclotus).

Leptopoma, sp.

Lagochilus quinqueliratus, Mollf. Peculiar.

Alyceus excisus, MOllf. Peculiar.

Diplommatina roebelini, Mollf. Peculiar.

Pupina ottonis, Dohrn. Also occurs in Philippines.
Helicina martensi, Issel. 3 Borneo.

Thus six out of the eight known species are peculiar, while of
the remaining two, one occurs in the Philippines and one in Borneo.
As to genera, no exclusively Philippine genus occurs, while Plecto-
tropis, Macrochlamys, Trochonanina, Opisthoporus, Lagochilus, and
Alyceus are Indo-Malay. In spite, then, of the deep intervening
channel, Bongao is distinctly Bornean, and, in spite of the chain of
islands with shallow water between them, distinctly non-Philippine.

Coming to the western ridge, the Mollusca known from Balabac 4
are as follows :—

Amphidromus ° ? entobaptus, Dohrn. Also occurs in Palawan.

Thus we find, even at the extreme Bornean end of this ridge,
Philippine influence of considerable importance. The Bornean
Amphidromi are counterbalanced by the Hadra, which belongs to
the remarkable group of which the metropolis is Palawan, and by
the single Cochlostyla. Opisthoporus, again, is Indo-Malay, while
in the genus Leptopoma the preponderance, in species at any rate,
is towards the Philippines. Quadrasia is a remarkable freshwater
form, apparently allied to Planazis, and quite peculiar to Balabac.

Of the 30 species above enumerated, 11 are peculiar to Palawan
and the adjacent islands, while, of the remaining 19, 13 occur also
in the Philippines only, 3 in Borneo, 2 are common to the Philip-
pines and Sunda Islands, while one is assigned, perhaps wrongly, to
China. If, however, we take the genera concerned, we find that 3
(Cochlostyla, Hemitrichia, Euplecta) are Philippine ; 6 (Hemiplecta,
Trochonanina, Amphidromus, Eulotella, Opisthoporus, Cyclophorus)
are Indo-Malay ; while the remainder are Moluccan and Polynesian
genera which have spread into the Philippines and Sunda Islands.
Palawan, therefore, affords a link between the Philippines and the
Indo-Malay islands, without being very markedly allied with either
group. Of Indo-Malay genera which do not appear to reach to the
Philippines proper, it has Opisthoporus, while Amphidromus and
Eulotella are but scantily represented there. Again, of genera
peculiarly Philippine, it has the three above mentioned, so that
the balance is fairly even. It is in its operculates, Leptopoma and
Cyclophorus, that Palawan shows its closest relation to the Philip-

ines.
The Mollusca known from Busuanga are as follows :—

Ennea (Diaphora) méllendorfi, Hid. Peculiar.

Cochlostyla * satyrus, Brod. Palawan and Balabac.
Cyclophorus smithi, Hid. Peculiar.

It is evident from this list that, as would be expected, Philippine
influence is preponderant in Busuanga. Of the 23 species known, 12
are peculiar, and, of the remaining 11, 2 are also peculiar to Palawan
and Balabac, 8 are common to the Philippines, and only 1 appears to
occur in Borneo. Amphidromus, which occurred in Palawan, is not
represented, but relationship with Palawan is sufficiently attested by
the one Cochlostyla and by Hadra polychroa. The Indo-Malay Opis-
thoporus which reached Palawan appears to reach no farther. The
occurrence of the Diaphora section of Ennea, which is only found
elsewhere in Luzon, is a markedly Philippine element. Kaliella is a
thoroughly Indo-Malay genus, which occurs sparingly in Java,
Borneo, and the Philippines. The two species classified as Zrocho-
morphoides are of doubtfui generic position. Originally described
as T'rochomorpha, they were afterwards placed by their author in
Geotrochus. In seems better to assign them to the genus in which
Von Martens has placed several other Geotrochoid species (e. g.
bantamensis, Smith, from Bantam I., off Java, and niahensis, Godw.-
Aust., from N. Borneo), until their anatomy has become definitely
known.

By far the most interesting part of the molluscan fauna of
Busuanga are its Helices. Only three are known, viz. campanula,
Pfr., bintuanensis, Hid., polychroa, Sby. These three species
belong to two groups closely related to one another. One of these
groups is represented in Palawan, the other in Mindoro, Busuanga
uniting the two by possessing both. There can be little doubt of the
very close relationship of campanula and bintuanensis (together
with ceres, Pfr., probably from this same locality) with the species
so long regarded as a group of Cochlostyla (Phenicobius), but
now separated off by von Mollendorff as a group of Helices of the
Cameena family. The curiously stumpy form, thick and roughly
toothed lip, and often wrinkled sculpture are marked points of
similarity throughout. The other group, that of polychroa, is more of
the normal helicoid type, but is linked with Phenicobius by the form
trailli, Pfr., which presents points of analogy with both groups.

This occurrence of a number of large Helices of very restricted
distribution (Phenicobius being peculiar to Busuanga and Mindoro,
and the polychroa group to Busuanga, Palawan, Balabac, and perhaps
N.E. Borneo) is exceedingly remarkable. The evidence that the
polychroa group extends to Borneo is not strong. WH. ¢railli and H.
palawanica are given from Borneo in the Brit. Mus. on the authority
of Mr. Ussher, Consul at Labuan about 15 years ago. Issel, however,
in his monograph of Bornean Mollusca, gives these same species, not
from Borneo, but from ‘ Stretto di Palawan,’ which probably means

1 As the var. fischer?, Hid.

1892. | THE LAND-MOLLUSCA OF THE PHILIPPINES. 465

Balabac. The mistake about “ Palawan passage,” alluded to above,
has perhaps induced collectors to assign to both sides of the supposed
‘* passage ”’ species that really came from one side only. The only
form that appears to have any real authority as coming from Borneo
is H. dorie, Dohrn, and I do not feel absolutely certain even about it,
while Dohrn himself is very doubtful. But, whether the group be
represented in Borneo or not, it is interesting to consider the relation-
ship of these two very isolated groups of Helices, which, it may be
remarked, afford very strong evidence for a land connection at
some point between Mindoro and the Calamianes. It appears to
me that both of these groups find their nearest relations in an
easterly and not in a westerly direction—the Phenicobius group
being nearly akin to the well-known forms mamiilla and papilla, from
N. Celebes, and these to concisa, Fér., from Waigiou, and quoy?,
Desh., from Celebes ; the polychroa group to shells of the type of
rehsei, Mart., from N. Guinea, and dupuyana, Cpr., from N.E. Aus-
tralia. It is certain that, as far as these regions are concerned, it is
only in N. Guinea and N. Australia that Helices are found of the
size and general texture of those under consideration. And it is
perhaps worth while pointing out other affinities of the same kind.
The remarkable H. antigua, Ad. & Rve., from N. Borneo, appears
closely allied to no other shell but Jeonardi, Tapp.-Can., from
N. Guinea. The unique H. plurizonata, Ad. & Rve., found during
the ‘Samarang’ voyage in Mindanao, is very nearly related to
lacteolota, Sm., and agnocheilus, Sm., both from N. Guinea*. The
Corasie of the Philippines are closely related to a group of shells
which attain their maximum development in the Solomon Islands.
The section of Chloritis which includes such Helices as guieta, Rve.,
brevidens, Sby., spinosissima, Semp., saulie, Pfr., sanziana, H. & J.,
caliginosa, Ad. & Rve., and philippinensis, Semp., has its nearest
relations in N. Guinea, Torres Str., and N. Australia. And it is
perhaps worth noticing that the Philippine Chlorites just mentioned
appear to be restricted to the two islands of Mindanao and
Mindoro, i. e. just where the two ridges of connection impinge upon
the Philippine group.

These facts seem to point to a land connection, no doubt of
extreme antiquity, which admitted of Land-Shells of a Papuan and
N. Australian type finding their way in a westerly direction. I am
therefore inclined to regard Phenicobius and the polychroa group,
as now occurring in Palawan, Mindoro, and the adjacent islands,
as a sort of survival of a fauna which perhaps had once a much more
extended range. It is a significant fact that almost the only other
Helix from the E. Indies generally which in shape at all approaches
the smaller forms of the Phenicobius group is H. codonodes, Pfr.,
from the Nicobars. It is possible that eventually fossil or subfossil
forms may be discovered in Sumatra and Java which will place
this at present isolated form in continuous geographical connection
with the apparently related fauna of Busuanga and Mindoro.

’ Had the ‘Samarang’ been anywhere near N. Guinea, one might have

been disposed to believe that the locality for plurizonata was erroneous; its
facies is so strongly Papuan. :

466 REV. A. H. COOKE ON [May 17,

A word may be added with regard to three groups of islands
which link the Philippines with other points of geographical
interest. These are the Tular Islands, the Talautse Islands, and the
Bashee or Batan Islands.

The Tular Islands are situated between Mindanao and Gilolo, in
Lat. 4° N., Long. 127° E. The only Mollusca which appear to be
known from them are ' Helix physalis, Pfr., and Partula newcom-
biana, Hartm. Ancey * doubts the correctness of the locality for the
latter (Salisbaboe Island, one of the group). Itis certainly, if correct,
the most westerly Partula known, the few species from the Pelew
Islands coming next. The Tular Islands are known to be volcanic, and
a more thorough knowledge of their fauna, as illustrating the relations
between Mindanao and Gilolo, would be most interesting. The
depth of water, both to the north and south of the group, is
extreme.

From Sanghir, the Jargest of the Talautse Islands (situated in
Lat. 3°N., Long. 125° E.), the only Mollusca known are Cyclophorus
sericatus, Rents, ., and Obba linneana, Pfr. The latter is a very
interesting shell, and approximates closely to the Celebesian forms
mamilla, Feér., ond quoyi, Desh. In the Brit. Mus. there is a
tablet of Corasia leucophthalma, Pifr., from Sanghir Island, but I do
not feel confident of the authority.

The Bashee or Batan Islands, lying midway between Luzon and
Formosa in Lat. 21° N., Long. 122° E., appear not to have been
visited by a naturalist since the voyage of the ‘Samarang.’ They are
a continuation of the volcanic chain which runs through the
Philippines, Formosa, and the Loo-Choo Islands to Japan and
Kamtschatka. The depth of water all round them is profound, 1000
fathoms being recorded immediately off the S. point of Formosa,
while the Ballintang Channel, which separates the Bashee Islands
from the Babuyanes, is certainly of great depth. The only Mollusca
known from these islands are Helix batanica, Ad. & Rve., Cochlo-
styla ? speciosa, Jay, and Bulimus kochii, all from the island of
Ibugos (‘Samarang,’ Zoology Preface, Narrative, vol. i. p. 72).
Helix batanica, a sinistral species, appears to be of a thoroughly
Chinese or Formosan type, belonging to the same section as
peliomphala, Pfr., formosensis, Pfr., and bacca, Pfr. The Cochlostyla,
on the other hand, is of course Philippine, and it is very remark-
able that the species should occur on an island separated by such
great depths from the Philippines proper. What the exact species
may be is uncertain. Adams originally considered it to be C. speciosa.
Reeve afterwards described it (Conch. Ic., Helix, pl. ix. f. 2) as
batanica, afterwards altered to volubilis. Pfeiffer regarded it as
either his dubiosa or as decipiens, Sowb. Uidalgo thinks it a variet
of damahoyi, Pfr. (Journ. de Conch. 1887, p. 129). What
‘ Bulimus kochii’ may be (Adams says it occurred in three varieties,

but he does not figure any) I am quite unable to suggest. If an
Amphidromus, the balance of connection would be, on the whole,
with Formosa. The further investigation of the Mollusca of this
interesting group is very desirable.

In the following table (pp. 468, 469) are examples of Indo-Ma-
layan genera which reach the Philippines.

The following Indo-Malayan genera occur in the Philippines, but
have not yet been detected in Sumatra, Java, or Borneo, viz. :—
Hypselostoma (philippinicum), Plectopylis (polyptychia, trocho-
spira), Ditropis (mira, cebuana, quadrasi), Cyathopoma (cornu,
meridionale, aries).

Of Moluccan and Polynesian genera occurring in the Philippines,
and gradually diminishing through the Sunda Islands west-
ward, the following may be mentioned :—Trochomorpha: Philip-
pines 9, Borneo 8, Java 8, Sumatra 4; Helicina: Philippines 16,
Borneo’ 3, Java 1, Sumatra 0; Leptopoma: Philippines 31,
Borneo 11, Java 2, Sumatra 1 ; Cyclotus: Philippines 18, Borneo 6,
Java 2, Sumatra 1; Pupina: Philippines 5, Borneo 3, Java 5,
Sumatra 3. Two species of Tornatellina (manillensis, ringens) occur
in the Philippines, but not farther westward, one of Endodonta
(philippinensis), and one of the Leucochilus section of Pupa (the
pan-Polynesian pediculus).

There seems to be a good deal of misunderstanding with regard
to the island Tukan Bessi (variously spelled Toekang Besi, Toukang
basi, Tukang Bessie, Toekun Bessi). It originally came into notice
as the habitat of three supposed Cochlostyle (thomsoni, Pir.,
indusiata, Pfr., tukanensis, Pir.), described (as Helices) by Pfeiffer
in Malak. Blatt. xviii. 1871, p. 120, f., from the collection of
Mr. J. H. Thomson; the same locality is repeated in each case in
the ‘ Novitates,’ vol. iv. pp. 71-73. Kobelt, in his papers on geo-
graphical distribution, quotes Issel (Monogr. Bornean Mollusca) as
referring one of these species to ‘‘the small islands north of Borneo,”
and in his list gives Cochlostyla lais, tukanensis, and physalis all
from “ Toekun Bessi.”” Von Mollendorff (Jahrb. deutsch. malak.
Gesell. xiv. p. 285) remarks that this island, as well as Tular and New
Beland, lies between the 8. point of Mindanao and the Moluccas. ‘The
only Tukan Bessi with which I am acquainted is off the S.E. point
of Celebes, in Lat. 4° 8., Long. 124° E., and therefore well away
from the Sulu Sea or the Celebes Sea proper. No island of such a
name, or of a name anything approaching it, appears on the chart of
the seas north of Borneo. Either, therefore, the original locality of
Mr. Thomson’s shells was incorrect, which there seems no reason to
believe, or the island has been wrongly located by succeeding writers.
What the island of “‘ New Beland’’ is, to which Mollendorff refers, and

470 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. [June 14,

June 14, 1892.
Prof. Flower, C.B., LL.D., F.R.S., President, in the Chair.

The Secretary read the following report on the additions to the
Society’s Menagerie during the month of May 1892 :—

The total number of registered additions to the Society’s Mena-
gerie during the month of May was 136, of which 80 were
by presentation. 20 by birth, 22 by purchase, and 14 on deposit. The
total number of departures during the same period, by death and
removals, was 75,

‘ Hypocolius ampelinus, 8 et 2.

Amongst the additions I may invite special attention to a pair of the
rare and beautiful Passerine bird the Grey Coly-Shrike (Zypocolius

1892.] MR. P. L. SCLATER ON CONTINENTAL MENAGERIES., 471

ampelinus) from Fao, Persian Gulf, presented by W. D. Cumming,
Esq., and received May 6th. We had previously received from the
same donor a male of this bird,which is still alive and in splendid condi-
tion. The drawing by Mr. Keulemans which I exhibit (see p. 470)
shows the attitude taken by the male of this species when courting.

Mr. Sclater made some remarks on the Zoological Gardens at
Rotterdam, the Hague, Amsterdam, and Antwerp, which he had
visited since the last meeting, and on the principal animals he had
noticed in each of them.

At Rotterdam was an example of an Antelope lately received
from the Congo, a male of Cephalolophus sylvicultor or of a nearly
allied species, believed to be the first example of this fine animal
brought to Europe. Besides this, the specimens of Tragelaphus
gratus and Cephalolophus badius (ef. P: Z. 8. 1891, p. 327) were still
living. In the Monkey-house were examples of Macacus ocreatus,
M. speciosus of Japan, and Semnopithecus pruinosus of Java. The
Zebras were represented by a pair of Hquus burchelli chapmanni.
Amongst the birds, Mr. Sclater had noticed examples of Gyps
rueppelli, Ketupa javanensis, a fine series of six Snowy Owls
(Nyctea nivea), Squatarola helvetica in full summer plumage, T'richo-
glossus forsteni of Sumbawa, Ardetta sinensis from Java, Plotus
anhinga (a fine adult -bird), and Gallinula orientalis from Java.

The Heronry in the Rotterdam Gardens (of wild herons, see
P. Z.S. 1891, p. 327) was in full vigour, there being 28 nests this
year, and a pair of Black Storks (Ciconia nigra) were nesting inside
the adjacent Night-Herons’ Aviary.

At the Hague Zoological Gardens the greatest attraction was the
large series of caged European Passeres, many Sylviide (e. g. Ruti-
cilla phenicurus, R. titys, Sylvia cinerea and S. curruca) being
amongst the number.

At Amsterdam the principal Antelopes noted were a pair of
Hippotragus equinus and a female of H. niger; a pair of Cobus
ellipsiprymnus and 3 males and a female of CO. defassa‘; also examples
of Gazella dama, of both species of Gnu, and of Bubalis albifrons.
The herd of Tragelaphus gratus was still flourishing, and consisted
of two males, two females, anda young male lately born. A Cephalo-
phus lately received from Western Africa appeared to be C. nigri-
frons. The Giraffes had become reduced in number to a single
female, but there were a fine pair of Mountain Zebras (Hquus zebra)
and a young one.

From the Zoological Gardens at Antwerp a number of desirable
acquisitions had been obtained for the Society’s Collection,
amongst which were examples of Casuarius uniappendiculatus, a
male Ostrich, and a pair of Victoria Crown- Pigeons (Goura victoria).
A young male Hippopotamus, born on the 6th September, 1891, the
fourth of the offspring of the adult pair now for several years in these
Gardens, seemed to be in splendid health and condition. It was
hoped that this animal might be acquired later on for the Society’s
Collection.

472 DR. J. ANDERSON ON SPALAX TYPHLUS. {June 14,

Mr. Sclater had also visited the private Menagerie of the Society’s
Corresponding Member, Mr. F. E. Blaauw, of Westerveld, s’Grave-
land, Hilversum, and admired the beautiful herd of White-tailed
Gnus, and the flocks of Rheas of both species (Rhea americana
and R. darwini) and the fine series of Water-fowl to be seen there.
A pair of Mantchurian Cranes (Grus viridirostris) were found engaged
on the duties of incubation, and both Bernicla poliocephala and
B. rubidiceps with young birds lately hatched *.

A communication was read from Mr. T. D. A. Cockerell, F.Z.S.,
of the Institute of Jamaica, containing an account of the occur-
rence of a specimen of the Jacana (Jacana spinosa, Cory, B. W. I.
p- 252)in Jamaica.

On April 20, 1892, Dr. Alex. G. McCatty, of Montego Bay,
Jamaica, had sent a specimen of this bird to Mr. F. Cundall, Secretary
of the Jamaica Institute, stating that it was quite new to him and had
been shot by his friend Mr. Dillon at Savanna-la-Mar, where it is
known to the people as the “ Bananaor Plantain Coot.” This was,
so far as Mr. Cockerell knew, the first certain record of the Jacana
in Jamaica. There was, however, in the Museum of the Institute
of Jamaica, a skin of a Jacana presented by Mr. H. O. Vickers in
1886, which was said to have been shot by that gentleman in West-
moreland Parish, Jamaica.

Ina subsequent letter (dated May 14th) Mr. Cockerell had written
as follows :— ;

“Since writing on this subject I have learned, from Mr. R. A.
Walcott, Resident Magistrate for Westmoreland, that the Jacana is
eertainly resident in Jamaica. It was first observed by a party of
gentlemen, of whom Mr. Walcott was one, in 1874, on the Cabaritta
River. Since then it has occurred regularly, being observed in the
Meylersfield Morasses, between Savanna-la-Mar and Little London,
along the banks of the Cabaritta, and at the ponds at Hodges, near
Black River, in St. Elizabeth. Although there is no history of its
importation, it seems probable that it must have been brought to
Jamaica from the mainland about 1873, as the rather numerous
sportsmen of Westmoreland and St. Elizabeth would surely have
observed it, had it existed there earlier. Its arrival by natural means
seems out of the question, as Mr. Walcott informs me that it cannot
fly long distances.”

Dr. J. Anderson, F.R.S., F.Z.S., read the following notes on the
occurrence of Spalax typhlus in Africa :—

“ Towards the end of last April, while in Lower Egypt, I found in
the district of Mariut, to the west of the great lake of the same name,
and about eight miles from Alexandria, the rodent exhibited to-night.

“TI may mention, in order to convey to you some idea of the cha-
racter of the Egyptian habitat of this animal, that unlike the delta

proper the Mariut district consists of low rounded hills, that form a
barrier between the lake and the sea. They are, however, ‘of no
great height, as the highest eminence does not rise probably more
than 80 feet above the sea-level. On the gentle slopes rising from
the lake, on the small plains, and in the hollows in the undulations,
the Bedouins who form the greater part of the sparse population
sow their crops, chiefly barley, trusting to the very meagre and
uncertain rainfall of winter and spring for the irrigation of the land.
If there is a moderate rainfall, the entire area, I am informed,
presents in spring a beautifully green and comparatively luxuriant
appearance, being covered with various flowering plants, among
which Asphodels and Hyacinths abound, and by the crops of the
Bedouins, which afford these people a fair return under such con-
ditions. However, I was not favoured with such a pleasing scene
during my visits, as everything was dried up, the rainfall of the past
winter and of this spring being remarkedly deficient.

‘**Qn my excursion we met an Arab working in his stunted barley-
field, and on questioning him about the different kinds of animals
found in the district, he mentioned one which he said was completely
blind and that burrowed on the higher ground and threw up mounds
of earth, the character of which he illustrated by taking a handful
of soil and dropping it into little heaps resembling mole-hills. I
was at first incredulous and told him that in order to convince me
of its presence it would be necessary for him to show me one, and
I promised him 10 francs for the first he should bring alive to
Alexandria. Two days afterwards he appeared at Abbatts Hotel
with one in a strong canvas bag, which when opened was found to
contain an animal certainly blind, as no external trace of eyes could
be detected, the area which the eye should have occupied being en-
tirely covered with skin and fur.

“ T appointed a day on which to return to Mariut, and arranged with
him that he should meet me near his village, and that we should dig
out the animal together, he having previously sought out a place in
which he had satisfied himself the animal was to be found.

“Qn meeting him on the day appointed, he led me to a little level
flat, on the upper margin of a barley-field, and approaching it care-
fully he stopped short and pointed out a small hole he had dug and
in which fresh earth had recently been thrown up, as if by a mole.
In making the hole he had cut through two of the passages of the
burrower, and he knew that in leaving them exposed the animal, if
it were in either of them, would close the one in which it happened
to be by throwing out earth, that would be more moist than the
surrounding soil and thus indicate its presence. Having thus
satisfied me that an animal was in this spot, he led me higher up to
another and still larger level expanse covered with little mounds
and with the dried stalks of Asphodels. Here, again, he had
taken the same precaution to find out the whereabouts of the
burrower. Selecting one passage we commenced to dig, but we
had not proceeded far when we found that it gave off secondary
tunnels, which had to be dug up to their blind extremities. As some
of these passages were nearly 30 to 40 yards long, the work of

474 DR. J. ANDERSON ON SPALAX TYPHLUS. [June 14,

opening them up occupied some time; but as the soil was not hard
and the tunnels not more than 18 inches, as a rule, below the sur-
face, the work was accomplished more quickly than it would have
been had the conditions been less favourable to digging. When a
secondary tunnel was encountered its opening was closed while the
main run was traced to its end, and then the secondary one was
taken up, and so on until at last all the runs were searched from the
points at which they had been cut across, and then the other sections
in the opposite directions were taken in hand. We followed some
of these to a depth of four feet, and there the passages were
numerous and some of them very short and running above others
below them. In one place, three runs were observed side by side,
but all ultimately diverged from each other. In following one of
these to the depth just mentioned we came upon a domical chamber
packed full of bulbs, some of which are exhibited. My wife counted
them as they were handed out and they reached the number of 68.
Adjoining this chamber was another, quite empty, and which the
Arabs said was the sleeping apartment. A passage leading off
from these chambers was followed up for a short distance, when
we came upon the animal moving backwards in it, retreating as we
gradually shortened its burrow, which proving to be a cul-de-sac
rendered the capture of the rodent an easy matter. All the passages
dug up seemed to radiate outwards from these chambers ; but. we did
not see any other store chambers, as the two other animals we captured
were found in runs near the surface. However, in following up one
animal we came upon a chamber the floor of which was covered with
a nest of leaves. The digging out of these three animals occupied
us four hours,

‘“* The tunnels are perfectly smooth and cylindrical, and in digging
through the soil above them numerous bulbs of the same kind as
those found in the store-house were observed. The runs are there-
fore tunnels made by the animal in search of its food.

“‘ I kept the three animals beside me for some time before sending
them off by steamer for London, placing each in a large tin box
half filled with earth and sand. I observed that when a number of
bulbs were given to them they manifested their hoarding instinct by
carrying them between their powerful teeth to one spot, where they
deposited them—a very striking performance in an animal devoid
of sight. The probability is that, in actions of this kind, it is
guided by the sense of smell, the other sense which is most developed
being that of hearing, even although there is no external ear, this
part of the acoustic organ being reduced to a tube beginning on a
level with the external skin, but of considerable capacity. The
animal is endowed with wonderful activity and is very restless at
night, thus still retaining a habit of life which, although probably
of no use to it now, is generally characteristic of its close allies. It
would be very interesting to know whether it ever comes above ground,
as the Arabs assert that males and females are never found in the same
burrows. The area, however, which I examined was so cut up by
runs from various centres that it is easy to conceive that the burrows of
different sexes occasionally intersect and communicate with one another.

1892.] DR. J. ANDERSON ON SPALAX TYPHLUS. 475

As an illustration of the energy of this animal and of the strength
resident in its neck-muscles and head, I may mention that one of
them forced open, during the night, one end of the overlapping lid
of the tin box in which it was confined, and escaped, even although
the lid was firmly tied down in the middle and was weighted above.
It achieved this feat by standing on its hind legs and by inserting
its broad spatulate head between the lid and the box. In the
morning it was found concealed between the folds of the cover of a
dressing-bag.

“The chief object of this note, however, is not to record the habits of
this remarkable animal, but to place on record its occurrence in Egypt.
It was known to Aristotle, and during the last two centuries it has
been described and figured by many naturalists. It is the only
representative of the genus Spalax, if these Egyptian individuals
prove to be the same as the European animal, which is found in
Poland, Southern Hungary, and Hastern Russia,indeed over nearly the
whole of South-eastern Europe, extending, as pointed out by Olivier
in the beginning of the present century, to Syria, Mesopotamia, and
Persia, and of late years found by Canon Tristram in Palestine as far
south as the neighbourhood of Jerusalem, and by Mr. H. C. Hart
at Gaza. If I have not overlooked any of the literature of this sub-
ject, it is now recorded for the first time from the African Continent.

“The Arabs know it as the dbu-amma. Abu means father, and
amma blind ; and I am informed that the two may be translated as
meaning the truly or essentially blind. In the specimens sent round,
the one in alcohol has the head intact, while in the other semi-dried
specimen the skin has been reflected to exhibit the small eye, a mere
black speck among the muscles, which Olivier states is perfectly
organized, but I have not as yet examined it myself. It will be
observed that the under surface of the reflected skin exhibits no trace
of the remains of an eye-opening, and that the eye is separated from the
skin proper by a thick layer of the skin-muscle, which I have partially
dissected out. The presence of this muscular layer must exclude
even the faintest sensation of light, so that, in time, all trace of an
eye will probably be lost if the animal retains its present habit of
using its head in burrowing, which is doubtless the cause of the
disappearance externally of the delicate organ of sight. Of course
its seemingly thoroughly underground habit of life also contributed
its influence in dwarfing the eye. The first instinct of the animal
when it is taken from its burrow and is let loose on the surface soil
is to dig its head into the earth, the transverse ridge on the bare
hard nose and the vibrissal ridge on the side of the head being special
modifications of structure depending on this habit of life. This
action of the large broad head is of course materially aided by the
fore feet ; but these structures are scarcely more developed than
those of a common rat of the dimensions of itself, and the claws
are only of moderate size.

** Spalax moves backwards in its burrows with remarkable ease,
as I observed in one of the specimens captured ; the reversible cha-
racter of the fur and the reduction of the tail to a mere rudiment
facilitate this movement.

476 MR. P. L, SCLATER ON DASYPELTIS SCABRA. [June 14,

“‘T had hoped to have shown to-night the animals I sent off alive
from Egypt, but they all died on the way home, the last off the Isle
of Wight. The person who was in charge of them informs me that
they would probably all have reached this country alive had not the
sandy earth that had been sent with them been impregnated with salt,
which began to deliquesce as soon as the ship got into the moist
atmosphere of the Mediterranean.”

Prof. Romanes gave an account of some results recently obtained
from the cross-breeding of Rats and Rabbits, and showed that
according to these experiments it did not follow that a blending of
the characters of the parents was always the result of crossing two
different varieties.

Prof. Howes exhibited and made remarks on some photographs
received from Prof. Parker, of Otago, New Zealand, illustrative of
Sea-Lions, Penguins, and Albatrosses in their native haunts.

Dr. Dawson made some remarks on the Fur-Seal of Alaska, and
exhibited a series of photographs illustrating the attitudes and
mode of life of these animals.

Mr. Sclater called attention to the habits of a South-African
Snake (Dasypeltis seabra), as exhibited by an example of this snake
presented to the Society’s Menagerie by Messrs. Herbert M. and
Claude Beddington, of Port Elizabeth, and received September 15,
1891, which was placed on the table.

As was well known, this snake fed exclusively on eggs ; and since
it had been in the Society’s Gardens it had occasionally eaten
pigeons’ eggs. These were, no doubt, pierced by the gular teeth
which this peculiar snake possesses, and their contents emptied
into the stomach.

A short time after the egg had been swallowed, the shell of the
egg was rejected from the mouth in the form of a pellet.

Specimens of these pellets were exhibited’.

1 Dr. Andrew Smith writes as follows :—

“The paucity and smallness of the teeth in the mouth are favourable to the
passage of the egg, and permit it to progress without injury, whereas were
they otherwise, many eggs, which have very thin shells, would be broken before
they entered the gullet, and the animal in consequence would be deprived of
its natural food when within its reach. Having observed that living specimens
which I kept in confinement always retained the egg stationary about two
inches behind the head, and while in that position used great efforts to crush it,
I killed one, and found the gular teeth at about the place where the egg ceases
to descend. Those teeth, I am satisfied from many observations, assist in
fixing the egg, and also in breaking the shell when the former reaches them, and
is subjected to compression by the muscular action of the parts surrounding it.
The instant the egg is broken by the exertions of the animal, the shell is
ejected from the mouth, and the fluid contents are conveyed onwards to the
stomach.” (‘Illustrations of Zoology of S. Africa,’ text to plate 73.)

Body-cavity of Snakes

1892. ] ON THE BODY-CAVITY IN SNAKES. 477

Mr. Sclater read some extracts from a letter addressed to him by
Mr. H. H. Johnston, C.B., F.Z.S., dated the Residency, Zomba,
British Central Africa, March 27th, 1892, announcing the despatch
of a large consignment of Natural History specimens illustrative of the
Fauna and Flora of the Shiré Highlands, a good proportion of which
were from altitudes of from 4000 to 8000 feet on Mount Zomba and
Mount Milanji. Mr. Johnston requested Mr. Sclater to place these
specimens in the hands of competent naturalists for examination.

Mr. Sclater stated that one box containing 150 bird-skins and
6 mammal-skins had already arrived, and that he proposed to ask
Mr. Oldfield Thomas to undertake the examination of the latter and
Captain Shelley to determine the birds. The first complete set
of everything was to be deposited in the British Museum.

Mr. W. Saville Kent, F.Z.S., exhibited and made remarks on
some photographs of a species of the genus Podargus (P. strigoides),
showing the strange attitudes of these birds in a living state.

Mr. J. W. Gregory, F.Z.S., gave an account of his researches on
the British Paleogene Bryozoa, of which he recognized 30 species,
represented in the National Collection by about 750 specimens.

478 MR. G. W. BUTLER ON THE [June 14,

§ I. Introductory.

This paper is a continuation of my previous one “ On the Sub-
division of the Body-cavity in Lizards, Crocodiles, and Birds”
(Proc. Zool. Soc. 1889, p. 452). Probably most persons will admit
that the comparative study of any structure is more or less useful,
since any such study may at any time suggest or confirm relationships
between different types, or may throw light on physiology. But
whether there be much or little interest in the relations (in the
different groups of the Amniota) of the pleuroperitoneal cavity, with
its more or less complete subdivision into different spaces, by
longitudinal, trausverse, or oblique membranes or ‘‘ diaphragms,”
the fact remains, that any departure from that which embryology
shows to be the simplest arrangement (viz. that seen in Lizards) at
once arrests the attention of the anatomist ; and, accordingly, much
is from time to time written on the subject.

Therefore, as the matter is one which cannot be satisfactorily
discussed except after somewhat laborious work in embryology and
comparative anatomy, I have thought it well, having once gone some
length in the matter, to continue my investigations.

I have to thank the “ British Association,” the occupation of
whose “ table’ at the Zoological Station at Naples in 1890 gave me
facilities for the collection of various Reptilian material, embryological
and otherwise, and also my former teacher Prof. G. B. Howes, of

placed at my disposal a large variety of Snakes, with permission to
work at them in his laboratory. I am also indebted to Mr. G. A.
Boulenger, who has kindly identified many of my specimens.

§ I]. Bibliography.

The writer in Bronn’s ‘ Klassen u. Ordnungen des Thierreichs’
(Band vi. Abth. 3, p. 1544) says :—“ The peritoneum of the Python,
and apparently of many exotic Snakes, exhibits peculiarities not
known in any other vertebrates. These peculiarities have been often
described, and always as something quite ‘new’ ”’; and he goes on to
give references. It would appear, however, from the way he speaks,
and the references he gives, that the ‘ peculiarities ” of which he is
thinking consist simply in the relation of the peritoneum to the
stomach and intestine, the individual coils of which latter it does
not follow. And, such being the case, he is quite right in saying
that they have often been described (at any rate from Meckel*
downwards). But this is only one point about the peritoneum of
Snakes, and not the most interesting one. While one of the authors
to whom he refers us [namely Retzius,(1) & (2)] has noted all
the other peculiarities, Duvernoy confines himself to the one point
above mentioned, and Herring, who is quoted without adverse

‘ Deutsches Archiv fiir die Physiologie (Halle), Band iii. 1817, p. 219.

criticism, is absolutely incorrect and misleading when he says of the
Boa constrictor, “ es ist kein Cavum thoracis oder abdominis vorhan-
den. ...”’; for the peritoneal cavity (‘‘ cavum abdominis ”) with its
various subdivisions, judging by a young specimen in the British
Museum, which, by the courtesy of Mr. Boulenger, I was permitted to
examine, is better seen in Boa constrictor than in most Snakes. It
is, however, hardly surprising that anyone, not forewarned by allied
studies, should err as to the peritoneum of these animals.

I shall notice the paper by Lataste and Blanchard presently.

We are also referred to F. Leydig [‘‘ Ueber die einheimischen
Schlangen,” Senckenberg. naturf. Gesellschaft, Band xii. 1883-4].
Leydig, however, like the writer in the ‘Thierreichs,’ who is
perhaps following him, quotes indiscriminately Herring, who is
wrong, and Retzius who is right ; and the conclusion which (oc. cit.
p- 214) he says we may draw from the various descriptions (as to
the coexistence of a peritoneal cavity and a subdivided lymph-space)
is, as might be expected, vague, and does not convey a correct idea
of the actual facts.

To one who has elsewhere found nothing but incomplete and
usually very meagre and general, if not incorrect, accounts of the
Ophidian peritoneum, it is a pleasure to turn to the account of
Retzius (1) & (2).

This author in 1830 described the state of things in the Python,
overlooking no division of the peritoneal cavity ; though in the case
of two of the smaller spaces he simply calls them “ serous canals.”
His description of the peritoneum appears to be as complete as it is
possible for such a description of the anatomical features of any one
animal to be, without the light thrown by comparative anatomy and
development. One small division of the peritoneal cavity, which
embryology shows to be a remnant of the ‘‘omental” space, I did
not myself discover in any adult Snake until after reading Retzius’
account of the Python. But although this careful “old master ”
seems to have seen more than any one else since, I nevertheless hope
that there will be something “ new”’ in the following paper, in so far
as a study of their mode of origin furnishes material for the discussion
of the true nature and the homologies of the various peritoneal
spaces, and in so far as a comparative study of examples of nearly
all the families of Snakes enables me to state it as probable
that most, if not all Snakes, while differing considerably in other
respects, are essentially alike in their peritoneal cavities ’.

We come now to the papers by Lataste and Blanchard (3) and
Blanchard (4). The statement on p. 95 of (3), to the effect that
the peritoneum does not extend anteriorly to the gall-bladder, is
qualified by one on p. 106, to the effect that there are two serous

1 For instance, Zupinambis (Tejus) differs strikingly from other Lizards in
the possession of a most distinct transverse septum behind the liver (see Proc.
Zool. Soc. 1889, piate xlviii. and text). I have recently discovered a previous
mention of this structure by Meckel [Deutsches Archiv fiir die Physiologie
(Halle), Band iii. 1817, p. 218]. However, Meckel gave no figure or detailed
description of this septum.

sacs in the region of the liver. These authors are chiefly concerned
with details as to the most posterior of the spaces described in this
paper, especially as to its tapering forward and backward extensions.
Some of their statements were in 1880 questioned by S. Jourdain’ ;
and in 1882 Blanchard, in the light of new material, published a
second paper (4) in which he modifies the account given in the
former (3) *.

These authors refer us to Cuvier (1835), Duméril and Bibron
(1844), Siebold and Stannius (1848), and Milne-Edwards. I have
of course carefully consulted these and also Owen, Hunter (‘ Essays
and Observations,’ edited by Owen), and various modern text-
books ; but I have not found anything on this subject to which it is
worth while to refer the reader. Anatomists have as a rule kept clear
of it; and one feels that it would be often mere impertinence to
criticise in detail the little that has been said. So far as my search
has gone, while here and there we find details of truth often mixed
with more or less error, it may be said, speaking generally, that
those authors who are not betrayed into including Snakes under
their description of other reptiles, keep safe, by confining themselves
to the most meagre details or to the most vague and general
statements. For instance, Cuvier (Lecons d’ Anat. Comp. 2nd ed.
1835, tom. iv. 2° part. pp. 670, 671) describes the relations of
the pleuro-peritoneum in the Slowworm (Anguis fragilis), where we
have the typical Lacertilian condition, and adds that in the true
Snakes things are similar, but more complicated. In the paper
above referred to (3) Lataste and Blanchard do an injustice to
Cuvier by quoting this passage without the last ‘ saving clause.”

2 What chiefly interests these writers is a macroscopic connection which they
find between the hinder division of the peritoneal cavity and the connective
tissue in that region, and so possibly with the “cisterna magna” (grande
cisterne rétro-péritonale), and they add suggestive remarks as to the relations
of ceelom, lymph-spaces, and connective tissue in general, and the inter-
changeability of the two latter. There is, as they say, nothing essentially new
involved, but it would be interesting, if their account be correct (but this is
disputed), to see with the naked eye what is in other animals only to be seen
with the microscope.

Lizards, Anguis fragilis, Chalcides mionecton, and apparently Acontias mono-
dactyla have their “ pulmohepatic recess” not extending into the region of the
lungs. So that a section through the lungs resembles fig. B on that page, and
one behind the lungs shows the right lobe of the liver attached as in fig. A.

SIV. On the Subdivision of the Body-cavity in the Adult Snake.

(0). Preliminary, and as to certain Extra-peritoneal
Lymph-spaces.

Once one kuows what to look for and where to find it, it is not
difficult to make out the relations of the peritoneum,in Snakes of
ordinary size, such as the Common Grass-Snake (T'ropidonotus natria)
or the Common Viper (Vipera berus). But without such knowledge
it is, judging by my own experience, not so easy.

I may perhaps be excused then if, in describing what is seen, I
explain how to find it. I have spoken simply of the peritoneum,
because, as may with advantage be stated here, the pleural cavity
or cavities appear to be obliterated in all the Snakes I have examined
[this will be discussed later, § VI.]. All my specimens have been
more or less hardened in spirits, and it would seem that sometimes
specimens which on the outside appear unduly soft are well adapted
to our present purpose.

To dissect a Snake, insert scissors between the skin and the ribs,
and cut all along the body from the region of the heart to the
cloaca, keeping rather to one side of the mid-ventral line, with the
scissor-points close under the skin. Having then turned back the
skin from the ventral side of the animal, nothing is simpler than to
ease away outwards on each side the ribs and the muscles of the
body-wall, so far as they close in the ventral side. We then see,
stretching from about the hinder end of the liver to not far from
the cloaca, the well-known fat-bodies, sheathed ventrally by mem-
branous tissue, which laterally wraps round outside all the viscera
including the kidneys.

Now, first, as to these fat-bodies. If the Snake under examination
be a Python or a Cylindrophis rufa (and I think I might add the

1892. ] BODY-CAVITY IN SNAKES. 483

water-snakes Hydrophis and Pelamis), one possible source of error
is eliminated, for in these there is no space round the fat, such as is
present in the great majority of Snakes. In Python the fat occurs
as a number of small separate lobules, quilted between membranous
tissue, and the condition is somewhat similar in Cylindrophis, though
anteriorly the fat-lobules tend to run together.

On the other hand, in most Snakes the fat occurs as a continuous,
but often much folded band on either side, each of which hangs in
a well-marked lymph-cavity ' which might perhaps be taken, as it
has been taken in certain other Reptiles, for a part of the coelom
proper. Development, however, shows that this is not the case. The
fat and the space round it become differentiated at a comparatively
late embryonic stage, and the space probably arises in the same way
as, and should be placed in the same category with, the “ cisterna
magna,” in which runs the aorta*. This latter is, like the cireum-
adiposal lymph-spaces, well developed in Snakes. Besides these
there may be a more or less distinct lymph-space round the kidneys.

Tt would have been impossible, in discussing the body-cavity
proper of Snakes, to omit a reference to these extra-peritoneal lymph-
spaces, for they are certain to strike the observer, and may be in
some cases more conspicuous than the peritoneal cavity itself; and
he might possibly take them for part of this and wonder why no
reference had been made to them. For further remarks on these
spaces, and figures showing their relations in adult T'ropidonotus and
Vipera aud advanced embryo of Zropidonotus, see paper “ On the
Relations of the Fat-bodies of the Sauropsida.” *

After opening the ventral body-wall of the Snake as described
above, it will be best, before further dissecting, to ascertain the
position of the right and most anteriorly situated kidney. If,
then, we cut through the membrane ventrad of the fat a little
to the right side of the animal, we, as explained above, in nearly all
Snakes cut into the right circumadiposal space; this can be
followed forwards and backwards, as a continuous space from one
end of the fat to the other. If we next, turning up the fat, cut
through the inner membranous wall of this space at a point just
anterior to the right kidney * we shall have cut into :—

SIV. (i.). The Single Posterior Peritoneal Space.
This is described by Retzius, (1) p. 91, (2) p. 517, and Lataste

1 Tn certain other Snakes we see a condition of things intermediate between
this and what obtains in Pythons—in fact, we have an interesting and possibly
suggestive series, which need not, however, be discussed here,

2 Thus in advanced Hlaphis embryos (Plate XXVIII. figs. A, B) the allantoic
arteries run forwards from the aorta to the umbilical stalk in the posterior part
of these cireumadiposal lymph-spaces, as the aorta runs in the cisterna magna,
but there does not appear to be any communication between these spaces.

and re in figs. 5 and 6 should be ¢.w.]

4 Tf we cut at random we shall possibly miss the peritoneal cavity alto-
gether, and may perhaps cut either into the ‘cisterna magna,” or a lymph-
space that may surround the kidney.

484 MR. G. W. BUTLER ON THE {June 14,

and Blanchard (3). If we carefully, with the aid of a seeker and
pair of scissors, open up the ventral wall of this space, we shall find
that it tapers off posteriorly on the ventral side of the rectum and
appears to end at a small distance in front of the cloaca (varying in
different species). On the other hand, we find that it ends anteriorly
in front of the reproductive glands. It is in fact, like the corre-
sponding space in Birds, Crocodiles, and Tupinambis, an intestino-
genital cavity.

As the right reproductive gland lies, in Snakes, in advance of the
left, this posterior peritoneal space extends forwards farther on the
right side than on the other.

In the male we shall probably have no difficulty in making out
the anterior limits of this space, just in front of the anteriorly
rounded testes.

But in the female it may not be always easy to say exactly where
this space does end anteriorly. If we follow the oviduct of either
side forwards, we find the anterior end of its funnel continued as a
thread into a narrow, forwardly directed, funnel of peritoneum. On
the right side [¢f. (3) pp. 100, 101] this narrow peritoneal funnel or
tube runs forwards just externally to the portal and postcaval veins,
and is the remnant, as will be explained later, of the right half of the
peritoneal cavity in this region, which, down to a comparatively late
embryonic stage, persists as a narrow tube (fig. 3°, P®) placing the
posterior peritoneal space now described in communication with
that in which the right lobe of the liver lies. Similarly with the
small funnel on the left side. We can frequently tell approximately
where these peritoneal tubes or funnels end, and this was especially
clear in a specimen of Heterodon dorbignii. While sometimes it
is hard to say this, it is not very important to know the exact
point at which such tapering tubes end, especially as it is, in nearly
all cases, perfectly clear that the anterior peritoneal spaces into
which they might be expected to lead are closed behind’. ‘The
wonder is not that where, as in the females, these forwardly directed
peritoneal funnels occur they should vary as to their extension
forwards, but that the original embryonic continuity of the peritoneal
cavity on either side is, so far as I can ascertain, never maintained in
the adult.

Before leaving this hindmost division of the peritoneal cavity,
which, as stated, extends in the male (and except for insignificant
tubular processes in the female also) from the anterior border of the
reproductive organs to a point on the rectum usually not far from
the cloaca, it may be well to say a few words as to the viscera which
project into it.

As stated in § IL, the relations of the peritoneum to the alimen-
tary canal have been repeatedly noticed by writers on Suakes, from
Meckel (loc. cit.) to the present day (cf. for instance Rolleston,

1 It is only rarely that the right half of the liver tapers off backwards
along the course of the posterior vena cava. When this is so, it may be some-
times difficult to say exactly where the tapering liver-sac ends, [Liophis
meremtt, Vipera arietans, V, nasicornis, Crotalus durissus, |

1892. ] BODY-CAVITY IN SNAKES. 485

‘Forms of Animal Life,’ 2nd ed. p. 69). From my tabulated
notes I find that the straight terminal portion of the intestine seldom
projects at all into the body-cavity, and that the less folded portion,
immediately preceding this, seldom (as in Cclopeltis lacertina,
Crotalus durissus, Compsosoma melanurum, and Python) has any-
thing that can be called a mesentery. As to the zigzag part of the
intestine that follows the stomach, the peritoneum (as so often
noticed) does not follow the individual bends, but merely covers the
zigzag as a whole. In fact the intestine of Snakes, as a rule,
intrudes upon the peritoneal cavity less than in any other Vertebrates.

Secondly, as to the kidneys*. With rare exceptions, the permanent
kidneys in Sauropsida (unlike the Wolffian bodies of the embryo,
and the kidneys of certain Mammalia) do not project freely into the
body-cavity, but are in great part, if not entirely, situated out-
side it*. Snakes are no exception to this rule. In Boa constrictor,
it is true, I have found the kidneys hanging freely in the body- cavity,
as in certain Amphisbeenidz, but this is the only case I have
found among Snakes. The only other Snakes in which I have found
any part of the kidneys projecting into the body-cavity are Typhlops,
Celopeltis, and the Pythonide, and in these cases the intrusion is
but slight. In all the other forms examined (see list § III.)* the
kidneys lie entirely outside the peritoneal cavity, and do not project
at all into it. It is interesting to note that this exclusion of the
kidneys from the body-cavity in Snakes is, like the absence of this
cavity round parts of the alimentary canal, not primary. That is to
say, when, at a comparatively late embryonic stage, the permanent
kidneys first begin to develop, they in part project into the
peritoneal cavity, as is the case in the adults of some (and perhaps
most) Lizards.

Thirdly, the only other organs whose relations to this hinder
peritoneal space we have to consider are the reproductive ones;
and these in both sexes (and as I believe to be the case in all Verte-
brates) project freely into the body-cavity.

Bearing, then, in mind that the kidneys of Snakes are with rare
exceptions wholly outside the peritoneal cavity*, and that the
intestine commonly has no mesentery and bulges but little into the
body-cavity, so as in individuals of some species (Liophis meremii)
to appear to have almost entirely receded from it, it will be readily
understood that this hinder peritoneal space may occasionally
be reduced in Snakes to little more than a tube containing the

' I add these remarks as to the kidneys because those organs are usually
referred to in discussing the relations of the peritoneum, and the impression is
sometimes conveyed that there is something unusual in the exclusion of the
kidneys from the body-cavity.

2 The Amphisbenide [e. g. 4. darwinii, Lepidosternon scutigerwm, and to a
rather less extent 4. alba and Pachycalamus brevis] are the only marked
exceptions I know of besides the Boa constrictor.

$ I could not ascertain the relations in Lamprophys, Hydrophis, and Crotalus,
but have no reason to suspect them to be exceptional.

+ The lymph-space mentioned above which may occur round them must not
be mistaken for part of the peritoneal cavity.

reproductive glands and their ducts. From this it is not surprising
to find that it terminates anteriorly in front of the reproductive

organs, the body-cavity of either side being obliterated over a longer
or shorter area.

§ IV. Gi). The Unpaired “ Gastric”? Peritoneal
Space of the Left Side.

Between the hinder end of the right liver-lobe and the anterior
end of the right reproductive gland the main’ right half of the
peritoneal cavity is unrepresented in the male ; and in the female itis
only represented (as described above) by a narrow peritoneal funnel
or tube which sometimes extends but little in advance of the ovary.

On the other hand, on the /ef¢ side there is, with few exceptions, a
distinct peritoneal space to be made out in the pyloric region.
Retzius [(1) p. 89, and (2) p. 515], describing Python bivittatus,
notices both this and the space which will be later referred to
[§ LV. (iv.)] as the omental one.

To find this gastric space in any Snake, we, after the preliminary
easing away of the body-wall described above (§ IV. (0)), mark the
point at the end of the stomach where, about opposite the hind end
of the gall-bladder, it is often slightly bent (just where its thick-
walled part ends). Then, carefully lifting up and cutting through
the membranous tissue that wraps round the left and ventral sides
of the posterior end of the stomach, we shall in nearly all cases
(see § III. and § V.) find a distinct serous space, which, in the region
described, wraps round the stomach on its ventral and left sides
(the “blind sac” of Retzius); when, as sometimes happens, this
is continued forwards by a narrow canal (‘left serous canal” of
Retzius), this latter, as a rule, lies more ventrally than laterally
to the stomach itself.

This gastric sac was, among the forms I examined, best developed
in a specimen of Celopeltis lacertina, where it extended from a
point 14 inches behind the gall-bladder forwards, so as to slightly.
overlap the left liver-lobe. It is, however, here, as apparently in all
Snakes, divided off from the peritoneal sac that surrounds that liver-
lobe. It is also well developed in some specimens of Zamenis
gemonensis (a common Italian Snake) and in the various types of
Pythonide examined (viz. Hryw, Enygrus, Python). It was also
distinct in Compsosoma and Lamprophis; and in fact I ascertained its
presence in all the species examined, with the exception of a few
marked (c) on the list in § ITI., and it not improbably occurs in some
of these also.

However, it is developed to a very different degree in different
species and in different individuals of the same species. Thus it
will very likely not be found in many specimens of Tropidonotus
natrix, while it would appear (Elaphis, Zamenis) that it may be larger
in the male than in the female.

1 There is, however, in many cases, a more or less marked “omental” space
traceable (cf. $IV.).

1892.] BODY-CAVITY IN SNAKES. 487

As might be expected, when this “ gastric’’ sae is reduced in
extent, what remains of it will be found at the point where it is most
expanded in other cases: that is, at that point approximate to the
posterior end of the stomach, where I have suggested above that
search for it should be made.

§ IV. (iii.). The Paired Peritoneal Liver-sacs.

Some writers make a point of the liver of Snakes being unilobular.
This is in a sense true, in so far as, with the exception of the oft-
quoted liver of Typhlops [in which animal there are some three
principal, besides minor, lobulations of the liver on each side], and the
trifling lobulation that may be seen in some other cases (Vipera
berus and arietans), the liver of Snakes presents at first sight the
appearance of one elongated body.

However, morphologically, no animal has a more obviously
bilobed liver. And it is most certainly incorrect to say, in the
language of one of our text-books, that the liver of Snakes cor-
responds only to the right liver-lobe of other Reptiles.

As Retzius remarks of the Python [(1) p. 96, (2) p. 520], the diver
is divided “into a right and left half... each lateral half of the
liver is enclosed in a serous capsule of its own.”

It need perhaps hardly be added that the dorsal and ventral lines
of demarcation between the two halves of the liver really represent the
lines along which that organ meets the median longitudinal septum,
which in its dorsal part supports the cesophagus and which, in all
air-breathers, divides the pulmohepatic part of the pleuroperitoneal
cavity into right and left halves’. We shall return later, § VIL., to
these liver-sacs, so that little need be said of themhere. They fit the
liver-lobes pretty closely, and therefore cannot possibly be missed
even in the smallest Snakes.

In the rare cases in which the right liver-lobe tapers off along
the course of the posterior vena cava (Liophis meremii, Vipera
arietans and nasicornis, and Crotalus durissus), the liver-sac of that
side necessarily does so too, wherefore it is hard to ascertain exactly
where it ends.

§ IV. (iv.). The Unpaired “ Omental”’ or “ Lesser Peritoneal”
Space of the Right Side”.

This space is practically the most difficult of any of the peritoneal
spaces to find. Moreover, I do not think that it is present in the

1 Owing to the marked tilting of the liver over to the right side in Snakes,
while the right, and usualiy only, lung often takes upa position in the mid-
dorsal line, what is morphologically the median sagittal plane of the Snake,
so far as the celom and viscera are concerned, usually, in the region of the
liver, makes an angle (varying from 45° [¢f. Plate XXVIII. fig. 2*] to 90°) with
the plane joining the vertebral column with the middle of the ventral scales.

? The space referred to occurs apparently in all the Amniota, and it is, I

485 MR. G, W. BUTLER ON THE [June 14,

adults of all Snakes; and this, not merely because I have not in a
number of cases been able to satisfy myself as to its presence by
dissection, but also because in Elaphis quadrilineatus, of which I
obtained some advanced embryos, I find, by serial sections, that it
is almost totally obliterated while still within the egg.

If this space is present, one may expect to find it as a small one
immediately on the right side of the stomach, and especially of the
hinder part thereof—in fact, lying between the gall-bladder and the
stomach and bounded behind by the pancreas. It will not in any
case extend caudad of the pancreas, and it may not reach quite so
far back as the anterior end of that organ in the adult. Anteriorly
it may, when specially well developed, extend forwards as a narrow
space on the right side of the stomach to a point a little anterior to
the posterior end of the right liver-lobe (Typhlops lumbricalis).
This omental space, in the Snakes which I have examined, is best
seen in Z'yphlops, Xenopeltis, and the Pythonide; it is also well
marked, though in a less degree conspicuous, in Compsosoma, Den-
drophis, and others. I could not distinctly make it out in the forms
marked (4) and (ce) in the list (p. 489).

This ‘‘ omental” space must not be confused with the “ gastric ”
space above described, which runs close to it but more to the left
side; that, in its hinder region, usually distinctly wraps round the
left side of the pyloric part of the stomach, while this omental space
is on its right side.

believe, disguised, by the fenestration of the mesogastric and gastrohepatic
ligaments, in the Amphibia also.

The word “ omental” is somewhat ambiguous, and “ /esser peritoneal cavity,”
though excellent for the Mammalia, is unsatisfactory in the case of Birds,
Crocodiles, and Snakes, where there is more than one such cavity present.

Tt may be explained, then, that the term “ omental space” is here used to
include the whole space that corresponds to (a) the “Saccus omenti” of
Mammals (the sac enclosed by the recurved stomach and its attached membranes),
and (6) the “Recessus superior sacci omenti” of His, which in embryos of
Mammals extends forwards into the pulmonary region, and is the right
“ pulmohepatic recess” of my previous paper (5). In Lizards, Crocodiles, and
Birds this “ recess” may be more important than the “ saccus ” itself.

In the adults of most Lizards, of certain Chelonians (Zhalassochelys), and
at any rate of certain Mammals, and in the embryonic stages of Crocodiles,
Snakes, and Birds, we find that this “ omental space” communicates with the
right side of the peritoneal cavity by an aperture (very wide in many Lizards)
which is the “ Foramen of Winslow.” This “ Foramen of Winslow ” is bounded
postero-ventrally by the pancreas and the hepatic duets, which run in the hinder
margin of the gastro-hepatic ligament, and antero-dorsally by the posterior vena
cava, which, in its course from the kidneys (or in an embryo from the Wolffian
bodies) to the liver, runs in what either is, or once was, the posterior margin of
a ligament attaching the right half of the liver to the dorsal body-wall.

This ‘“ Foramen of Winslow” may persist as described, as in most Lizards
and some Chelonians (Thalassochelys) and Mammals ; or it may become oblite-
rated, as in Amphisbznians, certain Chelonians (Zestudo and Emys), Snakes,
Crocodiles, and Birds (Gallus).

‘In the latter case we have, as a result, an entirely closed peritoneal sac.

T indicates that a Snake probably has a “ gastric” sac.

1— Typhlops.—In this the anterior and posterior boundaries of the gastric
sac were not clearly made out.

2—Dryophis (one of the long “ Whip Snakes ”’).—I cannot pretend to have
seen the posterior boundary of the liver-sacs, but have no reason to
believe that they are not closed as in all other cases.

3—Lamprophis.—tit is possible that the right testis is enclosed in a separate
peritoneal sac apart from the posterior peritoneal space. If so, this
would be a peculiarity of this Snake.

4—Vipera nasicornis—I am not sure that the gastric sac does not com-
municate with the posterior peritoneal space. If it does, we merely
have a persistence of acondition of things which (sce § VI.) certainly
does persist to a comparatively late embryonic stage.

”

The list in § III. in part speaks for itself. I may point out,
however, that Snakes marked b and c are essentially similar as to the
relations of their peritoneum to those marked a. The “gastric”
and still more the “ omental” space is as a rule small, and anyone
who did not know exactly where to look for either would in most
cases not find them. Where there was no clear indication of one or
both, I have marked the Snakes 4 or ¢ as explained ; and it is quite
possible that one or both of them may be found in Snakes so marked.
Moreover, even if they are absent this does not indicate any hard-
and-fast dissimilarity between the Snakes marked } and ¢ and those
marked a, for development (§ VI.) shows that both the “ gastric”
and the “ omental” spaces are, with rare exceptions, but reduced
remnants of original more extensive ones; and a comparative
study of the Snakes on the list shows that when these spaces are
present, the amount of reduction of either varies very greatly, not
only in different species but in different individuals of the same
species. It is not then surprising, but, rather, just what we
should expect, that in some cases one or both of these spaces should
have become obliterated altogether.

§ VI. The Developmental History of the Pleuroperitoneal Cavity
of Snakes.

At first sight the aspect of a Snake embryo is perhaps forbidding
to the embryologist*. During much of its early existence great
part of such a Snake is coiled round its allantoic stalk in such a way
that it cannot be uncoiled, and one may have to do with the same
embryo cut through nine times in one section. On the other hand,
in later stages, when the embryo can be straightened out, it is apt to
be desperately long. However, the part of the animal which chiefly
concerns us in the earlier stages is not affected by the coiling, and
though the modifications which produce the characteristic relations
of the peritoneum of the adult Snake only arise at a comparatively
late embryonic stage, one comes to the end of even a six-inch Snake
sooner than might be expected, especially when, as in the present
case, it is not necessary that the sections should be very thin.

§ VI. (i.). Barly Embryos of Tropidonotus, Zamenis, and Vipera
(with gill-slits).

For the earlier stages (about period II. of Rathke’), I obtained a
series of embryos of Vropidonotus natriz, and a less complete one of
Zamenis gemonensis and Vipera aspis. These stages extend from (i)
a time, soon after the first appearance of the allantois, when there
were traces of but one or two postoral clefts and the spiral coiling
had not begun, to (ii) a time when there were 4 complete coils in
the abdomino-caudal region, and when, though the gills were hardly
so apparent as in a stage with only 3 coils, sections showed that
there were here, as in that stage, 4 pairs of postoral gill-pouches, the
first two of which communicated with the exterior.

In the most advanced of these earlier stages the plewroperitoneal
cavity presents a condition of things similar to that which we find
in Inzards. That is to say, besides the main pleuroperitoneal cavity
continuous throughout its whole extent, we have to the right of the
stomach a “lesser peritoneal” or “ omental ” cavity, communicating
with the right half of the main pleuroperitoneal one by a “ Foramen
of Winslow.”

The omental sac proper is, however, very small. Its anterior
recess [‘‘ Recessus superior sacci omenti”” of His—my “ pulmo-
hepatic recess ” (5)], which, in Birds, Crocodiles, Cheionia, and most
Lizards, runs forwards between, and is bounded by, the cesophagus
and the lung and liver-lobe of the right side, and their connecting
ligaments), in these Snake embryos, as in certain Scincoid Lizards *,

’ On the supposition that he desires to obtain a complete series of sections.
Doubtless much can be done without this, but in dealing with a subject like that
before us, when microscopic spaces have to be traced and it is often desirable
to be able to prove a negative—to prove, for instance, that two small spaces do
not communicate—no other method is equally satisfactory.

does not extend forwards into the region of the lung’; it is confined
to the hepatic region—the pancreas, which forms the posterior wall of
the space, being, together with the gall-bladder, at this stage and for
some time longer in contact with the liver. But as development
proceeds, and as the lung extends back to and beyond the hinder
end of the liver, and as the pancreas and gall-bladder come to lie, as
they almost invariably do in Snakes, a considerable distance behind
the liver’, this space (if not obliterated) comes to be, with rare
exceptions, entirely posthepatic in position.

§ VI. (ii.). Lméryos of Elaphis quadrilineatus, 11 cm. long.

The next stage that I have, an Hlaphis embryo 11 em. long
(Plate XXVIII. fig. A), (all allowance being made for Elaphis beg
a larger Snake than Tropidonotus or Zamenis, with larger eggs), is
considerably more advanced than the stage just described, and yet for
our present purpose there is no important gap between them. ‘There
is in fact, as far as the pleuroperitoneal cavity is concerned, at first
sight as yet nothing to suggest the characteristic Ophidian condition.
The liver-lobe of either side and the lung for the greater part of its
length project freely into the common pleuroperitoneal cavity.

The only definite change that we have to note is the closing of the
“*Foramen of Winslow”; this, however, not only occurs in Birds
(Gallus), Crocodiles, and many Chelonians, but also in the snake-like
but truly lacertilian Amphisbenidee. In fact an Elaphis embryo of
ll em. long is still lacertilian as to its pleuroperitoneal cavity ; but,
nevertheless, the changes that are shortly to supervene are fore-
shadowed.

Lizards, and perhaps little importance is to be attached to the difference.
Whichever is the more primitive state of things, the one may easily be derived
from the other. The condition in Snakes and the Scincoids first mentioned is
probably associated with the elongation of form, and with the origin of the
liver at some distance behind the point of origin of the lungs. In fact, in these
Lizards, as in all the Snakes I have examined (with the exception of the species
of Vipera, Hydrophis, Pelamis, and less markedly of Typhlops), there is even in
the adult a distinct gap between the anterior end of the liver and the heart.

1 Some of the Snakes examined (sce list, p. 481), viz. the Pythonide (Ery2,
Enygrus, Python) and Xenopeltis, have two well-developed lungs, the right,
however, being the larger. Others, viz. Rhinophis, Cylindrophis, Aspidura,
Elaps, have a more or less distinct rudiment of a left lung. Others again—
Tropidonotus, Elaphis, Dipsas—have the merest trace of this, only to be found
by careful search near the posterior corner of the heart. In some, again,
Vipera (berus and aspis), Crotalus, Lamprophis, and others, I did not find any
trace of a left lung. In Vipera aspis I find no trace of a left lung even in early
embryos. Though I have no embryonic stages of the Pythonidz or Xenopeltide,
a comparison of their anatomy with that of the more usual one-lunged forms
seems to assure us that, for our present purpose, there is no noteworthy difference
between them. The left lung, when present, lies between the dorso-lateral wall
of the left liver-sac and the cesophagus, in a position, in fact, corresponding to
that of the right lung of the other side, and has not, any more than its fellow,
any trace of pleural cavity round it.

* However, in Rhinophis and certain specimens of Aspidura the gall-bladder
is close to the liver, and it is not far removed in the Common Viper (Vipera
berus).

492 MR. G. W. BUTLER ON THE [June 14,

Thus, considering the relations of the lung to the body-cavity,
we find that in the region anterior to the liver the cavity is reduced ;
and, tracing our sections backwards, we find that the anterior part
of the lung is surrounded on all sides by connective tissue. Then
(still in the region of the heart) a small cavity appears on the outer
side of the lung, which (P? in fig. 1“), as we approach the apex of
the heart and the anterior border of the liver, extends round dorsad
of that organ. In sections that pass through the anterior apex
of the liver, the lung is bounded ventrally by a sort of incipient
fibrous-tissue ‘‘ diaphragm,” referable in part to a latero-anterior
ligament of the liver, and in part toa proliferation of connective
tissue that occurs on the ventral side of the lung, which we can
trace extending backwards over the ventral surface of its at present
free portion (* in fig. 2“).

As remarked above, transverse sections taken anywhere else through
the liver show the lung projecting freely into the common pleuro-
peritoneal cavity, which wraps round it dorsally and ventrally, in
fact all round it, except on its left or mesial side where it is attached
(fig. 2"). When, however, we follow the sections still farther back,
behind the liver, we find that the posterior part of the lung burrows
as it were into the connective tissue dorsad of the body-cavity, a
little to the right of the aorta (fig. 34).

We see, then, that at both ends there is a tendency to exclude the
lung from the general body-cavity, and at the same time to obliterate
the pleural cavity. Similarly, if, leaving the lung, we turn to the
left side of this embryo and follow the sections backwards, we find
that it is not till we reach about the middle of the liver that we see
the cesophagus projecting into the peritoneal cavity. For the
anterior part of its course it is for the most part surrounded by
connective tissue (figs. 1“ and 2*).

Again ; on the same left side of the body, just posterior to the left
lobe of the liver, we find a foreshadowing of the “ posthepatic
septum,” which later closes the liver-sacs posteriorly. This fore-
shadowing consists in a broadening and leftward extension over the
stomach of the median ventral ligament. We note also that behind
the liver the body-cavity of either side is somewhat circumscribed
(fig. 3*).

§ VI. (ii.). Embryo of Elaphis quadrilineatus, 15 em. long.

My next stage is an Elaphis embryo 15 em. long (Plate XXVIII.
fig. B). LIregret not having a stage intermediate between this and the
preceding, or any embryo of another species of equivalent age. Still,
I think that a careful comparison of the 11 cm. and 15 cm. stages
leaves but little uncertainty as to how we ought to regard these peri-
toneal spaces of Snakes.

Comparing the general features of the two embryos, we see that
the head has now a less embryonic appearance, the lower jaw, for
instance, being better developed. The umbilicus is further removed
from the cloaca, and sections show us that the gall-bladder and

1892.] BODY-CAVITY IN SNAKES. 493

pancreas have become separated from the liver, and that the lung has
grown a considerable distance backwards. In fact, an embryo of this
stage, but for its comparative stoutness and the persistence of the
Wolffian bodies in front of the kidneys, is very similar to the adult
in the proportion of its parts and the position of the viscera. It is
curious that the liver does not seem to have grown in length pro-
portionate to the rest of the body.

Turning now to the condition of the body-cavity, we find that in
the Hlaphis embryo, 15 cm. long, the lung has become entirely
excluded from that cavity, or, rather, that part of the body-cavity
which in the 11 em. stage extended round the outer and dorsal
walls of the lung has been entirely obliterated (figs. 28, 3°).
Remembering, however, that in the 11 cm. stage it was only the
part of the lung in the region of the liver (at that time the greater
part of the lung) which projected freely into the body-cavity, it will
not surprise us so much as it might otherwise do to find that no
part of the lung is now surrounded by that space.

It will be remembered that, anterior to the liver, the pleural
portion of the ccelom was in the preceding stage already in great
part obliterated (fig. 1); and, judging by the relations of the poste-
rior end of the lung at that time (fig. 3*), it is but natural to conclude
that the great length of lung which now extends behind the liver
(cf. figs. B and 3%) has developed where we find it, by burrowing
backwards as it were in the fibrous tissue dorsad of the peritoneal
cavity. We have, then, only to account for the exclusion from the
body-cavity of that part of the lung which lies in the hepatic region
(compare figs. 2“ and 2%).

Now, in the 11 em. stage there was as described a considerable
development of fibrous connective tissue, both on the ventral and
dorsal free surfaces of the lung (fig. 2*, **’) ; and the idea naturally
suggests itself that, as far as that part of the lung which lies in the
region of the liver is concerned, the fibrous tissue ventral to the
lung [working backwards and forwards from the points opposite the
anterior and posterior ends of the liver (cf. figs. 1* and 3“), where we
saw the lung in the 11 em. stage excluded from the peritoneal
cavity | has formed a “ diaphragm,” similar in its relation to the lung,
though perhaps not otherwise homologous, to the “ diaphragm” of
Birds ; and that almost synchronously the fibrous tissue dorsad of
the lung (fig. 2*,*’) has obliterated the pleural cavity, thus
produced, as the pleural cavity 7s obliterated in Birds.

But of course, in the absence of an intermediate stage, one cannot
be absolutely certain of what happens ; and it is possible that the
changes which have taken place may be in part comparable to those
which lead to the formation of the “diaphragm” in Mammals. With
regard to the other divisions of the body-cavity, the left half of the liver
now lies in a closed sac (the /eft liver-sac) (fig. 2°, P./-liver-sac).
The closing of this sac has resulted, firstly from an extension back-
wards of that obliteration of the peritoneal space on the left of the
cesophagus which was seen taking place in the previous stage, and
secondly from the connection with the lateral body-wall of the fibrous

Proc. Zooxu. Soc.—1892, No. XXXIV. 34

494 MR. G. W. BUTLER ON THE [June 14,

posthepatic septum, which was also seen forming out of the ventral
ligament of the stomach.

The liver-sac of the right side (fig. 28, P') is still continuous, by a
long and very narrow peritoneal tubule (fig. 3%, P’), with the main
posterior peritoneal space.

Following this narrow tube backwards from the liver-sae, we find
that it runs externally to (on the right side of) the postcaval and
vitelline (or portal) veins, and that it contains a minute forward
continuation of the funnel of the oviduct, represented by a taised
groove on the wall of this small space. As this tube of communi-
cation is now so small, and has no apparent use, it is not surprising
that it should be obliterated in the adult.

In the figure (3) we see, cut through, a very small cavity, on the
right side of the stomach, in the corner between it and the lung.
This mtist be the remains of the ‘‘ omental space,” as to the persistence
of which in the adult of this species I am not certain (see list).

Lastly, as to the gastric space. This is also seen in section in
fig. 38 (P’). Following the sections backwards, we find that it is
still freely continuous with the posterior portion of the peritoneal
cavity.

Finally, at this stage, sections through the region of the pan+
creas show that the ventral ligamentous attachment of the alimen-
tary canal to the adjacent body-wall becomes here very broad ;
so that we can easily understand how, when the alimentary canal
comes to be bent and folded on itself, as it here does later on, the
gastric sac might become closed posteriorly, in somewhat the same
way as did the left liver-sac. The permanent kidneys (which in
the preceding stage were only just making their appearance, and
then had the peritoneum extending as a backwardly directed pocket
external to each and covering their mesial surface) are now fairly
developed, and it is found that the posterior part of each lies
completely outside the body-cavity. In the adult they come to lie
entirely outside it.

§ VIL. The Subdivisions of the Body-cavity in Snakes compared
with those in other Sauropsida.

[I here refer to the figures illustrating my previous paper (5). ]

(i.) The posterior peritoneal space seems to have its ‘exact
homologue in Crocodiles [(5) figs. 42, and 43, 3], and it is very
similar to the posthepatic cavity in the Lizard Tupinambis[(5) fig. 31,
3] or a Bird [(5) figs. 14-18, 3); but in the Bird there is on the left
side and in Z'’spinambis on both sides [(5) fig. 32, 0, o’] a connection
with the anterior part of the body-cavity. In fact :—

(ii.) Snakes agree with Birds (e.g. Gallus, Anas), Crocodiles, and
the Lizard Tupinambis in having a septum across the body-cavity
behind the liver (posthepatic septum). In Birds and Tupinambis
this septum is incomplete.

(iii.) The gastric space seems to have an almost exact homologue

1892.] BODY-CAVITY IN SNAKES. 495

in Crocodiles [e/. (5) figs. 42 and 43, in which a small unpaired
Space is seen in the region of the stomach *].

(iv.) The omental space is, as described above [§ IV. (iv.) note],
well represented in all the other groups of Sauropsida.

(v.) As to the fiver-sacs, the task of comparison is not so simple.
The ventral liver-sacs of Crocodiles are no more comparable with
those of Snakes than with those of Birds. We also soon see that
there is a considerable difference between the body-cavity in the
pulmohepatic region of Snakes and that in the corresponding region
of the Bird. Thus, if we start froin the median ventral ligament
of the liver and proceed outwards, we find in the case of the
Fowl [(5) fig. 45] that the spaces 1, | are bounded laterally by
the body-wall, or rather by the “ oblique septum”; but in Snakes
(fig. 3°) we pass all round the liver and reach the median dorsal
attachment of that organ. This difference is clearly correlated with
the fact that while in Snakes the “ pulmohepatic recesses ”’ are totally
or almost totally absent [see above, § VI. (i.)|, in Bitds they are
remarkably well developed [(5) fig. 45, 2, 2’).

In short, the “avian diaphragm” is developed out of fibrous
tissue on the ventro-mesial face of the lungs, which tissue bounds
these spaces (2, 2’) externally. But while the fibrous tissue, which
forms a sort of diaphragm ventral to the lung in Snakes, and
bounds the right liver-sac dorsally, appears to have a somewhat
similar relation to the lung, its other relations are different. In fact,
but for its adherence to the lung, one might, from its topographical
relations, rather compare the diaphragmatic tissue in Snakes with
that in Mammals.

It would seem hardly more possible to closely homologize the
“ diaphragm ” and liver-sacs of Snakes with those of Birds than the
diaphragm of Mammals with that of Birds. In the case of animals
which have descended from common ancestors along more or less
divergent lines, we ought not of course to expect to be always able
to compare directly correspouding parts, but rather to have to
content ourselves sometimes with tracing the condition of things in
each back to their common origin.

It may be remarked that the lungs of Varanus (Monitor) are
excluded from the peritoneal cavity by a sort of ‘‘ membranous
diaphragm”, and this is less markedly the case with the lungs of
certain Chelonia. It may well be, therefore, that the relations of the
lung in Snakes can be explained by a reference to one or both of
these groups; but this embryology alone can decide.

1 Tt is marked in these figures with a number 1, like the paired ventral liver-
sacs, because I was led to regard both the ventral part of the posthepatic septum
(8) which closes the liver-sacs posteriorly, and the fibrous tissue (8) which
closes this gastric sac posteriorly, as but lateral expansions of the median ventral
attachment of the stomach and liver, from which point of view the sac in the
region of the stomach and the paired ventral liver-sacs might be grouped
together. The embryology of Snakes seems to be in favour of the essential
similarity between the septa 3 (see § VI.) ; but as in Snakes this gastric space
is so distinctly posterior to the two liver-sacs, it may with advantage be
considered apart from them in both those animals and Crocodiles,

496 MR. G. W. BUTLER ON THE (June 14,

(vi.) Besides the definite subdivision of the body-cavity described
above, there are found in Snakes a number of modifications which
tend to obliterate the pleuroperitoneal cavity.

Consideration, however, shows us that these modifications of the
simple primitive condition (like those which lead to the definite sub-
division of the body-cavity) take place along lines which are followed
to a greater or less extent in other groups of Sauropsida. And
Snakes differ in this respect, to some extent, among themselves.

Thus, the obliteration of the pleural cavity may be compared
with what we find in Birds (and possibly also in Monitor Lizards, if
not in Chelonia).

Again, the complete exclusion of the kidneys from the body-
cavity, although the rule with the Snakes, is, we see, not. confined
to this order. A partial exclusion is rather usual [ante § IV. (i.)
and notes. |

Thirdly, the remarkable development of extra-peritoneal lymph-
cavities in Snakes, which still further reduces the space available
for the body-cavity proper—is but an exaggeration of what we
find in other Reptiles (e.g. Monitor and Amphisbenide) [ante
§ IV. (0)}.

Lastly, the relation of the alimentary canal to the peritoneum, so
often described, certainly does appear to be a peculiarity of Snakes ;
concerning this, Snakes differ among themselves, some departing less
than others from the common type (in which the intestine hangs by
a mesentery into the peritoneal cavity). The firm attachment of
the stomach in Crocodiles seems essentially similiar to that in Snakes.

§ VIII. Conclusions.

(1) In Snakes, as in Crocodiles, the pleuroperitoneal cavity is, for
great part of their embryonic period, very similar to that of adult
Lizards ; and the same is true of the earlier stages of Birds and
Mammals.

(2) In Snakes the simple, primitive, lacertilian condition becomes
during the later stages of development modified, in the following
ways :—

(a) The pleural part of the body-cavity becomes obliterated.
(6) The peritoneal part of the body-cavity becomes subdivided
into a definite number of closed spaces, viz. :
(i.) A posterior, or intestino-genital space.
(ii.) A gastric space on the left side.
(iii.) An “ omental ”’ space.
(iv.-) Two paired liver-sacs.

(3) ‘An examination of representatives of nearly all types of
Snake (see list) shows that however much they may differ, in actual
size, in the proportion of their parts, in various anatomical characters,
and in their habit of life, they all agree in the plan on which their
peritoneal cavity is subdivided.

(4) The subdivision of the body-cavity of Snakes proceeds in

1892. ] BODY-CAVITY IN SNAKES. 497

large measure along lines followed in effecting a similar subdivision
in other groups of Sauropsida. Thus :—

(i.) The omental space corresponds in all Sauropsida and it is a
closed space, as in Snakes, in at any rate certain Birds,
Crocodiles, and Chelonians.

(ii.) We may find in Sauropsida either a complete (Snakes,
Crocodiles) or partial (Birds and T'upinambis) posthepatic
septum across the body-cavity behind the liver.

(iii.) In Crocodiles, as well as in Snakes, we get the left, anterior,
portion of the posthepatic peritoneal cavity shut off as a
gastric space, leaving the remainder as a closed intestino-

: genital space.

As to each of the above-mentioned points, then, there seems to be
a fairly close homology between Snakes and one or more of the
other groups of Sauropsida.

(5) On the other hand, while there are points about the oblitera-
tion of the pleural cavity and the relations of the liver-sacs in Snakes
which remind us of what occurs in Birds, there is perhaps no closer
similarity in these respects between the two groups than between
the ‘‘ diaphragm” of Mammals and that of Birds,

2. On a Collection of Birds from the Island of Anguilla,
West Indies. By P. L. Sctater, M.A., Ph.D., F.R.S.,
Secretary to the Society.

[Received May 18, 1892.] ’

Mr. W. R. Elliott, one of the Collectors employed by the Com-
mittee of the Royal Society and British Association for the exploration
of the Lesser Antilles, paid a short visit to Anguilla * in March last,
and made a small collection of birds, which I have now the pleasure
of exhibiting. It contains 27 skins, which are referable to 16
species. There is nothing new or even rare amongst them, but as,
so far as I know, no ornithological collector has previously been in
Anguilla, and its Ornis is entirely unknown, it will be of interest
to record the names of the species represented in the Collection and
to add a few remarks.

Besides the species now mentioned Mr. Elliott writes that two
other birds were seen—a ‘ Chicken-hawk ” (perhaps Falco colum-
barius) and a Bittern (probably Butorides virescens). The former
was common, but the latter “‘ rather scarce at this time of year.”

Mr. Elliott was told that during the wet season a large number of
other birds visit the island. When he was there in March, every
thing was burned up by a three months’ drought. The birds obtained
are therefore ‘‘ undoubtedly permanent inhabitants.’”’ Amongst the
visitors during rainy season he hears of “ plovers, ducks, and snipes
in large flocks.”

In the following list I have given references to Mr. Cory’s most
useful ‘ Birds of the West Indies’ (Boston, 1889), in which all the
species are mentioned.

about 20 miles long and 6 broad, but is so low and flat that it cannot be seen
from a greater distance than 10 or 12 miles. The soil is calcareous and not,
very productive. A little sugar, cotton, tobacco, and maize are grown on it, but
it is deficient both in wood and water. In the centre of the island is a saline
lake which yields a large quantity of salt, the greater part of which is exported
to America, Theclimate is healthy. The chief occupations of the inhabitants
are breeding cattle and gathering salt.” —Jmp. Gazetteer, i. p. 158.

3. On the Insectivorous Genus Echinops, Martin, with Notes
on the Dentition of the allied Genera. By Oxprre.p

THOMAS.
[Received June 3, 1892. ]

At the Meeting of this Society on Feb. 13, 1838', Mr. W. Martin
exhibited and described an Insectivore belonging to the group known
as “ Madagascar hedgehogs,” but much smaller than the common
Ericulus setosus, and gave it the new generic and specific name of
Echinops telfairi, in honour of its donor, Mr. C. Telfair. A fuller
description, with accurate figures both of the animal and its skull,
was given by the same naturalist a little later’, and from these it
might have been easily seen that the animal was fully adult.
This specimen has remained unique almost up to the present time®,
and on this account, the species not being known, the name
Ericulus telfairi has been of late years wrongly assigned to Hriculus
Ssetosus.

The genus Echinops was properly reengnized by Wagner* (who

unnecessarily renamed it Echinogale), by Peters’, by Mivart”, and by
Grandidier*; but unfortunately Dr. Jentink, in an exhaustive and
otherwise most useful paper on the group, deceived by the small
size of the type, put it down’ as a young specimen of Hriculus setosus,
an example followed by Trouessart’ and Dobson®. The latter no
doubt overlooked the type now in the British Museum, and the two
former had not of course the opportunity of examining it.

Of this type specimen the cranium, figured by Mr. Martin, was
unfortunately lost before the Museum of the Zoological Society was
transferred to the British Museum, but the skin, the lower jaw, and
the bones of the trunk are still preserved. These confirm in every
way the accuracy of Mr. Martin’s description and figures.

The Museum has now received several specimens of this group
collected by Mr. J. T. Last at Manumbu, 8. Madagascar, which
clearly belong to two different species, a larger and a smaller, also
differing from one another by the number of their teeth.

The former of these is clearly Hriculus setosus, and the latter is
by its dentition an Hchinops, a genus which I now propose to
reinstate, but on the description of which by Martin and Mivart I shall
not try to improve, except with regard to the homologies of its
cheek-teeth, which will be referred to later. It may, however, be
noted that, apart from the general size, not always easily deter-
minable in these animals, the two forms may be readily distinguished
externally by the great difference in the size of the claws, those of
Friculus attaining a length in front of about 6 mm., and behind of
about 7 mm., while those of Hehinops scarcely exceed 3 in front
and 4 behind, with a proportionate reduction in thickness.

As to the species to which Mr. Last’s Hehinops belongs I am
more doubtful. Firstly, it appears to be smaller than Z. telfairi,
and to have smaller teeth, but the difference is very slight.
Secondly, the type of the older known species has the spines all quite
black-tipped and becoming gradually paler to the roots. On the other
hand, Mr. Last’s specimens, four in number, all have white-tipped
spines, the white extending over the terminal 2 or 24 mm. of the
spine?. In view of the great variability of Hriculus setosus in the
colour of the spines, this character must be looked upon with great
hesitation ; but at the same time the difference in appearance is so
very great that I think it should be recognized by name, and I
propose to call Mr. Last’s Echinops a new subspecies, giving it the
name of LF, ¢elfairi pallescens.

The following are the measurements of the typical skull of the
new form, the largest of five :—

Basal length 341; greatest breadth (between points of maxillary

7 M.Grandidier (/. ¢.) describes as “ E. mivarti” an animal which is “ noirAtre
et plus foneé que £. teffairi”; but the latter being superficially quite black, it ig
probable that he has mistaken the form to which the name F, telfairi belongs,
and that his mivaréi is really telfairi, and his ¢elfairi the one now described,

zygomatic processes) 16°7; interorbital breadth 9-1 ; palate, length
19-1, breadth outside p* 12°2, inside p* 4*7; length of lower jaw
from condyle (bone only) 27 ; height from coronoid to angle 13°4.

Of the five specimens examined, two others are of almost
precisely the same size as the type, and two, of similar age, are
rather smaller, the difference being, I presume, sexual. Unfortu-
nately the skins and skulls are not identified with each other, so
that I cannot say for certain whether in this form the male or the
female is the larger.

Now with regard to the homologies of the teeth of Echinops, the
five cheek-teeth of which have been supposed to be two premolars and
three molars, the reduction from the 3-3 of Hriculus being therefore
in the premolars,—I find on comparison that this is not the case, but
that the reduction is in the molars, of which there are only two,
while the premolars number three. These three premolars all have
milk predecessors, as is also the case in Centetes and Ericulus, and
therefore the missing premolar of the full set of four may be pre-
sumed to be p’, which is as yet not known to changein any member
of the Linnean group of Ferz. The incisors are two, above and
below, both in the permanent and milk series.

The full dental formula of Echinops is therefore

Comparing this with the formulz of some of the allied genera, we
find that Friculus is in all respects the same except that it has

M. i the totals therefore being 24. 36.

Two points about the milk-change of Hriculus may be specialiy
noticed, both of them showing a very low and unspecialized
eondition. The first is the extraordinary resemblance existing
between the milk-teeth and their respective successors, a resem-
blance so great that it is extremely difficult to say whether any
given set of teeth belongs to the milk or permanent series. And
this difficulty is increased by the second point, namely the fact that
the molars come up with and stand perfectly in series with the milk
premolars, the last molar being fully up and in use some time before
these commence to fall. This fact, in so lowly an animal, is
decidedly confirmatory of the recent suggestion that the molars even
of the Placentals really belong to the milk rather than to the
permanent series *.

1 This ingenious method of so writing the dental formulz as to show clearly
both the milk and permanent teeth and their relations to, one another is copied
from Dr. Winge’s paper “Om Pattedyrenes Tandskifte” (Vid. Medd. 1882,
p. 15). The method is so clear that no explanation is needed.

1892. | MR. O. THOMAS ON THE GENUS ECHINOPS. 503

Passing now to the dentition of Centetes*, besides the known
increase by one each in the number of the upper milk and the
lower milk and permanent incisors, we find a most remarkable and
noteworthy character in the number of the molars.

When writing his invaluable Monograph of the Insectivora,
Dr. Dobson stated* en passant, and merely as a question of specific
difference or identity, that certain specimens of Centetes ecaudatus in
the British Museum were much larger than usual, and had an
additional upper molar. Now remembering the continual and
unending discussion that the presence of four true molars in
Otocyon has given rise to, it is evident that the occurrence of a
fourth upper molar in Centetes is an exceedingly interesting fact,
and one that deserves to be brought into much greater prominence.

A renewed examination of the specimens shows that the presence
of four molars is not a merely accidental variation in one or two
individuals, but is a normal character of the species, although the
fourth molar only comes up very late in life—so late, in fact, that
the great majority of Museum specimens do not possess it. This is
proved by my finding the minute calcified germ of m* behind the m*
of what is, apart from the three unusually large individuals referred
to by Dobson, the largest skull in the Museum collection, and one
that, in the absence of these three, would have been put down as a
remarkably fine and well-grown one. Judging, therefore, by the
specimens in the Museum, it appears probable that the species seldom
attains to the great age necessary to obtain the fourth molar, but
that when it does, it normally has the additional tooth.

Curiously, however, not only is m*, like our own “ wisdom tooth,”
long behind m* in its date of appearance, but owing to the fact that
it projects further into the mouth and is rather feebly attached, it is
the first of the molars to disappear. For in one extremely aged
specimen, in which the molars and premolars are worn down to
the roots*, m* has again entirely disappeared, and has evidently been

worn down and dropped out in the natural course of existence.

1 Thanks to the kindness of Prof. A. Milne-Edwards, who has sent mea
complete copy of the chapter referring to the Tanrecs in Geoffroy’s rare
‘ Catalogue du Musée,’ I am most fortunately able to state that the name Setiger,
Geoffr. (1803), need not displace Centetes, Ill. (1811), a change which appeared
to be imperative on reading Trouessart’s paper, already quoted.

In this paper, while stating that Se¢iger was absolutely synonymous with
Centetes, the author exercised in favour of the latter that fancied right of
selection which has been so disastrous throughout the history of zoological
nomenclature. However, the copy now before me of Geoffroy’s words
shows that the typical and first mentioned species of his genus “ Setiger”
is “§. imauris,” whose characters are largely mixed up in the generic
diagnosis; and this animal, as we know from p: 22 of Isidore Geoffroy’s
paper on the group (Guérin, Mag. Zool. Mamm. (2) 1839, Art. 1), was neither
more nor less than a common Hedgehog which had lost its ears. This being
the case, Setiger becomes a synonym of Hrznaceus, Linn., and happily remains in
its time-honoured obscurity,

2 Mon. Insectiy. p. 69, pl. vii. fig. 7.

° This specimen presents an example of that mechanical wearing down,
and consequent increase in the number of ‘‘teeth,” on which Dr. Kiikenthal
in the case of a Seal has laid such stress (¢. c. p. 367) ; for its p* has formed two,
and its p® three minute “teeth,” these being of course merely the roots of
the proper teeth (see my own remarks, ¢. ¢. p. 311).

504 MR. O. THOMAS ON THE GENUS ECHINOPS. [June 14,

None of the specimens show any trace of a lower m*.

In these three genera of Centetide and, so far as I can make out
from the published figures, in Potamogale, we have a premolar
formula of 0 2 3 4; the p* (both milk and permanent) is abso-

a! 3

4
lutely molariform, while p* (again both milk and permanent) is
functionally a ‘carnassial”—characters all in contrast to those of
Solenodon, on whose close relationship to the Centetide so much
has been written.

In this animal there are, it is true, three premolars as in Centetes
and the others, but of these the first does not change, a fact which
seems to show that it is homologous with the non-changing p’ of
other Ferze, and not with the changing p’. If this be the case, and
the two posterior changing premolars be still looked upon as p* and
p', we get the formula P. {1 0 : = while as a further difference

p’ is absolutely premolariform, and it is p* that is functionally
“ carnassial’’ or semi-molariform, no premolar being truly molari-
form ; and finally there is neither that striking resemblance between
the milk and permanent teeth, nor the unusually early development
of the true molars, characteristic of the Centetide.

It appears to me therefore that not only was Dr. Dobson
perfectly justified in separating the Solenodontide as a distinct
family from the Centetide, with which Peters had placed them, but
I would go further and suggest that their main connecting link—
their common trituberculism—may be merely in each case a remnant
of a time when, as the American zoologists have shown, trituberculism
was afar more common character than at present, and that they
have really no very close relationship to each other whatever. The
proper solution of this problem will probably rest with the palee-
ontologists of North America, on which continent the ancestors of
Solenodon may be expected to have lived; and in consideration of
its great general and geographical interest, I would specially com-
mend it to the notice of any of them who may have the oppor-
tunity of examining remains referable to early Insectivora.

The following is a tabular arrangement of the formule above
described, with the addition of that of Gymnura, put in for com-
parison with the rest. Numbers in italics represent teeth which,
although present, are minute and apparently functionless. No
definite suggestions as to the serial homologies of p’ or of the molars
are intended to be conveyed by the type in which their respective
numbers are printed.

BovuLEeNnceER.
[Received June 7, 1892.]

(Plates XXIX. & XXX.)

Two small sets of Reptiles and Batrachians from Mt. Dulit *,
Sarawak, have been received from Mr. Hose and are now incorporated
in the British Museum collection. The first, received in August 1891,
contained examples of a single new species (Rana hosii, Bouleng.
Ann. & Mag. N. H. [6] viii. 1891, p.290). The second, received a
few days ago, is much more valuable, as it adds three new species to
the fauna of Borneo, among which is a remarkable form of Varanus.

I now proceed to give a complete list of the species represented
in Mr. Hose’s collection.

7. VARANUS HETEROPHOLIS, sp. n. (Plate XXIX.)

Teeth acute, compressed. Snout depressed, obtusely pointed,
as long as the distance between the anterior cornet of the eye and
the ear; canthus rostralis indistinct. Nostril an oblique slit, its
distance from the end of the snout thrice as great as from the orbit.
Digits rather elongate. Tail compressed, keeled above. Scales on
head rather large, flat, polygonal, subequal; ten across the snout,
from nostril to nostril, four across supraocular region and three
across interorbital region ; the middle supraocular series somewhat
enlarged transversely ; temporal scales very small. Nuchal scales
very large, round, flat, mostly with a short faint keel, widely sepa-
rated from each other by finely granular interspaces. Dorsal scales
feebly keeled, of very unequal sizes, those on the middle line smallest,
with two or three alternating series of very large oval ones on each
side ; a series of slightly enlarged scales on each side. Ventral scales
keeled, in about 80 transverse series. Caudal scales keeled, those
on the lower half twice as large as the others; caudal keel with a
very low doubly toothed crest. Dark brown above; a black
streak along each side of the anterior half of the nape, followed by
two crescentic black cross-bands on the nape and a thitd on the
back between the foré limbs: feddish brown beneath, throat
variegated with black.

Total length 1040 millim. ; tail 510.

A single specimen was received of this most remarkable new
species, which, though nearly allied to V. dumeriliz, differs from all
its congeners in the singular dorsal lepidosis, which somewhat recalls
that of another Bornean Reptile, Lanthanotus borneensis, described
some 15 years ago from a single specimen obtained at Sarawak, and
as to the systematic position of which we are still much in the dark
owing to the imperfection of Dr. Steindachner’s description. Some
time ago I pointed out the singular fact that the Frog and the Toad
with the longest legs known (Rana jerboa and Bufo jerboa) are both
from Borneo. A parallel case of superficial resemblance is now
offered by the similitude in scaling between Varanus heteropholis
and Lanthanotus borneensis.

subarticular tubercles feebly developed. Tibio-tarsal articulation
reaching the tip of the snout. Skin smooth, feebly granulate on the
belly ; a slight dermal fringe along forearm and tarsus; a dermal
flap above anus and at heel. Yellowish, with a few purplish dots on
head and back; a purplish line round the snout, from eye to eye,
passing through the nostrils.

From snout to vent 43 millim.

A single specimen.

8. CALOPHRYNUS PLEUROSTIGMA, Tsch.
9. CALLULA BALEATA, S. Mill.

10. NecTropHRYNE HosII,sp.n. (Plate XXX. fig. 2.)

Head broader than long ; snout short, obliquely truncate ; canthus
rostralis strong; loreal region nearly vertical, concave; interorbital space
broader than upper eyelid, slightly concave ; tympanum distinct,
vertieally oval, half the diameter of the eye. Fore limb long and

‘ strong; fingers webbed at the base, ending in rather large subtrian-

gular expansions, first much shorter than second ; toes short, with
small distal expansions, extensively webbed, but the three distal
phalanges of the fourth toe free; subarticular tubercles well de-
veloped ; two small, flat metatarsal tubercles ; a tarsal fold. Tarso-
metatarsal articulation reaching between eye and end of snout.
Above with small scattered warts, beneath finely granulate; a short
and narrow, but very prominent parotoid gland. Brown; throat
blackish. Male with an internal subgular vocal sac.
From snout to vent 60 milli:n.

A single male specimen. *

11. Buro quapriporcatus, Blgr.

12. Buro aspeR, Gravh.

Besides several small and perfectly typical examples, the collec-
tion contains a large female, measuring 215 millim. from snout to
vent, which agrees in every respect with B. asper except in the much
greater development of the parotoid glands, the length of which
equals their distance from the end of the snout and twice and a
half their width; they are disposed very obliquely, diverging behind.
I have felt tempted to describe this specimen as a distinct species ;
if I abstain from doing so it is because I can detect no other ground
for such a separation than the size and form of the parotoids, a
character which varies so much in certain other species of this
genus—B. marinus, B. regularis, and B. viridis, for mstance.

1892.] ON NEW SPECIES AND VARIETIES OF DIPLOMMATINA. 509

5. On new Species and Varieties of the Land-Molluscan
Genus Diplommatina from the Garo, Naga, and Munipur
Hill-ranges, Assam. By Lieut.-Col. H. H. Gopwin-
Austen, F.R.S., F.Z.S., &e.

[Received June 14, 1892.]

The arrival of a large collection of Land-Shells sent me by
Mr. T. H. Aldrich, of Cincinnati, U.S.A., and made by Mr. W.
Doherty in 1889 in different parts of the Naga Hills and Munipur,
has led me to take up and work out those belonging to the genus
Diplommatina ; for I had also in my own collection a number of un-
described species of the same genus which I had found when sur-
veying that country in 1872. I had also specimens collected by the
late Mr. Chennell in the Lhota Naga Hills and by Mr. Robert in
Munipur and the Garo Hills, making up a fine series for exami-
nation. Mr. Doherty made Kohimah in the Naga Hills his head-
quarters, and was there during the summer months ; he also collected
in the Eastern Naga Hills, south of Margarita, which is the terminus
of the Railway from Debrughur to the coal-workings and about
50 miles distant. In this neighbourhood he was, being in quite
unexplored ground, very successful as regards novelties, while at the
same time he extended the range of other species. Mr. Doherty
collected the minute specimens himself, while his men were looking
after Lepidoptera and Coleoptera; some of the larger shells were
brought to him by the Nagas, but he could not get them to search
for the small forms.

Although I was in the Naga Hills in the winter and spring only,
the driest time of the year, I got a fine series of the Land-Shells ; the
season does not make much difference on the high peaks, which are so
often covered with cloud for a part of the day, and the sun does not
penetrate into the damp northern ravines, I trained several men of
my party to collect, both Khasis and Ghoorkhas, and they became
most expert in finding the minute forms in the decaying vegetation,
and four annas for every new species or for a good number of specimens
was quite sufficient as an inducement to work hard. I found them very
keen of sight, and they very soon knew the different genera and those
I most wanted. Mr. Doherty was far too liberal in giving the Nagas
two rupees for shells. In the forests and noisome jungly ravines,
at times swarming with leeches, this work is not over pleasant, and
it is only the interest and excitement of finding some beautiful new
form at any moment that leads one on this lowly chase, as it has
me for many anhour. To the native collector it is far less exciting,
and he credits his master with making some wonderful curative out
of the animals.

In 1875 I published descriptions of three new species of this
genus in the J. A.S.B.; and under D. tumida, var., I then referred
to the great differences to be noticed in the shells from different
parts of the Burrail range, and urged that a careful examination
should be made of them all. I have now been able to better

this, aided by the additional material sent me by Mr. Aldrich, to
whom my very sincere thanks are due and also to Mr. Doherty who
collected them. This gentleman has extended the area of country
now collected in much farther to the east, up to Margarita, as I
mentioned before ; and these Naga Hills, inhabited by the most
Eastern representatives of this race, must not be confounded with
the Naga Hills inhabited by the Anghamis, which are 150 miles to
the westward. Thus one box containing a number of only partly
sorted tubes sent me by Mr. Aldrich had simply Naga Hills attached
toit. As Mr. Doherty’s letter, also enclosed, was dated from Kohima
in the Anghami Naga Hills, I naturally at first concluded they were
from that part. Fortunately, I afterwards found series of the same
species in tubes in another box, marked ‘‘ Margarita.’ It shows
how very carefully labelling should be done in the field.

Looking over a large series of the species of this genus, it is
of interest to note the much larger size of so many of the species
from the Naga Hill-ranges, as compared with those in the Khasi and
Garo Hills and the Himalayas. The change commences with
the rise of the Burrail Tertiary range, near Asalu. None of the
Khasi Hill species approach them in size.

D. scalaria, from the Garo side, is one of the largest, and that is
only 3°5 millim. in height of spire; while D. pachycheilus, 4°8, or say
5 millim., is the single large species from Darjiling. At Asalu we find
D. insignis 6°5 millim., D. tumida 5 millim., D. convoluta 6°25 millim.,
and, as will be seen in the new forms described in this paper, six are
5 millim. in height and over, two of them reaching 6 millim.

Of D. janitiaca, G.-A., one example was sent from Margarita.

Constriction in front, above the peristome ; sculptured throughout.

DIPLOMMATINA DECOROSA, 1. sp.

Loc. Anghami, Naga Hills (W. Doherty, in coll. T. H. Aldrich).

Shell elongately fusiform, not rimate; sculpture, fine, close, regular
costulation on all the whorls; colour pale whitish horny; spire,
sides somewhat flat, apex rather acuminate, rapidly diminishing ;
suture moderately impressed ; whorls 8, sides flatly convex, penulti-
mate and antepenultimate equal ; constriction above the aperture,
towards the outer margin ; aperture ovate, rounded below ; peristome
thickened ; columellar tooth small, in front.

Size: maj. diam. 2°5; alt. axis 5:5 millim.

There was one solitary specimen in my collection of this species
from uorth of the-Burrail, and 6 specimens, but smaller in size (4:5
millim. in height of spire), from the peak of Shiroifurar, in the
Lahupa Naga Hills, north of Munipur. Mr. Aldrich’s collection
contains a large number, and I have selected the type out of these.

On the boss of trap rock near the village of Phunggam I found
a number of a small variety, 4°5 millim. in height of spire, but
differing in no respect, except in size, from the typical species, only
that they are all of a pale sea-green tint.

The same form occurred on Kopamedza Peak, with this difference,

1892. ] SPECIES AND VARIETIES OF DIPLOMMATINA. 511

that the constriction was more to the right, directly over the outer
margin of the peristome. From Prowi, specimens were still smaller
in size, 3°8 millim.

Constriction in front, above the peristome ; last whorls smooth.

DieLoMMATINA GAROENSIS, Nl. Sp.

Loc. Garo Hills; exact locality unknown (W. Rodert).

Shell dextral, globosely fusiform, solid ; sculpture, distant, very
fine ribbing on the 3 apical whorls, the rest smooth and shiny ;
colour pale ochraceous ; spire high, side very convex; apex acumi-
nate, and when viewed from the side the axis is curved; suture
impressed ; whorls 63, all tumid, the antepenultimate much swollen
and by far the largest ; constriction above the aperture; aperture
vertical, oval; peristome very much thickened and double ; colu-
mellar tooth moderately large.

Size: maj. diam. 2°3 ; alt. axis 3°5 millim.

This species may be known by its very large antepenultimate
whorl and the curved axis of the spire, and its strongly developed
peristome and smooth lower whorls. It formed part of a collection
of shells made by Mr. W. Robert, of the Khasi Hills Survey party,
in the Garo Hills, during the military expedition into them in 1872—
73. Ten specimens were found.

DIPLOMMATINA ELONGATA, 0. Sp.

The typical shells of my D. tumida (J. A. S. B. xxxix. pt. 2,
p- 6, pl. ii. f. 2) came from Neuglo in the North Cachar Hills,
not far from Asalu. As I collected eastward the form changed, so
that in Munipur it does not correspond with the originaltype. Thus
on Nougmaiching Peak, 5135 ft., which is a conspicuous point seen
from Imphal, the capital of Munipur, and lying to the east of the
valley, a small form occurred, with the peristome less circular, the
form less tumid, and quite smooth on the last whorls.

On Laisen Peak, 5173 ft., in the mountains to the north of
Munipur, occurred another variety, which I describe below.

At Kezakenomih I found examples of a species which I described
and figured in 1875 (J. A. S. B. vol. xliv. pt. 2, pl. iv. fig. 7) as
D. tumida, var. This, however, seems so very distinct, now that we
have a much larger series to look over, that it must stand under
another specific title, and I have named it D. ELONGATA, nD. sp.:
this was the original description :—

** Shell elongately fusiform, thin, pale yellowish green ; sculpture
very faint above, quite smooth on the three last whorls; spire
attenuate, sides flat; suture moderate; whorls 83 to 9, the ante-
penultimate the largest ; constriction in front above the aperture ;
last whorl ascends slightly ; aperture oval, vertical ; peristome double,
thickened, slightly reflected; columellar tooth small and remote.
Alt. 0°22; diam. 0°13 inch.

512 LIEUT.-COL. H. H. GODWIN-AUSTEN ON NEW [June 14,

DIPLOMMATINA TUMIDA, var.

Loc. Laisen Peak and Trigonometrical Station, Munipur.

Shell dextral, elongately fusiform, not rimate; sculpture, fine costu-
lation on the 5 apical whorls, the last smooth ; colour pale greenish ;
spire with convex sides, apex acuminate; suture well impressed ;
whorls 74, penultimate and antepenultimate equal ; constriction above
the aperture, but towards the right-hand side; aperture oval, vertical ;
peristome thickened, double ; columellar margin straight and angu-
late below, the tooth in front, moderately large.

Size: maj. diam. 2°4; alt. axis 5:0. millim.

DIPLOMMATINA CHENNELLI, Nl. Sp.

Loc. Lhota Naga Hills (Chennell).

Shell dextral, of solid form; sculpture, very fine, rather distinct
ribbing, with scarcely any relief ; colour pale ochraceous and sienna-
brown; spire flat-sided, apex acuminate; suture rather shallow ;
whorls 83 to 9, sides flatly convex, constriction in front, the last
two whorls equal in size ; aperture oval, vertical ; peristome thickened,
strong; the columellar margin vertical and angulate below.

Size: (1st sp.) maj. diam. 2°9 ; alt. axis 5-9 millim.

Size: (2nd sp.) maj. diam. 2°9 ; alt. axis 5:0 millim.

This has close affinities to D. labiosa from the Khasi and Garo
Hills; but, although far larger (nearly double), the columellar tooth
is much smaller, the spire more attenuate, and the general shape
differs. I name it after the late Mr. A. Chennell, an Assistant in
the Indian Survey Department.

DIpLOMMATINA BUTLER], N. Sp.

Loe. Laisen Peak, Munipur (Godwin-Austen).

Shell dextral, tumidly fusiform ; sculpture, none on the last 3 whorls,
very distant, strong costulation on all above ; colour pale sienna-
brown, fresh shells glassy and polished ; spire conic, rapidly diminish-
ing, apex small; suture well impressed ; whorls 73, penultimate and
antepenultimate about equal, sides very convex, constriction above
the aperture; aperture nearly circular, vertical ; peristome double,
strong, continuous; columellar margin vertical, angulate below,
the tooth large, in front.

Size: maj. diam. 2:0; alt. axis 4:4 millim.

Six specimens were obtained, together with those of D. tumida, var.,
previously alluded to. This well-marked species was also found by
me at Prowi, in the Lahupa Naga Hills, at the head of the Lanier
River, which drains into the Kyengdwen of Burmah, and was
abundant there. I have also two specimens from Kezakenomih.

Two specimens from Klang Sing, Naga Hills, are rather more
tumid.

I name this after Capt. John Butler, who was the Political Agent
accompanying the Survey party on our exploring work, and who
unfortunately lost his life in an ambuscade laid by a hostile clan,
when the Survey work was again being prosecuted further east under

1892.] SPECIES AND VARIETIES OF DIPLOMMATINA. 513

Lt. Woodthorpe, R.E. Butler was a splendid officer for such a
frontier, and the Survey owed much to his untiring aid and to the
interest he took in its proper extension.

D1PLOMMATINA AMBIGUA, 0. Sp.

Loc. South of Burrail Range, Munipur (Godwin-Austen).

Shell dextral, large, solid; sculpture fine, rather close costulation on
all the whorls; colour horny white ; spire high, sides rather flat above,
apex rather acuminate; suture impressed ; whorls 8, flatly convex ;
constriction in front, above the aperture; aperture oval, vertical ;
peristome strong, closely double, reflected; columellar tooth small
for size of the shell, situated well in front and directed downwards.

Size: maj. diam. 3-0; alt. axis 5-5 millim.

This is one of the largest species from these mountains. I also
got it at Kezakenomih; one specimen measuring 6°5 millim. in
height of spire.

DIPLOMMATINA COMMUTATA, 0. sp.

Loc. Prowi, Lahupa Naga Hills (Godwin- Austen).

Shell dextral, elongately fusiform ; sculpture, 4 apical whorls finely
costulated, the last whorls nearly smooth ; colour pale sienna ; spire
with convex sides; suture moderately impressed ; whorls 73, sides
convex, antepenultimate rather the largest ; constriction in front,
above the aperture, but to the right side; aperture oval, vertical ;
peristome double ; columellar tooth sharp, well developed, directed
downwards and well in front.

Size: maj. diam. 1°75; alt. axis 3:0 millim.

A large form of this I found at Tellizo Peak, Anghami Naga
Hills, on the North Munipur frontier line.

Constriction on side, behind the peristome ; sculptured throughout.

DIPLOMMATINA DOHERTYYI, 0. Sp.

Loc. Margarita, Upper Assam (W. Doherty, in coll. T. H. Aldrich).

Shell dextral, very tumidly fusiform, strong, not rimate ; sculpture
fine rather distant costulation on all the whorls; colour very pale,
with a pinkish tint or ochraceous; spire, sides flat, rapidly dimin-
ishing, apex acuminate; suture impressed ; whorls 8, last 3 whorls
with convex sides, the penultimate the largest ; constriction on side,
well behind the aperture; the last whorl rises near peristome ;
aperture nearly circular, subvertical, rounded below ; peristome
double, outer somewhat reflected, and sinuous on margin ; columellar
tooth small, blunt, situated within the aperture, in many specimens
it is not seen when viewed directly in front.

Size: maj. diam. 3:0; alt. axis 674 millim.

This shell is from the Eastern Naga country ; there were two lots
in Mr. Doherty’s collection—one with a few specimens labelled
“ Margarita,” another, a numerous lot, marked only “ Naga.”

514 LIEUT.-COL. H. H. GODWIN-AUSTEN ON NEW [June 14,

DIPLOMMATINA THOMSONYT, 0. Sp.

Loc. South Burrail (Godwin-Austen).

Shell dextral, elongately fusiform; sculpture, 3 apical whorls
smooth, all the rest with very fine regular, rather close ribbing ;
colour whitish ; spire rather high, sides flattened ; apex rather blunt;
suture moderately impressed; whorls 74, sides convex, the ante-
penultimate the largest, last whorl ascending near the aperture ;
constriction lies directly behind and adjacent to the peristome ;
aperture oval; columellar tooth small for size of shell and lying
within the aperture ; peristome as usual.

Size: maj. diam. 2°4; alt. axis 5-0 millim.

I have named this species after Col. Mowbray Thomson, who, at
the time it was collected, accompanied our camp in his eapacity of
Political Agent of Munipur, while the boundary of that State was
being surveyed by me in 1872-73; in carrying out this work he
rendered us great assistance, although much thwarted by the un-
friendly action of the Munipur Durbar.

In general form this shell is like D. pachycheilus, Bs., a Darjiling
species, but the columellar tooth is never so large as in that species.

DIPLOMMATINA NENGLOENSIS, N. sp.

Loc. Nenglo, North Cachar Hills (Godwin- Austen).

Shell dextral, elongately fusiform, large, solid; sculpture very
fine, moderately distant ribbing ; colour pale ochraceous ; spire high,
with flat sides, apex acuminate; suture shallow; whorls 84, sides
flatly convex ; constriction some distance behind the aperture, on
side ; aperture widely ovate, expanded towards the outer margin ;
peristome double, not thickened; columellar margin subvertical,
the tooth very small and remotely situated.

Size: maj. diam. 2°9 ; alt. axis 5-0 millim.

This is a very distinct shell; in its very ovate aperture and small

columellar process or tooth it is unlike any other I have in my col-
lection.

DIPLOMMATINA DISTINCTA, 0. sp.

Loc. North of Burrail Range, Naga Hills (Godwin-Austen).

Shell dextral, small, rather depressedly fusiform ; sculpture very
fine close ribbing; colour pale horny ; spire conoid; apex blunt;
suture impressed ; whorls 7, sides convex, the antepenultimate the
largest ; constriction on the side, well behind the aperture ; aperture
vertical, irregularly ovate ; peristome thin; columellar tooth very
large for size and in front,

Size: maj. diam. 2-0; alt. axis 3-4 millim.

There is only one specimen of this species, but it is very different
from any of the smaller forms in having the constriction behind the

aperture, and, for so small a shell, in having the columellar tooth so
large.

1892. ] SPECIES AND VARIETIES OF DIPLOMMATINA. 515

Constriction on the side, behind the peristome ; last whorls smooth.

DIPLOMMATINA KHUNHOENSIS, Ni. Sp.

Loc. Khunho Peak and Trigonometrical Station, 8809 ft. above
the Mao villages, Naga Hills (in coll. H. H. G.-A.).

Shell dextral, ovately fusiform, not rimate ; sculpture, fine regular
costulation onthe3rd, 4th, and 5th whorls, the 2 apical smooth, the last
whorls polished and glassy ; colour pale sienna ; spire, side flattened
near the apex, which is somewhat acuminate ; suture impressed ;
whorls 8, the antepenultimate the largest ; constriction behind the
aperture ou the penultimate whorl; aperture oval and vertical ;
peristome double, strong, continuous; columellar tooth well developed,
rather remote.

Size: maj. diam. 2°2; alt. axis 4°8 to 5:2 millim.

Six specimens were found.

A form rather longer and less swollen occurs in the same range ;
about 30 specimens were obtained at Gnameh Peak (5585 feet), near
the Barak River.

There is another form much smaller, being only 3°5 in length,
with the same glassy last whorls and the constriction rather further
back, behind the aperture. Examples of this were also found at
Sikhamih, in the Lahupa Naga Hills. I distinguish this variety as
khunhooensis, var. minor.

DIPLOMMATINA LAPILLUS, Nn. Sp-

Loc. Kopamedza Peak, Lahupa Naga Hills, 8375 ft.(Godw.-Aust.).

Shell dextral, elongately fusiform, tumid below, not rimate;
sculpture fine, regular, close costulation, which is often much worn
down ; colour (bleached) ; spire with sides flattened, apex acuminate ;
suture shallow; whorls 8, sides flatly convex, the antepenultimate
the largest; constriction of the penultimate whorl on the side,
well behind the aperture; aperture oval, subvertical ; peristome
thickened, double, rounded below ; columellar tooth small and far
back within the aperture.

Size: maj. diam. 3:0; alt. axis 6-0 millim.

Three specimens, marked from the “north of the Burrail Range.”
Two are from the typical locality given above.

DIPLOMMATINA COMPACTA, Ni. Sp-

Loc. South of Barak in Munipur (Godwin-Austen).

Shell dextral, small, tumidly fusiform; sculpture, the two apical
whorls smooth, two next with fine close ribbing, the last three
whorls smooth or glassy ; colour pale ochraceous white ; spire, sides
rather flat, apex moderately blunt ; suture slightly impressed ;
_whorls 74, the antepenultimate the largest aud tumid ; constriction on
the side, well behind the aperture, at about 1 millim. distant ;
aperture oval, vertical ; peristome double; columellar tocth large
in front, and directed downwards.

Size: maj. diam. 1°8; alt. axis 3°5 millim.

516 LIEUT.-COL, H. H. GODWIN-AUSTEN ON NEW [June 14,

A larger shell, with rather a different shaped spire 4 millim. in
height, was found at Asalu, with the constriction in same position.

It is an allied form of D. jatingana, from the North Cachar Hills,
which is a larger, more tumid species with the constriction farther
behind the aperture.

A single specimen, only 3 millim. in height, was sorted out of the
box containing D. chennelli, from the Lhota Naga Hills.

Small species, with columellar process.

DIPLOMMATINA UNICRENATA, 0. Sp.

Loc. Eastern Naga Hills (W’. Doherty, in coll. T. H. Aldrich).

Shell dextral, ovately fusiform, subrimate, rather thin; sculpture,
distant strong costulation on ali the whorls; colour white, with a
pale lemon-yellow tint in fresh shells; spire with sides convex, apex
somewhat blunt; suture wellimpressed ; whorls 74, antepenultimate
the largest, sides convex, the constriction above the aperture, in front ;
aperture circular, vertical ; peristome double, outer wavy in outline,
with one very marked and decided crenulation on the upper outer
margin, and a slight sinuation on the left lower margin ; columellar
tooth large and directed downwards.

Size: alt. axis 4:0 millim.

A very large number of this new shell are in Mr. Doherty’s collec-
tion, four from Margarita in a tube, the remainder marked as from
the Naga Hills. This is a very beautiful new species, the only shell
approaching it that I know from this region being D. angulata of
Moulmain.

DIPLOMMATINA JAPVOENSIS, n. Sp.

Loc. Japyo Peak, Anghami Naga Hills, 10,000 ft. (Godwin-
Austen).

Shell dextral, fusiform, thin texture ; sculpture, close rather fine
ribbing ; colour pale ochraceous ; spire conic, apex blunt; suture
moderately impressed ; whorls 73, sides convex, swollen below ;
constriction in front, towards the outer margin of the peristome ;
aperture oval, vertical; columellar tooth fairly developed, blunt ;
peristome closely double, of weak structure.

Size: maj. diam. 2°4 ; alt. axis 3°8 millim.

This is larger than the other species from this peak and elevation;
and is the species described as D. sherfaiensis, var., J. A. 8. B. 1875,
p. 9, pl. iv. fig. 5; but as it is sufficiently distinct from the form found
on Sherfaisip Peak, far to the west, and also from another found on
Shiroifurar Peak, I think it better to give it a distinctive title.

DIPLOMMATINA ANIMULA, 2. Sp.

Loc. Prowi, Lahupa Naga Hills, Munipur (Godwin-Austen).

Shell dextral, ovately fusiform, thin and delicate, and glassy
texture; sculpture, rather distant well-marked costulation ; colour
whitish grey; spire moderately high, sides convex, apex blunt ;
suture impressed ; whorls 6, tumid, sides very convex, antepenultimate

1892. ] SPECIES AND VARIETIES OF DIPLOMMATINA. 517

the largest ; constriction in centre, above the aperture; aperture
widely ovate, vertical, angulate on the lower margin of the columella ;
the tooth large and well developed; peristome very strong.

Size: maj. diam. 1°3; alt. axis 2:0 millim.

This is another minute shell, differing from all others I have seen
in the strong peristome and large columellar tooth. JD. delicata is
its nearest ally.

DIPLOMMATINA SUBRUBELLA, Nl. Sp.

Loc. Japvyo Peak (Godwin-Austen).

Shell dextral, small, fusiform ; sculpture, fine, regular, rather close
costulation ; colour pale reddish; spire high, sides convex, apex
blunt ; suture impressed ; whorls 64, sides convex, penultimate and
antepenultimate equal ; constriction in front, above the peristome ;
aperture circular, nearly vertical ; columellar tooth very small and
internal ; peristome closely double, not thickened.

Size: maj. diam. 1°4; alt. axis 2°6 millim.

This is a close ally of D. sherfaiensis, but is much smaller and
has a coarser sculpture.

DIPLOMMATINA SUBTILIS, 0. sp.

Loc. Margarita (W. Doherty, in coll. T. H. Aldrich).

Shell dextral, elongately ovate, thickened ; sculpture, fine, close,
regular costulation throughout; colour pale sienna-brown; spire
with convex sides, apex blunt; suture impressed ; whorls 6, sides
convex, penultimate slightly the largest, the last does not rise
much upon the penultimate; constriction in front, but not well
marked ; aperture circular, suboblique ; columellar tooth well
developed for the size of the shell; peristome double, strong.

Size: maj. diam. 1:0; alt. axis 1°5 millim.

This is a good species, one of the smallest; its elongated form
separates it at once from D. parvula, the finer costulation and larger
size from D. minuta.

DIPLOMMATINA DELICATA, 0. Sp.

Loc. E. Naga Hills? (W. Doherty, in coll. T. H. Aldrich).

Shell dextral, very small, tumidly fusiform ; sculpture, very distant,
strong costulation ; colour pale horny ; spire rather depressed, sides
convex, apex blunt ; suture well impressed ; whorls 6, sides convex,
swollen, antepenultimate the largest ; constriction above the aperture ;
aperture ovate, vertical; columellar tooth well marked ; peristome
as usual.

Size: alt. axis 1°75 millim.

There are only two specimens in the collection among those merely
labelled Naga Hills, but I have every reason to think they were from
near Margarita.

518 LIEUT.-COL. H. H. GODWIN-AUSTEN ON NEW [June 14,

Small species, with very minute or no columellar process or tooth.

These should eventually be brought into a subgenus of their own.

DIPLOMMATINA MUNIPURENSIS, 0. Sp.

Loc. South of the Barak River, between the Mao villages and
Munipur (Godwin-Austen).

Shell dextral, elongately fusiform ; sculpture minute, close costu-
lation ; colour very pale greenish grey; spire symmetrical, sides
slightly convex ; suture well impressed; whorls 63, sides convex ;
constriction in front and immediately above the aperture; no colu-
mellar tooth, its position indicated by a slight sinuosity on the
columellar margin ; aperture nearly circular, subvertical ; peristome
closely double, very slight in form, the inner does not spread much
upward on the penultimate whorl.

Size: maj. diam. 1°5; alt. axis 2°7 millim.

From the number of specimens found, this appears a very abundant
species ; I never got anything like it in the Khasi Hills to the west.

DIPLOMMATINA VENUSTULA, 1. sp-

Loc. Japvo Peak, Anghami Naga Hills (Godwin-Austen).

Shell dextral, elongately fusiform, thin; sculpture, fine, regular,
close costulation throughout; colour pale amber ; spire high, sides
flattish, apex acuminate; suture impressed; whorls 73, sides
convex, the penultimate the largest ; constriction in front above the
aperture ; aperture widely ovate, suboblique; peristome but slightly
developed, varrowly double, expanded into a small wing on the
upper and outer margin, giving it a very sinuated margin; no
columellar tooth.

Size: maj. diam. 2°1 ; alt. axis 4-0 millim.

This species, of which I only obtained 3 specimens, is quite distinct,
as shown in the form of the spire and particularly the expanded side
of the peristome, which is an unusual character.

DIPLOMMATINA DOMUNCULA, 0. sp.

Loc. Margarita, Naga Hills (W. Doherty, in coll. T. H. Aldrich).

Shell dextral, fusiform ; sculpture, strong, regular, distant costu-
lation on all the whorls, much closer near the constriction, first two
whorls smooth ; colour pale whitish with an ochraceous tint ; spire
with convex sides, apex blunt; suture well impressed ; whorls 74,
sides convex, antepenultimate the largest, last whorl does not rise
upon the penultimate; constriction above the aperture ; aperture
circular, subvertical, curvilinear as seen from the side; peristome
double, not very much thickened; columellar tooth very minute,
internal.

Size: maj. diam. 1°3; alt. axis 3-0 millim.

This is a very distinct form, quite new to me, and belonging to a
group which is not represented, so far as I know, in the Khasi and
Jaintia Hills.

1892.] SPECIES AND VARIETIES OF DIPLOMMATINA. 519

DrpLOMMATINA SUCCINEA, 0. sp.

Loc. Anghami Naga Hills (Godwin-Austen).

Shell dextral, tumidly fusiform, thin and delicate in texture ;
sculpture, regular, rather close costulation ; colour very pale amber,
with stronger coloration on the apex; spire somewhat depressed,
suture impressed ; whorls 6, tumid, with convex sides; constriction
above the aperture ; aperture oval, vertical; columellar tooth only
indicated by a slight swelling; peristome double, strong.

Size: maj. diam. 13; alt. axis 2°0 millim.

This minute species may be compared with D. parvula from the
N. Khasi Hills, from which it differs in being larger, and in having
a greater number of whorls and a much more tumid shape.

DIPpLOMMATINA CONCINNA, 0. Sp.

Loe. Naga Hills, probably south of Margarita (Doherty, in coll.
T. H. Aldrich).

Shell dextral, solid, fusiform; sculpture, very strong, rather
distant costulation ; spire tapering rapidly, apex acuminate; suture
impressed ; whorls 7, sides convex, penultimate and antepenultimate
about equal in size; constriction hardly apparent, just above the
aperture; aperture circular, vertical; columellar tooth quite
minute, only an indication of it; peristome double, strongly deve-
loped.

Size: alt. axis 1°6 millim.

This is very distinct from any of the minute species I have hitherto
examined from this part of India; it is distinguished by its thick
shell and strong costulation.

Sinistral species.
D1PLOMMATINA GIBBEROSA, D. sp.

Loc. South of the Barak River between Munipur and Imphal
(Godwin- Austen).

Shell sinistral, ovately fusiform; sculpture, very distant fine
costulation, 9 ribs on the antepenultimate whorl when viewed from
the front ; colour very pale greenish ; spire low, sides rounded, apex
blunt ; suture very impressed ; whorls 43, very swollen, sides very
convex, penultimate much the largest; constriction on penultimate
in centre above the aperture ; aperture oval, subvertical ; peristome
double, strong ; columellar tooth small, internal.

Size: maj. diam. 1°5 ; alt. axis 2°2 millim.

The nearest ally of this species is D. jaintiaca, G.-A., figured in
the J. A.S.B. vol. xxxviii. pl. iii.; it differs, however, much in form,
particularly in the expanded penultimate whorl and in its very distant
sculpture. A very large number of it were collected in the above-
named locality, and a single example at Prowi in the Lahupa Naga
country.

In the collection sent me by Mr. Aldrich in a box marked Naga
Hills were about 40 specimens of this shell. The exact locality

was not recorded, but I take it they were from some part of the
Anghami Naga hills.

6. On the Brain and Muscular Anatomy of Aulacodus. By
Frank E. Bepparp, M.A., F.Z.S., Prosector to the

Society.
[Received May 3, 1892.]

The visceral anatomy of this Rodent has been described in the
‘ Proceedings’ of this Society’ by Mr. Garrod. The death of a
specimen recently deposited in the Menagerie enables me to
supplement that paper by a few notes upon the brain and the mus-
culature which were uot investigated by my predecessor.

I. Muscutar ANATOMY.

The Pectoralis major may be said to be composed of four more
or less distinct portions ; the attachments of these were at any rate
separate: the first part of the complex muscle is inserted on to the
deltoid ridge and is 16 mm. across at the insertion; immediately
below this is a slip of the extensive Panniculus carnosus. Above
this the second part of the pectoral is inserted on to the head of the
humerus and for a certain distance down the shaft; the insertion
is only slightly narrower than that of the first part, measuring
15 mm.; two smaller slips are inserted just below the second part

1 “On the Visceral Anatomy of the Ground-Rat (Auwlacodus swinderianus),”
P. Z.S. 1873, pp. 786-789.

1892.] MUSCULAR ANATOMY OF AULACODUS. 521

of the sterno-scapular; these may possibly be regarded as being
collectively the equivalent of the pectoralis minor of other animals.

Both Sterno-mastoid and Cleido-mastoid are present ; the latter is
of about half the size of the former and arises from the middle of
the clavicle.

The Omohyoid is present and is large.

The Levator clavicule is continuous with part of the panniculus
carnosus.

The Latissimus dorsi is a large muscle and gives off a good-sized
dorso-epitrochlear slip to the elbow; the latter is 8 mm. across;
the latissimus dorsi is inserted in common with the teres.

The Trapezius is extensive; it is continuous with part of the
panniculus, but its strong tendon can be seen to be separate.

The Rhomboideus is attached along the whole length of the
vertebral border of the scapula and also ventrally to the fascia
covering the supra-spinatus and to the spine of the scapula itself,
just at the point where the spine ends in the vertebral border of the
scapula.

The Sterno-scapular is in two parts: the shorter and narrower
part arises from the sternum and from the cartilage of the first rib ;
it is about 5 mm. across near to its origin; at the insertion it splits
into two parts—one entirely muscular, the other nearly entirely
tendinous ; the former joins the fourth part of the pectoralis, the
latter becomes continuous with the second and larger half of the
sterno-scapular.

The Deltoid is a double muscle: one part arises from the clavicle,
the other from the metacromion ; they are inserted together above and
to the outside of the insertion of the pectoralis to the deltoid ridge.

The Biceps is double-headed; the short head arises in common
with the coraco-brachialis.

The Coraco-brachialis is a single muscle; its insertion extends
7 mm. beyond the insertion of the ¢eres.

The Brachialis anticus has two heads of origin.

The Triceps is, as usual, a very massive muscle; the scapular
head is the largest, and arises also partly from the fascia covering
the infra-spinatus.

The Teres major ends in a flat tendon, 9 mm. across, which is, as
has already been mentioned, inserted in common with the latissimus
dorsi.

The Suéscapularis commences about 12 mm. away from the
vertebral border of the scapula.

The Pronator radii teres is inserted on to the middle of the shaft
of the radius; the half nearest to the insertion has a glistening
tendinous surface.

The Flexor carpi radialis arises from the flexor condyle of
the humerus ; its tendon begins 30 mm. from the origin.

The Flexor carpi ulnaris is a large muscle; the tendon, which is
broad and strap-shaped, is the widest of all the flexor tendons.

The Flexor sublimis arises from the flexor condyle and from the sep-
tum between itself and the flecor profundus ; it receives an excessively

522 MR. F. E. BEDDARD ON THE BRAIN AND [June 14,

delicate tendon (18 mm. long) from the ulnar head of the flexor
profundus ; it splits into three delicate nearly equi-sized tendons of
insertion ; of these the two outer are the thickest.

The Flexor profundus digitorum is composed of four parts: the
largest arises from the flexor condyle; this gives off a branch about
15 mm. from its origin, which ends in a thin tendon apparently in-
serted into the palmar cartilage; the main muscle passes into a
thick yellowish tendon which immediately joins that formed by the
other divisions: the second head of the muscle arises from the
middle of the shaft of the ulna; it becomes tendinous on the lower
surface just before joining the others; there is also another smaller
condylar head, which is soon joined by a head arising from the shaft
of the radius; these divide into four tendons.

The Extensores carpi radialis brevior and longior are precisely as
described by Messrs. Murie and Mivart in the Agouti; so, too, the
Extensor ossis metacarpi pollicis.

There were no traces that I could discover of the Hxtensor primi
or secundi internodii pollicis.

The Pronator quadratus is extensive, occupying nearly the whole
of the shaft of the arm-bones.

The Extensor carpi ulnaris arises from the extensor condyle by a
strong tendon on one surface and by a few fibres from the ulna; its
strong tendon of insertion, which is 15 mm. long, is rounded.

The Extensor indicis is a small muscle; it arises from the middle
of the ulna, and then becomes fused with the extensor mass.

The Extensor minimi digiti supplies digits IV. and V.

The Extensor communis digitorum divides early into three
muscular bellies: two of these pass into tendons, which supply
digits IV. and V. respectively ; the tendon of the third splits into
two, which go to digits II. and III.

The outside of the thigh is covered by a thick muscular mass,
composed of several elements which are not to be very easily dis-
tinguished ; a tendinous line separates the Biceps from the rest ; the
latter mass probably represents the Tensor vagine femoris, the
Gluteus maximus, and the Sartorius. It is largely tendinous at its
origin from the vertebral spines; the compound muscle is partly
inserted on to the fascia covering the knee-joint ; it is also inserted
by a strong tendon on to the lower margin of the femur, just in
front of the insertion of the Gluteus medius: I consider that this
part of the compound muscle is undoubtedly the Gluteus maximus.

The Biceps is an enormous fleshy mass; it has the usual double
origin and is inserted along the whole of the leg chiefly to the fascia
covering the leg, but also in front by a short tendon to the patella.

The Gracilis is a double muscle; the two parts run side by side,
arising from the symphysis pubis close together; they are also
inserted close together on to the fascia covering the leg.

The Semimembranosus is composed of two distinct parts: the first
part has a strong tendinous attachment to the inner condyle of the
femur; the second part is a long thin muscle from the caudal
vertebree and is inserted just between the two heads of the

1892.] MUSCULAR ANATOMY OF AULACODUS. 523

Gastrocnemius by a muscular insertion ; it recalls the femoro-caudal
of Birds.

The Semitendinosus arises by two heads; its flat strap-shaped
tendinous insertion on to the tibia commences just after that of the
gracilis.

The Gluteus medius is a powerful muscle hardly to be dis-
tinguished at its origin from the Gluteus minimus; it is inserted
along the lower margin of the femur in front of the great trochanter
for a distance of 30 mm.; the insertion is partly muscular and
partly tendinous ; the tendinous part of the insertion is divided up
into a number of more or less distinct tendinous insertions.

The Gluteus minimus is a powerful muscle difficult to distinguish
from the last at its origin; it arises from the greater part of the
ilium ; it becomes quite separate from the Gluteus medius a little
before the insertion on to the great trochanter.

There was no trace that I could discover of a Scansoriws, whose
presence is mentioned in several Rodents.

The Adductor magnus is not by any means a large muscle; it is
quite distinct from the other adductors; it is long and thinnish,
and arises from the symphysis pubis by a tendinous origin; the
upper surface of the muscle is glistening for a considerable distance
after the origin.

The other two Adductors form a large fleshy mass and are not
readily distinguishable from each other.

_ The Iliacus is a large muscle divided into two portions; it is
inserted together with the Psoas on to the lesser trochanter.

The Psoas magnus is a large muscle, also divisible into two parts ;
the part which arises most anteriorly becomes tendinous on one side
a couple of inches from its insertion.

The Pyriformis is present.

Both Odturators were present.

The Rectus femoris originates by two well-defined heads, which
are tendinous, though overlaid by muscular fibres; the muscle is
covered anteriorly by the Vastus externus.

The Gastrocnemius has the usual two heads, which take origin
from two sesamoids; the inner head is the smaller of the two.

The Plantaris arises in common with the outer head of the last,
and is fused with it for some way; it splits into three tendons on
the sole of the foot.

The Soleus is fleshy with a tendinous origin from the head of
the fibula; its exposed surface is glistening; it is inserted on to
the os calcis.

The tendons of the Flewvores tibialis and fibularis joi before the
latter splits into its four tendons of insertion: the tendon of the
Flexor tibialis seems to be mainly concerned with the supply of the
inner of the four tendons; the fourth of the four tendons of the
Flexor fibularis is very much smaller than the rest, which is of
course in relation to the comparatively rudimentary fifth toe; this
tendon arises from the lower surface of the conjoined tendons and
not from the outer edge.

524 MR. F. E. BEDDARD ON THE BRAIN AND [June 14,

The Tibialis posticus is covered by the Flexor tibialis; it
becomes tendinous halfway down the leg.

The Tibialis anticus appears to be quite normal in size and at-
tachments. So, too, the Hwtensor digitorum longus and the Extensor
hallucis (which is inserted on to the second digit, the first being
absent).

There are four Peroneal muscles; that supplying the fifth digit
is very slender, both muscle and tendon, and is inserted on to the
last phalanx.

The Peroneus quarti digiti is the outermost of the peroneal
muscles ; it is strong and has an insertion corresponding to the last
muscle upon the fourth digit.

The Peroneus brevis is inserted on to the outermost metatarsal.

The Peroneus longus is the most superficial of the peroneals in
origin; its tendon crosses the sole of the foot, as has often been
described in Rodents.

The musculature of this Rodent is clearly more like that of the
Hystricine genera than other forms; the arrangement of the long
flexor tendons of the foot conform to the type met with in the
Porcupines, Chinchillas, &c., and differs from the arrangement
characterizing the Sciuromorpha and Myomorpha’. As dulacodus is
usually associated with Capromys it might be expected that the
agreement in structure would be closer with that animal than with
the Porcupines: I mention Capromys particularly since it is one of the
few genera of the Octodontide of which the muscular anatomy
has been described ; its anatomy has lately formed the subject of an
article in these ‘Proceedings’ by Dr. G. E. Dobson*. There is, in fact,
a close similarity between the Rodent which forms the subject of
the present communication and Capromys; the principal differences
appear to be the following :-—

(1) The Deltoid in Capromys arises partly from the spine of the

scapula.

(2) The Latissimus dorsi has a double insertion, one part being

connected with the Pectoralis.

(3) There is no tendon(?) connecting the Flewor profundus

digitorum with the Flexor sublimis.

(4) The Gluteus medius is inserted by two thick tendons on to

the great trochanter.

(5) The Gluteus minimus is “a narrow long muscle”; its

insertion is between the two tendons of the last.

(6) The Obdturator internus is absent.

(7) The Semimembranosus has only one part.

In some of these points where Aulacodus differs from Capromys
it agrees with Hrethizon®: the Deltoid is like that of Hrethizon ;

so, too, is the Semi-membranosus in having two distinct parts ; there
is, however, too little known at present about the musculature of the
Rodentia to allow of any detailed comparisons of Aulacodus with
other types. I content myself therefore with pointing out the
above-mentioned differences from its near ally Capromys.

II. Viscerat ANATOMY.

As I have already mentioned, Prof. Garrod has described the
main points in the visceral anatomy of this Rodent ; I may, however,
call attention to a few matters which he did not specially dwell
upon.

The accompanying drawing (fig. 1) illustrates the ridges upon

Fig. 1.

Palate of Aulacodus, to illustrate the ridges upon the hard palate.

the hard palate ; these ridges, as will be seeu from the figure, are
symmetrical, and at the same time few in number; they are for
the most part in front of the molars. An inspection of the figure
will save the necessity for any further description.

The Spleen is of a triangular form; its longest diameter measures
27 inches, the shorter diameter 1? inches. The C@cum has been
very fully treated of by Garrod; but he was in error, as I have
already pointed out in a previous paper, in ascribing a unique
character to the structure of this part of the alimentary canal; in
Dolichotis there are a series of folds in the interior of the caecum
which bear not a little resemblance to those of Aulacodus. Garrod
has also said nothing about the folds of mesentery which support
the caecum ; near to the cecum the small intestine has a mesentery

Proc. Zoou. Soc.—1892, No. XXXVI. 36

526 MR. F. E. BEDDARD ON THE BRAIN AND __ [June 14,

on both sides; about half an inch away from the intestine a fold
arises from the mesentery supporting the intestine, which crosses
over the intestine itself and is attached to the cecum; a deep
pocket is thus formed which is of course floored by the ceecum; on
the opposite side there is a corresponding fold, arising, however,
rather further away from the intestine ; this also crosses the intes-
tine and becomes fused with the fold running directly from the
intestine to the cecum. The cecum is thus supported by three
distinct folds, of which the median one, that arising from the
intestine, is practically anangious ; the two lateral folds which arise
from the mesentery on the side furthest away from cecum bear
blood-vessels.

III. Brat.

The brain showed, after preservation in alcohol, the following
proportions :— :
Total length (to end of cerebellum) 37 mm.
Length of hemispheres 24 mm.
Greatest breadth 24 mm.
Vertical diameter 16 mm.

The outline of the brain as seen from above is shown in the
accompanying drawing (woodcut, fig. 2). The two hemispheres

are broader behind than in front; up to the Sylvian fissure the
outer borders of the two hemispheres are approximately parallel to
each other, though their outline is, of course, curved; from the
Sylvian fissure to the anterior extremity of the brain these margins
converge slightly, the diameter of the anterior extremity of the
brain being 11 mm. The form of the hemispheres is in fact more
like that of Octodon and Myopotamus among the immediate allies
of Aulacodus: there is less similarity in the general shape of the

1892.] MUSCULAR ANATOMY OF AULACODUS. 527

hemispheres to Capromys; this latter Rodent has the peculiar
rounded hemispheres that characterize the Porcupines. As in most
Rodents (and many of the lower Mammalia) the optic lobes are
largely exposed ; the degree to which the corpora quadrigemina are
exposed in Awlacodus differs from that of any Rodent with which
I have been able to compare its brain: the difference chiefly
depends upon the form of the posterior margin of the hemispheres ;
these are very closely approximated in the middle line, and diverge
posteriorly at a very wide angle; the posterior boundaries of the
hemispheres, indeed, meet almost in the same straight line ; there is no
widening out of the median sulcus to form a triangular space, such
as is evident, for example, in Dolichotis patagonica’ and all other
Rodents whose brains I have examined. As, however, the hemi-
spheres do not come into contact with the cerebellum in the middle
part above, there is a space left which is occupied by the two
posterior lobes of the corpora quadrigemina. These two only are
visible and they are raised almost to the level of the hemispheres
themselves. As arule, when the brain of a Rodent is viewed in
profile, the corpora quadrigemina are seen upon the floor of a deep
depression. Compare, for example, the accompanying drawing and
fig. 4 A of my paper upon Dolichotis quoted below.

The cerebral hemispheres of Aulacodus are but faintly fissured.

The Sylvian fissure is, however, well marked, though short in
extent ; it runs on each side almost vertically upwards, its direction
being, indeed, rather forwards at first and then curving backwards.
Just in front of the Sylvian fissure at its origin is a short backwardly-
directed furrow, which joins the Sylvian fissure, thus cutting off a
small triangular piece of brain about 2 mm. in length; this perhaps
represents the Island of Reil. The Sylvian fissure of Aulacodus is
much better marked than it is in either Myopotamus or Capromys,
in both of which the fissure is barely discernible.

The upper surface of the brain is but little marked by sulci;
I have already pointed out that there is not an obvious relation
between the size of the animal and the complexity of its brain-
convolutions in the Rodentia. The Beaver with its nearly smooth
brain is perhaps the most striking instance; and this example is
additionally remarkable from the fact that aquatic mammalia seem,
as a general rule, to have more richly convoluted brains than their
purely terrestrial relations. The only fissure is the longitudinal
fissure corresponding, I imagine, to that termed by Sir Richard Owen
“lambdoidal” ; the only fissures upon the brains of Myopotamus
and Capromys were the same, which is so strongly developed in
Dolichotis, Celogenys, and Dasyprocta. In Aulacodus this fissure
does not run, as it does in Dolichotis, continuously from one end of
the hemisphere to the other. There is a short fissure on each side,
7 mm. in length (a, in fig. 2); separated from this by a space
of about 5 mm. is the anterior part of it, which is even less
extensive. :

528 MR. B. B. WOODWARD ON THE GROWTH AND [June 14,

7. On the Mode of Growth and the Structure of the Shell m
Velates conoideus, Lamk., and other Neritide. By B. B.
Woopwarp, F.G.S., F.R.M.S. (Communicated by
Prof. FLowrr, C.B., President.)

(Received June 7, 1892.]
(Plates XXXI. & XXXII.)

At the June meeting of this Society in 1889 attention was drawn
by the writer to the very peculiar method of growth of the shell which
forms the principal subject of this communication, as was shown
by sections of specimens then exhibited. Unfortunately a far too
prevalent epidemic interfered for the time with further investigation,
which on being resumed has lead to more extended inquiry than at
first contemplated, with results, however, which it is hoped may
prove to be of some interest. The species was then spoken of as
Neritina schmideliana ; but on reference to the literature it appears
that this name cannot stand, since Chemnitz’s description’ was pub-
lished prior to the adoption, in the ‘Conchylien-Cabinet,’ of the
binomial system of nomenclature. The next name in order of priority
was that conferred by Gmelin in his edition of Linné’s ‘ Systema
Nature’ *, where he quotes Chemnitz, and under the impression it
was a sinistral species calls it Nerita perversa. This, however, is
such a complete misnomer that it seems wiser to set it aside, as
recommended in such cases by the British Association Rules, and to
adopt the specific name of conoideus conferred on it by Lamarck*. The
generic name of Velates proposed by Montfort” should also be adopted,
since, judging from the evidence afforded by its shell, the animal
must have differed in important respects from both of its nearest
allies—Nerita and Neritina. Other conchologists have described
and figured the shell, notably Deshayes, who also first figured the
operculum ; but all save Schmidel’ seem to have confined their
attention to its external aspect and to have overlooked its internal
arrangement and its remarkable mode of growth after the earlier
stages of its existence have passed. Before, however, this can be
dealt with it is necessary, in the first instance, to briefly describe
certain features in the internal structure of other members of the
family to which it belongs.

The Neritidee, it is well known, avail themselves largely of the
mollusean faculty of removing portions of the shell that may be in
the way of the animal in the course of its growth, and some of them
in this manner convert the interior of their tenement into a single
open chamber across which there projects from the side, immediately

behind the posterior portion of the columellar lip, a septum that
takes the place of the columella and serves as the point of attachment
for the posterior retractor muscle. This structural alteration is
effected not after the animal has completed growth, but proceeds
pari passu with it.

In Neritina a series of species may be selected which will exhibit
stages in the degree of removal of the columella and inner walls of
the whorls and in the development of the septum.

Neritina cornea, Linn. (Plate XXXI. fig. 1), VV. gagates, Lamk.
(fig. 2), and thin specimens of WN. zebra, Linn., and NV. dubia, Chem.,
show anearly stage. There is no true columella, and some portion of
the columella-edge of the spiral party-wall (or pavies) separating the
whorls has been removed. At the base of the columella-edge where
the parietal wall joins the projecting columellar lip the angle is filled
in with shelly matter strengthening the union between the two. A
slight spur of the shelly deposit runs in some cases (NV. gagates and
NV. zebra) up the columella-edge and supports it. The whole forms
a myophore and serves as a point of attachment for the posterior
retractor muscle, a slight salient point left in some species about
halfway up on the columella-edge of the whorl wall marking the
limit of its scar. In thick specimens of N. dubia (fig. 3), in N.
smithii, Gray, and in N. bicolor, Récl. (figs. 4 and 4 a), there is a
further thickening of the shelly deposit, which begins to spread over
the remaining portion of the parietal wall in the direction of the
apex. The columella-edge is additionally strengthened in J. virginea,
Lamk., and the paries nearly concealed by the increased deposition ;
whilst in WN. intermedia, Sow., and NV. punctulata, Lamk. (figs. 5 and
5 a), this shelly deposit completely covers the parietal wall, stretches
out from the columella-edge, and forms a veritable septum reaching
one third of the way across the whorl, its free margin becoming
thickened, pillar like, and firmly attached to the outer walls of the
shell by its spreading ends.

The next link in the series is supplied by that very peculiar species
N. latissima, Brod. (fig. 6), in which the septum with its pillar-like
margin stands away from the columella-edge, so that although united
posteriorly the septum and the remaining portion of the paries
project independently into the single chamber of the shell: the
septum is now the myophore. JN. fluviatilis, Linn. (fig. 7), and an
undetermined species (fig. 8) closely allied to N. canalis, exhibit a
further stage in which these two partitions stand slightly apart ; and
the distance between them is successively increased in N. canalis,
Sow. (fig. 9), WN. granosa, Sow. (fig. 10), and N. ¢ahitiensis, Lesson.
The parietal wall in adult specimens of the last-named disappears
entirely: it also is completely removed in N. crepidularia, Lamk.
(fig. 11). The Eocene form Tomostoma neritoides, Desh. (fig. 12),
undoubtedly comes very close to the last-named; not only does it
resemble it in its external characteristics, but also in the internal
arrangement of the septum and the lack of all trace of the parietal
wall.

One or two other points about the septum are worthy of note.

530 MR. B. B. WOODWARD ON THE GROWTH AND [June 14,

Where the free edge is thickened and pillar-like, as in N. inter-
media, N. punctulata, N. fluviatilis, and, to a lesser degree, in J.
latissima, the angle it makes with the septiform columellar lip
approaches the perpendicular ; where, however, the septum is widely
separated from the paries, as in WV. canalis and the species that
follow in the series quoted above, its free edge is thin, sharp, and
inclined more out of the perpendicular, the whole septum sloping
back from the aperture.

Towards the middle in WV. canalis the free edge of the septum has
a somewhat acuminate projection corresponding to that noted above
on the columella-edge in N. cornea, &c.

Viewed through the aperture of the shell only a very small portion |
of the septum can in these latter cases be seen; in its earlier stages
in the other species cited it is of course quite out of sight. The
shifting of the septum away from the parietal wall is due toa purely
mechanical cause. Just in proportion as the whorls of the shell
increase more rapidly and the spire at the same time becomes more
depressed, so the latter approximates the posterior angle of the
aperture, and consequently the inner wall of the last whorl becomes
smaller and smaller and less and less adapted to serve as a myophore.
Moreover, as the shell becomes flattened and the septiform columellar
lip extends further and further outwards from the axis, the angle at
which the retractor muscle would have to act in order to withdraw
the extended animal, were its fixed point still the remnant of the
paries, would be one of great disadvantage from a mechanical point
of view, and hence a fresh attachment, as near to and as much above
the aperture as possible, becomes of great importance and is obtained
by the forward movement of the septum already described. The
manner of this forward growth will be best dealt with later on when
the growth of the shell of Velates conoideus is under consideration.

In all cases, too, the scars of the anterior and posterior retractor
muscles are pronounced in proportion to the strength of the muscles
that were attached thereto, and, in consequence, to the thickness of
the shell and the septum. It must also be borne in mind that
the flattened columellar lip characteristic of Neritina and Nerita
is formed by the callus, as likewise is the “shelf” in Septaria
[= Navicella].

In Nerita the myophore at first sight appears as if it were a
remnant of the paries; but a closer inspection, if one may judge
from such typical forms as N. peloronta, Linn. (fig. 14), N. polita,
Linn., and NV. plewa, Chemn., reveals the fact that it is merely the
septum, all trace of the inner walls and columella having been
removed.

Velates, so far as at present kuown, is represented by but two
species—V’, conoideus, Lamk., and V. equinus, Bez., which occur
together in the Lower and Middle Eocene of the Paris Basin. The
Shell of the latter attains to close upon 4 whorls when full-grown,
and at that age corresponds in size with specimens of V. conoideus
that have only completed about 3 whorls. The internal construction
of the two at these respective periods is so similar that the description

1892.] STRUCTURE OF THE SHELL IN VELATES CONOIDEUS. 531

of one of them is sufficient, and no further reference need be made to
the growth of the shell in V. equinus since it is perfectly normal.
During the early stages of its growth, i. e. up to about 3 or 32
whorls, the myophore in the young Velates shell (fig. 16) is formed
of the remnant of the parietal wall strengthened by shelly deposit
much in the same way and degree as it is in Neritina virginea.
No trace of a prominence is perceptible at first on the thin and sharp
columella-edge, but by the time 34 whorls are finished it is plainly
discernible, and with the completion of the fourth whorl it attains its
maximum development (fig. 17d). The angle the columella-edge
makes with the columellar lip scarcely if at all exceeds 45° and is
less in the earlier stages, whilst the whole myophore rakes back from
the aperture and is not visible from without. After the completion
of the fourth whorl the growth of the septum is comparatively rapid
and increase takes place especially along that portion of its free
margin which is furthest from the callus. By the time 4} whorls
are complete the free margin is almost perpendicular to the callus
and has become thickened and pillar-like, a slight fold on it
marking the position of the late prominence (fig. 18d). The ap-
pearance of the septum at this stage is most like that of Neritina
punctulata amongst recent species. Shortly after the completion of
44 whorls (fig. 20d) the septum alone constitutes the myophore,
the columella and paries having been absorbed, and occupies the
relative position it retains throughout the remaining period of growth:
its free and thickened edge is quite perpendicular to the callus, and
the greater portion becomes visible through the aperture, although
the whole septum curves inwards as it projects into the chamber of
the shell. So far, therefore, as the myophore is concerned the shell
of Velates conoideus offers in the growth of the individual a series of
conditions which in the recent forms find their parallel in distinct
species :—in its earlier stages the paries and the incipient septum go
to form the myophore, as in the instances quoted; in the later
period the septum alone plays that part, as in Neritina crepidularia.

The scars of the retractor muscles, both anterior and posterior,
become more marked as the individual grows, the former especially
deepening with age, and there is a well-marked anterior palatal
apophysis which gradually becomes fainter as the shell grows and
finally almost entirely disappears. The callus which in the young
shell does not extend very far over the adjacent portion of the body-
whorl (fig. 15) gradually spreads further and further (figs. 16, 17),
till by the time 43 whorls have been completed (fig. 18) it has covered
nearly one half of the body-whorl and its line of demarcation is in
one plane with that of the margin of the outer lip. The rate of
increase of the third and following whorl is, moreover, proportion-
ately greater than that of the preceding ones.

It is at this point that the great change in the manner of growth
of the shell begins. First of all the callus is greatly thickened till
it becomes in proportion to the shell itself larger and thicker than at
any subsequent period (fig. 19). In the next place, further increase
of the shell begins to be effected by the addition of fresh material

532 MR. B. B. WOODWARD ON THE GROWTH AND [June /4,

not merely to the outer lip and columella alone as in normal growth,
but all the way round in the plane of the outer lip, as first evinced
by the deposition of periostracal layer along and over the outer
margin of the enlarged callus (fig. 20), the lines of deposition, or
growth, being continuous with those of the outer lip. In other
words, were it not for the overlap of the callus the peristome would
be complete, as in Neritina crepidularia and Tomostoma neritoides.
Deposition also takes place over the whole surface of the callus. The
direction of growth is in this manner completely changed. Instead
of developing spirally, round an axis of which the protoconch forms
the apex, the shell enlarges radially, the new axis being the pillar-
like margin of the septum and its apex the point, on the exterior of
the body-whorl, situated immediately over the junction of these two.
In this new condition of affairs the callus, which is at right angles
to the new axis, lies of course completely athwart the direction of
growth and decidedly in the way of further extension, so that the
animal must have found itself much in the same predicament that a
limpet would do were it to be suddenly half-decked when its period
of growth was still far from complete.

A grave problem in its domestic architecture was thus raised, and
the solution forms the most interesting feature in the life-history of
this species; for layer by layer, as deposition of fresh shelly matter
took place without, a corresponding amount of material was removed
on the inner side of the callus, and the additional room required
thus obtained. Put in homely phraseology, this mode of enlarging
a tenement reminds one of nothing so much as of the Irishman, who
raised his roof by digging out the floor of his cabin.

The ultimate outcome of this novel mode of increase is that, in the
adult Velates, that portion of the shell included between the margin
of the outer lip and a line (A B, fig. 21) joining its extremities and
passing round and a little below the apex on the further side is
normal, whereas the remainder is formed out of callus past and
present. This comes out very clearly in the various sections of the
shell presently to be described. Of course the walls around the apex
which require to be thickened as the shell increases in size, to make
them as durable as the rest, are strengthened in the usual way
by the deposition of fresh shelly matter within, so that, in an old
shell, what was once the cavity inhabited by the young animal has
become solid shell.

The changes which take place in the external form of the test of
Velates, as was to be expected, find their reflection in the intimate
structure of the shell itself. An axial section whose plane passes
close to and almost parallel with the edge of the columellar lip, but
just misses the apex itself, has been made in each of three young
shells of! different ages, and the sections stained with picro-carmine
to bring out the structure more clearly. In the first, a specimen
of about 3 whorls (Plate XXXII. fig. 22 a), the shell-wall near the
apex shows three readily distinguishable layers :—the outermost, or
periostracal layer, the crystalline, and the innermost layer, which in
shis case consists of the material laid down not merely as a lining to

1892.] sTRUCTURE OF THE SHELL IN VELATES CONOIDEUS. 533

the shell, but to fill up the space no longer occupied by the animal
and to thicken the shell where, having been formed when the animal
was young, it was too thin for the present requirement of its occupant.

The periostracal layer, which shows a tendency to divide into two
zones (fig. 226), is translucent and presents to the eye a fibrous
structure, the fibres being arranged at right angles to the surface in
the region of the apex; but as the layer is followed down towards
the anterior end of the columellar lip they change their direction
gradually till they assume the feather-like appearance familiar in
shell-structure and are arranged in a direction approximately
parallel with the layer itself (fig. 22 ¢).

The second principal layer also exhibits a fibrous appearance
consequent on the arrangement of its crystalline plates, which near
the apex are nearly but not quite at right angles to the surface.
As the columellar lip is approached these become more inclined, till
0% joining those of the columellar lip itself they unite with them and
sweep through an are of more than a quarter of a circle (fig. 24 ¢).

The layers of growth can in places be clearly seen (figs. 22 a, 6).
The innermost deposit is confined to the neighbourhood of the apex
and thins out as it recedes therefrom: it shows in section the cross-
hatched structure so common in sections of shell and due to the
especial arrangement of its component plates.

That the myophore at this stage is still formed in its upper part
of the parietal wall is evident from its structure and its continuity
with the outer wall next the apex (fig. 22a). The middle portion
of the myophore and the posterior wall have unfortunately been
broken away in grinding this section. Nevertheless sufficient of
the base of the former and of the callus out of which that base has
been formed is left to show that even at this early age a considerable
enlargement of the interior by absorption has taken place.

In the next older specimen, one of about three and a half whorls
(fig. 23 a), the remnant of the parietal wall can be traced, the section
being perfect, for quite two-thirds of the length of the myophore, whilst
in the outer wall on the posterior side of the section the remnant of
another original wall is present. A portion of the periostracal layer,
about halfway down that side, curves inwards, traverses the shell-
wall, and abruptly terminates on the inner side (p!./!.): it is overlain
by the edge of the callus which comes up to this point and which
is in its turn covered by a fresh deposit of periostracal layer that
joins on to the first one. This junction is not a true suture, since it
does not mark the union of two whorls. ‘The extent to which the
callus has been absorbed on its inner side is clearly shown, as also
the vertical arrangement of its component plates. This structure,
however, is still better seen in more advanced stages of growth.

The third section (fig. 24 a) has been taken of the young shell at
the stage when its four and a half whorls have been completed and
the period of radial growth entered on, just at the time when the
callus having attained its maximum development begins to be covered
all round its margin by the periostracal layer. The myophore is
still in part formed of an old outer wall of the test, but that portion

534 MR. B. B. WOODWARD ON THE GROWTH AND [June 14,

was callus (c’), as shown by the structure, and has been shaped to
suit its present position, as the transverse direction of its lines of
growth testify. The wall on the posterior side of the section is
built up of an old whorl, of callus, and of infilling material. The
absolute apex of each of these two last specimens appears in the
succeeding section of the respective shells,and here may be seen the
remains of the true spire, such as it is, and the overlapping sutures
(fig. 24 0).

These remnants exist in the adult shell, unless indeed it be a
worn specimen ; all other traces of former walls have disappeared.
A section taken through a full-grown specimen as nearly as possible
in the plane of the septum (fig. 25), and stained with picro-carmine,
clearly reveals the intimate relationship between the myophore and
the neighbouring walls of the test and demonstrates beyond doubt
the way in which they have been carved out of successive layers of
callus, for the lines of growth can be traced right across the septum
to its inner margin and reappear in the wall of the shell on the
opposite side of the cavity (see also fig. 26). They may also be
distinctly seen running round the walls on the interior surface of the
shell *.

The composition and intimate microscopical structure of the
Velates shell likewise call for some remark, since further points of
interest are presented by them.

The term pertostracal layer has been employed throughout,
instead of periostracum, for the external layer, the reason being that
it differs so widely in its composition from the chitinous substance
which coats most shells, and which usually is known by the latter
term, that its application in this instance might have been misleading.

This layer is remarkably hard and extremely difficult to cut
through ; it does not stain like the rest of the shell, but remains
translucent with a cloudy fibrous appearance when seen in the
microsections already described. It retains probably to a very high
degree (especially in the young shell) the coloration and mottled
markings which adorned the shell when living. Its line of junction
with the underlying crystalline layer in the young shell and that
portion of the adult where the growth is normal is even; but
where it overlies callus the several layers of the two inosculate and
the line of junction is extremely ragged and irregular (figs. 24 and
27). Inthe one case the mantle-edge that secreted it was advancing
over a given area followed in regular order by the portion that
furnished the material for the second layer ; in the other the mantle
was retreating from the area of deposition as the shell increased in
size and so gave rise to overlapping of the two series of deposits,
the irregularities that thus arose being further complicated by the
fluctuations in the growth of the animal and its shell.

Under the delusion that this periostracal layer might, like the
molluscan radula, prove to be very dense chitine, a portion was
placed in Mr. G. T. Prior’s hands for examination. He most
kindly made a careful investigation of it, with the result that it

1892.] sTRUCTURE OF THE SHELL IN VELATES CONOIDEUS. 535

appears in the main to consist of calcic carbonate, since it dissolves
with effervescence in dilute hydrochloric acid, leaving, however, an
appreciable residue. ‘This residue subjected to the usual tests, both
with acids and under the blowpipe, proved to consist of silica, having
a specific gravity which is nearer that of the crystalline than the
amorphous state. Naturally it was at first thought that this silica
might be a product of fossilization, but since the callus, which was
equally exposed to the same influence, yields no appreciable residue,
this does not appear to be a tenable supposition ; at the same time
without further and more extended inquiries one hardly likes to
look upon it as an original product of the animal’.

The crystalline layer which forms the principal thickness of the
shell-wall is composed of a single stratum of laminz, the component
fibres of which in each successive lamina run in a reverse direction
to those of the preceding one, as originally described by Count
Bournon* and subsequently by all writers on mollusean shell-
structure.

The direction these plates take, however, in the present example
is peculiar. In that part where the growth is normal (see fig. 21)
their direction coincides with that of the lines of growth, their planes
being perpendicular to the outer surface of the shell, just as seem-
ingly obtains in an ordinary Neritina (e. g. N. gagates). In the
remaining portion of the shell-wall beneath the periostracal layer
the plates follow the curve of the shell, their planes radiating from
the new apex and consequently being approximately parallel with the
outer surface—approximately, because the sections show that in each
major group of layers they ‘feather’ somewhat (figs. 25, 26, 27).

These walls being, as already mentioned, hewn out of successive
margins of former callus, it follows naturally that in the outer
margin of the callus itself the plates follow the same course—that is
to say, are disposed in a crescent, at the extremities of which, their
planes of inclination twisting to suit, they unite with those of the
outer lip to form a continuous circle. Along the dentate columellar
lip they also run parallel with the margin, and here, as elsewhere
over the callus, their planes are at right angles to the exterior surface.

On reaching the posterior angle of the aperture this series of
lamelle (viewed from the exterior) abruptly bifureates, one set
curving sharply towards the outer lip, the other in the opposite
direction, and both commingling with, and becoming lost in, the
marginal plates ; the point of junction of the two series thus forms
a centre whence they stream off in three directions (fig. 28).

At the anterior angle the whole series curves towards the outer
lip, becoming lost, as before, in the marginal set. Across the central
portion of the callus they run in an oblique direction, radiating from

a point situated a little way in from the posterior angle, their
course as they approach the margin becoming uniformly deflected
to the left, 7. e. in the direction of the anterior angle of the aperture.
The nature of this arrangement is, however, more easily gathered
from the figure than realized from a mere description. Seen from
the inner aspect the relationship of the internal septum to this
structure becomes apparent (fig. 29). The point by the posterior
angle of the aperture whence the plates radiate in three directions
marks the junction of the septum with the outer wall; the centre
of radiation a little further in falls just beside the septum in the
middle of its curved inner side, so that the direction of the plates in
the septum itself very nearly corresponds with the curvature of its
walls, or, to put it in another way, the ‘ graining’ of the septum is
but slightly ‘on the cross.’ The whole system of construction of
the callus, therefore, would appear to foreshadow the future
requirements of the animal, and its component plates to be so
arranged that when by erosion in the course of growth its unabsorbed
portions form part and parcel of the walls and septum of the shell
these plates shall be in the right position to impart the greatest
strength and durability to the whole that is possible under the
circumstances, for the lines of growth in the callus-formed
portion are of necessity lines of weakness.

Mr. H. A. Miers was so good as to investigate a portion of the
crystalline layer from the callus, testing its specific gravity by means
of density fluids. It floated in a liquid in which aragonite and
tourmaline sank; but foundered in one which would support beryl
and calcite. On account of its porous nature, the observed specific
gravity of the material must in reality be too low and the crystalline
callus is therefore more likely to be aragonite than calcite.

Mr. Miers further reports :—“ By taking some of the very finest
powder and examining it with a twelfth oil immersion, I am able
to find some specks which are undoubtedly calcite (by cleavage and
opt. char.). In section it is impossible to determine the substance—
because the use of the same objective with polarized light shows
that it consists of very minute overlapping fibres even where it
appears homogeneous under the quarter. Some of the powder
looks to me more like aragonite—little ragged fibres with straight
extinction, no cleavage, and the double refraction of aragonite.

“The final result is then—an extremely fine fibrous structure ; the
presence of calcite proved; the presence of aragonite highly pro-
bable.”

The manner in which the myophore and the callus shift forward
with the growth of the shell in Neritina can now be readily under-
stood. Fresh shelly matter is added to the outer and a corresponding
quantity removed from the inner side. No section can well be
taken to prove this to demonstration in the majority of the species
of the genus, but in N. crepidularia it can be shown that the callus
does thus change its position aud move through a segment of a
circle, keeping pace in this way with the growth of the rest of the
shell (fig. 30); and the same is true of Septaria [=Navicella]. In

1892.] STRUCTURE OF THE SHELL IN YELATES CONOIDEUS. 537

both, however, there is no change in the direction of growth, and
though the peristome is complete in the mature individual it does
not increase equally all round as in Velates conoideus, but develops
most rapidly at its peripheral point, the diametrically opposite edge
of the callus scarcely being added to at all and thus constituting the
axis on which the direction of growth pivots. A section taken in
the plane of the direction of growth displays the successive layers
of former callus spread out like a fan at this point (fig. 30).
Judging from external appearances there are but three forms which
at first sight would seem likely to exhibit the same structure and
mode of growth as Velates conoideus, viz.: Tomostoma neritoides,
Desh., from the Eocene, the Oolitic genus Pileolus, and Velatella
carditoides trom the American Cretaceous : all three are, so to speak,
like half-decked limpets in form and increase radially by the addition
of fresh material to the continuous peristome; but in neither the
first nor last-named, certainly, does the callus in any way overlap
the lateral walls of the test, nor is there any but the slightest change
in the direction of growth and that at a very early stage. A rough
section of the first, however (fig. 31), shows that whilst the callus
moves forward in the manner indicated above, the adjacent portion
of the wall of the test though continuous with it is probably normal
in its growth. Unfortunately the species is a small one and
material is scarce, whilst the shell is so fragile that the micro-
section which was being prepared crumbled in the final process, and
Mr. Riley, to whose skilful manipulation is due the successful series
of interesting sections on which this paper is'in part founded, was
too disheartened by the failure to essay any further attempts. With
regard to Pileolus it is much to be regretted that no definite opinion
can be formed, since the specimens are so completely mineralized
that all intimate structure is lost. Sowerby speaks of breaking
open one and discovering its internal spire’; but though Dr.
Woodward most kindly had two specimens cut, no such trace of
auy spire is visible in them, the only peculiarity being a thickening
of the columellar lip on its inner margin. It was impossible even
to make out if there is a septum or not, and it is necessary to
await the discovery of better preserved specimens before attempting
to pronounce further upon this genus *.

As for Vedatella, neither the original description * nor Tryon’s
figure * enables one to form any conjecture as to its probable mode
of growth.

* Since the foregoing paragraphs were written, Mr. W. H. Hudleston, F.R.S.,
the President of the Geological Society, has most obligingly lent me a section
of Pileolus which he possesses and which comes from the Lower Oolite, It
shows distinctly that in this genus there most clearly is a septum, as in Neritina
crepidularia and Tomostoma. The Museum sections must have passed just
through the spreading base of this septum at its inner margin where it joins the
callus. There is no true internal spire as stated by Sowerby. The shell in
this specimen was, as usual, far too altered to exhibit any trace of structure.

So far, therefore, as our present knowledge extends Velates
conoideus is absolutely unique in its method of building up its shell.

In conclusion it is the writer’s pleasing task to tender his
sincerest thanks to the many kind friends to whom he is indebted
for assistance and advice in the course of the preparation of this
paper. Beside those gentlemen already named he has to especially
thank Mr. G. F. Harris for the loan of specimens, and his friend
and colleague Mr. E. A. Smith for much assistance and advice.

1892.] THESECRETARY ON ADDITIONSTO THE MENAGERIE. 541

November 1, 1892.

Sir W. H. Flower, K.C.B., LL.D., F.R.S., President, in the Chair.

The Secretary read the following reports on the additions made
to the Society’s Menagerie during the months of June, July, August,
and September, 1892:—

The registered additions to the Society’s Menagerie during the
month of June were 132, of which 49 were acquired by presenta-
tion, 43 by purchase, 21 by birth, 9 were received in exchange, and
10 on deposit. The number of departures during the same “period
by death and removals was 90.

The registered additions to the Society’s Menagerie during the
month of July were 165; of these 92 were acquired by presentation,
27 by purchase, 2 by exchange, 34 by birth, and 10 were received
on deposit. The number of departures during the same period by
death and removals was 73.

The most noticeable acquisition during the month was a young
Gibbon from Hainan, South China, of a uniform black colour,
belonging to the species recently described (Ann. Nat. Hist. ser. 6, ix.
p- 145, 1892) by Mr. Oldfield Thomas as Hylobates hainanus.
The Society are indebted to Mr. Julius Neumann, of Hoihow,
Hainan, China, for this interesting animal, which is new to the
Collection.

The registered additions to the Society’s Menagerie during the
month of August were 151; of these 57 were acquired by presen-
tation, 34 by purchase, 5 by birth, 8 by exchange, and 47 were
received on deposit. The number of departures during the same
period by death and removals was 71.

The registered additions to the Society’s Menagerie during the
month of September were 99; of these 49 were acquired by presen-
tation, 27 by purchase, 12 were bred in the Gardens, and 11 were
received on deposit. The number of departures during the same
period by death and removals was 108.

The most noticeable addition during the month was a young male
Malayan Tapir (Tapirus indicus) from Tavoy, Burmah, presented by
Col. F. M. Jenkins. The general colour of this animal is that of
the adult, but the spots of immaturity are still visible on the legs.

Mr. E. Hartert exhibited examples of two new Mammals from
Dutch New Guinea (Proechidna nigro-aculeata and Acrobates pul-
chellus'), and a stuffed specimen of Apteryx maxima, belonging to

the Tring Museum.

542 PROF. NEWTON ON SYLVIA NISORIA. [Nov. 1,

The following letter, addressed to the Secretary by Lord Lilford,
F.Z.S., was read :—

“¢ Sir,

I think that it may interest some Members of the Society to
hear that a pair of Demidoff’s Galagos (Galago demidoffi), purchased
bv me from Mr. A. E. Jamrach on October 9, 1891, produced a young
one on April 28 ult., in a cage here. The infant was blind for several
days: its fur was very short and of a lighter colour than that of its
parents, which were both most careful and very jealous of their off-
spring. Iam glad to be able to add that we have succeeded in keep-
ing these three very interesting little animals alive and in excellent
health to the date of this writing on a diet composed principally of
cockroaches, mealworms, bread and milk, with occasionally a little fruit.

“ T remain,

“ Lilford Hall, Oundle, “Yours &e., :
October 19, 1892.” “ LILFORD.

Prof. F. Jeffrey Bell stated that Mr. Carruthers, Keeper of the
Botanical Department of the British Museum, had handed him a
fine specimen of Bipalium kewense, found in one of the warm houses
at Straffan House, Kildare. So far as Prof. Bell knew, this was the
first occasion on which this now widely-spread species had been
recorded from Ireland.

Prof. Newton, M.A., F.R.S., Vice-President, on exhibiting (on
bebalf of Mr. John Cordeaux) the skin of an immature Sylvia nisoria,
shot at Easington, near Spurn Point in Yorkshire, on the 19th ult.,
remarked as follows :—‘* When on the 4th March, 1879 (Proc. Zool.
Soe. 1879, p. 219), I had the privilege of calling the notice of the
Society to what I believed to be the remains of the first example of
Sylvia nisoria obtained in England, some of my friends thought me
rather rash in placing confidence in a specimen which had remained
unrecognized for about forty years, and had in the meanwhile changed
owners more than once. My conduct on that occasion has been in
some way justified by the recognition since that time of the occur-
rence of this species in various parts of the United Kingdom, and I
have now to lay before the Society an example which has been killed
in Yorkshire within the last fortnight, and sent to me by Mr.
Cordeaux for examination. The skin is that of a young bird of the
present year, and I may add that no doubt can be entertained of its
having been shot, as he informs me, at Easington, on the 19th
October, 1892, by Mr. Jalland.

**T have long wished to refer to this species the ‘ East Woodhay
Warbler, Sylvia bidehensis, described and figured by the late Hon.
and Rev. W. H. Herbert in the edition (published in 1833, anony-
mously, but commonly associated with his name) of White’s
‘ Natural History of Selborne’ (pp. 129, 130 note, and titlepage) ;
and despite some manifest discrepancies, due perhaps to his having
only seen and not procured the birds, I cannot but think that those

1$92.] sik E. NEWTON AND DR. H.GADOW ON THE Dopo. 543

which he observed, and possibly those seen by Mr. Sweet near
Bristol, may have belonged to Sylvia nisoria—a species with which
British ornithologists had at that time little or no acquaintance.”

Mr. F. Finn, F.Z.S., gave an account of his recent zoological
excursion to Zanzibar, and of the principal animals observed at
Lamu, Zanzibar, and Mombasa.

Prof. F. Jeffrey Bell, F.Z.S., read a description of a remarkable
new Kchinoderm of the genus Cidaris from Mauritius, taken from
a specimen recently transmitted to the British Museum by M. de
Robillard. Prof. Bell proposed to call this species Cidaris curvati-
spinis.

This paper will be published in the Society’s ‘ Transactions.’

A communication was read from Sir Edward Newton, K.C.M.G.,
C.M.Z.S., and Hans Gadow, Ph.D., M.A.,, F.R.S., F.Z.S., containing
an account of some of the bones of the Dodo and other extinct
birds of Mauritius, recently obtained by Mr. Theodore Sauzier, of
which the following is av abstract :—

In 1889 the Government of Mauritius appointed a Commission to
enquire into the ‘‘ Souvenirs Historiques” of that island; and in
furtherance of their object, at the instance of and under the able
direction of their President, Mr. Theodore Sauzier, they continued
the expleration of the Mare aux Songes—the marsh in which the
late Mr. George Clark, upwards of five-and-twenty years ago, made
the discovery of a vast deposit of bones of the Dodo’ and other
animals, mostly now extinct, and the only locality in Mauritius,
except Riche Mare, in the district of Flacq, where remains of the
Dodo have been found ?.

This exploration has been very successful, for not only have many
Dodos’ bones, some of them new and others represented only by
imperfect specimens, been recovered, but also a considerable number
of the bones of other birds, materially adding to our knowledge of
those that had been but partially described, and proving the former
existence in Mauritius of species either vaguely indicated by old
voyagers or wholly unsuspected to have been members of its fauna.
Beside these there have been found many remains of the large
extinct Lizard, Didosaurus mauritianus *, and several carapaces, plas-
trons, and skulls, more or less entire, though none absolutely perfect,
belonging to one or other of the extirpated Tortoises.

Nearly the whole of these specimens have been sent by Mr.
Sauzier, on behalf of the Commission over which he presided, to
the Museum at Cambridge, with a view to their determination and
to the description of such as are new, and this task has been under-
taken by the present writers.

Before preceeding to its execution, it may be as well to recall the

fact that up to the present time, beside bones of Didus ineptus,
those of the following birds have been obtained from this marsh and
described as under :—
Lophopsittacus mauritianus Lower Jaw. Owen, Ibis, 1866,

Fulica newtoni, A. Milne- Pelvis, Tibia, Metatarsus. Id. op. cit.

All these are species which no longer occur in the island.

Bones of a species of Phcenicopterus have also been found (G, Clark,
Ibis, 1866, p. 144, and A. Milne-Edwards, Ann. Se. Nat. sér. 5,
xix. art. 3).

Tie present collection contains not only bones of the above-named
birds, but also those of a Finch (?), an Owl, four other species of
Heron or Bittern, a Darter, a Gannet, a Goose, a Duck, a Grebe, two
species of Pigeon, one of which is probably the extinct Muningus
(Alectorenas) nitidissimus, a Waterhen, and two Petrels, of which we
proceed to describe and characterize as new :—

Strix (?) sauziert,

Astur alphonst,

Butorides mauritianus,

Plotus nanus,

Sarcidiornis mauritianus, and
Anas theodori.

In naming these species we wish by the first and last to com-
memorate the services to science of Mr. Sauzier; while the Aséur,
being in all probability identical with that recognized but left un-
named by Professor Milne-Edwards, may be appropriately dedicated
to him.

Of birds previously distinguished we have now for the first time
the following parts :—

Didus ineptus——Atlas, Prepelvic or ‘‘ intermediate” (18th) Ver-
tebra, complete Pubic Bones, and Metacarpals.

Lophopsittacus mauritianus.—Sternum, Femur, Metatarsus, be-
sides Lower Jaw far larger than that first described.

Aphanapteryx broecki.—Skull with Upper Jaw, third Cervical
Vertebra, Pelvis, Humerus, Femur’.

Fulica newtoni.—Cervical Vertebre (third and ninth or tenth),
Sternum, Sacrum, Humerus, Ulna, and Femur’.

1 There is a large series of tibixz (39 right and 50 left), which must belong to

one or the other of these two species, but except in a few cases it is impossible
to distinguish between them.

1892.] THE HON. W. ROTHSCHILD ON TWO NEW MAMMALS. 545

One specimen at least of each of the bones now first described
has been kindly presented by Mr. Sauzier, on behalf of the Com-
mission of which he is President, to the Museum of the University
of Cambridge, as well as a series of other bones in proportion to
the extent of the collection. ‘The remainder, including a magnificent
skeleton, which has been mounted in that Museum and is doubtless
the most complete in the world, of Didus ineptus, will be ultimately
deposited in the Museum of Mauritius at Port Louis.

This memoir will be published entire in the ‘ Transactions.’

The following papers were read :—

1. Descriptions of two new Mammals from New Guinea.
By the Hon. Watrer Roruscuixp, F.Z.8.

[Received November 1, 1892.]

In the face of the very exhaustive and explicit paper by Mr.
Oldfield Thomas in the Proceedings of the Zoological Society for
1885, I should not venture to lay before the Society a description
of a new Monotreme of the subfamily Echidnide, if I were not
backed up by such an eminent zoologist as Dr. Giinther. The latter
agrees with me that, as we have so little real knowledge of the habits
and distribution of the Monotremata, it is advisable to treat each
form as a distinct geographical race until such time as we have

a complete knowledge of all the forms and their exact geographical
distribution.

1. PROECHIDNA NIGRO-ACULEATA, Sp. NOv.

From having had the specimen here described alive I was able
to make a much more careful examination of it than if it had been
a dried skin.

It differs from Pr. bruijni in its much larger size, extremely
robust limbs, and much shorter claws. Another great point of
difference lies in the hair, for while Pr. druijni is covered with dense
woolly brown hair, in which are imbedded the few and scattered
spines, in the form before us the hair is long, bristly, and very
sparingly sprinkled over the body, the legs being almost bare. In
the new form the spines are almost as numerous as in Echidna
aculeata, but are of great length and thickness and of a horny black
colour ; while in Pr. druijni they are very few in number, short,
thin, and of a pure white colour.

In Pr. bruijni the claws are solid and much longer than in Pr,
nigro-aculeata, the middle claw of the fore foot being 17 inch long,
while that of Pr. nigro-aculeata measures only ? of an inch.

In addition to this, all the claws of Pr. nigro-aculeata are much
broader and considerably hollowed out on the under surface. Lastly,
Pr. nigro-aculeata has a much longer and stouter tail than Pr.
bruijni.

2. ACROBATES PULCHELLUS, Sp. nov.

I venture to think that this discovery of the late A. Bruijn’s will
prove of extreme interest to zoologists as adding a second species to
a genus hitherto represented by a single form, and also as proving
the much wider geographical distribution of a highly specialized

enus.
‘ This species differs from Acrobates pygmaeus of New South Wales
in its more purplish-brown colour, its broader and more robust head,
much shorter tail, and comparatively smaller body. On the ventral
surface it is much whiter than 4. pygmevs, and the whole of the
throat and sides of the lower jaw are pure white, while in 4. pygmaeus
they are yellowish grey. Round the eyes and reaching almost to the
nostrils is a blackish-brown patch. Ears rather smaller than in
A. pygmaeus. Tail in A. pulchellus 2} inches long, while in A.
pygmeus it is 34.
Hab. One of the small islands in Northern Dutch New Guinea.

2. On Mammals from Nyassaland.
By Ouprretp Tuomas, F.Z.S.

[Received August 20, 1892.]

By the kindness of Mr. Sclater I have been entrusted with the
examination of the fine series of Mammalia sent home to him by
Mr. H. H. Johnston, C.B., F.Z.8., Consul-General of Mozambique
and H.M. Commissioner for Nyassaland, under whose auspices they
were collected by Mr. Alexander Whyte, F.Z.S., a trained naturalist
and collector on Mr. Johnston’s staff, who is engaged in investi-
gating the fauna and flora of Nyassaland. It is impossible to speak
too highly of the scientific energy and public spirit of Mr. Johnston
in thus furthering our knowledge of the natural productions of the
region which he is called upon to govern—conduct very greatly in
contrast to that of many Englishmer in official positions, who, under
the name of sport, exterminate the native fauna of many most in-
teresting localities, without a thought either for the needs of science
at large or for those of their own National Museum in particular. Of
the specimens now sent home a full set is presented by Mr. Johnston
to the Museum, as is also the case with the birds, reptiles, and
animals of all classes, as well as with the plants which he has been
instrumental in getting collected for the benefit of science.

1892.] MR. 0. THOMAS ON MAMMALS FROM NYASSALAND. 547

Mr. Whyte, the actual collector, also deserves special mention
for the energy with which he has carried out the work entrusted to
him and for the care and attention which he has devoted to the
preservation of the specimens.

The region from which the present collection is derived is what
is called the “Shiré Highlands,” some of the specimens coming
from Zomba, where the British Consulate is, some 20 miles to the
west of Jake Shirwa, at an elevation of 2971 feet above the sea-
level; and others, in fact the majority, from the Milanji range
of mountains, about the same distance to the south of the lake,
and some 40 or 50 miles from Zomba. To this range Mr. Whyte
made a special exploring expedition in October and November
1891, and he has given a general account of the physical features
of the range, and its fauna and flora, in the Parliamentary report
quoted below’.

As might be expected from a collector of Mr. Whyte’s experience,
all the skins are carefully labelled with the exact locality, date, and
altitude, and the same was the case with the spirit-specimens; but
by an unfortunate accident, before these latter came into my hands,
the labels became separated from the bottles, so that the exact
details about them were lost. All, however, are either from Mt.
Zomba or Mt. Milanji.

The species are of course, as a whole, very similar to those obtained
by Prof. Peters in his famous exploration of Mozambique, and
described by him on his return to Berlin®. They are, however, by
no means of less value on this account, for the more our knowledge
of local variation extends, the more we need to have specimens
obtained at or near the localities explored by the earlier collectors.
Of actually new species there are none in the present instalment,
but there is little doubt that, as Mr. Whyte’s knowledge of
the locality increases, he will be able to obtain the rarer and
more local species, and among these there are certain to be some
novelties. One animal, however, in the present collection, the
Pallah, is so different from the ordinary specimens as to need a new
subspecific name, and the same may prove to be the case with some
of the other antelopes of the highlands of Nyassaland.

than is usually the case. This animal killed a donkey (full-grown)

exceptional case, and I do not think I ever heard before of a Leopard
killing its prey otherwise than by springing on the head and neck.

1 Ann, Mag. N. H. (3) xx, p. 827 (1867).

1892.] MR. 0. THOMAS ON MAMMALS FROM NYASSALAND. 549

Firstly, they prove conclusively that the latter species has a
seasonal change of colour, the two coats being the one a grizzled
rufous and the other a grizzled grey. Peters’s type, as figured by
him, was a changing specimen “with the anterior half of the body
grey and the postericr rufous. Specimen @ is in very much the
same state, and in my opinion unquestionably belongs to the same
species. From the relative lengtis of the two sorts of fur, it is
evidently changing from the rufous to the grey phase, and the
latter is therefore obviously the summer form. In specimen 3,
killed a month later, the change has gone a little further, the grey
fur having become as long as tle rufous, while the latter has much
decreased in area; the hairs on the centre of the back are deep
black to their roots.

Of the three co-types of S. shirensis, Gray, one, young, is in the
rufous state, except that its extremities ere grey, but the two adults
are both wholly in their grey coats. They are, however, quite
uniform in colour, and have no black patches on their backs. All
the specimens examined have one premolar only in the upper jaw,
although Peters’s type was said to have two, and on this account
S. mutabilis and S. shirensis were kept apart in Dr. Jentink’s
monographs of the African Squirrels *.

My own conclusion is that the new Nyassa specimens, with one
premolar, are certainly S. mutadilis, a determination which destroys
the importance of the presence or absence of the extra premolar in
this form, and then, this character being gone, that there is nothing
to separate the two forms but the black dorsal patches of mutabilis,
and that as to these we must be content to wait until further
specimens prove them to be due either to individual variation, to
advanced age, or to genuine specific distinction. But the fact that
the types of S. shirensis came, as their name implies, actually from
the River Shiré is strongly in favour of their specific identity with
Mr. Johnston’s Nyassa examples.

it is at present almost impossible to say whether G. afer, Gray,
G. montanus, Smith, G. leucogaster, Peters, G. boehmi, Noack, and
G. validus, Boc., are all or any of them worthy of specific distinction.
Much larger series from different localities will be needed before it
is possible accurately to work out this difficult group, and in the
meanwhile I use the earliest name available. In any case these
Nyassa specimens are so closely allied to the ordinary South African
Gerbille that little doubt can exist as to their specific identity
with it.

16. Isomys porsa.is, A. Sm.

. It appears on the whole more convenient to recognize Isomys as
a genus distinct from Jus, as it unquestionably is a natural group,
and no species really intermediate between the two are known.
Trouessart’s Lemniscomys I include, of course, with Isomys, as, apart
from the small value of striation as a generic character, certain of
the species (e. g. I. abyssinicus and I. variegatus) are quite inter-
mediate even in this character.

17. Isomys pumiLtio, Sparrm.

“The common Rat of the Milanji Plateau, 6000 feet; has a
metallic chirp very similar to the Warblers or Tailor-birds of Ceylon,
and I was sure at first that the noise came from a bird.” —A. Whyte.

These specimens, although rather smaller and more brightly
and definitely marked, may be fairly assigned to the typical Cape
I. pumilio; but the same cannot be said of some other specimens
hitherto referred to that form, which these beautiful specimens have
enabled me more carefully to examine and compare, and which I
now consider to represent two distinct subspecies, and may take this
opportunity of describing.

The first is a northern form, based on two specimens taken much
further north than the species was otherwise known to occur,
namely in Masailand, near Lake Naivasha. It may be called—

Isomys pumilio diminutus, subsp. n.

Size decidedly smaller, and tail shorter, than in typical Cape
examples. Ground-colour of body strongly suffused with yellowish
orange, especially on the rump. Inner surface of ear rich fulvons,
and a tuft of similarly-coloured hairs at the anterior base ; anterior
margin of outer surface shining black, as usual. Dorsal lines fairly
distinct, the lighter ones pale greyish white, the median and the
lateral of much the same tone. ‘Tail, as usual, blackish brown above,
yellowish white on the sides and below.

Dimensions of the typical skin.—Head and body 94 mm. ; tail 62 ;
hind foot 20°2.

Hab. Mianzini, just east of Lake Naivasha, Masailand.

Coll. F. J. Jackson. August, 1889.

The second subspecies is an inhabitant of Bechuanaland, Central
South Africa, and its colour peculiarities are those characteristic
of the desert representatives of striped forms in all parts of the
world :—

Isomys p. bechuane, subsp. n.

Size large; feet and tail much elongated; the latter nearly twice
as long as in J. p. diminutus. General colour sandy or fawn-grey,

552 MR.0O. THOMAS ON MAMMALS FROM NYASSALAND. [Nov. 1,

the dorsal stripes nearly obsolete, only just distinguishable. Ears
partaking of the general pallor, the anterior margin of their outer
surface pale rufous instead of shining black, and their inner surfaces
pale fawn. Upperside of tail scarcely darker than on the sides and
below.

While there cannot be the smallest doubt that these specimens
really belong to Peters’s species, it is an extraordinary fact that not
even the largest of them has more than four cheek-teeth in place,
the number characteristic of Georychus rather than of Myoscalops,
so that it is difficult to understand under what circumstances the
extra teeth are produced. Whether they are only formed in some
individuals and not in all, or, as is more probable, are only developed
in extreme old age, I am at present unable to decide. Specimens
abnormally larger than the general average should be sought for by
those having the opportunity, so that this most interesting point
may be settled.

The colour of the fur in the adult, or at least nearly adult, skin
6, confirms my doubtful identification’ of Emin Pasha’s Mandera
specimens with Peters’s species, for while the present animal is
unquestionably, from its locality, M. argenteo-cinereus, its colour
agrees precisely in tone with that of Emin’s specimens, and it is
equally different from that of Gray’s G. pallidus, the peculiar pale
colour of which still remains to be explained.

Little variation is presented by the different specimens except
in the case of the frontal white spot, which varies from 4
or 5 mm. in diameter to nil. |The young specimens are, as usval,

nearly wholly slaty grey, the buff tips to the hairs being a later
product.

The present is by far the most northern locality hitherto recorded
for this species, as, so far as I know, it has not previously been
described as occurring north of Natal. The specimen is unfortu-
nately young, and therefore the determination is to some extent
doubtful; but at the same time the rudiments of the dorsal spot, just
appearing, are black, and the teeth are decidedly of the hypsodont
nature characteristic of P. capensis and its allies. Adult specimens
of this Nyassa Hyrax would be of value in order to prove whether
there is or is not any geographical difference between it and its
Cape ally.

A local race of the common Pallah distinguished by its slenderer
skull and much shorter horns.

Height, judging from the length of the skull, probably nearly
equal to that of the typical Pallah, but the build, judging from the
form of the same part, probably much lighter and more slender.

Colours apparently precisely as in typical South African Z.
melampus ; no darker markings on face.

Horns conspicuously shorter than in the typical race, but other-
wise very similar to them in structure and curvature, and with about
the same number and arrangement of the rings. The amount of
the differences in size is brought out in the comparative table of
measurements (see p. 554); from it will be seen that the extreme
length of the horn in 4. m. johnstoni is barely more than once and
a half the basal length of the skull (157 to 100), while in_Z. m.
typicus the same dimension is considerably more than twice the
skull length (219 to 100).

Skull of about the same length as in the typical form, but
decidedly narrower (see table), especially in the frontal region, and
with the part just in front of the orbits more compressed at the
sides, so that the transverse diameter at this point is decidedly
less than on the muzzle above the molars, the two diameters being
approximately equal in the ordinary race. Palate narrow.

The skull and horns of specimen 4, rather younger, with the horn-
tips less worn, practically agree with the above-given measurements
in every way.

The discovery of this interesting animal is somewhat of a
surprise, for as the true Pallah is found over nearly the whole of
Africa south of the Equator, varying but very slightly in the size of
its horns, one would hardly expect to find so distinct a race in-
habiting Nyassaland, in the centre of the known range of the species.
However, the marked difference in the size of the horns, which
must result in a yery different general appearance, combined with
the great slenderness of the head, appear certainly to necessitate the
separation of the Nyassa Pallah as a distinct subspecies, if not as a
distinct species, from the true one, and this conclusion is fortified
by the entire agreement with each other of the two specimens sent.
That chosen as the type is rather aged, with worn teeth and horn-tips,
while the second, 4, although younger, has fully adult horns, as is
shown by the character of their basal rings.

I have connected with this beautiful Antelope the name of Consul-
General H. H. Johnston, the Governor of the district, and the donor
of the magnificent collection of Nyassa animals described in the
present series of papers.

3. Report on a Collection of Reptiles and Batrachians trans-
mitted by Mr. H. H. Johnston, C.B., from Nyassaland.
By Dr. A. Gtntuer, F.R.S., V.P.Z.S.

[Received November 1, 1892.]
(Plates XXXIII.-XXXV.)

Acting under instructions from Mr. H. H. Johnston, C.B., F.Z.S.,
Mr. Sclater has sent to the British Museum a series of specimens of
Reptiles and Batrachians collected by Mr. Alexander Whyte, F.Z.S.,
the naturalist attached to Mr. Johnston’s staff, in the Shiré High-
lands south of Lake Nyassa, principally upon Mount Zomba and
Mount Milanji.

Mr. Johnston has directed that the first set of these specimens,
after they are determined, shall be deposited in the National
Collection.

The present consignment consists of 90 specimens. These are re-
ferable to 12 species of Lizarps, viz.: Mubouia varia, Ptrs. ;
Mabouia quinqueteniata (Licht.) ; Sepsina tetradactyla (Ptrs.);
Agama atricollis (Smith) ; Agama mossambica (Ptrs.) ; Agama
hkirkit (Blgr.) ; Lygodactylus capensis (Smith); Lygodactylus an-
gularis (sp. n.); Chameleon dilepis (var. Ch. parvilobus, Blgr.) ;
Chameleon isabellinus (sp. n.); Rhampholeon platyceps (sp. n.) ;
Rhampholeon brachyurus (sp. n.).

Ten species of SNAKEs are represented, viz.: Typhlops obtusus
(Ptrs.) ; Uriechis capensis (Smith), probably = U. nigriceps (Ptrs.) ;
Psammophylax variabilis (sp. n.); Homalosoma lutrix (.); Ahe-
tulla irregularis (Leach) ; Leptodirarufescens (Gm.); Lycophidium
horstockii (Schleg.); Boodon lineatus (D. B.); Causus rostratus
(Gthr.); Clotho arietans (Merr.).

Five species of Barracutans are represented, viz. : Rana fasciata
(Tschudi) ; Rana nyasse (sp. n.); Bufo regularis (Reuss); Bre-
viceps mossambicus (Ptrs.) ; “Scolecomorphus kirkii (Blgr.).

The majority of these Reptiles and Batrachians, although pre-
viously known from other parts of Central and Eastern Africa, are
new to our knowledge of the Reptilian Fauna of the Nyassa district.
This knowledge is extremely scanty*, and embraces, even with the
aid of the present consignment, only a small fraction of the actual
number of species that must inhabit a district apparently so favour-
able to the development of Reptilian life. As we may shortly
expect further consignments, it would be premature to attempt a
comparison of this fauna with those of other parts of Tropical Africa,
and I proceed at once to the description of the new forms.

[Received September 3, 1892.] _

(Plates XXXVI—XXXVIII.)

The specimens forming the subject of the present communication
were brought from Russia by my friend Mr. A. Smith Woodward,
to whom they had been lent by Prof. H. Sjogren, of Upsala, for the
purpose of examination and description. They were obtained from
a Tertiary deposit, in company with a number of fish-remains, in
the Caucasus.

The bones are in a fine state of preservation, and before cleaning
were coated with a clayey matrix, among which were numerous
plates of selenite ; the nature of the matrix thus suggesting a deposit
very similar in character to our own London Clay. The specimens
comprise several fragments of jaws, numerous more or less imperfect
vertebree, and a single humerus; all evidently belonging to Ce-
taceans (assuming that the Zeuglodonts are rightly included in that
group). The vertebra and jaws indicate that we have to do with

three distinct forms, one of which was a Zeuglodont, the second a
more typical Cetacean of relatively small size, and the third a still
smaller dolphin-like Cetacean. The Zeuglodont remains indicate
a very small species.

In regard to the probable age of the deposit, it may be observed
that although Zeuglodonts occur in America in the Middle Eocene,
and in England in the lower part of the Upper Eocene (Barton beds),
in Malta they are found in the Miocene, where one of the forms is
of very small size. Moreover, since, with the exception of Zeuglodon
and Squalodon, together with the problematical Balenoptera (?)
juddi, Whales are unknown in the Eocene, while we have two
distinct forms in addition to the Zeuglodon from these deposits,
it might seem that the age of the latter is Miocene rather than
Eocene. So far as it goes, the evidence of the Zeuglodon might
be in favour of the same view, since such a small form as the one
before us might well be one of the last waning representatives of
its race.

With these preliminary remarks, I proceed to the consideration of
the specimens themselves.

I, ZEUGLODON CAUCASICUS, sp. nov.

The Zeuglodont remains comprise the hinder part of a left
mandibular ramus containing four teeth (Pl. XXXVI. fig. 1),
another fragment of a jaw with five broken teeth, a left humerus
(Pl. XXXVI. fig. 2), and an imperfect caudal vertebra (Pl. XXXVI.
fig. 3).

“The Zeuglodont nature of the figured jaw is shown by the teeth,
in which the serrations are as fully developed on the anterior as on
_the posterior border, thus differentiating the specimen from the
Squalodonts. The jaw is relatively deeper than in the so-called
Zeuglodon hydrarchus* of North America, but the chief peculiarity
of the specimen is its small size, which at once distinguishes it from
the American form.

The humerus (Pl. XXXVi. fig. 2) agrees in relative size with the
jaw, its total length being only 4°4 inches, whereas the corresponding
bone of Z. hydrarchus preserved in the Museum at Haarlem measures
8°6 inches *. In character both specimens agree very closely, although
the European example is distinguished by the greater development
of the deltoid crest (d), the more oblique form of the head (%), and
the less upward extension of the great tuberosity (¢); the upward
extension of this tuberosity in the Caucasian specimen is, however,
at least partly due to the effect of crush. Both bones are distin-
guished by the large size of the head, the compressed form of the

1 Dames and Gaudry regard this form as the female of the larger Z. cetoides,
but Cope (Amer. Nat. 1890, p. 602), who alludes to it as Z. brachyspondylus,
considers that it may belong to a distinct genus—Doryodon. That genus is
typically represented by the small Doryodon pygmeus, Leidy.

* There is a cast of this bone in the British Museum.

shaft, and the circumstance that the radius and ulna articulated to the
distal end by means of two slightly convex facets set obliquely to each
other, the one being anterior and the other posterior. It is quite evident
that there was but little, if any, movement between the humerus and
the radius and ulna, and that the whole limb formed a paddle strictly
comparable to that of modern Cetaceans, although probably somewhat
less specialized.

The peculiar structure of the humerus induces me to take this
opportunity of making a few observations as to the systematic
position of Zeuglodon. It will be remembered that in a recent
memoir Prof. D’Arcy Thompson’ has endeavoured to show that
these animals, in place of being Cetaceans, have ‘‘the closest
possible relation with the Pinnipedes.”’ In that memoir the author
has shown a wise discretion, from his point of view, in making no
reference to the humerus. If that bone be compared with the
humerus of a Seal it will be found that, beyond the fact that both
have a strongly-developed deltoid crest, there is not the most remote
resemblance between the two; the humerus of a Seal having
condyles like those of any ordinary mammal. On the other hand, I
submit, that between the Zeuglodont and Cetacean humerus there
is a very pronounced general resemblance ; both having a very large
head, directed outwardly in the natural position, a more or less
flattened shaft, and the distal end terminating in fore-and-aft facets
for the radius and ulna. It is true that in the Zeuglodonts the head
is relatively smaller, the shaft longer and more flattened, and the
distal facets more rounded than in modern Cetaceans; while the
latter have lost the distinct deltoid crest of the Zeuglodonts, and the
two tuberosities have become confluent. These differences appear,
however, to me to be precisely those which weshould expect to meet
with in a generalized form; and how it is possible to imagine that
an animal with a humerus of this type, and a true paddle, in place
of an ordinary fore limb, can have ‘‘the closest possible relation ”
with the Seals, passes my comprehension.

I do not propose to discuss all the points raised in Prof. Thompson’s
memoir, but it appears to me that several of the characters he
refers to as distinguishing the Zeuglodonts from typical Cetaceans
and allying them to the Seals are likewise merely generalized
features. For instance, the presence of a large spine and a small
coracoid process in the Zeuglodont scapula appear clearly to come
under this category, for I think few will deny that the enormous
coracoid of the ordinary Cetacean is an acquired and not an inherited
character, and the loss of the spine is assuredly so. Then, again,
the cervical vertebree, with their elongated centra, small lateral
canals, and approximated upper and lower transverse processes,
although undoubtedly very like those of a Seal, appear to me to be
merely another instance of the generalized characters of the
Zeuglodonts. In confirmation of this I may mention that Prof.
Cope * has recently figured the cervical vertebree of an undoubted

? Amer. Nat. 1890, p. 605, fig. 2.

1892.] AND OTHER CETACEAN REMAINS. 561

Cetacean (Priscodelphinus) from the American Miocene, in which
the vertebre have much longer centra than ordinary, with the
lateral canal small and nearly circular, and the roots of the transverse
processes approximated. Indeed, Prof. Cope speaks of the Cetacean
in question as having “a neck like that of a Seal in proportions.”

I am therefore of opinion that, instead of being nearly allied to
the Seals, Zeuglodon has much more the characters of a very
generalized Cetacean ; and that, if it should be found impossible to
ee it in the Cetacean order, it will have to form an order by
itself.

Reverting to the consideration of the specimens from the Caucasus,
I have to mention that I have merely figured the imperfect caudal
vertebra represented in Pl. XXXVI. fig. 3, which I believe to be
referable to Zeuglodon, in order to show its marked difference from
the caudal vertebra represented in Pl. XX XVII. fig. 2.

With regard to the question of species, I have first of all to mention
that the Caucasian Zeuglodont is certainly distinct from the larger
American forms, and likewise from the Egyptian ones described by
Prof. Dames *, which may be specifically identical with the former.
The Malta Zeuglodon has received no distinct name. Of other
named forms, 7. wanklyni, Seeley *, from the Barton beds, which is
founded on an unfigured skull now not forthcoming, is sufficiently
distinguished by its superior size—one of the teeth measuring 12
inch in length. 72. vasconum, Delfortrie *, from the Eocene of France,
is also a large species, founded upon the evidence of atooth. There
are also Z. paulsoni, Brandt*, from the Eocene of Russia, and Z.
puschii, Brandt *, from that of Poland; both these were founded
upon vertebrze, and appear to have been large-sized species. The
other European form is Z. vredense, Landois °, from the Hocene of
Westphalia, but this is not sufficiently characterized to admit of its
being at present regarded asa distinct species. Kokenodon onomata,
Hector °, from the Eocene of New Zealand, and Zeuglodon harwoodi,
Sawyer ’, from the Eocene of South Australia, are both large species
of Zeuglodon. The reference to Doryodon pygmeus, Leidy, from
the Eocene of South Carolina, which would appear from its name
to be a very small Zeuglodont, 1 have not been able to find.

Although I cannot be assured of the specific distinctness of the
present form from the last-named species, yet, as it is inconvenient
to allude to it without a separate name, I propose to call it pro-
visionally Z. caucasicus, its distinctive character being its small size.

II. UnpETERMINED CETACEAN.
(? Platanistide.)

The second species in the collection is represented by an associated
series of four cervical, and the first dorsal, a lumbar, and a caudal
vertebra; one of the cervicals being represented in Pl. XX XVII. figs.
1, 1a, anda caudal in figs. 2, 2aofthesame. The vertebree indicate
a Whale of the approximate size of the existing Beluga, with the last
four cervical vertebre free and of moderate length, and the lumbars
and caudals likewise of medium elongation. The form of both the
cervical and caudal vertebree shows that these specimens are not
referable to Zeuglodon caucasicus. The cervical vertebre are
represented by their centra, with the roots of the transverse pro-
cesses attached ; the figured example having a width of 3:1 inches,
a height of 2°2 inches, and an inferior length of 1 inch. The lumbar
has a length of 2°3 inches, and a width of 2°6 inches across the
anterior face of the centrum.

With regard to their affinity, it is clear, in the first place, that, as
they belong neither to Monodon or Delphinapterus, they cannot be
referred to any other existing genera of Delphinide, in all of which
the first two cervicals are united, and the remainder extremely short,
and generally more or fewer of them anchylosed. Free cervicals
occur in the existing Balenoptera, Megaptera, and Rhachianectes,
and the extinct Cetotherium. The small size of the specimens
renders it, however, somewhat improbable that they belong to the
Balenide ; and to this it may be added that they differ in certain
respects from those of Balenoptera. Moreover, we have no definite
evidence of the occurrence of Baleen Whales in the Lower Miocene,
to which it is quite probable that the Caucasian strata may belong.

The existing Platanistide and the numerous fossil forms referred
by Prof. Cope to that family all have free cervicals, and, from the
resemblance of the presentspecimens to some of the Miocene American
representatives of that group described by that writer, I am inclined
to think that they should be referred to the same family. The
resemblance appears to be closest with the series of vertebree figured '
as Ixacanthus, and I am by no means certain that the Caucasian
specimens do not indicate a member of the same genus, of rather
larger size than its typical representative. Still, however, I do not
propose to make any definite determination, leaving the matter with
the expression of my opinion that the specimens probably belong to
the Platanistide.

III. Intopsis cavcastca (n. g. et sp.).

The third Caucasian Cetacean is indicated typically by the hinder
portion of a cranium, and also by some fragments of jaws and several
vertebree probably referable to the same form. It is much in-
ferior in size to the preceding, and was of rather smaller dimensions
than the existing Inia: that is to say, its total length was some six
feet.

1 Cope, Amer, Nat. 1890, p. 603, fig. 1.

1892.] AND OTHER CETACEAN REMAINS. 563

The portion of the cranium is represented from the upper surface
in Pl. XXXVIII. fig. 2, and, although somewhat crushed, is in a fair
state of preservation. Alongside the Caucasian specimen there is re-
presented (fig. 1) the corresponding portion of the cranium of an ex-
tinct Cetacean fromthe Tertiary of Argentina, described by Burmeister *
under the name of Pontistes rectifrons (Bravard), which belongs to
the Platanistide. A comparison of the figures will show the close
relationship of the two forms at a glance. This is especially mani-
fested by the form of the maxillary fossz lying on the two sides of
the narial aperture. In both the fossils, as well as in the existing
Stenodelphis* and Inia, these fosse are characterized by their depth
and their squared posterior borders, which run close up to the
parieto-occipital surface. On the other hand, in the Delphinide
these fossee are shallower, and shelve upwards towards the occiput,
where they terminate gradually in a curved border.

The fragment of jaw represented in Pl. XX XVII. figs. 3, 3 ais one
of a pair, and is, I think, a portion of the rostral region of the left
maxilla. It contains 13 dental alveoli in the space of 5 inches, and
is of a long and slender form. The alveoli are laterally compressed.
These jaws have a great resemblance to those of the European
Miocene Schizodelphis suleatus*, in which the dental alveoli have
the same compressed form. If, however, as I think probable, they
belong to the form under consideration, it is quite evident that they
cannot be referred to Schizodelphis, that genus (although placed
among the Platanistide) having the maxillary fossz of the ordinary
Dolphin-like form.

The vertebrz do not call for any notice beyond the bare mention
that the centrum of a lumbar measures 1°3 inch in length and 1
inch in width.

Compared with Inia, the Caucasian cranium differs in the
absence of the high prominence behind the nares, in the smaller
development of the ridges bounding the maxillary fossee, and in the
less-inclined occiput. Assuming that the lower jaw belongs to the
same form, the teeth will also differ in their relatively smaller size
and lateral compression.

In many respects the fossil skull is more like Stenodelphis, but
the maxillary fossze are deeper, with more prominent borders; while
the recent form has not the large and well-defined square surface
behind the nares between these fossee. The teeth of Stenodelphis
are, moreover, cylindrical.

In Pontistes the occipital surface is more inclined forwards than
in the Caucasian fossil, and the space between the fossze behind the
nares is also narrower. The dental alveoli are, however, elliptical
in both. A much larger form has been described by Burmeister *
from the Argentine Tertiary under the name of Saurodelphis argen-

1 Ann. Mus. Buenos Ayres, vol. iii. p. 138, pl. ii. (1885).

Stenodelphis.

tinus, characterized by the great length of the rostrum and the
extreme compression of the dental alveoli. The occipital region is
more like that of the Caucasian fossil than is Pontistes, but there is
not the square flat surface behind the nostrils; while the dental
alveoli are quite different from those referred to the Caucasian form.

None of the other fossil forms referred to the Platanistide, of
which the skulls are known, have the maxillary fosse of the Inia
type; and I accordingly regard the Caucasian skull as indicating a
new genus and species, for which I suggest the name JIniopsis
caucasica.

The evidence that the Platanistide are a very ancient type has
been gradually accumulating; but the European Tertiary forms
hitherto referred to that group have more Dolphin-like skulls. The
occurrence of a form so closely allied to the South-American types
in Russia is therefore a matter of considerable interest. Its associ-
ation with the North-American Tertiary genus Zeuglodon is also
significant, and suggests that both these groups of Cetaceans had
originally a wide distribution.

P.S.—Since this paper was in type I have received from Dr. Sjégren
a copy of an article’in which the Cetacean-yielding strata of the
Caucasus are assigned to the Eocene.

Head elongate, finely rugose and pubescent, the vertex fulvous
with a central longitudinal groove, the supraorbital grooves rather
indistinct ; clypeus with a transverse row of punctures ; palpi fulvous;
antennz very short, extending only to the base of the thorax;
thorax subquadrate, rather broader than long, the anterior angles
distinctly tuberculate, the disc extremely closely and finely punctured,
the basal sulcus deep, the space behind it with a transverse ridge,
the anterior portion with a very short transverse groove at the sides,
the middle of the disc with two short elongate foveze, and another

Length 23-33 lines.

Head finely strigose-punctate, fulvous ; the eyes large, but slightly
indented ; the antennee two-thirds the length of the body, black, the
lower four joints fulvous, the third and fourth joints equal; thorax
proportionately long, strongly narrowed auteriorly, the sides nearly
straight, strongly deflexed, the surface entirely impunctate, the
posterior margin finely dentate, narrowly black, the median lobe
toothed, bisinuate; scutellum one half longer than broad, black,
shining, its apex broadly rounded; elytra not wider at the base
than the thorax, fulvous, with deep and regular rows of punctures,
of which the five inner ones do not extend to the base, the first
and second rows are very short and joined at the apex, the sixth
and seventh rows are also abbreviated at some distance before the
apex; a small black spot is placed on the shoulders, the extreme
basal and sutural margins are likewise of that colour; under-
side and pygidium black, clothed with long yellowish pubescence ;
the prosternum ends in a blunt projection in the male, but is
broadly truncate in the female.

Three specimens are contained in my collection.

CRYPTOCEPHALUS DOHRNI, n. sp. (Plate XXXIX. fig. 1.)

Black, thickly pubescent below, the thorax and legs fulvous, the
former finely punctate; elytra metallic green, strongly punctate-
striate, the interstices finely transversely rugose ; tarsi black.

Length 23 lines.

Rather broad and robust, the head closely punctured, greenish
black, the space between the eyes clothed with greyish pubescence ;
the antenne extending scarcely to half the length of the elytra,
black, the basal joint fulvous, the sixth and following joints slightly
widened ; thorax twice and a half broader than long, the sides
rather strongly deflexed, the lateral margin slightly rounded, the
surface opaque, fulvous, very minutely and closely punctured ;
scutellum black, not longer than broad, its apex truncate, the base
with a fovea; elytra parallel, pale green, distinctly punctate-striate,
the interstices very finely transversely rugose and sparingly clothed
with short silvery pubescence ; underside densely pubescent, black,
as also the tarsi, the legs fulvous, the last abdominal segment with
a deep round fovea; prosternum broad, flat, densely clothed with
greyish pubescence.

The elytra in this species, of which I received a single specimen,
are but slightly metallic and have a silky appearance on account of
the fine pubescence and rugose or finely wrinkled interstices.

EULYCHIUS NIGRITARSIS, N. sp.

Fulvous, the terminal joints of the antennz and the tarsi black ;
thorax rather sparingly punctured ; elytra strongly punctate-striate ;
femora dentate.

Length 2 lines.

Head finely and sparingly punctured, the vertex convex ; clypeus
finely rugosely punctate, separated from the face by a transverse
groove, eyes surrounded by a very narrow sulcus; antenne extending
a little beyond the base of the elytra, fulvous, the apical five joints
black, strongly dilated and transverse, the third, fourth, and fifth joints
equal, the sixth shorter; thorax transverse, the sides rounded, the
anterior angles rather acutely produced, the surface finely and not
very closely punctured on the disc; elytra not depressed below the
base, distinctly punctate-striate, the punctures much finer towards
the apex; femora with a small tooth ; the extreme apex of the tibie
and the tarsi black.

This species, like EZ. dorsalis, Duv., differs from the type in having
armed femora; the transverse apical joints of the antennz are,
however, typical. The black tarsi and general system of coloration
separate the present insect from the other two known species.

PHELOTICUS BRUNNEUS, n. sp. (Plate XXXIX. fig. 2.

Broadly ovate, robust, dark fulvous; the antenne (basal joints
excepted), the knees, and the apex of the tibiee black; thorax
subconical, very sparingly and finely punctured; elytra finely
punctate-striate anteriorly only ; femora minutely toothed.

Length 33 lines.

Head impunctate, the eyes with a very narrow sulcus at their
_ Inner margin, rather deeply notched, the epistome not separated
from the face ; jaws black ; antennz slender, filiform, extending to
nearly two-thirds the length of the elytra, black, the lower four
joints fulvous, the third and fourth joints equal; thorax subconical,
narrowed in front, the sides nearly straight; the disc about one
half broader than long, with a few fine punctures at the sides;
scutellum smooth, subpentagonal ; elytra much broader at the base
than the thorax, convex, with a very shallow basal depression ; the
shoulders prominent, bounded within by a longitudinal depression ;
the dise with a few rows of fine punctures distinct only anteriorly,
nearly obliterated below the middle; underside and legs fulvous,
the apex of the femora and of the tibize as well as the claw-joint
black ; femora with a small tooth; tibize not channelled, the four
posterior ones deeply emarginate before the apex; claws appen-
diculate, the inner division very short and pointed; prosternum
slightly longer than broad, concave, deeply punctured, the thoracic
episternum strongly convex.

A rather aberrant species and not typical of Pheloticus or allied
genera, apparently allied to P. ser¢punctatus, Fairm., but differing
in the colour of the antenne and legs.

Puetoricus (?) ZNEICOLLIS, n. sp. (Plate XXXIX. fig. 4.)

Below obscure seneous, the abdomen fulvous, the head and
thorax greenish zeneous, nearly impunctate, antennz fulvous; elytra
flavous, strongly punctate-striate, the sutural and lateral margin
and a discoidal longitudinal stripe, not extending to the apex,
greenish zeneous.

Length 13 line.

Head finely and distantly punctured, metallic eeneous; eyes rather
broadly emarginate, surrounded by a very narrow sulcus which
extends downwards to the epistome, which is separated from the
face by another transverse groove; clypeus broadly subquadrate,
impunctate, labrum fulvous ; antenne filiform, extending to about
half the length of the elytra, pale fulvous, the apex of the terminal
joint black, the third joint distinctly shorter than the fourth, the
terminal joints slightly thicker ; thorax twice as broad as long, the
sides rounded, narrowed towards the apex, narrowly margined,
the anterior portion rather strongly deflexed, the surface very
sparingly punctured, metallic greenish eeneous; scutellum tri-
angular, fulvous, its apex zneous; elytra subcylindrical, slightly
broader at the base than the thorax, with a shallow depression below
the base, fulvous, strongly punctate-striate, the punctures nearly
disappearing at the apex, the sutural margin narrowly, the lateral
one more broadly greenish eeneous ; a longitudinal stripe, angulate at
its middle, extends from the middle of the base to some distance
before the apex, the inner margin of this stripe is deeply concave at
the angulate portion; breast eneous ; abdomen more or less fulvous ;
legs flavous, the femora with a very minute tooth, the claws appen-
diculate, the inner division rather long and acute, the prosternum
broadly subquadrate, the anterior thoracic episternum convex.

This species, which I have only provisionally placed in Pheloticus,
has the general appearance and shape of a species of Rhyparida and ©
does not quite agree with any genus described under the group of
Typophorine, to which it undoubtedly belongs; the supra-ocular
sulcus is very narrow and placed close tg the inner margin of the
eyes, while the claws may almost be called bifid ; in one specimen,
probably the female, the thorax is still broader and subangulate at
the sides, and the femora and knees are stained with piceous.

Puetoricus(?) BIFASCIATUS, n. sp. (Plate XXXIX. fig. 3.)

Fulvous or obscure piceous, the head and thorax greenish, the
latter remotely but strongly punctured ; elytra strongly puuctate-
striate, fulvous; the suture narrowly, the lateral margin broadly, and
a straight discoidal stripe abbreviated before the apex, metallic
green.

Length 1 line.

Of the same shape as the preceding species and of similar structure ;
the antennz entirely pale fulvous, the thorax distinctly but not
closely punctured on the dise ; the elytra without a basal depression,
and with a broad and regular-shaped discoidal stripe, pointed at its

lower end and not extending to the apex, the lateral margins broadly
metallic green as far as the middle of the elytra, the femora with a
very minute tooth, slightly stained with piceous; everything else as
in P. @neicollis.

IvONGIUS NIGROMACULATUS, 0. sp. (Plate XXXIX. fig. 5.)

Testaceous, the head and thorax impunctate; elytra finely punctate-
striate, nearly impunctate near the apex, the extreme lateral margin
and a small spot below the middle black ; femora unarmed.

Length 1 line.

Of convex and subcylindrical shape, the head impunctate, without
any grooves or depressions, the clypeus not separated from the face,
its anterior edge concave, the eyes surrounded by a narrow sulcus ;
the antennz quite extending to half the length of the elytra, flavous,
the basal two joints thick and short, of equal length, the third and
following joints more slender, the terminal ones distinctly incrassate;
thorax nearly twice as broad as long, subcylindrical, the sides very
strongly deflexed, straight; the anterior margin straight, the
posterior one rounded and widened at the middle, the surface im-
punctate ; elytra slightly widened posteriorly, strongly convex, with
a very slight depression below the base, the shoulders prominent,
the surface finely punctate-striate, the punctures nearly obsolete
near the apex, the extreme lateral margin and a small spot placed
near the latter below the middle black ; underside and legs flavous,
the Jast tarsal joint and the claws stained with black; femora
unarmed, claws bifid; prosternum widened posteriorly.

This species resembles much in shape those of the genus Paria
and also of Syagrus; on account of the unarmed femora and bifid
claws, however, I have placed it in Ivongius ; in some specimens
the lateral elytral margin is of the flavous or testaceous ground-
colour.

RHEMBASTUS DIMIDIATICORNIS, i. Sp.

Fulvous, the sixth and seventh joints of the antennz black, thorax
distinctly punctured on the disc; elytra violaceous blue, distinctly
punctate-striate, the apex fulvous.

Var. a. Elytra flavous, the base, suture, and an oblique band at the
middle obscure fuscous.

Var. 6. Elytra entirely fulvous.

Length 1 line.

Of convex, subcylindrical shape; the head nearly impunctate,
fulvous; the clypeus not separated from the face; eyes emarginate,
widely separated, sulcate above their inner margin; antennz
scarcely extending to half the length of the elytra, fulvous, the
sixth and seventh joints black, the terminal ones distinctly
thickened, the first and second joints short, almost equal, the
second and third joints thinner, equal; thorax about one half
broader than long, narrowed in front, the sides nearly straight,
the surface finely and sparingly punctured on the disc only, fulvous ;
scutellum fulvous; elytra broader at the base than the thorax,

570 MR. M. JACOBY ON NEW [Nov. 1,

obsoletely depressed transversely below the base, rather strongly
punctate-striate, the punctures much finer posteriorly, the dise
violaceous, the extreme apex fulvous ; underside and legs fulvous ;
femora unarmed; claws bifid; prosternum dilated posteriorly.

This small species is principally distinguished by the colour of the
antenne and that of the elytra; the varieties do not show any
differences except in the colour of the upper surface; the unarmed
femora do not agree with the definition of Rhembastus, but neither
this genus nor Ivongius are well defined by the author, who has said
nothing about the sulcus at the sides above the eyes, nor does
M. Lefévre mention this character in his diagnosis of the genus. On
the other hand, Ivongius, which agrees in the unarmed femora with
the present species, is described by von Harold as having the clypeus
separated from the face, which is not the casein the insect described
here. Ivongius antennarius, Har., agrees very nearly with it (to judge
from a three-line description), but is described with a smooth thorax.
R. pusillus, Har., seems to be another closely allied species, but
differs in the colour of the antennz and of the head and thorax.

RHEMBASTUS ANTENNATUS, 1. Sp.

Reddish fulvous; antennee flavous, the sixth, seventh, and apical two
joints as well as the tarsi black ; thorax sparingly punctured ; elytra
finely and distantly punctate-striate.

Length 13 line.

Head impunctate, the eyes surrounded with a distinct sulcus, the
vertex with a longitudinal groove, clypeus not separated from the
face ; jaws black ; antenne extending to half the length of the elytra,
flavous, the third and fourth joints equal, the sixth and seventh and
apical two joints black, the latter distinctly thickened ; thorax one
half broader than long, the sides straight, the surface sparingly and
finely punctured at the disc, the sides impunctate; elytra convex,
without basal depression, finely punctate-striate, more distinctly
anteriorly than posteriorly, the shoulders with a deep depression
within ; femora dentate, tarsi black, claws bifid.

Principally distinguished from other nearly similarly coloured
species by the colour of the antennze.

EURYDEMUS METALLICUS, 0. sp.

Obscure piceous, the antennee and legs fulvous; above metallic
greenish or cupreous ; the head and thorax nearly impunctate, the
elytra deeply punctate-striate, the interstices more or less longitudin-
ally convex, femora dentate.

Length 13-2 lines.

Of rather elongate and parallel shape ; the head metallic greenish,
with a few punctures at the vertex ; the eyes large, rather closely
approached, their inner margin sinuate ; clypeus transverse, fulvous,
its surface rather depressed, its upper margin separated from the
face by a narrow transverse groove; antennz long and slender,
fulvous, the basal joint stained with piceous, the second joint half

the length of the third, the fourth slightly longer than the preceding
joint ; thorax about one half broader than long, the sides nearly
straight, the surface very little convex, impressed with a few very
minute punctures, visible only under a strong lens; elytra much
broader at the base than the thorax, metallic green or cupreous, the
sutural and lateral margins sometimes fulvous, the punctures very
deep and regular, the interstices rather convex, the apex much more
finely and distantly punctured ; underside piceous, the breast with a
metallic greenish hue, the legs fulvous; the femora with a distinct
tooth; claws bifid; prosternum broadly transverse.

RHYPARIDA STRIATICOLLIS, n. sp. (Plate XX XIX. fig. 7.)

Fulvous, the head and thorax piceous, the antennee fiavous ; the
seventh joint black ; thorax transverse, longitudinally strigose on the
disc; elytra fulvous, with basal depression, strongly punctured
anteriorly, nearly impunctate below the middle.

Length 17 line.

Vertex of the head convex with a few fine punctures, dark fulvous ;
eyes with a very narrow sulcus round their inner margin ; clypeus
separated from the face by a deep transverse groove, rugosely
punctured; antennee rather long, flavous, the seventh joint black,
the third joint much shorter than the fourth, the terminal joints
slightly thickened; thorax twice as broad as long, but slightly
narrowed in front, the sides strongly rounded, the anterior angles
rather prominent, the dise strongly and closely longitudinally strigose
from the middle to the base, the anterior portion sparingly punc-
tured, fulvo-piceous ; elytra with a deep depression below the base,
strongly punctate-striate, the punctures nearly obsolete below the
middle; underside fulvous; legs flavous; the femora with a very minute
tooth, claws bifid; the anterior thoracic episternum slightly concave ;
prosternum broadly subquadrate, strongly punctured.

I cannot find any differences whatever in regard to structural
characters to justify a separation of this species from Rhyparida, of
which, until now, no true species have been known from Africa.
The general shape and that of the thorax is the same, the thoracic
episternum is not in the least convex, the four posterior tibiz are
emarginate at the apex and the claws are bifid ; the peculiar striation
of the thorax will distinguish this species at first sight.

HEMYLOTICUS, D. gen.

Body elongate ; antenne filiform; eyes deeply notched; thorax
broader than long; elytra punctate-striate, the four posterior
femora toothed, their tibie emarginate at the apex; claws bifid,
the inner division very short ; prosternum bilobed ; mesosternum
quadrate, its base raised, truncate; the anterior margin of the
thoracic episternum convex.

This genus will enter the section Typophoring, Chap., from all
genera of which it differs in the bilobed posterior margin of the
prosternum and in the structure of the mesosternum.

572 MR. M. JACOBY ON NEW [Nov. 1,

HEMYLOTICUS GENICULATUS, 0. sp. (Plate XXXIX. fig. 6.)

Reddish fulvous; the antenne (the basal joints excepted), the
knees, apex of the tibiew, and the tarsi black ; thorax very sparingly
punctured ; elytra finely punctate-striate.

Length 3 lines.

Head with a few fine punctures ; the epistome broad, subquadrate,
scarcely separated from the front ; mandibles black; antennz
slender, filiform, the lower three joints fulvous, the rest black, the
fourth joint slightly longer than the third; thorax about one half
broader than long, the sides rounded, the anterior margin straight,
the surface rather convex, with a few fine punctures; elytra much
broader at the base than the thorax, without basal depression, very
finely punctate-striate, fulvous and shining like the rest of the upper
surface; underside coloured as above; the knees, the apex of the
tibiee, and the tarsi black.

A single specimen is contained in my collection.

NISOTRA NIGRITARSIS, 0. sp.

Oblong-ovate, dark fulvous, the antenne (the basal three joints
excepted) and the tarsi black; head and thorax nearly impunctate,
the latter with four longitudinal grooves; elytra extremely finely
and closely punctured.

Length 23 lines.

Head impunctate, transversely grooved betweenthe eyes, the frontal
elevations but slightly raised; palpi slender; antenne extending
a little beyond the base of the elytra, black, the basal three joints
fulvous, the seeond and third joints of equal length; thorax twice
as broad as long, the sides rounded, the angles acute, the disc with
a few scarcely perceptible punctures, the anterior and posterior
margins with a short perpendicular groove at each side; elytra
widened towards the middle, the shoulders slightly prominent, the
surface extremely finely and closely punctured ; underside and legs
fulvous, the tarsi black.

This species seems allied to N. spadicea, Dalm., but differs in the
extremely fine and not geminately-arranged punctation of the elytra
and in the black tarsi and larger general size.

NISOTRA KLUGII, 0. sp.

Black; the head, thorax, the anterior legs, and the posterior
tibiee fulvous ; elytra metallic green or purplish, very closely and
finely punctured ; antennz fulvous or with the last three joints black.

Length 22 lines.

Head impunctate, the frontal tubercles small, clypeus thickened ;
the autenne extending a little beyond the base of the elytra,
fulvous, the last three joints black, the third and fourth joints
equal, the terminal ones thickened ; thorax twice as broad as long,
fulvous, the sides slightly rounded, the surface extremely finely and
closely punctured, the anterior and posterior margins with a very
short and indistinct longitudinal depression near the sides; scu-

tellum fulvous ; elytra slightly widened at the middle, very closely
and more strongly punctured than the thorax, the interstices
obsoletely longitudinally costate at the sides, the shoulders promi-
nent; the breast and abdomen as well as the posterior femora
black ; legs falvous.

This species varies in having metallic green or purplish elytra; in
two specimens the antennz have the last three joints black, in one
they are entirely fulvous.

ASPHERA MADAGASCARIENSIS, Nl. Sp.

Fulvous, shining ; the antenne: (the basal two joints excepted),
the apex of the femora, and the tibie and tarsi black; thorax im-
punctate; elytra closely punctured and finely rugose.

Length 4 lines.

Head impunctate, deeply transversely grooved between the eyes ;
frontal tubercles transverse, distinct ; clypeus swollen; palpi black ;
antennz robust, black, the basal two joints fulvous, the terminal
joints rather flattened ; thorax nearly three times as broad as long,
the sides with a broad and reflexed margin, strongly rounded; the
disc uneven, depressed at the sides and at the middle, impunctate,
shining ; elytra closely punctured, the interstices everywhere finely
wrinkled and rugose ; the apex of the femora and the tibiz and tarsi
black, tibize deeply channelled ; the first joint of the posterior tarsi as
long as the following joints together, claws moderately swollen.

Apparently allied to 4. melanarthra, Fairm., but differing in the
colour of the legs and the wrinkled elytra, also in having but two
joints of the antenne fulvous; M. Fairmaire describes his species
as having fuscous legs (femora 3-4 excepted) (?), which is (probably
through a misprint) unintelligible.

ASPHERA BREVICORNIS, 0. sp.

Flavous; the head, thorax, and legs pale fulvous; antenne (the
basal four joints excepted) black, short; thorax impunctate; elytra
very minutely and closely punctured.

Length 3 lines.

Head impunctate, the frontal tubercles transverse, nearly con-
tiguous ; clypeus raised, short and truncate at the raised portion ;
labrum, jaws, and palpi fulvous ; antennz only extending to the base
of the elytra, black, the basal four joints fulvous, the third joint
slightly shorter than the fourth, terminal joints thickened ; thorax
more than twice as broad as long, rather strongly narrowed in front,
the sides slightly rounded, narrowly marginate, the anterior angles
rather strongly produced and thickened, the surface impunctate,
shining, fulvous, rather deeply longitudinally sulcate near the
lateral margins; elytra pale flavous, very finely and closely
punctured ; legs fulvous; the first joint of the posterior tarsi as
long as the following joints together ; claws very slightly incrassate.

This species has nearly simple, that is scarcely swollen, posterior
claws, but agrees in all other respects with Asphera.

CEDIONYCHIS CLYPEATA, 0. sp.

Flavous; the antenne (the lower four joints excepted) and the
tarsi black ; clypeus strongly produced ; thorax impunctate ; elytra
scarcely perceptibly punctured, obscure fulvous.

Length 23 lines.

Head impunctate, the frontal tubercles entirely absent, the space
between the eyes deeply excavated ; the clypeus produced, flattened
and truncate at the apex; the antenne extending to about half the
length of the elytra, black, the lower four joints fulvous, the basal
joint widened, nearly subquadrate and short, the second one half the
size, the third and fourth equal, the terminal joints slightly
thickened; thorax strongly transverse, not narrowed in front, the
sides rounded, with a distinct flattened margin, the anterior angles
pointed, the disc unevenly raised at the sides, with several de-
pressions, entirely impunctate ; elytra minutely punctured, darker
than the thorax; legs flavous; the knees and the tarsi black ;
posterior claw-joint strongly swollen, black.

This differs from all the Madagascar species of Cdionychis
described in the structure of the clypeus and head, ec.

DipHAvuLAcosoMa, n. gen. (Halticine).

Body ovate; palpi thickened; antennz robust and short, the
terminal four joints dilated and compressed; thorax transverse,
without depressions, the sides strongly dilated and widened at the
middle, constricted at the base; scutellum subquadrate, its apex
truncate; elytra narrowed and subacute at the apex, obsoletely
punctured, their epipleurze extending below the middle; femora
robust, the posterior ones thickened ; the tibice not channelled, the
posterior ones with a spine; the first joint of the posterior tarsi
as long as the following two joints together ; claws appendiculate ;
prosternum narrow, convex; the anterior coxal cavities open.

The genus here proposed is principally distinguished by the
dilated terminal joints of the antennz and by the peculiar shape of
the thorax, which is strongly widened and rounded at the middle,
in connection with the open cavities. Spherophysa, Baly, also in-
habiting Madagascar, has the antennz likewise dilated; but this
dilatation is not confined to the terminal joints ; the body in Sphe-
rophysa is also strongly rounded, not ovete, and the coxal cavities
are closed.

DIpHAULACOSOMA LEVIPENNE, n. sp. (Plate XXXIX. fig. 8.)

Entirely fulvous, shining; terminal four joints of the antenne

Head impunctate ; the frontal tubercles oblique, distinct, bounded
behind by a transverse groove; the clypeus with a short central
ridge ; penultimate joint of the palpi thickened ; antenne only ex-
tending a little beyond the base of the elytra, fulvous, the terminal
four joints black ; thorax twice as broad as long, dilated at the sides,

the latter strongly rounded at the middle, the posterior angles pro-
duced into an acute tooth, the surface rather convex, transversely
depressed at the base, entirely impunctate ; elytra strongly narrowed
posteriorly, fulvous, shining, impunctate, or exceedingly finely and
sparingly punctured, the interstices very finely wrinkled here and
there.

The shape of the thorax is peculiar in this species, and the
posterior angles are distinctly dentate, the tooth being placed above
the middle line of the posterior margin, the angles themselves
being obliquely shaped.

MALACOSOMA STKOR&, 0. Sp.

Piceous ; the antenne and the labrum fulvous; thorax finely
punctured ; elytra more closely punctate, the punctures arranged in
closely approached rows.

Length 2-23 lines.

Head impunctate, the frontal tubercles transversely oblique, the
clypeus strongly triangularly raised ; labrum pale fulvous ; palpi
slender, piceous; antennze extending to half the length of the
elytra, pale fulvous, the joints very slender, the third and fourth
equal ; thorax subquadrate, about one half broader than long, the
sides nearly straight or slightly angulate before the middle (9 2),
the anterior angles distinct, furnished with a single hair, the surface
distinctly but not very closely punctured, piceous; elytra with a
very slight depression below the base, closely and scarcely more
strongly punctured than the thorax, the punctures arranged in
closely approached semi-regular rows; legs more or less fulvous ;
tibie mucronate, the first joint of the posterior tarsi as long as the
three following joints together ; prosternum narrowly raised.

The two specimens before me show some differences which are
probably sexuel: in one the thorax is less transverse, with nearly
straight lateral margins, and the elytra have a slight purplish gloss
and are more irregularly punctured; in the other specimen the
thorax is broader and the sides are distinctly subangulate before the
middle, the elytra have no metallic gloss and are more regularly
and less closely punctured in rows; both specimens, however,
apparently represent the same species ; the last abdominal segmeut
in both is simple.

Head with a more or less distinct depression at the vertex, the
latter with a faint metallic hue, impunctate ; labrum black ; antennze
as long as the body, very slender, black, all the joints with the ex-
ception of the second very elongate ; thorax short, without a distinct
lateral margin, the surface impunctate, with some shallow transverse
depressions, testaceous ; scutellum black; elytra bright metallic
green, finely transversely rugose, and closely punctured.

Closely allied to A. pulchella, Duviv., but differing in the pale
head, the absence of the green thoracic margin, the entirely green
elytra, and the black abdomen.

ANTSIANAKA LONGICORNIS, Duviv.

I refer a single specimen to this species; my specimen differs,
however, from the description in having an entirely testaceous head.
M. Duvivier does not mention the colour of the antenne, which
are fuscous in my specimen with the basal two joints black.

Pale flavous; antenne (the basal two joints excepted) black ;
elytra metallic blue, narrowly margined with flavous, rather strongly
punctured ; the interstices finely transversely rugose.

Smaller than any of its allies, the antenne extending beyond the
elytra, entirely black, with the exception of the first two joints,
which are flavous; the head swollen, impunctate; the thorax very

short, transversely depressed above and impuactate. Elytra narrowly
margined with flavous, much more distantly punctured than 4.
pulchella, Duv., and the interstices much less strongly rugose, finely
wrinkled transversely, and without traces of longitudinal cost. The
thorax also is entirely flavous like the head.

/ELIANUS, n. gen. (Galerucine.)

Body elongate ; antennz rather robust, the second and third joints
short, the following gradually elongate; thorax transverse, the anterior
angles more or less produced; elytra irregularly punctured, their
epipleurz narrow but continued below the middle ; tibize mucronate,
the first joint of the posterior tarsi nearly as long as the following
joints together ; claws appendiculate ; the anterior coxal cavities open ;
prosternum not distinct.

This genus approaches closely Malacosoma in general shape and
structural characters, but differs in the longer first joint of the
posterior tarsi and in the scarcely visible and not convex prosternum.
The female insect differs rather considerably from the male, the
antenne are shorter, the apical joints being much less elongate, and
the anterior angles of the thorax are thickened and produced.

ABLIANUS SCUTELLATUS, n. sp. (Plate XX XIX. fig. 9.)

Obscure piceous ; the head, antennz, the scutellum, and the tarsi
black ; above testaceous, thorax impunctate, spotted with black or
without spots; elytra very minutely punctured; legs obscure
fulvous, stained with picecus.

Length 22 lines.

6. Head shining, impunctate, black, the frontal elevations
strongly raised, the clypeus with a distinct central ridge, obscure
fulvous ; palpi slender, piceous; antennz extending to half the
length of the elytra, black, the third joint slightly longer than the
second, the following five joints equal, the others more elongate, the
terminal joint half the length of the preceding one; thorax twice as
broad as long, the sides nearly straight as well as the anterior margin,
the posterior margin obliquely rounded at the sides; the anterior
angles slightly thickened, the extreme lateral margin black ; the disc
flavous or testaceous, impunctate, with four piceous spots placed
transversely, the outer ones being the largest ; scutellum large, black,
shining; elytra testaceous, the extreme sutural margin narrowly
piceous, the disc finely and closely punctured, rather opaque ;
underside and legs obscure fulvous or piceous, finely pubescent, the
tarsi black ; the last abdominal segment deeply excavate, incised at
the sides.

Q. The antenne shorter, all the joints (the second one excepted)
of nearly equal length, rather thickened; thorax with the anterior
angles strongly thickened and produced outwards, the last abdominal
segment simple.

following elongate, gradually diminishing in length; thorax trans-
verse, short, the sides nearly straight; elytra irregularly punctured,
their epipleurze very narrow, entirely disappearing below the middle ;
legs slender ; all the tibiz with a spine, the first joint of the pos-
terior tarsi as long as the following three joints together; claws
appendiculate ; prosternum invisible between the coxe, the anterior
coxal cavities open.

The insect for which this genus is proposed has the general
appearance of the species forming the genus Mimastra, from which
it is distinguished by the mucronate tibie; the narrow epipleura,
invisible below the middle, and the spines on all the tibiz separate
the genus from Luperus.

MIMASTROIDES MADAGASCARIENSIS, n. sp. (Plate XXXIX.
fig. 11.)

Obscure testaceous, the base of the head, the labrum, antenna,
the upperside of the femora, and the tibiw and tarsi black ; thorax
and elytra testaceous, closely semi-rugosely punctured.

Length 3 lines.

Head finely and sparingly punctured on the vertex, the basal
portion blackish, the frontal elevations small but distinct, the clypeus
triangular, raised, yellowish ; labrum and palpi black; eyes very
large; antennz about half the length of the body, black, the first
joint elongate, thickened at the apex, the second one short, the third
and fourth slender, equal, the apical joints shorter ; thorax twice as
broad as long, the sides straight, the anterior angles thickened and
slightly oblique, the posterior angles in shape of a small tubercle,
the surface flat, closely punctured, the interstices slightly rugose ;
scutellum obscure piceous, broad ; elytra without basal depression,
punctured like the thorax, obscure testaceous ; breast slightly darker,
the upper portion of the femora, the tibiee, and tarsi black ; the apex
of the last abdominal segment triangularly emarginate.

GALERUSOMA, N. gen.

Elongate, impubescent. Head produced, eyes entire; palpi slender ;
antennee filiform, the first jomt very long and the longest; thorax
subquadrate, scarcely broader than long, the surface flat without
depression ; scutellum rather broad ; elytra wider at the base than
the thorax, elongate, irregularly punctured, their epipleurz narrow,
disappearing below the middle; legs slender; tibize unarmed, the
first joint of the posterior tarsi as long as the following three joints
together ; claws bifid ; the anterior coxal cavities closed.

This genus, in its elongate and slender shape, resembles somewhat
the genus Mimastra; its principal distinguishing characters are the
very long and slender first joint of the antenne and the bifid claws,
which separate the genus also from Mimastroides.

GALERUSOMA APICICORNE, N. sp.

Fulvous, the lower and the apical three joints of the antenne, the
tibize, and tarsi black; thorax very minutely, elytra more strongly
and very closely and irregularly punctured.

The following report from the Secretary on the additions to the
Menagerie during the month of October was read :—

The registered additions to the Society’s Menagerie during the
month of October were 135 innumber. , Of these 104 were acquired
by presentation, 14 by purchase, 1 by birth, 1 by exchange, and 15
were received on deposit. The total number of departures during
the same period by death and removals was 121.

The most noticeable additions during the month were :—

1, A very fine male Ostrich (Struthio camelus), presented by
Her Majesty The Queen, and received October 7th.

This is one of the largest Ostriches we have ever had. It
measures 4 ft. 10in. in height at the back, and about 4 ft. 3 in. in
total length, whereas the male now next to it in the Gardens, which
we obtained from the Zoological Society of Antwerp in May last,
measures only 3 ft. 8 in. in height and about 2 ft, 2 in. in length.

580 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. [Nov. 15,

The latter (originally received from Oran, Algeria) is no doubt of
unusually small dimensions.

The ‘‘Queen’s Ostrich” was procured by Mr. Williams, of
Sierra Leone, during a recent expedition to the dominions of King
Samory (or Samadou), about 700 miles in the interior from Free-
town’, in the basin of the Upper Niger, for Mr. Alfred L. Jones of
Oaklands, Aigburth (at whose expense the expedition was organized),
and offered by Mr. Jones as a present to Her Majesty The Queen,
who was graciously pleased to deposit it in the Society’s Gardens.

The colour of the naked skin on the neck and legs of this bird is
reddish. In the Somali bird (Struthio molybdophanes, Reichen.”)
it will be recollected that these parts are bluish. But the various
geographical subspecies of the Ostrich have not yet been properly
discriminated.

2. A specimen of what appears to be a new and undescribed
Monkey of the genus Cercopithecus, obtained by Dr. Joseph A.
Moloney at Chindi, on the Lower Zambesi, when returning to this
country in company with Stairs’s expedition. It is at once
recognizable, as will be seen from the coloured figure by Mr. P. Smit,
which I exhibit, by the strongly marked chestnut-red patches above
the ears.

I propose to call it

I propose to dedicate this distinct species to the memory of
Lieut. W. Grant Stairs, of the Royal Engineers, who died at Chindi,
at the mouth of the Zambesi, on June 9th, 1892, on his return from
his expedition to Katanga. The typical specimen was obtained
from the delta of the Zambesi by Mr. Hellier, the British Central-
African Company’s Agent at Chindi, and given to Dr. J. A. Moloney,
one of the surviving members of Stairs’s expedition, who brought it
home and presented it to this Society.

3. A large series of specimens of Mammals, Birds, and Reptiles,
brought back by Mr. Frank Finn, F.Z.S., on his recent return from
a zoological excursion to Zanzibar. These animals were given into
Mr. Finn’s charge by General Mathews, C.M.G., Dr. W. H. B.
MacDonald, Mr. R. MacAllister, Mr. F. Pordage, and other Corre-
spondents of the Society at Zanzibar and Mombasa. Amongst

Black Gallinule (Limnocorax niger), the Madagascar Pratincole
(Glareola ocularis), Grant’s Francolin (Francolinus granti), and
of other species new to the Society’s collection.

4. Two Ypecaha Rails (Aramides ypecaha) from Brazil, pur-
chased Oct. 24, new to the Society’s collection.

The Secretary exhibited, on behalf of Mr. Thomas Ground, a
specimen of the Siberian Pectoral Sandpiper (Tringa acuminata),
shot by that gentleman on Breydon mudflats, in Norfolk, in
August last*, and read the following letter addressed to him on this
subject :—

“School Lane, Moseley,
’ Birmingham,
Noy. 14th, 1892.
“ Dear Sir,

“T have sent you to-day by L. & N. W. passenger train the
specimen of Tringa acuminata for exhibition at the meeting of your
Society tomorrow evening.

“J shot the bird on the 29th August last on Breydon mudflats ;
it was in company with a Ringed Plover and three or four Dunlins.
The boatman picked it up and threw it into the punt, saying it was
a Dunlin. On reaching home I examined the bird, and having
never seen a Dunlin with so fine and short a bill, I took it to the
stuffers and was agreeably surprised to find a few days afterwards
that it had been pronounced to be an example of 7. acuminata.

“Yours faithfully,
“Tos. GrounD.”

For the purpose of comparison with this specimen Mr. Thomas
Southwell had, with the permission of the Trustees of the Norfolk
and Norwich Museum, kindly sent up the specimen of Tringa
acuminata purchased by the late J. H. Gurney in 1848, and at first
referred to Tringa pectoralis”.

Mr. Southwell wrote that since the specimen was recognized
as Tringa acuminata it had been restuffed for the Museum by
Mr. Roberts, who was decidedly of opinion that the specimen had
been originally (that is when stuffed by Knights) set up from the
flesh. It had been badly shot in the neck and legs.

Mr. G. A. Boulenger, F.Z.S., read a paper describing the remains
of an extinct gigantic Tortoise from Madagascar (Testudo gran-
didieri, Vaill.), based on specimens obtained in caves in South-west
Madagascar by Mr. Last, and transmitted to the British Museum.
The species was stated to be most nearly allied to Testudo gigantea
of the Aldabra Islands.

This memoir will be published entire in the Society’s ‘ Transac-
tions.’

582 MR. 0. THOMAS ON A NEW SEMNOPITHECUS. [Nov. 15,

1. Description of a new Monkey of the Genus Semno-
pithecus from Northern Borneo. By Oxpriretp THomas.

[Received October 25, 1892.]
(Plate XLI.)

In 1889 I had the pleasure of describing before this Society’ a
very beautiful species of Semnopithecus from the Baram district,
North-eastern Sarawak, which was discovered by Mr. Charles Hose,
and was named in his honour Semnopithecus hosei. Of this Monkey
many specimens, all from much the same district, have come to
Europe, and I have reason to believe that most of the European
Museums are now supplied with examples of it, all obtained by the
same energetic and successful collector. In our own Museum we
have, besides the type, another adult male, two young specimens,
and an adult skeleton. All these specimens, including young ones
barely a foot in length, have shown the most striking uniformity in
their coloration, there being in none of them the smallest deviation
from the colour depicted in my illustration of the type (é. ¢.
plate xvi.).

Now, however, the Museum has received, first from Mr. A.
Everett, who noticed the differences himself, one specimen, and then
from Mr. Hose two more, of a Monkey undoubtedly closely allied
to S. hoset, but yet all three so like each other and so different in
markings from any specimen of that species which I have seen, that
I feel unable to consider it to be S. hosez, and therefore must
describe it as new.

Mr. Everett’s specimen having been the first obtained, I propose
to make it the type, and to name the species in honour of its
discoverer, who, as already mentioned, had himself noticed its
distinguishing characters.

SEMNOPITHECUS EVERETTI, sp.n. (Plate XLI.)

Size and proportions as in S. hosei. Colour of body, limbs, and
tail as in that species except that the white is everywhere replaced
by dull cream-colour, and this change produces a marked yellowish
suffusion in the mixed grey of the back and tail; the shoulders and
the centre of the back are also darker, a character still more marked
in the two Dulit specimens than in the type. Belly and the light
parts of the head pale yellowish or cream-colour, quite different
from the snowy white of S. hosci. The chief difference, however,
lies in the distribution of the colours of the head, for while in
S. hosei only the centre of the crown and a narrow line down the
nape are black, the rest, including the whole of the region round
and above the ear, being pure white, in 8. everetti the whole of the
forehead and top of head are black, the lower limit of the black
passing across the middle of the ear, and the whole breadth of the

back of the neck is also black. A spot in the exact centre of the
forehead just above the meeting of the eyebrows is, however, pale
yellowish white. The pale cheeks and the pale sides of the neck
are in this species in just as striking contrast to the dark crown as
in S. hosei, and distinguish it equally from its near ally S. chryso-
melas.

In the skull the differences are of course but slight, and many
specimens of each would be needed before any of them could be
claimed as genuinely differential characters. Comparing the type
skull of S. everetéi with that of S. Aosei, the brain-case is longer
and more flattened, the orbits are more circular in outline, and the
length of the zygomata is decidedly greater. The development of
the fifth cusp to the last lower molar is very much the same in
both, i.e. much less than in S. cristatus and the majority of the
species, but much greater than in S. chrysomelas, a species remark-
able for the almost entire suppression of the cusp.

Dimensions of the type, an adult female in skin :—Head and body
(c.) 550 millim., tail 650.

Skull—basal length 63:7, greatest length (gnathion to occiput)
94, greatest breadth 70, combined length of upper premolars and
molars 24, of molars only 16:2.

The type specimen was obtained by Mr. Everett’s hunters at an
altitude of about 3500 feet on Mount Kina-balu, in March 1892.
Mr. Hose’s two specimens were killed at 3000 feet on Mount Dulit in
June. The species is therefore no doubt a purely mountain one,
and does not, like S. hosei, descend to the plains. This latter
species, however, also occurs at considerable altitudes on Mount
Dulit, but has not as yet been certainly found on Mount Kina-balu,
the skull from that mountain doubtfully referred by me to it in
1889 ' belonging very probably to S. everetti.

Finally, I must of course admit the possibility of intermediate
specimens between S. hosei and S. everetti occurring, and the con-
sequent necessity for the reduction of the latter form to the rank of
a subspecies; but in the absence of such intermediate forms and in
view of the great constancy in the coloration of S. hoset already
noted, it seems best to give a name to the striking variation from it
now described.

584 MR. G. A. BOULENGER ON A NEW BLENNIOID Fisul. [Nov. 15,

Gill-membranes broadly connected, but free from isthmus ; branchio-
stegals four. Dorsal fin very long, extending from the nape to the
caudal, with which it is subcontinuous ; a few of the posterior rays
are stiff spines, the rest being soft, though not articulate; anal fin
extending from the anus, which js a little nearer the anterior than
the posterior extremity, to the caudal, formed exclusively of soft
rays; caudal distinct, rounded. Pectorals well developed, with 21
rays. No ventrals. No lateral line. No prominent anal papille.
Pyloric appendages present.

As the name I have chosen for this genus indicates, this is one of
those numerous forms which might almost equally well be referred
to the Blenniide or to the Ophidiide. The presence of pyloric
appendages and the absence of prominent anal papillee might induce
us to include it among the Gadoids, as defined by Giinther, whilst

the presence cf spines in the dorsal fin, together with the un-

to be among the Blenniide.

in opposite direction, from the eye to the opercle; two dark brown
streaks across the nape, the second crossing the origin of the dorsal
fin and extending to the base of the pectoral; dorsal and caudal

paulovski harbour, Kamtschatka, on Sept. 8, 1891. Before describing
this fish as new I have satisfied myself, by a careful comparison
with the original description, that it cannot by any means be
referred to Ophidium ocellatum, Tilesius, which it strongly resembles
in general appearance. Notwithstanding the several different names
which have been bestowed upon it, this Ophidium ocellatum, ob-
tained at Petropaulovski, has not been rediscovered since its descrip-
tion in 1811, and its affinities are altogether uncertain.

3. On some cases of Variation in Secondary Sexual Characters,
statistically examined. By W. Baresson, M.A., Fellow
of St. John’s College, Cambridge, and H. H. Brinpuey,
M.A., St. John’s College, Cambridge.

[Received November 15, 1892.]

It is a familiar fact that many insects are provided with long,
chitinous horn-like processes of various shapes and forms. Such
horns are sometimes present in both sexes, but more commonly
they attain their chief development in the male only. Among
beetles the most striking examples are found in the Lamellicorns,
many of which have horns of great size on the head, or on the
thorax, or on both. Analogous developments are seeu in the great
mandibles of the males in some Lucanide, of which the Stag-beetle
(Lucanus cervus) is a common representative. In the majority of
these forms the similar parts of the females are either not produced
at all or are much smaller. Now in many species having these
curious horns in the male sex, it has long been observed that the
males are not all alike in the degree to which the horns are devel-
oped; but that, on the contrary, some of the males may bear
massive horns of prodigious size, while other males of the same
species have hardly any horns at all, being in fact very like females.
The males with the great horns are in common parlance known as
“‘high”’ males, those with the rudimentary horns being “ low ”
males. A good series of figures illustrating the phenomenon is
given by Darwin’, and examples of such Variation in Odontolabis
&c. are exhibited in a show-case in the Natural History Museum
at South Kensington.

The phenomenon of great Variation in the development of horns
present in the males as a secondary sexual character is not peculiar
to beetles, though in them it perhaps reaches a climax. A similar
case is presented for instance by the Common Earwiz (Forficula
auricularia), in which the terminal foreeps are in some males no
larger than those of the female, while in others they are three times
the size.

’ «Descent of Man, 1871, yol. i. pp. 368-375.

586 MESSRS. BATESON AND BRINDLEY ON [Nov. 15,

The investigation we proposed to ourselves was as follows.
Taking a species in which the horns of the male are sometimes
small and sometimes of great size, we wished to see if individuals
having any one degree of development of horns are more frequent
than those having other degrees of development. The high males
are an extreme form, and the low males are again an extreme form:
would it then be found, on inquiry, that the mean form between
these two is the commonest ?

To those who are acquainted with the statistics set forth by
Galton in ‘Natural Inheritance’ and elsewhere, it will be well
known that measurements of certain quantities, as, for example,
those of the stature of Englishmen, group themselves around a
mean form in such a way that the curve representing the frequency
of occurrence of the several measurements has the form known as
a curve of Frequency of Error. In other words, there is a mean
stature for that group of persons, and variations from this mean are
rarer in proportion as they depart from it. Persons of mean stature
are common, while the tall and the short are rarer. This group of
individuals may then be described as monomorphic in respect of
stature. If, on the other hand, it were found that tall persons were
common and short persons were common, but persons of middle
height were rare, such a group might be called dimorphic in respect
of stature, and the curve representing the frequency of their various
statures would not form one Curve of Error with one peak, but would
have ¢wo peaks. In two of the three examples about to be described,
the statistics showed that such dimorphism does actually exist, and
that it is not the mean form which is the commonest, but rather the
moderately high and the moderately low. After these remarks we
may now describe our observations.

I. Forricuta auricutaria. (The Common Earwig.)

In a visit to the Farne Islands off the coast of Northumberland it
was noticed by one of us that these small rocks were inhabited by
vast quantities of Earwigs. ‘The Farnes are a group of basaltic
islands about 3-5 miles out to sea, few of them having human
habitations. ‘They are a well known breeding-place for sea-birds of
many kinds. Above high-water mark most of the rocks are covered
with a deep, black vegetable mould in which Silene maritima grows
luxuriantly, constituting the chief vegetation, and it is in this that
the burrows of the Puftins are for the most part made.

The abundance of Earwigs was most extraordinary. Under every
stone or tussock there was an almost continuous sheet of Earwigs.
This was the case not only among the sea-birds’ nests, but also
round the light-keepers’ houses where no birds build. It did not
seem, therefore, that the excessive quantity of Earwigs was necessarily
connected with the presence of the nests.

It was at once seen that amongst these Earwigs were many males
with extremely long forceps, like that shown in fig. 1, Il. The
usual form is seen in fig. 1, I, both figures being natural size. We

tively.
It appears that the high male is known from many places in

England and elsewhere, and that it was made into a distinct species
by Stephens! under the name F. forcipata. This species has not
been retained by later authorities (see Fischer? and Brunner von
Wattenwyl’). After the visit to the Farnes, the high males were
found on the mainland near Bamborough in fair quantity, though
not so abundant as on the Farnes. We have received also a large
sample of Earwigs collected in a Cambridge garden, containing 163
males, of which 5 would come into the “thigh” class, A
sample kindly collected for us by Dr. Norman, F.R.S., in his garden
at Burnmoor, near Durham, contains no high male. The great
abundance of high males at the Farnes seems to be quite excep-
tional.

With a view to determining the frequency of the high and low
forms, 1000 of these Earwigs were collected for us by Miss A.
Bateson on Sept. 12, 1892. The whole were taken in one day from
three very small islands known as the Knocksies and Widerpern,
which are joined to each other at low tide.

Of the 1000 specimens 583 proved to be mature males. Before
giving the results of the measurements, it is perhaps necessary to
give the reasons upon which we believe these specimens to have been
all adult. In this matter we rely partly on the judgment of
Dr. Sharp, F.R.S., who has most kindly assisted us in many ways
throughout this investigation, and was so good as to take part in
the work of measurement. We are informed by Dr. Sharp that the
full development of the elytra is only reached in the adult state in
F, auricularia, and we have been careful to include no specimen
having imperfect elytra. As may be seen in the figures, the develop-
ment of the elytra in the high and low males is the same. Besides

this, it is to be remembered that in most localities the high male
is either unknown or very scarce, and it cannot be doubted that in
these places the low males are really mature. Lastly, we know by
the analogous case of horned beetles that high males coexist with
low males, both being in this case of course mature. We think,
therefore, that we are justified in considering that the 583 males
available for measurement were all adult.

These specimens were laid out on squared millimetre paper
covered with gum, and while the gum was still wet the posterior end
of the forceps was brought up to one of the lines, and the length of
the forceps was read to the nearest half millimetre, which is well
within the limit of error. The results are set out in the accompany-
ing curve (fig. 2), in which the figures on the ordinates denote

Earwigs (Ff. auricularia).

numbers of individuals, those on the abscissze denoting millimetres.
The smallest length of forceps was 2°5 mm., and the greatest 9 mm,
As the curve shows, the greatest frequency is grouped about 3°5
mm. and 7 mm. respectively. The mean form, having forceps of
moderate length, 4-6 mm., is comparatively rare. We consider that
the number of cases is enough to justify the acceptance of these
statistics, and it is unlikely that a greater number of cases would

much alter the shape of the curve’. The size of the forceps in the
females searcely varies at all, probably less than 1 mm. in the whole
sample.

It is perhaps unnecessary to say that this result is of considerable
importance to an appreciation of the way in which Variation may
occur. There is here a group of individuals living in close com-
munion with each other, high and low, under the same stones. No
external circumstance can be seen to divide them, and yet they are
found to consist of two well marked groups, containing about equal
numbers. To those who are acquainted with the chapter on Organic
Stability in Galton’s ‘ Natural Inheritance,’ this will be recognized
as an instance of Variation about two positions of stability, the
intermediate position being one of less stability. In the common
language of naturalists, the facts of this case suggest that there is,
for some wholly unknown reason, a dimorphism among the males of
these Earwigs, maintained though all live together. In cases of
dimorphism some have thought fit to speculate on the possible
utility of the phenomenon. We know no basis of fact from which
these discussions may be properly attempted, and we leave these
matters to those who are satisfied with such methods of biological
inquiry and have leisure and ingenuity to pursue them.

For the present we are content to recognize that in this case of
the Earwig there is evidence of a definite and partially discontinuous
Variation, in respect of a secondary sexual character.

II. XyLorTrvuPeEs GIDEON.

We are indebted to Baron A. von Hiigel for a large supply of
this species. They were collected by him at a height of 4000-5000
feet in the Willis Mountains, Kediri, Java, in February to April, 1878.
In fig. 3 (p. 590) the males of this species are represented. As there
seen, in this sex two horns are present, the one produced from the
head, the other from the thorax. The two horns lie in the same
vertical plane, and each ends ina smallfork. Taken together, these
two horns thus constitute a pair of forceps, which can be opened by
depressing the head. The points of the forceps do not exactly
meet, but the point of the cephalic horn in high males is overlapped
by that of the thoracic horn. As the figures show, there is very
great variation in the degree to which these horns are developed in
the male, the three drawings representing “ high,” ‘‘medium,”’ and
“low” males respectively. In the female neither horn is developed,
but there is considerable variation in total length. As may also be
seen in the figures, those males which have very large horns are

1 In most insects having high and low males, the high males are large in
every way, while the low males are small. That this is so, generally speaking,
in these Harwigs was clear, but it is not possible to get reliable measurements of
total length, owing to the fact that the abdominal segments “ telescope ” into
each other. Hence no examination of the correlation between total length and
the length of the forceps could be attempted. There is nevertheless no doubt
that the ratio of the length of the forceps to the total length is higher in high
males than in the low.

Proc. Zoou. Soc.—1892, No. XL. 40

590 MESSRS. BATESON AND BRINDLEY ON [Nov. 15,

also in other ways large individuals, while the males with small
horns are small individuals. But though there is some correlation
between absolute size and the degree to which the horns are devel-
oped, our measurements have shown that this correlation is not
perfect. It is of course clear that the ratio of length of the horns
to that of the body is greater in the high males than in the low.
Baron von Hiigel gave us some interesting particulars as to the
natural history of these beetles. They were collected in the height
of the breeding-season, perhaps the greater number being found
coupled. It was noticed that large males were often attached to

small females and the reverse, but there appeared to be no regularity
in this. In view of the circumstance that there are scarcely any
observations as to the functions of the horns of beetles, the following
statements of Baron von Hiigel are especially noteworthy. He says
that the animals were caught by himself and by natives, and were
tied up with pieces of bast. When they were brought home and
untied, the males immediately sought out the females, and seizing
them transversely, carried them about, held between the two horns,
with evident satisfaction. He tells us that this was observed again
and again, and was clearly a definite habit. The males with small
horns, though unable to lift the females, nevertheless made ludi-
crous efforts to do so. In answer to the question whether it was
observed that these small males did not succeed in obtaining females

1892.] VARIATION IN SECONDARY SEXUAL CHARACTERS. 591

in the state of nature, Baron von Hiigel tells us that he has no
reliable recollection on this point.

The habit described above is not confined to X. gideon, for
Baron von Hiigel observed it also on one occasion in the case of
Chalcosoma atlas, the well-known Atlas-beetle. A pair of this
species from Java were presented by him to the Cambridge Museum,
which were thus found, the female being carried between the horns
of the male. In view, therefore, of the fact that the horns of many
species are in various ways disposed as a pair of forceps, it is possible
that this may be a habit widely spread; but that such a function
cannot be attributed to all the cases of horns is shown by the fact
that in many species the horns do not form a pair of forceps.

In 342 males of this beetle the cephalic horn was measured with
compasses from the angle of the terminal fork to the edge of the ridge
into which the horn is proximally and ventrally reflected, just in front
of the eyes. The results obtained are tabulated in fig. 4, according

specimens were few, while the moderately high and moderately low
males are common, the two groups being about equ: lly numerous.

Measurements of the thoracic horn showed a similar dimorphism ;
but, for the reason that it is not possible to measure this horn apart
from the thorax, these measurements are not so satisfactory.

The length of the elytra was also measured, and it may perhaps be
taken as a measure of the body-length. For various reasons it is
hard to obtain any more satisfactory measurement of the body-length.
Such a measurement must either include the variable horns or else
must depend on the degree of flexion of head or thorax. The result
of the measurement of the elytra is perhaps unexpected in view of
the knowledge that there is dimorphism in respect of the cephalie
horn. Fig. 5 shows the result of grouping the statistics as to the

frequency of the various lengths of elytra, and it is hence clear that
the mean form is the commonest, just as it is in the case of the
stature ofa given human community. Though dimorphic in respect
of the length of the horns, these males are thus monomorphic as
regards the elytra. There is of course nothing really contrary to

1892.] | VARIATION IN SECONDARY SEXUAL CHARACTERS. 593

expectation in the fact that a race is dimorphic in respect of one
character while in respect of another it is monomorphic.

III. Lucanus cervus. (The Stag-beetle.)

Of this insect we have no quantity of males sufficient to justify
a statement that in respect of the development of the mandibles it is
monomorphic or dimorphic. It is well known that very striking
differences are found between high and low males in this species.

Males to the number of 115 obtained at Woking in 1891 and 1892
have been measured. The lengths of the mandibles from the apex
to the internal angle between the base and the head were taken with
compasses, and the result is exhibited in fig. 6. The fact that this

sample is monomorphic is quite clear, for the numbers are plainly
grouped round the middlemost value. But in this case there is
serious reason to doubt whether the sample examined contains really
low males. In our experience of the Earwig’s forceps and the
Xylotrupes horns, the low males are almost like the females; but in
the case of the Stag-beetle the mandible of the lowest male seen
was much greater than that of the females. It seems possible that
in the Stag-beetle the truly low male is either very rare or does not
occur, and that the existing individuals belong to a group answering
to those which were found in Xylotrupes above the middlemost
value. There is in fact a possibility that we have in the Stag-beetle
a case which is the converse of that of the Earwig. In most places
the low male Earwig is to be found, the high male being absent or

594 DR. S.J. HICKSON ON ALCYONARIA STOLONIFERA. [Dec. 6,

very scarce, but in the Stag-beetle it is the high male that is
common while in most places the low male is absent or scarce.

In this case, and in that of X. gideon also, the ratio of the man-
dibles or horns to the total length is higher in the high males than
in the low males; or, in other words, though the body of a high
male is larger than that of a low male, the horns of the high male
are still larger in proportion to the body than those of the low male.

In conclusion we would call attention to the fact that fantastic
secondary sexual horns present one of the most difficult problems in
Evolution, for as to their modes of origin even guesses can scarcely
be made. To their production a considerable expenditure of energy
is clearly needed, and yet in many cases they have no obvious func-
tion. They are, further, notoriously variable. Darwin on the whole
was disposed to regard them as ornaments. The knowledge there-
fore that variation in the degree of development of these structures
may be discontinuous is a material assistance to the formation of
any conception as to the manner of their origin. The question may
be asked, does the dimorphism of which cases have now been given
represent the beginning of a division into two species, or rather a
division which might be accentuated so as to lead to such division ?
To this question we have no answer to make, but such a possibility
may well be remembered.

We must express our thanks to Messrs Macmillan for their
kindness in allowing us to use the drawings of figs. 1-4, which have
been prepared by them in illustration of a forthcoming book by one
of us on the subject of Variation.

The Secretary read the following report on the additions to the
Society’s Menagerie during the month of November 1892 :—

The total number of registered additions to the Society’s Mena-
gerie during the month of November were 144, of which 94 were by

Dr. S. J. Hickson, F.Z.S., read a paper entitled ‘A Revision of
the Genera of the Alcyonaria Stolonifera, with a Description of one
new Genus and several new Species,” of which the following is an
abstract :—

In a communication made to the Royal Society in 1883, the
author proposed to separate those Alcyonarians in which the polyps
spring independently from a creeping stolon into a suborder, the
Stolonifera.

The author’s views have not been accepted by von Koch, Viguie,

1892.] DR. S.J. HICKSON ON ALCYONARIA STOLONIFERA. 5Y5

Perceval Wright, aud Studer, but a renewed investigation of the
genera belonging to the suborder has convinced him that the pro-
posed classification is perfectly justified. The suborder Stolonifera
may be defined as follows :—

Colonial Alcyonaria with a membranous or ribbon-like stolon.
Mesogloea poorly developed. Polyps either entirely free from one
another except at their bases, or connected by horizontal platforms
(Tubipora) or connecting tubes (Clavularia viridis and the fossil
Syringopora). Skeleton composed of calcareous spicules which may
be joined together to form firm tubes, or free from one another, or
absent. In some cases the body-walls supported by a horny
secretion.

The suborder Stolonifera contains two families: Tubiporide and
Clavulariidee.

The family Tubiporide contains one genus: Zubipora.

The family Clavulariide contains four genera: Clavularia,
Cornularia, Stereosoma, and Sympodium, and probably Syringopora.

The genus Cornularia may be defined as follows :-—

Clavulariidee without spicules. Stolons with a simple cavity.
Polyps retractile. The basal parts of the polyps and stolon protected
by a horny secretion.

The genus Clavularia may be defined as follows :—

Clavulariide with a membranous or retiform creeping stolon
into which the polyps cannot be completely retracted. Spicules
usually present. No horny secretion of the ectoderm formed.

The genus Sympodium may be defined as follows :—

Clavulariidee with a thick plate-like stolon into which the polyps
may be completely retracted.

The genus Stereosoma may be defined as follows :—

Clavulariide forming small colonies, consisting of stiff non-
retractile polyps situated at considerable intervals from one another
on a thick plate-like stolon. Tentacles non-retractile. Pinne few
and widely separated from one another. Spicules absent.

Rhizowenia, Sarcodictyon, Anthelia, Gymnosarca, Cyathopodium,
and Cornulariella can no longer be retained as separate genera, as it is
impossible to separate them from the genus Clavularia. The species
of these genera therefore become species of Clavularia.

The following new species of Stolonifera are described :—

Stereosoma celebense, from the shore reefs of Talisse Island,
North Celebes.

Clavularia garcie, from Diego Garcia, shallow water.

Clavularia reptans, 5-20 fathoms off Talisse Island, N. Celebes.

Clavularia celebensis, shallow water, Talisse Island, N. Celebes.

The following species previously named by the author in the
Proc. Royal Society of Victoria are described in detail for the first
time :—

Clavularia ramosa.
Clavularia flava.

1. On the Convolutions of the Cerebral Hemispheres in
certain Rodents. By Franx E. Bepparp, M.A., F.R.S.,
Prosector to the Society.

[Received December 6, 1892.]

The Rodents are for the most part smooth-brained animals ; there
are, however, several exceptions to the universal applicability of this
statement, which have been to some extent dealt with by previous
writers, including myself. The Rodent brain has not, however,
been subjected to that careful study to which the Ungulate and
Carnivorous brains have in the hands of Dr. Krueg and Prof. Mivart.
The only paper dealing with the Rodent brain in general known to me
is by Dareste (1) ; but this article does not include a full description of
the convolutions in any type except in the Capybara, though incidental
references are made to other types in the author’s general survey of
the characters of the cerebral hemispheres in the group. Having
formed a collection of Rodents’ brains during the last year or two
from material that came to hand at the Society’s Gardens, I think
it will perhaps be worth while to again call the attention of anato-
mists and systematists to the structure of the cerebral convolutions
in this group of Mammalia. I have examined specimens of the
following species, the brains of which show, at any rate, traces of
convolutions :—
Celogenys paca.
Dasyprocta azare.
Lagostomus trichodactylus.
Capromys pilorides.
Hydrocherus capybara.

general anatomy of the Rodents in question (3, 4). Several of
these animals have been studied by previous observers; I shall
refer to them in the following descriptive part of the present paper.

1892. | CEREBRAL HEMISPHERES OF RODENTS. 597

§ 1. Description of the Cerebral Hemispheres in certain Genera.

Castor canadensis’.—Total length 54 mm., breadth 41 mm.,
height 25 mm.

The cerebral hemispheres trend away from each other posteriorly,
permitting the corpora quadrigemina to be seen; they are closely
applied anteriorly. The length of each hemisphere is 38 mm.; the
hemispheres are wider behind than in front; the width gradually
increases up to a point a little in front of the middle of the hemi-
sphere ; thence the two margins are approximately parallel to each
other.

The upper surface of the cerebral hemispheres is nearly completely
smooth ; at about the end of the first half of the hemisphere is a
short fissure shaped like the Greek letter y; behind this, separated
from it by a considerable interval and further from the middle line,
is a very short (3 mm. long) longitudinal fissure. These two
fissures are indicated by Leuret and Gratiolet as forming one
continuous fissure. On the under surface of the brain no trace was
apparent of the Sylvian fissure. The rbinal fissure is by no means
clearly marked ; it is only obvious anteriorly and again just before
the posterior margin of the hemispheres; it ends at a distance of
15 mm. from the upper surface of the hemispheres. The olfactory
bulbs are large.

Capromys pilorides.—Length 38 mm., breadth 26 mm., height
16 mm.

The cerebral hemispheres (fig. 1, p. 593) show the same rounded
oval contour that distinguishes the brains of the Porcupines. The
extreme diameter of the hemispheres is reached a very short distance
behind the anterior end of the brain. The posterior divergence of
the two hemispheres partly displays the corpora quadrigemina.
Each hemisphere measures 25 mm. in length. The surface is faintly
marked by a few furrows. A longitudinal furrow (see woodcut,
fig. 1) on each side starts from the inner angle of the hemisphere ;
it is altogether 9 millimetres long; it passes at first forwards and
outwards, and then at the middle of its length changes its direction
and runs straight forwards parallel to the long axis of the brain; a
very short branch is given off at this point which continues the
straight line of the first part of the furrow; another short branch
parallel to this is given off on the side just before the end of the
furrow. These furrows are more strongly marked on the right
half of the brain. In front of this posterior longitudinal furrow
is a short C-shaped furrow not connected with it; the concavity of
this furrow is directed inwards. There are indications of a very
faint transverse furrow at a distance of 10 mm. from the intercerebral
sulcus and about 4 mm. from the posterior margin of the brain. A
diagonal furrow about 8 mm. in length is partly visible on the
sides of the hemispheres when the brain is viewed from above; it

1 Figured by Lenret and Gratiolet (8, plate i‘i. fig. 1).

598 MR. F. E, BEDDARD ON THE [Dec. 6,

occupies the middle of the length of the hemisphere and runs from
above downwards; on the left side of the brain this furrow gives
off a faint branch which seems to be the Sylvian fissure—otherwise
hardly marked.

On the inferior surface of the brain the rhinal fissure is seen to be

perfectly continuous and quite well marked froin end to end. As
already mentioned, I found the greatest difficulty in discovering any
traces of the Sylvian fissure excepting in the lateral region of the
hemispheres, where it is present.

Myopotamus coypu.—Total length 39 mm., breadth 28 mm.,
height 14 mm.

The cerebral hemispheres are nearly but not quite smooth ; there
being indications of furrows which are more strongly marked in
other genera. The extreme length of each hemisphere is 28 mm.
They diverge posteriorly so as to display a portion of the corpora
quadrigemina—both nates and testes; the latter are, however,
partly concealed by a projection of the cerebellum. Anteriorly the
two hemispheres become very narrow and diverge in a marked way
from each other ; passing back, the hemispheres rapidly increase in

breadth until about the middle point, when the margins are nearly
parallel, converging slightly posteriorly. The rhinal fissure is quite
continuous ; the Sylvian fissure is represented by the merest trace.
On the upper surface of the brain there are two short furrows on
each side, one in front of and to the outside of the other.

Lagostomus trichodactylus—Total length 43 mm., breadth
35 mm., height 18 mm.

The cerebral hemispheres diverge posteriorly so as to display the
corpora quadrigemina ; they do not diverge at all anteriorly. The
extreme length of each hemisphere is 31 mm. ‘The hemispheres

are wider behind than in front ; the breadth increases very gradually
up to the Sylvian fissure ; at this point the brain suddenly becomes
wider.

The brain (fig. 2) is marked by several fairly deep furrows and
by other slighter ones. These are perfectly symmetrical. On
either side of the intercerebral fissure is a furrow 9 mm. long which

600 MR. F. E. BEDDARD ON THE [ Dec. 6,

commences about 5 mm. from the posterior end of the brain
and at about the same distance from the interhemispheral
fissure ; this furrow is slightly oblique in direction, the anterior
end being nearer to the middle line than the posterior. In
front of this is another furrow, rather deeper but about the
same length; this furrow is twice the distance from the median
furrow, that is the last described furrow, and shows a tendency (on
one side) to bifurcate anteriorly. If the anterior end of the pos-
terior furrow were bent away from the middle line of the brain, it
would come to be continuous with the anterior longitudinal furrow ;
as it is a space of 3 mm. separates the two. Parallel with the
posterior longitudinal furrow are two less conspicuous fissures ; they
run at about equal distances from each other and from the furrow
first described: the inner of the two is only just visible; it is very
short and very plainly marked: the outer is 10 mm. in length; it
starts from tke posterior border of the hemisphere ; but the posterior
part of this fissure is much shallower than the anterior half, and
is indeed only plainly recognizable on the right hemisphere. The
Sylvian fissure is very deep on the upper surface of the brain
though shallow at its commencement; its direction is on the whole
at right angles to the longitudinal axis of the brain; it is, how-
ever, curved, the convexity of the curve being forwards; at about
the middle of its course it gives off a short forwardly running
branch, the direction of which is also slightly downwards.

On the under surface of the brain the only distinct fissure (apart
from the Sylvian) to be seen is the rhinal fissure. This is quite
obvious from end to end. This fissure can be traced back on
the posterior aspect of the hemispheres up to within 6 or 7 mm. of
the upper surface of the brain.

Hystrix cristata‘.—Total length 45 mm., breadth 36 mm.,
height 20 mm.

The cerebral hemispheres are very broad and together have an
almost circular contour. They diverge posteriorly so as to reveal
the corpora quadrigemina. The upper surface is furrowed to some
extent, though not to so marked a degree as in some other genera.
The length of each hemisphere is 30 mm.

A longitudinal furrow about 10 mm. long runs on either side of
the median furrow on the posterior half of the hemisphere ; rather
in front of the middle of each hemisphere, this furrow is very
nearly continuous with a much deeper furrow passing obliquely
outwards at an angle of about 30° with the transverse axis; this
furrow, which is about 13 mm. long, is restricted to the dorsal
surface of the brain. The remaining furrows are decidedly asym-
metrical in their arrangement.

On the left half of the brain there are two downwardly directed
fissures running parallel with the Sylvian fissure. On the right

? Figured by Leuret and Gratiolet (8, plate iii.).

1892. ] CEREBRAL HEMISPHERES OF RODENTS. 601

hemisphere I could only recognize one of these. On the right half
of the brain there is a marked indentation to the outside of the
posterior extremity of the longitudinal furrow.

On the under surface of the brain the rhinal fissure is seen to be
very distinct and complete. The Sylvian fissure is not so distinct
where it joins the rhinal fissure as it is laterally; just in front of
the Sylvian fissure is a small fissure arising from the rbinal fissure,
which appears to be the termination of the anterior transverse
fissure of the dorsal surface of the brain.

Sphingurus prehensilis—Total length 36 mm., breadth 27 mm.,
height 19 mm.

The cerebral hemispheres show the same peculiar shape that is
seen in Aystriz; their contour is almost circular ; the posterior
divergence of the two hemispheres is so nearly filled by the projecting
cerebellum that the merest peep at the corpora quadrigemina is
alone possible.

Each hemisphere measures 24 mm. in length; the upper surface
is smooth, but not so smooth as in the Beaver; it is marked by a
good many meandering lines which are for the most part directed
downwards. I do not describe these particularly as they do not
appear to me to be of any morphological importance. In addition
to these there are two dents on the upper surface of the brain.
The posterior of these is placed at a distance of about 6 mm. from
the hinder margin of the brain; the anterior mark is about the
same distance in front.

The rhinal fissure is not well marked, but it is complete. The
Sylvian fissure was hardly apparent.

Sphingurus villosus.—Total length 36 mm., breadth 30 mm.,
height 20 mm.

This brain is almost exactly identical in size with that of the last
species; nor is there any occasion to describe the general shape
and the proportions of its various regions, for they are precisely
as in Sphingurus prehensilis.

On the other hand, the brain is deeply furrowed in comparison
with that of the other Sphingurus. It appears to me to be a very
remarkable fact there should be this difference in the brain-surface of
two animals of the same size and belonging to the same genus. The
rhinal fissure is quite deep and perfectly complete. The Sylvian
fossa is much deeper than in Sphingurus prehensilis. The Sylvian
fissure is also quite conspicuous and passes on to the dorsal side of
the brain, where it is deeper than at its origin; this region of the
Sylvian fissure is represented by the posterior of the two dents upon
the surface of the brain of Sphingurus prehensilis. In front of this
fissure are two others equidistant from it and from each other,
which run in a similar direction; besides these principal fissures
are numerous smaller ones which are principally branches of them.
There was no longitudinal fissure.

Dasyprocta azare.—Total length 46 mm., breadth 30 mm.,

The cerebral hemispheres are very closely applied along nearly
their whole lengih ; the divergence posteriorly only permits a portion
of the anterior pair of corpora quadrigemina to be seen when the
brain is viewed from above. Each hemisphere measures 30 mm. in
length and is furrowed. The general contour of the hemispheres
does not differ from that of the last animal.

The principal furrow (fig. 3) runs longitudinally at a distance

of about 5 mm. from the interhemispheral sulcus. It com-
mences close to the posterior margin of the brain and passes
nearly as far as the anterior end; at the end of the first third of
the total length of the hemisphere this furrow gives off a branch
which runs forwards and outwards, joining the rhinal furrow below ;
8 mm. behind this point (on the left half of the brain), or 11 mm.

(on the right half), the Sylvian fissure also joins this longitudinally
running furrow.

A. second longitudinal furrow, at about the same distance from the
first described longitudinal furrow as the latter is from the median
interhemispheral furrow, and commencing about 5 mm. from the
posterior margin of the brain, has a course of 4 or 5 mm.; this
furrow is rather more strongly marked on the right half of the brain.
Again, to the outside of this is a longer furrow but less strongly
marked, which commences at the very margin of the brain just
opposite to the point where the rhinal furrow is lost beneath the
corpora quadrigemina; this furrow is situated about twice as far
from the second longitudinal furrow as that furrow is from the first.
Its length is about 12 mm.

On the under surface of the brain the hippocampal gyrus is seen
to be very prominent in the temporal region, and when the brain is
viewed laterally this convex projection is very apparent. The rhinal
fissure is complete and anteriorly appears to give off a short
forwardly running branch such as I have described in Ccelogenys.
The Sylvian fissure is very slightly marked where it joins the rhinal
fissure.

The olfactory bulbs are large.

Leuret and Gratiolet’s figure (8, pl. iii.), though in my opinion
better than that of Owen, is not so clear as the drawing which I
exhibit.

Celogenys paca.—Total length 53 mm., breadth 42 mm., height
23 mm.

The cerebral hemispheres diverge posteriorly so as to display
the corpora quadrigemina ; there is no divergence anteriorly. Hach
hemisphere measures 34 mm. in length and is considerably wider
behind than in front, the diameter increases more rapidly after the
Sylvian fissure.

The surface of the hemispheres (fig. 4, p. 604) is indented by
a few very deep furrows, which are quite symmetrically arranged.
A furrow 10 mm. long lies posteriorly at a distance of 7 mm. from
the interhemispheral sulcus ; anteriorly there is a shorter furrow
which suddenly bends outwards posteriorly and runs almost parallel
with the margin of the hemisphere. The posterior furrow is con-
tinued forward by a very faintly marked furrow which approaches
the middle line and then turns outwards, joining or running just
behind the end of the anterior furrow. On the right side of the
body there is a small but deep indentation on the inner side of the
posterior furrow, between it and the interhemispheral furrow ; there
is also (on both sides of the brain) another dint—it is hardly long
enough to be called a furrow—on a level with the hind extremity
of the posterior furrow and about as far from it as that furrow is
from the median interhemispheral sulcus.

Outside this again is a shallow furrow which begins at the
posterior margin of the hemisphere, just on a level with the end of

604 MR. F. E. BEDDARD ON THE [Dec. 6,

the rhinal furrow (on the right side); its course is longitudinal, but
at an angle of about 30° with the longitudinal axis.

On the under surface the rhinal fissure is complete and very deep
and wide ; on the hinder aspect of the brain it is seen to reach to
within about 12 mm. of the inner corner of the hemisphere ;

anteriorly the under surface of the pallium is marked by a short but
deepish fissure which appears to become continuous with the rhinal
fissure, but is really, in all probability, a distinct longitudinal groove
upon the lower surface of the pallium. The hippocampal lohe is
marked by an indentation just on a level with the Sylvian fissure ;
there are also faint transverse lines in front of this. The Sylvian
fissure is represented by a mere notch, more emphasized on the right
half of the brain than on the left.
The olfactory bulbs are large.

1892. ] CEREBRAL HEMISPHERES OF RODENTS. 605

The brain of this animal is also figured by Leuret and Gratiolet
(8, pl. iii.). The furrows are not, however, sufficiently marked
in their drawing.

Cavia porcellus.—Length 28 mm., breadth 20 mm., height
12 mm.

The description of this brain need not occupy us long, since the
convolutions upon the cerebral hemispheres are very greatly reduced
as compared with allied forms. The outline of each hemisphere,
which measures 20 mm. in extreme length, is roughly triangular ;
the widest point is not far in front of the posterior margin of the
hemispheres ; thence the opposite margins converge to the anterior
end of the brain, which is of slight diameter. The hemispheres are
divaricated behind so as to display the corpora quadrigemina.

On the under surface the rhinal fissure is well marked, entirely
separating the rhinencephalon from the pallium ; this fissure is
considerably deeper behind than in front. In the temporal region
the rhinencephalon is very convex, a more or less strongly marked
fissure (the Sylvian fossa) separating the convex posterior from the
more flattened anterior part of the rhinencephalon. The rhinence-
phalon is visible when the brain is viewed laterally. On the left
side there is a distinct Sylvian fissure, which extends for a distance
of about 6 mm.; its direction is almost vertical, but it slopes back-
wards alittle. On the right side of the brain there was no trace
that I could see of this fissure.

The upper surface of the brain is but little fissured. On each
hemisphere is a short fissure about 5 mm. long commencing a little
way in front of the posterior margin of the brain and situated 3 mm.
from the median interhemispheral fissure; in addition to this
another longitudinal fissure is present on each side 5 mm. away
from the last, longer and commencing at the posterior margin.
This fissure is, however, even shallower than the last, but in spite
of this is perfectly evident.

It is generally stated that the convolutions of the hemispheres
bear some relation to the size of the animal; thus in relation to
the Cervide Sir W. H. Flower has pointed out’ ‘ how closely the
amount of convolution bears relation to the bulk of the hemisphere,
the primitive pattern being exactly the same in all.” Again, among
the Primates the Marmoset has the tiniest brain, and this brain is
guite smooth. Broadly speaking the rodents form no exception to
this generalization; its truth becomes more apparent when the
comparisons of extent of complication of brain-surface are restricted
to a family rather than when applied to the whole group.

Otherwise the brain of the Beaver forms a marked exception ; it
is as large as any rodent brain excepting Hydrocherus and is nearly
perfectly smooth, while considerably smaller brains, such as Lago-
_-stomus, are decidedly convoluted.

The above-given account of the various brains which I have been

14, p. 174.
Proc. Zoou. Soc.—1892, No. XLI. 4]

606 MR. F. E. BEDDARD ON THE [ Dec. 6,

able to examine leads me to disagree with some of the statements in
Dareste’s paper (1). After describing the convolutions of the
Capybara he remarks :—“ II n’existe point dans les autres Rongeurs
de véritables cireonvolutions ; mais les anfractuosités et les depres-
sions que l’on observe 4 la surface du cerveau de leurs grandes espéces
sont manifestement, dans leur disposition, )ébauche et comme
Vindication des circonvolutions si développées et si nettement des-
sinées du Cabiai.” Sir William Turner also, in his interesting
survey of the Mammalian brain (2), says upon the same subject :—
“‘The Rodentia are almost universally smooth-brained. But in
some genera traces of shallow fissures may occasionally be seen on
the surface which indicate an early stage in the formation of
convolutions.” It appears to me that both these statements under-
estimate the actual development of fissures and convolutions * upon
the brain of the larger Rodents. I do not, I confess, see any reason
for M. Dareste’s distinction between the “ circonvolutions” of the
brain of Hydrocherus and the “anfractuosités” of the brains of
some other forms; perhaps, however, Dareste had not in his hands
such well-preserved brains as I-have been able, thanks to the skill
of my assistant Mr. Ockenden, to examine. Judging from a
specimen of the brain of Hydrochwrus which I have seen by the
kindness of Mr. Charles Stewart in the Museum of the Royal
College of Surgeons, the fissures in this rodent are not more marked
than they are in, for example, Lagostomus ; but the latter is one of
the best developed brains in this respect, and it is one of the types
which M. Dareste did not examine or refer to; I should, however,
dispute his statement even when applied to the Agouti; I think
that a comparison of my figure of the brain of this rodent with
M. Dareste’s figures of the brain of Hydrocherus will bear out my
remarks.

Another point in which I find myself in disagreement with
M. Dareste concerns the Sylvian fissure. He remarks, and judging
from his figure with perfect truth, that the Capybara has no fissure
in its brain which can be compared to this universally present
fissure ; it is, however, a little rash to found upon the examination of
a single type (he says nothing in this matter of the other Rodents’
brains) a generalization of so much importance as that which
Dareste proceeds to formulate, viz.:—‘‘ Le cerveau des Rongeurs
nous présente, selon toute apparence, un type distinct de celui des
Primates, des Carnivores et des Ruminants; type principalement
caracterisée par l’absence de la scissure de Sylvius, et par suite par
Vabsence de la division du cerveau des deux lobes, un antérieur,
Yautre postérieur 4 la scissure.’ Sir W. Turner also remarks
that ‘‘ The Sylvian fissure . . . is not seen . . . in the lissencephalous
Rodents.” The Sylvian fissure is undoubtedly feebly developed in
the majority of those Rodents * the brains of which I have personally

1 Leuret and Gratiolet head plate iii., on which Rodents’ brains are figured,
with the title “Encéphale des Mammiféres dont les lobes cérébraux sont
dépourvus de circonyolutions.”

* The Sylvian fissure also exists in a few perfectly smooth-brained Rodents
for instance in the following :—Sciurus, Dipus, Gerbillus, Chinchilla.

1892. | CEREBRAL HEMISPHERES OF RODENTS. 607

studied; but it is quite impossible to characterize the group by
the absence of this fissure; for instance, there is a distinct trace
of this fissure in Celogenys and in Capromys; Dasyprocta has quite
a respectable Sylvian fissure, though, as I have already pointed out,
it is not thoroughly certain which of the two fissures to be
found in this neighbourhood is to be compared with the Sylvian
fissure of other Mammals; but the best exception to M. Dareste’s
unfortunate generalization is shown by the genus Lagostomus,
where the Sylvian fissure is so deep and extensive that it could
not possibly be overlooked, and moreover appears on the dorsal
aspect of the brain, as shown in the drawing which I have already
exhibited (fig. 2, p. 599). I do not think it worth while to follow
M. Dareste into his comparison of the Rodent brain with that of
the Marsupials and more particularly of the Kangaroo; he chiefly
bases this comparison upon the supposed absence of the Sylvian
fissure in the latter animal, a supposition which is not true (see for
example the woodcut (fig. ii.) illustrating Sir William Turner’s
paper upon the mammalian brain).

§ 2. Comparison of the Brains of the Genera described inter se.

The convolutions of the Rodent’s brain can be satisfactorily
compared; but unfortunately most genera have small brains which
either show no traces of any furrows or only traces. The furrows
are, however, well developed in Celogenys, Dasyprocta, Dolichotis,
Lagostomus, and Hystriz; traces of the more important furrows
can be recognized in Castor, Aulacodus, Capromys, Sphingurus,
Myopotamus, Lepus, Cavia, and Octodon; the brains of Sciurus,
Dipus, Gerbillus, and Cricetus are quite smooth.

The brain of Dasyprocta is a convenient starting-point; I shall
therefore briefly recur to the furrows which mark the cerebral
hemispheres of this Rodent. I do not propose to call these furrows
by any names, for that would imply a direct comparison with the
similarly named furrows in the brains of other Mammalia; I doubt
very much how far such comparisons can be safely made. Each
hemisphere has five furrows (apart from the ‘“rhinal” furrow,
which I leave aside for the present), three of which run parallel with
the long axis of the brain and two somewhat transversely to that axis.

The most important of these furrows (a, see figs. 2, 3, & 4,
pp- 599, 602, 604) runs at a distance of about 5 mm. from
the interhemispheral suleus nearly from end to end of the
brain. The second longitudinal furrow (4) is very short, about 5
mm. long, and about 5 mm. distance from a. The third longi-
tudinal furrow (c) is about twice the length of the last, and is
situated about midway between the dorsal and ventral surfaces of
the brain when the brain is seen in profile. At the end of the first
third of the hemisphere the furrow @ gives off a transverse furrow
(d), which joins the rhinal fissure ; behind this, at the end of the
second third, is a second transverse fissure which as @ on one

side only, and separates the temporal from the frontal lobe; I
have no hesitation in terming this the Sylvian fissure.

In the brain of Lagostomus (fig. 2, p. 599) the same fissures are
present, but differently developed; @ is broken into two separate
fissures on each side, 6 has almost disappeared, c is also rudimentary ;
between 6 aud cis a short fissure 6’ which seems to be unrepresented
in Dasyprocta ; of the transverse furrows d is only just indicated
at its junction with a, while the Sylvian fissure is very deep and
does not nearly reach a.

In Dolichotis (fig. 5) a is even longer and stronger than in

point where d would join it were that furrow present ; the Sylvian
fissure is deep and bifurcate at the upper end, nearly joining a.

Celogenys (fig. 4, p. 604) has aless convoluted brain. The fissure a
is divided into two quite separate portions, which occupy the first
and last thirds of the hemisphere; 4 is merely a deep dent which is
rather transverse in direction, running towards e: neither d nor the
Sylvian fissure was well developed ; on one side, however, the latter
could be made out, and there were indications of d as a deepish
depression connected by a shallow furrow with the end of the first
part of a.

In Hystrix a is not extensive; fissures which possibly correspond
to 6 and ¢ are present but run obliquely outwards; ¢ and d are well
developed, so that altogether the furrows have a markedly oblique
disposition.

In the smaller brains a is, as in the larger brains, the most
important fissure upon the upper side of the brain. It is the only
one present in Octodon and Myopotamus.

§ 3. The Structure of the Hemispheres and the Classification
of the Rodentia.

It is not my object here to enter into any detailed account of the
various ways in which this group of Mammals has been arranged
by various authorities; I shall only point out how far the results
which I have been able to get together affect the scheme of classifi-
cation propounded by the late Mr. Alston. This naturalist divided,
it will be recollected, the Order Rodentia into three groups:—
(1) Hepepentati ; (2) Simpyicrpentati1; (3) DupticipENTaTI.
We are here only concerned with the last of the three groups, which
are separated by Alston into a number of families.

The following are the families of which I have personally exam-
ined brains, with the genera which I have examined :—

Sciurus.
Castor.

(2) MyomorpuHa.

It will be noticed at once that the convoluted brains belong to the
last of the three divisions of the Simplicidentati; the obscure dints
upon the upper surface of the cerebrum of the Beaver are apparently
the only apology for convolutions possessed by either the Sciuro-
morpha or the Myomorpha. In point of size there is every reason
why some of the members of these two groups should have
recognizable convolutions ; apart from the Beaver, which is one of
the largest of the Rodentia, there is the Common Squirrel, whose
brain is distinctly bigger than that of Octodon, in which genus there
are decided traces of convolutions ; it seems to me therefore that—
for the present at least—we may regard these two groups of the
Simplicidentati as being characterized by the entire absence of
convolutions. It is quite otherwise with the Hystricomorpha; the
larger members of this group show convolutions which can be
reduced to a common plan. But there are differences among the
genera which permit of an arrangement in accordance with the
varying condition of the convolutions. The Hystricide form a
perfectly natural family. Their brain is characterized by its peculiar
shape, rounded in front, and by the fact that the convolutions for
the most part are transverse and not longitudinal in direction. Only
in Hystrix itself is the principal longitudinal furrow a, which occurs
in all other Rodents whose brains show any convolutions at all,
represented to any extent. In relation to this fact it may be
pointed out that we may fairly regard Hystrix as the least special-
ized of the Rodents whose brains are treated of here. The only
animal whose brain approaches that of the Porcupines is, as I have
already pointed out, Capromys ; the brain of this Rodent is rounded
off in the same way anteriorly. The convolutions are so feebly
developed that the comparison can perhaps hardly be pushed any
further. It may, however, be worth remarking that a lateral furrow,
which I regard as being a part of the Sylvian fissure, is well marked
both in Capromys and in the Porcupine. This latter furrow is also not
inconspicuous in Aulacodus (fig. 6, p. 611), the relationships of which
to Capromys are apparent from a comparison of their brains. Even in
Myopotamus, where the shape of the brain is very different from that of
other Octodontide, thereis a distinct trace of the lateral oblique furrow
which is so well marked in both Aulacodus and Capromys. In any
case, therefore, the naturalism of the family Octodontide is shown by
a comparison of their brains, We next come to the Dasyproctide,
represented by the two genera Dasyprocta and Calogenys. Of these
two brains Celogenys is the larger, and yet it has the fewest furrows ;

1892.] CEREBRAL HEMISPHERES OF RODENTS, 611

these furrows are, however, deeper than in Dasyprocta. The chief
point of agreement between them, and that which causes them to differ
from the two remaining families, is the absence of the Sylvian fissure;
this brings Hydrocherus into relation rather with the Dasyproctidee
than the Caviidee, where it is placed by Alston. Judging also from
Dareste’s figure, the general outline of the brain of Hydrocherus is
like that of Calogenys, but also of Lagostomus. In all these three
genera the principal longitudinal fissure, which I have called “a,”
is divided into two portions, one anterior and one posterior. Apart

from this the brain of Zagostomus appears to be nearer to that of
Dolichotis. They have both of them a deep Sylvian fissure, and the
furrows 4 and ¢ tend to converge towards the middle line; finally,
the rhinal fissure in both genera is deeper behind than in front. I
have not ventured to treat at length of the evidences of affinity
afforded by the convolutions, since the illustrations are before the
reader, who can form his own opinions.

a domesticated Rabbit, and was dissected in the laboratory of the
Royal College of Science by one of Prof. Howes’s students. Ordi-
narily the brain of this Rodent has but one slightly marked furrow
upon the upper surface of each hemisphere, which corresponds to
that lettered @ in the series of woodcuts which illustrate this paper.
In the brain before me this furrow is present, but it is continuous
from one end of the brain to the other, having a somewhat zigzag
course ; at the angles formed by the zigzags of furrow a a number
of transverse furrows are given off, which for the most part reach
the under surface of the cerebrum joining the rhinal fissure. In
addition to these (of which one seems to correspond to the Sylvian

fissure) there are numerous connecting furrows; the whole surface
of the brain is indeed divided up by a network of furrows with a
development far in excess of anything met with in any other
Rodent known tome. The very number and variety in direction
and extent of these furrows make it quite easy to select some which
can be identified with those upon the cerebral hemispheres of other
Rodents. It is of course difficult, if not impossible, to come to any
definite opinion as to the significance of the furrows upon this
particular brain ; if they are an accidental expression of the possi-
bilities of modification in the brain-surface, it is noteworthy that
the Rabbit departs very widely from the Simplicidentati. In the
latter group the tendency upon the whole appears to be a stronger
development of longitudinal furrows, thus resembling the Ungulata.

2. On a new Monkey from North-east Sumatra.
By R. Cotterr, C.M.Z.8.

[Received November 8, 1892.]
(Plate XLII.)

During the years 1888 and 1889, Herr Iversen, one of the pre-
parators of the University Zoological Museum of Christiania, resided
on the north-east side of Sumatra in order to collect specimens for
the museum.

Through the kindness of two young Norwegians, the Messrs,
Kamstrup, who are established there, one in the district of Langkat,
the other in that of Deli, Herr Iversen, by living in turns on their
estates, has been enabled to make a very important collection of the
vertebrated animals of those districts. As the collection of Ver-
tebrates is not yet completed, but is being steadily increased by
Messrs. Kamstrup themselves, I intend, at a later opportunity, to
give a general account of the whole of the materials furnished from
these parts. On the present occasion, however, I wish to give a short
diagnosis of a Semnopithecus which does not appear to have been
previously described, and to which I have great pleasure in attaching
my friend Mr. Oldfield Thomas’s name.

SEMNOPITHECUS THOMASI, sp. n. (Plate XLII.)

Diagnosis.—A central occipital crest sloping at first backwards,
but reversed on the occiput; a lower (indistinct) crest on each side
of the forehead. Colour above dark grev, white underneath; hands
and feet black. The cheeks, front, and forehead are white; a black
stripe from the upper jaw to the ear, and a black central stripe on
the forehead ; the very old male darker, with the upper part of the
head brownish black, front whitish.

Locality.—Langkat, N.E. Sumatra (7 specimens procured ; Uni-
versity Museum, Christiania).

In form and general appearance this Monkey resembles the group

614 PROF. R. COLLETT ON A [ Dec. 6,

to which 8. femoralis and S. obscurus belong, and appears to be
closely related to S. hosei from North-west Borneo’, described in
1889 by Mr. Thomas. The distribution of the colouring is in several
respects identical with that of the latter, but there is a characteristic
difference in the colouring of the cheeks, which do not, as in S. hosei,
form a connected white area with the white forehead, but the area
is broken by a black band from the edge of the mouth to the ear
(in the young male and the female); in the old male the upper
parts of the cheeks are nearly entirely black. The crest likewise
does not slope evenly backwards as in S. hosei, but is reversed on
the back of the head and runs upwards towards the centre of the
crown.

From S. femoralis, to which especially the old male seems to be
nearly related, it is distinguished by the white forehead and the
wholly white under surface, both of head, body, and tail.

Size.—The fully developed male is about 620 miilim. in length (head
and body); the length of the tail is about 810 millim.

The fully developed female is somewhat smaller. The length of
the body (head included) is about 600 millim. The length of the
tail varies, but is about 650 millim. ; in one specimen it was only
590 millim., whilst in another specimen of equal size it was 710
millim. :

The hair-covering of the head.—The greatest height of the longi-
tudinal crest on the crown is about 75 millim. in the old male, while
in the female it is shorter, or from 42 to 58 millim. It juts out
from the centre of the forehead at a short distance from the eye-
brows. On the front of the head the crest slopes backwards ; but
on the back of the head it is directed forwards, there being a hair
spiral behind each ear. The hairs on the crown thus converge and
form a high point on the occiput. On the neck the hairs of the
crest again slope backwards. On the sides of the forehead the hairs
have likewise (especially in the females) a disposition to form a low
crest which runs parallel to the central crest; the hairs here run
together to a projecting point, where they meet the spiral behind the
ear. There is scarcely any trace of a chin-tuft, as seen in S. hosez
and other species.

Colouring.—The upper part of the body is of exactly the same
shade as in S. hosei, being a uniform grey colour owing to each hair
being black and white in turn (without, however, having the rings
sharply defined). On the sides of the body and the hinder parts of
the thighs the grey colouring shows a tendency to form a darker line
in the transition to the white, especially in the older specimens.

The crest on the crown is black; the occiput is partly whitish.
The forehead is white, and divided in the middle by a black stripe,
which joins the crest. The side crest, which extends from behind
the side of the eye to the ear, is black and encloses in front (behind
the eye) a whitish space. The lower part of the cheeks and the
underside of the head arealso white, but a black stripe which stretches
backwards to a pointed whisker always runs from the upper jaw

1 Proce, Zool. Soc. 1889, p. 159, pl. xvi.

1892.] NEW MONKEY FROM SUMATRA. 615

down to the underside of the ear. The undersides of the head
(lips included) and the whole of the underside of the body are white
or whitish. The limbs are coloured on their outer sides as on the
back; the hands and feet are black. The inner sides of the limbs
are white like the belly. The upperside of the tail is grey, like the
back, the underside white; only the extreme point is greyish brown
both above and below.

The iris is brown.

The old male is slightly darker than the younger male and the
females; the top of the head, and the sides from the eyebrows down
to about the angle of the mouth, are black or blackish. The forehead
is whitish. The limbs are also darker downwards ; the lower part
of the hind Jimb is mostly black.

The young one, in silky dress, is whitish. The head is almost
entirely white, and likewise the hind limbs; the hands and feet are
whitish; the back, shoulders, and uppersides of the fore limbs, as
well as the upperside of the tail, are greyish (almost like the old
ones) ; in the centre of the back there is a whitish patch.

The crest on the crown already forms a distinct point on the
occiput, whilst the side crests and whiskers are barely discernible.
Along the neck runs a black central stripe.

The distal portion of the tail is somewhat more hairy than the
proximal.

Soramen incisivum.

Intertemporal constriction strong ; it equals the distance from the
foramen magnum to the centre or hinder edge of m.

The nasals are slender and straight, or even somewhat concave ;
above them the interorbital space is sunk inwards.

The bulle are low, almost flattened in the female, but rather
more elevated in the old male,

The canines in the male are particularly long.

The lower jaw is almost uniformly high throughout its length
from p-* to m.°,

The occipital is strongly rounded behind, and does not show a
trace of any transverse crest.

The orbits are wide, with a distinct angle above on the outer side ;
their height is less than their breadth.

In the young one the peculiarities of the skull are still but little
prominent. The dulle are proportionally more swollen than in the
old ones.

Hatits.—These Monkeys were only met with by Herr Iversen in
the Langkat district, and were not observed in Deli. They were
fairly numerous on several of the estates, especially at Glen Bervie
and Bekri. Their haunts were in the highest trees, and they never
descended of their own accord to the ground or visited the rice-
fields. Herr Iversen saw, however, one wounded individual take to
flight on the ground. They always live in companies, and inhabit
the dry spots in the thickest parts of the forests. They appear
to be non-migratory, and may be met with at all times of the year
in almost the same parts of the forest. ‘They hardly ever visited the
more open places, but kept to the highest tree-tops, where they
moved about with the greatest ease, and made the most astonishing
leaps through the branches. They were on the whole excessively
shy; if they found themselves noticed, they endeavoured at once to
hide themselves, and the mothers would leave their young sitting
on the branches whilst they themselves sought shelter in the tree-
tops. When hunted, they all took to flight in the same direction,
so that the companies were not dispersed.

The companies appeared to consist chiefly of full-grown indivi-
duals, and young ones were but seldom seen. An occasional half-
grown individual, however, might be noticed following the old ones ;
babies were not often seen, but these are, on the whole, more difficult
to observe, as they are carried by the mother under her belly.

The young one brought home was noticed through the mother
deserting it, after which it began to shriek. They have a very
penetrating cry, which they generally utter in chorus after one has
given the note. In the individuals which have been examined no
foetus has ever been found. Possibly the pregnant females and the
younger ones hide themselves more closely.

They were seen in activity only in the daytime, and were not heard
to cry at night. They lived, it appeared, only on fruits. In their
stomachs was chiefly found the soft pulp of a fruit belonging

Specimens from Perak, as well as others from Pulo Laut, Borneo,
have a bluish tinge, which is not evident in Javan examples, and
both sexes are much darker on the wings than specimens from
Nias, which may be a local race, though they agree on the underside.

I cannot see how to distinguish M. zinckeni, Feld., from Java.

Several specimens from Perak agree with others from Sumatra,
Nias, and Pulo Laut, one of which is marked biggsii 2 by Doherty.
I have little doubt that these are the same species as de Nicéville
described from Perak, which he distinguishes from diggsii (of which
he had not seen the type) by the distinctness of the markings below.
Neither Distant’s figure nor his description is clear enough to identify
his species, which came from Malacca; and there is some variation
in the markings of both the upper and underside among my
specimens.

GERYDUS HERACLEON.

Gerydus heracleon, Doh. J. A. 8. B. Ix. pt. ii.no. 1, p. 36 (1891).

The type of this species, from Perak, is like the last but larger,
and with the markings below more like those of G. symethus.

It does not appear to me to be sufficiently distinct to be de-
scribed from a single specimen, and the band is not appreciably
broader than in G. biggsii (gopara), as Doherty says it is. Judging
from the figure, it is also very close to Miletus melanion, Feld.,
from Luzon.

GERYDUS CROTON.

Gerydus craton, Doh. J. A.S. B. lviii. pt. ii. p. 439, t. xxiii. 9 ;
Butt. Ind. iii. p. 25.

Four males and two females from Thandaung in East Pegu at
4000 feet elevation. The type was from the Tenasserim valley.
The plate does not agree with the underside of my specimens
(named by Doherty), which are of a more rusty colour and have
broken markings on the hind wing. It seems, however, a very
distinct species.

GERYDUS IRRORATUS, Druce, var. ASSAMENSIS.

Gerydus irroratus, var. assamensis, Doh. J. A.S. B. 1x. pt. ii.

The type of this is from the Dhansiri valley in Assam, and a
female from Perak is marked by Doherty with a’. -

This species seems identical with one of which I have several
pairs from Pulo Laut, and differs from all the preceding in having
a pale sexual patch in the cell of the fore wing of the male as in
Paragerydus horsfieldi.

GERYDUS BOISDUVALI.

Miletus boisduvali, Moore, Cat. E. I. C. p. 19, t. la. fig. 1 Q
(1857).

Gerydus boisduvali, Butt. Ind. iii. p. 24.

Specimens from Margharita agree with those from Sikkim and
from the Shan Hills.

I have one pair from Sikkim which differ considerably in the
colour and pattern of the underside, having a dark transverse band
on the hind wing below, and also in having the tuft of bristles at
the base of the anal claspers in the male black instead of grey.

If these differences should prove to be constant, it seems to me
that it could be separated specifically; but the group is a very
difficult one and the anatomy requires more study than I am now
able to give it.

others from Sumatra and Pulo Laut. I have another form from
Perak which is smaller and differs in the colour of the underside,

1892.] THE NAGA AND KAREN HILLS AND PERAK. 619

agreeing in this respect with three from Pulo Laut ; but there are
also three other forms from Pulo Laut, and one from Nias (apocha,
Kheil), which differ again in their markings below, and make me
think that the species is either a very variable one, or that there are
several species not yet distinguished, and which can only be identified
with certainty by a study of their anal organs.

PARAGERYDUS TARAS.

Paragerydus taras, Doh. J. A.S. B. lviii. pt. ii. p. 437, t. xxiii.
10; Butt. Ind. iii. p. 27.

Two specimens from the Karen Hills, so named by Doherty, are
much damaged and have lost their abdomens, but agree on the
underside with the figure. The species is well described and figured
by Doherty, who says that its prehensores are obviously different
from those of P. horsfieldi.

He also thinks that the genus Paragerydus of Distant is not
distinct from Allotinus, Felder.

ALLOTINUS MULTISTRIGATUS.

(1865).

I have no Burmese specimens of this, but two females from Pulo
Laut, which agree with Felder’s plate of A. subviolaceus from Java,
also agree with Distant’s figure, and make me think that the character
mentioned by him, viz. the larger violaceous area of the fore wing,
is inconstant.

Allotinus panormis, Doh. MSS.

A single female of this distinct species was so labelled, but 1 can
find no description published by Doherty. It came from Petichaung
at the foot of the Karen Hills. He also sent a female from Perak
which appears to be the same species, though the markings of the
underside are not quite identical.

The type, from Margharita, is the only specimen of this species
and is in my collection. As it is not in fresh condition I cannot see
whether the non-undulated appearance of the margin by which
Doherty separates it from L. marmorata is a good character, but the
Perak specimens, which he speaks of as nearest to it, agree both
with Moore’s and de Nicéville’s plates of L. marmorata ; and I have a
specimen from Moné in the Shan States, taken by Dr. Manders,
which is also very near to if not identical with L. marmorata and
shows that the species extends to the mainland north of Mergui. I
have other specimens from Pulo Laut and Nias (Miletus lahomius,
Kheil) which are closely allied, but a larger series is necessary to
decide their specific distinctness.

Logania malayica, Dist., from the Malay Peninsula, of which I
have several specimens from Pulo Laut, is easily distinguished by
the shape of the wings, and is, moreover, much paler.

Karen Hills agree well with the figures referred to. Hewitson’s plate
of the female is, as de Nicéville remarks, quite different.

With the above came two other females which are quite different
in colour above, having large orange patches, and agree nearly with
Hewitson’s plate of P. phraatica. They are, however, not the same
as what I take to be the male of P. phraatica from Tavoy, as figured
by Distant, and may be one of those cases of female dimorphism of
which we have very similar instances among the J apanese Theclas,
where orange and blue females occur at. the same time and place.

It may be, however, that these belong to a different male which
Doherty did not take.

Three males and a female of this from the Naga Hills at 5500 feet

It is perfectly distinct from Lyccena fischeri by the much darker
colour and more distinct spots of the underside, and even more so
from the form or species which occurs in China, and which has
been referred to L. fischeri by Leech, P. Z. 8. 1887, p. 455.

Of this latter I have three males and two females from Ningpo,
and one male from Kiukiang; one of the females bears a label in
the late Mr. Pryer’s writing, “ L. filicaudis, Ningpo,”’ but this name
is, I think, a MS. one only. All of these agree in having two ad-
ditional spots on the fore wing below near the base, which I do not
find in any of my 13 specimens of LZ. fischeri, which come from
Orenburg, Amurland, Askold, the Alatau mountains, Corea, and
Shanghai; but I have one male from Staudinger, marked West
Siberia, which has them ; therefore I do not know at present whether
to treat L. filicaudis as a local race of L. fischeri or not.

or markings between the sexes. I cannot distinguish the species
from Lycena potanini, Alph. Mém. sur les Lép. v. p. 104, t. v.

taken in the province of Szechuen by Pratt. It is doubtful which
name has priority, but I think that the fifth volume of the ‘ Mémoires ’

Cath id. Rhop. Mal. p. 455, t. xlii. fig. 12 ¢; Butt. Ind. iii.
p-. 146.

A pair of this species from Perak: the female differs from the
male exactly as do the females of N. macrophthalma and N. atrata,
which last it closely resembles, from their respective males. I also
have two specimens from the Karen Hills, which have the centre of
both wings above pale bluish white, and the underside pale with the
markings very indistinct, except the black marginal spots and anal
ocellus ; these agree exactly with NV. kerriana and appear to me to be
probably a dry-season form of it.

Males only from the Naga Hills, agreeing exactly with those from
Sikkim. Although the female remains unknown to me, I have no
doubt it is a perfectly distinct species.

1 Mr, de Nicéville informs me that this is the same as WV, hermes, Feld., of
which he has seen the type.

626 MR. H. J. ELWES ON BUTTERFLIES FROM [Dec. 6,

NACADUBA ABERRANS, h. sp. (Plate XLIV. fig. 6, 3.)

A single male specimen was sent from East Pegu, with the
following note by Mr. Doherty: ‘ Nacaduba sp., in appearance a
Catochrysops. Petichaung low country.”

It may be described as follows :—

Size, shape, and colour above of a small specimen of UN. atrata,
Horsf. Below paler, the two inner bands of the fore wing short,
the outer bands more lunulate, the anal ocellus nearly as large as
the one above it and showing plainly on the upper surface ; tails as
in atrata. It is unlike any other species known to me or mentioned
in the ‘ Butterflies of India.’ I have also four males, all taken by
Doherty in Car-Nicobar Island some years ago, which agree with the
type exactly, though the blue of the upperside is somewhat faded.

Specimens from Perak agree with those from the Andamans
which pass under this name, and are hardly separable, as far as I
can see, from L. elpis, though usually much smaller and having the
black border of the fore wing in the male very narrow.

LAMPIDES CORUSCANS.

Lampides coruscans, Moore, Ann, N. H. (4) xx. p. 341 (1877);
Butt. Ind. iii. p. 163.

Specimens from Perak, 7 males and 3 females, are constant in their
deep blue colour, and seem to be quite easy to separate from all
forms of L. elpis, though the markings of the underside agree.

(1886).

In adopting the name of celeno for this species I follow Mr.
Salvin, who has pointed out to me that Cramer’s plate exactly agrees
with what is usually known as P. alevis and H. elianus; for though
Cramer says it comes from Surinam, his plate is unmistakable. For
the synonymy I am indebted to Mr. de Nicéville.

It is the type of a group in which the Ist and 2nd bars of the
fore wing below reach the costa though broken at the top, whilst
the 3rd band extends to the hind margin and the 4th to the 2nd
median nervule. A specimen of the wet-season form was sent from
Perak, and some of the dry-season form from the Karen Hills.

Lampides pura, Moore, Journ. Linn. Soc. Lond., Zool. xxi. 41

This species, which I distinguish from the last by the very
narrow, usually obsolete black border-of the fore wing in the male,
occurs in Perak, and Doherty took both the wet- and dry-season
forms in the Karen Hills.

? Lampides subdita, Moore, |. c.; Butt. Ind. ili. p. 166.

This species I distinguish by the deep blue colour of the wings
above, and dark grey ground of the underside, in which it agrees
with LZ. optimus, Kheil, from Nias. The latter, however, is quite
distinct by the pale colour of both sexes above, and double border
of the fore wings in the female. Specimens from Perak agree with
some from Sumatra which, I think, are Z. saturata of Snellen.

Iycenide. The localities of these do not seem in all cases to be
quite certain, but I find two males and two females of a species
which seems like a var. of A. camdeo, though the females are of a much
darker blue than Khasia specimens, and both sexes have the spots
below nearly of the grey ground-colour of the wing, and not black
or almost black as in A. camdeo. One is marked “ Tenasserim,

I cannot separate the type of Flos ahamus, which Doherty sent
me from Margharita, from Bornean specimens of what I believe to
be the species figured by Cramer, which he says, by mistake, was
from Surinam. Doherty sent two similar females from the Naga

The type from Mergui agrees precisely with one given me by
Col. Swinhoe as A. viridissima from Mandalay, except that there is
rather more gold in the green of the centre of the fore wing.

They differ from A. ewmolphus in having the black border of the
costa very narrow, of the outer margin very narrow at the apex, so
that the green almost reaches the apex ina point, and the border of
the hind wings also narrower. Below it is paler than most speci-
mens of A. eumolphus. I do not know whether the female of this
species can be distinguished from A. eumolphus.

aequired by Mr. Rothschild, it may be possible to make sure of

identifications which have hitherto been in such genera as this very
doubtful.

the underside, but there seems to be considerable variation in the
breadth of the border, and I expect to find that this species has an
older name. In the Hewitson collection it stands as A. inornata,
Feld., but the figure of that species is not good enough to make out
what it is.

I agree with de Nicéville in thinking that only two species of this
genus can be defined in India.

The form of C. bulis sent from the Naga Hills has a white female
and resembles the commonest Sikkim form in both sexes. In the
Karen Hills the males usually have more black on the hind wing,
and the females are like them in colour, but paler. From Perak I
received a pair of smaller specimens of which the female is as deep-
coloured as the male, but with more black on both wings.

- notwithstanding Doherty’s remarks, ef. J. A. S. B. lviii. pt. ii. p- 130,
that both specimens are females, and their coloration alone would
make it almost certain.

It is curious that no species of this genus has yet been taken in
the hills of Burmah, as its distribution would certainly lead one to
expect it to occur there.

ILERDA EPICLES.

Polyommatus epicles, Godart, Enc. Méth. ix. p. 646 (1823).

I. epicles, Butt. Ind. iii. p. 325.

Occurs at Margharita, also in the Naga and Karen Hills, and at
Momeit, extending in all cases to a lower level than the other species
of Ilerda. In Chittagong, Doherty has taken it at sea-level.

ILERDA ANDROCLES.

Thecla androcles, Westw. Gen. Di. Lep. ii. p. 487.

I. hewitsoni, Moore, MSS.

This is the green species common in Sikkim from 5000 to 7000 feet
which I supposed to be J. androcles. I have it from Kulu and
Nepal; numerous specimens were taken in the Naga Hills not below
6000 feet. These differ from the Sikkim specimens in having the
wings in some cases almost without the green shining scales which
cover a large part of the wings in Sikkim, and these scales seem
of a purer green without any blue tinge; but I cannot see my
way to distinguish them, as the amount as well as the tinge of
the green scales varies. I have two specimens from Western China,
taken by Pratt at 5000-6000 feet, which agree with the Naga
males. I cannot distinguish the females from those of I. brahma,
with which this form may possibly interbreed, as the two species
occur together in Sikkim, though both here and in the Nagas the
range of I. brahma seems to be rather lower.

Two males and two females from the Karen Hills which agree
with a female named ‘“? burmana”’ by Moore from Akyab, and also
with four males and a female from S.E. Borneo and Pulo Laut ; there
is no appreciable difference in the colour of the underside. All these
three females have the same venation as the male of Arrhenothrix,
of which the female remains unknown, and want the fourth branch
of the subcostal.

ARRHENOTHRIX PENICILLIGERA.

A. pencilligera, de Nicév. Butt. Ind. iii. p. 337, t. xxviii. fig. 214

A male from Margharita agrees with one from the Khasias. I am
able to distinguish these specimens from D. vidura only by the
difference in venation pointed out by de Nicéville.

towards the apex of fore wing above. On the hind wing there is a
well-defined dull patch at the base quite free from blue scales, and
the tuft of hairs at the base of the hind margin below, which is
present in all the other Camenas I know except C. cotys, is absent or
very much reduced. The venation agrees with that of C. icetas.

Described from a single male taken on the Karen Hills at 4000-
5000 feet.

CaMENA CLEOBOIDES, n. sp. (Plate XLIV. figs. 4 g,5 2.)

Most like C. cleobis, Godt., but differs in having in the male a
large round velvet patch free from blue scales in the cell of the fore
wing and with raised androconia. It is smaller in size and has the
transverse band on the underside nearer the base and directed more
inwards from the hind margin. The band is pale yellow and there is
more yellow at the anal angle than in C. cleodis. The shining patch
at the base of hind margin of fore wing below, seen in C. cleobis, is
wanting, and there is no trace of the tuft of black hairs in the same
place.

@. Similar, but of a duller paler blue asin C. cleobis, and without
the velvety patch on fore wing.

Described from four males and two females taken in the Karen
Hills. This species is allied to Zolaus iseus, Hew., from Sarawak,
of which Tajuria relata, Dist., is the female. I have this latter from
Nias Island in both sexes and a single worn male from Perak.

The venation of C. eleoboides differs from that of C. cleobis and
C. relata in having only two branches to the subcostal, and it may
perhaps on this account, and owing to the well-marked patch on the
male, form a new subgenus.

A. vulcanus, Butt. Ind. iii. p. 349.

A male and two females from the Karen Hills are unlike any
other form of this genus in my collection, and do not agree with any
of those described in the ‘ Butterflies of India ;? but I am unable to
separate them specifically on account of the great amount of varia-
tion which prevails in this genus, in which I think too many species
have already been made.

Above they resemble A. vulcanus in colour, having a slight tinge of
blue at the base of the hind wing and a few blue scales at base of
fore wing in both sexes. Below they resemble what de Nicéville
calls elima, Hew., and uniformis, Moore, from Kashmir, in the dull

Aph. himalayanus, Moore, J. A. S. B. liii. pt. ii, p. 26; Butt.
Ind. iii. p. 358 note.

I received from Margharita, the Naga and Karen Hills, Momeit,
and Perak specimens which vary considerably, but are no doubt all
forms of what de Nicéville calls A. syama and A. lohita. He separates
these by the shape of the mark at base of fore wing below, which
is entire and clavate in A.syama, and T-shaped, hook-shaped, or absent
in A. lohita, I found, however, in a series of Sikkim specimens, this
character too variable to be used as a distinguishing feature ; and
though the males are distinguished by the bright dark purple of
their upperside, yet one from Momeit is entirely without a trace of
this, as the females usually are, though agreeing below with the rest *.

APHNEUS SANI, var.? (Plate XLIII. fig. 6, 2.)

A. sani, de Nicéy. J. A. S. B. lvii. pt. ii. p. 282, t. xiv. 7 Q ;
Butt. Ind. iii. p. 307.

Three females from the Karen Hills most resemble the female of
A. sani from Sikkim, having the same grey-blue on both wings, but
the orange patch in the fore wing is entirely wanting. Below they
also resemble A. sani, but are lighter in colour. It is impossible to
separate them without a larger series and comparison of both sexes.

1 Mr. de Nicéville, in a letter, maintains the distinctness of 4. syama and
A, lohita, which were defined by Horsfield ; and as his material is far larger
than my own in this genus, and has been most carefully studied by him, I am
not disposed to dispute his opinions.

to, and perhaps identical with, 7’. marciuna of Hew. ; but, judging
from the single specimen I have of the latter from Pulo Laut,
it can be separated by the much greater amount of black at base of
fore wings, on inner margin of hind wings, and on the central stripe
of the fore wing, which in my males of 7’. miniata is a line on the
vein only.

Two males of this lovely species were taken by Doherty at
Thandaung in the Karen Hills at about 4500 feet elevation in April
1890. They appear to be quite distinct from C. elegans, which was
found in the same locality, and may be distinguished best by the
colour and arrangement of the beautiful markings of the underside,
which are easier to figure than to describe. On the upperside the
colour is a little brighter than in C. elegans, the black border of the

_ fore wing not broader at the apex. From C. dubases, Hew., it is
distinguished by the absence of a costal border on the fore wing,
its smaller size, and the different markings below.

intermediate between the Burmese and Sikkim specimens.

Three males were sent from the Karen Hills, one of which was

As, however, all three agree perfectly in the very peculiar markings
of the underside, and there were no examples of R. schistacea in
the collection, I think this must be a new species, of which I
am, however, unfortunately only able to describe the male as
follows :—

6. Above same size and colour and blue gloss as R. schistacea,
but darker. Below chalky white with yellow tinge, with a large
lead-coloured patch in the centre of fore and hind wings ; a broad
transverse submarginal band of similar colour on both wings from
costa to inner margin ; a narrower and paler marginal band. A tinge
of fulvous at aval angle; the lobe black, with indistinct pale fringe
extending above the tail, which is black with white tip.

Mr. de Nicéville’s supposition that these names would prove
synonyms is correct, as I have a male from Perak named by himself,
together with two females from East Pegu, which agree with it in
the yellow colour of the underside, and with a female from Barakhal,
Chittagong, taken by Doherty and alluded to by him in writing of
D. barthema. Rapala suffusa is a perfectly good species, and the
female may be known from the female of F. xenophon by the pale
yellow of the underside.

1 have another species with pale yellow underside in both sexes
from the Khasia Hills which is a Deudorix, having no sexual mark in
the male, and is larger than R. suffusa, but though I cannot discover
a name for it the specimens are not good enough to describe.

Doherty sends five specimens of this very distinct species from the

like R. wenophon, but of a more orange tint, with a broad black
border on both fore and hind wings, the latter fringed towards the
anal angle, and more conspicuously on the inner margin, with white ;
a dark streak runs from the base of the tail parallel to the inner
margin. Beneath, the fore wing is dull silvery white, tinged with
brown towards the costa and outer margin. Hind wing the same,
with an obscure row of spots towards the anal angle. The anal lobe
and a large round spot above the base of the tail black, a short
broken line from near this towards the inner margin.

Frons, palpi, and breast white; abdomen fulvous. Head and
thorax black.

Below dull vinous brown, with a short double bar at the end of
cellin both wings; a single basal spot and cluster of three other spots
beyond the bar on hind wing ; a double streak from near these towards

bar on the fore wing, on the other a similar one near the costa of
hind wing. Frons and underside of body and abdomen whitish ;
above black.

with Distant’s good illustration and with a single pair from Pulo Laut,

nearly allied but, as I think, distinct species, which also occurs in Pulo
Laut, and may be Hypolycena amba, Kirby, of which neither Hewit-
son’s nor Distant’s figures are clear in the distinctive points. In this
the male has the costa of hind wing broadly black, the purple on fore
wings more diffused, the markings of the underside more broken,
and the colour of the base much paler; the tails and hind wings
with broad white fringes. If this proves constant, as it is in four
specimens I have, the Pegu and Perak forms may be called
S. amboides.

whilst in many of the allied species the females are taken very

CHOASPES BENJAMINI, var.

Thymele benjamini, Guér. Del. Voy. Inde, ii. p. 79, t. 22. 2, 2a
(1843).

There are two forms of this which may be distinct, but I have a
series of them only from Sikkim. The one I take to be the typical
form is of a greenish shade, but not constant, some specimens being
lighter and some darker ; and this I have from the N.W. Himalaya,
Sikkim, the Khasias, Nilgiri Hills, and Japan, and Moupin in East
Tibet. Another is metallic bluish on the thorax and base of both
wings, sometimes with a tinge of green, and the rest of the wings,
except anal area and fringe, black. This I have from Sikkim and
the Naga Hills. These differences may be sexual; but it is very
difficult to be sure of the sex in this genus.

Pulo Laut, Borneo. The Perak specimen is darker than the other
three, showing the same tendency to vary as C’. benjamini, to which
it is closely allied. It may, however, be distinguished by the greater
extent and paler colour of the yellow border and larger yellow lobe
of the hind wing, and also by the difference in the black markings
on the yellow beneath.

Ismene subcaudata, Feld. Reise Nov. t. lxxii. figs. 20, 21, from

A single male from Bernardmyo, which differs from Moore’s
description in wanting the yellow discal spot above, though it shows
below. The shape of the hind wing is different from his figure,
being more lobed, but not so much so as in Choaspes benjamini.

A pair from the foot of the Karen Hills. The absence of the
red costal streak is not a mark of the female, as Moore says; both
in the Karen Hills specimen and in Ismene fergusoniz, de Nicév., from
South India, this streak is quite conspicuous; but according to
de Nicéville it is highly deciduous in all species of Ismene.

A male from the Karen Hills and a much larger specimen, which
I take to be the female, from Perak. The latter has the base of
fore wing and great part of the hind wing shot with steely purple or
green as in P. hyela; but the underside, which agrees precisely with
that of the male, is free from the striation which is seen in P. hyela
and to some extent in the type of P. rudolphei. I am not at all sure
whether P. rudolphei is a good species, the extent of yellow in the
fringes and hind wing being variable in P. hyela, with which it other-
wise agrees. If the underside is constant, what I have here called
P. rudolphei would be a new species, but the material existing is not
sufficient to decide the point.

PIsOLA ZENNARA.

Of this species, which I recently supposed to be confined to

Two males from Perak, which agree with Distant’s figure and with
specimens from Pulo Laut, Borneo. I have not, however, been able
to compare them with specimens from Tenasserim, whence the type
came. The species seems nearest to P. austeni, but may be distin-
guished from that, and from all other species in my collection, by
the dark chocolate colour of the underside.

of three apical spots. ‘They also agree with some Andaman specimens

Four males from Bernardmyo differ from all my Sikkim specimens
in having the band of the fore wing distinct on the hind margin,
while in those from Sikkim it is faint or wanting ; also in having two
glassy spots above the large one in the middle of the fore wing, instead
of one small one. The apical spots are also larger and better marked,
agreeing in this respect with one female from Sikkim. As, however,
there is some variation in all these points in Sikkim specimens, I do
not think there is enough difference between the two forms to justify
their separation.

There seem to be three forms of this common butterfly, but
I think they run into each other and are hardly separable. The
first has two black spots within the white field of the hind wing and
large marginal oblong dashes ; I have it from the N.W. Himalaya,
Nepal, and Sikkim, and one from the Naga Hills. The second
has no spots within the field, and occurs in Sikkim, Bhutan, the
Naga Hills, and Tenasserim. The third, of which I have a
female marked 7. menaka by Moore, I have only from the Karen
Hills. It has the spot in the white field, but the marginal spots
small, round, and separate, not united into a band as in the other two.
From Malabar I have only one specimen, which combines the
characters of the last two. From Pulo Laut I have two specimens,
of which one is like 7’. menaka, and the other has the marginal spots
of the hind wing almost absent.

Four specimens from Perak and one from Margharita have the
white outer band of the fore wing spotless as figured by Distant,
whilst two from Perak, one from the Karen Hills, and one from
Burmah have two black spots on the white. There is also some

Pterygospidea syricthus, Feld. Reise Nov. iii. p. 530, t. Ixxii. 22,

Four specimens from Bernardmyo are so very small that they
might be supposed to be another species, especially as the white
marks at the base of the hind wing above are almost obsolete ; but
the identity of the position of all the spots and the peculiar shaped
hind wing incline me to believe that they are only a form of
A, syricthus, which I also have from Bhamo, the Shan Hills, and Java.

C. phaneus, Hew. Descr. Hesp. p. 14 (1867); Dist. Rhop. Mal.

There are two forms of this species which seem very distinct, if their
colour only is regarded; but I cannot see any difference in the
markings by which to separatethem. The one figured by Distant is
bright orange-brown ; of this form I have two pairs from Kast Pegu
sent by Doherty, which agree with his type of C. Jalita in my col-
lection, taken in the Chittagong Hills.

Of the other form, which is of a much darker, more chocolate-
brown, I have two females from Perak which agree with Hewitson’s
type from Borneo, and two males from Pulo Laut, Borneo. Celenor-
rhinus omeia, Leech, from West China, is nearly allied, but is olive-
brown and shows no black spots on the hind wing.

Doherty sent two large males from Perak which agree with
Felder’s plate. Also a smaller specimen which may belong to a
distinct species, and if so will bear the name H. Jatoia, Hew., or
P. helena, Butl., as it agrees with the type of that species from
Sarawak and with others from Pulo Laut, Borneo.

There appears to be much variation in this genus, and I can see
no characters which seem sufficiently constant to separate these
forms.

Var. MARGHERITA.

Plastingia margherita, Doh. J. A. S. B. 1889, p. 131, t. x. 5.

I have the type of this species together with another from the
Naga Hills and three from the Karen Hills. On the Naga specimen
is a ticket in Doherty’s handwriting, “probably not distinct from
H. latoia, Hew.” I may say, however, that though I cannot follow
the characters given by Doherty in separating P. margherita from
P. callineura, I can distinguish all these five specimens from any I
have from Perak or Borneo by the colour and pattern of the under-
side, though none of them are quite fresh specimens, and I believe
it will be found that this form is constant as a local race, if not as
a species.

A single specimen from the Karen Hills, which I believe to be a
male, agrees with the plate except that the discal and apical spots of
the fore wing are double. I have the same species from Pulo Laut.
According to de Nicéville this species is the same as P. tessel/ata, Hew.,
which name has priority.

Four specimens from Perak which agree with Hewitson’s type
from Borneo and also with Druce’s description; they are not unlike
the spotless var. of NV. alysos, but have no apical spot on fore wing,
the transparent band shorter, and are of a deeper brown, almost pure
black, with bluish instead of yellowish tinge in the band.

Most of the specimens from Perak which I refer to this species
have no spot beyond the band, and would by some be considered
another species. I have, however, similar ones from Sikkim, and one
Perak female has a single spot as usual in NV. alysos, another having
the additional spots which are found in P. paralysos, Moore. An
allied species has been described as P. monteithi by Wood-Mason and
de Nicéville in J. A. S. B. iv. p. 391, t. xviii. 3, 3a 9; another as
P. albifascia, Moore, P. Z. S. 1878, p. 843, t. lili. 3; in neither
of which can I discover any characters justifying their separation.

CoLADENIA DAN.

Pap. dan, Fabr. Mant. Ins. ii. p. 88.

Hesperia fateh, Koll. Hiigel’s Kaschm. p. 454, t. xviii. 5, 6.

I am unable to define two forms of this insect, though there
appear to be two races—one small and dark, which occurs in Perak,
Burmah, and the Karen Hills; the other, from the North-west
Himalayas and Sikkim, is larger and brighter. Intermediate forms,
however, are common in Sikkim ; and the Javan variety has the band
of spots much more golden, and seems more distinct than either of
the others.

a female and not, as described, a male.

iv. p. 180 (1889).

? C. pyrrha, de Nicév. 1. c. p. 181, t. B. 11 9.

What I take to be a var. of this species was taken in the Naga
Hills by Doherty at 6000-7000 feet. It has the two spots nearest
the hind margin of the fore wing larger and paler in colour, the outer
one being whitish as in C. maculosa, Feld. The markings of the
underside are also clearer and paler than in P. pulomaya, but one
specimen of the latter from the Naga Hills is like the Sikkim form.
I remain in doubt as to whether this is only a variety of P. pulomaya,
or whether it is C. pyrrha, of which de Nicéville figures only the
female, and this is more like what I call C. sumitra.

? C. plagifera, de Nicéy. 1. c. p. 182, t. B. 13 Q.

? C. patula, de Nicév. 1. ¢c. t. B. 4 2.

I cannot follow de Nicéville in his descriptions of these species.
Perhaps what I call C. sumitra is one or other of them ; but he says he
knows C. sumitra from the description only. My C. sumitra occurs also
in the Naga Hills, and is distinguished from the last by the partially
white club and shafts of the antennze, and by the absence of the yellow
spot near the base of the fore wing. I have a female from Ber-
nardmyo which nearly agrees with the figure of C. patula, but unless
Iam mistaken these species are more variable than de Nicéville
supposes.

CELZNORRHINUS PERO.

’ C. pero, de Nicév. 1. c. p. 183, t. B. 12 ¢.

This seems a good and distinct species, but I cannot be sure that it
is C. pero. I have two fresh males from the Naga Hills and a female
which may belong to C. sumitra; they agree fairly with the plate and
better with the description of C. pero; but some of the points touched
on by de Nicéville for distinguishing the species seem inconstant,
and it is impossible to decide without a large number of specimens
from different localities.

CELZNORRHINUS CLITUS.

of fore wing, and longer olive hairs on inner half of hind wing.
Spots glassy white on fore wing, bright yellow on hind wing,
constant in colour and position as figured in three specimens. Cilia
of fore wing and of hind wing as far as second median vein con-
colorous with the wings, on the rest of the hind wing they are
yellow with a trace of brown at the end of the veins.

Below the same as above. Antenne black, mixed with yellow
above. Palpi and breast beneath pale yellow. Thorax clothed with
olive hairs. Abdomen black, ringed yellow.

Expanse 52 mm.

Described from three specimens taken at Bernardmyo in May by
Doherty.

After what I have just said of the variability of the species of this
genus, it may be thought unwise to describe another, but this is so
distinct from any in my collection that I have no doubt of its being
a good one. The fringes of the hind wings, like those of maculata,
from which it differs in its larger size and much longer, more
pointed wings, will distinguish it from any Indian species’.

* Since this was written I find that the species has been already described
by de Nicéyille, so I adopt his name,

A pair from the foot of the Karen Hills, which agree with the
figure and description except in having three apical dots joined
together on the fore wing, instead of two as in the type from Rangoon.
The female does not differ from the male except in the slightly
broader wings, and has the fringes concolorous with the wings, and
the antennze without white on shafts or club; the palpi are white
below.

Seems common at Perak; I have it also from East Pegu, Ten-
asserim, and Tavoy. It is variable in size and in the length and
breadth of the yellow band of the fore wing, but seems to be
distinguished from the next species by the deeper black of both
wings, and the narrower band and the absence of the gem-like spots

I have this also from Perak, where it seems not uncommon. It
agrees with specimens from Pulo Laut, Borneo. I cannot follow
Distant in his generic separation of this species from the last.

ASTICTOPTERUS LADANA. (Plate XLIII. fig. 4, 3.)
Carystus ladana, Butl. Trans. Ent. Soc. 1870, p. 502.

Three specimens from Perak agree with the type from Borneo
in the British Museum. Above they are very like A. gemmifer, but
are easily distinguished by the yellow colour of the legs, palpi, and
abdomen below, and by the orange tinge on the inner margin of the
hind wings below. I do not know in what genus to put this species.
Carystus is a name of Hiibner’s adopted by Butler, who puts in the
genus four South-American species.

ASTICTOPTERUS SINDU. (Plate XLIII. fig. 3, ¢.)

A. sindu, Feld. Wien. ent. Mon. iv. p. 401 (1860).

A single specimen of this small species from Perak has the band
of the fore wing less developed than in specimens from Borneo. It
is distinguished by the colour of the hind wing below, which is
sprinkled with yellow scales, from A. zanites or A. gemmifer.

I believe there are two species confused under this name, of which
one may be the A. jama of Felder; but what Distant calls A. jama,
Rhop. Mal. p. 401, may be 4. subfasciatus. The one is in the
male sex plain unspotted black on both surfaces, with some green
scales on the hind wing below; the female has two spots at the
apex of the fore wing. I have it from Sikkim, Bhutan, the
Khasia and Naga Hills, Margharita, the Shan Hills, Perak, and
West Java.

The other has the underside dull brown with some darker
markings on the hind wing below, two or three glossy spots in both
sexes near the apex and another below it beyond the cell.

This I have from Burmah, the Karen and Shan Hills.

This fine species seems not uncommon at Perak, and according to
a note of Doherty’s the male gives out a pleasant aromatic smell.
The female differs in being of a paler brown colour.

being of a paler brown, which does not seem to be the case in my
Sikkim specimens.

KERANA AURIVITTATA.

Plesioneura aurivittata, Moore, P. Z. S. 1878, p. 483.

One specimen from the Karen Hills, one from the Naga Hills, and
several from near Bernardmyo seem to belong to this species, which is
distinguished from P. cameroni, not by the shape of the band, but by
its colour, which is pale golden like that of P. dhanada, Moore, from
which it is distinguished by the larger size and different shape.

Kerana aurivittata, var. cameroni, Dist. Rhop. Mal. p. 403,

Five specimens from Perak are easily distinguished from the last
by the smaller size, different shape, and by the band being of a
much deeper golden colour. The band is also wider, which makes
the spots at the apex look nearer to it than in K. aurivittata. The
fringe of both wings also is plain and unspotted, whilst in the latter
a small part of the fringe of the fore wing opposite the end of the
band is pale as in K. dhanada.

Kerana? DHANADA.

Plesioneura dhanada, Moore, P. Z. 8. 1865, p. 789.

Three specimens from the Karen Hills which agree with one from
Tenasserim and one from Khasia, in my collection. This species
was incorrectly identified in my list of the Sikkim butterflies; where
I put it with a? as a synonym of C. dan, but I have one specimen
sent me by Médller from thence which differs in the band being
much shorter outwardly and narrower on the costa. The underside,
with the fringe of the hind wings, easily distinguishes this from
either of the last two species.

Three males from Perak and one from the Karen Hills. What I
have under this name is plain dull black above like 4. butleri, which
it resembles in shape, but differs in having no brush of hairs on the
hind wing below, and in having pale obscure spots on the underside,
of which six are near the apex of fore wing and five or six on the
hind wing; there are also two purplish-grey bands, sometimes very
faintly marked, across the hind wing below. I have the same species
from Akyab, Moulmein, Borneo, and the Nilgiri Hills.

LOBOCLA LILIANA.

Plesioneura liliana, Atk. P. Z. S. 1871, p. 216, t. xii. 2.

Abundant in the Karen Hills at 4000 feet.

This is nearly allied to and perhaps only a local race of L. bifasciatus,
Brem. & Grey, of Northern and Central China, with which I think
Lobocla casyapa, Moore, is synonymous ; but as all my specimens are
separated by the larger size, blacker colour, broader white band,
and more apical spots, I keep it as a distinct species. These two
species, together with Hudamus germanus and E. nepos, Oberthiir,
and E. simplex, Leech, all from China, form a group which seems to
have much affinity if not to be congeneric with the N. American
Eudamus, which Moore in describing Lodocla does not mention. This
genus and Erynnis, Schrank, are the only two that I know of in India
which have the costa of the fore wing in the male folded over on to
the upperside of the wing.

1892.] DR. H. GADOW ON GIGANTIC LAND-TORTOISES. 665

December 20, 1892.
Osbert Salvin, Esq., F.R.S., Vice-President, in the Chair.

A letter addressed to the Secretary by Dr. A. B. Meyer, C.M.Z.S.,
dated “Royal Zoological, Anthropological, and Ethnographical
Museum, Dresden, December 8th, 1892,’’ was read.

Dr. Meyer said :—“ Not being aware that Semnopithecus nemeus
has been recorded from the island of Hainan, but only from Cochin
China, I beg to state that the Dresden Museum has recently re-
ceived a male specimen of this Monkey together with other objects
from there. I cannot perceive any differences in this specimen from
the descriptions and figures of the continental animal, but may
remark that the specimen is in a bad state and that the hair of the
head is partly torn out.”

A communication was read from the Rev. T. R. R. Stebbing,
entitled ‘‘ Descriptions of nine new Species of Amphipodous Crus-
taceans from the tropical Atlantic.” This communication contained
descriptions and figures of some Hyperidean Amphipoda collected
by Mr. John Rattray when on board the ‘ Buccaneer’ at the beginning
of 1886. The specimens had been taken in the tropical Atlantic
off the west coast of Africa, by a series of ‘“ tow-nettings”’ carried out
at the expense of Dr. John Murray and Mr. J. Y. Buchanan.

In the genus Scina, Prestandrea, seven new species were instituted,
which were named respectively: acanthodes, stenopus, cedicarpus,
concors, rattrayi, similis, and uncipes. Of these S. acanthodes was
remarkable among the Hyperidea for the spine-like processes along
the back, while S. stenopus was distinguished for a slenderness of
the body and appendages unusual in the genus. The earliest example
of Scina known to science had been obtained by Banks and Solander
on Captain Cook’s first voyage round the world and had been figured
at the time by their ill-fated ‘natural history painter ’ Sydney
Parkinson. Since then the genus had yielded few specimens but
many species, the distinctive characters depending chiefly on certain
parts of the organization which appeared to be uncommonly variable.

In the genus Rhabdosoma, Adams and White, two new species
were established, named respectively pirata and brachyteles. The
generic name Rhabdosoma was upheld against Ayphicéphale and
Xiphocephalus, and it was argued that the family name Xiphoce-
phalidze, referring to the sword-like head, should consequently give
place to the equally appropriate name Rhabdosomida, referring to
the rod-like body.

Dr. Hans Gadow, F.R.S., gave an account of the remains of
some gigantic Land-Tortoises recently discovered in Mauritius,
along with the bones of the Dodo described in a previous com-

munication by Sir Edward Newton and himself. The remains

of the Tortoises were referred to Yestudo indica, T. triserrata,
T. inepta, and to two new forms proposed to be called 7. sauziert
and 7’. soumeiret, the latter being possibly related to the gigantic
Tortoises of Aldabra. Along with these Tortoises were found
numerous bones of the extinct Lizard, Didosaurus mauritianus, of
which an account was also given.

In the present paper I desire to offer to the Society some notes
upon sixteen species of Earthworms, for the most part undescribed,
which have come into my hands during the last year or two through
the kindness of friends resident abroad, and from the Royal Gardens
at Kew, through the kindness of Mr. Thiselton Dyer. The latter
were received by me alive, and were carefully preserved for section-
cutting ; the specimens sent from abroad were, however, in most
cases also well preserved.

1892. ] SPECIES OF EARTHWORMS. 667

I. Family ACANTHODRILIDE.

The majority of the new species of Acanthodrilide which I describe
in the present paper are from New Zealand ; I owe these specimens
to the great kindness of Prof. T. J. Parker, F.R.S., and of Mr. W.
W. Smith, of Ashburton.

The species of Acanthodrilidee found in New Zealand have been
hitherto referred to three genera; six years ago I described, under
the name of Neodrilus monocystis*, an Acanthodrilid differing from
the typical forms (included within the genus Acanthodrilus) by the
presence of but a single pair of atria and spermatothece ; this worm
has been lately re-investigated by Dr. Benham?, who has confirmed
and extended my original account. I may add that I have within
the last few months received some more examples of the same worm ;
there is accordingly no longer any doubt as to the characters of this
species; it is not, as I at first thought it might be, a mere abnor-
mality of such a species as Acanthodrilus dissimilis. Whether this
Earthworm should be really referred to a distinct genus is another
matter. I prefer, however, to leave the question alone for the present.
In any case there can be no doubt whatever about the generic
distinctness of Deinodrilus and the recently described Plagiocheta’*.
This latter may conceivably be identical with Hutton’s Megascolex
sylvestris*; at any rate that species is stated and figured by Hutton
to possess numerous setee arranged in couples, which is the principal
external character of Benham’s Plagiocheta.

The remaining Acanthodrilidee have been all referred by me’ to
the genus Acanthodrilus. This genus comprises altogether some
40 species, of which 8 are inhabitants of New Zealand. Forty species
are not, perhaps, an unwieldy number for a single genus: it has never-
theless been divided into two genera, Acanthodrilus and Benhamia,
by Michaelsen ; Benhamia, it should be remarked, includes Benham’s
Trigaster. In distinguishing the two genera Michaelsen has not
considered the characters of the New Zealand Acanthodrilidze.
Benhamia is the name applied to those Acanthodrilidee with a
“ diffuse” nephridial system—that is, in which the nephridia are not
paired, but open on to the exterior by numerous pores; added to
this character, Michaelsen originally called attention to the fact
that the species with a diffuse nephridial system possess a pair of
gizzards, or, as in Trigaster, three gizzards; later he was led, by a
consideration of the species Acanthodrilus schlegelii, to reconsider the
definition of the genus and to use, as part of the generic diagnosis,

the phrase “as a rule more than one gizzard.” According to this
definition my Acanthodrilus multiporus should be referred to the
genus Benhamia ; and yet it differs from the African species (Africa
is at present the headquarters of the genus) in a number of cha-
racters: there are no penial setz; the calciferous glands are limited
to a single pair ; the dorsal vessel is double ; the sete are not strictly
paired, but separated by alittle distance. There are two other species
described in the present paper which agree with 4. multiporus in
these points; a fourth species, Acanthodrilus antarcticus, agrees
with A. multiporus in most of these characters, but not in all.

It has penial setee; the two pairs of calciferous glands are in
segments xv., Xvi., and there is a smaller gland in xiv.; only the single
gizzard and the distant sete distinguish this species from the majority
of those assigned by Michaelsen and others to the genus Benhamia.
In spite, however, of the near resemblance of this particular
Acanthodrilid to Benhamia, I am not inclined to refer it to that
genus. In the first place it is possible that Benhamia schlegelit, which
is stated to have but one gizzard, has really two; the two gizzards
in this genus are often so close together that it is not a little difficult
to make out that they are really two; the interval of soft-walled
cesophagus between them is reduced to the lowest terms in many
eases. In the second place, Acanthodrilus antarcticus is so like
A. multiporus in other particulars that it would be doing violence
to their obvious relationship to separate them*. Taking into account
also the distribution of these species it seems reasonable, now that
the old genus Acanthodrilus is being broken up, to associate the
New Zealand species here referred to into a geuus distinct from
Benhamia, which may be termed Octochetus. It will be thus
defined :—

Octochetus, nov. gen.

Prostomium not continued by grooves on to buccal segment ; clitel-
lum siti.—vix. (wx.) ; male pores on prominent papille ; sete distant ;
ventral sete present on segment xviii. ; a single gizzard in vi., or v.
and vi., or v.; calciferous glands one or two pairs, in xvit., xviii., or
xv. and xvi. ; typhlosole well developed ; nephridia diffuse, a mucous
gland present ; dorsal vessel double from seventh segment onwards ;
diverticula of spermatothece very minute.—Distribution: New
Zealand.

There is another character to which comparatively little attention
has been paid, which may prove to distinguish the genera Benhamia
and Acanthodrilus. In the two species of Benhamia described in
the present paper, as well as in B. stuhlmanni (for an opportunity
of examining which I am indebted to Dr. Michaelsen), there are
no sete upon the xviiith segment where the ventral pair should

1 Tt may turn out that the position of the gizzard distinguishes my genus
Octochetus from Benhamia; I am aware that Rosa speaks of the gizzards of
B. scioana as occupying segments y, and vi.; this is at present the only excep-
tion to the rule that in Benhkamia the gizzards are a segment or two further
back.

be (woodcut, fig. 1); these setae are also absent from the xviith and
from the xixth segments, or rather they are there replaced by the
penial setee. In all the species of Acanthodrilus, on the other hand,
which I have been able to examine, the ventral sete are not missing
from the xviiith segment, though they are not present on the xviith

and xixth segments, being there replaced by the penial setze; this
is also the case with the genus Octochetus; in two of the species
of that genus at any rate, viz. O. multiporus and O. antarcticus
(woodcut, fig. 1), the ventral pair of sete of segment xviii. are

670 MR. F. E. BEDDARD ON NEW [Dec. 20,

present and quite normal; on segments xvii. and xix. the ventral-
most seta is present and unmodified. Octochetus antarcticus is
furthermore remarkable for the fact that the sete of the xviith and
xixth segments appear at first sight to be present and normal; as
a matter of fact, the outer seta of the ventral pair is replaced by the
penial sete, which occur exceptionally in this species: these sete
are very much smaller than in Acanthodrilus dissimilis for example,
and can hardly be seen until they are examined microscopically, but
they are undoubtedly there. The ventralmost seta of the ventral
pair is not absent from these segments as it usually is, but is quite
recognizable; this species is therefore in a less modified condition
than is any other of the species of Octochetus, or Acanthodrilus,
or Benhamia. In A. annectens and A. paludosus, described in the
present paper, there is, as in Octochetus, a single seta ventrad of
the atrial pores.

In all the species of Benhamia which I have dissected, the calci-
ferous glands are different from those of Acanthodrilus or Octochetus.
These glands are (in Benhamia) reniform pouches attached to the
sides of the cesophagus; in Acanthodrilus and Octochetus these
glands present the appearance of swellings upon the course of the
cesophagus. Moreover, in Benhamia there appear to be always
three pairs of calciferous glands which may, perhaps, prove to be
always in segments xv., xvi., and xvii.; they have been for the
most part described as in these segments, and it is possible that in
those cases (e.g., B. biittikoferi, Horst) where they are stated to
occupy the xivth, xvth, and xvith segments, a mistake of one segment
may have been made; anyhow the three pairs seem to be cha-
racteristic, and nearly, if not quite, universal.

In the two species of Benhamia which I describe in the present
communication, the spermatothece have a peculiar form, which is
indicated in the accompanying drawing (Plate XLVI. fig. 7); the
pouch is constricted in the middle, the constriction not coinciding with
the attachment of the single diverticulum. Michaelsen has figured the
spermatotheca of Benhamia stuhlmanni*, which shows precisely the
same structure, but does not remark upon it in the text of his paper.
This peculiar form of spermatotheca is not, however, found in all the
members of the genus Benhamia, for Horst figures the spermatothecze
of Benhamia beddardi as like those of the genus Acanthodrilus’.

. For the purpose of comparison I subjoin a definition of Ben-
amia:—

Benhamia, Michaelsen.

Prostomium sometimes continued by grooves on to buccal segment ;

xv.—axvir. ; nephridia diffuse ; dorsal vessel single ; penial sete nearly

always present ; no ventral sete upon xviii— Distribution : Tropical
Africa, Tropical America, and India.

The species Acanthodrilus nove-zelandie, A. dissimilis, A, rose,
and .A. smithi (to be described in the present paper) I refer to the
genus Acanthodrilus sensu stricto. I am doubtful about Acan-
thodrilus annectens, a species which I described some years since’.
In possessing paired nephridia it agrees with Acanthodrilus (s.8.),
but it has the “ mucous gland” of Octochetus, and the gonads are
placed in contact with the funnels of their ducts, as is the case with
three of the species which I refer to this genus, Octochetus ; it has
the further peculiarity that the sperm-ducts run in the thickness
of the body-wall, a peculiarity which it apparently shares with the
genus Octochetus, but which, among other Oligocheeta, is rare, and
only found, so far as I am aware, in Diplocardia communis and
in the not nearly allied form Siphonogaster. The absence of cal-
ciferous glands is occasionally met with in Acanthodrilus. The
existence of this species serves to indicate how closely allied are the
forms which do, and the forms which do not, possess a diffuse
nephridial system. Another instance of the same approximation of
species to each other which differ in their excretory system is afforded
by Benhamia beddardi and Acanthodrilus ungulatus; in both of
these there is an elaborate arrangement of modified setee and glands
appended in the neighbourhood of the spermatothecee. These facts
possibly indicate that the passage from the diffuse to the paired
nephridia may occur more than once in a genus, and of course dis-
count the value of the modifications of the nephridial system in
classification.

I shall now describe two apparently new species which I refer
to my genus Octochetus :—

1. Octochetus thomasi, n. sp.

I have received on various occasions during the last few years
examples of a small-sized Acanthodrilid from New Zealand, which I
have hitherto confounded with O. multiporus. I regarded these
individuals merely as small specimens of that species. A full-sized
specimen of O. multiporus is a very large worm, measuring, even
in a contracted condition, some 14 inches in length by half an inch
or so in breadth. On the other hand, the worms which I now
consider to represent a new species of this genus are of a much more
slender build. Unfortunately, I am not in a position to give any
exact measurements; the specimens which I possess are none of
them intact. An individual measuring 144 mm. is, I fancy, nearly
complete; the diameter of this worm is not more than 5 mm., and
the body consisted of 230 segments. :

The external characters of the species recall O. multiporus; the
prosiomium is not continued by grooves on to the buccal segment,
That segment and the two following are not annulate; segments

iv., v., Vi. are triannulate, the middle annulus being much the
narrowest ; segments vii., vili., ix. are very much wider (antero-
posteriorly), but still triannulate; so, too, are the segments which
immediately follow, though much narrower. After the clitellum
the segments continue to be triannulate.

The clitellum extends from segments xiii.—xix. ; it is at first com-
plete, extending right round the body; but on segments xvi.—xix.
there is a ventral median area without any glandular modification.

The atrial pores are upon very conspicuous papille; the two of
each side of the body are connected by a longitudinal groove, which
is not straight but has a semicircular outline, the convexity being
dorsal. The oviducal pores are just in front of the ventralmost seta.
The sete are rather distant from each other; a somewhat greater
distance separates the two lateral sete.

I have not seen any dorsal pores.

The pharynx occupies the first four segments of the body; the
gizzard is very elongated, with parallel margins ; it measures 6°5 mm.
in length; the gizzard occupies two complete segments, the fifth and
the sixth. The cesophagus bears in segment xvii. the single pair of
calciferous glands, which present the appearance of an oval swelling of
the cesophagus itself. The intestine commences in the xixth segment.

The septa of some of the anterior segments are, as is so constantly
the case with Earthworms, strengthened and bound together with
thin muscular strips which occasionally pass through one septum
to reach another lying behind it; the number and appearance of
these septa is illustrated in the accompanying drawing (woodcut,
fig. 2, p. 673). The first septum, which is thin and transparent,
divides segments iv./v.; it is traversed by a large number of muscular
threads which bind the pharynx to the parietes: the next septum is
also thin and delicate in texture ; it is attached at the end of the first
third of the gizzard; a good number of the threads which bind the
pharynx to the parietes pass through it. The following seven septa
are thickened; the last of them therefore bounds the thirteenth
segment anteriorly.

The dorsal vessel is completely double; the two tubes of which
it is composed retain their individuality where they pass through
the intersegmental septa. The dorsal vessel is, however, at first
a single tube; it is not until the seventh segment that it becomes
double. In this segment commences the supra-intestinal vessel,
which is large and very conspicuous. In segments x., Xi., Xii., xiii.
are the four pairs of dilated hearts; in a few segments, anterior to
the tenth, are more delicate peri-cesophageal vessels.

There are, as in Octochetus multiporus, a pair of large nephridia
lying close against (in front of) the first septum; from each of
these a slender duct was traced forwards which opens, it may be
inferred, into the buccal cavity; I did not, however, succeed in
seeing the actual orifice. In the rest of the body the nephridia are
also constructed upon the plan which is characteristic of Octochetus
multiporus ; the tufts appear to be massed chiefly round the setz.

Both testes and ovaries occupy the usual segments, but the gonads

-1892.] SPECIES OF EARTHWORMS. 673

are attached to the posterior wall of their respective segments, as
they are in Acanthodrilus annectens and in Octochetus multiporus.
The racemose sperm-sacs are in Xi., xii.
The spermatothecxe are elongated pouches in viii. and ix.; they

appear to have numerous minute diverticula crowded round the
duct near to its external opening.

The atria do not extend beyond their proper segments. A number
of strong muscular bands, such as occur in Octochetus multiporus,
pass from the lateral to the ventral walls of segments, and serve, no

674 MR. F. E. BEDDARD ON NEW [Dec. 20,

doubt, to extrude the papillee already spoken of, on to which the
atrial pores open. ‘There are no penial sete.

This species is clearly most intimately related to Octochetus
multiporus ; indeed it is not a little difficult to separate the two;
the difficulty, too, is increased by the variability of the larger species.
This difference of size is the most obvious difference; and it is, I
think, a difference that must be allowed. The variability of Octo-
chetus multiporus unfortunately concerns those very organs upon
which I had at first attempted to lay stress as distinguishing the two.
In some individuals of Octochetus multiporus the gizzard is limited
to the sixth segment, the second septum lying just in front of it,
attached therefore to the cesophagus; but in other specimens this
septum is inserted on to the gizzard itself, which thus occupies two
segments, as in Octochetus thomasi. In two individuals the single
pair of calciferous glands are in segment xviii.; but in others, as
is the case with Octochetus thomasi, in the xviith. Another
possible distinction between the small and the large species concerns
the dorsal vessel ; in O. thomas, as already mentioned, this vessel
is single until the seventh segment. Ina specimen of Octochetus
multiporus the dorsal vessel was single until the commencement of
the sixth segment only; in this segment it became double; in
another the single dorsal vessel became double at the septum
separating v./vi., but immediately after the two halves became fused,
to again divide at about the middle of the seement. The shape of
the gizzard and its relative length in the two species does appear
to differ; in the smaller species it is proportionately longer and
narrower than in the large species.

The next new species cannot by any possibility be confounded
with the foregoing; I name it after Capt. Hutton, who has done
so much in describing the fauna of New Zealand.

2. Octochetus huttoni, n. sp.

I had a number of examples of this species sent to me by
Mr. W. W. Smith; they were all of approximately the same size;
an individual selected for accurate measurement was 130 mm. in
length by 7 mm. in breadth at the clitellum. It consisted of 233
segments.

The colour during life was pink, the clitellum being white; this
colour is due to the fact that the species, like O. multiporus, had
no pigment in the skin.

The anterior segments are much annulated. After the clitellum
there is also, though to a less extent, an annulation of the segments.

The clitellum occupies segments xiii.—xix. (xx.).

The atrial pores are borne upon a very prominent fold over-
hanging on each side the ventral surface, which in this region
appears in consequence as if hollowed out. The two pores of each
side are connected by a longitudinal furrow.

The prostomium is short and wide, and is not continued by grooves
on to the buccal segment, which is marked by numerous furrows,

The sets are in pairs not closely approximated,

1892.] SPECIES OF EARTHWORMS. 675

The dorsal pores commence between xi./xii.

The gizzard measures 8 mm. in length, and appears at first sight
to occupy about four or five segments; it really corresponds to
segment y., which is increased in size at the expense of neighbouring
segments for its reception. The calciferous glands are in xv. and
xvi.; they have the appearance of being merely dilatations upon
the course of the cesophagus, which is the case with the other
species of this genus.

The intestine begins in xviii., but the typhlosole (which is very
prominent) does not begin before segment xx.; it ends at about 60
segments before the end of the body.

The first septum is in front of the gizzard. After the gizzard are
six stout septa, and, following these, are two which are rather more
developed than the rest, but not as strong as those which precede
them. The nephridia are diffuse, and there is a particularly dense
mass of tubes in the anterior segments, which seem to represent the
mucous gland of Octochelus multiporus’*.

The dorsal vessel is double, and there are three pairs of hearts
in X.—xii.

All the gonads are attached to the front wall of their segments.

The spermatothecee (in viii., ix.) have a minute clump of diver-
ticula, presenting the appearance of a solid body, about the size of a
pin’s head.

There are no penial sete.

Hab. New Zealand.

This species is evidently perfectly distinct from the last ; it is,
however, clearly referable to the same genus, if this genus be
admitted. The diffuse nephridia, double dorsal vessel, separate
setee, absence of penial sete, and anterior position of gizzard cause
it to resemble the three other species which I refer to the genus
Octochetus. It differs from O. multiporus and from O. thomasi in
the following points :—

(1) The prominence of the atrial pores as seen from the outside.

(2) The position of the gizzard in segment v., and its limitation
to this segment.

(3) The presence of two pairs of calciferous glands in xv., xvi. ;
in this the present species resembles O. antarcticus.

(4) The existence of only three pairs of hearts instead of four.

(5) Six thickened septa instead of seven.

(6) The attachment of the gonads to the front wall of their
segments; in this character 0. huttoni resembles O. antarcticus.

The next species which I describe ig referable to the genus
Acanthodrilus (s.8.).

3. Acanthodrilus smithi, n. sp.

I have been able to examine, though the kindness of Mr. W. W.
Smith, some seven examples of this new species of Acanthodrilus ;
the general appearance of the worm is very different from that of

1 T did not ascertain whether these opened into the buccal cavity as in
O. multiporus.

676 MR. F. E. BEDDARD ON NEW [Dee. 20,

the other New Zealand Acanthodrilide which I have so far had
the opportunity of studying—so different that it was unnecessary
to dissect the species in order to ascertain its distinctness. All the
New Zealand Acanthodrilide, with the exception of the present
species, are either devoid of pigment in the skin, or, if pigment is
present, the worms are of a brownish colour. Acanthodrilus
smithi is (after preservation in alcohol) of a violet colour, the
clitellum being whitish yellow; the ventral surface of the body is
the same colour as the clitellum.

The worms are slender, measuring up to 75 mm. in length with a
diameter of 3 mm. at the widest part of the body. An individual
of this size consisted of 114 segments.

The prostomium completely divides the buccal segment, as it does
in the New Zealand species Acanthodrilus nove-zelandie &e.

The setee are paired and the pairs are equidistant, the body being
thus divided into four equal areas. There is no difference in size
between the setee of different segments.

The clitellum occupies segments xiii.—xix.; it is saddle-shaped,
and is not developed ventrally beyond the outermost of the two ventral
sete.

I could find no dorsal pores.

The nephridiopores are very evident; they alternate in position
from segment to segment, as is the case also with other species of
Acanthodrilus from New Zealand. They sometimes lie in front of
the dorsal, sometimes in front of the ventral setee.. When they open
in front of the ventral setee they appear to be particularly related to
the outer of the two setee; when, on the other hand, they open in
front of the dorsal setze, the orifice is in front of the innermost of
the two setee which constitute the pair.

The spermatothecal pores lie on the border-line between segments
vii./viii. and viii./ix. They lie in front of and to the outside of the
ventral pair of sete.

The atrial pores (see fig. 1, p. 669) are upon segments xvii.
and xix. ; their position corresponds exactly with that of the ventral
pair of setee, which are absent from these segments. The ventral
setee are, on the other hand, present upon the xviith segment; and
the sperm-duct pores lie a little to the outside of and in front of these
sete ; their position therefore corresponds more accurately to that of
the spermatothecal pores than do those of the atria.

The internal structure does not present any special points of
interest, being on the whole very similar to that of the other New
Zealand Acanthodrili.

The nephridia are alternate in position, as in A. dissimilis; this
peculiarity is confined, ‘as regards the genus Acanthodrilus, to the
New Zealand species.

The dorsal blood-vessel is single ; there are four pairs of dilated
hearts, the last of which is in segment xiii.

The alimentary canal is furnished with arudimentary gizzard, which
needs a microscopical examination for its demonstration ; such as it
is, it lies in segment y, There are no conspicuous calciferous glands,

1892. ] SPECIES OF EARTHWORMS. 677

but in segments xiv. and xv. the cesophagus becomes wider, and its
lining membrane much folded and very vascular. This region
evidently corresponds to the calciferous glands of other Earthworms :
all doubt upon the matter appears to be removed by the discovery
of crystals exactly similar to those which occur in the calciferous
glands of other Oligochzeta. The vascularity of the cesophagus is
not limited to these two segments; from the tenth segment onwards
its walls are vascular, though not so folded as in the two segments
xiv. and xv. The intestine commences in the xviiith segment.

The gonads occupy the usual position; the sperm-sacs are in
segments ix., x., xi., xii. The atria are like those of other Acantho-
drilide, and each is provided with a bundle of penial sete. These
sete (Plate XLVI. figs. 9 and 10) are recurved at the extreme end;
the extremity has two delicate wing-like proccsses which, when the
seta is viewed from above, give to the end an oval contour; the tip of
the seta in this aspect is seen to be bifid. The absence of any orna-
mentation upon the set appears to distinguish the New Zealand
Acanthodrilide with the exception of Octochetus antarcticus, where
it is only very slight.

The spermatothece are, as is nearly universally the case with the
Acanthodrilidee (Acanthodrilus [ Diplocardia| communis is, so far as
I am aware, the only exception), two pairs situated in segments viii.
and ix. Each pouch has three small diverticula, one of which is
constantly in front of the septum.

4. Acanthodrilus paludosus, n. sp.

This is a small and slender worm, but I have not preserved any
accurate notes of its dimensions ; it was about an inch in length and
something like 1 mm. in diameter. It was found in a marsh in
New Zealand by Mr. W. W. Smith, to whom I am indebted for the
specimen.

This species is a near ally of Acanthodrilus annectens, which I
have already referred to as possibly worthy of generic separation
from the Acanthodrilidee with paired nephridia.

The present species has the same arrangement of the setee, which
are not modified upon any of the segments of the body. I did not
describe, in my account of Acanthodrilus annectens’, the fact that
only one of the two ventral sete is missing on the segments which
bear the atrial pores, i. e. xvii. and xix. ; the apertures take the place
of the missing outer seta of the ventral couple; on the xviiith seg-
ment both setz of the ventral pair are present ; the pore itself lies
to the outside of the pair. Acanthodrilus paludosus shows exactly
the same arrangement, and both species therefore differ from Acan-
thodrilus smithi and from the other New Zealand species of Acan-
thodrilus in this matter: in them the ventral sete are entirely
absent from the xviith and xixth segments.

The clitellum was not developed, though in other respects the
* worm appeared to be fully mature.

? “On the Structure of three new Species of Earthworms &.,” Q. J. M.S,
vol, xxix, p. 102,

678 MR. F. E. BEDDARD ON NEW [Dec. 20,

The gizzard lies in segments vy. and vi., but only one-fourth of the
organ lies in the anterior segment. Calciferous glands are, as in
A. annectens, totally absent ; the intestine begins in the twentieth
segment. Some of the septa are thickened.

There is a mucous gland, and the nephridia are paired.

The gonads are normal in position; they are not situated on the
posterior face of their segments as is the case with A. annectens.
Opposite to them are the funnels of the ducts, which are like those
of other species and occupy the same segments. The sperm-ducts,
however, agree with those of A. annectens to differ from those of
most other Earthworms, in running within the thickness of the body-
wall ; they retain their individuality until just before the external
aperture.

The atria have no peculiarities of structure; there are no penial
setze ; strong muscular bands run from the lateral to the ventral
parietes in the neighbourhood of the atria, a character which unites
this species and Acanthodrilus annectens to the genus Octochetus:
the presence of these muscular strands is perhaps to make up for
the absence of penial sete; the atrial papilla can possibly be
considerably protruded by their means, and as they (the extruded
papillz) are tapered at the extremity, they can, it is likely, be actually
inserted in the spermatothecal orifice and convey the sperm direct.

The oviducal pores are placed just in front of the ventralmost sete.

The oviducts have no egg-sacs attached to them.

The sperm-sacs are in segments ix., xi., xii.; I could not find
any sac in the intervening segment.

The spermatothecz are, as in all the Acanthodrilide (excepting
only 4. communis), two pairs and lie in the usual segments, i.e. viii.,
ix.; each pouch has, as in Acanthodrilus annectens, more than one
diverticulum ; in the present species there are two, one of which is
rather the larger.

Closely allied to Acanthodrilus annectens as this species un-
doubtedly is, there will be no difficulty in distinguishing it. The
chief points of difference are :—(1) position of gizzard; (2) normal
position of gonads; (3) form of spermatothece.

5. Acanthodrilus falclandicus, n. sp.

Some time since I added* some anatomical details to Michaelsen’s
account of Acanthodrilus georgianus’, which had been derived from
the study of what I believed to be an identical form. More re-
cently Michaelsen* gave reasons for regarding the species described
by myself as not identical with that named by him <Acanthodrilus
georgianus. Dr. Michaelsen has been so good as to send me two
specimens of his A. georgianus, and I have therefore been able to
follow the account which he has given regarding the species.

1892.] SPECIES OF EARTHWORMS. 679

The differences between the two forms may be stated in a tabular
form as follows :—

Sete.—In A. georgianus the distance separating the two sets of the
lateral couple is hardly greater than that which separates
the ventral couple.

In my species, which I propose to call A. falclandicus, the
distance between the lateral sete is markedly greater than
that between the ventral sete.

Nephridiopores.—In A. georgianus these are placed in front of and

below the third seta.
In A. falelandicus these pores are directly in
front of the third seta of each segment.

Gizzard.—Totally absent in A. georgianus.

Rudimentary in A. falclandicus.

Penial sete.—In A. georgianus these have fewer tubercles upon the

extremity and these tubercles have no serrations.

Michaelsen goes on to suggest that my species is possibly identical
with Rosa’s Acanthodrilus bovei. I am not able, however, to adopt
this suggestion, and for the following reasons.

In the first place Acanthodrilus bovei is a much smaller species
than the one named by myself Acanthodrilus falclandicus ; the
measurements of A, bovei are 35 mm. in length by 3 mm. in
diameter ; A. falclandicus measures 60 mm. in length and upwards.

Of A. dovei the prostomium is said by Rosa to extend on to the
buccal segment for about two-thirds of the length of the latter ; the
prostomium is less extensive in A. falclandicus.

The clitellam in A, falclandicus is quite complete, extending
right round the body ; in the species with which it is sought to
identify my A. falelandicus there is a non-glandular triangular area
reaching as far forwards as the xvth segment.

Acanthodrilus falclandicus possesses a pair of papillee upon the
xth segment which lie behind the ventral setee—exactly behind
them. In A. georgianus Michaelsen has described a similar pair of
papillee upon the tenth segment, but not anything is stated with
regard to their position upon the segment except that they lie upon
the seta-line 2. In A. bovei there are such papille, but they lie
between the ventral setze on segments x. and xi.; Rosa also speaks
of an oval area occupying a median position upon the ninth segment.

These differences are, I think, sufficient to distinguish my species
from Rosa’s Acanthodrilus bovei*, though doubtless the two are very
nearly related. In my paper upon the anatomy of this form I
referred to its occurrence in fresh water as well as upon the land; I
have since re-examined more carefully the specimens which occurred
in water, and IJ find that they are really different from A. falclandicus,
though very nearly related ; indeed the differences between all of
these Patagonian Acanthodrilide are not very large.

Ciy. Genova, ser, 24, vol. vii. p. 143.

680 MR. F. E. BEDDARD ON NEW [ Dee. 20,

I name the species

6. Acanthodrilus aquarum-dulcium, n. sp.

I need not trouble to give a detailed description of this species,
but will merely indicate the differences which it shows from A. fale-
landicus. It is in the first place a much smaller species; the
measurements of a full-sized specimen are as follows:—Length
47 mm. ; breadth 3 mm.; number of segments 90.

The species is altogether of a more slender build than A. falclan-
dicus and has thinner body-wall. The two atrial pores of each side
are connected by a groove in which lies the pore of the sperm-duct ;
this latter pore, as in A. falelandicus, is just outside the ventral sete
which are present upon the xviiith segment, though of course
absent or perhaps rather replaced by the penial sete on segments
xvii. and xix. Between the ventral setze on the xviiith and on the
xxth segments are a pair of small papilla. I did not find any
papillze in the neighbourhood of the spermatothecal orifices.

The internal anatomy hardly differs from that of A. falclandicus ;
there are, however, no thickened septa; the sperm-sacs may be
different, but I was not able to make out their arrangement accurately.
I observed egg-sacs in segment xiv. The principal difference
between this species and A. falclandicus concerns the penial sete.
In the present species they have only a very faint ornamentation at
some little distance from the free extremity. The large tubercles
characteristic of A. falclundicus are entirely absent ; there are merely
a series of minute spines with their apices directed downwards.

7. Benhamia whytei, n. sp.

Among a large quantity of insects and other invertebrates collected,
for Mr. H. H. Johnston, C.B., by Mr. Alexander Whyte, F.Z.S., in
Nyassaland was a single example of an Earthworm evidently belong-
ing to the genus Benhamia, which I cannot identify with any of the
African forms described by Michaelsen. The specimen was unfor-
tunately not in a sufficiently good state of preservation to admit of
an exhaustive account of its structure; but I have been able to
ascertain some of the principal characters which serve to discrimi-
nate it from the other African species of the genus.

The specimen is 23 inches long and is of a dark brown colour.

The prostomium is not prolonged over the buccal segment; the
dorsal pores commence very early between segments iii./iv.

The clitellum occupies segments xiiixix.; on the ventral side
the male pores are surrounded by a circumscribed area, as in other
species of the genus; within this area there is no development of
glandular tissue.

The apertures of the atria are as usual upon segments xvii., xix. ;
the orifices are circular and each is surrounded by a circular rim ;
the two apertures of each side are connected by a groove; the
ventral sets of the three segments xvii., xviii, xix. are absent.
Their place is taken on the xviith and the xixth segments by the
penial setze.

1892. | SPECIES OF EARTHWORMS. 681

The sete are strictly paired and are on the ventral surface.

There are two gizzards, whose exact position I am not able to state.

The calciferous glands are kidney-shaped; there are three pairs
of them, in segments xv., xvi., xvii. The intestine commences in the
middle of segment xviii.

The dorsal blood-vessel is single; there are three pairs of hearts,
in segments x., Xi., xil.

Six septa following the gizzard are thickened, but their increase
in thickness is not so well marked as it often is in Earthworms.

The internal anatomy of this species is precisely like that of
Benhamia crassa above described ; the form of the penial setee, which
are the only structures by which some of these Benhamie can be
distinguished, were hardly different from those of Benhamia crassa ;
in the specimen from Dominica they were even twisted into a spiral
at the extremity, there were possibly rather more denticulations
on the end; in the same way the end of the two vasa deferentia of
each side were enclosed in a common muscular sheath.

It may be that the glandular caecum of the buccal cavity will
prove to be a character of generic value. I followed out the ducts
of the mucous gland, and find that each gland opens into the
pharynx by a wide aperture, which has, however, a shorter duct than
in Octochetus multiporus ; the opening is also situated further back
than in that genus; besides the opening into the buccal cavity, the
mass of nephridial tubules, which I have called the mucous gland,
also open on to the exterior by numerous openings.

1 should mention that in this species, as in B. crassa, the last pair
of hearts is in segment xii.

8. Benhamia crassa, n. sp.

Among a number of living Earthworms lately received from Kew,
whither they had been accidentally transported from Lagos, West
Africa, were two very small individuals, measuring about an inch in
length after preservation, which apparently belong to two distinct
species. Their appearance while alive was so very similar that I
regarded them as of the same species, and proceeded therefore to
examine one by means of a series of longitudinal sections, while the
other was cut into two halves and the viscera teased out. I had
hoped in this way to supplement by one method of study the results
obtained by the other. The two individuals, however, turned out to
differ in a slight degree, the difference being possibly of specific
value ; the difference mainly concerned the extent of the clitellum ;
in other points they appeared to agree.

The prostomium is imbedded in the buccal segment, but it is not
continued by grooves over any part of this segment.

The dorsal pores begin between segments v./vi. if not earlier.

The clitellum commences in the hinder half of segment xiii., and
extends until the xxist segment ; only on the thirteenth segment is
it developed over the ventral as well as the dorsal and lateral surfaces;
in the remaining segments there is an area, occupying the whele of

682 MR. F. E. BEDDARD ON NEW [Dec. 20,

the space between the ventral pairs of sete, where there is no develop-
ment of the clitellum at all.

The sete are strictly paired and are all ventral in position; the
distance between the two ventral pairs is about half again as great as
that between a ventral and a lateral pair; there is no specialization
of the sete anywhere except upon the xviith, xviiith, and xixth
segments ; the ventral pairs of setee are absent from all of these
segments; on segments xvil. and xix. their place is taken by the
penial sete. I have already commented upon the apparently
universal absence of the ventral setze of segment xviii. in the genus
Benhamia.

Between segments viii./ix. and ix./x. there is a single oval papilla
lying in a position which corresponds to the interval between the
two ventral pairs of sete.

The oviducal pores lie in front of the cuter of the two ventral
sete on each side.

The alimentary canal has two gizzards ; there are the usual three
pairs of calciferous glands in segments xv., xvi., xvii. ; that section of
the cesophagus from which they arise is of a very narrow calibre ; but
from the xviiith segment the alimentary canal widens out very greatly
and forms a dilated and thin-walled region without any typhlosole,
which should perhaps be reckoned as belonging to the cesophagus.
The intestine proper begins in segment xxii.; the buccal cavity is
remarkable for the fact that it has a short cecum on the dorsal
surface, which differs from the rest of the buccal cavity in the
character of its lining epithelium; the cells which constitute the
innermost layer of this czecum are like those of the epidermic layer;
the cells are of two kinds, there being among them cells with clear
contents and not staining deeply with borax carmine, which are
exceedingly like the gland-cells of the integument. I comment later
upon the similarity which this worm shows in the said particular
to a representative of a totally distinct genus (Microdrilus ex fam.
Cryptodrilide).

The nephridia in the posterior part of the body, that is to
say behind the clitellum, are enveloped in a thick mass of vesicular
cells, a condition which is very common among tropical Earth-
worms; the nephridia are of course “ diffuse,” and there is a mucous
gland.

The reproductive organs show one peculiarity not common among
Earthworms—the terminal part of the vas deferens is ensheathed in
a muscular coat of some thickness ; it is only from the xvith segment
to the opening of the tube that this muscular coat is to be seen; the
penial setz are wavy at the extremity, being bent into a spiral with
not very close coils; on the last bit of the seta are a very few
denticulations with their apices directed forwards.

From Lagos I have also received examples of what I believe to be
Michaelsen’s Benhamia bolavi ; this same species has also turned up
from Dominica, Trinidad, Jamaica, St. Vincent, and, more remark-
ably still, from Seebpore, near Calcutta. I cannot distinguish
any of these individuals from Benhamia bolavi as described by

1892.] SPECIES OF EARTHWORMS. 683

Michaelsen’. All of my specimens are excessively small, not
measuring much more than an inch in length; this is about
the size given by Michaelsen. They all have the single median
oviducal pore, which not only distinguishes the species from the one
just defined, but also from every other Benhamia except B. gracilis.
This pore lies between the ventral sete of segment xiv. I found the
extent of the clitellum to vary somewhat ; Michaelsen gives segments
xili.-xx. This was the case with the worms from Jamaica and with
the single specimen from Seebpore ; in the individual from Dominica
the clitellum extended as far as the xxist segment, commencing with
the xiiith ; in the specimen from Lagos, on the other hand, the clitel-
lum was less extensive, viz. Xiv.—xviii.

II. Family Cryproprinip2.

9. Microdrilus saliens (sp. et gen. nov.).

I have had about a dozen specimens of this small Earthworm for
examination; they were picked out from earth that arrived at
Kew Gardens from Singapore ; another individual turned up from
Java and others from Penang. The small size of the species
suggested the generic name; the largest individuals are in alcohol
hardly more than an inch in length. During life the species is, like
Pericheta, remarkable for its extreme agility ; when touched they
twist themselves violently from side to side and can often spring for
a short distance above the table. The worms were preserved in
corrosive sublimate and acetic acid, followed by increasing strengths
of alcohol, and were investigated by transverse and longitudinal
sections. The genus belongs to the family Cryptodrilide as defined
by myself*. Though I have examined a considerable number of
individuals, the presence of sand in the intestines spoilt a good
many of the sections; hence my account of the anatomy of what is
in all probability a new genus in less than it should be. As, how-
ever, the worm shows one feature of some little interest, I have
thought it worth while to add to the present paper such notes as I
am able to give.

There are two gizzards, which follow each other almost immediately
and are only separated by the slightest constriction. In segments
XV., Xvi., and xvii. lie the calciferous glands; these have the usual
structure and contain large rhomboidal crystals. Their connexion
with the cesophagus is interesting; each pouch does not, as is
generally the case, open into the gut; there is only one duct on
each side communicating with the cesophagus. It lies just behind
the septum separating segments xv./xvi.; the two remaining pouches
of each side communicate with the middle pouch, which alone has

wiss. Anst., Bd. viii.

Soc. Edinb. 1890, i. p. 236.

684 MR. F, E. BEDDARD ON NEW [Dec. 20,

an opening into the gut. This arrangement, however, occurs in
Lumbricus, where it was first, I believe, accurately described by
Messrs. Marshall and Hurst in their ‘ Practical Zoology’; but it
has not been described in any other genera, and most certainly does
not exist in many Earthworms, e.g. Pontoscolex (= Urocheta),
where each gland opens by its own duct into the cesophagus. The
calciferous gland of the xvth segment has a rather smaller develop-
ment of the internal folds; the duct leading to the cesophagus is
ciliated. The intestine begins in the xviiith segment.

Another feature of interest in this genus concerns the male efferent
apparatus, which differs in detail from that of many other Earth-
worms ; the male pores are upon segment xvii. within the ventral
pair of sete; each aperture is really double, though this point is not
recognizable without having recourse to section-cutting. The two
apertures of each side are enclosed by the swollen epidermis, of which
the cells are very elongated and at the same time narrow; one
aperture lies in front of the other; the anterior of the two is
connected with the atrium, and through it project a few penial setz
which are enclosed in a muscular sac; these penial setz have the
form illustrated in Plate XLVI. fig. 13. The atrium is not in any way
remarkable; it belongs to the tubular type and is divided, as in
Acanthodrilus, &c., into a granular and a muscular portion. The vas
deferens near to its external opening, in fact from segment xv.
onwards, is enveloped by a thick muscular coat which is fully as
thick as is that of the atrium. I have already described in Pyg-
meéodrilus a similar muscular investment of the terminal region of
the sperm-duct ; and I have met with the same thing in two species
of Benhamia described above.

The nephridia of this worm are diffuse. The position of the
male pores distinguishes the genus from Digaster, in which the male
pores are upon segment xviii. On the other hand, it is quite possible
that it is congeneric with Dichogaster as extended by Michaelsen to
include his new species D. minus and D. hupferi. The particular
points referred to in the above description are not mentioned by
Michaelsen ; accordingly it is uncertain how far I am justified in
creating a new genus.

III. Genus Perionyx.

This genus was founded by Perrier’ for a worm closely related to
Pericheta, but differing from that genus by ‘‘the development of
the clitellum, the arrangement of the male orifices, the position of
the spermatothece, and finally the clearness of the segmental
organs.” Although the investigations of Pericheta which have
been carried out since Perrier’s paper was published have led to a
necessary alteration of the wording of the above quoted phrase, there
is every reason to agree with Perrier in holding the genus Perionyzx
as distinct from Pericheta. There is at present no reason for

1 “Recherches pour servir 4 lhistoire des Lombriciens, &c.,” Nouv. Arch,
du Muséum, t. viii. p. 126.

1892. ] SPECIES OF EARTHWORMS. 685

uniting, as Perrier thought might be eventually necessary, the two
genera Perionyw and Pericheta. Vaillant in thus uniting these
genera errs, in my opinion, as much on the one side as does
Benham’ on the other, when he relegates the two to different
families.

I have recently studied four species of Pertonye—one of which I
referred to some years since in connexion with the remarkable
variations in structure exhibited by individuals ; the second species, of
which I owe examples to the kindness of Dr. Michaelsen, has been
lately described by that naturalist* as Perzonya gruenewaldi. The
specimens of the two remaining species were sent to me some time
since by the kindness of Dr. King; they are from Seebpore. Putting
together what we know from Perrier’s investigations, from my own **,
from those of Michaelsen*, Rosa °, and Bourne’, and what I have to
say here with regard to this genus, we may thus define it :—

Genus Perionyx, Perrier.
Perionyx, E. Perrier, Nouv. Arch. Mus. t. viii. p. 126.

Sete forming complete circles, present as such upon all the
segments of the clitellum; male pores close together upon a depressed
area on segment xviii., with a group of modified sete in some species
near to each orifice; atria lobate ; spermatothece two (or three)
pairs in (vit.) viii. i., with or without diverticula; nephridia
paired ; no specially thickened septa; no ceca.

The above definition of the genus may now be supplemented by a
few remarks. These remarks will chiefly concern the species of the
genus ; the type species, P. ewcavatus, has been described by Rosa
as well as by Perrier, and to a more limited extent by myself. But
I am not quite certain, after comparing two out of the three species
described here in addition to Michaelsen’s P. gruenewaldi, as to
which of them is really Perrier’s P. ewcavatus.

The worms from Manila agree very closely with Michaelsen’s
P. gruenewaldi. Michaelsen distinguishes his species from that of
Perrier on the following grounds :—The pigmentation is so marked
that, if P. excavatus were of the same dark violet colour above,
Perrier would hardly have omitted to notice the fact: secondly, the
penial set of P. gruenewaldi appear to distinguish it from P.
excavatus: thirdly, the position of the gizzard; this organ is fixed
by Perrier in the twelfth segment ; Michaelsen, on the other hand,

686 MR. F. E. BEDDARD ON NEW [Dec. 20,

finds that in his species the gizzard is a mere rudiment in the four-
teenth segment, in front of which (in segment xiii.) are a pair of
calciferous glands not refered to by Perrier.

In all these points, with one exception, my “ Perionya excavatus”
agrees with Michaelsen’s species; I can distinguish no marked
difference of any kind between these worms, except in size, and the
size is after all not so marked as to lead to the opinion that it is an
index of specific distinction—110 mm. as compared to 85 mm. In
the more detailed description which follows of the male pores there
may indeed appear to be a little difference, but I am uncertain how
far to refer this to defective preservation of the P. gruenewaldi. The
exception to which I have referred concerns the gizzard; this organ
in the worms examined by myself and referred to Perrier’s P. ez-
cavatus is rudimentary indeed, but such as it is it appears to lie in
the sixth segment, as it does in the two other species to be described
presently.

Rosa gives some account of a worm from Burmah' which he
identifies with Perionyx excavatus of Perrier; he points out that
the gizzard is situated anteriorly, and not, as Perrier stated, in the
xiith segment ; Rosa, however, makes no mention of the calciferous
glands, nor of the genital sete. The description of the male pores
agrees with Perrier’s description and with the appearance of these
pores in the worms which I am disposed to identify with Perrier’s
Periony« excavatus. A very characteristic feature of the latter was
the absence of any diverticulum of the spermatotheca; with regard
to Perionyx excavatus Perrier remarks (Joc. cit. p. 129), ‘les poches
copulatrices sont situées dans les anneaux sept et huit; elles m’ont
paru formées d’un simple sac piriforme.” I take it that this
sentence implies the absence of any diverticula. On the other
hand, Michaelsen refers to diverticula in his Perionya gruenewaldi
and P. sansibaricus. This seems, at any rate, to be a good distinction
between the two species.

I have received from Seebpore examples of a species of Perionyx
which appears to be different from Perionyx excavatus ; it is certainly
different from the worms identified as such by myself ; but as Perrier’s
account is incomplete in one or two points, it is a little difficult to
be absolutely certain. These examples were rather stouter in build
than the Manila worms, and the coloration was a little less marked ;
this, however, may be the effect of the corrosive sublimate used in
the preparation of them. In the internal anatomy this species is to
be distinguished by five differences from the Manila species ; these
are as follows .—

The gizzard is fairly well marked and lies in the vith segment ;
there are no calciferous glands at all, though the cesophagus is
somewhat folded and vascular posteriorly. The last pair of hearts
he in the xiiith segment; in the form from Manila the twelfth
segment is the last which contains a pair of hearts; nothing is said
upon this point by either Perrier or Rosa. The spermatothece are,
as in the other species (excepting P. sansibaricus), two pairs and they

* Loe. eit.

1892.] SPECIES OF EARTHWORMS. 687

occupy the same segments, but each has a small irregularly shaped
diverticulum sessile upon the duct of the spermatotheca. Finally,
the atria are much larger than they are described in Perionyx
excavatus or than they are in the species which I here identify with
Perrier’s Perionyx exeavatus ; they are much broken up into lobes
and extend through three segments; the duct, too, is longer and
is contorted ; these glands in fact resemble very closely those of a
typical Pericheta.

Some years ago I briefly described a species of Perionyx from
Akyab* to which I gave the name of Perionyx macintoshii; this
species is admitted by Vaillant*, but not very heartily allowed by
Rosa’.

I have got two individuals of a large Perionyx which I believe
are referable to the same species; if so it is certainly a “* good
species.”

My observations upon Perionyx macintoshii were made upon a
single, not sexually mature, example; they were therefore not quite
conclusive as to the distinctness of the species, though the large size
alone is, as it proves, a sufficient index of the species, when com-
pared with the three others described here.

The internal anatomy is more like that of the first species from
Seebpore, which I propose to term Pertonyx intermedius ; the last
pair of commissural vessels are in the xtiith segment; the atria,
however, are limited to a single segment, and the spermatothecze
have no appendix. The principal differences concern the external
characters ; this species has a more extensive clitellum, it reaches
from the xilith to the xixth segment, being thus longer by two
segments than in the other species; the male pores bave not, as I
pointed out in my earlier description of the species, the characteristic
appearance of those of Perionyx excavatus; they are placed in a
ventral area, but the two pores are uot upon separate papille. The
four species of Perionyx referred to in this paper show certain very
characteristic differences in the condition of the male pores and of
the setz in their immediate neighbourhood, of which the following
is an account.

In Perionyx gruenewaldi the area upon which the atrial pores are
borne is not, owing to the small size of the worm, very well marked
when looked at through a lens. When this part of the body is
submitted to a microscopic examination, the area is seen to be
bounded by an obvious groove. ‘The ordinary setze of this segment
(the xviith) do not extend on to this area except on one side of the
body, where a single seta is inserted on to the outer edge of the area;
as, however, a groove cuts off the tract of integument which bears
this seta from the genital area, it might be held that the line between
the genital area and the surrounding integument was indicated by
this groove. There are four genital setze on each side which, although

close together, are really in a line which is in the same direction as
the circle of setee of the segment; there is, however, a gap between
the last seta of the ring of unmodified sete and the first of the
genital setee. The atrial pores are just in front and to the outside
of the groups of the genital setee. The setze themselves have been
figured by Michaelsen.

In Perionyx excavatus the male genital apertures are each
placed upon a semicircular elevation, the two being in close contact.
These flat papille are both depressed below the surface of the
surrounding integument; this depressed area appears to be only
sharply marked off anteriorly and posteriorly by grooves ; laterally
there is no sharp demarcation, the papille gradually rising until
they attain the level of the surrounding integument. Each papilla
has 5 or 6 genital sete of a precisely similar appearance to those of
Perionyx gruenewaldi just described ; they are arranged in the same
way, being continuous with the line of sete of the segment and
are separated from them by a space. These genital sete are also
longer than the ordinary sete of the body, but the latter show a
certain amount of ornamentation, which was specially marked in the
case of the ventral set of segment xix.

In Periony« macintoshii the ventral area which bears the atrial pores
forms a sucker-like structure completely sunk below the level of the
surrounding epidermis ; it measured in one individual 3 mm. across.
This difference from the other two species may possibly be correlated
with the fact that in Perionyx gigas the clitellum extends beyond
the male apertures.

In Perionyx intermedius the arrangement is rather different from
that which obtains in the two species just described. The xviiith
segment is widened in the middle ventral line; the integument
has a tumid swollen appearance, and there is a transverse groove
into which open the atrial pores. The row of setz of this segment
are not continued over the median area, but in one specimen I
observed two sete, one on each side at the bottom of the groove
already referred to. As the extremities of these were unfortunately
broken off Iam not able to say whether they showed any more
marked ornamentation than the other sete of the body ; in any
case they were not different in form.

It will be seen from the above details that the genus, as we at
present know it, falls into two subdivisions. In Perionyx macin-
toshii and P. intermedius there are no specially modified sete in the
neigubourhocd of the male pores, and the latter are placed upon a
median area which is not divided by a cross furrow into two areas,
one for each pore.

In Perionyw ewcavatus and P. gruenewaldi there is a group of
specially modified setze near to each male pore, and these pores are
placed each upon a separate papilla, both papille being enclosed
within an area marked off from the surrounding integument.

It appears to me that in this genus we have an early stage in the
evolution of the penial sete of other types—e.g., the genus Mega-
scolex ; if the modified sete of Perionyx excavatus were withdrawn

1892.] SPECIES OF EARTHWORMS. 689

from the exterior of the body and lodged in a sac formed by their
withdrawal, we should have the sac of penial sete such as occurs in
so many Earthworms. Perionyx macintoshii is in an earlier stage still ;
the setz in the neighbourhood of the male pores are not modified,
but appear to resemble those of other segments. Finally the four
species may be thus briefly defined. (I have not included Bourne’s
Perionyx saltans pending further details, or Michaelsen’s P. sansi-
baricus, which seems to resemble it in the alternation of the nephridia
and may be identical.)

IV. Genus MoniuicAster.

13. Moniligaster bahamensis.

This genus and the closely allied Desmogaster of Rosa have been
hitherto only discovered in the tropics of the Old World; India,
Burma, Japan, and the islands of Luzon, Ceylon, and Sumatra have
yielded all the known species. In the present paper I describe a
form which I received alive together with a number of other species
from Kew, whither it had been imported accidentally with plants
from the Bahamas.

The worm is small and slender, measuring about 25 mm. in length.
Although this interesting genus has been now so frequently studied,
there yet remain a few points upon which further information is
desirable : some of the hitherto missing information I am able to
supply in the present paper. The genus is chiefly interesting on
account of the fact that it upsets in so many points the old distinc-
tion between ‘ Terricole ” and “ Limicole.” Though terrestrial in
habit and in general appearance the anatomical structure is in many
respects that of certain aquatic Oligocheeta. Our present information
upon the genus is derived from the following memoirs :—

papers containing new facts with reference to the genus; other
papers which refer to it will be quoted in their place in the course
of the following pages.

External Characters.

In the present species, which I name Moniligaster bahamensis,
the clitellum was fortunately developed ; it was not, however, visible
until the worm was examined by means of sections, and was then
found to occupy four segments, viz. x.-xiii. It will be remem-
bered that Perrier created a special group, the Aelitelliens, for
Moniligaster, since it appeared to possess no clitellum; the anterior
segments were, however, described as resembling in certain particu-
lars the clitellum of other worms and as probably representing that
organ ; but it is not necessary to remark that frequently the anterior
segments of Earthworms, especially of the smaller species, are con-
siderably thicker, and also appear more opaque owing to the
enclosed viscera. The first to describe the clitellum was Prof.
Bourne ; he wrote that it occupied segments x.—xiii.; but there
are no details given as to whether the clitellum was visible without
first having recourse to section-cutting ; it certainly is not in the
present species. The clitellum begins and ends sharp at the margins
of the segments which it occupies. The resemblance which the
forward position of the clitellum in Moniligaster gives this genus
to the Lumbriculidee need not be again emphasized ; I have already
sufficiently dwelt upon the matter.

Ihave, however, now to refer to an interesting point with regard
to the clitellum which has not yet been described: the minute
structure of the clitellum differs from that of all other Earthworms
and agrees with that of all ‘“ Water-worms” in being composed
of a single layer of cells only. This appears to me to be a point
of great importance ; coupled with the position of the clitellum it
gets even greater importance than it would otherwise have. Rosa
has sought to minimize the significance of the anterior position of
the clitellum ; but I do not think that anyone will deny that the
resemblance in structure which it shows to the lower Oligocheta
cannot be explained away ; there is, moreover, no resemblance in

692 MR. F. E, BEDDARD ON NEW [Dec. 20,

habit which might perhaps discount the value of the characters
afforded by the clitellar epithelium. Although the clitellar epithe-
lium is only one cell thick, it is made up of cells of two kinds:
there are large non-staining cells, imbedded among smaller cells loaded
with darkly staining granules. Plate XLV. fig. 5 illustrates the
structure of the clitellum, which, as will be seen, is not very much
thicker than the epidermic tissue of adjacent segments not nodified.

The setze, as in other species, are strictly paired; I could find no
setee upon the second segment of the body: I have already men-
tioned that in MW. barweili these setee are very small and easy to be
overlooked ; I could not find the least trace of them in the present
species.

The muscular layers of the body-wall are remarkable in certain
points. The circular layer, as is shown in fig. 5, does not extend quite
up to the longitudinal layer: between the two is a space occupied by
a delicate connective tissue with interspersed nuclei; in this layer
run the nerves, of which there are three main trunks in each seg-
ment. The muscle-fibres, when seen in transverse section, show the
characteristic appearance of the muscular fibres of the Leech in a
more distinct way than I have ever noticed in any Oligochetous
worm: the layer of muscular substance in each fibre is very narrow
as compared to the central cavity, which is filled by a faintly granu-
lar matter; this is not stained ; the fibres differ greatly in diameter,
the smaller ones being nearest to the epidermis. One might
perhaps speak of the layer which lies between the circular and
longitudinal muscles as a “‘ nervous layer”? ; it contains many small
nerve-twigs besides the main trunks already referred to. The
longitudinal muscular layer is, comparatively speaking, narrow ; its
fibres tend to be arranged in the bipinnate fashion which is so com-
mon, though not universal, among the higher Oligocheta. Here
also it was easy to see that each fibre has a central soft core. On
the whole the structure of the body-wall of the Annelid, with the
exception of course of the clitellum, is like that of Earthworms
rather than the aquatic genera; but Phreoryctes, which Claparéde
ranged among his “ Limicolz,’’ has a body-wall which is also like
that of the higher Oligocheta ; so that this point of resemblance
is not conclusive as to the affinities of Moniligaster.

Internal Anatomy.

The internal structure of this new species of Moniligaster is not
widely different from that of Moniligaster barwelli; there are four
thickened septa which divide segments v./ix. Probably the exis-
tence of this number of septa is a character of generic importance,
as they seem to occur in M. beddardi as well as in the two species
referred to. The alimentary canal, again, presents no differences
from that of other species ; there are no calciferous glands, and there
appears to be no vascular tract of the cesophagus which in so many
Oligocheeta: replaces functionally these glands; the usual three
gizzards are present, commencing in the xilith segment. The
nephridia have a large cecum as in other species; I observed the

1892. ] SPECIES OF EARTHWORMS. 693

funnel of the nephridia, which lies in the segment in front of that
which contains the rest of the nephridia. The structure of the
nephridia is not that of the aquatic Oligochzeta; they recall those of
the Geoscolecidx. It is of course the reproductive organs which are
so different from those of the higher Oligocheta.

The testes, as in the other species of the genus, are placed within
the sperm-sacs attached to the front wall of segment x.; they are
also in contact with the ciliated rosettes, which open likewise into
the interior of the sperm-sacs. In Moniligaster barwelli 1 figured
and described the ciliated rosettes as lying in the same segment as
that upon which the atria open on to the exterior; this-is also the
ease with I. beddardi and with the species described in the
present paper; in those two Moniligasters the sperm-duct is very
short and hes entirely within the xth segment. In M. bahamensis
the sperm-ducts are remarkably long and much convoluted, re-
calling the sperm-ducts of such genera as Pachydrilus; they do
not lie entirely within the xth segment but extend forwards into
the segment in front. It is quite possible that the difference
is merely one of maturity in the various individuals. The
arrangement of the sperm-ducts is, curiously, the reverse of the
arrangement characteristic of the posterior sperm-duct of the
Lumbriculide ; in these worms the sperm-ducts in question traverse
the septum lying behind the male pore, and then bend back to
traverse the same septum again. This is exactly what occurs in
Moniligaster bahamensis, only that it is the segment in front of that
which bears the male pores which is twice perforated by the sperm-
ducts. I do not, of course, intend a serious comparison between the
two forms in this matter; but at any rate the disposition of the
sperm-ducts in Moniligaster is exceedingly different from anything
that occurs in the remaining genera of Karthworms.

The sperm-sacs in the present species are restricted to the xth
segment; this was the case at any rate with one of the two species
which I studied by means of longitudinal sections; the segment in
which they lie is the xth; as in the other species of the genus,
their cavity is undivided by trabecule, but filled with developing
sperm.

The orifices between segments x./xi. lead into a pair of muscular
sacs; each sac has a narrow lumen bordered by a single layer of
low columnar cells covered with a moderately thick chitinous layer ;
outside the epithelium is a mass of muscles which are somewhat
loosely arranged, and in the interstices of which lie groups of glan-
dular cells. The sac is oval in form and at the distal end the lining
epithelium is reflected back over a conical process which contains
the duct of the atrium proper ; the terminal sac with this evidently
protrusible structure has clearly the closest possible resemblance to
the penis and penis-sheath of the Tubificide. Vejdovsky has
figured’ a protrusible penis in the Lumbriculid Stylodrilus—a family
which is in some respects nearer to Moniligaster than are the
Tubificide. Among Earthworms the nearest approach to the penis

‘ System, u. Morph, Oligochaeten, pl, xi, figs, 11-16,

694 MR. F. E. BEDDARD ON NEW [Dec. 20,

of the aquatic Oligocheta and of Montligaster is to be seen in the
genus Eudrilus. But Moniligaster obviously comes much closer to
the aquatic Oligochata than does Hudrilus in this particular.

Communicating with this muscular penis is the atrium. I have
already described and figured the structure of the atrium in Monili-
gaster barwelli, and have pointed out its close similarity to the
atrium of the Lumbriculide; the Tubificid Branchiura has an
atrium which is also constructed upon the same plan. In Monil-
gaster bahamensis we have the same low and darkly staining
columnar epithelium lining the lumen; this is surrounded also by
the same comparatively thick circular muscular layer; in M. baha-—
mensis, as in M. barwelli, the outermost covering of the atrium is
formed by oval groups of pear-shaped cells. I find, however, that
in the species of Moniligaster with which the present paper deals,
the ducts of these cells, which are simply filiform prolongations of
their substance, pierce the muscular layer in bundles and evidently
pour their secretion into the lumen of the atrium. These ducts
were exceedingly conspicuous owing to their dark staining, an effect
possibly due to the presence of abundant secreted granules. They
were probably overlooked in Moniligaster barwelli, owing to their
not being stained. I could find no peritoneal layer even of the
thinnest round the atrium.

Rosa has described a somewhat different structure for the
“prostates ” (atria) of Desmogaster. He has above all insisted upon
the presence of a peritoneal layer investing the organ superficially.
The minute structure is described in the following words :—
“T] lume interno é piccolissimo, appena 5 del diametro; esso é
tappezzato da un epitelid cilindrico. Hsternamente a questo la
massa delle pareti é prevalentemente muscolare; nella parte pid
centrale le fibre sono annulari; in tutto il resto sono longitudinali,
disposte in fasci raggianti. Nella regione piu esterna questi fasci
divergendo racchiudono fra di loro delle ghiandole pluricellulari
piriformi che per lunghi condotti vanno a raggiungere il lume
interno, ma queste ghiandole non arrivano alla parete esterna deila
prostata perche i fasci muscolari, benche ridotti a sottili strischie,
passano fra una ghiandola e | alta e si ricongiungono fra loro, formando
spesso solo un sottile rivestimento attorno alla base diesse. HE inoltre
ben evidente un rivestimento esterno peritoneale che spesso nelle
sezioni si vede staccato. La superficie delle prostate non e racemosa
como nei Moniligaster, wa liscia 0 appena ondulata, ed ha lo stesso
aspetto sericeo delle prostate degli Hudrilus.’ ‘This description and
the illustrative figure are suggestive rather of the penis than the
atrium of Moniligaster, particularly with regard to the gland-cells
imbedded among the muscles. It appears to me to be possible that
Desmogaster differs from Moniligaster in that the atrium is not
specialized into two regions.

The ovaries are in the xith segment, attached to the front wall
of that segment, as is so usual; the oviducal funnels open opposite
to them and appear to be particularly large; but the most remark-
able feature of the female reproductive organs of this Annelid are

1892.] SPECIES OF EARTHWORMS. 695

the large egg-sacs. Even Rosa, who is so anxious to minimize the
affinities of the Moniligastride to the lower Oligocheta, admits
that the size of the eggs-sacs is unknown in the Terricole, though
it is, he remarked, going rather too far to exclude Moniligaster
from the Terricolz on these grounds. In Moniligaster beddardi no
egg-sacs were found by Rosa; but I do not think that this failure
to find the structure in question is tantamount to a proof that they
are non-existent in that species, as Rosa seems to imply. Anyhow
they are large in the present species, and occupy at least three
segments. Bourne, the first to discover these bodies, stated that
they occupy in Monilgaster minutus segments xil.-xy. As to the
ova of Moniligaster, Bourne says nothing about them save that
there ave ova in these sacs; the eggs in Moniligaster beddardi are,
according to Rosa, very minute. In the species here under consider-
ation the ova present a very remarkable character, unique among
Earthworms: they are not particularly large, though, perhaps,
larger than in many Earthworms; the remarkable fact about them
is that they are crowded with yolk-particles: to so great an extent
is the yolk developed that the nucleus is by no means always
apparent ; the yolk-particles are moreover, as is shown in the accom-
panying figure (Plate XLV. fig. 1), of considerable size, quite as
large as they are in eggs of a much greater size. This fact about
the ova of Moniligaster bahamensis is of considerable interest. I
pointed out some time since* that the only distinguishing characters
between the Megadrili and the Microdrili of Benham ®, not alluded
to by Benhain himself, are the three following :—

(1) Large size of ova.
(2) Clitellum consisting of only a single layer of cells.
(3) Sexual maturity at a fixed period.

In the three points mentioned the Microdrili(= Limicole of
Claparéde minus Naids and Holosoma) differ from all the Megadrili or
Earthworms. Now I have just pointed out that the ova of Monili-
gaster, although not so large as they are in the Microdrili, agree
with them in having a great quantity of yolk, a character not found
in any other Earthworm ; this is, at any rate, an indication of a step
in the direction of the Microdrili, even if it be not held to bea
point of close affinity with them. On a previous page I have pointed
out that the structure of the clitellum is quite like that of the lower
Oligochzta in being made up of asingle layer of epithelium only ; it
may be added that in all possibility the sexual maturity is at a fixed
period ; this would account for the failure of so many investigators
to find the clitellum; Prof. Bourne tells me that he expects that
the clitellum will be found at the proper season in all Moniligasters.

It is difficult therefore to see on what grounds Moniligaster is to
be referred to the Earthworms as opposed to various groups of the
ayuatic Oligocheta. Rosa justly points out that Yetragonurus

2 « An Attempt to Classify Harthworms,” Q. J. M. 8. vol, xxi.

696 MR. F. E. BEDDARD ON NEW [Dec. 20,

probably, and Adlurus certainly, have the male pores situated very
far forwards, nearly as far forwards as in Moniligaster ; this he
holds renders it unnecessary to lay any particular stress upon the
forward position of the pores in question, in Moniligaster, as an
indication of affinity with the lower Oligocheta. Granting this
for the moment, it seems a little unfair that Rosa should use precisely
the same character as an indication of affinity with the Lumbricide,
especially with the two genera just mentioned. On p. 386 of his
memoir, however, he states, as a feature of resemblance between
Moniligaster and these genera, the fact that in both the male pores
are in front of the oviducai pores.

As to the forward position of the clitellum in Moniligaster, Rosa
quotes the instance of Buchholzia appendiculata, where the organs
of the body are two segments in front of the usual position which
they oceupy in allied species. I do not think from what we now
know that it will prove to be the case that in any species of Monili-
gaster the clitellum is so far back as segments xii.—xv., a position
which, as Rosa justly points out, is after all not so very different
from what we find in other undoubted Earthworms. The new facts
contained in the present paper do not furnish any material for a
renewed discussion as to what group of Earthworms comes nearest
to the Moniligastridze: the only pronounced feature in which they
resemble any Earthworms is the presence of several gizzards lying
at the end of the esophagus; but we now know that this character
is found in several genera belonging to at auy rate three families,
viz., Pleionogaster, Bilimba, and the three Eudrilids Hyperiodrilus,
Heliodrilus, and Libyodrilus. This character, therefore, must be
neglected as a mark of affinity.

V. Family Evprivipz.

14, Eudriloides durbanensis.

The division of the Eudrilide into genera requires some further
consideration ; we are at present but imperfectly acquainted with a
large proportion of the many forms recently described from tropical
Africa by Dr. Michaelsen ; and as there are doubtless a large number
of forms awaiting discovery, it is also premature to attempt any
systematic revision of the family. I therefore refer provisionally the
species, which I describe in the present paper, to the genus Ludri-
lotdes, without pretending that it may not ultimately be transferred to
some other genus; I give at the end of the description my reasons
for this course.

The worms which I describe here were obtained from Kew
Gardens ; they had reached those gardens from Durban, Natal; I
preserved them in alcohol after killing them in weak spirit. There
were five specimens, of which two were studied by longitudinal
sections, the others examined in glycerine. The species is a small
one; the length is about two inches by a breadth of not more than
two millimetres ; the worms are therefore long and slender. During
life the colour was red—a colour owing, of course, to the absence of

1892. | SPECIES OF EARTHWORMS. 697

integumental pigment and to the consequent visibility of the blood-
vessels through the skin.

The setz are strictly paired. The clitellum is not developed
ventrally, it extends dorsally over four segments, viz. xiv.—xvii; the
male pore is single and median upon segment xvii. near to the poste-
rior end of that segment; the spermatothecal orifice is also single
and upon the xiiith segment.

There are a few papille present; on the eleventh segment are a
pair on each side of the median ventral line; on the fifteenth seg-
ment are another pair occupying a corresponding position ; finally
there are two pairs on segment xiii., one pair in front of and one
behind the spermatothecal orifice ; in sections these papill are seen
to be slight depressions of the integument, and the epithelium is
deeper than that which covers the body generally ; it is also composed
of large clear cells which have a glandular appearance. It is pos-
sible that the papille are adhesive disks, and not, as they seem
frequently to be in some other Oligochzta, sense-organs.

A very marked peculiarity of the family Eudrilidz is the presence
in the skin of those peculiar sense-bodies which were first described
by myself in Eudrilus, and have since been found in a few other genera
of the family ; they are, however, by no means universal, but have
never been met with in any worm not belonging tothe family Eudrilide:
they occur in the species under consideration. I only observed then:
in the clitellar region; this was perhaps due to the fact that else-
where they were not so readily visible owing to the thinness of the
epidermic layer ; they lie in the clitellum beneath the epidermis,
and are placed longitudinally with reference to the long axis of the
body.

The muscular layers are not very thick; but there are no note-
worthy points to comment upon.

With regard to the internal anatomy, the alimentary tract shows
a peculiarity not hitherto described in any Eudrilid: in many
genera of this family there are calciferous glands of two kinds—
paired organs in segment xiii., and ventral unpaired pouches in seg-
ments ix., x.,xi. The present species has neither of these two kinds
of appendages ; but it is not, as are many forms (e. g. Libyodrilus),
entirely without glands appended to the cesophagus.

In segments vi.—x. there are pairs of whitish-coloured glands which
have a remarkable structure, quite unusual and unparalleled in the
group Oligocheta (see, however, the following description of Tricho-
cheta barbadensis). One of these glands is illustrated in fig. 11 of
Plate XLVI.; the gland is of an oval or sometimes a more irregular
shape ; it is bounded externally by a thin layer which stains darkly
with borax carmine, and which is perhaps to be regarded as the
peritoneal layer investing the gland externally ; within this there
is a mass of tissue consisting of innumerable spherules like the yolk-
spherules of an ovum, and, like them, not stained by the reagent.
Here and there among the mass of spherules are scattered nuclei,
evident on account of their staining very deeply with the reagent
that produces no effect upon the surrounding granules ; there were

698 MR. F. E. BEDDARD ON NEW [Dec. 20,

no cell-outlines visible, but nevertheless I cannot but regard the
mass as being composed of cells with perhaps very thin boundary
lines. In the centre of each of these glands was a darkly staining
rod of tissue which appears to be a blood-vessel ; at the apex these
glands opened into the lumen of the cesophagus by an exceedingly
natrow diverticulum of the cesophagus; this tube soon ends,
leaving the greater bulk of the calciferous gland composed of the
peculiar tissue that I have already described.

The only other Oligocheets in which calciferous glands at all com-
parable to these exist are the genera Gordiodrilus and Trichocheta.
I have lately * described the principal anatomical characters of the
former new genus, which is mainly found in tropical Africa, though
also extending its range to the New World. Inall the species of that
genus there is a single unpaired median pouch in the ninth segment
which in certain particulars resembles the calciferous glands of
Eudriloides durbanensis ; the resemblance consists in the tissue which
builds up the greater part of the gland and which is apparently
identical with that which builds up a greater proportion of the glands
in Eudriloides. The peculiar kind of tissue which characterizes
the calciferous glands of these two genera of Oligocheta is, however,
not unknown in the group; in several aquatic Oligocheta, for
example in some Naids and in many Lumbriculide such as Sutroa’,
the nephridium, just after traversing the septum, is swollen out into
an oval tract which shows precisely the same structure as that of
the glands already described. I have figured this tissue in the
American Lumbriculid Suéroa, and suggested that it might possibly
serve as a filtering tissue. The oval swelling is permeated by fine
canaliculi which are not always apparent; in the same way the
similar tissue in the calciferous glands of Eudriloides and of Gordio-
drilus seems to be traversed by fine canaliculi (shown in the case
of Gordiodrilus in fig. 8 of plate vii. of my memoir already quoted
dealing with the anatomy of that worm). It is quite possible,
therefore, that Michaelsen’s notion that these glands serve as organs
of assimilation, rather than as organs of secretion, may prove to be
correct in the two Annelids which possess this peculiar form of
calciferous gland ; although, as I have pointed out, there can be no
doubt that the ventral pouches of Hudrilus do not, at any rate,
entirely serve such a purpose, for I found particles of calcareous
secreted matter in the lumina of the said pouches; furthermore the
resemblance of this tissue to that found in the nephridia is worthy of
note in relation to the fact that in Gordiodrilus there appears to be a
communication between the ventral pouches and the nephridia. I
do not, however, wish to insist upon more than the actual structural
likeness between the tissue in the two series of organs ; this is
indeed very striking. It may be that this resemblance between the
calciferous pouches of Hudriloides and Gordiodrilus is some evidence

of their affinity ; Gordiodrilus is clearly a rather degencrate form,
with no marked affinities to any other genera except to Ocnero-
drilus and Pygmeodrilus—an affinity which may be merely due to
the fact that they are all degenerate forms, and thus not a real
affinity. In any case it is remarkable that this curious form of
glandular tissue should be limited to the calciferous glands of the
two genera Hudriloides and Gordiodrilus.

As regards the rest of the alimentary canal, there are not many
points which require notice ; there is a gizzard in the fifth segment,
well developed and by no means rudimentary.

The first septum lies just in front of the gizzard and thus separates
segments iv./v.; the four septa which follow the gizzard are thicker
than the rest. The nephridia are of course paired, and the first
pair appear to belong to the fourth segment.

There is only a single pair of testes, which lie in the xith segment,
attached to the front wall of that segment; opposite to them are
the funnels of the sperm-ducts, these are very large and much folded.
The sperm-duct has no swelling at its origin from the funnel; it is
a narrow tube, much narrower than the oviduct; it opens into the
atrium a little way before the opening of the latter into the terminal
copulatory apparatus. The atria are two closely applied tubes
contained within one sheath, so that on a dissection the atrium
would no doubt appear to be single. Whether the division of the
atrium is an indication of its beg the result of the fusion of two
separate atria is not obvious; at first sight it does appear to be
obvious, but it will be remembered that in Hudrilus each atrium
is similarly divided into two completely separated tubes within a
common sheath. This atrium consists entirely of a layer of gland-
ular cells ensheathed in a very thin peritoneal layer ; the terminal
apparatus is a muscular diverticulum of the body-wall, with which
are also connected a pair of sacs each containing a single penial seta,
whose shape I am unable to describe.

The spermatotheca is unpaired, it opens on to the exterior in
segment xiii. ; the aperture leads into a thick-walled sac from which
arises a thinner-walled sac extending backwards into the next
segment ; this latter is lined by cells which appear to be similar to
those found in the corresponding organ of other Eudrilide, and
suggest that in this species as in others the spermatotliecz are
developed from the ccelom, and are therefore not homologous with
the spermatothecee of other Earthworms. The terminal sac of the
spermatotheca is lined by an epithelium which has preserved the
characters of the epidermis whence it is derived; the cells are of
two kinds, the usual glandular and the interstitial cells.

To the spermatotheca on each side is attached a receptaculum
ovorum ; these sacs, although attached to the spermatotheca, are not
really connected with it, that is to say they do not open on to the
spermatotheca; the egg-sacs are not in any way unusual in their
structure, their cavity is divided up into numerous compartments by
trabecule. In the compartments are lodged the ova: the ova in
the egg-sacs are not accompanied by masses of developing ova or by

700 MR. F, E. BEDDARD ON NEW [Dec. 20,

cells serving as nutritive cells to the developing ova; the oviducts
are peculiar in that they perforate the septum dividing segments
xlii./xiv. ¢wice. The funnel opens freely into the interior of segment
xiii. right opposite the ovary and also into the interior of the egg-
sac; it then passes into the cavity of the thirteenth segment and
bending back runs straight along the body-wall up to its point of
opening on to the exterior, The oviduct has thus an unusually long
course, which is further increased by the fact that the pore is
situated near to the hinder end of the fourteenth segment; the
calibre of the oviduct is considerably greater than that of the sperm-
duct ; the two can be easily compared in this respect, as the sperm-
duct passes close to the oviduct ; the oviduct is not ensheathed in
a muscular coat; the ciliated epithelium is only covered by a delicate
peritoneal layer.

The ovaries lie in the thirteenth segment, attached, as is usual, to
the front wall of that segment. The septum dividing segments
xti./xiiil. joins that which follows, and a sac is thus formed which
encloses the ovaries and the terminal bulbus of the spermatotheca.
Centrally this sac is almost filled by the bulbus, but laterally there
is plenty of room, and the spacious cavity thus formed is oceupied
not only by the ovaries and detached ova, but also by an immense
quantity of small nucleated, often fusiform corpuscles; similar
corpuscles are also found in great abundance in the xith segment.
I am doubtful whether to regard these as slightly metamorphosed
cells of the ovary and testis respectively or merely as perivisceral
corpuscles, which happen to have been aggregated together in
greater numbers in the two segments referred to than elsewhere.

The ripe ova (from the egg-sac) have no striated membrane such
as is found in certain other Eudrilids.

This worm evidently belongs to one of the more simply organized
of the Eudrilide ; for the fusion of the female organs is incomplete.
It must therefore be referred to one of the following genera, viz.
Eudriloides, Platydrilus, Megacheta, Reithrodrilus, or Notykus.

As to external characters it agrees with Platydrilus in having a
saddle-shaped clitellum, and also in the extent of the clitellum.

The internal anatomy is in some respects unlike any of these
genera; for instance, the peculiar form of the calciferous glands
marks out the present species from all Eudrilide including those
mentioned, in none of which are there calciferous glands at all.

In possessing one pair of testes and in the corresponding single
funnels &c. the worm resembles Notykus, Eudriloides, Megacheta? ;
but this is not of course an important difference from Platydrilus &e.
The complete fusion of the two atriais peculiar to the worm, though
a commencing fusion occurs in Hudriloides, from which, however,
the species described here differs in the shortness of the atria and in
the absence of a muscular tunic. The principal reason which leads
me to refer the worm to the genus Hudriloides is the structure of
the female organs. 1 have described the modification of the septum
dividing segments xili./xiv., which forms a sac enclosing the terminal
part of the spermatothecal sac and the ovaries and oviducal funnels:

1892.] SPECIES OF EARTHWORMS. 701

though this seems to be perfectly similar to the arrangement
figured by Michaelsen* for Notykus emini, 1 am inclined to think
that in the latter there is a distinct sac independent of the septa.

VI. Family GroscoLecip&.
15. Trichocheta barbadensis, n. sp.

I have examined a single specimen of this species which I received
alive from Kew; it is a native of Barbadoes.

The worm was 24 mm. long and consisted of 84 segments; the
colour-during life was red, the skin containing no pigment.

The sete are paired, their shape is precisely that of Trichocheta
hesperidum, a new genus and species of Earthworms which I have
recently * described from the island of Jamaica. On the clitellum
the sete appeared to be rather larger than those upon the other
segments of the body, and the ornamentation at the tip a little more
pronounced. Although the sete in the present species show no
trace of the characteristic irregularity of Trichocheta hesperidum,
I do not hesitate to place them in the same genus on account of
the peculiar form of the sete, which is unmatched in any other
Oligochet. At first one would be inclined to regard the irregularity
of the setee as a mark of generic distinction; but it must be borne
in mind that in Pontoscolex, as was first pointed out by Fritz
Miller *, and I have been able to confirm his discovery, the set
are occasionally regular and paired.

The clitellum, exceptionally for the family Geoscolecide, is
complete; that is to say, there is no ventral tract free from
glandular tissue. Rosa has used the saddle-shaped clitellum as one
of the characters of the Geoscolecide ; the present species shows
that this character can be no longer used. The clitellum extends
from the xiiith segment to the xxiind.

The prostomium appeared, before the worm was examined by
means of sections, to resemble that of Rhinodrilus or Trichocheta
hesperidum, that is to say it lay apparently in the mouth instead of
projecting above it. In longitudinal section, however, this appear-
ance is seen to be largely due to the retraction of the prostomium,
which is perhaps facilitated by the division of the first segment
into two annuli by a groove.

The nephridia are paired, the first pair being rather larger than
those which follow: the large size of the first pair of nephridia is
commonly found to be a character of the Geoscolecide ; it is hardly
so pronounced in the present species as in Pontoscolex for example.
The duct of this nephridium is long and appears to open on to the
exterior on the third segment.

As to the vascular system, the only point that I particularly note
is the presence of a pair of large hearts in each of segments x., xl.

702 MR. F. E, BEDDARD ON NEW [Dec. 20,

Separate calciferous glands like those of Pontoscolex do not exist
in the present species, though it is very possible that three pairs of
cesophageal ceca, the structure of which will be described presently,
are the homologues of those glands. The calciferous glands are,
however, functionally represented, as is so generally the case with
Earthworms in which no separate czeca exist, by a tract of cesophagus
with much folded walls ; numerous crystals lying in the interstices
of the folds appear to be the product of their epithelium, and are
apparently similar to the crystals met with in true calciferous glands.
This tract of cesophagus extends through about three segments,
commencing with the tenth. It closely resembles the corresponding
structure in the nearly allied form Onychocheta’.

In segments Vii., vili., ix. are three pairs of very small cesophageal
ceeca; their calibre in transverse section is about the same as that
of the dorsal vessel, but as they are very short and narrower at
both extremities, they only possess eveu this small diameter for a
limited distance. Each cecum is lined by a layer of low cubical
epithelium which does not appear to be ciliated; between this
epithelium and the peritoneum is a plexus of blood-vessels which
are very large in proportion to the cxcum itself, and protrude into the
lumen, reducing it very greatly and causing it to assume here and
there a star-shaped contour. It will be noticed that these ceeca occupy
the same segments as do the calciferous glands of Pontoscolex, and
they may probably be safely regarded as the degenerate represen-
tatives of the latter.

The gizzard is large and extends apparently through a considerable
number of segments; defining its limits by the septum which
bounds it posteriorly, it would seem to lie in the sixth segment, but
the anterior septa are not sufficiently clear to permit of fixing its
anterior limits.

There are, as in some other Geoscolecidz, only a single pair of
testes. These belong to the xith segment, and are attached to the
front wall of that segment. They are, together with the funnel of
the vas deferens, enclosed in a sac, which extends back for some
segments (to about the xviith) and is the sperm-sac ; the sperm-sacs,
however, although the worm was fully mature, contained no sperm,
and were of a very narrow calibre as in Trichocheta hesperidum.

The funnel of the sperm-duct is very large and folded; the
funnel extends below the testes and nearly reaches the septum to
which the testis is attached ; the posterior limit of the funnel, still
of course enclosed within the sperm-sacs, is in the septum bounding
segments xiii./xiv.; but they lie close to the ovary. The sperm-
duct itself opens on to the exterior on or beyond the xviith segment ;
I only traced it as far as the latter, but did not observe the actual
opening. The ovaries are in xii. and opposite to them are the
funnels of the oviducts; the oviducal pores are just in the groove
between the xivth and xvthsegments. The spermatothecee are three
pairs of simple sacs like those of Pontoscolex inix., x., xi.; the last
pair open on to the boundary line of segments xi./xil.

16. Ilyogenia africana, nov. gen., n. sp.

Among the specimens of Eudriloides durbanensis was an example
of a totally different species—a fact which I only recognized after
examining longitudinal sections of the head end of the worm; the
smallness of size, absence of pigment, and similarity in the position
of the clitellum prevented me from distinguishing them when alive.
They belong, however, to totally different families; the species now
to be described is a Geoscolecid.

It has paired setee which show no recognizable ornamentation.
I did not observe whether those upon the clitellum were in any way
different from the rest.

The clitellum commences in the xiith segment and ends in the
xixth ; itis a little difficult to be precise about the actual beginning
and ending. If we reckon as clitellum only that tract of epidermis
where the “untere” and “ obere Saiilenregion ” of Claparéde can
be recognized, then the clitellum begins at the commencement of
segment xii. ; but the epidermis covering segment xii. dorsally differs
from that lying in front by the fact that the glands are elongated
and very darkly stained; they are indeed the exact counterpart of
the clitellar gland-cells in many aquatic Oligochzeta which I have
examined when prepared in a similar fashion. These deeply
Staining cells contrast in that very particular with the clear and ver
faintly stained gland-cells of the segment in front. The clitellumis
*saddle-shaped.” The nephridia are paired structures; the first
pair are situated in segment iii. ‘The funnels have the usual position
and are not large. The nephridia themselves are without the
terminal muscular duct ; I observed the plexus formed by the “fine
tubes” of the nephridium to which Benham has called attention in
Microcheta. The external orifice of the nephridium is in front of
the ventral sete; those belonging to segment ix. open just behind
but quite independently of the spermatothece. From the eighth
segment, but more distinctly from the niuth, the nephridia are
invested by a thick sheath of clear pyriform cells with deeply
staining nuclei; the cells themselves are not much stained. These
cells, which cover the nephridia, are sometimes quite clear but more
often have a vacuolate appearance.

The alimentary canal presents the usual divisions ; there is,
however, no trace at all of a gizzard—not even the slightly thickened
tract of muscle which marks a portion of the cesophagus in Ponto-
drilus. The pharynx commences in the second segment, the brain
lying rather behind the transverse furrow which separates it from
the buccal cavity, and therefore near to the posterior boundary of
segment ii. The pharynx appears to occupy the third segment
and a part of the fourth; as usual, numerous retractor muscles are
inserted into its dorsal wall. Masses of septal glands occupy the
fourth to the seventh segment ; those of the last segment are very
much smaller; the masses of unicellular glands of successive seg-
ments are connected by fibrous strands which pass through the
septa. The cesophagus passes straight back to the twelfth segment,
where it opens into the intestine. It is nowhere ee ee just

7

704 MR. F. E. BEDDARD ON NEW [Dec. 20,

where it passes into the intestine ; the latter tube is ciliated through-
out. In the ixth segment a pair of ventrally situated calciferous
glands arise from the cesophagus. The lumen of these is much
divided ; they are very vascular.

The circulatory system consists only of two longitudinal trunks—the
dorsal and ventral vessels ; I could find neither supra-intestinal nor
subnervian. Another pair of longitudinal vessels exist in the anterior
region of the body; these arise one on each side from the free
extremity of the calciferous glands, and pass forwards through the
septal glands. The last pair of hearts are in segment xi. ; in front
of these are two pairs which are equally large.

The two pair of testes are in x. and xi.; corresponding to them
are two pairs of ciliated rosettes ; the single sperm-duct of each side
opens on to the xviith segment, and there are no glands of any kind
or penial setz associated with these orifices. One pair of sperma-
tothece open on to the anterior boundary of segment ix.; they are
simple oval pouches without diverticula and were full of sperm.

The sperm-sacs have an arrangement which is unusual among
Earthworms in general and hitherto unknown in this particular
family ; they lie in segments ix. and xii., the intermediate segments
being occupied by masses of developing sperm unenclosed by any
membrane. The sperm-sacs of segments ix. and xii. are attached
to the posterior and anterior septa respectively of their segments
respectively and are racemose in form.

The ovaries lie in segment xiii. attached, as usual, to the front
septum of the segment ; they lie just above the nerve-cord, but below
the ventral blood-vessel, and in the middle line are squeezed almost
flat between the blood-vessel and the nerve-cord. In a continuous
series of longitudinal sections the ovary of one side is seen to pass
into that of the opposite side without any break, though the middle
partis rather thinner. This is one of the very few Oligocheta with
an unpaired ovary ; olosoma is another instance, but in that
Annelid the ovary is not plainly made up of two fused halves as it is
in the species here described. Quite recently Schneider’ has de-
scribed a Rhinodrilus with a single ovary in segment xvii.: in
view of the constancy in the position of the ovary, this statement in
my opinion requires verification. The ripe ova are invariably sur-
rounded by a follicle of relatively considerable thickness; this follicle
has a fibrillated appearance, and there are numerous interspersed
nuclei. There were ova, free from the follicle, within the mouth of
the oviduct. The oviducts open on to the exterior part in front of
the ventral sete. There are no egg-sacs.

It is clear that this worm should be referred to the family
Geoscolecidz, but it is not clear as to which genus of that family
it most nearly approaches: in the first place, it should be noted
that Ilyogenia is in certain respects a somewhat degenerate form
when compared with other Geoscolecide ; this would in any case
render the decision as to its affinities a matter of difficulty. The

genus is so far degenerated that it possesses no gizzard, not even the
faintest vestige of one; the nephridia, which in other Geosco-
lecidz have a large terminal end sac, very often with a capacious
cecum attached, are totally without anything of the kind. Another
indication of a low position among the terricolous Oligocheta is
perhaps the opening of the sperm-ducts upon the xviith segment ;
we find that this segment is the one which bears the pores in question
in the genus Ocnerodrilus and also in Microdrilus and Microscolex.
It is a coincidence, though probably no more, that there is but one
pair of calciferous glands and that these are in the ninth segment; in
three low forms of terrestrial Oligocheta we meet with exactly the
same condition of the calciferous glands, viz., in Ocnerodrilus*, Gor-
diodrilus *, and in the Acanthodrilid Kerria.2 As, however, there are
Geoscolecids (such as Microcheéa) in which the calciferous glands are
similarly reduced to one pair, but which are evidently not degenerate
forms, too much stress cannot be prudently laid upon the point of
similarity to the three genera aforementioned.

Rosa* and I° have independently pointed out that the family
Geoscolecidz can be most conveniently divided into two subfamilies,
confined respectively (with the exception only of Pontoscolex, which
is cosmopolitan) to the Old and to the New World; I need not
again go into the matter here, as the reasons which led me to this
conclusion have been fully given in the paper quoted below. The
present genus iuterferes with the symmetry of this proposed
arrangement ; it evidently belongs in structure to the New World
section of the family, but lives in the Old World. The spermato-
thecz lie in front of the testes and the other reproductive organs,
and there are no copulatory papillz.

The genus I/yogenia agrees with no other genus in every point:
the form and position of the sperm-sacs are unique in the family ;
the ventral position of the nephridiopores is characteristic of the
genus Geoscolex, with which, however, I/yogenia has no other marked
points of resemblance. It comes nearest, perhaps, to Anteus and
Rhinodrilus ; but differs from both of these genera in a number of
small differences, which are, in my opinion, collectively at least, of
sufficient importance to justify its distinction by a separate generic
name.

2. On the Presence of a Branchial Basket in Myzine
glutinosa. By R. H. Burne, B.A., F.Z.S., Anatomical
Assistant at the Royal College of Surgeons of England.

[Received December 6, 1892.]
(Plate XLVII.)

One would expect the branchial basket, which forms such a large
and striking part of the skeleton of the Lampreys, to be present, at
least to some extent, in their nearest allies, the Hags; and, in fact,
such is the case, for in 1835 Johannes Miiller, in his work upon the
Myxinoids*, described and figured a small triradiate piece of cartilage
supporting the anterior and dorsal faces of the cutaneo-cesophageal
duct of Bdellostoma, which cartilagéno doubt is the homologue of
a branchial basket. Again, in 1883 Parker ® mentioned this carti-
laginous support to the cutaneo-cesophageal duct of Bdellostoma,
representing it as an irregular plate having the same position as
Miiller’s triradiate cartilage.

Manifestly, as far as Bdellostoma is concerned, there is a branchial
skeleton which, although present on one side only, cannot well be
anything but a branchial basket in a very much reduced condition.
This being the case, one would naturally expect to find some such
supporting structure to the gill-tubes of Myzine glutinosa, but
neither Miiller, Parker, nor, as far as I can discover, any other
observer has found anything answering to it; I fancy, however, that
Miller implies in a passage which I quote below * that he believed
that some such branchial skeleton was present, although he was
unable to actually demonstrate it.

While lately preparing a series of Marsipobranch skeletons for
the Museum of the Royal College of Surgeons, I naturally was on
the look-out for this cartilage both in Bdellostoma and Myzine.

In Bdellostoma I found that in the main it answered very well to
Miiller’s figure and description, although it is apparently liable to
vary in shape, as will be seen by referring to my drawings (see Plate
XLVII. figs. 5 and 6, which represent the cartilage as present in the
two specimens I dissected). Fig. 6 corresponds very much to Miiller’s
drawing ; fig. 5, however, although constructed on the same triradiate
plan, is a good deal more complicated by means of angles and
processes ; this variation in shape is still more marked in Parker’s
figure ‘. None of the true gill-tubes on either side had any supporting
skeleton. We may say, then, with regard to Bdellostoma, that the
branchial basket is represented upon the left side only by a small
plate of cartilage, usually more or less triradiate, supporting the
anterior dorsal wall of the cutaneo-cesophageal duct.

Let us now consider the branchial basket in Mywine glutinosa.
Upon removing the body-wall on the left side and clearing the gill-
tubes of fat, a small piece of cartilage (fig.1, A, Plate XLVII.) can be
seen lying on the lateral wall of the cutaneo-cesophageal duct ; it may
be said to consist of a rectangular rod-like body produced at each
corner into a ray ; of these the two dorsal and the posterior ventral
seem to answer to the three rays of the branchial basket of Bdello-
stoma; the relations of the fourth ray (figs. 1 & 3, B), however, point
it out as being something different, for, leaving the cutaneo-ceso-
phageal duct, it runs forward as a fine bar of cartilage, which bends
beneath the confluent gill-tubes, spreading out as it does so into a thin
sheet, to form, as it were, a sling for the support of the gill-tubes.

On the right side of the animal the structural conditions are con-
siderably simpler, owing chiefly to the absence of a cutaneo-
cesophageal duct: the branchial basket here is represented merely by
a cartilaginous ring (figs. 2 & 4, C) which surrounds the fused gill-
tubes and supports them much in the same way as on the opposite
side, the anterior part of the ring being broadened out into a sling-
like plate, the posterior being thin and rod-like.

The branchial basket of Myzine can be conveniently divided up
into two parts: the one, unpaired, related to the cutaneo-cesophageal
duct and comparable to the triradiate cartilage of Bdellostoma ; the
other paired, and acting as a support to the true gill-tubes.

Owing to the small size of this branchial skeleton in Mywine, it
is impossible without the microscope to determine whether it ig
composed of cartilage or no. To be certain upon this point I had
some sections of it cut, which upon examination showed precisely the
same structure as the cartilage of the branchial basket of Petromyzon
fluviatilis ; that is to say, a feeble soft form of cartilage, the cells large
and varying greatly in size and shape, the cement-substance between
them thin—in fact, much the same as the cartilage at the sides of the
notochord of the Lamprey described by Gegenbaur *.

Although some sort of branchial basket was to be expected in
Myzine, yet this, I think, is specially interesting in that, besides

the support to the cutaneo-cesophageal duct, there is also present a
skeleton to the true gill-tubes on both sides, thus to a certain very
slight extent bridging over the gap between the small unpaired
basket of Bdellostoma on the one hand and the enormous com-
plex branchial basket of the Lamprey on the other. It is worthy of
note that in Bdellostoma, a creature which approaches the Lamprey
very nearly in the structure and general form of its gills, the gill-
skeleton is reduced to a minimum, whereas Myzine, with its highly
specialized gills, in its gill-skeleton inclines towards the perfection of
the Lamprey.

In conclusion I wish to thank Professor Stewart for the kind way
in which, by criticism and suggestions, he has allowed me to profit by
his experience.

LIST OF THE PUBLICATIONS

OF THE

ZOOLOGICAL SOCIETY OF LONDON,

THE scientific publications of the Zoological Society of London
are of two kinds—“ Proceedings,” published in an octavo
form, and ‘‘ Transactions,” in quarto.

According to the present arrangements, the ‘ Proceedings”
contain not only notices of all business transacted at the scien-
tific meetings, but also all the papers read at such meetings
and recommended to be published in the “‘ Proceedings ”’ by
the Committee of Publication. A large number of coloured
plates and engravings are attached to each annual volume of
the “ Proceedings,” to illustrate the new or otherwise remark-
able species of animals described in them. Amongst such
illustrations, figures of the new or rare species acquired in a
living state for the Society’s Gardens are often given.

The “ Proceedings” for each year are issued in four parts,
on the first of the months of June, August, October, and
April, the part published in April completing the volume for
the preceding year.

The ‘ Transactions ”’ contain such of the more important
communications made to the scientific meetings of the Society
as, on account of the nature of the plates required to illustrate
them, are better adapted for publication in the quarto form.
They are issued at irregular intervals.

Fellows and Corresponding Members, upon payment of
a Subscription of One Guinea before the day of the Anni-
versary Meeting in each year, are entitled to receive all the
Society’s Publications for the year. They are likewise
entitled to purchase the Publications of the Society at 25 per
‘cent. less than the price charged for them to the Public. A
further reduction of 25 per cent. is made upon purchases of
Publications issued prior to 1871, if they exceed the value of
five pounds.

The following is a complete list of the publications of
the Society already issued. They may be obtained at
the Society’s Office (8 Hanover Square, W.), at Messrs.
Longmans’, the Society’s publishers (Paternoster Row, E.C.),
or through any bookseller.

LIST OF THE PUBLICATIONS

OF THE

ZOOLOGICAL SOCIETY OF LONDON.

THE scientific publications of the Zoological Society of London
are of two kinds—“ Proceedings,” published in an octavo
form, and “ Transactions,” in quarto.

According to the present arrangements, the ‘‘ Proceedings”
contain not only notices of all business transacted at the scien-
tific meetings, but also all the papers read at such meetings
and recommended to be published in the ‘‘ Proceedings ” by
the Committee of Publication. A large number of coloured
plates and engravings are attached to each annual volume of
the “ Proceedings,” to illustrate the new or otherwise remark-
able species of animals described in them. Amongst such
illustrations, figures of the new or rare species acquired in a
living state for the Society’s Gardens are often given.

The “ Proceedings” for each year are issued in four parts,
on the first of the months of June, August, October, and
April, the part published in April completing the volume for
the preceding year.

The “ Transactions” contain such of the more important
communications made to the scientific meetings of the Society
as, on account of the nature of the plates required to illustrate
them, are better adapted for publication in the quarto form.
They are issued at irregular intervals.

Fellows and Corresponding Members, upon payment of
a Subscription of One Guinea before the day of the Anni-
versary Meeting in each year, are entitled to receive all the
Society’s Publications for the year. They are likewise
entitled to purchase the Publications of the Society at 25 per
cent. less than the price charged for them to the Public. A
further reduction of 25 per cent. is made upon purchases of
Publications issued prior to 1871, if they exceed the value of
five pounds.

The following is a complete list of the publications of
the Society already issued. They may be obtained at
the Society’s Office (8 Hanover Square, W.), at Messrs.
Longmans’, the Society’s publishers (Paternoster Row, E.C.),
or through any bookseller.
