1.—On a Tooth of Ceratodus and a Dinosaurian Claw from
the Lower Jurassic of Victoria, Australia. By A. Smita
Woopwarp, LL.D., F.R.S., of the British Museum.
[Plate I.]
Tue Jurassic Vertebrate fauna of the Australian region is
still almost unknown, some Ganoid fishes * and, perhaps, a
few small Dinosaurian bones f being the only fossils repre-
senting it hitherto described. A tooth of Ceratodus and a
Dinosaurian claw discovered by Mr. W. H. Ferguson in the
Lower Jurassic cliffs of Cape Patterson on the south coast of
Victoria are thus of special interest. I am indebted to
Prof. J. W. Gregory, F.R.S., for the opportunity of studying
these specimens.

2 Dr. A. 8. Woodward on a Tooth of Ceratodus
The tooth of Ceratodus (P1. I. fig. 1) is firmly fixed to
a recognizable piece of the splenial bone, and is therefore
proved to belong to the left side of the lower jaw. It unfor-
tunately lacks the foremost denticle, but clearly agrees with
the majority of the Mesozoic teeth of Ceratodus in possessing
only four denticles altogether. It is thick and robust, with
the grinding-surface slightly convex, but wavy, and marked
by a very prominent coarse network of ridges (fig. 1). It is
specially remarkable for the long and narrow shape of its
crown, which is bounded on the inner side by a nearly straight
margin, not angulated opposite the second or third denticle.
So far as can be determined from a fragment, the foremost
denticle of the tooth appears to have been relatively large,
while the others rapidly decrease in size backwards. The
second and third denticles are sharply compressed to an acute
outer edge, and are separated by deep notches at the outer
margin (fig. 1 a), though not continued as conspicuous ridges
on the crown. ‘Lheir long axes are not oblique, but directed
nearly at right angles to the inner margin. ‘The fourth or
hindmost denticle is comparatively blunt. Fine horizontal
lines of growth are seen on the flattened inner (fig. 1b) and
outer faces of the tooth.
The specimen thus described differs from all the known
Mesozoic teeth of Ceratodus in its narrowness, combined with
the straightness of its inner margin and the direction of its
second and third denticles. In these respects, it is interesting
to observe, the tooth more nearly approaches that of the
existing Ceratodus or Neoceratodus ot Queensland (fig. 2),
and its only striking difference from the latter consists in its
having four denticles instead of six. The multiplication of
the denticles has already been observed in the teeth of certain
sharks as they are traced onwards in time*; the same
phenomenon obviously occurs in Ceratodus.
There is, therefore, no doubt that the tooth from Cape
Patterson represents a new species, which may be named ~
Ceratodus avus. The fossil proves for the first time that the
remarkable Dipnoan genus to which it belongs had already
reached the Australian region so long ago as the early part of
the Jurassic period. At that epoch Ceratodus was still living
both in Europe f and in North America f, while it survived

and a Dinosaurian Claw. 3
in the African and South American regions at least until the
Cretaceous period *.
In the same rock as that from which the tooth of Ceratodus
was obtained at Cape Patterson Mr. Ferguson found the
terminal phalangeal bone shown in fig. 3. Among Jurassic
fossils this specimen can only be compared with the claw of
a carnivorous Dinosaur, and there is little doubt that it
represents a genus more or less related to Megalosaurus +.
The bone has decayed somewhat in the upper part of its
proximal end, but is otherwise well preserved and displays its
principal characters, The phalangeal is laterally com-
pressed, so that its greatest transverse diameter is somewhat
Jess than its original depth at the proximal end. The distal
tapering half of the bone is only gently curved downwards,
but at the same time bends slightly to the left side. The
distal half of the lateral face is marked with the usual deep
longitudinal groove connected with the fixing and nourishment
of the horny claw which originally ensheathed the bone. The
proximal end (fig. 3a) is divided, as usual, by a median
vertical ridge into two facettes, which are nearly flat. For
comparison with this specimen one of the finest known
Megalosaurian claws from the English Wealden is shown in
fig. 4. The latter is shorter and stouter than the former, and
its deep lateral groove extends further backwards; but the
general resemblance between the two fossils is very striking.
It is to be hoped that further diligent search may be made
at Cape Patterson to recover the Vertebrate fauna indicated
by these fragmentary fossils. ‘The discovery of the terrestrial
and freshwater life of the Australian region during the
Jurassic period would supply a most important deficiency in
paleontological knowledge.

4 Mr. J. N. Halbert on Irish Hydrachnida.
I].—Notes on Irish Hydrachnida ; with Descriptions of a
new Genus and Two new Species. By J. N. HAvBERT.
[Plate II.]
THE following paper contains records of some species of new
or rare Hydrachnida selected from a large amount of material
found in various localities in Ireland during the last five years.
Of these species two appear not to have been previously
described ; one of them proves to be the type of a new genus,
while of the remaining species eight are here recorded for the
first time from the Britannic * area.
It was originally intended to reserve the new mites for
description in a general list of the Irish Hydrachnid fauna
which is being prepared. Before such a list can be com-
pleted, however, it is necessary to carry out some further
collecting in certain parts of the country, and it seems more
satisfactory to record the new species without further delay.
The most interesting of the new mites is one of which [
was fortunate enough to find fully developed specimens when
collecting last May in the south-west of Ireland. The species
in question seems to bean extremely isolated form, possessing
a combination of characters which at once distinguish it from
any of the known genera. It would be easy to briefly define
a new genus for the reception of this mite by referring to the
structure of a very few organs, such as the palps, legs, Ke. ;
in a group like the Hydrachnida, however, where there is
such a great variety of structural detail, it seems especially
necessary to rely on a combination of various characters in
the formation of new genera.
JI have to acknowledge the assistance of the Irish Fauna
and Flora Committee supported by the Royal Society, and
also of the same Committee when acting under the auspices
of the Royal Irish Academy: several grants enabled me to
collect in distant parts of the country.
The nomenclature used in the following list is that of the
‘Tierreich’? (“ Hydrachnide und Halacaride,” Piersig and
Lohmann, Lieferung 13, 1901).
* The use of the word Britannic instead of British for faunistic
purposes has been proposed by Professor G. H. Carpenter, as the latter
term is now so frequently used to distinguish records referring to Great
Britain alone (‘ Irish Naturalist,’ vol. xv. p. 15).

area situated between the fourth epimera, flanked on each
side by a triangular plate, in which are imbedded three
genital suckers of the Sygrobates type. Palps with the
penultimate segment angularly swollen on the ventral
surface and armed with two stout chitinous teeth; fifth
segment ending in an exceedingly fine point. [First pair of
legs modified, the terminal segment deeply excavated on its
upper margin, with a broad-shanked bifid claw articulating
deeply in the segment, and, in the type species, with a
terminal membrane. The three posterior pairs of legs are
provided with swimming-hairs.
It will be seen from this short diagnosis that the genus
Momonia possesses a very anomalous combination of characters
which renders the placing of it in a satisfactory position in
the Hydrachnid series a matter of some difficulty. On the
whole, however, it shows affinities with the genera J/idea,
Mideopsis, &c., and it seems to me that it should be placed
in an intermediate position between these genera and the
HHygrobates group.
Momonia falcipalpis fF, sp. n.
(Pl. II. figs. 1-4.)
Male.—Body slightly longer than broad, evenly rounded
posteriorly, and narrowed towards the front margin, where
there are two hair-papille. Seen from the side the dorsal
outline is moderately convex and the ventral surface flat over
the epimeral area; thickness of the body dorso-ventrally
about three fifths of the total length. IJntegument highly
chitinized, with a dorsal groove running round close to the
body-margin; in this groove are placed at least six pairs of

chitinous hair-bearing glands. The greater part of the dorsal
area is covered by a large shield with sinuous side-margins
bounded by the dorsal groove, the rounded posterior margin
reaching to the end of the body. This plate is wrinkled
longitudinally, and under a high magnification it is seen to
have a finely shagreened appearance as well as polygonal
reticulations. In front of this large shield lies a short broad
plate, emarginate anteriorly, and rather less than half the
breadth of the dorsal shield. The dark-pigmented eyes,
separated by an interval of about 176 yp, are situated close to
the front margin of the body. On the inner side of each eye-
group stands a conspicuous hair-papilla.
The greater part of the ventral side is occupied by the
epimeral plates ; the first and second epimera are of the usual
shape—except that the first epimeron is very narrow and
tapers inwardly into a rather fine point—separated by an
extremely narrow interval from the third epimera. The last
are quadrilateral in outline, with the front and hinder margins
sloping downwards. The fourth epimeron is extremely large
and characteristic ; the inner margin is continued for a short
distance in a line with that of the third epimeron, it then
bends suddenly outwards and downwards in a sinuous line to
near the hinder margin of the body, fusing with the chitinous.
integument of the sides of the body. Near the middle of the
fourth epimeral area on each side is a group of long hairs.
The epimera are all finely shagreened and reticulated in the
same way as the dorsal shield.
The genital area lies in the anterior space between the
fourth epimera ; it is flanked on each side by a long triangular
plate, which carries three genital suckers, placed one behind
the other, similar in structure to those found in Hygrobates
and allied genera. A transverse chitinous plate, in which is
imbedded the anal opening, occupies the remaining inter-
epimeral space.
The capitulum is rather small, projecting downwards for
part of its length beyond the ventral outline of the body;
maxillary shield measuring about 110 mw in length (not in-
cluding subcutaneous process) and 77 w in breadth.
The palps are small, the five segments measured along
their dorsal margins are 30 pw, 75 w, 50 w, 85 w, 55 w respec-
tively ; segments 1, 2, and 3 may be compared with those of
Mideopsis ; 2 and 3 are furnished with a number of rather
stout hairs on the dorsal surface; 4 is the longest palp-
segment, it is slightly convex dorsally, with two long fine
hairs, ventral surface produced beyond the middle into a well-
marked angular prominence, on which are two short stout

teeth placed close to the inner side of the segment; 5 is
nearly as broad at base as the distal margin of 4, tapering
gradually into a long sharp point; the upper and lower surfaces
are each armed with a long hair and a sharp spine; on the
outer side close to the base is another spine.
First pair of legs (length about 814 «) modified, without
swimming-cilia, slightly longer than the body, the segments
gradually increasing in length from 1 to 5. Segment 1 very
short, 2 and 3 straight, with a number of long bristles; 4
curved, with the ventral distal margin notched ; 5 straight
(length 260 «), broader than preceding segments, and nar-
rowing towards the distal extremity, on which are seven or
eight long hairs. Segment 6 (fig. 3) articulates with a
conical projection on the penultimate segment, short, with
convex sides, very deeply hollowed out on its upper distal
margin ; a powerful claw-like structure with a broad shank
and sharply bent bifid extremity articulates with the inner
part of the excavation ; a few long hairs and a peculiar cone-
shaped membrane project from the extremity of the segment.
The last three pairs of legs do not present any remarkable
characters ; they increase in length from before backwards
and are provided with long swimming-cilia; the terminal
segments are armed with two recurved tridentate claws
resembling those of Brachypoda.
During life the colour was a pale yellowish green, marked
on the dorsal surface with reddish brown; Malpighian area
yellow, indicated anteriorly by four lobes arranged across the
body.

Locality—Two fully developed examples of this species
were found amongst a thick growth of Callitriche in Loos-
caunagh Lough, about ten miles from Killarney, May 1905.
From the peculiar modification of the first pair of legs there
is no doubt that the specimens are males.
The type specimens are in the Dublin Natural History

Arrhenurus octagonus, sp.n. (PI. I. fig. 5.)
Male.—Colour during life red, with ill-defined darker
markings on the back. In dorsal view the body is roughly
octagonal in shape, the posterior half being somewhat similar
in outline to the anterior. Front margin almost straight,
about equal to half the width of the body ; all other margins
very slightly emarginate, There are no conspicuous dorsal
humps, but in the middle of the posterior margin there is a
deep excavation, with a prominence on each side on which
is a long hair. Dorsal furrow roughly circular in form,
enclosing a comparatively small area (length 537 y) of the
middle of the back.
The appendage is short, measuring about a sixth of the
entire length of the animal and about four fifths as broad; in
dorsal view mostly covered by the hinder part of the main
body ; sides of the appendage hardly constricted at base,
gradually narrowing inwards and blending with the hinder
margin. Posterior dorsal margin with a wide excavation
reaching from side to side; posterior ventral margin slightly
sinuate, pierced in the middle by a narrow deep indentation,
which widens noticeably at its deepest part and reaches the
base of the appendage. The pettolus is composed of two
finely pointed pieces, which are closely approximated in the —
living mite, and project in the middle line very slightly
beyond the margin of the appendage. There are five or six
pairs of very short hairs on the end of the body.
Genital plates large, sinuate anteriorly, and gradually
narrowing towards the sides of the body, which they do not
overreach, pimeral plates remarkably long and narrow,
rather closely resembling those of A. s¢nuator, Miiller.
Palps stoutly built, with prominent distal angles to the
segments. ‘The inner surface of the second segment seems
to be without a hair-pad, but carries a few stout unfeathered
bristles. Fourth segment with a long straight spine near the
inner distal corner and a widely forked tactile hair on the
apical margin.
The legs do not present any unusual characters ; they are
rather stout, of moderate length, and the fourth segment of
the last pair is without a spur.

Locality.— Found ina pond at Fenagh, Co. Carlow, by
Mr. Denis R. Pack-Beresford, M.R.I.A., during the month
of August 1903.
Type specimen deposited in the Dublin Natural History
Museum (register no. 180, 1906).
Arrhenurus Leuckartt, Piersig.
Both sexes of this mite were collected in the same locality
as the preceding species by Mr. Beresford. It is apparently
one of our rarest Arrhenur?, these being the only Irish
specimens that I have seen. Dr. George includes it in his
Lincolnshire list, and Mr. Soar reports it from the Norfolk
Broads.
Arrhenurus Neumant, Piersig.
This is another addition to the list of Irish Arrhenuri
published a few years ago*. I found several specimens
(g and ¢) last year in Looscaunagh Lough in May, and
also in Glendalough Lake, Connemara, in the following
autumn. Mr. W. Williamson has taken it in Scotland
(Trans, Edinb, Field-Nat. and Micros. Soc. Session 1905-
1906).
Arrhenurus Stecki, Koenike.
1894, “ Zur Hydrachniden-Synonymie,” Zool. Anz. xvii. p. 274, fig. 5.
A male of this rare species occurred in a bog-pool almost
filled with Sphagnum near Ross, Co. Galway, in September
1905. ‘This is the smallest species of the genus as yet found
in Ireland, my specimen measuring but 572 mw in length.
The colour was pale yellow, with two black blotches showing
through behind the epimera.
Localities—Up to the present time this species has been
recorded from Switzerland, where it was found in a similar
kind of locality (Moosseedorf-See bei Bern), Germany, and
Norway (1899). Dr. George has recorded it from Lincoln-
shire (‘ The Naturalist,’ 1905, p. 25).

Fortunately the single specimen taken is a male and shows
the characteristic modification of the fourth pair of legs, as

This species is allied to P. nodata, Miller, and P. contro-
versiosa, Piersig, but differs sufficiently from both in the
structure of the genital area, palps, and especially in the
armature of the terminal segment of the third pair of legs in
the male. The species was first described in 1896 by
Dr. Thor, and was supposed by Dr. Piersig to be synonymous
with P. controversiosa, but the more detailed description
published in the above reference clearly shows the distinctions
between the species.
The only Irish specimens examined were taken by
Mr. W. F. de Vismes Kane in Drumreaske Lake, Co.
Monaghan.
*Panisus Michaeli, Koen. (PI. II. fig. 6.)
1896. Zool. Anzeiger, xix. p. 356,
When in the west of Ireland in the spring of 1901 I
found an Hydrachnid of the genus Panisus amongst water-
plants in a small stream which flows into the sea at the head
of Ballysadare Bay. On examination it agreed closely with
the description of P. Michaeli, Koenike, except that the
chitinous marginal piates of the dorsal surface numbered four
on each side in my specimen, instead of five, as recorded for
P. Michaeli. Onsending drawings of the mite to Dr. Koenike,
he was good enough to assure me that my species is identical
with P. Michaeli. ‘There are in reality only four marginal
plates on each side in that species; the statement that there
12 Mr. J. N. Halbert on Trish Hydrachnida.
were five was due to the outlines of the plates not being
clearly visible at the time the preliminary description was
made. There are sixteen chitinous plates on the dorsal
surface, arranged as follows :—A middle series, consisting of
a large plate between the eyes; behind this are three small
circular plates, arranged on each side of the middle line;
and, finally, a large terminal plate, sinuate in front, with the
postero-lateral corners produced into pointed processes. The
eight marginal plates are arranged in a line on each side of
the body ; the most anterior of these sends forward a long
narrow prolongation on the outside of the eye. All of the
dorsal plates are coarsely areolated towards their margins and
more finely in the centres; they are also very irregular in
outline, differing considerably on each side of the body.
The species seems to be very local, and as I have seen no
reference to figures, a drawing (fig. 6) of the dorsal surface
is given; the areolation of only the terminal plate is indicated.
Localities—Panisus Michaeli was first recorded from
Switzerland, where it was discovered by Dr. A. D. Michael
at Davos; and Dr. Sig. Thor has recently recorded it from
Norway. I have also seen a specimen collected by Mr.
William Evans near Bolerno, Scotland, in the autumn of
last year,
Thyas longtrostris, Piersig.
This very distinct species is of local occurrence in Ireland.
I once found amongst Callitriche ina small pool near Ken-
mare many specimens, some of which were very large,
measuring nearly 3 mm. in length. In his paper on the
British species of Thyas (‘Science Gossip,’ viii. p. 46)
Dr. George refers to the occurrence of this species in Ireland,
and Mr. C. D. Soar has since found it in the Norfolk Broads.

Second perwopods : first joint narrow-oblong, subequal to
the third and fourth united. Dactylus almost straight and
not flexed, as long as the third joint.
Third and fourth pereopods subequal ; first joints oblong,
twice as long as wide. Dactyli longer than the fifth joint,
especially in young specimens, tapering gradually, not flexed.
Fifth perwopods shorter than the third and fourth, the first
joint much wider, with. the convex, obscurely serrate hind
margin produced nearly to the middle of the third joint.
Dactylus as long as the fourth joint, which is shorter than
the fifth.
Third uropods: rami subequal, nearly twice as long as the
peduncle, with fine spines on both margins.
Telson reaching to about one fourth the length of the rami
of the third uropods, deeply notched at the end, with a minute
notch on the tip of each division.

IV.—Rhynchotal Notes—XXXVIII. By W. L. Disrant.
Tue following descriptions and notes are preparatory to
a synonymical catalogue of the family Fulgoride which
I have now in preparation. I reserve synopses of the
genera to the catalogue itself, as there are genera which
I have not seen and others which have still to be described,
which render the formation of such keys impossible for
the present.

Since using the name Aphana for this genus (Faun. B. Tf.
supra), when I thought I had solved the synonymic problem,
I have found that Guérin, in first describing this-cenus under
the name of Aphena (Voy. ‘ Coquille,’ Zool. ii. (2) i. p. 184,
1832), gave as the type his A. fuscata from New Guinea. ©
This genus is therefore structurally distinct from other species
included subsequently in Aphena=Aphana, Burm., and
Penthicodes thus becomes available. Blanchard regarded the
name Aphana as preoccupied by Aphanus, Lap., an argument
I did not and do not follow ; but the type of Guérin’s Aphena
settles the question.

IX.—Alternation of Generations, Metamorphosis, and
Direct Development. By W. WEDEKIND*.
In my previous writings on the subject of parthenogenesis I
have already pointed out that, in my opinion, so-called asexual
reproduction was everywhere the primitive method, and that
it is only in the course of phyletic development, through the
series—segment, bud, spore, and female and male partheno-
ovum,—that at last the ovum needing fertilization and the
sperm belonging to it have arisen therefrom. It follows,
therefore, that all organisms with sexual reproduction must
be derived from asexual ancestors. According to the bio-
genetic law of recapitulation this phylogeny must also very
generally have been repeated in the ontogeny, and I would,
moreover, venture to assume that in earlier epochs the course
of the entire ontogeny was not yet by any means so rapid as
it usually is to-day. It therefore follows from our theory
that the ancestral stage of asexual reproduction must formerly
have still been displayed in the development of each indi-
vidual, and that it was only gradually that it became more
and more suppressed,
According to this interpretation, then, in the first instance
from every fertilized ovum at least an asexual generation
must again have developed, and only from this has there
arisen once more the ultimate form with sexual reproduction.
* Translated by E. E. Austen from the ‘Zoologischer Anzeiger,’
Ld, xxix. Nos. 25/26 (March 6, 1906), pp. 790-795,
Generations, Metamorphosis, Le. 39
In other words, alternation of generations was universally
the most primitive form of ontogeny, and consequently it 1s
not of merely secondary origin through selection, but, on the
contrary, it has persisted only here and there. ‘I'hus, on thie
basis of the theory of descent and the biogenetic law of re-
capitulation we arrive at this simple explanation: — alternation
of generations is (nothing more than) the ontogenetic repetition
of the phylogenetic progressive developnent from lower
organisms with asexual reproduction into higher species with
dissociated sexual products. In this way, too, the different
varieties (heterogony &c.) are easily intelligible.
When, in consequence of continued acceleration of the
ontogeny, the first asexual generation produces, instead of
the previous numerous progeny, only a single offspring, and
when, moreover, this single descendant no longer severs itselt
from the mother, but proceeds from it more or less con-
tinuously, the ontogeny assumes the form of metamorphosis.
The latter has therefore arisen from alternation of generations
by a process of constant abridgement; and thus we can
shortly define metamorphosis as a curtailed alternation of
generations.
In all cases, then, it is only through continuous acceleration
of the ontogeny that direct development, as we find it to-day,
has arisen from alternation of generations and metamorpliosis.
Direct development is everywhere the secondary process,
which in consequence of its great rapidity is also well-nigh
incomprehensible, whereas it is much easier for us to picture
to ourselves phylogeny, which is a million times slower, and
also an earlier and less rapid ontogeny.
In this way, therefore, alternation of generations and
metamorphosis lose all that was previously inexplicable and
become easily intelligible to us by means of the theory of
descent, when we regard them simply as ontogenetic recapitu-
lations of the development of the species. They are no new
processes, which have only arisen at a later date, but, on the
contrary, the oldest forms of ontogeny, which, on a further
development of the organic world, should it chance to occur
later on, will tend towards direct development, but have not
originated from the latter. ‘heir occurrence to-day represents
only tie last remnants of earlier and probably much more
widely diffused conditions, just as is the case as regards
modern parthenogenesis.
A material advantage of this mode of interpretation, there-
fore, is that it is nowhere necessary for us to assume the
existence of a cwnogenesis, with retarded and altered develop-
ment. Ontogeny consequently makes no detours, but merely
40 Mr. W. Wedekind on Alternation of
goes on developing continually in a tachygenesis which
becomes constantly more and more accelerated.
Moreover, up to the present it has nowhere been shown
that the retardation of ontogeny is only secondary. Fritz
Miiller, too, who is much quoted to this end, certainly brings
forward in his well-known memoir many an instance of
tachygenesis, and also maintains that development is
frequently falsified by the struggle for existence which tlie
free-living larvee had to undergo; he remarks that this point
needs no further elucidation, since it is self-evident, &c., Kc.
The author in question states that it is easy to understand
how even a direct course of development may again be trans-
formed through the struggle for existence into a development
with metamorphosis. But in no passage of his work does
Miiller adduce any fact whatever in favour of this assertion,
any more than the point has previously been proved by other
authors. ‘To me, too, that nature in so many instances should
have made such a retrograde step is anything but “ self-
evident” and ‘easy to understand”; and still less can I
picture to myself the znner causes of such a process, especially
since I have long ago abandoned the pious belief of my
scientific childhood in the omnipotence of selection.
The “utility”? also of such a retarded development is
absolutely incomprehensible tome. Forwhat have butterflies, -
for instance, to gain from the fact that, with a more protracted
caterpillar life, they are so much the longer exposed to the
danger of being devoured before they reach the final goal of
their development? Or wherein are they benefited by
previously as caterpillars eating up the very plants upon
which they subsequently want to live as butterflies ?
And so probably in all cases the harmfulness of a slow
development can be demonstrated at least equally as well as
the advantage ; and even when the latter is really present, it
still need not on that account be an originating cause, but is,
as I interpret it, merely the external stimulus, which, in the
case of the species in question, has led to the longer ontogeny
persisting until the present day.
In almost every instance, however, a species must derive
the greatest advantage from completing its developmental
stage as quickly as possible, in order afterwards to continue
to live quite a Jong time as an adult animal. Among insects
I need only remind the reader of the highly organized
Hymenoptera, of which the metamorphosis 1s no longer so
“complete” as is that of the beetles, butterflies and motlis,
&e. ‘Lhe metamorphosis, e. g. in the case of the bees, which,
in contrast to that exhibited by the other orders referred to,
Generations, Metamorphosis, Le. 41
lias already undergone considerable reduction, surely bears
witness to the general striving after a constantly shorter
tachygeny, although, from internal causes of which we are
still ignorant, in the case of many lower animals this has not
yet advanced so far as direct development.
As the weightiest objection to my interpretation I shall
naturally again have to encounter the views on phylogeny
which are held to-day. In the case of the lowest orders
among the Tunicata we find direct development : consequently
the alternation of generations in the higher Tunicata, which
are evidently derived from the former, can only be a secondary
acquisition, And likewise in the case also of the higher
insects, since they are said to be derived from their lower
relations which have direct development, “complete” meta-
morphosis can only be of secondary origin.
In opposition to this line of argument, however, I would
call attention to the self-evident truth that in no class of the
animal kingdom does there obtain a relation of direct descent
between its existing higher and lower orders, and to this rule
the Tunicates and Insects form no exceptions. The ancestral
form of the Tunicata was consequently not in all points
identical with the Appendicularid of the present day, but
must at least have had a divergent attribute in common
with the higher Tunicates. And thus we may naturally
just as well imagine these Archi-Tunicates as in other
respects entirely similar to the Appendicularide, but with
asexual reproduction. A portion of these, the present
Appendicularid, then branched off to one side quite early,
and displayed a very rapid and precocious transition to
sexuality, so that they, perhaps evey in consequence of this
over-speedy advance to sexual life, subsequently remained
stationary at a lower stage of the development of the phylum.
On the other hand the majority, while retaining asexual
reproduction for a longer period, continued perhaps on that
account slowly but nevertheless surely to make progress in their
phylogenetic development, until in their case also a conclusion
was reached with the attainment of sexuality in the higher
orders. Moreover, this phylogeny of varying length was
subsequently retained in the ontogeny also. Since no otlier
material difference any longer existed between the ancestral
form with asexual and the present Appendicularide with
sexual reproduction, ontogeny, too, was easily able to proceed
to direct development, while the less rapid phylogeny of the
higher orders has left its traces in their ontogeny even at the
present day.
Similarly, too, the “typical archi-normal Insect” was, in
42 Mr. W. Wedekind on Alternation of
my opinion, (not provided with wings and) not dicecious.
This ancestral form must rather have been represented by
somewhat worm-like creatures, which (just as, indeed, many
worms still do) reproduced themselves asexually and gave
rise polyphyletically to the different orders. From these, too,
there then very early branched off a portion, which likewise
again, precisely because it precociously developed the con-
dition of separate sexes, also remained stationary at the lowest
stage; while the remainder, again in consequence of longer
retention of the asexual mode of reproduction, had time to
undergo further phyletic improvement, and only at the con-
clusion of their various orthogenies also became parthenogenetic
or dicecious as the case may be. Here also the phylozeny of
varying length is then reflected again in a reduced or
“complete” metamorphosis, while the latter itself represents
no more than the “ welding together ” of the two primitive
generations,
It appears exactly as though the transition to sexual repro-
duction is also universally connected with a pause in the
orthogeny, so that, if the latter takes place rapidly or
prematurely, the whole of the rest of the organization also
generally remains stationary at a lower stage, while the slower
attainment of sexuality in the phylogeny likewise allows time
for a higher orthogeny. ‘Lhe one condition directly entails
the other, and I would term this phenomenon shortly the law
of precuocity (prematurity). A more rapid ontogeny, a direct
development, conscquently only shows that the earliest stages
of the asexual ancestors were already abandoned at a very
early period, but not that they had been altogether wanting ;
and it may also very well be that traces of them are still to
be discovered even at the present time.
Naturally my theory is not capable of direct proof, any
more than is the opposite view. I think, however, that my
theory is simpler and more natural, since by means of it,
indeed, we at once get rid of the entire cenogeny, and need
only imagine the ontogeny as baving been accelerated, but
not as having subsequently been altered, by side influences.
In this way also we should surely find less difficulty in
understanding the manifold transitions, which still frequently
occur especially between alternation of generations and meta-
morphosis, and with regard to which we may be in much
doubt as to whether we are still confronted with a reduced
alternation of generations or have before us an already
commencing metamorphosis. They are all just gradations
of one and the same phenomenon, which pass without a
break one into the other, and with which hitherto the majority
Generations, Metamorphosis, de. 43
of authors have not known how to deal correctly. Brandes
alone, in his new edition of Leuckart's work on ‘ Parasites,’
speaks on one occasion of a “ masked” alternation of genera-
tions ; but otherwise such intermediate stages are ‘always
interpreted as “commencing” alternation of generations,
But still it is by no means quite clear how such a view can
be taken. There certainly can be no question of orthogeny,
and, on the other hand, neither can any value whatever be
attributed to such “ beginnings ” from the point of view of
selection. ‘Thus it is consequently in all probability more
correct to regard them simply as purposeless remnants, and
so to consider them as we do the rudimentary organs, which,
indeed, were equally conundrums before Darwin’s time. In
the embryological works of the last few years will be found
the description of many a phenomenon which from this point
of view would be much more readily intelligible.
The regenerative faculty, too, is thus perhaps capable of
being interpreted simply as the rudiment of an earlier asexual
mode of reproduction. The ability to produce from their
asexual cell-material anew and distinet individual has gradually
been lost by the higher animals (and this is how I account
for metamorphosis also) ; but at least they have still retained
the power of continually bringing the old individual up to its
normal condition. ‘This, then, probably also explains why it
is precisely organisms with undiminished asexual reproduc-
tion (thus, the plants in an especial degree) that do not
regenerate ; and hyper-regeneration, too, is surely easy to
understand when we regard it as a more powerful remnant of
an earlier asexual reproduction.
It may be that thoughts like these, have already occurred
to one naiuralist or another, and that it was only Tunicates,
Insects, &c., that hitherto have always led to their being
abandoned again. On that account I have already dealt with
this main objection in the present paper, while I must defer
the further development of my theory in fuller detail until
somewhat later, in connexion with my thesis on partheno-
genesis and arbitrary determination of sex in the higher
animals. For it all hangs together, one thing follows from
the other, and everything rests upon a mutual basis. The
entire development of the organic world is to my mind
purely orthogenetic process, consisting in continually ad-
vaneing ‘‘sexual dissociation” of the primitively latent-
hermaphrodite (so-called asexual) original condition. Without
such a “sexuality” of the organic world, a natural force,
therefore, which has hitherto been disregarded, we shall, in
my opinion, be unable to furnish a complete explanation of
44 Dr. N. Annandale on new Barnacles.
organic life; but with a working hypothesis of this kind we
at least advance a step or two further.
Just as little as we can explain the magneto-electric
phenomena by means of mechanics alone, so do we find that
these two no longer suffice for the organic phenomena; on
the contrary, in their place also we must now assume the
existence of a special form of energy, upon which, from its
most conspicuous quality, [ bestow the designation “sexuality.”
In this force there is, of course, just as little of the super-
natural as in the other forces of nature. And that it is
likewise already capable of being expressed in figures and
is subject to mathematical treatment I shall shortly show
elsewhere in a paper on the mathematical equations of the
partheno-ova and their fertilization.

A pair of this pretty little insect was found by Mr. Row-
land Taylorin 1895. It has the general aspect of Lachnosterna
and Brahmina, from which it is impossible to dissociate it in
spite of important divergences. Its very short and prominent
anterior coxe infringe the primary characteristic of the true
Melolonthini, with which the fused abdominal segments and
general structure connect it. Its most striking feature is the
enormously elongate club of the male, consisting of three equal
joints almost as long as the elytra. The scape is about as
long as the six joints forming the stipes taken together,
these being very short, but slightly increasing in diameter as
they approach the club. In the female the club is extremely
short, and between it and the elongate first joint there are
only five joints, which are not compressed as in the male, but
are conjointly a little longer than the scape. The prothorax
is finely rugulose, the scutellum smooth and velvety, and the
elytra very irregular, with shallow depressions, variolose
punctures, and strong carine near the apices. The organs of
the mouth are rather peculiar, and the claws have a strong
curved tooth about the middle. ‘The legs and underside are
everywhere strongly punctured, and there is a greyish bloom
partially covering the sterna, abdomen, and elytra.

Two species of this genus, both inhabiting Borneo, have
previously been described. ‘The present one agrees with them
in all its essential characters, but is much larger, and, indeed,
is by far the largest of the great Lachnosterna group known
to me. In its general form and colour it is like O. princeps,
Sharp, but the long erect hairs with which the upper surface
bristles distinguish it from all its congeners, now three in
number. These hairs arise from very large punctures which
are scattered irregularly over the prothorax and front of the
head, but upon the elytra are confined to the smooth slightly
elevated coste. Another peculiar feature is found in the
shape of the prosternal process, which has the unusual form
of a transversely placed crescent, the two extremities of which
are acutely pointed but not much elevated.
A single specimen was found by Mr. Charles Hose.

I have seen only a single specimen of this also. It is
another large species, but is chiefly noticeable for its great
elongation, the elytra being four times the length of the pro-
thorax. They have no silky bloom like O. gigantea, and
their puncturation is rather feeble. Their lateral margins are
bordered with a rather wide membrane, but are not reflexe |,
as in the other species.

Mollusea.
1866. Micronycteris, J. E. Gray, P.Z.S. p. 113.—Type: Micronycteris
megalotis.
The subjoined characterization is confined to the features
in which Micronycteris differs from Glyphonycleris :—
Skull *.—Facial portion, immediately in front of orbits,
not conspicuously inflated. Basioccipital pits, antero-
internally to cochlez, shallow.
Dentition +.—? not especially modified (compare Glypho-
nycteris). Upper canines not shortened, their vertical being
about twice their antero-posterior basal diameter. The
“heel” of p® represented only by a very narrow cingulum.
Inner border of the cingulum of p' with a distinct shallow
emargination, dividing the cingulum into an antero-internal
(“cusp 6” [) and a postero-internal tubercle (‘cusp 7”).
Hars.—Conjoined by a transverse band across the head.
Outer margin of ear-conch uot distinctly concave in its
upper half.
Chin.—A triangular naked space (in skins and alcohol
specimens often contracted to a deep furrow), flanked by
two oblique warts, converging downwards.
Wings.—Tbird and fourth metacarpal subequal in length,
fifth the longest. First and second phalanx of third digit
subequal.
Species.—Four species were catalogued by Dobson in
1878: M. hirsuta, megalotis, minuta, Behni. Since that
time the following three species have been described : M.
brachyotis (Dobson, 1879), M. microtis (Miller, 1898), M.
hypoleuca (J. A. Allen, 1900). I have satisfied myself that
M. Behni is a Glyphonycteris ; the same is probably the case
with M. brachyotis ; ard M. hypoleuca is appareutly indis-
tinguish«ble from M. minuta. ‘The genus Micronycteris, as
here restricted, therefore comprises the following four
species: M. megalotis, microtis, minuta, and hirsuta.
Range.—F rom 8. Brazil and Peru to Mexico.

Mr. K. Andersen on the Bats of the
1. Micronycteris megalotis, Gray.
Teeth.— pz higher than p3 and p43 p; and p, subequal in
height (ps, often a trifle lower) ; p; in cross-section at base a
little smaller than p,.—p’ about half the height of the canine ;
p® and p* subequal in height. Tip of the principal cusp of p*
situated only very slightly in front of a vertical line through
the middle of the base of the premolar; vertical diameter of
p® about equal to antero-posterior basal diameter ; external
surface of p® convex.
Ears.—Long and broad, reaching beyond the tip of the
muzzle when laid forwards. Cross-strize on ear-conch faint
and rather ill-defined; number about 13-14; distance
between uppermost and lowermost stria about 11 mm.
In the fully adult male the transverse band between the
ears is triangular in shape, 7. e. low laterally, triangularly
raised in the middle ; a small notch at the middle of the upper
margin of the band (the top of the triangle). Immediately
behind the band, in the fronto-parietal region, a triangular
groove bordered by a horseshoe-shaped elevation of the skin ;
the median, triangularly projecting portion of the band, when
laid backwards, fits exactly to the triangular groove, as the
lid to a box; tufts of long hairs on the posterior surface
of the “lid.” The bat is no doubt able to cover and uncover:
the groove by moving the band forwards and backwards.
In females and young males the transverse band is much
lower, not conspicuously higher in the middle than laterally ;
the frontal groove is absent or, at most, very ill defined.
The frontal groove (which, to my knowledge, has not been
described by previous writers) is evidently analogous to
the frontal sac in many species of Hipposiderus. The posi-
tion is the same; the long hairs recall the hair-tuft in the
Hipposiderus sac ; and, as in the majority of Hipposideri, the
apparatus is characteristic of the male sex. A frontal con-
cavity almost identical in structure and position is found in
the males of an Oriental species of Nyctinomus (N.johorensis).
Nose-leaves.— Lancet long, 7. e. its extreme length about
equal to 1} its width at base.
Wings.—Forearm practically naked ; some short, scattered
hairs are observable on very close inspection. Wing-
membranes inserted on the ankles or the base of the meta-
tarsus. Length of forearm 31°8-38 mm.
Foot and calcar.—The foot is comparatively small, equal
to 4 or 3 the length of the lower leg. Calcar long, always
longer than the foot, and always much more than half the
length of the lower leg.
Genera Micronycteris and Glyphonycteris. 53
Tail and interfemoral.—The postcaudal portion of the
interfemoral is longer than the tail, from the anus to the tip
of the last vertebra.
Colour.—There are two extremes in the colour of the
fur :—
(1) Upperside Prout’s brown with a tinge of russet ; base
of hairs pure white or washed with ecru-drab. Underside
wood-brown, base of hairs scarcely lighter.
(2) Upperside dull dark brown without any trace of russet
tinge; base of hairs pure white or washed with ecru-drab.
Underside hair-brown.
The extremes are connected by several transitional stages.
The variation in colour is independent of the locality and, as
it seems, of the age of the individuals.
Range.—The same as that of the genus.
Remarks.—The large p; and p’*, the median position of the
principal cusp of p®, the very small notch at the middle of
the upper margin of the ear-band, the practically naked
forearm, the long hand, the small foot, long calcar, long
postcaudal interfemoral, and darker-coloured underside of the
body readily distinguish this species from M. minuta. From
M. hirsuta it differs by its smaller size and higher ear-band,
from M. microtis by its much darker colour.

Mexico.
Remarks.—The examples recorded by Mr. Miller were
from various places in 8S. Mexico (Oajaca, Colima, Jalisco) ;
the British Museum material shows that this larger race
has a much wider distribution. Judging from the series
available, it would seem that it reaches its climax (i. e. its
maximum size) in Central America.
Truly intermediate specimens between the southern race
and mexicana 1 have not seen; but three skins from
Maipure, Orinoco, thus from a border region between the
areas of the two races, are perhaps intermediate in external
dimensions (forearm 35-35°8 mm.; third metacarpal 28-7-
28°8) ; the skull of one of the individuals is, however, quite

1898. Micronycteris microtis, Gerrit S. Miller, Proc. Ac, Nat. Sci.
Phil. 1898, pt. ii. pp. 328-29, 331; Nov. 8, 1898.—Type: ¢ ad.,
skin and skull; Greytown, Nicaragua; U.S. Nat. Mus. The only
specimen recorded,
The species is known to me from the published account
only.
The principal characters, according to Miller, are these :—
Ears considerably shorter than in megalotis ; inner surface of
ear-conch with eight sharply defined cross-ridges, crowded
into the space of 5 mm.* Colour of the fur, both dorsally
aud ventrally, wood-brown, with nearly white bases to the
hairs. General size small: forearm 31 mm.
Other external features, as well as the dentition, essentially
as in M. megalotis.

21900. Micronycteris hypoleuca, J. A. Allen, Bull, Amer. Mus. N. H.
xiii. pp. 90-91; May 12, 1900.—Type: 9 ad., skin without skull;
Bouda, Santa Marta region, Colombia; New York Museum; the
only specimen on record.—Characters, according to Dr. Allen:
* About the size of .W. minuta, but white below instead of ashy, and
the basal portion of pelage above white instead of ashy white.” But
British Museum examples (skins) of M. minuta from Brazil are,
* Are the ears of the type specimen of M. microfis undamaged? My
reason for raising the question is this:—In the proportionate size of the
ears and in the cross-markings of the conch ™. hirsuta is similar to M.
megalotts. Butin two british Museum examples of JL. hirsuta the ears
are very short, reaching only a little beyond the eyes when laid forwards,
and the cross-markings on the inner surface of the conch are very strongly
defined and crowded into a space of 6-7 mm.; they are, on the whole,
puzzlingly like the type of ear described by Mr. Miller in M. microtis.
ut the ears of these two VW. Airsuta have indubitably been singed (the
b .ts may have been caught while trying to esc.:pe {rom a burning tree,
or, perhaps more likely, been found dead in a hole of a partially burnt-
down tree); though very much shrunk they have, however, preserved
their oriyinal shape ; they have simply contracted into scarcely 3 their
natural size, and, as a consequence of that, the cross-markings have
become very sharply defined, prominent beyond the plane of the conch,
and crowded into a small space, and the ear-conch thick and stiff. Is the
satce, perhaps, the case with the ears of the only specimen known of
M. microtis? If so, M. microtis is very closely related to VW. megalotis,
differing, as it seems, only in the much lighter colour of the fur (which,
however, may be indicative of a light phase only) and, perhaps, a slightly
smaller size.
56 Mr. K. Andersen on the Bats of the
some of them white, others greyish white below, and have the basa
of the hairs of the upperside white. If, therefore, there is no other
difference between M. hypoleuca and M. minuta, the former cannot
be distinguished from the latter. I understand from Dr. Allen’s
description that he had no example of M. minuta for comparison.
Teeth.—p; much lower than p,, only a little higher than
the cingulum of p .—p* much lower than p*, only a little
higher than the cingulum of the canine. Principal cusp of
p® situated near the anterior end of the tooth; vertical
diameter of p® markedly shorter than antero-posterior basal
diameter; external surface of p’ concave.
Ears.—Essentially as in M. megalotis: long and broad,
extending beyond the tip of the muzzle when laid forwards.
Cross-strize on ear-conch faint and rather ill-defined ; number
about 11-12; distance between uppermost and lowermost
stria about 10 mm.
In the fully adult male the transverse band between the
ears is as high as, or, rather, still higher than, in the male of
M. megalotis; but the median notch is extremely deep,
reaching practically to the base of the band, thus dividing it
into two distinct triangular lobes. A coat of long hairs on
the posterior surface of the band. Frontal groove as in the
male of M. megalotis.
Spirit-specimens of females are not available for examina-
tion.
Nose-leaves.—Kssentially as in M. megalotis, but lancet
comparatively a trifle shorter, its extreme length being on
average equal to about 1} its width at base.
Wings (compare the wing-indices below, p. 65).— The
metacarpals are proportionately shorter than in M. megalotis ;
an inspection of the measurements (below, pp. 64-65) will
show that whereas M. minuta has the forearm of precisely the
same length as M. m. mexicana, its metacarpals are as short
as in the small southern race, M. m. typica; this, together
with a shortening of the proximal phalanges, makes as a
tutal result a proportionately shorter hand in M.minuta. The
second phalanx of the fourth digit is practically equal to the
first phalanx (in M. mega/otis decidedly shorter than the first
phalanx).
The muscular part of the forearm is densely haired.
Membranes inserted on the ankles or the extremity of the
tibia. Forearm 36-37°5 mm.
Foot and calcar.—The foot is comparatively large, much
more than 4 the length of the lower leg. Calcear short,
always shorter than the foot, aud less than } the length of
the lower leg.
Genera Micronycteris and Gly phonycteris. 57
Tail and interfemoral.—The postcaudal portion of the
interfemoral is shorter than the tail.
Colour.—Above as in M, megalotis, below cousiderably
lighter. Upperside Prout’s brown, base of hairs white ;
underside whitish or greyish white in the middle, drab on
the flanks.
Range.—Brazil, from Santa Catherina in the south to
Para in the north. Extending to Colombia, if M. hypoleuca
is identical with M. minuta.
Specimens examined.—11, from:—Santa Catherina (3) ;
Para (4) ; ‘‘ Brazil”’ (4).
Remarks.-—On hasty inspection M. minuta bears no small
resemblance to M. megalotis. The two species are practically
alike in the shape of the skull, in the ears and nose-leaves,
and in the general size; M. minuta is not, as its technical
name might suggest, smaller than M. megalotis. But
M. minuta differs in the following important respects :—
In the very conspicuous reduction ‘of p; and p®; in having
the transverse band between the ears divided into two separate
triangular lobes ; in having the proximal half of the forearm
densely haired; in the proportionately shorter hand; in the
larger foot, short calcar, short postcaudal imterfemoral, and
ligiter-coloured underside of the body.
4. Micronycteris hirsuta, Ptrs.
1869, Schizostoma hirsutum, Peters, MB. Akad. Berlin, p. 397.—Type:
3 ad., in alcohol ; locality unknown; Paris Museum.
Skull—Similar in shape to the skull of M. megalotis and
M. minuta, but much larger, and brain-case less vaulted and
raised above the facial region, the profile-line, from the
uppermost point of the brain-case to the nasals, therefore
less concave.
Teeth. — Cutting-blade of # markedly less compressed
antero-posteriorly than in MM. mega/otis and minuta. Upper
premolars as in M. megalotis. Almost the same is the case
with the lower premolars : p» slightly higher than p,, which
is slightly higher than p,.
Ears.—Proportionate size as in M. megalotis and minuta ;
number of cross-ridges 13-14, covering a space of about
1] mm.
Transverse band between ears, in both sexes, very low,
straight (not higher in the middle), and without median
notch. There seems to be no frontal groove (the two
specimens examined of this very rare bat are in a bad state
of preservation).
Ce
Mr. K. Andersen on the Bats of the
Nose-leaves.—Lancet proportionately shorter, its extreme
length only a little longer than its width at base.
Wings.—Wing-structure almost precisely as in M. mega-
lotis, the only noteworthy difference being the somewhat
shorter metacarpals.
Forearm haired almost to the extremity. Membranes
inserted very nearly on the ankles. Forearm 435-45 mm.
Calcar.—Slightly longer than the foot.
Specimens examined.—Pozo Azul, Costa Rica, 200 m.
(g ad., 9 ad.). One skull.
Range. an yet known from Costa Rica only.
Remarks.—Vhe large size of M. hirsuta prevents its con-
fusion with any other species of the genus.
II. Grypenonycrerts, Thos.
1896. Glyphonycteris, Oldfield Thomas, Ann. & Mag. N. H. (6) xviii.
pp. 3801-2; Oct. 1, 1896.—Type: Glyphonycteris sylvestris.
Skull.— Facial portion, immediately in front of orbits, very
conspicuously inflated. Anterior nasal openings more hori-
zoutal in position than in Micronycteris, directed chiefly
upwards. Basioccipital pits, antero-internally to cochlee,
very deep.
Dentition—? very pronouncedly chisel-shaped, its cutting-
blade broad from side to side, extremely thin antero-poste-
riorly. Canines short, their antero-posterior basal Boh:
equal to their vertical diameter. Inner cingulum of
developed into a conspicuous rather broad “heel” ; tip of
the principal cusp of p*® anterior in position, situated in a
vertical line through the front end of the base of the pre-
molar ; antero-posterior basal much longer than vertical
diameter. Inner margin of the cingulum of p* conver; no
distinct “cusp 6.”
Ears —Not conjoimed by a transverse band across the
head. Outer margin of ear-conch distinctly concave in its
upper half.
Chin —As in Micronycteris.
Wings.—Third and fifth metacarpal subequal in length,
fourth the shortest. Second phalanx of third digit from 14
to 1} the length of the first phalanx.
A comparison with M. megalotis and hirsuta = M. minuta
the hand is peculiarly shorteued) will readily show how this
modification of the wing-structure has been effected (see
wing-indices, below, p. 65) :-—In Glyphonycteris the fourth
metacarpal has, very nearly, the same proportionate length
as in M. hirsuta, whereas the fifth and, still more, the third
Genera Micronycteris and Glyphonycteris. 59
have increased in length, making as a total result the fifth
and third metacarpal subequal, the fourth the shortest. In
Glyphonycteris the first phalanx of the third digit is
shortened, the second correspondingly lengthened ; in other
words, the joint between the two phalanges has been removed
in proximal direction (compare wing-indices of G/ypho-
nycteris and M. megalotis). ‘The joint between the first and
second phalanx of the fourth digit has been similarly removed
in proximal direction, making the latter phalanx decidedly
longer than the former.
Species.—The genus was’ based on G. sylvestris. Au
examination of the British Museum material has convinced
me that Peters’s M. Behni is a Glyphonycteris; the same is
probably the case with Dobson's M. brachyotis.
Range.—From Brazil (Matto Grosso) and Peru through
Guiana to Central America.
1. Glyphonycteris Behni, Ptrs.
1865. Schizustoma Behnii, Peters, MB. Akad. Berlin, pp. 505-8.—
Type: @ ad., in alcohol; Cuyaba, Brazil.
Skuli and teeth.—Sce the diagnosis of the genus.
Ears.—Short ; not reaching the tip of the muzzle when
laid forwards. Cross-strie faint, rather ill-defined ; number
about 10 (?), covering a space of about 9 mm.
Nose-leaves.—Essentially as in M. megalotis, the extreme
length of the lancet being equal to about 15 its width at
base.
Wings.—Forearm practically naked. Membranes from
the ankles. Length of forearm about 45-47 mm.
Calcar.—Shorter than the foot and very nearly equal to
half the length of the lower leg.
Tail and interfemoral.—The postcaudal interfemoral seems
to be equal to the length of the tail (the available specimens
are somewhat damaged).
Specimens examined.—River Cosnipata, District of Puno,
S.E. Peru (2, skins in alcohol). One skull.
Range.—As yet only recorded from Cuyaba (Matto Grosso)
and Cosnipata.

1896. Glyphonycteris sylvestris, Oldfield Thomas, Ann. & Mag. IN: HT:
(6) xviii. pp. 302-3; Oct. 1, 1896.—Type: ¢_ad., skin; Miravalles,
Costa Rica; British Museum (no. 96. 10. 1. 2).
Specific characters—Similar to G. Behni, but smaller.
See the measurements below, pp. 614-65.
60 Mr. K. Andersen on the Buts of the
Colour.—Hairs of upperside with four alternating rings of
dark brown and whitish; the extreme base, next to the skin,
white ; a broad ring of blackish brown; a broad ring of
white or yellowish white; narrow tips of hairs approaching
clove-brown. Fur of underside dark brown at base, greyish
drab at tip.
Range.—As yet only known from the type specimen,
obtained at Miravalles, Costa Rica.
3. Glyphonycteris brachyotis, Dobson.
1879 *. Schizostoma brachyote, Dobson, P. Z.S. 1878, p. 880.—Type
from Cayenne; Paris Museuw ; the only specimen on record.
The species is known to me from the published account
only.
Dobson did not examine the skull; the dentition is not
described in detail; the presence or absence of a transverse
band between the ears is not mentioned, nor is there any
accurate information as to the proportionate length of the
metacarpals.
Notwithstanding these deficiencies in the description of the
species, I think there can be little doubt that it is a member
of the genus Glyphonycteris :—(1) The cusp of the first upper
premolar (p®) is, aecording to Dobson, “very oblique,
touching the canine” ; this probably means that the tooth is
remarkably long in antero-posterior direction, and the cusp
situated at the front eud of the tooth, as in Glyphonycteris :
(2) the ears (“much shorter than head,’ tip ‘ obtusely
pointed”) are as in G Behni, not as in a Micronycteris :
(3) Dobson’s omission of any reference to the ear-band is
probably an indication that it is absent: (4) the second
phalanx of the third digit is much longer than the first
phalanx, also one of the features of Glyphonycteris iu contra-
distinction to Micronycteris: (5) unfortunately Dobson only
gives measurements of the third and fifth digits, but the
wing-indices, as derived from these measurements, are more
in accordance with those of Glyphonycteris than with those
of Micronycteris.
G brachyotis seems to be precisely of the same size as
G. sylvestris, but the calcar is stated to be longer than the
foot.
Range.—Cayenne.

Nomada (Xanthidium) subrutila, Lovell & CkIl., 1905.
Boulder, Colorado, at flowers of Pulsatilla hirsutissima,
one ¢, May 1, 1906 (Marie Gill).
This species was previously known by a single male taken
in Maine. The Colorado example has the flagellum duller
and distinctly deuticulate, and the b. n. passes a short distance
basad of the t.-m., but they otherwise agree. In my table
of Rocky Mountain species the insect runs to N. civilis, from
which it is easily known by the denticulate flagellum and
other characters. It is ncarest to N. lutevloides, “Robertson,
and it is not unlikely that it will prove to be only sub-
specifically distinct.
Nomada pulsatille, sp. 0.
? —Length about 7} mm.
Red and _ black, mith no yellow anywhere ; mandibles
simple ; head broad, facial quadrangle conspicuous'y broader
than long; head red, with the cheeks posteriorly, a large
patch enclosing the ocelli, the middle of front (enclosing no
red spot), the region about antennae, and a broad mark
extending halfway down sides of clypeus all black; the
supraclypeal area is black, with a red spot; hair of head and
thorax above fuscous, black on scutellum and scape; that on
metathorax, pleura, and cheeks pallid; antennz long, en-
tirely ferruginous, third joint about as long as fourth;
mesothorax coarsely rugoso-punctate, red, with a broad
median black stripe ; “scutellum red, flattish, aud not

Hab. Boulder, Colorado, at flowers of Pulsatilla hirsu-
tissima, April 20, 1906 (Cockerell).
In the table of Rocky Mountain species (Bull. 94, Colo.
Exp. Sta.) this runs to 68, and runs out because the abdomen
has no yellow spots. From N. Packardiella it differs by the
much broader abdomen, without yellow spots or distinct
black bands, the golden pile on the entirely red hind tibiz,
&e. From N. Clarkii it differs by its smaller size and the
details of the coloration of the abdomen, but the two are
closely allied. From WN. /atifrons it differs by the broad
abdomen &c. It is also related to N. valida.
There is quite a strong superficial resemblance (as seen
without a lens) to N. polyacantha, Perez, from Barbary, but
that species has the b. n. meeting t.-m., the mesothorax

lissima, April 20, 1905 (IVY. P. Cockerell).
I thought at first that this was the male of N. pulsatille,
but there are so many differences that it seems best to regard
it as distinct. In the table of Rocky Mountain species it
runs to 62, but runs out because of the rather small size
and red on scutellum. It is known from WN. vicinalis by its
smaller size, total absence of yellow on thorax, &c. ‘There
seems to be some affinity with N, denticulata, Rob.

Mandibles simple; head and thorax red, with black
markings and no yellow ; abdomen narrow, light red, with a
sericeous surface, and a round cream-coloured spot on each
side of second segment, but no other light markings. Head
broad, face conspicuously broader above than below ; Jabrum
with a small tubercle; front above antenne broadly black,
but no black at sides of clypeus; ocelli on a small transverse
black area; cheeks posteriorly black ; antenne long, all red,
except that the end of scape is black behind; third joint
conspicuously shorter than fourth, but still much over half
its length; hair of head and thorax very scanty above, but
snow-white patches showing on cheeks beneath, lower part
of pleura, metathorax, &c. ; mesothorax with a median black
band, the red on each side of which is deeply incised by
black auteriorly, producing the appearance of flames;
scutellum and metathorax red, the latter with a rather weak
black band; pleura and tubercles red; tegule light red.
Wings dusky, especially at apex, with the usual light area;

Hab. N. Yakima, Washington State, May 15, 1903
(Eldred Jenne).
From Mr. Melander, with his no. 18. In the table of
Rocky Mountain species this runs to 70, but is quite distinct
from N. Sayi. In Robertson’s table it runs to 4 (N. Cres-
sonu and Sayi), but is not identical with the species there
indicated. The insect reminds one strongly of some of the
species of Gnathias.
Also at N. Yakima, but on June 5, Mr. Jenne took
Nomada erythrochroa, Ckll., of which only one specimen
(from Pasco) was previously known.
Centris Morsei marginata (Fox).
The Centris marginata of Fox is evidently only a variety
of Morsei, as Mr. Fox suspected. The original type, which
is before me, shows that the abdomen is not bare, as Fox
states, but is pruinose-pubescent exactly as in Morsei. The
lack of pubescence on the middle of the thorax is due to
abrasion. The fourth antennal joint is red beneath. A
second specimen of this form has been taken by Dr. F. H.
Snow at the San Bernardino Ranch, Douglas, Arizona,
3750 feet, August.
Centris atripes, Mocsary.
Renewed study convinces me that C. Fori, Friese, must
fall as a synonym of C. atripes. The species is to be added
to the fauna of Arizona, as Dr. F. H. Snow took two males
at the San Bernardino Ranch in August. At the same
locality Dr. Snow took Protowea gloriosa (Fox), also new to
Arizona.

palpi with first joimt more than twice length of second ;
maxillary palpi long and slender. [ace densely covered
with ‘silky pale fulvous hair; eyes dark sea-green; meso-

Tetralonia Edwardsii vagabunda, CkIl.
Tn my original account of this bee (Trans. Amer. Ent. Soc.
xxx. p. 95) I stated that it was from flowers of Onosmodium.
During my absence in June 1905 my wife collected a series
of bees from the flowers of a plant which she took to be
Phacelia, and so labelled them. I did not see the plant in
flower, but later in the year we found what appeared to be
the same, with abundant fruit, and it was Onosmodium caro-
linianum. This year we have found the original plant in
flower, and it is Phacelia heterophylla, Pursh; but growing
in the same places, and almost exactly similar in foliage and
manner of growth, is the Onosmodium. Such resemblance
between two plants growing under the same conditions, but
of different families and having quite different flowers, is
interesting.
The following bees were taken by my wife from flowers of
Phacelia heterophylla at Boulder :—Halictus meliloti, Ckll.,
Dialictus anomalus (Rob.), Alcidamea simplex (Cresson),°
Megachile brevis, Say, Tetralonia Edwardsti vagabunda, Ck\l.,
Ceratina nanula, Ckll., and C. neomezicana, Ckll.
At Ward, Colorado (9000 feet), a Phacelia closely allied
to heterophylla was found in quantity. It was recorded at
the time as P. circinata, following Coulter’s manual; but it
is not the true species of that name, and I suppose that it
must belong to P. alpina, Rydberg, 1900. It proved very
attractive to bees, and the following were collected on it at
Ward in July by my wife and myself :—Colletes phacelie,
Ckll., Anthidium emarginatum, Say, A. conspicuum, Cress.,
Osmia propinqua, Cress., Monumetha argentifrons, Cress.,
Megachile latimanus, Say, M. vidua, Smith, Bombus Ed-
wardsii, Cress., var., B. iridis phacelie, Ckll.
TuyGater, Holmberg.
In Trans. Amer. Ent. Soc, xxxii. p. 115, I called attention
to the identity of Thygater with Macroglossapis, and gave
reasons for supposing that the latter had priority. I learn
On new Species of Acreeidee from Uganda, 75
from Mr. J. C. Crawford, however, that Holmberg, in Actes
Acad. Cordoba, v. p. 1383 (1884), remarked that Tetralonia
- terminata, Smith, had only three joints to the maxillary
palpi, and might form a new genus Zhygater. ‘This slight
reference has been overlooked by all subsequent authors, but
I think it will hold the name, giving Thygater priority.
The genus consists of the following known species :—
Thyygater terminata (Sm.), 7. chrysophora, NWolmbg.,
T. analis (Lep.), T. albilabris (Cress.), 1’. montezuma (Cress.),
7’. modesta (Sm.), 7. rubricata (Sm.).
Bombus Kohli, n. 0,
Bombus carbonarius, Handlirsch, Ann. naturh, Hofmus. Wien, 1888,
p. 242. (S. America.)
The name is changed because of B. carbonarius, Menge,
1856, from Prussian amber. As Friese has already named
a Bombus after Dr. Handlirsch, the present insect may bear
the name of another distinguished naturalist of Vienna, I
possess the species from Villa Encarnacion, Paraguay,
collected by Mr. Schrottky. Dr. Handlirsch, to whom I
wrote concerning the preoccupation of carbonarius, replied
that he did not himself intend to propose a substitute.

punctures. The first abdominal segment is sparsely
punctured,

XVIII.—Notes on the Genus Hematopota of the Family
Tabanidee in the British Museum Collection. By Gertrupe
Ricarpo.
[Plates III.-VI.}
Hanmarorora, Meigen.
Hematopota, Meig., Iliger’s Mag. ii. 267. 40 (1803).
This genus is readily distinguished by the peculiar markings
of the wings, but the species are not easy to describe.
Loew gives what he considers good characteristics for the
distinction of the species in his Dipt. Siidafrik., relying on
the shape of the head, the position, shape, and size of the
paired spots, and the absence or presence of the unpaired
spot, and, in alesser degree, on the markings on the face ;
the shape of the antennz he considers a doubtful character,
of the Family Tabanide. 95
especially as to the incrassate or cylindrical first joint, but
the legs afford good characteristics. He considers the wings
very difficult to describe, but gives some of the chief points.
To the above I am inclined to add the shape and size of the
frontal callus as useful, the general shape of the antenne
(which vary consider ably), and to rely upon the presence or
absence of rings on the legs and the possession of a white
base to the tibiz.
Though the markings of the wings may be relied upon as
a rule, there is no doubt that they vary slightly in different
specimens of one species, as in the shape or length of the
apical band and in the presence or absence of the pale
markings at the openings of the cells. The rings on the
legs also are not to be implicitly relied upon, a second faint
pale ring sometimes appearing in a species which, as a rule,
has only one ring ; this occurs chiefly on the fore tibize.
My tables are drawn up only for the females.
Those species marked with an asterisk denote there are
specimens of them in the British Museum collection.
Through the kindness of Mr. J. A. Gerald Strickland, who
has devoted a great deal of time and trouble to the work, I am
enabled to give photographs of the wings of all the new
species but one, of four of Bigot’s types, and of two of
Walker’s types, which it is hoped will be of assistance in the
identification of the species and will save the wearisome
labour of reading through long descriptions of the intricate
markings of the wings. The actual colouring of the wings
is given in the letterpress as nearly as possible as it strikes
the naked eye. ‘The magnification is approximately ten
diameters.
The species described by Wiedemann as Hematopota
coarctata (Auss. zweifl. Ins. p. 578) from South Amercia does
not belong to this genus, but to Acanthocera, Macq., as
surmised by Bigot (Bull. Soc. Zool. Fr. xvi. p. 74, 1890),
and is included in my table of the latter genus in Ann. &
Mag. Nat. Hist. xiv. (7) p. 363 (1904). This genus does
not occur in South America.

antennee is grey, not black.
Hematopota variegata, 3 ¢ , Fabr.
Three females from Hyeres, 4. ix. 93 (Yerbury), 93. 123.
Two females from Castel Fusano, Ostea, Italy (Dr. Sambon),
1901. 99.
Two females from Boscoff, Brittany, 6, ix. 92 (O. Thomas),

Two females from Kanea, Crete, first week in May, 1904
(Miss M. D. Bates), 1905. 25; and others from Morea and
Italy.
This species, originally described from a specimen from
Tangiers, must be very nearly related to, if not identical with,
of the Family Tabanide, Qi
HT, italica, both species being distinguished by the cylin-
drical long first joint of the antenne. The characters given
in the table to distinguish the two species are taken trom
Schiner and other authorities, but will probably not prove
satisfactory, judging from the material in the National
Collection, which, however, is too poor to throw further light
on the question.
Hematopota italica, 8 2, Meigen.
One female from Nicosia, Cyprus (Miss M. D. Bates),
1903. 64.
One female from France.
Mik, in ‘ Fauna Hernstein,’ Becker, iii. p. 515 (1886),
distinguishes this species from H. pluvialis by the cylin-
drical first joint of the antennze, which is as long as the third
joint and hardly thicker, and adds that the grey tomentum
covering it is so thick that only here and there is the shining
black colour to be seen through.
Hematopota pluvialis, 8 9, Linn.
Specimens are in the Brit. Mus. Coll. from Norway,
Leenane, Co. Galway, Gloucestershire, Avon Valley, Boppard
on the Rhine, Alps, Spain, The Hague, Italy, and France.
It is distinguished from H. italica by its thickened first
antennal joint, which is distinctly wider in the middle and
much shorter than the third joint, and the bright black
colour is not obscured by grey pubescence.
The H. tristis, 2, Bigot, type, with the exception of the
more yellow colour of the middle and posterior femora, is
identical with this common European species; the type
comes from Japan.
Hematopota lusitanica, 2 , Guérin.

A large blackish species, evidently distinct from H. crassi-
cornis ; but at present the only distinction I can give to
separate them is the larger size of the above.

98 Miss G. Ricardo on the Genus Hematopota
One female from Glen Avon, S. Banffshire (W. R. O.-
Grant), 93. 95.
The male of this species may easily be distinguished by
the wholly black colour of the antennz and by the very thick
first joint.
The female is less easily distinguished from that of
H. pluvialis, but Strobl, in Mittheil. Ver. Steierm. 1892,
xviii. (1893), recognizes it by the extraordinarily thick
first jomt, which is short, stout, and not constricted near the
tip ; only at its base is it obscured by grey tomentum ; the
shining black band above the antenne is narrower and not
produced above in the centre ; the third joint of the antenne
is only red at the base. In H. pluvialis tle first joint is much
slenderer, covered with grey tomentum to the middle and
strongly constricted before the tip; the red colour on the
third joimt is more extended, the black band broader,
produced in the centre as a triangle.
The four males collected by me form part of a series of
two dozen or so caught in one week, resting on the highest
and sunniest parts of a stone wall round an unoccupied
farmyard ; no females were to be seen. I was not successful
in discovering their breeding-place.
Nearctic Region.
There are only two species known in N. America, both
said to be fairly common. There was a specimen in the
British Museum Collection labelled “N. America” and
placed under H. punctulata; it is apparently a specimen of
Hi. variegata, and certainly does not agree with the description
of either of the N.-American species ; the locality-label is
probably incorrect.

Ethiopian Region.
The described species of Hematopota from this region
number nineteen, counting H. ruficornis, &, Macq., and
H. ruficornis, §, Walker, as two distinct species, and
H, dorsalis, Loew, as a synonym of H. decora, Wk. ;
of the Family Tabanide. 99
thirteen of these are from South Africa, two from West
Africa, and five from East Africa. Ten new species are
described in this paper, of which five come from Uganda,
four from East Africa, and one from the Transvaal, bringing
up the total of described species to thirty. Loew’s Dipt.
Siidafrik. should be consulted for species from South Africa.
The character given in the table of the first joint of the
antennz as incrassate or not incrassate should not be
regarded as absolute, as it is difficult in some cases to decide
under which head a species should be placed. I have inter-
preted incrassate after Mik’s definition (‘ Fauna Hernstein,’
Becker, iii. p. 515, 1886), viz. when the first joint is
elliptical in shape, that is distinctly widened in the middle
looked at from above, it is incrassate as distinguished from
simply cylindrical or not incrassate. I have not seen the
type of H. inappendiculata, ¢ , Bigot.

nine other females.
These were collected and sent by Lt.-Col. Bruce to the
British Museum (Natural History) in a box with tsetse-flies
and other Tabanidz.
A dark hairy species; face with long white pubescence ;
the grey spots on the abdomen large and prominent, appearing
at first sight as grey stripes.
Face greyish, with long white hairs ; some brown colour
appears on the sides, but there are no black spots. Palpi

sate, with long black pubescence; the second joint round
with black hairs; the third wide, rather short, black at its
extreme apex. Frontal callus broad, black, shining, barely
reaching the eyes on its anterior border, receding from them
entirely on the posterior border, which is straight ; the spot
between the antenne black, being a continuation of the
callus ; brown rings round the antenn; the paired spots
small, black, not reaching the eyes; the forehead yellowish
brown near the callus, darker on the vertex. Thorax brown,
with three yellowish-brown linear stripes; a large oblong
spot at the suture on each side-stripe and another one at the
base of each stripe ; sides of thorax grey, the pubescence on
the dorsum spare and short, of a pale yellow colour, on the
sides with long black and then white hairs. Scutellum
brown, with pale yellow pubescence. Abdomen dark brown,
with large, irregular-shaped, grey spots on each side, almost
reaching the anterior border of each segment, but not the
posterior border; the posterior borders of the segments of
the same colour, widest in the middle, the sides partly grey ;
underside greyish. Legs yellow and brown, the femora
yellow with white pubescence, which is thickest on the fore
femora ; all the tibiae have two yellow rings; the tarsi are
darker on the apical half of the joints; the tibie and tarsi
with black pubescence. Wings greyish, with yellowish-
brown stigma and veins, the pale markings fairly distinct,
the apical band short, single.
Length 8 mm.
In some of the specimens the paired spots are larger and
reach the eyes.
Pl. III. fig. 1, type (female).
Hematopota ruficornis, 9 , Walker.
Type, 68. 4 (Saunders), Natal.
One female from Cape Town (H. A. Spencer), 91. 29.
The type is a well-preserved specimen.
The species is distinguished from H. hieroglyphica, Gerst.,
by the characteristics mentioned in the table, and also by
the presence of spots on the face, whereas they are appa-
reutly absent in Gersticker’s species, and the transverse
callus is shining red-brown, not pitchy black. From
H. meteorica, Corti, it is distinguished by the absence of any
large brown longitudinal band on the underside of the
abdomen, and only the extreme tip of the antenne is black.
The following redescription may be found useful :—
A red-brown species, with distinct grey spots on the
abdomen and testaceous antenne.
of the Family Tabanide. 103
Face grey; the spots under the antenne are red rather
than black, as is also the transverse stripe, which is in-
distinct and broken up into red dot-like spots. Palpi reddish,
with dense black pubescence above and some grey hairs
below. Antenne rather long, the first joint light yellow,
cylindrical, but not very slender, with black pubescence ; the
second the same colour, with similar pubescence; the third
reddish, only the last divisions black, a little longer than the
first two joints together. Frontal callus the same colour as
the first antennal joint, slightly lunate in front, very slightly
sinuous on the posterior border, narrow, reaching the eyes ;
there is a faint brown double spot between the antennz ;
the paired spots are brown, large, touching the eyes, the
unpaired spot nearly as large, brown; the forehead yellowish
brown, with grey pubescence. Thorax red-brown, with
narrow grey stripes, the outer ones only reaching the suture
and ending in the usual spots; sides of thorax and breast
greyish; scutellum yellow-brown, with grey pubescence.
Abdomen yellow-brown, darker at the apex, the spots on
the sides of the segments very distinct and large, the median
ones indistinct; the sides of the first three segments are
grey, also the posterior borders of the segments ; the pubes-
cence is chiefly grey ; the underside of abdomen faint red,
with grey tomentum and pubescence. Legs yellowish, the
rings on the middle and posterior legs dark brown ; the
tarsi black, as are also the fore tibiz on the apical haif.
Wings greyish brown, the white markings conspicuous,
especially so at the opening of the fifth posterior cell; the
apical band sinuous, single; veins yellowish brown ; there is
a distinct ocellus above the brown stigma; all the posterior
cells except the fourth with clear margins, that of the fifth
being the largest.
Length 9 mm.
Pl. ILI. fig. 2, type (female).
A smaller specimen from Cape Town seems identical. It
hardly seems probable that the male described by Macquart
as H. ruficornis is identical with the above, as suggested by
Walker; Macquart describes his species as blackish, and
_says the third joint of the antennz is a little shorter than
the first joint ; the locality is Port Natal.
Hematopota nigrescens, 2, sp. n.
Type (female), Altri-iga, Mawe, B. E. Africa (C. S. Betton),
1900. 35, 13. 11.—4. v. 99.
A small black-grey species with yellow antenne and yellow
legs ; the first joint of the antenne short.
104 Miss G. Ricardo on the Genus Hematopota
Face grey, with no black spots; a narrow brown stripe
between the antennze and the eyes, bordering the frontal
callus. Palpi the same colour, with black pubescence.
Frontal callus shining black, narrow, bordering the antennz
closely, leaving only a small triangular black spot between
the antenne, reaching the eyes, not produced in the middle.
Antenne light yellow; the first joint short, cylindrical, the
second round, short, with no cup-like prolongation above,
the third with the basal annulation not very wide; there are
ong black hairs on the first two joints. Forehead wide,
greyish, with the dark ground-colour apparent, becoming
shining on the vertex ; the paired black spots are small, not
touching the eyes; there is no sign of the unpaired black
spot. Thorax black, with three faint grey stripes and grey
tomentum, which latter covers the scutellum. Abdomen
black, with a well-marked series of hoary-grey undefined spots
on each side; the hind margins of the segments are also
grey. Legs the same colour as the antenne; the tarsi
darker ; the rings of the middle and posterior tibiz are
faintly outlined by a dark ring of colour, but even this is not
apparent on the fore tibiz. Wings greyish, the rosettes of
light colour, fairly distinct ; the apical sinuous band is double ;
stigma and veins yellowish brown.
Length 8 mm.
Pl. III. fig. 3, type (female).
It was not possible to get a very satisfactory photograph
of the wing, owing to its imperfect condition.
Hematopota longa, 2 , sp. n.
Type (female), Nyasaland, Nov. 1892 (H. H. Johnston),

Lake Nyasa, 3000 feet, 29. 1. 94 (R. Crawshay), 98. 81.
A small black species, distinguished by the long cylin-
drical first joint of the yellow antenne.
Face grey, with two black spots in the centre, not con-
tiguous ; the usual stripe is almost resolved into a large spot
bordering on the eyes and small punctuated spots. Palpi
yellowish, with white hairs at the base and black hairs beyond.
Antenne light yellow, the third joint darker on its apical
half ; the first joint long and slender, together with the second
nearly as long as the third joint; the second short, with
tuft-hke black hairs below and above on its upper edge.
Frontal callus black, shining, in front Iunate, with two
black spots proceeding from it between the antennex; the

hind border somewhat sinuous; the paired spots large,
touching the eyes, the unpaired spot small and indistinct.
Forehead brownish, with grey tomentum forming a broad
arrow on the vertex (the arrow-like shape is only distinct on
the type). Thorax brown-black, rather shining, with grey
stripes. Abdomen brownish black, the hind borders of the
segments greyish; there are indistinct grey spots on the
hind segments. Legs brownish, the usual lighter rings and
the base of the metatarsi yellow, the tarsi black, the fore
tibiz slightly dilated. Wings brown, with the rosettes of
light colour clearly marked ; the apical sinuous line broad
and single, the posterior cells usually with light colour on
the outer border; stigma and veins yellowish brown.

Hematopota obscura, g ? , Loew.
Two females from Karkloof and one female from Port
Natal seem to agree with the description of the female given
by Loew; the spots on the abdomen are hardly visible on
one of the specimens.
Hematopota ugande, 2, sp. n.
Type (female) and nine other females from Uganda
(Lt.-Col. Bruce), 1903. 206.
This species is nearly allied to H. vittata, Loew, but is
distinguished from it, firstly, by the absence of the black
band on upper part of face; secondly, by the broader frontal
callus produced to a point on the posterior border;
thirdly, by the shape of the antenne, which are longer and
more slender and the first joint is less incrassate; and
fourthly, by the absence of the unpaired black spot on the
forehead. From dH. distincta, sp. n., it is easily distin-
guished by the difference in the wings, its smaller and less
robust appearance, and its lighter colouring.
Face brownish, covered with grey tomentum, the brown
colour appearing as the usual spots and as the transverse
stripe: the spare pubescence is yellowish. Palpi faint red,
with grey tomentum and short black pubescence. Antenne
yellowish brown, with some grey tomentum, the last divisions
of the third joint deep black; the first joint slightly incras-
sate, the second short, both with black pubescence, the third
rather long and slender. Forehead brown, yellowish at the
sides and round the spots. Frontal callus reddish brown,
shining (in some of the other specimens it is darker, almost
106 Miss G. Ricardo on the Genus Ueematopota
black), broad, produced on its anterior border; the paired
spots large, not reaching the eyes, deep brown ; the unpaired
spot is not apparent. Thorax brown, with three narrow
yellowish stripes, the central one expanding beyond the
suture into a broad median stripe with spots at its base, the
side ones end in the usual spots, sides yellowish; or the
thorax might be described as yellowish brown with three
brown stripes, the middle one divided by a yellow line and
terminating at the suture. Scutellum brown, with a central
yellowish stripe. Abdomen brownish, yellower at the base
and on the sides, where the yellow appears as large irregular
spots, and the posterior borders of the segments are yellow
with short yellow pubescence ; the underside greyish brown.
Legs reddish brown with yellow rings; the fore tibiz only
yellow at the base. Wings brown, with the rosettes more
distinctly marked than in H. distincta, often lighter in the
centre; veins brown; stigma dark brown; apical band
single; the blotch on the apical line in the type is not
always present, and may perhaps be accidental, due to a loss
of colouring-matter.
Length 10 mm.
Pl. III. fig. 5, type (female).
Hematopota distincta, ? , sp. 1.
Type (female) from Plateau of Zomba, Nyasaland (A.
Sharp), 97. 46; one female from Kasungu Mt., Nyika,
Nyasaland, 4. ii. 96 (R. Crawshay), 98. 81; one female,
British East Africa (C. S. Betton), 1901. 319.
A well-marked distinct species, the thoracic markings
allied to those of H. vittata. In colour dark brown, the
scutellum yellowish brown, the legs with the usual white or
yellow rings.
Face reddish, with grey tomentum; no black spots and
only a trace of the transverse stripe. Palpi rather long,
yellowish red, with black hairs and some white hairs below.
Antennz brown-black, dull red at the base of the first and
third joints, the first only shghtly incrassate, and with the
second joint covered with black pubescence, the last annula-
tions of the third joint black. Forehead reddish brown, the
froutal callus and paired spots darker brown; the callus
shining, broad, reaching the eyes, lunate on the posterior,
almost straight on the anterior border; the spots between the
antenne black; the unpaired spot small, joimed to a dark
median spot on the vertex. ‘Thorax brown-black, the sides
reddish grey; the stripes narrow, grey, the median one not
very distinct, prolonged into an oblong spot with a wide
of the Family Tabanide. 107
base, the outer ones ending in small spots. Scutellum
yellowish brown, with very distinct grey tomentum on the
anterior border. Abdomen brown, with yellowish borders
to the segments and fairly distinct grey spots on each side
of every segment; the underside brown, with faint yellow
borders and with grey tomentum. Legs dark brown, the
rings light yellow; the fore legs only yellow at the base of
the tibie. Wings large, dark brownish ; the dark markings
give many of the veins the appearance of being shaded ; the
rosettes are fairly distinct, the apical sinuous line single,
concave, short, only reaching just beyond the anterior fork
of the third vein.
Length 11 mm.
Pl. III. fig. 6, type (female).
Hematopota brunnescens, 2? , sp. n.
Type (female) and other females from Catia (Lt.-Col.
Bruce), 1903. 206, and British Central Africa.
A small brown species with grey wings; the upper part of
the face yellow-brown and the first joint of the antennze
rather short.
Face grey, with grey pubescence and no black spots, the
upper part yellowish brown, where it reaches the callus
becoming yellower. Palpi fairly long, grey, with black
pubescence. Antenne yellowish, darker at the extreme apex
and on the upper angle of the base of the third joint ; first
jomt rather short, slightly incrassate, the second small,
both with black pubescence. Frontal callus yellowish brown,
shining, almost straight on both borders, reaching the eyes ;
the paired spots black, reaching the eyes. Forehead reddish
brown, with grey tomentum, most noticeable in contact with
the callus and on the vertex ; some very short black pubes-
cence apparent. Thorax brown, with three yellowish-grey
linear stripes, the middle one very faint, the outer ones
ending at the kase in enlarged spots ; the sides of the thorax
and shoulders grey; scutellum reddish brown, the red
rather apparent, probably owing to the denudation of the
grey tomentum, which is most noticeable on the borders.
Abdomen dark brown, with the posterior borders of the
segments yellowish ; the spots on the sides grey, round; the
underside grey and brown. Legs yellowish brown, some
grey tomentum on the femora and tibiz and some yellow
pubescence on the posterior femora, the usual rings yellowish.
Wings uniformly grey, with faint pale markings; stigma
yellowish brown, veins brown, appendix long.

In other specimens the abdomen is redder, the grey spots
very distinct, and often a grey median line is present ; the
abdomen of type is evidently denuded.
A series from Buruli, Uganda, “in patch of forest on
Lukogo River, halfway between Junda and Kiseliza,” have

Hamatopota bipunctata, 2, sp. n.
Type (female), from Volksrust, Transvaal, 5400 feet,
17. xi. 1903 (Crawshay), and another female from same
locality.
A well-marked species with distinct ocelli and markings
on the brown mottled wings; the black abdomen with two
rows of grey spots. It is nearly related to H. duplicata,
Loew, but the apical band of wing is not double, though at
its end it throws off an indistinct branch; the first joint of
the antennee is incrassate, a point not mentioned by Loew in
regard to his species, and there is no median line on the
abdomen, which, with the very distinct spots on each segment,
distinguishes it from H. duplicata, besides other small
differences.
Face grey, with black pubescence and no spots, the upper
part yellowish brown; above yellowish; below brown, but
broken up in the centre, which is greyish. Palpi long and
slender, stouter at base, tapering to an obtuse point, yellowish,
with grey tomentum and black hairs. Antenne reddish
brown, the basal joint densely covered with grey tomentum,
with long black hairs and a few yellow shorter hairs, stout
and large, in length approaching that of the third joint;
the second joint small, red, with black hairs; the third red,
at the apex blackish, the red basal portion broader. Frontal
callus very inconspicuous, being covered with grey tomentum ;
it is yellowish, small, and narrow, not attaining the eyes,
hardly extending beyond the base of the antennz, straight
on both borders ; the paired spots black, large, reaching the
eyes. Forehead wide, brownish, covered with grey tomentum ;
on the vertex a large heart-shaped brown spot, with a fine
grey median line dividing it into two halves ; the pubescence
of the forehead black, short. Beard white. Thorax blackish
brown, with two interrupted grey stripes and a trace of a
narrow median one; shoulders and sides grey ; the scutellum
of the Family Tabanide. 109
the same colour, with a grey median stripe and grey on the
outer borders. Abdomen black-brown, with distinct large
grey spots on each side, beginning from the first segment
and reaching to the last segment ; the posterior borders grey ;
on the second segment the border is enlarged to a triangular
median spot; traces of similar spots are seen on the other
segments, but they form no distinct median stripe; the very
short pubescence is chiefly black on the dark colouring and
grey on the grey colouring, with the sides thesame. Under-
side brown, with inconspicuous yellow pubescence. Legs
brown, the knees of the femora yellow ; the tibiz with two
yellow rings ; the tarsi brown, the basal joint yellow, brown
at the extreme apex ; the pubescence of the legs black, with
some few white hairs. Wings brown, the extreme base
and fore border lighter, all the rosettes fully formed and
distinct ; the stigma brown; veins brown; the appendix
large.

Hematopota imbrium, ° , Wiedem.
Two specimens in poor preservation labelled “ South
Africa (Dr. Smith),”’ 44. 6, are probably identical with this
species,
Loew remarks that it is difficult to distinguish between this
species and his H. recurrens and H. scutellatus ; the whitish
triangular spots on the median line of the abdomen mentioned
by Wiedemann are not present in his species. Macquart
declares H. imbrium to be a common species in Kaffraria.

Wiedemann’s species; the distinction regarding the wings

the author describes in his species and no median grey line
is apparent on the abdomen.
There are two specimens from the same locality, likewise
badly preserved ; in the wings the light colour is almost
entirely broken up into minute spots; probably they will
prove to be a new species,
Hematopota decora, ?, Walker [H. dorsalis, Loew}.

These specimens have not the stripes of the thorax con-
tinuous as in table i. fig. 33 of Loew’s ‘ Diptera Siidafrika,’
but interrupted at the suture for a space; otherwise they
agree with Loew’s description ; his type came from Caffraria,
S. Africa. The figure of the antenne in his fig. 34 is
evidently incorrect, the first joint being very much incrassate
and the third joint much broader than usual, as noted in the
text.

Hematopota guineensis, 2 , Bigot.
Type (female) from Abyssinia.
This species was first named H. cordigera, but was changed
to the above name by the author, cordigera bemg already
used for a species from Asia. The type was described with
the antennz incomplete, only the first two joints remaining ;
these are cylindrical, yellow in colour. The frontal callus
is pitchy brown, broad, produced on its hind border, almost
straight on the anterior border ; the paired spots large, brown,
reaching the eyes; the unpaired spot is very small and
indistinct ; the spots on the face are brown and the trans-
verse brown stripe is placed on a line with them, nearly
joining them. ‘The thorax is reddish brown, with three
narrow grey stripes, the outer ones ending at the suture in
the usual spots; there are also half-moon spots at the base
of the thorax; scutellum the same colour, with grey
tomentum ; the abdomen is brownish, yellower at the base,
aud the posterior margins of the segments are lighter
coloured. Legs yellowish brown, the fore tarsi somewhat
dilated. Wings brown-grey, the extreme apex clear; veins
and stigma brown ; the apical sinuous line begins below apex,
reaching the posterior branch of the third vein, where it
joins another short band from the anterior branch.

colour apparent at the sides and on the posterior border of
the segments, also as a fine median line, the first segment
being almost wholly grey. The underside brown, grey at
the sides, on which some minute black dots are scattered.
Legs yellowish, the femora with grey tomentum, and some
black pubescence on the tarsi. Wings have a chequered

Oriental Region.
The described species of Hematopota from the Oriental
Region are fourteen in number, given in Wulp’s Cat. Dipt.
S. Asia. As the material in the British Museum (Natural
History) Collection chiefly consists of new species from
India and Ceylon, I have given a separate table for these
and the Bigot types belonging to Mr. Verrall, including one
Fabrician species of which there are specimens in the Collec-
tion and one of Walker’s types from India. Another table,
mostly of the older species, chiefly from the Kast Indies,
including one of Walker’s types, is given as a possible help
to identification.
The six new species described are all from India and
Ceylon.
Through the kindness of Mr. Verrall I have had access to
the Bigot types with the exception of H. cilipes and
H. pachycera. Of the former there is an example in the
British Museum Collection. Of the latter I have no know-
ledge ; it is distinguished, according to the author, by the
antennz being twice as long as the head, with a black
abdomen, two rows of spots and the borders of the segments
indistinctly grey. The author is doubtful whether these two
species should belong to the genus.
H. concentralis, 2, Walker, is not included in the tables,
the type being without a head or wings, and no locality
given.
H. serpentina, Wied., described without a locality, is

XIX.—On Lamellicorn Coleoptera from Portuguese West
Africa, with Descriptions of new Species. By GILBERT J.
ARROW.
THE British Museum collection contains a_ considerable
number of interesting Coleoptera from the little-known region
of Angola and the interigr of Portuguese West Africa. A
few of the Lamellicornia are here described, together with a
new genus and some observations on species previously
known.

This is the largest and most remarkably accoutred species
of its large genus yet known. It is allied to C. Elphenor,
Klug, and C. Anceus, Oliv., and represents in its armature a
great development of that type. The clypeus is relatively a
little less wide than in those species and almost uninterruptedly
curved. It is narrower in the male than in the female
and the thorax is correspondingly contracted in front. In
both sexes the head bears a horn, but without any similarity
between the two. That of the male is over 20 mm. long in
our specimen, compressed laterally so as to be rectangular i in
section for most of its length, but beyond the middle it is
hollowed out on its inner face and the edges of the channel
are strongly dentate. ‘he horn of the female has the form
of a crescent attached by a short footstalk to the front of the
Copris draco, 3 and Q, nat. size.
head. The two extremities are about 8 mm. apart in our
examples and the footstalk about 3mm. long. The thorax
in both sexés is coarsely rugose except for a small median
posterior area, which is moderately punctured. In the male
this median part is strongly humped and divided in front,
where it terminates in three obliquely placed teeth on each
side. The lateral margin in the same sex is furnished at the
middle with a large leaf-like or wing-like process, curving
SJrom Portuguese West Africa. 129
upwards and forwards and tapering to a point. Immediately
behind this the thoracic margin is deeply excised, and between
the wing-like processes and the dorsal hump are deep and
very rugose excavations. In the female the lateral processes
are very slightly and the dorsal hump rather more strongly
indicated. In other respects the sexes are alike. The elytra
are highly polished, with feebly punctured strize, and tlie
pygidium is thinly and shallowly but uniformly punctured.
Catharsius peregrinus, Harold.
We have received this very peculiar species from Bihe and
San Salvador. It is remarkable for its depressed form,
elongate clypens, and the proportionately small development
of its hind body.
Gymnopleurus azureus, Fabr.
Specimens from Bihe, agreeing with the description of
G. olivaceus, Qued., seem to belong to this widely distributed
Fabrician species. G. insidiosus, Péring., is, I believe, also
inseparable from it.

This species is very closely related to C. auspicata, Péring.,
with which it almost exactly agrees in size, sculpture, and
general form. ‘The prothorax, however, is slightly different
in shape. In the male of C. auspicata it is broadest behind,
the sides slightly approximating anteriorly in a sinuous line.
In the new species, on the contrary, there is a slight widening
towards the front and the sides are uniformly curved. The
raised margin is extremely narrow, and not, as in the other
species, widened at its posterior part. ‘The dorsal elevation
does not extend quite so far forward, and exhibits four angu-
lations, the slight outer ones being entirely absent in
C. auspicata. This difference is traceable also in the females.

The unique specimen of this species is rather larger than
the type of IV. nigropiceus, Qued., in M. Oberthiir’s collection,
with which I have kindly been enabled to compare it. Its
thorax is relatively rather shorter and much less constricted
in front. The front angles in that form are very prominent,
but in N. laticollis they are truncated and so each replaced by
two obtuse angles. ‘The front margin is thickened at each
end for a short distance, and at each end of the posterior
margin a right angle is formed by a curved longitudinal
carina about half the length of the thorax. The broad lateral
flange vanishes at about the middle of this carina. In
NV. nigropiceus the posterior carina is continued until it meets
the anterior carina, and the outer flange is narrower and more
sinuated. ‘The two median thoracic interspaces are coarsely
punctured, but scarcely so coarsely as in the allied species,
and the outer spaces, which in that are almost smooth, are
rather sparsely pitted. ‘There are three strong carine on
each elytron, each bordered by finely punctured strize. The
six-jointed abdomen is very coarsely pitted, but less coarsely
than in LV. nigropiceus.
Hybosoride.
Pheochrous dispar, Qued.
Both sexes of this remarkable species, of which the elytra
of the female are shining and those of the male sooty, were
brought from Garenganze.
‘The imperfect female specimen of unknown origin called
Silphodes dubia by Westwood nearly resembles the female of
P. dispar, but is rather smaller, the sides of the prothorax
are rather more curved and the punctures upon its disk rather
less fine.

Type, “ Pachycnema” Dekindti, Nonfried.
Both sexes of this very peculiar insect were collected by
Dr. Welwitsch at Huilla. Herr Nonfried appears to have
described the species from the male alone, the female having
the hind tibiz only slightly swollen and the single hind claw
of normal size. ‘The form of the hind tibie evidently led
him to place it in Pachycnema, with which it has really no
near relationship. Whereas that genus is the type of the
suctorial division of the Hoplinze with membranous ligula,
Areohoplia belongs to the true Hopliine, distinguished by
entirely horny mouth-organs of the usual biting type. Its
most remarkable feature is the form of the clypeus, the outer
margins of which are drawn out into long straight compressed
rods, as in the Cetoniid genus Gnathocera.

This is another member of the African group of Anomalw,
pale in colour, with darker tarsi and tibiz, in which the male
has the larger claw of the front foot only cleft and the female
those of the front and middle feet. The other species of the

of them all, the female being rather larger and more robust
than the male and the puncturation rather stronger.
From specimens in our collection I believe Mr. Péringuey
has been misled in recording the claw-structure of A. repensa
and intrusa, an occurrence which is very liable to happen, as
specimens abnormal in this respect are not uncommon. In
this way I was myself misled into describing the claws of
Nongoma calcarata, Arr., as differing sexually, whereas they
are normally alike.

Hab. Garenganze, Bihe.
Seven specimens of this species are all males. In the
absence of the other sex I should have refrained from
describing it, but for its very well-marked and unusual
colouring. The head and thorax are bright yellow, except
for the hind margin and a roughly triangular patch in each
hind angle of the latter, whica are black. The elytra are
entirely jet-black and shining, their surface rather thickly
punctured. ‘There are no striz, but some of the punctures
form quite indistinct series. The pygidium is closely and
aciculately punctured, reddish testaceous, and generally more
or less infuscate at the sides.
Nannopopillia Damare, Ohaus.
A good series of a very variable insect, which I identify
with Dr. Ohaus’s Damaraland form, was brought from Huilla
by Dr. Welwitsch. Only a few of them show the type of
colouring described by Dr. Ohaus, in which there is a large
yellow stripe upon each elytron. The greater number have
from Portuguese West Africa. 138
the elytra testaceous, but slightly paler in the middle, with
the suture black and a tendency to a darkening round the
scutellum. ‘There is also a variety (male) in which the
elytra are entirely black, and no doubt all intermediates
occur. The notable disparity in breadth between the sexes
given by Dr. Ohaus is not confirmed by our larger series,
nor is there a sexual difference in the thickness of the batry
clothing. ‘The latter is scarcely closer at the sides of the
segments, as stated by Dr. Ohaus.

Hab. Huilla (Dr. Welwitsch).
A small species, rather larger than the South-African
P. Corydon, Oliv., and quite black above. ‘The cephalic
horn of the male is rather slender and a little compressed
laterally, and is represented only by avery slight prominence
in the female. The thoracic excavation in the male is very
small in our only example of that sex and its posterior margin
is not sharply defined.

This is a very distinct species owing to the extremely
smooth and glossy surface of the prothorax and elytra, espe-
cially in the male. Of the four specimens in our collection
the two females are a lighter red colour than the male,
but this difference may not be constant. ‘The male, as is
usually the case in the genus, is shorter and more parallel-
sided than the female. It is also almost devoid of punctures
upon the thorax and elytra. The thorax is only slightly
excavated in front and the hind margin of the cavity is not
at all produced or carinated. In the female the sides of the
thorax are less uniformly curved, there are punctures which
become denser at the front and sides, and the elytra are
obsoletely striate-punctate.
All the males in this and the allied genera have the front
tarsi thickened and their inner claws strongly hooked and
very broad.
The genus Astaborus, which has not hitherto been asso-
ciated with Pycnoschema and in the Munich Catalogue is
widely separated from it, is really a section in which the
thoracic armature has reached its greatest development. As
the number of known species increases it may very possibly
become inseparable from Pycnoschema. 1 have identified
both sexes of Astaborus Antinorti, Gestro, the female of
which has a curved cephalic horn and bitid thoracic process
very much as in the male, but the former is less flattened
and the latter less produced and very strongly punctured all
over. As there can be no doubt that the very nearly related
typical species, A. armatus, Thoms., has a similar female,
the armature of this sex forms the best distinctive character
of Astaborus. There is also a slight elongation of the front
tibiz in the male, a feature which is not found in the known
species of Pycnoschema.
M. Raffray seems to have overlooked the existence of the
latter genus when he described four species nearly related to
its typical forms, which he placed in Astaborus as a new
section of that genus. The two species of Astaborus I have
from Portuguese West Africa, 135
mentioned are the only ones really belonging to it. Of
Pycnoschema seventeen species in all are now known, and
those remaining to be discovered in all parts of Africa are
no doubt very numerous.
Cetoniide.
Sisyraphora cicatricosa, Burm.
Specimens from Huilla and Bihe closely allied to the
South-African S. tomentosa, G. & P., appear to belong to
Burmeistei’s Avnoplochilus cicatricosus, which was attributed
by him to India, but is referred in the Munich Catalogue to
Senegal. It differs from S. tomentosa in the absence of the
pale markings of the upper surface and the existence of
smooth longitudinal ridges upon the elytra. The scutellum,
however, is not very obtuse, as it is described by Burmeister,
and it is rugose except for smooth lateral and median lines.

Long. 10-11 mm.
Hab. Bihe, Pungo Andongo (Dr. Ansorge).
This seems to be an abundant species, as I have seen a
considerable number of it. It is smaller than any other
described species of the genus, and its glabrous upper surface
gives it a very distinctive appearance. It is clothed beneath
with very coarse tawny hairs, but above is smooth and
shining. The thorax is fairly coarsely but not thickly punc-
tured and the elytra are almost devoid of punctures, only a
few very fine ones being traceable upon the broad smooth
coste. The clypeus is not pointed, although the broadly
turned up margin is slightly wider in the middle than at the
sides.

Hab. Bihe, Garenganze.
This form is identical in its general appearance with
D. (Ligyromorphus) rufiventris, Arrow, inhabiting Mashona-
land, but close examination reveals differences which are very
slight but sufficient for their separation. The most easily
recognizable is in the armature of the front tibiz, which 1s
alike in the two sexes, but constantly differs in the Eastern
and Western forms. In D. rufiventris there are two broad
and very blunt teeth, and a third is scarcely indicated. In
D. tridens there are three well-developed teeth, and all are
acutely pointed. ‘The sculpture of the upper surface is rather
less rugose in the Angola species. The punctures upon the
pronotum are coarse and very dense, but are mostly distinct,
not completely coalescing as in the Eastern species, and the
sculpturing of the elytra i is correspondingly rather less indefi-
nite and rugose, producing a rather more shining appearance.
I described this genus as new in 1901, having overlooked
the previous existence of Diploa, which was placed by its
author, Herr Kolbe, in a different subfamily to the genus
Myoderma, with which it is undoubtedly nearly related. I
have not seen Diploa proles, Kolbe, but that insect has a
bidentate front tibia, and is no doubt very closely allied to
D. rufiventris, and possibly identical.
The genus Xiphoscelis no doubt has some affinity to these
forms and should be placed in the Trichiine.
XX.—Descriptions of new Mammals from Mount Ruwenzori.
By OLDFIELD ‘THOMAS.
THE first collection sent home by the members of the
Ruwenzori Expedition contains examples of the following
new species and subspecies. All were collected on Ruwenzort
East, at altitudes from 6000’ to 13,000’,
Mammals from Mount Ruwenzori. 137
1. Rousettus lanosus, sp. n.
A member of the /. collaris group; the limbs thickly
hairy.
Size and general characters about as in Pf. collaris. Fur
loose and shaggy, very abundant, its limits not sharply
defined as in &. collarts ; that on the head about 8 mm. in
length, mixed with a large number of much longer hairs,
attaining over 20 mm. On the back the fur is thick and
woolly, passes out on to the proximal half of the upperside of
the forearms, and is continued thickly down the hind limbs
and the wing-membrane external to them to the ankles, the
feet being also thinly clothed above. Interfemoral thickly
furry above, except just along its posterior margin. Below,
the wings are thinly hairy to a point level with the middle of
the forearm, the hind limbs and interfemoral membrane being
also less thickly haired than on the upper surface. Ears
narrow, rather longer than the muzzle. Palatal ridges as in
LR. collaris.
General colour above bistre-brown, becoming warmer
posteriorly ; head darker. Under surface near broccoli-brown,
but with a yellowish suffusion; some of the longer hairs
quite yellow.
Skull rather more delicately built than in R. collaris, the
bones thinner and lighter, muzzle rather longer and narrower ;
postorbital processes very thin; anterior palatine opening
unusually broad.
Teeth conspicuously smaller throughout, each molar and
premolar slightly shorter and very much narrower than in
the allied species.
Dimensions of the type (measured on the spirit-specimen) :—
Forearm 88 mm.
Head and body 134; tail 16, tail free from membrane 9 ;
head 46 ; ear 23; third finger, metacarpus 60, first phalanx 41,
second phalanx 57; lower leg and foot (c. u.) 62.
Skull: length to tip of nasals 42; basal length 37:5 ;
zygomatic breadth 25; breadth of brain-case 17°4; palate
Jength from anterior palatine foramina 19 ; breadth of pala-
tine foramina 3°4; length of upper tooth-row from front of
canine 14°5; the same below, 16°2; first upper molar
23 Xu.
Hab. Ruwenzori East, at 13,000’.
Type. Adult male (in spirit). B.M. no. 6.7.1.2. Collected
by R. B. Woosnam. Three specimens obtained.
This species is allied to R. collaris, but is at once distin-
guishable from that and every other species by the thick
138 Mr. O. Thomas on new
woolly covering of its hind limbs and its remarkably narrow
molars.
The occurrence of a fruit-bat at such an altitude as 13,000!
is very noteworthy.
2. Crocidura niobe, sp. n.
General proportions of C. maurisca, Thos., with which it
shares the unusual character of the almost entire absence of
long bristles on the tail. Fur about 5mm. long on the back.
General colour dark blackish grey (‘blackish slate”), with
indistinct silvery mottling. Under surface scarcely lighter,
the tips of the hairs brown. Hands and feet pale brown ;
fore claws rather smaller than hind. Tail long, slender, not
incrassated, practically without longer bristles—a few present
on the base only; uniformly blackish above and below.
Skull normal in build, without the peculiar delicacy of that
of C. maurisca; the brain-case low, the muzzle stout and
conical. ‘Teeth as usual, the unicuspids broader than long,
very unlike the narrow slender teeth of C. maurisca.
Dimensions of the type (measured in flesh) :—
Head and body 68 mm.; tail 63; hind foot 13 ; ear 10.
Skull: greatest length (including incisors) 20; greatest
breadth 9:1; length of upper tooth-row 8:2.
Hab. Ruwenzori East, 6000. Another from 7000’.
Type. Female. B.M. no. 6.7. 1.32. Original number 618.
Collected 10th January, 1906, by R. B. Woosnam. Three
specimens.
This shrew may be readily distinguished from C. maurisca,
the only species with its proportions and tail-characters, by
its more plumbeous colour and its broader skull and teeth.
3. Crocidura fumosa montis, subsp. n.
Size and other essential characters as in the C. fumosa of
Mount Kenya, but the fur longer (hairs of back 7:0-7°5 mm.)
and the general colour a dark plumbeous grey, without the
distinct brownish tone so marked in true fumosa. The ends
of the hairs blackish, with a silvery subterminal ring.
Dimensions of the type (measured in flesh) :—
Head and body 77 mm.; tail 61; hind foot 15; ear.11.
Skull: greatest length (including incisors) 22; greatest
breadth 10.
Altitude 12,500’.
Type. Female. B.M. no. 6.7. 1.28. Original number 78.
Collected 16th Feb., 1906, by R. E. Dent. Three specimens,
all from about the same altitude.
Mammals from Mount Ruwenzort. 139
4, Myosorex blarina, sp. n.
A dark short-tailed species with the mole-like appearance
of M. Sclatert talpinus.
Size rather less than in MW. Sclater?. Fur thick and mole-
like; hairs of back about 8 mm, in length ; a number of inter-
spersed longer hairs on the rump attaining 12-13 mm.
General colour blackish brown, slightly iridescent, very much
as in M. Sclatert talpinus; under surface scarcely lighter,
more smoky brown than in ta/pinus. Hands, feet, and tail
blackish, the anterior claws very large. ars very short,
quite hidden in the fur.
Skull stout and heavily built—compared with that of
M. Sclateri it is smaller, shorter in the muzzle, but propor-
tionally broader, the imterorbital region and brain-case as
broad as in the larger species.
Teeth rather small throughout, the anterior incisors particu-
larly delicate ; relative proportions of the unicuspids as in
M. Sclater?, the minute posterior one about one tenth the size
of the second, which is half the size of the third, the latter
being about three fourths the size of the first.
Dimensions of the type (measured in the flesh) :—
Head and body 74 inm.; tail 42; hind foot 14; ear 7.
Skull: condylo-basal length 22-1; basal length 19°6 ;
anterior breadth 7; interorbital breadth 5°5; greatest breadth
across brain-case 12; length of upper tooth-series 10°8 ;
height of ¢ 2.
Altitude 10,000’.
Type. Male. B.M. no. 6.7.1.35. Original number 252.
Collected 27th January, 1906, by Douglas Carruthers. One
specimen only. -
“ Caught in bog and rock region.”—D, C.
The interest of this animal lies in the immense extension
its discovery gives to the range of the genus Myosorex, which
(since the species without the extra tooth in the lower jaw
were separated as Sylvisorex) has been only known from
South Africa, the Zoutpansberg district of the Transvaal
being there the most northern recorded locality. That the
genus should turn up again at 10,000’ on Ruwenzori is a most
interesting fact.
The velvety mole-like fur of JL. blarina will, distinguish it
from all other forms except the decidedly larger M. Sclateri
talpinus of Zululand.
5. Sylvisorex lunaris, sp. n.
A large slaty-grey species, with a long slender muzzle.
Size much larger than in S. morto, about equal to middle-
140 Mr. O. Thomas on new
sized species of Crocidura. Fur rich and velvety; hairs of
back about 6 mm. in length. General colour dark slaty grey,
without variegation, but with a slight iridescence on the tips
of the hairs. Under surface little lighter, the tips of the hairs
pale brown. Upper surface of hands and feet brown, but
the flesh along their inner halves is paler than the outer ;
fore and hind claws about equal in size. Tail much shorter
than head and body, very finely haired, without longer
bristles ; brown above, rather paler below.
Skull markedly different from that of S. moro by its much
larger size, slender build, and long muzzle.
Teeth delicate. Unicuspids narrow, the anterior about
twice the area in cross-section of the other three, which are
subequal. Lower incisors uniform in thickness, not tapering,
their upper edges strongly serrated, with three well-marked
notches.
Dimensions of the type (measured in the flesh) :—
Head and body 86 mm.; tail 54; hind foot 14:5; ear 10.
Skull: condylo-basal length 22; basal length 19°8; ante-
rior breadth 6°4; greatest breadth across brain-case 10;
length of upper tooth-series 10.
Hab. Ruwenzori East, 12,500’. Other specimens from
altitudes of 7000' upwards.
Type. Male. B.M. no. 6. 7.1.38. Original number 643.
Collected 30th January, 1906, by R. B. Woosnam.
This distinct species may be readily distinguished from its
W.-African allies S. morio and S. Preussi by its larger size.
6. Funisciurus Carruthersi, sp. n.
A handsome yellowish-green species, with a bluish-grey
belly ; something like a gigantic #. poensis.
Size about as in /. pyrrhopus. Fur soft and rich; hairs
of back about 13-15 mm. in length. General colour above
bright yellowish olivaceous green, the hairs blackish with
rich yellow subterminal bands. Along the sides of the back
a suggestion of yellow lateral lines, in the position of those of
the pyrrhopus group, can be made out, but these are very
faint and scarcely to be distinguished from the yellow of the
flanks. Under surface and inner sides of limbs bluish grey,
the hairs dank slaty with whitish tips. Head like back ;
eyes rimmed above and below with dull whitish or orange-
whitish ; ears short, rounded, their inner surface greenish
yellow like the flanks, their outer surface and a small post-
auricular patch dull yellowish white. Upper surface of hands
and feet grizzled yellowish. ‘Tail coloured like the body, the
Mammals from Mount Ruwenzor?. 141
hairs black at base and on a broad subterminal ring, the
middle ring and the ends greenish yellow; a pencil of long
hairs at the tip of the tail wholly black.
Skull of about the size and general shape of that of
F. erythrogenys and other members of the pyrrhopus group.
Nasals square, parallel-sided. Postorbital processes further
forward on the skull than in erythrogenys. Teeth apparently
of the same general type as in F£. erythrogenys, but m’
considerably larger.
Dimensions of the type (measured in flesh) :—
Head and body 198 mm.; tail 192 ; hind foot 47:5 ; ear 20.
Skull: greatest length 49; basilar length 88; greatest
breadth 28; nasals 13x75; interorbital breadth 12:2;
palatilar length 20°2; length of upper tooth-series exclusive
of p® 8°8.
Another specimen (a male) has head and body 204 mm. ;
tail 205.
Hab. Ruwenzori East, 6500’.
Type. Female. B.M. no. 6. 7.1.53. Original number 262.
Collected 7th February, 1906, by Douglas Carruthers.
The affinities of this handsome and distinct species are by
no means clear. Its size and the indistinct lateral dorsal
lines suggest a relationship to the non-rufous members of the
pyrrhopus group, although it has not their characteristically
marked tail, and the bluish-grey belly is unlike anything
found among them.
7. Otomys Darimouthi, sp. n.
Lower incisors double-grooved. J/° with only six lamine.
Size rather larger than in O. Jacksont. Fur very fine,
long and woolly ; ordinary hairs of back about 17 mm. in
length. General colour above finely grizzled “ mummy-
brown,” not so coarsely marbled as in O. Jacksont. Under
surface drab-brown, the ends of the hairs pale clay-colour.
Head and ears of the prevailing body-colour. Upper
surface of hands and feet pale buffy. ‘ail black along its
upper surface, dull buffy on the sides and below.
Skull larger than in O. Jackson, its profile convex above
the orbits.
Upper incisors with a deep median and a fine internal
groove. Lower incisors with two well-marked subequal
grooves, as in O. Jacksont and typus. Laminar formula of
molars 5==—*,

Six specimens obtained.
This animal is related to the corresponding mountain-form
of Mt. Elgon, Otomys Jackson@, from 13,200’, but differs by
its larger size, more uniform coloration, and the possession of
only six lamine on the last upper molar.
I have had great pleasure in naming this distinet species
in honour of the Earl of Dartmouth, to whose generosity this
splendid exploration of Mount Ruwenzori is primarily due.
8. Otomys Denti, sp. n.
Incisive grooves as in OQ. irroratus, but m* with five laminze
only. Colour very dark.
Size rather smaller than in O. irroratus. Fur long and
fine ; ordinary hairs of back about 20 mm. in length. General
colour dark blackish brown (darker than “‘ bistre””) with a
coppery tinge, the rump almost black, the light rings on the
hairs dark tawny. Under surface and inner aspect of limbs
slaty black, a few only of the belly-hairs tipped with dull
buffy. Upper surface of hands and feet uniformly brownish
black. ‘Tail black throughout, above and below.
Skull smaller than that of O. 7zrroratus, more flattened
above, its profile not so convex above the orbits, the height
from tooth-row to supraorbital ridges markedly less.
Incisive grooves asin O.irroratus. Molar lamine
Dimensions of the type (measured in flesh) :—
Head and body 157 mm.; tail 89; hind foot 27; ear 21.
Skull: greatest length 36°6; basilar length 30°3; zygo-
matic breadth 18°63 nasals 14°7 x 6°8; interorbital breadth 4°5;
height from alveolus of m? to supraorbital ridge 10°8 ;_ palatilar

9, Dasymys montanus, sp. n.
A very long-haired species, with short tail.
Size medium. Fur very long and fine; the ordinary hairs
of the back about 15 mm. in length. General colour above
uniformly finely speckled mummy-brown, the light rings on
the hairs near clay-colour. A number of the longer hairs
with a greenish irilescence. Sides but little paler than back.
Under surface bluish grey, the slaty bases of the hairs little
hidden by the dull pale drab tips. Lars large, black, con-
trasting with the general brown colour. Upper surface of
hands and feet pale brown, the digits lighter. ‘Tail practically
naked, the scales quite unhidden, blackish throughout.
Skull shorter and broader and the zygomata more squarely
expanded anteriorly than in other species.

Type. Female. B.M.no.6.7.1.79. Original number 255.
Collected 30th January, 1906, by Douglas Carruthers.
I refer four specimens to this species, two of them of a
normal colour and two apparently melanoid, rather darker
than de Winton’s D. incomtus fuscus. Untortunately the
skulls of the normal-coloured specimens are much damaged,
but I do not think there is any reason to suppose the
blackish specimens are different from the brown ones.
D. montanus is readily distinguishable from all other
species by its long fur and short tail.
10. Dasymys medius, sp. n.
A grey species allied to D. Bentley.
Size medium, rather larger than in D. Bentleye. Fur
comparatively coarse and shaggy; hairs of back about 12-13 mm.
in length. General colour above greyish “ hair-brown,”
greyer on the head and fore-back, warmer and browner on
the rump; darkened throughout by the black ends to the
longer hairs. Sides greyer, passing gradually into the grey
of the under surface, where the tips of the hairs are dull
greyish white, their slaty bases showing through. Lars
well-haired, greyish brown, not markedly darker than the
general tone. Upper surface of hands and feet pale brown,

Tail rather long, thinly clothed with fine hairs, not hiding
the scales, brown above and below.
Skull larger than that of D. Bentleye and markedly
higher in the brain-case. Interorbital region parallel-sided,
evenly narrow throughout, not broadening posteriorly as in
D. Bentleye. Bulle decidedly larger than in that species.

No species of Dasymys have been hitherto described from
this part of Africa, the nearest being the Lower Congo
D. Bentleye, from which the present animal differs by the
characters above mentioned. From the D. montanus of the
higher altitudes of Ruwenzori it is, of course, at once distin-
guishable by its shorter coarser fur and much longer tail.
11. Mus Dennia, sp. n.
A small long-tailed species allied to Jf Allenit. Mammezx
2—2=8.
Size about as in M. Allent and M. carillus. Fur soft and
rather woolly; hairs of back about 9-10 mm. in length.
General colour not unlike that of JZ. carzllus, soft buffy fawn,
varying a good dealin the richness of the tone. Sides clearer
and more buffy. Under surface well defined whitish, sometimes
tinged with buffy. Head greyer than back ; lower part of sides
of muzzle white ; area round eyes black. Ears large, naked,
dark brown throughout. Upper surface of hands and feet
thinly haired, dull whitish. ‘Tail much longer than head and
body, fairly well haired terminally, greyish brown throughout.
Skull of the same delicate shape as in Af, Allen? and carillus,
and the zygomatic plate similarly little projected forward,
Supraorbital edges sharply square, but not beaded. Palatal
foramina much longer than in the two western species.
Dimensions of the type (measured in skin) :—
Head and body 96 mm. ; tail 154; hind foot 21; ear 21.
Skull: greatest length 27; basilar length 22:5; greatest
breadth 13°5; nasals 9°5; interorbital breadth 4:1; breadth
of brain-case 12°2; palatilar length 12; diastema 8; palatal
foramina 6°4 x 2°3; length of upper molar series 4.

This pretty mouse is no doubt allied to Mus Alleni, with
* which it shares the general proportions, shape of skull, and
number of mamme; but it differs by its softer, more buffy
fur and longer palatine foramina. In Aus carillus, otherwise
allied, there are only 1—2=6 mamme.
I have been in some doubt as to whether this or a larger
species obtained by the Ruwenzori Expedition should be
referred to de Winton’s M. Jacksoni, founded on a young
specimen from Entebbe, but the teeth of the type are more as
in the larger form, and there is a distinct, projection forward
of the zygomatic plate, practically absent in the present form.
A mouse from Mount Kenya, obtained by Prof. Mackinder
in 1899, and referred by me to J/. Jacksont, would also seem
to be assignable to Mus Dennice.
12. Mus univittatus lunaris, subsp. n.
General characters of the typical western J/. untvittatus,
but size smaller and colour more olivaceous, not turning
rufous on the rump, which is blackish olivaceous. Belly-
hairs greyish tipped with buffy ; a line down outer edge of
thighs also butty. Dorsal streak not sharply defined and
not extending on to neck and head. Upper surface of hands
blackish brown, of feet rufous brown. ‘L’ail practically naked,
black above, rather lighter below.
Skull similar to that of true wndvittatus, but smaller and
lighter throughout. Molars decidedly narrower.
Dimensions of the type (measured in flesh) :—
Head and body 108 mm.; tail 115; hind foot 25; ear 17.
Skull: greatest length 32; basilar length 24; greatest

with fine spines. General colour above dark coppery brown
(nearest to ‘ bistre”’), more blackish on the ramp; the light
rings on the hairs dark buffy. Under surface strongly con-
trasted rich buffy ochraceous, the hidden bases of the hairs
slaty grey. Head rather darker than back. Ears naked,
uniformly blackish. Outer side of limbs brown like sides,
inner sides buffy like belly ; upper surface of hands and feet
brown, with a tinge of buffy. ‘Tail finely scaled (20 rings to
the centimetre), practically naked, blackish throughout, or
rather lighter below proximally.
Skull stoutly built, with broad, squarely edged but not
ridged, interorbital region. Palatal foramina long, extending
nearly to the level of the middle of m'. First upper molar
with its anterior lobe less developed than in the smaller forms,
Dimensions of the type (measured in flesh) :—
Head and body 70 mm.; tail 68; hind foot 16; ear 13.

This species is related to Z. muscu/o¢des, Temm., but may
be readily recognized by its rich buffy under surface.
14. Lophuromys Woosnami, sp. n.
An olive-grey species with large ears and long tail.
Size about as in LZ. aquilus. Fur straight; hairs of back
about 10-11 mm. in length. General colour above between
“olive” and ‘bistre,’” without the warmer rufous tone
generally present in the East-African forms; the bases of
the hairs are, however, of a rufous-brown colour. Mixed
with the ordinary hairs of the back there are a variable
number of buffy-white hairs, which produce a_ speckling
somewhat similar to that of the grysbuck (Nototragus mela-
notis), but are almost absent in some specimens. Sides
rather paler than back. Colour of under surface not sharply
defined laterally, very variable, ranging from near wood-
brown to tawny clay-colour; the throat rather whiter. Head
like back ; area round eyes nearly black. Ears very large,
finely haired, black, with whitish edges. Upper surface of
hands and feet pale brownish white. ‘Tail long, slender,
almost naked, markedly less hairy than in the other species ;
blackish above, whitish flesh-colour below.
On a second Species of Mochocus. 147
Skull with a long slender muzzle; interorbital region
broad, edged with well-defined ridges, but without postorbital
projections; outer wall of anteorbital foramen reduced to a
narrow bar less than half the breadth of the corresponding
part in L. aguilus and flavopunctatus ; it is, however, simi-
larly narrow in the W.-African L. sikapust.
Incisors more as in Mus than in other Lophuromys, their
anterior surface not curved round in the way generally
characteristic of the present genus. Molars very broad, with
well-defined cusps; their pattern as usual.
Dimensions of the type (measured in flesh) :—
Head and body 118 mm.; tail 111; hind foot 22°5;
ear 23.
Skull: greatest length 30°5; basilar length 24; greatest
breadth 14°3; nasals 14.x3°2; imterorbital breadth 6°7 ;
diastema 8; palatilar length 12°4; palatine foramina 6°5;
length of upper molar series 4°8.
Alt. 6000’,
Type. Adult male. BM. no. 6. 7. 1. 170. Original
number 608. Collected 3lst December, 1905, by R. B.
Woosnam. Nine specimens.
This striking species is widely different from any of the
Central- and Kast-African forms of Lophuromys, and might
almost be considered generically distinct were it not that the
West-African L. stkapusi also possesses some of its characters.
Its large ears, long tail, and peculiar olive-coloured white-
speckled fur readily distinguish the species from all its allies,
and I have much pleasure in naming it after Mr. R. B.
Woosnam, to whose abilities so much of the success of the
Ruwenzori expedition is due.
XXI.—On a second Species of the Silurid Genus Mochocus.
By G. A. BouLencer, F.R.S.
WHEN dealing in these ‘ Annals,’ a few years ago *, with the
little-known genus Mochocus, Joannis (Rhinoglanis, Giinther),
I was acquainted with one species only, as I consider Rhino-
glanis typus, Gthr., from Gondokoro, and &. Vannutellid,
Vincig., from Lake Rudolf, as specifically identical with the
incorrectly described Mochocus niloticus of de Joannis, of
which I had then received a few specimens from Assuan,
where the fish bad been rediscovered by Mr. Loat. The

little fish has since been found by the same collector at various
localities on the Nile, between Beni Souef and Gondokoro,
and a second species has been discovered by him at Fashoda
and at Lake No, White Nile. For this new species I propose
the name of
Mochocus brevis.
Easily distinguished from the preceding by the shorter
caudal part of the body, the first dorsal fin being equally
distant from the end of the snout and from the root of the
caudal, or only a little nearer the former. Depth of body 34
to 4+ times in the total length, length of head 3 to 34 times.
Occiput and nuchal shield slightly tectiform, but without a
keel. Maxillary barbel reaching the extremity of the ventral
fin or a little beyond. First dorsal I 6, the spine without
any serration and always shorter than the head; second
dorsal 9-17; anal 9-10. Caudal peduncle only a little
longer than broad. Coloration as in JZ. niloticus, but
pectoral, ventral, and anal fins often with some brown spots.
Total length 31 mm.
Forty-two specimens from Fashoda and one from Lake No.
In MM. neloticus there is a series of three or four small bony
scutes, ankylosed to the interneural bones, on each side of
the base of the soft rays of the first dorsal fin; these little
scutes, which have hitherto been overlooked, are absent in
M. brevis.
XXII.—On a new Figmy Antelope obtained by Col. J. J.
Harrison in the Semliki Korest. By OLDFIELD THOMAS.
THE British Museum owes to Col. J. J. Harrison the skull
of a pigmy antelope from the Semliki Forest allied to the
Cameroon species described by de Winton as Neotragus
Batesi*, I have also had the opportunity of examining the
skin of the specimen, which is now in Co]. Harrison’s
collection.
Neotragus Batesi, as shown by de Winton, is in many
respects allied to both Neotragus and Nesotragus, and in the
light of the present examination of the new material, including
an additional example from the Cameroons, I am disposed to
consider it as representing a distinct genus, whose range

new Pigmy Antelope. 149
would be coextensive with the great Congo Torest. This
genus may be called
HYLARNUS*, gen. nov.
Intermediate between Neotragus and Nesotragus. Pre-
maxillo-maxillary vacuities present, as in the latter. Nasals
very broadly expanded posteriorly. Muzzle in front of orbit
comparatively short, the anterior wall of the orbit vertically
above p*, as in Neotragus, above m‘ or m? in Nesotragus.
Palation (back of bony palate) about level with the hinder
corner of m*, as in WVesotragus, opposite its front edge in
Neotragus.
Horns short, laid back nearly in the line of the frontal
profile, almost as in Weotragus ; stout, conical, smooth except
just at their base.
Type. Neotragus Batesi, de Wint.
The Eastern species obtained by Col. Harrison seems to be
specifically separable from 4H. Bates?, and I would propose
for it the name of
Hylarnus Harrisoni, sp. n.
External characters very much as in //, Bates, but the
colour-contrasts are more marked, the dark colours darker
and the light brighter.
General colour nearer to ‘‘ cinnamon” of Ridgway, that of
Batesi approaching “ russet”’; central dorsal area darkened
by the black tips to the hairs. Jorehead and crown dark
brown, a fine lightish line over each eye. Hairs of outer
surface of ears black, of inner white. Chin and interramia
nearly pure white. ‘Throat-band brownish cinnamon. Belly
sharply defined white. Front of limbs dark brown, inter-
rupted over the metapodials and basal phalanges by an ill-
detined elongated whitish patch, which is succeeded again by
brown on the penultimate phalanges. Tail imperfect in the
type, its basal portion coloured like the body.
Skull with the nasals even broader posteriorly than in
H, Batesi, running out on each side to a well-marked angle.
Premaxillo-maxillary vacuity larger in the single specimen.
Horns longer and set at a slightly greater angle upwards.
Dimensions of the typical skull :—
Greatest length 110 mm.; basal length 96°5; greatest
breadth 52; muzzle to orbit 51; nasals 87 x 23; breadth of
brain-case 36 ; muzzle to front of p? 36; palate length 66;
length of upper tooth-series 32.

19/3/02 ; 10 fath.
The females and young males (which differ from the
females only by the absence of the incubatory lamellz)
cannot be distinguished from 8. Saundersi, Stebbing, with
which this species may be identical *. ‘lhe two large males
mentioned above, however, show such a marked difference in
the great development of the meral joints of the last three
pairs of pereeopods, that at first sight I took them for a
distinct species. As, however, they were associated with the
smaller form, with which they agree in the rest of their
structure, I have no doubt that they are only full-grown
males. It may be remembered that in the adult male of our
own Orchestia littorea (Mont.) we have asimilar enlargement
of the meral joint in the last pair of perseopods.
XXIV.—Description of a new Cyprinodont Fish of the Genus
Jenynsia from Argentina. By C. Tare Regan, B.A.
Jenynsia maculata.
Depth of body 3} to 4 in the length, length of head 32
to 4. -Snout as long as or shorter than eye, the diameter of
which is 3} to 4 in the length of head, interorbital width 2
to 21. Body regularly and completely scaled; 28 to 30
scales in a longitudinal series. Dorsal 8-9; origin equi-
distant from extremity of operculum and base of caudal or
from eye and end of caudal. Anal 8-9, opposite to the
dorsal ( ¢ ) or a little in advance of it (¢). Caudal rounded
or subtruncate. Pectoral about 3? the length of head;
ventrals extending to the vent. Sides with 3 or 4 irregular
series of more or Jess oblong blackish spots.
Several examples, measuring up to 73 mm. in total length,
from Cachi, Salta, Argentina, at an elevation of 2500 metres,
collected by Herr J. Steinbach.
This species is very close to Jenynsia lineata, Jenyns,
which has the dorsal fin a little more advanced and has the
spots on the sides smaller and more numerous, forming
regular longitudinal lines along the series of scales.

The Fauna of British India, including Ceylon and Burma. Pub-
lished under the authority of the Secretary of State for India in
Council. Edited by Lt.-Col. C. T. Bryenam. — Rhynchota.
Vol. ILL. (Heteroptera — Homoptera). By W. L. Disranr.
London; Taylor & Francis. Pp. xiv, 503; text-figs. 266.
Cot. Bryenam has prefixed a preface to this volume (the first
published under his editorship) expressing the general regret felt
at the death of Dr. Blanford, the originator of the series of works
on the Fauna of British India, and noticing the arrangements made
for future volumes, comprising works on Coleoptera, Lepidoptera,
and Mollusca.
The present volume contains the conclusion (families 17 to 24) of
the Heteroptera, chiefly including the not very extensive but ex-
tremely interesting Water-Bugs, and the first two families of
Homoptera—the Cicadidee (three subfamilies) and Fulgoride (twelve
subfamilies), It will thus be seen that the largest, and in the case
of the Homoptera the handsomest and most conspicuous, species fall
into the present volume. ‘These sections are, however, very poorly
represented in Britain. Of the great and vociferous family Cicadidie
we have only a single rare and local representative, and even this one
of the smaller species, measuring under 2 inches in expanse, though
from 5 to 6 or even 7 inches is no uncommon size in India and other
warm countries. Even so, however, our own species is the largest
British species of its order, except the curious aquatic Ranatra
belonging to the Heteroptera. The Water-Bugs and Fulgoride are
somewhat better represented in Britain, but the latter only by
comparatively small and insignificant species, whereas the Indian
Fulgoride are as large and brightly coloured as butterflies and
tiger-moths, which, indeed, some of the species resemble, while
others are remarkable for the large and often curiously shaped
protuberance on the head, which, however, finds its greatest deve-
lopment not in an Indian species, but in the large South-American
lantern-fly, which sometimes measures nearly 6 inches across the
wings. It is curious that both the South-American lantern-flies
and the East-Indian candle-flies should be reputed luminous, and
yet that modern entomologists should not have been able to confirm
the statement in either one case or the other.
We hope that the high standard of excellence which the ‘ Fauna
of British India’ has exhibited since its commencement will be
maintained permanently by the combined efforts of editors, authors,
and artists.
A Synonymic Catalogue of Homoptera—Part I. Cicadide. By
W. L. Distant. London: Printed by Order of the Trustees of
the British Musenm, 1906. 8yo. Pp. 207.

so useful to entomologists since the Trustees of the British Museum
decided to adopt that form, instead of the long series of publications
156 Miscellaneous.
in a smaller size with blue paper covers which preceded them.
The present Catalogue is devoted to the very interesting family of
the Cicadide, which includes the largest species of the suborder
Homoptera, but which is entirely unrepresented in the British
Islands, except by a single rare and local species, found chiefly in
the New Forest. -
The loud stridulation of many of the foreign species is a great
feature of forest life abroad; and even in Greece the Cicada’s
“song” has been famous from classical times onwards.
Mr. Distant has long been one of the leading authorities on this
family, having published a ‘ Monograph of Oriental Cicadide’ as
long ago as 1889, and having also included it in the third volume on
Rhynchota in the ‘ Fauna of British India,’ published during the
present year.
The Catalogue before us extends to 188 pages, exclusive of Index,
which fills 19 pages in triple columns. The number of genera
admitted is 179, and, besides the full synonymy, useful tables are
given of the genera in each division.
The enormous increase in entomological literature renders the
frequent publication of monographs and catalogues (which are as
grammars and dictionaries) indispensable to working entomologists ;
and we cannot have too many of them, provided they are written by
men-well up in their subject and are fairly complete and up to date.
Opinions on details differ; but there are three particulars in
which we think Mr. Distant’s book might have been improved.
First, we think that the species under each genus should have been
numbered as well as the genera. Secondly, the species contained in
the Natural History Museum should have been marked, and all
names the types of which are included in the series should have
been specially indicated. Thirdly, we find a list of undetermined
species at the end of the book; but we should have preferred to see
all these, except those absolutely unrecognizably described without
figures, assigned to their probable places, if necessary with a query.
In the case of Walker’s species not in the Museum, the types
perhaps still exist in other British collections.
We do not make these remarks as criticisms, but as suggestions,
and have no hesitation in recommending Mr. Distant’s work as
absolutely indispensable to all students of the Cicadide.

Locusts in Hungary.
Ir is stated in a morning paper to-day that locusts are committing
ravages in some parts of Hungary. I should be much obliged to
some Hungarian entomologist if he would kindly send me specimens
for identification. W. F. Korsy.

XXV.— Natural History Notes from RI.M.S. ‘Investigator?
—Series III., No.10. On Mollusca from the Bay of Bengal
and the Arabian Sea. By Ensar A. Suira, I.S.0.
Ten communications to these ‘ Annals’? upon the Mollusca
obtained by the ‘Investigator’ have already appeared—two
by the late Professor Wood-Mason and Professor Alcock
(1891, vol. vu. pp. 15-19, and vol. vill. pp. 443-448), and
eight by the present writer (1894, vol. xiv. pp. 157-174;
l. c. pp. 366-368 ; 1895, vol. xvi. pp. 1-19; /. c. pp. 262-265 ;
1896, vol. xviii. pp. 367-375 ; 1899, vol. iv. pp. 237-251;
1904, vol. xiii. pp. 453-473 ; vol. xiv. pp. 1-14). The new
and more interesting species have been figured in the above
papers or in the “ Illustrations of the Zoology of the Investi-
gator,’”’ edited by Prof. Alcock. The species still unfigured
and those described in the following pages will eventually be
illustrated in the latter work.
Of the numerous species now described the most inter-
esting, perhaps, is the Morio Alcocki, which may be regarded
as an Indian-Ocean representative of the Mediterranean and
North-Atlantic M. rugosa. The occurrence of Oocorys
sulcata, another Atlantic form, off Ceylon, is also extremely
interesting. Other fine shells are Bathybembix Nevilli, Gaza
Frederici, ”Dentalium cor nu-bovis, and Nucula (Acila) granu-
lata. What is especially noticeable in all these collections
is the absence of many new generic types—indeed, up to the
Ann. & Mag. N. Hist. Ser. 7. Vol. xviii. 12
158
present only two have been discovered,
Mr. E. A. Smith on Mollusca from the
namely, Pontio-
thauma*, described in 1895, and Manaria, in the present
paper.

The specimens from Station 260 are much ‘larger than any
examples which I have seen from Japan, the original locality
of this species. The largest is 80 mm. long and 37 broad.
Like the specimens mentioned at the above reference all
those in the present series have the top of the spire eroded.
The operculum is narrow, 17 mm. in length, and has the
right margin serrated.

According to Mr. Pace this species should be removed
from Pontiothauma, although in many respects it closely
agrees with that genus.

Another specimen, in worn condition, is rather larger than
the type, being 39 mm. in length. The cost in this species
are about eighteen in number, somewhat acute, and do not
reach to the suture above, but terminate at the depression at
the upper part of the whorls. The transverse lire are fine,
contiguous, and continuous over and between the costz.
Animal without eyes or operculum, and the foot is much
flattened behind.

Ceylon, 1085 fath.
This species differs from P. mirabile, Smith, in having the
whorls angulated in the middle, in the finer spiral lire, more
slender coste, &c. The ribs are nineteen in number upon
the body-whor] and only slightly developed in the concavity
or upper part of the whorls.
A specimen from Station 318 has only sixteen coste and
the aperture is white within.
Animal apparently without eyes or operculum.
Named after Mr. 8. Pace, who kindly reported upon the
soft parts of the genus Pontiothauma (Journ. Linn. Soc.,

Several specimens rather smaller than the type, now in
the British Museum, but otherwise the same. The operculum
is rather thick, semioval, having one side straight and the
outer margin curved. ‘The nucleus is at the middle of the
straight edge, the outer surface being finely concentrically
striated and the underside with a raised edge, with some
concentric wrinkles in the middle. In general form the
shell bears a resemblance to C. bimarginata, Lamarck, and
C. diadema, Kiener.

Hab. Station 283, off E. of Ceylon, 1086 fath.
The chief characteristics of this species, represented by a
unique specimen, are the smooth concavity at the upper part
of the whorls, exhibiting only very delicate lines of growth
and faint traces of spiral striz, the numerous slender oblique
coste upon the lower two thirds of each whorl, and the
distinct close wavy striz on and between the mbs. These
are nineteen in number upon the penultimate volution,
thickest at their upper ends, obliquely curved, attenuated
below, and only just reach to the suture. The body-whorl,
excepting in the concayity above, is delicately wavy striated
throughout.

Only a single example obtained. ‘The lines of growth are
rather strong and very flexuous, and on passing the delicate
spiral lire, except in the concavity above the angle of the
whorls and at the base of the body-whorl, are delicately
nodulous. The last volution below the nodose periphery has
about fifteen liree, of which about six of the upper ones are
nodulous, the rest, around the anterior contracted portion,
being simple and thread-like. The tubercles on the angle
are about eighteen in number, and the lire above it three or
four.

pl. xi. fig. 11), but with a longer spire, shorter body-whorl,
with the granules closer and squarer, and the margin of the
labrum more denticulate. N. ravida, A. Adams, is another
allied form, but much more globose. As in many other
species of Nassa, the upper row of nodules below the suture
are slightly larger than the rest.

A single specimen in dead condition. It somewhat recalls
the British Tritonofusus (Siphonorbis) fusiformis (Broderip),
except that the body-whorl is produced into a longer rostrum
anteriorly.
The spiral thread-like lines are very fine and close-set, and
occasionally two or three form slightly raised ridges. Three
or four such ridges are noticeable on the upper whorls and
almost form nodules upon the coste.. The lines of growth
are close together, and on crossing the transverse lire give
them a minutely crispate appearance.
ManaRIa, gen. nov.
Testa fusiformis, longitudinaliter costata, periostraco induta ; colu-
mella in medio plica unica intrante instructa; Jabrum ad marginem

This genus has the general aspect of a costate Tritonofusus,
but is distinguished by the fold on the columella and the
hrate aperture.

The longitudinal cost are not very thick and do not vary
much in stoutness, and they are crossed by the spiral sulci
or striz, which are about eight i in number on the penultimate
whorl. The periostracum is rather thick and longitudinally
striated with the lines of growth. The denticles within the
labrum are six or seven in number, and from them faint
lire run inwards. The fold on the columella is peculiar and
forms a prominence at the middle. It is somewhat oblique,
but how far it is continued up the columella I cannot say, as
only a single specimen is at hand, and that is too precious to
break up. Named in honour of Mr. Edgar Thurston, of the
Madras Museum.

Very like 7. car -duelis, Wateone pe off Sydney in

spines at the angle of the whorls. The lamelle which form
the spines are quite closely appressed to the shell, whereas
in carduelis they stand away quite free from the general
surface of the whorls. A very similar form, 7. actinophorus,
Dall, occurs in the West Indies in 140-248 fath.

A single specimen, length 42°5 mm., diam. 28, differs
from the ‘ Challenger’ Atlantic form in size and in possessing
an unclosed umbilical opening. The latter, however, might
possibly be concealed if the columellar callus were not
broken at that part or had the specimen lived a little longer
and so completed the reflection of the callosity. The spiral
liree appear to be rather more remote from one another, but
this results from the larger size of the specimen. The
remarkable lines of growth, causing the lire to be crenulated,
are of the same character in both specimens, and the oper-
culum is horny and spiral, as described and figured by
Verrill * of his genus Benthodolium; which is_ evidently

synonymous with Oocorys ; indeed, it seems almost certain
that O.sulcata, Fischer, O. Fischeri, Locard, and B. ahbys-
sorum, Verrill, are varieties of one and the same species.
The last-named species is described both by Dall and Verrill
as having an umbilical chink, a feature present in the Indian
Ocean shell. It is essentially a deep-water genus, having
been recorded by Verrill from 2221 fath., by Fischer from
1980 fath., by Watson from 1850 fath., by Dall from
955 fath., and the present specimen is from 1912 fath.
Dall, however, has mentioned the occurrence of O. abys-
sorum in 169 fath. in the northern part of the Gulf of
Mexico,
In connexion with similar forms in the Indian Ocean and
the Atlantic, I might recall the fact of the occurrence of
Lucina spinifera (Montagu) * and Poromya tornata (Jeffreys)
in both oceans, and that Turbo indicus, Smith, from off
Ceylon in 597 fath., is scarcely separable from T. peloritanus,

XXVI.— Notes on the Genus Tamarrha, Wkr. [Lee.—
Trnerna]. By the Rt. Hon. Lorn Watsinenam, M.A.,
LL.D., F.R.S.
Mr. Buscx (Pr. U.S. Nat. Mus. xxx. 728-30) discusses
the genus Tamarrha, Wkr., and quotes a paragraph for
which I am responsible (Proc. Zool. Soc Lond. 1897, p. 114).
13*
176 Lord Walsingham—WNotes on
I wrote of T. nivosella, Wkr. :—‘‘ At the time [when I had
wrongly sunk Tamarrha as a synonym of Psecadia] I had
seen only the type of Walker’s other species nivosella, which
isa 9.”? Had I used the word ‘ examined” for “ seen’
the meauing of the paragraph would have been more
apparent.
Mr. Busck is now able to say that T. gelidella, Wkr., is
not a Psecadia (as I had supposed), but is congeneric with -
the type of Tamarrha, a conclusion which he founds on his
study of West-Indian specimens ; and, after admitting the
synonymy of his own genus Babaiara, which consequently
sinks, he writes it ‘ is evidently the species which Zeller sub-
sequently described as Psecadia exornatella.”
Zeller described (Hor. Soe. Ent. Ross. xii. pp. 238-40)
Psecadia exornata (uot exornatel/a) from two males taken at
Chanchamayo, Peru, with which he associated under a separate
description two smaller males from Cuba, all in Museum
Staudinger. I have a single male from the same Peruvian
collection, purchased from Staudinger in 1891, which agrees
absolutely with Zeller’s figure and with his first description,
and has a smooth head. It seems more than probable that
the Cuban specimens are not identical with those from Peru.
I have also a female from Jamaica in which the costal shade
reaches the base instead of being broken up into spots ; the
central band is distinctly continuous with the costal shade,
not separated from it, the white patches much more clearly
defined and separated from each other; this specimen agrees
absolutely with the type of 7. gelidella, Wkr., and is certainly
not the Peruvian exornata, Zell. It may be interesting to
observe that the locality “ Chanchamayo” is not to be found
in maps; the collector Than.m is known to have referred to
a valley on the eastern slopes of the Andes; ‘ Dr. Staudinger
schreibt mir dariiber: Thamm sammelte in den Cordilleren
in einer Hoéhe von 2000-8000’, selten noch héher, am
Chanchamayo, einem Nebentluss des sich in den Amazonen-
strom ergiessenden Ucayale, unter dem 12 Grad siidlicher
Breite” [Z., Hor Soc. Ent. Ross. xiii. 4 (1877)]. “ Chancha-
mayo” is said tomean “ Humming- bird? in the local language.
Such confusion is not unfrequent among travellers, as when
Captain Cook tried to ascertain the native name for a
well-known animal and received the answer “* Kangaroo,”
signifying “I don’t know what you mean.’
“We now come to Tamarrha niv osella, Wkr., the type of
the genus, or, rather, the selected exponent when Tamarrha
was revived. paie in describing his Psecadia adustelia,
which I have identified as a synonym of nivosella, Wkr.,
the Genus Tamarrha, Wr. a
regarded his species as sexually dimorphic, and pointed out
the differences between the ¢ and the ?, especially the
greater extent of the grey colouring in the g, which in the
? was cut off by the white costal area above the dorsal
patch. Ihave both these from Jamaica, with both sexes of
each, and they are distinct species. ‘The less clouded form,
of which Zeller had only the ?, is not the same as the ?
deseribed by Walker, aud seems nniformly smaller and paler
than the other; but there is one point which now enables
me to identify without doubt Zellers ¢ adusitella—he
specially mentions “ Fiihler beim ¢ mit auffallend verlang-
erten.... Wurzelgliede.” This applies to the darker form
only, precisely as seen by Zeller, and is most remarkable.
Walker’s two 2 9 are undoubtedly this species, of which I
have now a @ with the long basal joint, but his ¢ differs in
the short basal joint of the antennze as well as in the details
of the markings.
There are at least three other species, differing very slightly,
from Cuba, Jamaica, and Domingo. Zeller’s Portorico
females may probably come to be identified with one of these
aud possibly with the genus Hwarne, Mschl.+ Saalm.
I send these notes at once, since | have no leisure at present
to study in further detail the interesting papers on Micro-
lepidoptera lately published and kindly sent by Mr. Busck.
No one can more highly appreciate the excellent work he is
doing ; but it seems a pity that facilities are not afforded to
authors of scientific papers published by the American
Government for correcting proofs. Had the proofs passed
through the author’s hands, such errors as “ Zellar” for
“ Zeiler,” “Flore” for ‘ Hore,” ‘‘nievosella” for “ nivo-
sella,” “ Hyponementide ” for ‘‘ Hyponomeutide,” &c., &c.,
would certainly have been avoided: all these and ‘ Ypono-
meutide,” to which Z am said to have referred Tamarrha,
are on p. 729.
If I were wrong in placing the genus Tamarrha in the
Hyponomeutidee, additional matenal obliges me to take
exception also to associating it with the Gicophoride. Does
Mr, Busck know the African genus Gymnogramma aud others
with veins 7+8 of the fore wings stalked, or Trichostibas,
Zeller, (=§ Penthetria, H. Edw.) ? and would these affect his
opinion as to the extent of the Hyponomeutide? I would
now rather incline to placing Tamarrha with the Azinide,
founded on an Asiatic genus and characterized by the con-
tinuation of the discoidal vein direct to vein 8.
I cannot conclude without drawing attention to a quotation
on p. 733, where the author cites Dr. Dietz’s reference to
178 Lord Walsingham on a new Tineid Moth.
“the apparently heretofore overlooked” character, the more
or less furcation of “vein 1 6 in the hind wings,” which he
finds in several genera of the Tineine. In Tr. Ent. Soc.
Lond. 1891, 102, when criticising de Peyerimhofi’s reliance
on this character as distinguishing the Tortricide from the
Tineide, I remarked that the furcation of vein 16 occurred
in a number of Tineid genera, and even in “ Tinea tapetzella,
L., itself.”
May I suggest that the application of the word “‘ overlooked”
is capable of extension, but not in the direction indicated
(vide l. c. pl. vii.) ?

When the forewings are denuded transverse striz are
observable, between the veins, giving a reticulated appearance.
These are due to lines of thickening from which the majority
of the highly-developed scales arise; they are almost per-
pendicular and extend from costatodorsum. ‘This structure
oceurs also in Opogona aurisquamosa, Btl., and in Stagmato-
phora (Pyroderces) argyrogrammos, Z.; if not overlooked it
is apparently unrecorded.
The specimens are broken and in poor condition. The
habits of the species are particularly interesting, as being
apparently similar to those of Batrachedra Rileyi, Wlsm.,
discovered in Georgia among rotten cotton-bolls. The
similarity in colour and markings between the two insects
is so close as to suggest the idea of mimicry (which, in
this case, can of course be only synchromatism) ; but the
form of the palpi and the breadth of the hind wings, apart
from the question of neuration, are at once sufficient to
distinguish them and to place them in different genera,
Note.——In February last Mr. Walter Draper, of the
Government Gardens, Delta Barrage, Egypt, sent to the
British Museum some cotton-pods infested with a Hemipterous
insect (Oxycarenus hyalinipennis, Costa) and numerous
small caterpillars. Lately on looking at the bottle I found
a number of small moths, all dead, and mostly with all
their scales rubbed off. As Mr. Draper, who discovered this
new pest in the cotton, wished to have its name, I sent
specimens to Lord Walsingham for determination, and these
are the subjects of the foregoing description.—Cuas. O.

XXVIII.—On new Species of Histeridee and Notices of others.
By G. Lewis, F.L.S.
TuHIs paper, the twenty-eighth, follows one published last
April, and the series as a whole will in a measure serve as a
supplement to Marseul’s Monograph of 1853-1864. Marseul
established very few genera, less than forty in all, and appa-
rently he was reluctant to increase their number, although,
had he had more material at his hand, there is little doubt
he would have founded others. He would not, for instance,
lave associated Phylloma bahiense and corticale, F., or
Sternaulua zlindica and Edwardst, Mars., in the same
genera if he had known more than a single species of each
kind. ‘To-day our knowledge of the family is but a little
more advanced, as the Histeridz belong to a class of insects
which, being small and of secretive habits, do not come
within the observation of general collectors, and they also
require special methods of search, as some attach themselves
to other insects, such as ants, termites, wood-boring Coleo-
ptera, &c. It is a matter for regret that collectors, while over-
looking the Histeridze, miss many curious species of Colydiidze
and others which are commensal with them; this applies
especially to collections made in the tropics.
One of the most curious discoveries of recent years is the
finding of one of the Saprinini, Chelyoxenus xerobatis, Hubb.,
which has asymmetrical claws, in the galleries made by a
tortoise, Gopherus polyphemus, in Florida, and another of
nine or ten species of MJonoplius in the tenements raised by
the termite Hodotermes Havilandi, Sh., in 8. Africa.
In my recent Catalogue varietal names (Ann. & Mag. Nat.
Hist. vol. xvi. p. 340, 1905) appear as part of the synonymy,
and I observe with satistaction that the Recorder of the
‘Zoological Record,’ 1904, remarks that “the naming of
varieties is at present carried to a great extent, and we have
not space to record them all, but we endeavour to point out
all that appear to be of real importance.’ Any name
reasonably and purposely omitted in the annual register of
the ‘ Record’ is practically deleted, and a recognized method
of deletion of superfluous names is annually becoming more
and more desirable. The Recorder also says: “ It may not be
superfluous to add that the study of variation is by no means
dependent for advancement on the naming of varieties.”

L. 9 mill. (absque mandibulis).
This species is very similar to LZ. latum, Mars., but it
differs by being more oval, by the canaliculation of the
mentum, on the anterior edge of which are two small tubercles,
by the shorter mandibles, by the thoracic stria being short-
ened behind the middle (not at the base only), and by the
stria terminating at the anterior angle, not close to the eyes,
where it widens out into a small and shallow fovea. ‘The
punctuation of the propygidium is also finer. L. patulum
particularly agrees with P. datum in the second dorsal stria
being markedly incurved at the base, by the prosternum being
broad, and in having the mentum of an exceptional structure.
As regards the width of the prosternum, both species agree
with those of //olo/epta, but Marseul placed datum in Lioderma,
and it is known that these genera are not at present well
defined. ‘The pygidium of L. datum is finely punctulate, not
smooth, as stated by Marseul in his Monograph, p. 215.

the thorax, marginal stria widely interrupted behind the
head, the lateral stria is not deeply impressed (like those of
the other species of the genus) and it is broken near the base ;

is 1mpunctate, with the marginal stria widely interrupted in
front; the anterior femora are smooth.
In its general outline this species resembles P. javanus,
Er., except that it is rather more parallel laterally ; it is
remarkable for its simple mandibles and interrupted lateral
thoracic stria. The anterior femora of javanus are trans-
versely rugose and the anterior prosternal lobe is punctured
and the marginal stria complete.

‘This species is larger than A. tacdturnus, Mars., and it has
three inner apical dorsal strie, which are wanting in Marseul’s

A. taciturnus, Mars., and A. latiusculus, Sch., although
Marseul says s (Mon. p- 244) that the mesosternum of taciturnus
is without a marginal stria, meaning that the stria along the
border is incomplete.

Some confusion appertaining to these genera, as Stal had
not given the type of his genus Pecilostola, I sought the
assistance of Dr, Aurivillius, who kindly examined the
specimens in the Stockholm Museum, and informed me :—
“The genus Pecilostola, Stal, is not in onr collection. Under
the heading of Hypepa there are, however, three species—
costata, Fabr., semivitrea, Stal*, and venosa, Germ. Only
the first two of these species agrees with Stal’s description of
Hypepa; the third, venosa, agrees, as it seems to me, well
with the description of L@cilostola, and was probably the
species on which Stal founded that genus.” ‘There seems
scarcely a doubt that Dr. Aurivillius has solved the problem,

Cercocebus Hamlyni, sp. n. (PI. VIL.)
Face pale flesh-coloured, with darker and lighter, larger
and smaller spots of brown pigment, most plentiful round
and below the eyes and on the bare part of the cheek, but
absent on the upper and lower lips and on the nose. Upper
lids whiter than surrounding skin, with white eyelashes.
Iris of eyes olive-brown ; ball of the eye, where visible, white,
with brown pigment-spots. Brow-ridge white, with a few
pigment-spots. ars flesh-coloured, with a few pigment-
spots. Summit of head thickly hairy, the hairs longest along
the middle and forming posteriorly a parieto-occipital crest,
for the most part blackish to the roots, with greyish tips. In
front and at the sides this black crown is sharply detined by
the greyish-white hair forming a narrow brow-band and by
the hair of the same colour clothing the cheeks and the area
behind the ear. The hairs on the cheek forming a long
backwardly directed tuft concealing and projecting beyond
the lower half of the ear. make it
look more like a mole than a shrew. ‘The comparatively
normal position of the extra lower unicuspid shows an even
more primitive condition than in Myosorex, which is the only
other genus of Soricide that has retained this tooth.
Surdisorex Nore, sp. 0.
Size rather larger than in any known species of Myosorex.
Fur close and mole-like, rather coarser than in average
Myosorex; hairs of back about 6 mm. in length. General
colour above dark bistre with a greenish iridescence ; indi-
vidual hairs slaty grey for five-sixths their length, their ends
pale brown with darker tips. Under surface similar but
rather paler, without line of demarcation. Har-conches
absent. Upper sides of hands and feet dark brown ; fore claws
very long and powerful, those of the second, third, and fourth
digits subequal, about 5°5 mm. in length (measured from the
base above) ; pollex with a pointed claw over 2 mm. long ;
median hind claws about 2°5-2°8 mm. in length. Tail very
short, not twice the length of the hind foot, closely hairy,
without longer bristles, dark brown above and below,
Skull longer than in any known species of Myosorez, but
more slender, the palatal area actually narrower than in the
smaller M. Sclater? ta/pinus, though decidedly longer. ‘Teeth
much as in Myosorea, but the second upper unicuspid is pro-
portionally larger, about one third the size of the first in cross
section, and the third is more elongated and nearly touches the
large pm*, leaving no space for a fourth unicuspid. Below

there is a marked difference in the shape and position of the
minute extra tooth characteristic of Myosorex. In the latter
it is nearly in the centre line of the tooth-row, jammed closely
between the two usual unicuspid teeth, its transverse several
times greater than its longitudinal diameter, and looking more
like a piece of the cingulum of the first unicuspid than a
separate tooth. Onthe other hand in Surdisorex the tooth is
nearly circular in section, and is placed in a more normal
position in the inner angle between the two larger teetl—in
fact, almost exactly as in the bat 7rachops.

Upper incisors each with a single clearly defined groove ;
the grooves more external than in Pelomys, the outer portion
of the tooth only about one half the breadth of the inner.

type Mylomys Cuninghamet.
The highly modified teeth of this rat compel me to dis-
tinguish it from Pelomys, which it resembles in its general
appearance and in the grooving of its upper incisors. The
molars of Pelomys are much more rounded in all respects, with
low central cusps and without angular projections connecting
the lamine. In some respects the molars of the Abyssinian
rats which in 1902 * I assigned with doubt to Pe/omys—
“ P.” dembeensis and Llarringtoni—are intermediate between
those of Mylomys and Pelomys; but I am now convinced
that these animals should not be included in Pelomys, and
think they may be provisionally looked upon as aberrant
members of Gnomys, the so-called grooving of their upper
incisors being hardly worthy of the name, and their molars
being very similarly formed to those of that group.
In any case the striking rat discovered by Mrs. Holms-
Tarn cannot be assigned to any known genus, and needs a
special one to be formed for its reception.

XXXIV.—The Morphology of the Madreporaria.—VIIL.
The Primary Septa of the Rugosa*, By J. E. DUERDEN,
Ph.D., A.R.C.S8.(Lond.), Professor of Zoology, Rhodes
University College, Grahamstown, Cape Colony.
In the first paper of this series, published in 1902, entitled
“The Relationships of the Rugosa (Tetracoralla) to the Living
Zoanthex,”’ I confirmed Count de Pourtalés’s observation that
the rugose coral Lophophyllum proliferum, E. & H., has six
primary septa (protosepta), all equal in size and situated at
* The first two parts of this series of papers appeared in the ‘ Johns
Hopkins University Circulars,’ vol. xxi. nos. 155 & 157, and were re-
printed in the Ann. & Mag. Nat. Hist. ser. 7, vols. ix. & x., May and
August 1902; the third and fourth parts appeared in the Ann. & Mag.
Nat. Hist. vol. x., November 1902, and vol. x1., February 1903; the fifth
and sixth parts in the ‘Biological Bulletin,’ vol. vii., July 1904, and

of an appropriation from the Carnegie Institution, Washington. I am
under great obligations to Prof. Sydney J. Hickson, F.R.S., for seeing the
paper through the press in England.

equal distances apart. Also, by means of a series of micro-
scopic sections, I established that the subsequent principal
septa (metasepta) are added ina bilateral manner within four
of the six primary interseptal chambers, the two middle and
the two ventro-lateral chambers ; further, that the additions
are made at only one region within each chamber, immediately
dorsal to the alar or ventro-lateral septum in the case of the
middle chambers, and immediately next to the cardinal or
ventral directive septum in the ventro-lateral chambers. I
then proceeded to show that of all modern Anthozoa the
Rugosa find their nearest representatives in the zoanthid
actinians. In the Zoanthee the secondary mesenteries
(metacnemes) are added bilaterally at one region within each
of the primary ventro-lateral intermesenterial chambers or
exoceeles, exactly as are the septa in the Rugosa, but no
mesenteries are added within the primary middle and dorso-
lateral exoceeles. From our knowledge of the relationship of
the septa and mesenteries in modern corals, it was assumed
that the two cycles of septa of the rugose corals were formed
within mesenterial chambers similar to those characteristic
of the zoanthids, the principal or larger septa within entocceles
and the secondary or smaller septa within exocceles ; hence
the former are termed entosepta and the latter exosepta.
In the sixth paper of this series, published in 1905, with
the subtitle ‘The Fossula in Rugose Corals,” I endeavoured
to show, from a series of developmental stages in Streptelasma
rectum, Hall, the true nature of the alar fossule, and also
that of the eardinal or ventral directive fossula. I demon-
strated that the latter fossula is composite in character, at
any rate during the early stages; that it is made up of a
series of incomplete septa on each side of the ventral directive
septum, while the ventral directive septum is itself smaller
than the other principal septa. It was suggested that the
small ventral directive septum is to be correlated with the
presence in the rugose polyp of a ventral siphonoglyph or
gonidial groove, similar to that characteristic of modern
zoanthid polyps. This interpretation I considered as greatly
strengthening the earlier suggestion that the Rugosa are
nearly related to the Zoanthee, and expressed it in the
following terms (p. 40) : ‘‘ In the absence of the rugose polyp
itself, no surer proof of the relationship of the group to the
zoanthids could, to my mind, by adduced than that which
admits of the correlation of the simple cardinal fossula with
a ventral stomodeal groove.” Figures were given (l. ¢.
fies. 2-11) showing that in Streptelasma rectum, as in Lopho-
phyllum, there are six primary septa, and that the subsequent
228 Prof. J. E. Duerden on the
septa are added in the same bilateral manner at four distinct
regions,
Within the present year, Mr. C. E. Gordon, working in
the Paleontological Laboratory of Columbia University, New
York, has published a paper, “‘ Studies on Early Stages in
Paleozoic Corals” (Amer. Journ. Science, vol. xxi. Feb. 1906),
devoted almost exclusively to a discussion of my first
contribution. By inverting my figures Gordon shows that
the sections of Lophophyllum can be brought into harmony
with Kunth’s oft-repeated figure representing the schematic
septal plan of a zaphrentoid coral, a fact of which there
could be no possibility of dispute. Further, while admitting
the hexameral nature of Lophophyllum, he attempts to show
that it docs not represent the true primary character of the
Rugosa, but is to be explained as a departure from a primary
tetramerism, due to acceleration in time of appearance of the
thiid pair of septa. Moreover, from his own observations on
a decalcified silicified specimen of Streptelasma profundum
(Owen), he presents what he considers as evidence in support
of a primary tetramerism. He concludes “ that the primitive
condition of these [primary] septa in the Rugosa is not yet
settled,’ and that exception must be taken to my statement
that “studies on the septal development of extinct Paleozoic
corals reveal that in these early Sorms the primary septal
plan was hexameral like that of mo@rn forms.”
These assertions of Gordon are so opposed to what I hold
to be the truth with regard to the Rugosa that it becomes
necessary to re-open the question. The problem is one of
greatest importance if we are to arrive at a proper appreciation
of the phylogenic relationships of the Rugosa.
Since the appearance of my first paper I have obtained
much additional evidence in support of my contentions,
and I shall attempt to show that Gordon’s assertions are
not warranted by the evidence he submits. In the first
place, it must be admitted that the figures of Lopho-
phyllum given in 1902 are unsatisfactory, from the fact that
the microscopic sections upon which they were founded
where not all taken from the same individual coral.
Exception might be taken to their representing the actual
development of the septa, while the stages depicted are not
always those best adapted for illustrating the sequence. In
my later investigations I have pursued a different method of
study, the results from which are far more reliable than those
obtained from the old method of sections. In preparing
separate sections much loss of material is entailed, only a few
sections can be obtained from any one corallum, and the
Morphology of the Madreporaria, 229
individuality of the septa is somewhat uncertain owing to
possible loss of orientation. To remedy these defects a
method was devised by which, with suitable material, one
can follow step by step all the developmental stages from
beginning to end without any uncertainty of orientation, and
secure drawings of all desirable stages. The process involves
the grinding down of an individual fixed corallum from one
end to the other, and the study and drawing of all the stages
as revealed. The broad end of acorallum is first ground
smooth, and fixed by Canada balsam to a glass slide, in the
manner usually followed by geologists in preparing micro-
scopic sections of rocks; grinding down with fine emery or
on a ground-glass plate is then commenced at the opposite
end, the narrow tip, and continued all the way. With
favourable specimens the septa can be most clearly recognized
under a low power of the microscope, and their arrangement
outlined by the aid of a camera lucida. The distinctness of
the septa can be often emphasized by etching the exposed
surface with a little weak acid, and to secure the best
reflection of the light from the ground surface while drawing
the latter may be smeared with weak glycerine or balsam.
By these devices the whole septal development of a simple
corallum can be followed almost as satisfactorily as if one had
watched its actual growth day by day. It was from such a
series that the ten stages representing the septal development
of Streptelasma rectum given in the paper on the Fossula
were secured, and also the series here reproduced (figs. 1-8),
depicting the septal development of Lophephyllum proliferum,
and intended to replace those given in 1902.
For purposes of the present paper it is not necessary to
describe the sections of Lophophyllum at greater length than
is given in the explanation to each. They reveal nothing
fundamental beyond what was brought forward in the first
aper, but a confusion in the latter of main and counter septa,
alluded to by Gordon, is corrected. In place of the older
terminology I think the time has come to adopt that founded
upon more modern knowledge of the relationships of the
group and accepted for the Anthozoa geneially. With the
exception of unimportant details, the septal sequence of
Lophophyllum here given bears the closest relationship to
that of Streptelasma rectum in the sixth part of these con-
tributions ; moreover, it is that found to be characteristic of
a large number of other species of rugose corals which I have
studied by the same method (cf. figs. 9-12; 13-16). Septal
and mesenterial development is unquestionably one of the
most reliable means zoologists possess for determining the

verse section immediately above the tip of a corallum. The lines of
calcification of six primary septa (protosepta) are clearly seen, those
of the two median septa being continuous. At this level all the
septa are thickened to such a degree that there are no interseptal
spaces remaining, and in such a surface view as that from which the
fizure was taken there is no indication of the boundary surfaces
between two adjacent septa. According to the accepted terminology,
the upper border is dorsal and the lower ventral.

sented by the black wedge-shaped areas, now occurs between all the
septa. ‘he lines of calcification of an additional pair of septa
(metasepta, a, a) are seen, situated within the two middle of the six
primary interseptal chambers (the counter quadrants of paleonto-
logists). The number of external ridges and grooves is double the
number of internal septa, a septum corresponding with each alternate
eroove.
. 3.—Section above that of Fig. 2. A pair of metasepta (a,, a,) has
now appeared within the two ventro-lateral of the six primary
interseptal spaces (the principal or chief quadrants), corresponding
with the metasepta (a, a) of the middle primary chambers.
.4.—A section still higher. Another pair of septa (4,4) is now
appearing within the two middle primary chambers. At first the
new septa are sharply turned towards the older septum on their
dorsal aspect and there is no interseptal space.

The fundamental contention raised by Gordon centres in
the number of primary septa characteristic of the Rugosa,
that is, whether four or six; and upon this mainly depends

the possibility of firmly establishing the relationships of the
group. ‘The ingrained idea of a primary tetrameral plan for
the rugose corals rests upon the fact that in the mature
corallite there are frequently four primary septa, which by
their greater or less size stand out more or less conspicuously
among the rest and divide the calice into quadrants; and, in
addition, it is easily seen that new septa are added at four
regions, one within each quadrant. As demonstrated in my
two earlier papers, these suggestions of tetramerism in both

A further septum (d) occurs within each middle chamber, without a
corresponding pair being added within the ventro-lateral chambers,
The central part of the dorsal directive septum is beginning to be
freed from the inner ends of the other septa, and appears something
like a columella, with distinct centres of calcification. In the space
between any two adjacent principal septa the first traces of the
centres of calcification of the exosepta (2) are now displayed, their
appearance all round the calice being nearly simultaneous. The
exosepta have thus no ordinal value, such as the principal septa or
entosepta possess ; they correspond with alternate external grooves
alternating with the principal septa.
the developing and mature corallite are not at all proofs of a
primary tetramerism ; moreover, Gordon produces no proofs
beyond a suggestive condition in Streptelasma profundum to
be discussed later. According to my interpretation, in the
Rugosa a secondary tetramerism has been impressed upon a
primary hevamerism.
At first sight it would seem to be a simple matter to
determine the number of primary septa in a corallum. It is

rarely, however, that one secures examples of these ancient
corals having perfect tips, and otherwise of such a character
that the arrangement of the earliest septa can be made out,
either from microscopic sections or grinding down. Speci-
mens of Lophophyllum proliferum, the species first studied in
this connection, are usually remarkably favourable for such
an investigation. Where, in other species, the tips are
perfect, it is often found that the septa are not determinable
until one or more metaseptal pairs have appeared, in addition

The interseptal spaces are now greatly enlarged, and all the septa are
free from each other and from the dorsal directive septum with its
columella-like free end. Exosepta regularly alternate with the
entosepta all round the calice, and the ventral directive septum is
a little smaller than the other principal septa, thus giving rise to a
fossula. The stage represented is practically that characteristic of

to the protosepta ; sometimes partial or entire silicification of
the corallum has taken place, and rendered the preparation
of sections practically impossible ; while in such as Duncanella
borealis the original tip is wanting, and when first collected
four, five, or six pairs of septa are frequently exposed to
view (fig. 17).
Since the publication of my first paper I have made con-
siderable efforts to secure from various sources specimens of
234 Prof. J. E. Duerden on the
rugose corals particularly adapted for investigating this
special problem. The number now available has enabled
me to demonstrate the presence of six primary septa in

several species, in addition to Lophophyllum proliferum ; in
fact, wherever the specimens have been such as to admit of the
proseptal stage being determined six septa have been revealed.
Streptelasma rectum, Hall, is a species of which examples are
frequently obtained having perfect tips, and the whole
corallum preserved in such a way that the septal develop-
ment can be followed throughout. All the principal stages
have been described and figured in my paper on the Fossula,
and in the present connection the fact of supreme interest is
that six primary septa occur, all of equal size and situated
at equal distances apart (/. ¢. fig. 2). It may be mentioned
that in one specimen of S. rectum only five primary septa

The same number of septa occur within the middle primary chamber

were present, and the later septa were added in an order
different from that of the examples with six primary septa.
Manifestly one must be prepared for irregularities in the
septal formation of fossil corals just as much as in living
corals.
Coralla of Cyathaxonia cynodon, HK. & H., are also well
adapted for the determination of the number of primary
236 Prof. J. E. Duerden on the
septa, as their tips are usually perfect. On grinding down a
corallum for a short distance six equal septa are disclosed,
radially arranged, and separated by comparatively large equal
interspaces. On pages 234-235 four figures are given
(figs. 9-12) displaying the early stages in the septal develop-
ment of this species, starting as before with a primary
hexamerism.
In the above and other species, in which the septal con-
stitution has been established by the process of grinding, it
may be objected that if earlier stages than tliose first repre-
sented could be obtained four primary septa might then
be disclosed, and the other two would be seen to be but later
additions to a tetrameral group; in other words, that the
earliest septal stage is not that indicated as such. Were this
the case the dorso-lateral pair here regarded as protosepta
would be really the first pair of metasepta. Against this
reasonable objection it can be affirmed that in all cases as
soon as any of the primary septa are determinable they are
already six in number, all fully developed, practically equal
in size, and radially disposed at equal distances apart. ‘l'wo
pairs never appear in advance of a third pair, Moreover,
there is never any hint of the third pair being inclined at
its origin towards the others, after the manner of develop-
ment invariably characteristic of the first and later pairs of
metasepta. All the sections representing the appearance of
the metasepta indicate that the new septa first arise within
the wall of the calice. Their free end is then turned towards
the older septum dorsal to them, and as they become larger
and extend higher they seem gradually to travel, as it were,
along the older septum, until they nearly reach the middle of
the calice. The centripetal end then becomes independent
of the adjacent septum, and is either free or united in a
columellar mass. Thus the metasepta are not truly radial
until they are fully formed. ‘These stages are presented by
all the metasepta and also exosepta in their devolopment, but,
as already stated, they are never represented by any of the
first six septa. All the studies on the development of the
corallum of recent hexameral corals, conducted by Lacaze-
Duthiers, G. von Koch, and myself, indicate that six equal
septa are formed simultaneously in a radiate manner, and
such would appear to have been the case with the corals of
Palzozoic times.
Among a large collection of rugose corals lent me for study
by the United States National Museum, through the
assistance of Prof. C. Schuchert, are several specimens

very satisfactory for the present study, having perfect tips
and septa clearly displayed. Jour of the early stages are
reproduced in figs. 183-16. Here, again, on the earliest
appearance of the septa six members are present, equal in
size, situated at equal distances apart, and disposed approxi-
mately in a radial manner; the metasepta are added at four
regions in the manner just described, the newer as they
appear being inturned towards the older,

squat form, these species are not so well adapted for displaying

impossible to secure the protoseptal stage alone, yet when
the earliest stage is reached at which septa are exposed their

arrangement is such as to leave no uncertainty that the
primary condition was hexameral, and that the later septa
have been added in the same manner as in other forms where
the sequence is determinable from the beginning. Such are
Streptelasma profundum, Streptelasma wayensis, and Dun-
canella borealis (figs. 17-21).
It seems unnecessary to multiply examples. Wherever
the tip is sufficiently well preserved to display the primary
septa they are found to be six in number; in no case has
even a suggestion of a primary tetrameral condition been
encountered. With all these definite facts available there
would seem to be no longer a possibility of any reasonable
doubt as to the primary hexamerism of the Rugosa.
In his paper Gordon does not attempt to dispute the
hexamerism of Lophophyllum proliferum, but endeavours to
explain it as the result of the precocious appearance of what,
according to him, should be the first pair of metasepta.
This pair, here regarded as the primary dorso-lateral pair,
Gordon supposes to belong not to the protoseptal, but to the
metaseptal series, and owing to its accelerated appearance it
gives a false hexameral character to the primary stage.
This idea of acceleration is altogether hypothetical, and its
author does not produce a single acceptable fact in its
support. He considers that a departure from the original
_ tetrameral type is likely to occur in a form such as Lopho-
phylum which appears in Carboniferous times, that is, towards
the close of the geological distribution of the rugosids. This
argument, unsatisfactory in itself, now fails altogether in view
of the fact that comprised in the list of corals given above,
in which six primary septa have been definitely established,
there are representatives of almost all ages in the chrono-
logical extension of the rugose corals.
Gordon draws attention to the fact that in the older stages
of growth of a corallum there is no difference in character
between the dorso-lateral pair of primary septa and the
principal septa which arise later, that the interseptal spaces
between these septa and the adjacent septa differ in no ways
from the other interspaces, and that exosepta appear in the
dorso-lateral primary interseptal spaces just as in others.
Werte these really primary septa he expects that they would
present some feature distinguishing them from the later
principal septa. Such an expectancy, however, is altogether
contrary to what we actually know of development and growth
in the Anthozoa. All studies in this group, particularly among
the actinians and corals, reveal that the growth tendency is
everywhere towards a perfectly cyclic plan, with all the parts
240 Prof. J. E. Duerden on the
in any cycle alike in size and other characters; however
strongly bilateral or otherwise varied may be tlhe course of
development, the final result is an approximation towards
radial symmetry, such as is characteristic of most sessile
organisms where the environmental forces act equally all
round. Most rugose corals have an almost perfect cyclic plan
in the uppermost part of the calice, though we know that this
is founded upon decidedly bilateral developmental stages ;
likewise the cyclic disposition of the organs in the adult
stages of nearly all actinians and corals gives scarcely any
hint of their strongly bilateral developmental sequence.
Hence any argument as to the primary or development
relationships of the septa founded upon adult appearances
has little or no value.
Gordon errs with Kunth and others in assuming that each
of the external grooves on the surface of a rugose corallum
represents a septum formed in orderly sequence within each
quadrant (see Gordon’s fig. 15). As a matter of fact only
alternate grooves correspond with principal septa (entosepta),
and it is these alone which have any sequence value. This
is manifest from the series of sections represented in figs. 1-8.
In figs. 1-6 only entosepta are yet present, and correspond
with alternate external grooves, while figs. 7 and 8 show
that the smaller septa (exosepta) arise almost simultaneously
at a rather late developmental stage, and are thus of no
significance as regards septal sequence.
Attention may now be directed to the proof which Gordon
has to offer in support of his contention that the primary
septal plan of the rugosids is tetrameral. He fully recognizes
the difficulties attendant upon securing sections through the
tips of the coralla, and apparently has not succeeded in
obtaining such; for the only evidence he adduces rests upon
a couple of decalcified silicified specimens of Streptelasma
profundum, one of which was broken during examination ;
with such material study must necessarily be limited to
surface views. He states that “of the four primary septa
represented in the drawing [J. c. fig. 16], the counter septa
extended farthest down, the cardinal next, and the alar
next,” and claims that these four septa extended farthest
down into the base of the calice and are the only true primary
members.
I likewise have in my possession about a dozen decalcified
specimens of S. profundum, of all sizes, which present all the
appearances described by Gordon, and in some the earlier
stages are more completely preserved than Gordon’s figures
and remarks indicate his two examples to be. 1 have already

figured the septal plan of one of these young forms (Biol.
Bull., June 1905, p. 39). The figure shows that in this
particular specimen the details of the early septal growth
are so well preserved as to display the septa turned towards
one another in the regular manner revealed by serial sections,
but suc! are not indicated in Gordon’s drawings; the exo-
septa can also be seen in their initial relationships with the
entosepta, which is likewise not the case in Gordon’s example.
Gordon himself suggests that absorption has taken place in
the lower parts of the septa of his specimen, and in the case
of the tertiary septa (eosepta of the present paper) acknow-
ledges (p. 124) that ‘‘it was impossible in all cases to tell to
what length they extended down into the coral.” His own
figure and statements would prove that even the primary
septa were not all formed at the same time, though such is
certainly the evidence from all well-preserved material of
other species. ‘Taking into account all the details which
Gordon offers, and studying along with them my own much
better series of the same species of coral, I am convinced
that little or no value can be placed upon his specimen as an
aid in solving the present problem. Moreover, I consider
that the evidence from none of my specimens could be
regarded as conclusive as far as concerns the number of
primary septa; to a certain extent the actual details would
for ever remain a matter of individual interpretation.
Assistance from decalcified silicified specimens must, in my
opinion, always be unsatisfactory, largely on account of
possible imperfect silicification of the earliest stages. ‘The
details obtainable from sections or grinding of the actual tip
afford by far more convincing evidence, and manifestly, from
the additional evidence produced in this paper, there is no
occasion for any uncertainty in the matter; there can now
be no reasonable doubt that the hexameral plan is that
characteristic of the group.
To sum up, Gordon, in my opinion, (1) has failed to pro-
duce any evidence in favour of a primary tetrameral plan in
the rugosids, and (2) his attempt to explain the hexameral
character of Lophophyllum proliferum as resulting from
precocity of the first metaseptal pairs is altogether unsup-
ported by facts. The demonstration of six primary septa in
many other species is proof beyond doubt that L. proliferum
is not exceptional in its hexamerism, but conforms to the
rugosid type.
Gordon is not in a position to discuss the view that the
Rugosa find their nearest modern representatives’ in the
Zoantheze. One of the necessary arguments for the main-
243 Dr. F. C. Wellman on
tenance of this is the establishment of their primary hexa-
merism, and unless very weighty evidence to the contrary
should be forthcoming this must now be regarded as
accomplished. ‘lhe facts in support of the relationship may
be summarized as follows :—
1. The Rugose corals and the Zoanthid actinians have both
a primary hexamerism.
2. The septa in the Rugosa and the mesenteries in the
Zoanthez are added in bilateral pairs at only one region, a
vertical zone within the primary exoceeles, there being four
such regions—middle and ventro-lateral chambers—in the
Rugosa, and two—ventro-lateral chambers—in the Zoanthee.
3. The septa in the Rugosa and the mesenteries in the
Zoanthee are never polycyclic, as in modern corals and
ordinary actinians ; at most there are only two cycles of
septa, large entosepta and small exosepta, disposed in such
a manner as could only have been produced in polyps with
a mesenterial arrangement similar to that of the Zoantheex.
4. The presence of a ventral directive fossula in the
Rugosa, usually persisting in the fully developed and other-
wise perfectly radial calice, can be explained by the
occurrence within the living rugose polyp of a single ventral
siphonoglyph or gonidial groove, such as is characteristic of
zoauthid polyps.
XXXV.—Notes on the Habits of Tsetse-flies.
By F. Cret@Hton WELLMAN, Benguella, West Africa.
HAvinG recently had opportunity to make some observations
on tsetse-flies in the Esupua “ fly- belt,” about thirty-five miles
inland from the seaport town of Benguella, West Africa, L
present here some of my findings. Our knowledge of these
flies is as yet very far from complete, and first-band observa-
tions, including mention of the date, habitat, and species
studied, should be recorded.
The following notes were a few of them made in November
1904, but most of them date from October 28th and 29th and
November 9th and 10th, 1905. The Esupua “ fly-belt” is,
as I have said, about thirty-five miles inland from the port of
Benguella (13° 8S. on the west coast of Africa) and twenty
miles from the city of Catumbella. The fly studied by me is
a subspecies of Glosstna palpalis, Robineau-Desvoidy, which

was last year described in the Ann. & Mag. Nat. Hist. as
Glossina palpalis Wellmani, Austen (1905) *,
Although the district in which the flies were taken was
found to contain some game, including eland (Oreas canna
Livingstonei), roan antelope (//ippotragus equinus), kudu
(Strepsiceros kudu), the duyker (Cephalolophus Grimm?) , and
Speke’s tragelaph (Limnotragus Speket), yet I believe that
human blood forms the greater part of their food. This is
undoubtedly true over at least a part of the “belt.” Along
the north bank of the lower Katumbela River from Esupua
to a point half a day’s march up the river lies the great
Benguella caravan-route, near which there is little or no
game, but over which constantly pass great caravans of half-
naked Bantus. At Esupua one may see half a dozen of these
large caravans camping in one place. It is here that the flies
are the most plentiful. ‘They hide in the tall grass and
sedges near the river, and also on stones, trunks of trees and
vines, and among the leaves of shrubs and bushes on the
bank. When a native is sent to the river for water the flies
rise from their resting-places as he passes and follow him,
seeking for an opportunity to bite. On several different
occasions I followed natives going to the river to fetch water,
One of these I saw bitten twice, three were bitten once each,
and seven I did not see bitten at all. The Bantus say that
the bite is painful, and I noticed that if a fly settled on a
porter’s back the man generally slapped himself as it began
to insert its proboscis. Some of the specimens I took had
abdomens greatly distended with biood. The flies do not
always remain so close to the river. ‘The first one I saw in
November 104 was between three and four hundred yards
from the river in thin ‘ desert” bush, consisting of Acacia
refeciens and other thorny shrubs, which afford practically no
shade. Gl. palpalis Wellmani certainly does not share the
dislike for human ordure which has been ascribed to its
congeners. I have frequently seen it in and around the
filthiest native camps at some distance from the river and
from shade, where it had evidently gone for the purpose of
sucking human blood. ‘The fly bites most viciously during
the heat of the day, and, as I have said, goes considerable
distances in search of food. It bites less readily in the
evening and early morning. The native blacks claim that it
occasionally bites at might. ‘The one observation that [
made in view of this statement leads me to suspect that it is

not true, at least for the time of year mentioned at the
beginning of these notes. All three of my visits to Esupua
were made during the heaviest rains of the year, which,
according to native reports, do not seem to have the effect
which has been claimed for them in reducing the numbers of

is unfortunately on the increase in Benguella District.

1901-1902.’ By Philip Lake, M.A., F.G.S.
Several horizons are represented by these fossils. Two speci-
mens of Peltura, probably from the Upper Lingula-Flags, were
collected at Cochaiya, about 3 miles north-east of Pata. New
species of Symphysurus and T'rinucleus, probably of Arenig age,
were found about a mile from Apolo, Province of Caupolican. An
indeterminable species of Oyy sia was obtained from the right bank of
the River Caca, in the same province. Phacops cf. arbuteus, Dal-
manites Puituna, and D, Muecurua were collected in the track
from Apolo to San José de Chupiamonas, also in the province of
Caupolican. The nodules from which they were derived are
probably of Lower Devonian age. Descriptions are given of the
new species and other forms mentioned. It is worthy of remark
that, while the earlier forms show affinities with the contemporaneous
European fauna, the Devonian species are much more closely allied
to those of South Africa and North America.
2. *Graptolites from Bolivia, collected by Dr. J. W. Evans in
1901-1902.’ By Ethel M. R. Wood, D.Sc.
In black pyritic shales from three localities several specimens
of Didymoyraptus were collected : one referable to bifidus, one of the
type of affinis, and one of the Nicholsoni-type. Phyllograptus,
Glossograptus, Cryptograptus, and Diplograptus were also obtaine },
A pale, silky grey shale shows also rare graptolites, belonging to a
species comparable with Climacoyraptus confertus. These forms
indicate that both the black and the pale shales belong to horizons
in the Upper Arenig rocks (Lower Llanvirn of Hicks).

This is another instance of the same species occurring in
the Indian and Atlantic Oceans. ‘The only slight difference
between the shells from the above locality and those obtained
by the ‘Challenger’ Expedition in the West Indies in
390 fath. is that the slit is perhaps a little nearer the apex in
the Manar shells than in those from Culebra Island.

The single very slender specimen from Station 331,
although 80 mm. in length, is only 6 mm. at the broadest
diameter. This results from its perfect growth from the
very young state, the young shell not being broken as is
generally the case in these large Dentalia. “It tapers to a
point less than a millimetre broad, and exhibits in the usual
position a very fine slit 4 mm. in length. The examples
from Station 283 are quite like the original type from off
Colombo.

The distinguishing feature of this species is the peculiar
fine serration of the fine riblets, especially those upon the
concave curve of the shell. Probably this character would
be lost in worn specimens. Judging from the gradual
tapering of the shell, 1 do not think it would attain much
larger dimensions than those here given. The fine decus-
sation of the surface is only observable in well-preserved
examples. The riblets number sixty to sixty-six at the larger
end and about thirty at the narrow extremity. Only one “of
the two specimens exhibits a slight terminal notch, but
probably the young shell would have a narrow slit. The
curve of shell is different in the two examples at hand, one
being straighter than the other.

The greater part of the surface of this interesting shell is

radiating series of granules or small pustules. The extreme
tips of the umbones are smooth, then comes a small defined
umbonal cap with about nine ‘plain radiating riblets, after
which commence the rows of granules. ‘hese are as broad
as, or even in some cases broader than, the grooves between
them. On the anterior slope they become ridges rather than
rows of pustules and are at right angles to the margin of the
valves. ‘They are also very much of the same character on
the lunular slope.

Hab. Station 248, W. of Travancore, 224-284 fath., sand.
The sculpture of the two valves in this beautiful species is
altogether different, that of the right valve, which is a little
flatter than the left, consisting of very delicate and close-set
regular lamelle or strize, whilst the left valve has numerous
fine radiating riblets, which are minutely squamose through
being crossed by the very fine concentric lamelle. The
internal riblets, ten in number in each valve, do not reach to
the margin, and those of the left valve are a little finer than
those of the right. The colour of the valves is also different.
The deeper valve is more or less orange-tinted within and
without, whereas the right valve is almost white, with only a
trace of colour on each side towards the dorsal slopes.

The valves are fairly strong up to the ends of the radiating
lire, but beyond that point they become very fragile and
easily break away. The concentric fine lamellz are very
similar in both valves, but the left valve, which is gently
convex from the umbo to the opposite margin, also exhibits
fine radiating lire. These, however, gradually disappear
about the middle of the valve, so that only the upper half of
the surface is cancellated. The auricles, of which the ante-
rior are a trifle larger than the posterior, exhibit fine lines of
growth and a few radiating threads also, excepting the hinder
auricle of the right valve, which hardly shows any trace of
this radiating sculpture. The frout auricle of the same valve
is bounded below by a narrow groove at the byssal sinus.

The presence of hinge-teeth, as described by Mr. Melvill,

at once removes this species from Cryptodon, which is eden-

The two specimens from the above lozality and those
already recorded in the ‘ Annals’ are not quite identical with
Deshayes’s type. They have a few more ribs, the sulci
between them are not quite so deep, and the nodules on the
cost are closer together. However, I am of opinion that a
more extended series of specimens would show that these
differences were not of specific value.

its South-African congener. The outline is very similar,
the radiating microscopic striation is the same, the strength
of the coste, the character of the lunule, the escutcheon, the
hinge, the scars, and the crenulation of the edge of the valves
are all very much alike in both forms.

XXX VIT.—WNotes on the Genus Otomys-
By R. C. Wrovearon.
Tue material available to me for examination in the collec-
tion of the Natural History Museum amounts to about
150 specimens (skins and skulls) from some 30 localities.
Though Africa north of the Equator is very poorly repre-
sented, yet, at first sight, the total material seems sufficient
for a fairly exhaustive classification ; but, on careful com-
parison, I am convinced that this is not so, and that the area
south of the Zambesi, which is especially well represented by
series from many different localities, is just that in which
the results I have obtained are the furthest from finality.
All but two species of the genus have the anterior molar
in the lower jaw composed of four laminz or their equiva-
Jents. Setting aside for the moment these two aberrant forms
as Section III., the genus may be easily further divided into
two sections, according as the lower incisors are smooth (or
but faintly grooved), or are markedly grooved ; and each of
these Sections falls again naturally into two groups. In
Section I., comprising the forms with smooth lower incisors,
those in which the posterior molar in the upper jaw is
composed of four lamin (or their equivalents) and large
bulle form the Brantst group, and those in which m* is
composed of five Jaminze and the bull are quite small form
the unisulcatus group. In Section I]., comprising the forms
with grooved lower incisors, those with a single groove as in
irroratus, Brants, are readily separated from those with a
double groove as in Jacksoni, Thos.
The geographical distribution fairly closely agrees with
these main divisions of the genus. Thus Section I. is found
in a strip of country running across 8. Africa between 28°
and 32° 8. lat. Of Section II. the Jacksoni group is found
the Genus Otomys. 265
north of the Equator, while the irroratus group inhabits the
whole eastern half of the continent from Cape Town to the
Equator, the forms south of the Zambesi showing normally
six laminz in m*, with about 5 per cent. of exceptional
individuals having seven laminze, while those north of that
river show exactly the reverse. ‘The western half of Africa
is unfortunately unrepresented in the collection, so far as
Section IL. is concerned, except by a single specimen from
Angola and askull from the Cameroons, both showing seven
laminee in m’. This would seem to show that the rule of
seven laminze in m’ in the northern forms holds good also of
the west coast. But the Angola specimen probably reached
that country vid the Congo Valley (the common Otomys
of Angola seems to be the aberrant Anchiete of Bocage), and
therefore is no indication of the truly indigenous fauna of
western South Africa.
I arrange the forms I have been able to distinguish in a
key as follows :—

Srcrion I,
The forms in this Section, as will beseen from the key (A. a’),
are characterized by the smooth lower incisors and, in most
cases, the modification of the anterior two laminz of m,. The
exact structure of the molars of Ofomys has never, I believe,
been worked out. It is not, therefore, certain whether the
modified portion of m, in this Section represents one or two
laminze ; but in view of the almost universal presence of four
lamin in m, throughout the rest of the genus, and the fact that
Sloggetli, which undoubtedly belongs to this Section, has four
complete lamine in that tooth, I have accepted the proba-
bility that the modified area represents two laminz. This
modification takes two forms, which, in well-marked cases,
are quite distinct and cannot have been produced the one
from the other by wear. In both forms the inner ends of
the two anterior lamine are produced in a curve, the ante-
rior backward and the posterior forwards, and fused into one
continuous strip of enamel in the shape of a horseshoe with
the open end outwards. In what I have called the “ kidney ”’-
shaped form the two free ends of the horseshoe are doubled
inwards, showing a heart-shaped or kidney- shaped pattern ;
in the ‘spiral ”’ form the free end of the posterior lamina is
not or scarcely produced, while that of the anterior is
produced boldly inwards and again doubled on itself, thus
showing a distinct spiral pattern.
These forms of modification, though one form is found
in a large majority of individuals of a given species or
subspecies, are not quite constant, and I have therefore uot
relied upon them in my key.

4, 2.3.81-88. Klipfontein &c., Namaqualand. (Rudd
Exploration.)
The type is very young and immature, and although it
seems In some respects to ‘resemble suspiciously the eastern
form, still, all things considered, I am constrained to agree
with and follow Thomas (P. Z. S. 1904, vol. 1. p. 178) in
268 Mr. R. C. Wroughton on
accepting the Namaqualand series as quoted above as topo-
types of true Brantsi.
From this series I deduce the following as normal dimen-
sions of this species :—
Head and body 150 mm.; tail 100; hind foot 28; ear 17.
Skull: greatest length 38; basilar length 31; zygomatic
breadth 20; length of upper molar series 8; bull 11.
Smith describes the colour as “. . . . sienna-yellow varie-
gated with black or umber-brown”’—a fairly exact description,
only that the sienna-yellow fades to white except in the
central dorsal area, 7. €. in a band, from the nose to the base
of the tail, about as wide as the ears are apart. The indi-
vidual hairs are all slate-coloured basally, the majority being
broadly tipped paler; this pale tip is white except in the
central dorsal line, where it is tinged with brown; the
minority are black-tipped. The belly, as stated by Smith, is
pale grey.
All the individuals from Klipfontein, without exception,
show the modification in the “spiral” pattern of the two
anterior laminze of m,, as also does 7646, the second of
Smith’s specimens. On the other hand, Smith’s specimen
158 a (skull 764.c), selected by Mr. Thomas (J. ¢. supra) as
the type, shows a modified form in which the inner end of
the anterior lamina is produced into the “ spiral” form, but
the inner end of the penultimate lamina is also slightly
produced and doubled inwards as in the “ kidney” pattern.
One specimen only (98. 9.6.1, received from the Cape Town
Museum, and labelled “ Namaqualand’) shows a distinct
“‘ kidney ” pattern.
Both Brantsi and its subspecies luteolus, forming group 1
of this Section, are easily distinguishable from group 2 by
the huge bullz and m’* composed of the equivalents of only
four laminee.
(2) Otomys Brantsi luteolus.
Otomys Brantsi luteolus, Thos. & Schw. P. Z. S. 1904, i. p. 178.
1.7.9. 28-29. Deelfontein, C.C.
2.9.1.35-47. Deelfontein, C.C. (Col. Sloggett).
3.1.4.42. Deelfontein, C.C. (Col. Sloggett).
This form differs from true Brantsi in its darker, more
brownish fulvous colouring (the whole upperside being tinged
with brown, and not only a dorsal band as in Brantsi, and
the brown is much darker than in that species), shorter hind
foot, and shorter upper molar series,
the Genus Otomys. 269
The following may be taken as normal dimensions for this
species :—
Head and body 145 mm.; tail 80; hind foot 25; ear 17.
Skull: greatest length 38; basilar length 30; zygomatic
breadth 20; length of upper molar series 7; bull 11.
In all the individuals of this subspecies, quoted above, the
modification of the first two laminz of the anterior lower
molar shows distinctly the “ spiral” pattern.
(3) Otomys unisulcatus.
Otomys unisulcatus, Cuvier, Mamm. 1829, pl. cclxiv.
41.805, 41.806 (skull 59.5.7.2). S. Africa (Dr. A.
Smith).
There is unfortunately no really satisfactory specimen of
unisulcatus in the Natural History Museum collection. It
is probable that the above are the specimens on which
Dr. Smith based his description of unisuleatus (Zool. 8S. A.
pl. xxiii.). Basing on these and on this description, the
following may be taken as normal dimensions of this
species :—
Head and body 175 mm. ; tail 90; hind foot 25; ear (no
data).
Skull: greatest length 38; basilar length 30; zygomatic
breadth 21 ; length of upper molar series 8.
The shorter tail and hind foot and a-much warmer
colouring seem to be the chief characters distinguishing this
species from wnisulcatus Broomi, while its larger size and much
shorter tail differentiate it from unisulcatus Granti.

The normal dimensions for this species are :—
Head and body 160 mm.; tail 105 ; hind foot 28; ear 24.
Skull: greatest length 38; basilar length 31; zygomatic
breadth 18 ; length of upper molar series 8; bull 8.
This form differs from typical wnisulcatus by its paler, less
rufous colouring and its rather larger hind foot, ears, and
270 Mr. R. C. Wroughton on
bulle, and from unisulcatus Granti in addition it differs by
its larger size.
The modification of m, shows a close approximation to the
spiral pattern even in the younger specimens. m* is quite
as in wnisulcatus.
Mr. Thomas described this form as a distinct species, but
I do not think it should rank as more than a subspecies ot
unisulcatus, to which it is quite as closely related as Granti.

The type is a very old male; more normal dimensions
than those given by Mr. Thomas are as follows :—

Skull: greatest length 37; basilar length 30; zygomatic

The only well-marked character distinguishing this local
race from true wnisulcatus is the obsolescence of the grooves
on the upper incisors, and therefore the Fish-River specimen
must be placed here.
The modification of the anterior portion of the first lower
molar in the younger specimens shows the “ kidney ” pattern,
but in older specimens it seems to approximate to the spiral
pattern owing to wear. The third upper molar is quite as in
unisulcatus—i. e. is composed of three distinct lamine and a
posterior portion in the form of a trefoil.

Secrion II.
The forms of this Section are easily distinguished from
those of the last by the grooving of the lower incisors, and
the two groups of the section from one another by the
character of this grooving. Group 1, with forms which
have only one deep groove in the lower incisors, comprises
the larger number of the individualsin the genus. As usual
in the classification of the mammal fauna of 8S. Africa, the
species (trroratus) representing Group 1 can be broadly
divided into two forms inhabiting opposite sides of the
Zambesi River. Individuals from localities south of the
river are found to have an m* made up of six lamine, but
in about 5 per cent. of the specimens in the Natural History
Museum are found seven lamine; in specimens from north
of the Zambesi exactly the converse is found to be the case,
except only in the case of the very high-level form from
Mount Kenya, which at the northern limit of the species
has uniformly six laminz, and the Ruwenzori form Denti,
which has only five. Some such geographical division of the
species is also indicated by the colouring, the southern forms
being black speckled with white, while the northern sub-
stitute a brown for the white of the southern forms. It
is in dealing with the 8.-Zambesi form of irroratus that I
have found that, notwithstanding the very considerable
quantity of material available for examination, it is all too
small for any really satisfactory result to be arrived at. So
far as skull-characters go, the whole species seems to be in an
unstable condition. I have failed to find in the southern
specimens a single series in which any one distinctive
character is really constant. I have already said that the
lamine composition of m* presents exceptions to an other-
wise general rule. In size there is similar variation:
specimens (quite mature) from Cape Town, De Kaap, Trans-
vaal, &c., show a greatest skull-length of 36 mm.; others,
from King William’s Town, Kuruman, &c., show 44 and
even 46 mm.; while the normal size is 40-41 mm. Similar
in-and-out variation could be shown for almost any character.
Under the circumstances I have decided to leave all these
forms under irroratus, only distinguishing, south of the
Zambesi, a couple of colour-forms as subspecies.

Brants’ description is a long one, but does not furnish any
strikingly characteristic characters, and gives no type locality.
The upper incisors have one deep groove towards the outer
edge and a shallow inner one, and the lower incisors one
deep groove. ‘The dimensions given are :—Head and body
222 mm., tail 100. Allowing for the exaggerated measure-
ments (according to the method of taking these measurements
at the present day) of the head and body, the following may
be taken as normal dimensions of irroratus :—
Head and body 180 mm. ; tail 100; hind foot 29; ear 23.
Skull: greatest length 41; basilar length 32; zygomatic
breadth 20; length of upper molar series 9; bullz 7.
The colouring is black, with a minute speckling of very
pale buff, the belly grey. m° is composed normally of six
laminz, but in isolated cases, without any rule as to size,
age, or locality, seven lamine are found.

The colouring is like that of the northern forms, i. e. the

Alt. 8000’. (Type B.M. no. 2.1. 6. 22, a fully adult 9.)
A large Otomys with the characteristic dark brown
colouring of the northern forms. Unfortunately the
dimensions were not recorded by the collector and the
skulls are much broken, but the following may be accepted
as the dimensions of the species :—
Head and body 175 mm. ; tail 90; hind foot 30; ear 21.
Skull: greatest length 42; basilar length 34; zygomatic
breadth 20; length of upper molar series 9; bull 7°5.
The size is much as in typical irroratus, but the warm
northern colouring distinguishes it markedly from this species ;
the southern form cupreus which resembles it in colouring
is much smaller. From its more immediate neighbours it
may be distinguished, from nyzke by the shorter hind foot,
much broader, flatter, nasals, and the much smaller bullz of
that species, and from ¢ropicalis, which it resembles in size
and length of hind foot, by its narrower, stouter skull, rather
wider, compressed nasals, and rather larger bulle.

Thomas in his description quotes from the collector’s
label 195 and 93, for the head and body and tail measure-
ments respectively, but I am confident there is some error in
these. It is, in fact, a rather short-tailed Otomys of about
the size of typical aroratus, and I therefore give as normal
dimensions of this species :—
the Genus Otomys. 275
Head and body 180 mm. ; tail 80; hind foot 30; ear 23.
Skull: greatest length 44 ; basilar length 35 ; zygomatic
breadth 22; length of upper molar series 9; bullee 7°5.
In addition to the characters recorded by Mr. Thomas, a
subterminal compression of the nasals is most marked, and
with the generally narrower nasals serves to distinguish
tropicalis from angoniensis at a glance. The Mianzini series
shows this compression of the nasals very strongly, and the
brain-case is even broader and deeper than in the specimens
from Mt. Kenya; but the skins seem to belong to a much
smaller animal and, moreover, vary a good deal in colour.
No measurements, however, were recorded by the collector ;
I therefore reluctantly place them under this species.

Skull: greatest length 37 ; basilar length 30; zygomatic

The presence of only five laminze in m’ is sufficient to
distinguish this from any other member of the northern
group or, indeed, of Section II.
Mr. Thomas has described this form as a species, but as
I have ranked all the other forms as subspecies of irroratus
I feel it more convenient to treat Denti in the same way,
notwithstanding the lamin formula of m’. '

any of its neighbours.

The extraordinarily broad, flat, spatulate nasals serve to
separate at once this from all other forms.

doubt. The dimensions recorded by Mr. Thomas for Degeni

The two aberrant species in this Section seem to be found
isolated in the midst of normal forms: /aminatus has been
taken only from Sibudeni, Zululand (and, it is stated, from
a locality in Pondoland), and we have quite normal irroratus
from the same place; Anchiete is recorded by Bocage from
Caconda, &c., Angola, and has not been found elsewhere
outside Angola ; while we have a specimen from Braganza
which is apparently a normal irroratus, and Bocage records
several other localities in Angola in which irroratus has
been found.

This is the largest form so far recorded in the genus; it
is larger even than the biggest ¢rroratus from Kuruman both
in body and skull dimensions, yet the Kuruman specimens
are very old, while the specimens of Anchiete though mature
are not by any means old. But for its aberrant m,
Anchiete would fall ito Group 1 of Section II., 7. e. the

XXXVIII.—On the Genus Cercocebus, with a Key to the
known Species. By R. I. Pocock, F.LS., F.Z.S.,
Superintendent of the Zoological Society’s Gardens.
In Trouessart’s Cat. Mamm., Suppl. p. 15 (1904), the
described species and subspecies of Cercocebus are referred to
two subgeneric groups, Cercocebus (s. s.) and Leptocebus.
The latter name appears here for the first time in literature
to replace Semnocebus, Gray (nec Lesson), restored by
Mr. Lydekker for C albigena, Gray, on the strength of the
blackness of the eyelids and the presence of an upstanding
crest on the crown of the head. Although considerable
latitude in opinion as to what constitutes a generic or sub-
generic character must be allowed, there seems to me to be
no particular reason for regarding elongation of the hairs on
the crown as of higher systematic value than elongation of
those on the brow, the cheeks, or the end of the tail, features
which, happily, no one has as yet claimed to be more than of
specific importance within the group.
As for the whiteness of the eyelids, this is most pronounced
in the western species (C. lunulatus, ethiopicus, fuliginosus),
much less marked, or, according to Mr. Lydekker himself,
sometimes absent, in specimens referred to C. Hagenbecki,
and also, according to the same author, absent in C. albigena
Rothschildi. Moreover, in C. congicus and C. Hamlyni the
eyelids are white, and, at least in C. Hamlyn, whiter than
the skin of the face. Yet these two species are certainly
more nearly related to C. albigena Rothschildi than to any
one of the three typically white-eyelidded species.
the Genus Cercocebus. 279
It was formerly held, even by authors familiar with C. ful?-
gtnosus, that uniformity in the colour of the hair, or, to be
accurate, the absence of the subapical pale annuli so common
in the hairs of Cercopithecus, was characteristic of the genus
Cercocebus, yet in C. fuliginosus there is a patch on the
crown of the head due to a broad yellowish area on the hairs
of this region; and since the discovery of C. galeritus,
C. agilis, and C. chrysogaster, speckled species all three, it
has been tacitly admitted that the absence of the speckling
has only a specific importance.
So far, then, as the colour of the hair and of the eyelids
is concerned, a gradation may be traced between the species
debarring generic or subgeneric subdivision even on the part
of those wishing to attach such weight to the particulars in
question; and it appears to me there is just as much or as
little reason for regarding the elongated whiskers of C. con-
gicus, or the brow-fringe of typical C. albigena, or the long
and parted scalp-hairs of C. galeritus as supplying a basis
for subgenera as for considering the crown-tuft of C. albigena
to have that value. The truth j is, if the genus Cercocebus be
divided into subgenera at all, it may with as much justifica-
tion be split into three or four as into two. But since no
beneficial end is, in my opinion, served by giving subgeneric
names to isolated species or groups of species in so small and,
comparatively speaking, homogeneous a genus as Cercocebus,
and useful names are thereby put out of court for other
nomenclatural purposes, I propose to regard Leptocebus as a
genuine synonym of Cercocebus *.

ton, in Anderson’s Mammals of Egypt, p. 15 (1902).
* The pity of introducing new names like Leptocebus into a catalogue
compiled by an author who cannot claim an intimate acquaintance even
with all the genera, much less with all the species he records, is well
exemplified by the case under consideration; for one of the alleged
species, Hayenbecki, figures in the subgenus. Cercocebus, and another,
agilis, in Leptocebus ; yet the two names were in all probability applied
to specimens only subspecifically distinct from each other.

In Trouessart’s Catalogue (1904) and, I believe, in all
previous literature this species figured as ethiops, Linn. ; but
since, as Mr, de Winton pointed out, this name was originally
given to a species of the genus Cercopithecus, it cannot
stand for the mangabey in question, for which Junulatus
seems to be the correct title.

I have seen a few living specimens of this species, but
Mr. Rothschild has kindly afforded me the opportunity of
examining the type, which lived for about one year in the
Zoological Gardens. ‘This may account for certain discrep-
ancies between the description and the specimen. Between
the drawing up of the description which was published on
Aug. 20th, 1900, and the death of the specimen in February
1901 certain colour-changes must presumably have taken
place in the hair, for it is asserted that the speckling disappears
on the flanks and outer sides of the limbs, which tend to
slate-grey, and that the inner surface of the limbs is rather
paler than the outer surface. In the specimen at the present
time the flanks and outer sides of the limbs down to the
hands and feet are distinctly speckled, though not so strongly
as the head and back, and the inner surface of the limbs 1s
orange like the lower surface of the head and body, though
paler. The describer’s statement’ that this species differs
from all other species of Cercocebus as well as from all species
of Cercopithecus in the bright orange coloration of the under
surface was made in forgettulness of the fact that Pousargues
had already ascribed a similar coloration to the belly of
the Genus Cercocebus. 281
Cercocebus agilis, and that Cercopithecus Wolf, Grayi, pogo-
nius, and nigripes have been known for many years to be so
coloured below *. My only reason for commenting now on
the fact is the great interest attaching to the similarity in the
colouring in the lower parts in all these monkeys, which
inhabit, broadly speaking, the same area of tropical West
Africa, namely the Congo. There must be an explanation of
this, but I am unable to suggest what it may be.

Loc. Upper Congo: exact area unknown.
I am indebted to Mr. Rothschild for the chance of seeing
the type of this species. On the forehead, rather less than an
inch behind the brow, there is a very conspicuous parting,
whence the hairs radiate, those directed forwards forming a
conspicuous postsuperciliary fringe. ‘This important feature,
attesting close relationship between C. Hagenbecki and
C. agilis, is not mentioned in the description and only im-
perfectly suggested in the figure. The prevailing colour is a
smoky grey above, relieved on the head, whiskers, neck,
shoulders, and fore part of the back by the yellowish annula-
tion of the hairs. These annuli practically die out on the
sides of the body, the outer sides of the legs, and on the tail,
which is merely indistinctly speckled in its basal portion
above. The throat, chest, belly, and the inner sides of the
limbs are dirty greyish white. ‘There is a complete absence
in the hair of the brown or fawn or rusty yellow hue men-
tioned by the two principal describers of C. agzlis. It is
solely on this account that I separate the two forms specifi-
cally, although strongly suspecting they will ultimately prove
to beat most merely local races (that is to say, subspecies) of
one and the same species. But of this there is as yet no
proof.
According to Mr. Lydekker, the eyelids were black in the
living type specimen, whereas another example living in the
Gardens at the same time had them flesh-coloured. In the
living specimens I have seen they are neither flesh-coloured
nor black, but somewhat greyish—that is to say, decidedly
darker than in C. ethiopicus, for example. I suspect they
are pale in the young and gradually darken with age.
* The rufous belly of C. erythrogaster must also be remembered in
this connexion.
282 Mr. R. I. Pocock on
In the speckling of the coat and the appearance and
gradual extension of the yellow of the underside a gradation
may be traced in the order named between C. fuliginosus,
FHagenbecki, agilis, and chrysogaster, whereas in the direction
of growth of the hairs on the head C. chrysogaster resembles
C. fuliginosus.

Le Naturaliste, 1897, p. 9.
Loc. French Congo: confluence of the Oubangui and the
Congo; ‘ Poste des Ouaddas” (according to Pousargues).
The specimen, now in the Paris Museum, to which Riviére
gave the name Cercocebus agilis, without adequate diagnosis,
was subsequently deseribed by both Pousargues and
Trouessart. I have not seen any specimen which exactly
fits the descriptions, though the latter apply pretty closely to
mangabeys we commonly receive from the Congo and call
CO. Hagenbeckt, 'Vhe arrangement of the hairs on the fore-
head is the same and the speckling of the fur also, but the
general tint is apparently different in the two; for example,
Trouessart says that the hairs of the head and back are more
distinctly annulated than those of the sides, so that the tint
passes insensibly into fawn-brown (“ fauve-brun”’), then into
clear fawn, then into white under the belly. And according
to Pousargues the hairs of the upper parts are dark brown
(‘‘brun sombre”) and marked on the distal third with two
yellowish-green annuli especially distinct upon the head,
neck, and arms, much less defined upon the cheek, shoulders,
back, sides, and outer face of the legs; the hairs of the chest
and belly are scanty and yellowish red at the extremity, but
the throat and the inner sides of the arms and legs are silvery
grey. The discrepancies between the two descriptions taken
by two authors of repute from the same specimen are difficult
toreconcile. ‘They are also highly instructive as emphasizing
the magnitude of the personal equation to be reckoned with
in judging of species from published diagnoses. ‘The reddish-
yellow (“jaune roussatre *?) hue of the chest and belly must
be very faint, one would imagine, to admit of ‘Trouessart’s
failing to detect it and describing the belly as white, unless
his examination was made by gas- or candle-light. That
Pousargues was probably correct may be inferred from the
circumstance that he saw four specimens in addition to the
the Genus Cercocebus. 283

iii.; Matschie, Saugeth. Deutsch. Ost-Afr. p. 145 (1895) ; Pousar-
gues, Ann. Sci. Nat. (8) iii. pp. 229-235 (1897).
Loc. Brit. E. Africa: Tana River.
This species is known to me only from the figure and
description published by Peters and from the remarks upon
it Matschie and Pousargues have published.
The general colour both above and below seems to resemble
that of C. agilis ; but the arrangement of the hair on the
crown of the head is quite different from that of C. agilis and
C. Hagenbecki. Judging from the figure, which, according
to Matschie, quoted by Pousargues, is correct, the parting is
not, as in those species, a small circular area from which the
hair radiates, but almost Y-shaped; the hairs on the forehead
turn forwards over the brows and are separated by a transverse
parting running from temple to temple from the hairs of the
top of the head, which are long and directed outwards from
a median longitudinal parting, so that their ends overhang,
like a roof, the tops of the ears. The description Pousargues
gives of this arrangement does not express at all clearly, in
my opinion, what the illustration in Peters’s paper shows.
Trouessart’s interpretation is much more in keeping with the
figure. But the two species, C. agilis and galeritus, are, I
should say, much less nearly related than these French
authors believed.

Johnstont, id. loc. cit. pp. 595-596.
Loc. Lake Tanganyika (northern extremity).
The best-marked of these forms appears to be Rothschild,
of which I have seen no specimens.
The remaining examples examined and named _ by
Mr. Lydekker are in the Natural History Museum, as well
as three others received since his paper was written. Two of
these three are from Budzi (8000 feet) in Uganda; the third
is labelled “ Cameroons,” but this locality is, I think, open to
grave suspicion. ‘This specimen is long-coated. The mantle
on the nape and shoulders is brown strongly tinged with
iron-grey. There is also a considerable quantity of grey in
the hair on the fore part of the chest and outer side of the
thigh. Except that there is more grey in the coat, this
example is very like the type of albzgena, which is young.
I believe it represents the adult phase of that species, and
Mr. Lydekker has given it the name albigena. In its grey-
ness it differs from the two examples from Uganda, in which
there is no grey in the brown mantle or on the outer sides of
the legs, which are black. One of these specimens is browner
than the other and both are rather browner than the type of
Johnstoni. Nevertheless I believe the three specimens, which
appear to be adult, are representatives of one and the same
subspecies.
From an examination of all these skins, no two of which
are absolutely alike, I am compelled to believe that two, and
only two, subspecies are involved, namely a western and an
eastern, the former being albigena and the latter Johnstont.
Neumann identified the eastern form from Uganda as
aterrimus ; but for geographical reasons it appears to me
more probable that the type of aterrimus was a young
example of albigena. If so, aterrimus falls as a synonym of
albigena. If, on the other hand, Neumann is right in his
determination, Johnstoni falls as a synonym of aterrimus.
It must be borne in mind that Neumann discovered the
young of the Uganda form to be uniformly black (Zool.
Jahrb. xiii. p. 533, 1900). From this it may be interred
that the young of the Congo form (albzgena) is also black.
The skins I have seen bear ont this interence. Hence, so far
as colour is concerned, the type of aterriémus might be the
young or the brown- or grey-mantled race, It cannot, on
the Genus Cercocebus. 285

form.

Cercocebus congicus, Sclater, P. Z. 8. 1899, pp. 827-828, fig.
The diagnosis runs as follows:—‘‘ Niger, subtts nudi-

This species was based upon a single female specimen
living in the Antwerp Gardens and believed to have come
from the district of Stanley Falls on the Upper Congo.
The reproduced photograph published by Dr. Sclater shows
that the crest on the head was long and rose nearly vertically
from the crown like a column, presenting an appearance
quite unlike that of the crest of C. albigena or C. Hamlyni.

Subfam. Asopryz.
Dorycoris Rutherfordi.
Dorycoris Rutherford, Dist. Ent. Month. Mag. (2) iii. p. 187 (1892).
In ‘ Rhynchota Authiopica,’ t. 1. p. 185 (1905), my friend
M. Schouteden has placed this species as a synonym of the
Pentatoma miniata, Westw., which he figures and enumerates
as a var. of Dorycoris pavoninus, Westw. M. Schouteden
writes :-—“ D. Rutherfordi est forma nitidissima, marginibus
pronoti vix constrictis, a D. miniato tamen, ut videtur, haud
distinguenda.” So far from this being the case, the species I
described as D. Rutherfordi differs from Schouteden’s figure
of D. miniatus (lettered as JD). fuscosus, Germ.) in having
the head wholly metallic green, basal half of scutellum
metallic blue, and a large transverse spot of the same colour
on corium on each side of apex of scutellum, the spot ex-
tending for little more than half across the corium. It may
be correct to regard D. Rutherfordi as a colour-variety of
D. pavoninus, for M. Schouteden has had a large amount of
material through his hands, but it is incorrect to refer it to
the form he has figured.

this contention in a footnote to a paper defending and advo-
eating his classificatory views on the Capside. As _ the
question has a remote Ethiopian interest it may be referred
to here.
In 1878 Costa described a species as Leptopus assuanensis,
which Reuter redescribed as LZ. néloticus in 1881, and Bergroth
once more described as L. strigipes in 1891. ‘Both the two
latter writers in correcting themselves have sought toadd my
Vallerolia Green from Ceylon to the list of synonyms, In
describing Vallerolia I gave the ocelli as only two in number,
and fearing (after perusing the indictments of Bergroth and
Reuter) that 1 might have overlooked a third, I placed the
type of the genus under a microscope, and, with these con-
ditions, sought the opinion of Mr. E. E. Austen, the well-
known dipterist, and of Mr. E. Waterhouse, an experienced
British coleopterist, who were also both satisfied that the
number of the ocelli was two.
It therefore follows that if V. Greent is really the same
species as the synonyms of Leptopus asswanensis created by
Reuter and Bergroth, it is they who have failed to recognize
the proper genus and have placed their synonyms in the
wrong subfamily, for Leptopus is known as possessing three
ocelli, though neither of my critics has alluded to the number
of ocelli inshis svnonymical descriptions.

XL.— On some African Bats and Rodents.
By OLpFIELD ‘THOMAS,
Kerivoula muscilla, sp. n.
Size very small. Ears short, laid forward in the spirit-
specimen they barely reach to the tip of the muzzle; their
breadth equal to their length ; inner margin strongly convex,
outer with a well-marked emargination above, convex below.
Tragus as in Dobson’s second group, a small basal lobule
present, very much as in A. Smith; inner margin evenly
convex, outer slightly concave. Limbs short, less strikingly
delicate than usual; upper surface of forearms and proximal
part of the digits and of hind limbs and feet clothed with fine
golden-brown hairs. Wings to the base of the toes. Poste-
rior edge of interfemoral with a fringe of short curved hairs
growing from its under surface. Prepuce tufted with long
hairs.
Fur long, brownish grey above and below, so far as can be
made out on a spirit-specimen.
Inner upper incisors slender, practically unicuspid, a
rudiment of a secondary cusp present about halfway up the
hinder aspect ; outer incisors long, nearly as long as the inner
ones, each with a minute external basal secondary cusp.
Two small upper and three lower premolars subequal inter se.
Dimensions of the type (measured on the spirit-specimen) :-—
Forearm 27 mm.
Head and body 37; tail 33; head 14; ear 10; tragus on
inner edge 6; third finger, metacarpus 26°5, first phalanx
13°5, second phalanx 15; lower leg and hind foot (c. u.) 17°55
calear 16.
Hab. Ja River, Southern Cameroons.
Type. Adult male. Collected 22nd December, 1905, by
Mr. G. L. Bates. One specimen.
This little Kertvoula is readily distinguishable from any
African species hitherto described by its small size, the
presence of an interfemoral fringe, and its long outer incisors.
Dobson’s K, africana agrees with it in some respects, but is
said to have a tragus as in K. //ardwicket and ears “ longer
than the head” *.
* By this expression Dobson appears always to have meant that the
ears when laid forward extended beyond the tip of the muzzle.

CUieands.) yc... Rete a Pe S. 8. centricola, subsp. n.
I can find no reason to distinguish Du Chaillu’s S. Nord-
hoffi (type B.M. no. 67. 9. 5. 1) from the insular S. Stangeri,
though the form occurring further south in Angola seems
separable. But with regard to Peters’s S. calliurus, it is to
be noted that two specimens from the Como River differ from
the series trom the Benito by the larger size of their ante-
orbital foramina, which may indicate that the more northern
of the two should be separated from the southern; Peters’s
name would then apparently apply to the former.
With regard to the placing of all these six true Sccuré as
geographical forms or subspecies of one species, the links
21s
296 Mr. O. Thomas on
between one and another seem to be so complete that I have
failed to recognize any division of more than subspecific rank.
At first it appeared that at least the dark forms with red feet
(eborivorus) might be separated specifically from the straw-
coloured ones with yellow feet (Stangeri), but the animal I
have named nigeri@ is really practically as yellow as
Stangert, while it has the red feet of eborivorus and the white
neck-patches of Temminckii. Again, an Eastern Congo
specimen has a yellow Stanger? back with red eborivorus feet,
but is without white neck-patches. As to distribution, there
is as yet no evidence that both Stangert and eborivorus forms
occur in any one district, though the ranges of the two types
largely overlap.
The recognition of Wilsond as a Funisciurus and of
Stangert as a true Sciurus is due to Mr. de Winton, who
wrote some notes on the group in 1898 *.
The following are descriptions of the new subspecies :—
Scturus Stangert loande.
Size and general characters quite as in true Stangeri,
though the yellow of the hinder back is rather more vivid.
Head, instead of turning hoary grey on the crown, simply
becoming paler and more whitish yellow than the back; a
dull yollowish patch behind each ear, and the ears themselves
yellow rather than brown. Cheeks whitish or greyish white.
Line edging body-hairs along sides of belly well-marked,
white. Feet, especially the anterior, more strongly suffused
with yellow above. Other characters as in true Stangert.
Dimensions of the type (measured in the flesh) :—
Head and body 285 mm.; tail 380; hind foot 66; ear 21.
Skull: greatest length 68; condylo-basilar length 57;
length of upper tooth-series 11-5.

Coast animal.

on the sides of the neck nearly up to the lower edge of the
ear and in the presence of a distinctly white line along the
edges of the body-fur at the sides of the belly, but distin-
guished by the light speckling of the back being yellowish or,
at most, fulvous instead of strong rufous and by the inner
surface of the forearms being orange-rufous instead of
whitish. Patch behind ear dull orange-rufous. Crown dark
hoary grey. Upper surface of hands blackish, finely ticked
with orange, of feet orange-rufous, becoming rich rufous
terminally,
Dimensions of the type (measured in skin) :—
Head and body 310 mm.; tail (doubtfully perfect) 300 ;
hind foot 64.
Skull: greatest length 68; condylo-basilar length 56-5 ;
length of tooth-row 103.
Hab. Abutschi, Lower Niger.
Type. Adult male. B.M. no. 2.11.10.10. Collected by
Mr. Alexander Braham.
In its yellowish general colour this animal corresponds with
true Stanger’, while resembling members of the eborivorus
group in its neck-patches and reddish feet.
Seiurus Stangeri centricola.
Size, as judged by skull, rather less than in true western
eborivorus. Colours rich and bright throughout, the fulvous
suffusion of the back, often confined in true eborivorus to the
rump and never extending beyond the nape, more rufous in
tone and carried forward on the head to between the eyes.
Line along edge of belly not conspicuous, hoary grey.
Yellowish or rutous of limbs at a maximum everywhere, the
hind feet especially rich rufous.
Skull similar to that of S. ebor’vorus, but rather smaller.
Dimensions of the type (taken on the skin) :—
Head and body (overstretched) 310 mm.; tail 830; hind
foot 61.
Skull: greatest length 66°5 ; condylo-basilar length 955 ;
kngth of tooth-row 11-2.

Jackson in 1905.
Funiscturus palliatus Lastii, subsp. n.
Distinguished from other forms of F. pallatus by having
black lands and feet.
298 Mr. O. Thomas on
Size and general colour as in the darker forms of F. palli-
atus, the dorsal colour closely matching that of /. p. ornatus,
while the belly is a little darker and richer than in any of
them, nearly matching the maroon-red of the tail of F. p. or-
natus. Muzzle, forearms, inner sides of hind limbs, and end
of tail-hairs all of the same rich maroon-red; but the upper
surface of the hands and feet, instead of being also red, are
deep glossy black without trace of red, the change at the
wrists and ankles being apparently abrupt, though there are
microscopic red tips to some of the hairs on the metapodials.
Skull and dentition as usual, except that the top of the
muzzle is flatter, less bowed downwards, and the molars
appear to be rather narrower than in the mainland subspecies.
Dimensions of the type :—
Hind foot, s. u., (c.) 49 mm.
Skull: greatest length 51; length of molar series exclusive
of Oe 8:8.
flab. Zanzibar Island.
Type. Adult male. B.M. no. 6. 6.5. 21. Collected and
presented by J. T. Last, Esq.
This squirrel is so abruptly different from any of the forms
of F, palliatus by its black instead of red hands and feet that
many naturalists would think a binomial should be used for
it; but it is so essentially a member of the palliatus group
that I preter to regard it as a subspecies, especially as faint
indications of red may be found on its feet and also slight
traces of black on those of F. p. suahelicus, its nearest
relative.
In Mr. Oscar Neumann’s account * of the subspecies of
F. palliatus he records F. p. suahelicus from Zanzibar ; but if
his specimens were really obtained in the island he must have
overlooked the very material difference in the coloration of the
feet,
Mus Brockmani, sp. n.
A medium-sized pale grey species, with a very long
pencilled tail.
Size and general proportions very much as in JM. Ver-
reauxt of the Cape. Fur of medium length; the ordinary
hais of the back about 9 mm. in length, the isolated longer
hairs 12mm. General colour above pale buffy grey, paler
than Ridgway’s “ drab-grey,” the light rings to the hairs

African Bats and Rodents. 299
cream-buff. Sides lighter. Belly white, with a sliglit
creamy tinge, the hairs along its sides slaty at base, those on
the throat, chest, and middle area of belly white to the roots.
Kars almost naked, their substance greyish brown. Upper
surface of hands and feet pure white; fifth hind toe without
claw reaching to the end of the basal phalanx of the fourth.
‘Tail very long, finely scaled (15-16 rings to the em.), thinly
haired basally, the hairs lengthening on the terminal half of
the tail to form a distinct pencil, of which the individual
hairs are about 24 mm. long; in colour the tail is sharply
bicolor, brown above and white beneath for its whole length.
Skull, as compared with other African medium-sized
species, characterized by a rather flatter brain-case than
usual, the parietals being less markedly convex; supra-
orbital edges rounded anteriorly, square, not ridged, poste-
riorly. Palatal foramina widely open, their posterior end not
narrowed. Mastoid portion of bulla, as usual in this group,
well defined from the sides of the supraoccipital, with a fair-
sized vacuity at its upper end.
Teeth as in the allied species, the antero-internal cusp
of m? large and well defined, the antero-external minute.
M* with the usual tricuspid interior edge.
Dimensions in the flesh :—
Head and body 108 mm.; tail 161; hind foot 22; ear 18.
Skull: greatest length 29°5; basilar length 23; zygomatic
breadth 14; interorbital breadth 4°2; height of brain-case
from basilar suture 7°6 ; palatilar length 12°6 ; diastema 7°6;
palatal foramina 6°2 x 2:2; length of upper molar series 4°5.
Hab. Upper Sheikh, British Somaliland. Alt. 4500/.
Type. Adult male. B.M. no. 6.3.4.8. Collected 23rd
November, 1905. Presented by Dr. R. E. Drake-Brockman.
This mouse is readily distinguishable from all other
members of the genus by its pale colour above, whiter belly,
and long feathered bicolor tail.
Of other hairy tailed species which may havea relationship
to it, M. Verreauxi and M. albipes have grey bellies, besides
being darker above, while J/. auricomis, which has a white
_belly, has its general body-colour fulvous.
Dr. Drake-Brockman has contributed a considerable
number of interesting Somali animals to the National
Collection, and i have much pleasure in connecting his name
with this very pretty little species.

presented to the British Museum by Mr. W. N. M°Millan, by
whose generosity Mr. Zaphiro was enabled to make this
important exploration.
Ilelogale Macmillani, sp. n.
A very finely speckled form allied to H. undulata and
A tkinsoni.
Size as in the two related species. Fur rather short, the
longest hairs of the back barely attaining 13 mm. in length
and the shorter ones about 8 mm. General colour above
between broccoli-brown and Mars brown, warmer than the
former, greyer than the latter; finely ticked with minute
buffy specks, terminal or subterminal on the dorsal hairs, the
specks far finer than in the allied species and each measuring
less than 1 millimetre in length. Under surface near
Prout’s brown, with scarcely any speckling, a faintly warmer
tinge (Mars brown) on the tips of the hairs. Crown finely
ticked Prout’s brown, becoming Mars brown or verging
towards russet on the sides of the face, lips, chin, ears, and
on areas round and behind the last-named parts. Limbs to
wrists and ankles like the body ; upper surface of hands and
feet russet, without speckling. ‘Tail speckled bistre, a russet
line on the under surface proximally, and a few russet haus
mixed with the pencil at the tip.
Skull and dentition as in the above-named species.
Dimensions of the type (measured in the flesh) :—
Head and body “182” t mm.; tail 159; hind foot 41;
ear 20.
Skull: length of nasals 6; interorbital breadth 9; front of

is peculiar to it. In dentition it corresponds closely with
H, Atkinsoni, and differs equally from the broad-toothed
Ll, hirtula,
Ictonyx capensis show, subsp. n.
Size large, slightly exceeding that of true capensis, there-
fore markedly different from the small erythrea, de Wint., of
Suakin. General marking normal, the black lines clearly
defined, little softened by isolated white hairs or by the tips
of the hairs of the white areas overhanging them. Frontal
spot of medium size, larger than in true capensis, about an
inch long by half an inch broad, running back in a point
towards the crown, separated on each side from the post-
orbital white mark by about half an inch of pure sharply-
defined black. In erythree the median white spot more
nearly approaches the lateral ones. Outer white stripes of
nape markedly broader than the inner. ‘Tail rather less
white than in other subspecies.
Skull apparently rather more elongate in general outline
than in some of the allied forms.
Dimensions of the type (measured in flesh) :—
Head and body 395 mm.; tail 298; hind foot 64; ear 30.
Skull: condylo-basal length 69; basal length 63; greatest
breadth 45; interorbital breadth 18; mastoid breadth 36:3 ;
palatal length 32°3; length of upper p* on outer edge 7-7.
A younger male skull, with nasal sutures still open,
measures 66°5 mm. in condylo-basal length, and a female of
about equal immaturity 62°5.
Hab. Adis Abbaba. Alt. 8500.
Type. Old male. Original number 6. Collected 15th
September, 1904.
«Trapped in a Galla house near the legation.”
This form of Jctonyx differs by its larger size from the
Red-Sea erythree, while by the well-marked black band
separating the frontal from the lateral white face-markings it
is distinguishable from the ¢ntermedia of Uganda and British
Kast Atrica, in which these white areas are scarcely separated
from each other or even form an uninterrupted band across
the face.
Xerus rutilus stephanicus, subsp. n.
General characters as in true rutilus, but the grizzled
302 Mr. O. Thomas on new
yellowish grey—restricted in that form to the centre of the
back—is spread over the whole of the upper surface, so that
the pink area along the sides is reduced to a narrow strip, or
even occasionally absent, the rufous of the forearms and hips
being in such cases isolated from each other. Base of tail
coloured like back. Hands slightly suffused with rufous ;
feet yellowish white.
Dimensions of the type (measured in skin) :—
Head and body 215 mm. ; tail 180; hind foot 53.
Skull: greatest length 53 ; length of upper tooth-series 9:7.
Hab. Between N. end of L. Rudolf and L. Stephanie.
Type from the latter. Alt. 2000’.
Type. Adult male. Original number 132. Collected
18th August, 1905.
These ground-squirrels are by no means easy to sort into
geographical races, owing partly to their variability and
partly to their liability to bleaching, the black parts of the
fur bleaching through rufous and fawn to pale sandy, so as to
give a wholly different appearance to specimens killed before
or after the moult. _ But by a careful comparison of specimens
all in fresh fur I find that the series from the Stephanie area
differ sufficiently on the average from those representing true
rutilus to make a local name advisable, though some examples
show evidence of intergradation. The other named forms in
this group—brachyotus, dabagalla, intensus, and saturatus—
are all further off, both geographically and zoologically, than
the true rutilus of Eastern Abyssinia.
Otomys typus fortior, subsp. n.
By the kindness of Dr. Lampert, of the Stuttgart Museum,
I have been entrusted with the loan of the typical skull of
Heuglin’s Oreomys typus, and I regret to find that it is after
all of the same group as my Otomys Degeni, Heuglin’s descrip-
tion of its incisive grooves proving to be grossly inaccurate,
Their trae number and positions are as described in O. Degeni,
and this latter must, I fear, be regarded as a synonym of
O. typus,
But the Kaffa form obtained by Mr. Zaphiro, though
similar to typus and Degeni in all essential respects, is sutii-
ciently larger to make me think it should have a special
subspecific 1 name. The skull, as a whole, is markedly larger
than that of Degend, which agrees\with what remains of the
specimen of typus. ‘lhe worn surface of the upper molars is
8'5 mm. in length, as compared with 7°7 in the other two.
‘he breadth of the two upper incigors, taken together, is
4-7 mm. in fortior, 4:1 in Degent, and 3-7 7 in typus,
Mammals from North-east Africa. 303
There is no evidence of any marked difference of age
between the three skulls, but, if anything, the type of typus
is the oldest of all.
In colour the type of fortior is rather browner than that of
Degeni, the feet are darker, and the yellowish markings over
the eyes and on and behind the ears are practically absent.
The following are the general measurements of the type:
Head and body 182 mm.; tail 97; hind foot 30; ear 26.
Skull: greatest length 39; basilar length 32:2; greatest
breadth 19°8 ; palatilar length 18°5; palatal foramina 7:7 ;
length of upper molars (crowns) 9°5.
Hab. Charada, Kaffa. Alt. 6000!.
Type. Adult temale. Original number 102. Collected
Ath June, 1905.
Tutera Ilarringtoni, sp. n.
Allied to 7. Emini, Thos., but much smaller.
Size very small for a Zutera. General colour along the
dorsal area clay-colour, darkened by the minute blackish tips
to the hairs. Sides clearer, more nearly “ pinkish buff,” the
hairs with whitish subterminal bands. Lower part of muzzle
pure white, the same region in mini being more or less
buffy. A patch above and behind each eye dull whitish. A
white patch behind each ear. Hands and feet white as
usual, Soles naked posteriorly, but with a band of short
hairs crossing them near the base of the hallux, as in Emdni
alone of other gerbilles. T'ail unusually well tufted, with
long brownish-black hairs, which attain a length at the tip
of about 14 mm.; shorter hairs of tail dull buffy whitish.
Skull closely similar to that of 7. Lmdnz, but conspicuously
smaller throughout.
The posterior palatal vacuities, between the molars, are,
however, much narrower than the anterior palatal foramina,
while in 7. Hmini they are nearly or quite as broad as the
latter.
Dimensions of the type (measured in the flesh) :—
Head and body 96 mm. ; tail 132 ; hind foot 28; ear 19.
Skull: greatest length 30°7; basilar length 22°3; inter.
orbital breadth 6; breadth of brain-case 14:2; diastema 8-2 ;
palatal foramina 5:2 x 2; length of bulla 9 ; length of upper

Type. Adult female. Original number 122. Collected
26th July, 1905.
“ Caught in dry river-bed.”
This pretty gerbille is allied only to 7. Hmint, with which
304 Mr. O. Thomas on new
it shares the peculiar and hitherto unique character of the
hairy band passing across the sole and dividing from each
other the smooth posterior part and the distal part at the base
of the toes, where the tubercles are situated. From that
species, which was discovered at Wadelai by Emin Pasha, it
is at once distinguishable by its much smaller size.
Named in honour of Col. Sir John Harrington, British
Resident in Abyssinia, without whose active assistance
Mr. Zaphiro would hardly have been able to carry out his
successful collecting-trip.
Arvicanthis rea, sp. n.
A very large species without dorsal stripe.
Size larger than in any other species. General colour of
fore-back between hair-brown and smoke-grey, resulting
from a coarse mixture of blackish brown and creamy white ;
posteriorly the light colour becomes more and more buffy, so
that round the base of the tail and on the lower leg it
approaches tawny ochraceous. Sides lined cream-buff.
Under surface and inner side of limbs white. Forearms
dull buffy; hands pale brown; upper side of feet whitish
laterally, pale tawny along the middle line. ‘Tail blackish
above, dull white on sides and below.
Dimensions of the type (measured in the flesh) :—
Head and body 212 mm.; tail 175; hind foot 36; ear 22.
Hab. Charada Forest, Kaffa. Alt. 6090".
Type. Adult male. Original number 101. Collected
30th May, 1905.
This is a remarkably fine species, very different from
anything hitherto described. Its colour has almost a sugges-
tion of silvery blue-grey in it not easy to describe, but very
characteristic, while at the same time its unusual size and the
entire absence of any trace of a darker dorsal band will distin-
guish it from the other members of the group. Unfortunately
the skull is missing, but the species is so distinct as to be
readily recognizable by its external characters.
Lophuromys Zaphiri, sp. n.
General colour above greyish, without the warmer tones
of the other forms, most nearly matching “ hair-brown” of
Ridgway; very finely speckled with buffy. The bases of
the hairs deep rufous. Under surface fawn, more or less
suffused with buffy. Upper surface of hands and feet dull
whitish, ‘ail short, strongly tapering, well haired, markedly
bicolor, black above, whitish below, sharply defined laterally.
Mammals from North-east Africa. 305
Skull with very widely open palatal foramina. Molars
apparently rather broader than usual.
Dimensions of the type (measured in the flesh) :—
Head and body 139 mm.; tail 66; hind foot 20; ear 19.
Skull: greatest length 30; basilar length 25°2; nasals 122;
interorbital breadth 6; length of palatal foramina 6:6 ;
length of upper molar series 5:6.
Hab. District east of the Upper Omo. Type from Bodeli,
Walamo. Alt. 6200’.
Type. Subadult male. Original number 145. Collected
15th September, 1905.
This animal may be distinguished from its allies by its
markedly greyer colour and finer speckling. It has the short
tail of L. jlavopunctatus.
The genus Lophuromys falls readily into two groups of
species—the one from Eastern Africa (Abyssinia to Nyasa),
with speckled fur, and the other Western (Uganda to the
Gold Coast), with unspeckled fur. Whether the forms
within each of the groups will be found to intergrade remains
to be seen, but for the present I have thought it best to use
a binomial term for the Eastern Omo animal.
I have named this species in honour of Mr. Ph. C. Zaphiro,
the collector, who deserves the greatest credit for his remark-
able exploring-trip, of which the series of mammals only

XLII.—Natural History Notes from the RILM.S. Ship
‘Investigator, Capt. T. H. Heming, RN. (retired), com-
manding.—Series III., No. 14. Notes on the Skull of the
Genus Aulastomatomorpha, with Descriptions of some new
Deep-sea Fish. By R. E. Luoyp, M.B., B.Se., Capt.
1.M.S., Surgeon- Naturalist, Marine Survey of India.
THE genus Aulastomatomorpha, first described by Alcock
from a single specimen (Ann. & Mag. Nat. Hist., Oct. 1890),
is unique among the Alepocephalide in possessing a tubular
snout with a small terminal mouth.
A second specimen of the same species was obtained by the
‘Tnvestigator’ in 1904 from 1100 fathoms off the Arakan
coast, and in the following year a new species of this genus
was obtained from 1005 fathoms in the Gulf of Oman.
Material has been thus obtained for a partial description of
the skull of this genus and for a more particular description
of the jaw suspensory apparatus, which can be fully elucidated
without complete disarticulation and destruction of the
specimen.
A notable feature in the structure of this skull is the
forward position of the quadrate and the consequent prolon-
gation of the symplectic and preopercle which articulate
with it.
The quadrate is a thin fan-shaped bone situated almost
entirely in front of the orbit, articulating with the pterygoid
and articular in front, and with the symplectic and the pre-
opercle behind. The large pterygoid is partially overlapped
in front by the small toothless palatine.
The mesopterygoid, also a large bone, forms most of the
lower floor of the orbit; in front it lies to the inner side of
and above the quadrate and pterygoid.
The metapterygoid, a small bone, lies on and partially
hides the symplectic.
The symplectic is of unusual length.
The maxilla, which is very loosely connected with the
snout, consists of two separate crescentic particles, movable
on one another.
Skull of the Genus Aulastomatomorpha., 307
The hyomandibular has the usual articulations,
‘The opercular apparatus consists of the usual four bones.
The preopercle is much prolonged forward to articulate with
the quadrate. The sub- and interopercles are small and
linear. The opercle, a very thin triangular bone, bears at its
upper end a projecting knob, which is seen externally as a
well-marked prominence halfway between the eye and the
upper end of the branchial opening.
The lower jaw contains articular angular and dentary
bones.
The upper part of the snout is formed by one long fibrous
piece of bone intimately united with the vomer in front and
dividing at the base of the snout into two limbs, between
which the fore parts of the frontals fit. This long bone repre-
sents an ethmoid and two lateral ethmoids; a suture separating
these elements could not be found.
In the cranium proper the supraoccipital articulates with
the frontals and lies between the small parietals, separating
them from each other.
The frontals are not fused in the middle line.

Closely resembles A. phosphorops, from which it differs in
the following particulars :—
1. The premaxillary teeth are fewer in number and are
relatively larger ; they are arranged in two sets, an anterior
closely set group of eight or nine, and a posterior group of
three with wide intervals between.
2. The interorbital space is wider than half the diameter of
the eye.
3. The head is covered with a firm smooth skin just as in
A. phosphorops, but in the new species the colour of this
skin is a dark slaty blue. The colour of the rest of the body
is brownish black. ‘The bases of the fins have a blue tinge.
The blue colour is partially preserved in spirit.
4, The total height is only § of the total length excluding
the caudal fin, but as this specimen is smaller and younger
than the type of A. phosphorops, this character does not,
perhaps, constitute a specific difference.

2. There are only seventy-three scales in the lateral line.
3. The anterior of the two nostrils is relatively larger.
The scales of the lateral line are large, measuring as much
as } inch in length.
The total length of the single specimen is 14 inches.
In the middle and hinder parts of the fish, one inch of the
lateral line contains six scales, but in the front these scales
overlap one another to a much further extent, so that one
inch contains eight or nine scales.
In the anterior half of each scale of the lateral line is the
wide opening of its tube; the margin of this opening is
completed in front by a semicircular notch in the hinder edge
of the scale which lies next in front.
Colour almost black ; head and lining of gill jet-black.
One specimen, 14 inches long, from 1005 fathoms in the

It is notable that N. plurisertalis (Gorm.), which this
species resembles in many ways, came from 1010 fathoms in
the Gulf of Panama.
Raia Philipi, sp. n.
The greatest breadth of the disk is equal to the greatest
length, including the ventral fins.
‘The ends of the snout and tail are equidistant from the
cloacal orifice. The snout is slender and prominent. The
interorbital space is 32 in the length of the snout, measured
from an eye or the middle of the mouth.
The anterior borders of the pectoral fins, which are some-
what sinuous, together form an angle of about 85°,
The lateral angles are rounded. ‘he spiracle is large, its
greatest diameter equals that of the eye.
Numerous small spinules occur on the upper surface of the
tip of the snout and close to the antero-lateral margin in its
posterior half only.
The superciliary ridge bears four spines in front and three
behind.
There are five mid-dorsal spines in the branchial region.
Between the ocellus and the margin of the pectoral fin is
a group of lanceolate denticles pointing inwards (probably
characteristic of the male).
The whole lower surface of the snout is covered with fine
denticles.
On the dorsum of the tail are three somewhat irregular
rows of spines. The tail is naked below, the sides of the tail
are spiny.

‘There are two series of larger spines on the pectoral fins,
one series of about twenty opposite the shoulder-girdle (male
characteristic probably) and another of about fifteen opposite
the eye.
There is one large white stellate spine in front of the eye
and two or three smaller ones behind.
There are four or five similar spines in the mid-dorsal line.
On the dorsum of the tail are three regular rows of large

The sides of the tail are spiny.
The lower surface of both disk and tail is smooth and
devoid of spines.
The two dorsal fins are equal in length and are in contact
at their bases; the caudal fin is a minute fold.
The mouth is transverse in its outer part and curved in
the middle; its breadth is exactly half the length of the

There are forty-two rows of teeth across both upper and
lower jaw.
The teeth in the middle of the series are long and curved ;
their bases are heart-shaped.
Colours in the fresh state :—The upper surface of the disk is
pure white, passing into dark grey at the margin of the
pectoral fins. ‘The upper surface of the pelvic fins and
claspers is grey. The iris is black, but the pupil has a white
milky appearance: the anatomical cause of this was unfor-
tunately not made out in the fresh state. The entire lower
surface is purplish black. In consistency the whole body is
soft and flabby ; when taken from the trawl it was rolled up
in a cylindrical posture.
The single specimen (a male), measuring 60 cm. in its
greatest length and 33 cm. in its greatest breadth, was taken
from §20 fathoms in the Arabian Sea off the Baluchistan
coast.
In the same trawl was obtained a black pillow-shaped egg
with four hollow horns at the corners; this measures 24 by
14 inches. ‘lhe horns are not equal in length: those of one
pair are 24 inches long and are separated by a straight border ;
those of the other pair are 14 inch long and are separated by
a tongue-shaped projection of the border, which constitutes a
smaller fifth horn.
The most characteristic features of this species are the soft
flabby consistency in the fresh state and the remarkable
coloration, which suggested the name R. reversa.

XLITT.— The Relations of Paleontology to Biology *
By A. Smira Woopwarp, LL.D., F.R.S.
Tr is clear that the scientific value of a fossil depends upon
the exactness with which the circumstances of its discovery
are determined by a geologist. The briefest experience is
also enough to demonstrate that the well-mineralized remains
of an organism can only be satisfactorily interpreted by an
observer who is familiar with the structure of rocks and their
common constituents. The student of fossils needs as much
elementary training in the geological succession of the rocks
and the varied nature of mineralization as the student of
histology and embryology requires to locate his sections with
exactitude and to understand the action of the different stains
and media he employs. In the one case nature makes the
preparation, in the other case the processes of laboratory
technique are responsible for the difficulties. In both cases
there 1s scope for numerous fantastic conclusions if the
properties of the preservative medium are misunderstood.
Paleontology, however, is essentially a department of
Biology, and it can only be prosecuted with success by a skilled
biologist who has had the elementary geological and mine-
ralogical experience just mentioned. It bears, indeed, the same
relation to the whole world of life that embryology bears to
the structure of an individual organism. ‘The one deals with
the rise and growth of races and their varying relationships,
the other describes and interprets the evolution of an indi-
vidual and the processes by which the different parts of its
mechanism are finally adjusted. Both, unfortunately, depend
on extremely imperfect material ; for fossils are nearly always
mere badly preserved skeletons, and they represent only an
infinitesimal fraction of the life that has passed away, while
enibryos are so much adapted to the peculiar circumstances
of their environment that many of the essential stages in their
growth and development are obscured and modified by
temporary expedients.
The past history of the world of life, as revealed by fossils,
has long been familiar in its general outlines. At least a
century has elapsed since it was made clear that the various
organisms come into existence at different times and in a
definite order, according to their grade in the scale of being,
the lowest first, the highest latest. Several decades have

also passed away since it was recognized that within each
group the lowest or most generalized members appeared
earliest, the highest, most specialized, or most degenerate
towards the end of the race. Modern research is concerned
only with the details of this succession and with the laws
which can now be deduced from the rapidly multiplying
available facts.
Our present knowledge of the geological succession of the
fishes may be briefly summarized to show how Palzontology
contributes to the solution of the fundamental problems of
Biology. The earliest recognizable fish-like organisms, which
occur in Upper Silurian formations, seem to have been mere
grovellers in the mud of shallow seas, nearly all with incom-
pletely formed jaws and no paired fins, devoting most of their
growth-energy to the production of an effective armour by the
fusion of dermal tubercles into plates (Ostracodermi). With
them were a few true fishes which had completed jaws, but
which possessed a pair of lateral fin-folds, variously sub-
divided, instead of the ordinary two pairs of fins (Diplacanth
Acanthodit). The main features of Silurian fish-life were,
therefore, the acquisition of dermal armour, definite jaws, and
the beginning of paired fins. Some of the lowly types thus
equipped survived and further evolved in the Devonian
period ; but the multitude of new-comers which then formed
the majority were much higher in the scale of being (Crosso-
plerygit). They were still adapted for the most part to live
on the bottom of shallow water or in marshes, but they were
typical well-formed fishes in respect to their jaws, branchial
apparatus, and two pairs of fins. Nearly all their bones were
external, very little of their internal skeleton being ossified,
and the only changes they seem to have been undergoing
related to the fusion of some of the head-bones and the more
exact adaptation of their fins and tail to their environment.
Tishes more fitted for sustained swimming were also be-
ginning to appear, and these (Paleoniscide) formed the
large majority in the succeeding Carboniferous and Permian
periods. They were about equivalent in grade to the modern
sturgeons, and the tendency towards change in their structure
was in the direction of effective swimming, by the more
intimate correlation between the fin-rays and their supports
and by the shortening of the upper lobe of the tail. They
still exhibited scarcely any ossification of the internal skeleton.
As soon as the best type of balancing fin and the most
effective type of propelling tail-fin had become universal
among the highest fish-life of the Triassic period the internal
skeleton began to ossify and vertebral centra arose. In fact,
314 Dr. A. 8. Woodward—The Relations of
the whole of the succeeding Jurassic period was spent by the
highest fishes in improving and finishing their internal
skeleton, while their external bony armour began almost
universally to degenerate. Thus, by the early part of the
Cretaceous period the most advanced members of the class
had already become true bony fishes or Téedeosteans. Having
attained that stage of complexity, they admitted of mucli
more variation than formerly, and then arose the immense
host of fishes which characterize the Tertiary period and the
present day. For the first time in fish-history there were
fundamental changes in the head. First, in some genera
the maxilla began to slip behind and above the premaxilla,
so that it was excluded from the gape. Next, in these and
most other fishes, the ear-capsules began to enlarge to such
an extent that the original roof of the brain-case eventually
formed only an insignificant part of the top of the skull. At
the same time the lateral muscles of the trunk extended
forward over the cranial roof, and various crests arose between
them. Finally, it was quite common for the pelvic fins to be
displaced forward beneath the pectoral fins, while the vertebree,
as well as some of the fin-rays, were usually reduced to a
definite and fixed number for each family or genus. Simul-
taneously many of the fin-rays were modified into spines, and
there was a constant tendency for the external bones and
scales to become spinose. At all stages of this progress there
were, of course, stragglers left by the way; and the modern
fish-fauna is therefore a mixture of slightly modified survivors
of many periods in the earth’s history.
To state this brief sammary in more general terms, fossils
prove that the earliest known fish-like organisms strengthened
their external armour so long as they remained compara-
tively sedentary ; that next the most progressive members of
the class began to acquire better powers of locomotion, and
concentrated all their growth-energy on the elaboration of
fins; that, after the perfection of these organs, the internal
bony skeleton was completed at the sacrifice of outer plates,
because rapid movement necessitated a flexible body and
rendered external armour less useful; that, finally, in the
highest types the vertebre and some of the fin-rays were
reduced to a fixed and practically invariable number for each
family or genus, while there was a remarkable development
oi spines. As survivors of most of these stages still exist,
the changes in the soft parts which accompanied the succes-
sive advances in the skeleton can be inferred. Hence Palwon-
tology furnishes a sure basis for a natural classification in
complete accord with the development of the group.
Paleontology to Biology. 315
Now fishes are aquatic animals, and nearly all the fossili-
ferous rocks were deposited in water. ‘The past history of
this chain of life ought therefore to be almost completely
revealed by the geological records. Making due allowance
for the imperfection of collections and the accidental nature
of the discovery of fossils, the general outlines of this history
may indeed be considered as tolerably well ascertained. ‘Thus
the facts of Paleontology not only aid the biologist in
discovering the true relationships of the fishes ; at the same
time they afford a definite means of determining with certainty
some of the fundamental principles of organic evolution
illustrated by them. As identical principles may be deduced
from other departments of Paleontology, most of them are
not likely to be altered in any essential respects by future
discoveries.
It must suffice here to allude only to a few of these general
results which seem to be of far-reaching importance, omitting
details which may be obtained from special treatises. Fore-
most among them is the demonstration that the evolution of
the animal world has not proceeded uniformly, but in a
rhythmic manner. As soon as fishes had acquired the
paddle-shaped paired fins, they suddenly became the special
feature of the Devonian period in all parts of the globe that
have hitherto been geologically examined, and they attained
their maximum development, being more numerous and more
diverse in form than at any subsequent time. None of these
paddle-finned fishes (Crossopterygiz) in the course of their
varied development made much approach towards passing
into the next grade of fish-life with short-based paired fins
and a heterocereal tail (Chondrostec); but among their
earliest representatives there was at least one member of the
higher group, which suggests that the latter arose when the
previous group was just becoming vigorous. At the be-
ginning of the Carboniferous period the higher grade of fish-
life just mentioned suddenly became the dominant feature,
and during the Carboniferous and Permian it attained its
maximum development. ‘l'owards the close of the Permian
period the next higher group was heralded by only one
representative, but as soon as it arose in the ‘l'rias it resembled
its predecessors in becoming immediately dominant, sur-
passing all contemporary races of fishes both in the number
of individuals and in the variety of genera and species. In
the Cretaceous period the highest bony fishes appeared, and
at the end of that period, with the dawn of the Tertiary, they
suddenly diverged into nearly all the subdivisions which
characterize the existing fish-fauna, accomplishing much more
316 Dr. A. 8S. Woodward—The Lelations of
ev: lution in a brief interval than has taken place during the
whole of the succeeding Tertiary time. In short, the funda-
mental advances in the grade of fish-life have always been
sudden and begun with excessive vigour at the end of a long
period of apparent stagnation, while each advance has been
marked by the fixed and definite acquisition of some new
character—an “‘ expression point,” as Cope termed it—which
seems to have rendered possible, or, at least, been an essential
accompaniment of, a fresh outburst of developmental energy.
As we have seen, the successive “ expression points ”’ among
fishes were the acquisition of (1) paddle-like paired fins,
(2) shortened fin-bases but persistent heterocercal tail,
(3) completed balancing fins and homocercal tail, and
(4) completed internal skeleton.
When fossils are examined more closely, it is interesting
to observe that the geological record is most incomplete
exactly at these critical points in the history of each race.
‘There are abundant remains of the families and genera which
are definitely referable to one or other order or suborder ; but
with them there are scarcely any of the links between these
major divisions which might have been expected to occur.
It inust also be confessed that repeated discoveries have now
left faint hope that exact and gradual links will ever be
forthcoming between most of the families and genera. The
“imperfection of the record,’ of course, may still render
some of the negative evidence untrustworthy; but even
approximate links would be much commoner in collections
than they actually are if the doctrine of gradual evolution
were correct. Paleeontology, indeed, is clearly in favour of
the theory of discontinuous mutation, or advance by sudden
changes, which has lately received so much support from the
botanical experiments of H. de Vries.
Further results obtained from the study of fossils have a
bearing even on the deepest problems of Biology, namely,
those connected with the nature of life itself. For instance,
it is allowable to infer, from the statements already made, that
the main factor in the evolution of organisms is some inherent
impulse—the “ bathmic force” of Cope—which acts with
unerring certainty whatever be the conditions of the moment.
So far as human judgment can decide, the varied assemblage
of fishes at each stage of the earth’s history was always in
perfect accord with its environment and displayed very few
signs of waning, even at the time when a new race suddenly
took its place and provided every kind of fish once more on a
higher plane or, so to speak, in a later fashion. The change
was inevitable and according to some fundamental law of
Paleontology to Biology. Ey
life whose influence is independent of temporary equilibrium.
Equally inevitable and irreversible are the essential changes
which may be observed during the evolution of each family
of organisms. As the late Professor Beecher pointed out *,
all animals with skeletons tend to produce a superfluity of
dead matter, which accumulates in the form of spines as
soon as the race to which they belong has passed its prime
and begins to be on the downgrade ; all vertebrates tend to
lose their teeth when they reach the culmination of their life-
history ; nearly all groups of fishes end their career with
eel-shaped representatives; and when a structural character
has been definitely lost in the course of evolution it never
reappears, but, if actually wanted again, is reproduced in a
secondary makeshift. Finally, and perhaps most important
of all, there is in the course of evolution of all groups of
animals to their prime a tendency towards fixity in the
number and regularity (or symmetry) in arrangement of
their multiple parts. The assumption of a fixed number of
vertebrae and fin-rays in the latest and highest families and
genera of bony fishes has already been mentioned. An
irregular cluster of grinding-teeth characterized the Pycnodont
fishes of the Lower Lias, while these teeth began to be
disposed in definite regular rows in some of the Bathonian
forms, and such a symmetrical arrangement henceforth
pervaded the highest members of the family. Many of the
lower vertebrates, both living and extinct, have teeth with
multiplied cusps, and in some genera the number of teeth
seems to be constant ; but in the history of the vertebrates
the tooth-cusps never became fixed individual entities, strictly
homologous in whole races, until the highest or mammalian
grade had been attained. Moreover, it is only in the same
latest phase that the teeth themselves can be treated as
definite units, always the same in number (44), except where
modified by degeneration or special adaptation. The number
of vertebrae in the neck of the lower vertebrates depends on
the extent of this part, whereas in the mammal it is almost
invariably seven whatever the total length may be. Equally
constant in the artiodactyl ungulate mammalia is the number
of nineteen vertebrae between the neck and the sacrum.
In short, the biologist equipped with an adequate know-
ledge of Paleontology cannot fail to perceive that throughout
the evolution of the organic world there has been a periodical
succession of impulses, each introducing not only a higher
grade of life, but also fixing some essential characters that

had been variable in the grade immediately below. He must
also realize that in the interval between these impulses some
minor characters in the families similarly acquired fixity in
their prime, until old age and extinction approached. The
general conclusion is, that if the unknown influence which
Cope has termed “ bathmie force ” were able to act without
a succession of checks from the environment and Natural
Selection, animals would form much more symmetrical
groups than we actually find, and their ultimate grades would
display still more instances of numerical fixity in multiple
parts than can be observed under existing circumstances.
This result almost tempts a paleontologist to risk the
pitfalls of reasoning from analogy and to compare organic
evolution with some purely physical processes. It has already
been pointed out more than once that the initial stages of
animal races resemble the nascent states of chemical elements
in their particular intensity of vigour and unwonted suscepti-
bility to influence ; while Cope himself has hinted that the
‘expression points ” in the evolution of races may, perhaps,
be compared with the phenomena of Jatent heat in the inorganie
world. It now seems reasonable to add that each “ phylum,”
or separate chain of life, bears a striking resemblance to a
crystal of some inorganic substance which has been disturbed
by impurities during its growth, and has thus been fashioned
with unequal faces, or even turned partly into a mere con-
cretion. In the case of a crystal the inherent forces act
solely upon molecules of the crystalline substance itself,
collecting them and striving, even ina disturbing environment,
to arrange them in a fixed geometrical shape. In the case of
an organic phylum, the inherent forces of the colloid germ-
plasm act upon a consecutive series of temporary outgrowths
or excrescences of colloid substance (the successive individual
bodies or “somata”), struggling not for geometrically
arranged boundaries, but towards various other symmetries
and a fixity in number of multiple parts. Palxontology thus
contributes to Biology by placing the oft-repeated comparison
of life with crystallization in an entirely new light.

catalogue of dry bones; though even had it been no more than
this, from the extraordinary character of these bones the book he
has just finished would have been one of exceptional importance :
and this because, for the most part, the remains which he describes
are missing links for which palwontologists and students of phylo-
geny have long been seeking, desiring without hope.
Though Dr. Andrews had not, in many cases, the good fortune
to unearth the first specimens of these remains to be discovered, it
is to him that we owe their determination: to him that the credit
belongs of interpreting the true nature of the puzzles they presented.
But he has himself done much work in the burning deserts of
Egypt, and many of the most important remains described here are
due to the masterly intuition he displayed in the arduous work of
fossil-hunting; many of the biggest prizes were obtained from
ground that others on the same quest had already surveyed and
pronounced barren!
The greater part of this volume is concerned with that most
important group, the Ungulates; and, undoubtedly, the most
striking of these is the bizarre creature which has been named

A single specimen, a gravid female, was found in the
Chirinda Forest, 8.E. Mashonaland, altitude 4500 feet, by
Mr. Guy H. K. Marshall, and presented by him to the
British Museum.
The discovery of a species of the genus Lhampholeon south
of the Zambesi is one of very great interest. The Chirinda
Forest, Mr. Marshall informs me, has a tropical insect-fauna
quite distinct from that of the surrounding districts. Its
reptile and batrachian fauna, when explored, is likely to afford
further startling additions to South-African herpetology.

L.—On the Presence of Two Species of Anabas in the
White Nile and the Bahr-el-Gebel. By G. A. BOULENGER,
F.R.S.
THE large series of specimens collected by Mr. Loat has
established the fact that two perfectly distinct species of
Anabas occur in the White Nile and the Bahr-el-Gebel.
Both were confounded by Dr. Giinther in his original descrip-
tion of Ctenopoma Petherici from Gondokoro. I propose to
retain the name Petheric: for the large specimen figured in
Petherick’s ‘ Travels,’ the others, the supposed young, repre-
senting a smaller species, which I have pleasure in naming
after Dr. J. Murie, who accompanied the Pethericks to
Gondokoro and did most of the collecting.
Anabas Muriet may be defined as closely allied to
A, Petherici, but smaller, not exceeding a length of 80 mm.,
less deep in the body, the depth not exceeding the length of
the head, which is 3 times, or a little less than 3 times, in
the total length, dorsal spines fewer, and coloration different,
the body being covered with numerous black spots, whilst a
blackish ocellar spot edged with yellowish is situated at the
root of, and partly upon, the caudal fin.

LII.— The Primary Septal Plan of the Rugosa.
By R. G. CaRruTHERS *.
[Plate IX.]
THERE has been of late years a revival of the long-dormant
discussion as to the presence of four or six primary septa in
the Rugosa. It would be, perhaps, as well to indicate briefly
the reasons for the investigation of a point which may possibly
seem of subordinate importance.
While most members of the Zoantharia have a hexamerous
or dodecamerous primary plan, certain others, such as
Edwardsia, have an eight-rayed arrangement. By common
consent the latter is regarded as the more primitive type, and
most zooids, whether hexamerous or not, are said to pass
through an Hdwardsia stage; in all cases, so far as it is
known, the fundamental plan, when not of simultaneous
formation, is arrived at by an insertion of bilateral pairs
proceeding in a common order. It is a question whether this
octamerous plan is genetically connected with that of the
Rugosa, an extinct group of Paleozoic corals, commonly
supposed to be primarily tetramerous, but whose other
characters link them with the hexamerous Madreporaria ;
but the very slight amount of actual investigation of the early
stages in these ancient corals has been a bar to their phylo-
genetic classification, and their relations to other Anthozoa
have remained doubtful.

Survey.
Primary Septal Plan of the Rugosa, 357
When Kunth, in 1869 *, first clearly demonstrated the
remarkable pinnate mode of septal development so charac-
teristic of the Rugosa, in which new septa are added at four
distinct points in the circumference of the corallum, he natu-
rally inferred, in the absence of direct evidence, that these
corals had four primary septa. But whenever actual investi-
gation of the point has occurred, not four but six septa have
been found. Thus Pourtales, in 1871, in the youngest
stage he examined in Lophophyllum proliferum found six
septa only, so symmetrically arranged that he regarded them
as primary. It was not till 1902 that the matter was again
taken up. In that year Duerden published an important
paper { in which Pourtales’s conclusions with regard to
L. proliferum were fully supported and in which an inter-
esting relationship of the living Zoanthee to the Rugosa is
suggested ; this paper also contains an excellent survey of
the literature of the subject. In a later paper§ the same
author incidentally figures another instance where he has
found six septa symmetrically arranged in the youngest
stage examined in Streptelasma rectum, and which he regards
as primary ; and while preparing this manuscript for publica-
tion I have seen, through the kindness of Dr. Ashworth, an
advance proof of a further note by Duerden||, in which he
gives a list of five additional species in which six septa,
presumably primary, have been observed.
On the other hand, it may fairly be said that no evidence
has yet been brought forward conclusively demonstrating the
presence of a primary four-rayed condition in these corals,
though quite recently Gordon {], from examination of an
Ordovician Streptelasma, has concluded that in that form
there were four primary septa, and that of the six observed
by Duerden in the Carboniterous Lophophyllum four were the
true primary ones and the remaining two “accelerated
secondary septa’ It is hoped that in the course of the
present paper it will be shown that Gordon’s careful observa-
tions are in no way inconsistent with the presence of a

primary hexamerous plan in the Rugosa, but, on the contrary,
support that view.
There seems to be no doubt that the unsatisfactory state of
our knowledge of these primary stages is due to lack of
sufficiently good material. There is, however, in the calca-
reous shales found in the Carboniferous Limestone Series of
Scotland an abundance of small corals, chiefly Zaphrentids,
and often beautifully preserved. Large numbers of these are
in the collections of the Geological Survey, and in dealing
with them during a revision of the corals for some forth-
coming Sheet Explanations, so many were found to show the
earliest stages of their septal development that opportunity
was taken to investigate the matter further. The majority
were so preserved that on carefully grinding down the tips,
the septal arrangement could easily be seen with the aid of
a hand-lens. This fact to some extent obviated recourse to
microscopic sections, but of the latter about one hundred in
all were made in order to permit of more detailed examination
of the various stages. From the Museum of Practical
Geology in London one or two additional Carboniferous corals
and also several Silurian ones were obtained ; while, owing
to the kindness of Mrs. Gray, I have been able to examine
from her unique collection of the Lower Paleozoic fauna of
Girvan some small specimens of Streptelasma showing these
early stages. ‘They are from the Silurian (Llandovery) rocks
of Woodhall Point and from the Ordovician (Llandeilo) beds
of Craighead.
Sequence of Septa.
In all the corals examined the septa were found to appear
in the same order and manner in both early and late Palo-
zoic forms. As an example, one of the small Carboniferous
Zaphrentids will be chosen for description. The growth of
the first six septa may conveniently be divided into three
stages, but it is to be understood that these stages merge
gradually into one another; it is not till all six septa have
appeared that any pause in the development is met with.
On carefully grinding down the tip of the coral the septal
sequence is seen to be as depicted in Diagram A.
Stage 1—A single septum is seen to stretch across the
calicle from wall to wall (diag. A. 1). This may conveniently
be referred to as the “axial septum.’’ In later stages this
‘axial septum” breaks up to form the main and counter
septa of the mature coral. Microscopie sections show that
the median dark line seen in most septa occurs here also in a
continuous dark band passing down the centre (fig. 1, Pl. [X.).

form the “alar”? primary septa of Kunth (diag. A. 2).

Stage I11.—Shortly after the alar primaries have developed
another pair appears, in the same manner as before, but at
the opposite or “counter” end of the axial septum
(diag. A.3). These also spread outwards, though very
rarely to the same extent as the alar septa. There is now a
distinct pause in the formation of new septa, and no more
appear for some time. Any irregularity that there may have
been previously in the growth of the septa is corrected at this
stage, and the two lateral pairs dispose themselves symme-
trically on each side of the axial line * (diag. A.4). Later
septa are added on a slightly different plan. As before, they
appear at the junction of the last-formed septum with the
wall and in pairs, but instead of moving towards each other
as the two lateral primary pairs did, they all eventually move
towards the counter septum, and all arise on the fossular
faces of the last-formed septa (diag. A. 5,6,&7). No
further description of the development of these later septa
need be given here, as this part of the subject has been fully

and the close of Stage III. on the other, although the section is less than
‘5 mm. thick.
360 Mr. R. G. Carruthers on the
treated by previous observers, among whom Duerden should
be specially mentioned.
The movements above referred to are in part shown by the
varying angles of inclination of the septa to the axial line.
These serve to express the fact that the first six or proto-
septa are developed differently from the later or ‘‘ metasepta.”
The change is marked by the only developmental pause
observed. In other words, the primary septal plan of
these Rugose corals is hexamerous and is arrived
at by an insertion of bilateral pairs analogous to that
occurring in the soft parts of the rest of the Madreporaria
and, indeed, in most Anthozoa.
There is commonly some irregularity in the growth of the
two lateral protoseptal pairs, and in some cases an indication
of a spiral, or, at any rate, an alternating arrangement. The
direction of the spiral, however, was found to vary in diffe-
rent specimens of the same species, and may quite well be
an irregularity of no special significance, such as commonly
occurs in living corals. The important point is that this
irregularity, when it occurs, is never so strongly marked as
to interfere with the sequence above given—~. e., the axial
septum appears first, followed by the alar primary pair, and
this by the counter lateral pair. Further consideration of
this point may therefore be left to future investigation.
The septal sequence given above was originally observed
in some varieties of Zaphrentis Phillipst, Ed. & H., and has
since been found in several other species enumerated below,
together with the various stages found in each :—

Primary Septal Plan of the Rugosa. 361
The lower Paleozoic corals in the above list all had to be
sectioned for the microscope before the early septa were
visible. Consequently fewer specimens were examined than
in the Carboniferous corals, of which nearly two hundred were
obtained, showing Stages I. to III. But enough were
olituined to show that these early Palaeozoic forms agreed
exactly in their initial stages with the Carboniferous ones, a
conclusion of interest in view of Gordon’s suggestion that
there were four primary septa in the early Rugosa. But,
using the length of the septa as a guide to their age, an
examination of Gordon’s own figure* of an Ordovician
Streptelasma shows that it is in perfect accordance, from
Stage I. onwards, with the septal sequence above described ;
the tendency to a spiral growth of the primaries is perhaps
slightly more marked than usual, though this may well be
an accident of preservation.
Except for Dibunophyllum and Cyclophyllum, all the
corals examined were small forms. This is, of course, simply
due to the fact that in large, heavy forms the delicate tip is
more easily destroyed by rolling or movement of any kind.
In no instance have I found any essential divergence in
the arrangement of the primary septa in the genera examiued ;
and from the uniformity displayed in this respect, even in
corals far removed in point of time, it seems reasonable to
suppose that the sequence will be found to extend to the
Rugosa as a whole, and that Duerden and Pourtales were
right in considering these corals to be primarily hexamerous.
Similar instances of the formation of the early septa in
bilateral pairs have been observed in certain Mesozoic Hexa-
corallids t, but, indeed, the great majority of the Zoantharia
seem to have a primary hexamerous plan, attained in most
eases by the insertion of bilateral pairs. It is in the later
stages that, as Duerden remarks, “ divergences are introduced
which are to be regarded as of the most fundamental im-
ortance in coral and actinian morphology.”
While these results bring the Rugosa into closer associa-
tion with modern corals and dismiss the idea that they are
primarily tetramerous, and as such built on a more primitive
basis than other Madreporaria, yet there are reasons to
suppose that septal formation in these ancient corals took place

in a more primitive way than that now existing; these
considerations, however, I must defer to a future occasion.
The last point I wish to deal with concerns the orientation
adopted for the figures in this paper. While in living corals
the first six or twelve septa appear simultaneously, the ento-
celes in which they are formed arise in bilateral pairs, of
which the first lateral pair appears on the dorsal surface.
Similarly the dorso-lateral pair of exoceles arises before the
ventro-lateral one. And again, the first six tentacles of most
corals arise over the septa, and the dorso-lateral pair appears
first. It would seem to be a general rule in the Zoantharia,
indeed, that in the insertion of bilateral pairs of this nature
the first appears on the dorsal surface. ‘lhe natural conclu-
sion is that in the Rugosa the first lateral pair of septa to
appear, @. é. the alar septa (2.2), arose on the dorsal side of
the corallum, and this whether the septa were exclusively
entocelic or not.
It is only fair to Duerden to remark that the reverse
orientation seen in his figures was adopted before the order
was known in which the six primary septa of the Rugosa
appeared.
Before concluding this paper I must express my hearty
thanks to Dr. Ashworth, of the University of Edinburgh, for
much valuable help, especially for the loan of papers not
otherwise obtainable, and to Dr. Flett and Mr. T. C. Hall, of

LIV.— Note on the Type Specimen of the Bat Micronycteris
microtis, Miller. By Marcus W. Lyon, Jun.
Micronyereris urcrorrs was described by Mr. Gerrit S.
Miller, Jun.*, in 1898 from a single specimen, which is still
the only one known, in the collection of the United States
National Museum. Dr. Knud Andersen f has recently raise 1
the question as to whether the ears of the type are damaged.
The following history of the type, part of which was probably
not known to Mr. Miller, and remarks on the ears may prove
of interest.
The specimen, an adult male, now a skin and skull, U.S.
National Museum number *, was collected at Greytown,
Nicaragua, by Dr. L. F. H. Birt; date of collecting not
known. It was entered in the National Museum Catalogue
on February 2, 1589, as an alcoholic, and the skull was
catalogued on April 16, 1889. There is no record showing
at what time the alcoholic was made into a skin. The wing-
membranes are considerably torn and some hair has slipped
trom the lower back and abdomen, but otherwise the skin is
in good condition. he skull is perfect. The colour-value
of the skin is much lessened by the fact that it was immersed
for an unknown time in alcohol or other preserving fluid.
The basal portions of the hairs of Mdicronycteris megalot’s are
pure white. ‘They were probably so in MM. microtis, but the
preserving fluid has apparently darkened them to a dirty
white. ‘The ears of the type of J/. microtis measure, from
meatus to apex, 12 mm., and the greatest breadth is 8 mm.
The corresponding measurements in the skin of an adult
male, U.S. National Museum Catalogue number 102913,
from La Guaira, Venezuela, are 20 mm. and 12 mm. respec-

tively. 1 have examined the ears of the single specimen of
M. microtis very carefully, and can find no evidences of
singeing or other apparent injury that might have caused
them to shrink from 20 mm. to 12 mm. In places about
3 mm, of the ear has been rolled or folded on itself, giving
the margin of the ear a heavier appearance than in that of
M. megalotis. The outer surface of the ear of JM. microtis is
furred about one-half the distance from the base to the tip,
and in M. megalotis the furring extends about one-third that
distance. I can detect no essential differences between the
skulls of the two species. The forearm of JZ. microtis, as
already noted by Miller and Andersen, is considerably shorter
than that of the Mexican form of MM. megalotis and a little
smaller than in Venezuelan examples of the typical race.
The same is true of the tibia and foot.
[I am glad that my note on Micronycteris microtis, Miller,
in the July number of the ‘Annals’? has induced Dr. Lyon
to give the above interesting details on the type specimen.
But I nust admit that I still do not feel satisfied that the
extraordinarily small ears of this example are in their natural
condition. Iam all the more inclined to doubt on this point
as (in addition to the case referred to in my paper, p. 50,
footnote) | have recently seen another very striking instance
of shrinkage of the ears in a bat: in a series of Pipistrellus
pipistrellus from Ireland, kindly shown me a few months ago
by Major Barrett Hamilton, the ear-conches of a// examples,
without exception, had shrunk to little more than half their
natural size; the specimens were preserved in alcohol and in
other respects undamaged. With their small ears they looked
very strange indeed, and I cannot help thinking that if this
series of bats had not been the well-known P. pipistrellus,
but, say, a Micronycteris ; if they had not come from Ireland,
but, say, from Central America, from which material for
comparison is considerably scarcer; they might easily have
been described as a readily distinguishable new species, and
—in view both of the very great difference in the size of the
ears of these specimens as compared with individuals in a
normal state of preservation, and of the fact that in this case
Lot a single specimen only was available, but a series of
individuals all exhibiting the same peculiarity—the mistake
would have been very excusable. One statement in Miller’s
description of M/. microtis—contirmed by Lyon—seems to me
worth emphasizing, viz. that the skull does not differ appre-
ciably from that of M, megalotis ; it is, of course, not decisive
evidence that microtés is not specifically distinct from mega-
Sir G. F, Hampson on new Pyralide. 373
fotis, but—taken together with the fact that also externally,
apart from the size of the ears, there is no difference worth
mentioning between microtis and megalotis (for even the
colour of the single skin of miécrot’s, on which Miller laid
some stress in his description, is, according to Lyon, un-
reliable) —it certainly looks rather suspicious.
My argument is, briefly summed up, this:—As in two
British Museum specimens of Micronycteris hirsuta
(98. 10. 9. 12-14), preserved in alcohol, the ears, for some
reason or other, have shrunk far below their natural size
(my paper, 2. s. c.); as in a series of Lrish Prpistrellus
pipistrellus, preserved in alcohol, recently shown to me,
the ears, for some reason or other, have shrunk to little more
than half their natural size; so, the only specimen known of
Micronycteris microtis, which differs from I. megalotis in no
essential external character but its curiously small ears, and
the skull and dentition of which are indistinguishable from
those of M. megalotis, may, very likely, be an example of
this latter species with much shrunk ears. Whether my
assumption is right or wrong cannot, I believe, be definitely
proved, until further material is forthcoming from the type
locality of MM. microtis. If it is wrong, the case will stand as
follows: the genus MJicronycterts, as restricted by me,
numbers four species; three of these (JZ. meyalotis, minuta,
hirsuta) have the ears proportionately quite of the same size,
but differ in many important cranial, dental, and external
characters; the fourth species (M. microtis) has extra-
ordinarily small ears, but ds otherwise practically indistin-
guishable, cranially, dentally, and externally, from M. mega-
lotis! Allis possible, but strange as the characters of this
latter “species” look to me, I still think it safer, for the
present, to leave the question as to its validity open to
doubt.—Knup ANDERSEN. |

426 On a new Species of Lyconus.
some particulars in a direction contrary to the usual change
of developmental proportion.
A further distinction lies in the much longer pectoral fins
of L. pinnatus; while both specimens are too large to be
affected by the great development of the pectorals, which is
not uncommon in larval Teleosteans, the present imperfect
state of the type of L. pinnatus makes it impossible for us to
make an exact comparison of the two species in this respect,
though we have no reason to doubt the accuracy of Giinther’s
figure.
The relatively much larger eye of L. pinnatus may be a
youthful character only, and the present state of the type of
that species makes any comparison of its scale and fin-ray
formule with those of 1. brachycolus impossible.
L. pinnatus has only one canine-like tooth on each side of
the vomer; this may be a distinction of importance, because,
so far as we know, vomerine teeth tend rather to decrease
than to increase in number with age. It has certainly some
of the anterior dorsal rays considerably prolonged. In
LL. brachycolus the first four rays are broken, and, though the
first ray is slightly stouter than the rest, none of them seem
to be stout enough to afford foundation for any considerable
production. Moreover, prolongation of the anterior dorsal
rays may be a feature of merely sexual importance (cf. Onus
cimbrius).
The following key should suffice to distinguish the two

LXIUI.—Natural History Notes from the RILM.S. Ship
‘Investigator, Capt. T. H, Heming, R.N., commanding.—
Series III., No. 15. Second Preliminary Report on the
Deep-sea Aleyonaria collected in the Indian Ocean. By
Prof. J. ArrHuR THomson, M.A., and W. D. HENDERSON,
M.A., B.Sc., Carnegie Research Fellow, University of
Aberdeen.
In the Ann. & Mag. Nat. Hist. vol. xv. 1905, pp. 547-557,
we published a preliminary report on a collection of deep-sea
Aleyonarians from the Indian Ocean, entrusted to us for
examination by the Trustees of the Indian Museum through
Prof. A. Aleock, LL.D., F.R.S. As we have completed our
survey, we wish, pending the publication of the memoir, to
sum up the general results and to make a few corrections in
our first preliminary report.
The collection includes 86 species, of which 61 seem to be
new. Descriptions of the new forms are given in the
memoir about to be published. The distribution of the new
forms is as follows :—6 Stolonifera, 8 Alcyonacea, 3 Pseud-
axonia, 22 Axifera, and 22 Stelechotokea. It has been
found necessary to establish tive new genera— Stereacanthia
and Agaricoides (the latter established by Mr. J. J. Simpson,
Zool. Anzeig. xxix. 1905, pp. 263-271, 19 figs.), both in the
family Nephthyide, subfamily Siphonogorgine ; Acantho-
muricea and Calicogorgia in the family Muriceide; and
Thesioides in the family Kophobelemnonide. We submit
brief notes on these five new types.
New Types.
The genus Stereacanthia, from the Andamans, is a Siphono-
gorgid in the vicinity of Lemnalia. A bare, densely spicu-
lose trunk, made up of large longitudinal canals, with thin
spiculose walls, bears a branched polyparium with the polyps
disposed singly or in small crowded bundles; the aboral
bands of spicules on the infolded tentacles form a simple
pseudo-operculum ; the spicules are warty spindles or golf-
club forms, and there are no quadriradiate double-stars as in
Lemnalia.
The genus Agaricotdes, from 6° 31’ N., 79° 33’ 45” E., is
a remarkable Siphonogorgid, perhaps distinctly related to
Lemnalia (Gray, emend. Bourne), but quite unlike any other
type known to us. It is unbranched, mushroom-like, with
complex octagonal verruce, pedicelled anthocodiz, intro-
428 Prof. J. A. Thomson and Mr. W. D. Henderson on
versible zooids, a tentacular operculum, echinate spindles
and hockey-club forms, and many peculiarities of structure,
The genus Acanthomuricea, represented by A. ramosa
from 7° 55’ N., 81° 47’ E., 506 fathoms, and A. spicata from
6° 31’ N., 79° 38/ 45” E., 401 fathoms, is a Muriceid, perhaps
related to Placogorgia (Wright & Studer). ‘The two species
are upright colonies, irregularly branched in one plane, with
thin bark-like coenenchyma of rough imbricating scales, with
prominent verrucze on all sides, with conical tentacular
opercula, and with very heterogeneous spiculation.
The genus Calicogorgia, represented by C. investigatoris
from 11° 14’ 30” N., 74° 57/ 15” E., 68-148 fathoms, and
C. rubrotincta from the Bay of Bengal, 88 fathoms, is a
Muriceid, probably related to Verrill’s somewhat vaguely
defined Anthogorgia. ‘the colonies are irregularly branched
in one plane, the verruce are prominent with spicules in
eight bands, with a conical operculum consisting of a crown
and points, with warty spindles straight or curved.
The genus Thestoides, from 18° 0’ 15” N., 93° 30/ 45” E.,
448 fathoms, and 16° 25’ N., 93° 43’ 30” E., 463 fathoms,
is a Kophobelemnonid, near Bathyptilum, with a greatly
elongated slender rachis borne by a short stalk without
pinnules, with long slender autozooids without calyces and
without any spicules.

It is very difficult to decide what is the best course to
pursue in dealing with genera like Sympodium and Umbellula.
It is not easy to give distinctive diagnoses of the new species
we have felt compelled to establish, and yet the tout ensemble
of the characters of each results in a quite characteristic
appearance. References to Sympodium sp., Sympodium sp. (?),
Sympodium sp. a, and the like are tedious and confusing. It
is probable that the investigation of a large number of repre-
sentatives (which this collection did not include) will show that
the differences between sume of our species are variational or
modificational. ‘The same remarks apply, though not so
obviously, to Acanthogorgia, Acamptogorgia, Muricella, Acis,
and Pennatula,
Viviparity.
In 1900 Prof. 8. J. Hickson reported his discovery of
embryos in sit@ in Gorgonia capensis—the first case of
Viviparity that he had observed in his wide and prolonged
study of Alcyonarians.
432 On Deep-sea Alcyonaria from the Indian Ocean.
He pointed out, however, that viviparity had been pre-
viously reported in Corallium rubrum by Lacaze-Duthiers,
in “ Clavulaires pétricoles”? and in Sympodium ( Alcyonium)
coralloides by Marion & Kowalevsky, in three species of
Nephthya (found at depths of 269-761 fathoms) by Koren &
Danielssen.
In Prof. W. A. Herdman’s collection from Ceylon we
found embryos én st?@ in Gorgonia capensis as Hickson had
stated. Corroborating Marion & Kowalevsky, we found
embryos in Clavularia pregnans (Th. & H.) and C. parvula
(Th. & H.) collected by Mr. Cyril Crossland from Zanzibar
and Cape Verde Islands respectively.
In the present collection we found embryos—blastule,
gastrule, and slightly more advanced stages—in eight
species :—Sarcophytum aberrans, sp.n., Chrysogorgia flexilis,
W. &8., Ceratotsis gracilis, sp. n., Paramuricea indica,
sp. n., Distichoptilum gracile, Verrill, Umbellula elongata,
sp. n., Funiculina gracilis, sp. n., and Pennatula indica,
sp. n.; meanwhile Mr. James J. Simpson, M.A., B.Sc., has
also found embryos in specimens of Js¢s Aippuris included in
the littoral collection from the Indian Ocean (see Journ.
Linn. Soc., Zool. xxix. p. 431, 1906).
We have also found embryos in a species of Sclerophytum
from the Red Sea and in the British Primnoa reseda.
It is therefore clear that viviparity is by no means un- ~
common in Alcyonarians, and it will be interesting to discover
if it is particularly characteristic of deep-sea species.
Some particular Facts of interest in the Collection.
One specimen of Sarcophytum aberrans, sp. n., is supported
by a siliceous axis like a thick knitting-needle, 300 mm. in
length by 2°3 mm. in breadth, probably the spicule of
Monorhaphis or some allied sponge.
Analogous on a smaller scale is the siliceous sponge-
spicule which forms the support of Sympodium incrustans,
Sp.sls
The spicules of Chironephthya macrospiculata, sp.n., some-
times attain the unusual length of 8°3 mm., and some of
those of Spongodes uliginosa, sp. n., are almost equally huge
(S mm.).
Noteworthy is the great heterogeneity of the spicules in
some of the forms, e. g. plates, disks, triangles, rods, spindles,
and ‘* golf-clubs ” in Acanthomuricea spicata, sp. Nn.
Besides the very peculiar habit—incrusting a huge siliceous
rod—there are many interesting features in Sarcophytum

aberrans, Sp. Me, @ J. the occurrence of several sizes of auto-
Zooids, the ae of almost the whole of a large tentacle
into the stomodeum, and the presence of ova and embryos in
the siphonozooid canals.
The dimorphism which Gray recorded in his Paragorgia
nodosa is confirmed in P. splendens, sp. n. ;
The complex differentiation of the polyps in Agaricoides
Aleocki, Simpson, is quite unique. The presence of numerous
Foraminifera in the stomodaum is also interesting.
Among other peculiarities we may mention the very
remarkable tentacles of Thestotdes inermis, gen. et sp. n., the
remarkable base of Anthoptilum dec/piens, sp. n., the small
number of rays (3) in the pinnules of Pteroéides triradiata.
In regard to a collection which is a very feast of colour, we
may call special attention to the exquisite colour-schemes of
Pennatula veneris, P. pendula, P. splendens, and P, indica.
Some of the epizoic animals are interesting, e. g. the
peculiar Solenogaster (Lhepalomenta gorgonophila?) on
Acamptogorgia circium, sp. Nn.
LXIV.—On the Land Molluscan Subgenus Celorus, Pilsbry.
_ By G. K. Guns, F.Z:S.
ReceNTLY Messrs. Sowerby and Fulton submitted to me for
examination some shells they had received from Mr. Y.
Hirase, of Kyoto. They were labelled Hulota (Colorus)
caviconus, and at first I was inclined to regard them as an
undescribed form, as upon comparison with that species they
presented several striking differences, having a more elevated
and convex spire, a smaller diameter, a more contracted
umbilicus, and a more laterally contracted aperture. Upon
receiving further material, however, several intermediate
forms were found, and the species, therefore, presents a con-
siderable amount of variation.
The subgenus Ce/orus, which, so far as our present
knowledge enables us to judge, appears to be restricted to
Japan, was established for the reception of the then only
known species—Lulota cavicollis—by Prot. Pilsbry (Proc.
Acad. Nat. Se. Philad. 1899, p. 528). The group has not yet
been investigated anatomically ; it will, in all probability,
prove to be most nearly allied to Plectotropis, to which group,
in fact, the first species was originally assigned by the writer.
The presence in the two species, subsequently discovered, of
434 On the Subgenus Ceelorus, Pilsbry.
the cuticular processes, so characteristic of Plectotropis, goes
to confirm this view.
Two of the species not having hitherto been figured, I take
this opportunity of giving illustrations of them, while, to
facilitate a survey of the group, I have added figures of the
type species.

whorls are spirally sculptured, neither of which features is
mentioned in the diagnosis by Prof, Pilsbry. Probably
the type is not mature; all the mature specimens I have seen
possess the tubercle; on the other hand, one shell, which
appears not quite mature, shows but a slight indication of a
swelling. ‘The extreme form mentioned above from Goto

Similar to V. Gouldii, Gray, but snout shorter, its length
less than the distance between the anterior border of the orbit
and the anterior border of the ear, scales on upper surface of
snout, vertex, and occiput much larger than those on the
- supraocular and temporal regions, and caudal scales much
larger. The latter are almost tubercular, and form very
well-marked whorls, 7 whorls, in the middle of the tail, corre-
sponding to the length of the snout; the scales on the upper
surface of the tail form a double tubercular crest. Pale

By OLDFIELD ‘THOMAS.
I.—A new Name for Sciurus Roberti, Thos.
In 1903 * I gave to an Eastern Brazilian squirrel the above
name in honour of its discoverer Mr. Alphonse Robert. But
two years before t Mr. Bonhote had already used the same
term for a squirrel obtained by Mr. Robert Swinhoe in
Formosa, and I would therefore propose for the Brazilian
species the name of Scturus Alphonse.
Il.—On the Allocation of certain Species hitherto referred
respectively to Oryzomys, Thomasomys, and Rhipidomys.
In connexion with Mr. W. H. Osgood’s work on the genus
Peromyscus, my attention has been drawn by him to the
characters that distinguish the group containing ‘‘ Hesperomys
(Rhipidomys) cinereus, Thos.,”’ which was made the type of
a special genus “Thomasomys” by Dr. Elliott Cones in 1884 f.
But with the exception of one more recent description of
my own, the name has hitherto been practically ignored. It
is used, however, in Trouessart’s Catalogue on the authority
of that one description.
Now, however, a revision of a number of the species
concerned shows that Thomasomys (the cacophony of whose
name J. deplore) is a well-defined group, containing a con-
siderable number of species, and that it may be distinguished
from Oryzomys by certain characters of the palate, well shown
in some admirable figures published by Mr, Outram Bangs
in 1900§, and by the possession, in most of the species, of
only 1—2=6 mamme, as compared with the invariable
2—2=8 of Oryzomys.
In Oryzomys (including the subgenus Oligorycomys, Bangs)
the palate extends some distance behind the posterior border
of the last molar, the palatal notch is narrowed or pointed,
and on each side of it, between m* and the corner of the
mesopterygoid fossa ||, there is a small pit or pair of pits,

§ Proc. New England Zool. Club, i. p. 94, pl. i. (1900).
|| A good deal of confusion has arisen as to the use of the words meso-
and interpterygoid for the fossee situated (@) between the pterygoids in
the middle line and (2) those placed laterally between the ecto- and
entopterygoids of either side, the former being median and unpaired, the
South-American Rodents. 443
often deeply excavated and always readily perceptible. This
style of palate is shown in Mr. Bangs’s figures 1 } and 26 of
the plate quoted.
In Thomasomys, on the other hand, with which I must
synonymize Lrioryzomys, Bangs, the mesopterygoid fossa
extends further forward (to between the last molars), is, as a
rule, rather more squarely open in front than in Oryzomys,
and there are no lateral pits. Mr. Bangs’s figure 3b shows
excellently this type of palate.
To the genus as thus defined the following species,
mostly described under Oryzomys, prove to be referable,
though, of course, the number of namme is not as yet known
in all of them :—
Thomasomys princeps, Thos.
pretor, Thos.
aureus, ‘Tomes.
—— pyrrhonotus, Thos.
vestitus, Thos.
— cinereus, Thos. (Type of genus.)
— Kalinowshit, Thos.
—— incanus, Thos.
—— paramorum, Thos.
— Tuczanowskii, Vhos.
— leops, Thos.
niveipes, Thos.
laniger, Thos.
monochromos, Bangs. (Type of Erzoryzomys,
Bangs.)
Serrugineus, Thos,
—~ dorsalis, Hensel.
sublineatus, Thos,
It will be noticed that nearly all these species are inhabitants
of the mountainous regions of N.W. South America, from
Colombia to Peru, none of them penetrating into Central
latter lateral and paired. To avoid this confusion I would suggest that
while the former, the median one, might still be called the mesopterygoid
fossa, the new name of parapterygoid might be given to the lateral “ones,
the names themselves then explaining the positions that the fosse
respectively bear to the skull as a whole.
Mr. Miller, in figuring a Microtine skull (N. Am. Faun. no. 12, p. 27,
1896), has followed the usage of the human anatomists in calling the
lateral fossee simply “ pterygoid,” and then using interpterygoid for the
median one; but other authors have used this latter name for the lateral
ones, and as the names do not explain themselves, their misuse is always
probable. It would therefore seem advisable to drop them altogether
and to use terms which are self-explanatory.
444 Mr. O. Thomas on
America. But three of them—sublineatus, ferrugineus, and
dorsalis—extend into Eastern Brazil, the first-named in the
north, the other twoin thesouth. 1’. ferrugineus and dorsalis
are also exceptional in possessing 2—2=8 mamme.
No doubt other described species will be found to be refer-
able to Tomasomys, but the above are all that I have as yet
been able to identify.
But, further, a study of the same mammary and _ palatal
characters in the series of forms that have been allocated to
Rhipidomys brings out the fact that among these there are
two distinct groups differing from each other exactly as do
Oryzomys and Thomasomys; for up to the present no accurate
definition of “ thipidomys”’ has been given, and the fact that
the tail of any species is more or less tufted and that the
animal had certain other external peculiarities have been
taken as sufficient reason for its reference to what I now
find to be the composite genus Rhipidomys.
The true Rhipidomys has 1—2=6 mamma, a long heavily
tufted tail, broad climbing feet, and the palatal characters of
Thomasomys, from which it is to be distinguished by its
external peculiarities and by the presence of well-marked
divergent supraorbital ridges, these being practically absent
in Thomasomys.
The species to which the following specific names have
been given appear to belong to this genus :—leucoductylus,
Tschudi (type of genus) ; mastacalis, Lund; macrurus,
Gerv. ; latiémanus, Tomes; ochrogaster and Coues?, Allen ;
Sclateri, Goodfellowt, venezuele, venustus, microtis, pictor,
nitela, and fulviventer, ‘Vhos.; and Macconnelli, de Winton ;
but the last-named is somewhat aberrant in other characters
than those above mentioned, and may hereafter prove to be
separable from the rest.
The species belonging to the second group have absolutely
the skull of Oryzomys, and they also, so far as is kuown,
have 2—2=8 mamme. It is clear, therefore, that they
should be altogcther removed from LRhipidomys, and either
assigned to Oryzomys or form a special group of their own.
On the whole it appears to me they may best be regarded
as a subgenus of Oryzomys, as follows :—
CEcomys *, subgen. nov.
Number of mamme (2—2=8) and essential skull-characters
as in Oryzomys, though there is a tendency for the brain-case
* oixos, a house. Quite a number of specimens, of different species,
are noted as haying been caught in native houses.
South- American Rodents. 445
to be proportionally larger, more rounded, and Rhipidomys-
like. Feet broad, suited for climbing; fifth hind toe propor-
tionally long. Tail with the body-fur encroaching on its
base for half an inch or more; terminal part well haired—
more so than in true Oryzomys—and generally pencilled,
though never so heavily as in Rhipidomys.
Type. Rhipidomys benevolens, ‘Vhos.
The following is the list of species belonging to this
group :—
Oryzomys (Ccomys) bicolor, Tomes.
( ) dryas, Thos. (probably =bicolor).
—_ ( ) benevolens, Thos. (Type.)
—— (——) marmosurus, Thos.
) mamore, Thos. (infra).
— (——-) pheotis, Thos.
) paricola, ‘Vhos.
) rosilla, Thos.
(——) Roberti, Thos.
Rhipidomys rufescens, Thos., also probably belongs to
Gcomys, but the essential parts of the type skull have unfor-
tunately been broken away.
In the transference of these species to Oryzomys only one
name—dryas—clashes with a term already in use in that
genus. But it so happens that this animal is probably the
same as ‘l’omes’s bicolor, which, as the type now shows, was
described from a discoloured specimen with a broken tail,
while my distinction of dryas was based on the difference of
colour and the longer tail as compared with T’omes’s descrip-
tion, the type not being then available for examination.
With regard to Nyctomys, hitherto somewhat doubtfully
separated from Rhipidomys, I am able to point out an
important character which will distinguish it from that genus.
This is that the first upper molar, instead of being evenly
oblong, with six subequal cusps, has only five well-developed,
the antero-internal one being almost or quite obsolete. The
group may therefore possibly be an offshoot of the Pero-
myscus stock, with no close relationship to Rhipidomys at all.

IIIl.—A new CEcomys and Two new Species of Holochilus.
Oryzomys (Ccomys) mamore, sp. n.
One of the largest species of the group, as large as a
medium-sized Rhipidomys, about the same size as VU. (@.)
marmosurus. Hairs of back about 10 mm. in length,
Ann. & Mag. N. Hist. Ser. 7. Vol. xviii. 33
446. Mr. O. Thomas on
General colour of the type evidently somewhat altered by
spirit, but apparently of the usual fulvouvs colour, with pure
sharply defined white* belly. Hands and feet dull buffy
whitish. Basal half-inch of tail furry like the body, the
remainder well haired to the tip, but scarcely pencilled; pale
brown throughout. Mamme 2—2=8.
Skull very like that of a medium-sized Rhipidomys in
general appearance, but the palate absolutely of the Oryzomys
type. Interorbital region narrow, its edges sharply defined,
with delicate ridges evenly diverging backwards; very
different to the strong overhanging ledges of O. (@.) mar-
mosurus. Palatine foramina large and open, extending back
just to the level of the front of m’. Mesopterygoid fossa
broad, parallel-sided, its anterior edge evenly rounded.
Dimensions of the type (measured on the spirit-specimen ):—
Head and body 130 mm. ; tail 161; hind foot 27; ear 20.
Skull: greatest length 33°5; basilar length 25°6; greatest
breadth 17°5 ; interorbital breadth 5:2; palatilar length 14:1;
diastema 8°6; palatal foramina 5:7; length of upper molar
series 5°3.

The species of Gcomys, being distinguished from each
other almost entirely by size and skull-characters, with a
remarkable uniformity of coloration, I have no doubt (in spite
of the discoloration of the type) about the distinction of this
animal, which may be separated from its only equal in size,
O. (Gi.) marmosurus, by its narrower interorbital region, less
developed orbital ledges, and larger palatal foramina.
Flolochilus chacarius, sp. n.
Allied to 77. vulpinus, but with more slender feet and
teeth.
General colour as in H/. vulpinus. Back near “ raw-
umber”; sides buffy, brightening to ochraceous buff along
their lower edge; belly “ buff,’ the hairs white basally ;
throat, chest, and inguinal region entirely white. Ears
mixed buffy and brown. Upper surface of hands pale
brownish buffy, of feet glossy greyish white. The feet them-
selves smaller and narrower than in other species. ‘Tail
shorter than head and body, brown above, greyish white
belew.
* Yellow in the specimen, but this has certainly been affected by the
spirit.
South-American Rodents. 447
Skull lightly built. Back of nasals and front part of
frontals markedly concave upwards along the middle line.
Supraorbital edges sharp, not’ heavily ridged. Palatal
foramina well open. Molars decidedly narrower than in
other species. Last upper molar rather simpler than in other
Species, its anterior lamina directly transverse, scarcely
thickened internally, not connected with the second lamina.
Dimensions of the type (measured in flesh) :—
Head and body 175 mm.; tail 164; hind foot 38; ear 17.
Skull: greatest length 36°7; basilar length 30; greatest
breadth 19°5 ; nasals 14; interorbital breadth 4°5; palatilar
length 18; diastema 10°6; palatal foramina 7°5 x 2°5; upper

This species is distinguishable from /7Z. vulpinus of the
lower Parana and La Plata, which it resembles in colour, by
its delicate feet and narrow molars. When further examples,
of different ages, of both forms are available for examination,
I also think it probable that a real difference in the structure
of m* will be definable.
Flolochilus balnearum, sp. n.
A small species, with short tail and large teeth.
Fur long and fine, the hairs of the back 14-15 mm. in
length. General colour of the usual type, the back rather
ereyer than in H. chacarvus, the sides rather duller buff and
the belly a deeper buff, so that there is less difference between
the sides and belly, the hairs of the last-named part broadly
slaty at base ; pectoral and inguinal light patches more
strongly contrasted white. Feet comparatively short ; soles
naked, granulated, with more strongly marked pads than in
the allied species. ‘Tail comparatively short, blackish above,
dull greyish below.
Skull short and thickly built. Interorbital region but
slighily concave mesially. Palatal foramina broad, but not
widely open, owing to their rounded margins and the breadth
of the septum, so that the actual slits are unusually narrow.
Molars unusually broad and heavy, their length scarcely more
than in /. chacarius, but their breadth considerably greater.
Anterior lamina of m* thickened internally and connected with
the next lamina by an enamel band. In their position also

the molars differ by facing further outwards than usual, the
line of the two grinding-surfaces, if produced internally,
meeting at an angle almost approaching a right angle,
i.e. about 110°. In H. chacarius they meet at about 130°,
and in a large example of H. vulpinus atover 150°. I cannot
find that there is any appreciable age-variation in this
character, though its exact definition is not easy.
Dimensions of the type (measured in the flesh) :—
Head and body “ 132” mm.*; tail 133; hind foot 35°5;
ear 18.
Skull: greatest length 35; basilar length 29°5; greatest
breadth 20; nasals 13°3; interorbital breadth 4°33 palatilar

LXIX.—A new Species of Pteridium (Scopol’) from the
North-east Atlantic. By L. W. Byrne.
ONLY a single species of Pteridium (Scopoli), as defined by
Giinthert (‘Challenger’ Deep-sea Fishes, p. 105), has
hitherto been described—P. atrum (Risso), a denizen of the
Mediterranean coast of France, where, however, it appears
to be uncommon.
On a recent cruise in the northern portion of the Bay of
Biscay the 8.8. ‘ Huxley,’ employed by the Marine Biological
Association of the United Kingdom upon the International
Fishery Investigations, took a fish of this genus which
appears to be reterable to a previously undescribed species,
which I propose to name in honour of my friend Dr, E. J.
Allen, the Director of the Association.
Pteridium Allent.
Form stout ; body compressed in caudal region, its greatest
height about 4 times in its length (without caudal fin).
* This would appear to be an under-measurement; the skin looks
contracted, but the aa and body still measure over 140 mm.
+ The “some slightly enlarged teeth along the inner series of the
mandible and on the vomer,’ mentioned by Giinther, are stated by
Moreau, on the authority of Bellotti, to be found in the male only.
Pteridium from the North-east Atlantic. 449
Head depressed, 34 times in length (without caudal), nearly
twice as long as broad, its breadth about equal to its height
at isthmus, Snout rounded, with numerous mucous glands,
about 44 times in head. IZye of moderate size, longer than
the flat interorbital space is wide, 6 times in head and less
than 1} times in snout. Gape 22 times in head, barely
reaching beyond the level of the hind margin of orbit;
maxilla weak and but little expanded distally. Villiform
teeth in both jaws and in a V-shaped band on vomer.
Marginal fins continuous, their bases covered with skin
and scales; fin-rays difficult to count, probably D. ca. 90,
A. ca. 55. Ventrals each with two closely apposed rays.
Pteridium Alleni, X 1.
Body covered with a copious mucous secretion ; scales very
small, approximately 105 in a longitudinal and 35 in a
transverse series. Lateral line very indistinct and broken.
Colour, after preservation, umber-brown, darker on top
of head and front part of dorsum, paler on belly. Rays of
marginal fins dark.
Length of type 101 mm. (96 mm. without caudal).
Hab. Mouth of English Channel, near La Chapelle Bank,
ca. 450 fath.
The chief dimensions of the type are as follows :—Length
96 mm. ; length, including caudal fin, 101 mm.; length to
origin of dorsal fin 83 mm., to origin of anal fin 49 mm.;
greatest height of body 23 mm. ; length of head 27-5 mm.,
of snout 6°5 mm., of eye 4:5 mm. ; interorbital width 4 mm. ;
height of head at isthmus 15 mm.; breadth of head 15 mm. ;
length of upper jaw 10°5 mm.
While the general form and proportions of the body are
somewhat stouter in P. Ad/ent than in P. atrum, neither they
nor the fin-ray and scale formule afford a ready means of
identifying the species. In P. Alleni, however, the head is
slightly larger and markedly more depressed than in P. atrum,
450 Mr. C. T. Regan on Fishes from
the eye is larger, and the interorbital space far narrower; in
contradistinction to the comparatively short gape and weak
maxilla in P. Allenit, P. atrum has a gape extending far
beyond the hind margin of the eye and a stout maxilla with
a broad distal end.
These points are shown by the following percentages, taken
from three specimens 80-90 mm. long (without caudal) of
P. atrum and the type of P. Allent:—

1, Breadth of head not more than half its length or
< of its height at isthmus. Interorbital width
about equal to snout and more than 13 times as

more than 3 the length of head; insertion of ventrals below
the middle of pectoral. Brownish, with several dark vertical
bars and an indistinct broken lateral stripe or series of spots.
‘'wo specimens, 50 mm, in total length.
The connected dorsal fins and the low position of the
pectorals suggested that this little fish might prove to be the
type of a family distinct from the Atherinidee, but dissection
of one side of one of the specimens shows that the vertebral
column and pectoral arch are as in typical Atherinide; the
pelvic bones are quite remote from the clavicles, to which
they are connected by a ligament.

This genus, hitherto unrepresented in the British Museum

addition to the species described below, the genus includes
the Paradules obscurus of Klunzinger.
Nanoperca, Gthr., 1861, is very closely allied to Edelia,
but the preorbital has only two rather strong serre and the
interorbital region is naked. Microperca (non Putnam),

LXXI.—Description of a Second new Species of Mangabey
(Cercocebus Jamrachi). By R.I. Pocock, F.L.S., F.Z.S.,
Superintendent of the Zoological Society’s Gardens.
[Plate XI. ]
THE young male monkey upon which this new species is
based was deposited in the Zoological Gardens by Mr. Roth-
schild, who has placed its determination and description in
my hands. I propose to name it after Mr. Albert E. Jamrach,
the well-known importer of wild animals, who procured the
specimen.
Cercocebus Jamrachi, sp. n. (Pl. XI.)
The face, ears, palms of the hands, and soles of the feet
flesh-coloured, the face much more pallid than the hands and
feet, which are of a decided rosy pink ; one or two small asym-
metrically disposed pigment-spots on the face and ears. The
iris of the eyes olive-brown ; the white of the eye with a
faint grey-blue tinge. The hair everywhere a uniform dirty
white. On the posterior portion of the crown of the head
the hair is thick and long, forming an occipito-parietal tuft
as in C. Hamlyni *; it is also long behind the ears, but on
the cheeks it is quite short and sparse, whereas on the brow
there is a scanty and shaggy fringe of long, semierect, and
partially porrect hairs.
Length from the crown of the head to the root of the tail
12 English inches (=300 mm.) ; length of the tail 19 inches
(=475 mm.).
Loc. Molinga (? Mlungu), Lake Mweru.
The great interest attaching to this monkey lies in its
remarkable coloration, which is unique in the genus Cerco-
cebus. ‘That the specimen is not a true and complete albino
is shown by the normal tint of the eyes. It may be an
albinescent variety of some species of Cercocebus, but of this
there is as yet no proof. In the paper containing the description
of C. Llamlyni I have discussed the possibility of the types of
that species and of C. congicus being partially albino sports
of C. albigena Rothschildi or an allied species. ‘The reasons
therein given for dismissing the hypothesis of albinism apply
also to the present case, except for the total absence in this
species of pattern showing symmetrical arrangement. More-
over, C. Jamrachi differs from the three forms just named
* Ann. & Mag. Nat. Hist. (7) xviii. pp. 208-210, pl, vii. (1906).

and resembles the typical form of Cercocebus albigena in
possessing a brow-fringe and in the shortness of the hair on
the cheeks. Hence it cannot be regarded, on the evidence,
as a further stage in the albinescence, if albinescence it be,
traceable from C. albigena Rothschildi to C. congicus and
thence to C. Hamlynt. In fact, C. Jamrachi stands by
itself. It may be at once distinguished from C. albigena
albigena, its nearest ally, by its uniformly whitish coloration.
A further point to be noted in connexion with this species
is its occurrence in a locality lying about 10° 8. latitude in
tropical Africa. It is, therefore, the southernmost represen-
tative of the genus Cercocebus known up to the present time.

On a new Chameleon from Mount Ruwenzori. 473
LXXIII.—On a new Chameleon from Mount Ruwenzoré.
By G. A. BouLENGER, F.R.S.
A SINGLE specimen of a sinall female chameleon, which I
then referred provisionally to Chameleon biteniatus, Fischer,
was presented by Sir Harry Johnston to the British Museum
in 1901. Further specimens which have since come into my
hands induce me to regard this chameleon as the type of a
new species, for which I would propose the name of
Chameleon rudis.
Differing from Ch. biteniatus in the coarser scaling and in
the much longer scales forming the gular and ventral crest,
the longest of these, on the throat, measuring half the diameter
of the orbit. Uniform blackish olive.
From snout to vent 52 mm,; tail 47.
I hope later to give a detailed description and figure of
this chameleon, which has been briefly alluded to by Mr. J. L.
Monk, ‘ Zoologist,’ 1903, p. 824, as likely to prove a new
species,
MISCELLANEOUS.
A common British Starfish.
To the Editors of the * Annals and Magazine of Natural History,’
GuyrtemEen,—Prof. Clark, of Cambridge, U.S.A., has kindly called
my attention to a blunder in the synonymy of Solaster papposus on
page 89 of my ‘ Catalogue of British Echinoderms’; as it refers to a
common species, perhaps you will allow me to correct it. The
specific term papposa was first used for a starfish by Linnzeus in
the 2th edition of the ‘Systema Nature,’ page 1098, so that its
date is 1767. I have no palliation to offer for the blunder.

A Correction.
Paramilionia rubroplagata, B.-B., ante, p. 345.
I wish to withdraw this name, inasmuch as it falls under Sangala
gloriosa. Some little time ago I bought from a soldier who had
just returned from one of the West-African expeditions a few
insects, nearly all Lycenide, but among them were two specimens
of this moth. I referred carefully to several of the most important
Old-World collections and could not name them. Hence I
A474 Miscellaneous.
described them as new, and it was only when I showed the specimens
to my friend Mr. Herbert Druce, and he recognized them at once as
a well-known South-American insect, that I discovered my error.
The soldier has never been to America in his life, and I conclude
some friend must have given them to him, but unfortunately the
supposition that they came from Sierra Leone put me off the scent
altogether. The simplest plan will be to withdraw the name and
treat the description as non est, G. T. Beraune-Baker.
Trichoniscus pygmeus, G'. O. Sars, a Woodlouse new to the British
Fauna. By Ricwarp S. Baenatt, F.ES.
Early this month I discovered a tiny woodlouse that seemed to
find its home in soft and worm-riddled earth, and which upon
examination proved to be Trichoniscus pygmeus, G. O. Sars, a
species that, so far as I am aware, has not been taken since Prof.
Sars described it from Christiania in 1897. As I hope to describe
and figure this and other interesting Isopoda in a future part of the
‘Transactions of the Natural History Society of Northumberland,
Durham, and Newcastle-upon-Tyne,’ the briefest account will
herein be sufficient.
Trichoniscus pygmeus, G. O. Sars.
Trichoniscus pygmeus, G. O. Sars, Crustacea of Norway, ii. p. 162,
pl. Ixxii. fig. 2.
Easily recognized from other species of Trichoniscus by its small
size and by its comparatively broad antenne, which have the
flagellum only triarticulate. The dorsal face is roughened by
numerous tubercles arranged in transyerse rows, whilst the lateral
parts of thoracic segments are edged with small spicules. Length
2mm. and about one third the length in breadth. 7. pygmaeus
bears a strong resemblance to T'richoniscoides albidus, Budde-Lund,
but apart from the smaller size may easily be separated by the three
visual elements of each eye, the eyes of T'richoniscoides being simple.
T. pygmeus is, moreover, easily recognized from other species of
its genus by its slow, rhythmic, and almost worm-like movements,
and here again it strangely resembles 7’. albidus, the habits of both
species, in fact, being practically identical.
Taken in numbers in gardens at Winlaton (Co. Durham), October,
and several from garden of Hancock Museum, Neweastle-on-Tyne,
November 1906.
Prof. G. 8. Brady, F.R.S., and the Rev. Canon Norman, F.R.S.,
have most kindly confirmed my identification of this species, and
through Dr. Norman’s generosity I have had the additional satis-
faction of examining co-types of both species mentioned in this short
and hastily prepared note, from Prof. Sars, Norway.
