5o 6 PO GAG o otaon bone The sylvan powers
Obey our summons; from their deepest dells
The Dryads come, and throw their garlands wild
And odorous branches at our feet; the Nymphs
That press with nimble step the mountain-thyme
And purple heath-flower come not empty-handed,
But scatter round ten thousand forms minute
Of velvet moss or lichen, torn from rock
Or rifted oak or cavern deep: the Naiads too
Quit their loved native stream, from whose smooth face
They crop the lily, and each sedge and rush
That drinks the rippling tide: the frozen poles,
Where peril waits the bold adventurer’s tread,
The burning sands of Borneo and Cayenne,
All, all to us unlock their secret stores
And pay their cheerful tribute.

Crustacea (Oxyrhyncha) in the Collection of the British
Museum. By Epwarp J. Miers, F.L.S., F.Z.8., Assis-
tant in the Zoological Department.
[Plates IV. & V.]
THE present paper contains descriptions of all the species of
Oxyrhyncha in the British-Museum collection that appear to
have been hitherto unrecorded, with the exception of a few
specimens whose age or condition is such as to render it un-
advisable to describe them as new to science. ‘'T'wo or three
were noticed, but not described, by White, so long ago as 1847,
in the ‘ List of Crustacea in the Collection of the British
Museum.’
For diagnoses of the new genera briefly referred to below,
and characters of the families, I must refer to my paper on
“The Classification of the Maioid Crustacea,’”’ published in
the ‘ Journal of the Linnean Society, Zoology,’ vol. xiv. p. 634,
for the present year.

Acheopsis Giinthert, sp. n.
Carapace broadly triangulate, moderately convex.
trum short, spines acute.
(Ple FV cig. 1h.)
Ros-
There is a small supraocular spine.
The spines of the carapace are disposed as follows :—There is
a very large perpendicular spine upon the gastric region, a
large blunt conical tubercle upon the cardiac, and a smaller
tubercle upon each of the branchial regions. The postocular
spine is small. Behind the eyes, on the subhepatic region, is
a blunt tubercular prominence. The anterior legs (in the
female) are small. The ambulatory legs are smooth, of
moderate length; the terminal joints in the first pair long,
slender, and nearly straight; in the following pairs slightly
curved. Length to base of rostrum 4 inch.
Hab, Cape of Good Hope (H.M.8. ‘ Herald’).
A single adult female is in the collection. Length of cara-
pace about 4 inch.
This species is easily distinguished by the remarkably pro-
. minent gastric spine. The terminal joints of the legs and the
carapace in front of the gastric spine are slightly hairy. In
Species of Maioid Crustacea. 3
Acheopsis spinulosus, Stm., also from the Cape of Good
Hope, of which specimens of both sexes are in the collection,
and which is the only other known species of the genus, there
are three spinules on the gastric region and several upon the
sides of the carapace. The genus Achwopsis appears to repre-
sent Inachus in the southern hemisphere.
I dedicate this species, which is certainly one of the most
striking of those here to be described, to Dr. Giinther, F.R.S.,
Keeper of the Zoological Department, by whose continual
kindness and encouragement my studies have been so greatly
facilitated.
Eucinetops? Stimpsoni, sp. n.
Carapace subpyriform and convex, upper surface without
spines or tubercles. Rostrum deflexed ; the spines of which
it is composed small, flattened, acute, and separated by a
narrow fissure. Immediately behind the eyes are two small
blunt prominences ; and a third, at a little distance, represents
the postocular spine. There are two very small tubercles at
the distal end of the slender basal antennal joint. The second
and third joints are not, as in LH. Lucasii, very broad, but
cylindrical. Anterior legs (in the female) very slender and
smooth. Both the body and legs are pubescent. Length of
carapace 2 inch.
Hab. N.K. coast of Australia (Cuming).
This species is represented only by a single female spe-
cimen.
I am in some doubt as to whether this species should not
be made the type of a genus distinct from Hucinetops. It
resembles the Californian £. Lucast’, Stimpson, in the small
and deflexed rostrum, the great length and mobility of the
eyes, the very small epistome, &c., but differs in the more
elongate-triangular carapace, and in the non-dilatation of the
second and third joints of the flagellum of the antenne. If
distinct as a genus, I should propose to designate it as Ana-
cinetops. It comes very near to Camposcia, but is dis-
tinguished by the presence of a distinct rostrum and by the
longer, slenderer eye-peduncles.
Halimus truncatipes, sp. n.
Carapace elongate-ovate, moderately convex; gastric region
with about eleven tubercles, of which four anterior are ar-
ranged in a transverse series, and three posterior in a median
longitudinal series, the others are lateral ; cardiac region with
two obtuse tubercles, and, posterior to these, three in a longi-
tudinal median series; the last of these, on the posterior
margin of the carapace, is an acute spine. ‘There are three
1*
4 Mr. E. J. Miers on new or little-known
or four obscure tubercles on each branchial region, and six
spines on each lateral margin, including the two spines which
represent the upper orbital margin. ‘The spines of the ros-
trum are acute and strongly divergent. There is a spine at
the extero-distal angle of the basal antennal joint. The
merus joint of the outer maxillipedes is strongly produced at
its antero-external and the ischium joint at its antero-internal
angle. The anterior legs (in the male) are small ; arm with
a spine at the distal end of its upper margin ; wrist obliquely
carinated; palm slender, smooth, and compressed ; fingers
straight and acute. The penultimate joints of all the ambu-
latory legs are dilated and almost square-truncated at their
distal ends, and the terminal joints strongly curved and acute.
Postabdominal segments (in the male) with a slight convexity
in the middle line. Length of female nearly 14 inch.
Hab. Australia (Bowerbank).
The legs are clothed with long fulvous hairs.
This species is distinguished from /H. arzes and specimens
I refer to H. spinosus by the much more squarely truncated
joints of the ambulatory legs, from H. auritus by the exis-
tence of a spine on the posterior margin of the carapace, and
from H. tumidus by the prominent lateral marginal spines,
&c. In Hess’s description of H. spinosus the form of the
penultimate joints of the ambulatory legs is not stated. If
the specimens now described as HZ. truncatipes belong to that
species, it will be necessary to give a distinct designation. to
those in the Museum collection (from Victoria and King
George’s Sound, West Australia) which are now referred to
HT. spinosus.
Of Z. truncatipes, besides a fine female example from
Australia, there is a male, without definite locality, in the
British-Museum collection.
Trigonothir obtustrostris, gen. et sp. nov.
(Pl. IV. fig. 2.)
The carapace is triangular, narrowing anteriorly, and
smooth ; cardiac region convex. There is a large and pro-
minent rounded tubercle on the cardiac region; and the an-
tero-lateral margins, which are straight and otherwise un-
armed, terminate posteriorly in similar prominent lobes; on
the posterior margin of the carapace are two small tubercles.
The very prominent rostrum is rounded above and in front,
and perfectly flat on its under surface; the lateral carine are
acute and on a level with the flat under surface. The basal
antennal joint is unarmed; and the slender flagellum is con-
cealed beneath the rostrum. The anterior legs (in the male)

are rather small, palm compressed, and fingers excavate at tips.
The ambulatory legs are smooth, decrease regularly in length,
and their terminal joints are slightly arcuate and acute.
The male postabdomen is apparently six-jointed (though
now broken at the tip), the penultimate and antepenultimate
joints coalescent. Length nearly ? inch.
Hab. Unknown.
A single male is in the collection.
The AMuenia pyramidata of Heller, from the Red Sea,
should perhaps be referred to the genus Trigonothir, but
differs from 7. obtustrostris in the absence of the lateral
rostral carine, &c.
The genus 7rigonothir is characterized principally by the
form of the prominent obtusely rounded rostrum, which is
armed, in 7’. obtustrostris, with lateral carine. It is further
distinguished from Menethius by its immobile eyes and the
want of a preocular spine; from Huwenia by the latter charac-
ter; and from Simocarcinus by the form of the anterior legs.
Huenia pacifica, sp.un. (Pl. IV. fig. 3.)
Carapace elongate-triangular, smooth, with three small
tubercles on the gastric region, which is somewhat elevated,
and a more prominent tubercle on the cardiac region. The
antero-lateral margins, which are nearly straight, terminate
posteriorly in a small tubercle or spine. The rostrum is very
long, slender, compressed, and straight; the preocular spine
is very small. The basal antennal joint is angulated, and
has a very small tubercle at its extero-distal angle. Post-
abdomen of male 7-jointed, smooth ; the edge of the sternal
plastrum is reflexed, and forms a raised rim around the margin
of the terminal postabdominal segment. Length of carapace
54 lines, rostrum 4 lines.
Hab. Fiji Islands, Ngau (HLILS. ‘ Herald’).
The description is taken from a male example, in which,
unfortunately, all the legs are wanting.
In a female specimen in the collection from Ovalau in the
Fyji group, which may very probably belong to the same
species, the rostrum is much shorter, the lateral expansions of
the carapace are unequal and separated by a semicircular
emargination, the anterior are larger and rounded, the poste-
rior truncated at the end. The ambulatory legs are very
slender and not at all dilated, with a small tubercle at the
distal end of the merus joints. The fourth to sixth postabdo-
minal segments coalescent.
This species differs from the H. proteus, De Haan, and /7.

heraldica, White, in the much longer, slenderer rostrum of the
male, which is not vertically deep as in those species.
H. Grandidieri, A. M.-Edwards, from Zanzibar, is founded
on a female example, which differs from the female from the
Fijis in the Museum collection in the truncated anterior
lateral and subacute posterior lateral lobes of the carapace. H.
depressa, A. M.-Edwards, also founded on a female example,
seems to belong to the following genus (Simocarcinus).
SIMOCARCINUS, Miers.
I propose to establish a new generic division under the
above name for the species Simocarcinus simplex, typified by
the Huenia simplex, Dana, from the Sandwich Islands, which
differs from the typical Huende in having a more robust body,
much shorter rostrum, no preocular spine, the lateral lobes of
the carapace in the female much smaller, the anterior legs in
the male with the palms turgid, not compressed, and ambu-
latory legs cylindrical, not compressed or dilated. _
The two species described by Dana (H. simplex and H.
brevirostrata) are, beyond a doubt, the male and female of one
and the same form. Specimens from the Sandwich Islands
are in the collection of the British Museum, of both sexes.
The females in the Museum collection differ slightly from that
figured by Dana in having the anterior lateral lobes of the
carapace larger and subtruncated ; but this is perhaps due to
the age of the specimens.
CYCLONYX, gen. nov.
This new generic division is established for the remarkable
species described by White as Huenia frontalis (P. Z. 8. 1847,
p- 223; and Zool. Samarang, Crust. p. 21, pl. iv. f. 3, 1848).
The single specimen in the British Museum is apparently
the exuvia of a female, and resembles the females of Huenia
in the laterally expanded carapace ; but in Oyclonyx frontalis
the lateral expansions are continuous, not divided into ante-
rior and posterior lobes. The rostrum is flattened and of a
transversely oval form, and completely conceals the flagellum
of the antennee, whose basal joint is scarcely distinguishable
from the surrounding parts of the body. The eyes are set in
the narrow emargination between the margins of the carapace
and rostrum. ‘The epistome is short. ‘The outer maxillipedes
have the merus joint small and not much produced at its
antero-external angle. The anterior legs are now wanting.
The ambulatory legs (of which only the second and third are
now perfect) are angulated, cristate above, the penultimate

joints truncated at their distal ends, against which the ter-
minal joints are retractile. In the postabdomen the sutures
of all the joints are clearly distinguishable.
Hab. 2
Perhaps, when the examination of specimens in good con-
dition shall have determined the structure of the orbits and
antenne of this remarkable form, it will be found necessary
to remove it to the Periceride. or the present I retain it in
the neighbourhood of Huenia, to which it is allied in many
respects. The form of the rostrum alone suffices to distin-
guish it from all its allies.
Maiide.
Chorilibinia gractlipes, sp.n. (Pl. IV. fig. 4.)
Carapace subpyriform, smooth, and spinose above, the spines
disposed as follows :—four in the middle line, of which two
are on the gastric, one longer on the cardiac, and one strong
curved spine upon the posterior margin. There are two strong
spines upon the branchial regions above; and below them,
immediately above the bases of the ambulatory legs, are four
small blunt spines. The posterior margin of the carapace is
produced and forms a thin edge. Below, upon the pterygo-
stomian region, is a rather strong spine; and there is a blunt
spine at the antero-lateral angles of the buccal cavity. The
rostrum is prominent, the spines coalescent at base and diver-
gent in their distal half. The upper orbital margin is promi-
nent and divided by a narrow fissure; and there is a wider
fissure below. The anterior legs are small, slender, smooth,
palm slightly compressed, and fingers straight and acute. The
ambulatory legs are long and very slender, and are clothed
with distant tufts of small curled hairs. The first ambulatory
legs in particular are very greatly elongated, and with the
terminal joints very long and slender. The postabdominal
segments (in the male) are all distinct. Length of carapace
to base of rostrum, in the larger specimen, nearly 3 inch.
Hab. Papua (H.MS. ‘ Herald;’ the locality may be
doubtful).
Two male individuals are in the collection of this very
interesting species. I assign it to the genus Chorilibinia of
Lockington without much hesitation, although the generic
diagnosis and specific description of his species (C. angusta)
from California leaves much to be desired in point of com-
pleteness. The structure of the rostrum and orbits is the same ;
and the basal antennal joint bears a long spine on its outer
margin. The inferior surface of the body is densely pubes-
8 Mr. E. J. Miers on new or little-known
cent. OC. angusta is distinguished by the existence of three
spines on the antero-lateral margins &c.
Paramithrax (Leptomithrax) compresstpes, sp. n.
Carapace subpyriform, moderately convex, and covered
with numerous small, wart-like, rounded tubercles, but without
spines, except that on the gastric and cardiac region there is a
small conical spine. On the antero-lateral margins, behind
the strong spines of the upper margin of the orbit, is a series
of six small spines. The spines of the rostrum are short,
slender, and but slightly divergent. The basal antennal joint
is not much enlarged, and has two granulated spines at
its distal end, and one on its inner margin. There is a
blunt granulated tubercle on the anterior margin of the epi-
stome, below the antennulary fosse. The merus joint of the
outer maxillipedes is broad and rounded at its antero-external
and produced and subacute at its antero-internal angle. The
anterior legs (in the female) are small, slender, and perfectly
smooth, without spines or tubercles. The ambulatory legs
are smooth and very robust, with the antepenultimate and
penultimate joints longitudinally sulcated ; the antepenultimate
joints in all except the last pair are flattened and greatly
dilated distally ; the terminal joints are straight and smooth ;
postabdomen wanting. Length of carapace to base of rostrum
2 inches.
Hab. Canton (Hon. E.-India Co.).
This species is represented by a single female specimen.
In the form and tuberculation of the carapace it resembles P.
barbicornis, Latr., but differs from that species and all others
of the genus in the smoothness of the anterior legs and the
remarkable dilatation of the antepenultimate joints of the am-
bulatory legs. It is probable that the carapace and legs were
densely pubescent in the living animal. It would also appear
to be allied to P. wrsus, Herbst, which, according to Gerst-
ecker’s description, has the “tibia”’ anteriorly triangularly
dilated, but differs in having very broad and short rostral
ae and a greatly enlarged tooth posterior to the postocular
tooth.
Paramithrax (Leptomithrax) brevirostris, sp. n.
Carapace subtriangular, without spines on its upper surface,
but covered with small scattered tubercles. Antero-lateral
margins with five spines (not including the postocular). Spines
of rostrum very short, triangular, and acute. Basal antennal
joint with two prominent spines at its distal end. Anterior
legs (in the female) slender; arm minutely spinulose above;

the female) smooth, distinct. Length of carapace to base of
rostrum 1? inch.
Hab. ie
The form and extreme shortness of the spines of the rostrum
serve to distinguish this species from its congeners.
Paramithrax (Paramithrax) spinosus, sp. n.
(Pl. IV. fig. 5.)
Carapace subpyriform ; surface covered with small scattered
granules, and with spines disposed as follows—an acute
spine, followed by a rounded tubercle, on the gastric region, a
bituberculated prominence on the cardiac region, two spines
on each branchial region, a spine on the intestinal region, and
a very small spine on the posterior margin of the carapace.
The spines of the upper orbital margin are blunt ; and posterior
to them, on the antero-lateral margins, are one or two small
spinules. Spines of rostrum divergent and acute. Pterygo-
stomian regions granulated. Basal antenual joint rather nar-
row, longitudinally sulcated, and with a small tubercle at its
antero-external angle. Merus joint of outer maxillipedes small
and without a distinct notch at its antero-internal angle.
Anterior legs (in the male) robust; arm granulated on its
outer surface, and with two or three spinules above; wrist
spinulose above and with a dentated crest on its outer surface ;
palm compressed and perfectly smooth; fingers arcuate and
meeting only at the tips, which are denticulated and acute ;
there is a-strong tubercle on the inner margin of the upper
finger near the base. Ambulatory legs slender. Postabdo-
minal segments distinct, the terminal one the longest. Length
to base of rostrum 2 inch.
Hab. Norfolk Island, on a fish taken at a depth of 23
fathoms (H.M.S. ‘ Herald.’)
One male individual is in the collection. This species, in
the form of the merus joint of the outer maxillipedes, ap-
proaches Acanthophrys. It comes near in external appearance
to specimens in the Museum collection from Australia and
New Zealand, which I formerly referred to P. Gaimardt,
M.-Edwards, but now to P. sternocostulatus, M.-Edw., but
differs in the number and position of the spines on the bran-
chial regions and lateral margins, and in the much slenderer
basal antennal joint, which has not two spines at its distal
extremity.

Paramithrax (Paramithrax) halimoides, sp. n.
Carapace elongated, and scarcely narrowing anteriorly, with
five long spines in a longitudinal median series, of which two
are on the gastric, one on the cardiac, and one on the in-
testinal region, and one on the posterior margin directed back-
ward ; also one on each branchial region. ‘The spines of the
rostrum are long, acute, and slightly divergent. The pre-
ocular spine is prominent and acute, the postocular large and
lamellate, and it is followed by a smaller prominence on the
hepatic region. Basal antennal joint rather narrow, with two
spines, of which one at the antero-external angle is prominent
and directed outward. Merus joint of the outer maxillipedes
with a notch for the insertion of the following joint at its
antero-internal angle; exognath narrow. Anterior legs (in
the male) small and slender ; arm with a slight dentated crest
on its under surface, wrist cariated above, palm compressed,
and fingers straight and acute. Ambulatory legs slender,
with a prominent spine at the distal end of the merus joints.
Postabdominal segments (in the male) distinct, slightly tuber-
culated in the middle line. Length of carapace to base of
rostrum about 2 inch.
Hab. Fastern seas (77.M.8. ‘ Samarang’).
- This species is mentioned but not described, under the name
of Ohorinus halimoides, by White, in the ‘ List of Crustacea in
the British Museum,’ p. 123 (1847) ; and De Haan’s Halimus
incisus is referred to doubtfully as synonymous with it; but
it has nothing to do with that species, which belongs to the
genus Pugettia, and has recently been received by the British
Museum from the Japanese seas. It is not referred to in the
‘Zoology of the Voyage of the Samarang.’ It is distin-
guished from Paramithrax aculeatus (Chorinus aculeatus,
M.-Edw.), and Paramithrax longispinus (De Haan), and
P. acanthonotus and P. verrucosipes, Ad. & White, all of
which have been referred to Chorinus, by the number and
disposition of the spines of the carapace. I believe it to be
necessary to restrict the genus Chorinus to the single species
comprehended in Milne-EKdwards’s first section of the genus,
the West-Indian C. heros (Herbst).
Acanthophrys paucispina, sp. n.

gastric region, another on the cardiac region, followed by a
prominent spine, and a tubercle on the intestinal region ; there

are two spines on each branchial region. Over the eye is a
very prominent and triangular spine ; the postocular is smaller
and blunt, the rostral spines are acute and divergent, the
basal antennal joint is very large, with a spine, directed for-
ward, at its antero-external angle. Outer maxillipedes smooth ;
ischium joint very narrow ; merus joint large, concealing the
following: joints, without a notch at its antero-internal angle,
and much produced and rounded at its antero-external angle ;
exognath very large, broader than the ischium joint. Ante-
rior legs (in the male) smooth ; palm compressed and carinated
above, fingers nearly as in Paramithrax spinosus. Ambula-
tory legs slender and smooth, terminal joints slightly curved.
Postabdominal segments (in the male) smooth, distinct.
Length of carapace to base of rostrum nearly 4 inch.
Hab. Fiji Islands, Ovalau (H.M.S. ‘ Herald’).
I propose to restrict the genus Acanthophrys to the species
having the outer maxillipedes of the form described above. I
have not seen the type specimens of either of M. A. Milne-
Edwards’s species ; but this character (if we may judge from
the figure) seems to exist in his Acanthophrys cristimanus ;
and it certainly does in a specimen which I refer to it from
the Marquesas in the British-Museum collection, and which
is labelled “ Pisa cristiémana.” 'There seems to be no other
positive character to distinguish this genus from Paramithrax.
One male individual of A. paucispina is in the collection.
Pisa carinimana, sp.n. (PI. IV. fig. 6.)
The carapace of this pretty little species is subpyriform,
closely pubescent, and with a few longer curled hairs. There
are six very obscure tubercles or granules disposed in two
transverse series of three each upon the gastric region, and
two tubercles on the branchial regions, besides the small
lateral epibranchial spine; the cardiac region is very convex,
elevated, and rounded; and there is a small median tubercle
upon the posterior margin of the carapace. The upper orbital
margin projects considerably ; and the hiatus in it encloses a
small tooth. Behind the postocular tooth or lobe is another
small tooth. There is a row of granules on the pterygosto-
mian regions. ‘The spines of the rostrum are rather long,
slender, and divergent from a point at some distance above
their base. The anterior legs in the male are rather small;
arm granulated on its upper, outer, and lower margins ; wrist
obscurely carinated on its outer surface; palm compressed,
carinated above and below, and longitudinally faintly suleated
on its outer surface. The second pair of legs are much longer
than the succeeding. Fingers denticulated on their inner

margins, and nearly straight. All the ambulatory legs are
slender, cylindrical, and unarmed. Length to base of rostrum
5 lines, breadth 44 lines.
Hab. Canaries (R. MacAndrew, Esq.).
This species shows a relation to Hyastenus in its greatly
elongated second legs. In the form of the rostrum it ap-
proaches P. ertnacea, A. M.-Edw., a West-Indian species.
It differs very markedly from the Micropisa ovata, Stimpson,
from the Cape-Verds, as figured by M. A. Milne-Edwards,
in its slenderer, more divergent rostral spines, narrower cara-
pace, and longer second legs. Specimens both of M. ovata
and of M. violacea, A. M.-Edwards (the latter from W. Africa),
are in the Museum collection, and have so great an affinity
with the species of Rhodia, Bell, and Herbstia, that I think
it will be impossible to maintain the genera Micropisa and
Rhoda as distinct from Herbstia.
Hyastenus (Chorilia) gracilirostris, sp. n.
(PL. IV. fig. 7.)
Carapace subpyriform, with three spinules in a longitudinal
median series on the gastric region, a strong conical spine on
the cardiac, a tubercle on the posterior margin, and two spines
on each of the branchial regions, of which the larger occupies
the usual position of the lateral epibranchial spine. Spines
of the rostrum very slender and divergent. Basal antennal
joint rather broad, and with only a small tubercle at its antero-
external angle. Merus joint of outer maxillipedes small,
transverse. Anterior legs rather small; arm and wrist
slender; palm compressed; fingers arcuate and meeting only
at the tips, which are denticulated and acute. Ambulatory
legs very slender, the first pair much the longest. Postab-
dominal segments distinct. Length of carapace to base of
rostrum about 3 inch.
Hab. Fiji Islands, Nairai (H.M.S. ‘ Herald’).
One male example is in the collection.
This species differs from all its congeners in the disposition
of the spines and tubercles of the carapace.
Pseudomicippe? varians, sp.n.? (PIV. fig. 8.)
I designate by this name, with much hesitation, two speci-
mens, male and female, in the British Museum. ‘They agree
with one another in the characters of the orbital and antennal
region, and in the number and disposition of the tubercles of
the carapace, and also in these particulars with the figures and
description of Pseudomicippe tenuipes, A. Milne-EKdwards.
There do not exist, however, on the ventral surface of the
Spectes of Maioid Crustacea. 13
cephalothorax the granulated crests mentioned by A. Milne-
Edwards. Moreover these specimens differ very remarkably
in the form of the rostrum from one another. In the female
the gastric region is very convex and the rostral spines de-
flexed and short, as in the other species of Pseudomicippe,
whereas in the male they are much longer, slender, and nearly
horizontal. The anterior legs, as usual in the male sex, are
more developed, palm larger and compressed. It seems scarcely
possible that these specimens, which were collected on the
same occasion and at the same locality, can belong to distinct
species; and if not, it is very remarkable that the deflexed
rostrum, which is one of the principal characters of the genus,
should fail in the male sex in this particular species. Length
of carapace to base of rostrum (in the male) 7 lines.
Hiab. Shark’s Bay, Western Australia (H.W.S. ‘ Herald’).
Paramicippe afjinis, sp. n.
Carapace suboblong, deeply concave on the hepatic regions,
surface uniformly and evenly granulated ; on the gastric region
are two somewhat larger granules, placed one behind the
other, and followed by one on the cardiac region; there is also
one on each branchial region ; the lateral and posterior margins
are granulated ; the fissures of the upper orbital margins are
very small; the rostrum is broad, spatulate, obliquely de-
flexed, with a small triangular notch at its distal end, and
with its antero-lateral angles rounded, without teeth or
spines. ‘The anterior legs (in the female) are very small and
smooth; the ambulatory legs are densely hairy. Length
about 6 lines.
Hab. Bass’s Straits (H.M.S. ‘ Challenger’).
The single example (a female) was found among the
‘Challenger’ collection of fishes, and is very nearly allied to
P. platipes, Riippell, with which P. bécarinata, Ad. & White,
and Micippe hirtipes, Dana, are probably identical. It differs
in its more evenly granulated carapace, the absence of the
spine on the antero-lateral margins of the rostrum, and the
more densely hairy legs.
Micippe parvirostris, sp.n. (PL. IV. fig. 9.)
Carapace triangulate-oblong, narrowing anteriorly ; its
whole surface covered with close-set but very prominent
granules, which tend to become small spinules; rostrum com-
posed of two very small, truncated, subvertically deflexed
spines. The lateral margins are armed with six spines, in-
cluding the postocular, which is bifid. The sides of the body,
beneath the lateral marginal spines, are granulated, like the
14 Mr. E. J. Miers on new or little-known
surface of the carapace. The eye-peduncles are very long,
compressed, smaller at the distal end, with a small blunt tooth
on their anterior margin. The basal antennal joint is but
moderately enlarged, with a very small spine at its antero-
external angle; and the two following are somewhat dilated
and compressed. Anterior legs (in the female) very small ;
arm and wrist granulose, palm and fingers smooth. Ambu-
latory legs robust ; merus joints slightly granulated. Post-
abdominal segments (of the female) distinct. Length 63
lines.
Hab. South Australia, Port Lincoln (Mus. Zool. Soc.).
This species is remarkable for the length and mobility of
the eyes, the smallness of the basal antennal joint, the non-
definition of the lower orbital wall, and the smallness of the
rostrum. One female example is in the collection.
Periceride.
TYLOCARCINUS, Miers.
The genus Tylocarcinus is nearly allied to Microphrys,
M.-Edwards (Milnia, Stimpson), and to Tiarinia, Dana, but
differs from them both in the very slender basal antennal
joint, the distal spine of which is short, as in Z%arinia, and is
not visible in a dorsal view; from the former genus it is further
distinguished by the narrow and elongated carapace, and from
the latter by the divergent rostral spines.

Carapace subpyriform and covered with rounded tubercles ;
of these, two are placed in the interorbital space, four in a
transverse series on the front of the gastric region, followed
by three in a triangle. There are three, similarly disposed,
on the cardiac, two on the intestinal region, three on the poste-
rior margin, three or four on the front and two on the hinder
lobe of each branchial region, and about six on the lateral
margins. ‘The spines of the rostrum are acute, rather short,

Postabdominal segments smooth, distinct. Length of carapace

Hab. Fiji Islands, Ngau, 'Totoya, Ovalau; Conway Reef
(H.M.S. ‘ Herald’).
The tubercles of the carapace are larger posteriorly, and
are most distinct in the oldest individuals. In some examples
the carapace is narrower and the rostral spines are longer ;
but these are not characters confined to one or the other
sex. ‘This species inhabits the coral reefs.
To facilitate the identification of the types of this new
genus, I have given at length the description of the above,
which I refer with some hesitation to the Cancer styx of
Herbst. It is certainly the species figured by M. A. Milne-
Edwards (/.c.) as Microphrys styx.
There is an adult male from the Mauritius in the British-
Museum collection, which differs from an adult male of the
species described above only in the greater enlargement of the
hands, and in the greatly arcuated fingers, which meet only
at the tips. Jam not disposed to regard it as distinct, since
M. A. Milne-Edwards has noted that P. stya is distributed
throughout the Indo-Pacific region.
Tylocarcinus gracilis, sp. n.
Carapace elongate-pyriform, surface covered with granules
and small tubercles. On the front of the gastric region are
several small granules followed by four in a transverse line ;
the branchial, cardiac, and intestinal regions are very indis-
tinctly tuberculated. The spines of the rostrum are long, very
slender, and divergent nearly from their base. The spines
on the third and fourth joints of the first pair of ambulatory
legs are long and acute.
Hab. “ Eastern seas” (H.M.S. ‘ Herald’).
This species differs from the foregoing principally in the
much narrower and less distinctly tuberculated carapace, and
in the form of the rostrum, and may perhaps prove to be only
a variety of it; the spines of the rostrum are in 7’ gracilis
more than half the length of the carapace; in 7’. sty# they are
much less than half its length.
Othonia quadridentata, sp. n. (Pl. V. fig. 1.)
Carapace rather broadly ovate, and smooth, without any
trace of tubercles or granules. Lateral margins armed with
four well-developed acute spines, without any trace of the fifth
and sixth spines, which are observable in other species of this
16 Mr. E. J. Miers on new or little-known
genus. Basal antennal joint not dentated, or with a single
small tooth on its anterior margin. Anterior legs (in the
female) small and weak. Ambulatory legs smooth, without
tubercles or spines. Postabdominal segments (in the female)
distinct. Length of carapace about ? inch, breadth between
the third and fourth lateral marginal spines 3 inch.
Hab. West Indies (Scrivener).
There are in the British Museum the carapaces of two
individuals (sex unknown), which differ only in their some-
what greater proportional breadth. The length of the larger
individual is about 1 inch and 4 line, the breadth 114 lines.
The colour of these carapaces is greenish upon a pale ground,
the green hue predominating on the anterior portion and form-
ing reticulations upon the back and sides of the carapace.
Traces of the same reticulations are visible on the sides of the
carapace in the typical specimens of O. quadridentata.
That all these examples belong to the same species can
scarcely be doubted; the greater breadth of the carapace in
the two last-mentioned may be due to age or sex. This
species is distinguished from all its congeners by the non-
existence of the fifth and sixth lateral marginal spines, even
in a rudimentary condition. The smoothness of the carapace
further distinguishes it from all the species known, except
O. levigata, A. M.-Edwards. These may appear but slight
diagnostic characters ; but this species is more distinct from
its nearest allies than O. Lherminiert (for example) is from
O. levigata or O. sexdentata from either. There appears to
be no alternative between separating the species on such slight
differences and uniting all, both from the eastern and western
American coasts.
Parathoé rotundata, gen. et sp.n. (Pl. V. fig. 2.)
Carapace subtriangular, rounded behind, and indistinctly
tuberculated; the gastric and cardiac regions are distinctly
defined and nearly smooth ; there are four or five indistinct
rounded elevations on the branchial regions, and two tuber-
cles on the posterior margin. ‘The rostrum is very small,
little prominent, and notched at its extremity. The anterior
legs (in the male) are robust; arm and wrist smooth; palm
enlarged, smooth and compressed; fingers arcuate, and meeting
only at the tips, which are excavated. On the inner margin
of the mobile finger, near its base, is a small tubercle. The
ambulatory legs are robust, with the merus joints strongly
tuberculated. The rather narrow basal antennal joint is un-
armed at its distal end. The postabdominal segments (in the
male and female) are smooth and distinct. Length 33 lines.

Hab. Totoya, Fiji Islands (4.M.S. ‘ Herald’); Port
Curtis (H.M.S. ‘ Herald’).
Notwithstanding the small size of the specimens, they have
all the appearance of being adult.
There is in the Museum collection a female example from
the Gulf of Suez (MacAndrew), which seems to belong to this
species.
The genus Parathoé, as its name imports, is most nearly
allied to Zhoé, Bell, but differs in the much narrower basal
antennal joint, and in the non-dilatation of the merus joints
of the ambulatory legs. From Mithrax, which it may be
supposed to represent in the Indo-Pacific seas, it differs in
the first-mentioned character and also in the form of the
carapace and absence of antero-lateral marginal teeth.
Parthenopide.
LAMBRUS.
The genus Lambrus is one which is remarkable for the
number and variety of its species; and it greatly stands in
need of revision. Several of the described forms are insuffi-
ciently characterized ; and it is therefore not without consider-
able hesitation that 1 have described so many below as new
to science. The genus can be conveniently divided into
two subgenera :—the first containing the typical Lambdri*, in
which the carapace is rhomboidal rather than triangular, or
rounded behind, and the anterior legs greatly elongated, con-
siderably more than twice the length of the body, and more
or less spinose; the second containing those forms in which
the carapace is subtriangular, somewhat produced over the
bases of the ambulatory legs at its postero-lateral angles, with
the posterior margin straight or nearly so, and the anterior
legs shorter, rarely exceeding twice the length of the carapace.
In the first of these subgenera the species may be further
subdivided, according as the merus joints of the ambulatory
legs are or are not spinulose along their margins. ‘The second
subgenus, in the shortness of the anterior legs, approaches Par-
thenope, and contains several forms which have been described
as members of that genus. I believe it to be more conveni-
ent, however, to restrict the designation Parthenope to the
long-known P. horrida, Lam., and its near ally P. spinosis-
stma, A. M.-Edwards, which are characterized by the greater
development of the basal antennal joint and of the spines of
the ambulatory legs.
* The type of this subgenus is LZ. /ongimanus, and not, as stated by a
lapsus calama in Journ. Linn. Soc. xiy. p. 672, L. erenulatus, Saus.

| 18 Mr. E. J. Miers on new or little-known
I may here observe that Dr. Stimpson has proposed to
separate under the name of Platylambrus a certain number
of Lambrt, characterized by the excavation of the subhepatic
and pterygostomian regions (the excavation forming an afferent
branchial channel) ; but this peculiarity is developed in species:
otherwise so dissimilar, and these species pass so completely
into the forms in which this channel is not developed, that I
think the proposed character can scarcely be retained as a
generic distinction.
§ 1. Carapace usually rounded behind (the postero-lateral margins not in a
line with the posterior margin); anterior legs greatly elongated and
usually spinose. (‘Typical Lambrus.)
a. Merus joints of the ambulatory legs spinulose along their upper or
under margins, or both margins.
Lambrus longispinus, sp. n.
Carapace broader than long to base of rostrum, spinose and
tuberculate above; there are four prominent spines in the
middle line, of which three are on the cardiac and one on the
gastric region ; in front of the latter are two smaller spines ;
and there are also two on the posterior margin. On the bran-
chial regions are several small spines, principally arranged in
two oblique series on each side, and one larger spine. On the
antero-lateral margins are about nine small, blunt, very faintly
laciniated teeth, increasing in size posteriorly, and on the
postero-lateral margins two long spines. The rostrum is
prominent, triangular, acute, and obliquely deflexed. ‘The
anterior legs have ten or twelve spines on the anterior* mar-
gins of the arms, alternating in size, except the three or four
nearest the distal end, which are small; also three very pro-
minent spines on the upper surface, and two or three on the
posterior margin of the arm; on the anterior margin of the
upper surface of the hands are seven larger, granulated, trian-
angular spines and two or three smaller, and four larger and
three smaller on the posterior margin. The lower surface of
the arms, wrists, and hands is covered with rather large,
rounded, granulated tubercles. ‘The merus and sometimes the
following joints of the ambulatory legs are compressed and
dentated. Length to base of rostrum about 1 inch, breadth
nearly 1 inch 2 lines.
Hab. Shanghai (Jamrach).
This species is allied to the Japanese LZ. validus and L.
* In describing the species of Lambrus I have regarded the large ante-
rior legs as fully laterally extended; consequently the terms “anterior ”’
and ‘ posterior” are used for the margins of these limbs, instead of
“inner” and “outer,” the latter terms being often misleading.

laciniatus, De Haan, and also apparently to the West-Indian
L. Pourtalesti and L. fraterculus, Stm., but differs in the
longer spines of the carapace and the form and disposition of
the tubercles on the under surface of the anterior legs, and in
other characters.
There is in the British Museum a female from Australia
(Stwtchbury) in very bad condition, which probably belongs to
this species, but differs in the broader, more obtuse and
rounded rostrum, and the shorter spines on the posterior margin
of the arms. If distinct, it may be named L. latirostris.
Lambrus Holdsworthi, sp.n. (PI. V. fig. 3.)
Carapace broader than long to base of rostrum; branchial
and cardiac regions covered with small, scattered, unequal
tubercles ; there are three blunt prominences or spines in a
median longitudinal series, of which one is on the gastric and
two are on the cardiac region. ‘The antero-lateral margins are
armed with about ten small tubercles, after which follow, on the
postero-lateral margins, three prominent triangular flattened
spines, which are granulated on their margins; the last of these
isthe smallest; the posterior margin is tuberculated, three of the
tubercles being larger. The rostrum is prominent, triangular,
smooth, and slightly concave above. The anterior legs have
the arms tuberculate and spinose on their upper surface and
auterior and posterior margins ; of these, four on the anterior
margin, three to four on the upper surface, and two to three
on the posterior margin are larger; the wrist is tuberculated
on its upper surface and armed with spines, similar to those
of the hand, on its outer margin; the upper surface of the
hand is flat and smooth, but has a few irregular tubercles near
its posterior margin; on its anterior margin are about a dozen
flattened triangular spines, which increase in length distally ;
on the posterior margin are about nine flattened triangular
spines, of which four are larger; the inferior surface of wrist
and hand has a longitudinal series of small tubercles, but is
elsewhere smooth. The merus joints of the ambulatory legs
are spinulose on their upper margins. Length to base of
rostrum about 6 lines, breadth about 7 lines.
Hab. Ceylon (E. W. H. Holdsworth, Esq.).
This species is apparently most nearly allied to L. lacinia-
tus, De Haan (among the forms having the merus joints of
the ambulatory legs spinulose above), but differs in the form
and number of the spines of the anterior legs. In L. Holds-
worthi the spines of the outer margin of the hand are much
broader and in contact at their bases. I may notice that the
subhepatic region is channelled, but the channel does not lead
Q%
20 Mr. E. J. Miers on new or little-known
to the afferent branchial aperture, but is continued beneath
the margin of the carapace.
All the specimens are females. The smallest of all (length
4 lines) bears ova. In two of intermediate size, the smaller
tubercles of the carapace are nearly obsolete.
Lambrus levicarpus, sp.n. (PI. V. fig. 4.)
Carapace scarcely broader than long (to base of rostrum),
with numerous tubercles on its upper surface, and four small
spines in a longitudinal median series, of which one is on the
gastric and three are on the cardiac region ; there are also two
spines on each branchial region. The lateral marginal tuber-
cles (about twelve in number) are small, and similar to those
of the surface of the body. The front is moderately promi-
nent, triangular, acute, with a tubercle on each side near the
base. Anterior legs with the arm spinose and _ tuberculate
above, the teeth granulated and principally disposed in three
longitudinal series of alternately larger and smaller ones on
the anterior and posterior margins and upper surface ; there are
about seven larger teeth on the anterior and posterior margins,
and four on the upper surface; the wrist 1s spinose on its
posterior margin, granulated on the anterior, and smooth
above ; the anterior margin of the hand is armed with sixteen
to eighteen granulated tubercles, which are larger toward the
distal extremity ; the upper surface is flat and smooth, with
about a dozen tubercles in an irregular longitudinal series ; on
the posterior margin are about seven larger granulated tuber-
cles alternating with smaller ones. The under surface of the
anterior legs is perfectly flat and smooth, and the inner margin
of the under surface of the hands is finely granulated. The
tubercles on the merus joints of the ambulatory legs are very
small. Length (to base of rostrum) and breadth about
5 lines.
Hab. Eastern seas (H.M.S. ‘ Samarang’).
This species is remarkable for the perfect smoothness of the
under surface of the anterior legs and of the upper surface of
the wrists. It presents also another character which is rarely
found among the species of Lambrus ; the basal (7. e. the real
second) joint of the outer antenne is larger than the next
joint.

of the median one ; interocular space smooth, concave. An-
terior legs greatly elongated ; arm spinulose above and on its
anterior margin; on the posterior margin are seven longer
spines, alternating with smaller ones; wrist minutely tuber-
culate above, and with six or seven alternately larger and
smaller spines on its posterior margin; hand spinulose or
tuberculate above, its anterior margin with fifteen to eighteen
compound or branching spines, which increase in size towards
the distal extremity, posterior margin with five to eight
longer, alternating with smaller spines ; under surface of arm
and wrist nearly smooth, of hand minutely granulated or
tuberculate. Spinules of the merus joints of the ambulatory
legs very small. Penultimate joint of the postabdomen of the
male armed with a spine or tubercle. Length of an adult

I have described this species at length because, although it
is probably the species intended by M.-Edwards in his short
diagnosis of LZ. longimanus, it is possibly not the Cancer
longimanus of Linneus. IJ may here note that the specimens
in the British Museum from India, Singapore, and the Philip-
pines, referred by White (‘ List Crust. B. M.’ p. 11) to Lam-
brus longimanus, appear to belong to Lambrus affinis, A. M.-
Edwards. This latter species has evidently a very wide
range, and may perhaps be identical with the long-pre-
viously described LL. pelagicus, Riippell, as it differs only in
the smoothness of the arms on the front part of their upper
surface, and in the greater prominence of some of the tuber-
cles on the posterior (outer) margin of the hand; and speci-
mens of both varieties are in the British Museum from Zan-
aibar.
b. Merus joints of the ambulatory legs not armed with spines or
distinct tubercles.
Lambrus deflexifrons, sp.n. (PI. V. fig. 5.)
The carapace is strongly constricted behind the orbits, with
the cardiac region very convex, and with an oblique but
shallow sulcus on the branchial regions, and is covered with
closely-set small tubercles; the antero-lateral margins are
22 My. E. J. Miers on new or little-known
unarmed ; but there are two larger tubercles or small spmes on
the postero-lateral margins. ‘The rostrum is vertically de-
flexed, triangular, and granulated above. The basal antennal
joint is very small; the epistoma is large ; the subhepatic and
pterygostomian regions are not channelled. The anterior:
legs have the arm rounded and tuberculate above, with
small spines on its anterior margin; the wrist is tuberculate ;
the hand with a few tubercles on its upper surface, the ante-
rior margin armed with about ten, and the posterior with four
granulated spines. The under surface of arm, wrist, and hand
is closely granulated. The ambulatory legs are smooth, and
are not compressed and cristate as usual in the genus.
Length to base of rostrum, and breadth, nearly $ inch.
Hab. Ceylon (EL. W. H. Holdsworth, Esq.).
The vertically deflexed rostrum and carapace, devoid of
spines on its surface and anterior margins, and non-com-
pressed ambulatory legs are characteristic of this species. It
seems to be allied to L. gracilis, Dana, a species from the
Fijis, in the form of the carapace and legs ; but in that species
the carapace has a spine on the cardiac and each branchial
region, and elsewhere appears to be smooth.
Lambrus hoplonotus.
Lambrus hoplonotus, Ad. & White, Zool. Samarang, Crust. p. 35, pl. vil.
fig. 3 (1848).
In the typical form of this species, as exemplified by the
specimen bearing White’s label in the Museum collection, the
carapace is covered with large, rounded, granulated tubercles,
and the spines of the antero-lateral margins are small, obtuse,
and rounded, the last only (lateral epibranchial spine) being
greatly elongated. The rostrum is very small, triangular,
and acute. The eye-peduncles are short and thick. The
upper surface of the arm, wrist, and hand is covered with
irregularly disposed rounded tubercles; the spines of the
anterior and posterior margins of the hand are straight and
granulated at base ; the under surface of the arms is strongly
tuberculated. White’s specimen is labelled only as from the
“« Hastern Seas.”
Below are described three very distinct forms which are
provisionally regarded as varieties of L. hoplonotus. They
are, unfortunately, represented each by only one, two, or three
specimens ; and a larger series might either establish them as
distinct species, or show that L. hoplonotus is a widely distri-
buted form, subject only to local variations.
Species of Matoid Crustacea. 23
Var. granulosus.
Carapace considerably broader than long, granulated above,
the granules closest upon the surface of the branchial, gastric,
and cardiac regions. Antero-lateral margins with about a
dozen small obtuse teeth, followed by a very long acute spine,
to which succeeds a shorter spine on the back of each of the
branchial regions; the posterior margin of the carapace be-
tween these spines is granulated. Rostrum triangular, not
deflexed, and minutely granulated on_ its lateral” margins.
Anterior legs elongated ; arm with about five long spines on
its posterior margin, alternating with very small spines, with
about four tubercles on its upper surface, in a longitudinal
series, and twelve to fourteen unequal tubercles on its anterior
margin ; wrist granulated above, and with four or five spines
on its posterior margin; hand with about six long spines,
alternating with smaller ones, on its posterior margin, with
about four distant tubercles in a longitudinal series on its
upper surface, and nine or ten spines on :ts anterior margin,
increasing in length toward the distal extremity ; the under
surface of ar m, wrist, and hand is nearly smooth. Length of
carapace to base of rostrum 5 lines, breadth 6 lines.
Hab. Philippine Islands, Corregidor (Cuming).
The specimens described above have been referred by
White, in the ‘List of Crustacea in the British Museum,’
p. 12 (1847), to Z. serratus, M.-Edwards; but they differ in
nearly all the characters mentioned in his brief pee
They are much more nearly allied to the typical Lambrus
hoplonotus of Adams and White, and may, indeed, be the
young of that species, but differ in the much smaller eranules
of the carapace, and much fewer tubercles on the upper sur-
face of the hands. In both varieties the margins of the cara-
pace and anterior legs are clothed with close long hairs.
Var. longioculis. (PI. V. fig. 6.)
This variety is allied to the preceding and to the typical
L. hoplonotus; but the tubercles of the carapace and of the
upper surface of the anterior legs are much longer, and, like
the teeth of the antero-lateral margins, tend to ‘become veri-
table spines. The lateral epibranchial spine is_ relatively
much shorter than in L. hoplonotus. The rostrum is perfectly
smooth above and upon the lateral margins. ‘The eyes are
remarkably long for a species of this genus, and project
beyond the orbits, the outer margins of which are deeply sul-

Two specimens, males, are in the collection, dredged in
17 fathoms, on a bottom of coarse sand and shells.
Var. planifrons. (PI. V. fig. 7.)
In this variety the carapace is covered with numerous,
small, rounded tubercles or granules, and with rather larger
rounded tubercles on the antero-lateral margins. The lateral
epibranchial spine (in an adult female) is rather short. The
eyes are short and thick. The orbital margins are distinctly
granulated ; the rostrum is triangular, rather prominent, flat,
smooth, and scarcely acute at its distal end. The upper
surface of arm, wrist, and hand are tuberculated. The spines
of the anterior and posterior margins of the hands are straight,
flattened, and rather broad and not granulated at base; the
under surface of the anterior legs is nearly smooth. Length
of carapace to base of rostrum nearly 3 inch.
Hab. Ceylon (LH. W. H. Holdsworth, Esq.).
The form of the rostrum, of the spines of the hand, the
granulations of the carapace, and the short lateral epibranchial
spine serve to distinguish this variety.
There are some young individuals from the Gulf of Suez
(MacAndrew) which differ from all the preceding forms in
the existence of a small blunt tooth on each side of the ros-
trum, which is suleate above; but these I will not at present
designate by a distinct name.
Lambrus curvispinus, sp. n.
This is a species belonging to the same section of the genus
as L. hoplonotus, and closely allied to it. It has the granules
of the upper surface of the carapace small and subspiniform.
The rostrum is very small, acute, and granulous on its lateral
margins. The teeth of the antero-lateral margins are much
longer and become well-developed spines as they approach
the lateral epibranchial spine, which is extremely long. The
inner margin of the arms is minutely spinulose ; and the spines
of the anterior margin of the hands are long, acute, and
curved upward and forward at the tips. Length of carapace
to base of rostrum ? inch.

§ 2. Carapace usually produced over the bases of the ambulatory legs at its
postero-lateral angles, and with the postero-luteral margins nearly in a
straight line with the posterior margin. Anterior legs shorter, margins
dentate, but rarely spinose. (Parthenopoides.)
Lambrus (Parthenopoides) erosus, sp. n.
(Pl. V. fig. 8.)
Carapace triangular, slightly produced over the bases of
the ambulatory legs, its postero-lateral angles forming a decided
angle with the straight posterior margin ; its surface is without
tubercles or spines, but is uniformly and deeply pitted and
eroded ; somewhat larger pits mark the interspaces between the
gastric, ” cardiac, and branchial regions ;_ the rostrum is small,
triangular, and deflexed. The inferior surface of the carapace
is similarly but more regularly pitted. The anterior legs are
robust and eroded; the arm greatly dilated; the hand with a
prominent, oblique, earcely dentated crest on its anterior
surface ; lower finger broad and triangular in shape. The
ambulatory legs are eroded and pitted like the body. Length
5 lines, breadth about 6 lines.
Hab. Eastern Seas (I.M.S. ‘ Herald’).
This species cannot be confounded with any other of the
genus known to ime.
Lambrus (Parthenopoides) expansus, sp. n.
CPI Y. fie. 9.)
Carapace subtriangular, and greatly produced at its postero-
lateral angles over the bases of the ambulatory legs; the gas-
tric and cardiac regions are very prominent; the surface of the
carapace behind and on either side of the gastric region is
very concave. ‘There are three obscure rounded tubercles on
the gastric region, an obscurely granulated ridge on the
branchial regions, parallel to the antero-lateral margins, and
a few small granulations on each side nearer the cardiac
region. The straight posterior margin of the carapace and the
lateral margins, near the postero-lateral angles, are minutely
denticulated ; the lateral marginal series of denticles are
continued forward onto the pterygostomian regions. The
front is rather prominent, slightly concave above, granulated
neat and obtuse at its distal end. The anterior legs are
smooth and not eroded above; arm with a series of closely-
set granulated teeth on its anterior mar gin; upper surface and
posterior margin obscurely granulated; hand very robust,
with five or six teeth on its anterior margin: posterior margin
uneven, but not toothed; fingers thick, smooth, and curved.
26 Mr. E. J. Miers on new or little-known
The under surface of the arm, wrist, and hand is obscurely
granulated. The ambulatory legs are compressed, but scarcely
denticulated. Length to base of rostrum 34 lines, breadth
55 lines. .
Hab. Madeira (fev. Rk. Boog Watson).
This species is distinguished by the great development of
the postero-lateral expansions of the carapace and the smooth-
ness of its upper surface and of the anterior legs, in which re-
spects it is distinguished from the L. rugosus, Stim., and L.
pulchellus, A. M.-EKdwards, both from the Cape-Verd Islands.
It would seem to be more nearly allied to the species very
shortly characterized by A. M.-Edwards under the name of P.
trigona, of which the habitat is not known; but that species
is described as having the arm strongly eroded.
A single male example is in the collection of the
Museum.
Cryptopodia spatulifrons, sp.n. (Pl. V. fig. 10.)
Carapace transversely triangulate, with the postero-lateral
angles truncated, everywhere punctate and granulated, the
granulations being largest and most conspicuous on the ele-
vated cardiac and branchial regions, and on the postero-lateral
and posterior expansions of the carapace. The branchial and
cardiac regions are much elevated ; there is a strongly marked
depression in the centre of the carapace ; and the surface of the
carapace behind the antero-lateral margins and posterior mar-
gin are concave ; the antero-lateral margins are denticulated
and the postero-lateral and posterior margins crenulated.
The rostrum is prominent, not deflexed, smooth, and of a
semielliptical shape, subacute at the extremity, and with a
series of submarginal punctures. ‘The anterior legs are very
robust ; surface smooth but coarsely punctured; the anterior
and posterior margins of the arm are produced into dentated
crests, the posterior expansion being greatly dilated towards
the distal extremity ; the oblique crest on the anterior surface
of the hand is armed with six prominent triangular teeth, the
posterior margin being three-dentated ; the under surface of
the anterior legs is coarsely punctulated and granulated. The
ambulatory legs are smooth, longitudinally carinated on their
upper and under surfaces. Length of carapace to base of
rostrum about 1 inch, breadth nearly 2 inches.

traction of the carapace behind the orbits. Moreover the
carine on the merus and ischium joints of the ambulatory
legs are not armed with spines as in C. contracta.
Cryptopodia spatulifrons, var. levimana.
There are in the British Museum two smaller specimens
(males) which probably belong to the same species as the one
described above. The carapace is tuberculated only upon the
elevated parts of the branchial and cardiac regions, and on the
posterior and postero-lateral expansions; elsewhere it is smooth,
scarcely even punctured. The upper surface of the arm and
hand is smooth; the lower is also smooth, except for a longi-
tudinal median ridge of granules. Of this variety one speci-
men was obtained on the coast of Borneo, the other is without
indication of locality. As the specimens are of smaller size,
they probably represent the younger condition of the species.
Ceratocarcinus spinosus, sp. n. (Pl. V. fig. 11.)
By this name I propose to designate a specimen of very
snall size, which may be immature, yet differs more remark-
ably from the type species of the genus (C. longimanus, Ad.
& White) than do the other described species, C. speciosus,
Dana, and C. dilatatus, A. M.-Edwards. The spines of the
rostrum, lateral margins, and gastric region are far longer than
in either of the species above mentioned ; and there is in addi-
tion a smaller spme upon each of the branchial regions, two
spines upon the wrist, and one at the distal end of the upper
margin of the hand and of the merus joint of each of the am-
bulatory legs. Length only 13 line.
Hab. Eastern seas (H.M.S. ‘ Herald’).
The specimen appears to be a female ; as in the other species
of the genus, the antenne are completely excluded from the
inner orbital hiatus.

In previous papers on Carboniferous Entomostraca we have
attempted to show, and critically examine, what has been
already done in investigating this interesting though some-
what difficult group of fossils.
In a paper published in May 1865*, we gave the result
of an examination of a series of specimens from Bavaria,

In July 1866, in another paper+, we discussed what
had been done by British authors, from the time of Ure
(1793) to that of M‘Coy (1844), our observations being
based, in several instances, on an examination of type spe-
cimens.
In 1867 we gave, in the ‘Transactions of the Geological

The list included a great many new species (discovered by
Mr. John Young and other Members of the above Society),
most of which have yet to be described and figured.
In 1870 one of us described some species (Carbonie &c.)
from South Wales §.
Lastly, in 1875||, we noticed some Russian specimens
presented to us by the late M. d’Kichwald, with a few from
the late Sir R. I. Murchison’s collection.
These papers, though slight, have helped to clear the way
for the description of new species, by showing what others
have done in this field of research, and what our opinion was
of the results of their work, with a view to the rectification
and unification of the synonymy, and to the determination of
numerous species not yet described.
Among other materials which have accumulated in our
many years’ study of Carboniferous Entomostraca is a large
suite of specimens belonging to a group of seven species,
hitherto referred to Cythere, but which apparently belong to
the genus Carbonia, established by one of us, in 1870, for
the reception of two species from the Coal-measures of South
Wales. It is proposed to give a brief account of the seven
species in the present paper.
The species in question have the form of ordinary Cythera,
but differ from them in possessing a circular muscle-spot near
the centre of each valve, after the manner of Leperditia.
The muscle-spot is commonly seen in casts as a slightly
raised tubercle. When the interior. of the carapace-valves is
exposed (which is not often), the spot appears as a shallow
excavation. In some of the ironstones of the west of Scot-

is white.
These Carbonic are from:—(1) the Calciferous Sandstone
or Lower Carboniferous series of Scotland; (2) the coal-
bearing strata of the Carboniferous Limestone series of the
same country; and (3) the Coal-measures of England,
Wales, and Scotland. They occur in bituminous shales, in
blackband and clayband ironstones, in parrot-coals, and in
impure limestones. Individuals of some of the species, more
particularly of C. fabulina, appear to have swarmed in the
waters in which these deposits were formed. Some of the
strata are literally full of their remains. They are essen-
tially characteristic of the carbonaceous portions of the Car-
boniferous System. Wherever conditions suitable for the
laying down of Coal-measures prevailed, there these Ento-
mostraca flourished, almost to the exclusion of species of other
genera.
It ought to be mentioned that we are greatly indebted, for
multitudes of specimens from the west of Scotland, and for
much information as to the distribution of the species, to Mr.
John Young, of Glasgow, who is also the discoverer of
several of the species here described. For other specimens
we have to thank Mr. James Armstrong and Mr. James
Thomson of Glasgow, Dr. Rankine of Carluke, Mr. Grossart
of Shotts, Mr. E. W. Binney of Manchester, Mr. John Ward
of Longton, and other friends. Our examination of the very
numerous specimens collected by the Geological Surveyors
of Scotland has greatly enlarged our knowledge of this
genus.
Genus CARBONIA, Jones (1870).
Valves (as known) subovate, ovate-oblong, or elongate ;
anterior third usually smaller than the posterior; the right
valve slightly larger than the left, overlapping it some-
times along the middle portion of the ventral edge. Hinge-
line in the middle third of dorsal margin, more or less defined
between the anterior and posterior curved slopes of the dorsal
margin. Hinge simple. Muscle-spot circular, enclosing
three or four translucent spots or a lobed pattern; level or
slightly depressed on the outside, somewhat hollow within.
The valves are bent inwards, in some cases, near the muscle-
spots, and leave slight, subcentral, transverse furrows on the
cast.
The round and spotted muscle-mark, hollow within, is
characteristic of this genus.

Gythere ? fabulina, J. & K. Geol. Mag. 1870, vol. vii. p. 218.
1. Typical examples: length 35, 35, and =, inch.
More or less bean-shaped. Dorsal border arched, highest
behind ; anterior extremity more acutely rounded than the
posterior; ventral border straight or slightly incurved about
the middle, where the right valve overlaps the left. Height
more than half the length, sometimes fully two thirds. Dor-
sal and ventral aspects acutely ovate, widest behind. Surface
of most specimens smooth, but, in well-preserved valves,
pitted or rudely reticulate. A circular muscle-spot, subcen-
trally placed, is indicated externally in some examples; but it
is best seen in casts as a slightly raised spot or tubercle.
The above gives the characters of what may be taken as
typical examples of the species. Other specimens show dif-
ferences that appear of varietal value. The more important
of these are :—
2. Var. humilis. (Pl. IL. figs. 11-14.)
Elongate; dorsal border flatly convex; extremities rounded
and more nearly alike than in type specimens; ventral border
straight. Length ,, to 3; inch.
3. Var. inflata. (Pl. II. figs. 15-19.)
A thick-shelled, obese form, greater in width than in height,
and with the greatest width nearer the posterior end than in
other forms, which thus gives the dorsal and ventral aspects
of the carapace a subcuneitorm outline. Length 3, inch.
4. Var. subangulata. (Pl. II. figs. 20-23, and 24 ?.)
A gibbous, robust variety, of great relative height, with a
subangular dorsal border, and a very abrupt postero-dorsal
slope. Length ~> inch.
This variety is the largest of any of the forms of C. fabu-
lina. We figure with it a specimen from Millburn, Campsie,
which possesses a similar dorsal border, but less angulate,
and of very different relative height (fig. 24). This may ulti-
mately prove to belong to another variety.
C. fabulina has some resemblance to Cythere cuneola, J. &
32 Prof. T. R. Jones and Mr. J. W. Kirkby on .
K., of the marine beds of the Carboniferous Limestone series.
The latter is usually smaller than ordinary examples of Car-
bonia fabulina; and its valves have not the same ventral
overlap. Otherwise it is not always an easy matter to distin-
guish them.
Localities and Mode of Occurrence.-—At Pittenweem, in
the Calciferous Sandstone series, about 800 feet below the
base of the Carboniferous Limestone, C. fabulina occurs
in blackband ironstone, associated with Carbonia Ranki-
niana, J. & K., Leperditia scotoburdigalensis (Hibbert),
coprolites (possibly of Rhizodus), and the remains of Lepi-
dodendren.
At Millburn, Campsie, in the Carboniferous Limestone
series, it is found in impure limestone, together with Spzrorbis
carbonarius, Murch., and Stigmarian rootlets.
In the same formation at Crossgatehall, near Edinburgh, it
is met with in ironstone, with C. Rankiniana, C. pungens,
Spirorbis sp., and Lingula squamdformis, Phill.
In the Coal-measures at Provanhall, Lanarkshire, it is
found in black carbonaceous shale, with fish-remains and
plants.
Also in the same formation at Pirnie Colliery, Fifeshire, in
parrot-coal, with Carbonia Rankiniana, and associated with
the remains of the Amphibian Loxomma Allmani, Huxley,
and Fish, such as Strepsodus sauroides, Ag., Megalichthys
Hibberti, Ag., Ceelacanthus lepturus, Ag., Ctenodus sp., Pleura-
canthus gibbosus, Ag., and others; also Anthracomya pumila?,
Salter, Sptrorbis carbonarius, Murch. (attached in numbers to
drifted fragments of Sigillartia), and species of Antholites,
Lepidodendron, Calamites, and Stigmaria.
At the same locality, on another horizon, the variety inflata
occurs in coarse ironstone, which is filled with fragments of
Calamites, the Entomostraca being found within the filled-up
stems of the plants as well as in the matrix. A similar fact
was observed by Mr. John Young, who obtained a number of
examples of this species from the stem of a Lepidodendron,
at Possil, near Glasgow *.
Near Hylton, west of Sunderland, it is met with high in
the Durham Ooal-field, in a clayband ironstone, associated
with great numbers of an Estherta-like fossil, Ancylus ? Vinti,
Kirkby, Carbonia Rankiniana, J. & K., Beyrichia arcuata
(Bean), a species of Anthracomya, Plant-remains, and the
wings of Orthopterous Insects.
Other localities we give, with less detail, as follows :—

(Pl. TI. figs. 1-8.)
Cythere Rankiniana, J. & K. Trans. Geol. Soc. Glasgow, 1867, vol. ii.
p. 217.
Elongate, convex (usually), with the greatest height and
width at the posterior third ; height less than half the length.
Dorsal border sloping flatly from the posterior third towards
the anterior extremity, which is rounded; ventral border
straight or slightly incurved; posterior extremity rounded,
with an abrupt dorsal slope. Right valve rather the
largest, overlapping the left along the middle of the ventral
edge. Muscle-spot round or somewhat oval. A transverse
furrow is often shown on casts near the centre of each valve,
indicating a local contraction or partial thickening of the
shell at this spot. Surface usually smooth ; but in some speci-
mens a reticulation is discernible. Length j, to ;, inch.
The muscle-spot is rarely seen in this species; but the
transverse furrow (fig. 6) is often present in casts. ‘This fea-
ture also characterizes C. subula; and it has been noticed by
one of us in C. Agnes from the South- Wales coal-field.
This species ranges through the same portions of the Car-
boniferous series as C. fabulina; but, though widely distri-
buted, it is less abundant than that species.

A form very similar to, if not identical with C. Rankiniana
occurs in the Yellow Sandstone of Cultra, Holywood, Ire-
land, low down in the Carboniferous series (see Ann. &
Mag. Nat. Hist. ser. 3, vol. xviii. p. 49).
3. Carbonia subula, Jones and Kirkby.
(Pl. ILI. figs. 9-13.)
Cythere subula, J. & K. Trans. Geol. Soc. of Glasgow, 1867, vol. ii.
p- 222.
Very elongate, subcylindrical. Dorsal border slightly con-
vex; with an easy slope to the anterior extremity, which is
relatively broad, and projectiug above; and with a more
abrupt and deeper slope to the posterior extremity, which is
rounded or, in some examples, bluntly pointed ; ventral border
straight or very slightly concave where the right valve seems to
show a small overlap of the left. Dorsal and ventral aspects
lenticular. Surface smooth, so far as known. Length (4 inch)
nearly four times the height.
C. subula has the greatest length compared with height of
all the Carboniw. We, in a measure, assume that it belongs
‘to this genus, not having seen specimens with the muscle-
spot *, though casts showing the transverse furrow, as noticed
in C. Rankiniana and C. Agnes, have repeatedly occurred to us.
Moreover the general habit of the carapace is the same as in
the species previously described.
It is found in the Calciferous Sandstone and Carboniferous
Limestone series. It has not been seen in the Coal-measures,
* Mr. John Young informs us that he has seen what he considers to
be the muscle-spot of this species.

4. Carbonia scalpellus,n. sp. (Pl. II. figs. 14-17.)
Elongate and somewhat compressed. Dorsal and ventral
margins nearly parallel, the latter, however, being slightly
concave near the middle; the posterior extremity blunt and
subtruncate; the anterior extremity more produced and
rounded. Dorsal and ventral aspects flatly lenticular, with
the posterior end rather obtuse. Muscle-spot circular, rather
large, and placed a little towards the anterior end. Surface
smooth (?). Length +4 inch, .
This species is easily distinguished from C. subula by the
difference in outline, greater height, and less relative width of
the carapace.
It has been found only in the Coal-measures, at Ryhope
Colliery, near Sunderland, where it occurs in black shale and
ironstone, 592 feet below the base of the overlying Permian
deposits. The associated fossils are Carbonia fabulina, the
remains of Ganoid Fishes, Anthracosia sp., Lingula Crednert
(rare), Sigillaria, Lepidodendron, and Calamites.

Mytiloid, compressed. Dorsal border arched, highest be-
hind, sloping rapidly in front to the anterior extremity, which
is pointed; posterior extremity rounded; ventral margin
slightly concave, with a small overlap of the right valve.
Dorsal and ventral aspects compressed ; the width is less than
one fourth of the length; the height less than half the length.

(Pl. III. figs. 21-23.)
Cythere pungens, J. & K. Trans. Geol. Soc. of Glasgow, 1867, vol. ii.
- p. 222.
A small subeylindrical Carbonia, pointed at the anterior
end. Dorsal border flatly convex, highest behind, sloping
gently in front to a pointed anterior extremity ; ventral border
straight; posterior extremity bluntly rounded. Height con-
siderably less than half the length. Dorsal and ventral
aspects cuneiform, being nearly as wide as high behind, and
acutely pointed in front. Muscle-spot situate rather anterior
to centre of valve. Surface smooth, sofaras known. Length
zz inch.
This species is the smallest of the series here described ; and
though somewhat resembling C. secans, it can be distinguished
by its general outline being less Mytiloid, and by its wedge-
shaped dorsal and ventral aspects.
It is not a rare form in Scotch Carboniferous strata, but
is, as yet, of unknown occurrence in England.

7. Cythere? (Carbonia ?) bairdioides, n. sp.
(Pl. III. figs. 24, 25; 26 and 27 ?.)
We have specimens of a form from Pirnie Colliery, Fife,
and Craigenglen, Campsie, which may ultimately prove to
belong to Carbonia. Only few examples of it, however, have
occurred, and its muscle-spot has not been seen; so that for
the present we figure and notice it as a Cythere, with doubt.
Length +}; inch.
It simulates a Bairdia in outline, having a regularly arched
dorsal border, with one end rather pointed, the other rounded,
and a very slightly convex ventral border.
The Fifeshire specimens are much the largest, being +; inch
in length. A similar form, given to us by Mr. John Ward,
occurs in the Upper Coal-measures at Longton, Staffordshire.
We have given particulars of the mode of occurrence and
associated fossils of the Entomostraca which we have just
described, with some detail, as such facts bear on the question
of the physical conditions under which they existed. It will
have been seen that the fossils usually found with most of the
species are theremainsof Fishes, Amphibia (in a few instances),
Anthracosia and shells of that family, the ubiquitous Sp7-
rorbis carbonarius, and Plants (Ferns excepted). These are,
of course, the common fossils of the Palzeozoic coal-bearing
strata; and about their natural habitats we do not know much
after all. In two localities species of Lingula* are associated
with them. In another (where Carbonia fabulina attains its
largest development) Leperditia scotoburdigalensis is abun-
dant ; and this Leperditia in other localities has sometimes
marine companions. One species, Carbonia subula, is com-
monly accompanied by Myalina modioliformis ?, Brown,
which is a very common fossil in the lower portion of the
Calciferous Sandstone series, and repeatedly occurs with
marine fossils, such as species of Aainus, Aviculopecten,
* In the Trias of Germany Lingula is associated with Estherie of
brackish-water habitat. See ‘ Monogr. Fossil Estheriz, Pal. Soc. 1863,
BP: 48, 49.
Paleozoic Bivalved Entomostraca. 39
Murchisonia, Bellerophon, and Orthoceras. 'Thus in some
few instances we find Carbonie associated with fossils that
are either estuarine or marine, or have decided marine affini-
nies. In the majority of cases they are found with fossils
whose natural habitats we do notknow. This isthe substance
of our present knowledge on the question of the physical con-
ditions belonging to deposits containing the above-described
species.

III.—On a small Collection of Arachnida from the Island
of Johanna, with Note on a Homopterous Insect from the same
Locality. By Artuur G. Butter, F.L.S., F.Z.S., &e.
[Plate I.]
In the year 1877 Mr. C. W. Bewsher sent to the British
Museum a series of Arthropoda collected by himself in the
island of Johanna, Comoro group.
Of the insects under my immediate charge the Hemiptera
Homoptera were alone represented, by an apparently new
species of Phymatostetha, Stal. Unfortunately the example
was sent over in spirits of wine, and is so discoloured and
shrivelled as to render it impossible to characterize it with
certainty.
The Arachnida are represented by seven species of Ara-
neidea, five of which appear to be distinct from any thing
hitherto described ; they exhibit a strongly marked Mascarene
character: the two most interesting forms in the collection
are a new species of Spermophora (Pholcide) and a probably
new species of Pasithea.
The following is a list of the species :—
1. Scytodes amarantea.
Scytodes amarantea, Vinson, Aran. de la Réunion, Maurice et Mada-
gascar, p. 11, pl. 1. fig. 2 (1863).
The single specimen sent is unfortunately destitute of abdo-
men. ‘This fact, taken in conjunction with the long legs of
the species (the femora of which are distinctly rugulose), gives
it so completely the facies of a Phalangid, that until I had
subjected it toa careful examination I was completely puzzled
as to what genus it belonged to.
2. Pasithea foliifera, n. sp. (PI. I. fig. 1.)
Cephalothorax fulvous, marked with black dots and lateral
divergent lines, as in P. Lucasii; eyes black; legs fulvous,
rather thickly studded with long black spines, but not banded
with black ; abdomen bright sap-green, the whole central area
on the upper surface occupied by a broad, central, longitudinal
slightly darker green band, of a leaf-like form, bordered and
intersected with white; ventral surface with pale central area
bounded by two slightly divergent curved white stripes.
Structure similar to that of P. Lucasi’; relative length of
legs 1, 2, 4,35; length of cephalothorax and abdomen together
14 millims.
It is just possible that this may be a remarkable variety of
42 _ Mr. A. G. Butler on a Collection of
P. Lucasii (Sphasus Lucasti, Vinson, Aran. des iles de la
Réun., Maur. et Madag. pl. xiii. fig. 3) ; but the differences in
the coloration of the abdomen and legs are so well marked,
that it seems probable that it is distinct.
3. Attus Bewsheri, n. sp. (Pl. I. fig. 2.)
&. Cephalothorax shining blackish piceous; a transverse
subcruciform marking just beyond the middle; three unequal
oblique white lines (only visible when the spider is dry) just
behind the posterior lateral pairs of eyes; abdomen brassy
brown, crossed in the centre and towards the posterior extre-
mity by two slightly arched white lines interrupted in the
middle; two white spots close to the posterior margin ; legs
piceous, with the terminal tarsal joints fulvous; metatarsi of
posterior pair of legs indistinctly banded with fulvous ; palpi
piceous, clothed with silky whitish hairs, terminal joint ful-
vous below; falces piceous ; pectoral shield and coxee fulvous ;
venter grey.
Cephalothorax square to the middle, thence slightly and
gradually contracted, and with its posterior margin convex ;
superior surface smooth, its highest point being in the centre,
which is bounded by the posterior lateral oculiferous tubercles ;
on each side of this central ridge the surface is oblique ;
abdomen subcylindrical, truncated at each end, slightly wider
in front than behind ; relative size of eyes as follows—ante-
rior central, anterior lateral, posterior lateral, intermediate
lateral, the a c* pair being about six times the size of the
al pair, the ¢/ being situated at about the centre of the
interval between the two other lateral pairs; relative length
of legs 1, 2, 4, 3; length of cephalothorax and abdomen
6 millims.
4, Attus Johanne, n. sp. (PI. I. fig. 3.)
¢ ¢. Cephalothorax blackish piceous, dull, crossed behind
the middle by a bismuate fulvous band (obscured by white
pile when dry) ; the lateral margins, borders of anterior oculi-
ferous tubercles, and a spot on the caput white; abdomen
blackish, with the margins and an ornamental longitudinal
sceptre-like central stripe white ; legs and palpi piceous, banded
with white; under surface of terminal joint of palpi, coxal
joints of legs, and pectoral shield fulvous ; venter whitish, with
central and lateral longitudinal blackish lines.
Cephalothorax inverted-bell-shaped, its superior surface

flattened in front and shelving behind; abdomen subcylin-
drical, narrower behind than in front, with truncated anterior
margin ; relative size and position of eyes as in the preceding
species, briefly expressed as follows—a c 6, al=p 11,711;
relative length of legs 1, 3, 2, 4, but the three posterior pairs
differing very slightly in length ; cephalothorax and abdomen
together 7 millims.
This species seems to be intermediate in character between
A. baptizatus of Rodriguez and A. musezvorus of Réunion and
Mauritius; it is, however, unquestionably nearest to the
latter.
5. Attus anjuanus,n. sp. (Pl. I. fig. 4.)
¢. Cephalothorax piceous (when dry of a golden bronzy
colour), crossed behind the middle by a bisinuated castaneous
belt, behind which the coloration is paler than on the caput;
abdomen whity brown, with a longitudinal arched black stripe
on each side ; anterior border black-speckled ; spinners black-
ish; legs and palpi castaneous, clothed with white hairs;
falces piceous ; legs below and pectoral shield fulvous; venter
whitish.
Cephalothorax rather elongated, inverted-bell-shaped, flat-
tened in front and obliquely arched from behind the posterior
oculiferous tubercles, the latter placed at anterior third; abdo-
men ovate, with convex anterior margin, posterior margin
acuminate ; relative size of eyes, ac 6,al/=pl1,7¢l4; rela-
tive length of legs 1, 3, 2,4; cephalothorax and abdomen
together 8 millims.
Apparently allied to A. africanus of Réunion.
6. Spermophora comoroensis, n. sp. (Pl. I. fig. 5.)
Fulvous, with whitish abdomen ; falces below reddish cas-
taneous.
Cephalothorax inverted-heart-shaped, posterior margins of
the caput indicated by a depressed Y-shaped line, from which
a central depressed longitudinal line runs to the posterior
margin; abdomen ovoid; legs somewhat sparsely but regu-
larly covered with minute black granular dots; tarsi clothed
with short setee ; palpi setose; pectoral shield elongate scuti-
form ; eyes six in number, about equal in size, placed in pairs ;
the anterior pair placed in the centre of the anterior portion
of the caput, the lateral pairs at about the same distance from
the anterior pair as is covered by the two eyes themselves, and
placed obliquely; male palpus with the fourth joint barrel-
shaped, much larger than the three preceding it, terminating
in a bulb-like joint fringed externally with stiff bristles, and
44 Mr. W. J. Sollas on a new
bearing on its inner surface the seminal organ, which is also
bulb-shaped and tapers above into a long spine-like corneous
process; relative length of legs 2, 4, 1, 3; cephalothorax and
abdomen together, of ¢ 7 millims., of 9 8 millims.
I have to thank the Rev. O. P. Cambridge for referring me
to the genus of this species.
7. Gasteracantha madagascariensis ?, var.
Gasteracantha madagascariensis, Vinson, Aran. de la Réunion, Maurice
et Madagascar, p. 242, pl. ix. fig. 6 (1863).
In coloration the example sent agrees far better with G.
mauritia of Walckenaer, the cephalothorax and femora being
reddish castaneous, the tibia and tarsi black, the abdomen
above (in the spirit-example sent) buff-yellow, with black
spines and depressed spots (“ sigilla,’’ Cambr.), below black
spotted with yellow. The Rev. O. P. Cambridge thinks it
more probably a variety of G. madagascariensis ; and if this
be so, I see no reason why the latter should not be conspecific
with G. mauritia, since the difference of form, so far as I can
judge, seems to be very slight between these two spiders.
As regards the strange modification of pattern which must
have taken place if this be in truth a pale variety of G. mada-
gascariensis, I may mention that, so far as can be determined
from dried specimens, G. jlavomaculata seems to show a ten-
dency towards a similar modification.

face, areolate on the upper, growing proliferously upwards
into simple stem-like processes (s) and a thin wide flabellate
expansion (f). The latter, which is seated on a short stout
stalk, is formed apparently by the union of a number of simple
stems, which, fusing together basally, give rise to the stalk,
and then, diverging and branching radiately upwards and out-
wards, produce the fan-like plate, on which their course is
marked by radiating ridges costating both surfaces of the plate,
while the lines along which they unite are indicated by radia-
ting furrows left between the ridges. These furrows are fre-
quently bridged over by irregular transverse connexions, and
thus becomeconverted into series of deeper or shallower irregular
pits. Two open window-like spaces (f) perforating the midst of
the plate are due to the failure of the component ribs in these
places to unite. The lower half of the incrusting base and the
central two thirds of the stems and ribs grey in colour and dense
and compact in texture ; succeeded by an irregularly cavernous,
sulphur-yellow, intermediate layer, which supports a thin
drab dermal membrane, through which, in places, a number
of large pointed spicules project, rendering the surface hirsute
(Pl. VI. fig. 2).
Skeleton. The hard parts are those of the axis or base, of
the intermediate and dermal layers, and of the sarcode.
Axial spicules with a smooth cylindrical shaft, termi-
nated at each end by a spherical microspined inflation,
0-0075 inch long, 0°0005 inch diameter (Pl. VI. fig. 4) ;
confusedly entangled together in a felt-like manner (Pl. VI.
fig. 2).
SS eiediake spicules of two kinds :—(i.) a long, robust,
curved, conical acuate, sharply pointed at one end and gene-
rally spherically inflated at the other, inflation usually smooth
(Pl. VI. fig. 3), sometimes minutely spined (Pl. VII. fig.
8); length 0°041 inch, diameter of shaft 00018 inch, of head
0-002 inch; collected in short columns, projecting at right
angles from the axial core, in the external layer of which
the inflated ends of some of the spicules are imbedded (PI. VI.
fig. 2); (il.) a smaller curved, spined acuate, 0:01 inch
long, 0°001 inch broad, pointed at one end, inflated spheri-
cally at the other, spines on inflation blunt (PI. VII. fig. 16),
or pointed, with the points directed from the head to the
other extremity of the spicule (Pl. VII. fig. 17); spines of
the shaft commencing about the middle of its length, and
extending within a short distance of its point, conical, re-
curved, numerous; inflated heads of the spicules imbedded
in the axial cord or in the penicillate columns of larger
acuates, pointed ends projecting echinately (Pl. VL. fig. 2).
Dermal simple, straight, conical acuates, rounded obtusely
46 Mr. W. J. Sollas on a new
at one end, seldom inflated, sharply pointed at the other
(Pl. VL. fig. 6 and Pl. VII. fig. 28) ; rounded end smooth,some-
times sparsely microspined (PI. VII. fig. 27), 0°015 inch long,
0:0004 inch broad ; arranged matted together felt-like, sup-
ported on the ends of the large intermediate acuates, about
which they sometimes accumulate in a tent-like projection
(Pl. VI. fig. 2).
Sarcode. Flesh-spicules of two kinds, both very minute,
not exceeding 0°0003 inch in length—one a tricurvate (Pl. VI.
fig. 7 and Pl. VII. fig. 19, 4), the other an equianchorate, with
a straight or curved shaft and three recurved minute arms at
each end (PI. VI. fig. 7 and Pl. VII. fig. 19, a), dispersed
through bright yellow sarcode.

Coll. Bristol Museum, presented by John Thwaites, Esq
Obs. The single specimen of this sponge is in a very per-
fect state of preservation, having been well dried without
losing its sarcode. How it was obtained by Mr. Thwaites,
and from what depth in the sea, there is nothing to show ;_ but
its occurrence on the western side of Africa so far south as
15° from the equator is interesting, since both Oscar Schmidt’s*
species of Plocamia came from the other side of the Atlantic
and north of the equator, viz. one from Florida at a depth of
195 fathoms (P. gymnazusa), and the other from Cuba at a
depth of 270 fathoms (P. clopetaria).
It is clear from O. Schmidt’s definition of the genus Plo-
camia that our form must be referred to it; and this reference
is made all the more certain by the close general agreement
between P. plena and the two previously described species,
both in structure and spiculation. In P. gymnazusa, O. 8.,
there is a large acuate in the intermediate layer, like that of
P. plena; but our spined echinating acuate is represented by
a smooth form without spines; the needle-like spicules of the
dermis appear to be present in both, as well as the dumbbell-
headed, handle-like spicules of the axis. O. Schmidt does
not make any mention of flesh-spicules; but as in P. plena
these are very minute, it is just possible that, if present in the
other forms, they may have escaped his attention.
Putting these on one side, then, the distinction between P.
gymnazusa and P. plena, so far as it can be learned from de-
scription merely, appears to lie chiefly in the different form of
the echinating acuates :—in the latter a richly spined, straight,
or curved acuate with an inflated head ; in the former a smooth,
* Grundziige einer Spongienfauna des atlantischen Gebietes, pp. 62,
80, Taf. iv. figs. 17, 18.
Species of Echinonematous Sponge. 47
abruptly bent acuate, sharply pointed at one end and merely
rounded off at the other. In P. clopetaria, O. 8., a fat
clumsy tuberculated spicule is said to be characteristic, and
travesties rather than represents our echinating acuate.
As regards the affinities of the genus, O. Schmidt considers
it related on one hand to the Suberites, and on the other
to the genus Clathria. ‘That it is a true echinonematous
sponge (¢. e. allied to Clathria) there is no doubt; and cer-
tainly the spicules of the axial column and lower part of the
base are arranged in a very suberitic fashion. The scopi-
form bundles of acuates in the intermediate layer remind one
of Microciona; and if one added to the membranous base of
the latter a layer of felted spicules, the resemblance would
become almost complete, especially as Myzilla, which in at
least some of its species is identical with IMvcrociona, fre-
quently grows upwards into stalked processes, which appear
to resemble those of P. plena.
In the relation of the scopiform bundles of spicules to the
axial columns of the sponge, Plocamia shows some similarity
to Dictyocylindrus ramosus, Bwk.; but the latter has not the
spicular dermal layer which occurs in the former. In Phakellia
the dermal layer is present, but the scopiform bundles are re-
placed by long plumose fibres. Thus the affinities of the sponge
are all with Kchinonematous forms; and it should apparently
be referred to the family Ectyonide, where it will form a
group by itself, viz. the Plocamianina, with the following defi-
nition :—Sponge growing proliterously upwards from an
incrusting base ; skeleton consisting of axial columns of dumb-
bell-headed spicules supporting scopiform bundles of large
acuates, which, as well as the axial columns, are echinated by
smaller acuates of another form, the exterior provided with a
dermal spicular covering, and the sarcode containing very
minute flesh-spicules.

It is worthy of notice that no horny material is discoverable
48 Mr. W. J. Sollas on a new
in these sponges. O. Schmidt says that none is present in
the two species he had examined ; and to determine whether
there might not be some in mine I mounted a few slices of
the sponge in glycerine jelly, which makes the siliceous
spicules almost invisible, and so brings into greater distinct-
ness the other parts. The sarcode was thus rendered very
visible ; but no kerataceous material could be detected. The
sarcode, we may mention, soon parted with some of its intense
yellow colouring-matter to the surrounding medium, which thus
at first assumed a yellow tint that has since almost entirely
disappeared. By the absence of horny matter in it Plocamia
does not quite meet the requirements of Carter’s definition of
his order; but this is a small point of difference ; and from the
examination of a large number of Echinonematous sponges 1
am inclined to think that the presence or absence of horny
matter is not of ordinal value, or, more properly, that the
passage from a spiculose horny fibre, whether echinated or
not, to a wholly spicular not horny fibre is so gradual that it
is impossible to draw a hard-and-fast line between the two,
and that, just as a Renierid may be regarded as a Holorha-
phidote development of a Chalinid, so there may be sponges
among the Echinonemata which may be regarded as Holo-
rhaphidote developments of the Ectyonide ; and such I believe
is the nature of Plocamia for one, not to mention others.
If we adopt a monophyletic origin for the various forms of
spicules found in Plocamia and other sponges, we shall natu-
rally be led to look for some evidence of this amidst the wide
variations which the spicular forms assume ; and such evidence
is, I think, to be readily found. In the first place, leaving
out of account the flesh-spicules, of which we know too little
at present, and which may have a separate origin to the others,
one observes a- close family likeness in all the forms of
spicules to be found in Plocamia: thus, though they differ
considerably in proportion, they all present a conical or cylin-
drical form, without any tendency to become fusiform, they
all exhibit a tendency to acquire spines, and they all vary in
the same kind of way. ‘The dermal spicules, for instance,
often acquire an inflated head, and, though usually very
straight, sometimes become slightly curved; on the other
hand, the large intermediate acuates sometimes lose their
terminal inflation and so present merely a rounded-off end,
and, though usually curved, they sometimes become straight ;
while in both dermal and intermediate acuates the head often
becomes more or less spined. The only constant difference
which distinguishes these two forms thus lies only in size and
proportion ; and even in the latter character variation occurs,
Species of Echinonematous Sponge. 49
the intermediate acuates becoming thinner and the dermal
acuates thicker, and so approaching the one to the other. Hence
I see no difficulty in believing that the spicule-cell of the larger
acuate is a direct descendant of that of the dermal spicule.
Again, the dermal spicule sometimes becomes rounded off at
both ends, and in one instance was observed with an inflation
at each end, each inflation being sparsely microspined
(Pl. VII. fig. 20); on the other hand, the dumbbell-like
axial spicule loses one of its inflations, retaining the other, so
that at one end it possesses a spherical head, and at the other
is merely rounded off (Pl. VII. fig. 26), or terminated some-
times by a blunt mucrone (PI. VII. fig. 25), which, however,
still retains its microtuberculation, though the tubercles ex-
hibit a tendency to acquire the characters of small spines;
again, the axial spicule varies much in proportional length,
being sometimes very short and stumpy, like Pl. VII. fig. 21,
and at others elongating and narrowing till one has the attenu-
ated form, Pl. VII. fig. 22, very similar in proportion to one
of the dermal spicules. ‘Thus the passage of a dermal spicule
into one of the dumbbell-like forms is by no means incon-
celivable. As regards the spined echinating spicules, these
exhibit as many variations as the others ; the extent to which
the pointed end is spined is very inconstant, some forms re-
maining almost smooth (Pl. VII. fig. 13, for imstance), in
which case they closely resemble the young spinose-headed
forms (Pl. VII. fig. 12) of the intermediate acuates, from
which they might easily have been derived. Our theory of
the relationship between these various spicules may be ex-
pressed in the following diagram :—
Adult smooth acuate
(fig. 3).
Young form of —<— Dermal spicule —>- Axial spicule
acuate (fig. 28). (fig. 4).
(fig. 12). :
Adult spinose acuate
(fig. 5).
Of other variations displayed by the spicules one may
notice the tendency, very frequently displayed by the large
acuates, to exchange the pointed for a rounded extremity,
thus passing irito the cylindrical spicule, Pl. VII. fig. 9; and
this may be combined with a general stunting m linear
growth, which leads to such forms as figs. 10, 11, Pvt
and might, if carried far enough, give us a truly globular
Ann. & Mag. N. Hist. Ser. 5. Vol. iv. 4
50 Mr. W. J. Sollas on a new
form as the end of the series. It would not do, however, to
regard such a globular spicule as in any way resembling the
balls of the Geodide ; for in the latter the growth is purely
radiate, in the former as purely concentric ; one is an over-
grown stellate spicule, the other an aborted acuate; and the
difference between them is made very manifest by treatment
with boiling alkali, the Geodia-globule dissolvmg rapidly
from the centre outwards, the Plocaméa-cylinder obdurately
resisting all solution and never admitting the potash to its
interior.
Vinally, the acuates sometimes become bent upon them-
selves, to the extent of 90° or much more (Pl. VII. fig. 18) ;
and as bending usually foreshadows branching, so we some-
times find a spicule putting forth a spine-like branch near its
extremity, into which enters correspondingly a branch from
the axial canal; such a bifurcation of the end of one of these
acuates carries us much nearer the trifid spicules of the
Pachastrellidee and Pachytragide than the bi- and trifurca-
tion in the echinating spicules of Plectronella, since in the
latter it is the head end which is so divided, while here, as
in the groups just mentioned, it is the pointed end of the
spicule.
In conclusion we have to consider the behaviour of the
spicules when treated with boiling solution of potash. The
spined acuates under these circumstances readily dissolved
both within and without, in just the same manner as uniaxial
spicules usually do; and I was able to make quite certain
that no branches were supplied to the spines by the axial
canal; the spines are merely local thickenings of the exterior
of the spicule, not aborted branches as is the case with Plec-
tronella.
Kchinating acuate after treatment with boiling potash (x 435),
The dumbbell spicules and the large acuates with both ends
rounded seldom underwent internal solution, unless they had
been broken across so as to make the axial canal accessible.
Solution of the exterior proceeded rapidly, coat after coat of
the acerates being removed, and, indeed, of the dumbbell forms
as well, exposing the successive forms through which they
had passed durmg their growth; and it is worth mentioning
Species of Echinonematous Sponge. 51
that the forms so revealed were always similar to that of the
spicule from which they were derived, a conical acuate always
remaining a conical acuate, and a stunted cylindrical one
always remaining stunted and cylindrical; and thus Bower-
bank’s notion that the latter are young forms of the former,
and would become pointed and conical with growth, is refuted;
the cylindric are aborted, not immature forms of the acuates.
The statement that residual acuates are of the same or similar
form to the original ones may appear difficult to verify, since
when the outer coat has been removed there is nothing
left to show what the form originally was; and since the solu-
tion takes place while the spicules are being boiled, one can-
not witness the removal of a coating. That is true: but it is
a remarkable fact that solution does not wholly remove the
outer coat; in other words, the solution is partial only; for
after the potash has dissolved away the silica of one of the
envelopes there remains behind a less soluble residue, which
has the appearance of a delicate, soft, membranous film, and
which retains very closely the original form of the envelope
from which it was derived. Thus in fig. 2 we have a sketch

folded, delicate, almost invisible substance (f) the solid,

What, then, is the nature of this residual substance, which,

though presenting a strangely organic appearance, is yet able
to resist the effects of boiling solution of alkali? From the
fact that some small pieces of cork, which were accidentally
present with the boiling spicules, had not suffered any marked
decomposition, nothing more than a separation, to a certain
extent, of their cells, it occurred to me that it might be a form
of cellulose, which is known to occur now in various groups
of animals, and which would not be an unlikely accompani-
ment to the green colouring-matter (probably chlorophyll)
which characterizes some kinds of sponges. On testing with
Schulze’s solution, however, the membrane was not coloured,
while the associated fragments of cork became stained of a deep
violet; on exposing to a high temperature it appeared to
become carbonized ; it did not affect polarized light. These
are the only observations I have made with regard to this
substance at present; my next step will be to submit some
sponge-spicules to organic analysis; till then I regard the
composition of their organic foundation as an open question.
The heads of the axial spicules appear to suffer far more
from solution than their shafts, the whole interior of a head
being sometimes eaten out without the shaft showing any
evident signs of solution. Can this in any way be connected
with the micro-tuberculation of the heads ?
Fig. 4.
Two of the double-headed axial spicules after boiling with potash
(x 455). Shaded parts indicate the cavities which have been
excavated by solution.
From the cavity thus excavated in the head, the potash
sometimes finds its way into the axial canal; but quite as
often it dissolves a path for itself outside the site of the axial
canal down each side of the spicule.

Part III. RESTORATION OF LErIoDON ANCEPS.
In the section on Mosasauroids, in the “ Report on British
54. Prof, R. Owen on the Occurrence
Fossil Reptiles ” for 1841*, a genus Levodon was defined on a
modification of mosasauroid teeth in a fragment of jaw dis-
covered in a Cretaceous formation in Norfolk, and figured in
plate Ixxii. figs. 1, 2, of my ‘ Odontography.’
Certain vertebre from the Greensand of New Jersey, North
America, submitted to my examination by Prof. Henry Rogers,
in 1849+, presented mosasauroid characters, but differed from
those which had been referred by Cuviert and Goldfuss§ to
the type genus Mosasaurus in a degree which led me to re-
mark that “ they might belong to the genus Ledodon ;” but
I, provisionally, described and figured them under the name
of “ Macrosaurus levis.” Similar vertebrae were subse-
quently discovered by Prof. Emmons in Cretaceous deposits
of North Carolina, and were referred by him to the genus
Macrosaurus ||.
Dr. Joseph Leidy, in his excellent work ‘ On the Cretace-
ous Reptiles of the United States,’ 4to, 1864, notices mosa-
sauroid teeth from other localities in the United States, several
of which he states to “ correspond in all anatomical characters
with the teeth described by Prof. Owen as characteristic of a
distinct genus, to which he has given the name of Letodon”’ 7] ;
but in the figures of his plate xi. those teeth are referred to
Mosasaurus.
Prof. E. D. Cope, in his richly illustrated volume on the
Vertebrata of the Cretaceous Formations of the West,- de-
scribes and figures specimens which enabled him to show that
the vertebrae of Macrosaurus were actually those of Letodon
levis, and also to define other species of that mosasauroid
genus** obtained from the ‘ Kansas chalk.”
Finally, in the ‘ Transactions of the Kansas Academy of
Science’ for 1877-8, vol. vi., Prof. F. H. Snow describes and
figures characteristic portions of an almost entire skeleton of
a Leiodon which he had the good fortune to expose in the

“yellow limestones belonging to the Niobrara group of the
Cretaceous Formations ””*.
From these American materials a restoration of the Letodon
modification of the Mosasauroid Lacertians may be under-
taken. Of the skull I have little to add to the description
given in my paper “On the Rank and Affinities of the
Mosasauroids’’t. The edentulous production of the pre-
maxillary (Pl. VIII. fig. 1, a) beyond the alveoli of the
*=* incisors may be noticed as suggestive of a rudiment or
beginning of the Ziphioid modification of the cetaceous cra-
nium. The mandible is slender, with a low coronoid process
and slightly produced angle. A specimen has been found
26 inches in length f.
The vertebral column of Letodon anceps (Pl. VIII. fig. 1)
-exhibits the range of modification in its several regions
characteristic of these great extinct ‘ Lacertia Natantia’§,
and contrasting with the comparative uniformity of the ver-
tebree in Python and other Ophidia.
The atlas (ib. fig. 2) consists, as in lizards||, of a pair of
neurapophyses, 7, and a detached hemapophysis, 4, simula-
ting a centrum{]. The transverse exceeds the vertical dia-
meter, although the latter is extended by a short obtuse
hypapophysial spine, y, less developed than in Mosasaurus**.
Hach neurapophysis presents a large subconcave facet for
articulating with part of the occipital condyle ; a rudimental
diapophysis projects from the outer side.
The axis (ib. fig. 3) consists of a long body, including the
proper centrum of the atlas, ca, coalesced with that of the
axis,c x. The latter develops a hypapophysis, y, to which
is articulated a short hemapophysis, 2. A compressed ver-
tical ridge-like process (par-diapophysis, @) extends from each
side of the centrum; it may be for the support of a rudimental
cervical rib.
A few of the succeeding vertebrae are characterized by both
diapophysis (ib. fig. 4, @) and hypapophysis, y—the latter
with a rough articular surface fer ligamentous attachment of a

short imperforate hemapophysis, 4. The series of these
hemapophyses are homologues of those described by Sir
Philip de M. Grey Egerton under the name of “ subver-
tebral wedge-bones”’ in Jchthyosaurus*. 'They are present in
similar intervertebral position in Amblyrhynchust, where they
are five or six in number. They are represented by con-
fluent pieces in Cyclodust. But the presence of hypapo-
physes for their support distinguishes the Mosasauroid from
other families of Lacertilia as well as from both Ichthyo- and
Sauropterygia.
The diapophysis of the third cervical supports a rib; and a
similar costigerous process§ is present in the dorsal vertebrae.
This series may be conveniently, though artificially, defined
by the suppression of the hypapophysis. The zygapophyses
(figs. 5 and 6, 2, 2’) disappear in the posterior dorsals as in
fig. 7. The diminution in vertical and increase in longi-
tudinal extent, together with its descent in position from the
side of the centrum, reduce the “ transverse process”’ to a
“ parapophysis,” p, fig. 8, which characterizes the lumbar
vertebre. This change is attended with a modification of the
shape of the centrum, the transverse section of which becomes
triangular with the base downward, instead of the elliptic
shape shown in the vertebre from the antecedent part of the
column. ‘There is no sacrum by ankylosis: a single ver-
tebra supports a pair of small rib-like, feebly curved, iliac
bones (ib. fig. 1,/), with a slightly expanded, distal, bifaceted,
syndesmosal surface, the larger division for the ischium. The
pubics, wv, have a smaller syndesmosal terminal expansion, are
slender and nearly straight. The ischia (m) are broader, have
a short posterior process, offer proximally a syndesmosal sur-
face divided between the ilium and the femur, and have a
distal surface for a symphysis with their fellow, completing
the inverted arch below.
The anterior caudal vertebrae add to the parapophyses
(fig. 9, p) a pair of hypapophyses, y, to which is articulated
a hemal arch formed by the apical confluence of a pair of
heemapophyses, h, from which confluence extends obliquely
backward a hemal spine, # s, rivalling or surpassing the
neural one, »s, in length. The parapophysis gradually
shortens and disappears at about the anterior third of the tail
(fig. 10), which thereafter shows its natatory compression and

vertical extension attended with piscine confluence of the

No Mosasauroid has hitherto been discovered so entire and
undisturbed, or exhumed with such exact care, as to yield a
precise numerical vertebral formula. LKven in the skeleton
of the Letodon described by Prof. Snow, “ only two of the
twenty vertebree, which were scattered over the slab in all
positions, remained united ”’*.
The nearest approaches to the true number in the genus
Mosasaurus I believe to have been made by Cuvier (who assigns
133) and by Goldfuss (157). Of Letodon I estimate, pro-
visionally, from the various data at command, the follow-

The vertebre of Ledodon are devoid of the accessory zygan-

In entering upon the description of the British Fossil Rep-

to the parts and processes of the vertebrae cumbrous, if at all
applicable to the homologous parts in those of the lower (especi-
ally the cold-blooded) Vertebrates, some apophyses in which
had no homologues in the human vertebra. I therefore pro-
posed a “‘ Nomenclature,” substituting ‘‘names” for “phrases,”
and devised names for parts which previously had none.

58 Prof. R. Owen on the Occurrence
The general adaptive characters of the Mosasaurian verte-
bre relate to aquatic life; and in the category (type 7)
in which the zygapophyses ‘disappear, not to return, there is
a significant indication of a tendency towards the Cetacea; in
a great extent of the caudal series (type 11) a piscine charac-
ter prevails. Both these modifications are engrafted on, or
associated with, the lacertian type of the proccelian vertebra.
The movements of this gigantic reptile among the sea-waves,
mainly executed by the long and flexile vertebral column,
were guided or modified by the action of both pectoral and
pelvic fins: the retention of both pairs is more piscine than
cetacean ; or, we may say, the common vertebrate number of
limbs, in Mosasaurs as in Ichthyosaurs, has not been departed
from, as in some later and more modified forms of warm-
blooded marine Vertebrates. Are the pelvic and femoral
rudiments, which are concealed beneath the skin in modern
whales, the remnants of the ventral fins of the cold-blooded
marine air-breather? or are they remnants of the hind legs
of a warm-blooded, ancestral, shore-haunting quadruped ?
Such pleasant speculations as a solace to the work of acqui-
sition of positive facts may be condoned.
The framework of the pectoral fin was first restored by
Prof. Marsh *, in the American Mosasauroid which he ealls
Lestosaurus simus (Platecarpus, Cope) : the Lacertian type of
this framework is illustrated, in comparison with the Cetacean
and Enaliosaurian types, in the undercited work f. In the
large proportion of a Leiodon discovered by Prof. Snow of the
Kansas University, in the “ yellow limestones along the
Hackbury Creek, in Yove County, Kansas,” the framework
of the pectoral fin was found “‘ lying underneath the ribs and
vertebree, with the bones in natural position.” Fig. 13, Pl.
VIIL., is a reduced copy of the Professor’s figure of this fin f.
Assuming the accuracy of the arrangement of the bones, the
first (innermost or radial) digit (1) is the longest, and includes
a metacarpal (m) and eleven phalanges ; the second digit (11)
has the same number of phalanges and nearly the same length ;
the third (111) has nine phalanges; the fourth (1v) shows seven,
but one or two small terminal bones seem to be wanting ; the
fifth, outermost or ulnar, digit (v) has evidently been the
shortest, and retains but five phalanges. In the general shape of

the fin, decreasing in length from the radial, 54, to the ulnar, 55,
side, the fin of Leiodon resembles more that of the Cetacean®
than does the fin of Lestosawrus, but with the marked diffe-
rence of the first digit being the shortest in Cetacea and the
longest in the present genus of Mosasauria.
‘The most instructive addition to the anatomy of this extinct
family of marine Saurians is the degree in which the dermal
skeleton is preserved in the Kansas example of Letodon f.
Prof. Marsh had referred certain dermal scutes to Mosa-
sauroid reptiles, and conceived them “ to be mainly from the
lower part of the neck.” “In the genus Liodon,” he adds,
*‘ the scutes are also imbricate, and somewhat similar to those
above described ’’$ (in the genus Hdestosaurus). But Prof.
Snow has brought to light an extensive series of such os-
seous scales, indicative of a more general dermal scutation.
Fig. 14, Pl. VIIL., is a copy of a portion of this armour
from one of the flanks of the Levodon, of the natural size.
In no known Ophidian are the scales formed in any pro-
portion by bone; the purely epidermal tissue of their exu-
vial coat’ would be wholly dissolved in remains from a
Cretaceous matrix, or, indeed, of one of more recent date.
The Sheppey and other Eocene serpents are represented
only by the parts of their endoskeleton; and so large a
proportion of this has been found in natural articulation
as to lend ground for expectation that the dermal scales
would have been preserved if, as in lizards, they had included
petrifiable parts§. In the existing members of the Lacertian
order bone is developed at the base of the scale in several
genera, e.g. Trachysaurus, Tribolonotus, Ophisaurus, &e.
And if the curious fossils called ‘ granicones,”’ found in the
“‘ Feather-bed ”’ shales of the Middle Purbecks, have been
rightly interpreted ||, they likewise exemplify the osseous sup-
ports of the scales of an extinct lizard (Nuthetes destructor)—
and, by virtue of their tissue, have been susceptible of fossili-
zation; and testify to the dermal character of that species.

teeth, attributed to the genus Ledodon and exemplified by
transverse sections in fig. 15, Pl. VIII., has been found con-
stant and characteristic of those teeth in the species of the
genus noted as from the various localities in Leidy’s ‘ Mo-
nograph on the Cretaceous Reptiles of the United States,’
and represented in pls. ix.-xi., and in the woodcuts of
pp. 58-69. The subject of Leidy’s cut no. 18, and of fig. 7,
pl. ix., from Monmouth County, New Jersey, is noted as
corresponding in all its anatomical characters with those of
Leiodon (p. 62).
The Mosasauroid or family characters of the teeth are
strictly retained. ‘The crown, composed of hard dentine with
a thin coat of enamel, is supported by, and as it were wedged
into a basis (fang or root) of the modified osteine called
“cement.” This is much thicker than the crown, and pre-
sents a rounded or full elliptical transverse section, whatever
be the shape of the crown (compare the outline @ (root) with
b (crown) of a tooth of Letodon, fig. 15, Pl. VILI.).
The root, when first formed, is implanted in a distinct
socket, and the “ thecodont ” type of dentition is manifested.
But this is a transitory condition; the cement becoming con-
fluent with the bone of the socket, and, partially rising above
the alveolar border of the jaw, the tooth then exhibits the
“‘ acrodont” type. But amuch larger proportion of the orginal
and independent tooth can be traced in the substance of the jaw
than is the case in the existing acrodont Lacertilia. ‘The pulp-
cavity remains in the basal half of the crown, and descends a
short way into the cemental fang, where it is closed by a
coarser and more vascular modification of the cement. The
vertical or longitudinal extent of the enamelled crown at its
outer and exposed surface is about one third that of the fang.
The teeth are displaced and succeeded by others, many
times during the life of the individual, as in modern Lacertilia.
At least I have met with no specimens in which a reserve
cavity with a more or less advanced successional tooth has
not existed at the postero-internal side of the implanted base
of the functional tooth*. The germ of a third generation in
the form of the enamelled apex of the crown may be detected
within the pulp-cavity of the second, which is in course of
succeeding and displacing the first or fully formed tooth f.
The nearest resemblance to the Mosasauroid type of tooth
is now presented by certain Cetacea, as, e. y., the Cachalots {,
Platanists$, and more especially by the Ziphioids, nm which

Sponge simple or branched, cylindrical, clavate or pyriform,

the base. ‘Theskeleton consists of coarse anastomosing fibres,
which spread out like lamellae at the surface, except at the
vertex, become fused together, and form a smooth, dense
dermal layer, in which are situate round or misshapen, some-
times margined apertures, which are connected with shallow
depressions. In the same way the wall of the stomachal cavity
also consists of a smooth layer, which is only pierced by pore-
like openings.
The canal-system is indistinctly developed in consequence
of the large-meshed texture of the skeleton; the water pro-
bably passed through the large ostia of the surface into the
sponge-body, circulated between the large spicular fibres, and
reached the stomachal cavity through the above-mentioned
pores. . In cut specimens no canals appear either in longitu-
dinal or in transverse sections.
Of this genus a species from the Great Oolite of Caen was
* A few days ago two fragments of rock belonging to the older Creta-
ceous, from Pirot, in Bulgaria, were sent to me by Prof. Toula of Vienna.
They consisted almost entirely of small subcylindrical bodies narrowed
downwards, about 10-15 millims. in length, and 5-4 millims. in thickness.
These evidently organic hollow bodies most resembled the Gyroporelle
of the Trias, but they wanted the characteristic pores and canals of the
latter. It is true that radial canals open into the central cavity, and these
become more oblique downwards, and finally rise from below perpendicu-
larly into the stomachal cavity ; but there is no fibrous texture. On the
other hand, we sometimes observe a few large bacillar spicules, and tri-
and quadriradiate spicules, in the usually homogeneous wall; but their
form cannot be exactly ascertained. If these bodies, which occur in
such quantities, belong, as I suppose, to the Leucones, this family would
consequently commence in the Cretaceous.

described as early as 1821 by Lamouroux, who named it in
honour of M. Eudes-Deslongchamps. Michelin (Ie. pl. lviii.
fig. 8) gives a new and excellent figure of the same species,
but, curiously enough, regards the characteristic smooth epi-
dermis of the surface as a foreign parasitic body, for which
he retains the name of Hudea, whilst its supposed support is
described as Seyphia clavartoides or cymosa.
D’Orbigny restores Michelin’s Hudea cribraria to Lamou-
roux’s species, but applies the name of Hudea to a great number
of cylindrical sponges with well-developed canal-systems.
Fromentel finally, in opposition to all the rules of termino-
logy, retains the name of Hudea for a great part of the forms
referred by D’Orbigny to Lamouroux’s genus, and gives the
typical species (#. clavata, Lamx.,=Hudea cribraria, Mich.)
a new generic name, Hpeudea (or Ependea). Subsequently
Fromentel established a distinct genus Stegendea (more cor-
rectly Stegeudea) for the branched forms.
Pomel, indeed, reverts to Lamouroux’s conception, but esta-
blishes the superfluous genera “/asmeudea and Solenolmic.
By Quenstedt the Upper-Jurassie species were described in
his earlier works as Spongites, but in the ‘ Petrefactenkunde

Several species of Hudea occur in the Alpine Trias; but the
genus has its principal distribution in the Upper Jura. Here
the specimens are frequently silicified, sometimes at the sur-
face, sometimes throughout.

Manon p. p., Miinst., Klipst.
Amorphospongia p. p., D’Orb.
Sponge cylindrical, clavate, sometimes branched, built up
of globular or annular segments, which are indicated exter-
nally by deep constrictions. Surface coarsely porous, the
lower segments sometimes clothed with a smooth, dense
dermal layer. Vertex convex, with the small circular osculum
of a narrow central cavity, which passes through the whole
sponge-body.
The segments internally are occupied by an extremely
loose anastomosing fibrous tissue, which is somewhat con-
densed at the walls. Canal-system wanting.
I have modified Laube’s diagnosis in accordance with a
well-preserved branching specimen from the Seeland Alp,
which in transverse section shows a central cavity, and no-
where exhibits an epitheca. Colospongia unites Hudea with
Verticillites. From the latter the present genus differs by
possessing imperfectly developed transverse floors, and also
by the circumstance that the segments are not hollow inter-
nally, but filled with loose tissue. The only species is from
the Alpine Trias :—

Sponge simple or bushy. Isolated individuals cylindrical
or clavate, frequently with horizontal constrictions at the
surface. Vertex with a circularosculum. The whole sponge-
body built up of thin-walled hollow rings, each of which fits
upon the preceding one in such a manner that the horizontal
or arched cover of the first forms at the same time the floor of
M. K. A. Zittel on Fossil Calcispongie. 65
the following one. These rings are traversed by a vertical
central tube, extending from the osculum to the base. The
wall of the central cavity, the external wall, and the trans-
verse floors are repeatedly perforated and furnished with
canals, which lead into the interior of the hollow segments.
All the walls consist of a tissue of anastomosing calcareous
fibres. In certain species the floors of the hollow rings are
united to each other by fine vertical processes of the skeletal
substance.
The microstructure of the calcareous skeleton is in general
destroyed; so that, when highly magnified, the fibres merely
show a radiate crystalline texture. In a specimen of Verti-
cillites anastomosans, Mant., however, from the Aptian of La
Presta, I have succeeded in demonstrating that the fibres are
composed of usually distinctly triradiate spicules. By this
means the relationship of this genus (which in its general
habit is most intimately connected with Peronella) to the
sponges is established with certainty.
I am acquainted with various species from the Trias and
Lower Cretaceous.

Sponge composed of globular or ovate individuals, irregu-
larly arranged upon one another, often united into nodular
masses, constantly increasing in size according to their age.
Wall of the individual dense, pierced by isolated margined
oscula. This wall encloses a cavity which is very incom-
pletely occupied by a very loose web composed of fine ana-
stomosing’ fibres.
Under the microscope both the wall and the fibrous tissue
in the interior appear solid. As, however, the same constitu-
tion is observed in many true Calcispongiz from St. Cassian,
it may be regarded as a consequence of late alterations.
I place this very peculiar genus with many doubts among
the Calcispongie. Its whole external appearance, and its
constitution of separate, well-defined chambers, rather reminds
one of certain Foraminifera; but the partial filling of the
chambers with a loose-meshed tissue is irreconcilable with
the idea of a Foraminifer.
The structure furnishes no information as to the zoological
position of the genus, which, however, may be best arranged
beside Colospongia and Verticillites.
The only species is from the Trias of St. Cassian :-—

a central circular osculum, the efferent orifice of a narrow tube
traversing the whole sponge. Surface furnished up to the
margin of the vertex. with a.smooth or concentrically wrinkled
dermal layer. No radial or other canals. In longitudinal’
section the fibrous skeleton shows a tendency to become con-
densed parallel to the vertex at regular distances, so as to
produce a faint indication of transverse floors.

cillites. ‘The narrow perforant central cavity and the absence

of segment-formation, although but slight, of the two last-
mentioned genera. The smooth epitheea, which extends up

Simple, or branched by gemmation; individuals cylin-
drical, thick-walled; vertex convex, rarely flat, in the middle
with the narrow circular osculum of the tubular stomachal
cavity, which, retaining nearly the same diameter, traverses
the whole length of the sponge-body to the vicinity of the
base. Incurrent canals wanting. Wall of the stomachal
cavity and surface porous. Outer surface either naked or
coated with a dense concentrically wrinkled epidermis at the
base, and sometimes up to the neighbourhood of the vertex.
The skeleton consists of generally coarse, vermiform, anas-
tomosing fibres, which form a confused tissue. In the irre-
gular-shaped meshes and interstices of this the water circu-
lated, no special canals or ostia being necessary. The pore-
like orifices on the surface and on the wall of the central
canal are merely gaps in the vermiform tissue.
In general the skeleton still consists of carbonate of lime ;
but in certain localities, especially of the Upper Jura, nearly
all the specimens are silicified. In the latter the spicules of
which the fibres consist are never preserved. In calcareous
skeletons, on the contrary, the microstructure may usually
be detected with certainty, although distinctly preserved spi-
cules are rarely observed.
The vermiform fibres appear chiefly to be composed of tri-
radiate (perhaps also quadriradiate) spicules, but simple bacil-
lar spicules are often associated with these in great numbers.
The size and form of the triradiates, and especially the length .
of the individual, sometimes curved arms, vary considerably
in the different species.
This rich genus, which extends from the Trias into the
Upper Cretaceous, may be distinguished easily from the

allied forms by the narrow tubular central cavity of the cylin-
drical body and by the absence of any radial canals. The
forms belonging to it were named by the older writers Scy-
phia, Spongia, or Siphonia; D'Orbigny erroneously united
them with Lamouroux’s genera Hudea and Hippalimus.
Etallon (Etudes pal. sur le Haut-Jura, 1859, p. 142) pro-
posed for a part of the species described by D’Orbigny as
Eudea and Hippalimus the generic name Pareudea, under
which are included the Jurassic forms of the present genus, as
well as several Husiphonelle.
In the same year Fromentel (Introd. p. 31) established the
genera Siphonocelia and Polyceelia, which, in general, repre-
sent Etallon’s Pareudea. The monozoic forms were named
Siphonocelie, the polyzoic Polycelie, and, as the latter name
was already occupied, subsequently Discaelie (Cat. rais. Spon-
git. Neoc. 1861, p. 4). This correction has escaped most
authors; and the name Polyceelia was therefore replaced by
Dendrocelia by Laube, by Celoscyphia* by R. Tate, and by
Pliocelia by Pomel.
A generic separation of the monozoic and polyzoic forms is
quite inadmissible in this genus; for sometimes the same
species makes its appearance as a simple individual and as a
composite stock. Nor does the genus Stenocelia, From.
(Cat. rais. p. 4) seem to me to be any better founded. Fro-
mentel refers to it those D7scaelie in which the individuals are
fused together laterally almost to the vertex, so that nodular
stocks with perforated wart-like elevations are produced.
In his most recent work Quenstedt describes the Jurassic
forms under the generic denominations Spongites, Vermi-
spongia, and Radicispongia, and the Cretaceous ones gene-
rally as Scyphie.
The above-cited genera of Pomel are distinguished partly
by the supposed siliceous or calcareous nature of the skeleton,
partly by the thickness of the anastomosing fibres, and partly
by the external form.
It appears to me not improbable that when we have a
better knowledge of the spicules which compose the skeletal
fibres, a division of the forms united under Peronella into
several genera may be practicable; for that in this respect
very important differences occur, may be seen at once from a
comparison of the spicules of Peronella cylindrica from the
Upper Jurassic, and of P. multidigitata, Mich., from the
* Judging from the figure of Celoscyphia sulcata, Tate (Quart. Journ.
Geol. Soc. xxi. p. 43), I suppose that this species does not belong to the
Calcispongiz, but to the Hexactinellide, and, indeed, in the neighbour-
hood of Polyblastidium, Zitt.

however, presents insuperable obstacles to a systematic em-
ployment of the forms of spicules in the fossil Calcispongie.

HLASMOCGLIA, Rémer.
Elasmojerea, From.
Sponge consisting of one or several arched laminz, more or
less grown together, which are pierced throughout their whole
longitudinal axis by numerous round stomachal cavities of
equal thickness. ‘These tubes are placed in one or more rows ;
and their round orifices are situated at the upper margin.
Radial canals wanting. Skeletal fibres coarse. Surface and
walls of the tubes porous.
This genus was first described by Fromentel (Introd. p. 34)
under the name of Hlasmojerea ; but F. A. Romer showed that
it had nothing to do with Jerea, but must be placed near
Siphonocelia. He therefore altered the name to Hlasmocelia.
Although Rémer’s 2. seguana is not identical with Fro-
mentel’s Hlasmagerea sequana, but belongs to Peronella du-
mosa, From., the remark is nevertheless correct that the
Elasmocelie consist only of Peronelle serially arranged and.
grown together by their sides. They perhaps form only a
section of Peronella, coming nearest to P. dumosa; but the
external habit is so peculiar that I would retain the genus
Elasmocelia.
All the species are from the Lower Cretaceous.

Sponge obconical or top-shaped, simple, or polyzoic by

broadly truncate, with a central, very deep, funnel-shaped
stomachal cavity. Surface porous, with horizontal rings of
growth. A true canal-system is deficient ; but the sponge-
body consists of successively formed horizontal layers of
coarse anastomosing fibrous tissue, which have between them
narrow interspaces for the circulation of water. |
Among the spicules of the skeletal fibres I believe I have
recognized simple bacillar spicules as well as triradiates.
Some of the latter are four or five times as large as the others.
This genus, united with Siphonocelia by Fromentel, from
its laminar structure, which somewhat reminds one of that of
certain Rudistes (Radiolites and Spherulites), and also, from
the unusual thickness of the wall, the truncated upper margin,
and the occasional singular budding of the latter, acquires so
peculiar an aspect that it can readily be distinguished from
Peronella.
In the French Neocomian only monozoic individuals usually
occur; but in the North-German Hils polyzoic specimens are
also found. Through Prof. Ottmer of Brunswick I have ob-
tained a number of specimens which leave no doubt that
Limnorea centrolevis, Rém., is united by all transitions with
simple individuals of the form of Conoceelia crassa, From.

VII.— Observations on the Chlamydodere or Bower-birds,
with Description of a new Species. By Joun GouLp,
F.R.S.
THE Bower-birds are so named from their extraordinary habit
of building ‘ playing-places”’ or ‘‘ halls of assembly,” placed
on a thick platform of sand, turf, &c., variously decorated
with shells, bleached bones, or any glittering substance which
may be at hand. ‘The Bower-birds are naturally shy in dis-
position, and consequently seldom seen in the forest unless
closely looked for. In affinity they are generally supposed
to be allied to the “ Birds of Paradise,” an opinion with
which I am inclined to agree. BesidéS these extraordi-
nary feats of building “ playing-places,” constructed of. fine
branches of trees, where the birds meet to have their gam-
bols, most of them are also distinguished by peculiarities in
their plumage. Many of the species have a decorative patch
at the nape of the neck of an extremely beautiful lilac; others
have no such decoration. One pleasing feature belongs to
the members of this group: it is that they appear to become
easily domesticated, bearing captivity well; and if one or
more are placed in an aviary, and materials be thrown about,
they commence building their curious bower, and play and
coquet in the most pleasing manner: this was the case with
the Bower-birds at different times in the Zoological Gardens.
It must not be supposed that these structures on the ground
are for the purpose of breeding: the little known on this sub-

ject is that Chlamydodera maculata makes a round, mode-
rate-sized, cup-shaped nest, like that of the English jay
(Garrulus glandarius), and placed among the branches of
high trees.
The new species, Chlamydodera orientalis, is a native of
Queensland, and tolerably common at Port Denison. In size
it is about the same as C. nuchalis, whose habitat is on the
opposite part of the continent. The bird figured by Jardine
and Selby was from one of these western countries; it is also
the bird spoken of by Capt. Grey in his travels, as well as
the one mentioned by the officers Bynoe and Dring of the
surveying-ship ‘Beagle;’ lastly, specimens were brought
over to this country by the lamented Elsey, who collected
them at the Victoria river.
It is not by writing ever so minutely that I can make the
public perceive the difference in these two nearly allied birds ;
but if a series of skins from both countries are placed side by
side it will be at once perceptible. The great peculiarity in
the present species (ordentalis) is the barring of the upper
plumage, almost approaching to that of C. maculata and C.
guttata. This new bird is less silky in its plumage than the

VIIL—A third Contribution to the Knowledge of the Ceto-
niides of Madagascar. By Cuartes O. WATERHOUSE.
Tue British Museum has recently received some interesting
additions to the collection of Cetoniide from Madagascar.
All the species here described are from the neighbourhood of
Antananarivo (with the exception of Coptomia elegans, which
is from Fianarantsoa), and were collected by Mr. Kingdon.
Stenotarsia picta.
Elongata, subparallela, nigro-picea, supra nigra, velutina; thorace
linea circumdata flava; elytris ad suturam impressis, singulis
macula triangulari ante medium ferruginea lineisque duabus
tenuibus flavis. ¢ Q.
Long. 7 lin.
This species has much the appearance of some narrow
species of Macronota; but the legs and tarsi are long and
slender, as in Stenotarsta, and the elytra slightly embrace the
abdomen. Above dull velvety black, except the head, which

is pitchy. Thorax a little broader than long, obliquely nar-
rowed in front of the middle, subparallel posteriorly, only
very slightly sinuate at the sides, broadest at the posterior
angles, the base straight, with a pale yellow line all round
the margins, but not touching the posterior angles. Scutel-
lum yellow at the apex. LElytra deflexed at the sides and
apex, at the shoulders much broader than the thorax, then
suddenly narrowed, subparallel to the apex ; each elytron with
a rusty-yellow triangular spot at one third from the base;
this spot is bordered posteriorly by a narrow yellow line; a little
beyond this is a second yellow line, which ascends obliquely
towards the suture; the apex is truncate and is bordered with
yellow. The second segment of the abdomen has a greenish-
yellow fascia; and the fifth segment is margined with the same
colour. ‘The anterior tibie are tridentate in both sexes. The
pygidium in the male is oblong, rounded at the apex, and
thickly punctured, the punctures each having a very short
yellow hair; in the female there is a very deep ovate impres-
sion at the apex.
Sometimes the rusty spot on the elytra has a short curved
line above it on the side, and there is also another line con-
necting the spot with the suture. The sternal process is in
the form of an equilateral triangle, its sides sloping.
Note.—In the same collection with the above there was a
male example of S. discotdalis, differing from my original
type in having the discoidal patch on the thorax divided
into three black spots.
Euchilia picipes.
Oblonga, nitida, viridi-olivacea ; elytris striis decem nigris impressis ;
tibiis tarsisque piceis.
Long. 83 lin.
This species is very close to #. costata, and might be easily
mistaken for it. It is, however, of a darker, more olive
green, tinged frequently with blue; the thorax is less ample,
rather less convex; the clypeus is less strongly punctured ;
the lines on the elytra are finer, and the lateral deflexed por-
tion is not bounded above by a well-marked ridge, but is more
gradual; the upper part of the femora, the tibia, and tarsi are
deep pitchy red; the three teeth on the anterior tibiz are less
acute, extremely blunt in the female.
Euchilia costifera.

Long. 73 lin.
General form of £. sulcata, but with the thorax less ample;
the shoulders of the elytra are more prominent, and are more
excised immediately below. Bright bluish green, shining ;
clypeus rather thickly and finely punctured. Thorax convex,
rather obscurely and not very thickly punctured. Scutellum
smooth. LElytra with the suture much raised; each elytron
with four slightly sinuous impressed lines, which are very
obscurely punctured ; the second and fourth interstices narrow
and costiform ; the first and third interstices have a few large
punctures in a line. Pygidium with punctures scattered over
the surface. In the female the three teeth of the anterior
tibiz are a little closer together than in the male.
Euchilia cupricollis.
Viridi-olivacea, nitida; fronte, thorace, scutello, elytrorum disco,
pygidio corporeque subtus plus minusye rufo-cupreis, tibiis tar-
sisque piceis. @.
Long. 73 lin.
Very close to E. picipes; but, besides the coloration, it
differs from that and all the other species in having the base
of the thorax gently arcuate, and not at all sinuate before the
scutellum. ‘Thorax convex, finely coriaceous, the sides sub-
parallel and gently sinuate behind the middle. LElytra each
with five black strie, the deflexed margins not bounded above
by a marked ridge. Pygidium obscurely and not very thickly
punctured. Anterior tibie with three strong sharp teeth.
The coloration closely resembles that of E. puncticollis, W.,
but that has the thorax thickly punctured, and has a slight
sinuation before the scutellum.
Euchilia tarsalis.
Olivaceo-viridis, nitida; thorace crebre fortiter punctato, sat
pubescente ; elytris punctato-striatis, interstitiis secundo quarto-
que costiformibus; pygidio parce punctato, pubescente, tibiis
tarsisque subtus ciliatis.
Long. 8-83 lin.
Clypeus deeply incised, finely punctured ; the forehead more
distinctly punctured, and having black hairs arising from the
punctures. Thorax convex, thickly and strongly punctured,
the base very gently arcuate, not perceptibly emarginate before
the scutellum. Elytra each with six well-marked impressed
sinuous lines, which are strongly punctured; the suture and

the second and fourth interstices raised, this latter abbreviated ;
the first and third interstices with some strong punctures ; the
subapical callosity obtuse, the apex smooth. The pygidium
with a few punctures. Tarsi black.
The male has the anterior tibie with three acute small teeth,
the anterior tarsi short and extremely thick; the posterior
tarsi as long as the tibia, moderately stout.
The female has the three teeth of the anterior tibize close
together. The anterior tarsi are short and more slender, the
posterior tarsi are much shorter than the tibia, less stout than
in the male.
This species is very peculiar, and recedes somewhat from
Euchilia, but agrees better with that genus than with Cop-
toma.
Pygora bella,
Viridi-prasina, subtus plus minusve cyaneo micans, nitidissima ;
clypeo piceo ; thorace olivaceo, linea mediana tenui lateribusque

levyiter convexo, cyaneo, parce punctato; pedibus pallide piceis.
Long. 6 lin.
Head and clypeus very thickly and rather strongly punc-
tured, the latter very slightly emarginate. Thorax moderately
thickly and distinctly punctured, nearly parallel at the sides
to a little in front of the middle, then obliquely narrowed
anteriorly, olive-green (or dark cyaneous), with a fine mesial
line and the sides pale green. Scutellum smooth, pale green.
Elytra each with four strong striz; the third interstice nearly
flat, the others convex ; the shoulders pitchy.
The male has two acute teeth to the anterior tibie, with an
indication of a third; and the first abdominal segment has a
white spot on each side.
The temale has three acute teeth to the anterior tibie ; and
the abdomen has no spots.
In the same collection with the above were two examples
of rather larger size (7 lines), which have the sides of the
thorax, the scutellum, and the sides of the elytra bright golden
coppery ; the colour of the thorax and elytrais less dark. I
believe them to belong to the same species.

This is a much broader and flatter species than the prece-
ding. I have not seen the male. The mesial line on the
thorax is smooth.

This species varies in colour. Sometimes it is entirely
green or dark olive; the elytra are generally darker at the
base, sometimes green with the base purple-blue or violet,
with a pale yellowish-lilac ovate spot a little way from the
base ; sometimes the whole elytra dark blue. The clypeus
is closely and rather finely punctured, the forehead more
strongly and less closely punctured. ‘Thorax very convex,
not much narrowed in front of the middle, subparallel behind,
not angular at the sides, gently arcuate at the base, not emar-
ginate before the scutellum, smooth on the disk, rather thickly
punctured towards the sides. Scutelium smooth. LHlytra
each with six strongly impressed punctured lines, the fifth
and sixth closer together, not impressed posteriorly, the suture
and the second interstice raised; there are generally some
large punctures around the shoulders and on the first inter-
stice; the deflexed margins are rather thickly punctured, the
apex generally nearly smooth. Pygidium evenly convex,
obscurely and not very thickly punctured. Mesosternal pro-
cess almost none. ‘Tibiee and tarsi pitchy.

Head thickly and strongly punctured, pubescent, green on
the vertex, the clypeus pitchy. Thorax obliquely narrowed
in front of the middle, subparallel behind, scarcely emarginate
before the scutellum, rather strongly and thickly punctured
(especially in the female), green, with a large triangular patch
on each side of the disk of olive, pitchy, or lilac colour, the
sutural line often coppery. Scutellum smooth, green or cop-
pery. Elytra green, with the space between the first and

Long. 53-7 lin.
Almost identical in form and colour with P. scapha, but is
at once distinguished by the absence of the lines of strong
punctures on the elytra, which are only represented by a few
punctures in a slight transverse impression a little behind the
middle. ‘The clypeus is delicately punctured in the middle ;
and the lateral longitudinal impressions are not strigose as in
scapha. The apex of the elytra is almost destitute of punc-
tures; the pygidium is finely and densely strigose. The tibix
and tarsi are sometimes pitchy.
Varvety—Thorax and elytra brownish red, with the dis-
coidal impressions of the elytra and the scutellar region black.
Pygidium pale brownish red.
Pantolia polita, Waterh.
I described this species from a single example. We have
now received several specimens of both sexes. Some of the
examples measure as much as 8} lines in length. Among
them were two or three examples which, instead of being en-
tirely black above, have the sides of the thorax broadly .
margined with pitchy red; the margins of the elytra and a
fascia across the middle (slightly interrupted at the suture)
are also bright pitchy red. 'The tibiee are pitchy. Some of
the smaller specimens have the lines of punctures on the
elytra more extended, especially towards the shoulders and
along the suture towards the apex; these specimens have the
clypeus more punctured, and the thorax is sparingly and ex-
cessively finely punctured instead of being smooth: three of
these smaller examples have the sides of the thorax and the
entire elytra obscure pitchy.

Very close to C. 4-maculata, W., but much smaller, the
thorax with a few punctures scattered over the surface, the
elytra distinctly striated, the green spots differently placed,
the pygidium sparingly punctured in the same way, but with-
out any transverse ridge at the base, the sternal process short
and blunt. Clypeus finely punctured, very slightly emargi-
nate at the apex. Scutellum and elytra smooth, the latter
each with four well-marked impressed lines, which do not,
however, reach the apex ; there is a lateral green line extend-
ing from the shoulder to the apical callosity, an oblong green
spot behind the middle between the third and fourth stria,
and the apex of the suture is also green; the apical callosity
is obtuse and is at the extreme apex.

The largest species of this group at present known to me.
Uniform shining grass-green, without any punctuation above
or on the pygidium, except a few punctures between the eyes.
The sides of the metasternum are sparingly punctured. ‘The
propygidium is strigose.
The only species which this resembles is Coptomia muta-
bilis, W. (Ann. & Mag. Nat. Hist. 1878, i. p. 139), from
which it differs in being of a more elegant and elongate form,
in the longer legs and tarsi, in the absence of the strigosity
on the subapical callosity of the elytra, and in having no
punctures on the pygidium. ‘The sternal process is more
slender.

Very close to C. mutabilis, but less bright green, more
castaneous below, of a narrower form, and with the sternal
process much more porrect. Pale olive-green above, the
head and thorax more generally showing a castaneous or
coppery tinge. The head moderately thickly punctured be-
tween the eyes. Thorax smooth. Elytra with very ob-
scurely punctured lightly impressed lines; the side of the
apical callosity and the apex rather closely strigose. The
pygidium with distinct punctures scattered over the sur-
face.

Most nearly allied to C. nigriceps, W., but quite distinct
by its coloration from all known species. The black on the
suture of the elytra is narrow, but dilates towards the- base
and surrounds the scutellum; the transverse mesial fascia is
broad. The pygidium is very densely and extremely finely
strigose. ‘The anterior tibiz are a little more slender than in
the female, and the three teeth are less strong; the abdominal
impression is very slight.

Very robust, especially the female. Castaneous, the elytra .
darker than the rest of the body. Thorax convex, regularly
narrowed anteriorly, finely coriaceous, thickly punctured,
rather more strongly in the female than in the male, with
two small olive-black spots at the anterior margin (close
together), and two large triangular patches behind, united at
the posterior margin. Scutellum coriaceous and finely punc-
tured, black, with a mesial brown line. Elytra each with
two slightly raised lines, the suture blackish. Pygidium

The male has the elytra with five or six lines of rather
strong punctures, the lateral margins and the apex densely
rugulose.

Thorax elongate, gently narrowed in front of the middle,
behind the middle moderately narrowed and gently sinuate,
with a fine mesial carina above; the surface covered with
large, closely placed, ovate punctures, which have a tendency

1X.—On some Spheroidal Lithistid Spongida from the Upper
Silurian Formation of New Brunswick. By Prot. P.
Martin Duncan, F.R.S.
[Plate IX. ]
In 1875 Mr. G. J. Hinde, F.G.S., sent a number of fossils to
the Geological Society with a short paper, which was published
in abstract*. He described them as coming from the cal-
careous shale of Lower Helderberg or Upper Silurian age in
New Brunswick, and felt disposed to classify them with the
Tabulata ; but he had not, at the time, the opportunity of amply
examining them.
The spheroidal shape of the fossils and their evidently former
free existence attracted my attention a few weeks since, as I
was investigating the similarly shaped organic remains from
the Himalayas, which have been classified under the order:
Syringospheridze amongst the Rhizopoda. Mr. Hinde very
kindly allowed me to investigate the structure of the fossils
he had sent; and this communication is the result of their ex-
amination.
The four specimens of the spheroidal fossils which have
come under examination are oblate, symmetrical, rounded at
the top and bottom, and slightly produced at the equatorial
bulge. The heights are 74, 7°, @ inch, and the breadths re-
spectively 1,4, inch, 1 inch, and ;% inch. It would appear
that the growth was more in height than in breadth. The
fourth specimen had been polished on its poles and equator
in more than one place, and therefore could not be measured
correctly.
The outside of the fossils is, where the organism has been
preserved, minutely granular to the eye, and is covered with
minute depressions between the granules. A low magnifying-
power shows that the granules are separate, rounded, minutely
irregular on their surface, about as high as broad, and that
the three or four which are round each depression are imper-
fectly connected by low and narrow processes. The granules,
however, are often broad and irregular, and form much of the
sides of the depression; their general equality in size and
the vast number of the pore-like spaces included by them are
evident enough.
In some places on the surface, where the weathering has
been greater, or where rubbing has removed more or less of it,
and especially at the edges of the abrasion, the bottom of the

Spongida from New Brunswick. 85
pore-like depressions may be seen as spaces filled with dark
homogeneous calcite. ‘They are very minute, of different
sizes, and oval, square, or more or less triangular in outline.
There are no points projecting into them; and neither septa
nor spiculate septa-like processes exist.
Where abrasion has been carried on so as to destroy the
granules and partly to level the intermediate narrow processes,
the structures become very comprehensible. A reticulate ap-
pearance is presented, the white calcareous meshes of the
skeleton surrounding dark polygonal or oval spaces. The
breadth of each space or reticulation is from ;1, to =; inch;
and the sides are formed by narrow irregular cylinders, whilst
the angles are swollen and faintly nodular. These nodular
parts are the bases of the external granules. No septa or pro-
jections resembling those of the Perforata exist.
Slightly deeper abrasion and polishing exhibit indications
of the junction of the irregular cylindrical sides of the meshes,
sometimes at the nodules or angles, or in the midst of the
cylinder, one part being received into the other. The swellings
at the angles are less, but are still prominent features; and two
conditions of the environed area are to be noticed: in one, and
the most usual, the space is filled with clear dark calcite, and
no structures are seen in it; in the other a white or opalescent
film intrudes from the sides nearly to the centre, leaving there
a small circular space of dark calcite. This second condition
resembles an imperfect tabula belonging to an endotheca, such
as is present in Chetetes. In many spaces there is perfect
occlusion ; but the texture of the substance thus simulating a
perfect tabula, is not that of the calcareous mesh, it is that
of infilling foreign matter. This is proved to be the case in
radial sections.
The areas differ much in size ; but none are very large, nor
are any surrounded by sets of smaller ones in regular series.
Their measurements correspond nearly with those given on the
surface.
At this stage of the inquiry, if a good illumination is em-
ployed, with a magnifying-power of about 30 diameters, the
latticework of the calcareous skeleton of the fossil, seen on a
deepish abrasion, is found to consist of separate elements con-
joined, each being resolvable into two prongs and a stem of
the same thickness and length; and at their junction a nodular
process or another stem exists. A triradiate or quadriradiate ©
spicule with straight or bent limbs irregularly papillary here
and there on the edge, is the element ; and at the extremities
of the limbs there are swellings not unlike frills, some being
rather convex there and others concave ; and the convexity
86 Prof. P. M. Duncan on Upper Silurian
of one is embraced by the concavity of a neighbouring
spicule.
Radial sections were made of some of the specimens, and
were examined by reflected, transmitted, and polarized light.
The dark-spot method of illumination was particularly suc-
cessful. The powers employed were from 30 to 450 diameters;
and the investigation was assisted by the action of dilute
hydrochloric acid as a solvent.
The original hard parts are white and nearly opaque, and
when cut across and polished are almost homogeneous, only
minute granulation being visible under high powers. They
consist of carbonate of lime, and are white by reflected light,
and either colourless or light brown or grey by transmitted
light, the central dark-spot illumination producing an exqui-
site surface-opalescence. Polarized light produces but slight
colour; but it indicates a vast number of minute refractive
points: crystals of calcite are not seen, however; and there
are no cleavage-planes in the hard original parts. ‘The fossils
are infiltrated with clear transparent or rather dusky calcite
with very few cleavage-planes, and in some places giving indi-
cations, under polarized light, of a more or less acicular or
fibrous structure, like aragonite. Rhombs of calc spar exist
here and there; and the intensity of the colours elsewhere,
under the crossed Nicols, varies much. Near the periphery
of the fossils, what may be termed orbicular calcite covers
the skeleton and intrudes in undulating contours on the homo-
geneous calcite; and this margin acts differently on light to
the mineral on either side of it. In a few places the margin
looks almost membranous, if such a term is admissible, whilst
within it and near the skeletal elements the structure is some-
times acicular and close, or it presents the usual appearance
of infiltrated calcite. It is the projection of this orbicular
layer, with or without drusy cavities, which gives the ap-
pearance of asemiclosure of the canals here and there.
On the whole, this remarkable layer is in the position of
the mass of dermal spicules in some recent Lithistids; but no
trace of any can be seen.
Radial sections through the centre of the fossils show that
there is a small space in the centre which is occupied by an
irregular reticulation of not universally continuous skeletal
elements. The meshes are wide, and are either without
any definite shape, or are quadrangular or pentagonal in
outline. In one section there are separate spicules in the
centre.
From the edges of this central space a great number of
radiating, more or less straight canals pass to the periphery,

each being pervious throughout and without tabule. Each
is in relation with those on all sides of it by means of regular
three-, four-, or six-sided spaces in its walls. The canals are
subequal ; but here and there some are larger than the others.
They arise from the central space, bifureate occasionally, thus
increasing in number, and end at the surface in the areas be-
tween the nodules and reticulation seen there. The largest
canals measure = inch in diameter, and the smallest about
tro Of an inch. Their length varies with the size of the
specimen ; for they constitute the larger part of the fossil.
_ They are more or less hexagonal or quadrangular in sec-
tion, and are filled with the minerals already noticed. They
were patent throughout before fossilization took place, and
neither cross pieces, tabule, nor septa encroached on them ; but
it should be noticed that under a hand-lens tabulate structures
appear very evident here and there; but they are resolved into
parts of overhanging canal-walls under the compound micro-
scope and careful focusing.
The canal-walls and their reticulation, as well as that on the
outside, which is the expression of the outermost skeletal
element of the canals, and the reticulation of the central part,
are composed of similar structures, which are closely united
in the first, and less so or separate in the last place.
The union of the spicules (for such are the skeletal elements)
is often so intimate that the canal-walls appear to be con-
tinuous. But in thin sections, and in certain places in others,
the skeleton resolves itself into numerous combinations of
spicules closely resembling those of the Tetraclade Lithistide
in shape and method of junction.
These canal-wall spicules resemble those which are free or
nearly so in the central space. In no instance, however, has
a central canal, or a canal in the three or four arms of a spicule,
been observed.
Typical spicules, from the central space, consist of three
arms in one plane uniting at a common point, from which
another arm may spring and be in a plane at right angles,
more or less, to the others. These tripod-stemmed spicules
are often ragged or papillate on one or more surfaces, appear
solid under the microscope, and are often compressed. ‘They
differ in size, and are usually the largest in the outer parts of
the central space, where the canal-system is commencing. The
simplest form of spicules has two straight or slightly curved
arms, which are widely apart, forming an angle of 35° to 45°
where they meet and join a smaller and shorter third, which
lies in a different plane. The larger arms are flattish; and
their opposed surfaces (sometimes the others) are nodular or
88 Prof. P. M. Duncan on Upper Silurian
marked with irregular swellings, but the rest plain. Their
tips are slightly expanded and faintly frilled. The smaller
arm is nearly cylindrical, but more or less conical.
Under transmitted light these spicules appear nearly homo-
geneous ; but polarized light enables minute granules,
crystals, and very rarely cleavage-planes to be seen; never-
theless the refraction of the mineral is insufficient to produce
much colour on crossing the Nicols.
The breadth of the arms is from =1, to z4, of an inch; and
the length is from . to rather more than 7}> inch. Some of
these spicules, whilst retaining their general typical form,
differ much in external aspect. They may have two arms
slightly bent, expanded at the end, and rough (not on the
sides forming the angle), and the third visible arm may be
stunted; or the arms may be equal and straight, with a
fourth like a well-developed knob or a long shaft.
Spicules from the canal-system are invariably joined with
their neighbours to form a latticework. They consist of
normal trifid forms, of trifid forms with short and large
third limbs, of four-limbed forms, the extra limb resembling
the others or longer or shorter. In some the fourth limb is
situated at the junction of the other three, and, being in a
plane at right angles to them, produces a general swelling at
the junction, so as to interfere with the angle of the union of
the limbs, it being occasionally replaced by a concavity or
even a slight swelling. The limbs are usually plain on one
side and roundedly dentate, or irregularly rounded and slightly
spinose. ‘The junction of the spicules with their neighbours
may take place through the ends of the limbs uniting in a kind
of suture, or by a joining which leaves no indication of its
exact position. The skeleton thus formed is very irregular at
the outer part of the central space, and then, as the canal-sys-
tem commences, becomes very regular. The symmetrical
arrangement of the spicules of the sides of the canals is very
exact; and one canal is separated from its neighbours by
common latticed walls. The diameter of the canal-space is
greater than that of any of the openings in its walls; and the
one is produced by four or five spiculate series extending
around a space ; and the others are the spaces left between the
arms of neighbouring spicules.
The junction of the spicules is usually by the ends of the
limbs; and the exceptions are rare; but in the centre of the
body of the fossil instances are to be seen where the end of
the limb of one spicule is attached to the middle of the cylin-
drical limb of another. The method of normal junction of
different spicules is by the clasping and surrounding of a
Spongida from New Brunswick. 89
smaller liml by a frilled or irregular cup-shaped expan-
sion of a slightly larger; and the line of suture is visible. It
often happens that the spicules do not quite touch, and the
expanded limb-end of one and the corresponding smaller ter-
mination of the other and opposite limbs are separated by a
microscopic interval. Sometimes one limb, frilled or digitate
or simply rounded, projects, without that of any other spicule
being near ; and deformed specimens of these solitary parts are
not unusual. Here and there the junction, as has been noticed
already, is by direct fusion; and this occurs in the broad flat
spicules of the canals more than elsewhere.
As the canals are close, and radiate to the periphery, in-
creasing in number by bifurcation not far from the limits of
the central space, each one must be surrounded by several
others. Four, five, or six canals may environ ihe canal
under observation ; and a tangential section closely reproduces
the appearance seen in abraded specimens when looking down
on the reticulate ends of the canal-skeleton from the outside.
Hach canal is therefore polygonal in section (tangential). There
is no duplication of the wall of a canal; and this structure is
merely the space left by the interlacement of numerous sets of
spicules in longitudinal series.
The symmetry of the parts of these spheroidal fossils is
great; and there is a very constant resemblance, in every part
and in different individuals, of the skeletal elements and their
disposition.
No separate spicules differing from those already noticed
are present ; and the tubulation of the spicules is not seen.
A superficial examination of the specimens would lead to
the belief of their being Perforata or Tabulata, amongst the
Actinozoa and Hydrozoa; but the areolation and structure of
the skeleton is not that of the one, nor are there tabule or the
peculiar hard parts of the other group.
The shape of the skeletal element in the mass is not unlike
that of some of the flat Manons or Jereas of the Cretaceous forma-
tion. The arms of the spicules do not bifurcate, however. In
the general arrangement of the spicules in the canal-systems
there is some resemblance to that in Zuronia, and there is only
a slight one to that of Aulocoptwm, Oswald, which is the only
hitherto described Paleozoic organism which resembles the
Tetraclade Lithistids. In this form, which is free, hemi-
spherical, and even sometimes spherical, there is a central
cavity. |
The resemblance is not sufficiently great between the new
form and Aulocopium to place them together in the same
classification ; nevertheless there can be no doubt that both
90 Prof. P. M. Duncan on Upper Silurian
have the general and some of the special characters of those
Lithistid Spongida which belong to the Tetracladina.
But the fossilization of the skeletal parts of the new form is
not that which is characteristic of mechanical infilling after
outgoing of a former mineral—such, for instance, as is seen
in calcareous replacement of siliceous spicules. The calcareous
mineral of the skeleton is not in distinct crystals, and cleavage-
planes are rare; on the contrary, the mineralization re-
sembles that of fossils which were originally of carbonate of
lime.
There is a point of some interest which offers some evi-
dence that the original skeleton was not siliceous. In the
midst of the long canals, in their interspaces, and passing
over the skeletal parts in close proximity are many relics of a
large form of Paleachlya penetrans, Dunc.; and in sections
the passage of the tubes of the parasite through and along the
inside of the spicules can be seen. Usually the tube is
crammed with the spherical spores; and they frequently
extend beyond it and collect in masses. In one instance
they crowd a spicule. The tubes and spores are, as in the
specimens described in a former number of the ‘ Quarterly
Journal of the Geological Society,’ carbonized.
It does not appear to me to be likely that these parasitical
plants penetrated after the calcareous fossilization of the inter-
stices was completed; they must be regarded as having grown
at the expense of the organic matter of the spicules during the
lifetime of the organism. Moreover it must be conceded,
from the knowledge we have of the physiology of the Achlya
group, that it is not probable that they could penetrate and
live in silica.
These little spheroidal fossils are, then, of considerable
interest; and the more they are critically and carefully exa-
mined with all the appliances of the microscope, the more do
they resemble the Spongida. Their texture is not that of
the perforate coral; and they have no accurate and minute
resemblance to’ the Tabulata; but they are most suggestive
from their transitional appearance. -
Tf all the modern Lithistids were siliceous, there must have
been a former mimetic and calcareous group of Spongida. Or,
as the Lithistids appear to have been rare in the earlier fossili-
ferous rocks, and Aulocopium of the Silurian is the first known,
it is possible that a group of Calcareo-Spongida lived contempo-
raneously and became extinct or merged into a higher form
as the parent of Zoantharia Perforata. I have named the
fossils, after their discoverer and their shape, Hindia spha-
roidalis. =
Spongida from New Brunswick. 91
Genus HINDIA.
The body is free, without an involution of the texture, and
consists of a small central space occupied by spicules which
soon form a series of bifurcating, long, straight, radiating
canals, which open at the surface. The spicule element is
calcareous, more or less in the shape of a stemmed tripod,
with four limbs, and swollen or fringed at the ends, where
junction takes place in the others.
The skeleton is remarkable for its regularity.

The sponge-body is spheroidal. On the surface are pa-
pulliform eminences corresponding with the ends of canal-
spicules. Centrally the spicules are unattached, are tri-
pod-stemmed im shape, with swollen extremities, and have
papillose imbs. Canal-system occupying much space; canals
straight, narrow, radiating, opening into their neighbours, and
formed by combinations of tetraclade spicules resembling those
of the central part, and very regular in shape and size.

The Great Atlus Moth of Asia (Attacus atlas, Linn.), with a coloured
Plate of its Transformations. By Puiu Henry Gosss, F.R.S.
8vo. London: West, Newman, & Co. 1879.
In this little book that veteran naturalist Mr. Gosse gives a short
account of his experience in rearing the larve of the great talc-
spotted Atlas moth of South-eastern Asia. The species is one of
those silk producing Bombyces to which attention has been of late
years directed in consequence of the fatal diseases which have
attacked the common silkworm; and, according to Mr. Frederick
Moore, it is from its cocoons that the Tusseh silk of China is ob-
tained. In this country, at any rate, the cultivation of Attacus
atlas would seem to be attended with considerable difficulties ; for
out of eighty larvee Mr. Gosse only succeeded in bringing one to what
would appear to be the mature stage (after five moults); but even
this did not spin up. The author gives a detailed description of the
lary in their various stages up to the sixth, as just mentioned,
when they are large handsome caterpillars of a general delicate
pale green tint, and adorned along the back with numerous spini-
form processes ; and he completes his account of the transformations
by describing the cocoon and pupa from a specimen imported in
that state. Coloured figures are given of the eggs and larve (the
latter in their first, fourth, and sixth stages), and of the pupa and
cocoon. The remarks on the natural history of the insect, and the
details of its author’s proceedings in his attempt to rear the larve,
contained in this little work will prove both interesting and useful
to all who devote their attention to this branch of entomology.
Supplement to the Second Edition of ‘ Acadian Geology, &e. By
J. W. Dawson, M.A., LL.D., F.R.S., &. S8vo, 102 pp. Mac-
millan and Co., London &c., 1878.
Tunis Supplement, containing additional facts as to the geological
structure, fossil remains, and mineral resources of Nova Scotia, New
Brunswick, and Prince-Edward Island, constitutes an appendix of
new matter for the Third Edition of the ‘ Acadian Geology,’ the
Second Edition of which we noticed as a most satisfactory and
useful work in 1868.
Principal Dawson, of M‘Gill University, Montreal, collecting to-
gether all the important facts illustrative of the geological structure
of the Dominion, long ago worked out not only a local natural
history, but a cosmopolitan view of his great subject, and elucidated
it with knowledge obtained from every source available to geologist,
mineralogist, and naturalist.
Still collecting and comparing facts and opinions, the author has
much to add about the strata, fossils, and mineral productions, very
little to retract as to hypothetical views in matters of dispute, and
much to enforce in corroboration of his views of modified uniformi-
tarianism, glacialization of a mixed character, the origin and nature

of the coal-growths, the existence of a Devonian flora, and the oceur-
rence of fossils in the Lower Paleozoic rocks. His comparison of
the old rocks of the Canadian regions with those of other parts of
the world, in the Table at p. 92, is very interesting and suggestive.
From the Ludlow beds downwards to the older eneisses of Scotland
and Scandinavia, including the lately recognized Pebidian and
Dimetian series, Dr. Dawson finds probable equivalents, of definite
characters and position, in Canada and its vicinity.
The new edition of his work, with its well-considered additions,
will prove to be valuable to the increasing population of British
America, in the presence of the enlightenment of modern education,
and the necessity of understanding the nature and whereabouts of
the mineral productions of the rocks and the capabilities of the soil.
The Gault, being the Substance of a Lecture delivered in the Weod-
war van Museum, Cambridge, 1878, and before the Geologists’
Association, 1879. By F. G. Hiro0n Price, F.G.8. 8vo,
81 pp. Taylor and Francis, London, 1879.
Iy this very useful history of the Cretaceous division of strata
known as “the Gault,” the author gives a special description of the
Gault at Folkstone, bed by bed (pp. 10-23); a more general
account of this formation as seen at the exposures along its outcrop
in the various counties from Kent to Devonshire and Yorkshire
(pp. 24-34); and a sketch of the Gault in France (pp. 34-42).
The Greensand of Blackdown, the “Red Chalk” of Norfolk and
Yorkshire, the various phosphatic and other nodular beds, and the
results of the deep borings penetrating the Gault near London are
specially noticed. An extensive and synoptical catalogue of the
fossils (pp. 44-81) shows their occurrence at different localities and
their range through the several zones of the Gault.
Resides thus indicating the geographical range of this important
formation in England and France, and correlating the equivalents
of the eleven zones which he recognizes in the Gault of Copt Point,
Folkestone, the author has in view a hydrographical sketch of the
area in which this important Cretaceous formation was deposited
(pp. 8, 9). He notes that its composition varies much in different
localities, according to the depth of water and the nature of the
adjacent lands at the time of the deposition of its component parts ;
also that the fauna varied in the several regions according to the
nature and conditions of change in the water and sea-bed. Fur-
ther, he observes that the clays and sands of the Gault originated
in the trituration of lands and cliffs composed, for the most part, of
Jurassic and Neocomian rocks in what is now England, on the west
side of the Anglo-Parisian Cretaceous basin, of Primary (Palso-
zoic) rocks in the north-east of the basin at the Ardennes, and of
granites, porphyries, Jurassic, and Neocomian rocks on the east and
south-west sides of the basin.
A eareful list of books and memoirs treating of the Gault and its
fossils is given at pp. 1-7.

On the Bedy-cavity of the Sedentary Annelids and their Seqmental
Organs ; with some Remarks on the Genus Phascolosoma. By
M. Cosmovict.
Tne general body-cavity of the sedentary Annelids is divided into
several compartments by diaphragms, which sometimes exist only
in a portion of the cephalothoracic region (Arenicole, Terebelle,
Clymenie), sometimes throughout the length of the body (Serpulide) ;
and then each segment has a cavity more or less independent of its
neighbours. ‘There are also divisions in the opposite direction. In
sections there are seen a central cavity filled by the digestive tube,
and two lateral ones separated from the former by muscular bands
in the form of oblique diaphragms. A communication exists between
all the cavities through the interstices of the fibres of the partitions.
The lateral cavities contain the feet with their retractor muscles
and the segmental organs: these are the pedal cavities.
In Chetopterus pergamentaceus the arrangement of the cavities in
the three vesicular segments is interesting. ‘The median cavity,
containing the digestive tube and the genital glands, does not com-
municate with the lateral cavities, which are occupied by the reno-
segmental organs, except by the segmental pavilion which opens in
the wall of separation.
In the Clymenie the corpora Bojani are very long; and at their
anterior extremity the segmental organs are attached. After the
eleventh segment there are no longer any renal bodies, and in their
place there is a plexus of blood-vessels of remarkable abundance.
The position of these networks is such that we may say that they
represent so many corpora Bojani formed solely by their vascular
framework.
The ovum of these animals is remarkable for the separation into
two parts of the vitelline mass; one of these, the larger one, is
formed of large granules, the other of very small ones. In the
latter is situated the germinal vesicle and the spot, which becomes
strongly coloured by picrocarminate.
Pectinaria belgica exhibits first a pair of very large corpora
Bojani, and then two pairs furnished with segmental organs. The
genital gland is on the median line, on each side of the supranervous
vessel. The animal is as transparent as glass ; and notwithstanding
this the segmental organs cannot be perceived. It is curious that in
less transparent animals these organs have nevertheless been
observed by translucence and tigured.
With regard to the segmental organs in the Errant Annelides, we
find a pair of them in each segment, with a contorted tube having
an internal pavilion and an opening outwards. In the Serpulide
(a family very rich in genera), among the sedentary forms, the same
thing is met with. Lastly, in all the other Sedentaria we find the
segmental organs sometimes free, sometimes annexed to the corpora
Miscellaneous. 95
Bojani, and in the majority of cases we may say that the segmental
organs are independent of those bodies.
Hitherto we have been acquainted with three species of herma-
phrodite Spirorbes ; a fourth must be added, namely Spirorbis com-
munis, which abounds at Roscoff.
In the group Gephyrea, in Phascolosoma vulgare, we find, on the
anterior part of the two long blackish sacs, a tube furnished with a
pavilion with two broad ciliated lips. The structure of the sacs
shows them to be renal bodies, to which the segmental organs are
annexed. The genital gland, male or female, is situate at the base
of the posterior pair of the retractor muscles of the proboscis. The
racemose gland is attached to an elastic thread, which is probably a
blood-vessel. The ovum is remarkable for the presence of cilia at
the surface of the vitellime membrane, which, when obseryed in
front, appears finely striated.
In the subintestinal blood-vessel, in the midst of the elliptical
blood-globules, we find encysted trematodes, which are carried along
even into the papille of the proboscis, by the cilia with which this
vessel is furnished. The above-mentioned papille appear to play a
great part in respiration ; in fact the whole circlet is in communi-
cation with the circulatory apparatus. The globules ascend along
the walls and descend by the centre of the papilla. Processes of
the walls in the interior of the papillary cavity cause the globules
to remain a certain time in contact with the delicate wall of these
organs, and thus facilitate an exchange of gases. This may explain
why the animal, when quiet in a trough filled with sea-water,
exserts its proboscis every moment.— Comptes Rendus, May 26, 1879,
p- 1092.
Morphological Notes on the Limbs of the Amphiumnide, as indicating
a possible Synonymy of the supposed Genera. By Joun A. Ryper.
Little attention has apparently been given to the comparative
history of the limbs of the known species of Amphiuma. Very
young specimens do not seem to have been usually collected for
museums. I have had the opportunity to study such a series, vary-
ing from 6 to 8 inches in length, and about } inch, or a little more, in
diameter ; they were obtained in the vicinity of Biloxi, Mississippi,
and are the property of the Smithsonian Institution at Washington.
From these it appears that the digital elements of the limbs are
variable, or liable to variation, in the same individual; so that in
some the number of digits (two) is characteristic of Amphiwna,
and in others (three) they are characteristic of Murenopsis. This
blending of the characters of the two genera may be illustrated as
follows, indicating the number of digits on each limb by numerals
arranged in fours, the first pair representing the digital formula of
the fore limbs, thus:—(1) 3 3; (2)23; (38)32; and (4) 22;
there was also a form which exhibited no outward indication of
toes on the front pair of limbs, the digits being enclosed in a com-

mon investing integument; this fifth form may be represented in
¢
”) :
this manner, !-5- It is plain, from the foregoing, that at ne very
remote period the two forms which are now believed to characterize
distinct genera were probably one and the same. The three-toed
form (Murenopsis) is said to be confined to the Southern United
States, whilst the two-toed form (Amphiuma) is more widely dis-
tributed, extending further north and also embracing the distribu-
tion of the former. The digital formula of (1) is Amphiwma in the
front pair, and Murenopsis in the hind pair of limbs; that of (2)
is Amphiuma on one side in the hinder pair, and Murcnopsis on the
other. Normal individuals of both genera also occur, as in (3)
and (4); while (5) represents the beginning of the differentiation
of a third generic type, if the number of digits be good and sufficient
to characterize genera. Prof. Cope, who has probably handled
more specimens of Amphibia than any other American naturalist,
informs me that he thinks these variations very uncommon, as he has
never in his experience met with any instance in which there was
as much variation in the number of digits as exhibited in these
Biloxi specimens. They can hardly, however, be regarded as mon-
strosities, as the percentage of varying specimens in this series is
entirely too high. I am inclined to believe that they are simply
instances on the one hand of reversion towards a still older and
more unspecialized type, and on the other of a tendency to become
specialized or reduced, as in the case where the two digits are
covered by a common tegumental investment. If the distribution of
species will in any case serve to throw light upon the differentiation
of genera, I think that in this instance we may assume, with much
show of reason, that the individuals most remote from the centre of
maximum development of species and individuals exhibit the greatest
tendency towards digital reduction. The most northern form, Am-
phiuma, seems to be constantly didactyle, whilst the more southern
forms are both di- and tridactyle, which would seem to indicate _
that the forms most remote from the centre of distribution have been
under conditions tending to produce didactylism synchronously with
di- and tridactylism at the centre aforementioned. This, however,
is only a hypothetical view of the case.
The admission of Murcenopsis and Amphiuma to generic rank, on
account of a difference which is here shown not to be constant, is
doubtful. The digits, which, from the fact of their having under-
gone reduction, seem to be not so much rudiments as vestiges of
former digits, render the legitimacy of the distinction even more
open to question; for I think it cannot be doubted that such a
tendency to degenerate, accompanied with a consequent tendency
to produce synthetic characters, shows clearly that nature has not
yet concluded that they shall be genera, notwithstanding the dicta
and definitions of systematists—Proc. Acad. Nat. Sci. Philad.

On Haptophrya gigantea, a new Opalinid from the Intestines of the
Anurous Batrachia of Algeria. By M. E. Mavpas.
The intestines of the Batrachians harbour a whole world of pa-
rasites, which live in them and multiply with a truly surprising
abundance. Micrographers especially may get from them the finest
harvests of Infusoria and Bacterians. From this point of view I
haye often examined the contents of the intestine of Bufo pantherinus,
Discoglossus pictus, and Rana esculenta, which live in the waters of
the neighbourhood of Algiers. I have always found them richly
populated, and have been able to recognize the following species—
Nyctotherus cordiformis, Balantidium elongatum, B. entozoon, Opalina
dimidiata, O. intestinalis, O. obtrigona, and O. ranarum. Swarming
among these large ciliated Infusoria were myriads of Bodos, Monads,
Ameebas, Bacilli, Vibrios, and Bacteria. All these species have
already been recognized in Europe; but I have also very often met,
in the intestine of the Bufo and the Discoglossus, less frequently
in the frog, with a very fine species of Opalinid, which does not
appear to me to have been described, and which, from several very
curious details of its organization, must greatly interest proto-
zoologists.
This Opalinid may be regarded as the giant of the Infusoria; for
I have measured individuals the length of which exceeded 1 milli-
metre. The body is of a very elongate cylindro-conical form, tapering
from the front backwards. The anterior extremity is pretty strongly
depressed, and nearly twice the breadth of the posterior region, which
measures from ;5°— to ;#§; millim. This depressed portion is
occupied by a circular sucking-disk formed by the retreat inwards of
the wall of one of the broader surfaces, which may be called the
ventral surface. The action of the sucker is ensured by cords of
sarcode which start from its inner wall and attach themselves to the
opposite dorsal wall. The concavity caused by the traction of these
cords is, of course, very slight, but it is nevertheless clearly visible
by the microscope. The animalcule attaches itself to objects by
means of this sucker. The surface of the body is very closely
covered with rows of cilia. Four or five rows may be counted in
too millim.; and in the cavity of the sucker they are half as numerous
again. The cilia, the length of which is ;,°,5 millim., are very close
together, about 13 or 14 in each ;4, millim. These cilia are the
sole organs of locomotion of this Infusorium, the progress of which
is never very rapid,
The integument or ectosare has a thickness of ;4°, millim. and
consists of two very distinct layers—an external one, in which the
continuation of the cilia may be traced in the form of bacilli, and an
internal one composed of transparent and absolutely amorphous
sarcode. This integument is entirely destitute of proper contractility,
se that the animalcule cannot in any way spontaneously modify its
form ; on the other hand, its possesses great elasticity, which enables
Ann. & Mag. N. Hist. Ser. 5. Vol. iv. (
98 Miscellaneous.
the body immediately to resume its normal contour when this has
been modified by any obstacle. The endosare consists of clear and
liquid sarcode, at the periphery of which there exists a layer of large
opaque granules.
The nucleus is free in the general cavity, and, following the move-
ments of the body, can move from one extremity to the other. Its
form is that of a very elongate and rather flat ellipsoidal shuttle.
It may measure as much as ;459, millim. Its substance consists of
an opaque slightly yellowish gangue, in which we see numerous
spherical corpuscles of nucleolar appearance. When, in consequence
of the crushing of the body, a fresh nucleus is placed directly in the
water, its substance contracts, and at the surface there appears a fine
structureless membrane, as in the case of many Infusoria.
The body is traversed throughout its length by a long con-
tractile canal attached to the dorsal face, the pulsations of which,
from one systole to another, last a little more than a minute. This
canal is not rectilinear, but describes numerous sinuosities irregularly
disposed. Its diameter, in the state of diastole, is;j5, millim. It
is furnished with proper walls and thus constitutes a true vessel.
In this character it differs from the contractile vacuoles of the other
Infusoria, which are only temporary cavities hollowed out in the
endosare. The wall of the vessel, which is visible even in the living
animals, becomes still more apparent with coagulant reagents. This
vessel is moreover provided with orifices, which traverse the integu-
ment and open outwards in the form of very clearly visible pores in
the midst of the rows of cilia. These pores place the vessel in com-
munication with the external world, and serve for the issue of the
interior liquid at the moment of systole, and very probably for the
entrance of the exterior liquid during diastole. The pores, seven or
eight in number in large individuals, are placed exactly in a straight
line, at irregular distances on the course of the vessel. They are of
an oval form, and measure ;,3,, millim. in length.
This Infusory multiplies by dividing transversely into segments.
The segmentation is at first indicated at the middle of the length
of the body by a clear band in the endosarc. The nucleus divides
into two; a constriction contracts the body at the point of segmen-
tation ; and the vessel becomes divided in two; the two segments re-
main soldered together. The same operation is then repeated at the
middle of each of the segments, so that we see four segments soldered
together; then a second time at the middle of each of these four
segments, and the body is cut into eight segments still attached to
one another, and completely recalling, by their external aspect and
arrangement, the zoonites of the tapeworms. These segments
afterwards separate; and one always finds many of them isolated in
the rectum of the hosts of this Infusory.
This fine Infusory much resembles the Opalinid found by Von
Siebold in Planaria torva, and figured by Max Schultze under the
name of Opalina polymorpha. If we adopt the generic divisions
established by Stein in the family Opalinide, it will have to take its

Trichinosis in a Hippopotamus. By M. E. Hecker.
M. Heckel describes some observations made by him upon a
young Hippopotamus, about two years old, which died on the
10th of May last in the zoological garden of Marseilles, haying
been received from Egypt about four months before. The animal
was in bad health all the time of its residence at Marseilles; and
its skin showed an eruption of confluent boils. When removed, the
skin showed several lesions in the shape of deep ulcerations, which,
having originated around a hair, had attacked the bulb, and thus
formed a canal leading generally into a great purulent cavity.
Smaller ulcerations led into smaller cavities bounded by a proper
membrane, like true cysts, and filled with creamy pus. The exa-
mination of a section of the muscular tissue surrounding one of
these cysts showed it to contain great numbers of Trichina-cysts,
resembling those of T'richtna spiralis, with which also the enclosed
worm agreed. The cysts, however, seemed to be much more deve-
loped than in the pig or in man.
Upon this curious and interesting fact the author has the fol-
lowing remarks :—‘ I am ignorant,” he says, ‘‘ what relations may
exist between the presence, in the same animal, of T'richina and of
enormous cysts filled with pus; but the fact indicated by me
appears to possess some interest . . . . because it seems to prove
that the Pachyderms, more than other animals, are exposed to the
spontaneous development of this terrible parasite—an important
point which may serve to throw some light upon its hitherto un-
known migrations. It has been attempted to explain the frequency
of the Jrichina in the pig, by the consideration of the voracity and
filthy habits of that animal. The fact to which I now call atten-
tion seems to protest against this opinion; for the hippopotamus by
no means shares in the mode of existence and the tastes of the pig;
and we can hardly suppose that captivity, by the special diet which
accompanies it, could have a marked influence upon the deyelop-
ment of the Nematoid worm.”—Comptes Rendus, June 2, 1879,
p. 1139.
On the Apparatus of Sound in some South-American Fishes.
By M. W. Sorensen.
During my residence, in 1877 and 1878, at the mouth of the
Riacho del Oro, in the Rio Paraguay, I was enabled to make some
investigations into the mode in which several fishes of these rivers,
especially those of the families Siluroidei and Characini, produce
peculiar sounds. The swimming-bladder is the principal organ
100 Miscellaneous.
employed. In the Siluroids the unossified portion of the swimming-
bladder is slightly elastic, in a nearly equal manner throughout its
whole extent; whilst in the Characini the elasticity depends espe-
cially upon flat bands or round cords in the wall. The swimming-
bladder acquires its greatest development as an organ of sound in
the Siluroids. In the species of the genera Platystoma and Pseuda-
roides it is divided by a longitudinal partition and by several trans-
verse partitions into a number of chambers or cells, which, however,
freely communicate with each other. In the genus Doras the
swimming-bladder presents numerous diverticula, divided internally
by incomplete septa into a great number of smallcells, In all these
fishes the transverse apophyses* of the two or three first vertebra,
and frequently a part of the arch of the first vertebra, are not only
bound to each other, but also to the posterior part of the cranium
and the apophyses of the first vertebra, by very strong elastic mem-
branes. The transverse apophyses of the second or third vertebra, and
sometimes of both these vertebrae, are shaped into the form of very
powerful springs t, and closely united to the swimming-bladder.
The sound is produced by the action of the muscles which are
inserted either directly in the swimming-bladder or upon the trans-
verse apophyses of the third vertebra. In the Characini the elastic
parts of the swimming-bladder are stretched in the direction of their
length by the contraction of the muscles; and the vibration that
results from this rhythmic movement is transmitted to the air con-
tained in the cavity of the swimming-bladder. In the Siluroids the
anterior portion of the swimming-bladder is drawn alternately
forward and backward by the contraction and relaxation of the
muscles, During these movements the air, in passing across the
incomplete transverse septa, sets the latter in vibration, and the
sound is produced. The height or rather the depth of the sound is
in direct proportion to the rapidity of the vibrations of the springs.
The fishes which I have been able to study in this connexion
belong to the genera Ageniosus, Doras, Platystoma, Pseudaroides,
Prochilodus, Chalcinus, Pygocentrus, and Myletes ; several of them
were observed living. None of these fishes respire by means of the
swimming-bladder. A memoir containing the details of these obser-
vations will appear in the ‘ Naturhistorisk Tidsskrift’ of Copen-
hagen.—Comptes Rendus, May 19, 1879, p. 1042.
* According to Weber (‘De auri et auditu hominis et animalium,’
p- 1, Lipsize, 1820) these apophyses, in the genus St/rws and in the
species of the family Cyprinoidei, serve to put the ear in communication
with the swimming-bladder. I cannot say whether there is an organ of
sound in the latter family, not having yet examined them in this respect.
+ According to John Miiller (‘ Archiy fiir Anat. und Physiologie,’
1842, p. 319), this apparatus, in the genera Auchenipterus, Synodontus,
Doras, Malacopterurus, and Euanemus, assists in locomotion by conden-
sing or rarefying the air in the swimming-bladder. Upon this interpre-
tation M. Moreau, in his excellent memoir on the swimming-bladder
(Ann, Sci, Nat. 6¢ sér.iv. Art. no, 8), has already expressed certain doubts,
the justice of which I am in a position to prove completely,

X.—On the Mode of Growth of Stromatopora, including the
Commensalism of Caunopora. By H. J. Carrer, F.R.S.
&e.
STRUCK with* the practical nature of Mr. Champernowne’s
remarks on “some Devonian Stromatoporide from Darting-
ton, near Totnes,” published in the Quart. Journ. Geol. Soc.
for February 1879, I lost no time in putting myself in communi-
cation with him on this subject, and having received, in reply,
a kind invitation to visit the “ Pit-Park Quarry” (whence
his specimens had been taken), I availed myself of the oppor-
tunity on the 8th of May last.
During our inspection of the quarry, as well as during the
short time I was with Mr. Champernowne, I learnt no less
from the former than from the latter, whose cautious observa-
tions, combined with his opportunities of obtaining practical
information, rendered his remarks very valuable in a scientific
point of view.
On my return to this place (Budleigh-Salterton) I washed
the specimens brought away from the Quarry, and dissected
them by fracture, section, and polishing, as far as such means
and such material would admit, whereby I learnt much more.
My general inference from our visit to the Quarry was that
Stromatopora was essentially a ‘‘reef-building”’ organism,
and that, like Millepora alcicornis in the West Indies, it grew
Ann. & Mag. N. Hist. Ser. 5. Vol. iv. 8
102 Mr. H. J. Carter on the Growth of Stromatopora.
profusely in its locality, not only entering and filling up the
open interstices of other calcareous organisms during their
growth, but enveloping their detritus (joimts and stems of
Encrinites, &c.), and, when not doing either of these things,
growing into large masses of itself. Thus, by cementing
every thing together after this manner, the great reef appears
to have been formed which is now known by the name of
“ Devonian Limestone.”’ This is not only evidenced by the
composition of the solidified strata generally, when cut and
polished, but more convincingly and particularly by a portion
of it in “ Pit-Park Quarry,” which, having undergone partial
decomposition, now yields up its contents even more sepa-
rately than probably they have ever been since they were
bound together by the ubiquitous Stromatopora.
In the first place, I could not help seeing how often Stroma-
topora had grown on Favosites ;. and on turning to the speci-
men which led me to the remarks on Cawnopora mm my
paper on the probable nature of the animal of Séromatopora
(‘ Annals,’ 1878, vol. 1. pp. 311, 312), I felt constrained to
fall back upon this coral; and I also saw that, although
perfectly right as regards the difference between the “ axial”’
and “tubulated”’ structure in Millepora alcicornis (ib. p. 316
&c.), this could not be applied to Caunopora.
Herein I was muci influenced by Mr. Champernowne’s
showing me what Dr. Duncan had pointed oyt to him, viz.
that the supposed genus “ Battersbya” of MM. Edwards
and Haime, who placed it among the Milleporide, consisted
of a coral the interstices of which were filled up with a
Stromatopora; so that, virtually, there was no such organism.
We next examined specimens of Syringopora, in which the
same thing was observed to have taken place. But why
should I recount more instances of this nature when I have
already stated that ‘ Pit-Park Quarry” bore evidence of
every thing, both living and dead, having been overrun by
Stromatopora (including Caunopora under this head) during
the formation of the “ reef.”
All this led me, on my return home, to again see what -
Baron Rosen had stated and illustrated of Stromatopora
Schmidtit, I then found that S. Schmidtit could not be
a species of Caunopora, as stated in my paper (J. c. p. 319) ;
and, on referring to Rosen’s account (p. 80), this was confirmed
by his statement that Roemer was “right” in considering
Caunopora placenta, Lonsdale, nothing but the tubes of a
“coral”’ surrounded by Stromatopora.
To this view I am now inclined to accede, as to the
presence of these tubes indicating that of an organism dif-
Mr. H. J. Carter on the Growth of Stromatopora. 103
ferent from the matrix in which they are enveloped, after
the manner of Battersbya &c., but not as regards an equally
“coral” nature of the tubes, as will be seen hereafter; and,
if this view be right, then, by eliminating Cauwnopora from
the Stromatoporide, much will be gained by the latter in
simplification. Still Rosen’s general division of the struc-
ture of the Stromatopore into “ curvilinear”? and “ recti-
linear’ coenenchyma will remain the same; and the remark
in my paper (/. c. p. 312), that in Caunopora I saw the same
kind of granulated curvilinear fibre as in the coral called
Battersbya, becomes intelligible.
That the tubes of Caunopora are adventitious or different
from the curvilinear coenenchyma of Stromatopora, which
generally accompanies them, is proved by their occasional
presence in another kind of Stromatoporoid ccenenchyma, 7. e.
in Stromatopora elegans, Rosen (vulg. “ Stagshorn” here-
abouts), of which I possess two specimens ; while, in support
of this, Mr. Champernowne states that the stromatoporoid
coenenchyma of Caunopora is ‘as variable as the Stromato-
pora itself is variable ;’’ add to this that the different kinds
of coenenchyma constantly occur without the tubes peculiar to
Caunopora.
Further, it happens that in a polished section of a specimen
of Caunopora from “ Pit-Park Quarry,” which Mr. Champer-
nowne gave me, the lower surface (which is in its natural state)
is terminal; that is, the tubes do not pass through it, while
at the bottom of the polished part, close to the angle it forms
with the “natural surface,” the tubes may be observed to
turn out of their vertical course and become united to a hori-
zoutal tortuous tubulation simulating that of the hydrorhiza
of hydroid zoophytes, which, under this aspect, appears to
form the whole of the ‘‘ natural surface ;” and hence the ends
of the tubes of the Caunopora do not project through this
matted structure, as in most cases where the fractured part
of the specimen has passed through the tubes themselves.
If this should be substantiated, then we can understand
how the tubes of Caunopora, for the most part, should be
without walls, ¢. e. appear as mere spaces, seeing that, while
one kind of Syringopora was probably a calcareous hydroid,
the tubes of Caunopora might, for the most part, have
belonged to a chitinous or flexible kind, which in fossilization
would only be represented as a mould made by the ccenen-
chyma of the Stromatopora. Still, as Mr. Champernowne
observes, “ crystallization, we know, acts, apparently, in the
most capricious manner, and it may be the cause of these
different aspects.”
8*
104 Mr. H. J. Carter on the Growth of Stromatopora.
Here I might observe that the infundibular structure of
Syringopora appears to be allied to the diaphragms produced
by the “annulation” (or circular constrictions of the tube)
which is such a very common feature among the flexible
Hydroids, and thus frequently appears in a modified form in
the tubes of Caunopora—the effect of such constrictions being
to force the coenosareal tube into the centre of the flexible
horny one, which in Syringopora geniculata, from the tubular
processes of the infundibula passing into each other, gets
beyond a mere constriction, and thus sometimes becomes a
continuous calcareous central canal.
The tubes of Caunopora are, for the most part, straight or
slightly flexuous, equal in calibre, unbranched and parallel in
their course, and, although hardly ever appearing otherwise
than in short fragments, were found by Mr. Champernowne,
in a weathered-out instance from “ Pit-Park Quarry,” to attain
1? inch in length; so that it may fairly be assumed that, if
it were not for their slightly flexuous course, they would be
found to be continuous throughout, 2. e. from their origin to
their termination. But it by no means follows that because
the main tubes pursued this course they were not often united
by smaller ones, after the manner of Syréngopora, from which
it becomes almost impossible to separate them in every respect
when all their structural varzetves are taken into account.
Seeking among the flexible Hydroids for one that would
afford analogous features, we find it in Tubularia indivisa,
which grows so luxuriantly on our coasts, of which the Rev.
T. Hincks (Hist. Brit. Hydroid Zoophytes, 1868, vol. i.
p- 115) gives the following characters of the polypary, viz. :—
“Clustered, simple, erect, without annulation, narrowed and
twisted at the base, horn-coloured, rising to a height of from
6 to 12 inches.” ‘The tubes are about 1-16th of an inch in
diameter, and seldom divide except near the hydrorhiza, which
consists of “twisted and interwoven tubes often agglomerated
together.” But then there are not only other species of Z'udbu-
laria which divide throughout much oftener, but one, viz.
T. bellis, which is annulated throughout (op. cit. Atlas,
fle 2X1, ):
Now such Hydroid Zoophytes, whether flexible or calca-
reous, if overgrown with Stromatopora, would represent Cauno-
pora; and if we require a similar instance of commensalism,
it is afforded in Stephanoscyphus mirabilis, which Prof. All-
man found on the south coast of France, and describes as
consisting of a horny sponge traversed by ‘a congeries of
tubes which penetrate the sponge-tissue and open on its sur-
a
face, united by a common tubular plexus towards the base.”
Mr. H. J. Carter on the Growth of Stromatopora. 105
Dr. F. E. Schulze, of Gratz, subsequently found this in the
Adriatic Sea, where the hydroid polyp &e. designated by him
Spongicola fistularis was found to be the denizen of several
different kinds of sponges; and his representation (Archiv f.
mikroskop. Anatomie, Bd. xiii. Taf. xlii. fig. 8) might, the
sponge being replaced by Stromatopora, pass for a specimen
of Caunopora with the tubes much branched,
Again, it should be remembered that in commensalism the
host is hardly ever without its guest; so that it becomes the
habit of the latter to dwell with the former even from the
commencement of life, and, while the guest may never be seen
without its host, the latter is occasionally seen without its
guest. In a beautiful preparation which Dr. F. E. Schulze
has just kindly sent me, the guest, viz. Oscillaria spongetia,
is already present in the embryo of Spongetia pallescens, which
it afterwards pervades throughout life (Zeitschrift f. wiss.
Zool. Bd. xxxii. p. 149, Taf. v. fig. 7). So that it is not
surprising that Caunopora, 1. e. the host and its guest together,
should be occasionally found surrounding Corals also together
in the way above mentioned.
I am aware that all but Roemer and Rosen (that is, all
English authors on the subject) have, from Lonsdale down-
wards, viewed Caunopora as a distinct species of Stromatopora ;
but I myself now cannot help, from the facts above mentioned,
regarding it as an instance of commensalism ; and in this I am
supported by Mr. Champernowne.
The fact, however, that Cawnopora may thus be found to be
a compound of two organisms does not invalidate what I have
stated respecting MJillepora alctcornis, in which there are dis-
tinct tubes among the Stromatoporoid coenenchyma rising
from an axial structure of a different form. Millepora alci-
cornis, too, overruns every thing in its way; thus, in the
British Museum there is a large Murex, together with reticu-
lated Gorgoniw, covered with it. Ellis notices that it is one
of the commonest corals in Jamaica, where it is principally used
for burning into lime (Nat. Hist. Zoophytes, 1786, p. 142),
and afterwards mentions a bottle that became incrusted with it ;
so that, as the branches coalesce between themselves, and
in like manner this species of JMillepora attaches to ztself
every foreign body that comes in its way, a reef-accumulation
may be thus produced, similar to that which was built up by
Stromatopora. By eliminating Caunopora, therefore, the
description of Stromatopora is not only more simplified, but
Millepora alcicornis and the Hydractinie are brought together,
which, as Mr. Champernowne observes, afford the best key
to a right understanding of what Stromatopora really was.
106 Dr. A. Giinther on a new Porcupine
Again, with reference to my statement, that in the sponges
the excretory canal-system commences in the ampullaceous
sacs (Wimperkérbe) (Ann. 1878, vol. i. p. 822), [have now
to modify this assertion ; for my figure of the pore-area in Grey-
ella cyathophora directly opening into an excretory canal
(Ann. 1869, vol. iv. pp. 192, 193, pl. vill. fig. 5, &e.), con-
firmed by that of Awos spinipoculum (ib. 1879, vol. ii.
p- 290, pl. xxv. fig. 4, &c.), shows at least that a commence-
ment in the ampullaceous sacs is not always the case, and
presents quite a new feature in the offices of the excretory
canals of sponges; although it does not alter the fact that
the system is partly excretory in the sponge, while the stellate
venation often appears without any aperture at all (Rosen,
Taf. xi. fig. 7), as the hydrophyton or proliferous organ in
Stromatopora.
Since the above was written I have seen C. F. Roemer’s
‘ Rheinische Uebergangsgebirge,’ 1844, in which, at p. 57, he
observes that Caunopora placenta, Phillips, is “ nichts An-
deres, als Stromatopora polymorpha von Syringoporen durch-
wachsen,” and, further, that the specimens from the Hifel,
the Silurian outliers of Mark Brandenburg and Silesia, toge-
ther with those of the Devonian Limestone are “ undistin-
guishable.”’
XI.—Description of a new Species of Porcupine from the
Philippine Islands. By Dr. A. GintuEr, F.R.S.
Brrore Mr. Everett left the Philippine Islands he obtained
at Puerto Princesa, in the island of Paragua, a specimen of a
small kind of Porcupine, which evidently is undescribed. It
is distinguished at the first glance by its small size and by
the shortness of its tail. In many respects it resembles ~
Hystrix crassispinis from Borneo, but is considerably smaller
and the quills are less thick. ‘The specimens sent by Mr.
Everett consist of the skin of a female which is nearly full-
grown, and of the perfect skeleton of a very old male. The
species may be called
Hystrix pumila.
All the upper and lateral parts of the body are densely
covered with flat, deeply grooved, flexible bristles of moderate
length. These bristles are gradually developed into spines
on the hinder part of the back, the shorter spines continuing
to be provided with a shallow groove above. The strongest
from the Philippine Islands. 107
quills are thicker in the middle than one of the incisors. Tail
short, the pediculated terminal quills small. Colour greyish
brown in front, the strongest quills black with a whitish base
and with scarcely any white at the extremity.. Lower parts
greyish white. Some white hairs near the front claws.

The skull is distinguished by the shortness of the nasal

the sides. Infraorbital opening rather wide. Ascending
ramus of the intermaxillary narrower than a nasal bone, and
not extending so far backwards as the nasals. The palatal
incision advances forward to opposite the middle of the hinder
molar. The outline of the masticatory surface of the molars
is almost circular in adult individuals.

being that of an old, the other (B) of a younger individual (in
which the fourth molar is still undeveloped).

the tail of this species is also indicated by a diminution
in the number of caudal vertebrae: there are only ten; and
the termination of the last shows that only one or two rudi-
mentary vertebre, if any, are missing. ‘The numbers of the.
other vertebre are the same as in LHystrix javanica, namely
7 cervical, 14 dorsal, 5 lumbar, and 4 sacral.

XIi.—Deseription of a new Species of Didelphys from Deme-
rara. By Dr. ALBERT GUNTHER, F.R.S.
Tne British Museum has recently received from one of its
correspondents in Demerara, the Rev. W. Y. Turner, a small
opossum, which resembles Didelphys crassicaudata in the
general form of the body, structure of the hair, and relative
length and hairiness of the tail, but which is only half the
size of that animal, and, besides, distinguished from all other
opossums by having eight incisors only in the upper jaw. It
seems to be undescribed, and may be named
Didelphys Turnert.
The muzzle is of moderate length and rather pointed ; ears
short, nearly naked, partially clothed with small hairs on the
inside ; fur of the head, body, and tail a little harsh, not
woolly; tail rather shorter than the head and body taken
together, with the basal third clothed with fur like that on the
body, the remaining portion with short hairs. Colour uniform
brown tinged with greyish, lower parts light brownish grey ;
hairs of the scrotum dark orange-coloured; the terminal two
thirds of the tail black, with white apex ; feet short.

Myrmecium, Goldf.
(Petr. Germ. p. 18.)
Cnemidium p. p., Goldf.
Epitheles p.p., From.
Myrmecium, ? Gymnomyrmecium, Pom.
Sponge small, hemispherical, spherical, or cylindrical, nar-
rowed below, shortly pedunculate, at the base with a smooth
or concentrically wrinkled dermal layer, which sometimes also
coats the whole of the sides. Vertex convex, with a round
osculum in the middle, serving as an opening to a narrow
tubular stomachal cavity, which traverses the whole sponge-
body vertically. There are also numerous small poriform
ostia distributed on the surface wherever it is not clothed with
the covering layer.
In the central cavity terminate rather stout radial canals,
which follow a curved course from without and below, and
are furcate in the vicinity of the surface. Their ostia are
generally placed in longitudinal series in the wall of the
central tube. Other straight canals penetrate into the sponge-
body obliquely inwards and downwards from the superficial
ostia.
The skeleton consists of a narrow-meshed tissue of rather
thin anastomosing fibres, usually composed of calcite, rarely
of silica. I have been unable to recognize spicules with
perfect certainty ; but certain parts of the calcite fibres appear
to me to contain three- or four-rayed stars.
This genus is distinguished from Corynella chiefly by the
fine skeletal fibres, the narrow central cavity, and the greatly
developed covering layer, which is always present and _fre-
quently envelops the sponge-body up to the vertex. It is
for the present not very sharply defined; but the Upper-Ju-
rassie species belonging to it bear so peculiar a stamp that
I could not resolve to unite them with Corynedla.

? Hreparimus, Lamx.
Hippalimeudea, From. (non Hippalimus, D’Orb., Rom. &e.).
Sponge mushroom- or umbrella-shaped, pedunculate ; ver-
tex with a wide funnel-shaped central cavity. The sloping
sides of the conical umbrella set with oscula. Lower surface
of the umbrella, stem, and wall of the central cavity smooth,
without oscula.
I know this genus only from figures, and am consequently
uncertain about its systematic position. Possibly it belongs
to the order Lithistidee.
The single species, /7. lobatus, Lamx., Exp. Méth. pl. Ixxix.
fig. 1, is from the Cenomanian of Villers in Calvados.
Lymnorea, Lamx.
Mamillipora, Bronn.
LIymnoreotheles, From.
Iymmnorea, Placorea, Pom,
Sponge nodular, consisting of verruciform, mamilliform, or
elobular individuals, which are grown together and covered
by a common, thick, and wrinkled basal epidermis. At the
vertex of each individual there is a simple, sometimes radiate,
and not very deep osculum.
Of the typical species of this genus I possess only insuffi-
cient material, which gives me no certain information as to
the nature of the oscula and the depth of the stomachal cavity.
In a specimen from Ranville [ have made sections of several
of the round heads: the shallow oscula, into which a number
of radial canals opened, then soon disappeared; but there re-
mained, instead of them, upon the cut surface, some scattered
round sections of fine vertical canals; and that these traversed
the whole sponge-body appears from the fact that on cutting
through the base of the common peduncle a bundle of fine
canal-sections was visible in the centre. The oscula conse-

quently appear to be continued downwards into simple fine
tubes.
The only species which certainly belongs here occurs in
the Middle Jura :—

Stellispongia, Asterospongia, Desmospongia, Didesmospongia, Cerio-

Sponge simple or, more frequently, composite. Individuals
globular, semiglobular, clavate, or cylindrical; stock often
nodular, clothed, almost always at the base, and sometimes
also on the sides, with a thick, wrinkled, dermal layer. Ver-
tex convex, with a shallow radiate osculum, into which open
a larger or smaller number of efferent canals. The round
ostia of the latter are situated partly at the bottom, partly on
the sides of the osculum; the former are connected with
vertical, the latter with radial canals. The uppermost radial
canals are frequently open, and then form more or less im-
pressed radial furrows. Over all the rest of the surface of
the sponge-body, so far as it is not covered with epitheca,
there are smaller ostia, connected with vertical or oblique
incurrent canals.
The anastomosing skeletal fibres are generally of consider-
able thickness.
I have limited D’Orbigny’s name Stellispongia to those
calcareous sponges which are characterized by radiate oscula
into which vertical and radial canals open, and by numerous
smaller ostia on the surface. ‘The round orifices at the bottom
of the oscula have previously often been overlooked, but they
are wanting in no true Stellispongia.
Fromentel’s genus Hnaulofungia is founded upon an erro-
neous observation ; for upon the typical species (4. corallina)
itself the ostia on the surface are very distinctly developed.
The species belonging to this genus are from the Trias
Jura, and Cretaceous.

Paleojerea, Laube.
Sponge simple, or more frequently compound, tufted or com-
osed of verruciform individuals standing on a common base.
Individuals distinctly separated, cylindrico-clavate or semi-
globular; vertex with a shallow, sometimes radiate osculum,
into which a great number of round ostia of vertical tubular
efferent canals open. Surface porous, naked, or the base and
sometimes also a part of the sides clothed with a dermal
layer.
The calcareous sponges belonging to this genus have
hitherto been described under the names of Sparsispongia, °
vemospongia, or Paleojerea. Under the name of Sparsi-
M. K. A. Zittel on Fossil Calcispongie. 127
spongia, D’Orbigny understood chiefly certain Stromatopore
furnished with pores, as well as some calcareous sponges from
the Upper Cretaceous, which were placed by Fromentel under
Tremospongia. Of all the species of Sparsispongia mentioned
in the “‘ Prodrome,” not a single one belongs to the present
genus, whilst our diagnosis of Sestrostomella embraces most
of the Sparsispongie and a part of the Tremospongie of Fro-
mentel. Fromentel distinguishes these two genera principally
according to the absence or presence of an epitheca. But that
so unessential and inconstant a character cannot be employed
for the discrimination of genera among the sponges any more
than among corals, is most clearly seen in the fossil Calci-
spongie, among which, on account of this difference, we
should have to place in different genera forms which agree
perfectly in all other essential characters.
As Fromentel has applied D’Orbigny’s names Tremospongia
and Sparsispongia quite arbitrarily, and D’Orbigny himself
characterizes them by very indefinite and, in part, erroneous
diagnoses, I regard it as advisable to drop both names.
The genus Sestrostomella occurs from the Trias up to the
Cretaceous.

BLASTINIA, Zittel.
Achilleum p. p., Goldf.
Actinospongia p. p.. Pterosmila p.p., Pom.
Astrospongia p. p., Etal.
Tetrasmila p. p., From.
Sponge bud-like or clavate, simple, gradually narrowed
below into a peduncle. Vertex with radially converging,
more or less deep constrictions, which are continued over half
or more of the height of the sponge. The lower half is coated
with a wrinkled dermal layer; the upper half naked, rough,
and porous. Skeleton consisting of vermiform interwoven
fibres. Central cavity, ostia, and canals wanting.
This genus in many respects resembles Stellispongia, but
is easily distinguished by the want of an orifice furnished with
tubes in the vertex, and of a canal-system.
Pomel refers the typical species (Achillewm costatum, Goldt.)
to Actinospongia, D’Orb.; but in A. ornata, upon which
D’Orbigny had founded his genus, he remarks the presence
of ‘perforant proctides’’ both in the furrows and on the
coste of the vertex. According to these characters, Actino-
spongia, D’Orb., should be identical with Stellispongia.
I believe also that Spongites alatus, Quenst., must be re-
ferred here, as the structure of several specimens from the
Blauthal exactly agrees with that of Achilleum costatum.
But whether Certopora alata, Goldf. (Taf. xi. fig. 8), is iden-
tical therewith, I regard as doubtful, notwithstanding the
external resemblance. ‘The state of preservation of the silici-
fied specimens from Franconia permits no examination of the
microstructure ; and from the general habit I should regard
the small-winged bodies which Fromentel refers to the genus
Tetrasmila, and Pomel to Pterosmila, rather as Hydractinie
or Bryozoa. Now that M. Steinmann* has demonstrated
that Thalamospongia at least belongs to the Hydractiniz, the
whole family Porosmiline of Pomel, with the genera Zhala-
mospongia, D’Orb., Porosmila, From., Heterosmila, Pom.,
Ceelosmila, Pom., Pterosmila, Pom., and Cladosmila, Pom.,
ought also probably to be removed to the same group.
All the species are from the Upper Jura.

SYNOPELLA, Zittel.
Tremospongia p. p., Sparsispongia p. p., D’Orb.; From.
Tremospongia, Orosphecion, Aplosphecion, Pom.
Sponge composite, rarely simple, hemispherical or nodular.
Upper surface plain, convex, or warty, with irregularly scat-
tered oscula, which are formed by the separated openings of
two or more large excurrent canals. Besides these oscula,
the surface is furnished with small ostia of fine incurrent
tubules. Base, and frequently also the sides, coated with a
thick wrinkled dermal layer. Skeletal fibres coarse.
This genus is difficult to define sharply from Stellispongia
and Sestrostomella, although the typical species bear a pecu-
liar stamp. Ifthe oscula are radiated by radial canals, as
now and then occurs, the distinction from Stellispongia is
difficult ; if, on the other hand, the roundish heads project
more definitely from the mass, transitions towards Sestrosto-
mella are produced. ‘To the present genus I refer only nodu-
lar forms in which the individuals are not sharply defined,
but amalgamated with each other.
The species are distributed through the different horizons
of the Cretaceous formation.

vertex, coated with a dense, smooth dermal layer, in which
there are rather large, round or distorted, frequently margined
oscula; these are either quite shallow or sunk into the sponge-
mass in the form of a funnel, often furnished with canal-ostia
at the bottom. The skeleton consists of coarse anastomosing
fibres. Canal-system indistinctly developed.

Sponge cup-, funnel-, or leaf-shaped ; in the last case the
thick-walled leaf always bent or folded. Upper surface
=inner surface) usually smooth, with very small oscula or
only simple pores. Outer surface rough, porous. Canal-sys-
tem deficient, or consisting of fine tubes, which penetrate from
both surfaces into the wall. Skeleton consisting of anasto-
mosing vermiform fibres, which are entirely composed of
simple bacillar spicules.
As Mr. Sollas has so admirably described (Quart. Journ.
132 M. K. A. Zittel on Fossil Calcispongie.
Geol. Soc. 1877, p. 242) the microstructure and characters of
the organization of Pharetrospongia Strahant, I extend this
name to a number of calcareous sponges of similar structure
and form which have hitherto generally been referred to
Cupulospongia, D’Orb., or Cupulochonia, From. Under these
names, however, the most different Hexactinellide, Lithistide,
and Calcispongiz have been thrown together; so that it does
not seem advisable to maintain either of them.
I have somewhat altered Sollas’s diagnosis, and associated
with the typical species (P. Strahanz), which consists of a
folded leaf, a series of cup-shaped sponges which agree in
their other essential characters. The genus has thus certainly
attained a wide extent and a somewhat vague limitation; but
some unsuccessful attempts to break it up into several
genera have led me constantly back to the union of all the
forms cited below. Very frequently the state of preservation
causes notable differences which did not originally exist.
Thus, probably, all the species in which both surfaces are of a
rough and porous texture must have lost the smooth thin
epidermis, which is so beautifully preserved in certain speci-
mens from Farringdon, Essen, and Maestricht.
The development or the absence of canals depends, on the
one hand, upon the size of the oscula and ostia, and, on the
other, upon the coarser or finer meshes of the skeletal network.
In Cupulospongia farringdonensis, for example, there is a
double system of efferent and incurrent canals, whilst other
species are entirely destitute of canals.
If we give the genus Pharetrospongia the increased exten-
sion proposed by me, it contains species from the Trias up to
the uppermost Cretaceous.

special oscula or canal-openings. Skeleton consisting of a
coarse-meshed net of very thick, curved, anastomosing calca-
reous fibres, which sometimes coalesce to form regular lamelle
and vesicles, and among which the circulation of water took
place without any special canal-system.
This genus is distinguished trom Pharetrospongia by its
thick skeletal fibres, the complete absence of a canal-system,
and its very thick wall.

also composes the interior of the sponge-body. The circula-
tion of water could only take place in the interstices of the
skeleton.
In this genus I have been unable to detect spicules in the
calcareous fibres. All the thin sections which I have prepared
of specimens from St. Cassian or from the Seeland Alp ex-
hibit a crystalline-radiate structure.
By Laube several true Bryozoa were united with Letofun-
gia, Cribroscyphia, and Actinofungia; and Pomel also refers
a true Bryozoan (Catenipora spongiosa, Klipst.) to Aulaco-

fibrous sponges by their tubular structure.

Sponge simple, cylindrical or clavate, narrowed below, with
a wide tubular central cavity extending to the base. The
wall consists of hollow radial cones, placed in layers one
above the other, with their bases towards the central cavity
and their apices directed outwards. These hollow cones,
opening inwards, produce, on the wall of the central cavity,
numerous ostia, arranged in longitudinal rows, and leading
into the hollow cones. As the latter are narrowed outwards
and terminate in a truncated head, conical interspaces, but
pointed inwards, are formed between; and if both the hollow
cones and interspaces are filled with rock matter, it appears
Mr. G. E. Dobson on a new Species of Vesperugo, 135
as if the wall were furnished with two kinds of radial canals,
one set opening into the central cavity, while the others
commence about the middle of the wall and widen outwards.
The skeleton appears to be composed chiefly of tri- and
quadriradiate spicules ; I have, however, never succeeded in
distinctly displaying their form in thin sections.
I have no hesitation in referring this elegant genus to the
Sycones. The whole external form of the cylindrical sponge-
body, its construction of radial tubes, the numerous serially
arranged ostia on the wall of the central cavity, and, finally,
the mesh-like interspaces on the outer surface agree in a
remarkable manner with certain living Sycones. It is, how-
ever, impossible to assign it precisely to a place among the
recent genera, on account of the imperfect preservation of
the skeletal spicules.
‘The typical species has been well figured by Goldfuss
(Taf. i. fig. 10) as Scyphia punctata. It occurs, not very
abundantly, in the middle sponge-limestone of the White
Jura. The skeleton almost always consists of calcite, and
shows indistinct spicular structure. Rarely also specimens
with a silicified skeleton occur; and one of these must have
been taken by O. Schmidt for his figure (Atlant. Spong.
Taf. i. fig. 21). The fragment probably shows the surface of
the wall of the stomachal cavity with the ostia of the radial
tubes, which stand in regular rows, and thus somewhat
remind us of the Hexactinellide. That O. Schmidt indicates
canals in the skeletal fibres is due to an illusion, at least if the
figure in question belongs to Scyphia punctata.
In Quenstedt’s ‘ Petrefactenkunde Deutschlands’ there are
good figures of Scyphia punctata (Taf. cxxxi. figs. 24-27).

Amost all the zoologists who have studied the parasitic
Cirripedes belonging to the group Suctoria have been induced
also to pay attention to certain Isopod Crustacea of the family
Bopyride, the history of which is intimately bound up with
that of those animals. This was my own case when, in 1873,
I commenced my researches upon Sacculina carcini. In fact
this parasite itself bears a parasite, Cryptoniscus larveeformis,
upon which I have already published some preliminary re-

marks*. In order to elucidate some doubtful points in the
degraded organization of the Cryptonisc’, I was obliged to
have recourse to the examination of other Bopyride of less
anomalous structure. I have thus collected materials of con-
siderable importance upon this family of Isopods. But most
of these animals are of great rarity; and the difficulty of
tracing their embryogeny is also very great—a single female
containing a great number of ova, it is true, but all in the
same stage of development. Hence I have not yet been able
to bring the monograph which I have projected to a point of
perfection sufficient for the commencement of publication. I
will now, however, at least make known some results obtained
in the case of a very sparingly distributed genus, the genus
Entoniscust. I hope by this means to hinder from useless
researches those who might be tempted to attack the same sub-
ject, and to furnish some data which will be made use of
hereafter for a more general treatise f.
The genus Entoniscus, established by Fritz Miiller in
1862, includes animals which had been met with by Cavolini
as long ago as 1787. Cavolini had observed Sacculinw upon
several species of crabs ; and he regarded these parasites as the
broods (ponte) of a small species of Cyclops grafted by the
mother upon the tail of the Brachyurans. After bringing
forward his observations upon this subject he adds :—
“ Besides the Cyclops which we have just described, there
is in the sea another insect which fixes its brood upon the
body of our crabs, but in a manner much more inconvenient
for those animals. It is, in fact, in the very midst of their
viscera that the eggs are attached. Hitherto the Depressus§

§ It is impossible not to recognize Grapsus varius in the fine descrip-
tion given by Cavolini of his Granchio depresso :—
“Questo granchio é copiosissimo per gli scogli del nostro cratere, e
sembra godere piuttosto di stare in secco, massimassime quando, pel
calor della state, le acque presso i lidi si riscaldano, o si albanano: su di

alone has appeared to me to be attacked. On the side of the
stomach, at the point where the liver is situated, one sees a
very voluminous mass, of a more or less yellowish or leaden
colour, according to the degree of its maturity, occupying the
place of the ovarian branch of the crab. This body pushes
through the ribs of the carapace, and thus insinuates itself
into the branchial cavity. It is not difficult to separate it
from the crab, to which we find it to be attached by cellular
tissue ; the anterior part of this ovarian body, that which is
placed in the viscera, becomes mature first, and consequently
it is much more dilated, a, while the other, 6, which 1s situ-
ated between the ribs, is still immature, and retains the im-
pression of these solid parts. The ovarian sac is formed of a
transparent tissue, and contains in this state the graduated
series of the development of the ova which it encloses: the
most mature are in a, and are visible to the naked eye only
as a granular substance; in the figure, however, they have
been drawn a little larger, in order to avoid confusion; the
less advanced ones are in 6. Seen by the microscope, the
latter are of a rounded form, ¢; those which are a little less
immature are figured at m; those which most nearly approach
maturity are uniform and emarginate, as at 2; lastly, the
hatched embryos have the form represented in 7, and run in
all directions in the drop of water placed under the lens of the
microscope. These insects have the body divided into a great
number of rings, the first of which bears two eyes; the tail is
bifurcate ; and the last joint of the first four pairs of feet is
claviform.
“ This insect belongs to the race of the Oniscus squilliformis,
very well described by Pallas; it presents a certain analogy
with the species described under the name of Oniscus locusta*
by that illustrious naturalist, a species very frequent in the
organic rubbish thrown up on the sand and bathed by the
sea in its movements to and fro; it is our sand-flea. How-
ever, the species which is developed at the expense of the
blood of the crab is much smaller than this sand-flea. It is
true that I have been able to see this insect only at the
scoglio fin ché in mare precipiti, o vero in una prossima buca si rimpiatta :
percid dai nostri pescatori si chiama Granchio spirito.” '
In the same memoir Cavolini describes and figures:—1, a Gregarina
parasitic on the Grapsus, which he calls Tzenia 5 2, the z0ea of the Grapsus
(pl. ii. figs.7,8, & 9). As early as 1768 Slabber, for his part, had discovered
the metamorphoses of the i aes ; but it was only in 1823 that Vaughan
Thompson generalized these observations, which had been completely
forgotten. STO, tpl oe

moment of its exclusion; but the size of the eggs which I
have found attached to the feet of our sand-flea has taught me
that the young of this latter must be of a size greatly superior
to that of the insect which I have described and drawn issuing
from the ovaries contained within the body of the crabs.
“¢ Now in what way does the mother Oniscus introduce her
brood into the body of the crabs, when this body is completely
defended by a hard and crustaceous skin? Here | must
argue by conjecture, but by necessary conjecture, until it may
be possible to obtain ocular proof of the fact of this penetra-
tion. We have already described above the two cavities
situated one upon each side of the body of the crab, and in
which the branchizs move. The water euters and issues from
these by two apertures provided with valves, and situated at
the sides of the mouth in front of the lateral commissure of
the upper portion with the lower portion of the carapace. ‘The
anterior part of these cavities is formed of a delicate mem-
brane which clothes the viscera of the crab. We can therefore
understand with the greatest facility that the mother insect
penetrates with the water into such a cavity, and, perforating
its delicate wall, introduces her brood into the body of the
crab; the mother insect enters then in the same manner as
the ova of Serpule or of oysters, which I have frequently
found hatched or fixed against the ribs which exist in the
above-mentioned branchial cavity.
‘“‘ We have, therefore, in the crabs two cases of grafting of
animal parts; the brood of these two insects, which need for
their development juices elaborated in an animal body, could
not be brought to its term by the mother. Nature has taken
upon herself to furnish it with a fat and devoted nurse,
namely the body of our crabs. The mother makes a small
aperture in the skin which covers the intestine; sometimes
she fixes her brood to the outside, sometimes introduces it into
the body of the crab, enclosed in a membrane performing
the part of a placenta; and, as the eggs contained in this
membrane are animated and tend to develop themselves, it is
certain that the canals of this ovary are suckers absorbing the
liquids of the vessels of the living crab. By imosculating
with these latter and forming anastomoses with them, they
constitute a system continuous between the living body of the
crab, and another body, likewise living, which tends to com-
plete its evolution. In point of fact, a foreign foetus has
become the actual progeny of the crustacean, and has deve-
loped itself upon this animal in the same fashion as, among
the Mammalia, the abdominal foetuses are developed nearly as
they would be in the uterus, which is their normal and true

place of abode. If in a plant we make an incision and
introduce into it a living branch of another plant, there is
produced a graft by inosculation and union (raccordement)
of the vessels; exactly the same thing takes place in our
anunals.
“T do not know whether, hitherto, any animals which
graft themselves have been known. It seems to me that the
opposite of what I have just indicated had rather been
observed ; it had been seen that the eggs of one animal depo-
sited in the body of another animal produce tumours, which,
by bursting, form regular wounds. ‘This is the case with
those flies which lay their eggs under the skin of cattle, in
their nostrils, or their intestines, and whieh thus occasion a
tumour, and afterwards a sort of blister, the matter from
which nourishes their progeny *. Certainly the two para-
sites of the crabs just mentioned are rather grafted animals
than animal galls. ‘These latter are met with only in plants
attacked by animals. The egg of an insect deposited upon a
plant becomes soaked with the juices of the latter and grows
at its expense; but it is not strictly correct to say that the
canals of the egg anastomose with those of the plant and
become continuous with these latter ’’ .
It is evident, from Cavolini’s description and the figures
which accompany it, that in this case, as in that of Sacculina,
the supposed ovigerous sac is nothing but a crustacean de-
graded by parasitism; and the form of the young enables us
to recognize immediately that we have to do here with an
Isopod belonging to the group Bopyride. The few errors of
detail which exist in the description of the larva or of the
adult animal will be referred to hereafter. They cannot,
however, in any way modify this first conclusion. As will
be seen, these observations of Cavolini were very remarkable
if we consider the period at which they were published.
Unfortunately, in this question of the Bopyride, as in that
of the Suctoria, the bibliography is complicated in a regret-
table manner; the very great difficulty of bringing together
the original memoirs, often written in languages and published
in repertories which are but little known, causes one to con-
tent one’s self with quoting them from imperfect abstracts or
unfaithful translations. Hence one has several times taken

the trouble to demolish errors which did not exist in the
authors incriminated, and to rediscover truths which had long
been known
Thus, quite recently, in his interesting memoir on the
genus Cryptoniscus, P. Fraisse (2, p. 41) *, giving an analysis
of the memoirs of Cavolini, makes the Italian naturalist say
that it is very difficult to separate the Hntoniscus (the sup-
posed ovigerous sac) from the viscera of the crab. It is
evident that if Fraisse had had the text of Cavolini before
him he would not have translated ‘‘ questo corpo non é diffi-
cile separare”’ by “er sagt (Cavolini) dass er sehr schwer zu
trennen sei.”
I am equally unable to understand why Fraisse (/. ¢. p. 41)
reproaches Steenstrup with having falsified the sense of Cavo-
lini’s observations, saying that the Isopods observed by the
latter were in the Sacculina and not nm the body-cavity of
the crabs. The following is, in fact, the very judicious
appreciation, given by Steenstrup, of the facts observed by
Cavolini :—
“ Among the excellent observations,” he says, “ contained
in the valuable memoir of Cavolini, we find figured a very
curious mass of irregular form entirely filled with more or
less developed ova. ‘This mass was found in a crab ; by one
of its extremities it was fixed to the inner stomachal wall; by
the other it was fixed between the two partitions which bound
at the sides the segments forming the thoracic cavity of the
erab. In fig. 18, m,n, Cavolini has represented ova taken
in the mass in various stages of development ; in fig. 18, 77,
he has figured two young animals at the moment of their
issuing from the egg. Cavolini compares these young ani-
mals to the Oniscus squilliformis described by Pallas, and
designates them by that name. It is impossible not to recog-
nize in the description and drawing of these embryos a form
very nearly allied to the Lirtope of Rathke, so near that one
can hardly separate it therefrom ; one is consequently led, in
spite of one’s self, to a comparison with the larve: of Bopyrus.
The form of the young therefore shows us that this mass
filled with ova is, in all probability, nothing but a degraded
crustacean parasite, and even an animal of the family Bopy-
ride ; only the animal is still more deformed, and, one might
say, more monstrous than any other type of Bopyride, and even
then Peltogaster and Pachybdella. It is more than an Epi-
zoon; it is an Hntozoon, a sort of intravisceral worm, since,
like the singular Gasteropod (H’ntoconcha mirabilis) disco-

vered by Johannes Miiller in Synapta digitata, it is also
solidly attached to an internal organ.”
It is clear from this passage that Steenstrup perfectly
understood the general relations of the Hntondscus to the crab.
Instead of referring to the Danish text, or to the German
translation of Creplin, which is very correct, Fraisse has no
doubt spoken of Steenstrup’s work only from what Lilljeborg
says of it. The latter (4, p. 291, ‘Annales ’) has, in fact, con-
founded the Hntoniscus observed by Cavolini with the Liriope
(now Cryptoniscus) described by Rathke; and he has, moreover,
very wrongly ascribed the same confusion to Steenstrup.
Even the learned carcinologist Spence Bate has not been
able to keep himself clear of several errors in the citation
which he makes of Cavolini’s memoir*, in connexion with
the genus Cryptothiria, Dana. He says:— Cavolini first
described and figured two different crustaceous animals (one
of which he doubtingly referred to the Oniscus squilliformis
of Pallas) which he had found parasitic within a sac attached
to the tail of a crab belonging to the genus Portunus or Car-
cinus.” ‘There are, as will be seen, nearly as many inac-
curacies as words in this short reference.
The first and only zoologist who, since Cavolini, met with
parasites of the genus Hntoniscus was Fritz Miiller, who
appears not to have known the observations of the Italian
naturalist. It was in 1862 that Fritz Miiller formed the
genus Hntoniscus for an Isopod crustacean which he had met
with in the visceral cavity of a Porcellana of the coast of
Brazil, and which he named Hntoniscus porcellane f.
In 1871 the talented zoologist of Desterro made known a
new species of the same genus (Hntoniscus cancrorum), a
parasite of several species of Xantho.
Besides these two species, Fritz Miller has also met with
Entonisct under the following circumstances :—
1. In a small species of Porcellana which is found rarely
among the Sertularians and Bryozoa upon the rocks (a single
female of Hntoniscus which could not be studied, so that it is
impossible to assert that it belongs to the species parasitic on
the common Porcellana).
2. In a Porcellana named by Fritz Miiller Porcellana
(Polyonyx) Creplinti. It is allied to Porcellana biangulata,
Dana (Polyonyx, Stimps.), and usually occurs in pairs in the
tubes of Chetopterus. Only three times did Miiller meet with
* «British Sessile-eyed Crustacea,’ vol. ii. pp. 262 & 264.
+ According to F. Miiller this species of Yorcellana, of a blackish-green
colour, is excessively common under stones at Desterro. (Five per cent.
of these crustaceans harboured the parasite.)
144 M. A. Giard on the Genus Entoniscus.
isolated individuals—once a female, twice a male. Each of
these three individuals harboured an Entoniscus, whilst none
were ever found in the paired individuals. Fritz Miiller con-
cludes from this that the presence of the Hntoniscus, like that
of the Rhizocephala (Suctoria), superinduces sterility in the
animal infested, whence the abandonment of the latter by its
partner.
The Entoniscus of Porcellana Creplinii differs from that of
the ordinary Porcellana by the colour of the ovaries and the
form of the ovigerous lamellee.
3. Iu an Acheus living under rocks among Bryozoa and
Ascidia; a single couple of Hntoniscd; the male, which is
very characteristic, allows it to be affirmed that this species is
distinct from /. porcellane and LE. cancrorum.
This, therefore, makes at least four, and perhaps five, dis-
tinct species of this singular genus, all inhabitmg a small
corner of the Brazilian coast.
It would be very odd if a group of parasites, living upon
animals so widely distributed as the Decapods, were localized
in so small a space. It may be asserted, without fear of
deceiving ourselves, that, when they are more carefully sought
for, the species of the genus Hntonzscus will soon be met with,
more or less, everywhere.
It was with this idea that, during a residence of several
weeks that I made at the Pouliguen (Loire-Inférieure), I care-
fully examined many Decapods of that interesting locality ;
and I was especially urged to this investigation by the ex-
treme abundance, in the locality, of Grapsus varius, which I
knew had furnished Cavolini with the first species of the
genus Entoniscus *,
II. BioLoGgy AND ANATOMY.
The Grapsi collected in the small bays formed by the very
broken coast of the Pouliguen on the side of Penchateau are
very frequently infested by an Lntoniscus which may be
easily recognized as identical with that described by Cavolini,
and which, for that reason, I propose to name Hntontscus
Cavolinit.
The parasite is met with in both the males and the females.

belonged to the male and one to the female sex. But I have
learned from my investigations of the Rhizocephala that such
statistics, to be of any value, must be founded upon hundreds
of individuals collected in the same locality. Now my Grapst
came from various parts of the coast ; and I have examined, at
the utmost, two hundred individuals. I believe we may esti-
mate at one in thirty the number of crabs which bear the
parasite *,
Sometimes one finds two Hntonisc? in the same crab; and
in this case one of them has hampered the growth of the
other, which is a favourable circumstance for the observation
of intermediate stages, always rare among’ parasitic animals,
in consequence of the rapidity of.the retrogression.
Entoniscus Cavolinii, like the species studied by Fritz
Miiller, is enclosed in a fine membrane in continuity with
that which lines the inner surface of the branchial cavity of
the crab. It is placed between the liver, the stomach, and
the heart of its host. Generally the head is concealed among
the hepatic ceeca, and in part hidden under the anterior ovi-
gerous sac; the tail is recurved upon the ventral part, and
passes under the heart of the crab. The parasite is sometimes
on the left, sometimes on the right side of its host, most fre-
quently on the left side (three times more frequently) as it
seems to me.
The general form is rather difficult to describe ; moreover
it varies according to the age and position of the parasite.
We have represented it (Pl. X. fig. 1), as accurately as pos-
sible, from a living individual twisted upon itself. The
colour also varies according to the state of development of the
ova with which the animal is almost entirely surrounded ; it
is straw-yellow when the ova are but little advanced; at
maturity it acquires the lead-grey tint so well observed by
Cavolini. This tint is due to the formation of a peculiar
pigment in the embryo. 1
We have represented in Pl. X. fig. 2 the same individual
untwisted in such a manner as to bring the head into its
normal position. In this figure the walls of the incubatory
cavity and the abdominal plates are supposed to be removed,
* It is remarkable that none of the Grapsi that I have examined bore
a Saceulina. Fritz Miller remarked a frequent coexistence of Entoniseus
porcellane and Lerneodiscus porcellane. My zealous collaboratewr, J.
Prié, whose attention I had called to this point, has also never met with
Sacculina Benedenit. Moreover the Suctoria seem to prefer calm and
slightly impure waters ; they are much more frequently found upon the
various Decapods of the Bay of Penbron, at the Croisic, than on the
same crabs collected on the open shore of Pouliguen.

so as to show the real form of the body, composed almost
exclusively of the ovary and the digestive tube.
The incubatory chamber is composed of an anterior ventral
cavity communicating laterally with two latero-anterior cavi-
ties. Besides these three cavities, which are in communica-
tion, and form, so to speak, a trilobate cavity, the whole
dorsal part also presents a vast incubatory chamber, bilobed
posteriorly, and falling laterally in two folds, which meet
upon the ventral line when they are filled with ova.
These various parts are more clearly visible in the animal
before it is completely transformed into the stage represented
by Pl. X. figs. 3, 4*. We then see distinctly the trilobed
ventral cavity and the two chitinous crests of the ventral
border of the dorsal chamber.
This curious arrangement of the incubatory chambers is
very different from that indicated by Fritz Miiller in the case
of FE. porcellane and E. cancrorum. The first of these two
species presents thoracic plates which only differ from the
ordinary plates of the Bopyridee by their much greater deve-
lopment and fringed appearance. The second certainly pre-
sents an anterior ventral incubatory chamber ; but this chamber
appears much more reduced than in £. Cavolinii, and does
not seem to communicate with the dorsal part of the para-
site.
The terminal portion of Hntoniscus, or that which corre-
sponds to the abdomen of the other Isopoda, is most frequently
recurved towards the ventral side of the parasite. At the
dorsal part of the first segment of this abdomen we see the
heart beating, which has never appeared to me to form a
hernia as in Hntoniscus porcellane.
The ventral portion of the abdomen bears five pairs of
folded and undulated lamellar appendages, corresponding to
the five pairs of ramified appendages of the abdomen in Jone.
These appendages decrease in size from the origin of the
abdomen to the extremity of the body; so that, apparently,
the first pair forms two large lateral tufts, and the last four
pairs a median posterior tuft, equivalent to each of the first
two. The last pair of appendages, however, are not very
visible, and are formed by a simple fold of skin on each side.
The body terminates in a triangular expansion presenting
two dorsal folds. ‘There does not appear to be an anus, which
is explained, as we shall see, by the arrangement of the diges-
tive tube.
* These figures relate to 2. Moniexit, but, for the point now before us,
they may equally apply to E. Cavohinn.
M. A. Giard on the Genus Entoniscus. 147
The lamellar appendages of the abdomen of our Zntoniscus
greatly resemble those which Fritz Miiller has described and
figured in EH, porcellane. But in the latter the fringed
lamin are situated beneath the thoracic segments, and the
abdomen is occupied by sabre-shaped feet.
In Entoniscus cancrorum Miiller found fringed abdominal
folds ; but these folds, much less developed than in H. Cavo-
“init, form, on each side of the abdomen, an undulated con-
tinuous border, which does not extend so far as to the terminal
part of the body.
From this point of view also, #. Cavolinii therefore differs
considerably from the species hitherto described.
The head, of which we speak last of all, because, of all the
external parts of the animal, it is the least visible at the first
glance, is concealed beneath the folds of the ovigerous sac,
and presents the form of a double sphere (PI. X. figs. 2, 5).
The anterior part, in which the mouth is situated, is furnished
with two lamellar folds ; we find no trace of antenne; and,
by its internal organization, this head should rather have the
name of cephalogaster.
When we free the parasite from its ovigerous sacs and the
ova or embryos which they contain, we obtain a body of a
pretty constant form, composed in great part of the ovary and
the digestive organs of the Hntoniscus.
The ovarian body presents four lateral prolongations, two
anterior and two posterior (Pl. X. fig. 2), which are directed
from above downwards, towards the ventral part of the Ento-
niscus. We distinguish besides, also on the ventral part, two
or three pairs of much smaller eminences, which, with the
preceding, perhaps represent the traces of the thoracic feet
which have disappeared. Vestiges of these organs are still,
in fact, to be seen upon the less degraded animal in the stage
represented by figs. 3, 4.
On the dorsal part we observe two long median protu-
berances slightly bent from behind forwards. The posterior
is the longer one.
All these prolongations remind us of those observed in
an animal allied to Hntoniscus, namely Cryptothirta balani
(Hemioniscus, Buchholz), of which I have been able to exa-
mine several individuals collected at Wimereux, in the inte-
rior of the Balanus balanoides which cover the Tour de
Croy.
Tt is well known that, in certain species belonging to high
groups, parasitism often recalls peculiarities of organization
which are only to be met with in the larvee of the other species
of the same group. ‘These phenomena of reversion to the
148 M. A. Giard on the Genus Entoniscus.
atavic type by parasitic retrogression have frequently led
astray the zoologists who busy themselves solely with taxo-
nomy, and sometimes even embryogenists. Starting from
this idea, one might be tempted to compare the singular dorsal
processes of Hntoniscus with the analogous protuberances
which are observed in a great number of Crustacea in the
zoéa-stage. It is a comparison which naturally occurs to the
mind; and I thought it necessary to indicate it in my prelimi-
nary communication upon the genus EHntoniscus. I have
since reflected that more or less similar protuberances occur
in a great number of parasitic Crustacea belonging to inferior
types, notably among the Copepoda, where evidently they
cannot have the same significance. Hence, while calling
the attention of zoologists to the remarkable constancy of
these appendages in Hntoniscus Cavolinii, I do not venture
to pronounce in so affirmative a manner upon their true mor-
phological value. /
If we pass to the internal anatomy of the Hntoniscus, we
shall see that it presents nothing particularly remarkable.
Compared with the Bopyrus-type, our crustacean has only
undergone a considerable reduction of its various systems of
organs.
The tegumentary system, cuticle and dermis is very like that
of the other Isopods. It is clothed internally with a muscular
layer, which enables the animal to perform rather slow vermi-
form movements of contraction.
The nervous system appears to me to be reduced merely to
the cervical and anterior ventral ganglia; but my researches
in this direction are too incomplete to enable me to deny
absolutely the existence of the ventral chain. The movement
of the abdominal plates even leads me to suppose that this
chain does exist.
The digestive tube commences with a mouth constructed
for sucking, and placed at the lower part of two folds in the
form of a sucking-cup; the mass in the form of a brain, called
the head by Fritz Miiller, is hollowed internally by a cavity,
the walls of which are lined with folds and villosities like
those in the stomach of the Bopyrt. These villosities have
already been indicated by Rathke, Cornalia, and Panceri.
This is therefore a true gastric cavity ; and this apparatus, as
a whole, would be better called cephalogaster.
The digestive apparatus is then continued by a short
straight tube, terminated cecally, at the anterior part of
which the so-called hepatic ceca open.
I have sought in vain for a terminal interstine comparable
to that described by Buchholz in Hemioniscus ; I have been
M. A. Giard on the Genus Entoniscus. 149
unable to find any thing like it. Here, therefore, we have a
fresh confirmation of the general law, according to which the
more internal a parasite is, the more degraded is its digestive
tube. ‘This progressive degradation, which goes on increasing
from the genus Bopyrus to attain its maximum in the Znto-
nisct, passing through the genera Hemioniscus and Crypto-
niscus, reminds us precisely of what is observed in the
Diptera of the family Cistride, in which the degradation
becomes progressively more marked from the cuticolar
ie to the gastricolar types, passing through the cavicolar
orms.
The hepatic ceca (for which I retain this old name, but
without wishing to prejudge their true physiological part) are
certainly homologous with the organs of the same appearance
which we meet with in all Isopoda *.
These cxca form two large lateral sacs which occupy all
the thoracic portion and even a part of the abdomen of the
Entoniscus ; their internal cavity is very spacious, as may be
seen from the section drawn in fig. 7. The wall is covered
with slight glandular folds, enclosing a brown substance, the
aspect of which reminds one of what we have agreed to call
liver in invertebrate animals.
Kowalevsky was the first to indicate that the racemose
hepatic ceeca described by Rathket in Bopyrus (‘Icones zooto-
mice’ of V. Carus, Taf. xi. fig. 1, h) do not open directly into
the digestive tube, but that they all open imto a common
canal, which itself opens at a single point into the stomach,
as in the other Isopods. This observation is perfectly correct;
and I have been able to verify it in several species of Bopyrus
and Phryxus. All the difference between the hepatic gland
of the Bopyri and that of the Hntonisc?, therefore, consists in
that in the former this gland becomes ramified and acquires a
higher degree of differentiation. It may be said to be a dif-
ference analogous to that which exists between the simple
pulmonary sac of the Amphibia and the complicated lung of
Mammalia and Birds.
The circulatory system consists, in the first place, of a
median dorsal vessel, upon the course of which is placed the
heart, the beatings of which are very visible through the
transparent integument of the animal. ‘There are besides, on
* These organs likewise exist in the Cryptonisci, in which I have indi-
cated them, mistaking, however, their true relations. There cannot be
any connexion between the ovary and these enormous ceca which open
into the digestive tube.

the ventral side, lateral vessels which send forth branches
to the fringed plates of the abdomen.
These fringed lamine may be regarded as true branchie.
Moreover they occupy the position of the branchial laminz of
the normal Isopods. Their excessive development in the
Entonise? is easily explained in the following manner.
We have stated that the Hntoniscus in the body of its host
is completely surrounded by a fine membrane. This mem-
brane does not belong to the parasite; it is the continuation
of the membrane which clothes the viscera of the crab and
separates them from the branchial cavity. This membrane is
gradually drawn back by the growth of the Entoniscus, which
is thus enclosed in a sort of pouch formed by invagination.
From this it results that the EHntoniscus, as Fritz Miiller
justly points out, is an external parasite, although it appears
to be in relation with the most internal viscera of its host.
That the Bopyride need well aerated water constantly
renewed, appears clearly from the position which they take
up in the various animals to which we find them attached.
The typical Bopyrt lodge themselves in the branchial cavity
of the Macrura and Anomura, where they draw from their
host a revivified blood, and themselves find constant fresh
supplies of water. Therefore their respiratory apparatus is,
in general, but slightly developed. The Phryat attach them-
selves to the abdomen of Paguri at the spot where the ova
are collected in the females of those animals—that is to say,
at the point where the movements of the infested animal
also allow of a ready renewal of the water. Nevertheless,
as this renewal is less perfect than in the preceding case,
the abdominal lamine are already much better developed
than in the Lopyri properly so called.
In the Lntonisct the position of the animal, in a deep in-
vagination of the inner wall of the branchial cavity of the
crabs, renders respiration much more difficult. Hence the
respiratory lamella have attamed a much more considerable
development, and their undulated and crisped surface converts
them into regular sponges constantly impregnated with liquid.
Their movement of contraction, however, enables them to
drive off this liquid, and to draw in fresh supplies when the
necessity for so doing is felt.
In E. porcellane, in which the abdominal feet have re-
tained an ancestral form, it is the appendages of the thorax
that have been modified and converted into undulated
lamellee.
It is clear, moreover, that these various peculiarities are
serviceable not only to the adult Bopyride, but also to their
M. A. Giard on the Genus Entoniscus. 151
embryos, which, like the ova of all the other Crustacea, need,
for their development in the incubatory cavities, perfectly
aerated water. It is only necessary to place a female of Bopy-
vus, separated from her host, in a glass filled with sea-water,
even very pure and renewed several times a day, in order to
see that the development of the ova, contained under the ven-
tral lamella, is soon arrested.
We have given above the description of the ovary. It will
be sufficient to add that near the aperture of the ventral ovi-
gerous sac we find two colleteric glands, the secretory ducts
of which open not far from the apertures of the ovary near
the small ventral eminences (Pl. X. figs. 7 & 2). These
glands no doubt secrete the shell of the egg. There are
analogous glands in Hemioniscus.
Notwithstanding careful search, I have been unable to
meet with the male of either of the two species of Hntoniscus
that I have observed. I have vainly sought for it upon the
body of the female and upon the crab parasitized. The notion
that these Hntonisct may be hermaphrodites evidently presents
no absurdity & priort. In fact we are acquainted with her-
maphrodite types in certain zoological groups which are
composed principally of forms with separate sexes. Speaking
very generally, parasitism, or even fixation (which is only a
first degree of parasitism), pretty frequently induces the deve-
lopment of the two sexes in the same individual (Cirripedes*,
Ascidia, Acephala).
As long ago as 1866 Kowalevskyt observed the testes
and the mobile spermatozoids of a fine Peltogaster parasitic
on Callianassa subterranea, and since described by Kossmann
under the name of Parthenopea. He states, in the memoir,
that he has met with hermaphroditism in several other species
of Peltogaster and Saceulina.
Kossmann, in a memoir upon the Suctoria, has also figured
(in 1872) the spermatozoids of several species, but did not see
the mobile form of those elements. Kossmann’s memoir was
first published in a journal which is not much diffused (‘ Ver-
* The hermaphroditism of the parasitic Cirripedes of the group Suc-
toria or Rhizocephala was long in doubt in consequence of the numerous
errors which haye been published on this question. It is not very long
since Hesse described as the male of Peltogaster a Bopyride Isopod
crustacean! Such fancies would not deserve to be noticed here if they
had not acquired a certain importance, even in foreign countries, by the
support they have met with from certain Parisian savants. It is not
without astonishment that we find a man of the importance of Spence
Bate still asking in 1878, “ What do we know of the male of the Suc-
toria ?” (Ann. & Mag. Nat. Tist., June 1878).

handl. der phys.-med. Gesellsch. in Wirzburg,’ Bd. iii.
Heft 4, p. 296, pls. xvi.-xvii.). Without knowing of these
previous investigations, I occupied myself with the same ques-
tion in 1873; and I then gave, in the ‘Comptes Rendus’ of
the Academy of Sciences, the description of the testis and
perfectly mature spermatozoids in Sacculina carcint and in
two species of Peltogaster.
But in the present cases this hypothesis of hermaphrodi-
tism loses much of its probability, if we consider that Fritz
Miiller has described the male of all the species of Hntoniscus
that he has met with. ‘There is very little probability that,
in the same genus, species so nearly allied should present a
physiological and morphological dissimilarity of such impor-
tance; and I prefer to assume that my unskilfulness, or my
limited opportunities, have prevented me from meeting with
the males of L. Cavolinii and EL. Moniezi?. I need not say that
I have searched fruitlessly for a testicular gland, and that I
have observed nothing resembling the spermatozoids of the
Bopyride.
The youngest females of Hnioniscus Cavolinii that I have
been able to observe were in the same stage of development as
the young Entoniscus Moniezit, figured Pl. X. figs. 3 & 4. The
general form was identical; one saw the same rudiments of
thoracic limbs, the commencement of the formation of the
ventral ovigerous sac, and the two lateral ventral folds of the
future dorsal pouch. But there were as yet no traces of the
ovarian prolongations.
As a difference of specific value between 2. Cavolinii and
Ei, Moniezit at this period of evolution, I will indicate only
the much greater development of the first pair of abdominal
lamine in L. Moniezit. In Entoniscus Cavolinit the first
four pairs of lamine have then nearly the same development ;
and it is only afterwards that the first pair grows more than
the others.
III. EMBRYOGENY.
The anatomical details which we have just given present a
great number of gaps, which will be excused, I hope, by all
zoologists who have paid attention to the study of parasites.
The scarcity of materials and the obscurity of the subject are
two terrible obstacles, over which it is very difficult to
triumph.
What we have now to say as to the embryogeny of these
animals is still more incomplete; and, unfortunately, long years
will probably be necessary to arrive at satisfactory notions
upon this subject. Notwithstanding the innumerable quan-
tity of ova which the female Hnétoniscus contains, it may be
M. A. Giard on the Genus Entoniscus. 153
said that we find ourselves in a state of actual poverty, since
all these ova are at the same degree of development, and it is
impossible to make them continue their evolution outside of
the maternal organism.
I can say scarcely any thing about the embryo before its
escape from the egg. The segmentation appears to be holo-
blastic; the embryo is bent backward, like that of all the
Bopyrid. The first six pairs of thoracic feet appear at first
all similar; the seventh segment is destitute of appendages.
The five pairs of abdominal feet, which, in my opinion,
correspond to the natatory feet of the Cypris form of the
Cirripedes, or to the cirri of the adult Zepas, appear first, and
all together.
On each side of the embryo, at the stage represented by
fig. 9, we see a line of refringent bodies. I have seen similar
lines in the embryos of several genera of Bopyride. In Hn-
toniscus we see later on at the same place (fig. 9) two lines of
pigment-cells. The pigment of Hnioniscus has never offered
me the: characteristic odour of that of the Cryptonisc?, an
odour which is correctly indicated by Dr. P. Fraisse.
The embryo at the moment of its escape from the egg
(fig. 10) is about 0°3 millim. in length. It presents two
pairs of antenne: the inner ones, which are short, are termi-
nated by two tufts of sete; the outer ones, which are much
longer, are formed of six joints, of which the third bears two
sete, much longer than the others. The front is nearly
straight, as in the embryo of Hntoniscus porcellane. Besides
the lateral eyes, which are double and correspond to the
definitive eyes of the ordinary Isopods, it possesses a median
eye, presenting exactly the structure of the nauplian eye of
the Copepods &c. We find in it, in fact, two crystallines
(figs. L1, 12), two optic nerves, and a strong black pigment-
spot, the anvil-like form of which perfectly recalls that of the
eye of the nauplius of the Cirripedes or of the free Cope-
ods.
Fritz Miiller indicates in the middle of the front of the
embryo of 2. porcellane a transparent spot, which, no doubt,
is only the rudiment of a similar nauplian eye.
Dr. Fraisse has also observed something analogous in a
species of Cryptoniscus (C. monophthalmus, Fy.). ‘The male
of this species possesses a single median eye instead of the
lateral eyes of the other types of the same genus*.
* The Cypris-larva of an undetermined Cirripede, taken at Wimereux
in September in the muslin net, also presented three eyes—the median
eye of the nauplius and the two ordinary lateral eyes of the pupa-stage.
A median pigment-spot also exists, besides the lateral eyes, in a branchio-
pod crustacean, Holopedium gibberum, Zaddach.
5 ae M. A. Giard on the Genus Entoniscus.
The presence of a nauplius-eye very distinctly formed in
the embryo of £. Cavolinit appears to me to be of some im-
portance as a trace of the nauplius phase in the embryogeny
of the Isopods. Hitherto we had no factual argument to
appeal to in order to connect the Isopods with the original
form common to all the Crustacea. The opinion of Fritz
Miiller, who regards the embryonic membrane of Ligia or
Oniscus as representing the nauplian skin, seems to me desti-
tute of foundation. In all the groups in which embryonic
membranes exist, these membranes are superadded in certain
forms as protective organs of the typical embryo without
modifying its essential characters. ‘They are in general ex-
odermic folds performing the part ofan amnios. This is what
takes place, for example, in insects, where these membranes
may be formed in various fashions, and have no real morpho-
logical significance from the point of view of comparative
embryogeny. These membranes are most frequently deter-
mined by physiological reasons, and may disappear or be re-
tained in very nearly allied types.
The presence of the eye, so characteristic of the nauplius,
seems to me, on the contrary, a mark of great value for the
phylogeny of the Arthrostraca.
Each of the feet of the first five thoracic pairs terminates in
a prehensile hand (fig. 8), of which the penultimate joint is
oval, and bears two denticles on the side which is turned to-
wards the opposable claw.
The sixth pair of thoracic feet, so exceedingly characteristic
for the distinction of the species of the genus Hntoniscus, does
not at all resemble the same part in the types hitherto de-
scribed. It consists of five joints; that which corresponds to
the hand of the other pairs is more elongated (fig. 6, a), and
terminates, on its inner margin, in a small curved fixed tooth ;
its outer border is produced into a straight rod, as long as the
joint which supports it, and furnished at its extremity with a
tuft of rigid setee.
Here, then, we find a remarkable confirmation of the law
demonstrated by Darwin and Fritz Miiller:—When, in a group
of animals, an organ presents an exceptional development,
this organ is at the same time subject to great variability in
the various species of the group.
It is probable that this sixth pair of feet aid the embryo to
make its way into the interior of the crab in which it is to
undergo its retrograde metamorphosis. The variations which
it presents in the different species of Hntoniscus are conse-
quently in relation to the peculiar conformation of the branchial
cavity of the animal infested.
M. A. Giard on the Genus Entoniscus.
155
The five pairs of abdominal feet are all constructed in the
same fashion: the basal joint bears one or two sete; the
terminal setigerous joint presents a straight margin (fig. 10, a)
which bears two sete; a third is inserted at the acute ex-
tremity.
The only internal organs visible in the embryo are the
hepatic ceca and the heart, which latter is seen beating
actively in the dorsal part of the first segment of the ab-
domen.

I incline to think, however, that with these animals, as
with the other Bopyride, copulation takes place before the
commencement of parasitic lite.
In most [sopods the male is

smaller than the female ; and sometimes the difference of size
in the two sexes is very great. Several species of Jdotew
are remarkable in this respect. It has frequently happened
to me to capture these animals in the muslin net; and almost
always one meets with them in couples; the male, one third
or one fourth the size of the female, is placed between the feet
of the latter on the abdominal surface, absolutely in the same
position as the male of the Bopyride. This is the case also
with various Cymothoade ; and in some species of this group
it is necessary, as in the Bopyride, that copulation should
precede parasitism. This occurs notably in a curious Javan
species described by Herklots*.
In the course of this memoir I have several times alluded
to a second new species of Hntoniscus, which I have also met
with at the Pouliguen, and which I have named Z. Monieziz,
dedicating it to R. Moniez, preparator of zoology at the
Faculty of Sciences of Lille, who accompanied me in my
journeys on the shores of the Loire-Inférieure.
This species appears to be very rare, since I have seen
only two individuals of it—an adult female and another at a
less developed stage (figs. 38, 4), both found in the same
example of Portunus puber. This crab had been collected at
the island of Leven, opposite to the point of Peu-Chateau and
the open coast of Pouliguen. In order to find it again I have
in vain examined several hundreds of the Portunus fished on
the coast.
I have already indicated above some differences between
this species and that of Cavolini in the stage represented
(figs. 3, 4).
The adult individual unfortunately contained only slightly
developed embryos; and I was unable to compare these
embryos with those of the species from the G'rapsus. ‘The diffe-
rential characters were furnished to me by the colour of the
ovary and of the ovigerous sacs—peculiarities of which Fritz
Miiller ought to have made use to distinguish the various Hn-
tonisct parasitic on Porcellane. In EL. Moniezii the ovigerous
sac is of a nankeen-yellow, instead of presenting the greyish-
yellow colour of #. Cavolinii at the same grade of evolution
of the eggs. ‘The ovarian gland is yellow with a rosy tint ;
it is straw-yellow in the parasite of the Grapsus.

158 Prof. A. Newton on some Moot Points
XVIII.—On some Moot Points in Ornithological Nomencla-
ture. By ALFRED NEwron, M.A., F.R.S., &e.
Criticism by competent critics is the last thing of which an
author ought to complain; and I am far from objecting to the
spirit of the animadversions which Mr. Sclater and Mr. See-
bohm, in ‘ The Ibis’ for the present month, have made on
certain birds’ names used by me in the revised edition of
Yarrell’s ‘ British Birds.’ Indeed [ have to thank both those
gentlemen for the friendly, not to say flattering, terms in which
they are pleased to speak of my labours. It becomes me,
however, to attempt to prove that I have not gone so far
astray as they would lead their readers to suppose; and this,
I trust, I may succeed in doing to the satisfaction of impartial
judges.
Mr. Sclater begins his remarks (‘ Ibis,’ 1879, p. 346) by
reeretting that I have not explained my reasons for adopting
certain names in place of those usually current. To this my
reply is, that, where space allowed me, I have done so, but
that, in general, the amount of more important matter which
I have had to insert has utterly precluded me from entering
at any length on a subject like nomenclature, which interests
but few persons—those few being experts, who commonly
prefer investigating the subject for themselves.
My friend next touches the question of the type of the
genus Striv. But here he has nothing new to offer, and con-
tents himself with the opinions that had before been expressed
thereon by Mr. Salvin and Mr. Sharpe. Of those opinions I
need not say more now; for some years since I treated them
in considerable detail (‘ Ibis,’ 1876, pp. 94-105). To the
remarks I then made Mr. Sclater does not refer. If he has
forgotten them I freely forgive him the omission; if he has
not forgotten them, I well understand that it may be easier to
avoid than to answer the arguments therein adduced*.
We then come to the specific name of the Short-eared Owl,
for which I have used that published by Pallas in 1771f.
* For those who may not have the third series of ‘ The Ibis’ at hand,
it may be convenient to state here that the two principal positions I
maintained were :—
“(1) That the type, according to the modern notion, of the Linnxan
venus Strix, is clearly and indisputably S. stridula.
“ (2) That in subdividing a genus Brisson’s right to affix its original
name to the portion of it he chose is not affected by his exceptional posi-
tion as regards specific names, and that the type of his restricted genus
Strix is also S. stridula.”
+ Mr. Sclater says that herein ‘“ other authors have blindly followed”
me. Who they may be I do not stop to inquire; but surely it is an
assumption to infer that their eyes and opportunities of using them are
not so good as his own,
in Ornithological Nomenclature. 159
Mr. Sclater expressly guards himself against aflirming that
the “ Stryx accipitrina”’ of Pallas was not a Short-eared Owl ;
but he notices that its head is described as “¢naurdtum,” and
that “‘ no dimensions whatever are given.”’ The latter state-
ment “is not quite correct ;” for Pallas begins his description
with the words “ Magnitudo circiter St. Vlule ;’” and as to
the fact of his having overlooked the tufts with which the
head of this species is furnished, he is neither the first nor the
last ornithologist who has done the like—as witness Buffon
(Hist. nat. Ois. i. p. 372, pl. xxvii.), and, with regard to the
female, our own Bewick. Indeed, as every one must know
who has handled fresh examples, its tufts are not generally
seen till they are sought. Moreover Mr. Sclater asserts
“that it does not appear that the Strix accipitrina was really
ever obtained, but only ‘observed.’” How then, I would
ask, came Pallas to mention such a minute character as that
of its remiges “ extima sola serrata,” unless he had pretty
closely examined a specimen? But really to do away with
any reasonable doubt as to what his bird was, we have his
contemporary 8. G. Gmelin, in 1774, giving (Reise u. s. w.
i. p. 163, pl. ix.) an effective and unmistakable figure of
the species under that very name, and, speaking of various
Owls he had met with at Astrakan, particularizing “ wiederum
eine besondere Art, die nach emem Privat-Schreiben des
Herren Professors Pallas an mich in dem ersten Theil seiner
Reise-Beschreibung unter dem Nahmen Sérix accipitrina
beschrieben seyn soll, dass ich von derselben auf der 9ten
Platte nur eine deutliche Abbildung mittheile.” The evi-
dence thus afforded is irresistible, even if Pallas’s description
of the species, saving the omission of the tufts, were not quite
as diagnostic as many descriptions I have elsewhere read of
other Owls*.
The next point on which Mr. Sclater differs from me relates
to the generic name of the Tawny Owl; but on this, from what
I have above said as to the type of the genus Sirix, I need
not dwell, and so I pass to the question of the specific name
of the EHagle-Owl. The erroneous statement that Thomas
Forster “gave no such name” as Lubo tgnavus to this
species, and the ingenious hypothesis of that author’s having
published it “as a synonym which he did not adopt himself,”
might have been spared had my critic but looked further into
the subject. In the second catalogue, wherein Forster says
(p. 40) he has “ founded a nomenclature,” will be found (p. 46),
* Mr. Sclater also errs in asserting that Pallas “subsequently always
called the Short-eared Owl] Strix @golius.” In his ‘ Zoographia’ he in-
cludes the species twice—once under the former name, but the second
time (i. p, 322) under that of S. uula!
160 Prof. A. Newton on some Moot Points
in all the dignity of capitals, ““BvBo IGNAVVS,”’ as the author’s
deliberately adopted name for the Hagle-Owl, which no sugges-
tion of its being in the first case a synonym can explain away !
Perhaps Mr. Sclater may say that I ought to have added a
reference to this fact; but it certainly never entered my head
that the omission would mislead so well-read an ornithologist,
and, accordingly, I thought it enough solely to quote the first
use of the name, as is my custom*.
Lastly, as regards Mr. Sclater, I come to the case of Athene
versus Carine. He rightly assigns the reason why I adopted
the latter. Athena had a prior use in entomology, and no one
can doubt that Athena and Athene are one and the same word,
the difference of the final letter being merely dialectic. Now this
is not so with Pica and Picus, which he cites as a parallel
ease. ‘Those are perfectly distinct words, to which a perfectly
distinct meaning has been attached from the days of Pliny to
our own. Iam sure Mr. Sclater is too good a scholar not to
admit this fact on reconsideration; and that he objects to
homonyms is evident by his substitution, in this very number
of ‘The Ibis’ (p. 388), of Calochetes for Euchetes, because,
though more than twenty years ago he conferred the latter on a
Tanager, it had, more than twenty years before that, been ap-
plied to a Beetle.
The objections raised by Mr. Seebohm refer to another
eroup of birds, the Warblers ; and he has my fullest sympathy
in his difficult task of trying to define it and of determining
the names, generic and specific, which its different members
should bear. Had I leisure to do so, there are several points
in his article (‘ Ibis,’ 1879, pp. 308-317), of far greater im-
portance than nomenclatural quibbles, on which I would
comment; for I confess that in some places I fail to catch his
precise meaning; but here I shall limit myself to two, in
which he has arrived at results differing from those I have
reached,
The first of these concerns the specific name to be applied
to the Greater Whitethroat. To the best of my belief, no other
writer for the past sixty years and more has questioned the
fact, that the bird represented by D’Aubenton (Pl. Enl. 581.
fig. 1) was of this speciest. ‘Temminck, not once but twice,
* Mr. Sclater thinks that “the excellent name of Bulo maximus,’ be-
stowed by Fleming in 1828, should be adopted for this species. I have
accordingly to remind him that Boie, six years earlier, called it B. athe-
niensis (‘ Isis,’ 1822, p. 549), which looks as if Fleming’s “name must
therefore be rejected.”
+ There is an apparent but not real exception in Vieillot ; for his Sylvia
Fruticeti is admittedly the Greater Whitethroat in autumnal plumage (cf.
Degland, Orn. Eur. 1. p. 536),
in Ornithological Nomenclature. 161
and that in both editions of his ‘Manuel’ (1815, pp. 118,
125; 1820, 1. pp. 208, 226), spoke most positively on this
point. Kuhl, Bonaparte, Gray, Gerbe, and others have cited
the figure without hesitation, some of them more than once.
Years ago I showed the plate to several of my ornithological
friends, who were well acquainted with birds and also with
the representations of them by draughtsmen of the period.
No one of them but, after due examination, declared himself
satisfied that the subject of the figure was a Greater White-
throat taken in autumn. Indeed it cannot have been any-
thing else; the rufous vertex, nape, and mantie, the rufous
edging of the wing-feathers, coverts as well as quills, the
white outer web of the external remiges are characters which
admit of no mistake. And yet Mr. Seebohm not only asserts
that “it is impossible to accept this figure asa clear definition
of a Whitethroat,” and “ equally impossible to determine what
bird stood as model for” it, but he suggests the serious
charge that D’Aubenton “ ‘ evolved’ the figure ‘ out of the
depths of his moral consciousness,’ and coloured it to agree
with Buffon’s description.” This accusation seems to me
groundless ; and, for the credit of ornithology, I wish it were
withdrawn. For more than a century D’Aubenton’s draughts-
man Martinet has enjoyed unblemished fame as a faithful
portrayer who, if wanting in the artistic execution we have
occasionally seen since, yet had skill to seize and reproduce
the most characteristic features of any bird he figured, as he
most certainly did those of the Greater Whitethroat in the
plate which Mr. Seebohm, without adducing the slightest
evidence, accuses him of drawing from imagination,
It remains to be said that the name Motacilla rufa be-
stowed by Boddaert applies solely to the subject of this figure,
and not to any Fauvette or Grisette described by Brisson or
Buffon. Mr. Seebohm’s argument that Boddaert’s name
should be rejected on other grounds involves, I think, some
confusion of ideas, upon which I need not dwell. Its admis-
sion would be incongruous with the rule of priority.
This same confusion of ideas seems to me to underlie some
of Mr. Seebohm’s remarks on the second point at issue, my
having restored its Linnzean name to the Garden- Warbler ; for
the mistakes of subsequent authors form no valid objection to
retaining it in its original sense. ‘The state of the case is
this. The Motacilla salicaria of the ‘Systema Nature’ rests
actually on the bird described by that name in the ‘ Fauna
Suecica:’ synonyms have nothing to do with it; and here, as
elsewhere in like cases, their consideration must be excluded.
Turning to the work last mentioned (ed. 1761) we find the
162 On some Points in Ornithological Nomenclature.
brief diagnosis quite compatible with that of the Garden-War-
bler, and the description, which is much fuller than that given
in the ‘Systema,’ incompatible in one character only—“‘ linea
albida supra oculos,” while in other respects it fits the Garden-
Warbler alone of all Swedish birds with which Linneus was
likely to have met. Mr. Seebohm considers that the phrase
“superciliis albis’’ condemns the description; but I assure
him he is in error, for superciliwm does not necessarily mean
an eyebrow, or still less a “ superciliary stripe ;” and the word
is doubtless here used for the eyelids, which in the Garden-
Warbler are clothed with white feathers. Again, the words
** Pedes fulvi’”’ form no part of the original description, while
his suggestion that Linneeus’s bird was an Acrocephalus is
utterly at variance with the statements ‘‘ Rectrices remigibus
concolores,” and “ Habitat in sylvis,’”’ as well as with the
closing remark of the description, ‘‘ Avis valde affinis Sylvie
[¢. e. the Greater Whitethroat], modo non sexu tantum dis-
tincta.”’ Nilsson, unquestionably the best authority on the
birds of Sweden, has never faltered in deeming the M. sali-
carta to be the Garden-Warbler*; and I cannot at all
agree with my critic that, under all these circumstances,
Linneus “failed to define the species clearly,” or that his
description of it is invalidated by the single inaccuracy above
noticed. As well might we declare that his Malco haliactus
is not the Osprey because he said of it, ‘ Pes sinister semi-
palmatus” +!
I have thus tried, as briefly as I could, to answer the objec-
tions urged by my good friends, and, I trust, with some success,
though I have not the vanity to suppose that I shall affect their
opinions, for all must allow that a discussion on nomenclature
is generally profitless. I cannot even say that I desire to make
converts of them, since the names used by zoologists are almost
a matter of indifference tome. I am simply striving to carry
* Herein Gloger (Handb. p. 243) and, it would seem, Lichtenstein
concur,
+ I said before that I had no wish to criticise such parts of Mr. See-
bohm’s paper as do not refer to myself; but I must remark that his
comments on the M. borin of Boddaert seem to be beside the question.
In almost every department of zoology we have long had local names
brought into scientific nomenclature, witness Lemur mongoz, Lanius
tschagra, Coluber hadje, Rana pipa, and Salmo hucho, among a multitude
of others. The practice is not graceful; but Motacilla borin is hardly
worse than any of the above, and quite as good as Lstrelda astrild,
Fypsipetes ourovang, or Penelope marail, which are in common use. I
cannot help thinking that those writers who may hereafter forego the
expressions Sylvia cinerea and S. hortensis will not do so in favour of
S. communis and S, simplex, in spite of my friend’s recommendation.

forth by the British Association, and this without regard to
consequences. I only regret that the attempt involves so much
toil and waste of time; but I will not prolong these tedious
remarks on so trifling a subject; I will only say, I have no
wish to be thought an infaihble interpreter of those rules, and
that I am no believer in nomenclatural finality ; for I bear in
mind that the truthful lines are here applicable :—

And fix their own, with labour, in the place.
Their own, like others’, soon their place resigned,

XIX.—Deseription of two new Species of Plectopylis, a Sub-
genus of the Helicide. By Lieut.-Colonel H. H. Gopwin-
AvuSsTEN, F.Z.S. Ke.
AMONG some specimens of Plectopylis pinacis, Benson, of large
size from Darjiling, given me by Ferd. Stoliczka, are several
smaller shells which no doubt are referable to P. macromphalus,
W. BIE, var. minor, alluded to in the ‘ Journal of the Asiatic
Society of Bengal,’ 1870, p. 18. Mr. Blanford shows that it
is quite distinct from pinacis, and, perhaps not having mature
specimens of this Darjiling shell, considered it the same as the
Khasi shell, to which it has a very great resemblance. I
have now before me a very large number of this small form
also from Darjiling, given me to look through by Mr. G.
Nevill; and_on a closer examination the differences are well
marked.
In a drawing made under the superintendence of Stoliczka
the animal of this small form of Plectopylis is represented as
of a pink colour.
In form the shell resembles macromphalus; but it may
be distinguished by possessing a hairy epidermis, which,
on microscopical examination, differs from pénacis in being
laterally barred with brown, whereas macromphalus, in a large
series, is uniformly coloured—also by the more distinct charac-
ter of a ridge on the parietal side of the aperture, not present
in the Khasi shell at its most advanced stage of growth. In
most respects it is really a closer ally of pinacis from the
same locality.
The second species is also supposed to have come from the
same part of the Himalayas.

Locality. Dayjiling hills.
Shell sinistral, openly umbilicated, discoidal, hirsute. Sculp-

fine and regular ribbing; colour pale umber, with regularly
disposed broadish transverse bars of sienna-brown ; spire flat,
only the first three whorls slightly rising above the others ;
suture shallow. Whorls five, subangular on the periphery
of the last, which has four distinct rows of short hairs, entire

stome lunate, slightly flattened on the upper outer margin,
but very little reflected, the inner margins connected with a
distinct ridge on the parietal side.
The parietal vertical lamina is simple, with no distinct hori-
zontal plica below it, as in macromphalus ; the palatal plice
are six in front, four behind, the basal one in front thin and
longer than the others.
Plectopylis Hanleyt, n. sp.
Sikkim ? No history ; only one specimen, in the collection of
Mr. Sylvanus Hanley.
Shell sinistral, depressedly conoid, openly umbilicated, pro-
bably hirsute when young. Sculpture coarse, irregular, trans-
verse ridges. Colour uniform ochraceous. Spire conoidal ; apex
blunt, smooth. Suture well marked. Whorls six, close-
wound, convex. Aperture semicircular, diagonal; peristome
somewhat thickened, white, with a thin callus on the parietal
margin, not to the extent of a ridge.
Size—major diam. 5:5, minor diam. 5:0, alt. 3:0 millims.
Parietal vertical lamina simple; palatal plice in two rows,
four long in front, four short behind, and one basal long.
This shell is very distinct ; it has somewhat the form of P.
plectostoma, but is not so angular on the periphery, while the
internal plication is quite different, besides being so very much
smaller in size.
XX.—On the Occurrence of Neomenia (Solenopus) dn the
British Seas. By the Rev. A. M. Norman.
THE translation of Koren and Danielssen’s paper on. Soleno-
pus, in the ‘ Annals’ for May, relates to a very remarkable
new order of Mollusca. “It will be of interest to your readers
to learn that the type species has long been known to me as
an inhabitant of the British Seas; and though at this moment

I cannot recall to mind with certainty other localities, I have
undoubtedly met with itin the Shetland seas. Last year I also
dredged it in the neighbourhood of Bergen, Norway, whence
also Koren’s and Danielssen’s specimens came. ‘he genus
and species must in justice bear the name bestowed upon .
it by Tullberg, who published an accurate description, illus-
trated by two plates of figures of the animal and its anatomy,
in 1875, at a time when M. Sars had only given the MS.
name. The synonymy of the British species will be :—

It will be seen from Koren and Danielssen’s paper that they
regard this curious animal as a mollusk, though so much
differing from previously known mollusks that it could not
be included in any of the established orders. It may be in-
teresting if I add here for comparison Tullberg’s concluding
remarks, after he has previously gone carefully into the
anatomy ; he says :—
“ As regards the systematic position of this curious animal,
some few remarks offer themselves ; but it seems safer to defer
all detailed discussion on this subject until more complete

investigation shall have been made. As elsewhere, embryo-
logy will give the best clue to its affinities. At present the
type of Mollusca and that of Vermes seem both to claim Neo-
menia as a distant relation, the latter perhaps with more
right than the former. Neomenia, however, presents consi-
~ derable deviations from both, in the absence of a radula, in
the structure of the alimentary canal and of the nervous sys-
tem, as also in other respects, as the form of the body and the
spines of the skin.”
PROCEEDINGS OF LEARNED SOCIETIES.
GEOLOGICAL SOCIETY.
March 12, 1879.—Henry Clifton Sorby, Esq., F.R.S.,
President, in the Chair.
The following communications were read :—
1. “On Conodonts from the Chazy and Cincinnati groups of the
Cambro-Silurian, and from the Hamilton and Genesee-Shale divi-
sions of the Devonian, in Canada and the United States.” By
G. Jennings Hinde, Esq., F.G.S.
After a sketch of the bibliography of the subject, the author
described the occurrence of Conodonts. In the Chazy beds they are as-
sociated with numerous Leperditie, some Trilobites, and Gasteropods ;
in the Cincinnati group with various fossils ; and in the Devonian
strata principally with fish-remains; but there is no clue to their
nature from these associated fossils. They possess the same micro-
scopic lamellar structure as the Russian Conodonts described by
Pander. The various affinities exhibited by the fossil Conodonts
were discussed ; and the author is of opinion that though they most
resemble the teeth of Myxinoid fishes, their true zoological relation-
ship is very uncertain. The paper concluded with a classification of
the Conodonts from the above deposits.
2. “On Annelid Jaws from the Cambro-Silurian, Silurian, and
Devonian Formations in Canada, and from the Lower Carboniferous
in Scotland.” By G. Jennings Hinde, Esq., F.G.S.
After referring to the very few recorded instances of the discovery
of any portions of the organism of errant Annelids as distinct from
their trails and impressions in the rocks, the author noticed the
characters of the strata, principally shallow-water deposits, in which
the Annelid jaws described by him are imbedded. A description
was given of the principal varieties of form and of the structure of
the jaws. They were classified from their resemblances to existing
forms under seven genera, five of which are included in the family
Kunicea, one in the family Lycoridea, and one among the Glycerea.
The author enumerated fifty-five different: forms, the greater pro-
portion of which are from the Cincinnati group.

pre-sacral, and one post-sacral vertebra. He established the Dino-
saurian nature of the animal represented by them, and offered proof
of its distinctness from already-known forms. He proposes for it
the name Vectisaurus valdensis, a name descriptive of the locality
and formation in which the remains were found by him. ‘The
charaeters presented by the genus Vectisawrus were stated to be as
follows :—Ilium with a long compressed antacetabular process,
having its greatest transverse extent in a vertical plane, and
strengthened by a strong ridge produced from the sacral crest.
Vertebre in anterior dorsal region having opisthoccelous centres,
their lateral surfaces longitudinally concave, transversely gently
convex, meeting below in a blunt keel.
2. “On the Occurrence of the Genus Dithyrocaris in the Lower
Carboniferous, or Calciferous Sandstone, Series of Scotland ; and on
that of a second Species of Anthrapalemon in these Beds.” By R.
Etheridge, Esq., Jun., F.G.S.
The author, in the first place, referred to the extension of the
range in time of the genus Dithyrocaris, by the discovery of nume-
rous fragmentary remains of D. testudineus, Scouler, in the Calcife-
rous Sandstone or Lower Carboniferous Series of the south of
Scotland, about the horizon of the Wardie Shales near Edinburgh,
and in the Cement-stone group of Roxburghshire.
A further and more complete description of Anthrapalemon
Woodwardi, Eth., jun., was then given, in which the characters of
some of the appendages were more particularly alluded to, such as
the eyes, inner and outer antenne, and first pair of ciliate appen-
dages, thus placing the stability of the species beyond a doubt.
The paper concluded with the description of a second species of
Anthrapalemon, from the Lower Carboniferous rocks of Roxburgh-
shire, for which the author proposed the name of A. Macconochit,
after the discoverer of the specimen. ‘This remarkable species, of
which the carapace is at present the only portion known, differs
essentially in the characters of this part of the body from all the
other described species of the genus.

Notice of a new Jurassic Mammal. By Prof. O, C. Marsn.
During a recent visit to the Rocky Mountains the writer spent
some time in examining the deposits known as the Atlantosaurus-
168 Miscellaneous.
beds, and was rewarded by the discovery of several interesting fos-
sils, among them the lower jaw of a small mammal. ‘This speci-
men indicates a diminutive marsupial, quite distinct from the one
previously described by the writer from the same horizon (Dryolestes
priscus)*, Which has hitherto been the only mammal known from
the Jurassic of this country.
The present specimen, which is from the left side, has the larger
part of the ramus preserved, with a number of perfect teeth in
position. Most of the symphysial portion is lost, and the posterior
part is missing or only faintly indicated. The jaw was remarkably
long and slender. The horizontal portion is of nearly equal depth
throughout, and the lower margin nearly straight. The form of
the coronoid process, condyle, and angle of the jaw cannot be deter-
mined from this specimen.
The remarkable feature in this jaw is the series of premolar and
molar teeth. These were very numerous, apparently as many as
twelve in all, and possibly more. The premolars had their crowns
more or less compressed and recurved ; and some of them were sup-
ported by two fangs. These had a small posterior tubercle at the
base of the crown, but none in front. The molar teeth were all
single-fanged, with elevated conical crowns; those preserved have
a distinct cingulum. The molars increase in size from the first to
the fifth. All the teeth preserved have the crowns raised consider-
ably above the upper margin of the jaw, and thus appear to be
loosely inserted. A large pointed tooth lying near the jaw appears
to be a canine.
The principal dimensions of this specimen are as follows :—
millim.
Length of portion of jaw preserved .....,.... 11:5
Dixtent of fivyeamolar teeth». 5). 2-003 <2 4-0
Extent of entire molar series ........5..+.. 50
Height of fifth true molar above jaw ........ 2:0
Depth of jaw below fifth molar ............ 1:75
Depth of jaw below last premolar .......... 15
Depth of jaw below first premolar .......... 1-4
In comparing this interesting fossil with the forms already
known, it is at once evident that it differs widely from any living
type. Its nearest affinities are clearly with the genus Stylodon of
Owen, from the Purbeck beds of England; and in many respects
the correspondence is close.
This specimen clearly indicates a new genus, which may be called
Stylacodon, and the species represented Stylacodon gracilis. With
the genus Stylodon, this form evidently constitutes a distinct family,
which may appropriately be termed the Stylodontide. The present
specimen indicates an animal somewhat smaller than a weasel, and
probably insectivorous in habit.—Amer. Journ. Sci. & Arts, July
1879.

Alleged Evidence of the Moa from feathered Ornaments of Maori
Weapons.
To the Editors of the Annals and Magazine of Natural History.
GuntLEMEN,—I have been favoured by a letter from Dr. Hector,
F.RS., dated “ Wellington, New Zealand, 20th May, 1879,” in-
forming me that the paragraph from the ‘Otago Daily Times’
quoted in my ‘ Memoirs on the Extinct Wingless Birds of New Zea-
land,’ vol. i. p. 448, relating to Dr. Hector’s examination of weapons
alleged to have been brought by Capt. Cook from New Zealand, is
incorrect, and that the editor’s remark, “ strange that this evidence
should have reposed in the cellars of the British Museum for a cen-
tury,” is quite unfounded, and that Dr. Hector “never made any
statement that could possibly bear such construction as is implied by
the writer of the paragraph in question.”—R. Owen.
On the Metamorphoses of the Blister-beetle (Lytta vesicatoria).
By M. J. Licurenste1n.
During the first warm days at the end of May or the beginning
of June, Blister-beetles in copulation are common on ashes, privets,
lilacs, &c., and when placed under a bell glass the females soon
make an excavation in the earth and deposit in it a mass of some
hundreds of rather elongated whitish and transparent eggs. In a
fortnight these eggs hatch and furnish the larve long since known
as Triungulint, and figured by Ratzeburg and others. They are
scaly, dark brown, with the meso- and metathorax and first abdo-
minal segment white. This larva has very acute jaws, black pro-
minent eyes, and two long caudal sete.
After several fruitless trials the author got them to feed at first
upon the stomachs of honey-bees, and then upon eggs and young
larvee of various species of bees, especially Osmiew and Ceratina
chaleites. Care must be taken to add honey to the eggs or young
larvee, because animal food is only fitted for this first larval form,
and the little Triungwinus seems to have an instinctive knowledge
that it must not touch the egg or larva unless there is beside it suf-
ficient honey to feed the form which is to succeed it. But when
this condition is fulfilled the little animal at once attacks the egg or
the larva, and is seen to increase in size rapidly.
On the fifth or sixth day it changes its skin. It loses its caudal
set and its brown colour, and becomes a small hexapod worm ; its
jaws become obtuse, its eyes much less brilliant; it quits the ani-
mal food and begins upon the honey. Five days later there is a
fresh change of skin, and the first modifications become still more
strongly marked ; the jaws become still broader, and the eyes more
and more obliterated.
Five days later there is another moult, when the eyes entirely
disappear, the feet and the jaws become brown and horny at the
extremity, the insect acquires the aspect of a small larva of a
Lamellicorn, and is evidently destined to burrow in the ground.
170 Miscellaneous.
Up to this point the author reared the larve in small glass tubes
like thimbles, corked and turned bottom upwards; and it was upon
the surface of the cork that the above changes took place. He now
employed a glass tube about 4 inches long and 1 inch in diameter,
stopped at the bottom with a piece of sponge, and filled with earth,
upon which he placed the Scarabeoid larva (as Riley has called the
same stage in Hpicauta). The larva immediately buried itself and
formed, a little above the sponge, against the wall of the tube, a
small chamber or cavity. In five days more a fresh change of skin
took place, producing a pupa like that of a Muscide, having four
small mamille at the apex, and three pairs of small mamille at
the part where the legs were. Its colour is horny white; and it is
motionless, looking exactly like a chrysalis, This state lasts
through the winter, the only sign of life being the issuing from its
pores, from time to time, of a transparent colourless liquid, which
remains for some days at the surface of the body.
On the 15th April this pupa burst its envelope, and gave issue to
a white grub, very like the Scarabeoid larva, but without its robust
claws and jaws, only presenting rudimentary feet, each composed of
three short and thick pieces. This grub moves slowly in its cell,
but does not go out of it or eat. On the 30th April there is a
fresh change, producing a nympha of the regular coleopterous type,
having all the limbs recognizable. It is at first white, but soon
becomes coloured; on the 17th May it was already very dark; and
on the 19th the beetle was visible in the cell ready to make its ap-
pearance. The complete development of the insect thus occupies a
year. The author believes that in nature the insect preys upon
burrowing bees, such as Halictus and Andrena.— Comptes Rendus,
May 26, 1879, p. 1089.
On the Systematic Position of the Volvocineee, and on the Limits of the
Vegetable and Animal Kingdoms. By M. KE, Mavrpas.
Since the publication of the memoirs of F. Cohn upon the Volvo-
cine, it seemed that the old debates respecting the systematic posi-
tion of those Microphytes were closed for ever. Every one, in fact,
had adopted the opinions of this naturalist ; and in all the general
treatises the Volvocinese are arranged with the Algxw. Stein, in his
fine volumes recently published upon the Flagellate Infusoria, recurs
to the old view of Ehrenberg, and reclaims the Volvocinex for the
animal kingdom, placing them among the Infusoria. As this ques-
tion affects important problems of cellular morphology and goes to
the very heart of the controversy on the limits of the two organic
kingdoms, I have thought it useful to make known to the Academy
some observations and considerations opposed to the conclusions of
the learned professor of Prague.
With Stein, the true criterion which enables a Protozoon to be
distinguished from a Protophyte is the simultaneous presence of
vibratile cilia or flagella, of contractile vacuoles, and of a nucleus
in one and the same creature. The Protozoa alone, according to
him, combine these three organs; no well-characterized plant pos-

sesses them together. He insists repeatedly upon this character,
especially at pp. 37, 47, and 51 of the work above cited. It is on
account of the simultaneous existence of these three organs, ascer-
tained by all observers, and particularly by F. Cohn, in the Volvo-
cinew, that Stein has excluded them from the vegetable kingdom,
and placed them among the Flagellate Infusoria. We shall find
that this character is of no importance, and that it occurs in Algw,
upon the vegetable nature of which Stein himself would not venture
to cast a doubt.
In the first place, it is useless to dwell upon vibratile cilia; every
one knows that all zoospores are furnished with them.
I pass to the contractile vacuole. And here I cannot refrain from
expressing my astonishment to sce a naturalist so exact, and gene-
rally so well informed, as Stein still denying the existence of this
organ (p. 47) in well-characterized plants. It has been seen by
Leitgeb, De Bary, Fresenius, Strasburger, Dodel-Port, and Cien-
kowski in the zoospores of Saprolegniew, of Cystopus, of Myxomy-
cetes, of Palmellaceze, of Ulothriv, of Hydrurus, of Chetophora, &e. ;
I have myself indicated it in Microspora floccosa and Stigeoclonium
tenue ; and I am convinced that it will be found in many other zoo-
spores if it is sought with high magnifying-powers and under good
conditions of observation. At any rate, the numerous facts already
ascertained are sufficient to refute the assertion of the celebrated
professor of Prague.
There remains the nucleus ; and Stein, in denying its existence in
the zoospores of the Algee, is in accord with everybody. All the ob-
servers who, since Thuret, have studied these organisms have been un-
able to discover a nucleus in them ; and Strasburger, quite recently
(‘ Botan. Zeitung,’ April 25, p. 274), assumes that the nucleus of the
zoospores of Ulothriv does not exist during its wandering period, and
is reconstructed afresh at the moment of germination. I have tried
to verify these assertions by the aid of very precise methods of ob-
servation, which I have long employed in the investigation of the
nucleus and nucleolus of the Infusoria ; and in the zoospores of
Microspora floccosa and of an undetermined @dogonium I have found
a very distinctly characterized nucleus.
I placed upon -the glass plate a small drop full of zoospores of
Microspora, covered it with the thin glass, and drew away the water
by aspiration, so that the zoospores were slightly compressed and
rendered nearly motionless. I then cemented two of the opposite
edges of the covering-glass with paraffin; and when it was well
fixed I caused a drop of alcohol to penetrate beneath it by drawing
off the water with bibulous paper. The zoospores were quickly
killed, and retained by compression between the two plates of glass.
I then replaced the alcohol with water, and the latter with saturated
picrocarminate. In a few minutes, the action of the reagent being
sufficient, I drew it off and replaced it by water, always by means
of bibulous paper, and then replaced the latter by crystallizable
acetic acid. This last reagent immediately clears the object; and
there is then seen, in the rostral region of the zoospores, a small
iy (7 Miscellaneous.
spherical nucleus of an intense red colour and very distinctly
defined, the rest of the body remaining very pale. As the acetic
acid is very volatile, one has only to place at the edge of the covering-
glass a drop of glycerine, which penetrates and replaces the evapo-
rated acid, preserving the form of the zoospores. We thus obtain a
preparation which only requires luting to be rendered permanent.
With the zoospores of Gdogoniuwm, of which I had only a small
number, I followed a rather different method. I killed them by
exposing the drop of water for a minute to the vapours of osmic
acid of 1 per cent.; I then cemented them under the covering-glass
by means of paraffin, coloured them with the picrocarminate, and
afterwards cleared them with the acetic acid and glycerine. The
action of the picrocarminate requires to be continued longer than in
the method with alcohol. The nucleus, situated in the middle of
the body, rather a little behind than in front, appears like a small
red sphere.
These zoospores were killed during their period of mobility. The
nuclei could not be confounded with the amylaceous corpuscles
which are met with in many Volvocinez besides the true nucleus.
The amylaceous corpuscles never acquire a red colour in prepara-
tions made in accordance with the methods here employed. We
have therefore to do with true nuclei, combined with vibratile cilia
and with contractile vacuoles, in zoospores of Alge. The two Algve
studied have zoospores belonging to two different types, those of
Microspora being flagellate, and those of @dogoniwm furnished with
a circlet of vibratile cilia. I am persuaded that if the zoospores of
the other Algz are suitably investigated a nucleus will be found in
in all of them.
The new criterion proposed by Stein for distinguishing the two
organic kingdoms is therefore of no value. Moreover, to seek a
well-defined boundary between plants and animals seems to me to
be a search very little in harmony with all the recent progress of
biological studies. The latest works all tend more and more to de-
monstrate that all the barriers which it had been attempted to raise
between these two groups have nothing fundamental or real in
them. From the physiological point of view, Claude Bernard has
established incontestably the biological unity of the living world.
The same conclusion springs from all the morphological results that
we have attained. At present neither physiology nor morphology
furnish any exclusive character belonging to one or the other of the
two kingdoms. When we study the amphibiological creatures which
swarm in the lower grades of the living world we may therefore
sometimes be puzzled where to class them. It is necessary then to
consider the totality of the characters ; and, without having recourse
to a third kingdom, we may almost always succeed in finding in
them tendencies and affinities which enable us to assign them a place
in the existing categories. It is by the consideration of these
general characters that I am in complete accord with Cohn and other
writers in classing the Volvocines among the Algze, side by side with
the Palmellacese, the Conjugate, and the Zoosporexe.—Comptes

No. 21. SEPTEMBER 1879.
XXI.—Remarks on the Recent Eryontide.
By the Rev. A. M. Norman, M.A.
I am sorry that Mr. Spence Bate’s reply to my inquiries
respecting the Crustacea described by him in a paper “ On
the Willemoesia group of Crustacea,” which appeared in the
‘Annals’ of December last, has remained so long unnoticed
by me. Unfortunately I have been so occupied by duties that
I have had no time for writing since the commencement of
the year.
Mr. Spence Bate’s paper just referred to was on a subject
of the greatest interest. In it were described a number of
Crustacea discovered by the ‘ Challenger’ in the abyss of the
ocean, extremely closely related to a group of animals which,
until recently, were believed to have been extinct for countless
ages; for they had only been met with in old fossiliferous
strata. The recent forms which have now been found are so
closely the counterparts of their ancient brethren, that they
mimic even minute details of sculpture in the several segments
of the body. Yet, at the same time, I found conclusions drawn
that were totally at variance with those at which I had arrived
from the examination of two specimens of these animals which
were dredged off the coast of Spain by the ‘ Porcupine’ expe-
dition of 1870.
Mr. Bate’s conclusions were to me startling ; but I did not
venture to say that they were wrong, since, with the mass of

material at his command, he had advantages in arriving at a
definite opinion which I had not myself enjoyed. The matter,
however, was of too great interest to pass by—of so much
interest, not to myself only, but to many others, that it seemed
the best way to ask Mr. Bate to give us further information
upon the points in question.
I am well aware that the style of my writing was terse. I
adopted the form of abrupt questions for brevity’s sake ; for I
was compelled to compress my observations into the small
space of three pages, which had been kindly accorded tome by
the Editors of the ‘Annals’ at a late period, when the matter
for the issue of the next month’s number had already been
determined on. I regret that it would seem that this brevity
savoured to Mr. Spence Bate of discourtesy.
Whether he is in the right or I am right in the views which
we respectively hold is a matter of no moment to myself, if
only the discussion of the points in question tends to throw
more light upon the subject.
My first and most important question was, “Are his genera
Pentacheles and Willemoesia any thing more than the other
sex of Polycheles?”” The first words of the reply are, ‘‘ Having
just given a paper to prove that they are distinct and not one
and the same species, I beg to repeat that Pentacheles and
Willemoesia are not the other sex of Polycheles, and to refer to
my paper for details.” I have referred again to his paper,
only to find, as before, that there was not one single allusion
to sex throughout it. It was this very omission which, on
first reading his paper, had led me to the suspicion that Mr.
Bate had fallen into the error of regarding certain modifica-
tions of structure as of generic value, which really were
dependent on and characteristic of the sex of individuals of
the same species. The information, however, upon the ques-
tion of sex which was wanting in the first paper has, in the
second, been supplied. I will now state the grounds on which
my own views were arrived at previously to the publication
of Mr. Spence Bate’s paper.
1. The known examples with the last pereiopods simple
(Polycheles, Bate) were males, while those which had the last

Endothiodon uniseries, Owen.” By Prof. R. Owen, C.B., F.R.S.,
F.G.8., &c.
The author referred to the characters assigned by him to his
Endothidon bathystoma, which had the alveolar borders of both
jaws toothless, perhaps covered with horn during life, as in the
Chelonians; whilst within this border there were three series of

teeth both in the palate and the mandible. He next described a new
species, under the name of Hndothiodon wniseries, founded upon the
fore half of a skull, having only a single row of teeth in the palate,
a character which may prove to be of generic importance. The
author finally discussed the relationships of this genus, which he re-
regarded as belonging to the order Anomodontia, and as showing,
like Oudenodon, traces of derivation from Dicynodon in the presence
of caniniform processes in the upper jaw. ‘The development of
teeth interior to the alveolar margins in both jaws was to be re-
garded as a character of family value; and the author remarked
upon the interest of the continuance of a common Ichthyic and
Batrachial dental character in exceptional cases among the Reptilia
up to the establishment of the Crocodilian type, above which, in the
vertebrate series, calcified palatal teeth no longer appear.
2. “Note (3rd) on Hucamerotus, Hulke, Ornithopsis, Seeley, =
Bothriospondylus magnus, Owen, =Chondrosteosaurus magnus,

In this paper the author gave a description of an unusually
perfect dorsal vertebral centrum of Ornithopsis, and some additional
information respecting the cervical and anterior dorsal vertebra.
He further compared the presacral vertebrae with those of several
recently discovered Dinosaurians of the Colorado region, showing
several agreements, but also such differences as to prove the
generic distinctness of Ornithopsis. He discussed the question of
the nomenclature of the species indicated in the title of his paper,
and maintained that the name Ornithopsis ought to be adopted for
the single genus to which he referred them.
3. “ Description of the Species of the Ostracodous Genus Bairdia,
M‘Coy, from the Carboniferous Strata of Great Britain.” By Prof.
T. Rupert Jones, F.R.S., F.G.S., and James W. Kirkby, Esq.
The long persistence of the genus Bairdia, from the Silurian
period to the present day, and its essentially marine character,
were first noticed ; also the relatively rare occurrence of any species
of Leperditia, Beyrichia, and Kirkbya (associates of Bairdia in
Carboniferous strata) in freshwater or estuarine beds. Carbonia, on
the other hand, was confined to the fresh or brackish waters in
which the Coal-measures were formed. The difficulty of defining
the species of Bairdia from carapace-valves alone, without limbs
and soft parts, and the possibility of several genera being grouped
under this head, were mentioned. The speciesof Bairdia described
and figured in this paper were, it is believed, all that have been
found in the British Carboniferous rocks, with the exception of
M‘Coy’s B. gracilis. Two of Count Miinster’s Bavarian Bairdie,
from Hof, have not yet occurred with us; neither have four of
Dr. D’Eichwald’s Russian Carboniferous species, nor the Australian

B. affinis, Morris. Including these, there are twenty-three known
Carboniferous species of Bairdia. Seven of these are recurrent in
the overlying Permian limestones, which have yielded twelve
species of this genus. With six Silurian forms, there are altogether
thirty-four recorded paleozoic species of Buirdia.
4. “ Report on a Collection of Fossils from the Bowen River Coal-
field and the Limestone of the Fanning River, North Queensland.”
By R. Etheridge, Esq., jun., F.G.S.
The collection on which the present paper was founded had been
received from Mr. R. L. Jack, F.G.S. ; and the information furnished
by it was supplementary to that obtained from Daintree’s collection.
The fossils are from three distinct horizons. The author first briefly
described the geology of the formations from which the fossils were
derived, and stated that the results of his investigations led him to
refer those from the Fanning River Limestone to the Devonian,
those of the Bowen River Coalfield to the Upper Carboniferous or
Permo-Carboniferous, and those from the Tait River to the Cre-
taceous. Twenty-six species of animal remains, chiefly Mollusca,
are described in all, twenty of which are from the Bowen River
Coalfield ; the latter include a fine series of Strophalosiw. The new
species are Protoretepora Koninckii from the Permo-Carboniferous
of Bowen River, and Crioceras Jackii from the Cretaceous ; also
Strophalosia Jukesii from the Carboniferous of New South Wales.
The paper included a list of the localities in which the specimens
were collected, and a full bibliography of Queensland paleontology.
5. On a Fossil Squilla from the London Clay of Highgate, part
of the Wetherell Collection in the British Museum.” By H.
Woodward, Esq., LL.D., F.R.S., F.G.S.
The specimen described is preserved, as usual, in a phosphatic
nodule, and exhibits five well-preserved abdominal segments (xIv.—
xvuiI.), a portion of the carapace, traces of the thoracic appendages,
and the appendages of the twentieth segment preceding the telson.
The abdominal segments increase in breadth posteriorly as in
modern Squille. The species is most nearly allied to a recent
Australian Squilla (unnamed) related to S. Desmarestii. The author
proposed the name of Sguilla Wetherelli for the London-clay fossil.
6. “On WNecroscilla Wilsont, a supposed Stomatopod Crustacean
from the Middle Coal-measures, Cossall, near Ilkeston, Derbyshire.”
By H. Woodward, Esq., LL.D., F.R.S., F.G.S.
The specimen described was found by Mr. E. Wilson, of Not-
tingham, in a nodule of Clay-ironstone. It consists of the four
posterior abdominal somites and the telson. The author discussed
its zoological characters, which led him to regard it as approaching

the Stomapoda rather than the Isopoda. He thought it probable
that Dr. Dawson’s Diplostylus is allied to this newly discovered
form, for which he proposed the name of Necroscilla Walsoni.
7. “On the Discovery of a fossil Squilla in the Cretaceous Depo-
sits of Hakel, in the Lebanon.” By H. Woodward, Esq., LL.D.,
F.R.S., F.G.S.
This fossil Squilla occurs in a collection, chiefly consisting of
fossil fish, but also including several Crustacea and some beautifully
preserved Cephalopods, obtained in the Lebanon by Prof. E. R.
Lewis, of Beirit. The specimens are in a compact cream-coloured
limestone, most of the slabs of which contain examples of Clupea
brevissima and C’, Botte, fragments of Hurypholis Boissiert, and other
fishes. Like the London-clay form, the species seems to be most
nearly allied to the Australian species collected by Prof. Jukes, and
the segments are not ornamented with spines and ridges. ‘The
author proposed for it the name of Squilla Lewisii.
8. “On the Occurrence of a fossil King-Crab (Limulus) in the
Cretaceous Formation of the Lebanon.” By H. Woodward, Esq.,
LL.D., F.B.S., F.G.S.
This was another of Prof. Lewis’s discoveries, and was of much
interest as helping to bridge over the interval between the Jurassic
Limuli of Solenhofen and those now living. The author described
the characters presented by the single specimen, for which he pro-
posed the name of Limulus syriacus.

1, “On a Mammaliferous Deposit at Barrington, near Cam-

The gravel in which these remains were found is about 20 feet
above the alluvial flat by the river Rhee, and is evidently post-

water shells, but not Cyrena or Unio. Remains of the following
Mammalia have been found—Ursus speleus, Meles tawus, Hyena
spelea, Felis speleea, Cervus megaceros, C. elaphus, and another, Bos
primigenius, Bison priscus, Hippopotamus major, Rhinoceros lepto-
rhinus, Elephas antiquus and primigenius—with a worked flint,
almost certainly from the same deposit. The author considers the
abundance and admixture of these remains due to the locality
having been a sort of eddy or pool in the old river. The remains
are described; and the rest of the paper is occupied with a correla-
tion of the gravel with others in the adjoining district, and a con-
sideration of the physical conditions under which it was deposited.

Boyd Dawkins, M.A., F.R.S., F.G.S., and the Rev. J. M. Mello,
M.A., F.G.S., with notes on the Mammalia by the former.
This paper contained the account of digging-operations carried on
in one of the smaller caves of the Cresswell Crags, known as
Mother Grundy’s Parlour. The authors described the occurrence in
the red clay and ferruginous sand of this cave of bones of Hippo-
potamus and the Leptorhine Rhinoceros, proving the existence of
these animals in the wooded valleys of the basin of the Upper
Trent at the time of the accumulation of those deposits ; while at
the same time, so far as the evidence goes, there was an absence of
Paleolithic man, of the Reindeer, and of Horses, while Hyznas were
abundant. In a subsequent period, represented in all the caves by
the Red Sand, the Mammoth, Woolly Rhinoceros, Horse, and Rein-
deer inhabited the vicinity, and were subject to the attacks both of
Hyzenas and of human hunters, whose quartzite implements prove
them to have belonged to the same people whose traces are found in
the river-deposits. In the breccia and upper cave-earth of the larger
caves the existence of the Paleolithic hunter is evidenced by flint
implements resembling those of Solutré, accompanied by implements
of bone and antler. Associated with these was the incised figure
of a horse described in a former paper. The authors finally dwelt
briefly upon the characteristics of the caves in prehistoric and
historic times, and indicated some of the anthropological points of
interest connected therewith.

On the Notodelphyide. By M. L. Kerscuner.
Tue author describes two new genera of the curious Copepod
family Notodelphyide, each including a single species, which he
names Paryphes longipes and Dorsipys uncinata*. He prefaces his
descriptions with some corrections of previous notions as to certain
points in the organization of these crustaceans. He shows that the
brood-chamber, which is usually regarded as contained within the
body-cavity, is formed, in the majority of Notodelphyide, by a dupli-
cature of the integumeut of the body proceeding from the dorsal
surface of the fourth and from the sides of the fourth and fifth
segments, but that in two genera this duplicature is inserted even
upon the second thoracic segment. He further indicates that an

unpaired ovary is present, and that the ova pass in strings into the
oviducts (formerly “ ovaries ”’).
The author confirms a part of Thorell’s observations upon the
connexion of the female generative organs, and, by the discovery of
the hitherto overlooked external genital aperture of the female,
brings back these organs to the general type of the whole order.
In all the males observed he describes an unpaired testis, and
represents the envelope of the spermatophores as secreted by the
wall of the whole of the seminal duct. In the spermatophore itself
he recognizes more layers than Thorell. He describes the type on
which the nervous system is constructed, and, in opposition to Buch-
holz, asserts the presence of olfactory nodes.—Anzeiger Akad.

Notice of a new Pauropod.
Mr. J. A. Ryder described a new myriopod which he had recently
discovered, and which turned out to be nearly allied to the form de-
scribed by Sir John Lubbock under the name of Pauropus. ‘The
specimens which the speaker had obtained were five in number and
had but six segments, fewer than any other known member of the
group, whilst the number of pairs of legs was nine, the same as in
Pauropus, which is very strong evidence that the specimens are
adults. The following characterization of the genus and species
was proposed :—
Hurypauropus spinosus, gen, et sp. nov.
Body-segmeuts six in number, sixth exceedingly rudimentary ;
antenne five-jointed ; legs in nine pairs, equidistant ; tergal sclerites
laterally expanded so as to conceal the legs almost entirely when the
animal is viewed from above, and covered with fine tubercles which
are joined to each other by raised lines ; appressed curved spines are
scattered over their surface in less number, and also fringe their
margins, being disposed at regular intervals; the spines and lines
give the dorsal surface of the little creature a slightly silky lustre
when viewed with reflected light. Colour a delicate light brown.
Mouth-organs the same as in the first-described genus. No evidence
of eyes could he detected. Length j. inch; width about =, inch.
Habitat in Fairmount Park, Philadelphia, east and west of Schuyl-
kill, under decaying wood.
The tergal sclerites are much thicker than in Pauropus, haying
the characteristic brown colour of chitin when viewed with trans-
mitted light. The antenne have the terminal globular hyaline body
with a long pedicle, as in Pawropus pedunculatus. The type is the
most distinct form discovered since the detection of the first known
representatives in England in 1866, and also extends the geogra-
phical range of the family, and does much towards fully establishing
the Pauropoda as a distinct order of myriopods.—Proc. Acad. Nat.

On the Respiratory Apparatus of the Ampullariz.
By M. A. Sasarier.
In a note inserted in the ‘Comptes Rendus ’ of the 12th of May
last, M. Jourdain described the arrangement of the respiratory ap-
paratus of the Ampullarie. Having already occupied myself with
this subject in 1877 *, and having pursued my researches, I am able
to make known some new facts which had escaped the observations
of my predecessors.
The venous blood, returning from the different parts of the body,
divides into three parts :—1, one passes to the right into a cavern-
ous sinus, which accompanies the terminal intestine; this is the
rectal sinus, which is a diverticulum of the general cavity of the
body: 2, the second part comes from the anterior region of the body
(head, pharynx, stomach, anterior margin of the palatine arch) and
forms on the right the proper afferent vessel of the lung, which it
circumscribes to the left and in front ; this vessel presents a double
series of orifices for the afferent branches of the roof and of the
floor of the pulmonary chamber: 3, the third part, which is far
more important, comes together in a large deep vessel with muscular
walls, which soon ramifies on the lower surface and in the thick-
ness of the large gland, to which I have already alluded. From
this network the efferent vessels take their origin, the greater part
of which reunite in a large trunk with muscular walls which carries
the blood to the renal organ: this is the deep afferent vessel of the
renal organ, whichis peculiar to the Ampullarie. The other vessels
which originate from the large gland discharge themselves succes-
sively into a superficial vessel of no great size placed on the posterior
margin of the renal organ, and which is its superficial afferent vessel,
corresponding, in all respects, to the single afferent vessel of the
other Pectinibranchiata. Hence the blood which has traversed the
large gland in a true portal system is not, as M. Jourdain thinks,
mingled with the blood returning from the organs of respiration, to
be immediately poured into the heart, but it does not reach this
latter organ until after it has traversed the renal organ first and
the respiratory organs afterwards.
From the anterior margin of the renal organ there originates, by
successive roots, an efferent vessel of the renal organ, which, after
having anastomosed with the afferent vessel of the same organ, con-
tinues forward on the right margin of the principal branchia, of
which it constitutes the afferent vessel. This vessel receives, in
passing, some affluents proceeding from the rectal sinus.
On the left margin of the branchia, between this latter and the
lung, is a large trunk which terminates at the auricle, and which is
not simply, as M. Jourdain thinks, an efferent vessel of the branchia
and of thelung. ‘This vessel contains, in fact, a series of fissure-like
orifices, which pour into it the blood from the branchia, and two

324 Miscellaneous.
series of circular orifices, of which the upper are the efferent orifices
of the pulmonary arch, and the lower are the afferent orifices of the
floor of the lung. On this floor, in fact, the vessels which originate
from these orifices ramify in a network of which the efferent
branches converge into a large trunk, entirely overlooked by M.
Jourdain, and which, collecting the blood of the whole of the floor
of the lung, empties itself directly into the auricle. From this
results the fact, entirely exceptional in the Pectinibranchiata, that
the auricle receives two totally distinct afferent veins. The one is
branchial and pulmonary, the other exclusively pulmonary. This
is a remarkable peculiarity of the anatomy of the Ampullaria,
which is in connexion with the double respiration of these animals,
and with the alternations in function of the double respiratory ap-
paratus. -
The afferent vessel of the branchia and the proper afferent vessel
of the lung meet in front in such a manner as to form an anterior
arch. The intermediate trunk meets this arcade very obliquely and
under a very sharp angle open to the left. There is thus formed
between the two vessels a valvular spur, which plays an important
part in several respects. When, during sojourn in the water, the
pulmonary respiration and circulation are suspended by the want
of air and the collapse of the lung, the blood of the proper afferent
vessel of the lung, being unable to traverse the pulmonary network,
arrives in abundance at the level of the mouth of the intermediary
trunk, to which it applies the valvule and which it thus stops. It
is thus obliged to pass entirely into the afferent vessel of the
branchia, and, consequently, into the branchia, of which the activity
is thus greatly increased. When, on the contrary, during sojourn
in the air, the collapsed branchia does not act, the blood of the
afferent vessel of the branchia, arriving en masse on the edge of the
spur, there divides into two currents, one of which penetrates into
the proper afferent vessel of the lung, and the other into the inter-
mediary trunk, of which it augments the tension, and which distri-
butes a part of it to the floor of the lung, and reconducts the rest to
the heart. By this means the activity of the pulmonary circulation
is increased during the repose of the branchia. Hence results this
interesting fact, that the Ampullarie, which are Pectinibranchiata
in which pulmonary respiration has made its appearance, have the
respiratory vessels disposed in such a manner that, when this newly-
introduced function suspends its activity, all the blood which should
have traversed the pulmonary network is constrained to traverse
the branchial system, where its heematosis is assured. This curious
arrangement may suffice to explain the preservation of the branchia
in Gasteropoda, in which the lung has attained so remarkable a |
development, and which might have become purely pulmonary
animals.
The distribution of the vessels in the pulmonary walls merits
special mention. They form a double system of portal veins ; that

is to say, the vessels form on their journey two successive net-
works separated by intermediary trunks. This arrangement, a little
less accentuated on the floor than on the roof, added to the pre-
sence of a fine vibratile epithelium on the course of the pulmonary
vessels, proves the active part of this apparatus as an organ of
hematosis.— Comptes Rendus, June 23, 1879, p. 1325.
On the Zoantharia Malacodermata of the Shores of Marseilles.
By M. E. Jourpan.
The anatomical plan of the Actiniade is well known ; it may be
compared to a cylindrical body, furnished at one end with a buccal
aperture surrounded by a circlet of tentacles, and hollowed by a
mesenteric cavity (gastric cavity of the larva), which is connected
with the mouth by an esophageal region of ectodermal origin,
formed by a short and wide tube. Between the cesophageal tube
and the walls of the body are the septa, which terminate freely by
the lower part of their inner margin in the mesenteric cavity.
We have successively studied these different regions in the types
which presented peculiarities appreciable by the naked eye, and we
will here give a summary of the principal results that we have
obtained.
The walls of the body contain three layers—an external cellular
layer or ectoderm, a fibrous mesodermic layer, and an internal cel-
lular layer or endoderm.
The ectoderm is formed of glandular elements, vibratile cells,
epithelial elements, which are probably sensitive (analogous to
those of the chromatophorous sacs of Actinia equina), and, lastly,
neuro-muscular elements, which we have distinctly observed in the
above species. In Phellia this cellular layer secretes a viscous
mucus, which, by agglutinating fragments of all sorts, gives a
peculiar aspect to the body.
In Bunodes the glandular elements of the ectodermic layer group
themselves together and form the little organs which adorn the
column of these animals.
Cerianthus is remarkable for the structure of its mesodermic layer,
and thus constitutes a distinct type among the Zoantharia Malaco-
dermata. This layer is composed of a thick muscular region in-
cluded between two planes of connective tissue. The longitudinal
muscular fibres composing it are smooth and arranged in radiating
lamine. Beneath the inner fibrous plane there exists another layer
of circular fibres.
In the Actinie the mesoderm is represented by laminz of con-
nective tissue, clothed internally by a layer of circular muscular
fibres, which occur throughout the height of the column. Calliactis
possesses a fibrous layer of exceptional thickness and density, tra-
versed by persistent pores, and sprinkled in its upper part with
Ann. & Mag. N. Hist. Ser. 5. Vol. iv. 23
326 Miscellaneous.
numerous islets of annular muscular fibres which must act after the
fashion of a sphincter.
The endoderm is composed of a cellular layer, which covers the
inner surface of the mesoderm and extends over the septa.
The structure of the tentacles is similar to that of the walls of
the body. These organs, however, are characterized by the pre-
sence of a layer of longitudinal muscular fibres situated beneath the
ectoderm.
The septa originate from the mesodermic layer of the column.
Their axis is a fibrous tissue covered with a layer of longitudinal
muscular fibres. Upon one of its surfaces each septum bears a
series of longitudinal folds, the totality of which represents a sort
of fibro-muscular bundle.
The wsophagus, resulting from the turning back of the two pri-
mitive lamella, necessarily presents the structure of the wall of the
body. The exterior cellular layer contains peculiar glandular
elements.
In Cerianthus and the Actinie the reproductive elements origi-
nate in a sort of doubling of the fibrous layer of the septa—that is
to say, in the mesodermic region.—Comptes Rendus, August 25,
1879, p. 452.
Notes on the Marriage-flighis of Lasius flavus and Myrmica lobi-
cornis. By the Rev. H. C. McCoox.
The author remarked that the first-named ant is one of the most
familiar objects in nature. Its small dusky-yellow workers may be
seen in every American lawn, walk, field, and yard, throwing up
their fragile moundlets of sand pellets, and swarming upon particles
of fruit, crumbs, bones, dead insects, and all manner of sweets. It is
quite cosmopolitan in its distribution, and is well known in Europe.
The following observation of the annual marriage-flight of the sexes
was made September 5, 1878, in the vicinity of Philadelphia. The
nests observed were located directly in and on the grassy border of
a trodden path ina farmyard. At4p.m. the males and females
were seen coming out and re-entering the gate, amid great excite-
ment on the part of the workers. The females particularly were
followed by workers who “teased” them occasionally by gently
nipping them with their mandibles. The flight of the young queens
was, with few exceptions, made from the top of stalks of grass,
where they clung for several minutes, poising themselves, spreading
their wings, and swaying up and down. LEven to these elevations
the workers followed them, hastening their flight by occasional
“‘ nips.” When the queen rose in flight, there was no evidence of
feebleness or inexperince, except, in some cases, a slight tendency
to a zigzag course for the first few yards. ‘The flight was then, and
in most cases from the very first also, strong and in a straight
Miscellaneous. 327
course. The insect first rose to a height of about 20 feet, which
was soon increased to 40, 50, and even 60 feet (estimated) ; and this
latter height was maintained until the form was lost to sight. The
author was able to follow the ants in several instances to a distance
of more than 300 feet before they disappeared, at which time they
gave no sign of alighting. Some were seen to alight at the distance
of 60 and 80 feet; others flew into a large buttonwood-tree within
30 feet of the nest.
The flight was in every case solitary, and was in all directions,
although generally in the direction of the breeze. The males were
in the meantime continually taking flight, urged thereto by teasing
workers, each separately, and wholly independent of other males
and of the females, as to the time and direction of flight. This fact
led Mr. McCook to infer that the pairing of the sexes must have
occurred within the nest before departure therefrom. Except in
the case of those individuals who lit upon the buttonwood-tree,
there appeared no opportunity for a meeting after flight. There
was nothing in all the facts to suggest the idea of a future consort.
The same feature of independent and solitary flight of the sexes
had been observed in the swarming of the shining slave-maker,
Polyergus lucidus. This is in marked contrast with the habit of
some other ants as illustrated in an observation subsequently
given.
Before taking flight the Z. flavus females spent some time in
combing and cleansing themselves. A female was placed among
the workers of another nest not more than a yard distant from her
own, in order to test the treatment of an aliens She was immedi-
ately attacked fiercely, and would no doubt have been soon killed
had she not been removed. In two formicaries from which the
above marriage-flight occurred, it was observed that the doors were
closed about half-past four p.m. by bits of dry grass and pellets of
soil. ‘They so remained during the night, or at least were found
closed in the morning, ‘Three days thereafter several males were
found nestled under a chip by the roadside. As soon as the chip
was turned up, two of these were seized by a couple of prowling
ants of the species Tetramorium cespitum and Formica Schaufussi,
and carried off as prey, a suggestion of the common fate of emmet
masculines.
Mr. McCook’s attention had been called to an articlein a Hollidays-
burg (Pennsylvania) journal, which reported a remarkable swarm of
ants that had crossed that town on the 18th September, 1876. He
immediately wrote to the Rey. D. H. Barron, a citizen of the place,
and a gentleman of intelligence and prudence, giving certain points
which it was desirable to ascertain. The ants, in the course of
their flight, had come into contact with the mechanics at work upon
the tower of the new court-house, whom it was reported they had
assaulted vigorously. Mr. Barron visited these men, and, after a
careful interview communicated the following facts:—The flight
actually occurred substantially as reported ; the day was clear, warm,
328 Miscellaneous.
and calm; the ants came between 10 and 11 a.m., from the direc-
tion of the Chimney Rocks, a ridge of the mountain on the south-
east of the town. As to numbers, the answers of the men were as
follows :—* So thick you could hardly see through them ;” ‘‘swarms;”
‘‘ about 30,000!” The ants struck the building at the height of
about 120 or 125 feet, and certainly assaulted the men. Whether
the attack was a bite or a sting they could not tell ; but it was some-
thing very uncomfortable, and they would not like to have it re-
peated. The ants were of two sizes—some larger, some smaller.
One of the men had saved some specimens, which were sent to Mr.
McCook, and proved to be the males and females of Myrmica lobi-
cornis, Nylander. These ants can inflict a painful sting, but pro-
bably attacked the workmen simply in self-defence; that is, the
men happened to obstruct their flight, and naturally vigorously
brushed off the insects who lit upon them, who, in turn becoming
irate, applied their stings. Such avast horde as this swarm con-
tained must have been composed of the winged inmates of many
formicaries on the mountain-side. This is quite in contrast with
the solitary flight of the Zasiws flavus as previously described.
The pairing of the sexes was probably in the air, or after alight-
ing, as in the case of the agricultural ant*. Mr. McCook had
taken ants of the same subfamily Myrmicide while they were in
the act of pairing in the air.
In connexion with the above notes on the queen-life of ants, he
presented an observation reported to him by Mr. Jos. Wilcox.
This gentleman had seen a colony of some species of Camponotus
occupying a large dead cypress tree standing in the midst of a cypress-
swamp in Florida, at least 600 feet from the shore. The tree was
wholly isolated from the land and from all surrounding vegetation,
except another fallen cypress tree which leaned up against it. Evi-
dently a fertilized queen had at some time flown from the land to
this tree, where she had established the colony. The fact is inter-
esting as indicating the origin of formicaries from single queens, as
myrmecologists have supposed to be frequently, if not commonly,
the case—further as showing the ability of a large number of ants
(this nest was reported to consist of vast numbers) to maintain
active life under quite circumscribed environment. ‘The insects
sheltered in such numbers by old trees may have furnished a large
portion of the food supply. The specimens brought by Mr. Wilcox
were taken from a colony on the land, which he supposed to be
identical with the swamp-tree nest, and were examples of Cam-
ponotus esuriens, Smith—Proc. Acad. Nat. Sci. Philad., April 29,

XXX VII.—Additions to the Amphipodous Crustacea of New
Zealand. By Grorce M. THomson, Dunedin.
[Plate XVI.]
A GREAT boon was conferred upon working naturalists in this
colony by the publication, in 1876, of a Catalogue of the
Stalk- and Sessile-eyed Crustacea of New Zealand, by Mr. E.
J. Miers, of the British Museum, under the auspices of the
Colonial Government. Information on the subject was there
collected together which had previously been obtainable only
by reference to expensive and difficultly obtainable works ;
and though the catalogue was necessarily imperfect, it gave
a good starting-point to those engaged in working up this
branch of the New-Zealand fauna. Naturally enough, chiefly
the larger Crustacea belonging to the Brachyura and Macrura
had been obtained by earlier collectors, and the list of them
is tolerably complete. It is to the Isopoda and Amphipoda
that additions will chiefly be made, these tribes being well
represented in our seas.
Mr. Miers has enumerated fifteen species of Amphipoda in
his catalogue, all of which, with the exception of Phronima
novee-zealandie, Powell, were previously described in Spence
Bate’s catalogue of Amphipodous Crustacea in the British
Museum. Ofthese species, Zalitrus (?) nove-zealandie, Dana

Wellington made some additions to the local crustacean fauna,
including the following Amphipods—Caprella lobata and *C.

and smooth. Pereiopoda subequal, fifth pair rather the
longest ; setee numerous and strong, not exceeding the dia-
meter of the articulations to which they are attached. 'Telson
conical, tipped with a few slender sete.
Female differs from the above only in the greater width of
the pereion, and in having the second gnathopoda relatively
smaller, rounder, and wanting the plumose cilia. Length
*25 inch.
Hab, Dredged along with the preceding species in Dunedin
Harbour in 4—5 fathoms, among Sertularve and seaweeds.
This species differs from the generic characters of Cyrto-
phium in possessing an appendage on the superior antenne ;
but as it agrees in every other respect, I do not feel justified
in placing it in a new genus. It comes nearest to C. brasi-
liense, obtained by Dana in the harbour of Rio Janeiro.

CAMBRIAN SystTEM.—Although the fact of the existence of
Cladophora in the Upper Cambrian rocks has been admitted
by paleontologists since Salter’s discovery of Dictyonema
sociale in such abundance in strata of this age in Merioneth-
shire, it is only within the last few years that the presence of
Rhabdophora or true Graptolites in these ancient deposits
has been placed absolutely beyond question. Kjerulf, indeed,
figured a well-marked Dichograptus (Bryograptus) trom the
Alum-shales of Christiania in his ‘ Veiviser,’ as early as 1865 ;
but its exact horizon is even yet doubtful. Its true Cambrian
age, however, is rendered highly probable by Linnarsson’s
more recent discovery of Dichograptus tenellus &c. in the
highest Olenus-beds of Westrogothia*, and an allied form in
the Dictyonema-schists of Scania. These strata correspond
to the highest portions of the Lingula-flags of Wales, and
are unequivocally of true Cambrian age.
The question of the existence of Rhabdophora in the Upper
Cambrian of Britain has also been satisfactorily set at rest by
the interesting researches of Dr. C. Callaway. This careful
observer detected Graptolites in the Shineton (Upper Cam-
brian) shales of Salop as early as 1873 ; and in the following
year examples of Bryogruptus and Clonograptus from these
rocks were forwarded by him to me for identification; and I
recognized at once their striking similarity to the forms figured
from the Swedish Cambrian by Kjerulf and Linnarsson.
Within the last few months Dr. Callaway has discovered
fragments of the first of these genera in the Cambrian rocks
of the Malvern Hills.

ORDOVICIAN OR LOWER SrLurtan System.—Notwithstand-
ing the great additions made of late years to our knowledge of
the fossils of the rich graptolitiferous zones of the Llandovery
and Wenlock formations, Salter’s well-known generalization that
Murchison’s Lower Silurian system is most prolific in Grapto-
lites remains practically undisturbed. The Arenig formation
also, though it can no longer be defined as the birthplace of
the family, must still be acknowledged as its metropolis; for
if we have respect to the abundant extra-British forms de-
tected in this formation, it must be conceded that “ nowhere
else are there so many species and such complex forms” *.
This may, it is true, be owing to the fact that not only in
Britain, but also in Europe and America the rocks of Arenig
age are essentially dark carbonaceous shales or schists more
or less graptolitiferous throughout; while the succeeding forma-
tions are marked by a much greater development of sandstones
and limestones, from which, as a rule, Graptolites are absent.
Nevertheless, even where black shales crowded with Grapto-
lites do occur in these more recent formations, we never find
so great a variety of types as upon any single horizon in the
Arenig; and it may be that the Rhabdophora (like the
Cladophora) had their culmination at or near the commence-
ment of the Arenig, the loss, especially in genera, being very
rapid as we pass upwards into the Llandeilo and Bala.
Arenig Formation.
The only Welsh rocks belonging to this formation as yet
carefully searched for Graptolites are the Arenig rocks of the
neighbourhood of St. David’s, familiar togeologists through
the extended researches of Dr. H. Hicks. The three sub-
groups into which the strata of this age are there divisible all
yield Rhabdophora in some abundance. ‘The forms recog-
nized by Mr. Hopkinson and myself include F :—
I. Lower Arenig.
Didymograptus extensus, Hall. Phyllograptus stella, Hopk.
pennatulus, Hail. Trigonograptus truncatus, Lapw.

Some of the same forms occur in the corresponding Arenig
rocks of Merionethshire. In the Jermyn-Street Museum the
following forms are labelled as having been collected from the
Upper Arenig of Tyobry near Tan-y-Bwylch * :—
Diplograptus tricornis, Carr. Glossograptus ciliatus, Em.
bimucronatus, Wich. Diplograptus foliaceus, Murch.
Climacograptus confertus, Lapw. angustifolius, Hall.
The Arenig rocks in the neighbourhood of Shelve yield
Rhabdophora in some abundance. From the lowest zones
near the Bog Mine I have collected forms of Phyllograptus,
Didymograptus, and Trigonograptus. In the Middle Arenig
near Shelve church Mr. Hopkinson has detected | Didymo-
graptus patulus, Hall, and Clematograptus implicatus, Hopk.
I have found some of the same forms at Ladywell Mine, Dis-
gwylfa &e. From the Upper Arenig of Ritton Castle I have
collected Didymograptus Nicholsoni, Lapw., and D. patulus,
“Hall. Didymograptus constrictus, Hall, is not uncommon in
similar strata near Snailbeach.
Lake District—The Arenig rocks of the Lake District
include the Skiddaw Slates of Sedgwick. Little is yet known
with certainty with respect to their proper physical and pale-
ontological subdivisions. At present it is only possible to
regard them, with Prof. Nicholson, as forming two main
groups —a lower group of dark flagstones and shales, and an
upper group of black shales and mudstones. Their Grapto-
lites have been made the subjects of special memoirs by Salter
and Nicholson; but the remarkably intertwined character of
the two supposed subfaunas renders it more than probable that
we have yet much to learn with respect to the systematic
places of the several fossiliferous horizons.
From the Lower Skiddaw Rocks the following species have
been collected + :—
Loganograptus Logani, Hall. Schizograptus reticulatus, Nich.
Temnograptus multiplex, Nich. Ctenograptus annulatus, Nich.

The various species of Monograptus (Graptolithus*) quoted
by Salter and others from the Skiddaw series are almost cer-
tainly merely fragments of compound genera. The Grapto-
lithus latus of M‘Coy + was certainly of this nature; and the
Graptolithus tenuis, G. Nilssoni, and G. sagitiar‘us of Salter
may with safety be assumed to have had a similar origin.
His Didymograptus sextans (Dicellograptus?) is equally dubi-
ous. His Diplograptus pristis could not have been Hisinger’s
species, but was possibly Diplograptus serra (Brongn.) or
some allied biserial form.
From the Upper Arenig rocks of Ellergill &c. Professor
Nicholson has collected + :—
Trigonograptus lanceolatus, Nich. Didymograptus geminus, His.

Distribution of the Rhabdophora. 337
Dr. Tornquist has identified, in addition, Didymograptus
extensus, Hall, Didymograptus affinis, Nich., and Phyllo-
graptus typus, Hall. To these Mr. Linnarsson has recently
added representatives of Didymograptus v-fractus, Salt., Tri-
chograptus multiplex, Nich., Diplograptus Hopkinsont, Nich.
The dark shales that succeed to the Cambrian rocks of the
neighbourhood of Christiania in Norway, and include the
local representative of the Orthoceras-Limestone of Sweden,
have long been known to be graptolititerous. A few of the
Rhabdophora of these beds have been figured by Boeck + and
Scharenberg ¢; but the horizons of the species are unknown.
The forms named below may be easily identified upon their
plates. Those in all probability restricted to the higher zones
I have marked with an asterisk.

America.—As pointed out by Professor Selwyn §$, the main
mass of the Point-Levis or Quebec group of the valley of the
St. Lawrence lies at the very base of the Ordovician or Lower
Silurian system, and is thus, broadly speaking, synchronous
with the British Arenig rocks. Its Rhabdophora have been
long familiar to the eyes of paleontologists in the beautiful
plates of Hall’s classical memoir on the Graptolites of the
Quebec Group. It may be that the more ancient of the
strata from which his specimens were procured may even-
tually be proved to be of true Cambrian age. In the mean-
time, however, no division of these forms can be attempted.
The species figured by Hall from Point Levis include :-—

From similar beds at Orleans Island, Gros Maule, and the
river St. Anne, Hall describes :—Didymograptus similis, H.;
Tetragraptus fruticosus, H.; T. Headi, H.; Dichograptus
octonartus, H.; Clonograptus Richardsont, H.; and Phyllo-
graptus Anna, H.
Of these Quebee forms Tetragraptus Headi, H., T. bryo-
nites, H., Phyllograptus angustifolius, H., and P. typus, H.,
were subsequently detected in corresponding strata on the
coast of Newfoundland *, where their association with Crus-
tacea &c. of Tremadoc and Arenig types, as at Point Levis,
is demonstrative of their systematic place at or near the base
of the Ordovician.
Australia.—Mr. R. Etheridge, Jun., and Professor M‘Coy
have recently described a small collection of Rhabdophora from
the lowest Ordovician rocks of Australiat, which is remark-
able for its general identity in facies with that of the Arenig
rocks of England and Canada. ‘The species figured are pos-
sibly :—
Loganograptus Logani, /Zall. Dichograptus octobrachiatus, Hall.
Goniograptus Thureaui, A/‘Coy. Phyllograptus typus, Had.

together with indeterminable species of Climacograptus and
Diplograptus.
Llandeilo Formation.
Dr. Hicks breaks up the Llandeilo formation of Wales into
three portions, the well-known limestones and calcareous
shales of Llandewi Felfry and Llandeilo forming the central
member. ‘This arrangement, though not universally applica-
ble, may possibly be the natural one in the southern districts.
There the Lower Llandeilo consists of dark carbonaceous shales
and thick beds of coarse sandstones, with occasional igneous
rocks of contemporaneous age, the Middle Llandeilo of cal-
careous flagstones, and the so-called Upper Llandeilo of soft
dark grey flags and mudstones, forming a gradual transition
into, and only doubtfully separable from, the overlying Bala
formation.
In the Lower Division, as seen to the west of Shelve, I
have collected Didymograptus Murchisoni, Beck, in some
abundance, and in corresponding strata below as well as

amid the voleanic rocks of the Gelli Hills near Builth. In
the dark Llandeilo shales of Pwllacca near Llandeilo I have
seen the smaller varieties of Didymograptus Murchisoni in
myriads, together with Diplograptus foliaceus, Murch., Cli-
macograptus celatus, Lapw., and indeterminable forms of
Didymograptus. Didymograptus Murchisoni, Beck, is quite
as abundant in the black shales below the Limestone of
Llandewi Felfry near Whitland, associated with Dédymo-
graptus Nicholsoni, Lapw., Goniograptus, sp., Climacograptus
confertus, Lapw., Diplograptus tricornis, &e. The forms
recognized by Mr. Hopkinson and myself* in the Lower
Llandeilo zone of Abereiddy Bay include
Didymograptus euodus, Lapw. Diplograptus foliaceus, Murch.
indentatus, Hall. tricornis, Carr.
—— Murchisoni, Beck. Dicellograptus moffatensis ?, Carr.
and some others.
In the Middle Llandeilo of Abereiddy Bay are found
Dicellograptus, Diplograptus foliaceus, Murch., and D, tri-
cornis, Carr. In the corresponding strata of Builth Road
and Wellfield, Radnorshire, I have detected
Dicellograptus patulosus, Lapw. Diplograptus tricornis, Carr.
Coenograptus gracilis ?, Hall. Climacograptus celatus, Lapw.
Diplograptus foliaceus, Murch.
A fine example of Dicranograptus formosus, Hopk., from
these beds at Castell is in the Jermyn-Ntreet collection (Case
lv. 3s). Rocks of corresponding age at Meadowtown near
Shelve have yielded me Diplograptus foliaceus, Murch., and
D. dentatus, Brongn.
The Upper Llandeilo rocks of Abereiddy Bay have, up to
this time, proved barren of Graptolites. From the Upper
Llandeilo of Hagley, near Chirbury, I have collected Diplo-
graptus foliaceus, Murch., and Climacograptus Scharenbergi,
Lapw. From the Upper Llandeilo of Llandrindod Wells Mr.
Hopkinson sent me, some years ago, Climacograptus Scharen-
bergi, Lapw., C. celatus, Lapw., and Dicellograptus mof-
fatensis, Carr. From the same rocks near that town I have
this summer collected Diplograptus tricornis, Carr., D. folia-
ceus, Murch., Climacograptus celatus, Lapw., C. perexca-
vatus, Lapw., C. Scharenbergi, Lapw., and species of Dicel-
lograptus aud Lastograptus.

During the progress of the Geological Survey of North
Wales Mr. Salter detected Graptolites in the deep-seated
schists of Tiddyn Dicwm, near Tremadoc. From their appa-
rent stratigraphical position he assigned them to the general
horizon of the Arenig formation. There can be little doubt,
however, that they are actually of Llandeilo age. ‘The speci-
mens from this locality preserved in the Jermyn-Street
Museum, or figured in the ‘Geology of North Wales’*,
include Dicranograptus ramosus, Hall, Diplograptus tricornis,
Carr., Climacograptus Scharenbergi, Lapw., and C. bicornis,
Hall. I recognized the same species in a fine collection made
by Mr. Hopkinson from this locality in 1873, together with
the following additional species :—
Didymograptus, sp. Diplograptus angustifolius, Hall.
Glossograptus Hincksi, Hopk. Dicellograptus sextans (?), Hall,
Diplograptus dentatus, Brongn. Diplograptus Whitfieldi, Had.
Treland.—The only graptolitiferous strata in Ireland that
ean with certainty be assigned to the Llandeilo formation
are the schists of Bellewston Hill, County Meath, whence
Mr. Baily procured Didymograptus Murchisont, Beck, in
association with Diplograptus foliaceus, Murch., and other
forms fF.
Sweden.—The black shales that overlie the Orthoceras-
Limestone of Sweden, and are known as the Dicranograptus-
or Middle Graptolite-schists, fall into two tolerably distinct
paleontological groups. The lower group (Murchisoni- or
geminus-schists) is marked by the presence of Didymograptus
geminus, His., and several allied species; and it may there-
fore be roughly paralleled with our British Llandeilo. Ac-
cording to the most recent researches of Mr, Linnarsson f its
lowest beds contain representatives of the British forms
Phyllograptus typus, Hall, Diplograptus Hopkinsont, Nich.,
and Diplograptus tricornis, Carr. ‘These pass up into a
group of dark shales with Didymograptus geminus, His. ; and
the Llandeilo group is terminated by beds with Glossograptus

Acme Foliniana.
Testa turrito-elongata, imperforata, cornea, levis et nitida; spira
subrecta, paululum prope apicem obtusum eversa; anfract.
6 aut 6} (rarissime 7), convexiusculi, sutura distincta separati,
interdum inferne linea incisa (more Eulimidarum) circumdata ;
apertura subverticalis, subquadrangularis, marginibus callo levi
junctis; columellaris subrecta; peristom. album, percrassum,
_ duplex.
Typi anfr. 6°5; long. 5°5, diam. 1°75; apert. alt. 1°5, lat. 1:1
millim.
This was an exceedingly abundant form, often in a perfect
state of preservation, at three different levels ; a few specimens
had seven well-developed whorls, the others 6 or 63, increa-
sing very gradually and regularly, moderately convex, the last
two approximately of equal breadth ; apex blunt and obtuse,
the apical whorls with a slight inclination to the right (away
from the axis of the shell) ; perfectly smooth, polished, shi-
ning, of a more or less paie horny colour, sometimes so trans-
parent that the columella can be traced from the apex to the
base ; suture distinct, with a more or less obsolete incised
line close below it, as in many species of Hulima &c. ; aperture
a trifle everted, subquadrate, with a remarkable, pure white,
callous rib close to the peristome, imparting a duplex appear-
ance to the latter; a thin callosity joms the margins.
I have much pleasure in naming this, the giant of its
genus, after my friend the Marquis de Folin of Bayonne,
whose researches connected with minute marine species are
so highly valued and appreciated.

Var. emaciata, nov.
This is a dwarf form, apparently varying in every spe-
cimen, and of which it seems to me impossible to grasp
any thoroughly constant character. Taking an extreme spe-
cimen, it is distinguished by its smaller size, by the more
regularly turreted spire being quite upright, 6 whorls, of
almost equal size, slightly more convex, especially the last,
which is also proportionally very short; aperture smaller, a
trifle more vertical and scarcely everted; callosity joining
margins well developed; peristome does not present the
duplex appearance of the preceding, except at the columella.
Rare in middle deposit only.

Var. pachystoma, nov.
(An potius A. pachystoma, sp. nov. ?)
This, unlike the preceding, is an exceedingly well-marked
and distinct form, unmistakable at a glance. I think it ex-
tremely probable Mons. Bourguignat is correct in regarding
it as a distinct species. It can be known from the typical
form by its much less distinct suture, by the shorter, less
elegantly and regularly turreted spine, composed of only six
more rapidly imcreasing whorls, the apical two compressed,
the others scarcely convex, almost cylindrical, especially the
last, which is proportionally much longer, the antepenulti-
mate one much broader than the others (not the case in type
form) ; the apical portion of the spire considerably more
diverted from the axis of the shell, with the aperture very
much everted, imparting a still stronger resemblance to cer-
tain species of Hulima; the thick, white peristome is sur-
rounded by a still more callous rib, especially noticeable at its
termination, about the middle of the columella, which is
slightly oblique; the duplex character of this outer lip is still
more distinctly and clearly marked. This form was by no
means uncommon, though much less abundant than typical
A. Foliniana, with which it was associated.

(Bt AV IL fe. 1.)
Adult male, length very nearly } of an inch.
The colour of the cephalothorax, falces, maxille, labium,
and sternum is a clear but darkish yellow-brown ; the legs
and palpi are of a paler hue, and the abdomen is blackish
olive-brown. ‘The general convexity of the cephalothorax is
somewhat depressed ; but the caput is well rounded on all
Neriéne rasa, sp. n.
344 Rey. O. P. Cambridge on some
sides, and the profile of the clypeus (which considerably ex-
ceeds in height half that of the facial space) continues the
curve of the profile of the occiput; the profile line behind the
occiput exhibits a very slight depression ; on the caput and
clypeus are some prominent hairs.
The eyes are small, and, excepting the fore-centrals, which
are very small, are of equal size; those of the hind-central
pair are considerably nearer together than each is to the hind-
lateral eye on its side, the interval being no more than an
eye’s diameter, which is also the same interval as that which
separates them from the fore-centrals ; those of each lateral
pair are placed obliquely on a tubercle ; the fore-centrals are
dark, indistinct, and contiguous to each other.
The legs are of tolerable length and rather slender ; their
armature had been almost entirely denuded, but it appears to
have consisted of hairs only.
The palpi are short ; the radial joint is stronger, but scarcely
longer, than the cubital, both being very short; the former
spreads out a little in front, but has no projection or apo-
physis; it is furnished with some bristly hairs, the longest
and strongest of which are on the outer side; the digital joint
is of moderate size, and has a strong lobe or prominence to-
wards its hinder extremity on the outer side; the palpal
organs are moderately complex; at their base on the outer
side is a prominent, almost circularly curved, corneous process,
and at their extremity are two or three small, blunt, projecting,
corneous points.
The falces are long, strong, and greatly inclined back-
wards to the labium ; they are also a little divergent at their
extremities.
The abdomen is of tolerable size; its shape is a regular
oval, its surface glossy and very sparingly clothed with hairs ;
and it projects a little over the base of the thorax.
~ This spider is allied to Neriéne Huthwaitii, Cambr., which
it resembles very much in general colouring and appearance ;
but it may easily be distinguished by the much shorter radial
joint and much larger digital joint of the palpus ; the struc-
ture also of the palpal organs is entirely different.
A single example was sent to me for examination by Count
Keyserling, by whom it was found at Dux.
Neriéne Keyserlingii, sp.n. (Pl. XVII. fig. 2.)
Adult female, length + of an inch.
The whole of the fore part of this spider, including the legs
and palpi (which are a little the palest), is of a clear yellow
colour ; and the abdomen is pale straw-coloured. The cephalo-
new Species of Araneidea. 345
thorax is of a rather flattened form; the profile line forms a
slightly curved slope to the eyes, the depression behind the
occiput being exceedingly slight. The normal grooves and
indentations are fairly marked, and are also indicated by con-
verging lines of a dusky hue.
The eyes are of tolerable size and not very unequal; they
are rather closely grouped ; those of the posterior row are
equidistant from each other, being separated by a central-
eye’s diameter, each of the central eyes being also separated
by a similar space from the fore-central eye opposite to it.
Those of each lateral pair are contiguous to each other, and
are seated obliquely on a black tubercle; those of the fore-
central pair are on a large black spot, and are separated from
each other by nearly half a diameter.
The legs are moderate in length and strength (4, 1, 2, 3),
furnished with hairs, and a very few slender prominent
bristles.
The falces are long, strong, very prominent towards their
base in front, a little divergent, and armed with strong sharp
teeth on the inner sides, a row of five (the strongest) being
placed along the outer edge, and three along the inner edge
of the groove in which the fang lies when at rest. On the
outer sides in front are some minute piliferous tubercles ar-
ranged in two or three longitudinal lines.
The mazille are long, strong, somewhat obtusely pointed
on the inner extremities, and inclined towards the labium,
which is of a semicircular form.
The abdomen is oval, broadest behind, and projects over the
base of the cephalothorax ; it is of a pale straw-yellow colour,
thinly clothed with fine hairs, and marked with four small,
round, red-brown, impressed spots near the middle of the
upperside, forming a trapezoid, whose posterior is longer than
the anterior side; a sooty-black broken: stripe bisects the
upperside in a longitudinal direction, the hinder part being
formed of two elongate arrow-head markings, following each
other in close contact, the posterior one merging in a large
sooty-black patch some little distance above the spinners. It
is probable that in a series of examples some variations in this
pattern would be exhibited. The genital aperture is small
and characteristic in form, but has no prominent process con-
nected with it; just in front of the spinners is a curved lip-
like fold in the integument, having every appearance of being
the aperture leading to one or two spiracles (breathing-
organs).
Two examples of this fine and distinct species were com-
prised in the collection of spiders received for examination

many ; but the precise locality is unknown to me.
Neriéne tracunda, sp.n. (Pl. XVII. fig. 3.)
Adult male, length slightly over 1 line.
The cephalothorax is of a dark yellow-brown colour, and of
a somewhat oblong-oval form, broad at the fore part, and the
lateral constriction on the margins, at the caput, exceedingly
slight. ‘The profile line forms a tolerably even, though very
slight curve ; the ocular area slopes forwards; and the clypeus,
which projects a little, is less in height than half that of the
facial space.
The eyes are all seated on tubercles; those of the lateral
pairs rather strong; they are not very large or greatly dif-
ferent in size, those of the anterior (or fore-central) pair, which
are a little the smallest, are separated by a small but distinct
interval, those of the hind-central pair are divided by rather
less than a diameter’s interval, that which separates each of
them from the hind-lateral eye on its side being about equal
to a diameter. ‘The curves of the two rows of eyes are
as nearly as possible equal, but directed in opposite directions,
and enclosing a transverse oval space; those of each lateral
pair are placed very slightly obliquely.
The legs are rather long, slender, 4, 1, 2, 3, furnished with
hairs, and one or two erect bristles only, and of a pale orange-
yellow colour.
The palpi are short; the digital and radial joints brown,
the rest similar in colour to the legs. The cubital and radial
joints are very short; the latter is the strongest and has its
fore extremity on the upperside produced, but very slightly,
into a somewhat pointed termination ; and there is also a pro-
minent point on the outer side: the digital joint is of moderate
size ; it has a small, blunt, somewhat tooth-like projection at
its base; and on its outer side is a prominent, somewhat ele-
vated subangular lobe. The palpal organs are complex and
well developed, but present no very noticeable processes.
The falces are powerful, prominent near their base in front,
divergent, and greatly cut away on the inner side of their
fore half—so far as I could see, destitute of teeth, excepting a
bluntish one at the extreme inner point near the insertion of
the fang. ‘The outer sides in front are furnished with minute
piliferous tubercles. The colour of the falces is similar to
that of the cephalothorax.
The maxille are like the falces in colour; they are strong,
moderately long, rounded on their outer sides and at the ex-
tremities, and inclined towards the labiwm, which is short,’
new Species of Araneidea. 347
somewhat roundly truncated at the apex, and of a dark black-
brown hue.
The sternum is similar to the labium in colour.
The abdomen is narrow oviform, glossy and black, and
thinly clothed with hairs.
A single example of this spider, which is allied to Nerdéne
subtilis, N. conigera, and N. innotabilis, Cambr., was received
from Count Keyserling, by whom it was found in Liivland.
Gen. WALCKENAERA, Bl.
Walckenaéra nasuta, sp.n. (PI. XVII. fig. 4.)
Adult male, length ; of an inch.
The cephalothorax, legs, palpi, and falces are of a light
rather orange-yellow colour, the tibie, tarsi, and metatarsi
of the legs being a little the palest, and the caput slightly suf-
fused towards the fore part on the upperside with a dusky
brownish hue. The caput is elevated, and the fore extremity
of the upperside projects forwards in a somewhat curved
and tapering form, terminating in a round knob connected
with the main portion by a narrow neck-like constriction, and
giving it a very nose-like appearance; the fore part of the
caput, as well as the knob, is furnished pretty thickly with
hairs; there are also a few shorter ones along the upperside of
the caput, directed slightly backwards. The thorax is a little
gibbous about the middle of the upperside.
The eyes are small, seated on black spots, and in the usual
four pairs ; the lateral pairs are one on each side, towards the
fore extremity of the caput, at about the thoracic level; the
fore-central pair is in front, between and on a level with the
laterals ; the eyes of these three pairs are respectively con-
tiguous to each other, while those of the hind-central pair are
wide apart, one on each side of the produced part of caput, a
little behind the neck or constriction.
The legs are slender, not very long, furnished with ordinary
hairs, and a few erect ones on the upperside of the tibie and
metatarsi.
The palpi are moderately long ; the cubital joint is rather
long and slightly clavate; the radial joint is short, but has
its fore extremity produced into a long, tapering, twisted,
sharp-pointed, rather prominent apophysis. The length of
this joint and its apophysis is about equal to that of the
cubital joint. The digital joint is of moderate size; and the
palpal organs are prominent and rather complex, but have no
very remarkable processes.
The abdomen is oviform ; it projects but slightly over the

base of the cephalothorax, and is jet-black, thinly clothed with
hairs.
A single example, in excellent condition, of this very
remarkable little spider was kindly sent to me, from Lisbon,
with numerous other spiders, by Mr. H. O. Forbes.
Walckenaéra congenera, sp.n. (Pl. XVII. fig. 5.)
Adult male, length 1 line.
The cephalothorax is of a deep rich black-brown colour, the
legs orange, and the abdomen jet-black. The caput is elevated
into a moderate-sized, well-rounded eminence ; the height of
the clypeus is a little over half that of the facial space; it
slopes forwards following the same line as that of the fore
protile of the eminence on the caput. The upper (or hind-
central) pair of eyes are seated on the fore part of the upper-
side of the eminence, and are separated by an eye’s diameter.
The legs are slender, of moderate length, 1, 4, 2, 3, and
furnished with hairs only; if any other armature was ever
present it had been rubbed off before the example came to
hand.
The palpéare moderately long, slender, and of a yellow colour,
excepting the digital joint, which is dark yellow-brown. The
cubital joint is slightly clavate and bent downwards ; the radial
joint is stronger than the cubital, and has its fore extremity, on
the upperside, produced into a long, somewhat tapering, and
curved apophysis, whose broadly obtuse point is directed out-
wards across the middle of the digital joint, and a little turned
upwards on the lower edge; within the curvature of this
apophysis is a strong, not very long, obtuse, prominent process
also directed outwards; and in front of it (though it was
difficult to see its exact origin) is a small, sharp-pointed,
spine-like projection ; numerous bristly hairs issue from the
outer side of the radial joint, chiefly towards its hinder part ;
the digital joint is oval and of tolerable size ; the palpal organs
are well developed and complex ; they are closely encircled
near the middle with a black spine; and a more slender one
coiled in a circular form is situated at their extremity.
The maville are of an olive-brown hue, the /abiwm blackish
brown ; the sternwm is glossy and black-brown; and the abdo-
men, which is also glossy, is jet-black, rather large, consider-
ably convex above, and very sparingly clothed with hairs.
This spider is closely allied to Walckenaéra pregracilis,
Cambr., but is larger ; the legs are also shorter; the eminence
on the caput is of a more rounded form, and less sloping
in profile both before and behind; the two eyes seated on its
summit are also nearer together. The palpi are somewhat
On new Species of Lepidoptera from Japan. 349
similar to those of that species; but the radial apophysis is
shorter, stouter, and more obtuse at its extremity, the process
also within its curvature is straighter, shorter, and stouter.
It is also allied to Walckenaéra erythropus, Westr., though
the palpi, as well as the eminence on the caput of this last
species, differ in structure, the digital joint being larger, the
radial apophysis less strong at its extremity, the process within
its curvature longer, more prominently turned upwards, and
furnished with a cusp-like point at its end.
A single example received for examination from Count
Keyserling, by whom it was found near Munich.

XLI.—Descriptions of new Species of Lepidoptera from
Japan. By Artuur G. Bur er, F.L.S., F.Z.8., &e.
THE moths described in the present paper were mostly pre-
sented to the British Museum by Mr. Henry Pryer of Yoko-
hama, who collected them in that locality. Amongst them
are many species of great interest, exhibiting marvellous re-
semblance to well-known European types, whilst one or two
show greater similarity to forms occurring in the New
World.
350 Mr. A. G. Butler on new Species of
One insect in Mr. Pryer’s collection I was much surprised
to find, upon examination, to be absolutely identical with a
West-Indian form; I allude to Gonitis fractifera. As the
Indian species of Gronitis seem to be constant to locality, the
various forms being nearly allied and limited in their range,
it is very strange to find a form common to St. Domingo and
Jamaica in Japan.
Sphingide.
1. Acosmeryx metanaga, n. sp. (no. 217).
dé. Rather larger than A. sericeus g ; coloration inter-
mediate between it and A. anceus ; markings of primaries and
entire coloration and marking of the under surface almost as
in A. naga—lilacine grey, clouded and banded with fuligi-
nous brown; wings tinted upon the disk with ferruginous ;
primaries with a lunated belt dividing off the basicostal area
and an oblique darker belt from the costa just beyond the
middle to the external border, both fuliginous brown; the
usual transverse undulated dark brown lines; outer border
smoky brown, undulated internally, intersected by a grey
stripe from the subcostal furca to the second median branch ;
a triangular subapical marginal dark-brown spot ; secondaries
greyish, becoming reddish on the disk, which is crossed from
near anal angle by a dusky bordered lilacine streak, followed
by a rather broad fuliginous outer border, which tapers to the
anal angle ; thorax, excepting the tegule, red-brown ; margins
of abdominal segments red-brown; antenne sordid white.
Expanse of wings 4 inches.
2. Pergesa mongoliana, var., Butl. (no. 219).
Differs from the ordinary Japanese examples in its much
deeper coloration above, the absence of the pale patches at
apex and on the disk of the primaries, and in the bright red-
dish coloration of the under surface. In this last character,
however, it agrees with the type from Mongolia.
3. Triptogon sperchius, Ménétr. (no. 205).
We have received a pair of what appears to be this species,
agreeing fairly with the published figures, and therefore
establishing the entire distinctness of my TZ. picetpennis.
Although | could not hesitate to describe an insect so entirely
distinct in coloration and marking as 7. picetpennis from the
figure published by Ménétriés, it is satisfactory to be able to
confirm the validity of the species by comparison with actual
specimens.
Lepidoptera from Japan. 351
Zygenide.
4. Illiberis sinensis, Walker (no. 243 B).
This insect has now come from Yokohama.
5. Procris funeralis, sp.n. (no. 244).
Deep purplish brown, the fringes paler; the disk of secon-
daries whitish and semihyaline ; abdomen black, claspers and
proboscis horn-yellow; a whitish extruded anal tuft. Ex-
panse of wings 9 lines.
Arctiidae.
6. Spilosoma leucothorax, Felder (no. 288).
This species is new to Japan.
7. Spilarctia imparilis, var., Butl. (no, 286).
The male now sent agrees with the typical female in
spotting, but the female sent with it agrees more nearly
with the typical male; it is therefore clear that, as in the
European species, the Japanese Spilarctie vary considerably
in the number of spots upon the wings.
8. Spilarctia inequalis, n. sp. (no. 294).
3. Wings above pale buff, becoming pink towards the
inner margins; a black spot at the superior angle of each
discoidal cell: primaries with a spot in the cell, two or three
close to inner margin, near to which commences an oblique
series from the centre of the margin to the lower discoidal
interspace, where it meets a series of abbreviated black dashes
running to the apex ; a second less distinct series of similar
dashes between the oblique series and the outer margin:
secondaries with a spot on the discoidal interspace and four
near the anal angle blackish grey: thorax white, the head
and shoulders tinted with buff; abdomen carmine, with lateral
black dots and fringe of ochreous hairs; antenne black.
Wings below nearly as above: body below whitish, the collar
and fringe of the palpi carmine ; upper surface of palpi and
of front legs and the tarsi and knees of the other legs black.
Expanse of wings 1 inch 4 lines.
2. Wings above semitransparent white, tinted with pale
buff at the borders; a blackish spot at the superior angle of
each discoidal cell: primaries with a double series of abbre-
viated black dashes as in the male, but without the oblique
series of spots or other spots noted as existing in that sex:
352 Mr. A. G. Butler on new Species of
secondaries with a spot near the apex and a second near the
anal angle: thorax and base of abdomen white ; remainder
of abdomen pink, but with the anal segments pale buif, a
series of black spots on each side; head slightly yellowish ;
antenne black. Wings below as above: body below white,
venter black-spotted, anus buff; collar and fringe of palpi
pink ; upper surface of palpi and of front legs black; upper
surface of the remaining legs brown. Expanse of wings
1 inch 10 lines.
The female at first sight looks almost like S. rhodophila,
whereas the male agrees better with S, obliqua.
9. Spilarctia rosacea, n. sp. (no. 289, ¢).
Primaries above fawn-colour, with the borders and veins
pale creamy buff; the basal third of costal margin black; a
small spot at the superior angle of the cell, a second on the
costa beyond it, a third just above the bend of the submedian
vein, an oblique series of black spots from inner margin to
apex, interrupted at the fourth median or lower radial branch;
an abbreviated series of black points near the outer margin :
secondaries rose-coloured, with the margins buff; a large
black spot at the end of the cell: thorax cream-coloured ;
head grey ; antenne and eyes black ; abdomen rose-coloured,
with dorsal and lateral series of black spots. Primaries below
bright rose-red, with the outer and inner margins and a patch
at basal third of costa ochraceous, base whitish, a black spot
at the end of the cell, a broad interno-median longitudinal
streak and an oblique series of spots from the latter to the
apex black: secondaries rose-coloured, with yellowish borders;
a black spot at the end of the cell: body whitish, palpi and
coxe and femora of anterior and middle legs carmine, tibize
and tarsi of hind legs blackish, venter laterally spotted with
black. Expanse of wings 1 inch 9 lines.
The insect sent as the female of this species is S. seriato-
punctata of Motschulsky, the male of which we previously
possessed ; the sexes of that species do not differ either in
size, form, or colour, whereas the insect now described differs
in all of these points, its chief resemblance, indeed, con-
sisting in the presence of the black basicostal streak on the
primaries.
Lithosiide.
10. Cyana decipiens, n. sp. (no. 1126).
Primaries sordid white, with broad chocolate costal border
not quite reaching the base, a dusky-bordered, irregular, sub-
Lepidoptera from Japan. 303
basal, pale sandy yellowish stripe, and a second across the
disk, close to the external border ; the veins upon the broad
central area enclosed by these two stripes dotted with oliva-
ceous ; external area limited internally by a series of black
>-shaped markings, almost forming a zigzag line; external
angle clouded with olivaceous; fringe obliquely streaked with
ferruginous ; an oblique curved discocellular black dash ;
costal margin yellowish, spotted with olivaceous : secondaries
shining white, with slightly brownish external area, broadest
at apex: body white. Under surface sordid white, primaries
broadly suffused with grey ; a discal series of blackish semi-
circles near the outer margin; fringe as above. HExpanse of
wings 1 inch 7 lines.
This species wonderfully resembles the New-Zealand genus
Declana.
11. Miltochrista torrens, n. sp. (no. 266).
Primaries bright orange, with costal and outer margins red;
two black dots at the base ; two blackish irregular lines upon
the basal half from inner margin to subcostal vem: secon-
daries yellowish rose-coloured, with bright rosy border; fringe
of all the wings ochreous: thorax reddish orange; abdomen
buff, with dorsal and lateral series of black dots. Under
surface pale rosy, with the borders of the wings brighter in
colour ; body yellowish. LExpanse of wings 1 inch.
12. Systropha nivosa, n. sp. (no. 270).
Snow-white, wings sericeous; primaries below pale brown
with white fringe; anterior and middle pairs of legs brownish
above. Expanse of wings 1 inch.
Notodontide.
13. Stauropus persimilis, n. sp. (no. 321).
Closely allied to S. fag?, but smaller, the ground-colour of
the wings more uniformly reddish brown, the basal pale area
of primaries much less defined; the whitish border below
obsolete. Expanse of wings 2 inches 2 lines.
This is, of course, nothing but a small representative race
of S. fagi; the caterpillar, probably of this species, from
Hiogo, is black with castaneous head.
14. Peridea cinerea, n. sp. (no. 331).
Nearly allied to P. sikkima, with the same markings, but
much smaller, altogether greyer, and with the yellow spots
304 Mr. A. G. Butler on new Species of
on the disk of primaries replaced by snow-white ones; the
primaries and thorax, seen as a whole, are distinctly ash-
coloured instead of greenish brown. Expanse of wings
2 inches.
This species is of the same general tint as Phalera sigmata ;
but the body is browner; it and “ Heterocampa” stkkima are
decidedly best placed in Peridea, with which they appear to
agree in all essential points of structure.
PALECA, n. gen.
Allied to Cleapa, but with the palpi nearly twice as large
(giving the genus quite a Deltocd character), and with the
antenne less widely pectinated, with the apical fourth simple ;
body slightly more slender and decidedly longer. Type P.
rufescens.
15. Paleca rufescens, n. sp. (no. 1067).
Primaries above clay-coloured, shining; the basal and
external thirds dusky and edged with a pale line, so that the
central third forms a broad belt, expanding upon the costa,
and enclosing a blackish discocellular spot: secondaries pale
shining brown, the external half being distinctly more dusky
with defined inner edge: thorax clay-coloured, abdomen pale
brown. Under surface pale cupreous brown, shining ; wings
with indications of a blackish discal line and with black
discocellular spots. xpanse of wings 1 inch 3 lines.
INGURIDIA, n. gen.
Allied to Ingura (I. recurrens), but the wings broader, the
secondaries altogether larger; antennez: simple, palpi slightly
more slender ; hind legs quite as strongly quadrispinose, but
apparently rather less densely hairy ; pectus covered with
long coarse hairs. ‘Type J. abrostolina.
16. Inguridia abrostolina, n. sp. (no. 782).
Dark brown, primaries above clouded with greyish; the
discoidal spots and a large rounded spot below the cell indi-
cated by black outlines, and enclosed by two transverse black
lines, which indicate the central belt; a pale grey submar-
ginal line and a black marginal line formed of confluent
lunated spots; head and thorax pale and silvery, abdomen
dark greyish brown. Under surface dark brown, shining ;
wings with a darker discal line and pale fringe; the fringe of
Phe ene almost wholly white. LExpanse of wings 1 inch
1 line.
Lepidoptera from Japan. 355
This species, though similar in general tint to the allied
genus Ingura, is even more like Abdrostola in pattern and
coloration.
17. Lophopteryx Pryert, n. sp.
Near to the ‘‘ Notodonta”’ Sieversti of Ménétriés, but shorter
in the wings, with more prominent scale-tooth from the inner
margin of the primaries, and with the central belt and discal
spots on these wings more sharply defined. Expanse of
wings 1 inch 5 lines.
L,. Sieversii is carefully figured ; and therefore, although we
do not possess the species, I have no difficulty in charac-
terizing the Japanese insect as distinct.
Drepanulide.
18. Oreta auripes, n. sp. (no. 348).
?. Allied to O. calida (Ill. Lep. Het. pl. xxii. fig. 6), size
of the male of that species, and of the same general colour
above—laky brown, mottled with grey; wings crossed by
two grey lines, wider apart than in O. calida, the outer one
on primaries incurved and bounded by an ill-defined yellow
line which runs to apex; fringe and margin of secondaries
bright ferruginous: body pale whity brown, the metathorax
and abdomen slightly rosy; head and antennz ochreous ;
collar rosy brown. Wings below bright ochraceous, clouded
with rosy reddish, reticulated and dotted with lilacine grey ;
a curved discal line of the same colour across the primaries :
body below creamy yellowish ; anterior legs bright reddish
orange; other legs golden orange. Hxpanse of wings 1 inch
9 lines.
This species should be placed between O. calida and O.
pulchripes. Drepanulides palleolus, Motschulsky (no. 345),
is a Callidrepana.
Saturniide.
19. Tropwa aliena, u. sp. (no. 323).
6. Wings above pale yellowish green *, white at the base
and along the abdominal border of secondaries; the usual
small oval ocelli closing the discoidal cells; a slightly sinuous
yellowish olivaceous discal stripe from costa of primaries to
abdominal margin of secondaries ; fringe pale sandy yellow:
primaries with a second, irregular, oblique, subbasal, yellowish

traces of this colour on the underside of the wings.
356 Mr. A. G. Butler on new Species of
olivaceous stripe; costal border sordid plum-colour, densely
irrorated in front with white scales, and bounded behind by
a black stripe: body white; the head, collar, margins of
the thorax and abdomen slightly yellowish ; a broad belt of
dark plum-colour across the prothorax and tegule ; antenne
bright testaceous; hind margin of eyes red. Wings below
with an undulated discal line in place of the sinuous stripe of
the upper surface; body below sordid white, palpi and legs
rosy. Expanse of wings 5 inches 10 lines.
This beautiful species most nearly agrees with the Mexican
T. dictynna, but differs in the absence of the conical chocolate
patch uniting the ocellus of primaries to the costal border, in
the more wavy discal stripe, and the presence of a second
stripe towards the base of the primaries.
Linneus evidently confounded 7. dictynna with T. luna;
for although, in the 10th edition of his ‘Systema,’ he quoted
Catesby’s figure of the North-American insect and Petiver’s
representation of the same species as illustrations to his brief
diagnosis, yet for the fuller description given in the ‘ Museum
of Ulrica’ he quoted Clerck’s ‘Icones’ first of all; and the
figure in the latter certainly represents the Mexican species,
inasmuch as the wings are crossed by a well-defined discal
stripe. It is probable that both descriptions are taken from
the northern type.

that it is only a slightly rubbed example; all the markings
are the same.
27. Leucania extranea, var., Guén. (no. 647).

sight I was inclined to believe a distinct species; I have,
however, found a specimen similarly coloured in the collection

The above description is taken from specimens obtained by
Mr. Jonas. I delayed describing the species as I not only
felt doubtful as to its correct location, but was uncertain as to
the constancy of the characters distinguishing it from T.
fenestrella of Europe. I now feel satisfied that it is distinct,
having seen additional examples; and I have little doubt that
its natural position is amongst the Noctuites, in the neigh-
bourhood of Penicillaria.

XLIL.—On the Nutritive and Reproductive Processes of
Sponges. By H. J. Carrer, F.R.S. &c.*
CoNFLICTING statements have been made respecting the
nourishment of sponges, which need but a little explanation to
become reconcilable.
The subject has only just now presented itself separately,
because it has hitherto been implied rather than stated that
the nourishment of sponges was derived from foreign bodies
observed in their interior.

Reproductive Processes of Sponges. 375
Still, while attempting this reconciliation, it is necessary to
bear in mind that the sponge-cell is unceasingly polymorphic
except under the resting-form, which is spherical, and that this
polymorphism enables it to assume a monadic monociliated
form at one time and immediately afterwards almost any
unciliated amoeboid one that can be conceived—apparently
amalgamating with its neighbours into a homogeneous mass,
yet at any moment ready to separate and resume any of its
wonted forms under favourable circumstances.
In 1849 I noticed that the “sponge-cell ¢ése/f frequently
contained pieces of Conferve within duplicatures of its cell-
wall, and other matters”’ similar to what might be seen in
the “ proteus” = Ameba (no. 3, p. 94); also that the “ living
sponge’ presents ‘ejecta”’ on its surface, which “ consist

376 Mr. H. J. Carter on the Nutritive and
of the cast-off parts of organisms from which the nutrient
parts have been abstracted (2. p. 98).
In 1857 (while still at Bombay, and totally ignorant of
what Lieberkiihn subsequently published at Berlin in the
month of June of that year, from his communications to the
“Gesellschaft naturforschender Freunde,’ on the 6th Sept.
and 2nd Dec. 1856) I stated, among numerous other obser-
vations on the development of Spongilla from the seed-like
body, that, on watching the feeding of it with carmine
under the microscope (with immersed object-glass, of course),
the particles may be seen to pass into the ampullaceous
sacs (“ Wimperkérbe”), where they are “instantly en-
closed by the sponge-cell (spongozoon) on which they
inpinge”’ (no. 6, p. 28); that the colouring-matter then is
“wholly confined” to the ampullaceous sacs, and that
when the latter are torn to pieces it is found to be con-
tained in their cells (spongozoa), some of which are mono-
and others unciliated; further, that after a little time the
circulatory system of the young Spongilla becomes sus-
pended synchronously with the closure of its now single
osculum and the retraction of the tubular process which
supports it; this lasts for about a ‘quarter of an hour,”
when the circulation is resumed the proboscidian process
reproduced, the osculum at its extremity reopened, and
that portion of the particles of carmine which may be as-
sumed to have been deprived of their nutritive parts may
be seen to leave the ampullaceous sacs, one after another,
and, passing along the canals of the excretory system, finally
to rush out at the osculum (no. 6)*. Here, then, it was
naturally implied, rather than stated, that this was at least
one of the ways in which nourishment got into the sponge.
It is also desirable to note that, among the carmine-
bearing cells torn out from the ampullaceous sacs, there
were unciliated as well as monociliated cells, and to con-
nect this with the fact that shortly after a monociliated
sponge-cell is eliminated from the sponge it loses its active,
living, monadic form, and, retracting its cilium (which is but
a hair-like extension of its own polymorphic body), assumes
the more passive, amoeboid one, which is really the only visi-
ble characteristic distinction between the monociliated cell of
the ampullaceous sac and the cell of the parenchyma. Hence,
whether the foreign material be in one or the other, the nutri-
tive process may be assumed to be the same in both.
In 1857, also, Lieberkiihn stated that on feeding Spon-
* This paper, in importance and amount of fact, is, to me, the best I
have ever published on sponges.
Reproductive Processes of Sponges. 377
gilla with carmine the particles entering by the pores were
conveyed to and stuck in (‘‘stecken”’) the ampullaceous
sacs (“ Wimperorgane’’) (no. 7, p. 384); also that Infu-
soria passing through the “ canal-system ’’ were taken into
the parenchyma (‘ Kérperparenchym”), and there falling
to pieces, after some time disappeared without leaving a
trace behind, after the manner of an infusorium which had
been devoured by an Actinophrys (cb. p. 388).
Although nothing is said here, again, about “ nourish-
ment,’ no one can doubt what was passing in Lieberktihn’s
Sagacious mind at the time, viz. that the Infusoria thus
afforded nutrient matter to the Spongilla.
We now cometo Hickel’s views in 1872, viz. that the flagel-
late cells of the endoderm (‘‘ Geisselzellen des Endoderms’”’)
are exclusively the organs of reception for the digestion of the
food (no. 11, vol. i. p. 372); and these we may pass by with
Metschnikoff’s observation, viz. that they are theoretical and
not founded on matter of fact (no. 20, p. 372). This brings
us to the following statements of Metschnikoff himself in
1879, made under the heading “ Ueber die Nahrungsaufnahme
bei Spongien”’ (no. 20, p. 371).
Beginning with Lieberkiihn’s observations, Metschnikoff
observes that they were made more than twenty years ago,
and that their result has of late been “ lost sight of.” If it
had not been for Lieberkiihn’s observations, my own, which
were made seven years previously, would have shared the
same fate (no. 5, p. 400).
With Metschnikoff undue prominence seems to be given
to the cells of the parenchyma (mesoderm) in the nourish-
ment of the sponge. It is true that he says the ampullaceous
sacs (“ Wimperkérbe’’) were ‘ usually’? empty, and that in
some sponges nourishment is carried on by the mesodermal
element. But why, with the facts above stated, should he
give illustrations (no. 20, Taf. xxii. figs. 16, 17) wherein the
mesodermal cells are represented as charged with particles of
carmine and the ampullaceous sacs (“ Wimperkérbe ’’) empty,
without in the text alluding to the opposite results of other
experimenters, and conclude his observations with the state-
ment that it was clear that the mesodermal cells could take
in the material and were more or less able to digest it (no. 20,
p- 374) ?—which implies that they alone are the nutrient
organs, as the ampullaceous sac (“‘ Wimperkorb”’) is not men-
tioned.
It is possible, and I should think probable, that Metsch-
nikoff has never seen my paper ‘‘ On the Ultimate Structure
of Spongilla”’ (no. 6), and therefore is not aware of the
Ann. & Mag. N. Hist. Ser. 5. Vol. iv. 27
378 Mr. H. J. Carter on the Nutritive and
reflection which his observations cast on the statement that,
in my experiments, the carmine or “ colouring-matter was
wholly confined to the ampullaceous sacs.” But then he
ought to have been acquainted with that of Lieberkiihn to
which I have alluded, and which is in the page preceding that
to which he has called attention (no. 20, p. 3871, footnote), and
again in 1857, viz. ‘in Wasser befindliche Karminkérnchen
sieht man hier aus dem grossen Hohlraum unmittelbar in
jene Wimperapparate gelangen” (no. 7, p. 385). That I
should have made the statement in 1857 that the carmine was
“wholly confined to the ampullaceous sacs” is no excuse for
an observer in 1879 exclusively mentioning the cells of the
parenchyma as engaged in this process.
Besides, in feeding the calcareous sponges with carmine
and indigo respectively, the colouring-matter has always
appeared to me to be so confined to the sponge-cells (spongo-
zoa) of the ampullaceous sacs, that I have not sought for it
anywhere else ; while I have sometimes seen the green germ
of an Alga, together with the colour-particles, in the body of
a spongozoon.
Nevertheless our thanks are due to Metschnikoff for having
especially pointed out that the mesodermal cells are capable
of taking in nutritive material and digesting it, because, toge-
ther with what had gone before, it is now shown that whether
ciliated and in the ampullaceous sac, or unciliated and in the
parenchyma, the sponge-cell generally is at least an alimen-
tary organ; and thus the “ conflicting statements” to which
I have alluded become reconcilable.
Should the reader be inclined to recur to my paper in the
‘Annals’ of 1849, he will there find the following para-
raphs :—
“ Tf a seed-like body which has arrived at maturity be placed
in water, a white substance will, after a few days, be observed
to have issued from its interior, through the infundibular
depression on its surface, and to have glued it to the glass ;
and if this be examined with the microscope, its circumference
will be found to consist of a semitransparent substance, the
extreme edge of which is irregularly notched or extended
into digital or tentacular prolongations, precisely similar to
those of the protean [Ameba], which, in progression or in
polymorphism, throws out parts of its cell in this way (pl. iv.
fig. 2,c). In the semitransparent substance may be observed
hyaline vesicles of different sizes, contracting and dilating
themselves as in the protean (fig. 2, d), and a little within it
the green granules so grouped together (fig. 2, e) as almost
to enable the practised eye to distinguish ¢n situ the passing
Reproductive Processes of Sponges. 379
forms of the cells to which they belong; we may also sce in
the latter their hyaline vesicles with their contained molecules
in great commotion, and between the cells themselves the
intercellular mucilage (fig. 2, f).
“If this newly formed sponge be torn up, its isolated cells
assume their globular or passive form, or become polymor-
phous, changing their position and their locality, by emitting
expansions similar to the proteans or polymorphic cells deve-
loped after a forcible expulsion of the contents of the seed-
like body, and differing only from them in being more
indolent in their movements ” (no. 3, p. 91, pl. iv. fig. 2).
With this statement, at that comparatively early period,
how was it possible to come to any other conclusion than that
every part of the sponge-parenchyma is capable of enclosing
nutritious material and digesting it like the Ameba (‘ pro-
tean’’), even if we had not had the observations of Lieber-
kiihn, confirmed by Metschnikoff (no. 20, p. 374), to establish
the fact ?
In the first paragraph above quoted I have mentioned the
extreme edge of the young Spongilla as composed of semi-
transparent substance charged with hyaline vesicles, as if this
were a distinct portion; but from what I have stated at the
commencement of this paper respecting the homogeneity of
ameeboid cells after amalgamation, defying all attempt to de-
tect their individuality, although capable at a moment’s notice
of separating themselves from each other (as in the conjugation
of two Difflugie), it is quite possible that this “‘ semitrans-
parent substance’? may be composed of sponge-cells thus
combined, and the ‘ hyaline” their ‘‘ contracting’’ vesicles
respectively, since, as I have heretofore shown, the ap-
parently homogeneous investing membrane or cuticle of the
young Spongilla is so composed (no. 6, pp. 24, 25, pl. 1.
fig. 7).
Slabs with this is the curtous fact that the whole of the
spongozva of an ampullaceous sac (“‘ Wimperkorb”’) may, under
isolation, become thus amalgamated, and assume the form and
habits of an Amaba, while the cilia of the spongozoa may be
seen still playing in its interior, and the exterior enclosing
particles of carmine which come into contact with it (no. 6,
p- 26)—finally losing all appearance of cilia internally, and
presenting an actinophorous form (db. p. 33, pl. 1. fig. 9).
Since, then, we find Balfour (no. 19, p. 108) stating, “ It
has not, so far as I know, been definitely made out where the
digestion is carried on. Lieberkiihn would appear to hold
the view that the amceboid lining-cells of the passages are
mainly concerned with digestion, while Carter holds that
27*
380 Mr. H. J. Carter on the Nutritive and
digestion is carried on by the collared cells of the ciliated
chambers,” the above must be my reply.
Although at one time the foreign material may be chiefly
taken in by the sponge-cells (spongozoa) of the ampullaceous
sac, and at another by the sponge-cells of the parenchyma, it
cannot be inferred that there are two systems of alimentation,
but rather that they are both the same, only that they are
respectively more or less used according to circumstances.
Again, while it may be generally thought that there is no
direct communication between the inhalant orifices (pores) of
the surface and the exhalant or excretory canal-system of the
interior except through the ampullaceous sacs (‘‘ Wimper-
kérbe’’), facts now prove that branches of the excretory canal-
system may commence directly under the pores (no. 10, pl. vil.
fig. 5, and no. 21, pl. xxv. fig. 4, e, &c.); so that whatever
nutritious material may be in the water which thus passes
directly into the excretory canal, must be deflected from it to
arrive where the sponge-cells of the ampullaceous sac and
parenchyma respectively are naked—that is, uncovered by any
membrane which would prevent the particles of food from
coming into direct contact with them—indeed, where the
canals are formed by the sponge-cells alone, as stated by
Lieberkiihn (no. 7, p. 388).
Bearing upon Nutrition is Starvation, under which, as I
have long since stated (no. 2, p. 309, and no. 6, pp. 82, 33),
the sponge-cells leave their “ habitation” (that is, the skeleton)
and creep about the watchgiass wherein the young Spongilla
might have been allowed to grow out from the seed-like body.
Lieberkiihn has recorded that the cells of Spongilla in the
river Spree at Berlin are ameeboid in the winter, but put
forth a cilium in spring (no. 5, p. 2); and this is confirmed
by Metschnikoff in Spongilla from the Dnieper in the months
ot October and November, together with the well-known fact
that under ‘‘ unfavourable” circumstances the retraction of
the cilium may take place at any time (no. 20, p. 575).
But that the putting forth of the cilium in spring and its
retraction in winter, when, as Metschnikoff states, the Spon-
gilla had become charged with gemmules (seed-like bodies),
seems to show that the active life of this sponge takes place
during the warmer part of the year, like that of most orga-
nisms, when nourishment is chiefly required for the fulfilment
of the reproductive process ; and that the passive or amceboid
state of the cells not only took place in the winter, when this
activity was not required, but that the cilium at all times
would be retracted under ‘ unfavourable circumstances,” ac-
cording to Metschnikoff (no. 20, p. 375), may be inferred
Reproductive Processes of Sponges. 381
from the simple fact that these unfavourable circumstances
take place before one’s eyes when the Spongilla or any other
sponge is torn to pieces; while Metschnikoff states that, on
the other hand, when the favourable circumstances were
renewed (“‘ erneuertem Wasserwechsel ’’), not only the cilium
but the ampullaceous sac (“ Wimperkorb ”’) was remade in the
parenchyma of a young Spongilla.
I cannot say, however, that the sponge-cells of Spongilla
lose the cilium in the winter in the tanks of the island of
Bombay, perhaps because the temperature then and there is
about that of our midsummer, since the last mention of it in
my ‘ Note-book,’ together with an illustration in which the
“ ear-like processes ”’ (collar) are represented, is dated “ 9th
January, 1859,” just after my paper on the subject had been
published in England (no. 8, p. 14, pl. 1. figs. 12-14).
Reproductive Process.
While on the subject of alimentation, it might be as well
to briefly enumerate the facts known in connexion with repro-
duction, since the latter is chiefly dependent on the former
process.
As early as 1826, my late kind and talented teacher Prof.
Robert Grant described and illustrated (among his imperish-
able records of the Spongida) the embryo (swarm-spore) of his
Spongia panicea=Halichondria incrustans, Johnston, begin-
ning with the ovum “ lying in the recesses of the parenchy-
matous matter,” following its development into the ciliated
embryo, its exit afterwards through the excretory cell-system
and subsequent fixation, finally ending in the full develop-
ment of the young sponge (no. 1, pp. 127-133, and p. 140,
pl. u. figs. 26-29).
In 1854 I described and figured minute monociliated bodies
which were observed in Spongilla at Bombay in the month
ot July, and conjectured to be zoosperms (no. 4). Afterwards
Lieberkiihn described and figured undoubted spermatozoa in
Spongilla in July, at Berlin (no. 5, pp. 17, 18, pl. xv. fig. 34,
and pl. xviii. figs. 10-17), previously observed by Miiller
(no. 5, p. 19).
That Lieberkiihn should have identified my description and
illustrations with Trachelius trichophorus, Ehr., I could never
understand, because he must have known that the former
carried the cilium behind, and Trachelius carries its cillum in
front. Moreover, although I have hitherto been inclined to
doubt if they really were spermatozoids or the common mono-
ciliated sponge-cell, I now observe, by the measurements
of both (which have fortunately been published with their
382 Mr. H. J. Carter on the Nutritive and
descriptions respectively), together with my better acquain-
tance with the subject, that the smallness ot the monociliated
bodies which I figured as zoosperms, when compared with the
“eared”? (collared) monociliated sponge-cell, 1s so much in
favour of what I had conjectured, that little doubt can be
entertained by those familiar with such bodies that they
really were the zoosperms of Spongilla. The time of their
appearance in the Spongilla, their mode of progression, and
their inferior size, it we do not admit the absence of the ear-
like processes (collar) also, must satisfy the most fastidious
mind that they could have been nothing more or less than
“¢ zoosperms.”’
About the same time also, viz. 1856, Lieberkiihn dis-
covered and described, with illustrations, the swarm-spore
(embryo) of Spongilla and its development, which Grant, as
above stated, did of Halichondria incrustans in 1826 (no. 5,
pp: 9-14 and pp. 405-413, pl. xv. fig. 35).
Finally, F. E. Schulze, in 1877, pointed out the existence
of spermatozoa in Halisarca lobularis in a much more satis-
factory way than had hitherto been done, as testified by his
descriptions and illustrations (no. 17, p. 24, Taf. ii.), toge-
ther with some of his beautiful preparations, which, through
his great kindness, are now in my possession.
They occur in the form of globular groups (‘Sperma-
ballen”’), so like in size and appearance to the ampullaceous
sacs (‘‘ Wimperkérbe’’) that, but for the smallness of the
monociliated colourless head of the former, they would be
almost undistinguishable from the larger monociliated and
collared form of the latter, both being polymorphic and bearing
the proportion of about 1 to 5 (compare Schulze’s fig. 12, Taf.
li., with fig. 17, Taf. iii., both of which are magnified 800
times). In size the two look respectively very much like the
so-called microspores and macrospores of Algz; and at first
one would be inclined to think that reproduction was similarly
accomplished by their union. But another factor steps in here,
viz. the unciliated sponge-cells of the parenchyma or meso-
derm, which Metschnikoff has shown to take in nourishment
equally with the monociliated cells of the ampullaceous sacs,
or, at all events, to do so when the latter do not. And here
(in the mesoderm) it is, that the ova appear (see Schulze’s
satisfactory figure of the eggs in Sycandra raphanus, H.,
no. 14, Taf. xvii. fig. 2)—a tact that all who have studied
any of the calcareous sponges in spring (that is, during the
reproductive period) must be well aware of, although Grant,
who first mentioned this, observed it (Halichondria incrus-
tans) during the autumn (‘‘ October and November ”) (no. 1,
Reproductive Processes of Sponges. 383
p. 128). Then the time varies with the species, as Grant
has observed (no. 1, p. 133).
The spermatozoa which I saw in 1854 bore the proportion
of about 1 to 5 when compared with the average size of the
common sponge-cell in Spongzlla, as the latter is much the
largest. Those which Lieberkiihn figured in 1856 bear a
similar ratio; and so do those figured by Schulze in Hali-
sarca lobularis.
The smallest size at which I could recognize the egg in
Halisarca lobularis was 1-3000th inch (no. 13, p. 31, pl. xx.
fig. 3, a); while the monociliated sponge-cell of the ampulla-
ceous sac was a little smaller, viz. about 1-3600th inch in dia-
meter (7b. fig. 2, a) ; and Schulze’s figures of the body of a
monociliated collar-cell (“‘ Kragenzell”’), compared with that of
the spermatozoid (no. 17, 7. c.), give about 1-18000th of an
inch for the latter. It might be thought that it would have
been better to have been able to omit the indefinite word
“about”? (c?vea) ; but those who have s‘udied the minute ana-
tomy of sponges well know that all their soft parts afford,
from polymorphism and actual difference in size, only ap-
proximate measurement.
Hickel is the only one who believes (“‘ glaube”’) that he has
seen the spermatozoids enter the ovum (no. 11, vol. i. p. 396,
Atlas, Tat. 48. fig. 6) in Sycortis lingua=Grantia ciliata,
Bowerbank.
Keller of Zurich also gives a figure of it in Leucandra
aspera, H., with reasons for coming to the conclusion (no. 16,
p- 21, Taf. 1. fig. 4, c).
But of all those who have so deeply studied the living
calcareous sponges, it has been reserved for Hickel alone to
see the act; and this, according to his statement (no. 11, vol. 1.
p- 396), he has done repeatedly (‘‘ wiederholten Malen’’). Yet
if his statements and figure are like those which he has given
of my Sguamulina scopula (‘ Jenaische Zeitschrift f. Natur-
wissen.’ Bd. ix. 1877), I regret to be obliged to say that they
are not trustworthy, as may be seen by Saville Kent’s ample
confirmation of my observations of 1870 in 1578 (Ann.
vol. ii. p. 68, pls. iv. & v.) ; while it was not difficult to con-
jecture, with apparent certainty, that which the sagacious
Lieberkiihn had indicated sixteen years before by his descrip-
tions and figures of the swarm-spore and spermatozoa respec-
tively in Spongilia (I. c.).
Another difficulty here presents itself, viz. that, from the
polymorphic condition of all the soft parts in the living
sponge, even to the capsule of the ovum, it becomes doubtful,
unless the spermatozoon is seen to enter the ovum, whether
384 Mr. H. J. Carter on the Nutritive and
the remaining projection of the still waving tail, such as those
in Keller’s instance, is confirmative of impregnation, simply
because, when these polymorphic bodies become amalgamated,
their water-like sarcode so flows together that their individu-
ality becomes lost—although, where the body is not a sperma-
tozoon, they can immediately individualize themselves again.
Nothing is more like the ‘“ melting away” of a_spermato-
zoon when it passes into the ovum than the union of two
polymorphic amoeboid Infusoria; so, unless the act itself is
seen (that is, the spermatozoid and ovum are both observed
before union), the case may only remain “ probable,” as
Keller has observed.
Gemmule or Seed-like Body of Spongilla.
Turning our attention shortly to the seed-like body of
Spongilla for our present purpose, as I have already given this
in detail (no. 12), we find that it is more or less globular in
form according 1o the species, variable in size, although
generally nearly as large as a small pin-head, so that they can
be easily seen by the unassisted eye, congregated towards
the base or first-formed parts of the Spong7lla, consisting of
a cellular crust more or less charged with peculiar spicules,
lined by a coriaceous membrane, and filled with a yellowish
substance, something like the yelk of a hard-boiled egg,
which is composed of transparent spherical sacs varying
under 1-1000th inch in diameter, more or less filled with
grain-like transparent compressed firm cells of different
sizes varying under 1-3000th inch in diameter, bearing in
one part of the crust a hilous aperture, through which the
contents issue a few days after the seed-like body has been
placed in water, in the form of the young Spongilla (no. 3,
p- 87, pl. ui. fig. 6, a-z).
If this growth be made to take place in a watchglass under
cover of a bell-glass, or something of the kind, replenishing
the water as required, it can easily be transferred to the field
of a microscope from time to time, where it can be viewed
under 3-inch object-glass, of course immersed; when the
“transparent spherical sacs” with their ‘ grain-like cells”
appear to issue entire with the rest of the substance from the
seed-like body, and so become developed in their entirety,
respectively, in this substance, now assuming the form of a
parenchyma (no. 6, pp. 21, 22).
On the other hand, the development of the swarm-spore or
embryo leads to the same result, when some of its cell-contents
-also become developed into ampullaceous sacs (no. 13, p. 337,
pl. xxi. fig. 21, c, &e., and pl. xxii. fig. 34, d).
Reproductive Processes of Sponges. 385
In the future development of Spongilla the ‘“ transparent
spherical sac” and its contents, which have become developed
into an ampullaceous sac (‘‘ Wimperkorb’’), appear to me to
grow into a gemmule or seed-like body (no. 6, p. 34), and
thus this increase or reproductive process to be successively
effected.
That the “ grain-like cells” of the transparent sacs do
pass into monociliated sponge-cells may be proved by taking
out some of the “ yellow substance” on the point of a needle
and placing it in a watchglass with distilled water, when,
after a few days, the “ grain-like cells” for the most part
disappear and are followed by a development of active mono-
ciliated sponge-cells (no. 3, p. 91, and no. 12, pp. 97, 98).
Now comes the question whether the monociliated “sponge-
cells” of the ampullaceous sacs (“ Wimperkérbe’’) are impreg-
nated by the spermatozoa for the formation of the seed-like
body, and the cells of the parenchyma or mesoderm for the
formation of the ovum respectively.
When we reflect on the almost identity that exists between
the spongozoon or monociliated sponge-cell and the solitary
flagellated infusorium called ‘ Salpingeca”’ by the late H.
James-Clark, who first pointed out the resemblance (no. 9),
we can hardly help thinking that what the “ solitary’ form
possesses in the way of organs is equally possessed by the
social one or monociliated sponge-cell, and we can hardly doubt
that the solitary Salpingeca and its like possess either an
hermaphroditic, moncecious, or dicecious system of reproduc-
tion respectively ; while, assuming that of the sponges to be
moneecious, the female organ or ovary must be looked for
either in the monociliated sponge-cells of the ampullaceous
sac (“ Wimperkorb’’), or in the unciliated sponge-cells of the
parenchyma or mesoderm ; and if this be the case, then we
must consider the ampullaceous sacs in the marine sponges
(wherein there are no seed-like bodies) abortive in this
respect, and the ovum to be developed from the nutritive
sponge-cells of the parenchyma. And as there are swarm-
spores as well as seed-like bodies in Spongilla, both may
become impregnated and developed in their respective cells,
as already intimated, for the purpose of reproduction, in which
case impregnation would take place in the body of the sponge-
cell. How happens it, then, that Hickel has seen impreg-
nation of the ovum to take place in the parenchyma or meso-
derm? Perhaps the ova may be thrown off from the ovary
of the parenchyma-sponge-cell in a very minute form, dis-
charged, and then transported into the intercellular substance
for increased growth previous to impregnation.
386 Mr. J. Wood-Mason on a new Genus
What Dr. Grant said of the sponge fifty-three years ago
(no. 1, p. 138), equally applies to it at the present day, viz.:—
‘This animal still affords many curious and interesting sub-
jects of inquiry to those who have leisure and opportunities
of examining the more perfect species of tropical seas [? in
temperate ones too!]; and, though probably the simplest of
animal organizations, the investigation of its living habits, its
structure and vital phenomena, and the distinguishing cha-
racter of its innumerable polymorphous species, is peculiarly
calculated to illuminate the most obscure part of zoology, to
exercise and invigorate our intellectual and physical powers,
and to gratify the mind with the discovery of new scenes of
infinite wisdom in the economy of Nature.”
XLITI.—Preliminary Notice of a new Genus (Parectatosoma)
of Phasmidex from Madagascar, with brief Descriptions of
ats two Species. By J. Woop-Mason*.
THE interesting and remarkable animals briefly noticed below
formed part of a large collection of insects, chiefly Coleoptera,
recently received in London from Madagascar; and | was
fortunate, while at home on furlough, to secure specimens of
them from Mr. E. W. Janson, the well-known Natural-His-
tory agent.
They are unquestionably nearly related to Hctatosoma, an
Australian genus, the three known members of which are
three of the most curious and striking forms comprised in the
whole class Insecta. This relationship I have indicated in
the name of the new genus which the differences presented
by these insects compel me to propose for their reception.
PARECTATOSOMA J, gen. nov.
Closely allied to the Australian genus LEectatosoma, but
differing therefrom in the following characters :—The pro-
thorax is relatively longer and more spiny; the male is
devoid of ocelli, and, like the female, brachypterous; the
abbreviated tegmina in both sexes are shorter than the abbre-
viated wings ; and the upper crest of each of the femora is
produced into a sharp genual spine.

nules) arranged in four longitudinal rows and in pairs, of
which one is large, compressed, and thorny, and constitutes
the conspicuous cephalic horns; the pair of spines imme-
diately in front of these is also compound, each being pro-
vided with a sharp spine-like cusp in front. The post-
antennary pair of spines is as well developed as in Ketato-
soma.
Sides and upper surface of prothorax strongly armed with
thorns, some of which are double. The apices of the small
tegmina barely reaching the bases of the wings; the true
metanotum is consequently exposed, and it is armed at the
middle of its hinder margin with a pair of stout thorns. The
tergum of the first somite and the terga of more or fewer

cesses.
Colour deep black-brown, almost black, blotched with
yellow, sparingly so on the under surface and legs, but more
profusely on the pronotum and on the terga of the abdominal
somites, on which parts the colour assumes an orange tinge
and extends to the points of the spines; the antenne are
ringed at the joints with the same colour; organs of flight
greenish yellow, with their bases and principal nervures black.

spines, besides spinules, the cephalic horns more foliaceous
and more sharply spined, with only one pair of spines in front
of them instead of two, and that simple; male with eight
only, one of the lateral pairs not being developed. Post-
antennary spines reduced to minute tubercles. Vestiges of
wings and tegmina larger, those of the latter overlapping one
another and those of the former so as to conceal from view
all but about one square millimetre of the unarmed meta-

XLIV.—Monobia confluens, a new Moneron.
: 5]
By Aime ScHNEIDER*,
[Plate XVIII. ]
I now present the description of a new Moneron, which ap-
pears to me to possess some interest. The name I give it is
in allusion to the community of life which is set up between
the different individuals of the same group, the different mem-
bers of a colony, as will be seen by-and-by.
Monobia confluens lives in fresh water, and perhaps also in
moist earth. I met with it for the first time in June 1878.
T have had living representatives of it for about a week in a
* Translated by W. 8. Dallas, F.L.S., from the ‘ Archives de Zoologie
expérimentale,’ tom. vil. (1878) p. 585.
M. A. Schneider on a new Moneron. 389
moist cell under my microscope ; and they have furnished me
with the following observations.
In its simplest form in a state of repose Monobia confluens
is a small nearly spherical mass of finely granular sarcode,
appearing bluish by transmitted light, without a nucleus and
without a vacuole (Pl. XVIII. fig. 1) From this homoge-
neous body radiate in all directions excessively delicate pseudo-
podia, so long that they are four times the length of the
body, so slender and transparent that one can hardly trace
them except by the aid of the small inflations, like knots,
which are arranged at intervals along their course, and which
refract the light more strongly. ‘These pseudopodia are recti-
linear, slow of movement, and coalescent ; and by the combi-
nation of these peculiarities they vividly recall those of the
Foraminifera.
When the little creature thus formed becomes active, it
abandons the spherical form and extends itself, more or less,
in one direction by a general contraction of its body. The
physiognomy which it then takes on varies much less than in
other Protozoa; it is usually that of a Savoy biscuit, inflated
at the extremities and slightly narrowed in the middle, the
inflated extremities being the seat of the emission of the
pseudopodia (fig. 4).
Sometimes the body becomes triangular, with pseudopodia
radiating from each of the heads; more rarely it is quite
irregular, with pseudopodia springing from all the little salient
angles which are marked in its outlines (figs. 3 & 5).
It is evident that, under these aspects, Monobia confluens
feeds and nourishes itself. I have not witnessed the pre-
hension of food, and I cannot say what part the pseudopodia
take in it. But it is certain that foreign bodies, often in
considerable number, are to be seen in the mass of the
body, sometimes each contained in a vacuole produced by
their liquefaction, and representing the product of their diges-
tion, not yet mixed with the general mass. The pseudopodia
do not appear to me to be adapted to digest on the spot; at
least this seems to follow from the fact that I have never seen
them involve foreign bodies.
I have stated above that Monodia is destitute of vacuoles :
by this I mean contractile vacuoles ; for we have just seen that
such cavities are formed in connexion with digestion, as in the
Amabe.
As soon as the Monobdia has thriven so as to double its size
or thereabout, it propagates, in accordance with the immu-
table law that 1eproduction is the overflow of nutrition. We
then see it elongate strongly, contracting and drawing
390 M. A. Schneider on a new Moneron.
itself out in the middle, until it presents the appearance of
two spheres united by a band of sarcode. This band may
become attenuated until it is no thicker than an ordinary
pseudopodium ; this filament may give way in its turn; and
then we have two individuals instead of one. But most com-
monly this is not the course of events, and the two fractions
of the division, although each acts independently, continue to
hold one another, as it were, by the hand, like two sisters
(fig. 2). They not only do not rupture the more or less
attenuated thread which is interposed between them, but, as
I have often witnessed, it also happens that two of their
pseudopodia meet and become fused together, so as to set
up a second point of communication parallel to the former.
Whenever two pseudopodia issuing thus from two different
centres meet together, there is an amalgamation of the pseudo-
podia. ‘This amalgamation effected, the bond of union be-
comes widened by afflux of plasma, and the communication
between the two sarcodic territories is widely open, so that
the granules can pass from one to the other. This mechanism
explains the very varied aspects, changing from day to day,
which the same colony presents.
Starting from a single individual, we have just seen how we
get to two, which sometimes separate and sometimes remain
connected. Each of the two new individuals, behaving like
the first after the lapse of a certain time, we get to four, all
united to one another like the links of a chain. I have
counted as many as eight thus associated; and their line ex-
tended over a considerable distance, describing a slight curve
(fig. 7).
The following day this was no longer the state of affairs.
Each member of the colony had pulled upon the common cord ;
and a new resultant had been produced from these opposite
caprices. My Monera were now grouped as shown in
fig. 8—in a square surmounted by a triangle, the latter
surmounted by an arrow. ,
