THE OCCURRENCE OF EHUGYRINA GIGANTEA (LAM.) IN
BRITISH WATERS.
By the Rev. A. H. Cooxer, Sc.D., F.Z.S.
Read 12th November, 1915.
By the kindness of a friend I have come into possession of a specimen
of Lugyrina (formerly known as Fanella) gigantea, Lam., from British ~
waters. ‘he specimen, which was alive when taken, measures exactly
5 inches in length, and still retains the operculum. It was trawled
(there were several specimens in all) in the deep trough (50 to
100 fathoms) off the Saltees lightship, between Carnsore Point and
St. David’s Head, in company with Cassidaria rugosa, L.
Unless I am mistaken, the discovery of this species constitutes an
important addition to the British marine molluscan fauna.
Five specimens were exhibited before the Conchological Society in
May, 1915, having been dredged alive off the south-west coast of
Ireland in deep water, also with C. rugosa. Butno precise statement
is published ' as to the locality, which may or may not have been within
the British marine area. In any case, the present specimen comes
from waters which are essentially British, and the locality is by far
the most northern hitherto recorded.
The species is common in the Mediterranean, and it is probably an
accident that all Weinkauff’s localities (ii, 71) are west of Tarentum.
Kobelt (Iconogr. ii, 1901, pp. 11-138) records it from the Atlantic only
up to the mouth of the Tagus. The Z)-availleur had many years before
dredged it in the Bay of Biscay (Jeffreys, Ann. Mag. Nat. Hist.,
ser. v, vol. vi, 1880, p. 318). Dautzenberg records? it from the
voyage of the Hirondelle (1886), from various localities in the Bay of
Biscay, from lat. 43° 12’ to 45° 48’ N. and long. 5° 58’ to 11° 52’ W.,
at depths varying from 160 to 510 metres, in fine sand, coarse gravel,
mud, and rock. He also adds that it was met with in the Gulf of
Gascony by the Zravailleur and the Porcupine, and that it is frequently
brought up by the fishing-boats from off Arcachon.
Finally, A. Reynell, recording the results of the cruise of the
S.8. Hualey to the northern side of the Bay of Biscay in August,
1906, mentions® Ranella gigantea as dredged in 109 fathoms (four
living specimens—two male, two female) from lat. 47° 48 N.,
long. 7° 46’ W., adding ‘‘the most northerly habitat of this species
so far recorded ’’.
It appears doubtful whether Locard’s view will hold good, that the
Atlantic shells differ sufficiently from the Mediterranean to justify
the constitution of two varieties, atlantica and mediterranea. The
form atlantica is said to occur in the post-Pliocene of Italy.
In accordance with Dall’s classification’ of the Ranellide and
Tritonide, the Ranella gigantea of Lamarck is now separated from
the former group, and is at present the sole occupant in the British
Museum Collection of the genus Hugyrina of Dall.

A NEW BRITISH LOCALITY FOR HELIX (EUPARYPHA) PISANA,
MULL.
By the Rev. A. H. Cooxs; Se.D., F.Z.8:
Read 10th December, 1915.
Dorine a visit to Porthcawl (Glamorgan) in August of the present
year, I was struck by the occurrence of Helix pisana, Mill., on the
sand-hills to the east of the town. Specimens were present in hundreds,
clinging, as usual, in masses to the stalks of the herbage.
It seems obvious that the species must have been introduced by the
agency of man, and probably within the last few years. Although
the ‘burrows’ at Porthcawl extend for a distance of perhaps two
miles along the coast, and offer what seems a suitable habitat through-
out, the species only occurs at present, so far as I was able to ascertain,
for the few hundred yards immediately adjacent to the town, just
where the bathing tents are pitched. It seems clear that the
introducer put his specimens down on the first suitable ground he
came to, where they at once increased and multiplied, but they have
not yet had time to extend their area of occupation over more than
a small section of the sand-hills. It is quite probable that the species
was introduced from Tenby, which is hardly more than four hours
journey from Porthcawl by train.
Not all attempts to colonize Helix pisana in Glamorgan have been
so successful. Jeffreys made two attempts, at an interval of years,
to colonize it on the sand-hills near Swansea, but the experiment
failed. According to J. W. Taylor,? ‘‘Mr. H. Rowland Wakefield
now entirely omits it from his list of Swansea shells, as he has
regularly and persistently searched the district for some years past, in
conjunction with the local Field Club, without finding a trace of
a single shell, though recently he has picked up a few dead specimens
at Singleton.”
Perhaps one of these local Field Clubs may be able to furnish some
definite information as to when and how the Porthcawl colony was
started, which seems to have a more brilliant future before it than
that at Swansea.

THE OPERCULUM OF THE GENUS BURSA (RANELLA).
By the Rev. A. H. Cooxe, Sc.D., F.Z.S.
Read 14th January, 1916.
W. H. Datt, in his well-known and admirable paper,! ‘‘ An Historical -
and Systematic Review of the Frog-Shells and Tritons,” draws up
a classification, which results in the following grouping :—
Genus Bursa.
A. Sub-genus Bursa.
Operculum with lateral nucleus:
(a) Sect. Bursa (spinosa, Lam.).
(6) Sect. Marsupina (spadicea, Mtf., or crassa, Dillw.).
(c) Sect. Chasmotheca ( foliata, Brod.).
Operculum with apical nucleus :
(d) Sect. Ranella (bufonia, Gmel.).
(e) Sect. Lampadopsis (rhodostoma, Beck).
(f) Sect. Colubrellina (conditus, Gmel.).
B. Sub-genus Aspa.
Sect. Aspa (marginata, Gmel.).
C. Sub-genus Bufonaria.
(a) Sect. Crossata (ventricosa, Brod.).
(6) Sect. Bufonaria (serobilator [ sic], L.).
(e) Sect. Craspedotriton (convolutus, Brod.).
It will be noticed that the characteristics of the operculum, given
in the above classification, affect only one of the three sub-genera
(Bursa), while of the operculum of the two remaining sub-genera
(Aspa, Bufonaria) nothing is stated.
Dall further remarks: ‘‘ According to Adams the Ranella have the
operculum ovate, with an apical or subapical nucleus, while Gray
speaks of it as half-ovate with a central, lateral, or internal nucleus ;
probably it varies in the different groups as in the Tritons ; in anella
Joliata it is figured as concentric, with the nucleus mid-lateral. One
cannot safely generalize on the character until the operculum of more
species 1s known.”’
In view of this last remark I venture to put on record the facts, so
far as they are known to me, of a considerable number of species
of the genus Bursa. If students to whom are known the opercula of
other species not in the list will gradually add to the number, a more
or less complete body of evidence will in the end be accumulated.
No final classification of a group can be regarded as settled until full
information of this kind is in our possession.
It must be premised that Dall published no list of species contained
in each of his several groups or sections, but only a type species in
each case. J have therefore worked the list as interpreted by the
* Smiths. Coll., xlvii, 1904, pp. 114-44.

Natural History Museum in their show-cases. The only difference
between their grouping and Dall’s is the nominal substitution of
Tutufa, Jouss., for the sub-genus he calls Bufonaria.
Nothing is commoner than for opercula to be misplaced, turned
upside down, outside in, and even located in shells they do not belong
to. Great caution is needed in order to avoid mistakes.

With regard to the section Craspedotriton, Kesteven has shown '
that the operculum and radula of convolutus, Brod., are those of
Trophon, not Bursa; it is probable, therefore, that scalariformis,
Brod., and scalarina, A. Ad. (= speciosa, Ang.), will also prove to be
Trophons: the section therefore drops out.
The details of the known species are as follows :—
A. Sub-genus Borsa.
(a) Section Bursa.
General characteristics: operculum rather thin, more or less
transparent, almost triangular, with longer side rounded, nucleus
sub-lateral, to the left (¢.e. adjacent to the columella), nearly central,
clear of the margin, lines of growth prominent.
1. albifasciata, Sowb. A somewhat broken operculum is attached
to the tablet in M.B., nucleus to right, sub-lateral, half-way between
centre and lower end. In other words, if the operculum belongs to
the shell, which I doubt (the shells are Cuming’s), the species must
be removed, probably to section Ranella or Colubrellina, from which,
conchologically, it is quite distinct.
2. erumena, Lam. Nucleus well marked, lines of growth flattened.
3. elegans, Beck. As in spinosa, not transparent, colour deep brown.
4. margaritula, Desh. Rather less pointed at top and bottom than
the other species, dark brown, lines of growth not very prominent.
5. nana, Sowb. ‘Two opercula are attached to the tablet in M.B.
(Cuming’s specimens), one rather long, narrow, nucleus sub-terminal,
the other more ovate, light-coloured, nucleus sub-marginal, to right,
below the centre. It is clear that both of these cannot be the true
opercula, and I am inclined to regard them both with suspicion.
6. rana, L. ‘Thin, transparent, lines of growth very sharply
marked, and occasionally rising into broad raised ridges.
7. spinosa, Lam. Not angled, but rounded, against the columella,
thicker than in rana, lines of growth not elevated.
8. thersites, Redf. Rather thin, nucleus very near the margin,
a little below the centre.
1 Pyoe. Linn. Soc. N.S. Wales, vol. xxvii, 1902, p. 479. Dall, though writing
his paper on the Frog Shells in 1904, does not seem to have seen Kesteven’s
paper, as he expressly says (p. 13), with reference to scalariformis and
convolutus, *‘ their operculum is not known to me.’’
8 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
Sections I/arsupina and Chasmotheca.
It seems doubtful whether these sections embody any valid
distinction from Bursa, s.str. The operculum of crassa, Dillw., does
not appear to be known; Dall states that that of fol/ata is as in rana.
(0) Section Panella.
General characteristics: nucleus to right, thicker than in Bursa,
not well marked, lateral, sub-terminal.
1. bufonia, Lam. Rounded above, narrower below, nucleus very
indistinct, close to the right of terminal margin.
2. stphonata, Rve. Rounded above and below, nucleus better
marked and rather higher up than in bufonva.
tuberosissima, Rve. Almost exactly as in stphonata.
(ce) Section Zampadopsis.
General characteristics: more or less as in Ranella.
1. asperrima, Dunk. Thin, ovate, transparent horn-colour, nucleus
terminal, well marked, slightly to the left, lines of growth well
marked. This operculum differs markedly in character from the
others in the section.
2. eruentata, Sowb. Thin, rounded above, somewhat angled below,
nucleus sub-terminal, to right, fairly well marked.
3. rhodostoma, Desh. ‘‘ Nucleus lateral, submarginal, to the right
and sub-terminal, like that of s¢phonata” (Ph.D.).
4. thome, Orb. Thin, ovate, nucleus sub-marginal, to the left,
sub-terminal, indistinctly marked.
(d) Section Colubrellina.
General characteristics : operculum ovate, sometimes semi-
unguiculate, thickish, narrower below than above, nucleus rather
obscure, sub-terminal, or sub-lateral to the right.
1. granularis, Bolt., with vars. afinis, Brod., livida, Rve., ponderosa,
Rve. The nucleus varies slightly in position ; in two typical granu-
laris (= granifera, Lam.) from M.M. the nucleus is sub-terminal,
in a divida from M.M. and an affnis from J.R.T. it is obscurely
sub-marginal, to the right, and sub-terminal. Ph.D. remarks to me:
‘‘opere. a nucléus latéral, marginal, situé, soit au dessous du milieu,
soit méme presque a l’extremité.”
2. celata, Brod. Shape almost semi-unguiculate, nucleus well
marked, sub-terminal, but well away from the margin, lines of
growth well marked, rising into ridges in old specimens.
3. pustulosa,| Rve. Shape semi-unguiculate, nucleus almost
terminal, closely resembling that of celata.
4. semigranosa, Lam. Many consider this species another variety
of granularis. Operculum thin, nucleus obscure, sub-marginal, to
right, sub-terminal, as in granularis.
' This species, from West Africa, St. Helena, and Ascension, must surely be
regarded as distinct from celata, Brod., a Panama shell which does not
occur in the West Indies.
DR. COOKE: OPERCULUM OF THE GENUS BURSA. 9
B. Sub-genus Aspa.
Section A spa.
marginata, Gmel. (the only species). Operculum thin, semi-
transparent, lines of growth clearly marked. Shape as in Bursa,
but not so triangular, nucleus similarly situated, slightly more
removed from the left margin.
C. Sub-genus Bufonaria.
(a) Section Crossata.
General characteristics: operculum ovate, rounded at both ends,
thick, dark horn-colour, lines of growth obscure, a nucleus indicated
but not existing, lateral, sub-terminal, to right.
californica, Hinds. Opercnlum as in the section. In a remark-
ably fine and clear specimen from McA. there is almost a visible
nucleus on the margin low down on the right.
2. ventricosa, Brod. Operculum a little wider than in californica,
but in other respects generally corresponding.
(6) Section Bufonaria (= Tutufa, Jouss.).
1. rubeta, Bolt. (=lampas, auctt.). Operculum sub-ovate, not very
thick, rounded at top, angled below, nucleus distinct, sub-lateral, to
right, well away from margin, below the centre, lines of growth
well marked, but not raised in ridges.
2. scrobiculator, L. Operculum sub-ovate, rather thin, semi-
transparent, rounded above and below, nucleus distinct, sub-lateral,
to right, well away from margin, below centre, lines of growth well
marked, but not raised in ridges.
On a general survey of the evidence afforded by the operculum,
the following points seem to stand out :—
1. There is a large group of Bursa (Bursa, s.str. + Chasmotheca
+ ? Marsupina) with a more or less triangular operculum, nucleus
well marked, in the centre of the left sub-margin.
2. Closely allied to this group stands the sub-genus Aspa,
conchologically different, but with an operculum of similar general
construction.
3. Another large group (Ranel/a + Lampadopsis 4 Colubrellina)
possesses an ovate operculum, with nucleus to the right or near the
extremity, generally less well marked, sub-marginal or sub-terminal.
Closely allied to this group, and possibly not separable from it, are
the species contained in section Bufonaria.
4. Further removed comes a group (Crossata) geographically
separate from the Bufonaria section, and with an operculum not
essentially dissimilar to that of certain species of Zriton (Lotorium).
As Dall has remarked, ‘the Ranellas shade very gradually into
the forms formerly known as Triton, judged by most of their
characters,” and it is interesting to observe how, on the one hand,
Gyrineum and Eugyrina carry the “ Ranella” shape of shell, minus

low-spired forms of Zotortwm is carried into the Crossata group of
“* Ranella’’.
The evidence, then, of the operculum, plus certain other con-
siderations which have appeared in this paper, would lead one to
throw out the suggestion that perhaps Dall’s classification might
with advantage be modified in the following way :—
A. Sub-genus Borsa, containing in a single section Bursa, s.str.,
Chasmotheca, and probably Marsupina.
Fic. 1.—Median teeth of :—1. Bursa granularis, Bolt., Umkomaas, Natal.
2. Triton (Lotorium) australis, Lam., Port ‘Jackson. 38. Crossata
ventricosa, Brod., Orange Harbour, Tierra del Fuego. 4. (Triton)
leucostoma, Lam., Port Shepstone. 5. Hugyrina gigantea, Lam.,
Algiers. 6. Crossata californica, Hinds, San Pedro, Cal. All from
Professor Gwatkin’s collection.
B. Sub-genus Aspa.
C. A sub-genus (Ranerra would be a convenient title) including
all the sections whose operculum is sub-marginal, generally but not
always to the right, or sub-terminal, viz. Ranella, Lampadopsts,
Colubrellina, and Bufonaria.
D. A sub-genus (call it Crossata if you like) including the two
species californica and ventricosa, the form of whose shell and shape
of whose operculum approximate towards the ‘‘ Tritons”’.
DR. COOKE: OPERCULUM OF THE GENUS BURSA. El
The evidence of the radula, as kindly given to me by Professor
H. M. Gwatkin, may be stated thus :—
An examination of twenty-six species and varieties shows three
types of radula.
1. A Bursa type, which includes all the typical Burse, viz. bufonia,
calata, cruentata, crumena, granularis and varieties, pustulosa, rana,
rhodostoma, semigranosa, siphonata, spinosa, thome.
Under this type also, but somewhat distinct from it, come
(a) marginata, with radula of so delicate proportions that it stands
somewhat apart from the others, and (d) rudeta, of the typical form,
but much stronger and stouter.
2. A Triton (Lotoriwm) type (i.e. a median tooth with strong
central denticle and several small side denticles) including perca,
pusilla, tuberculata, vexillum, and argus, but not gegantea or leucostoma.,
(N.B. These radule of the ‘‘ Triton” type are by no means typical
eeTiripons ’?,)
8. A type unlike both Bursa and ‘‘ Triton”? proper, and including
californica, ventricosa, gigantea, and leucostoma, ‘he median exhibits
one great central denticle, and is almost bare of side denticles in
californica and gigantea: ventricosa combines the big central denticle
with the lateral prolongations of a Bursa (Fig. 1).
I have to express my thanks to Mr. R. Standen, of the Manchester
Museum, to the authorities of the Museum of Zoology at Cambridge,
to Dr. J. C. Melvill, and Mr. J. R. Le B. Tomlin for the kind loan of
specimens, now exhibited, and also to M. Ph. Dautzenberg for valuable

ON A COLLECTION OF PELECYPODA FROM THE PHILIPPINE
ISLANDS.
By Enear A. Suirn, 1.8.0.
Read 12th November, 1915.
PLATE I.
Trts small collection, submitted to me for determination, is not of
very special interest beyond the fact that it comprises a number
of species not previously recorded from the Philippine Islands, with
seven which appear to be undescribed.
The specimens were all collected at Port Galera, a small bay
almost completely landlocked, on the north coast of Mindoro, opposite
the town of Batangas, on the island of Luzon.
Of the fifty-nine species enumerated rather more than half have
already been recorded from the Philippines, and those which appear
to be new to the fauna are marked with an asterisk. The identifica-
tion of the specimens! has been much facilitated by the catalogue of
the Pelecypoda of these islands published by Dr. J. G. Hidalgo in the
Mem. R. Acad. Ciencias Madrid, vol. xxi, 1903, pp. 1-v, 1-400, and
in the Revista R. Acad. Ciencias Madrid, vol. ii, 1905, pp. 246-312,
and vol. iii, 1905, pp. 9-43.

B. NOTES ON SOME OF THE SPECIES.
Papura macropon, Deshayes, Proc. Zool. Soc., 1854, p. 339, as
Mesodesma; Reeve, Conch. Icon., vol. viii, fig. 238.
The locality of this species was not known to Deshayes or Reeve,
and Hidalgo has not recorded the species in his list of Philippine
Pelecypoda.
Caxiisra Roskorrncra, Smith, Rep. Challenger Lamellibr., 1885,
p- 186, pl. i, figs. 6-60.
When describing this species I suggested that it probably attained
larger dimensions than those then given. In a series of specimens
in the present collection one example is 20°5 mm. in length, which is
only 3mm. larger than the type. I am now inclined to think that it
does not become much larger. The general tone of colour is rather
like that of ‘‘ Dione festiva”’ as given by Reeve (Conch. Icon., vol. xiv,
Dione, pl. i, fig. 2). Usually there are at intervals zones of a darker
tint than the ground colour, and in some specimens there are distinct,
more or less interrupted rays. In the fresh specimens at hand the
interior of the valves is whitish round the margin, but purplish
elsewhere, with a pale ray from the umbo downwards, All the
specimens have the tips of the umbones rosy pink.
Anticona (CrrcompHatus) FoLracEa, Philippi, Abbild., vol. ii, 1846,
p.alO7 spl. 2, fie. 1.
The specimens in the present collection belong to that form of the
species figured by Reeve (Conch. Icon., vol. xiv, figs. 109 and 110)
SMITH : PELECYPODA FROM THE PHILIPPINES. 15
as Venus tiara, Dillwyn, and by Sowerby (Thes. Conch., vol. 1,
1853, pl. elviii, figs. 125, 126) also as dzara.
This variety differs from the typical form of the species, as figured
by Philippi, in having the concentric lamine more prominently
foliated posteriorly, a groove down the dorsal slope, a little distance
from the margin, cutting through the lamelle and thus forming an
upper or marginal series of short Jamelle. ;
GLyYcIMERIS PECrUNCULUs (Linn.), var.
The single specimen in the present collection is flatter than usual,
and the coste are more slender than in normal examples, and
consequently the intervening grooves are broader. Another slight
distinction is the absence of brown colour on the hinge-plate,
a conspicuous feature in G. pectunculus and G. muskatensis, Melvill.
The latter attains much larger dimensions than those given by the
author of his type. Specimens in the British Museum from Muscat,
presented by Dr. Jayakar, are 41 mm. high, 43 long, and 27 in
diameter, in fact almost double the size of Mr. Melvill’s shell.

1868, p. 23, as Pectunculus.
= Pectunculus angulatus, Reeve (non Lamarck), Conch. Icon., vol. i,
fig. 30.
A number of young shells 16-19 mm. in length appear to be
immature examples of this species. At this stage of growth the
sculpture is more raised, the radiating threads and concentric stris
which cross them producing a granose surface. The radiating threads
are in groups of about four or five on the middle of the valves, the
groups being marked off by pale striz. At the sides they are not in
groups, and between them the grooves exhibit very short bristles.
The colour is variable, usually light or dark brown with irregular
white blotchings.
Guycimeris pLanatus (G. & H. Nevill), Journ. Asiat. Soc. Bengal,
vol. xlili, pt. 1, 1874, p. 29, pl. i, figs. 16, 16a, as Pectunculus.
This Pecten-like species has hitherto been known only from the
Andaman Islands. ‘he colour was described as ‘‘ white, mottled,
and variegated with brown.” The specimens from the Philippine
Islands are white spotted with red, the spots being only on the
radiating ribs, and disposed in irregular concentric rows. ‘The interior
is white with a faint purplish stain below the umbones down the middle
of the valves. One or two of the costz on each side near the hinge-
line are slender, simple, and not grooved down the middle like those
on the rest of the shell. The largest specimen is 20°5 mm. in height,
21 long, 10°5in diameter. A specimen from the Andaman Islands in
the British Museum is about the same size.
C. DESCRIPTIONS OF THE NEW SPECIES.
PsaAMMOBIA PHILIPPINENSIS, n.sp. Pl. I, Figs. 16-18.
Shell transversely elongate, slightly inequilateral, anterior portion
rather the longer, sharply rounded at both ends, somewhat more
16 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
acuminate behind, white with a few remote brown marks on the
dorsal margins both in front and behind the umbones; both dorsal
margins only slightly oblique, ventral margin little arcuate in the
middle, but curving upward at both ends; valves thin, sculptured
with fine growth-lines, crossed by fine threads which radiate from
the umbones, the thread towards the hinder end being more distinct
than those in front; upon the posterior excessively fine striz are
observable which curve from the margin towards the other radiating
threads ; umbones brown at the tip, inthe form of a minute glossy
boss or knob of a different texture to that of the rest of the shell;
interior of valves glossy white ; hinge-characters normal ; pallial sinus
tongue-like, rounded at the end, not reaching quite half-way across
the valves.
Length 8°5, height 4°75, diameter 3mm.
This species resembles P. candidula, Deshayes, somewhat in form,
but it is very differently sculptured. The generic term Gari! of
Schumacher is used by some authors as being anterior to Psammobia
of Lamarck, but to employ a word with a genitive termination as
a genus hardly seems admissible.
PETRICOLA DicIraLE, n.sp. Pl. 1, Figs. 7, 8.
Shell small, sub-quadrate, rather convex and inequilateral, white,
slightly iridescent, thin, sculptured with excessively fine criss-cross
raised threads, so that the surface presents a punctate appearance
rather like a thimble; here and there at intervals shallow waves of
growth are also observable; anterior end obtusely rounded, posterior
broader, curvedly sub-truncate, ventral margin straightish, not much
curved ; anterior dorsal edge oblique, slightly curved, posterior longer,
straighter, less descending; lunular area large, defined by a distinct
curved impressed line in each valve, extending from the umbo to the
end of the dorsal slope; the surface, unlike the rest of the shell,
for the most part exhibits lhttle punctation, but merely the most
delicate growth-striz. Umbones raised a little above the hinge-
margin, contiguous, smooth, with only delicate growth-strie ; three
cardinal teeth in the left valve, the central one thick, A-shaped, the
others oblique, one on each side divergent from the umbo; right valve
with two divergent slender teeth which fall, when the shell is closed,
one on each side of the central tooth of the left valve; adductor scars
large, anterior pyriform, posterior a little broader ; pallial sinus large,
broad, ascending high and beyond the middle of the valve, rounded at
the end; hinge-ligament occupying about half the posterior dorsal
margin, yellowish.
Length 6, height 5°5, diameter 4mm.
This shell has not the appearance of being the young of a larger
form, since it is considerably convex, and rather like certain forms of
Spherium or Kellia in general aspect. The surface to the naked eye
appears smooth, and the punctate or thimble-like appearance of the
surface is only visible under a lens.

SMITH : PELECYPODA FROM THE PHILIPPINES. ul
The young of P. lapicida (Chemnitz) Gmelin, has somewhat the
form of this species, but the sculpture is different, being coarser, and
it has no definite lunular area. A single valve from Flinders Passage,
North Australia, recorded in my report on the Challenger Lamelli-
branchiata, p. 118, belongs to the present species and not to P. lapicida.
Dosinra supaxata, n.sp. Pl. I, Figs. 11-13.
Shell subcircular, moderately convex, rather thin, white with rosy
tips to the umbones, very delicately concentrically striated at first
and then rather more distantly towards the base, the threads between
the strize smooth upon the central part of the valves and becoming
finely lamellar both anteriorly and behind; lunule elongate-cordate,
prominent in the middle, fairly striated; escutcheon raised and keeled
down the middle, defined by a shallow depression in each valve
extending from near the umbones nearly the whole length of the
posterior dorsal margin; the valves at this part consequently exhibit
a narrow wing-like prominence; interior of valves whitish ; anterior
adductor scar narrow, elongate, posterior pyriform; pallial sinus
long, tongue-like, extending some way beyond the middle of the
valves, blunt at the end; hinge normal.
Length 25, height 24, diameter 11 mm.
Allied to D. lucinalis, Lamarck, of which D. striatissima, Sowerby,
is a synonym. The concentric sculpture of the present species,
however, is finer, and it lacks the radiating strive of D. lueinalis. The
form of the latter is somewhat different, being shorter in proportion to
the height. ‘The pallial sinus is considerably longer in D. subalata.
D. celata, Reeve, is even more closely related, and differs only in
having stronger lamelle in front and behind, a larger and much
deeper dorsal area marked off by asharper cristate keel, and a slightly
shorter pallial sinus.
Antigona (VENTRICOLA) MINDOoROENSIS, n.sp. Pl. I, Figs. 1-3.
Shell sub-globose, very inequilateral, white, with four curved,
sub-equidistant, reddish rays, concentrically delicately lamellated, the
lamelle being thin, erect, and cross-striated on the lower side ; between
the lamelle the surface exhibits fine thread-like lines, four or five
in each interval, also excessively minute curved radiating strie ; lunule
broadly cordiform, brown, sunken except in the middle, where it is
a little raised; marked with fine raised lines of growth; escutcheon
deep, defined by a sharp keel in the left valve, upon which the lamelle
terminate; the portion of the escutcheon in the right valve is smaller
than that of the left and less sharply defined, the lamelle extending
further over towards the edge of the valve; umbones yellowish or
pale brown at the smooth tips which curve forward over the lunule ;
interior of the valves white outside the pallial line, very faintly
tinted with a kind of flesh tint within the pallial line, which is shortly
angularly sinuated; inner edge of the valves very finely crenulated
all round excepting on the hinder dorsal margin, the crenulations on
the edge of the lunule being finer than those on the ventral edge;
anterior adductor scar ovate, posterior larger, sub-reniform.

18 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
Length 30, height 28, diameter 16 mm.
A specimen in the British Museum, said to come from Hong-Kong,
is a little larger than the Philippine specimen, being 37 mm. long,
35 high, and 21 in diameter.
V. rigida, Dillwyn, of which V. pilula, Reeve, is a synonym, in
some respects resembles the present species. It is, however, rounder,
more globose, differently coloured, has less erect and less delicate
lamelle, and the spotting on the escutcheon, in the left valve only, is
peculiar. It isa West Indian shell.
Luctna EvGLyeTa, n.sp. Pl. I, Figs. 4-6.
Shell irregularly rounded, inequilateral, white, concentrically
finely closely lamellated and radially costate between the lamelle,
which are finely frilled through crossing the coste ; valves moderately
thick, with a depression marking off a wing-like portion below the
straight posterior dorsal margin; lunule very small, deep, under
the umbones, which are contiguous, but the tips curl away over the
lunule; beyond this there is another ill-defined lunular space
enclosed by a slight curved depression on the valves; there are no
radiating costelle upon the hinder wing-like portion of the valves, or
upon the lunular space, and consequently the concentric lamellee are
simple and not frilled; interior of the valves white, with the lower
margin slightly denticulated; posterior adductor scar pyriform,
anterior narrow, long; dentition normal.
Length 17, height 16, diameter 9 mm.
This species bears some resemblance to LZ. gemma, Reeve, in respect
of the wing-like hinder part of the valves. There is a great
difference in the surface ornamentation of the two species. JZ. gemma
has no radiating coste between the concentric lamelle, which are
beautifully denticulate or serrate. It is also a much flatter species
than that now described.
Luctna TRANSVERSA, n.sp. Pl. I, Figs. 9, 10.
Shell oblong, transverse, almost equilateral, white, concentrically
finely ridged, finely yet roughly radiately striated between the
concentric ridges or lire; valves rounded in front with a cristate
keel behind, marking off an elongate, lanceolate escutcheon exhibiting
only fine growth-lines; lunule sunken, elongate, marked with fine
lines of growth ; umbones smooth at the tips, contiguous; the posterior
keel, which is crested with the concentric lamelle, forms a point at
the hinder end of the valves; interior white; posterior adductor scar
rounded except above, where it is as if truncate; anterior scar short,
irregularly ovate.
Length 10°75, height 8, diameter 4°75 mm.
Allied to Z. fabula, Reeve, but more closely concentrically ridged,
and not so strongly or regularly striated between the ridges. There
are also differences in form.
GuLycIMeRIs MINDOROENSIS, n.sp. Pl. I, Figs. 14, 15.

these are about twenty-four in number, rounded, sub-equal, excepting
a few on each side near the umbones which are more slender. ‘The
sulci between the ribs and the costz also are crossed by very fine
crowded lamelle; the valves are rather thick, having the shorter
side (that towards which the umbones incline somewhat) rather
straight, the opposite end and the ventral margin being broadly
curved. The interior is white, stained on the anterior side with -
reddish brown; lower and lateral margins coarsely dentate ; hinge-
teeth, about twelve, arranged in a curved line; anterior adductor
scar roundish, posterior elongate-oval.
Length 9, height 9, diameter 5-5 mm.
Somewhat resembling G. hoyle’, Melvill & Standen, from Torres
Straits, but with the umbones more curved over anteriorly, higher
in proportion to the length, fewer and coarser hinge-teeth, the ribs
are devoid of tubercles, and the concentric fine raised strive or
lamelle are continuous on and between the coste.
Although it is impossible to say that the shell described is adult,
it does not look as if it would attain much larger dimensions.
For so small a shell the hinge-plate is very thick, and the teeth
are strong. The lines of growth are very crowded, and, being
continuous over and between the ribs, they have a wavy appearance.

ON THE SHELLS OF THE SOUTH AFRICAN SPECIES OF THE
SEPIIDA.
By Enear A. Smirg, 1.8.0.
Read 14th January, 1916.
PLATE II.
Some time ago a collection of Mollusca from South Africa was sent
me for determination by Mr. H. C. Burnup, of Maritzburg, Natal.
It contained a number of ‘‘ bones’ or shells?! of cuttlefishes, the
identification of which necessitated the study of all the South African
forms.? Since the collection contained some new species which had
to be described, it seemed it might be useful to offer at the same
time some notes on all the South African forms. Although I am
unable to give any account of the animals of the new species, the
shells appear to possess certain constant reliable characters by which
the species can be recognized.

M. d’Orbigny suggested that this species and S. hierredda of Rang
are synonymous, and, judging from the shells only, I am inclined to
think he was correct. Certain differences which have been described
in the coloration of the animals of the two forms may not, I think, be
of much importance.

A large shell of this so-called species from Lagos, presented to the
British Museum by Sir Alfred Moloney, is about 230 mm. in length.
This form is narrow, elongate, rather pointed at the anterior
end, considerably thick about the middle of the ventral side. The
chitinous margin spreads over the dorsal surface at the hinder end.
The back is pale down the middle, becoming very pale reddish at
the sides. ‘here is scarcely any noticeable central ridge and the
surface is finely granulated, the granules sometimes ranged in series
following the lines of growth down the middle of the back.

Hab.— Tongaat, Natal (H. C. Burnup) ; Zanzibar (G. Pfeffer).
A single shell from Tongaat agrees in every respect with the -
description and figure, but is much lar ger, having a length of 255 mm.
The dorsal surface, not referred to by Dr. Pfetfer, is coarsely wrinkled
towards the posterior end, the wrinkling becoming gradually more
feeble anteriorly.
This species is remarkable for the very broad, deep central
depression on the ventral side, and for the great development of
the deep inner cone, which is lined with a thick calcareous deposit
and has a chitinous outer covering. The yellowish chitinous margin
of the shell is well developed all round, and united above, but free
from the end of the inner cone, The spine is short and strong, and
arises from a much thickened shelly margin. Colour white, excepting
an obscure reddish ray on each side, diverging from the posterior end.
Sepra acuminata, n.sp. Pl. II, Figs. 3, 4.
Shell elongate elliptical, conspicuously tapering and becoming
pointed anteriorly ; striated area flattish or a little concave, occupying
more than half the total length, with a shallow central groove and
a few faint strie radiating from the hinder end, causing the curved
transverse strie to be a little wavy. Chitinous margin broad
posteriorly, thinly lined with callus, which is a little thickened
beneath the spine, the thickening being ridged or striated. Limbs of
the inner cone thickened, united behind, forming a rounded angle,
horn-colour. Spine moderate, rounded, not keeled, generally directed
slightly dorsally. Dorsal surface reddish, excepting the corneous
margin, having a faint central ridge, finely wrinkled and granulated.
Length 103, greatest width 36, greatest thickness 9 mm.
Hab.—Port Elizabeth (J. H. Ponsonby and H. A. Spencer); Tongaat
Beach, Natal (H. C. Burnup).
A small specimen, 35mm. in length, described by Dr. G. Pfeffer as
S. venusta’ (= venustoides, Hoyle) from Zanzibar apparently closely
resembles the young of this species.
A specimen from Tongaat, 46 mm. in length (pl. ii, fig. 4), differs
from other examples of the same size in having the chitinous margin
more widely developed posteriorly, and the striated area is longer and
divided into three distinct areas, one on each side, and a central one,
twice as broad as the laterals. The latter are concave and separated
from the central area by a keel or ridge. The striz on both lateral
and central areas are elegantly curved.

Sepia papillata, Quoy & Gaimard, Voy. Astrolabe, Zool., vol. ii, 1832,
p. 61, atlas, pl. i, figs. 6-14.
Shell elongate ovate, in adult specimens sometimes contracted
somewhat anteriorly; striated area a little concave, with a median
groove or depression which is faintly continued upon the last loculus ;
inner cone shallow, rounded at the end, its limbs, of a pale brownish
colour, reaching almost half the total length, spreading more or less,
and sometimes somewhat pointedly produced posteriorly ; spine very
obtuse and short, with an excavation or pit between it and the margin.
The dorsal surface has a feeble central rounded ridge, with a faint
depression on each side, and is finely wrinkled everywhere, excepting
towards the hinder part, where the wrinkling becomes coarser. The
colour of the dorsal surface is pale reddish excepting the posterior thin
sides, which are whitish.
Length of Quoy’s type 76 mm., width 37.
Hab.—Port Elizabeth (J. H. Ponsonby and H. A. Spencer) ;
Tongaat Beach, Natal (H. C. Burnup); Cape of Good Hope
(Quoy & Gaimard).
One of the specimens presented to the British Museum by
Mr. Spencer is 134 mm. in length and 60 in width.
In general structure this species resembles S. mestus, Gray,’ from
Australia, but differs in the absence of the keeled spine, in the
expansion of the limbs of the inner cone being more narrowly
produced posteriorly, and in rather coarser dorsal wrinkling. The
almost obsolete spine appears to be a constant feature both in young
and old specimens.
Quoy & Gaimard do not describe this feature, but it is quite
possible they may have regarded it as an abnormality in their
specimen, since there is no evidence that they had other examples.
However, their figure 12, although somewhat crude, sufficiently
shows that their shell had an obtuse spine similar to those in the
series I have examined. It should be noted also that the limbs of the
inner cones are rather variable. Sometimes, as in the Astrolabe
figure, they do not expand much posteriorly. On the contrary, in
some specimens they spread considerably, and become rather pointed
posteriorly. I have given the above particulars, since the description
in the Astrolabe is very superficial and incomplete.

Andr., ohlmert, Andr., cucunorica, Mlldff., futterert, Andr., hermannt,
Gude, rettert, Rosen, funki, Ancey, sturanyana, Kob., all from
Central Asia.
By Mr. Tom Iredale: A beautiful collection of Tasmanian Chitons,
forwarded by Mr. W. L. May, of Sandford, Tasmania, that has
facilitated the detection of several errors, both of omission and
commission, that had previously escaped notice.

which, although not definitely localized, was with much probability
of correctness believed to be from the Inferior Volite of Dorset.
The fossil was among the largest recorded examples, being, although
imperfect at each end, more than 50mm. long.

OBITUARY NOTICE.
Ir is with much regret we have to record the death of William
Tompson Bednall. He was born at Leicester in August, 1838, and
educated at the Philological School, London. His first employment
was at the Jermyn Street Museum of Practical Geology, then under
the direction of Sir H. B. De La Beche.
In 18453 he emigrated to Australia and entered the service of the
Register, a prominent newspaper of Adelaide, South Australia. .In
1874 he edited a paper at Port Darwin in the Northern Territory.
But after two years in the Tropics he returned to the Register, upon
which he was engaged till his retirement in 1908. For several years
his health was delicate, and he died on July 25, 1915, in his
77th year, leaving a family of one married daughter and three sons.
All his life he was an enthusiastic conchologist. He is associated
with two splendid species which he discovered in the Northern
Territory, Voluta bednalli and Murex bednalli. Besides these two, of
which he was especially proud, the specific bednalli was adopted tor
Australian members of the following genera: Acanthochites, Chiton,
Drillia, Epidromis, Helix, Pecten, Trigonia, and Unio. For many
years he was honorary curator in Conchology to his State Museum.
He was one of the founders of the Royal Society of South
Australia, to the publications of which he contributed six articles on
Australian Mollusca. His best work was an article on the Polyplaco-
phora of South Australia in the ‘ Proceedings of the Malacological
Society of London’ (vol. ii, 1897, pp. 139-59, pl. xii and figs.). His
last conchological paper, also on Polyplacophora, written in association
with E. H. V. Matthews, appeared in the same journal (vol. vu,
1906, pp. 91-2, pl. ix).

NOTE.
THE OCCURRENCE OF THE LARVA OF A CestopE Worm IN POLITA ROGERSI.
(Read 10th March, 1916.)—In January, 1915, aspecimen of P. rogersz,
B. B. Woodw., was found near Radlett (Herts) which showed on dissection
the presence of larvae of some cestode worm in the lower part of the liver.
The cysts, some twenty in number, seem to lie free in the cavities of the
liver ; they are about 0'4mm. in diameter, with a pretty tough outer skin.
On rupturing this, the scolex is delivered, showing a bilobed appearance,
with the head sunk in a pit at one end. There are numerous calcareous
bodies. The hooks are, as far as I can see, eighteen or twenty in
number and about 0°05mm. long. ‘The other host of the parasite is
presumably something which eats the snail ; birds and voles suggest them-
selves. The foot and tissues of the snail had the peculiar pinkish
appearance which is sometimes seen in P. rogers? (Lancashire Naturalist,
vol. vii, 1914, p. 311). The eggs of the tapeworm can evidently pass
uninjured through the masticatory apparatus of the snail, which affords
further evidence that the radula is a prehensile rather than a grinding
apparatus.
A. E. Boycort.
P.S.—Since writing the above I have found apparently the same
parasite in six out of ten specimens of Poltta cellaria (the scharffi
form) and in two of twenty-one P. nitidula collected in August at
Sopwell Nunnery, near St. Albans. Mr. Bowell, who was with me,
recollects that mouse feces were abundant where the snails were.
P. rogersi was not found. A large number of Polita have been
examined from other localities in South Hertfordshire with negative
results.

NOTE ON TRIPHORA SMITHI, SOWERBY, AND T. GRACILIOR,
SMITH.
By the late Enear A. Surru, I.8.0., F.Z.S., ete.
Read 10th March, 1916.
TripHora suirut was described by Mr. G. B. Sowerby in these
‘‘ Proceedings”? (vol. vi, p. 174) from a single shell preserved in the
collection of the late Admiral Keppel. At the time (September,
1904) the locality was unknown, and the unique shell was referred
to as ‘larger than any other known species of the genus” excepting
T. princeps, described by Mr. Sowerby at the same time, also from an
unknown locality. The object of this note is to point out that
T. smithi had previously been described by myself as Z. gracilior,
that the species when adult is quite as large as 7. prineeps, and also
to give its geographical distribution as far as at present known.
The description of Z. gracilior was published on November 15th,
1908, in Stanley Gardiner’s Launa and Geography of the Maldive and
Laccadive Archipelagoes (vol. ii, p. 614, pl. xxxv, figs. 18, 19). The
species was founded on a single shell from the Maldive Islands,
which is preserved in the British Museum. It is 5mm. shorter than
Mr. Sowerby’s type, also in the national collection, having a length
of 28mm. In the year 1907 the Museum acquired a large selection
of shells from an extensive collection made at the Andaman Islands
by the late Rev. J. L. I’. Warneford, and among the specimens
obtained was a fine example of 7! gracilior, which if the top of the
spire had not been broken off must have measured almost 60 mm. in
length.
Mr. Sowerby has given the number of whorls of 7. smithi as thirty-
five, but in my examination of the type I can count only twenty-six.
Perhaps Mr. Sowerby may have allowed nine extra whorls for the
top of the spire which is wanting, but I do not think it would have
consisted of so many. He described the whorls as having 2-4
spirals, which is vague and not quite accurate, since each whorl
bears three spirals, the uppermost, below a fine sutural thread, being
a little more slender than the other two. The latter also are slightly
affected by faint longitudinal depressions, giving them an obscurely
beaded appearance. ‘I'his is noticeable in the types both of smithi
and gracilior, but is hardly apparent in the very large Andaman
specimen. ‘Lhe space between the second and third keel is a little
broader than that which separates the first and second, and the
suture is filo-carinate. The labrum in the adult is a trifle etfuse,
and exhibits within three grooves, which correspond to three of the
external spirals or carine, namely, the two peripheral ones close
together and one above more remote. The columella has a well-
defined callus extending from the junction of the outer lip above to
the end of the oblique anterior canal, which is not closed.
In conclusion, I may add that the figure of 7. smzthi does not give
any idea of the true sculpture of the species. That of Z. gracilior
in Mr. Stanley Gardiner’s work is fairly accurate.

NOTE ON PHOLAS COSTULATA, GOODALL.
By the Right Hon. Lord Watstnenam, M.A., LL.D., F.R.S., ete.
Read 10th March, 1916.
In 1890 I communicated to the Norfolk and Norwich Naturalists’
Society some remarks on a species of Pholas dredged by my father off
Hill Head, near Gosport, about 1819, and these were published in
the fifth volume of the Society’s Transactions (pt. 1, pp. 79-86, with
figures) accompanied by two interesting letters from Dr. J. Goodall
(then Provost of Eton College), to whom the specimens had been
sent, and who suggested (Joc. cit., p. 80) the name Pholas costulata, since
he considered it a distinct species allied to P. candida. In the same
communication is included a letter from Mr. Edgar A. Smith, 1.8.0.
(then in charge of the Conchological Collections at the British
Museum, Natural History), to whom I sent the original specimens,
and who expressed the opinion that they represented a depauperated
form of P. candida.
Pholas costulata, Goodall.—Original woodcut, from the Trans. Norf. and
Norwich Nat. Soc., vol. v, pt. 1, 1890, p. 85; taken from Mr. Smith’s
drawings. Figs. 1 and 2, two sketches showing sculpture and variation
in form (enlarged). Fig. 8, dorsal view (natural size), accessory plate
removed. Fig. 4, interior, showing hinge characters, etc.
On December 28th last I found on the beach at Hove, Sussex,
a small block of chalk, evidently bored by Pholas, and cut from it
three specimens, two small and one larger (of which one valve was
unfortunately broken). I at once recognized these as similar to the
species in my grandmother’s collection. I searched fer several days
on the same beach and found many blocks of chalk and shale, con-
taining numerous specimens of P. parva and some other shells, but
P. candida was not represented, nor could I find any further
specimens of P. costulata.
62 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
Pholas costulata differs from P. candida in the more convex ventral
margin; in the less evenly rounded anterior end, which is more
inclined to become angular; in the more attenuated and more widely
gaping posterior end; and in the greater thickening of the shell on
the dorsal margin by the base of the internal tooth or myophore; as
well as in the external ribbing, as pointed out by Dr. Goodall.
IT am not greatly concerned with the question whether conchologists
will accept the name costulata, Goodall, as representing a species
truly distinct from candida, but I have seen no intermediate forms,
and should at once recognize any similar specimens. My personal
interest in the subject is specially due to the unexpected coincidence
that again connects it with my family. It is somewhat remarkable
that a grandson, at the age of 72, should practically rediscover
a British shell known to his grandmother as a new species in 1820,
which has escaped recognition and publication from that time to this,
except in the paper above mentioned.
P.S.—On the 6th of October, 1916, I spent several hours in
searching for more specimens of Pholas costulata. Failing to find it
on the beach where I had first met with it, I visited the coast
between Black Rock and Rottingdean to the east of Brighton.
Beneath the cliffs, at low tide, many acres of broken chalk-beds are
exposed, and these are plentifully bored by Pholas. P. parva was in
great abundance, solid and detached blocks of chalk containing many
examples; in the latter case no living specimens were found.
P. candida also occurred, but quite sparingly. I was unable to
discover a single specimen of P. costulata, and am inclined to think
that those found at Hove must have come from some other, submarine
bed of chalk, rather than from that underlying the cliffs toward
Rottingdean.

NOTE ON SOME HOLOCENE MARINE SHELLS FROM THE
ARAN ISLES, CO. GALWAY.
By J. R. rz B. Tomutn, M.A., F.E.S.
Read 14th April, 1916.
Mr. Kennarp sent me, some little time ago, a sample of blown sand
of Holocene age which he had received from Mr. R. A. Phillips, of
Cork. ‘The latter writes that he collected it from a low-lying, sandy
marsh at Killeany Bay, Inishmore, Aran Isles, Galway, where there
was blown sand covered with grass, and the material was actually
obtained from a pit excavated by the wind in this ground.
For convenience of reference the names are given according to
the last Conchological Society’s list (Journ. Conch., vol. x, 1901,
pp. 10-26). ‘The remains of bivalves are in such fragmentary
condition that it is only possible to identify them in one or two
eases. The following is the list of species :—

NOTE ON THE ERATO GUTTULA OF SOWERBY AND ON
MARGINELLA SCHEHEPMANI, N.N. FOR M. ABYSSICOLA,
SCHEPMAN.
By J. R. 1s Bavomrm, MA.,, FBS:
Read 9th June, 1916.
I. Erato eurruta, Sowerby.
Sowersy’s Erato guttula' was correctly referred to the genus
Marginella by Weinkauff,* but he is wrong in suggesting its identity
with JL. oster?, Jouss., or IL. serrata, Gask. Smith?® correctly unites
it with J/. triplicata, Gask. Sowerby’s figure is all but unmistakable,
and quite lately I found an interesting confirmation of Smith’s
verdict on an old tablet from Dr. Gray’s collection in one of the
British Museum drawers, marked ‘‘ Ilarginella guttula, Sowerby, Isle
of France”’, and bearing examples of the shell we generally know as
M. triplicata, Gask. For the future the species must be called
M. guttula, Sow., since this name is twelve years earlier than
Gaskoin’s.
This change invalidates JZ. guttula, Reeve (1865), which I regard
as a perfectly distinct species, and not a variety of JL. avena, Kiener,
as indicated by Tryon and others. I propose, therefore, to rename it
M. pericalles. Very beautiful living specimens of it were collected in
Bermuda by Colonel Peile.
Il. Mareinerta asysstcora, Schepman.
This species is Gescribed in the Prosobranchia of the Siboga Expedi-
tion, pt. iv, p. 260, pl. xviii, fig. 8 (September, 1911), from a single
example dredged in the Banda Sea. Locard,* however, described
a Gibberula abyssicola in 1897 from the Travailleur and Talisman
Expedition, and since Gibderula is, in my opinion, a division of very
shght importance, and certainly not of generic value, I propose. to
call the Siboga shell Jarginella schepmani, after the painstaking
author of the monograph.

Read 14th April, 1916.
Genus LANISTES, Montfort, 1810.
THe genus Lanistes embraces all the sinistral species of the family,!
and I see no valid reason for separating J/eladomus (Swainson) from
it; still less can I agree with Bourguignat in dropping the name
Lanistes in favour of Meladomus. Bourguignat gives as his reason
that the prior name was used by Humphrey (Musewm Calonnianum,
1797) for a species of Mytilus, but it has been very properly decided
that these mere catalogue names should have no status as to priority.
Moreover, my copy of the Mus. Calonn. makes no mention of
“« Lanistes”’, but ‘‘ Lanatus”’ stands for a variety of Mytilus discors.
The genus Leroya, Grandidier (Bull. Soc. Malac. France, iv, 1887,
p- 185), 1 place as a sub-genus having spiral sculpturation.
In compiling the following list of species and synonyms I have
been compelled, after comparing numerous examples, to place in the
synonymy many names that have generally been accepted as applied
to valid species. ‘There are others of which I have not seen sufficient
numbers to enable me to decide whether they are good species or
not; these I have allowed provisionally to stand.

' The more or less depressed examples cannot be definitely
separated from the typical form.
‘ The only sinistral Ampullaria of which I have heard is a ‘‘ subvar.
sinistrorsa’’? of A. globosa, described by Nevill in the Indian Museum,
Calcutta, which is probably unique (Hand List Moll. Ind. Mus., pt. ii,

DESCRIPTIONS OF SEVEN NEW SPECIES OF MOLLUSCA
BELONGING TO THE GENERA DRILLIA, CLAVATULA,
HPITONIUM, CANTHARIDUS, BITTIUM, FISSURELLA, AND
CARDIUM.
By G. 3B. Sowrrsy, F.L.S.
Read 12th May, 1916.
PLATE Ih ies: 1-8:
1. Dents CARMEN, nesp. (Pl. VET) Fis.52;
Testa fusiformis, fulvo-albida, fusco pauci-maculata ; antice breviter
rostrata, postice elato-turrita; spira elongata, acuta; anfractus 84,
primi 2 leves, nitentes, leviter obiique contorti, cateri convexi,
spiraliter regulariter filo-lirati, longitudinaliter crassi-plicati, plicis
rotundatis, obtuse angulatis, interstitiis pallide fusco maculatis;
sutura leviter impressa; anfractus ultimus + longitudinis teste
gquans, supra obtuse angulatus, deinde leviter convexus, infra
medium contractus et attenuatus; apertura oblonga, canalis productus,
latiusculus; columella rectiuscula, antice producta; labrum acutum,
sinu postico latiusculo. Long. 18, maj. diam. 8 mm.
Hab.—Goto, Hizen, Japan (Hirase).
A typical Drillia, with somewhat angular whorls, and numerous
rounded longitudinal plice ; finely spirally lirate throughout. The
plicee are rendered conspicuous by the light-brown colouring of the
interstices. Perhaps the nearest species is D. griffithi, from which it
may be readily distinguished by its much more delicate sculpture.
2. CLAvaTuLA DEcoRATA, n.sp. Pl. III, Fig. 1.
Testa fusiformis, tenuis, fulvo-fusca ; spira acute turrita, elata;
anfractus 19, concavi, leves, inferne carina conspicua albo anguste
zonata multi-tuberculata et fusco interruptim unilineata ornata ;
sutura sulcata, infra carina levis angusta marginata; anfractus
ultimus +4 longitudinis testa eequans, supra valde concavus, ad
peripheriam carina tuberculata per-prominens instructus (tuberculis
albis oblique verticalis) infra angulum anguste spiraliter grano-liratus,
deinde contractus et rostratus; apertura mediocriter lata, canalis
longus ; labrum tenue, postice late et profunde sinuatum. Long. 21,
diam. 8 mm.
I have only seen a single individual of this species. It was found
in the collection of the late Admiral Keppel without any indication
of its habitat, but comes very likely from Sierra Leone, where the
Admiral collected largely.
The shell is one of striking character, the whorls being unusually
concave, with a stout prominent keel, crossed by numerous oblong
somewhat oblique white tubercles or short plice, which are rendered
more conspicuous by a brown intersecting spiral line.
3. Epirontum rEYNoLDSI, n.sp. Pl. III, Fig. 4.
Testa imperforata, angusta pyramidata, solidiuscula, fusco-grisea,
albo-balteata; spira turrita, acuta; anfractus 10, rotundati, obscurissime

hic illic plusminusve crassis muniti; sutura angusta; anfractus
ultimus + longitudinis teste sequans, fusco bizonatus, albo late
balteatus; apertura fere circularis; peristoma crassum, album.
Long. 18, maj. diam. 7 mm.
Hab.—F lorida (Reynolds).
This species, of which I have only seen a single specimen, was
sent by Mr. Reynolds, of Florida. It differs considerably from any
ofits congeners. Its surface is rendered slightly rugose by very faint
eancellating striz, and its varices are for the most part thin, and
very slightly raised; but at distant intervals there are a few much
stouter ones.
I have been at variance with several eminent conchologists con-
cerning the substitution of the name Scala for Scalaria (see Ann.
Mag. Nat. Hist., November, 1903). I am now glad that the
question is settled by discarding both these names in favour of
Epitonium, Bolton (1798), which has priority.
4, CanrHaRipUs RARIGUTTATUS, n.sp. PI. III, Fig. 8,
Testa conica, profunde umbilicata, fusca, hic illic sparsim albo
maculata et flammulata; spira elata, lateribus leviter convexis ;
anfractus 5, convexiusculi, liris numerosis confertis leviter elevatis
spiraliter cingulati, oblique tenuissime striati; sutura anguste
canaliculata; anfractus ultimus % longitudinis teste equans, ad
peripheriam obtuse angulatus, ad basim convexus, umbilicus excavatus,
intus rotundus, profundus; apertura subquadrata, intus iridescens ;
columella crassa, albida rectiuscula; peristoma simplex, tenue.
Long. 12, diam. 10 mm.
Hab.—New Caledonia.
A shell having the prevailing form of a Cantharidus. It is dark
brown in colour, with here and there a few whitish spots and streaks,
spirally closely lirate, iridescent within. I have seen ten specimens
varying very little in form, but some of them are almost, or quite,
destitute of the whitish markings mentioned.
5. Brrrium perspicuum, n.sp. Pl. III, Fig. 3.
Testa elongata, angusta, tenuis, imperforata, fusca, varicibus per-
conspicuis albis distantibus munita; spira elongata ad apicem
angustissima ; anfractus 12, leviter convexi, spiraliter dense et rugose
lirati, sutura valde impressa sejuncti; anfractus ultimus brevis,
brevissime rostratus; apertura subquadrata, brevis; peristoma
simplex, tenue. Long. 6, diam. 2 mm.
Hab.—Trincomalee, Ceylon.
This species is chiefly distinguished by its prominent, irregularly
distant, short, white varices.
6. Fissunetta (Gryprus) sacax, n.sp. Pl. III, Figs. 5, 6.
Testa ovalis, mediocriter lata, elata, luteola, costis radiantibus
creberrimis leviter nodulosis, et liris concentrices irregularibus

mucronata; foramen parvum, oblongum, leviter constrictum, multo
antimedium situm; pagina interna alba, supra callo denticulata
induta, ad marginem crenulata. Long. 8, lat. 7, alt. 5 mm.
Hab.—New Caledonia.
Of this curious little species I have only seen four specimens, two
quite young and two apparently adult. The adult are peculiarly
swollen on the back, and in both young and old the border of the
foramen is curiously mucronate.
7. Carpium FuLronr, n.sp. Pl. III, Fig. 7.
Testa oblique subovalis, crassiuscula, leviter inflata, alba, maculis
numerosis vivide rufo-fuscis pulcherrime ornata, radiatim costata;
costis circiter 27 prominentibus, valde nodosis; interstitiis profundis,
transversim sulcatis; umbones mediocriter elevati, latiusculi.
Umbono-marg. 37, antero-post. 33 mm.
Hab.—Philippines.
A pretty shell, ornamented with red-brown spots on a white
ground. The ribs are rather peculiarly knotted, especially on the
anterior side. The form and general aspect of the shell are somewhat
similar to that of a recent Zrigonia. I have only seen a single
example of this species.

NOTES ON A SMALL COLLECTION OF HELICOID LAND SHELLS
FROM THE SHOUTEN ISLANDS, DUTCH NEW GUINEA, WITH
DESCRIPTIONS OF TWO NEW SPECIES OF PAPUINA.
By Huenw C. Forron.
Read 14th April, 1916.
PLATE III, Fies. 9-14.
Te shells here noted were collected by Mr. Pratt on the Island of
Wiak and a smaller unnamed island to the south-east of it.
1. Xesta avtica, Pfr. Wiak I.
A number of examples of this species were obtained, most of them
being the usual colour varieties, but two are new to me; one has the
apical whorls white, whilst the lower whorls are covered with a very
light uniform greenish-yellow periostracum ; the other shows various
shades of brown from reddish to a dark smoky brown; both varieties
have the usual darker-coloured spiral band and are not polished,
but exhibit a duller surface than is usual in this protean species.
2. Xesra FRAUDULENTA, Smith. Wiak I.
In addition to the typical form one or two specimens were collected
that have a narrow spiral band of darker colour situate just above the
periphery of the last whorl and continued upwards towards the spire.
3. XESTA PORCELLANICA, Sarasin. S.E. of Wiak I.
Some specimens are of a uniform whitish coloration; others have
a narrow reddish-brown band at the suture, which is continued to
about the first half of the last whorl.
4. Cutoriris crrcumpata, Fér. Wiak I.
5. Cutoriris (ALBEersra) zonuLaTa, Fér, Wak I.
6. Papurna HERO, Smith. S.E. of Wiak I.
Very large examples of this handsome species; the type is smaller,
but not so small as some specimens that were collected on a former
expedition by Mr. Pratt at Muswar I., Geelvink Bay; the species
evidently varies greatly in size.
7. Pavurna TRocuiForMis, Preston. Wiak I.
wo specimens, both of which have a somewhat higher spire than
the type, but agree well with it in other respects.
8. Papuina suscosrata, n.sp. Pl. III, Figs. 12-14.
Shell depressed trochoid, moderately solid, openly umbilicated to
a width of about 4 mm., light brown with a rather broad band of
darker brown encircling the last whorl, situated just above the middle
and continued upwards for a short distance at the suture of the
78 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
penultimate whorl, the last two whorls have a whitish thread-like
line at the suture, upper part of shell finely obliquely striated, on
the lower two whorls the strize gradually become stronger until the
last half-whorl has the appearance of being broadly but obtusely
costate, the whole surface of the lower whorls is covered with a
microscopic granulation ; whorls 53, slightly convex, the last rounded
but showing some indications of a keel; aperture transversely oval,
whitish within, the outer band showing through; peristome white,
very oblique, broadly expanded and somewhat reflexed, margins
joined by a thin transparent callus.
Maj. diam. 36, alt. 22mm.
Hab.—Wiak I.
Allied to the Papuina labium-lituus-multisona-wallaceana-aurora
group (all of which may prove to be but varying forms of one species),
but our new species can be easily distinguished from all by its open
umbilicus and the coarse oblique sculpture of the last whorl. The
specimen selected for the type is of a light yellowish-brown with a
rather broad dark-brown band at the periphery of the last whorl; but
there are also specimens of a uniform dark brown without any band,
and other examples have the last whorl dark brown, whilst the upper
whorls exhibit a lighter-brown coloration. All have the characteristic
open umbilicus and coarse sculpture.
9. Papurna mEpipa, n.sp. Pl. III, Figs. 9-11.
Shell depressed trochiform, rather thin and transparent, openly
umbilicated to width of about 3mm., of a very light yellowish-brown
colour; whorls 5, distinctly convex, with very fine oblique striz or
lines of growth, lower whorls covered with microscopic waved
granules, last half-whorl is bluntly whilst the first half is sharply
carinate, there is a spiral white thread at the suture of the
penultimate which is continued half-way round last whorl, where it
is covered by a narrow reddish-brown band which extends to the
peristome; aperture transversely oval, whitish within; peristome
expanded and slightly reflexed, flesh-coloured.
Maj. diam. 29, alt. 17 mm.
Hab.—Wiak I.
Approaching but quite distinct from P. pseudolanceolata, Dtz., and
P. callosa, Sykes, from both of which it is easily distinguished by its
open umbilicus and much less angular peristome.

ON TWO EDITIONS OF DUMERIL’S ZOOLOGIE ANALYTIQUE.
By Tom Inepatr.
Read 14th April, 1916.
I wave only seen one reference to this work, namely that in the
Nautilus, vol. xv, p. 127, March, 1902, where Dr. W. H. Dall wrote
as follows: ‘‘I have frequently called attention to the ill-effects of
the absurd European proposition that names such as Cyprinus and
Cyprina should not be allowed to exist in nomenclature simultaneously
Finding the name Jassaria challenged on this ground, I hunted
up the earlier use (1806) in Duméril’s Zoologie Analytique, and took
the occasion to make a full list of Duméril’s names, which all end in
-arius and are all synonyms. Some appear in the text, and others in
the Latin index only, with references to the pages where the French
equivalent is to be found. Among the latter I discovered Pleuro-
tomarius, Duméril’s name for Pleurotoma. If the idiotic rule above-
mentioned was put in force this superfluous synonym would deprive
us of the right to use Plewrotomaria, J. Sowerby, which dates only
from 1821, and perhaps also Plewrotomarium, Blainville, another
rendering of Defrance’s French name which dates from 1825. I may
add that any rule admitting anonymous names, taken into con-
sideration with the above-mentioned one, would upset about half of
the best-known names in mollusean zoology, including such as Oliva,
Cyprea, ete.”
The last sentence seems to have been written in a hurry, asCyprea
is a Linnean 1758 name, and as far as I can judge absolutely
unassailable, while I have no record of any danger to Oliva from
either of the causes Dr. Dall has quoted.
In the above-mentioned quotation Dall does not discuss the validity
of Duméril’s names, but apparently accepts them as valid. Many of
them were quoted in synonymy by the Adams Bros. in their
Genera of Recent Mollusca. Scudder also records most, if not all,
of the names. Consequently they have been available to workers
for many years, and there is no new discovery here. It seems necessary
to make this statement in view of the results hereafter given. Dall
afterwards reconsidered the matter of rejecting Duméril’s nomen-
clature as not acceptable, for in the U.S. Geol. Survey Prof. Paper
No. 59, 1909, p. 46, in the synonymy of Zhais, Bolten, he wrote:
‘* Purpurarius, Duméril, Zool. Anal., p. 166, 1806: nomenclature not
Linnean: Froriep’s German transl., p. 167 (P. persica cited), 1806.”
I cannot accept the dictum that Duméril’s ‘‘nomenclature”’ is ‘‘ not
Linnean”. This wonld certainly have been an easy solution to the
problem, but unfortunately it is not maintained in other branches of
Zoology. Thus, in Ornithology, the names proposed, when available,
by Duméril are in use. I believe also that Ichthyologists utilize
Duméril’s novelties without question. My own method of dealing
with Duméril’s names would be to advise rejection whenever there is
the slightest technical cause and to urge the strict letter of the law
80 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
against them, but where no cause can be shown for rejection to at
once make use of them, and so rid ourselves of an annoying shadow
in our nomenclature.
The title of Duméril’s book is ‘‘Zoologie Analytique, | ou | Méthode
Naturelle | de | Classification des Animaux, | rendue plus facile | a
Vaide de tableaux synoptiques; | Par A . M. Constant Dumeéril, |
Docteur en médecine, .. . | Parva sed apta. | Paris, | Allais, Libraire,
Quai des Augustins, No. 39, | M,pccc,vr”’.
The dedication to ‘‘ Monsieur de La Cépéde ” is dated ‘‘ Ecija, le
20 septembre, 1805”’’, the preface ‘‘Cordoune, le 17 septembre, 1805”’.
In this preface Duméril, p. xxiii, wrote: ‘‘La classe des mollusques
offrira des ordres tout-d-fait nouveaux; mais ils ont été faits ou
indiqués, déja par M. Cuvier lui-méme, qui a le premier séparé ces
étres de la classe nombreuse des vers de Linné. ‘lous les savans ont
adopté maintenant cette classification ; et comme notre objet étoit de
faire connoitre les animaux et non les coquilles qui les revétent, nous
n’avons profité que dans trés-peu de circonstances des travaux de
MM. Poli et Lamarck, cette partie de la science laissant encore
beaucoup a desirer aux naturalistes.”’
The Cuvierian work referred to is designated on the previous page
as the ‘‘ Tableau élémentaire de lHistoire naturelle des Animaux”’.
I therefore conclude that the above can be considered as a direct
bibliographical reference, basing my conclusion on the opinion
(No. 39) given by the International Commission on Zoological
Nomenclature, when dealing with a very similar case. his decision
is not in accord with that given by Dr. Dall, already quoted, but in
view of the complication hereafter exposed I suggest reconsideration,
and moreover confidently anticipate agreement with the results
advocated in this note.
The complication consists of the German translation, which was
quoted by Dall without comment, but which necessitates a recon-
sideration of the whole matter. The title-page reads: ‘‘C. Duméril’s, |
Doctors und Professors an der Medicinischen Schule | zu Paris, |
Analytische Zoologie. | Ausdem Franzosischen, | Mit Zusitzen | von
| L. F. Froriep, | Professor zu Halle. | Parva sed apta. | Weimar | Im
Verlage des Landes-Industrie-Comptoirs | 1806.”
Froriep’s ‘‘ Vorrede”’ is dated ‘‘ Halle am 18 Sept. 1806”, and in
it he explains that as no examples are given in the original he has
added to each genus-name a species cited from Gmelin’s edition of
Linné’s Systema Nature.
Let us now consider the original edition and its effect on the
accepted nomenclature of Mollusca. The names collated by me as
new are as follows :—
p- 156. Argonautarius, new name for Argonauta, Cuv.
Nautarius Nautilus, Cuv.
p. 157, Sprrularius Spirula, Lam.
p- 162. Patellarius Patella, Cuv.

Naticarius Natica, Lam.
Neritarius Nerita, Cuv.
Monodontar ius Monodonta, Lam.
Valvearius Valrata, Miller.
Scalatarius Scalaria, Lam.
p- 166. Conarvus Conus, Cuv.
Cypriarvus Cyprea, Cuv.
Olivarius Oliva, Cuv.
Volutarius Voluta, Cuv.
Nassarvus Nassa, Lam.
Purpurarius Purpura, Brug.
Buceinarvus Buceinum, Cuy.
Terebrarius Terebra, Lam.
Murieiarvus Murex, Cuv.
Turbinellarius Turbinella, Lam.
p. 168. Venusarius Venus, Cuv.
Solenarius Solen, Cuv.
Myarius Mya, Cuv.
Ostracarius Ostrea, Cuv.
In the Latin Index I find several which do not appear in the text
save in the vernacular form, and these can only be linked up by the
pagination ; such are:
p-. 834. Colombellarius, new name for Columbella, Lam.
p. 838. Marginellarius Marginella, Lam.
p- 340. Pleurotomarius Pleurotoma, Lam.
p- 840. Pholadiarius Pholas, Cuv.
p- 385. Donaciarius Donax, Lam.
p- 843. Zellinarius Tellina, Cuv.
Teredarius Teredo, Cuv.
p. 333. Cardiarius Cardium, Cuv.
p- 386. Haliotidarius Halyotis, Cuv.
p. 840. Pinnarius Pinna, Cuv.
It will be just as well to cite an example of Duméril’s method,
since it is not a common book. I quote part of Table No. 105
(p. 167). This covers his ‘‘ [[1¢ Famille. Siphonobranches ”’, and the
diagnosis reads ‘‘ Mollusques gastéropodes testacés a deux tentacules,
& coquille échancrée ou prolongée en un canal pour recevoir un siphon
propre a la respiration”. Thirteen genera are admitted with
vernacular names only, differential diagnoses being prepared. Thus
the two main sections are ‘‘Opereule distincte’’? and ‘‘Opercule
nulle”; the former is then subdivided thus: ‘‘ a yeux a la base des
tentacules”’ and ‘‘a yeux non & la base des tentacules”’, and so on.
On the opposite page (166) ‘‘ Notes sur le No. 105” are given, and
equivalent to most of the vernacular names Latin ones are allotted in
brackets, thus: ‘‘ Les nassiers (nassarius).” A few read as follows
(p. 166): ‘‘ Les turbinelliers (turbinellarius) et les pleurotomiers ...”
No equivalent is given to the last-named, but in the Index (p. 340)
82 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
the word ‘pleurotomarius’ appears and p. 166 is added. From
Duméril’s usage it can be deduced that these are connected, but
strictly speaking I would have regarded tle index names as nomina
nuda, and objected to their active incorporation into molluscan
nomenclature. Three bibliographical references are given by Duméril
—first to Cuvier’s Zableau Hlém., second to Poli, and third to Lamarck.
Consequently Duméril’s names all depend on these works. I therefore
allot all I can first to Cuvier’s work, then to Poli’s, and lastly to
Lamarck’s as synonyms. Cuvier’s names are simply those of Linné,
so that Duméril’s names follow the Linnean ones and are absolute
synonyms of those. None are referable as new to Poli, so that the
only names that interest us are the emendations of the Lamarckian
names. Most interest ‘centres around
NaAssAnRius.
This can only be determined as a new name for Wassa, Lamarck,
1799, non Bolten, 1798. ‘he type of Massa, Lam., is Buecinum
mutabile, Linn. Recently Lamarck’s familiar name has been
rejected, as it was antedated by Bolten’s usage in another con-
nexion. As substitutes Now
reference is given, since Martyn’s second volume had not been
published at this date.¥

In this connexion may be noted that the Catalogue was published
between the 8th and the 24th of April, 1786, and we do not know
the exact date of publication of Martyn’s vol. ii, save 1786. ‘This
suggests that if the Portland Catalogue’s valid names clashed with
Martyn’s the former should have priority. I know of one case,
Patella umbraculum, and I will use this name in preference to
Martyn’s (Lepas) umbella, until such time as an exact date is known
for the latter, when the matter may be reconsidered.
The valid names are as follows :—
Arca fusca, 8., p. 42, based on Gualt., 87 G.
labiata, S., p. 185 D’ Avila, vol. i, pl. 18.

I had hoped to have given the exact status of each of the above
names, but my ignorance of general conchology has compelled me to
forego that idea.
I believe, however, that the preceding list will
prove useful, and here add a few notes whereby the work of my
eritics may be lessened.
Page 186, lot 3964, reads: ‘‘ A very fine specimen of the Concho-
Lepas, or Cockle Limpet.
Humph. Conch. page 12, No. 7, plate 4,
fig. 9, which was taken from the shell. See also Favanne, pl. 4,
fig. H. 2, from the Straits of Magellan.”
I note that the following Solander names are invalid through
earlier usage of the same combination, mayhap in some cases in the
same connexion. ‘The necessary data can be easily recovered in each
instance from the same source as I have consulted, viz. Sherborn’s
Index Animalium. Such are Serpula gigantea, Buceinum monodon,
Trochus solaris, Arca nodulosa, Voluta muricata, Mytilus pictus, Helix
picta, and H. plicata.
A second series of invalid names are those proposed for the shells
figured by Martyn in the first volume of the Universal Conchologist.
These are Buccinum iris, Voluta elongata, V. filosa, Trochus solaris,
V. incompta, Murex fimbriatus, and T. sulcatus. I have compiled
from Sherborn’s Jndex a third list of names, these being generally
referred to a later worker. The latter need investigation, though in
some instances probably they refer to the same species, viz.: Arca
92 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.

1792; OC. leoninus, Gmelin, 1791; C. nocturnus, Brug., 1792;
C. quercinus, Brug., 1792; C. sulcatus, Brug., 1792; Cymbium melo,
Bolten, 1798; Cyprea nebulosa, Gmelin, 1791; Helix undata, Gmelin,

Voluta arausiaca, Shaw, 1790; and V. seapha, Gmelin, 1791.
Most, if not all, of these Solander names are quoted by Dillwyn in
his synonymy, but I have refrained from citing Dillwyn’s equivalents
as it is commonly known that these may not be exact, and I might
only cause confusion. Thus Area fusca of Solander is cited as
a synonym of Arca imbricata, Bruguiere, over which it has priority,
while it invalidates the later Arca fusca, Bruguiére. The exact
determination of the correct names of the two species concerned
would need special knowledge, for E. A. Smith has shown that
Lamy’s synonymy of these complex bivalves is open to correction.
Srromsus Livipus, Linné.
Hedley, in the Proe. Linn. Soc. N.S.W., 1909, vol. xxxiv, p. 453,
used Drillia livida ex Gmelin, explaining: ‘‘In the absence of
a figure and a type, the Linnean Strombus lividus is, according to
Hanley, unrecognizable. Under these circumstances it is better to
adopt the name of Gmelin, securely based on the figure of Chemnitz
(Conch. Cab., ix, 1786, pl. 186, f. 1269-70), than to use Lamarck’s
aurieulifera.”
I have made it a rule never to accept second-hand determinations,
so that to me Linné’s species being indeterminable Gmelin’s inter-
pretation did not systematically concern me, save as a synonym.
For the shell figured by Chemnitz, Bolten (prior to Lamarck) had
proposed two names, viz., (Mus. Boltenianum, p. 100) S| ¢rombus |
canalicularis, and (p. 124) 7[urris] St. Stephani. I should therefore
have preferred the safe method of nomination and called the shell
“ Drillia”’ canalicularis (Bolten). The sequel appears in the present
publication, as on p. 91 we read, ‘‘ A pair of large and fine Strombus
lividus, L., from Guinea, Lister, 121, 17, rare.’ Here we have
a definite and earlier attempt to fix the Linnean species, and,
moreover, one more valuable than Gmelin’s, as Solander was a personal
pupil of Linné and more likely to know the Linnean shell. I cite
this as of interest in confirming my proposed usage of the Boltenian
species-name, and not as an incentive to use Solander’s acceptance of
the Linnean name.
I have cited ‘‘ Driilia”’ as I do not consider this genus-name in any
way satisfactory. It is restricted to the species D. umbilicata, Gray,
fixed as type in 1847, and I cannot trace any knowledge of the animal
of this apparently aberrant species. It belongs to the west coast
of Africa, where also Clavatula typical is found, and the shell
characters of this genus, as commonly utilized, approach so closely
that it is difficult to separate these genera. I do not believe the
Pacific ‘‘ Drillia”’, especially the smaller species, are closely related.
IREDALE: SOLANDER AS A CONCHOLOGIST. 93.
Cyprm#a umBiticata, Solander.
On p. 65 ‘* Lot 1471, Cyprea umbilicata, 8., Coromandel” occurs.
Here it is a nomen nudum.
Dillwyn, in his Index Hist. Conch. List., 1823, p. 32, gives
a note identifying List., 667, fig. 12, thus: ‘‘ This shell has been
arranged as a variety of Cyprea Pyrum, and as a separate species in
Solander’s MS. with the name of Cyprea umbilicata; it has the teeth
of a saffron colour, and in Cyprea Pyrum they are whitish.’ This
quotation validates Cyprea umbilicata as of Dillwyn, 1823, and
invalidates Cyprea umbilicata of Sowerby, 1825. Recently Verco
has given a good history of the latter species, and now his varietal
name armeniaca will become the species-name, while the typical
form will need renomination. In order to draw attention to this
matter I propose to rename C. umbilicata, Sowerby, and to eall it
CYPR#A HESITATA.
[P.S.—Murex fimbriatus of Solander (ante, p. 90) unfortunately
invalidates Murex fimbriatus of Lamarck, 1822, which has just
recently been rehabilitated, after ninety years, by C. Hedley (Proce.
Linn. Soc. New 8. Wales, vol. xxxvili, 1913, p. 328). |]

I. Hisrortcat Notes.
It seems meet to anticipate the systematic correction of some
misnamed Tasmanian Chitons with a few notes which may appear
outside the scope of our title, but which nevertheless are the direct
results of research conducted with the above sole aim.
The earliest collectors of Tasmanian Chitons appear to have been
the famous French naturalists Péron and Lesueur. In 1802 the
Géographe called at southern Tasmania, and Péron records that he
met with wonderful shells on Maria Island. Our friend Mr. Chas,
Hedley has sympathetically related (Proc. Linn. Soc. N.S. Wales,
vol. xxxix, 1915, p. 727) how a comrade, Mauge, perhaps even
keener than the two above-named naturalists, passed away through
an effort to participate in the spoils, and was buried on the island.
We have no record of any Chitons preserved from this particular
locality, but it may be that Mauge’s eyes feasted upon the
species with which we associate his name. The following year
the Géographe returned from Port Jackson and stayed at King
Island, Bass’ Straits, where a large collection of shells was made.
IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 95
Péron was now the conchologist of the trip, but unfortunately,
though he survived to reach Paris with his treasures, science was
deprived of his personal experiences and knowledge by his early
decease. Lesueur was primarily the artist, and though he edited his
friend’s journal he did not attempt to deal with this collection, which
was deposited in the Paris Museum. Blainville, however, in the
preparation of the pioneer monograph of this group published in the
Dict. Sci. Nat., vol. xxxvi, 1824, made good use of the material, and
many species were described as collected by Péron and Lesueur from
various Australian localities. The only definite citations are from
King Island and King George’s Sound, but unfortunately, through
accidents, Péron’s collections had suffered so that incorrect data were
frequently ascribed to the specimens, and the correction of such
errors has been made with great difficulty, as hereafter shown.
Quoy and Gaimard, twenty years after Péron and Lesueur, collected
in southern Tasmania, and their great interest in this group is
manifested in their beautiful plates and lucid descriptions.
The earliest British visitor who was a collector of Chitons appears
to have been Dr. Sinclair, R.N., but his discoveries are peculiarly
perplexing, since his shells also appear to have been mixed and we
have had a great deal of trouble in clearing these up. ‘Thus, in
Dieffenbach’s Travels in New Zealand, vol. ii, 1843, Gray described
some New Zealand forms and enumerated the New Zealand molluscs.
On p. 245 he recorded :—
Acanthopleura undulatus; Chiton undulatus, Q. & G., New Zealand,
Van Diemen’s Land, Dr. Sinclair, R.N.,
and p. 262 :—
Acanthochetes hookeri, u.sp., New Zealand, Van Diemen’s Land,
Dr. Sinclair, R.N.
A few years later Reeve in the Conch. Icon., section Chiton,
included the following species as collected by Dr. Sinclair in Van
Diemen’s Land, viz.: Chiton sinclairi, Mus. Cuming, C. inguinatus,
Mus. Brit., and C. carinulatus, Mus. Brit.
None of these records is reliable. The first three are undoubtedly
Neozelanic, the fourth is probably so, and the last may be West
American.
Reeve at the same time described Chitonellus gunnii from specimens
forwarded by Roland Gunn, which appears to be the only contribution
made to our study by that famous Tasmanian naturalist.
Joseph Milligan’s name is known in this connexion through the
record of some species from Flinders Island by E. A. Smith in 1884.
The true facts have never been published, but it would seem that we
must consider Milligan to be the first native Chiton enthusiast, for
reterence to the British Museum Registers and collections shows the
following items: In the year 1850 Joseph Milligan presented to that
institution a series of Tasmanian shells, including Chitons collected
on Flinders Island, Bass’ Straits. The Chitons were forty-seven in
number, separated by Milligan into nineteen lots. This series has
been traced in the British Museum, and we find it covers the
96 FPROCERDINGS OF THE MALACOLOGICAL SOCIETY,
majority of the forms recently collected by one of us on the
Furneaux Group. Thus, ave note “Jschnochiton ecrispus, ustulatus,
contractus, deeussatus, cariosus, maytt, australis, novehollandia,
Cryptoplaxe gunnii, Notoplax speciosa, Acanthochiton asbestotdes, and
Loriea volvo”. We have quoted these names as being in use, but
we show many to be incorrect hereafter. The collection was
simply placed in the drawers in the British Museum without study,
but thirty-four years afterwards E. A. Smith recorded a couple of
species and described one new one from Milligan’s gift. One of us
recorded only three years ago, and sixty-three years after Milligan’s
discoveries, three of the above-named species as new to Tasmania,
This tardy recognition of Milligan’s suecess in Chiton-collecting is
noteworthy, since we can now accept this worker as our earliest local
predecessor,
The earliest list we recollect is that of Tenison-Woods in 1877,
when eleven species were included, but Woods conservatively
estimated this as far too many. We wonder how he would greet
our fifty to sixty species and suggestions of many more. We have
not with certainty determined the modern equivalents of his
eleven names,
Tate and May in 1901, mainly from collections made by the latter,
were enabled to recognize twenty-four species, but these included
some doubtful forms.
Torr, the most diligent Chiton collector in Australasia, explored
the north-west coast, and as a result a new list was drawn up.
This was published in the “ Papers and Proe. Roy. Soc. Tasm.”’ for
1912, pp. 25-40, by May and Torr, as follows :—
Lepidopleurus inquinaius (Reeve). Dredged 15 f. and 9 f., South-east
Coast.
matthewstanus, Bednall. One specimen, North-west Coast.
columnarius, Hedley & May. One specimen, 100 f., South Coast.
Callochiton platessa (Gould). North Coast.

IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 97
Acanthochites speciosus (H.Adams). Dredged 9f., South-east Coast.
lachrymosus, May & ‘Torr. South-east Geek:
Cryptoplax striatus, var. gunnit, Kast and North-west Coasts.
Reeve.
Chiton gugosus, Gould. North-west, South, and East Coasts.
pellis-serpentis, Quoy &Gaimard, Universal.
tricostalis, Pilsbry. North Coast.
quoyt, Deshayes. South-east Coast.
calliozona, Pilsbry. One valve only.
Loricella angasi (Adams & Angas). North-west Coast.
Liolophura gaimardi, Blainville. Recorded but doubtful.
The following species admitted in the Revised Census in 1901 were
rejected, as not rediscovered or authenticated :—
Ischnochiton fruticosus (Gould), |New South Wales.
carinulatus (Reeve). Described from ‘ Tasmania ”’
tateanus, Bednall, South Australia.
Acanthochites granostriatus, Pilsbry. = A. bednall, Pilsbry.
costatus, Adams & Angas.
An investigation of the Furneaux Group enabled one of us to
add some more species, whilst also other shells found there incited
a redetermination of some species, and these specimens were
forwarded to England for comparison with the British Museum
types, hence the present paper. ‘The species added were (Victorian
Naturalist, vol. xxx, 1918, p. 59) Ischnochiton sulcatus (Quoy and
Gaimard) = decussatus (Reeve), I. ustulatus (Reeve), and Lorica volvox
(Reeve) ; and the doubtful species were Jschnochiton cariosus, Pilsbry,
and J. contractus (Reeve).
Continued interest through the publication of these accounts
resulted in further discoveries, and in the ‘‘ Papers and Proceedings
Royal Society of ''asmania”’, 1915, pp. 78-9 and 81-2, May added
Chiton oruktus, revel C. aureomaculatus, Bednall & Matthews,
- Acanthochiton kimberi, ' Yorr, and A. rubrostratus, Torr, all from the
south-east coast, and extended the range to the south-east coasts of
Lorica volvox (Reeve), Callochiton inornatus (Ten.-Woods), C. mayt,
Torr, Acanthochites variabilis, Adams & Angas, and Callistochiton
antiquus (Reeve).
This made up a total of thirty-nine species, but the collections now
studied by us show at least sixty species.
We here record our thanks to a recent and most energetic field
naturalist, our friend Mr. Ernest Mawle, of Port Arthur, who has
submitted and presented to us splendid specimens of many species
which are worthy of special note for their perfect preservation and
large size. We have attached his name to two magnificent new
species as a mark of our appreciation of his good work, and note
that we have other new discoveries made by him now before us and
anticipate many more.
It is Pye difficult to fully express our thanks to our friend
Dr. W. G. Torr for his generosity in presenting us with so many
Tasmanian forms, the results of much labour in collection, and,
98 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
further, Iredale desires to place on record at this, the earliest,
opportunity, his gratitude to Dr. Torr for the gift of an unequalled
and complete series of South Australian shells, whereby definiteness
has been gained in connexion with typical Adelaidean forms. We
have continually referred to Torr’s papers, and, though the nomen-
clature needs revision, these mark an epoch in the study of Australian
Chitons, being based on personal experience, whilst his field notes are
very valuable.
The types of the new species will be presented to the Tasmanian
Museum, Hobart. These are undissected shells which have been
figured as such; detail figures will be later given from dissected
paratypes.
If. Sysrematic Nores.
We preface our corrections and descriptions of new species with
a few words of explanation and warning. The list given above needs
extensive revision, and we have to point out one general reason.
Many species were described by Reeve from the Cuming Collection
and British Museum. Reeve only described and figured one specimen
of each species, and very fortunately his artist painted the shell
carefully. We are thus able to trace the individual which must
be regarded as the type. When Pilsbry prepared his monograph he
was dependent upon Carpenter’s MS. notes on these shells, and
Carpenter did not differentiate this figured shell. The only worker
who has since determined Australian shells by direct comparison with
the British Museum material also overlooked this item, which now
proves important. One of us has endeavoured to fix these figured
shells, and hereafter we record some results, but we would note that
complications may yet occur.
The word of warning is in connexion with the description of new
species from unique examples of which we do not as yet know
the variation and evolution through their growth stages. Hence,
while geographically species can be easily named and thus variation
gauged, it is impossible to apply the knowledge so gained from
one species to another case even in the same genus. The growth of
sculpture and development of girdle-scales need careful investigation,
for we find that the young of some species of Jschnochiton differ
in both these items from the adult and senile phases. We have
now before us almost twenty different species represented by a few
specimens; most of these are very distinct, but we withhold
descriptions until possessed of more material that will illustrate the
growth stages. Itisalso necessary to use the microscope in connexion
with each specimen, though we have found it an infallible law that
the strange appearance of a shell is the first attraction, and that in no
case are species so alike that no superficial difference is apparent at
first sight.
1. Curron rneurnatus, Reeve.
This species was described from ‘‘ Van Dieman’s Land; Dr. Sinclair ’’.
In 1896 Sykes dissected one of the type-specimens and found it to
be a Lepidopleurus, and recorded the species from Victoria, while
IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 99
simultaneously Pilsbry and Suter added New Zealand as an additional
locality, and Bednall extended the range to South Australia. In 1910
May recorded it as dredged in 9 fathoms off Pilot Station, River
Derwent, and in 1912 May and Torr added ‘‘ large specimens dredged,
fifteen fathoms in Geographe Strait, East Coast’’, observing ‘“ No
specimen, to our knowledge, has been taken near the shore”
Re-examination of these dredged specimens in conjunction with
the type series necessitated a consideration of Neozelanic and South
Australian shells. Untortunately we have not been able to criticize
Victorian examples, but we have the following facts to record. The
type set are obviously ‘‘shore shells’? and agree better with New
Zealand specimens than with any other, but here again no certainty
is possible, since they do not exactly agree, and, moreover, we have
two species collected on the New Zealand httoral; we have not seen
the dredged New Zealand specimens attributed to this species. We
particularly note this because we have two series from Tasmania, both
dredged, and these represent two species, both ditferent from the types
of inguinatus. ‘l'orr has also sent us two different species from South
Australia, which seem to agree with the Tasmanian forms or to differ
very slightly from them, we have not sufficient material to determine
which. However, all those we have yet examined seem to fall into
Parachiton, since the girdle appears to be covered with slender glassy
spikes, whilst enguinatus and the Neozelanic shore shells have the
girdle covered with small scales.
There may be a rare shore shell in Tasmania which will bear the
name inqguinatus, and there may be a shore shell in South Australia
which may bear the name J/iratus, as the description given refers
to a shore shell which seems to be a Lepidopleurus, but we have not
yet traced the type.
2. Evupoxorpnax, gen. nov.
This name is proposed for Chiton inornatus, Tenison - Woods.
Pilsbry, in his Monograph, took up a manuscript description, made
by Carpenter of a shell in the British Museum, under the name
Callochiton lobatus, placing it in the subgenus Sfereochiton from
Carpenter’s note, ‘‘ Girdle leathery, smooth, under a lens seen to bear
short minute sparsely placed hairlets.’”” Later Pilsbry recognized
this species was Tenison- Wood’s species above-named, and still later
sinking Stereochiton as a synonym of Zrachyradsia, noted the species
as Callochiton ( Trachyradsia) inornatus, ‘len.- Woods.
Recent acquisitions of many specimens show the Tasmanian shell
to reach a large size, and to differ appreciably from Callochiton and
approach very closely to Hudoxochiton. It differs from the latter in
the very wide leathery girdle with very short thin curved few and
minute little hairs, and may later be regarded as a subgenus of
Eudoxochiton.
3. PLaxrPHorA IN AUSTRALIA.
Under this heading one of us gave (Proce. Malac. Soc. Lond., vol. ix,
June, 1910, pp. 96-100) the results of the examination of a number
of specimens, concluding as follows :—
100 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
Plaxiphora costata (Blainville). Specimens from Queensland,
Tasmania, and South Australia.
Plaxiphora albida (Blainville). New South Wales, Victoria, South
Australia, and ‘l’asmania.
Plaxiphora peteliana, Thiele. New South Wales.
Plaxiphora matthewsi, Iredale. South Australia.
It was obvious from that paper that no definite result had been
achieved, and other workers found great difficulty in accepting these
conclusions. ‘he writer was just as dissatisfied, and later recorded
that he was still working on the matter. Herein is presented a reason
for reconsidering the whole subject, but material is demanded.
It has been abundantly proved by the large collections now
available that all Chitons are very local in their distribution, and
this suggests the criticism of series from definite localities. With
such series field notes should be considered and the variation
established. Thus ‘‘ Tasmania”? is of little use as a locality when we
know the northern shells may differ from the southern, and from the
south alone we seem to have three distinct species, not counting
matthewst, Iredale, which is not a Plaxiphora, strictly speaking, at all.
Tasmanian shells have been twice named, thus: P. albida (Blain-
ville), King Island; P. tasmanica, Thiele, new name for Chiton
glaucus, Quoy & Gaimard, from southern ‘Tasmania.
We have not yet examined actual topotypes, but Thiele has given
figures of the type of the first-named, and good figures were given by
Quoy & Gaimard as well as by Thiele of the other. As previously
stated, it is hoped to settle this matter in detail later, but we call
attention to it in the hopes of obtaining further co-operation, many
more specimens being necessary. Thus Torr has sent us shells from
St. Francis Island which he has ealled costata, publishing a note,
‘““Mr. Gatliffe, of Victoria, identifies this shell with P. bednalli,
Thiele.””? We are inclined to agree with Gatliff, and the shells are
certainly not costata (Blainville). Torr also sent us a topotype of the
latter, and it seems distinct from the South Australian shell we had so
identified. Further, South Australian shells do not seem to agree
with Tasmanian shells determined as albida (Blainville), so that
probably the former will bear the name of conspersa, Adams & Angas.
A further complication exists in Plaxiphora peteliana, Thiele. This
was described as from ‘‘'lasmania’’, and Iredale, probably wrongly
so determined a New South Wales species.
The items calling for urgent solution are: Does P. albida
(Blainville) exist in South Australia, and, if so, is P. conspersa,
Adams & Angas, synonymous? Does P. costata (Blainville) range
into South Australia and Tasmania, or is it represented by different
forms? Does P. bednalli, Thiele, range into West Australia, and, if so,
is not P. hedley?, Torr, the immature shell, and also is not this the form
recorded as P. albida(Blainville) by Thiele ? Again, does P. bednall,
Thiele, range into 'l'asmania or is it there represented by a closely
allied form? ‘These questions can only be answered by the study of
systematically made collections of numbers with field notes. This is
necessary, as it is quite impossible to gauge the merits of the cases by
IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 101
means of a few shells only. P. matthewsi, Iredale, is not involved in
the above medley, and we think one of the other species would quickly
be eliminated were collections available. We have taken the oppor-
tunity of figuring P. matthewsi, Iredale, from a Tasmanian specimen
so determined (Pl. V, Fig. 4). When it was described the peculiar
formation of the tail-valve which suggested Frembleya was remarked
upon. Receipt of well-preserved specimens from Tasmania show
that the species has no close relationship with Frembleya, the animal
being obviously different. This is now being investigated, but in the
meanwhile a nearer ally from a superficial examination might be
Loricella. This statement should prove how extremely interesting
this species is, and we hope that its exact status will be soon fixed.
The valve slitting recalls that of Callistochiton, and we note hereafter
that Thiele asscciated Lorica, Loricella, Squamophora, and Callistochiton
together. We discuss the association later, but believe most of the
resemblances of this species are simply due to convergence in develop-
ment, and are not of phylogenetic import.
4. AcANTHOCHITONS,
Torr, in his essay on South Australian Polyplacophora, observed,
““A splendid opportunity awaits the student who will make this
field a special study,” and recorded sixteen species. We confirm
Torr’s statement, and asan aid give the following notes. First, it is
now necessary for the student to collect in quantity, as we find the
species difficult to delimit without long series. It will be necessary
to continually use the microscope, and very many specimens must be
dissected.
The difficulty of distinguishing these Chitons may be lessened by
the usage of narrow generic groupings. Thus one of us advocated
the usage of six generic names, viz. : Acanthochitona, Cryptoconchus,
Cryptoplax, Notoplax, Macandrellus, and Craspedochiton. This was
after consideration of Thiele’s classification, which was based on
examination of the radula as well as microscopic shell-characters, and
which reads :—
“Genus Craspedochiton and subgenus Thaumastochiton.
Genus Aristochiton.
Genus Cryptoconchus with subgenus Spongiochiton and sections
Leptoplax and Notoplax.
Genus Acanthochites.”’
If this be accepted the following alterations are necessary on
nomenclatural grounds alone. Firstly, regarding the genus Crypto-
conchus with subgenus NVotoplar and sections Leptoplax and
Macandrelius. Notoplax is older than Macandrellus, which equals
Spongiochiton and Loboplax. We, however, would prefer Iredale’s
arrangement with the amendment that J/acandrellus may fall as an
absolute synonym of Notoplax. We have Tasmanian species which
completely combine any superficial differences apparent in the types
of the two generic groups. We would note, however, that Thiele
referred the Neozelanic species “ rubiginosus, Hutton” to Loboplax =
VOL. XII.—NOV. 1916. 8
102 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY
Macandrellus, whereas, superficially, it seemed typically a Craspedo-
chiton. Again, Thiele placed the Australian variabilis in Loboplax,
but we hoe no hesitation in disagreeing with this point. This
species (there may, however, be more than one confused under the
name) is of the “ereatest interest because it cannot be closely
correlated with any other Australian shell. More study than we have
yet given to it is necessary to determine the correct location of the
shell, and the animal must be carefully examined. Again, 1t must
be admitted that probably more than one generic form is confused
under the name Acanthochiton, even as restricted above, since the
~“bednalli”’? group seems somewhat different to the ‘ asbestordes”’
group. ‘These may, however, prove to stand in the same relationship
to each other as typical Wotoplax does to typical Loboplax. As one
of us admitted before, this is the most difficult group in the order
to satisfactorily determine, and we want much more material to
work upon.
5. CrYPTopLax.
Reeve described Chitonellus gunnit from Bass’ Straits, Tasmania,
but Pilsbry, in his Monograph, considered it a variety of striatus,
Lamarck, even as EK. A. Smith had concluded some years previously.
Consequently Bednall so recorded the South Australian shells. Torr
recently reverted to the name striatus, remarking: ‘‘ Chitonedlus
striatus of Lamarck describes our South Australian species
admirably... The breadth of the valves varies so much in stratus
that there seems no room for var. gunnit.”” Previously, May and
Torr had catalogued the Tasmanian shells as Cryptoplax striatus
(Lamk.), var. gunnii. Probably Torr had overlooked an article by
Pilsbry in the Proc. Malac. Soc., vol. iv, pp. 151 et seqq., March,
1901, entitled “ Morphological and descriptive notes on the genus
Cryptoplax”’, wherein Pilsbry clearly differentiated specifically
Cryptoplaz gunnii, Reeve, from Cryptoplax striatus, Lamarck. In
this paper Pilsbry used spirit specimens sent by Bednall from
St. Vincent’s Gulf, South Australia, giving a description on p. 156
and figures on pl. xv, figs. 17-19, 24-6, to be contrasted with
figs. 20-3 drawn from Port Jackson specimens of C. striatus,
Lamarck. British Museum specimens confirmed Pilsbry’s conclusion,
and North Tasmanian shells generally agreed. ‘The first Port Arthur
(South Tasmania) specimen attracted attention as differing from the
typical gunniz in being even more elongate. Mr. E. Mawle has
since collected more Port Arthur specimens, and these indicate the
solution of Torr’s perplexity, since two very distinct species are living
together in that locality. We had observed some differences in othes
collections, but were not certain of the exact source of the shells.
Mawle’s collection has placed us upon sure ground, and the additional
material we are now obtaining will enable us to deal with this matter
later in more detail.
In the meanwhile we can state that the two Port Arthur species
are quite different superficially and in detail, and that we suggest
one is the southern representative of “ striatus”’, while the other
IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 103
represents gunniz. This conclusion necessitates the redetermination
of South Australian shells and also West Australian ones. Torr has
sent a few South Australian shells, and here again two very distinct
species are confused, and it may even prove that more may be
recognized. The exact application of the name striatus is not yet
certain, for we have not ascertained the existence of the type, and
the description is very inadequate and no exact locality is given,
though Péron and Lesueur are cited as the collectors; this fact
suggests King Island.
6. IscHNnocuHrrons.
Tasmania appears to be very rich in species referred to Lschnochiton,
s.l., but the south has developed a most wonderful fauna of large
species, while the north has many Adelaidean forms. ‘Torr recorded
twenty species of Zschnochiton from South Australia, and the majority
of these may yet be found in northern Tasmania. Pilsbry, when
dealing with Port Jackson Chitons, admitted five subgenera, viz.
Ischnochiton, s.s., Heterozona, Stenochiton, Haploplax, and Ischnoradsia.
Thiele was more conservative still, for, dismissing Zaploplax altogether,
he only regarded Stenochiton, Heterozona, and Isehnoradsia as sections
of the subgenus Lschnochiton. Stenochiton and Ischnoradsia are super-
ficially so different that generic segregation isdemanded. The general
form of Haploplax differentiates this group, and the girdle-scales
being very different from those of /schnochiton we consider the name
should have generic rank. However, we would record that neither
mayit nor virgatus have any place in the group. Adult Leterozona
is a very characteristic shell in the peculiar girdle-scaling, and we
propose to use this name generically for somewhat novel reasons.
Firstly, the immature Heterozona cariosa has the girdle-scaling
normal, the scales being regular but smaller on the outer half of the
girdle. This is the regular girdle-scale formation in such a species
as fruticosus, Gould, and to some extent in the species known as
“contractus”’ (recte Uineolatus, Blainville). In the species known as
‘“divergens”’ (recte proteus, Reeve) and crispus, Reeve, the scales are
practically uniform in size to the edge of the girdle. Therefore, if
Heterozona were to be enlarged, it might reasonably include such
Shells as fruticosus, Gould. While we do not take this step at this
time we use Heterozona generically, as we describe a new species from
southern Tasmania which is the most highly developed of the group
yet known. In this the peculiar girdle covering is developed at an
early age, and is most noticeable at the first glance. We would thus
make use of Pilsbry’s five subgenera as genera, and if these are
utilized closer examination of shells becomes necessary and fewer
mistakes will be made. Again, we must note that long series are
necessary, as the very immature of many Ischnochitons are quite alike
in form, lack of sculpture, and girdle-scaling. Further, the girdle-
scales of juvenile specimens appreciably differ from those of the
adult, even when the latter are not referable to Heterozona.
Since the preceding was written we have been surprised by the
dissections of the new species J. mawlei. A peculiar and beautiful
104 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
Ischnochiton with extraordinary lateral sculpture was all it impressed
us as. The girdle-scales were certainly slightly abnormal, in that
they were more regular than those of ‘‘ contractus”’ auctt., with little
or no leaning to the fruticosus style. We found, however, that all
the median valves had two, three, or four slits, instead of the single
one anticipated by us. Consequently it fell into Pilsbry’s subgenus
Ischnoradsia, which in no other item did it resemble. While this
proved the inadvisability of accepting Pilsbry’s differential features it
did not relieve us from our dilemma. We purpose having the animal
investigated and will then decide as to its exact status. - In the mean-
while, to fix the peculiar systematic position of the species we provide
for it the new subgeneric term ANISORADSIA.
When Hull described Jschnochiton faleatus he recorded that he had
received the same species from one of us under the name J. tateanus,
concluding that an error had been made by Tate & May in 1901 when
they included the latter species in the Revised Census. Confusion
occurred through this note, and consequently netther species appeared
in May & Torr’s List, whereas the fact is that both species or their
representatives do occur, and were dredged together. Further, either
I. faleatus or a nearly allied shell also occurs in South Australian
waters. The Tasmanian and South Australian shells known as
I. crispus (Reeve) differ appreciably from New South Wales shells,
which are typical, as shown by the types in the British Museum.
The Victorian shell received as a varietal name decorata by Sykes,
and at the present time this may be used specifically for the Victorian,
Tasmanian, and South Australian form.
7. Curron toneicymBa, Blainville.
Blainville described this species in 1825. Quoy & Gaimard utilized
this name for a common Jschnochiton found in Australia and New
Zealand. ‘l'his usage persisted until 1892, when Pilsbry separated the
Australian species from the Neozelanic, retaining the above name as
of Quoy & Gaimard for the latter, definitely stating that this was not
Blainyille’s species. ‘This disposition was accepted until one of us
indicated the falsity of this procedure and definitely distinguished the
Neozelanic shell with a new name. ‘This, however, did not finish
the matter, for Blainville’s species still remained unrecognized. The
same writer has continually endeavoured to fix this name and so
effectually rid our nomenclature of an irritating item. The constant
examination of the present collections has enabled us to record
a favourable, though quite unanticipated, result. Blainville’s descrip-
tion not being commonly accessible, we here transcribe it :—
‘« C[hiton | longicymba, Dufr. (Blainville, Dict. Sci. Nat. (Levrault),
vol. xxxvi, 1825, p. 542).
“Corps trés-alongé, trés-étroit; limbe couvert de trés-petites
écailles comme farineuses; coquille trés-longue, composée de huit
valves grandes, croissant de la premiére a la derniére, convexes et
parfaitement lisses ; les intermédiaires avec des aires latérales larges,
distinctes par une saillie anguleuse; couleur générale d’un vert
brunatre, varié ou panaché de petites taches blanches, plus larges sur
IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 105
la ligne dorsale. Cette jolie espéce existe dans la collection du
Muséum; elle provient des rivages de Vile King.”
The recognition of this species is very easy when the keynote is
touched. Hitherto we have always been searching in the wrong
place, looking at Ischnochitons with sculpture, whereas Blainville
wrote ‘‘ valves . . . parfaitement lisses ’’.
Rochebrune described a large number of Chitons in the Paris
Museum, generally hiding every clue to their identity under ~
a peculiarly false generic location. Thus he described Schizochiton
nympha (Bull. Soc. Philom. Paris, ser. vir, vol. viii, p. 36, 1884) from
King Island, collected by Péron & Lesueur. No one could possibly
be expected to guess that so far from being a Schizochiton, this species
was exactly the opposite in every generic feature, being a Stenochiton.
Yet Thiele, from an examination of Rochebrune’s type, has showed this
and given figures to support his conclusions. In a similar case one of
us showed that Rochebrune had redescribed the type of a species
named by Quoy & Gaimard, and this enabled us to reconcile the loss
of the type of C. longicymba, Blainville, with the presence of Schizo-
chiton nympha, Rochebrune. f
From Thiele’s description and figures there is certainty that
Rochebrune renamed the Blainvillean species, and that Chiton
longicymba, Blainville, is a Stenochiton. Thiele does not definitely
make this a synonym of Stenochiton juloides, H. Adams & Angas,
and until King Island specimens are again collected we prefer to
allow Stenochiton longicymba (Blainville) as a separate species.
Blainville definitely named four species as coming from King Island,
viz. C. lineolatus, C. longicymba, C. hirtosus, and C. albidus. Thiele
disposed of the last two, and we now recognize the two first-named.
Thus C. dineolatus is later shown to be the species known as “ J. con-
tractus, Reeve’’, but which is not Reeve’s species. The status of
C. longicymba has just been discussed, while C. albidus from examina-
tion of the type-specimen still existing must be used for one of the
common species of Plaxiphora.
Though Thiele recorded that C. hirtosus was based on the shell
later described by Quoy & Gaimard as C. georgianus, from King
George’s Sound, and therefore the locality ‘‘ King Island’ was
erroneous, he did not use it. We had referred the species to the
genus Scelerochiton, though Thiele selected Liolophura, but here we
simply note that Sclerochiton is untenable, the name being preoccupied,
and for the Chitons so named, Squamopleura, Nierstrasz, seems avail-
able: of which more at a later opportunity.
8. Hzrerozona susvirinis, n.sp. Pl. IV, Fig. 2.
Shell of full size for the genus, elliptical, valves low, semi-carinate,
keel often obsolete, side slopes arched, valves not beaked. Colour
varied, generally of shades of blue-green with lighter stripes and
mottling; many specimens show a dark dorsal stripe succeeded on
each side by whitish stripes; some specimens combine with the bluish
shell a beautiful red-brown girdle, others even a golden girdle,
though usually the girdle is darker blue-green. ‘The characteristic
106 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
coloration has suggested the specific name, but some colour-aberrations
occur in which the green is lacking, being pale cream splashed with
white and orange, though green even here sometimes recurs. The
following description of the sculpture is drawn up from a perfectly
normal specimen of small size selected as the type.
Anterior valve regularly radially ribbed with about fifty flattened
ribs. Median valves have six to eight similar ribs on the lateral
areas; the pleural areas have a few longitudinal wrinkled threads
near outer edge of the pleura, the rest of the pleura and jugum
covered with fine zigzag wrinkled lines. Posterior valve regular
and normal; mucro elevated about anterior third; sculpture of
posterior half lke that of the anterior valve; anterior portion
sculptured like the pleura. Variation in the sculpture occurs
according to age in that the ribbing on the anterior valve and lateral
areas of median valves increases through divarication and also tends
to degenerate into nodules through the intersection of the concentric
erowth- lines. The posterior area of the tail-valve shows this more
stro ngly, appearing in some cases coarsely nodulose. Further with
age, the pleural sculpture becomes finer and the zigzags predominate.
Girdle-scales distinctive ; near the shell small pointed or tending to
mucronate scales bearing striz, and comparatively regular for about
half the width of the rather broad girdle; the outer half covered
with minute scales, irregular and somewhat varying in size.
Length of type 30mm., breadth 16mm. Dried shell. Length
of largest specimen (dried) 49 mm., breadth 24mm.
The series examined shows two phases, a lower broader shell and
a higher narrower shell; they are certainly conspecific as far as can
be determined at the present time, and the only suggestion we can
make is that the differences may be sexual. This suggestion is being
investigated as it may explain the discrepancies observed in other
eases. ‘he internal structure is quite normal, the coloration varying
slightly as the outer coloration varies.

9. CHrron conrractus, Reeve.
The locality given when this species was described was ‘‘ New
Zealand”. When Pilsbry dealt with it (Man. Conch., vol. xiv, 1892,
p. 93) he did not comment upon this, but simply gave “Tasmania
(Mus. Cuming.)”’. This was taken from Carpenter’s “Manuscript, the
quotation reading, ‘‘ There are 3 specimens in the Cuming collection,
from Tasmania, and two on the same tablet which are really an
intermediate variety of J. castus’ As synonyms, also following
Carpenter, Pilsbry added Chiton decussatus, Reeve, Chiton castus,
Reeve, and Lepidopleurus speciosus, H. Ad. & Angas. Later, in the
Nautilus, vol. viii, p. 129, March, 1895, Pilsbry recorded, ‘‘ By the
study of many specimens received from Messrs, Bednall & Cox, I find
that two species were ‘lumped’ under the name IJschnochiton
contractus. (1) ZL. decussatus, Reeve, of which castus, Reeve, and
IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 107
speciosus, Ad. & Ang., are synonyms, and (2) contractus, Reeve, of
which Mr. Sykes considers pallidus, Reeve, a synonym.” ‘This
conclusion was accepted by Bednall, though he observed he was not
satisfied. Confusion of more than one species under the name
contractus in ‘lasmania urged reconsideration from first principles,
when it was found that the description of contractus was only
applicable to the shell known as decussatus, specimens being available
that agreed absolutely with Reeve’s figure and description. Reeve
wrote, ‘terminal valves and lateral areas of the rest concentrically”
granulated, granules solitary.” This is quite definite and sufficient
to fix the species, and when this is accepted the exact shape and
coloration are seen to agree. Search in the British Museum showed
that the description and figure had been taken from a specimen of
decussatus on the same tablet as specimens of ‘“‘ contractus auctt.”,
and this had apparently been selected as being the most perfect.
Consequently the name contractus undoubtedly refers to the species
known as decussatus, and the synonymy given in the Man. Conch. by
Pilsbry is exact. We had drawn up a description of ‘‘contractus
auctt.’? when we recognized that the description of /ineolutus given
by Blainville was absolutely applicable. We reproduce the latter :
‘ C[hiton | lineolatus (Blainville), Dict. Sci. Nat. (Levrault), vol. xxxvi,
1825, p. 541). Coll. du Mus.
‘Corps ovale, assez alongé; les aires laterales des valves inter-
médiaires moins distinctes que dans les espéces précédentes, et offrant
des stries nombreuses sur les bords; les écailles du limbe trés-petites ;
les dents des lames d’insertion non pectinées; couleur variée de
petites taches longitudinales brunes sur un fond jaunatre. Cette
espéce, assez rapprochée de l’oscabrion alongé, a été rapportée de Vile
Kang par M. Péron et Lesueur.”’
Sykes has recorded C. pallidus, Reeve, as a synonym, but the
description is of a smooth shell of unknown locality. The tablet
bearing the name has specimens of ‘ contractus”? upon it, as Sykes
recognized, but the particular shell figured and described by Reeve
is there also ; it is a smooth shell, due to extr aordinary wear, and differs
in shape and is quite indeterminable, but ¢extilis is suggested, and it
very probably is no¢ Australian. We give the synonymy of the two
species as we now make it.

description, since the shell we figure is well known, and complications
occur in specimens from southern Tasmania which we have not yet
completely cleared up.
The typical form is very common in South Australian waters,
where little variation exists. One of us collected it in the Flinders

10. Iscunocurron (ANIsorapsIA, n.subg.) MAWLEI, n.sp. Pl. IV, Fig. 4.
Shell of full size for the genus, elongate elliptical, valves round-
backed, low, not keeled nor beaked. Colour uniform pale yellow.
The following description of the sculpture is drawn up from a small
normal specimen selected as type.
Anterior valve sculptured, with fifty to sixty low radials, which are
curved, straggling, convergent, and more or less undefined, so that
scarcely any one can be traced from apex to edge. Median valves
show the same sculpture on the lateral areas, but more irregular
development still is here noticeable. The pleural areas are sculptured
at the sides with irregular longitudinal threads, more or less wavy,
which become obsolete towards the jugum, the dorsal area being
covered with fine zigzag scratches. ‘Tail-valve large with mucro
elevated at about the anterior third, posterior slope straight. Posterior
area sculptured like the anterior valve, but more roughly, separated
lozenges commonly occurring ; anterior sculpture like that of pleura
of median valves. Variation in sculpture is slight, age developing
moré radials on anterior valve and lateral areas of median valves,
while concentric growth-lines become more prominent and tend to
form lozenges on these areas, the posterior area of tail-valve generally
showing this lozenge formation more boldly. Interior coloration pure
white. In young shells both the tegmentum and articulamentum are
brittle. The sutural lamine and teeth are typically Ischnoid, but
the latter are very short. In the anterior valve twenty slits were
counted in a senile shell, twenty-five in a young one, the teeth
irregular in shape. In the posterior valve eighteen irregular slits
were noted in the senile shell, eighteen regular ones in the young
one. In the median valves the sinus is broad, about one-third the
breadth of the valve, the sutural lamine are long and evenly shaped ;
the lateral teeth are very short, exceeded by the tegmentum, and two,
three, or four slits occur. The external appearance of the shell is
distinctive, but detail figures of the valves will be given later. Girdle

broad, covered with regular imbricating small scales; in the young
shell these are oval, sub-erect, with ten to twelve deep grooves, the
apex smooth. Adjacent to the shell these are longer, narrower, and
more erect. Small squarish granules adorn the edge. In a senile
shell the scales are all more erect and more deeply grooved, while
they are more irregular in shape. Length of type (dried shell)
34mm., breadth 18mm. Collected by E. Mawle at Port Arthur, -
South Tasmania.
Range: south coast of Tasmania.
This distinctive species cannot be confused with any other
Australian shell, differing as it does in shape, colour, sculpture, and
internal features. It is a very fine discovery, as it grows to 51 mm.
X 24mm. in the dried specimen. We have already indicated that
its relationships are obscure and its range is very restricted so far as
at present known, for such a conspicuous shell could not escape notice
by collectors as keen as those of Victoria and South Australia.
11. CuHrron pivErGENsS, Reeve.
Reeve’s description and figure were not carefully considered: by
Pilsbry when he separated divergens, Reeve, from fruticosus, Gould,
and made Chiton proteus, Reeve, synonymous with the former.
Pilsbry wrote ‘‘Girdle covered with large scales’’, and remarked,
“7, divergens has been erroneously united to fruticosus by Angas and
by Haddon.”? Angas and Haddon were, however, quite right, as the
figure shows, and the description ‘‘ ligament horny, very finely
granulously coriaceous’? is very definite. Reeve’s diagnosis of
Chiton proteus is a perfect description of the shell Pilsbry considered
“‘ divergens”’. Tasmanian shells recorded under the latter name do
not agree with specimens of proteus and are here distinguished.
We may note that in the British Museum the shell apparently
figured by Reeve as C. divergens is on a tablet now labelled fruticosus
(quite correctly), while the type of proteus appears to be on a tablet
labelled ‘‘ divergens’?.
12. IscHNOCHITON MILLIGANI, n.sp. Pl. V, Fig. 2.
Shell of full size for the genus, narrowly elongate, not appreciably
tapering at the ends, elevated, gothic arched, valves not beaked
nor keeled. Colour varied: greenish of dull shades longitudinally
streaked with darker. Anterior valve small radially, closely ribbed,
with numerous low riblets, often divaricating, forty to sixty or more
according to size. Median valves deep; lateral areas radially ribbed
as anterior valve, eight to twelve ribs being counted; ribs low and
close together. Pleura finely ridged at sides, ridges straight, succeeded
on jugum by finer sculpture which is sometimes zigzag in character.
Tail-valve large, mucro elevated at anterior third, posterior slope
slightly concaye; sculpture of posterior area as of anterior valve and
anterior portion sculptured as pleural areas. Girdle-scales large,
oval, and very regular, deeply grooved with eight to ten grooves.
Interior with red markings, a red horseshoe clearly seen in tail-valve ;
slitting regularly Ischnoid in character, head-valve in young shell

having 13 slits, old shell 9 slits, median valve 1 slit, tail-valve in
young shell 138 slits, in old shell 11 slits.
T'ype from Port Arthur, southern Tasmania, collected by E. Mawle.
Length 41, breadth 19mm. Largest shell: length 59, breadth 27 mm.
Range: coasts of Tasmania.
This species differs from Z. proteus, Reeve, in the finer sculpture of
the terminal valves and lateral areas of the median valves, while the
pleura shows much coarser sculpture. It grows to a much larger
size, and the scales of the girdle are comparatively smaller.
Compared with a typical specimen of proteus of the same size, the
anterior valves show 40 ribs, the laterals 6-8, the posterior 40 ribs,
as against anterior 35, the laterals 4-7, the posterior 28-30 for proteus
(PL. V, Fig. 2a”). The figures will show the differences, which become
emphasized as larger specimens are examined.
13. IscuNnocuiron arkrnsont, n.sp. Pl. IV, Fig. 3.
Shell small, elongate oval, elevated, round-backed, valves not
beaked. Colour uniform buff. Anterior valve coarsely quincuncially
punctate, though obscure radials can be distinguished; the type-
specimen figured is half-grown only, since the valves become eroded
and brittle at a very early stage. In the senile shell obscure radials
predominate on the anterior valve. Median valves have the pleural
areas coarsely quincuncially pustulose, the pustules round, flat-topped,
and finer on the jugum, which is always much eroded in senile shells.
The lateral areas are well elevated, pustulose only in the adult,
coarse, nodulous radials being developed with age, that are, however,
dominated by the concentric growth-lines so that they appear as if
concentrically granulose. The posterior valve is pustulose in the
immature stage, which first shows the development of stronger
sculpture. In the senile shell the mucro is elevated and central, the
posterior slope slightly convex, sculptured with apparently elongate
nodules, caused by the intersection of the radials with the growth-
lines. Gurdle-scales regular, very small, and finely striate. Internal
coloration white; slits normally Ischnoid, nine in anterior valve,
one in median valves on each side, eleven in posterior valve.
Type collected by Mr. E. D. Atkinson, J.P., at Sulphur Creek,
northern Tasmania.
Length 8, breadth 4:5 mm. Senile shell: length 13, breadth 7 mm.
Dried shells.
Range: northern Tasmania. Also collected by Dr. Torr.
The minute striated scales of the girdle at once distinguished this
small species from the immature of Z. decoratus (Sykes), and there is
at present no other species with which it can be confused. It
suggested ‘‘gryer’”’ recorded by Dr. Torr from South Australia, but
we find it quite distinct, as will later be shown.
14. Cutrron usrunatus, Reeve.
Angas, in 1867, recorded Lepidopleurus ustulatus (Reeve) from Port
Jackson. Pilsbry (Proc. Acad. Nat. Sci., 1894, p. 70, footnote)
commented ‘‘ Jsehnochiton ustulatus, Reeve, occurs abundantly in
South Australa, but nothing I have seen from Port Jackson
IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 111
corresponds to this species”. Bednall (Proc. Malac. Soc., vol. 1,
April, 1897, p. 144) then recorded a species under this name, giving
a very fine word-picture of the shell, and observing, ‘‘ Kecorded by
him [Angas] from New South Wales, where it does not appear
to occur. I have received specimens of J. divergens (= proteus) under
this name.” Bednall’s species does not agree with the type of
teeve’s species, but is a very distinct unnamed shell. We would note
that Sykes (Proc. Malac. Soc., vol. ii, July, 1896, p. 88) also recorded
Ischnochiton ustulatus (Reeve) from Port Phillip. We have not seen
the shells so named, but they may have been the true wstulatus, since
there are shells in the British Museum dredged in Port Phillip which
agree very closely with the type lot of ustwlatus, Reeve.

Chiton ustulatus, Reeve.
Shell of full size, for the genus narrowly elongate, girdle broad,
elevated, round-backed, valves not beaked. Colour red brown,
longitudinally striped with cream, stripes more prominent om the
dorsal area, lacking on head-valve. Anterior valve very finely
radially ribbed, about fifty being counted on normal specimen.
Median valves, with lateral areas strongly elevated, similarly
sculptured, but sculpture commonly tending to elongate lozenge
shapes through growth-lines. Pleural areas very finely quincuncially
punctate, somewhat linear towards edges, even fine on the jugum.
Tail-valve with mucro elevate, ante-central, posterior slope a little
concave; the posterior sculpture like that of anterior valve, but
much more cut into lozenges by the concentric growth-lines.
Internal features normal. Girdle very broad, covered with microscopic
scales, not distinguishable with an ordinary lens. This is diagnostic.
Under the microscope the scales are seen to be elongate ovals, a little
variable in size, flattened, and closely imbricating; they average
about a tenth of a millimetre long, and are finely striated with about
twelve striz.
'ype from Barren Island, Flinders Group, collected by W. L. May.
Length 29, breadth 14 mm.
Range: Adelaidean region from Flinders Group to West Australia,
recorded by Torr and Thiele.
This very distinct species stands quite alone, not only in shape,
coloration, and sculpture, but in its microscopic girdle-scales. We
have given a section of the girdle of one of the type series of Chiton
ustulatus, Reeve, for comparison, drawn from the specimens in the
British Museum (Pl. V, Fig. 3a”). We have not yet recognized
Reeye’s species, though it certainly seems Australian.
16. IscHNorapsta EVANIDA (Sowerby).
In the ‘‘ Mag. Nat. Hist. (Charlesworth) ”’, vol. iv, June, 1840,
Sowerby described (p. 290) Chiton australis (Conch. Illus., fig. 46),
Australia, and (p. 291) Chiton evanidus (Conch. Illus., fig. 139), New
Holland.
112 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
The descriptions and figures are good.
When Reeve wrote his Monegraph he doubtingly made the latter
synonymous with the former, introducing as new species pl. XVil,
sp. 104, Chiton metallicus, Australia, Mus. Cuming, and pl. xxi,
Sp. 142, Chiton novehollandia, New Holland, Mus. Brit. Pilsbry
made evanidus and metallicus synonymous with australis, writing :
“The synonymy .. . is unquestionable,’ and giving as habitat
‘¢ Port Jackson, Australia”. J. novehollandie was admitted as distinct
from ‘‘ Adelaide, S. Australia’. Shells from the two localities
named (New South Wales and South Australia) are very distinct.
Recognition of two forms in Tasmania necessitated re-investigation,
which revealed that the form recorded as ‘‘ australis” from that
locality had little to do with the typical Sydney shell. The
description of evanidus gives as the salient features ‘‘ central areas
smooth in the middle, faintly striated at the sides; lateral areas
rather elevated, with radiating granular strie”’. This disagrees with
australis, but describes the eastern l'asmanian shell very exactly.
The north-west Tasmanian form differs in the absolute smoothness
of its pleural areas and seems identical with the South Australian
shells known as JL. novehollandie (Reeve). It is easy to separate
these when series are compared, but individuals are not so clearly
differentiated, and we are not certain about immature shells, the
north-west form being apparently more elevated. However, the
species of Jschnoradsia seem to have exceedingly narrow limits, so
that for the present we may recognize two species in Tasmania. We
make this observation because we have an undescribed species from
Caloundra, Queensland, which is exceedingly like evanida, though
the very different australis intervenes geographically.
17. Lortca crmorra (Reeve).
In the Conch. Icon. Chiton, pl. vi, sp. 31, fig. 31, February,
1847, Reeve figured and described Chiton volvox from specimens in
the Mus. Cuming, collected at Sydney, New Holland, by Jukes.
Later in the same work (pl. xxi, sp. 141, fig. 141, May, 1847)
Reeve added Chiton cimolius from the same collection, the only
locality given being Australia: he observed, ‘‘ Allied in form, but
not in sculpture, to the C. volvoxz; at a loss for a name, I have
distinguished its resemblance in colour to the common fuller’s clay.”’
The differences are not clearly defined in the descriptions, but we
note with regard to the former ‘‘ridges narrow, slightly waved,
interstices peculiarly crenulately latticed”’, and to the latter ‘‘ central
areas smooth in the middle, ridged on each side, ridges thin, scarcely
granulated, interstices hollowed ’’.
In 1871 Angas, recording Zorica angast from Port Jackson,
commented (Proc. Zool. Soc. London, 1871, p. 97), ‘‘ A species quite
distinct from JZ. cimolia, Reeve, of which Z. volvox, Reeve, is a
synonym.”’
In the Man. Conch., vol. xiv, p. 237, 1893, Pilsbry accepted
this synonymy, probably following Haddon (Rep. Zool. Res.
Challenger, vol. xv, Polyp., p. 31, 1886), writing, ‘‘ The differences
IREDALE & MAY: MISNAMED TASMANIAN CHITONS, 463)
between ZL. volvox and L. cimolia are easily effaced when a good
series is examined.” He also suggested Chiton rudis, Hutton, as a
synonym. Hutton’s species was based on a specimen in the Colonial
Museum, Wellington, New Zealand, supposed to have been collected
in that country. This determination has been accepted by all workers
since, Bednall, Suter, Torr, Thiele, and ourselves all passing this
synonymy without question.
The consideration of the present collection necessitated a review,
and with the types of Reeve’s species, topotypes of the first-named
species, South Australian specimens, and shells purporting to have
been collected in New Zealand we find that Lorvea cimolia, Reeve, is
the name for the Tasmanian species, which differs at sight from the
New South Wales shell in lacking the very distinct latticing between
the longitudinal ribs of the central areas. The ribs are more distant
and not so definite; the girdle-scales differ in size, and there are
other minor differences. Basset Hull (Proc. Linn. Soc. N.S. Wales,
vol. xxxv, 1910, pl. xvii, figs. 1, 2) gave illustrations of half-valves
of the fossil Lorica duniana, n.sp., and the recent Z. volvoz,
Reeve. Relying on the excellent illustrations, we cannot separate
the recent Tasmanian and South Australian species from the fossil
LL. duniana, which would thus become a synonym of JZ. eimolia,
Reeve. It may be possible later on to differentiate southern
‘Tasmanian from South Australian shells, but typical Z. volvox cannot
be confused with either. The juveniles of the two species also show
striking differences in many respects.
Lorica was reduced by Thiele to subgeneric rank under Callistochiton,
Loricella and Squamophora being given similar rank. Thiele over-
looked the fact that Loriea had priority, and that Callistochiton would
be the name to suffer. We cannot see, however, that there is such
a close relationship, and maintain all the groups with generic value
and suggest later that they will not be closely associated.
Squamophora seems very near to Loricella, but when the juveniles of
Loriea, Loricella, and Callistochiton are compared little resemblance
is found. With regard to the genus Callistochiton, we would note it
has been badly handled in Australia. The generic (or family)
characters have been taken as specific, and hence orr recorded that
he had traced C. antiquus from Queensland to West Australia. The
northern Queensland shell differs from the Sydney one, which is
easily separable from the South Australian form, which, however,
may be the one inhabiting Bass’ Straits, and may range to south-
west Australia. The southern Tasmanian shell is, however, so very
different that we are dubious of every record we have not personally
investigated; and we note variation among unlocalized South
Australian examples.

The history of the genus Sypharochiton in Australia is complex.

from New Zealand. Gray in 1843 added another species, Chiton
IREDALE & MAY: MISNAMED TASMANIAN CHITONS. 115
sinclair?, also from New Zealand. In 1847 Reeve figured the latter
species with the locality ‘‘ Van Dieman’s Land. Dr. Sinclair”. In
1877 Tenison- Woods included this species 1m the Tasmanian ueneant
but noted ‘‘ Locality doubtful. N.Z. species”. In 18938 Pilsbry
included in the Manual C. pellisserpentis and C. sinclairi, but only
gave for each the locality New Zealand. The next year Cox added
Sydney as a locality for the former species, and later observed
that he had specimens from Port Jackson which he took to be
C. sinclairi. he same year Pilsbry stated he could not separate the
Sydney shells sent him by Cox from Neozelanic specimens. In 1901
Tate and May replaced C. sinelairt by C. pellisserpentis on the
Tasmanian list. In 1912 May and Torr write of C. pellisserpentis
as ‘*the commonest of all ‘'asmanian Chitons”’, while a similar shell
is common in Port Jackson. ‘The southern Tasmanian shells differ
appreciably from Neozelanic shells in shape, elevation, sculpture, etc.
In order to gauge the value of these differences we have studied
Neozelanic shells from many localities from Auckland to Otago, and
though we have observed vz ariation we have not been able to confuse
Australian with Neozelanic shells. Robin Kemp collected for one of
us a long series of this genus in Sydney Harbour, and these are
obviously separable from ‘the Tasmanian shell and m: my of them
suggest C. sinclairi. It is possible that there are two species of the
genus also represented in Sydney Harbour, just as there appear to be
two in South Tasmania. Certain shells have been found in the latter
locality having the lateral areas as well as the pleural areas smooth.
We have not yet fixed the status of this smooth shell. If it be an
aberration of the present species it is unparalleled in the Neozelanic
species, unless C. torrt, Suter, be its equivalent. The question at
once arises, should these be classed as sub-species or species? We
have carefully considered this matter in connexion with southern
Tasmanian shells, of which we have the following representatives :
Sypharochiton maugeanus, Yas., and S. pellisserpentis, N.Z.; Lschno-
chiton milligani, Tas., and L. proteus, N.S.W.; Ischnochiton decoratus,
Tas., and J. erispus, N.S.W.; Callistochiton mawlet, Tas., and
C. antiquus, N.S.W.; Lorica cimolia, Vas., and L. volvox, N.S.W. ;
Rhyssoplax diaphora, Vas., and R. rugosa, N.S.W., and others.
It is obvious that the last three could not be treated as subspecies,
and in the case of J. decoratus, Sykes, we have three closely allied
species living together, scarcely any more difference being observed
than between the l'asmanian J. decoratus, Sykes, and the New South
Wales Z. crispus (Reeve). In the present case we have S. pellisserpentis
(Q. & G.) and S. sinelairi (Gray) living together, and it is possible
two pairs also occur together in Australia and Tasmania. Thus,
while not dogmatizing, it seems best, until we know these faunas
better, to treat each on its merits as specifically distinct, for to
accurately settle the matter long series must be collected in many
localities.

straight, median valves beaked. Colour generally green, end-valves
and lateral areas of median valves concentrically lined with white or
pale greenish, dorsal area with dark-brown triangular patch, apex of
triangle posterior, sides orange marbled ; pleura green, with furrows
in some cases blue-lined. In some specimens the orange marbling
overruns the dark dorsal patch, and also extends on the pleura, the
ribs becoming orange-brown. ‘The general appearance is, however,
more or less uniform. On the tail-valve there is a very narrow white
patch, more or less triangular from the mucro to the girdle, where
a broader and more extensive white patch is observed. Anterior valve
very perpendicular, smooth. In senile shells an obsolete radial ribbing
may be distinguished under a strong lens. Median valves have the
lateral areas well raised and smooth, but in senile shells concentric
growth-lines are prominent and obsolete radial ribbing is rarely
present. The pleural areas are cut by longitudinal furrows which are
distant and reach across the valve for half its height, fading away as
the jugum is approached. In other words the pleura are sculptured
with shallow ribs, a broad smooth triangle being observed on the
jugum. In the type figured ten grooves can be counted on the half-
valve, four of which extend across the valve; in the largest specimen
sixteen grooves appear, seven extending across the valve. Tail-valve
with the mucro elevated at the posterior third, the posterior slope
slightly concave and smooth, the anterior area sculptured like pleural
areas. Girdle-scales shining, obsoletely striate, and of varied colours.
Rounded in shape, they are much smaller near the girdle-margin, and
are largest in the centre of the girdle. Internal features typical of
Rhyssoplax. Sinus very narrow. Colour inside pale blue-green with
the sutural lamine white.
Type from Norfolk Bay, southern Tasmania.
Length 31, breadth 17 mm.
Range: southern Tasmania.
This shell has been known as Chiton jugosus, but it differs at sight
from the typical Sydney shell in the pleural sculpture. It seems
more nearly allied to C. torrid = torrianus, Hedley & Hull, but it
cannot be regarded as a subspecies thereof, nor can it be so classed in
connexion with R. jugosa. We give diagrams of sections through
the pleural areas of each species, taken at right angles to the girdle
(P1. V, Fig. laanda”). In South Australia there lives another species,
classed as C. jugosus, which is nearer to that form, but it lives with
R. torriana, and so complicates the matter. Moreover, the West
Australian shell called &. torrdana differs at sight from the South
Australian species. Additional material is needed to accurately fix
the status of these forms, but there is little doubt this shell is
specifically distinct.
III. Groeraruicat Nores.
We have previously noted the importance of the Chiton fauna of
Australia in connexion with zoogeographical problems, and have
cited them in support of Hedley’s theory of the Bassian Isthmus.
The results of the present study are striking and such as we had not

ventured to anticipate. We find that not only are the Peronian
Chitons quite distinct from the Adelaidean ones,but that no Peronian
species occurs in Tasmania without local variation. Further, that
a different Chiton fauna is developed in the south and south-east
bays from that of the north coast. The latter is practically pure
Adelaidean, but there isa slight Tasmanian element. This Tasmanian
element is strongly emphasized in the south-east, and shows such
peculiarities that we propose to designate the east coast of Tasmania.
the Maveran Recion, and separate it from the Peronian Region,
which we restrict to the east coast of Australia from Bass’ Straits to
Caloundra, Queensland. This nomination will attract zoogeographers,
and we anticipate confirmation from study in other divisions of
molluscs, and also other branches of natural science. As distinctive
of the Maugéan Region we would cite the species Jschnochiton mayt,
Pilsbry, Z. (Antsoradsia) mawlet, Heterozona subviridis, and Callisto-
chiton mawlet, described in this paper. ‘The genus Hudoxoplax
has worked into the Adelaidean Region, but not into the Peronian,
while other genera such as Sypharochiton range into the Adelaidean
only as far as Tasmania is concerned, though otherwise represented
in the Peronian region. Larger and more extensive collections may
add further novelties and make the subject more interesting still.

ON AMMONITOCERAS TOVILENSE FROM THE LOWER
GREENSAND (APTIAN) OF KENT.!
By G, C. Crick, F.G.S., ete.
Read 9th June, 1916.
PLATE VI.
Tae specimen which forms the subject of the present note belongs
to the British Museum collection [B.M., No. C. 14671] and came
from the Hythe Beds of the Lower Greensand (Aptian) at Tovil,
near Maidstone, Kent. When obtained only a portion of the outer
whorl of the specimen was visible, the rest being covered by extremely
hard matrix; the greater part of this, however, has been successfully
removed by Mr. Richard Hall, one of the formatores at the Museum,
and to him therefore we are indebted in no small degree for the
admirable specimen described below.’
The fossil is fairly complete; the body-chamber occupies about
three-fourths of the last whorl, but the aperture is not preserved.
The shell is evolute, the whorls being just in contact. Unfortunately
the youngest part of the shell is not exposed and may not be
preserved; the shell begins where the coil has a diameter of about
55 mm., and three whorls are preserved. ‘lhe diameter of the whole
specimen is about 510mm. (about 20 inches), the width of the
umbilicus (measured from suture to suture) 225 mm., and the height
of the outer whorl about 164mm. The whorls are subcircular in
cross-section, wider than high, and increase rapidly. At a point
about 100mm. (measured along the median line of the periphery)
from the anterior end of the specimen the thickness of the whorl
including the rib is 186 mm., and excluding the rib 170 mm., whilst
the height of the whorl including the rib is 160mm. The earliest
part of the surface of the specimen is much damaged, and the precise
nature of the ornaments cannot be seen until the shell has attained
a diameter of 132mm. Here the test is ornamented with coarse
rounded ribs separated by intervals rather wider than the ribs; the
ribs are somewhat reclined over the greater part of the lateral area,
and at the umbilical margin of the whorl curve a little more forward
as far as the suture of the shell. From the point where the shell has
a diameter of 132 mm. the whorl exhibits at intervals a double row of
tubercles, a fairly sharp one on the umbilical margin and a larger,
more obtuse one on about the middle of the lateral area. Between
the umbilical tubercle and the suture of the shell there are sometimes
two ribs, at other times only one, rather stouter than the rest. Each
pair of tubercles is connected mostly by three prominent ribs, and
trom the outer tubercle there are usually three ribs passing over the
periphery of the whorl, without interruption, though sometimes with

a slight flattening or even a slight depression on the central part
of the peripheral area. The rib connecting each pair of tubercles
becomes gradually stronger until, where the diameter is 850mm.,
most of the fine ribs of the test have disappeared, the outer tubercle
becomes more compressed and gradually approaches the periphery ;
the three ribs connecting it with its fellow on the opposite side are
relatively coarser and have an orad convex curve. Later the finer
ornaments disappear except on the inner area of the whorl, and the
shell is ornamented with strong compressed ribs, which encircle the |
whorl, have a strong projection both at the umbilical margin and at
the margin of the periphery, and a slight depression at the middle of
the periphery. The body-chamber began at a point where the shell
had a diameter of 295mm. and occupied fully three-fourths of the
last whorl. At the base of the body-chamber the thickness (or width)
and height of the whorl are about 135 mm. and 115 mm. respectively.
The aperture is not preserved. The details of the septal-suture are
unknown. On the earliest part of the outer whorl and immediately
in front of the aperture the periphery is broken and exposes the
siphuncle in the median line just beneath the surface in two places
(see fig. 2); in one place for a length of about 78 mm., and in the other
for a length of about 23 mm. ; here the diameter of the siphunele is
about 4°6 mm.
In a work by Emilien Dumas,! published (1875-6) after the
author’s death, an ammonoid from the Lower Aptian of the
department of Gard (France) is quoted (but not described) and
figured as Ammonitoceras ucetia,*? other cephalopods occurring at the
same horizon being very large examples of Ancyloceras matheronianum,
A. gigas, Nautilus radiatus, NV. plicatus, Ammonites stobieckit, and
Am. crassicostatus.
The genus Ammonitoceras was not described, but the following
extract from the notes of Emilien Dumas was given in a footnote by
the editor of the work (Lombard-Dumas): ‘‘Ce nouveau genre doit
étre placé entre les Ammonites et les Scaphites. Il se rapproche des
Ammonites par sa coquille enroulée en spirale réguliére dans un méme
plan et a tours en contact pendant la période embryonnaire et la
période daccroissement; mais a lage adulte, le dernier tour se
détache peu a peu des tours réguliers et sa projette en avant en
conservant toujours une forme arquée au lieu de se prolonger en ligne
droite comme dans les Scaphites.”’
In a note communicated to the Geological Society of France on the
19th December, 1910, Professor W. Kilian? noticed the occurrence of
a group of loosely-coiled ammonoids in the Aptian of France, of the
Caucasus, and of various other regions, in which the ornaments differ
both from those of Crioceras (sensu stricto) and of Ancyloceras (sensu
stricto) by the possession of only two rows of lateral tubercles

(instead of three), of which the outer one is situated towards the
middle of the lateral area, rather far from the median line of the
periphery and by the ribs crossing the peripheral area without
interruption.
For these forms, which according to Kilian may be considered as
having been derived from Acanthoplites, examples of this genus
occurring with them in the Aptian, Kilian uses the name Ammonitoceras
proposed by Dumas, and in it he includes the Ammonitoceras uceti@ of
Dumas from the Lower Aptian of Languedoc; Crioceras transcaspicum
described by Sintzov' from the Lower Gault of the Mangischlak
Peninsula on the eastern shore of the Caspian Sea, and which Kilian ?
states that he himself had also found in the Aptian of the Basses
Alpes; also the form noticed by Kilian* (under the name of
Ancyloceras ackermannt) and figured by Krenkel‘ (under Kilian’s
name of Aneyloceras ackermanne) from the Aptian of Delagoa Bay,
South-East Africa.
The present specimen seems to be clearly referable to this group of
forms and may be named Ammonitoceras tovilense, the trivial name
being suggested by the locality whence it came.

NOTE ON HELIX SCYTODES, PFR.
By G. K. Gupr, F.Z.S., ete.
Read 9th June, 1916.
Recentity, while working at some of the land shells in the collection
of the British Museum, I noticed two specimens of a helicoid which
I had not seen before, viz. Helix scytodes, Pfr.,1 from the Solomon
Islands. These were the type-specimens in the Cuming Collectiom.
I was immediately struck with their resemblance to two unnamed
shells which were acyuired by me some years ago with various other
shells at an auction sale, and actual comparison of the specimens
confirmed their identity.
The species was referred to Zrochomorpha by Pfeiffer* and by
Pilsbry,* but a careful examination of the shell convinced me that it
would more correctly be assigned to the genus Plectotropis, the
reflected outer and basal margins of the peristome, especially, being a
feature which would at once remove it from Zrochomorpha. Both the
type shells in the Cuming Collection, and those in my own, are devoid
of the periostracum and do not, consequently, show the scales which
are so characteristic of the genus Plectotropis, but traces of them can
be seen inside the umbilicus. The shell bears a general resemblance
to such species as P. winteriana, Pfr., P. tapeina, Bens., and
P. squarrosa, Gld.
No species of the genus Plectotropis, it is true, has been recorded
from the Solomon Islands, but Cuming is well known to have been
unreliable with his localities, and this may well be another instance
of a wrong habitat.
The species has been well figured by Reeve,‘ whose figure has been
copied by Tryon.*

NOTES.
ON THE OCCURRENCE OF HAULOTA FRUTICUM (MUtu.) In Kenr.
(Read 8th December, 1916.)—On 10th November, 1911, an example of
this species, collected at Penshurst, W. Kent, by the Rev. E. W. Bowell, was
exhibited (by A. S. K.) before this Society (Proc. Malac. Soc., vol. x, 1912,
p-1). It was then considered that the species could not be recognized as
a member of the British recent fauna, since only one stray example had
been found, but it was suggested that it might occur and be mistaken for
Theba cantiana (Mont.). Recently F. Hugh Gripper informed us that he
possessed some examples of a shell which he could not name, though
at the time of collecting he had thought they were the white form of
T. cantiana. An examination of the shells at once showed that these
shells were Hulota fruticum (Miill.). They were four in number, three
mature and one immature, and were collected in September, 1908, between
Dover and Lydden from a roadside hedge. There can now be no question
that. the species does live in Kent and has been confounded with Theba
cantiana (Mont.). The attention of collectors having now been called
to it, it will probably be found in other localities. The question arises
whether this species can be considered a survival from the Pleistocene,
or is a reintroduction. In the first place it is only known in a fossil
state in England from four localities, Barnwell and Grantchester
(Cambridgeshire), Stutton (Suffolk), and Ilford (Essex), and it has not
yet been detected in any of the Kentish Pleistocene beds. These four
deposits are all of the same age and form a well-marked horizon in the
Pleistocene. The species has not been found in any Holocene deposit.
in Kent. Hence it would appear that the species became extinct in
Pleistocene times, and these Kentish examples must be considered
a recent introduction. A.S. Kennarp & B. B. Woopwarp.
ON THE OCCURRENCE IN THE Britisu Istes or PALUDESTRINA MINUTA
(Torren). (Lead 8th December, 1916.)—About two years ago
Dr. A. C. Johansen called our attention to the existence of this species in
a living state at Blythburgh, Suffolk, examples having been given to him
by one of us (A. 8. K.). He pointed out that the species differed in its
anatomy from P. ventrosa (Mont.) and forwarded Danish examples.
We had hoped that he would have published the discovery himself, but
since he has not done so we think it is quite time the fact should be
recorded. Though greatly resembling P. ventrosa in its general appearance,
P. minuta may be distinguished by its smaller size and more regular
growth, the last whorl not being so inflated. We have now noted it.
in a recent state from Blythburgh, Southwold, and Lowestoft (Suffolk),
Woolwich (Kent), Strangford Lough and Killough (co. Down), and in
the Holocene from Littleport (Cambridgeshire), St. Ives (Huntingdonshire),
Deal (Kent), and Waterloo (Surrey). In all probability P. mdnuta is
a widely distributed form in these Islands.
Perhaps it may be of interest to add that we have lately received from
Mr. F. W. Harmer, through Mr. Alfred Bell, a gathering taken at Kaasjes-
water, near Zierikzee, at the mouth of the Scheldt, Baster’s locality for his
Turbo stagnalis. Baster’s description is too meagre and his figures too
weird to recognize his species, which has been assumed to be a synonym for
the wlve of Pennant. This gathering, however, consists almost exclusively
of Paludestrina minuta, the shells of which are coated, as Baster describes,
with a whitish limy deposit. A. S. Kennarp & B. B. Woopwarp.

HAS LYMNZA AN AURICULOID ANCESTRY,?
By Cuartes Heptey, F.L.S., ete.
Read 10th November, 1916.
Criricat study of fluviatile faunas has lately broken up the alliances
of former classifications and frequently ascribes to each smaller group
an independent origin from marine species.
Thus the Lymneide of Fischer’s Manual has been divided since
1883 into Lymneide, Planorbide, Ancylide, and Physide, while
Chilina is regarded by Dr. H. A. Pilsbry as having arisen in
South America from a marine parent. From what marine type did
Lymnea come ?
Judging from its radula, Mr. F. C. Baker proposed for Lymnaea
‘‘a descent from the Tectibranchiate stock of marine mollusks’’.!
It is now suggested that the Ellobiide may stand closer to Lymnea
than any Tectibranch.
Phytia ornata (Férussac). Upper and under view of the animal crawling.
In shell features the remarkable strongly-twisted pillar of Zymnea
may answer to the prominent columella folds so radical a character of
the Ellobiide. The animal of Zymnea is well known, but there are
few drawings, or descriptions from life, of the auriculoids. The
following notes which prompted the query at the head of this paper
are therefore advanced for comparison.
Phytia ornata, Férussac,? is abundant and widespread in South-East
Australia and Tasmania. Its habits are to associate with Rhodostoma,
Salinator, and Assemannia, in the Salicornia zone, that is just below
high-water level in sheltered estuarine swamps, either in the open or

under the shade of the Avicennia mangrove. At low tide the Phytia
crawls over the mud at a fair pace, and if placed in a vessel of
sea-water it soon creeps out and always moves steadily away from
the light.
The foot is small and narrow for the size of the shell. There is
no operculum. ‘The facial area is darker in colour and covered with
finer tubercles than the rest of the animal; it is marked off from the
foot by a groove on each side, When the animal is extended
the tentacles are planted well apart, but seem to spring from
contiguous bases when it is contracted. They are subcylindrical,
slightly tapering, blunt at the tips, contractile not evaginate. The
eyes are sunk within the substance of the tentacle at the inner base.
Near the tip of the muzzle are two white oblong marks that may
represent the smaller tentacles of the Helicide.
The muzzle is unusually broad, being as wide as the foot.
Sometimes it is emarginate in front and usually recurved at the
margins. The mouth is in the centre of a large labial disc. Between
this dise and the fore-part of the foot is a shallow pouch.
Here there seems to be a general correspondence to the pattern of
Lymnaea, the chief distinction being the longer and narrower tentacles
of Phytia.
Acclimatization from salt water to fresh is easy in warm
temperatures, but difficult in cold. So it was perhaps during the
warmer periods of the Kocene or Cretaceous that the rich Lymneid
fauna of the Northern Hemisphere arose from auriculoid sources.
ON SEXUAL CHARACTERS IN THE SHELL AND RADULA OF
POMATIAS ELEGANS (MULLER).
3y Dr. A. E. Boycorr, F.R.S., etc.
Read 10th November, 1916.
Some years since’ I examined the shells of a series of Pomatias elegans
from Ashtead in Surrey for sexual characters and found that the
females were longer and wider than the males, but not more tumid,
i.e. the ratio of length to breadth was the same in the two sexes.
In the present communication I give the results of the examination
of some 400 specimens, collected on about a hundred yards length of
chalky hedge bank in the parish of St. Stephen, near Aldenham,
in Hertfordshire, on 28th June and Ist July, 1916, when they were
crawling freely on the surface after rain. All specimens found
were taken without selection. The two lots were analysed separately,
but no significant difference was found in any respect and they are
treated below as forming one series.?
The shells were measured with sliding callipers to 0°1mm., the
length (altitude) being taken parallel to the axis of the shell and
the breadth (diameter) at right angles to the length. The fraction
altitude
diameter
course afford a complete description of the shells; with regard to
the shape of whorls, depth of suture, size and shape of mouth, and
the like, I can only say that by visual inspection I can detect no
difference between males and females,
In comparing males and females it is necessary in the first instance
to take only mature specimens, and as the criterion of maturity
the completion of the peristome has been used. There will obviously
be a certain number of specimens in which it is a matter of opinion
rather than of fact whether the peristome is complete or not; but
such specimens are few in number, and, noting also the texture
of the edge of the shell and the depth within the mouth where
the operculum makes a good fit, there does not seem to be much
danger of any substantial inconsistency in the determination of
maturity, at any rate within the same series of shells examined at
x 100 gives a measure of tumidity. These figures do not of

2 e.g. in the first lot males formed 54 per cent of 130 mature specimens, in the
second 61 per cent of 187, a difference easily compatible with the two lots
being random samples of the same series.
% I do not know whether sexual activity is restricted to individuals which are
mature by this standard; anatomically the sexual apparatus seems to be
pretty fully developed in the larger immature specimens (e.g. in many of
the males of 11-5mm. altitude). In species where the growth of the shell
reaches a definitive termination (e.g. Tachea), completion of the shell
seems to precede sexual action. The six pairs taken im cop. in the present
series were all mature.

(35 per cent) are larger than the largest male, the average female
being 1:2 mm. longer and 0‘8 mm. wider than the average male. If
anyone therefore wants to breed Pomatias it is probably safe to
assume that the largest shells are females and the smallest males;
about two-thirds might from their size be of either sex.
It would be a matter of much interest to determine whether there
is any size selection in mating. In the present series only six pairs
were taken 7 cop.; in each case the male was smaller than the
female :—

Taking the results as a whole, or dealing only with the groups
(13°5 and 14:0 mm. altitude) which contain a fair number of both
males and females not differing very grossly in size, there is no
evidence that there is any sexual difference in tumidity. The index
has a low variability,! and the evidence that it varies with size is
indefinite, though there is some suggestion that the larger shells are
relatively more slender.

III. Weteur or SHEtr.
The average weights of the shells with opercula (dried at 100° C.)
showed no difference between males and females except that due to
size.) In the 13:5 mm. group the sizes and weights are identical: in
the 14:0 mm. group the females (14°2 X 10-1) had larger shells than
the males (14:0X9°9). Hence we may conclude that there is no
sexual difference in shell thickness.

The bodies were used for various purposes; from 185 (112 males,
73 females) the radule were extracted by boiling with caustic soda
and mounted in Farrant’s solution. No sexual difference in the shape
or character of the teeth could be made out, and beyond three cases
with multicuspid centrals there seemed to be no gross variations; for
numerical examination the length of the radula and the number of
transverse rows of teeth were determined. The length is given in
arbitrary units, 12°8 of which equal 1 mm.

These figures show that the females have a larger radula than the
males but about the same number of transverse rows; in the males the
number of rows appears to increase as the shell becomes larger, while
in the females it remains the same or even becomes less. Whether
the difference in length is due to the larger size of the females is
uncertain without more ample data for males and females of equal
size. Relatively to the volume of the shell and the weight of the
body the female radula is obviously short and has few rows, but the
same is true of the larger males and females compared with smaller
individuals of the same sex. The ratio of the volume of the female
shell to that of the male is about 1380: 100.2 The average weights of
a series of bodies dried at 100° C. are given below, the general ratio
being 188: 100. On the whole, therefore, while the radula of the
females is slightly but clearly different from that of the males, it 1s
hardly legitimate to call it a sexual difference without clearer
exclusion of the size factor.

V. Sex or Immature SPECIMENS.
Those of the cmmature specimens which were 10 mm. or more in
altitude were examined for sex and gave 40 per cent males,® dis-
tributed as follows :—
1 It is obviously illegitimate to bring immature specimens into the comparison,
the radula being a feeding organ, and the amount of food required being
presumably quite different in growing and adult individuals.
2 i.e. assuming the shell is a regular cone with a base equal to the measured
diameter and a height equal to the measured altitude.
3 This does not satisfy the statistical test that there are really fewer males in
the immature than in the mature specimens (58 per cent).

ON THE OCCURRENCE IN ENGLAND OF HELICELLA NEGLECTA
(DRAP.).
By A. S. Kennan, F.G.S., and B. B. Woopwarp, F.L.S., ete.
With notes on the Anatomy by Dr. A. E. Boycorr, F.R.S., and on
the Radula by the Rev. E. W. Bowenr, M.A.
Read 8th December, 1916.
In September, 1915, several examples were found by one of us
(A.S. K.) on a grassy bank near Luddesdown, West Kent, of a Helicella
which was obviously new to our fauna. In the same month this year
two excursions were made to the localitv. On the first occasion
about six living examples and several dead shells were met with, but
on 17th September about thirty examples were collected, whilst
a number of immature specimens were left. On comparing our shells
with the large series of this genus in the Norman Collection in the
British Museum (Natural History) we were able to identify them as
Helicella neglecta (Drap.), and this has been confirmed by Mr. G. K.
Gude. Luddesdown is a small village about one mile south of Cobham,
and is situated on the Chalk. The bank where the species occurs is
about three-quarters of a mile south-west of Luddesdown church. It
is a grassy bank about six feet high, and is really a large gap in the
roadside hedge. It is a very remote spot, and we can offer no solution
as to how the species came to be established there. Search was made
in the neighbourhood to see if it occurred elsewhere, but so far it
appears to be restricted to this one locality. We, however, hope next
year to make a more extended search in the neighbourhood, for it is
extremely probable that this is not an isolated colony. The district
is not only a remote one, sparsely populated, but it is also famous for
the number of its botanical rarities. Helicella neglecta has been well
figured by Draparnaud (Hist. Nat. Moll. France, pl. vi, fig. [125] 13),
by Moquin-T'andon (Hist. Nat. Moll. France, pl. xviii, figs. 27-9),
and by Bourguignat (Moll. Algiers, pl. xxx, figs. 12-18).
According to Westerlund it lives in Southern France, Italy, Spain,
Greece, and Algiers, whilst Moquin-Tandon records it from Central
and Southern France. ‘he occurrence of this species in West Kent
thus affords an interesting analogy with the presence of //elicella
elegans (Gmel.) near Dover. In its habits it appears to resemble
H. gigaxti, Pfr., for nearly all the examples were high up on the
stems of grasses. In captivity it partakes freely of lettuce and carrot,
but is decidedly a shy species, retiring into its shell on slight
provocation.
ANATOMY.
The obvious anatomical distinction of Mr. Kennard’s specimens
from any known British Helzcell/a is the presence of a double dart-sac
lying on one side of the oviduct with a single dart, ¢fala having two
sacs one on each side with two darts, virgata, gigaxwi, and caperata
asingle sac. Apart from this the anatomy is similar to that of ¢tala
in its general features. The dart is of a simple slightly curved
154 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
acicular type. The second sac has slighter walls, and recalls the
accessory dartless sacs of Hygromia rufescens, fusca, and (from
Moquin-Tandon’s account) Helicella carascalensis.

The radula is 2°47mm. long and 0°96mm. wide. There are

externals. Ten typical admedians may be recognized, leaving twenty
externals; of the latter, the lateral ten or twelve have a well-marked
median cone. This is the condition which I have elsewhere described
as ‘‘ bifid mesocone”’, but in this case the accessory cone has more
the appearance of an appendage median to the mesocone. In my
figure of H. caperata (Proc. Malac. Soc., viii, p. 384) this feature is
more regularly represented than I have since found to be usual; it
is quite common to find an irregularly scolloped median margin to
the mesocone in that species. The general appearance of the unci
is shown in Fig, 2.
The maxilla is narrow, presenting no central increase of length.
It is provided with eight or nine ribs. Its width is about 1mm.

PATELLA VULGATA, LINNEZUS, AND ITS SO-CALLED VARIETY,
PATELLA DEPRESSA, PENNANT.
By the Rev. A. H. Cooxn, Se.D., F.Z.S.
Read 12th January, 1917.
Pennant, British Zoology, vol. iv, 8vo ed., 1777, p. 142, described his-
Patella depressa as a ‘‘ shell much depressed, the vertex approximating
nearly to one edge. More oblong than the former” [ vulgata }.
Forbes & Hanley, Hist. British Mollusca, vol. ii, p. 428, under the
name athletica, Bean, regard depressa on conchological grounds as
a true species, but, after mentioning that the two forms ‘inhabit
different levels, the vu/gata being always in the higher zone’’, add
the singular statement, ‘‘We have sought in vain for differences
between the structure of the tongue in this and the common species.”’
Jeffreys, Brit. Conch., vol. iii, p. 237, regards depressa, Penn., as
avar. of vulgata, and ‘‘ cannot find a single permanent character which
will serve to distinguish ”’ them or the var. ¢ntermedia, Knapp.
The authors of the List of British Marine Mollusca published by
the Conchological Society (Jowrn. Conch., vol. x, 1901, p. 16) appear
to have been of the same opinion, since they kept depressa as one of
the vars. of vulgata, but in their revised edition (1902) they treat them
as separate species.
If the radula of a specimen of vulgata, the shell of which measures
2 inches in length, be laid ont alongside the radula of a specimen of
depressa, whose shell is also 2 inches long, it will at once be noticed
that the radula of depressa is markedly shorter than that of vadgata,
probably by as much as 4 to 3 inch. Two other points will strike
the observer: the radula of depressa is much broader than that of
vulgata, and the nascent portion is relatively much shorter and
terminates more abruptly. Thus a radula of vulgata measuring
84:2 mm. long is ‘8 mm. broad, with perhaps 25 nascent and 190 adult
rows, while a radula of depressa 55°6 mm. long is 1°6 mm. broad, and
has 6-7 nascent and 112 adult rows.
If a long series of the two forms be taken, and the radule of shells
of equal length, from the same locality, examined, this difference
becomes more striking. Beginning with shells measuring 58°8 mm.
(the largest procurable of both species) and forming a series with
shells decreasing each time by an equal amount (1°6 mm.), we find
that in every case the radula of depressa is markedly shorter than
that of vulgata. Sometimes the amount of difference is so large as to
be startling; thus in the case of shells measuring 55°6 mm. the
radula of vulgata is 89 mm. long, that of depressa 47°8 mm.,
a difference of 41:2 mm., or more than 1} inches. In the case of
shells measuring 44°6 mm. the radula of vulgata (100°2 mm.) is more
than double the length of that of depressa (44°6 mm.). In. the
younger specimens the difference is just as marked. And if the
length of the radule of the whole series is added up, the average
length of a vulgata radula is found to be 63:6 mm., while that of
136 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
a depressa radula is 87°4 mm. Thesum of the whole of the differences
in length in favour of vu/gata is, in the twenty-nine specimens of the
series, 75°96 cm., or about 23 feet.

It must be remembered that the specimens examined are not
specially selected in order to exhibit differences of length in the
radula, They are simply, in each case, the first two specimens of
equal length which happened to come to hand on a certain beach in
South Devon.
In the teeth of the radule themselves certain small differences appear.
In both cases there are four uncini flanked on each side by laterals, the
innermost of which is armed, and not in the same plane with the rest.
In depressa the two interior uncini are much narrower than the two
external, the hooks being mounted on narrower bases than in vudgata.
This fact, which is observable in the nascent rows, becomes more
marked as growth proceeds. In vulgata, on the other hand, the two
interior uncini, although smaller than the other two, are not nearly
so unequal to them in breadth. Further, the serrations of the interior
lateral appear to be much more deeply cut in vulgata than in depressa.
The sum of all these observations seems to tend decisively to the
conclusion that in vulgata and depressa we have two quite distinct
species of British limpets. It is my impression, which I have not yet
had time to verify, that vulgata is a northern, depressa a southern

form, and that while the northern limit of the distribution of vulgata
is about the latitude of the Lofoden Islands, that of depressa is very
much further south.
It should be made clear that the statement of Forbes & Hanley—
the two forms ‘‘ inhabit different levels, the vudgata being always in
the higher zone ’’—does not represent the facts accurately. P. vulgata,
as is well known, lives from near high-water mark to the extreme of
low-water. LP. depressa, on the other hand, is seldom found till near
low-water mark, where, so far as my experience goes, vulgata and
depressa occur abundantly on the same masses of rock. ‘This fact
further strengthens the case for their specific difference.
*,* Since the foregoing paper was read, our Editor informs me that
it is stated in Woodward’s Manual, 1st ed., p. 451, that ‘*‘ Mr. Wilton
has ascertained that Patella athletica may be distinguished from the
common limpet of our coast by its teeth”’. He further tells me that
in his uncle’s interleaved working copy of the Manual, now in his
possession, he finds the following manuscript note: ‘‘ Patella athletica:
dental canal not much longer than the shell (scarcely half as long as
in P. vulgata): teeth closer together than in P. vulgata; more
massive and with shorter cusps; the difference is greater in the
imperfectly developed teeth near the further extremity of the canal.”

NOTE ON THE TYPE-SPECIMEN OF CRIOCERATITES
BOWERBANKII, J. DE C. SOWERBY.!
By G. C. Crick, F.G.S., F.Z.S.
Read 12th January, 1917.
PLATE VII.
Tue type-specimen of Crioceratites bowerbankii, formerly in the
Bowerbank Collection, now forms part of the British Museum
collection [ Brit. Mus. No. 46474]. The present writer’s attention was
directed to it recently in connexion with the description? of an
ammonoid, Ammonitoceras tovilense, from the Lower Greensand ( Aptian)
of Kent, and two or three features about the specimen that had not
hitherto been recorded seem to deserve notice.
Sowerby’s*® description of the fossil was communicated to the
Geological Society of London in a letter which was read on
March 8th, 1837. In his letter Sowerby writes: ‘‘'The recent
discovery in the Isle of Wight, by Mr. Bowerbank, of a fossil shell
resembling Ammonites, but differing essentially from that genus, and
of a magnificent Scaphites, appears to me of sufficient importance to
be laid before the Geological Society; I have, therefore, drawn up the
following descriptions, accompanied by reduced figures of the fossils.
ply sexxiv.”
His description of Crioceratites bowerbankit is as follows: ‘‘ The
gigantic species from the Isle of Wight I shall name, after its
discoverer, Crioceratites bowerbankit, pl. xxxvi, fig. 1. Spec. Char.—
Whorls about four, slightly flattened on their sides, and nearly close ;
the inner one ornamented with numerous radiating furrows, which,
gradually disappearing upon the outer whorl, are replaced by eight
or ten thick, arched cost, extending completely across the whorl,
and largest and most elevated towards the thinly edged, transversely
oblong aperture.
‘‘The septa are rather distant, terminating where the coste begin
to enlarge. There is generally a short rib almost close to the
aperture, and in one specimen I have noticed an additional short
rib between the two long ones which precede the termination. In an
individual sixteen inches wide, the septa are one inch and a half apart.
‘The fossil occurs in the lower green sand on the south coast of
the Isle of Wight.”
The type-specimen is very well represented in Sowerby’s
figure, the enormous enlargement of the ribs on the body-chamber
being well shown. Of these ribs, and counting from the aperture,
the two largest are the third and fifth, the fourth is a trifle

thicker but not quite so prominent. The last two, however, show
a considerable diminution in size. About 40mm. in front of the last
complete rib there is another obscure rib, most apparent near the
periphery, and about 20 mm. in front of this a portion of the peristome
is visible. The peristome was plain, and in the fossil, which it must
be remembered is an internal cast, there are several fairly-coarse
lines of growth immediately posterior and parallel to it.
Not only are the ornaments much more feeble, but the body- —
chamber itself is very much reduced in front of the third (counting
from the aperture) large rib. True the (morphological) left side of
the fossil is abraded, but the fossil does not appear here to be either
distorted or crushed. This condition of the anterior end of the body-
chamber is evidently a senile character and indicates the extremely
feeble condition of the animal and its approaching death.
Although the rough surface of the specimen, which is an internal
cast, is not favourable for the preservation of delicate lines, there is
what appears to be an obscure indication of one of the muscle-scars.
When complete the scar seems to have been an oval area truncated
posteriorly, approximately 45mm. long and 40mm. wide, but only
its anterior and inner boundaries are preserved as an obscure
impressed line. Commencing on the umbilical margin at a point
half-way between the sixth and seventh (counting from the aperture)
ribs the line passes forward and inward over the margin to within
about 30 mm. of the suture of the shell, it then curves backward still
passing inward until at about 28 mm. from its most anterior part it is
only 10mm. from the suture of the shell, then curving slowly outward
it can be traced nearly as far as the last septal-suture.

A REVISION OF THE TURRIDH (PLEUROTOMID) OCCURRING IN
THE PERSIAN GULF, GULF OF OMAN, AND NORTH ARABIAN
SEA, AS EVIDENCED MOSTLY THROUGH THE RESULTS OF
DREDGINGS CARRIED OUT BY MR. F. W. TOWNSEND, 1898-1914.

PLATES VIII-X.
Tur comprehensive study of the marine mollusean fauna of the
Persian Gulf and its contiguous seas is of comparatively recent date,
hardly any steps having been taken to classify or enumerate the
members of the richest family occurring within that area, until 1875,
when Messrs. Geoffrey and Hugh Nevill published an account of
‘“New Marine Mollusca from the Indian Ocean, mostly Pleuro-
tomide’’.! In this treatise about twenty-five species are named, but
many of them occur beyond our assigned limits. These were all well
described, but only fairly figured on the whole. '‘I'wo years later, in
1877, Mr. Edgar Smith began his ‘‘ Diagnosis of new species of
Pleurotomide”’ in the British Museum,’ and a series of papers
followed, which were not completed till October, 1888. Very
unfortunately, but owing to no fault of the author, who always
spoke regretfully to me of the circumstances, none of them were
figured. Over 160 species were diagnosed, and the types noted.
During the past five or six years a few of them have been illustrated,
either by Mr. C. Hedley * or myself,* but only a very few, and there
can be no concealing of the fact that a great stumbling-block to the
student has been occasioned by this omission. Many times I had
discussed this question with Mr. Smith, and had resolved to delineate
all that came from this particular province, from the actual types,
and I find that thirty-five (or one-fifth of the total) of his species can
be included.
I therefore venture to offer now the three plates accompanying
this paper, as some slight memorial of one to whom molluscan science
owes so much, and whose unvarying kindness, attention, and readiness
to assist in every possible way those who asked his advice and help,
so endeared the name of Edgar Albert Smith to all.
To discover these types I have been several times through the
amassed stores of this family in the cases and drawers of the cabinets
at the Museum, and only in two instances have I so far failed to find
the objects of my search.

I may add that more than 180 species are treated of in this paper,
and one-half of them have been described as new, mainly from
Mr. Townsend’s collections. The typesare allin the British Museum.
The Turride (Bolten’s name TZurris, 1798, antedating Lamarck’s
Pleurotoma, 1799) are certainly among the most, if not the most,
attractive of all the genera of marine mollusca, and at the same time
the most difficult to classify properly. This fact really adds incentive
to their study, coupled with their infinite variety of contour, the
many rare and abysmal forms, and the certainty of additions occurring —
to the family whenever new ground—or rather seas—are examined.
Yet, so far, no student has made this one group his life-work.
I am convinced that the fossil forms (mostly Tertiary) should be
studied part passu with the recent, before any satisfactory headway
towards the much-needed accurate classification can possibly be
reached.
Mr. 'I’. L. Casey’ has attempted this with some measure of success
as regards the larger forms, both recent and fossil, though he has
evidently mainly worked out the species of the last named in the
United States far more completely than those of the Old World.
He creates various new genera for the more pronounced species.of
considerable size, but notes his inability ‘‘ after long and patient
study of rather large material to devise a system of characters to
serve for the definition of the subtribal groups” he includes under
the collective term Daphnellini.
For the sake of convenience, an alphabetical sequence has been
adopted in the enumeration of all the following species under what
I assume to be their proper genera, but I have endeavoured, in the
remarks that accompany each, to name their most likely affinities.
A large proportion of the forms from this region are endemic, so
far as is known, and certain of them are very conspicuous for beauty
of contour or coloration. In the first category might be placed such
species as Zurris invicta, Mungilia Townsend, Clavatula navarchus,
and Drillia tasconium; in the second, Drillia resplendens, D. persica
var. jacintha, and Cythara hyperealles. Many Daphnelle and Pleuro-
tomelle, the ten species of the latter not yet being known elsewhere,
are of exquisite and most delicate design, pure white, and abysmal in
distribution. It has been found necessary to institute a sub-genus
(Diaugasma) for the curious Daphnella epicharta, M. & St., and another
( Veprecula) for a series of deep-water Clathurelle with nuclear and
other peculiarities. Doubtless, as hinted by Mr. Casey, the vast
genus Mangilia will be subdivided when the relations of the species
are better known; indeed, I believe Mr. Iredale, to whom I am very
greatly indebted for many useful hints in nomenclature, already has
the matter in hand.
It now only remains for me to thank also Mr. J. R. le Brockton
Tomlin for considerable assistance; and Mr. R. Standen, with whom
I collaborated in the first enumeration of this Family,’ as far as the

Gulf was concerned; Mr. Townsend, as I have often had occasion
to observe, in the care exercised in the preservation of the specimens
collected, and in the labelling of exact localities, as well as in the
selection of good dredging stations, exceeded most, if not all his
forerunners, and to him I feel extremely grateful, now, as ever.
Lastly, to Miss Gertrude M. Woodward I must express my especial
gratitude for the admirable illustrations delineated with such
consummate accuracy.

I. Bombay.
A variable species, extreme forms being happily figured by Reeve.
Distributed over the Eastern 'l'ropics very widely, ranging from the
Red Sea to Australia and Polynesia, and as far north as Japan,
I do not agree with Tryon (Man. Conch., vol. vi, 1884, p. 165) that
hastula, Reeve (Conch. Icon., vol. i, 1843, pl. xvii, f. 139), is the
young of this species.
From the Cargados Isles came interesting albino specimens (Stanley
Gardiner Expedition).1 These are probably the PJ. buelowi, Sowb., and
have the appearance of having been dredged at a considerable depth.
I may add that for this species and acuta, Bolt. (as well as
leucotropis, Ad. & Ryvye., srekeli, Weink., unedo, Vil., and virgo,
Lam.), Dr. Thomas L. Casey proposed a new genus, Lophiotoma, laying
stress upon the stouter form, abbreviate, with straighter beak, more
acutely elevated and less close-set spiral carina, and with deep anal
sinus formed centrally ov, and not behind, the peripheral keel, the
latter being more strongly elevated and usually sub-duplex.
Possessing all these species, I have closely compared their
structure with those few still allowed a place in the typical genus
Turris, the result being that I prefer to consider them all so
closely allied that it seems disadvantageous to separate them even
subgenerically. ‘The nepionic whorls are confessedly identical; it
is simply a question of the carine being more pronounced in such
a species as acuta, for instance; the same character of marking or
painting is to be found, and to a great extent the same build and
contour generally.

102 fathoms, also west of the Malabar Coast at 295-360 fathoms, from
mud and sand. Wehad hoped to have found it among Mr. Townsend’s
collections.
Many other large abysmal species were found by the IJn-
vestigator, but mostly in the Bay of Bengal, or off Ceylon, and the
Malabar Coast, outside our limits. Most, if not all of them, have
been figured by Messrs. Alcock, Annandale, MacGilchrist, and others

P. fusca, H. & J., we consider synonymous; the dark form

The distribution is extended over the eastern tropics from the Red
Sea to Australia. It does not, however, occur in Hidalgo’s
Philippine Catalogue. Hedley, in his Queensland List, separates
“« Pleurotoma”’ gemmata, Hinds, and ‘‘ Drillia”’ fusca, H. & J., and

It is merged by Tryon (Man. Conch., vi, pp. 171, 172) with Hinds’
species, but this evidently only on surmise, since he had never beheld
acutigemmata. We have it also from the Andaman Islands (Booley).!

It is therefore in all probability widely distributed over the whole

form; but the name had been previously employed, by Mighels and

A small white shell, with mouth decidedly buccinoid. Nearly all
the specimens seen are imperfect as regards the nuclear whorls. The
shell is closely, spirally ridged. here are many differences of opinion
among those I have consulted as to the proper status of this species,
which may be the young of a Zritonidea or allied genus. At the
same time it seems to possess some Pleurotomoid characters, but, until
better material is obtained, I fear no quite satisfactory conclusions
can be drawn.
Judging by the figure, it resembles in form, shape of aperture,
and general sculpture, Daphnella (Teres) mimica, Sowb.,'’ from

An elegant tornate species, with produced canal, and spiral ribbing
somewhat similar to that of Pl. nivea, Phil., but more regular.
White, tinted yellowish around the upper double carine of each
whorl; just below the sutures these carine are spirally deeply
punctulate, an item omitted in the original description. These
additional notes are taken from the specimen noted as from the cable,
west of Bombay. The dimensions of this are long. 20, lat.6mm. As
regards the nuclear whorls, the first two are vitreous, globular,
smooth, and shining, the two next, also vitreous, but spirally
nodulous.

This may, perhaps, stand on its own merits, as distinct from

in size, also in less prominent spiral ribbing, the characteristics of
which, however, are almost identical, and, above all, the chestnut zigzag
longitudinal markings down the whorls, the same colour permeating
the sutural region in more or less density. My largest example only
measures 17mm. in length, while nvea attains 25 mm. or more.
I have lately received characteristic Japanese specimens, collected by
Hirase. The chestnut painting is distinct and peculiar, in zigzag
longitudinal flames on white ground.

somewhat after the manner of Plewrotoma lobata, Sowerby.’ The largest
example, unfortunately with imperfect outer lip, measures longi-
tudinally 26 mm., is whitish, the spiral raised ridge just below the
suture of each whorl is pronounced, with ribs thick, straight, and
somewhat oblique on the last whorl only. In a smaller, and more
perfect specimen, the labral lobe projects almost at right angles to
the slightly produced canal. he aperture is milky-white within,
whorls in young specimens very closely spirally striate, slight chestnut
maculations very sparsely cover the surface in certain examples, in
others the coloration is simple, dead white or palest ochreous.

seas and a deep-water form. The distribution of D. flavidulais wide,
including Hong-Kong and China proper. But the largest example in
my collection is from the northern shore of the Red Sea, that was
picked up on a sandy beach many years ago by my cousin, the

latisinuata’ of Smith. I possess a co-type of this “ex auctore”’, and
at the suggestion of Mr. Le Brockton Tomlin, have well compared it
with a large and variable series of flavidula in my _ collection.
Mr. Smith admits the near alliance of the two species, and lays stress
on ‘‘the upper half of each whorl being nearly smooth, as_ the
plications extend scarcely beyond the central large spiral liration
which marks the angulations of the whorls’. This may be true as
regards the type, but there are several intermediates, and I think we
may consider flavidula as a protean species, and what may be called
the form /atisinuata does likewise occur in the Persian Gulf.

The prolonged canal serves slightly to distinguish it, and its pale,
colourless whorls; the sinus, too, is remarkably patent, but it is not
easy to characterize its qualities for purpose of differentiation. We
would refer to the author’s description. The type now figured came
from New Guinea. But few examples have been yet found in the

This is a plentiful species, and appears to be more ‘‘ inconstant”’

almost white to chocolate-brown. Sometimes the tubercles, spirally
arranged below the sutures, are shining white, the rest of the shell
being darker, but this is a rare variety. So nearly akin is this
species to certain forms of pyramidula, Reeve, that I expect they will
be united some day, if not immediately.

magnified scale, there can be little doubt that these are one and the
selfsame species. We have figured the actual type of disjecta from
the National Collection. Mr. Smith lays stress upon the upper ribs
in this species being always nodulous, and thus being capable of
being distinguished from the very nearly allied persica at sight. To
my mind, nevertheless, these species are almost too near, and mainly

The specimens are bright brownish-pink, very shining. It may not
perhaps have attained quite full growth, although the outer lip is
fairly formed. It is quite distinct from granatella, Melv. A much

A plum-coloured shell, larger in all its parts than tnconstans, Sm.,
being of the same alliance. The largest specimen I have seen
measures long. 18 mm. as against 8°50 mm. in tnconstans. Indeed,
the type of the latter only measures 5 mm.
The nearest ally seems D. radula, Hinds (Moll. Voy. Sulphur,
1844, p. 16, pl. v, f. 9), from the Straits of Malacca and Australia
(Queensland), well figured by Reeve (Conch. Icon., pl. xxv, f. 223).
The nodules in radula are shining white, contrasting with the
dark-brown body-colour. I have examples from the Lombe Taylor
Collection. It is larger (long. 20 mm.) and coarser in its sculpture
than prunulum, the largest specimen of which that we have seen comes
from Koweit, and measures long. 15 mm. The noduled riblets are
here almost twice the number of those obtaining inradula. Notwith-
standing this, doubtless znconstans, lithoria, prunulum, pyramidula,
and radula have many characters in common, and probably spring from
a common ancestor.

spiral nodules so conspicuous a feature in Smith’s species are hardly
present in its ally, pyramidula being, to quote the words in the
original description, ‘‘ pyramidally elongated, very closely latticed
with minute longitudinal and transverse ridges.” ‘The second and
third nuclear whorls are carinate.

occurred off Muscat. A very bright and beautiful species, one of the

genus as lucida, Nevill, and persica, Sm., the variety jacintha of which,
just described above, almost exceeds resplendens, if possible, in select

D. pallida, Sowb., of which I possess a beautiful example from
Central American shores, is also comparable, but it is not only
smaller, whilst the costze of the body-whorl are oblique, and the form
more attenuate. D. tasconium is very liable to sea-breaks and slight

Mr. Iredale assures me it is antagonistic to the laws of priority to
continue using the name ‘‘ Clavus”’ subgenerically, it having been
published by Montfort twenty-eight years earlier for a different
group than the accepted generic ‘‘ Drillia”’, Gray, 1838. Accordingly,
a new cognomen being necessary, I venture to propose Zylotia, which,
being derived from tvAos, a nail or club, has the same meaning as
Clavus. The type appears to be canteularis, Bolt.=auriculifera, Lam.

the former of them at the base of the body-whorl is distinctive ; all
the genuine specimens of this in my collection are so coloured. It is
a narrower shell, too, than Hedley’s new species. I doubt the
occurrence of true dzcolor in these seas, as has been reported (Proc.

Live albino shells dredged off the above locality constitute a well-
marked colour variety.
The largest examples of this interesting species, surely worthy of
a more complimentary cognomen, come from the Linjah Anchorage,
and measure long. 14mm. It is of extended range. Hinds
described the type from New Guinea and the Straits of Malacca in
5-18 fathoms, mud. Reeve! compares it with argillacea, also of
Hinds, and from the same locality (Malacca). Judging from the
figure it would seem almost identical. ‘lhe smallest examples of this —
species that have come under my notice measure long. 9 mm., and
are in my possession, labelled ‘‘From the Lombe Taylor Coll.”
Under the name Clathurella spurca, Hidalgo admits it to his
Philippine Islands list, and Hedley, as Glyphostoma spurcum, from
Queensland.

I would suggest Clathurina, taking as the type Cl. foraminata
(Reeve).

origins do not suggest any seasonal or local influence; eight of
fourteen spring specimens and three of six collected towards autumn
had no male organs. It is not that the male organs were rudimentary
or ill-developed, they were not there at all, and the lower genitals
were reduced to an oviduct and spermatheca, not different in any
obvious way from those present in specimens with the full complement
of male organs.! On the other hand, these individuals were not
females, since in each one of the twenty specimens, whether the penis
was present or not, plenty of eggs and spermatozoa were found in the
hermaphrodite gland and duct.?, Such an arrangement is remarkable
and is, I think, unknown among the larger snails whose viscera are
familiar.

The condition in these eleven specimens was in short similar to
that found uniformly in twenty damellata,‘ and its interpretation is
equally difficult. They might be functionally only females; the
presence of abundant spermatozoa is against this, though it is well
known that in comparatively highly developed animals (e.g. frogs)
the sexual glands may produce a certain number of gonads in-
appropriate to the sex of the individual. They might be self-
fertilizing hermaphrodites; such is unusual, but is known to occur
under stress of circumstances in a certain number of pulmonates,‘
and is a general possibility. They might be functionally both male
and female, it being pretty clear that the vagina could function as an
intromittent organ. They might be cyclically unisexual, though
I think that any question of proterandry or proterogyny is excluded
by the absence, rather than the presence in an atrophied condition,
of the male organs, and by the abundance of spermatozoa. They
might be abnormal abortive individuals, sexually impotent, a sort of
1 The specialized segment of the wall of the glandular oviduct which is
associated with the origin of the vas deferens was present, though not
perhaps so fully developed as in those individuals in which that duct was
found, and in some cases a short tag of vas deferens arising from it and
soon ending blindly below.
2 The spermatozoa were mostly in the duct. In one aphallic specimen,
a mass of spermatozoa extended from the upper part of the spermoviduct
to near the genital orifice, and there were a few in the spermatheca, but it
cannot of course be known where they came from.
3 Tam much indebted to Mr. J. A. Hargreaves for these specimens.

molluscan free-martin; it is difficult on this hypothesis to explain
the normal structure of such organs as are present or the frequency
of the condition.
The only anatomical point which I have observed which might
help to a decision between these various possibilities is that the
glandular organ with granular cells in connection with the spermoyi-
duct, which is known as the prostate, was not found where the penis
was absent. This suggests, though quite indefinitely, that these
individuals were not functional males.’ f
Hermaphroditism is often associated with an indifferent capacity
for locomotion, and itis a clear advantage to snails that, when two do
happen to meet, both should be able to produce spermatozoa as well
as eggs. Hence arises another consideration which may have to do
with the absence of male organs. Large snails walk faster than
small snails, and with very small species the rate of progression may
become so slow that the chance of two individuals meeting becomes
so trivial that it is not worth while to maintain an effective male
copulatory apparatus. Locomotion becomes so slow that the habit
of self-fertilization is added to the hermaphrodite structure. That
dispersion of the members of a family from their birthplace is limited
in the same way is no substantial objection to this view when we
consider that the time devoted to sexual confluence is very small
compared to that spent in wandering in search of food. It is perhaps
also noteworthy that aculeata is not a gregarious species; the area
in which it occurs may be circumscribed rather closely by environ-
mental conditions, but the individuals generally occur in groups of
one each, and the density of the population is low; it is not an
‘abundant’? species as is often, e.g. Carychium minimum, in the
same habitats. As far as I know, ldamellata has much the same
habits, though it is perhaps more abundant where it occurs. In
some other small snails gregarious habits render congress more
likely, e.g. Pyramidula rupestris, Pupa umbilicata, Vertigo spp., and
in these a penis is found, though whether in all specimens I do not
know; male organs are also described in Carychium.
On the whole I incline to the speculative explanation that the
aphallic state is due to the simplification of structure which is
necessarily associated with diminution in absolute size, that an
animal cares more for what it does than for the apparatus by which
it does it, and that both phallic and aphallic forms are alike
hermaphrodite and reproductive. ‘The view that the possibilities of
organic action are limited by narrow morphological boundaries has
been productive enough along the line of phyletic speculation, but
1 An organ of similar histological constitution is present in lamellata, but in
connection with the lower part of the glandular oviduct, and hence
possibly different in character; acuwleata has nothing like it in the
lamellata position.
2 I am referring especially to dead leaves, particularly beech leaves, in woods.
In the few specimens of Punctum pygmeum from the same habitat which
have been examined, no penis has been found.

it is essentially mechanistic in character, and fails to take into
account the demonstrated capacity of living organisms to achieve
their ends by self-regulated means. We should not, in other words,
be too quick to assume that an aculeata is at any very grave dis-
advantage in maintaining its individuality and reproducing its kind
because it has no penis; the majority, at any rate, of damedlata have
abandoned that organ in favour of the roominess afforded by its
absence, and reduced their genitalia to the simplest essentials.

THE RADULA OF THE GENUS COMINELLA, H..& A. ADAMS.
By the Rev. A. H. Cooxg, Sc.D., F.Z.S.
Read 9th March, 1917.
Tue genus Cominella appears to occur in two principal nuclei of
geographical distribution, (1) the Cape, (2) South Australia, T'asmania,
and New Zealand. It has not been reported from South American
waters, where, in the extreme south, it appears to be replaced by
a considerable development of the genus Huthria, and, though there is
an outlying species ( fucata, A. Ad.) said, on inconsiderable authority,
to come from Japan,’ it has not been recorded from Western North
America. The Philippines is another doubtful locality for another
doubtful species (crocea, A. Ad.),
Kobelt, in 1878, enumerated? 34 species in all: Cape 12, New
Zealand 9, Chatham Is. 1, Port Western 1, South Australia 4,
Tasmania 1, Swan R. 1, Darnley Is. 1, doubtful localities 4. Tryon’s
sweeping methods* reduced these to about 20. G. B. Sowerby
listed‘ 17 species in all from South Africa, the generic position of
4 of which was doubtful. Paul Bartsch, in 1915, added® 4 more
species to this list, making 21in all. H. Suter® recognizes 10 species
from New Zealand and the outlying island groups, from the Kermadecs
to Campbell Is., two at least of which (costata, Quoy, lincolata, Lam.)
are also found in Australian waters.’
For the purposes of the present paper the radule of the following

SPECIAL CHARACTERISLICS OF THE RHACHIDIAN TOOTH IN THE VARIOUS
SPECIES.
1. adelaidensis.—Cusps rather narrow and close together. The
lines of the base are somewhat square, and the two lower prolongations
(hereafter called the wings) of the base are thickly rounded.
2. alveolata.—Cusps rather short, further apart than in adelaidensis,
base-lines not quite so square, wings short, rounded at the ends.
3. costata.A—Cusps small, narrow, very close together, wings of
the base greatly prolonged, narrowed at their lower ends, lines of the
base rounded, not squared.
4. filicea.—Cusps short, somewhat elevated above the upper base-
line, wings of the base prolonged a little, but not nearly so much as
in costata, angles of base-lines rounded.
5. huttoni.°—YVhere is scarcely any recognizable difference between
this species and dineolata.
6. dineolata.—Closely corresponds to alveolata both in the form of
cusps and shape of base.
7. lurida.s—Cusps short, equal in length, rather close together,
wings of base decidedly prolonged, but not so much as in costata.
8. maculata.2—Cusps prominent, close together, base rounded above,
wings short and rounded.
9. maculosa.—Cusps markedly triangular in shape, well apart from
one another, base as in maculata.
10. virgata.—Cusps sharp and small, separate from one another,
base not prolonged into wings, rather angulate above.
The species of the whole group he remarkably close together, and
the one markedly characteristic difference is the prolongation of the
wings in costata, filicea, and lurida. The shape of the laterals is
constant, and exhibits scarcely any appreciable difference in the
various species.
1 «+ means that a few rows at one or other end of the specimen were missing.

COOKE: ON THE RADULA OF COMINELLA. 229
II. The Care croup of species is distinguished by two very marked
types of radula.
(a) Rhachidian tooth rather bluntly tricuspid, base deep and
squarish, arched below, no wings; laterals tricuspid, the smaller
inner cusp in the Austro-Neozealanian group being replaced by a
two-denticled cusp, simple, deeply cut.
(6) Rhachidian tooth bluntly long oblong, base slightly arched
below, angled in front, set with a number (4-7) of small sharp
denticles, laterals quadricuspid, large, cusps boldly curved, the three
inner forming a group, of which the central is much the largest.
I have counted in
delalandii 112 + rows of teeth, Jimbosa 116 rows of teeth.
elongata 109 , porcata 116 %
lagenaria 120 5 tigrina 95+ *
SPECIAL FEATURES OF THE VARIOUS SPECIES.
Group (a).
elongata.—Cusps of the rhachidian tooth not much elevated above
the upper edge of the base; base deep, pinched in at the sides and
slightly arched below; lateral tricuspid, the two inner cusps very
close together, deeply cut.
tigrina.—Cusps of the rhachidian tooth considerably elevated
above the upper edge of the base, the two outer cusps set at an angle
with the central; base markedly angulated at its upper edge, pinched
at the sides, deeply arched below; lateral tricuspid, the two inner
cusps further away from another than in elongata, not so deeply cut.
Group (8).
delalandit,—Rhachidian tooth with four denticles; base angulated
at the upper edge, slightly arched below; lateral showing no sign of
denticulation on any of the cusps, exterior of the three interior cusps
large, central very large, curved over the interior cusp, which is very
small, not serrated.
lagenaria.—Rhachidian tooth with seven denticles; upper edge of
base slightly produced at the ends, base considerably arched; in the
laterals the interior cusp shows signs of serrations on the outer edge,
the exterior cusp of the group of three is very small, curiously curved
inward.
limbosa.—Rhachidian tooth with six denticles; base squarely
oblong, slightly rounded at upper angles, lower edge scarcely arched ;
both the exterior and interior cusps of the group of three large, blunt,
the interior slightly serrated on the inner edge.
porcata.—Denticles of the rhachidian tooth six in number, rather
larger than in the other species; base with the upper angles rounded,
very slightly arched below; interior cusp of the group of three very
large, with faint traces of serration on the inner side, exterior cusp of
this group small and narrow. In some of the laterals there are clear
traces of a supplementary denticle or knob, between the tricuspid
@ inner tooth and the great outer cusp.

The species of Cominella whose radula has been examined fall
into three very well-marked groups, of which (1) is confined to
Australia and New Zealand while (2) and (3) are characteristic of the
Cape. The radula of the species comprised in Group 1 are singularly
alike in the shape of their teeth, both rhachidian and lateral, while
those of the species falling under (2) and (3) manifest considerable
individual differences.
COOKE: A COLONY OF NUCELLA LAPILLUS. 231
Group 1 exhibits teeth of a very simple character. Group 2 is
closely allied to Group 1, the most marked point of contrast being
the bifid cusp in the lateral. Group 3 is by far the most specialized
as regards radula, and, while preserving a certain tie of kinship,
stands well apart from the other two, both as regards shape and
denticulation of the rhachidian and in the elaboration of the cusps of
the laterals.
It is hoped that the facts now brought together may be of use, as _
throwing light on the general inter-affinities of the group as a whole,
and possibly on the vexed question of distinction of species.

A COLONY OF NUCELLA (OLIM PURPURA) LAPILLUS (LINN.)
WITH OPERCULUM MALFORMED OR ABSENT.
By the Rev. A. H. Cooxg, Sc.D., F.Z.S.
Read 9th March, 1917.
Visirine Lydstep (a few miles west of Tenby) in August, 1915, at
a very low tide, I took a living specimen of J. lapillus off the face
of the cliff, and observed that it had no operculum. Thinking that
perhaps the act of pulling the specimen off the rock had torn the
operculum away, I examined further specimens, with the result
that it appeared that this particular colony of Nucella were suffering,
to a considerable extent, from malformation of the organ.
Of 121 specimens examined,
(1) The operculum was more or less perfect in 54.
(2) i 55 decidedly imperfect in 56.
(3) te Si absent altogether in 11.
In class 2 the imperfection was not always of the same nature.
Sometimes the operculum was considerably reduced in size, so that,
when the animal was withdrawn, only a portion of the aperture was
covered. Occasionally the operculum was perfect as regards size,
but was thin, and of a very light horn colour, almost white, instead
232 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
of dark brown or black. Sometimes the forward edge was ragged
and untrimmed, instead of being sharp and clearly rounded.
In the eases where the oper culum was absent altogether, the area
left uncovered was not smooth, as it is when one peels off an
operculum from a perfect specimen. The surface where the
operculum should have been was contracted, wrinkled, and raised
into knotty humps, as if the animal were making some effort to
compensate for such protection as is afforded by the operculum, by
a thickening of the integument in that area.
What particular purpose is served by the operculum in this and
many other kindred species of Mollusca is not quite clear, since the
animal remains normally adherent to the rock by its foot, on some
point on the upper surface of whose hinder portion the operculum is
carried. It is only when the animal becomes detached from its
position that the operculum closes the mouth of the shell, and it is
clear that to become detached is the last thing which is desirable for
species which normally live adherent; in many cases they must be
unable to regain their position.
In the present case it seemed probable that overcrowding and
under-feeding were the cause of the defects of the Nucella. In size
the shell was not more stunted than specimens to be found on almost
any exposed coast. But there must have been thousands of them on
the perpendicular cliffs at Lydstep, clinging closely together, and
with no food but barnacles and an occasional limpet. Under such
circumstances it is not surprising that signs of decadence should
manifest themselves.
It never seems possible to predict what particular form of decadence
will result from any given diminution of the optimum of environment.
The only case at all parallel to this, as far as Vucella is concerned,
occurred in a group of J. lapillus found living at Minehead. Near
the harbour, where the water is specially muddy, and the holding
ground foul with decayed wood and lumps of rotten clay, specimens
occur whose shells are riddled with some boring worm, with the
result that they are decollate, the suture often deeply pitted, and
the base of the columella and the outer lip eaten away and ragged.
so that the whole shell presents a most forlorn and wretched
appearance. Yet, in every case examined, the operculum was
perfectly normal in shape, size, colour, and thickness.
THE RADULA OF THE GENUS HUTHRIA, GRAY.
By the Rev. A. H. Cooxn, Se.D., F.Z.8.
Read 13th April, 1917.
Tue generic name Huthria appears to cover a variety of species which
in certain points differ widely from one another. Founded by Gray
in 1850 (Fig. Moll. Anim., No. 67), its type is the Mediterranean
cornea, L. Kobelt catalogued! the genus in 1878. Suter recognizes?

COOKE: ON RADULA OF ZLUTHRIA. 2338
7 species from New Zealand and the outlying islands, and there is at
least 1 Tasmanian species; Bartsch enumerates’ 9 more from the
Cape; 4 species, perhaps not all of them uthrva, have been
described ? from Japan, there is 1 from Kerguelin Island (chlorotica,
Marts.), and an outlying species, not always regarded as Huthria
(dira, Reeve), ranges from Puget Sound to the Californian islands.
The Magellanic region, including the Falklands, appears to be
the nucleus of a rich development of Authria. Strebel, under the_
eroups Pareuthria, Glypteuthria, and Anomacme, has enumerated *
17 species from this region, and Thiele* and KE. A. Smith ® have
added 1 and 2 respectively. Even so, the list of species described is
probably not exhausted.
Of the forty-three species mentioned above, the radula of cornea
was figured by Troschel® (Gebiss der Schnecken, ii, pl. vil, f. 11).
Hutton has figured the radula of fluvescens, linea, striata, and vittata,
and, doubtfully, of litlorinotdes.?. Troschel figures (pl. vil, f. 12) as
of lineata, Chem. (=J/inea, Mart.), a radula which is certainly that of
littorinoides. Thiele has figured * the radula of Pareuthria imnocens,
Smith.
In illustration of the present paper the radule of ten species
are figured, seven of them for the first time. All are from the
collection of the late Professor H. M. Gwatkin. The results suggest
that the forms hitherto grouped under Luthria are susceptible of
considerable subdivision, and that some must probably be removed
from that genus altogether.
The specimens examined fall into four distinct groups.
Group 1.—Rhachidian tooth tricuspid, cusps somewhat. blunt,
elevated, base sloping away rapidly, slope interrupted. on each side
by a blunt knob or tooth, base deeply arched below; laterals
tricuspid, simple, not much curved. To this type belong cornea, L.,
and linea, Mart.

solely on supposed conchological differences, mainly of structure. ‘‘ The
genus,’’ he remarks, ‘‘includes species of such different forms that
a revision and fresh grouping appears necessary.’? He admits that the
systematic value of the groups he names, Pareuthria, Glypteuthria, etc.,
is questionable, without any simultaneous knowledge of their anatomical
relations.

In cornea the base is much broader than in dinea, and less deeply
arched below, while the interruptions of the slope of the base, which
are mere knobs in cornea, are distinct denticles in Jinea. The lateral
cusps in /inea are blunt, and of nearly equal size, in cornea they are
sharper, the external cusp much the longest. In the rhachidian of
cornea there is no sign of the two subsidiary front denticles, making
five in all, as figured by Troschel. Sérvata, Hutt., if Hutton’s figure
is correct, is exactly the same type as linea.
Group 2.—Khachidian tooth with eight small denticles, nearly
equal in size, base broadly oblong, rounded above, arched below,
sides slightly prolonged into wings; laterals tricuspid, simple, curved -
inward, the two inner cusps close together, suggesting the sub-
division of a single cusp.
To this type belongs ferrea, Reeve.

The general form of radula has a close similarity to that of
Group (6) of the Cape Cominelle (delalandii, Kien., lagenaria, Lam.,
limbosa, Lam., porcata, Gmel.), as described antea, p. 229.
Group 3.—Rhachidian tooth tricuspid on a simple base, base usually
rounded at the top, scarcely arched below; laterals tricuspid, simple,
the two inner cusps close together, representing a single subdivided
cusp.
The New Zealand species (1) flavescens, Hutt., (2) lit¢orinoides,
Reeve, (3) vittata, Quoy, the Tasmanian (4) clarke’, T.-Woods, and
the Cape (5) quekett:, Smith, belong to thistype.
The radula of quekett’, however, with its square base, angled at
the top and arched below, is scarcely distinguishable from those
COOKE: ON GENERIC POSITION OF NORTHIA, 235
of the so-called Cape Cominelle, elongata, Dunk., and tigrina, Kien.
It has further the characteristic that the interior cusp of the
lateral is serrated all along the inner edge.
Group 4.—Rhachidian tooth tricuspid on a rather narrow base,
base strongly arched below, and more or less prolonged into wings;
laterals bicuspid, simple, outer cusp the longer and narrower.
To this type belong the Magellanic species antarctica, Smith, fuscata,
Brug., fuscata, Brug., var. curta, Prest., and innocens, Smith. There ~
is strong reason to suspect that Preston’s var. curta of fuscata, Brug.,!
is a distinct species from fuscata; the three rhachidian cusps are
differently shaped, and set at a different angle.” It appears from
von Martens’ description * of the radula of his 2. chlorotica that that
species also belongs to this group, and here too must be classified the
West American Z. dira, Reeve, which possesses a tricuspid rhachidian,
set on a base which is rounded above, and deeply arched below, sides
produced into wings; laterals bicuspid,‘ simple.
A comparison of the radule of Group 4 with those of the Cominelle
of New Zealand (antea, p. 228) will suggest the conclusion that the
Magellanic Euthrias are in fact Cominellas, and should be classified
as such. It is noticeable that, in the Falklands at least, ‘‘ Euthria”’
occurs on muddy shores, and Mr. Iredale tells me that in New
Zealand and on Norfolk Island Cominella is always found associated
with mud.

THE: GENERIC POSITION OF THE GENUS NORTHIA, GRAY.
By the Rev. A. H. Cooxe, Sc.D., F.Z.8.
Read 13th April, 1917.
Tuer genus Northia was constituted by Gray (Proc. Zool. Soc. Lond.,
1847, p. 140) for his Nassa northie. In his ‘ List of the Genera of
1 Ann. Mag. Nat. Hist., ser. viI, vol. xi, 1913, p. 218 (not figured).

placed Vorthia (misspelt Vorthea in the index) in the Vassina, next
after Desmoulea.
Nassa northie is figured in Griffith & Pidgeon’s edition of
Cuvier’s ‘‘Animal Kingdom”’, vol. xii, 1834, pl. xxx, f. 2.
Gray’s name does not appear, and the species therefore properly
belongs to the authors of the book. ‘here is no description in the
text. The specimen figured is manifestly immature, and is
probably the shell in Gray’s own collection in the Natural History
Museum, on the tablet of which is written, in Gray’s own hand,
‘¢ Northia?”
Kiener (Ieonog., livr. vi, Dee. 1834, p. 28, pl. ix, f. 28) figures
the species as Buceinum serratum of Dufresne, which is in all
probability a manuscript name.
Deshayes (in his edition of Lamarck’s Anim. sans Vert., vol. x,
1844, p. 192, No. 69) alters the name to Buceinum pristis, serrata
being preoccupied by Brocchi (Subapp. Foss., 1814, pl. v, f. 4) for
a fossil Vassa.
H. & A. Adams (Genera, vol. i, 1853, p. 111, pl. xii, f. 1) place
Northia in the subfam. Nassine between the genera Cominella and
Truncaria.
Chenu (Manuel, 1859, p. 159, f. 172) places Worthia as a sub-genus
of Buecinum, with Cominel/a and Amphissa.
VU
ae.
Tryon (Manual, vol. iv, 1882, p. 5) places Worthia first among the
genera of Nasside, immediately before Zruncaria, adding, however
(p. 8), that he thinks he would have placed it in the Terebride had
it not been already assigned to the Nasside, or to any other family.
P. Fischer (Jan. de Conch., 1884, p. 636) places Worthia in the
~ Nassidee, as a sub-genus of Dorsanum (= Pseudostrombus), which comes
between Canidia and Buceinanops (= Bullia).
Dall (Proc. U.S. Nat. Mus., vol. xxxvii, 1909, p. 215) places the
genus WVorthia in the family Alectrionide, as the Nasside must now
be called, between Alectrion and Buccinanops.
Thus the general consent of authorities places Vorthia in or near
the Alectrionide, a position which the shape of the shell, with its
handsomely toothed outer lip, might appear to warrant. But an
examination of the radula gives reason for modifying the current view.
As will be seen by an examination of the accompanying figure,
the laterals are bicuspid and simple, while the base of the rhachidian
tooth is narrow and arched, with the side produced below into
wings. Both these points are characteristic of Alectrion, and of
other genera as well, but here the resemblance ceases, while the
COOKE: ON GENERIC POSITION OF NORTHIA. Ia
significant feature of an Alectrion radula, the numerous small
denticles of the rhachidian, smaller at the sides than in the middle,
is absent altogether.
In its place we find on the rhachidian tooth three large strong
denticles, the central denticle rather the largest, base narrow, sides
squarish, strongly winged. The laterals are bicuspid, simple, exterior
cusp longer and thinner than the interior cusp, which is strong and
remarkably broad. ;
This combination of a bicuspid lateral, having the inner cusp
the broader and stouter, with a tricuspid rhachidian, having cusps
nearly equal in size, set on a narrow base with sides prolonged
into wings, is characteristic of a section of the genus Phos, to which
Northia stands undoubtedly in very close relationship. Compare
the figures of the radule of Phos senticosum, Lam.,-and Phos
cancellatum, Quoy, given in Troschel, Das Gebiss der Schnecken,
vol. ii, pl. vili, f. 1, 2. A very sharp subdivision of the species
hitherto united under Phos is indicated by an examination of the
rhachidian tooth, for, besides senticosum, Lam., and cancellatum, Quoy,
roscatum, Hinds, and varvans, Sowb., possess the tricuspid rhachidian
(and so also does tasmanicum,' Ten.- Woods), while gaudens, Hinds,
nodicostatum, A. Ad., and pallidum, Hinds, have a rhachidian with
more numerous denticles, of an Alectrion type.
So far as the radula is concerned, Northia and Phos stand in
somewhat close relationship to the Cominelle of New Zealand and
Australia, and, to a less degree, to certain Australo-Neozealanian
species of Huthria. All these four genera are much more closely
related to Buccinum than they are to Alectrion, and should be
grouped accordingly.
The shape of the operculum of Northia confirms the view that the
genus is related to the Photide and not to the Alectrionide. As
given in the figure of H. & A. Adams’ ‘‘Genera”, pl. xii, la, 16,
it is rather thick, long, and narrow, narrowing towards the nucleus,
which is terminal and slightly hooked. That of Phos is similar,
though not quite so thick, with a sub-terminal nucleus. Adams’
figure of Worthia is not quite correct ; specimens do not show a marked
notch close to the terminal nucleus.
It should be noted that the two other species (albopunctata,
Ad. & Reeve, and rissoides, Reeve) classified as Northia by the
Adams and by Tryon, have no claim to that position. Still less is
Pleurotoma (Daphnella) boholensis, Reeve, a Northia, as suggested by
Couturier (Journ. de Conch., tom. iv, 1907, p. 130).

Among the shells in the Layard Collection (acquired by Sowerby

found bearing on the back of its tablet ‘‘type”’; this find is important
since in Pilsbry’s monograph of Partula, ‘‘ Manual of Conchology,”
ser. 11, vol. xx, 1909, p. 306, it is stated that ‘‘ Dr. Hartmann has
recorded the loss of the type of this species by shipwreck on its return
voyage to Mr. Garrett at Tahiti’’; a quotation is also given from
a letter of Dr. Hartmann’s, ‘‘I received this shell from Mr, Layard
through Mr. A. Garrett.”
The specimen agrees perfectly with the description and dimensions
given by Dr. Hartmann, and it is probable that the shell was
returned direct to Mr. Layard and not through Mr. Garrett, and
therefore did not get lost as was supposed.

a conchologist of Newcastle, to make the comparison, and he most
kindly did so, and reports that the specimen sent him agrees in
all material respects with the type, which, as in my specimen also,
has no spiral strie. I intend placing in our national collection the

PRESIDENTIAL ADDRESS.
By J. R. Le Brocxron Tomtry, M.A., F.E.S., ete.
Delivered 9th February, 1917.
A SYSTEMATIC LIST OF THE MARGINELLIDA.
In the List which follows I have endeavoured to put together all
the specific and varietal names which have been applied by authors
to actual or supposed members of the family of the Marginellide.
My only regret is that, so far, time has not allowed me to include
the fossil forms. From the point of view of synonymy this is
a serious omission, which I trust to be able to repair later on.
Meanwhile, where the name of a recent species is preoccupied by
a fossil one, I believe that I have always noted the fact. In forming
such a list I have had an excellent model to follow in that of the
Columbellide, by 8S. Pace, in vol. v of these Proceedings.
I have found, just as he did, that there are many names which
have never been included in monographs of the group with which
I am dealing, many type-specimens which cannot be traced, even
several which are stated to be in our national collection. I have
come across the usual crop of those tiresome and useless weeds—
nomina nuda. It is very curious to note how gradually and insidiously
these pests creep into literature, and how in many cases a false
reference is copied from one writer to another until it acquires quite
a traditional and respectable position. The length of time during
which one of these upstarts will maintain its false status is
extraordinary, and is incidentally a useful piece of evidence to show
how little pains successive copyists take to verify the references
which they employ. If I have in a few cases below cited a name
‘ex So-and-so MS., it is only in deference to the custom which
obtains at present. A point with regard to specific names which is
much overlooked, especially by certain living authors who have
a passion for varietal names, is that under the present code these
names are on precisely the same footing as the specific names in their
genus. Consequently, and I may say fortunately, the inevitable
multiplication of ‘var. major”’, ‘Svar. minor’, ‘var. alba”’, and the
like has the very opposite effect to that intended by their sponsors,
and 99 per cent of them come into literature stillborn.
I take the family Marginellide as defined in Dr. Paul Fischer’s
Manuel de Conchyliologie, with the exception of the genus Mficrovoluta,
placed by him doubtfully in this family, but now believed to belong
to the Volutide or possibly to the Mitride. I unhesitatingly reject
from the family von Martens’ sub-genus Marginellona, formed in 1903
for the reception of a species dredged by the German Deep-sea
Expedition. Only a single, much broken live specimen was procured,
but there is enough to show that the structure of the columella
is totally different from any known form of Marginellid. Von Martens
admits that the shell characters are Volutoid, but considers that the
TOMLIN : A SYSTEMATIC LIST OF THE MARGINELLIDZ. 243
radula is nearer to that of Marginella. I retain the two species
of Pachybathron, owing to the continued uncertainty as to their
affinities. It will be found that I have throughout erred rather
on the side of inclusion than of exclusion, and I am convinced that
this is the correct attitude in drawing up a list of this kind. Thus it
has seemed convenient to include all the species placed by Bolten in
the genus Pferygia, and all that I find at any time to have been
attributed to Volvaria. Much confusion arose over this genus owing
to Lamarck, who, after erecting it in 1801 for the Tertiary fossil
V. bulloides, introduced into it in 1822 several species of Marginellids.
The fossil has punctured strize as in Actg@on and the form of a Bullinella,
and there can be little doubt that Roissy and D’Orbigny were right
in placing it among the Tectibranchs. It might possibly have been
more consistent similarly to list everything that has been credited to
Voluta, but this would have added very largely to my task, and
hardly seemed necessary in view of the very small number of
Marginellide known at the period when Voluta had so comprehensive
a use.
The author of the list of Columbellide already referred to did not
profess, except in a few cases, to deal with the identification or
synonymy of the names he catalogued, though he seems to have
contemplated undertaking such a task in a succeeding paper. ‘This
is a question with which [ have endeavoured to deal, nor have I been
content to accept blindly the dicta of previous writers, but have
in most cases formed an unbiassed opinion by the comparison of
authentic specimens.
The order followed in cataloguing each item is as follows: after
the specific name and that of the author comes the genus (in brackets)
to which the name was attributed in the original description; then
the date of publication as exactly as possible, and the reference to
the original description, such references being invariably quoted
from the actual work or serial and not from reprints or separata with
altered and misleading pagination. The type locality follows and
the location of type or types when I have been able to ascertain it.
It should be inferred that omission of locality implies a similar
omission on the part of the describer, except in cases where a specific
name has been proposed to replace another on the score of pre-
occupation. It is then obvious that the type locality and type-
specimen relating to the preoccupied name pertain alike to its
successor, but to economize space they have not been mentioned
again. Names are all copied exactly as spelt by their authors, and
as far as I remember there are only three cases of obvious typo-
graphical error where emendation has been permissible, viz. /evigata,
Braz., aureocincta, Stearns, and sentilla, Jouss. Where ‘‘(var.)’’ is
appended to a name, it signifies that that name was a varietal one
in the first instance. Misspellings are troublesome and numerous
though comparatively unimportant; it will, however, be found that
most of them are noticed below, though such are not cited when
incidentally occurring in the text of a work. Petit de la Saussaye,
Paetel, and Weinkauff are far the worst offenders in this way, the
244 PROCKEDINGS OF THE MALACOLOGICAL SOCIETY.
last writer’s ‘‘excellent synonymic catalogue’’—to use Tryon’s
encomium—showing seventeen cases of such erroneous names.
I cannot trace the family name Marginellide further back than
1858, when it was used by H. & A. Adams with much the same ™
limits as Fischer gave it, except that they included rato, which
is now said to have the animal and radula of a Zrivia and has
gone to the neighbourhood of the Cypreide. Redfield claimed to
have used it in 1851, but this was only in a privately printed
catalogue of his collection. An excellent historical survey is given
by Jousseaume of the earlier classification of the group. ‘The

Though one may select small groups with certain well-marked
characteristics, yet they easily grade into one another when the
multitude of species is examined seriatim, and so far the number
whose soft parts and radule are known is very small. Professor
Gwatkin told me last year that he only had the radule of seventeen
species, and that it was an extremely hard one to extract. He
added, ‘‘the radula is as anomalous as Gadinia. I can think of
nothing like it. The nearest is Olivella and some of Troschel’s
figures of Zurricula and Ancilla. The side teeth are obsolete—an
interesting converse of Columbella, etc., where the centrals are
degraded.”
Bolten placed all his species of Marginella, with some Volutes and
others, in a genus Plerygia. Dall has recently designated P. nucella,
Bolten, = Voluta dactylus, L., as the type of this genus (Bull. U.S.
Nat. Mus., No. 90, p. 51), whereby it becomes equivalent and of
course anterior to Cylindromitra, Fischer. Pseudomarginella was
founded on specimens collected at Goree, whose animals were
furnished with an unguiculate operculum, while two were said to
have a Buccinoid and one a Purpuroid radula. ‘he shells of these
forms, as admitted by the authors and as figured, were absolutely
indistinguishable from typical JL glabella, L. The existence of
operculate and non-operculate specimens in the same species is not
impossible, though I believe this is the only case of operculate
Marginellids on record, but the statements made by von Maltzan and
Carriére as to the radule have always been received with incredulity,
and it is much to be regretted that in the period of thirty-six years
that has now elapsed no further evidence has been forthcoming.
The most noticeable characteristic of a Marginellid shell is the
strong plaits on the lower part of the columella. The usual number
of plaits is four, but some species have only two, whilst in other
cases they run to nine or ten, as in cornea, Lam., and a nearly
related species, robusta, Sow., figured in the fourth volume of our
Proceedings, has even more. On breaking open the shells of various
species, it will be found that these plaits revolve round the columella
the whole way up, not decreasing at all in strength, but only to the
246 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
number of four as a rule. Where there are more than four in
the aperture, the extra ones appear as hardly more than tubercles or
continue within only for a very short distance. ‘The only species
that [ have examined which have more than four throughout are
ventricosa, Fischer, and its very near relative loebbeckeana, Wkff.
These have five. Young specimens are sometimes found to have
a larger number of plaits than adults of the same species. The plaits
vary in the angle of their setting on the columella, and it is obvious
that in the Persicula group, which has no spire, they will be practically
at right angles to the axis.
One very curious fact about this family which has often been
commented on is the comparatively large number of cases of
sinistrorsity which it supplies. This teratological feature is so
excessively rare amongst recent marine Gastropods that I know of
only thirty-seven or thirty-eight species in which it is on record,
and of these nineteen or 50 per cent are Marginellids. Among
fossil Mollusca three species out of the nine so recorded belong to
this family.
The Marginellide are almost exclusively natives of warm or
tropical seas, living as a rule on sand in a few fathoms of water.
Occasionally they occur between tidemarks, and I have found the
Mediterranean Jf. clandestina, Broc., living at low water amongst
small seaweeds on the coast of Sicily. Certain species have been
dredged at considerable depths by the Challenger, Blake, Travailleur &
Talisman, ete. With very few exceptions the known species
occur between the 40th North and South parallels of latitude, and
though they are of general occurrence in these warmer waters, yet
certain regions are noteworthy as producing an unusual number
of species, namely, the West African coast, the Caribbean region,
Australia, and the Cape district. Curiously enough, the first three of
these, as at present known, have each about seventy-four or seventy-
five species. Probably Australia will add to this total in the future
much more largely than either of the others. On the West African
coast the Marginellids form quite an appreciable fraction of the
molluscan fauna; the Gruvel Expedition in 1909-10 dredged thirty-
four out of a total of 519 species, or 63 per cent. The northern and
southern limits of the west coast fauna are rather sharply defined,
the former being somewhere about the Tropic of Cancer, the latter in
the neighbourhood of Mossamedes. A small parcel recently received
from Walfisch Bay consists entirely of a species either identical with,
or at most a variety of JZ. capensis, Krauss. ‘The 300 miles of coast
from Mossamedes to Capetown seems singularly little known, but its
fauna will, I think, prove to belong to the Cape. Three species
of Marginella are known from St. Helena, one from Ascension, and
forty-three from the Cape. Four or five only occur on the East
African coast, while the Mascarenes have fourteen. Fifty-six species
are scattered from the Red*Sea eastwards to the China Sea, and
seventeen are recorded from various stations in the Pacific. As
already stated, Australian waters at present account for seventy-five,
and New Zealand has ten endemic species. On the Pacific coast of
TOMLIN: A SYSTEMATIC LIST OF THE MARGINELLIDA. 247
America thirteen or fourteen are known from California to Peru,
half a dozen come from the Magellan—Falklands area, and perhaps
a dozen species are known along the east coast south of the Amazon.
The richness of the Caribbean region has already been mentioned,
and a very small number thence struggle north as far as Cape
Hatteras.
The Mediterranean has some nine or ten. I should perhaps
mention that Thiele reports a single immature specimen (Jf. hyalina,

F. B. Loomis, of Amherst, Mass., W. F. Clapp, of Cambridge, Mass.,
G. B. Sowerby, F. H. Gatliff, and most of all to T. Iredale, who
has always placed his admirably accurate knowledge and advice
ungrudgingly at my disposal.

of “ W. Indies” is given; Sowerby’s original locality is wrong.

down. I cannot find any shell in the British Museum which
could be the original of Reeve’s figure.

According to Martens the radula resembles that of Marginella,
though the shell characters are more like that of Voluta.
Judging from the figures I have no hesitation in rejecting this

catcuLus, Redf., and 209, 210 macutosa, Kien. (cf. Redf. in
Amer. Journ. Conch., vi, 173, who, however, did not notice that
Sowerby had figured two species). Zypes.—In the Brit. Mus. are
three examples labelled above “ swainsoniana, Pet., St. Vincent’s”’,
and below “‘guttata, Swains. = swainsoniana, Pet. = maculosa,
Kien., fide Reeve & Sowerby, M.C.” This nomenclature is
incorrect and confuses guttata, Sw., with guttata, Sow.; guttata,
Sw. = swainsoniana, Pet. = phrygia, Sow. The three shells are
probably the originals of Sowerby’s f. 209, 210. There are also
three labelled above, “ swainsoniana var., St. Vincent’s,” and below
“ guttata, Sw., M.C.” This again is incorrect and shows the same
confusion. ‘l'hese three are calculus, Redf., and one of them is
probably the original of Sowerby’s f. 208.

a var. of prrerara, Hds., or distinct, requires further con-

“Shell minute, ovately cylindrical, brownish, smooth, shining, trans-
lucent : whorls 3, rounded : aperture narrow, slightly increasing in width
towards anterior margin, where there is a single fold forming its reflexed
margin : outer lip simple: spire scarcely elevated. Long. 2 mm., lat.
15mm.
“ Habitat, Brown’s River, dredged in about 6 fathoms.”
It is quoted in Tate & May’s “ Revised Census of the Marine Mollusca
of Tasmania”, Proc. Linn. Soc. New South Wales, xxvi, 1901, p. 363, as
above, without further information, and in a letter dated December 5, 1916,
Dr. May says :—‘‘ Mf. lubrica, Pett., type lost, and no other specimen
known. It may yet be found, but it is to me a rather doubtful species.”
The missing type has now been found, among Messrs. Sowerby & Fulton’s
stock of Marginellide, in a box purchased at the C. E. Beddome sale, and
labelled underneath in that collector’s writing, ‘‘ Volvaria lubrica, Pett.,
Tasmania.” I believe that Beddome when living at Hobart used to
purchase specimens from Petterd. The specimen tallies well with the
description, is a live shell and has the animal still inside—hence the
“brownish” colour, but on cleaning the aperture carefully I found it to be
triplicate, the uppermost fold being very faint. Hedley records a similar
inaccuracy in the figure of the type-specimen of M. angusz, Crs. (Proc.
Linn. Soc. New South Wales, xxxix, 1914, p. 726). Petterd’s shell is
closely related to M. angasi, but the material at my disposal does not
lead me to unite them. Mr. Fulton has asked me to place this unique
type in the British Museum. J. R. Le B. Tomuin.

NOTES ON DONOVAN’S NATURALIST’S REPOSITORY.
By A. Reyne t.
Read 11th May, 1917.
Tue work under consideration is usually represented as consisting of
five volumes, each volume dated 1834 on title-page. As far as the
first two volumes are concerned, these were first issued in parts,
vol.i in 1822-3 and vol. ii in 1823-4, and the book so far considered
complete that Simpkin Marshall printed title-pages, undated, on
which it was stated that the work was in two volumes.
Donovan’s advertisement, dated from Lambeth, March Ist, 1828,
remarks, ‘‘The ‘'welth Number of this work is now respectfully
submitted to the attention of the public. This number, accompanied
by the Title Page and Index, renders the first volume complete. The
Subscribers, therefore, are now enabled to form a correct idea of the
nature and object of the undertaking: and from the style in which
it has been so far conducted, to form some conclusion of that in which
it is likely for the future to be continued.” This advertisement also
appears in vol. i of the 1834 edition.
Each plate is dated, both the day of the month and the year being
given. Part i, arguing from the advertisement in vol. i, and the
date on plate ii,! was issued on April Ist, 1822, and the dating on the
plates as far as vols. i and ii are concerned is the actual date of issue.
The plates of vols. iii to v are all dated between April Ist, 1824, and
December Ist, 1826, the first-mentioned date appearing on the first
plate of vol. iii, and the latter on the last plate of vol. v, but we
have no evidence at present that vols. ili-v were issued before 1834
beyond the statement that the plates were published on the dates
specified ‘‘as the Act directs by C. Donovan and Messrs. Simpkin &
Marshall ’’.

ON AN ABNORMAL SPECIMEN OF COCHLICOPA LUBRICA.
By E. W. Bowett, M.A., M.R.C.S8., ete.
Read 11th May, 1917.
Wuitr searching in an old hedgebank at Radlett, in the parish of
Aldenham, Hertfordshire, on April 22nd, 1917, I came across the
remarkable snail which is here described. It was crawling about in
a tuft of moss, was quite lively, and showed no difficulty in managing
the large shell. Other species present in the immediate vicinity
were Limax agrestis, Arion ater, A. circumscriptus, A. hortensis,
Pyramidula rotundata, Theba cautiana, Polita nitidula, P. cellaria,
P.alliaria, P. rogersi, P. pura, Clausilia rugosa, and Cochlicopa
lubrica.
This shell differs from a normal Cochlicopa lubrica in being 11°1 mm.
long and 34mm. in diameter; it has about seven whorls or rather
more. ‘The peristome is not thickened or coloured, indicating either
growth was not complete, or that for some reason the specimen was
constitutionally unable to produce the usual termination for its shell
building. At the fourth whorl from the apex the shell shows what
looks like a mended crack; if the animal had proceeded to form
a peristome soon after reaching this point of development it might
have produced a shell of nearly normal size and shape, and the scar
may indicate some hesitation in the matter. Comparison of super-
imposed photographs shows without very much doubt that the apical
whorls of the present specimen are as near identical in size and form
with those of a normal lubrica as can be.
Scale line = 4mm.
The radula is longer and wider than in lubrica, though this
enlargement is not in proportion to the magnitude of the shell. The
central uncus is longer and there are more admedians, more externals,
and more rows. ‘The total number of unci is therefore increased,
roughly in proportion to the increased length of the shell.

BOWELL: ON AN ABNORMAL SPECIMEN OF COCHLICOPA LUBRICA. 318
The body of the snail when extracted from the shell was not found
to be disproportionately small, as I have previously found in extra
large specimens of Limnea. The anatomy was examined by serial
sections ; no gross abnormality was found, and the genitalia have the
morphology normal to dubrica.' The genitalia are, however, small
(smaller than in normal Jubrica) and undeveloped, and the herma-
phrodite gland is represented by a mass of reticular connective
tissue without any trace of eggs, or spermatozoa, or of cells which
might be presumed to be their precursors.
Assuming that the present specimen is in fact C. lubrica, it is
evident it is monstrously large, the bulk being four or five times
that of the normal shell. In the absence of definite signs of the
termination of growth, it is difficult to be quite precise about the
normal size and variability of /wbrica, but there is a general consensus
among the authorities who happen to be available that the normal
length is about 6mm.
To get some measure of the local size variation, the 67 largest
specimens which seemed to be adult out of about 150 collected from
the rejectamenta of the River Colne were examined; the mean was
5°7 X 2°4,7 maximum 6°5 x 2°6 and 6:4 X 2°8, minimum 5:0 X 2°83,
coefficient of variation 6°38. Taking the mean length as 6 mm., if the
coefficient of variation were as much as 10, the greatest normal
range would be about 4 to 8 mm., if it were 5 (a more likely figure)
about 4°5 to 75mm. In any case it is evident that the present
specimen is definitely beyond the range of normal variation.
What appear to be similar monstrous forms have been noticed
before. J. W. Taylor describes * under the name Azeca elongata two
specimens of 4. tridens (?) 9 X 2°5 mm. (as against a normal measure-
-ment of about 6°25 x 2°5) with 94 instead of 7 whorls, one from North
Walesand one from Yorkshire; J. W. Jackson has a holocene lubrica(?)
10 mm. long from the talus of a cave at Clapham in Yorkshire.‘ It
is perhaps significant that in each case only a single specimen was
found and that all these concern allied forms. I know of no obviously
parallel case among other land mollusca, though Mr- Tomlin suggests
that the shell he described * as Vertigo heldi was a similarly monstrous
V. pygmea.
For the present I prefer to regard my specimen as a form of
Cochlicopa lubrica until more is known as to its nature. It may
well be that these sporadic giants represent an attempt or a tendency
1 See Sternberg’s figure in his Fauna of Denmark: Land Mollusca.
Thering’s figure reproduced by Taylor (Monograph, vol. i, 1900, p. 356)
is incorrect. Moquin-Tandon’s figure (Histoire, ii, 1855, pl. xxii, fig. 17)
is right, except that he omits the diverticulum on the duct of the
spermatheca.
2 Mean sizes determined from specimens as collected are generally somewhat
less than those in the textbooks, which are presumably taken from
picked specimens.

on the part of ¢rédens and lubrica to divide into two species with the
same sort of relationship as Ena montana and £. obscura,’ and the
varietal name og,” which I would propose for this form, must not be
taken as implying that it is residual rather than nascent. On the
other hand the absence of definite gigantism in the earlier stages of
growth, the apparent break between the normal and abnormal parts
and the absence of ova and spermatozoa suggest that it may belong
to one of the types of abnormal somatic growth which are known
to be associated with irregular developments and sexual cells.
The specimen has been deposited in the collection of the
Conchological Society in the Manchester Museum.
1 The similarities and differences in the radule of these two species are just
the same as in og and lwbrica.

OTINA OTIS (TURTON) ON THE COUNTY DOWN COAST.
By A. W. Sretrox.
Read 8th June, 1917.
Last year, at the request of Mr. H. Wallis Kew, I was working the
coast in the vicinity of Ballymacormick Point, for the False
Scorpion, Odisium maritimum. During this successful search I became
acquainted with a most interesting association of marine and semi-
marine animals, the existence of which I was previously unaware.
This includes, besides the Obiscwm, two beetles of the genera
Aépus and Micralymma; the Collembolan Anurida maritima; various
species of mites; Zasea rubra and other marine mollusks; as well as
marine annelids, and finally an abundance of Ovatella bidentata, which
on one occasion was accompanied by Otina otis.
The situation of Ballymacormick Point, which lies about a mile
east of Bangor, and just outside and south of Belfast Lough, renders
this habitat free from any trace of brackish water. Moreover, heavy
seas break over the low rocks during rough weather. I was a little
surprised, therefore, to find Ovatella bidentata in such abundance and
in such a purely marine habitat, having associated it in my mind
with more estuarine conditions. The exact habitat for this association
of animals is at about 6 to 8 feet below mean high water mark, or
just at the base of the zone of the alga Fucus vesciculosus, and in the
uppermost part of the zone of the cirriped Balanus balanoides. All
live between the layers of the Ordovician slates, which in this locality
are tilted almost vertically; jagged edges, with deep crevices
between, being everywhere to be seen on the upper surface of the
rock. Into these crannies during and after storms are washed broken
mollusca, crabs, and many other animals, which have been dashed to
pieces on the rocks by the force of the waves. At high tide the
air-breathing members of the association are forced to remain in the
worm burrows and cavities, which everywhere traverse the fine
muddy matrix which has filtered into the cracks between the slaty
layers. In these subterranean passages a considerable quantity of
air is perforce imprisoned during high tide, thus preventing the sea-
water penetrating the burrows and drowning the air-breathers. At
low water they are free to come out into the open air and feed on
the animal and vegetable material washed into the crevices by the
last tide.
It was upon my third visit to the locality that I made the
acquaintance of Otina otis, a species I had often looked for previously,
but in vain. These occurred in a small colony, about a dozen
specimens, in one of the crevices; and looked at first like little lumps
of brown jelly. A penny coin would have covered the whole group,
most of which were very small.
Very few definite records exist for this little-known mollusk,
which is probably common and widely distributed along the more
rocky parts of our coast, and so far as I am aware it has not been

reported previously from the east coast of Ireland, though long
known to live on the island of Arran in Scotland, which lies within
sight of Ballymacormick Point on the northern horizon.
The possible absence of this species from the eastern coast of
Ireland, might be accounted for by the fact that from Down south-
ward to Wexford there are few localities where a rocky coast occurs,
Lambay, Ireland’s Eye, Howth, and Bray Head being the chief
possible habitats. Along the remaining parts of the east coast, for
the most part, blown sand alternates with low cliffs of glacial drift.

MORE MOLLUSCAN NAME-CHANGES, GENERIC AND SPECIFIC.
By Tom Ireparr.
Read 13th April, 1917.
SuMMARY.
Volema, Bolten, type V. paradisiaca, Bolten, has priority over Melongena,
Schumacher, but may be used independently.
Mayena, gen. noy., proposed for Biplex australasia, Perry.
Turricula, Schumacher, is the correct name for Surcula, H. & A. Adams.
Gelagna, Schaufuss, is equal to and antedates Paralagena, Dall.
Partulida, Schaufuss, should replace Spiralinella, Chaster.
Campanile, Fischer, has for type the recent species Cerithiwm leve, Quoy &
Gaimard, which is here renamed Campanile symbolicum, sp. nov.
Campanilopa, gen. novy., introduced for the fossil Cerithiwm giganteum,
Lam.
Pleurotomoides, Bronn, has priority over Lora, Gistel, and Clathurella,
Carpenter, all proposed as alternatives for Defrancia, Millet, preoccupied.
Gabrielona, gen. nov., proposed for Phasianella nepeanensis, Gatliff & Gabriel.
Orbitestella, gen. nov., for Cyclostrema bastowi, Gatliff.
Megathura, Pilsbry, should be used instead of Macrochasma, Dall.
Mitromorpha, auctt., is not Mitromorpha, Carpenter, which was based on
Daphnella (?) filosa, Carpenter.
Antimitra, gen. nov., is proposed for Plewrotoma egrota, Reeve, with which
A. Adams’ Mitromorpha lirata is congeneric.
Lovellona, gen. nov., type Conus atramentosus, Reeve.
Apaturris, gen. nov., type Mitramorpha expeditionis, Oliver.
Callanaitis, gen. nov., type Venus yatei, Gray, for Salacia, Jukes-Browne,
preoccupied.
Anopsia, Gistel, is available for Psyche, Rang, preoccupied, and has priority
over Verrillopsyche, Cossmann, proposed for Halopsyche, Kieferstein,
preoccupied, introduced as substitute for Rang’s name.
Hydromyles, Gistel, should be used for Huribia, Rang, preoccupied, as it is
older than Kieferstein’s name Theceurybia, for the same genus.
Once again I offer solutions of some nomenclatural problems for
the purpose of criticism, the majority of those which do not invite
consideration being withheld. I acknowledge once more such criticism
from Dr. Dall and M. Cossmann, but I must complain of each of these
writers demurring against my non-acceptance of vernacular names.
Each indicates that my rejection of French vernacular names,
i.e. ‘‘ Les Phacoides”’ and ‘‘ Les Subémarginules’’, is an instance of
hypercriticism, and that I am wasting time on matters not worth
questioning. I have often gone over the International Rules, and
have been unable to find any item whereby French vernacular generic
names are legalized, and so must continue to reject such whenever
they have been wrongly used, notwithstanding the adverse criticism
of my two famous friends.
I would recall that Dall himself wrote (Trans. Wagner Free Inst.
Science, Philad., vol. iii, pt. 1i, Dec. 1892, p. 306), ‘‘ Deshayes cites
‘Tenagode’ simply, and such a trivial name in the vernacular has no
just claim to recognition.” I therefore quote that Blainville wrote
‘‘Les C. Chenilles, Les B. Nassoides, Les R. Buccinoides, Les
JREDALE: MOLLUSCAN NAME-CHANGES. 323
P. buccinoides’’, etc. The ‘‘C.”? might mean ‘‘ Cerite”’ or ‘ Ceri-
thium ”’, the ‘‘ B.”’ ‘* Bucein”’, or ‘‘ Buccinum ”’, but the ‘‘ R.” stood
for ‘‘ Rocher”’ not ‘‘ Murex ”’, hence all these names are absolutely
French vernaculars. I have only instanced the above, but I have
gone over all Blainville’s essay, and my contention is unassailable.
Cossmann’s further claim that a// French vernaculars should be
accepted as equivalent to Latin generic names is contrary to facts
and usage, as such have been almost consistently ignored, the few
instances that have now cropped up being due to the carelessness of
recent authors.
Vorema, Bolten.
When Dall discussed the Boltenian names (Journ. Conch., vol. xi,
1906, p. 289 et seq.) he indicated this name as needing special study,
thus :—
‘* Volema (1. pyrum, Gmel.). Turbinella pars, Lam., 1799, etc.”
Then later
«« Xancus (t. Voluta pyrum, Gmel.). TZurbinella, Lam., 1799. See
above, Volema.’’ :
Since the name Xancus was absolutely equivalent to Zurbinella it
has been used to displace it, and it does not seem wise to disturb
that usage. However, since Volema has priority it needs settlement.
In the same place Dall indicated that Galeodes, Bolten, was equivalent
to and should displace MMelongena, but Bolten’s choice had been
anticipated, so that Melongena has been resumed.
Volema, however, has priority over MJelongena, and the species are
often considered as congeneric, so that I think it best to definitely
fix Volema with a type species. Upon investigation I found that
Gray in 1847 did not know Bolten’s name, but Morch in 1852
included it as a sub-genus of Cassidulus, Humphrey, citing as
equivalent Pugilina, Schumacher, and naming under it the species
pugilinus, Born, and paradisiacus, Mart. = nodosa, Lam. ‘The latter
species has been commonly associated with Bolten’s name, and since
Bolten included Martini’s species under a binomial name Volema
paradisiaca I here designate that species as type. ‘This will leave
Melongena to the other species, which I do not consider congeneric.
I might state that it is possible that distinct sub-species of V. para-
disiaca, Bolten, will later be recognized, as the nodose forms seem
constant according to locality, and so are the smooth ones. At any
rate I have thirty-two specimens collected by Mr. Robin Kemp, near
Mombasa, British East Africa, which in every growth stage show
perfect constancy, not one of them developing nodulous seulpture
after the first three whorls. These are obsoletely nodulose, showing
that the smooth shell has developed from a nodule-bearing ancestor.
This note serves only to draw attention to the genus name, for
I observe that Volema pyrum, Bolten, has been indicated by Dall
as being equivalent to Pyrula nodosa, Lamarck, and it has precedence
in Bolten’s arrangement. Consequently if it be proved that these
are conspecific, the names would be Volema pyrum, Bolten = Pyrula
.

nodosa, Lamarck, and var. paradisiaca, Bolten = cttrina, Lamarck
(fide Dall) = paradisiaca, Reeve. I will deal with this later.
MaYyeEna, gen. nov.
I propose this name for Biplea australasia, Perry. In these
Proceedings (vol. xi, 1915, p. 284) the late Mr. E. A. Smith, after
relating the peregrinations of this species from one genus to another,
citing Biplex, Ranella, Triton, Bursa, Gyrineum, Apollon, Lotorium,
Argobuccinum, and Septa, and rejecting all these, placed itin Charonia.
Privately he admitted this was only a tentative location, but
conservatively declined to propose for it a new generic name, though
not adverse to such a suggestion. Simultaneously Bartsch, dealing
with South African shells, classed the South African representative
in still another genus, viz. Hugyrina. The species have a peculiar
facies, and, as can be guessed from the above resumé, do not correlate
well with any named group. Since Smith’s account we have benefited
by the publication in these Proceedings (vol. xii, 1916, pp. 5 et seqq.)
of a valuable paper entitled ‘‘On the Operculum of Bursa”, by the
Rev. Dr. Cooke. After discussing this point, Dr. Cooke added,
‘‘The evidence of the radula . . .”’ and from this it is easily seen
that the radula of the present group is as discordant as the shell
characters. ‘‘ Unlike both Bursa and ‘ Triton’ proper” are Cooke’s
words, and figures are given to prove this statement. Had this
evidence been available to Smith his doubt would have been
dissipated and he would have certainly proposed a generic term for
the species. I state this because I often discussed the matter with
him, and now remedy the matter by introducing the above name, in
honour of Mr. W. L. May, the Tasmanian conchologist, to whom all
students are indebted for many valuable items. Only two species
are known, australasia, Perry, and gemmifera, Euthyme.
Turricura, Schumacher, vice Surcuta, H. & A. Adams.
In the consideration of molluscan generic names some extraordinary
cases bewilder the student. ‘he present is one of these. Zurricula
was proposed by Schumacher in the Essai Nouv. Syst. Test.,
1817, pp. 66, 217, for the species Zurricula flammea alone, based on
Chemn., iv, p. 172, tab. 1438, figs. 1386-8. In the Gen. Ree. Moll.,
vol. i, 1853, p. 88, H. & A. Adams introduced Sureula for ‘‘ Turrt-
cula, Schum. non Klein’’. Adams’ name has continued in usage
ever since, though it was early recognized that Klein’s names had
no effect upon present-day nomenclatorial use. I noted that there
was a Turricula, Hermann, which was not nomenclatorially valid,
and therefore the first user after Hermann’s time had a perfect claim.
This proves to be Schumacher, and at the present time I know of no
reason why his name should not be resumed vice Surcuda.
Grraena, Schaufuss, vice Paratacena, Dall.
In 1869 a Catalogue of the Paetel Collection was published, and
a systematic synopsis given, the whole prepared by Schaufuss.
A few of the names were altered by Schaufuss, and most have been
IREDALE: MOLLUSCAN NAME-CHANGES ~ 325
noted and some are in use. I note a couple of omissions which
necessitate changes. Thus on p. 3 Schaufuss proposed Gelagna for
Lagena, Klein, as a sub-genus of Zritoncum, Lm. On pp. 28 and 29
the species referred to this group are chemnitzii, Gray, cingulatum,
Lm., and clandestinum, Ch. ‘The last-named has been regarded as the
Kleinian species, so I designate it as type of Gelagna. Unfortunately
this discovery will necessitate the rejection of Paralagena, Dall,
proposed (Smithson Miscell. Coll., vol. xlvii, 1904) for the same
group. Although clandestinum, Dillwyn, 1817, ex Chemnitz, has
been used for the species name, I note that Hedley preferred
succinctum, Linn., and followed Dall in placing the species in Argo-
buccinum. I might point out that clandestinum had been used by
Lamarck in 1816, and that there is apparently also a Boltenian name
available. I will treat these items later.
Parrutipa, Schaufuss, vice SprraLtneLta, Chaster.
On p. 6 of the Paetel Catalogue, Schaufuss proposed the above name
for ‘‘ Parthenia, Adams, not Lowe”’, the latter being also utilized.
In the Gen. Rec. Moll., vol. i, 1853, p. 233, H. & A. Adams used
Parthenia (as of Lowe), giving as members decussata, Mont., excavata,
Phil., enterstincta, Mont., and spiralis, Mont. These writers always
gave their species in alphabetical order, so that the first species might
not even be typical. We know, however, that they made use, to
a great extent, of J. E. Gray’s systematic work, and in the Proc.
Zool. Soc. Lond., 1847, p. 159, Gray gave as type of ‘‘ Parthenia,
Lowe, Turbo spiralis, Mont.’”? This was not one of Lowe’s species, as
Schaufuss recognized, so that I here designate as type of Lartulida,
Schaufuss, the species Zurbo spiralis, Mont. This course will
necessitate the acceptance of Schaufuss’s name in place of Spira-
linella, introduced by Chaster for this species, and accepted with
generic rank in the British List.
CampaniLe, Fischer, and CamPANILopa, gen. noy.
The former name was introduced by Fischer in the ‘‘ Manuel de
Conch.”’, p. 680, June 30, 1884, as of Bayle, with a diagnosis, ‘‘S.g.
Campanile, Bayle, 1884. Coquille trés grande, ete. . . . Opercule
typique (C. deve, Quoy et Gaimard, Australia). ... Les espéces
fossiles de ce groupe sont nombreuses dans |’ Eocéne (C. giganteum,
Lamarck) . . .”
The description of the operculum and the direct nomination of
C. lave, Q. & G., indicates that species as the type. If the fossils
differ they must bear another name. Cossmann later named
giganteum as type, and this was accepted by Bullen Newton, but the
latter agrees with me that the living shell has the best claim on
the name. As a matter of fact C. giganteum, Lamarck, cannot be
regarded as congeneric, because it is much more like TZerebralia
in every essential shell-character. As the living shells cover different
animals it seems inaccurate to associate the fossils with them, except
in direct lineage, and certainly C. gigantewm cannot be classed in the
326 PROCEEDINGS OF THE MALACOLOGICAL SOCIEVY,
recent genus Zerebralia without causing serious confusion. I there-
fore propose the new generic name Campanriopa for the species
Cerithium giganteum, Lamarck (Ann. Mus. Hist. Nat. Paris, vol. 111,
March, 1804, p. 439). It does not seem necessary to discuss the
relationships of this species since Cossmann has dealt so ably with
these in his memorable ‘‘ Essais’’.
With regard to the specific name of the sole species of Campanile,
I again find confusion. In 1834 Quoy & Gaimard introduced
a Cerithium leve (Voy. Astrol. Zool., vol. iii, pt. i, p. 106, pl. liv,
figs. 1-3, West Australia), and at the same time Griffith & Pidgeon
figured the shell under the name Cerithium truncatum. This was due
to a careless slip which was corrected in the Index to C. deve, Gray.
Thus it would seem a question which name has priority, but there is
on record an earlier use of the same name. Mathews and myself in the
Victorian Naturalist, vol. xxix, 1912, p. 11, noted the introduction
of Cerithium levis by Perry in the Arcana, pt. xv, 1810. I have
been unable to discover any synonym of the West Australian shell,
and therefore propose for it the name Campanile symbolicum. Since
Gray apparently proposed his name simultaneously with that of
Quoy & Gaimard I select as the shell requiring the new name that
specimen in the British Museum which was figured in Griffith &
Pidgeon, Animal Kingdom (Cuvier), vol. xii, Moll., pl. xiil, fig. 1,
with the name on plate Cerithiwm éruncatum. In the Index, p. 596,
1834, is written pl. xin, fig. 1, Cert’thiwm leve, Gray, with a note
‘* Erratum in the plate, Del. truncatum, lege leve”’, while lower
down is ‘‘ pl. xiv, fig. 4, Cerithtum truncatum, Lam.’? While Verco
used Campanile generally for this shell Hedley has more recently
adopted Ceratoptilus, Bouvier (Bull. Soc. Philom. Paris, ser. vit,
vol. xi, p. 86, 1887), but the latter is later in date and must fall as
an absolute synonym of Campanile.
PrevroromorpeEs, Bronn, vice Lora, Gistel.
In 1912 I noted in these Proceedings (vol. x, p. 225) that Zora,
Gistel, was proposed in 1848 for Defrancia, Millet, preoccupied, and
should therefore supersede Clathurella, Carpenter, introduced for the
same reason. As Gistel named in connexion with his proposal
a species not referable to Millet’s group a complication might have
ensued. It is obviated in one direction by the discovery that prior
to Gistel even, a name had been proposed for Defrancia of Millet,
for Bronn in the J¢al. Zertiar. Gebilde, 1881, divided the genus
Pleurotoma into two sub-genera, Plewrotoma, s.str., and Pleurotomoides
for ‘‘ Defrancia, Millet, non Brn.’? This was confirmed by Bronn
in the Lethea Geognostica, vol. ii, 1888, pp. 1062, 1064, where
he used Pleurotomoides (Defrancia). While this item disposes of
Defrancia, Millet, and its substitutes, it interests paleontologists
more than recent molluscan students, since I see no relationship
between the fossils grouped by Millet and the recent small species
classed under Clathurelia. Melvill has proposed Clathurina (antea,
p. 185) for a certain recent gronp, so that we have one name, but
Boettger had previously introduced Paraclathurella, etc. Hedley is
IREDALE: MOLLUSCAN NAME-CHANGES., 827
now engaged upon the Australian forms, and later I hope to develop
some points that have cropped up in this connexion. I might here
note that Jousseaume described in Le Naturaliste, 26th year, p. 106,
May 1, 1898, a new species Otitoma ottitoma { sic}, adding, ‘‘J’ai créée
le genre pour . . . Deshayes, dans son catalogue des mollusques de
Bourbon, a decrit trois espéces, Pl. reeveana, Pl. clandestina, Pl.
cyclophora, auxquels on doit joindre le Pl. vitrea, Reeve.’’ The
‘‘eyclophora”’ group needed a name, but elandestina might have
been called years ago by Melvill “a typical Clathurella”’.
GaABRIELONA, gen. nov.
I introduce this name for Phasianella nepeanensis, Gatliff & Gabriel
(Proc. Roy. Soc. Victoria, n.s., vol. xxi, August, 1908, p. 366, pl. xx1,
figs. 9-10), Flinders, Western Port, Victoria. The describers were
dubious as to the generic location, and I some time ago sorted out
a shell undoubtedly congeneric, from Lord Howe Island. I was
fortunate enough to recover live specimens showing the opercular
characters. Peculiarly enough the operculum is shelly, though of
quite a different nature to that of Phasianella, while the animal _has
been large and leaves a dead fringe round the mouth. I will return
to this point at a later opportunity, but here propose the above
name since the further account may be much delayed. I have just
received, through the generosity of Dr. W. G. Torr, a parcel of
shell-sand from Port Lincoln, South Australia, from which I have
separated a specimen, apparently nepeanensis, G. & G. While the
genus may be classed for the present in the family Phasianellide,
I do not think it has really any close relationship with Phasianedla.
The Lord Howe shells are sub-littoral in habit, so that the Australian
shell may be sought for in shallow-water dredgings. The occurrence
of the dead shell in shell-sand from South Australia indicates a sub-
littoral habit there. The recovery of live specimens and examination
of the radula will assist in classifying it, and a Naticoid affinity
suggests itself to me judging from the shell characters and the
operculum and dead animal of the Lord Howe species.
The genus is named in honour of Mr. C. J. Gabriel, whose energy
in connexion with the Victorian Mollusca is well known and
appreciated, and whose assistance to myself in many ways I wish to
commemorate.
ORBITESYELLA, gen. nov.
I propose this name and designate as type Cyclostrema bastowt,
Gatliff (Proc. Roy. Soc. Vict., n.s., vol. xix, 1906, p. 3, pl. 11, figs. 8-10,
Victoria). I also indicate it as representative of a new family
Orbitestellide, which is composed of a series of minute marine
molluses with the following characters: Shell thin, pellucid, dis-
coidal, dextral, of few whorls and of peculiar sculpture: widely
umbilicate, columella vertical, aperture never variced, irregular in
shape, edges thin.
I had hoped to describe the group, giving figures, but at present
this is impossible. I have species from various parts of New
328 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
Zealand, the Kermadecs, Lord Howe Island, Norfolk Island, New
Caledonia, Sydney Harbour, New South Wales, north coast of
Tasmania, and Port Lincoln, South Australia, in fact every austral
locality from which I have received a parcel of fine shell-sand or
fine dredgings. Commonly live shells have been secured when live
sand was received. All the species are very minute, and I have
about a dozen distinct species, divisible into two groups, and I hope
later to thoroughly elaborate the family with good figures.
Meeatuora, Pilsbry, vice Macrocuasma, Dall.
In the Proc. U.S. Nat. Mus., vol. xlviii, January 19, 1915,
Dr. Dall proposed Macrochasma as a new generic name (p. 439) for
Fissurella crenulata, Sowerby, a Pacific coast American shell.
Recently dealing with other Fissurellids, I noted that Pilsbry in
the Man. Conch., vol. xii, 1891, p. 182, quoted in the synonymy
of Lucapina crenulata, Sowerby, the name Degathura californica of
Nuttall MS. Under the present International Laws governing
nomenclature as exposed by the International Commission in
Opinion 4, the generic name JMegathura will supersede the later
Macrochasma, unless invalidated by some previous use of it. It
should be noted that no author can possibly protect himself against
such occurrences as this, as these MS. names have never been
recorded, nor previously legally recognized save in rare cases such as
the Leach names.
MirromorpnHa, auctt., non Carpenter.
This genus name has been generally accredited to A. Adams, and
has been used recently for a number of diverse species, both recent
and fossil, of which possibly not one is congeneric with Adams’
species. A peculiar confusion has been noted in connection with
this name, and [ had intended to define the generic terms I would
utilize in connection with recent Australian shells, but since I drew
up my notes my friend Mr. Charles Hedley has written me that he
is dealing completely with this group as regards Australian species,
so I withhold my say until my friend’s report has appeared.
Nevertheless I have certain information which he may not have
secured, and which it seems expedient tomake known. Inthe British
Assoc. Report for 1863 (published August, 1864), Carpenter included
(p. 658) ‘°? Daphnella + filosa, n.s., small, diamond-shaped, but
rounded periphery; spirally threaded. + Generic position .. .
doubtful: perhaps they belong to genera not yet eliminated; filosa
resembling the Eocene forms between Conus and Pleurotoma.” In
the Ann. Mag. Nat. Hist. (ser. m1, vol. xv, February, 1865, p. 182),
Carpenter fully described Mitromorpha filosa, recording that it was
the ? Daphnella filosa of the above entry, and observing, “Mr. A.
Adams obtained two similar species from Japan, and as the shells do
not rank satisfactorily under any established group, he proposes the
above genus for their reception. M. Crosse suggests that Columbella
dormitor, Sby., may be congeneric.”’
IREDALE: MOLLUSCAN NAME-CHANGES, 329
In the same place two months later (p. 322) A. Adams introduced
the genus Jlitromorpha with only one species, I/. lirata, nov., but he
referred to Carpenter’s usage of the name. This species, which has
been commonly cited as the type of Mitromorpha, is obviously not
generic with Carpenter’s shell, but I cannot explain how the mistake
arose. The Adamsian shell has not yet been figured, but I hope to
remedy this later when dealing more completely with the species
names. ‘The two species recorded by Carpenter were only classed as
varieties by Adams, but they are apparently valid species. Two
congeneric species have been figured, namely, Pleurotoma egrota,
Reeve (Conch. Icon., sect. Plewrotoma, Dec. 1845, pl. xxxi, sp. and
fig. 276, Singapore, 7 fathoms) and Daphnella crenulata, Pease
(Amer. Journ. Conch, vol. iii, Jan. 2, 1868, p. 221, pl. xv, fig. 20,
Paumotus), and I therefore propose ANTIMITRA, gen. nov., and name
Pleurotoma egrota, Reeve, as type. Adams’ Iitromorpha lirata is
conchologically referable to this genus.
When Pace dealt with Columbelloid shells he considered Carpenter’s
D. filosa as congenerie with Columbella dormitor, Sowerby, even as
Crosse had suggested, but gave no name to the group. Carpenter’s
Mitromorpha is now available. Pace also added here Conus atra-
mentosus, Reeve, and Conus parvus, Pease. The former was described
(Conch. Icon., sect. Conus, Suppt., June, 1849, pl. vil, sp. and fig. 265)
from Mindoro, Philippine Islands. I do not consider this congeneric
with JLtromorpha, and therefore propose Lovettona, gen. nov., with
this species as type. Several distinct species have been hitherto
confused under this name. Conus parvus was proposed by Pease
(Amer. Journ. Conch., vol. iv, Noy. 3, 1868, p. 126) as a new name
for Conus fusiformis, Pease (Proc. Zool. Soc. Lond., 1860, p. 898),
from the Sandwich Islands. Hedley has recently described Conus
micarius (Rec. Austr. Mus., vol. viii, 1912, p. 147, pl. xliii, fig. 32)
from Cape York, which he compared with Pease’s parvus. These
may both be classed in Lovellona.
Oliver named a Kermadec shell Mitramorpha [sic] expeditionis
(Trans. New Zealand Inst., vol. xlvii, 1915, p. 589, fig. 86), which does
not appear to be at all closely related to any named Turroid group, so
that I propose the new genus Apaturris for it. I have evidence
of other species in the Indo-Pacific area to be discussed later.
I anticipate that Hedley will not deal with the extra Australian
fossil species allotted to Mitromorpha, nor will I, but I would here
note for the benefit of paleontological workers that a heterogeneous
assemblage appears also to have been created in connection with the
name, and as Mitromorpha has now been shown to be untenable in
connection with the recent shells commonly so named it would be
well to rearrange the fossils without much consideration of the name
here given to the group which Adams’ species is referred to.
Catianaltis, gen. nov. for Satacta, Jukes-Browne, preoce.
When I wrote my Commentary on Suter’s Manual of the New Zealand
Mollusca (Trans. New Zeal. Inst., vol. xlvii, 1915, pp. 417-97),
I sketched a tentative classification of the Veneride of New Zealand,
330 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
based on Jukes-Browne’s results. In that place, p. 494, I included
with generic rank Salacia, Jukes- Browne, for the two species disjecta,
Perry, 1811, and yatet, Gray, 1835. Unfortunately I overlooked the
fact that Jukes-Browne’s name was invalid, having been used several
times previously. My mistake led Hedley to accept Salacia in his
List of West Australian Mollusca, so that rectification is necessary.
Jukes-Browne, simultaneously with his proposal of Salacia, added
Bassina for Venus paucilamellata, Sow. = alata, Reeve. I do not
know the exact relationship of this and the preceding, so propose,
with yatet, Gray, as type, the new name Cadlanaitis.
Awopsta, Gistel, vice Psycur, Rang.
The name Psyche was proposed by Rang, Ann. Sci. Nat. Paris,
vol. v, 1825, p. 284, but he had been anticipated by Schrank. In
Bronn’s Klassen Ordnungen Thierrerchs, vol. 11, 1862, p. 645, Kieferstein
proposed Halopsyche, for Psyche, Rang, non Linn., ete. Verrill accepted
Bronn’s correction, but Cossmann (Rev. Crit. Paléozool, 4th year,
Jan. 1, 1900, p. 43) introduced Verrillopsyche, since he found
TTalopsyche was also invalid. In this innovation Cossmann was
unfortunate, for even prior to Kieferstein, Gistel in 1848 (Naturg.
Thierr. Schulen) had corrected Rang’s error, proposing on p. xX
Anopsia for Rang’s Psyche, to make doubly certain, for on p. 174 he
had used Phelopseudes as a suitable emendation. It is noteworthy
that Gistel’s second thoughts came first, and that the correct name
appears to be Anopsia.
Hypromytes, Gistel, vice Evrrsra, Rang,
is an exact parallel to the preceding. Rang (Ann. Sci. Nat. Paris,
vol. xii, Noy. 1827, p. 328) proposed Huribia, years later than
Mergen (Nouv. Class. Mouches, 1800, p. 36). Kieferstein (loc. cit.)
corrected to Zheceurybia, which has been lately used. Gistel (loc.
cit., p. ix) had previously introduced //ydromyles, and in this case
was seemingly content withone choice. His name therefore replaces
Rang’s.

ON SOME NEW SPECIES OF MARINE MOLLUSCA FROM
CHRISTMAS ISLAND, INDIAN OCEAN.
By Tom Inrepate.
Read 8th June, 1917.
PLATE XIII.
Some years ago Mr. R. Kirkpatrick, of the British Museum, made
an expedition to Christmas Island, Indian Ocean, for the purpose of
securing living examples of a peculiar marine sponge. In this quest
he was successful after tedious and difficult dredging, and he brought
back a few samples of the sand dredged which have just recently
been handed to me for examination for small molluscan forms. The
results have been so extraordinary that I hope later, under more
favourable circumstances, to furnish a full account of them. I suggest
that 200-300 species are represented in the small quantity of sand
available, and many are of great systematic interest. I herewith
describe a few of remarkable aspect and unknown relationship.
These were all sorted from a parcel labelled ‘‘ Rich Foraminiferal
sand, with shells and corallines, 100 fathoms off North-East Point,
Christmas Island . . .”” The matter is all very dead, but a very
few live shells occur which are obviously living in that depth. I do
not consider that the majority of the dead shells had, however, lived
there, but had been washed down from less depths. In consequence
of this result Mr. Kirkpatrick handed over to me.a second parcel of
the same depth but another place, when most of the previously
recognized shells were again observed, with many additional forms.
Dr. C. W. Andrews, who made large collections at Christmas Island,
and upon whose researches the Monograph of Christmas Island
was based, has interested himself, and through his intervention,
which is here gratefully acknowledged, I hope to receive new and
better material whereby this most interesting fauna can be studied.
The peculiar novelties hereafter described may not be in any sense
local, but may be widely distributed throughout the Indo-Pacific
Region, as I have already noted species not hitherto recorded from
the Indian Ocean,
SHERBORNIA MIRABILIS, gen. et sp. nov. (PI. XIII, Figs. 1-4.)
Shell small, commencing life regularly as a dextral fusiform shell
with a short open canal, and upon approaching maturity developing
tubular apertures whilst the canal recurves. Thereafter, from the
oral aperture, two tubular apertures being persistent at the side
opposite and the canal being closed and left also as an aperture,
a shelly plate develops in concentric circles forming a platform.
This new genus is a further development along the evolutionary
lines of the Triphoridz, and has so many peculiar features that
I have no hesitation in proposing for it alone a new family
Sherborniide, which may temporarily be placed next the Triphoride,
but I do noé suggest that this is its true taxonomic position. I am

deeply gratified at being allowed to dedicate this peculiar genus to
my friend Mr. C, Davies Sherborn, of ‘Index Animalium” fame,
and I apply to the type (and at present only) species the trivial
name of mirabilis, an adjective I deem well applicable to my friend
also. The nucleus is dextral and glassy, consisting of one and a half
whorls, succeeded by strong rounded spiral liree which develop
nodules in some instances: the interstices are plain and there appears
to be no longitudinal sculpture. ‘The figures given show the
peculiarities of the shell better than a long description. The
peculiar specific features cannot be determined until congeners are
recognized. ‘he specimens are dead shells and pure white, which
seems to be the normal coloration. The complete immature shell
measures about 2 mm. in length, while the adult measures about
3mm. long; in breadth the platform increases the shell from
about 1mm. to 25mm. ‘The tubular apertures present features of
importance, though the accessory small tube puzzles the student as
to its function. From criticism of many of the Trituba group of
‘'riphoroids I am convinced they are parasitic upon living organisms
and use the tubes for circulatory purposes. The present genus
appears to have developed a plate in order to secure itself to its
host, but what the latter may be I cannot at present suggest:
perhaps it is some quickly moving object.
PIcKWORTHIA KIRKPATRICKI, gen. et sp. nov. (Pl. XIII, Fig. 6.)
Shell small, turreted, elongate triangular, base flattened, non-
umbilicate, mouth small, circular, surrounded by a very heavy varix.
This new genus I also consider representative of a new family
Pickworthiide, which may be placed alongside the Liotidée, but
as in the case of the genus just deseribed I would emphasize my
inability to pronounce exactly on its correct association, It might
be compared to a turreted ZLiotina, but really this would be only
a fanciful resemblance.
Type: Pickworthia kirkpatricki, sp. nov.
The apical whorls are minute, smooth, and three in number; the
adult whorls are sculptured with nodules, not arranged longi-
tudinally; the base is very flattened, and no longitudinal sculpture
is present. There is no umbilicus, but an umbilical depression is
observed bounded by a thick revolving spiral. he sculptured
whorls are seven in number.
The nodules appear in two rows to the whorl, an intervening
depression separating the rows; the suture between the whorls is
deep and marked; the number of nodules to the whorl varies from
twelve in the earlier to fifteen in the later ones.
There is no coloration present, the shell being white, vitreous, and
solid. The periphery of the last whorl developsa flange-like process,
and the nodulous sculpture becomes obsolete as the aperture is
reached, while on this last whorl a minor nodulous thread appears
between the two major rows. The base is flat, a revolving thread
below the peripheral flange being succeeded by a revolving spiral
rib which runs round the one bounding the umbilical region. The
IREDALE: NEW MARINE SHELLS FROM CHRISTMAS ISLAND. 333
mouth is small, circular, duplex, surrounded by the heavy varicose
extension which is angulate by the spiral sculpture of the last whorl.
The whole mouth system, including the varix, is so oblique that the
shell can rest upright upon the base.
Length about 4 mm., breadth 2 mm.
The only genus which I have studied with any care is Mecoliotia,
Hedley, but that is much smaller and umbilicate. I have not used
it, as in this collection I have several minute things which are not
congeneric with this species, yet seem nearer to Hedley’s genus, This
species is named after Mr. R. Kirkpatrick, who collected the sand ;
while the generic name is given in memory of Dr. Samuel Pickworth
Woodward, the distinguished conchologist, who may be spoken of as
the father of our science, since his Manual is the basis of the only
two later ones in existence, Fischer’s and ‘'ryon’s.
PickworRTHIA ANDREWsI, sp. nov. (Pl. XIII, Fig. 8.)
This species seems absolutely congeneric with the preceding, from
which it differs in its proportions and detail of sculpture. In the
type the apex is missing, but from immature broken shells classed as
conspecific it would be three-whorled, turbinate, and dextral. The
sculpture consists of nodules, increasing in size but not much in
numbers on the five adult whorls. Three rows of nodules are
present on each whorl, separated by a well-marked suture. The
upper two rows are smaller than the lower, the nodules rather
smaller and more or less connected so as to form indistinct retractive
longitudinals. On the last whorl this formation is distinct, so that
the upper two are almost continuous, while the lowest forms a basal
buttress, but not a flange-like process as in the preceding. The
nodules of this buttress are elongately continued so as to appear as
longitudinals from a basal view. ‘Ihe base is very like that of the
preceding, but lacks the post-peripheral thread, while the succeeding
spirals are stronger and the umbilical depression is deeper. ‘The
varix is not so developed, though similar.
Length, without apex, 2°5 mm.; breadth 1:5 mm.
The species is named after Dr. C. W. Andrews, the pioneer
collector of mollusca from this locality.
REYNELLONA NATALIS, gen. et sp. nov. (PI. XIII, Fig. 7.)
Shell small, elongate, rather conical, base rather flattened, aperture
contracted to a small circular opening with duplex, but not varicose,
peristome. Again I would introduce a new family, Reynellonide,
which could be placed near the Pickworthiide, but this is mere
conjecture. It bears a fanciful resemblance to the figure of Hyvelissa
formosa, Lycett, given in Fischer’s ‘‘ Manuel’’, p. 6838, fig. 451,
from the ‘Terrains jurassiques”’, which was placed in the family
Cerithiide.
Type: Reynellona natalis, sp. nov.
Apical whorls two, dextral, smooth, sueceeded by seven whorls
sculptured with retractive slanting ribs, which do not increase much
in number, but the smooth spaces between become enlarged with the
234 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
growth of the shell; thus eleven may be counted on the third whorl,
while there are only fourteen on the last; these ribs are prominent,
rounded, and not continuous from whorl to whorl. The earlier
whorls slowly increase, but at the antepenultimate the increase
becomes more rapid, at the last, however, rapidly contracting in
the descent to the unvaricosed aperture. The base is sculptured
with five deep incisions separating five rounded spiral lire. There is
no umbilicus. The mouth is circular, strongly oblique to the axis,
duplex, but not varicose.
Length about 3mm., breadth 1°5 mm.
I have named this genus after my friend Mr. Alex. Reynell, whose
help with regard to literature is again acknowledged.
ANXIETAS PERPLEXA, gen. et sp. nov. (Pl. XIII, Fig. 5.)
Shell minute, conical, base flattened, mouth somewhat quad-
rangular, edges thin, columella simple, imperforate.
Type: Anaietas perplexa, sp. nov.
This peculiar little species gives no clue to its affinities in any
way, and I place it in the Trochide with considerable reserve, but
it has no striking feature whereby it can otherwise be determined.
Shell conical, top flattened, sides rounded, almost unsculptured.
Colour pale brownish yellow, a darker line at the sutures. Five
whorls may be counted, of which the apical two form a planate
nucleus, the succeeding three rather rapidly descending but tightly
wound with no umbilicus. Below the periphery of the last whorl
on the base appear a couple of incised lines close together, but no
other sculpture seems present, save a similar incised line above the
periphery, which is seen parallel to the suture on the three post-
nuclear whorls. Columella simple, erect, a little curved. Aperture
oblique, edges thin. Height 1:5 mm., breadth 1 mm.
The names given to this shell express my opinion regarding it.
One live shell was recovered, proving that it lived at this depth,
with several dead ones. It resembles no juvenile 'rochoid I have
examined, and that comprises a fair number. —
I may observe that these descriptions may be regarded as more or
less provisional, subject to extension upon receipt of better
material and more species. In any case I hope to furnish with
any further detailed account additional figures elaborating the
peculiar points of the species.

ANNUAL GENERAL MEETING.
Fripay, 8ruH Frprvary, 1918.
J. R. LEB. ToMuin, M.A., F.E.S., President, in the Chair.
Mr. H. C. Fulton and Mr. C. Oldham were appointed scrutineers.
The following report was read :—
“In presenting their twenty-fifth Annual Report your Council
have much pleasure in again recording a year of continued progress.
The papers printed during the past year have maintained their
general standard of excellence.
‘‘It is with deep regret your Council have to record the loss by
death of two members: Mr. G. C. Crick, F.G.S8., F.Z.S., and Dr. IT. H.
May; while four members have resigned.
‘During the year six new members have been elected, so that the
membership of the Society on December 31st, 1917, stood as
follows :—
Ordinary members. ¢ . : : 66
Corresponding members 5 c : : 84
Total . = 00
‘It is to be regretted that the financial position of the Society is
unsatisfactory and calls for immediate attention. Although the
year ends with a balance of £41 16s. 3d., liabilities to the amount of
£40 Os. 8d. have to be immediately met, so that only a sum of
£1 15s. 7d. is available with which to commence the year. Our
heavy printing accounts, now encumbered with an extra war charge
of 30 per cent, and the other expensive items, are unable to be fully
discharged within the year on the present low membership fee.
Suggestions will, therefore, be placed before members as early as
possible to consider the desirability of increasing all annual sub-
scriptions and entrance fees, and thus endeavouring to place the
Society upon a sounder financial basis.
‘We still hold £50 Metropolitan 23 per cent stock.
‘The usual three parts of the ‘ Proceedings’, Parts 4—6 of Vol. XII,
with title-pages and index completing the volume, were issued in
May, August, and November respectively. They comprise 217
pages of text, illustrated with 7 plates and 14 sets of text-figures.
‘The following authors have very kindly assisted in the cost of
these illustrations, or have furnished drawings, photographs, or
blocks for reproduction: H. H. Bloomer, H. Overton, E. W. Bowell,
Dr. A. E. Boycott, Rev. Dr. A. H. Cooke, the late G. C. Crick,
H. ©. Fulton, C. Hedley, T. Iredale, Dr. J. Cosmo Melvill, and
G. B. Sowerby.
‘A portrait of our late Treasurer, J. H. Ponsonby-Fane, was
subscribed for and presented by: T. Iredale, A. S. Kennard, Dr. J.
Cosmo Melvill, R. Bullen Newton, A. Reynell, A. E. Salisbury,
E. R. Sykes, J. R. Le B. Tomlin, and B. B. Woodward.
‘‘Further, the thanks of the Society are again especially due to
the Council of the Linnean Society, through whose kindness it has

been permitted, since the year 1894, to hold its meetings in
Burlington House.”
On the motion of Mr. A. S. Kennard, seconded by Mr. Tom
Iredale, the foregoing was adopted as the Annual Report of the
Society.
The following were elected Officers and Council for the year
1918 :—

J.R. LE B. Tomiutn, M.A., F.E.S., President, in the Chair.
Mr. Percy T. Deakin was elected a member of the Society.
The President delivered his Annual Address entitled ‘A
Systematic List of the Fossil Marginellide”’.
Mr. R. Bullen Newton proposed, and Mr. H. O. N. Shaw
seconded, a vote of thanks to Mr. Tomlin for his Address, and
requested him to allow it to be printed tn ewtenso in the Society’s
Proceedings.
ORDINARY MEETING.
Frmay, 8rH Marca, 1918.
R. BULLEN NEWTON, F.G.S., Treasurer, in the Chair.
The following communications were read :—
1. ‘On the generic position of Zemira, H. & A. Adams.” By
the Rev. Dr. A. H. Cooke, M.A., F.Z.S.
2. ‘Ona new variety of Anodonta anatina (L.).” By Percy TY.
Deakin. The author described the peculiar features of three half-
grown specimens of Anodonta anatina found among some hundred
or more individuals taken alive from a pond at King’s Norton,
Worcestershire, in the autumn of 1916, in company with A. cygnea
and Unio pictorum. These three examples showed, on aground colour
of dusky-olive, rays of a different tint, which coincided with raised
lines or ribs, and the author proposed to accord them varietal rank.

Sicily.
SPECIAL MEETING.
Fripay, 12tH Aprit, 1918.
The Rev. Dr. A. H. COOKE, M.A., F.Z.S., Vice-President, in the Chair.
The meeting was convened by the Council for the purpose of
submitting the following resolution :—
‘That in order to meet the increased cost in the production of the Society’s
publications, for which the present income is inadequate, the annual subserip-
tion to the Society shall be in future one guinea for ordinary members and 15s.
for corresponding members; the composition fees for life members shall be
ten guineas and seven guineas respectively ; and the entrance fee shall be one
guinea. Members elected prior to the passing of this resolution shall be
invited to strengthen the financial position of the Society by voluntarily
adopting the increased subscription; but failure to do so shall not prejudice
the standing of any such member.’’
The resolution was formally moved by Mr. A. S. Kennard and
seconded by Mr. A. E. Salisbury. After some discussion by various
members the following amendment was moved by Mr. C. Oldham,
accepted by Mr. Kennard, and carried unanimously :
““To substitute for ‘in future’ the words ‘ for the year 1919 and after’.’’
The Secretary then moved on behalf of Mr. E. F. Wesley, and
Mr. H. O N. Shaw seconded, the following resolution :—
‘“ That the price to the public for single parts shall be raised to 10s. The
price of back numbers to remain the same, and that members of the Society be
allowed to purchase extra copies of any numbers at 25 per cent discount from
the published prices.’’
The Council’s resolution, as amended, and Mr. Wesley’s resolution,
were then put to the vote and carried unanimously.
ORDINARY MEETING.
Frinay, 12TH Aprit, 1918.
The Rey. Dr. A. H. Cookk, M.A., F.Z.S., Vice-President, in the Chair.
Five candidates were proposed for membership.
No communications were read.
ON THE RADULA OF THE GENUS ACANTHINA, G. FISCHER.!
By the Rev. A. H. Cooxg, Sc.D., F.Z.S.
Read 9th November, 1917.
Tur genus Acanthina is peculiar to the west coast of America,
ranging from Bolinas Bay in the north to Cape Horn and round to
the. Falklands in the south. ‘The species hitherto known under the
name fall into three geographical groups.
1. The northern, comprising paucilirata, Stearns, punctulata,
Sowb., and wnicarinata, Sowb., and extending from Bolinas Bay to
San Diego.
2. The central, with brevidentata, Wood, grandis, Gray, and
muricata, Brod., ranging from Lower California (point unknown) to
Paita, including the Galapagos.
3. The southern, with calear, Martyn, and crassilabrum, Lam.
(many unite the two as one species), ranging from Peru southward,
round to the Falklands. A. dugubris, Sowb., whose northern limit
is Todas Santos Bay, San Diego, but whose southern range is not
precisely known, though it reaches the Galapagos, forms a connecting
link between the northern and southern groups.’
P. Fischer (Manuel de Conchyliologie, p. 646) remarks: ‘‘ Les
Acanthina ne sont en réalité que des Purpura et peuvent étre divisés
en sections correspondant a celles de ce genre par leurs principaux
earactéres. L’A. lugubris, Sowb., est un Zhalessa, A. crassilabrum,
Lam., un Polytropa, VA. muricata, Brod., un Planithais, ete., les
exemples montrent que le caractére tiré de la présence d’une dent au
labre est tout a fait artificiel et sans valeur.”
There is much to be said in favour of the view contained in the
last sentence quoted. But the additional evidence drawn from an
examination of the radula tends to show that the different
geographical groups of Acanthina, as laid down above, exhibit well-
marked differences in the structure of this organ, that accentuate
the obvious dissimilarity of the shells. Viewed in this light the
northern and southern groups stand apart from one another, while
the central group, or what remains of it, differs strongly from both,
if it does not disappear altogether. ‘The affinities of A. lugubris,
Sowb., lie with the southern group. From a conchological point of
view one would have expected this to be so. The more globular
form and wide mouth, and also the very prominent tooth of lugubris,
bear more resemblance to the forms of calear and crassilabrum than to
the narrow long-drawn shape of the Upper Californian , pp. 441-480.

THE INDEX TESTACEOLOGICUS OF W. WOOD & S. P. HANLEY.
By A. Reyne tt.
Read 11th January, 1918.
Concernine the history of the first edition of this book published in
1818 there is not much available information. Dillwyn’s ‘‘ Descrip-
tive Catalogue” had appeared a few years previously, and Wood
remarks in his preface that his own ‘‘ Index” is a list of names
merely and not a descriptive index.
1 With temporary title, dated 1851, list of contents.
2 With a general index, title-pages, and list of contents to each of the four
volumes.
REYNELL: wooD & HANLEY’S INDEX TESTACEOLOGIOUS. 27
Copies are found both with and without plates, eight in number
when present, Wood appearing to catalogue only the unillustrated
edition, which he prices in his own book catalogue at 9s.
Férussac criticized the book favourably in a paper published in
the Journal de Physique (t. xc, 1820, p. 292),
The second edition of Wood’s Jndex is dated 1825. It was,
however, really issued in two parts: pp. vil and viii, 1-64 with plates
1-13 were issued in or before June, 1823. (I havea copy of the
first part as issued with the subscriber’s name, Anne Elizabeth
Gregory Williams, and date, June, 1823.)
This first part contains a temporary index to the figures and a
mention that the second part will be issued in the year following,
but it was delayed until 1825. The complete edition contains a list
of subscribers’ names, as well as a table of errata.
In 1828 Wood republished his book with additional references,
but minus the list of subscribers and table of errata, and an enlarged
list of authorities, calling it the ‘‘second edition’’ (in reality it is
the third). Later in the same year he published a ‘‘ Supplement”’
of 59 pages with eight additional plates and a preface.
This finished W. Wood’s connection with the book except as
publisher.
S. P. Hanley, recognizing the usefulness and convenient size of the
work, turned his attention thereto, brought it up to date as regards
nomenclature, and at the same time added an appendix dealing with
bivalve shells, which latter appeared in parts between 1842 and 1856.
Hanley himself, in the preface to the completed appendix, dated on
title-page 1842-1856, gives the dates approximate only in most cases
of the appearance of the different parts as set out below.

It seems appropriate to initiate some general title for articles such
as I have been lately contributing to these Proceedings, and hope to
continue to do. The solutions in many cases are comparable to that
applied to the Gordian Knot, and I may hereafter find that in this
method I have been anticipated. In a similar case reproach was
IREDALE : MOLLUSCAN NOMENCLATURAL PROBLEMS, 29
levelled at the worker, but at the present time I conclude it is the
only means of making progress. Thus, quite recently, I published
some notes giving the correct names as determined at that time: such
decisions were based on my own results, confirmed by the usage of
such specialists as Dall, Hedley, Cossmann, etc., yet continuing my
investigations I find further corrections necessary, and the case of
Eumeta herein given may be quoted as an example, while I have
others under consideration, such as Azor.
Tritonta, Cuvier.
As introducing a number of nomenclatural complexes the genus
name Z?yitonia furnishes a good example. The first introduction of
this name seems to be that of Cuvier in the Tabl. Elém. Hist. Nat.,
Jan. 1798, p. 387, where a genus is diagnosed but no species are
named in connexion. The name 7r7toniwm had been proposed at an
earlier date. Under the usage of British workers the later name
should be discarded, but in this case for some unknown reason the
practice was not followed. In1801 Lamarck accepted the Cuvierian
name and gave as example the species clavigera, Miiller (Syst. Anim.
s. Vert., p. 65, Jan.). According to the International Rules this
must be accepted as the monotype of Cuvier’s genus, but I cannot
understand the ruling, while in this case Cuvier later noted that
clavigera, Miiller, might be regarded as a member of the genus, but
no certainty was expressed. However, in 1800 Meigen correctly
proposed the name Zritonia for a genus of Insects: the point is, does
the Cuvier—Lamarck name, 1798-1801, anticipate Meigen, 1800?
In the Ann. Mus. Hist. Nat., Paris, vol. i, p. 483, April, 1803,
Cuvier fully diagnosed his genus Zritonia, illustrating a fine new
species, Z. hombergi, and this has gained avceptance as repre-
sentative of Zritonia and of the family Tritoniide. Lamarck’s
selection, although prior, was dismissed as not being that of Cuvier,
and the name Zriopa proposed by Johnston (Ann. Nat. Hist., vol. i,
p- 123, April, 1888) for clavigera, Miller, has been used instead. It
may be noted that the two species hombergi and clavigera belong to
very different families. If the Cuvier-Lamarck name be accepted it
would displace Zriopa. Several substitute names are on record.
Euphurus was proposed for Tritonia, Lam., by Rafinesque (Anal.
Nat., 1815, p. 142), while Gistel, in 1848, introduced Necromantes and
LInriope for Tritonia, Cuvier, mentioning hombergi in the latter case.
However, in 1843, Macgillivray had described a new species and
genus, Spherostoma gamesonit (Hist. Moll. Anim. Aberd., pp. 335-6),
which has been identified with Zritonia hombergi, Cuvier.
Under these conditions I suggest the rejection of Z)itonia, Cuvier,
as being preoccupied by Zritondwm, Miiller, 1774, and thus remove
a most perplexing and unsatisfactory problem from Nudibranch
nomenclature.
Then Huphurus, Rafinesque, would be available for the genus now
called Zriopa, and Spherostoma, Macgillivray, for the one now bearing
the name Zyitonia, Cuvier, and of the latter Vecromantes and Liriope,
Gistel, would be synonyms. I give a full list of Gistel’s names later.
30 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
Dorona, gen. nov. for Melibea fragilis, Forbes.
In other ways than the preceding, Nudibranch names show
confusion, and I propose Dotona for the species Melibea fragilis,
Forbes (Malac. Monensis, 1838, p. 4), the genus name Doto quoted as
of Oken, 1815, having been used in 1807 by the same author in
a different sense.
Galvina, Alder & Hancock, is in use for a group of which one
species is the monotype of Hubranchus, Forbes, 1838 (loc. cit.),
which has priority. Many more instances of this character occur,
the case of ZLomanotus, Verany, being on a parallel with Zritonia,
Verany’s name, 1844-6, being intercepted by Humenis, Alder &
Hancock, 1845, which has been rejected.
Lasxerya, nom. nov. for Humeta, Morch, 1868.
Recently I concluded that Humeta was the valid generic name for
a British shell, because the name had been accepted by Thiele, Hedley,
ete. I overlooked the fact, as my co-workers had done, that it was
preoccupied by Walker. I ‘therefore propose Laskeya, nom. nov. for
Eumeta, Morch, 1868. I would note that Locard introduced Cerithio-’
linum (Ann. Soc. Agric. Lyon, ser. 11, vol. x, 1908, p. 110) as a new
name for Lovenella, Sars, 1878, about twenty years too late.
Cottonisra, gen. nov. for Collonia picta, Pease.
The genus name Collonia has been discussed and is now relegated
to fossils agreeing with the type. ‘There seems to be a recent group
having much the same features. Leptothyra proves to have been first
published by Pease in connexion with a juvenile shell of a different
genus. The matter is complex and needs careful handling, but
I here remedy one item by the above proposition.
TALOpENA, gen. nov. for lonzlea incerta, Iredale.
Under the name Jonilea many different shell groups have been
confused, and when E. A. Smith pointed out that Swainson’s
description negatived his tentative reference of his type to ‘‘ callifera,
Lam.’’, he used Solariella, S. V. Wood. That name given to a Crag
fossil should not be used in connexion with recent shells showing
unlike shell characters. Gray proposed Zalopia, apparently for the
callifera group, but without diagnosing it, and later cited it as
a synonym of Donilea, Swainson, giving callifera, Lam., as type of
the genus. Consequently, I conclude Zalopia would become valid
for the callifera group. This, however, is not congeneric with the
austral species commonly referred to Monilea, and two other names
have been cited in conjunction with them.
Minolia, A. Adams, and Conotrochus, Pilsbry, the latter afterwards
being considered by its author as synonymous with the former.
Since the last-named is an invalid name, certain corrections seem
necessary.
I herewith propose Zalopena for Monilea incerta, which I described
from the Kermadecs, and which is typical of a well-marked austral
series.
IREDALE : MOLLUSCAN NOMENCLATURAL PROBLEMS. 31
Korovina, gen. noy. for Vanikoro wallacei, Iredale.
When I named Vanikoro wallacec in these Proceedings from the
Kermadecs I commented upon the opercular characters, which
disagreed with those given for the genus Vanikoro by H. & A. Adams.
Mr. Hedley informs me that he has a note upon the invalidity of
Vanikoro, with which I agree, so I now propose Korovina for my
Kermadec species.
ForskaLena, gen. nov. for Zrochus fanulum, Gmelin.
H. & A. Adams introduced Forskalia in the Gen. Rec. Moll., vol. i,
p. 432, June, 1854, for Zrochus declivis, Forskal, fanulum, Gmel., ete.
The previous year that name had been given by Kolliker (Die
Schwimmpolypen von Messina, 1853, p. 2) to a Colenterate.
I perpetuate the dedication by alteration to Forskalena, the second-
named species being designated as type. I conclude Forskal was
not a binomial writer, so that his species names cannot be legitimately
used; since his work was published after his death, the names
selected may have simply been preliminary latinized descriptive
terms.
Eniemonia, gen. nov. for Anomia rosea, Gray. ,
As a rare and peculiar North Australian mollusc, Anigma
anigmatica (Chemn.) has been cited. The correct name of the shell
proves as perplexing as this combination reads, since it seems neither
generic nor trivial name can be maintained. -4nigma is credited to
Koch, 1846, the quotation (incomplete) referring to Martini & Chemn.,
Cont., lief. 56, band vii. I have been unable to trace this. My
earliest reference is to the quotation by Gray in the Proc. Zool. Soc.
Lond., 1849, p. 114, as a MS. name in the cabinet of Mr. Cuming.
It was probably so published at the earlier date. However, in
April, 18386, E. Newman had published 4/nigma in the Entom. Mag.,
ser. III, vol. v, p. 499, for a beetle.
Tellina enigmatica, Chemnitz, cannot be used because that author
was non-binomial, and according to Sherborn’s Index Animalium
that name was not binomially used before 1800. I have not seen it
legitimately employed until 1837, while in Thomson’s Annals of
Philosophy, N.s., vol. ix, Feb. 1825, p. 189, Gray had introduced
Anomia rosea for the species figured by Chemnitz, vol. x, pl. 199,
figs. 1949-50. Gray’s type is in the British Museum.
Amyctina, gen. noy. for Buceinum corniculum, Olivi.
Some years ago I pointed out that Amycla, H. & A. Adams, was
invalid, and, since I have seen no rectification in the meantime,
I propose the new genus Amyclina for Buecinum corniculum, Olivi.
Pyreneoxa, gen. nov. for Columbella abyssicola, Brazier.
I have already noted the distinctness of this genus without naming
it, so here provide the above name, because the group is more or less
known, and I cannot as yet publish the full account.
Caporsis, Bartsch.
Bartsch, in an essay on South African Marine Molluscs (Bull. U.S.
Nat. Mus., No. 91, 1915), introduced the name Caporbis (p. 170) in
32 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
the family Vitrinellide. The good figures showed it to be the
nucleus of a Vermetid, and Mr, J. R. Le B. Tomlin has recovered
examples showing the nucleus perfectly.
Propeseta, gen. nov. for Murex turricula, Mont.
The above name is proposed because the species selected as type is
not congeneric with those recently associated under Bela, and the
correct generic name of which is Oenopota, Morch. Most recent
authorities have agreed with this conclusion, but have not rectified
the error. :
CatcroLata, nom. nov. for Calceolina, A. Adams.
A. Adams (Ann. & Mag. Nat. Hist., ser. 111, vol. xi, April, 1863,
p. 267) introduced a genus Calceolina, writing, ‘‘ This little genus
is established on a shell I found at Tanabe, and which I believe to
be the same as the Neritina pusilla of C.B. Adams.” The genus and
species were then described, and since the generic name had been
anticipated by Rafinesque almost fifty years before, and the species
is not that of C. B. Adams, I introduce the new generic name
Calceolata, while the new specific name will be anomala.
Microruyca stands instead of Ificrotheca.
Two pages earlier A. Adams (op. cit.) proposed Microthyca, and this
was altered to Mrerotheca, and has since commonly been so spelt; in
the latter state it is invalid, so that reversion must be made to the
first spelling, otherwise a new name would be necessary.
Turrip Group Namus.
Dr. Dall has recently published (April 5, 1918) two extremely
valuable papers in the Proc. U.S. Nat. Mus., vol. liv, entitled
“¢ Notes on Chrysodomus and other Mollusks from the North Pacific
Ocean” (pp. 207-34), and ‘‘ Notes on the nomenclature of the
Mollusks of the family Turritide”’ (pp. 3138-33). Both are really
beyond criticism, and the points I here deal with are comparatively
trivial, but are offered to complete the cases and draw attention to
such items.
The latter is a most complete list of sectional names, and though
I have been noting these for some years, I can scarcely make any
additions save with regard to incomplete references. Dr. Dall’s
complete work will be a most invaluable aid to the student of these
most puzzling forms, and I anticipate many more sections in
connexion with the small Indo-Pacific species, the nuclear characters
showing diverse origin in conchologically similar shells, the differences
observed being radical, such as the contrast being a highly sculptured
“ Sinusigera’’ and a bulbous one-whorled smooth turn.
Thus, Zomopleura, Casey, is a well-marked and distinct group
which Dall, in one place, refers to Zurris, s.str., and then to Zeres,
with neither of which canit be confused, while these are very different
from each other.
Dall has not seen the paper in the Nat. Sicil., an. ix, May 1,
1890, in which Monterosato proposed Smithiella, p. 186, Villiersiedla,
p. 191, and published Zeretia, p. 187, that name previously appearing
only in a privately printed manuscript.
IREDALE: MOLLUSCAN NOMENCLATURAL PROBLEMS. 335
The rejection of Clionella, Gray, 1847, in favour of Melatoma,
Swainson, 1840, seems to need reconsideration, judging from
Swainson’s figure, since the South African Clionella has a short
canal quite unlike the long canal indicated by Swainson. I purpose
tracing Swainson’s type, and in the meantime counsel the retention
of the certain name Clionella.
Zafra certainly does not seem referable to this family, but I suggest
we are confusing several “ families’? through the influence of the
posterior canal. For instance, from the figure, Schepman’s
Daphnellopsis is a close relation to the groups Dall separated as
Maculotriton, etc., the canal in this case being the one seen in the
Bursa family, and not of Turrid significance.
Cottcryprus, gen. nov. for Buccinum fusiforme, Broderip.
When this paper was read I had written Colieryptus for Buecinum
fusiforme, Broderip. Since then I received Dall’s ‘‘ Notes on
Chrysodomus”’, in which I see he still retains Aryptos, Jeffreys, and
says, ‘‘ Fusus fenestratus, 'lurton (+ fusiforme, Broderip, + Broderipit,
Jeffreys) probably belongs to this genus.” Dall thus confirms
Dautzenberg & Fischer’s usage, who claim priority for the first
named, indicating also the latter has been anticipated by Kiener,
1834. Their statement is, however, incorrect, since Broderip’s name
dates from 1830, not 1835, as given by those authorities. usus
Susiforme has not much likeness to the other members of the group,
and I reject Aryptos as preoccupied by Cryptus, a logical conclusion
under the International Rules for Nomenclature. I also introduce
the new name
SIPHONORBIS MARSHALLI for Fusus attenuatus, Jeffreys,
which is preoccupied by usus attenuatus, Philippi (Paleeonto-
graphica, Bd.i, pt. 1, March, 1847, p. 72), while I suggest that
Marshall’s Fusus consimilis is founded on a specimen distorted by
fracture.
I am quite unable to understand the reason of Dall’s rejection of
Neptunea, Bolten, in favour of Chrysodomus, Swainson, for these
whelks, seeing that the former is absolutely valid and has been
current for many years without question.
It is strange to find so doughty a champion of Boltenian names
and stalwart a protagonist of selection of type by elimination calmly
throwing over both with the callous remark (p. 214), ‘‘ The name
Neptunea, Bolten, was given to a heterogeneous collection now
‘divided into eight or more genera of several distinct families.”
CoMINELLA AND EvraRia DISCUSSED.
I had drawn up some notes on the species classed under Cominella
and uthria, when the Rev. Dr. A. H. Cooke informed me he
was engaged upon the examination of the radule of these groups,
I therefore withheld my notes until his work was completed. It is
worthy of emphasis that his results coincide more or less with my
own conclusions based on shell eharacters, proving once more the
concordance of external and internal features. Some of Dr. Cooke’s
VOL. XIII.—AUGUST, 1918. 3
34 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
conclusions, based on published accounts, need reconsideration, as
for instance ‘‘two (species) at least of which are also found in
Australian waters’’. This refers to Neozelanic species and the two
cited ‘‘ costata, Quoy, lineolata, Lam.” are not truly Neozelanic.
I determined a dead shell as referable to the first named, but I am
sure now that was a mistake. Neither does the genus occur at the
Kermadecs as given by Suter. It is remarkable that one of the
radule figured by Dr. Cooke (ex Gwatlkin coll.) should have been
named as ‘‘ costata, Quoy: New Zealand’’, and I cannot recognize to
what it really belonged. The genus name Cominella was proposed
by Gray in 1850 (Fig. Moll. Anim., vol. iv, p. 72), the species
attached being testudinea, maculosa, etc., and the first-named figured.
J here designate that_as type. As shown by Dr. Cooke, the radule of
the Austro-Neozelanic species are similar in type and consequently
shell characters have to be considered. The costata—lurida group
show a constant shell formation very different from adspersa, maculosa,
and virgata. These last three differ among themselves, and a more
detailed examination will probably result in their separation. At
the present time I propose to deal with the South African‘‘ Cominella”’,
which are readily separable by shell characters and whose radule are
remarkably different. The exact names of these species will be
dealt with later, but I introduce Afrocominella for elongata, Dunker,
and tigrina, Kiener, designating the former as type, and propose
Burnupena for the peculiarly distinct group, delalandii, Kiener,
lagenaria, Lam., Jimbosa, Lam., and porcata, Gmelin, designating the
last named as type, while pointing out that the species name is
preoccupied and that it should be ezneta, Bolten (Mus. Bolten, 1798,
p. 118), proposed for Martini, 4, t. 126, figs. 1218-14. So that the
type name stands Burnupena cincta (Bolten).
With regard to the radula of Luthria, Dr. Cooke has shown that
diverse groups have been confounded’ under this name, a fact
communicated to me by Professor Gwatkin many years ago. Cooke
places the Neozelanic dinea, Martyn, with the European corned, L.,
the type of the genus: the radula is somewhat different and the shell
decidedly so, that I revive for it the genus name Lvarne, proposed by
BS 165A. Adams, but afterwards ignored. The other Neozelanic
species cannot be classed with /inea, so I introduce the name Luthrena
for them, naming vzttata, Quoy & Gaim: ard, as type.
The extraordinary radula presented by ferrea, Reeve, from Japan,
proves at once that this species is no relation to either the European
Euthria or the Southern so-called Huthria. In order to attract
attention I propose Japeuthria for Reeve’s species alone. Cooke
shows by means of the radule that the Magellanic species of Huthria
belong in reality to Comnella, a fact i pointed out to Messrs.
EK. A. Smith and H. B. Preston some years ago from consideration of
conchological features alone.
SyntTaGMA, nom. nov. for Donovania, B., D., & D.
In an essay on Crustacea in Brewster’s taisbaeck Encyclopedia,
vol. vii, 1814, Leach proposed the generic names Donovania (p. 485),
IREDALE : MOLLUSCAN NOMENCLATURAL PROBLEMS, 35
Montagua and Mulleria (p. 436). All these-three were later intro-
duced for molluses, the first and last still being used, the second one
rejected on different grounds.
The first-named has been constantly used since 1882, and has no
valid synonymy, so I name the genus Syntagma, the species Buccinum
brunneum, Donovan, being retained as type. The genus is included
by Dall in his list of Turritide, without comment, though years ago
M. Woodward showed that the radula was buccinoid.
Acostma, Orbigny, will replace DMulleria, Férussac, 1823.
As above noted Dulleria can no longer be used for the well-known
freshwater Oyster, but there is a ready-made alternative, Acostea,
Orbigny, 1851 (Rev. & Mag. Zool., sér. II, tom. iui, p. 184), available
for use.
Gistret’s Mottuscan Generic Names, 1848.
In a book entitled ‘“‘ Naturgeschichte des Thierreichs fiir Schulen”’,
published in 1848, Gistel introduced a large number of corrections (?)
of invalid names, and these escaped note for some time, probably
through carelessness, as H. & A. Adams cited many of them in their
‘‘Genera of Recent Mollusca’. The names are recorded in “two
places: firstly, in a prefatory discussion on preoccupied names, and
secondly, in the body of the work. ‘The former list was obviously
compiled as an after-thought, and frequently Gistel has named the same
thing twice, and just as often used the same name twice in different
connexions, while he very commonly selected preoccupied names in
his corrections. Since the book is not well known and the names
may need consideration, I give a list of the Gistel innovations, as

I have already drawn attention to Zora, Anopsia, Hydromyles,
Charonia, and would here note that Hyperva and Herse, both provided
for Cuvierta, were each invalid, but such a name as Hemanis may
later be called into use. If a substitute for Glaucus be needed
Dadone must be considered, while the two substitutes for Cavolinia as
used by Eschcholtz & @Orbigny need criticism, but as Fabius is
invalid neither may claim usage. The consideration of the preceding
confirms my conclusion that all are absolutely substitute names, and
can only be determined as such, and consequently the mention of
a species cannot legitimatize Gistel’s name in that connexion as
opposed to its substitution value.
Damontetta, gen. nov. for Bulla cranchi, Fleming.
In the Proc. Zool. Soc. Lond., 1847, p. 161, ‘‘ Rorania, Leach
MSS.,1819. Bulla eranchii’’ was given by Gray. This was published
in November, but in the October number for the same year of the
Ann. & Mag. Nat. Hist., vol. xx, p. 268, the name had been printed
as ‘‘ Roxania cranchit”’, which twenty years before Turton, in the
Zool. Journ., vol. ii, p. 566, 1826, had recorded from Torbay and
Scarborough. However, Bulla cranchii was not described until 1828,
when Fleming gave an account in his Hist. Brit. Anim. (ante April 1),
p- 292, from specimens received from Leach procured at Plymouth
Sound. Leach was apparently distributing species under his generic
names to different people, and, moreover, different species were
confused. Thus Lamarck described Bulla cornea from specimens
received from England, citing as a synonym Bulla erancki, Leach.
This species has been identified as Bulla hydatis, Linné, which seems
to invalidate the specific name. Then in the Mag. Nat. Hist.
(London), vol. vii, p. 852, July, 1834, Turton described Bulla
hyalina, citing in association with it the genus name oxania, Leach
MS. ‘his seems to be the earliest legitimate use of the name.
Since this species is quite unlike the usually accepted one, it is
fortunate that Stephens had previously proposed Roxana for a genus
of Iepidoptera.
There is no necessity to quibble as to whether Rowania and Roxana
may be used independently, because the name is that of one of the
wives of Alexander the Great, and appears under both spellings in
history. In the proof-sheets of the Synopsis of the Mollusca of
Great Britain, printed in 1819, the name appears on pp. 49 and 60
as Roxania, but in the MS. index, written by J. E. Gray, it is spelt
Roxana.
38 PROCKEDINGS OF tHE MALACOLOGICAL SOCIETY.
I might here note that Jangelia was invented by Leach and
accepted by Risso, and it is a pure coincidence that it should look
like a name intended to honour Mangili, with whom, as far as I have
been able to trace, it has absolutely no connexion. Through
inattention to this detail some of our most conscientious writers have
spelt it Mangilia.
Moricoprupa, gen. nov. for Purpura fenestrata, Blainville.
A certain peculiar shell has long been known as Liecnula (or
Sistrum) cancellata, Quoy & Gaimard. The generic name was
inapplicable, and I now find the specific one also doubly invalid,
being anticipated as well as preoccupied. Firstly, Drupa, Bolten, is
earlier than Zieinula or Sistrum, as well as Jeinella, all based on
the same group. The shell under consideration was obviously
not congeneric with the members of that genus. Lumped in,
however, was a series of smaller shells whose generic name appears
to be Morula, and it was likewise discordant with these. Shells more
like, also included, have been separated by Martens as Semiricinula.
I noted this name used subgenerically in the Wissensch. Ergeb,
Deutsch. Tiefsee Exped., Valdivia, 1903, vol. vii, pp. 95 and 1387,
without indication of novelty, so that it may have been previously
proposed, but the name does not appear in the Zoological Record so
far as I have seen. I therefore name muricina, Blainville, as
type, and for the shell named Purpura fenestrata, Blainville, 1832
= cancellata, Quoy & Gaimard, 1833, not of Bolten, 1798, I add
Muricodrupa.
In arriving at this result the following facts came to light. In
January, 1832, Duclos published a preliminary note (Ann. Sci. Nat.,
tom. xxv, pp. 90-5) on Purpuroid shells, following it up with a
further item in May (op. ert., tom. xxvi, pp. 103-12), “describing some
new species, and declaring his intention of monographing the
group with illustrations. ‘He quoted (p. 109) the publication of
Valenciennes’ species, P. speciosa, which he described as P. centri-
quadra. After June, but before August, Blainville published a
complete monograph, and therein named species figured by Quoy &
Gaimard in the Atlas tothe Voyage of the Astrolabe under vernacular
names, the text to the latter not appearing until 1833. The chronology
reads thus: Ante May, 1832, Valenciennes; May, 1832, Duclos;
post June, ante August, 1832, Blainville; 1833, Quoy & Gaimard.
The species concerned seem to be
Purpura canaliculata, Valenciennes, antedates P. canaliculata, Duclos.
chaidea, Duclos < P. nassoidea, Blainville
= P. nassoides, Quoy
& Gaimard.
speciosa, Valenciennes ¥s P. centriquadra, Duclos.
granulata, Duclos s P. tuberculata, Blain-
ville.
bicarinata, Blainville hi P. helena, Quoy &
Gaimard.
IREDALE : MOLLUSCAN NOMENCLATURAL PROBLEMS, 39
Purpura monodonta, Blainville, antedates LP. monodonta, Quoy &
Gaimard,
JSenestrata, Blainville ‘3 P. caneellata, Quoy &
Gaimard, not of Bol-
ten, Mus. Bolt., 1798,
p. 143.
However, P. chaidea, Duclos, is claimed to be identical with the
prior Purpura nodulifera, Menke, 1829. :
The species Duclos described as Purpura spheridia has been
recognized as Licinula morus, Lamarck, which name is later than
Morula papillosa, Schumacher, and which I determine as Drupa wva,
Bolten (Mus. Bolten, 1798, p. 56). In order to avoid change of the
well-known morus Pilsbry has recently pleaded that the figure given
by Chemnitz was not accurately determinable. The description,
however, is very good. He would then fall back upon the
illustration inthe Tabl. Encycl. Méthod., pl. 395, fig.6. Here again
danger lies, because that figure was named Licinula nodus by
Lamarck himself prior to his proposal of the name morus for the
same shell.
The outstanding groups appear to be as follows :—
Drupa, Bolten, 1798 (type, Durex ricinus, Linné) = Sistrum,
Montfort, 1810 = Rieinula, Lamarck, 1816 = Ricinella,
Schumacher, 1817.
Morula, Schumacher, 1817 (type, I. papillosa = Drupa uva, Bolten,
1798).
Semiricinula, Martens, 1903 (type, Purpura muricina, Blainville).
Muricodrupa, gen. nov. for Purpura fenestrata, Blainyille.
I had ranged the species in order when Dr. Cooke informed me
that he proposes to develop his studies on the radule in the near
future, and his notes show that in this group not only shell
distinctions coincide with radular differences, but also that
convergence in shell features may mask divergence in the characters
of the radula.
TERETIANAX, gen. noy. for Scalenostoma suterz, Oliver.
Bartsch in his ‘‘Monograph of West American Melanellid
Mollusks” (Proc. U.S. Nat.-Mus., vol. lili, Aug. 1917, pp. 295-356)
has in my opinion misused group names in an extraordinary manner.
One item will suffice: Melanella, Bowdich, is employed, two
subgenera being accepted, Delanella, s.str., and Baleis, Leach, 1852.
The former is characterized ‘‘ Melanellas with straight shells’’, the
latter ‘‘ Melanellas with flexed shells’’. The diagnosis of Jelanella
reads ‘“ Turreted; spire curved’’, and the type of Baleis is a straight
shell and is so included by Bartsch himself. In the Bull. U.S. Nat.
Mus. No. 90, Jan. 21, 1915, his colleague, Dr. Dall, gave a cursory
review of the group, writing the facts correctly.
On p. 354 Bartsch used Lambertia as of Souverbie, 1869, but that
name was invalid and had been corrected to Hypermastus by Pilsbry
in a paper quoted elsewhere in this essay by Bartsch. As a matter
40 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
of fact I note many group names missing which might have
significance in connexion with the new groups introduced by
Bartsch. He greatly confuses Subeulima and Scalenostoma, as may
be seen from the fact that he has described a Subewlima magnifica,
a shell 5mm. long, whereas the type was 23mm. long and not
congeneric.
I hope to deal thoroughly with this group later on, for I possess
species belonging to such rare sections as Selma, A. Adams, Apicalia,
A. Adams, and Hoplopteron, Fischer, the last named appearing to be
misunderstood by both Dall and Bartsch. In the meanwhile I
propose Zeretianax for the shell from the Kermadecs described by
Oliver under the name Scalenostoma sutert, a doubtful member of
this family (?).

PRESIDENTIAL ADDRESS.
By J. R. Le Brockton omin, M.A., F.E.S., etc.
Delivered 8th February, 1918.
A SYSTEMATIC LIST OF THE FOSSIL MARGINELLIDA.
In the List of recent Marginellide published last year I ventured to
hope that I might have time eventually to catalogue the fossil species
aswell. This necessary complement I am now able to bring forward,
arranged on precisely similar lines and with similar limitations.
It contains 850 names, but probably a number of omissions will be
detected from time to time, since I find the Zoological Record so
much less complete an index to fossil forms. In the case of papers
which appeared in serials the separate titles have frequently been
added in brackets when the paper is an important or comprehensive
one. The geological formation is quoted as given by the author in
his original description.
It only remains for me to express my thanks for renewed assistance
to the friends who helped me before, and to add the names of
C. D. Sherborn, A. Reynell, K. Martin, and M. Cossmann, to whom
I am equally indebted.

ON HELIX REVELATA, BRITT. AUCTT. (NON FERUSSAC, NEC
MICHAUD), AND THE VALIDITY OF BELLAMY’S NAME OF
HELIX SUBVIRESCENS IN LIEU OF IT FOR THE BRITISH
MOLLUSC.
By A. S. Kennan, F.G.S., and B. B. Woopwanrp, Bus:
Read 14th March, 1919.
ReGRerrabie as the supercession of a familiar and long-established ~
molluscan name is, it is unavoidable when that name proves to have
been based on an original misidentification. Such was the case
with Helix sericea, Drap., and H. rufescens, Penn., whilst now
H. revelata, Férussac (or Michaud) has similarly to be removed
from the British list, and the same fate awaits yet a few others to
be dealt with later.
he case concerning the specific name in question stands as
follows :—
Férussac in his Zableau de la famille des Limagons, 1821, January
edition, p. 48 (June edition, p. 44), under Helix, sub-gen. Helicella,
‘* 3e, groupe Les Hygromanes, Hygromanes,” cites: .
‘No. 273, REVELATA, nobis.
Habit. La France, les environs de Paris et d’ Angers.”
Neither figure nor description is given.
In 1831 Michaud in his Complément de Ul’ Histoire naturelle des
Mollusques. . . . de la France, de J. P. R. Draparnaud, describes
(pp. 27-28) and figures (pl. xv, f. 6-8) what he considered to be
Férussac’s shell, giving as additional locality “ Les valons des
Alpes”, and adding ‘‘ Elle est rare”.
Gray, and after him Brown, Forbes & Hanley, and Reeve,
determined the British shell as being identical with Férussac’s,
euided thereto obviously ‘by Michaud’s description and figures.
Jeffreys, however, considered Férussac’s species to be probably
identical with his ‘‘.H. sericea, Miiller”, 1.¢. H. granulata, Alder
(Brit. Conch., i, pp. 202-204), which we now know is not represented
on the Continent. He therefore described the English shell as
IL. revelata, Michaud, and in this he has been followed by ‘Taylor
(Monograph [iii], p. 36).
Michaud’s brief description applies in many respects to our form
which has so long passed under the name he adopted, but his species,
while tallying in size with ours, has a whorl more (5 instead of 4)
and is higher in the spire as the measurements and figures given
show. Moreover, the localities cited are not among those in which
our shell occurs. Michaud’s species is, therefore, not identical with
the British form, which has been misidentified with it. Anyhow,
the name rerelata cannot stand because the shell it was proposed for
is unknown, and Michaud’s adoption of it does not make it valid.
Bouchard-Chantereux next, in 1837 (Mém. Soc. Agric. Boulogne,
sér. m1, tom. i, p. 180), quoted the species, as of Férussac and
Michaud, in his *‘ Catalogue des Mollusques . . . observés . . . dans
134 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY,
le département du Pas-de-Calais”. The British mollusc is a stranger
to this locality also, and Bouchard’s shells were probably, as
suggested by Moquin-Tandon (Hist. Mat. Moll. France, ii, p. 212)
and subsequently by Jeffreys (Brit. Conch., i, p. 204), referable to
ET, fusea.
To H. fusca, also, may be referred the examples figured by Captain
T. Brown in the first edition (1827) of his Jdlustrations of the
Conchology of Great Britain and Ireland (pl. xl, f. 3-5) under the
name of Vtrina membranacea, but which in the second edition
(1837-44) and the subsequent Illustrations of the Land and Fresh
Water Conchology of Great Britain and Ireland he described as
HT. revelata.
In October, 1839, J. C. Bellamy found near Mevagissy, Cornwall,
a helix new to him for which he proposed the trivial name of
subvirescens (Bellamy’s Nat. Hist. South Devon, p. 420, fig. ‘ Tab.
XVII?)
In is same year (and according to Couch a little later) Edward
Forbes brought to Dr. Gray specimens from near Doyle’s monument,
Guernsey, which they identified, probably as already remarked,
through Michaud’s description and figures, with ZH. revelata,
Férussae (Turton’s I/anual, new ed. by J. KE. Gray, 1840, pp. 53,
152-153).
Bellamy exhibited his shell to the meeting of the British
Association at Plymouth in 1841, but its name does not appear in
the ‘“ Report’’.. However, Couch in his Cornish Fauna (Pt. ii,
p. 47) under Helix revelata remarks: ‘‘ Mr. Bellamy discovered this
species near Mevagissy, and it has been since found by Mr. Forbes in
Guernsey. Mr. Bellamy’s original specimen was examined by the
eminent naturalists present at the meeting ... and especially
by Mr. Gray.”
From the foregoing it becomes apparent that our British shell has
been misidentified with the Z7. revelata of Férussac and of Michaud,
and should bear the name bestowed on it by Bellamy of H. sub-
virescens.
Mention may appropriately be made here of certain Continental
forms closely allied to the one in question which have sometimes
been associated with it in synonymy.
In 1845 Morelet (Deseript. Moll. Portugal, p. 65, pl. vi, f. 4)
described and figured under the name of HZ. ponentina? a somewhat
larger form, obscurely bifasciate, having a reflexed lip furnished
with an internal white riblet. Récluz, reviewing Morelet’s work
the same year in the Revue Zoologique (p. 311), changed the
name to oceidentalis on the ground that ponentina was an improperly
formed word.
The following year, Pfeiffer founded on a specimen in the Cuming
1 Gray’s reference in synonymy (Turton’s Manwal, new ed., 1857, p. 139) to
‘“* Helix subviridis, Bellamy, Brit. Assoc., 1841, South Devon’’ is
consequently a delightful and characteristic Grayism.
2 From the Portuguese ponente or poente, meaning ‘‘ west’’.
KENNARD & WOODWARD: ON HELIX REVELATA, BRITT. AvCTT. 158
collection his H. lisbonensis (Symb. Hist. Helic., iii, 1846, p. 68), but
subsequently (Mon. Helic., 1, 1848, p. 131) acknowledged it to be
a synonym of Morelet’s species which he accepted under Récluz’s
amended name of occidentalis. Under H. revelata, Fér., Pfeiffer
(Mon. Helic., i, p. 65) placed Michaud’s shell as well as the British
revelata of Gray, adding HZ. badiella, Ziegl. In a later volume he
further included Brown’s record, thus showing that he had not
carefully discriminated the several forms. \
Dupuy (Mist. Nat. Moll. France, p. 189, 1848, pl. viii, f. 9) adopts
Morelet’s species and, overlooking the fact that both were described
as having five whorls, considers (p. 191) Michaud’s revelata to be
the young form with incomplete peristome. He adds in a note
(p. 192) Michaud’s description in full followed by that of Gray for
the British shell, which he evidently, with a certain amount of
doubt, thought might be the same.
Moquin-Tandon (/iist. Nat. Moll. France, ui, p. 221, 1856, pl. xvii,
f. 10-13) cites Morelet’s species under Récluz’ name of occidentalis,
and considers the revelata of Michaud, but not that of Férussac or of
Bouchard-Chantereaux, to be asynonym. He takes no note of the
British shell. :
Bourguignat’s Helix ptilota (Malac. Bretagne, 1860, p. 55, pl. i,
f. 5-8), save for its black apex, agrees closely with the British form,
of which it is in all probability only a local variation.
Servain in 1880 (tudes Moll. Espagne § Port.) added (p. 54)
HT, salmurina and (p. 56) the new var. martigenopsis of revelata, while
Locard in 1882 (Prod. Malac. Frang., i, pp. 316-317) published
Bourguignat’s manuscript names, //. venetorum and H. villula.
Silva e Castro in 1887 (Jorn. Acad. R, Ser. Lisbon, xi, pp. 232-237)
increased the number of the group by five: ZZ. nevesiana, FH.
conimbricensis, H. platylasia, Bourg. MS., H. rosaz, and H. aporina.
These were summarized and //. atachypora, Bourg. MS., added by
Locard in his “ Conchyliologie Portugaise” (Areh. Mus. Lyon, vii,
mém. 1, 1899). No grouping is, however, attempted in these papers.
Westerlund (Fauna Paléarct. Region Binnenconch., Helix, p. 61,
1889) seems to have placed most of these forms together under
revelata, Fér., while at the same time he detected and named Z.
montivaga out of a gathering of H. ponentina sent him by Morelet.
Pilsbry (Mlanual, ser. 11, vol. ix, p. 274, 1895) recognizes the
revelata of Férussac, including the British shell, with ponentina,
Dup., and martigena, Fér. (which is a nomen nudum), as synonyms,
and associates with it conimbricensis, Silv., venetorum, Bet., nevesiana,
Silv., vdlula, Bgt., platylasia, Bet., whilst as a variety he places
occidentalis, Récluz, with its synonym Jisbonensis, Pfr. Bourguignat’s
H. ptylota [sic] he treats as a distinct species. The other named
forms appear to have been passed over by him.
Germain (J/oll. France, ii, 1918, p. 128) also accepts Férussac’s
HT, revelata, with H. venetorum, Bgt., and H. villula, Bet., as synonyms.
He regards (p. 129) H. ptilota, Bet., as a separate species, and makes
no allusion to Morelet’s shell, nor to the British form.
In the absence of authenticated specimens and adequate descriptions
136 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
it is impossible to allocate all these various forms to their proper
relative positions, nor are we at all certain at present to which
helicoid genus they rightly belong ; but so far as concerns those with
which we are more immediately dealing just now, the following
general arrangement may be hazarded :—
A. Sharp-lipped Group: without internal riblet.
H. revelata, Fér., of Michaud: a rare Alpine form for which,
when rediscovered, a name will be wanted, the present one
being invalid, Férussac’s species being indeterminate.
H. subvirescens, Bellamy, for the British shell.
Syn. HZ. ptilota, Bourgt., and possibly a few others.
B. Everted, white-lipped group, with internal, white riblet.
IT. montivaga, Westerlund.
Syn. H. salmurina, Serv.
HT. ponentina, Morel. (= occidentalis, Récluz).
Syn. H. lisbonensis, Pfr., and probably the majority of the named
continental forms.
ON THE GENERIC NAMES FOR THE TWO BRITISH ELLOBIIDA
[OLIM AURICULIDA], MYOSOTIS, DRAPARNAUD (= DENTI-
CULATUS, MONTAGU) AND BIDENTATA, MONTAGU.
By A. 8. Kennarp, F.G.S8., and B. B. Woopwarp, F.L.S.
Read 18th June, 1919.
THeEse two species of mollusca are to-day considered to represent
genera quite distinct from any of the following, to one or other of
which they have in the past been referred, viz.: Carychium,
Miller, 1774 (altered to Cartechium by Férussac in 1807), Pythia,
Bolten, 1798, Hllobium, Bolten, 1798 (= Auricula, Lamarck, 1799),
Volvaria, Lamarck, 1801, Acteon and I/elampus, Montfort, 1810, and
Conovula, Schweigger, 1820 (= Conovulus, auctt., founded on
Lamarck’s ‘‘ Conovule ?” of 1812).
Incidentally their history begins with that of a shell which does
not belong to their group, but which at first was confounded with
them, A small Voluta was depicted in Boys & Walker’s Zestacea
minuta rarvora [1784], fig. 61; this was copied in Kanmacher’s edition
of Adams’ Essays on the Microscope, 1798, pl. xiv, fig. 27, and on
p- 639 of the text given Jacob’s name of Voluta alba. It was adopted
under that name by Turton in his edition of 4 General System of
Nature, by Linneeus, vol. iv, 1802, p. 361, and again by Montagu in
his Zestacea Britannica, 1808, p. 235. Montagu reverts to this shell
in his Supplement, 1808, p. 101, & propos of a very similar specimen
which he describes, and suggests that the original example sent by
Boys may have been a young Bulla obtusa | = Retusa alba olim,
Tornatina obtusa (Mont.)']. From his description of the second
specimen, Forbes & Hanley were led to infer, Hist. Brit. Moll.,
' Proc. Malac. Soc. Lond., xi, pp. 300-301.
KENNARD & WOODWARD : GENERIC NAMES FOR BRITISH ELLOBIDH. 187
vol. iv, p. 192, that this was “ probably a minute foreign Mlarginella”’.
It was in his Supplement, too, p. 100, pl. xxx, fig. 2, that Montagu
established the Voluta bidentata, which is one of the two species
under present discussion.
According to Moquin-Tandon, Jurine (Helvetischer Almanach, 1817,
p. 84) included under the name Auricedla, an A. myosotis and
A. lineata. he authors of the species are not given by Moquin-
'andon, but if, as seems to be inferred from his citations, they were
Draparnaud’s species, the association of two such diverse animals
without indication of a type renders the name useless, and it may be
safely disregarded, even though Moquin-T'andon adopts it as a
sectional name for the latter of the two.
In 1819 Turton, in his Conchological Dictionary (p. 250), quite
oblivious of his Voluta alba in the General System of Nature cited
above, described under the same name a shell manifestly identical
with Montagu’s V. bidentata.
Leach, the same year, in the proofs of his Molluscorwn Britannie
Synopsis, proposes Jaminia (p. 184) for bidentata and Aleata (p. 185)
for denticulata. The Voluta alba does not seem to have received his
attention.
Gray in 1821 (London Medical Repository, xv, p. 281) used Phytra
(probably a misspelling for Pythia which he adopts in 1847) for
V. denticulata ; whilst in 1825 (Annals of Philosophy, xxv, p. 415) he
refers bidentata and alba, both of Montagu, to Aurieula.
Brown in 1827 (Zilustrations of the Conchology of Great Britain and
Treland, 1st ed., p. iv) used Leach’s name Jaminia (which he wrong-
fully attributed to Bruguiére, who never employed it) for a group in
which the molluscs in question were included.
Fleming in 1828 (History of British Animals, p. 333) referred
‘¢ V. alba, Mont., Test. Brit., 235. Turton’s Conch. Dict. 250”
(thus mixing two distinct forms) to Lamarck’s Volvaria, whilst
putting under Acteon the denticulatus and bidentatus of Montagu.
Jeffreys followed Fleming as to alba in 1830 (Zrans. Linn. Soe.
Lond., xvi, p. 869), but put a ‘“?” to the reference to Montagu
and placed the species under ‘‘Aurieuwla, Drap.”’
Bivona Bernardi in 1882 (Hffemeridi scientifiche e letteraire per la
Sicilia, i, p. 58) founded the genus Ovatella for O. punctata (which is
akin to our denticulata) and another species belonging to quite another
type of shell; whilst a little later (op. cit., ii, p. 18) he adds an
O. bidentata, which is distinct from the British species of that name
and which was renamed dzvone by Philippi (Znumeratio Molluscorum
Sicilie, 11, 1844, p. 118). We have been indebted, and hereby
return our grateful thanks, to the Marchese di Monterosato for the
opportunity of examining these species of Bivona with other
Mediterranean forms.
In 1840 Gray (Turton’s Manual, new edition, pp. 224-228) put
the three species under Conovulus, which he divided into Ovatella
(Bivona) for C. denticulatus and a new section Leuconia for
C. bidentatus and albus.
This he changed in 1847 (Proc. Zool. Soe. Lond., xv, p. 179).
138 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
‘¢ Alexia, Leach MSS., 1819,’’ was there proposed for Vol. denticulata,
Phytia, respelt Pythia, and ‘‘ Jaminia, Brown, not Risso”’, ranking
as synonyms; whilst for the following genus he gave :—
‘* Teuconia, Gray, 1840. Volvaria, sp., Flem. Voluta alba.
Jaminea [sie], Leach MSS. Vol. bidentata.
Ovatilla | sic], sp. Bivon, 1832. Ovat. bidentata.”
Forbes & Hanley (Hist. Brit. dJMoll., iv, 1852, pp. 190-197)
referred these molluscs to Conovulus, making alba of the Conch.
Dict. a synonym of didentatus, and ignoring Gray’s sectional names.
Moquin-Tandon in 1856 (Hist. nat. Moll. France, ii, pp. 415-20)
included these shells under Carychium, putting denticulatum in the
section Ovatella (which he misquotes as Conulus, sect. Ovatella,
Gray) and $didentata, which he misidentified with myosotis of
Draparnaud, under the section Phytia of Gray. He took no note
of alba.
In 1857 (‘Turton’s Manual, new edition, pp. 192-196) Gray reverted
to his arrangement of 1840, making alba, however, a variety of
bidentatus and restricting it to that of Turton’s Conch. Dict.
Gwyn Jeffreys (Brit. Conch., v, 1869, pp. 103-109) elected to put
these snails under the genus MJelampus of Montfort, making alba of
the Conch. Dict. a variety of bidentatus.
Of the most recent writers of the group, the Marchese di
Monterosato (Wat. Srecl., xviii, 1906, pp. 125-130) has adopted Alexia
of Leach for denticulatus, Mont., put myosotis, Drap., ina new genus
Myosotella, and bidentatus, Mont., under Leuconia of Gray.
Such being the literary history of the question, it remains to
determine the available generic names for the two forms. It is
a pity that Leach’s original manuscript names of Jaminia and
Alexia cannot be revived. Unfortunately the former was used by
Risso through an error of misinterpretation in 1826 (//ist. Europ.
merid., iv, p. 88) for certain of the Pupillide before Brown in 1827
revived it for a mixed group that included the present shells.
Bivona’s Ovatella appears conchologically more closely allied to the
myosotis section and so not available. Hence recourse must be had
to Gray’s name Leuconia. For the other section Leach’s original
Alexia was only made valid by Gray’s publication of it in 1847, by
which time it had been anticipated by Stephens, who in 1886
employed it fora genus of Coleoptera, so that, as pointed out by one
of us in 1908, Gray’s Phytia is the only choice.
The essential synonymy is, therefore, as follows :—

originally they were narrowly rounded and of the same width as, or
even a little narrower than, the intervening spaces; the ribs are
straight, and as a rule alternately longer and shorter, but towards
the anterior end of the specimen there are irregularities in this
respect. Asarule each longer rib commences at the suture of the
shell and, increasing in strength as it passes across the inner area of
the whorl, is raised into a more or less prominent compressed
tubercle on the umbilical margin, whence the rib passes straight
across the broadly-rounded whorls without any indications of |
tubercles. In one instance one of the longer ribs bifurcates at the
tubercle on the umbilical margin, the two divisions being continued
thence across the whorl. ‘The earliest part—about the first third—
of the outer whorl is very imperfect, nearly one-half of the whorl
being broken away, but even here, so far as one can see, there are no
traces of a row of tubercles on each margin of the periphery.
The imperfection of the earliest portion of the outer whorl is not
clearly shown in Mantell’s figure, which, therefore, causes the shell
to appear to expand much more rapidly than it actually does.
Unfortunately the [septal] sutures are not visible.
Respecting the pit at Offham, where the specimen was found,
Mantell writes (op. cit., p. 100): ‘‘ This excavation lies on the road-
side, between Offham and Cooksbridge; it produces ammonites,
nautili, turrilites, scaphites, ete.”
The road from Offham (12 miles north-west of Lewes in Sussex) to
Cooksbridge, about a mile distant, passes almost due north from
Offham, and, according to the map of the Geological Survey, the
portion of the Chalk traversed by it is referred to the Lower Chalk
only.’ In neither of the two volumes of the Memoirs of the
Geological Survey on the Cretaceous Rocks of Britain, dealing with
the Lower and Middle Chalk (vol. 11, 1908) and with the Upper
Chalk (vol. i111, 1904) respectively, is there any reference to a
chalk-pit on the roadside; but in the volume devoted to the Upper
Chalk mention is made of the large quarries south of Offham; these
are stated (vol. ii, p. 46) to ‘‘exhibit a fine section through the
zones of Micraster cortestudinarium and FHolaster planus into the
Terebratulina zone’’, and a measured section of the quarries is given.
It is also recorded in the same work (p. 47) that ‘‘The highest part
of the zone of Jl. cortestudinarium appears to be exposed in the
upper pit on Offham Hill now disused’’, There is no record of any
pit to the north of Offham.
In 1827 J. de C. Sowerby? figured an example which he referred
to Mantell’s species, and characterized the species as follows:
‘‘Umbilicated, costated; costae Jarge, numerous, annular, simple;
whorls ventricose, very few; the inner ones half exposed; aperture
transversely oblong.”
1 The Survey include in the Lower Chalk the zone of Schlenbachia varians
and the zone of Holaster swbglobosus (having at its top the marls with
Actinocamazx plenus, that are regarded as constituting a subzone).

156 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
To this description he adds the following remarks :—
‘About three whorls, rapidly increasing, compose this Ammonite:
all the cost reach the edge of the umbilicus, half or more of them
turn into it, and at the same time are rather enlarged; the cost
and the spaces between them are nearly equal.
‘‘From the lower chalk at Guildford: presented to Mrs. Murchison
by Mr. Mantell. It is only half the size of the one figured in the
Geology of Sussex, where it is spoken of as a very rare shell.”
It is unfortunate that the precise locality of Sowerby’s figured
specimen is not recorded, since several zones of the Chalk are
represented in the neighbourhood of Guildford. Thus, according to
the Memoirs of the Geological Survey on the Cretaceous Rocks of
Britain (vol. ii, Lower and Middle Chalk of England, p. 55), a
quarry 14 miles south-east of Guildford exposes Lower Chalk with
the Belemnite Marls, whilst in quarries to the west of Guildford the
Melbourn Rock (zone of Rhynchonella cuviert) is exposed (vol. 11,
Lower and Middle Chalk of England, p. 386). The upper part of
the Terebratulina zone is seen in the Shalford quarries south of
Guildford (vol. i1, Lower and Middle Chalk of England, p. 387), and
an old disused quarry, about a mile to the south-east of Guildford,
presenting a perpendicular face of about 100 feet, exhibits the
succession of the chalk from, and including, the upper part of the
Terebratulina zone (vol. 11, Lower and Middle Chalk of England,
p. 387) ‘‘through the zone of Holaster planus to the Upper Chalk”
(vol. iii, the Upper Chalk of England, p. 175). At Monkshatch,
about 5 miles west of Guildford, there is a large disused quarry
showing about 42 feet of the Holaster planus zone resting upon about
30. feet of the Zerebratulina zone (vol. iii, the Upper Chalk of
England, p. 176), whilst Dr. Barrois thought he recognized the
Marsupite zone on the north side of the Hog’s Back, near Guildford,
in 1876 (Recherches sur le Terrain Crétacé supérieur, 1876, p. 189).
In the absence, therefore, of precise information as to the pit from
which the fossil was obtained, it is not possible to say from what
horizon Sowerby’s figured specimen came. Further, the present
location of this fossil is unknown to the writer, so that an actual
comparison with Mantell’s type-specimen is not possible.
We think, however, that there is great reason for believing Pictet'
to be right in considering this specimen as specifically distinct from
Mantell’s type-specimen. He considered it to be without doubt the
adult of a slightly compressed form of Brongniart’s Ammonites
gentonr.*
In his Description of the Fossil Remains of Mollusca found in the
Chalk of England (Mon. Pal. Soc.), Sharpe figured four specimens
(pl. xviii, figs. 1, 2, 3, and 5, and the suture-line fig. 8) as Ammonites
navicularis. These are now in the British Museum collection. His
largest example [B.M. No. 36834], the original of his fig. 1, has

the following dimensions: diameter of shell, 117mm. (1); height
of outer whorl, 50mm. (0°43); thickness of outer whorl, about
58mm. (0°49); width of umbilicus, 35mm. (0°30). The fossil is
fairly well represented (but reversed) of the natural size in his
fig. 1. The ribs are alternately longer and shorter; the longer
commence at the suture of the shell, cross the inner or umbilical
area of the whorl, and increasing in strength form a tubercle at the
edge of the umbilicus, and sometimes bear a second tubercle on each
side of the whorl at about one-third of the width of the lateral area
from this umbilical margin; the shorter ribs rise on the side of the
whorl, nearer the umbilicus than the periphery; all the ribs cross
the periphery, but are slightly angular or feebly tuberculated at each
margin of the periphery, even at the anterior end of the specimen,
de. at adiameter of 117mm. Between the two tubercles near the
umbilical margin the longer ribs are straight and have an almost
radial direction or are but feebly reclined, but between the second
row of tubercles and the row at the margin of the periphery, both
the longer ribs and the intervening shorter ribs have a slight
forwardly concave curve, and at a point rather nearer the tubercle
at the margin of the periphery than the tubercle in the second row
from the umbilicus each rib is angular and feebly raised, and in the
earliest part of the outer whorl bears a small but distinct tubercle ;
all the ribs are straight on the periphery. ‘The ribs are prominent,
rounded, and at the commencement of the outer whorl not quite so
wide as the interspaces, whilst near the anterior end of the specimen
they are only one-half the width of the interspaces. Thus there are
differences between this fossil and Mantell’s type-specimen, differences
which we think must be regarded as of specific value.
_ The specimen has been labelled ‘‘ Grey Chalk: Dover’’. According
to the Museum register, the fossil was obtained from Mr. Mackie,
but both the horizon and locality of the fossil are unrecorded. Upon
the. specimen is written in ink (apparently in the handwriting of
Daniel Sharpe), ‘‘ Fig. 1, Pl. 18. Mr. Mackie.”” Although Sharpe’s
figure is reversed and a little restored, there can be no doubt about
its being the figured example. Sharpe does not specially refer to
the fossil in the text of his work, but in the explanation of the plate
he states that the specimen is ‘‘ from the Grey Chalk of White Nore,
Dorsetshire”’ and that it is ‘‘in the collection of KE. H. Bunbury, Esq.”
He cites the species as being ‘‘common in the Lower Chalk of the
South of England”’.
In the explanation of his figures Sharpe states that the original of
fig. 2 came “from the Grey Chalk near Lewes”’, and that it was
‘‘in the collection of Henry Catt [afterwards Willett |, Esq.’ This
collection is now in the Brighton Museum, and in the Catalogue of
Types and Figured Specimens in that Museum, published in the
Museum Report for the years 1891-2, a specimen in the Willett
collection is recorded (p. 16) as the original of Sharpe’s figure.
Although this specimen, for the loan of which we are indebted to
the Chairman and Committee of the Brighton Museum, has been
labelled as haying been described and figured by Sharpe in “ Pal.
158 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY.
Soc., 1856, p. 39, pl. xviii, fig. 2’, it is to be observed that it bears
an old and very much faded label stating that it came ‘‘ From the
edge of the Chalk [?strata] Sutton Veny .. .” Now Sutton Veny
or Veney is in Wiltshire, about three miles south-east of Warminster,
whilst Sharpe states that the original came ‘‘ from the Grey Chalk
near Lewes”. Further, the fossil is not only larger than Sharpe’s
figure, its greatest diameter being 78°5 mm., but compared with that
figure the specimen is somewhat distorted and less inflated, the cross-
section of the whorls is less quadrate and relatively narrower, and on
each side the limits of the umbilicus are obscured by matrix ; whilst
the tubercle on each margin of the peripheral area is more obscure.
It seems, therefore, very doubtful if this is actually the example
figured by Sharpe. More especially so, since there is in the British
Museum collection [ register number C. 5027 | a fossil from the Chalk-
marl of Lewes in Sussex, that has been labelled as the original of
Sharpe’s fig. 2, and that agrees in form and dimensions with
Sharpe’s figure. It is marked in ink (in what is believed to be
D. Sharpe’s handwriting, and in the same manner as several other
figured specimens), ‘‘Fig. 2, Pl. 18. The fossil shows the
dimensions of the umbilicus on each side, but the imperfection of
the earliest part of the outer whorl is not indicated in Sharpe’s
figure. Still, the specimen agrees so well with the figure on the
whole that there appears to be every reason for regarding it as the
figured example, rather than the fossil in the Brighton Museum.
It has the following dimensions :—Diameter of shell, 59mm. (1);
height of outer whorl, 25-5 mm. (0°46); thickness of outer whorl,
35mm. (0°59); width of umbilicus, 16mm. (0°27); and width of
periphery between marginal tubercles, 15 mm. (0°25). It agrees
very well with the earlier whorls of the original of Sharpe's fig. 1,
but is, if anything, a little more inflated. It shows, however, the
same slight curvature of the ribs on the lateral area. The principal
ribs commence at the suture of the shell; each bears a tubercle at
the umbilical margin, and a second at a short distance therefrom on
the lateral area; each is ornamented with a small tubercle at each
margin of the periphery, and at about half-way between the row
of tubercles at the margin of the periphery and the second (counting
from the umbilicus) tubercle on the lateral area each rib is raised
into a feeble angular prominence. The tubercles at the margin of
the periphery are quite distinct at the anterior end of the specimen.
The suture-line is not shown. Although a little more inflated than
the original of Sharpe’s fig. 1, this example seems to be specifically
identical therewith.
he specimen depicted in Sharpe’s fig. 3? is a more compressed
shell than the original of his fig. 1. It now forms part of the
British Museum collection [register number 50287]; it has the
following dimensions, fully one-third of the outer whorl being
1 The compression of the shell is represented in fig. 3a, but is not so well
indicated in fig. 30.
CRICK: ON AMMONITES NAVICULARIS, MANTELL. 159
occupied by the body-chamber :—Diameter of shell, 66mm. (1);
height of outer whorl, 29mm. (0°44); thickness of outer whorl,
32mm. (0°48); width of umbilicus, 18 mm. (0°27). The ribs are as
a rule alternately longer and shorter, but there is some irregularity
in this respect, there being sometimes two smaller ones interpolated
between a pair of longer ribs; the ribs have a nearly radial direction,
they are straight up to a point about two-thirds of the width of the
lateral area from the umbilical margin, where they bend feebly
forward as far asthe margin of the periphery, and then pass
straight across the latter. In passing up the inner area of the
whorl each longer rib gradually increases in strength up to the
umbilical margin, where it is raised into a distinct elongated
compressed tubercle ; each of these ribs, therefore, lacks the distinct
bituberculate character of the longer ribs on the originals of Sharpe’s
figs. 1 and 2. Up to a diameter of about 57 mm. each rib is slightly
angular at the margin of the periphery, but cannot be described us
tuberculated ; beyond this diameter the angularity gradually dis-
appears. At a point nearly in the middle of the lateral area, but
a little nearer the periphery than the umbilical margin, each rib is
also slightly angular up to about the same diameter, “the angularity
being more distinct and elevated, and even amounting almost to
a tubercle, on the younger portion of the outer whorl. The inner
whorls are not displayed.
The specimen is from the Lower Chalk of Chardstock, Somerset,
and was formerly in the collection of Professor John Morris. It is
marked in ink (apparently in the handwriting of Daniel Sharpe).
‘‘Chardstock, J. Morris, P]..18, Figs. 8a and "5, and there can be
no doubt whatever about its being the figured specimen.
The original of Sharpe’s fig. 5a has the following dimensions :—
Diameter of shell, 40 mm. (1); height of outer whorl, 17 mm. (0°42) ;
thickness of outer whorl, 21mm. (0°52); and width of umbilicus,
12mm. (0°30). It is an entirely septate specimen with thirty-one
ribs in the outer whorl. Asa rule the ribs are alternately longer and
shorter; the longer arise from the suture of the shell and increasing
in strength as they cross the inner area (or umbilical wall) of the
whorl are raised at the umbilical margin into a prominent compressed
tubercle, thence each rib has an pinost radial direction as far as the
middle of the lateral area, where each rib is raised into a transversely
compressed tubercle, the rib then turning slightly forward and
crossing the periphery in a feeble forwardly-convex curve. Near
the commencement of the outer whorl, ¢.e. where the shell has
a diameter of about 17mm, the row of tubercles on each margin
of the periphery and the median row of tuber¢les gradually disappear,
as shown in Sharpe’s fig. 56, but better still in the view of the inner
whorls represented in his fig..5¢. Beyond this point there is on
either margin of the periphery only a very feeble angularity, which
soon disappears. Unfortunately the inner whorls of the original
of his fig.°3 are not shown, but so far as can be seen the original of
his fig. 5 closely resembles that specimen, but differs in having
slightly more inflated whorls, a little coarser ornamentation, with

a few of the larger ribs more prominent than the rest and provided
with relatively larger tubercles at the middle of the lateral area.
This specimen is also from the Lower Chalk of Chardstock,
Somerset, and formerly belonged to the collection of Professor John
Morris. To it is attached a small white label marked in ink (in
apparently the handwriting of Daniel Sharpe), ‘‘Pl. 18, Fig. 5.”
Although reversed and a little restored, Sharpe’s figure has un-
doubtedly been taken from this fossil.
Whether Sharpe’s specimens are correctly referred to Mantell’s
species, and also whether they are belong to one and the same species,
there is some reason to doubt. Probably the originals of his figs. 1
and 2 are specifically identical, whilst the original of his fig. 5 may
be the inner whorls of a somewhat more spiny and rather more
coarsely-ornamented example of the form represented in his fig. 3.
ON A SANDSTONE CAST OF ATURIA ATURI (BASTEROT), FROM
THE MIOCENE OF WESTERN AUSTRALIA.

PLATES V AND VI.
Own account of its wide geographical distribution and its restriction to
Miocene seas, Aturia aturi ranks as one of the most interesting
Cephalopods of Tertiary times.
The specimen forming the subject of this notice was collected
some years ago by Mr. Harry W. Field in the vicinity of Albany,
Western Australia, during a prospecting survey for coal. It was
found as a natural cast in a sandstone deposit, accompanied by some
other fossils, similarly preserved and determinable, as Lostellaria,
Glycymeris cf. laticostatus (Quoy & Gaimard), and a Pecten, besides
Kchinoid remains which Dr. F. A. Bather recognizes as belonging to
either Linthia or Schizaster.

The fossil consists of a natural cast in a yellowish sandstone
of a completely involute shell, thus resembling the Mautelus of
modern seas.
It exhibits the contour of an almost complete body-whorl with an
imperfect septal region, which on one side shows some effects of
crushing during the process of fossilization. It belonged to a shell
that was discoid, flattened, narrowly rounded at the periphery, and
possessed an aperture of greater height than width. The marginal
sides of the aperture just above the central region have a slightly
elevated curvature beneath a shallow area of excavation containing
the umbilical centre. The body-chamber is extensive, its height
being about one-third in excess of the width measurement, while the
central lateral region is depressed until the deeply sloping curvature
is reached, which leads to the rounded peripheral margin.
The septal region is so imperfect that only one or two septa
immediately contiguous to the body-chamber are preserved, although
they possess the strongly curved sutures, characteristic of the genus
Aturia, while one of the angular lateral lobes is distinctly marked
162 PROCEEDINGS OF THR MALACOLOGICAL SOCIETY.
by an inverted V-shaped line directed obliquely outwards to the
shell-wall. It is unfortunate that through bad preservation there is
no evidence of the large invaginated siphuncle. The testiferous
structure which once covered the cast must have been extremely
thin, as the finely semicircular surface striations are very distinct,
being closely arranged, regular, and parallel with the rounded
margin of the aperture; certain growth periods appear to be also
represented by a few more or less obscure, distant, and strongly
curved ridges. There is besides what is supposed to be an impression
of the annular band, which would indicate the position of the shell-
muscle by which the animal was attached. It is represented by two
parallel, nearly contiguous, curved lines, which bend over to the
umbilical centre in front, and in the other direction pursues an
obliquely downward course to the periphery, differing from the true
Nautilus, which shows a similar marking but of greater elevation and
more ovally arched. Some distance below, another line can be
traced which is more or less parallel with the upper curvature
marking, while the space between would represent the area of
attachment of the shell-muscle. Still further down, there appear
to be traces of the septal band, which takes a sinuous course across
the body-chamber.
According to the terminology adopted by Mr. L. E. Griffin’ in
connexion with muscle-markings on the inner surface of the body-
chamber of the recent Nautilus, it is stated that there are three
‘aponeurotic bands’”’ extending from the deeply arched attachment
area of the shell-muscle, viz. one dorsal connecting with the surface
of the central chambered region, and two ventral, the upper of which
is known as the ‘‘ anterior ventral aponeurotic band”’, while a distant
lower one is named the ‘‘ posterior ventral aponeurotic band’’, both
being directed across from the umbilical wall to the inner surface of
the peripheral region. It would seem, therefore, that the terms
‘annular’? and “ septal ” bands formerly i in use for specifying these
megs markings should now be superseded by regarding them as
‘“aponeurotic”” bands, which refers to the membrane surrounding
the muscular organs.
Our lately deceased member, Mr. G. C. Crick,’ carried out some
valuable researches on the muscle-markings observed in_ the
Ammonoid group of the Cephalopoda, which have been of wide
interest. The reference on the present occasion to corresponding
markings in the genus Aturta appears to be made for the first time.
The less complete lateral aspect of this fossil discloses a large
cavity near the peripheral margin of the upper part of the body-
chamber and well below its surface, containing what appears to
resemble a depressed sub-oval Ostreiform valve with evidence of

concentrically laminate structure. On account of its shape and
position, there is also the suggestion that this supposed valve may
be the remnants of the hood of the Cephalopod, which, according
to Owen’ with regard to Nautilus, is a ‘ ligamento- museulan Ane
that surmounts the head”. ‘This Nautiloid was long considered to
belong to Afuria stczac (Sowerby) of Eocene times s, although, as
pointed out by Dr. Ioord and other paleontologists, the two species
are quite distinct, Aturia aturt being a much more compressed shell
and possessing a more elongate aperture.

Hisrory AND SrrarigRAPHY OF THE SPECIES.
Messrs. Jutson and Simpson may claim to have first recorded this
fossil from Western Australia, and determined it as Aturia australis
in 1915. They obtained it from the north-east of Albany, where
probably Mr. Field’s specimen was found, in ‘‘ marine beds forming
alow plateau”’ which they termed the ‘“‘ Plantagenet Beds”; it was
associated with Mollusca, Bryozoa, Echinoids, and an abundance
of siliceous Sponges.? No figure or description ‘was given of their
specimen, although the authors mentioned that the species was
known in the ‘lertiaries of Victoria, where it extended from the
Oligocene to the Pliocene formations. ‘This is probably the ae
reliable determination of a Tertiary mollusc from Western Australi:
their usually imperfect preserv ation having hitherto malitated
against the compilation of accurate specific lists from which to obtain
a knowledge of fannistic assemblages, a fact which has been
remarked upon by Mr. 1. Glauert* as late as 1910. In this way
they form a striking contrast to fossils found in the Victorian and
South Australian Yertiaries, which are of prolific occurrence and
usually in a fine state of preservation. The presence of this
organism in Australian rocks was, however, first indicated by J. E.
‘'enison- Woods, whose brief description of the same was accompanied
by an excellent text-figure of a cast showing the septal region, but
with no body-whorl. It was referred to as the most predominant
fossil of the Mount Gambier beds of South Australia, although its
determination was mistaken for Mautilus siezac of J. Sowerby,

Australia, described by Dr. Hinde (Bull. Geol. Surv. W. Australia,
1910, No. 36, pp. 7-21, pls. i-iii), which Mr. Chapman considers, ‘in
some respects,’’ to resemble the spicule-bearing rock of Oamaru in New
Zealand, which is of Miocene age (Australasian Fossvls, 1914, p. 110).

a species of Aturia common to the older Eocenes of Britain,
Europe, etc.
McCoy next referred to the fossil as it occurred in Victoria
under the new name of A. australis, and regarded its stratigraphical
position as Lower Miocene, the deposits showing a resemblance to
the Faluns of ‘louraine, as well as to the beds of Bordeaux and Malta.
The results of a more complete study of Victorian specimens were
subsequently published by McCoy, giving excellent figures and a full
description. On this occasion the name was altered to A. stczae
(Sowerby, sp.) var. australis, with an acknowledgment, however, of
its close affinity to A. aturi from the Miocene of France. Its
veological distribution in the Victorian T'ertiaries was considered to
be from Oligocene to the Lower Pliocene, although mentioned as of
rare occurrence in the last-named formation.
It was pointed out by the present writer’ in 1915 that the
A. australis presented no differences of importance from the true
A. aturi of Europe, and therefore it should be known under the
latter name, a view which was fully confirmed in a verbal statement
by the late Mr. G. C. Crick.
The species has been also recorded from the Table Cape Beds of
Tasmania, where it was first recognized by R. M. Johnston under
the name of A. zezac, while all authorities are agreed that it occurs
as well in the Oamaru deposits of New Zealand.
In connexion with the New Zealand occurrence, it is of interest to
mention that Mr. A Hamilton ® has reported a very large example of
this shell, measuring 16inches in diameter, from some calcareous
greensands of the Waitaki River Valley, North Otago, which was
determined as A. ziczae var. australis, while zeuglodont remains,
Kekenodon onamata, Hector, were found in association. Both of
these fossils form part of the fauna of the Oamaru deposits which are
considered to be equivalent in age to the Janjukian rocks of Victoria ;
so that the Waitaki River Valley beds may be accurately regarded as
Miocene, more especially as Professor Park*® brackets them with the
Oamaru formation, which is Lower Miocene. According to Messrs.
Dennant & Kaitson’s* catalogue of Cainozoic Fossils of Victoria,
South Australia, and Tasmania, this Cephalopod has been recognized
from the following localities :—
Victoria: Brown’s Creek, Muddy Creek, Gellibrand River, Birre-
gurra, Lower Moorabool, Mornington, Mitchell River, Spring Creek,
Beaumaris, Royal Park Moone Ponds, and Apsley.
South Australia: Mount Gambier.
Tasmania: Table Cape.
The New Zealand occurrences, taken from Professor Park’s work,
already quoted, are as follows: Oamaru, Waitaki River Valley,
Waihao, and Kakanui, all these localities being in the South Island.

NEWTON: ON AYVURIA ATURI. 166
The distribution of this Cephalopod in other countries may next be
considered.
In 1825, under the name of Nautilus aturt, Basterot first described
the shell from the Dax! beds of South-Western France, founding his
description on Montfort’s old figure of Nautilite de Dax published in
1802. These so-called Dax beds are of Lower Miocene age, having
been regarded as Burdigalian by De Lapparent? and by Haug? as
Aquitanian. Bronn‘ established the generic name of Aturta in 1888
on Basterot’s species, but failed to properly unite the two names of
Aturia aturi until 1856.
Excellent examples of the species have been described and figured
from the Italian ertiaries by Dr. Sacco, who gives its geological
range as from Aquitanian to Helvetian.
Austrian specimens of 4. aturi have been figured by Hoernes
from the ‘‘ Schlier”’ deposits of Ottnang, which are recognized as of
Vindobonian (= Helvetian) age and equivalent to the ‘‘ Tegel” of
Malta.
Its occurrence in the Island of Malta was first referred to by
Forbes in 1844 as Mautilus zigzag, and although regarding it as
identical with the London Clay fossil, he was of opinion that it
belonged to the Miocene period on account of the Maltese deposits
bearing a resemblance to those of the South of France and Northern
Italy.
Sieeaientls Fuchs figured the shell from Malta as Nautilus
(Aturia) aturi, from the so-called ‘‘Badner Tegel”, which is
equivalent to the ‘‘Schher” of Austria, and therefore belonging to
the Vindobonian (Helvetian) division of the Miocene.
M. Lemoine has identified the species from Madagascar as Aturva
ef. aturt, in older Miocene rocks which he attributes to the
Aquitanian stage of that period.
Fairly recently, M. Fourtau has made known its occurrence in the
Burdigalian Beds of Egypt, which belong to the Lower Miocene.
Found also in South America (Chili), and determined as Aturza
ef. atur?, it has been reported by Dr. Moricke from the Navidad
deposits, which are considered equivalent to the Patagonian Formation,
and hence, according to Dr. Ortmann,’ may be referred to the Lower
Miocene.
So far as can be ascertained, therefore, Aturia aturt belongs
entirely to the Miocene period, and it is only in Australia that it
is said to extend to Pliocene times, having been found in the
Beaumaris Beds of the so-called Kalimnan division of the Tertiaries
! Tt should be understood here that at Dax itself there are no Miocene deposits ;
they really occur at St. Paul de Dax, which is about 15 miles from the
village of Dax, where the beds abound in shells and other organic remains
of Miocene age.

which McCoy identified as Lower Pliocene, an age which has been
since adopted by Mr. I. Chapman for those beds, although it is only
right to mention that the Kalimnan deposits were formerly regarded
as Miocene by Messrs. Tate & Dennant* and Hall & Pritchard.’
One of the most important members of the Kalimnan fauna is
undoubtedly that of Sealdicetus macgeei, described by Mr. Chapman *
in 1912. That genus, belonging to the Sperm Whale group of
Cetaceans, was originally discovered in the ‘*Crag Noir” Beds of
Belgium (Borgerhout), which are recognized as belonging to the
Anyersian* or uppermost Miocene, sometimes called Pontian or
Messinian. ‘The association also in the Kalimnan Beds of Carcharodon
megalodon, the well-known Selachian fish of Miocene origin, adds to
the assemblage, and certainly seems to suggest that those deposits
may be Miocene rather than Pliocene. With regard to the presence
of Oligocene in Victoria, first suggested by McCoy, the writer is still
‘of opinion that such beds containing no Nummulites, but numerous
Amphastegina and Lepidocyclina, belong to the oldest Miocene, which
in Kurope are included in the Aquitanian and Burdigalan stages of
that period. This Cephalopod, therefore, occurs in each division of the
Victorian Tertiaries, known as Ralianan anjukian, and Baleombian,
the last named bei ing the oldest. The foraminiferal evidence
worked out by Mr. Chapman furnishes complete data that the
Baleombian division is homotaxially equivalent to the Aquitanian
and the Janjukian to the Burdigalian, both of which groups form
the basal stages of the European Miocene. The Kalimnan series,
therefore, may represent the latest phase of the Miocene in
Australia, and comparable to the Pontian or Messinian of Europe.

THE MOLLUSCA OF MARSASCIROCCO HARBOUR, MALTA.
By G. Dersporr.
Read 13th June, 1919.
In nearly all the published lists of the Maltese Marine Mollusca no
locality is given for the majority of the species enumerated, notwith-
standing that locality is one of the most important points in
a faunistic list.
McAndrew published two lists of species obtained by him in these
waters in the Report of the British Association for 1850. For the
species enumerated in the first list, with the quantity of the
specimens obtained, he gives as a locality “A ground of sand and
stones at a depth of 40 fathoms 1 to 2 miles distant from the shore’’.
For the species on the second list, the locality given is simply
‘‘a sandy bottom 6 to 12 and 15 fathoms deep in the harbour of
Malta”’, while the frequency of occurrence is given for only two or
three of the species recorded.
In Mamo’s list, compiled by the late Dr. A. A. Caruana, the
locality is given in only a few cases. Such localities, however,
as well as several other statements made in this list, appear now to
be somewhat incorrect; this, nevertheless, may probably be due to
the great change which has taken place in some parts of our harbours
since Dr. Caruana published his list.
Similarly, the locality of only a few species is given in Benoit and
Gulia’s list published in J/ Barth of 1872, and the frequency of
occurrence of some of the species recorded has, we find, varied
immensely.
Up to the year 1912 I entertained doubts about many of the
statements made in the above-mentioned publications, and in many
cases could not agree with my friend the Contino Dr. A. Caruana
Gatto, who is undoubtedly one of our most accurate and reliable
naturalists (and to whom | am much indebted for help in malacology).
As to the frequency of occurrence of several species of mollusea in
our waters, many of the species which he considered common were
according to my experience rare; and, on the other hand, I had
collected a considerable number of other species which he considered
rare. Such a difference of opinion was, however, mainly due to the
fact that we had investigated different localities. Till that time
I had limited my dredgings to the harbour of Marsascirocco, whence
since 1896 my specimens had been for the most part collected ;
whilst Dr. Caruana Gatto and the late Dr. J. 8. Galizia had carried
out their researches in the Grand and Marsamuscetto Harbours.
Such a marked difference having then been observed in connection
with the frequency of occurrence of a good number of species, which
difference was evidently due to the diversity of their collection
in either time or locality, or probably both, and knowing moreover
that the various works which are being continually carried out in
several harbours must necessarily affect some of the species

inhabiting those localities, I thought that the results of my
researches which have been carried on systematically for the last
six years would be of some interest, especially to future investigators,
in this class of our marine fauna. I therefore begin by giving a list
of the species found by me in the locality where my first researches
were made, namely Marsascirocco Harbour.
This harbour faces the south-east. It extends more than 13 miles
inland, whilst its breadth is about 2 miles. The greatest depth is about
16 evra The bottom varies considerably, the coast is more or
less deeply indented, forming several beautiful inlets, so that a shott
description will be of some interest.
Leaving Delimara Point, which is the extremity on the right-hand
side, we enter the creek of Marsascirocco, a fishermen’s village from
which the whole harbour takes its name. This creek is about
one mile long and about half a mile broad. Its bottom is for the
greater part weedy, its innermost part being muddy. In the fish-
ponds which exist on the right-hand side ey Susea, “R. mier ometrica,
and Cerithium contcum are eyrcail in myriads, and Cardium rusticum,
which is very abundant in the muddy bottom of the creek, grows
to an exceptionally large size within these oe
The next inlet is Cala San Giorgio, or San Giorgio a Mare,
with its innermost portion commonly called “Tl Ghain”. This
double depression of the coast is separated from the creek of
Marsascirocco by a tongue of land, at the end of which is the
promontory of St. Lucian. Cyprea lurida is rather frequently found
on the shore below this promontory.
The bottom of the outer part of Cala San Giorgio is mostly muddy
and weedy, the shallow parts and the beach ‘being covered with
avery fine sand. Capsa fragilis once occurred in great abundance
here, but now not even its valves are to be met with. Zedhina
planata, though rather searce, is still obtainable in this sandy bottom,
and after strong sciroccos its valves can be picked up on the sandy
beach.
The bottom of I] Ghain”’ is either muddy or shingly. Capsa
fragilis was also once common to this locality, though only its valves
are now noticeable. According to the older fishermen two species of
Tapes were also common in this bottom; of these, however, there
is not the faintest sign at present. Cerithium lima is in some years
found in countless numbers im some weedy patches in this locality,
but in other years it somehow seems to disappear altogether.
A broad tongue of land called “Il Gzira” divides ‘11 Ghain from
the next bay, known as Birzebbugia, the finest bay of Marsascirocco
Harbour and a very popular summer resort. The bottom of this
place is composed of the finest silvery sand to be seen in these islands.
In it Mactra stultorum is generally found in good numbers. Zeddina
planata is also frequent, while Venus gallina and one or two species
of Donax have been known to occur also plentifully during some
years. Massa mutabilis is procurable in fairly large numbers from
this sandy bottom; the majority of the specimens, however, though
generally in fine condition, are dead, and mostly inhabited by

a peculiar hermit crab. Jssurella greca was for two consecutive
years (1912-13) common along the rocky portion of the beach of
Birzebbugia, but is now very rarely met with, and Mytilus minimus,
which once literally covered the rocky shore, appears to be almost
extinct.
Leaving Birzebbugia, after passing a straight and almost regular
rocky coast about a quarter of a mile long known locally as
‘*Ts-Salini?’ (the salt-pans), we come to Wied il Buni. The
nature of the bottom here varies also considerably. In some parts ©
it is shingly or muddy, in others rocky or weedy, whilst its inner-
most portion is encumbered with boulders of various sizes, mostly
embedded in patches of small pebbles and sand. Here dead
specimens of Zrochus adansont can be collected in fair numbers, and
with them shells of Gibbula nivosa are also frequent. Bornia
corbuloides, too, during some years is found in fair numbers adhering
to the larger pebbles; and amongst the weeds in the deeper portion of
this inlet Pinna nobilis is common. Beyond Wied il Buni there is
another straight rocky beach equal in length to the one from
Birzebbugia to Wied il Buni. This beach, however, has been lately
converted into a wharf. Along this part of the coast Murex
edwards and Pisania maculosa used to be found in large numbers,
with Zrochus turbinatus, 7. articulatus, and 7. divartcatus.
At the end of this tract there is the once beautiful cove of Cala
Frana, which has unfortunately been so modified that if cannot be
called beautifulany more. The character of the bottom of this little
bay is also varied, but for the greater part itissandy and weedy. Here
Solemya togata was rather common, but now it is very probably
extinct. Valves of Zupes nitens were also obtained here in large
numbers, showing that the species used to be common enough.
Next to Cala Frana comes another tract of rocky coast, which,
running down to the left end of the harbour, is known as Binghisa
Point. Along this shore Masciolaria lignaria is generally common,
and Purpura hemastoma is frequently met with.
The list of the species of Mollusca which have been met with in
Marsascirocco Harbour is as follows :—
Anomia ephipprium, L. Not common, found attached to stones,
shells, and other objects dredged from various depths.
2. Anomia patellformis, L. Very scarce ; its valves are occasionally
found in shingly corners.
3. Ostrea lamellosa, Broce. Valves are occasionally found along the
beach; the species, however, is undoubtedly rare in the
locality.
4, Spondylus gederopus, LL. Very rare. | have only met with this
species twice in the living state; its valves, however, are more
or less frequently dredged on gravelly bottoms, and are also
occasionally found on the sandy beaches.
Pecten varius, L. Some valves have been obtained from a
shingly and sandy bottom, 8 to 10 fathoms. J have not vet
met with a single living specimen,
