The Catalogue of the Cephalopodous Mollusca by Dr. A. H.
Foord, commenced in 1888 (two parts of which are
issued, the third part being now in the press), together
with the Systematic List of British Oligocene and Eocene
Mollusca by Mr. E,. Bullen Newton, in 1891, are the
only volumes already published on the fossil Mollusca in
this Department.
The present work by Mr. Gr. F. Harris, on Tertiary
Mollusca, commences a new Catalogue ; the first part
being devoted to descriptions and figures of the shells of
Australasia (exclusive of the Cephalopoda), to be followed
by other geographical series in the collection, of equal
interest.
Although thirteen volumes on Fossil Yertebrata, eight
volumes on Fossil Invertebrata, and three upon Fossil
Plants, have already been published by the Trustees, the
larger part of the Mollusca and Bryozoa, and the whole
of the Brachiopoda, Annelida, Arthropoda, Echinoderma,
and Ccelentera, remain to be recorded, as well as the
greater portion of the fossil plants, so that probably
not less than thirty volumes will be needed to contain.
even a brief account of these very varied and extensive
collections.

INTRODUCTION.
The Tertiary MoUusca of Australasia present many features of
special interest, both to geologists and zoologists. The remarkable
abundance and perfect state of preservation of the Gastekopoda,
especially of Victoria, enable us to shed much light on certain
questions relating to phylogeny, which cannot fail to assist the
zoologist as indicating the oiigin of many of the principal groups
of that division of the Mollusca, and as imparting some idea
of the past history of the modern molluscan fauna of Australasia
generally. The larval shells, especially, have proved to be
of great interest, and I venture to think that many of the
details concerning them as recorded in this Catalogue will prove
serviceable, not only from the phylogenetic standpoint, and in
regard to the early history of the individual, but as a contributii)u
to the systematic classification of the Gasteropoda. The phenomena
of growth in this division of the mollusca have never been studied,
except in regard to restricted groups; and I have occasionally
criticized modern methods that give undue importance (as it would
seem) to the number and disposition of plications on the columella,
the absence or presence of liriE within the outer margin of the
aperture, the relative length of the anterior canal when present,
and modifications in detail of external sculpture. These and
kindred phenomena aie frequently utilized by the systematist for
purposes of specific and even of generic classification, whereas
in many instances a careful study of ontogeny would show that
they were mere peculiarities either of the individual or as
characterizing a distinct stage of growth. I do not intend
to imply that the features of growth just mentioned are never
of importance for purposes of classification ; but until each case
is studied on its own merits, in other words until the ontogeny
of each has been carefully worked out, it is impossible to say
INTRODUCTION.
■whether any particular phenomenon observed is of value to the
systematist, or not. A phenomenon may be of the highest
importance in the classification of certain genera, and be of little
value from that point of view in reference to others. The study
of the development of the Gasteropoda would show better than
anything else what value is to be ascribed to any particular
structural feature in the shell, in that sense ; but little has hitherto
been attempted in that direction.
An exhaustive study of auxology cannot, obviously, be
chronicled in a Catalogue like the present; but I have seized
this opportunity of selecting the most promising species and
genera of Australasian Tertiary Gasteropoda from' the material
in the Museum, and, as far as is consistent with the plan of the
book, have detailed certain structures of general interest which
may hereafter prove of service to workers in elaborating the genesis
of the modern Gasteropod fauna of the antipodes.
To the geologist, also, particulars concerning the growth of these
Tertiary shells are not without their significance. It is very
difficult for paleontologists, by the methods now commonly adopted
in classifying the Mollusca, to say how much of a variation from
a normal type shall constitute a species : the personal equation
is always with us. And seeing that Tertiary beds are commonly
classified according to the relative percentage of extinct species
of mollusca found in them, and that for the reason just given
it is almost impossible to arrive satisfactorily at such percentages,
it seems to me that, rightly understood, the phylogeny of that
division of the animal kingdom is a broader and surer basis for
classification of the various horizons, and might be made to run
pari passu with the Lyellian method. Its most useful application,
no doubt, would be in reference to homotaxis. This suggestion is
to a large extent prompted by the great difficulty which geologists
experience in working out the synchrony of the Tertiary beds
of Australia, to this day a source of much controvei'sy between
them.
As instances of the application of phylogeny in matters of this
kind let me refer to pp. 17, 18, where in reference to the so-called
Pteropoda it will be noted that the assemblage of genera found
in certain rocks classified by competent authorities as Eocene is
not such as might have been expected in rocks of that age, when
the known history and origin of the Pteropoda are taken into
INTRODUCTION. IX
consideration. As a further illustration T may refer to p. 9G,
"where, after giving some account of the larval shells of the
VoLUTiDJK (p. 92 et sqq.) and the light they throw on the origin
and evolution of that family, I state that tlie development of these
larval Volutes in the majority of instances in specimens found at
the localities mentioned .... is much more advanced than
one would have expected to find in beds as old as the Eocene — that
is, on comparison with what is found in the true Eocene in other
parts of the world. And it would not be difficult to give other
evidence of the same nature. No doubt some families make more
rapid strides in one area than in another ; but it is surprising to
find in the Gasteropoda how uniform over large areas the rate of
progression has been in regard to many of the widely distributed
families. There is, for example, the genus that has survived from
early Mesozoic times, with hut little modification in the later stages
of its journey ; it has had its day, and has settled down as a more
or less fixed form. Such a genus is of little use for homotaxial
purposes, though eminently interesting from a purely phylogenetic
point of view. What we want to study specially for the purposes
of Tertiary homotaxis are those families, quite numerous enough,
the chief members of which, having parted from the main stock
in late Jurassic or Cretaceous times, arrive in the Eocene, with
strong tendencies to variation, and, at the same time, are rapid
travellers and become ubic|uitous, as is the case with many
prominent genera of the Australasian Tertiary Gasteropoda. But
this is not the place to enlarge on the value of phylogeny to
the geologist, and the subject is introduced here only as in some
measure the outcome of a study of the Tertiary MoUusca from the
Antipodes now catalogued.
In the foregoing observations special stress has been laid
on the study of Gasteeopoda, but it must not be understood
that the fossil Lamellibeanchiata are one whit inferior in
point of interest from the phylogenetic or the geological stand-
point. The want of sufficient suitable material in the Museum
for the study of the auxology of the Australasian Tertiary
LAMELLiBEAXcniATA, is the sole cause for the omission. It should,
however, be added that in many specimens the prodissoconch is
excellently preserved.
The n.imes employed to designate stages of growth of the
individual, and the sense in which they are applied in this work,
X INTRODUCTION.
are, as nearly as may be, those of Professor Alpheus Hyatt, ^
as amended by Messrs. S. S. Euckman and F. A. Uather.'' The
terminology alluded to is as follows : —
1. Embryonic. "This stage includes all individual history from
the ovum up to the time when the organism can be referred
definitely to its class." In the fossil state we can only have left
for investigation the hard part of the organism, which in the case
of the Gasteropoda is here called the Protoconch, and in the
Lamellibranchiata the Pyo(iissoeo7i'ch.
2. Brephic. This stage immediately succeeds the Embryonic,
and it is generally undei-stood that during it no specific characters
can be distinguished ; but this point will be discussed presently.
3. Neanic. "Luring this stage specific characters and all other
morphological features present in the adult, appear and undergo
development."
4. Eplielic. That stage denoting "the period of full develop-
ment of the individual, when all specific characters are clearly
recognizable."
5. Gerontie. "During this stage changes take place which are
due to gradual failure of powers." It is subdivided into : " a,
Catahatic stage, in which the individual loses its ephebic characters ;
and h, Hypodrophic stage, in which the continued loss of characters
causes pronounced reversion."
In view of the fact that so little is known concerning the
phylogeny of the Gasteropoda, I have found it somewhat difficult
in certain cases to apply this terminology satisfactorily. Por
instance, in the case of shells that are quite smooth it is hard
to say where the protoconch ends and the brephic stage begins ;
but in very many instances a characteristic varix is present,
denoting the termination of the former. The brephic stage, as
a rule, in reference to these fossils, was a short one, the growth
having been very vigorous immediately on the animal's escape from
the capsule, and conchological specific characters consequently
make their appearance at a very early stage.
Some of the more prominent results obtained from this study
of Australasian shells may now be refisrred to.

INTKODUCTIOX. XI
It ■will be noticed (p. 7) that I have retained Adaon in its usual
place, amongst the OpismoBRANcniAXA ; but it must be confessed
that this is done with some misgiving. It is generally concluded,'
judging from the structure of its shell and its persistent operculum,
that that genus should be placed amongst the lower Opisthobranchs;
but it should be observed that the earlier portion of the protoconch
is distinctly sinistral, and has all the essential characteristics of
the Pyramidellid^. On that ground alone one might feel inclined
to classify Aetceon, and possibly some of its associated genera,
amongst the Peosobranchiata. We should be strongly fortified
in so doing by the important discovery by Bouvier,- in a careful
anatomical investigation, that Aetceon has a twist in its visceral
nerve-loop, and is, consequently, streptoneurous. In view of
what is known of the general organization of the genus, even
in spite of the evidence afforded by the protoconch and the study
of the nervous system, we are hardly warranted, however, in
removing it from the Opisthobranchs ; and for the present it will
be safe to conclude that we are here dealing with inherited
streptoneury.'
The value of the elevation of the spire in the classification of
the C0NID.E is discounted by what we find in the ontogeny of
Conus cuspidatus (p. 32), where the amount of elevation is shown
to be merely a peculiarity of the individual.
The impossibility of satisfactorily diiferentiating Stcrcula from
Pleurotoma when dealing with fossil specimens, is insisted upon
(p. 37) ; and, incidentally, the position of the sinus as a prime
element in the classification of the Pleurotomid^ is criticized.
Although the majority of protoconchs in species of the Gastero-
poda appear to be smooth and without sculpture, many exceptions
are noted. In particular, Pleurotoma icangamiieiisis (p. 46) is
remarkable in that respect. The initial turn of the protoconch
is smooth and obsoletely striated, and this is followed by an obtuse
angulation, which rapidly develops into a bold, acute, median spiral
carina, with accompanying lineation. See also Columharium acan-
thoslephes (p. 52), Telcoclulus gracillimuin (p. 65), Harpa ahhreviata

XU INTRODUCTION'.
(p. 81), Latlriis tatei (p. 147), Leucozonia staminea (p. 151),
Pseudovaricia mirabilis (p. 160), and Murex otwayensis (p. 177).
Althougli Tve occasionally find that the main features of the
sculpture of the adult are foreshadowed even in the protoconch,
that is by no means a general rule. The protoconch of Pleurotonia
alta (p. 45), for instance, is perfectly smooth, yet in the brephic
stage a most pronounced peripheral carina makes its appearance ;
on the other hand, in P. wanganuiensis (p. 46) the strong spiral
ornament obtains from the protoconch to the ephebic stage, though
profuse additional ornament was suddenly produced in the brephic
stage. On this evidence, and seeing how closely allied the two
species are in some other respects, one would assume that the latter
species most probably descended from an earlier stock of the former.
By way of contrast we find in Bathytoma angustifrons (p. 49)
and Morio gradatu (p. 201) that but few of the main features of the
ornament in the adult were foreshadowed even in the brephic stage,
and that ornament is not of a permanent character, but was modified
at the caprice of the individual. That, and similar evidence given
in this Catalogue, points pretty conclusively to a general rule that
may be established (at least, so far as these Australasian fossils are
concerned, and it is possibly of much wider application), namely :
that when the main features of the ornament are foreshadowed
in the early brephic stage, and especially when they obtain even
in the protoconch, that ornament may be regarded as of value
in the determination of species ; but when, on the contrary, the
ornament does not make its appearance until the late neanic stage,
and is not, even in an elementary sense, completed until what may
be regarded, by analogy, as the early ephebic, that ornament merely
characterizes the individual, and is only of negative use for the
purposes of classification.
The size of the protoconch is very variable (e.g. Cancellaria
wannonensis, p. 66), as is well known, even in the offspring
of a single individual ; that difference being commonly attributed
to carnivorous proclivities on the part of the larger specimens when
in the embryonic stage. In this connection it is noteworthy that
the size of the protoconch does not seem to have much influence
in determining the size of the shell in the adult. The larger
protoconch is not ver}' frequently, it would seem, accompanied
by the production of a larger adult shell than comes from a much
smaller protoconch, that is, in the same species. There are,
INTRODUCTION.
however, exceptions to tliis, and correlatively it may be noted that
the shape of the protoconch occasionally determines the general
shape of the shell. In Bathytoma angustifrons (p. 49), for instance,
the Museum specimens show that the elevation or depression (as
the case may be) of the turns of the protoconch to a large extent
determines the relative elongation of the growth of the whole shell,
in that particular species.
Evidence is given (pp. 95, 96, and description of the species
of Scaphella) that some of the Australasian Tertiary Volutid^
possessed horny protoconehs ; and the classification of that family
as deduced from a study of the larval shells, together with some
account of the origin and development of the groups they represent,
will be found (p. 92 et sqq.). Cf. Fusus hezagonalis (p. 131) in
this connection.
The ontogeny of Mitra multisiilcata (p. 120) forms an interesting
study. As a result of the details of gi'owth, it is shown that the
number of columellar plications is not necessarily of value in
classification in such a genus as Mitra ; for in the brephic stage
there were only two plaits, and the suspicion of a third, whilst
in the ephebic no fewer than five are observable.
A very remarkable mode of growth is recorded in reference to
Tylospira coronata (p. 222) ; whilst Cerithium apheles (p. 224)
is full of interest. The shell in the latter exhibits longitudinal
costfe in the brephic stage, which are lost in the neanic, but
reappear strongly in the ephebic, only to die out again in the
gerontic stage. There is thus a high possibility of this species
having descended from a well-marked longitudinally costate stock,
with a tendency for its descendants to assume a much plainer type
of ornament.
I have stated in an earlier part of this Introduction that, although
it is generally understood that during the brephic stage of growth
no specific characters can be distinguished, it was desirable to
discuss the matter. Some of the observations just made prove that
the shell is often highly sculptured in that stage, and many other
examples are recorded in the text. It is by no means rare to find
that the chief ornament relied upon for the classification of the
species (in regard to individuals) suddenly makes its appearance
in the brepliic stage, and, not infrequently, starts abruptly from
the termination of the protoconch. A glance through the plates
accompanying this work will, perhaps, help to make this observation
INTRODUCTION.
clearer. Dr. Jackson's investigations' led him to the con-
clusion that characters almost inseparable from those of the
adult frequently make their appearance in the brephic stage of
the moUusca. In view of these facts it seems desirable to modify
the general statement that during the brephic stage no specific
characters can be distinguished. As a rule, no doubt, that statement
is perfectly accurate, and the brephic stage is unquestionably well
defined in the Gasteropoda as a whole ; but a little qualification
seems necessary. I have found that the greatest difficulty in
defining the brephic stage is in those cases where a strong varix
has been thrown up at the conclusion of the embryonic stage, and
it seems right that that should be so. Por the varix certainly
indicates a pause in the growth of the shell, and it is reasonable
to assume that during that pause the animal was passing through
the brephic stage, but did not continue to make the normal shell
of that period, except partially, it may be, in some instances.
I have even doubted whether in certain instances the varix
alluded to was not, in fact, the only manifestation of the growth
of the shell during the brephic stage.
Turning now to some other points brought out in this Catalogue,
it may be noted that it introduces frequent changes in nomen-
clature, especially in regard to genera and subgenera. Many
well-known names, I am sorry to say, have disappeared as the
result of bibliographic research. But I am not proud of having
made these changes — they were inevitable if the rule of priority
must be applied.
In particular, I have been at some pains to discover the names of
the type species of both genera and subgenera, in consequence of
which a new interpretation has, occasionally, had to be placed
on a well-known group. Some new genera and species are
proposed; and species hitherto described have been considerably
revised in regard to their generic position. In the description of
species my general plan has been to give only the salient features,
usually in the nature of a short diagnosis, where the species had
formerly been fully treated of ; but where the material in the
Museum collection permitted, and the species had hitherto received
but scanty notice, it has been dealt with at greater length,

Some difficulty has occasionally been experienced in assigning
species to their correct geological position in the Tertiary. In.
regard to the Australian "Eocene" and Miocene I have, where
possible, followed the classification of Professor Tate in his various
works quoted, although, as will already have been noticed,
I have considerable doubt whether the "Eocene" of that continent
is really homotaxial with that of North-Western Europe. Again,
in certain localities where two formations occur, as at Muddy Creek,
Trclissick, etc., it has sometimes been doubtful from which horizon
the particular specimens being catalogued came. In such cases
I have been much assisted by the useful list of Muddy Creek fossils
drawn up in Mr. John Dennant's memoir^ on the beds in that
locality, which has been quoted from time to time. Again, Sir
James Hector's list^ of New Zealand localities with their geological
horizons have proved valuable in the same connection ; whilst
Professor Button's Catalogue ' has of necessity been i-eferred to on
many occasions. Nevertheless, there are a few specimens from that
colony, the exact provenance of which I have not been able to fix,
as will be observed ; such specimens have, for the most part, been
in the Museum for many years, and the name of the locality,
which they bear, may possibly represent a place where a camp was
temporarily made. The collection from Parimoa appears to come
from two horizons, the Miocene and Pliocene, and in the case of a
new record for that locality it has been found impossible to give the
geological age with certainty. At Wanganui, again, both Pliocene
and Post-Pliocene beds are found ; in general it has not beea
difficult to assign a particular species from this locality to its correct
horizon, but there are exceptions. These, and similar points, I
must leave to Colonial geologists, who alone, by study on the spot,
can satisfactorily clear them up. The locality of Limestone
Creek, Glenelg river, Victoria, is here called Post-Pliocene, instead
of Newer Pliocene ; I believe it will ultimately be found to be
younger than the true Pliocene.
It should be explained that by " Australasia " throughout this
work is meant, the Australian continent, Tasmania, New Zealand,
and the Chatham Islands.

XVI INTRODUCTION.
This ■work will not embrace the description of the Tertiary
Cephalopoda in the British Museum, as they are being catalogued
by Dr. A. H. Foord and Mr. G. C. Crick'; but it may be mentioned
that so far as Australasia is concerned only two Tertiary species,
viz., Aturia atari, Basterot, var. australis, M'Coy, and Nautilus
geelongensis, Poord, are found in the collection, and they have
already been dealt with.-
Finally, I must express my indebtedness to several friends who
have assisted me, from time to time, during the preparation of this
Catalogue. Foremost stands Mr. Edgar A. Smith, whose courtesy
in permitting me frequently to consult the modern moUusca in the
Zoological Department of the Museum, and for much advice in
regard to matters of nomenclature, I most thankfully acknowledge ;
Mr. R. Bullen I^ewton has also rendered me assistance in regard to
nomenclature, for which I tender him my best thanks ; Mr. B. B.
Woodward has on several occasions given me the advantage of his
extensive knowledge of bibliography, which has been of signal
service, and for which I am greatly indebted to him ; Mr. C. D.
Sherborn has kindly permitted me to refer to the MS. of his
Index Animalium. Professor Tate, of the University of Adelaide,
kindly sent me a collection of specimens and copies of his publi-
cations on the Tertiary moUusca of Australia, which have been
of much use ; whilst I am indebted to my friend Mr. H. W.
Burrows for his ready assistance in reference to the classification
of mollusca. To Miss G. M. Woodward I must also tender my
thanks for the preparation of the beautiful drawings which adorn
this Catalogue,

Genus HELIX, Linnajus {em. Miiller).
[Linn. Syst. Nat. ed. 10, 1758, p. 768; Miiller, Verm. Terr. Fluy. vol. ii.
1774, p. 12.]
Several recent writers have referred to H. pomatia, Linnaeus,
as the type of Helix ; there seems to be no reason, however,
for departing from the emendation of Miiller, as recognized by
authors such as Pfeiffer,' who made an exhaustive study of the
genus.
Type. — Helix lampas, Miiller.
Helix tasmaniensis, 6. B. Sowerby.

The description by Sowerby being based on very imperfect
materials, the following amplification may be quoted: — "Shell
thin, globosely conical, umbilicated ; whorls 4h, rapidly increasing,
oniamented with fine obliquely-arcuate striaj, crossed by fine spiral
lines . . . , flatly convex above, convex below, last whorl
tumid and slightly descending in front ; suture somewhat im-
pressed, spire depressly conical ; umbilicus deep, narrow, scarcely
one-sixth of the diameter ; aperture oblique, ovately lunate ;
' Monog. Helic. Viv. 1«18, p. xv.
peristome simple ; margins slightly approximating, basal margin
slightly dilated and reAexed."— Johnston, 1880.
Only one fragmentary specimen of the numerous examples in
the Museum bears any trace of shell structure ; the remainder
are internal casts. The ornamentation of the shell fully bears
out Mr. Johnston's description, except that no spiral lines are
to be seen on the fragment alluded to. The casts present consider-
able variation in the elevation of the spire, occasionally, indeed,
being somewhat depressed, when they closely resemble the living
ffelix confusa, Pfr., of Queensland, North Australia, etc. In the
last-mentioned shell, however, certain adult forms attain to con-
siderable spiral elevation, especially in the specimens in the
Museum from North Australia. Judging from the sculpturing
and general aspect of the casts, it is highly probable that
IT. tasnianiensis should be classed in the subgenus Rhytida, but
the materials are not perfect enough to enable one to be quite
certain on this point.
Mr. Johnston {op. cit. 1880, p. 89) describes two new species
of Helix from the same locality as the Museum specimens come
from : one of these, H. huxleyana, is very minute ; and the other,
S. geilstonensis, is described as orbicularly depressed, the whorls
being markedly convex below ; a variety of H. sinclairi is also
created which has, inter alia, a narrow umbilicus. Neither of
these is represented in the British Museum Collection.
Dimensions (of the type specimen). — Height 22i mm. ; breadth
34 mm.

Genus LIPARITS, Albers.
[Die Heliceen, 1850, p. 172.]
Test ovately conical, with an obtusely conical spire, whorls to
the number of 6 or 7, aperture ovate, peristome simple, acute,
I
columella twisted so as to form an obscure but somewhat callous
plication, the slight callosity almost covering the very minutely
perforated umbilicus, and extending more or less over the body-
whorl towards the posterior portion of the aperture.

1888. Bulimus gunnii, Johnston, Geol. Tasmania, pi. xxiv. fig. 7.
This species is represented by one example only in the British
Museum — the type figured by Mr. Sowerby. It is a cast of the
interior, and no vestige of the shell itself appears thereon. Mr.
Johnston was only acquainted with fragments of the cast, l^ever-
theless the present writer is of opinion that the structure of the
shell may, to some extent, be inferred from a careful examiuation
of the type specimen. From the deepness and general aspect of
the sutures it is certain that the test must have been very thin,
and, as in certain other representatives of the genus Liparus, the
lines of growth no doubt existed both interiorly and exteriorly.
These latter are strongly reflected in the cast under consideration,
from which it is legitimate to conclude that the shell was by no
means smooth, although Mr. Sowerby says " leeviffatis?"
Unfortunately, a large part of the cast is imbedded in the hard
calcareous matrix in such a manner as to mask the phenomena of
the aperture, so that the reference of the species to the genus
Liparus is not altogether without doubt. When the specimen is
compared with the living Liparus leeuivinensis, E. A. Smith,'
of N.W. Australia, however, the doubt almost decreases to the
vanishing point, for, as far as can be judged from an internal
cast, the two must be of the same genus, and, indeed, they are
closely allied specifically. The chief specific difference is the more
conical and tumid shape of the fossil. On comparing the latter
with the living L. kingi, Gray, from King George's Sound, which

and the lines of growth are more oblique.

An imperfect specimen in the Museum collection presents the
generic characters of Placostylus, but its condition precludes the
possibility of referring it accurately to any known species. It

The inner margin of the aperture, in certain individuals, is
extremely callous and folded into a rough plication in the vicinity
of the umbilicus ; the latter is broad and keeled outwardly.
The species is frequently quoted as A. nux-avellana, Chemnitz;
but as that author's designation of it is not binomial it cannot be
accepted, and the description as a whole must be ignored. Martyn
in 1784 figured the species under the name of Limax crenata,
without description. The first author to regularly describe it
was Bruguiere, and he included it under Bulimus, a circumstance
which Schumacher overlooked, apparently, in creating the generic
name. Deshayes and Milne Edwards express their willingness
to acquiesce in the genus AmpuUacera proposed by Quoy and
Gaimard, but, as in other cases, adhere to the description given by
Lamarck.
It inhabits salt marshes near the sea, or lives in brackish water.
Professor Hutton, in 1879, published particulars concerning its
anatomy, amplifying those previously given by Quoy and Gaimard,
in which he remarks that " The animal lives between tide-marks
in salt or brackish water on mud flats in sheltered bays. When
found at all, it is always found in large quantities. It is very
sluggish in its habits, and feeds on the vegetable matter contained
in the mud, passing large quantities through its alimentary canal.
Although air-breathing, it will live for a week or ten days in
fi-esh water, and for more than a fortnight in salt water, without
being exposed to the air."

This species is described as follows by Mr. Tenison- Woods : —
" Shell oblong, ovate, solid, apex acute, smooth only at the
extreme summit; whorls seven, cancellate with very distinct
spiral liraj, much finer longitudinal striae ; interstices rounded or
punctate, lii-aj on the last whorl broad and subdivided by a fine
groove, longitudinal striae subdistant (so that the interstices are
transversely oblong) and passing occasionally over the lirse, so as
to make them subgranular, especially at the anterior margin ;
aperture subauriform, posteriorly acutely attenuate ; peristome
anteriorly everted and recurved, plait conspicuous, solid, obtuse."
The species is compared with A. pinguis, D'Orbigny, of the
European iliocene, from which it may be distinguished in being
narrower, and in the disposition of the columellar plication. The
8
size of the plication, its situation, and the excavated columella
behind it, recall the genus Solidula to some extent, though it
materially differs in only possessing one plication, which is not
bifurcate. Mr. Tenison- Woods does not give a figure of this
species, but from his description the identification appears certain ;
it is now figured.
Dimensions (of the figured specimen). — Length 9|^ mm. ; breadth

The columella of this genus carries two plications, the anterior
prominent and bifid, the posterior comparatively inconspicuous
when the shell is entire ; between them the columella is spirally
excavated. These, amongst other characters, distinguish Solidula
from Adeeon.

This is a typical example of the genus. It is spirally and
closely sulcated, and longitudinal strise are distinctly seen in the
grooves. On one of the British Museum specimens several flat
ridges between the sulci bear a minor sulcation. The sutures are
not deep ; the outer margin of the aperture is extremely thin, and
is not sinuous anteriorly.

[Journ. Acad. Nat. Sci. Philad. (n.s.) vol. iv. p. 294.]
Several authors have confounded Tornatellma with Solidula, but
it may be readily distinguished from the latter by the marked
depression on the anterior portion of the aperture ; by the difference
in disposition of the columellar plications, which are brought more
prominently forward, the foremost anterior plication being situated
relatively nearer the anterior extremity of the shell ; and by the
greater thickness of the shell in the neighbourhood of the outer
border of the aperture, which is frequently crenulated. These
characters suffice, also, to justify separation from Actceon, sensu
stricto. It may be remarked, that the fossil usually known as
Actceon simulatus, from the Barton beds, is undoubtedly a re-
presentative of this American genus in England. Tornatellcea,
moreover, has sometimes been confused with Tornatella, Lamarck,
which is a synonym of Actceon.
Tijpe. — Turnatellcea hella, Conrad.
Subgenus TRIPLOCA, Tate.
[Journ. Roy. Soc. N.S.W. vol. xxvii. 1894, p. 186.]
The principal difference between this and Tornatellcea, sensu
stricto, consists in the former having three columellar plications
instead of two, the two anterior of which are situated close
together ; the spire is longer, and the outer border of the aperture
is not crenulated.

1 0 ADELACT^ON.
Shell thick, spirally linear sulcate ; sulci not punctated, close
together and varying in prominence, sometimes obliterated.
M. Cossmann states that this species possesses minute punctations
in the spiral sulci, but neither of the specimens in the Museum
exhibit that peculiarity, though when seen under the microscope
slight irregularities exist where the faint lines of growth intersect
the sulci. The shells are slightly more tumid than that repre-
sented by the figure given by Professor Tate; the other specific
characters, however, are identical in the main, and the present
writer hesitates to make a specific distinction on such unimportant
diiferences. The species is evidently very variable; even the
deep sulcation bordering the suture (so prominent in the speci-
mens selected for description by the last- mentioned author) is
occasionally reduced to such dimensions that it barely surpasses
in size the ordinary spiral sulcations. The latter, too, are by no
means always persistent over the whole of the whorls, one of the
Museum specimens showing the body-whorl sulcated over two-
thirds of the surface only. It would seem that when ornamented
in the manner lastly described, the sulcation bordering the suture
is stronger, as though the missing sulci had gathered together
at that point. On the other hand, when sulcated throughout, the
sutural sulcus is relatively smaller — a phenomenon observable also
in certain European forms of Act^onid^, where it seems to be
merely an individual characteristic. Q'he visible portion of the
protoconch (Plate I. Figs. 2a-l) consists of about H turns, and
is remarkably small, hiding the sinistral nucleus — at least in the
Museum specimens.

stria3, lines of growth inconspicuous; columella slightly excavated
and carrying a small but well-marked plication ; columellar border
expanded and frequently covering the small umbilicus.
This genus resembles Actaon in its general characters, but may
be readily distinguished when the earlier portion of the protoconch
can be satisfactorily determined ; the protoconch, as a whole, is
not so well developed as in Adceon.
In proposing this new name for Myonia, M. Cossmann remarks
that the fossil forms slightly differ from the living, and he bases
a new description and diagnosis on a Miocene species, Acteeon
papyraceus, Basterot, from the neighbourhood of Bordeaux, quoting
that species as the type of the genus. But, in substituting a
generic name for one preoccupied, it is desirable to conform to
usage by quoting as the type of the genus that appertaining to the
genus displaced ; therefore the type species proposed by the French
author alluded to should be superseded by that referring to Myonia.

Protoconch (Plate I. Figs. 3a-b) small, earlier portion hidden
by later turns in many specimens, but comparatively free in the
one now figured. It is smooth and polished ; more elevated than
in A. papyraceus, and is implanted obliquely on succeeding whorls.
Shell as a whole elongate ; aperture less than half the total length
of the shell ; whorls slightly turriculate, smooth, with minute
spiral strias, which become more prominent on the anterior portion
of the body-whorl.
The classification of this species, as remarked by M. Cossmann
{op. cit. supra), is a matter of doubt ; the embracing character of
the last whorl is distinctly that of the Act^onid^, but the earlier
part of the protoconch is different to that of Adelactaon, which,
sensu stricto, is obtuse, and is implanted in such a manner as
to render its sinistral character hardly perceptible.

the surface and closing in antero-posteriorly, farthest apart in the
median portion of the whorl, closest together towards the apex ;
lines of growth conspicuous on the smooth exterior and in the
thin spiral grooves, causing the latter to assume a minutely
punctated appearance ; aperture extending the whole length of
the shell, constricted posteriorly, expanded, curved, and produced
anteriorly; inner margin furnished with a conspicuous and slightly
reflected smooth band ; in consequence of the thinness of the shell,
both striae and lines of growth are seen in the polished interior of
the aperture.
Mr. John Dennant, in giving ' a list of species of mollusca found

Tate as Scaphander fragilis. As that has, apparently, neither been

The specimens in the Museum are larger than the average of

Mr. Johnston describes this species as follows : — " Shell white,
shining, minute, conical, sub-turreted, of about 6 rapidly increasing
■whorls; whorls convex, ornamented by regular, distant, punctate,
spiral sulci, about 12 on last whorl ; under lens broad, distant,
obsolete, transverse lirae may be traced ; suture deeply impressed ;
columella abbreviate, with two thick, tortuous folds, the lower
being the larger ; aperture roundly notched posteriorly and
anteriorly ; outer margin thick and reflexed, forming a broad
varix continuous with the last tortuous fold of columella." He
does not give a figure of the shell, but the description agrees
generally with specimens in the Museum. It may be added that
beyond the two columellar folds alluded to, a third one exists
posteriorly, the direction of which is approximately at right angles
to the others, and, as seen in perfect specimens, it resembles a
" tooth."
Some specimens from Muddy Creek are but veiy faintly striated,
the columellar callosity being thick and partly spread over the
body-whorl, from which it is sharply defined. The protoconch
of those from the locality mentioned is very small, composed of
a turn and a half, smooth and somewhat obtuse.
R. lactea may be distinguished from the living R. denticulata,
Gould, of Port Jackson and elsewhere in Australia, in that the
latter is more tumid, the anterior canal is more deeply cut, the
columellar callosity being much drawn out, whilst the spiral
lineations are closer together.

LIMACINID^. 17
Family LIMACINID^.
The anatomy of the soft parts of Pteeopoda has led Dr. Paul
Pelseueer to the conclusion ^ that pteropods are not entitled to
be regarded as a class of mollusca of the same value as the
Cephalopoda, Gasteeopoba, Scaphopoda, and LAMELLiBEAifCHiATA.
Pteropods, he believes, are not primitive mollusca, but are a derived
and recent group, and he completely abstracts certain Primary
fossils usually referred to the Pteeopoda from that group, as
represented by living forms. Boas had arrived- at a similar con-
clusion, though not on such abundant material. Dr. Pelseneer
discusses the matter at some length {op. cit. p. 90), and expresses
the opinion that real pteropods had no existence as such until the
commencement of the Tertiary epoch. He bases his arguments
on comparative anatomy, embryology, and palaeontology, in that
section dealing with the origin and phylogeny of the whole group.
He finds that the pteropods are Gasteeopoda in which the adap-
tation to pelagic life has so modified their external characters as
to give them an apparent symmetry ; that they do not constitute
a distinct subclass, nor even an order. They belong to the
Tectibranchiate Opisthobranchs, and they differ less from Tecti-
branchs than these differ from the other Opisthobranchs. And,
he is of opinion that the Thecosomata to which the Australian
fossils presently to be described may be referred, have descended
from the Bdlloidea ( = Cephalaspidea).
The general classification of the Pteeopoda amongst Opistho-
branchiate mollusca is here adopted, but without prejudice as to
the disposal of pre-Tertiary fossils usually relegated to the group,
the consideration of which does not fall within the scope of the
present work.
It is not a little remarkable as a phase in the evolution of
the Pteeopoda, that immediately the Thecosomata as a group
was well established, members of it became extremely numerous
in the Lower Tertiaries of Australia. But the assemblage of
genera is not such as might have been expected in rocks
as old as the Eocene, and it is highly probable that, regarded

from the evolutionary standpoint of the Pteropoda alone, the
Australian " Eocene," as exemplified by the Lower beds of Muddy
Creek, Schnapper Point, etc., is younger than the Eocene of
typical districts like the London, Hampshire, and Paris basins.
A very common genus, for instance, in the Australian beds
mentioned is Vaginella, which, as will be seen hereafter, has
a distinct Miocene facies, and it is found in typical beds of
that age in Europe and America. Stijliola, again (when rightly
interpreted), is rather a Miocene than an Eocene subgenus ; as for
Spirialis, its range in time, from the Middle Eocene to the present
duy, imparts no evidence of homotaxial value.
It will be observed that Styliola is here included as a subgenus
of Clio ; neither its embryonic nor its structural differences entitle
it to rank as a genus. Its structural features go to show that
Styliola is much more nearly related to Clio (^sensu stricto) than to
Creseis ; the forms included under the latter designation have
retained some of the more archaic characters of the LiMACiNiDiE.

Limacina is universally regarded as a genus established by

be noticed that he refers merely to " Les Limacines"; the author
who really established the genus was Lamarck, as above quoted.
The last-mentioned author, however, did not give the name of
the species correctly.

Shell umbilicated, thin, and shining ; spire depressed to the

the peristome is slightly reflected in its vicinity ; surface of shell
ornamented with fine lines.
Australian authors include this species in a genus Spiralis ;
it is presumed that Spirialis is intended. Dr. Pelseneer divides -
Spirialis, Eydoux and Souleyet, into two groups, according to the
presence or absence of an umbilicus, and other characters. The
species above described, following that classification, falls into
the genus Limacina.

Its rounded sides and dorsal groove serve to distinguish this
species from C. licarinata, Tate, found in the same beds. Near
the summit of the shell is a conspicuous inflation, whilst the
apex is much swollen and abruptly tapers to a fine point. Pro-
fessor Tate's figure barely does justice to this structure, and it
is interesting enough to demand another figure, which is now
given (Plate I. Figs. 6«-5) as seen under a microscope with a
one-inch objective.
The phenomena in the neighbourhood of the apex recall the
genus JEucMlotheca, Fischer, to some extent, but many fundamental
differences exist. In particular, C. rangiana has no reversed or
collareted border round the aperture ; whilst its pronounced
longitudinal sulcus, extending from the aperture almost to the
apex, is very distinctive. The whole shell is somewhat compressed
dorso-ventrally, and its almost smooth and polished surface is
ornamented with oblique transverse striations.
Professor Tate remarks that, compared with shells of the living

aperture, proportionately greater breadth, and by its abruptly
tapering apex.

This species, which is very common in beds near the base of
the section at Muddy Creek, has been aptly compared by Professor
Tate to V. depressa, Basterot. The present writer, who has found
large numbers of the latter species at Moulin de Lagus, the
Coquilliere at Leognan, and other localities near Saucats, south
of Bordeaux, is enabled to state from comparison of abundant
material of both the Australian and European species mentioned,
that V. eligmostoma is narrower, longer, more depressed in pro-
portion to its size, and more prominently constricted beneath the
expansions of the aperture. The representation of V. depressa as
having simple margins meeting at an angle on either side of the
aperture is not borne out by the facts, though the margins are
not sinuated to the same extent as in the Australian species. The
22 TJMBEACULtTM.
author of the latter remarks that the shell is angulated at the sides
and sculptured by very fine arched striae descending to the lateral
angulations. "The aperture is narrowly oval-oblong, with trun-
catedly rounded ends ; each lip has a median curvature bounded
on each side by a broad insinuation." The apex is in nearly all
cases well preserved. The shell is very variable in length, some
specimens being much narrower in proportion than others ; such
differences may be adjusted, however, in reviewing a large number,
and are not of specific value.

The genus is generally called Umhrella, but, as the synonymic
references above indicate, Umhraculum has priority. The designa-
tion "Ombrelle," if it were not a mere list name, could not stand,
in consequence of its being French, and not Latin. The term
Operculatum created by Linnaeus ^ and brought on by the brothers
Adams cannot be accepted, first because it was not made in a
binomial sense, and secondly as it was proposed prior to the date

of the tenth edition of Linnaeus' " Systema Naturae." Acardo,^
commonly quoted as being synonymous with Umhraculum, is said
by its author to be a bivalve ; from the figure given it might be
the epiphysis of a whale's vertebra.
M. Cossmann^ states that Vmbrella has priority over Umhraculum,
as it was proposed by Chemnitz in 1788, whereas the latter dates
from 1817. On referring to the joint work of Martini and Chemnitz
that observation is hardly borne out. Martini^ alludes to "Umbella,"
but in his description^ he is clearly not binomial, and did not
intend to name a genus Umhella ; he rather calls it Lepas, as
" Lepas vertice et limbo,'" etc. And a few pages farther on' the
same kind of thing is described as ^^ Lepas Indiea vertice,''^ etc.
Subsequently Chemnitz^ refers to " Umhella Chinensis, testa In-
tegra," etc. ; though in the explanation of the plates the term is
abbreviated to " Umhella Chinensis." As these authors were not
binomial, their work must be ignored; and Umhraculum should
be adopted.

Neither of the specimens in the Museum presents a perfect
protoconch, but Professor Tate remarks that it consists of " a
relatively large papillary pullus of two turns ; the first turn of
the pullus subglobose, with the tip reverted and immersed, much
broader than the next two or three whorls." The sutures of the
shell are slightly canaliculated and distantly bordered by a linear
sulcation ; the whorls are ornamented with transverse curvilinear
ridges and a few indistinct spiral striae most conspicuously de-
veloped in adult specimens.
This species has considerable analogy with certain European
Miocene forms of Terehra — in particular T. perhisa, Lamarck,
from the Langhian beds south of Bordeaux. It is narrower than
that species, however, and the whorls are flatter and more turri-
culate. It is allied also to the living T. cingulifera, Lamarck,
from the Philippines, China, etc.

The specimen in the Museum is too mutilated for minute
description. The posterior portion of the later whorls have a
narrow ante-sutural band ; the plications are narrow, slightly
bent, and subnodose, and between them are very fine and close
reticulations.

The sutural band is not so deeply impressed as in typical
specimens in the Museum from Tasmania, as found living, whilst
the body-whorl is more convex ; these differences may constitute
a variety from which the living forms may have descended, but
they are not worthy of specific rank.

The protoconch (Plate II. Figs. \a-l) of this species is subacute
and composed of three convex turns. The whorls of the shell are
much constricted posteriorly, and between the constriction and the
suture there is a row of tubercles ; the remainder of the surface
of the whorls has distant rugose ribs which are angulate, and
the whole presents rather the aspect of certain forms of Drillia
than of Terehra. That it ought not to be classified with the
Pleueoxomid.^, however, is clear from the general phenomena of
the aperture.
It diff'ers from T. mutica, Tate, from the same locality but of
27
Eocene age, in the whorls being more angulate, the anterior canal
being more excavated, and in other minor features.

Family CONID..S.
Genus CONUS, Linnaeus.
[Syst. Nat. ed. 10, 1758, p. 712.]
Shell convolute, turbinate; aperture narrow and long, edentulous ;
columella smooth.
An attempt to divide the Eocene fossils of this genus into
subgeneric groups based on observations made on living examples
of Conus, must always, the writer believes, be attended with great
uncertainty: for the genus itself had only just been established;
and although in a very unstable condition, it had not yet had full
opportunity of modifying, with development in diiierent directions.
No doubt, to a large extent, certain features of modern groups of
Cones were conceived in Eocene times, but they were not sufficiently
well differentiated to enable the species to be allocated clearly to
the subgenera as established on living species. Conus was pregnant
with evolutionary possibilities in the early Eocene. Nevertheless,
the writer has essayed a subdivision in spite of the difficulties and
uncertainties existing.
Ti/pe. — Conus marmoreus, Linnaeus.
Subgenus LEPTOCONUS, Swainson.
[Malacology, 1840, p. 312.]
The author describes Leptoconus as follows : — " Shell light,
conic, sometimes striated ; spire elevated, acute, concave ; the
basal whorl carinated, detached, and sinuated above, and con-
tracted near the suture." Other characters which seem to be
fairly persistent in this group are the deeply-cut canal bordering
the suture and the more or less staged convolutions.

Protoconch (Plate II. Pigs. 2a-l) composed of two smooth
volations, the earlier of ■which is somewhat oblique and inflated.
The spire of the shell proper is of variable height, in some
specimens being comparatively depressed and in others so elongated
as to be one-third the length of the shell. Spire-whorls with an
obtuse, thick shoulder and ornamented with closely-set, spiral striae,
which persist over the whole surface of the body-whorl also, being
especially accentuated on the anterior half. The body-whorl
varies in shape from pyriform to elongate ovate, the peripheral
keel defined anteriorly by a linear constriction, posterior to
which there are one or two threads on the peripheral band. The
aperture is narrow, with a comparatively shallow anal sinus.
The range of variation in this species is so great that innumerable
"varieties" could be established. One of them, as pointed out by
Professor Tate, closely resembles C. deperditus, Bruguiere, of the
Eocene of North-western Europe.
This species partakes of the characters of both Leptoconus and
Lilhoconus ; it has been assigned to the former subgenus on account
of its elevated and staged spire and striated surface.

This species differs from C. ligatus in being more elongate,
■whilst it is minus the rim-like keel of that species, and the
lineatious on the whorls of the spire are not conspicuous. The
staging of the whorls is a peculiar feature ; when in the brephic
and neanic periods of growth there is little or no attempt at
staging, but in the adult, and especially in senile forms, the
anterior whorls drop very sharply. It is highly probable that
this catabatic phenomenon is the precursor of the establishment
of an elevated spire in its descendants ; but that is a point
which cannot be definitely settled until the phylogeny of the
Gasteropoda has been worked out.

Conus (Leptoconus) ne^wtoiii, sp. nov.
[Plate II. Figs. ?,(i-d.']
Protoconch small, composed of two and a half smooth turns,
indistinctly striated with growth -lines anteriorly ; posterior portion
slightly oblique with reference to the axis of the shell.
Spire elevated, acute, convex, about one- sixth the total length
of the shell ; spire-whorls seven in number, staged, excavated,
spiral lineatious bold and continuous, growth-lines prominent,
sinuated. Keel sharp and plain, not being crenulated even in
the brephic stage. Body-whorl elongate, ornamented throughout
its length by distant spiral sulcations which are punctated where
crossed by the lines of growth. Aperture long and narrow ; outer
margin thin and arched ; posterior sinus very deep ; anteriorly
the aperture is somewhat dilated and the columella is slightly
twisted.
The elongation and narrowness of the body-whorl are dis-
tinctive features. Its nearest ally in the Australian Tertiaries
is C. extenuatus, Tate, which, however, is broader, whilst its
body-whorl is not so long, its periphery is not so sharply keeled,
the earlier whorls are crenulated, and the ornamentation of the
spire differs. C. newtoni closely resembles C. sieholdi, Reeve,
30
living in the seas round the coasts of China and Japan, but in the
modern form the whorls are not so much staged and the spiral
lineations are not so well marked ; the principal point of difference,
however, is the shape and shallowness of the posterior sinus.

Protoconch (Plate II. Pigs. 4a^b) composed of three smooth
turns implanted obliquely with reference to the axis of succeeding
whorls; the initial portion is exceedingly small in comparison
with the anterior turns. These latter are depressed and deeply
canaliculated. The shell proper has an elevated spire with six
whorls, which are somewhat staged, slightly excavated ; and spiral
lineations are not prominent, except towards the anterior half of
the body-whorl. It is noteworthy that in the brephic stage the
periphery of the body-whorl was obscurely crenulated, a character
which disappeared, however, as the neanic period was reached.
Aperture narrow, slightly expanded in front ; outer margin thin ;
with a shallow posterior sinus.
This species presents characters of no less than three subgenera :
by its very elevated spire and the obscure crenulations it recalls
Conospirus, which does not appear to stand on a very firm basis ;
its protoconch presents the features of Lithooonus as represented in
the Australian Tertiary by C. dennanti and C. piillidescens ; but
the general contour of the shell and the staged whorls reflect
Leptoconus, to which subgenus the species is here referred.
Specifically it has a near ally in C. hrocchii, Bronn, of the Italian
Pliocene.

Conus (Leptoconus) convexus, sp. nov.
[Plate II. Figs, oa-d.']
Protoconcli composed of two smooth turns, the initial portion of
■which is lateral and immersed ; much elevated above the remainder
of the shell. The whorls of the spire, five in number, are slightly
convex, and are thus not excavated as in other species mentioned ;
they are ornamented by five or six deeply-cut sulci, somewhat
irregular in places owing to the intersection of growth marks ;
these latter, however, do not approach tessellation. The whorls
are not staged, but the suture is distinctly canaliculated, especially
as the growth approaches the ephebic stage. The body-whorl has
an elevated band at its periphery, which is rugosely lineated ;
its whole surface is covered by small, undulating, irregular sulci,
which broaden anteriorly and are interrupted by sinuous growth-
lines. Aperture long, narrow, its two margins parallel with
each other ; outer margin thin, curved, and distinctly crenulated
within ; anal sinus broad and comparatively shallow, inner margin
straight.
Its protoconch is very different to that of C. pulhdescens ; and
the convexity of the whorls, deep sulci, canaliculate suture, and
crenulated margin of the aperture, are highly distinctive. On
comparison with C. complicatus, Tate, in addition to the characters
just mentioned, it will be observed that C. convexus is broader,
and the spire less elevated, whilst the ornament is peculiar to it ;
moreover, the whorls are not staged, neither is the sinus deeply,
arcuately notched.

p. 194, pi. vii. fig. 1.
1893. Conus cuspidatus, Tate and Deunant, id. vol. svii. pt. 1, p. 221.
Protoconch (Plate IT. Figs. 6a-b) conspicuously elevated, rising
to a sharp point, composed of four to five slowly and regularly
increasing turns, forming a very distinctive feature. Spire of the
shell proper with seven to eight volutions, slightly concave and
deeply lineated spirally.
In the brephic stage the spire is much elevated in all the
specimens examined, and this character may he perpetuated to
the gerontic stage, or the whorls may become flatter and less
elevated during the neanic, and absolutely depressed during the
later stages of growth. Such a wide range in elevation of the
spire is not often observable in Conus ; the amount of elevation
is merely an individual peculiarity. This may be noted by those
who seize upon this unstable property as a subgeneric character
and often allow it to influence them in defining a species.
Body-whorl either obtusely or acutely angulate at the periphery,
depending on the elevation of the spire ; lines of growth well
marked, spiral striae plainly developed anteriorly. Aperture
narrow, dilated in front, channelled behind ; columella twisted,
bordered by an elevated ridge in young specimens, and very pro-
nounced in the catabatic stage where the anterior portion is usually
much fractured, owing apparently to difficulties of growth. The
columellar twist leads to a slight constriction of the body-whorl.

This species may be distinguished from C. cuspidatus, amongst
other things by its extremely characteristic and prominent proto-
conch (Plate 11. Pigs. la-h). This is very large, composed of
33
three turns, somewhat turbinate, with deeply canaliculate sutures.
The protoconch is oblique with reference to the axis of the shell.
The spire of the shell pi'oper is not much elevated, its whorls are
narrow, separated by a linear suture, ornamented with a few
spiral threads and closely-set sinuous lines of growth. Body-
whorl sharply keeled at the periphery, and covered with fiat spiral
threads which become obsolete with age, except anteriorly.
The figure accompanying Mr. Tenison-Wood's memoir above
cited refers to a young shell, and is practically unrecognizable.
The interpretation placed upon it by Professor Tate is here adopted.

This species does not appear to be described, except in the
explanation of the plate above cited, where the following words
occur: " Conus dennanti, sp. nov. {C. piillulescens, var., Tate)."
The protoconch (Plate II. Figs. 8«-5) differs from that of
C. piillulescens in not being angulate, or turbinate ; it is com-
posed of three smooth, convex turns, imbedded in the crown of
the shell, being in fact the only part whicli stands above the flat
surface produced by the convolution of the shell-whorls proper.
This upper surface is much depressed, has linear sutures, and is
boldly, spirally striated. The periphery of the body-whorl is more
sharply keeled than any other Australian Tertiary Conus; the
surface of the whorl is covered by rather closely-set spiral linea-
tions and sinuous growth-lines. Aperture very narrow, outer
34
border parallel with the inner, but slightly dilated anteriorly ;
columella twisted in front.

This species may be readily distinguished from all other Australian
Tertiary Conus, by the peculiar, rugged aspect of the body-whorl
caused by the inter-crossing of growth folds and the irregular
character of the distant spiral lineations and ridges. The spire
is much depressed, with canaliculated sutures; the periphery of
the body- whorl is sharply keeled ; the anterior portion of the
columella is twisted and prominently lineated. The protoconch
is not well preserved in the Museum specimen, but it evidently
had the general features of that of C. pullulescens, though more

Protoconch (Plate IT. Figs. 9a-h) conical, moderately elevated
and composed of two smooth turns, somewhat similar to that of
C. heterospira. In the brephic stage, and, possibly, to the
commencement of the neanic, the whorls of the spire are coronate,
but as the adult form is reached these disappear and the shoulders
become rounded. Mr. Tenison-Woods was only acquainted, ap-
parently, with young forms of the species, and the figure in his
memoir cited above does not convey a correct idea of the shell, as
each whorl is represented as being carinate and nodosely crenulated.
Professor Tate has traced the young forms to the adult and firmly
established the species. The spire is elevated, composed of eight
whorls striated spirally above. The body-whorl is also spirally
striated, the striae being most conspicuous on the anterior half.
Aperture narrow, posterior sinus shallow and following growth-
lines ; columella slightly twisted anteriorly.

Conus (Chelyconus) catus, Hwass.
1792. Conus catiis, Hwass, Eney. Meth. (Vers) t. i. pt. 2, p. 707.
Shell bulbous, spire convex, striated above ; body-whorl finely
striated on the posterior half, and having deep spiral sulcations
anteriorly. Aperture narrow, but widening in front and some-
what dilated ; posterior sinus conspicuous ; columella twisted
anteriorly where a well-marked ridge or fold is produced.
The species differs from the earlier C. raJphi, with which it
is closely related, in being much broader anteriorly and by the
prominent coluraellar fold. The specimens in the Museum are
not well enough preserved to show the protoconch or the condition
of the shell in the brephic stage.
This species has living representatives over a large geographical
area, including the Red Sea, Mauritius, Java, China, Xew Cale-
donia, and Polynesia generally, and it is interesting to find it as
a fossil.

Family PLEUROTOMID^.
In assigning the species here described to their systematic
positions in the Pleueotomid^, it may be remarked that in view of
the present unsatisfactory condition of the classification of many of
the so-called genera and subgenera in the family, some of the con-
clusions anived at must, of necessity, be of a tentative chai'acter.
The group has been divided into subfamilies according to the
presence or absence of an operculum, and the nature of that
when present. The systematic position of many of the species
is dependent on the situation of the sinus, its depth, and so forth.
The length of the anterior canal, details of ornament, peculiarities
of the radula, and the like, have also been permitted to rank high
— even as generic characters.
The family as a whole is not of very great antiquity, its main
features having been carved out in the Eocene ; whilst many of
its broad characteristics were not evolved until the Miocene, or
early Pliocene. Possibly, no group of the moUusca has been
so prolific in yielding so many diversified forms in such a short
space of geological time. The variation of individuals in the
living as well as in the fossil state is often so wide as to render
it impossible to satisfactorily define the limits of range permissible
in species. That difficulty, combined with the latitude of the
personal equation, has led to the establishment of innumerable
so-called species of the Pleurotomid^, which appear to the writer
to be founded merely on ontogenetic characters. The problem,
already difficult with the living forms, is intensified when the
fossils are considered. Here we have no operculum to assist,
and many other points utilized in the classification of modern
Plkukotomid^ are missing. Shorn of the characters of their
opercula, the chief difference between Pleurotoma and Surcula,
for example, lies in the form and position of the sinus ; in the
former genus it is deeper, and is placed farther away from the
suture than in the latter. If these characters were in any way
constant they might be rendered useful ; but, as it is, we are
38 PLEUEOTOMi.
left without any material conchological differences between the
two genera mentioned, and the assignment of any but typical
si^ecies to either of them must remain doubtful. It is highly
probable, however, that a special study of the protoconchs, and
the mode of growth of the shells as found in the fossil condition,
will assist in clearing up many difficulties.
Very few of the Australian Tertiary species of PLEUEOTOiiin^
have been described ; of these some have never been figured, and
the descriptions of the remainder are often so imperfect as to
render identification impossible. Several forms new to science
are now recorded.

being slightly inflated, whilst the anterior turns are obtusely
carinate. Shell narrow, elongate ; whorls ten in number, slightly
convex, and having several bold, irregular, spiral threads or

Pleurotoma septemlirata, sp. nov.
[Plate II. Figs. lOa-i.]
Shell large, fusiform, tumid ; protoconch small, smooth, devoid
of ornament, terminating abruptly at its junction with the shell
in the brephic stage ; whorls eleven in number, suture canaliculate
and bimarginate, rugosely spirally Urate ; there are seven principal
spirally striated lirae on the penultimate whorl in the adult, but
at younger stages of growth they are fewer in number, decreasing
gradually to four ; the body-whorl is irregularly Urate throughout.
Between the large compound liration on the margin of the suture
anteriorly, and the elevated ridge denoting the position of the
sinus, is a broad, deep sulcation, which, like the sulci between
the lirce, is finely spirally striated and interrupted by lines of
growth. Aperture large, broad, ovate, contracted anteriorly ;
outer margin thin, sulcate within, crenulated or serrated, arcuate ;
sinus broad, deep, situated distantly from the suture ; columellar
margin smooth, curved, slightly callous in senile individuals ;
canal very short and broad.
Typically this species has some analogy with P. murndaliana,
but is larger, more tumid, has a shorter canal, and is not sub-
granose, whilst the deep, broad sulcation in front of the suture
is characteristic. Its great range of variation is remarkable, and
might at first sight lead to the establishment of several new
species. The type specimens, as above indicated, are strongly
Urate, but with sufficient material these may be traced almost
to the vanishing point, some individuals, indeed, being only very
faintly striated, and to all intents and purposes smooth. Pari
passu the shell is shorter and more tumid, presenting the aspect
of Pusionella, though it could not be classified with that genus,
on account of its deep sinus, amongst other things.

Pleurotoma trilirata, sp. nov.
[Plate III. Figs. l«-rf.]
Shell small, elongate. Protoconch large, composed of two and
a half smooth turns ; the earlier portion is much depressed, and
even in the initial part the suture is canaliculate and marginate ;
at a later stage the protoconch is longitudinally costate and
subnodose at the periphery, and this continues up to the brephic
stage, where it gives way to the bold spiral lirse which form the
sole ornamentation of the whorls in subsequent stages of growth.
Whorls six, flat, suture canaliculate and marginate ; spiral lirae
three in number on the penultimate whorl, with a smaller lineation
between the posterior two, which becomes more accentuated on
the body-whorl. The latter is boldly lirated throughout ; lines of
growth inconspicuous. Aperture small, pyriform ; outer margin
arcuate ; sinus shallow, situated not far from the suture ;
columellar margin smooth, not callous, slightly twisted in front ;
anterior canal very short.
The most interesting feature of this species is the highly
sculptured protoconch, which differs from that of any other
Australian form here described. The longitudinal costse, how-
ever, precede the spiral lirse as in some other species of Pleurotoma.

Protoconch composed of one and a half smooth, shining whorls,
the anterior portion of which is obtusely keeled medially ; this
keel develops into a strong feature in the brephic and neanic
stages, but on approaching the adult is not so clearly marked.
Shell small, fusiform ; whorls obliquely cancellate, the transverse

Pleurotoma subconcava, sp. nov.
[Plate III. Figs. 2a-J.]
Shell large, elongated; from 11 to 12 whorls; the later portion
of the protoconch (the only part preserved in the type specimen)
is distinctly longitudinally ribbed ; beyond the sinuous fracture
denoting the commencement of the brephic stage these costae
suddenly cease and give way to spiral lineations, with a prominent
median sulcation indicating the position of the sinus. The whorls
throughout the brephic and neanic stages are flat, with a deeply
impressed suture, but in the adult stage they become convex, and
have a postero-median subangulation at the periphery. Between
this and the suture is a well-marked concave depression. The
ornament consists of closely-set spiral lineations, which are nearest
together in the depression alluded to ; the suture is margined by
one or two lineations bolder than the rest. The lines of growth
are fairly conspicuous, producing rough, irregular corrugations here
and there ; these are most noticeable in the neighbourhood of the

Pleurotoma salebrosa, sp. nov.
[Plate III. Figs. Za-d.']
Shell fusiform ; whorls eight in number, in the young growth
flat ; in the neanic and ephebic stages subangulately convex, rapidly
increasing in size ; protoeonch two smooth turns, globose, the
later turn being wider than the succeeding whorl. Ornament
consisting of from 13 to 14 deep, undulating sulcations on each
whorl of the spire, the body-whorl being sulcated throughout in
a similar manner ; lines of growth not very conspicuous, but the
surface of the shell is peculiarly, distantly corrugated, the corru-
gations being five in number on the penultimate whorl, and rising
into indistinct, broad, oblique ribs. Aperture pyriform, much
contracted in front ; outer lip thin, slightly sulcated within ; sinus
situated about half-way between the peripheral subangulation and
the suture, broad and shallow ; columella smooth, striated vertically,
but not callous, twisted in front ; anterior canal long, broad at its
extremity.
This shell differs from P. stihconcava in being relatively more
tumid, having a larger aperture and fewer whorls ; by the oblique
broad, corrugated costse ; and by the position of the sinus, which in
this case is indicative of Surcula of authors. The protoeonch, also,
is widely different, as will have been noticed.

ribbed, anteriorly the ribs become obsolete ; shoulder of last whorl
obtusely angulate ; entire external surface of whorls covered with
small, closely-set spiral liraa ; aperture broad, the broad sinus being

From the position of the sinus this species might be classed with
Surcula ; but in view of the difficulties of making use of that
variable characteristic (which in the case of the present species
ranges between the shoulder and the suture, but is nearest to the
latter), as already stated, no attempt is here made to separate

Shell fusiform, elongate ; protoconch turbinate, composed of
three smooth turns, the suture of which is marginate. In the
brephic stage the margination is much accentuated, and at a later
period of growth gives way to a row of small, distant granules.
In the same manner, the median, tuberculated carina of the
adult commences in the brephic stage by large obtuse uodulations.
The shell is thus described by Mr. Tenison- Woods : — "It is a
polished shell, with whorls angular in the middle, supporting
44 PLEUEOTOMA.
a single, somewhat distant series of coarse, blunt, somewhat square
tubercles. These are exactly oa the line of the sinus, and at each
side the lines of growth curve away from it. The sinus itself
is deep, broad, and somewhat quadrate. The aperture is long and
round, rather square posteriorly, and the canal is long and only
slightly curved."
The marginate character of the protoconch is noteworthy ; from
its metamorphosis in later stages of growth, it would appear that
the species has descended from a stock in which the suture was
accompanied by a large flat keel, though no shell of that character
has been recorded as occurring in the Australian Tertiaries.
Another point of interest in this species is its compound character :
it possesses the tubercular sutural coronation and produced spire
characteristic of Clavatula, and shows what value is to be placed
on that feature ; the special nature of the peripheral carina and
the arcuate, long canal somewhat resemble Surcula; whilst the
position of the suture and other general features of the shell
recall Pleurotoma. Clearly it was pregnant with evolutionary
possibilities.

small spiral lineations, crossed by rather conspicuous growth-lines,
and accompanied by a peculiar damascened structure. Protoconch
composed of two smooth turns, the anterior being subangulate
and vertically striated ; terminating abruptly against the shell of
the brephic stage, which is longitudinally, obliquely costated

anteriorly; outermargin thin, undulating; sinus broad and shallow;
columella covered by a thin deposit of vertically striated callus,
twisted anteriorly ; canal long, curved, broad in front.
This shell agrees with others here described in being longi-
tudinally costated in the earlier stages of growth, which costse
disappear in the adult. It has the aspect of what is generally
included under Surcula, but the sinus is far removed from the
suture, as in typical Pleiirotoma.

Protoconch composed of two elevated smooth turns ; whorls
six in number, smooth, or only marked with growth-lines, very
strongly and acutely keeled at the periphery, and with one or
two inconspicuous spiral lineations, as an individual characteristic,
above or below the keel ; body- whorl subangulate in front, denoting
the position of growth as the suture became developed ; aperture
ovate, contracted anteriorly, and terminating in a rather long canal;
sinus deep, situated between the keel and the suture, but nearer
the former ; columella twisted, covered with a smooth, thin deposit
of shelly enamel.
On conchological grounds this species might be relegated to
Surcula, but, as previously remarked, any such reference must
always be exceedingly doubtful with fossil specimens. An
interesting point is that, whilst many strongly keeled species
of PLEUEOTOMiii.a; bear traces of angulation in the protoconch
which lead up to the keel in subsequent stages of growth,
P. alta is without this in spite of the fact that the carina is
most strongly developed in the brephic stage. This species has
considerable analogy with Surctila jani, Bellardi, from the Upper
Miocene of the Piedmont basin. The specific name alta is here
proposed in substitution for pngoda, preoccupied, as iudicatud.

Professor Hutton describes this as follows: — "Shell fusiform,
the spire longer than the body-whorl. Whorls strongly spirally
ribbed, and obliquely longitudinally ribbed in the centre. From
13 to 16 longitudinal ribs in a whorl. Suture very finely obliquely
striated, and with a spiral rib. Aperture oval, canal short and
recurved."
Specimens in the British Museum agree very well with this
description, but the figure given in the memoir above cited
represents a more tumid variety. The protoconch (Plate II.
Pigs. Wa-h) is most remarkable, and merits detailed description.
Of the four specimens in the collection, two exhibit the
characteristic fracture or undulation at the termination of growth
of the protoconch. As thus defined, the latter is composed of
from two and a half to three turns; the initial turn is smooth
and obsoletely striated, and this is followed by an obtuse angulation
which rapidly develops into a bold, acute, median spiral carina,
with a conspicuous lineation both above and below it, and another
bordering the suture. Up to this point, no longitudinal costse or
other ornamentation are developed, and if the growth had con-
tinued in the same manner a shell somewhat resembling P. alia
would have resulted. Instead of that, however, the brephic stage
is characterized from its commencement by the profuse ornamen-
tation, suddenly introduced, which obtains in the adult. This
should prove of material value in working out the genetic relation-
ships of the group.

By the short canal and longitudinal costae this shell presents
some analogy with Drillia, but it differs in the position of the
sinus, which is distant from the suture, and in the absence of
a posterior callosity on the columellar border. The length of the
anterior canal is not of much value in systematics, and in some
species of Fleurotoma may only indicate sexual differences. The
ribs and position of the sinus are characteristics recalling Surcula.

Tryon,* in reviewing the genera of Pleueotomid^, follows
Pischer'' in including Dolichotoma as a subgenus of Genotia, and
remarks that in common with Pseudotoma, Oligotoma {=Astheno-
tomd), Roumiltia, and Cryptoconus its characters are not important.
The American author alluded to does not monograph the fossil
species, nor does he explain the matter further, so that it is
impossible to arrive at his precise meaning. Professor Tate^
remarks that he was not satisfied that Dolichotoma is clearly
definable from Genotia, and therefore describes the Australian
species which follow as Genotia.
I^ow the type of Genotia is Murex mitriformis, Wood, which
is an elongate shell with oblique suture, narrow aperture, straight
columella, and wide and shallow sinus situated some distance
in front of the suture. The type of Bathrjtoma {olim Bolichotoma)
is more solid and turbinate, it has a wider and relatively shorter
aperture, a very deep sinus situated near the shoulder of the whorl,
its outer margin is highly arcuate, and its columella is distinctly
twisted. These are differences enabling the two genera to be
distinguished at sight.

Australian Tertiary species are, perhaps, examples of Bathytoma,

states that they have not a twisted columella. As the possession
of this is a typical generic factor, it may be observed that the
French author's statement is not correct; and though, it is true,
the figures accompanying Professor Tate's memoir ^ do not exhibit
a twist or plication, that author expressly states- that the specimens
have a slightly twisted columella.

Protoconch composed of two turns, somewhat oblique and
slightly longitudinally striated anteriorly. The elevation or
depression of these turns to a large extent determiues the
relative elongation in the growth of the whole shell. Where
it is depressed, the whorls tend to become broad and strongly
keeled; where, on the other hand, it is much elevated, the
carinations are not so sharp and the shell becomes very long.
It is interesting to observe also that but few of the main features
of the ornament were foreshadowed in the brcphic stage, and the
extremely diversified character of that ornament as the animal
became adult is mei'ely an individual characteristic, of no value
for systematic purposes. If the shells of a number of very young
specimens be compared, no one would have any difficulty in
relegating them to a single species; but as they get larger the
ornament tends to become so variable that many malacologists
would feel inclined to admit the extreme types of variation as
of specific rank. Professor Tate's description and figure refer
to a commonly prevailing form.
The sinus in this species is unusually deep, though not more
so than in some forms of the type species from the Pliocene of

the Mediterranean area. Comparing the shell with that of
B. catapJiracta of the Upper Tertiary of Italy, the latter will be
found to be relatively more elongate and not so rich in ornament,
whilst the body-whorl is, in the majority of specimens, more
tumid. The aperture of the Australian shell is somewhat
narrower. But it is unquestionably a near ally of the European
species mentioned ; and bearing in mind the great range of varia-
tion in both shells, it would even be desirable on many grounds
to unite the two species.
The living B. atractoides, Watson, of the Philippines is, perhaps,
synonymous in its general characters, though in that case the
name proposed by Mr. "Watson would take precedence. The
present writer hesitates to deal with the matter, however, as only
one specimen of B. atractoides is at his disposal, and that has
a much broader, though shallower sinus than any of the fossil
examples here quoted. This species may also be compared with
B. viabrunnea, Dall (sp.), living in the West Indies.

Protoconch slightly more oblique, but is, otherwise, similar to
that of the other two species mentioned. The shell may be
readily distinguished by its more fusiform character ; the spire-
whorls carry a rough angulation, between which and the suture
posteriorly is an excavated area with a number of spiral lineations.
The lines of growth being rather prominent, a species of oblique
reticulation is set up, and where these pass over the peripheral
angulation, rudimentary compressed tubercles result. The spiral
lineations of the body-whorl are prominent, and occasionally
granulose. The sinus is not quite as deeply cut as in the other
species mentioned ; aperture pyriform, constricted posteriorly ;
columella erect and bearing a well-marked fold.

as the type of Fusus, the type of the present genus does not,
even conch ologically, resemble it very closely.
The inclusion of this genus in the Pleukotomidje rests almost
exclusively on the character of the radula, which is distinctly
toxoglossate. The passage can be understood, conchologically,
if Ancistrosyrinx, Dall, be studied in that connection. If we
exclude Pleurotoma cedonulli, Reeve, which, as Professor Dall
shows,^ should be classed in the genus last mentioned, then the
living examples of Columbarium would appear to belong exclusively
to the seas of Australia and Japan.

This is a very typical example of the genus. Its protoconch
(Plate III. Pigs. 6a-J) is composed of two smooth turns, the earlier
of which is bulbous and the later carinate medially. This carina-
tion in the brephic stage is developed to an abnormal extent, and
is even spinose, as in adult individuals.
The spire is turreted ; the whorls, six in number, are " ex-

This species has considerable analogy with the living C. pagoda
var. spinicincta, Von Martens, of West Australian seas, and it is
highly probable that C. acanthostephes is merely a synonym of
that ; in the absence of an example of a shell of the living species
alluded to, the present writer hesitates to further deal with the

Protoconch of the same general character as in C. acanthostephes,
but not so bulbous and relatively much smaller. A remarkable
feature is, that in the brephic stage, and immediately after the
animal emerged from the capsule, bold longitudinal ribs make
their appearance ; but as the neanic stage is approached these
disappear, and are not resuscitated in the adult. These costae,
which seem to be connected with longitudinal striae on the
protoconch (seen when the latter is well preserved), are nodosely
angulate medially. The growth of the shell from the neanic stage
onwards exhibits no variation worthy of record.
The shell differs from C. acanthostephes in having what Professor
Tate calls the " coronal fringe " well developed by the absence
of "prickles," and the plain character of the area from the
peripheral angulation to the suture. The shell as a whole is

not so ornate ; and the protoconch differs, as already described.
It is closely allied to C. pagodoides, "Watson, obtained by the
"Challenger" expedition off Sydney in 410 fathoms of water;
from which it differs in having a much smaller protoconch and
a non-spinose anterior canal.
Fusus craspedotus, Tate,^ is stated by its author to belong to the
same group as his, F. foliaceus (= Columharium foliaceum). Several
examples of that species are in the Museum collection ; and the
present writer, from a careful examination of that and other
material, believes that the differences in the respective proto-
coachs, and the general phenomena of the aperture and ornament,
are sufficient to warrant generic separation. At the same time
it must be remembered that as the status of this genus largely
depends on the character of the radula, and as that part of the
animal is not found in fossil specimens, the classification of fossil
species which conchologically resemble the recent forms, must
always remain doubtful.

Protoconch composed of two tumid, shining turns, the posterior
portion being laterally immersed. The longitudinal costae, which
become so well developed at later stages of growth, commence
in the brephic by prominent tubercles. Shell regularly and spirally
grooved ; suture hidden by an elevated prolongation of the posterior
part of the whorls, between which and the ribs referred to is
a rather broad and flat space. Aperture very small ; outer margin
greatly curved, sinus deep and near the suture ; columella covered
by a leaf-like expansion and having a tuberculose callus posteriorly ;
anterior canal short and somewhat twisted.
This species is said to occur both in the Eocene and Miocene
beds of Muddy Creek. Mr. Tenison- Woods states (o/;. cit. p. 228)
that it considerably resembles D. beraudii of the south-east

Drillia oblongula, sp. nov.
[Plate III. Figs. 7fl-i.]
Shell small, turreted, fusiform ; protoconch witli two smooth
subangulate turns, closely resembling that of D. trevori. Whorls
six in number, longitudinally obliquely costated in the brephic
and neanic stages, closely spirally lineate, the lineations being
irregularly granular at the points of intersection of the growth-
lines; typically the costated whorls are deeply sulcated spirally,
and in later stages of growth a lineation is developed in each
sulcus. On arrival at the adult stage this lineation becomes
more conspicuous, but never attains to the same proportions as
the originally-formed lineations. These latter persist over the
whole body-whorl down to the tip of the anterior canal. Suture
marginate and accompanied, anteriorly, by a broad band, medially
sulcated, denoting the former positions of the sinus. Aperture
narrow, but inflated towards the middle ; outer margin arcuate,
the deep, broad sinus being situated near the suture ; inner margin
covered by a thin coating of enamel ; columella slightly twisted ;
anterior canal very short.
This differs from D. integra, Tenison- Woods, in not being con-
spicuously ribbed, and by the absence of costae in the adult, though
the shell is somewhat corrugated longitudinally at that stage. It
differs also in not being broadly sulcate above, nor regularly spirally
lirate ; whilst the outer margin is not thickened to an appreciable
extent. A form from the same locality has smoother whorls.

proper, which, even in the brephic stage, is distinctly angulate,
and possesses the general characteristics of the ornamentation of the
adult. Whorls live in number, spirally lirate throughout, the lirte
being larger and farther apart in front of the peripheral sub-
angulation. The growth-lines develop into equidistant, oblique,
inconspicuous costae, best seen in the early stages of growth ; and

very conspicuous, deep and bordered by the posterior extension
of the outer margin, which covers the suture in that region, and is
reflected towards the thin enamel of the inner margin ; a prominent
denticle is placed on the latter near the sinus ; columella somewhat

broad shallow sinus near the suture ; columella excavated ; canal
short, truncate.
None of the species here described are typical examples of the
genus ; they appear to be intermediate between Baphnella {seiisu
strido) and its subgenus Pleuroiotnella, Yerrill. They are not
included in the latter, by reason of the sinus not being deep enough,
and from the absence of the "smooth concave surface" between
the shoulder of the whorls and the suture. By some authors they
would possibly be classified with Bela ; that genus, however,
appears to be much misunderstood. It does not seem to be
recognized that the type of Bela (Leach MS.), Gray,' is Murex

Surface covered by closely -set spiral lineations, remarkably regular
from the brephic stage onwards, and crossed by conspicuous growth -
lines, which occasionally produce minute granulations at their
points of intersection, but are for the most part more clearly
defined in the sulci between the lineations referred to. Aperture

terminated posteriorly and curved anteriorly where a short
broad canal exists ; outer margin thin, moderately curved, sinus
broad but shallow, and occupying the whole of the sutural

Protoconcli similar to that of B. sculptilis, but somewhat canali-

Shell tumid ; whorls five to six in number, angulate at the
periphery, between which and the suture is a deep depression ;
suture canaliculate and marginate ; surface of the whorls uniformly

obtuse posteriorly ; outer margin very thin, sinus broad, but
shallow between the suture and the periphery ; inner margin

sulcations are visible posteriorly ; columella excavated, twisted

three or four minor ones being situated between the more prominent
of them. Aperture broad, rounded posteriorly and truncated

excavated.
This species does not appear to have been described before,
though figured by Professor Tate, as above indicated. It may

64 TELEOCHILUS.
TELEOCHILUS/ nov. gen.
Protoconch (Plate III. Figs. I2c-d) large, from one to one and
a half depressed turns, spirally and longitudinally striated from
the initial portion onwards, the spiral striae developing into well-
defined sulcations as the shell passes from the brephic to the neanic
stages of growth. Shell as a whole elongate, the aperture being
much longer relatively than, the spire ; whorls slightly convex
and spirally sulcated throughout, lines of growth well marked ;
suture typically canaliculate ; aperture with thin, erect, outer
margin, constricted posteriorly, and broad towards the anterior ;
columella plain, with a thin deposit of callus through which
the sulci appear.
It is difficult to satisfactorily classify this genus. By its general'
configuration it has considerable analogy with Daphnella ; but
may be easily differentiated by the unique characteristics of the
protoconch, and the absence of a posterior sinus. The last-
mentioned circumstance might be taken advantage of to remove
Teleochilus from the Pleueotomii)^, did we not know that the
possession of a sinus is not an absolutely necessary qualification
for inclusion in that family.
In some respects Teleochilus recalls certain forms of Mitra, but
it has no columellar plications, nor even the semblance of a fold ;
whilst its protoconch is distinctive. At the same time, it approaches
the genus Dilaphus, Philippi, which, although deprived of folds
on the pillar, is classified with the Mitrid^, chiefly on anatomical
grounds. Dihnphus differs only from Mitroidea, Pease, by the
absence of plaits. The soft parts of the animal were first described
by Mr. A. Garrett,^ who was unable to detect any difference
between them and those of Cylmdra, Schumacher. Unfortunately,
it is not possible to ascertain the relationships of Teleochilus in the
same manner, as its soft parts are denied to us; on conchological
considerations alone it is included in Plettrotomid^, and may
be assigned a position in the neighbourhood of Daphnella.

Mr. Tenison -Wood's description of this species is as follows :
" Shell fusiform, thin, fragile, shining, whorls sis, gracefully
sloping, last longer than the spire, finely striate lengthwise with
irregular ridges of growth which become fine, close, and rounded
at the lip ; regularly and somewhat distantly grooved with rather
broad, flat, shallow, conspicuously striate grooves, one of which
is much broader just below the suture, which is distinctly
canaliculate ; apex obtuse and Natica-Wke ; mouth narrow, finely
rounded at the suture ; outer lip thin ; canal short, base of the
pillar finely and obliquely decussate behind."
The general characteristics of the protoconch have been alluded
to in the generic description. The figure of the species given
by its author is a representation of a much worn specimen ; it is
deemed advisable, therefore, to refigure it (Plate III. Figs, \2a-d).

central and the posterior plications, and some rugosities on the flat
portion of the callus in the umbilical region.
It has considerable affinities with the living C. semperiana,
Crosse, from New Caledonia, but the aperture of the latter is
much more dilated, the longitudinal costse are bolder, and the
shell as a whole not so solid.

This species is very different to any other Cancellaria from
Australasia in the British Museum. The shell is thin, cancellate,
sharply carinate, with a broad spiral platform at the suture ; the
spire in consequence is staged ; the protoconch is composed of one
and a half turns, the early portion of which is implanted obliquely
and is somewhat inflated, the remainder being decidedly convex
with deeply-cut suture ; aperture quadrately oval, outer border
crenulated, lirate within ; columella slightly callous, furnished
with three prominent plications.
CANCELLAEIA. 67
This is by no means a typical Cancellaria. M. Cossmann remarks
{op. cit. supra) that it should be classified with Bivetia ; but the
type of that subgenus has a posterior canal, varices, and other
characteristics absent in C. gradata. For the present it may
remain with Cancellaria proper, the present writer having no
inclination to increase the number of subgenera with which this
group is burdened.

This species is closely allied to C. capillata, but the longitudinal
costae are relatively larger and oblique ; columella with two
plications situated posteriorly. The specimen in the Museum
is not sufficiently well preserved to enable the protoconch, or
minute ornament, to be described. The general character of the

Professor Tate remarks that this is the antipodean analogue of
C. erulsa, Solander, from Barton, and that it differs "only by its
much finer ornament, and by the lirte within the outer lip." No
doubt there is a close I'esemblance between the two species, but a
study of the protoconch is sufficient to separate them immediately.
The Australian shell commences with a relatively large protoconch,
the earlier portion of which is obtuse and even slightly inflated,
and is composed of only one and a half turns ; the Bartonian .shell,
on the other hand, has a somewhat pyramidal protoconch com-
posed of from two and a half to three turns, the earlier portion is
not oblique, and the whole is regularly coiled. There must be some
error respecting the lirae alluded to : both the Australian and
European shells possess these within the outer lip, typical examples
of C, evulsa from Barton having them especially prominent opposite
the varices. The Australian shell is thinner.

Shell long, thick with sub-turreted spire ; protoconch obtuse,
composed of one and a half turns, the earlier portion being planted
obliquely with reference to the axis of the shell, smooth, except
anteriorly, where frequent, microscopic, longitudinal lineations
appear ; whorls deeply excavated at the suture, where an inward-
sloping spiral platform occurs ; spirally and longitudinally ribbed,
granulated at the points of intersection, the former being the more
prominent ; interrupted here and there by varices ; aperture
relatively small, ovate ; outer border plicate within ; columella
imperforate, with three plications ; anterior canal truncate.
This is a typical example of the subgenus Sveltia, except that
it has three columellar plications instead of two. In the young
these are even more marked than in the adult.

[non Morch).
A comparison of the soft parts of Olivella and Oliva exhibits
many features of interest, fully sustaining the generic separation
of the two. The head of Oliva, for instance, is furnished with
slender tentacles and eyes, the median tooth of its radula is
OLIVELIA. Yl
tricuspidate; on the other hand, a typical OUvella has neither
tentacles nor eyes, ami the median tooth of the radula carries a
great number of small denticles, in addition to which the radula
has accessory lateral plates. In spite of these important anatomical
differences, the shells of certain species of both genera closely
resemble each other, and it is, therefore, almost impossible to
classify them with any degree of accuracy from an examination
of the test alone. Fortunately, however, the more extreme forms
of the shells are not difficult to determine generically, and the
Australasian Tertiary fossils about to be described are allocated
to the genus OUvella without much doubt.
In general, the shells may externally be distinguished from
those of OUva by the columella not being plicate (or lirate)
throughout its entire length, whilst the columellar border is more
obliquely inclined with reference to the axis, and is sometimes
slightly excavated (as in 0. nymphalis, Tate) ; the spire is more
elevated, though this last character is by no means constant.

The spire in this species is long, in adult specimens being more
than one-third the entire length of the shell ; suture deep ; aper-
ture narrow, wider where the columella is slightly excavated;
plications variable in number, situated on the anterior half of the'
columellar border only.
Compared with 0. nitidula, Desh., of the Parisian Eocene, it is
found to be longer, its aperture is narrower and straighter, and
Its columella is less excavated ; in other respects it presents con-
siderable analogy with the shell of that species.

This is a more stunted form than 0. angustata, whilst the
plications are only two or three in number, being confined to
the anterior portion of the columella. The whorls have a tendency
to become invaginate, and the spiral sulcation near the middle
of the body-whorl is prominent.

Ancillaria, Lamarck, Ann. Mus. 1810, t. xvi. p. 302.
Sparella, Gray, Guide Moll. Brit. Mus. pt. 1, 1857, p. 26.
Shell oblong, occasionally acuminate ; suture sometimes canali-
culate, but more frequently covered over by callus ; columella
excavated, twisted, and carrying several plications anteriorly,
which are not hidden by callous growth, whereas the posterior
portion of the columella is thick, callous, or gibbose. A depression,
or groove, usually separates the callosity of the spire from what is
commonly termed the " smooth zone," though this zone is often
not as smooth as the callous spire, especially when strongly
exhibiting the lines of growth as in certain fossil species. The
73
relative size of this zone is of specific walue taken in conjunction
with cognate characters ; aperture grooved posteriorly, and truncate
and deeply sinuous in front.
Ancilla may bo distinguished from Olivancillaria, with which it
is frequently confounded, in that the latter, sensu stricto, has the
columella callous thi-oughout its entire length, the spire is usually
much more acuminate, and the sutures are deeply canaliculate.
The columella of the section Agaronia, however, is not callous,
except to a feeble extent posteriorly. Ancilla is readily dis-
tinguished from that subgenus, as the latter has such well-
developed sutures, and the comparative absence of callosity on
the spire and body-whoii is well marked.
The subgenus Sparella, almost universally adopted by modern
authors, must disappear in synonymy, for the following reasons : —
The type of Ancilla is A. cinnamomea, Lamarck, and the type
of Sparella is A. alhisuleala, Sby. ; but these two species are
synonymous with each other, the only distinguishing feature
between them being that the impressed groove of the latter is
white — a character without constancy. It is generally stated
that a more or less prominent denticle on the outer margin of the
aperture characterizes Sparella, but that is found also in the type
species of Ancilla ; the spread of the callosity over the spire is
usually regarded as a special feature, but what value that may
possess from a morphological point of view does not in any way
affect the synonymity of the type species mentioned.

This is the largest Australian Ancilla in the Museum. Professor
Tate compares it with the European Eocene A. luccinoides, Lamk.,
but it differs markedly from the latter : the broad band trespassing
anteriorly on the smooth zone of the body- whorl, terminating at
the inner margin of the aperture by a pronounced denticle forming
a slight postei'ior prolongation of the band, or of the groove which
borders it posteriorly, at once distinguishes this species from
74
A. huccmoides. The granulations on the callus, the manner in
which a portion of the latter is spread over the whorls of the
spire from the columellar border nearly to the protoconch, and
the relatively smaller size of the twisted anterior of the columella,
are also distinctive features.

This shell has an acuminate spire, the callus is not strongly
developed, and the sutures are bordered by a slight angulation
producing a spiral ridge on the surface. The smooth zone is rather
narrow, and the spiral band and denticle are well pronounced. It
presents some analogy with A . arenaria, Cossmann, from the Eocene
of the Paris basin ; the latter, however, is a smaller species, whilst
the aperture of the shell is not so large relatively, and its columella
is not excavated so deeply.

The callus of this species presents some analogy with that of
A. hehera, but the spire is contracted slightly at the apex; the
shell is not so cylindrical, and is much more elongated. None of
the specimens in the Museum exhibit the denticle ; its existence,
75
however, may be inferred from the feeble groove running round
the anterior portion of the body-whorl. The columella is exca-
vated, and for the size of the shell its plicated anterior extremity
is not very large. Professor Tate remarks that this species is
intermediate in character between A. hehera and Apseudaustralis.

This may be readily distinguished from all other Australian
Tertiary Ancillte by the peculiar aspect of the callous growth
around the spire, which is sculptured with narrow, sharply
rounded, spiral ridges of unequal size, the larger with two or
three smaller ones interposed. The spiral band, though deep,
is very narrow, and terminates with a sulcated denticle. The shell
is almost cylindrical.

Although differing in several important particulars, this species
is not unlike A. papillata. It lacks the solidity of the latter,
however, whilst the spire is not sculptured in the same manner,
the shell is not so cylindrical in shape, and the aperture is wider
and proportionately larger. Professor Tate compares it with
A. olivula, Lamarck, of the Paris basin, which it closely resembles,
though, as he remarks, the callosity is larger, more gibbous and
granulated in the Australasian fossil. The twisted anterior portion
of the columella is relatively much smaller than in the European
form.

The variable proportion of the callus on the spire, even in
specimens from the same locality, causes this shell to assume
a variety of forms. Sometimes it renders it mucronate, the callus
being finely granular and extending over the posterior half of the
columella, in which case it is impossible to observe the actual
shape and number of the whorls. In other specimens, owing
to the comparative absence of callus, the spire is almost acuminate,
the suture being distinctly cut in, but in any case the protoconch
is entirely covered up. The examples from Parimoa have the
greatest thickness of callus on the spire above the body-whorl,
and it is so disposed as to render the shell somewhat cylindrical
with an angulate ridge above the anterior suture. In the two
specimens from Glenelg river the callus is closely corrugated,
leading to the formation of a number of spiral ridges ; an accidental
mutilation of the spire of one of them reveals the protoconch,
which, as far as can be seen, is composed of two turns, the earlier
portion being very minute and the later somewhat inflated.
The denticle on the outer margin of the aperture is practically
a prolongation of a deeply-cut sulcus ; the anterior canal is broad
and deep ; columella excavated and carrying several small plications
anteriorly. In well-preserved specimens with but little callus,
what is commonly termed the " varnished zone " of the body-whorl
is light-brown in colour, in front of which is a band of the same
tint, but darker. The whorl is finely striated, both longitudinally
and spirally.
Compared with the older A. pseudaustralis, the latter is more
elongate, and its spire is more acuminate. Living examples of
the species are found in Australia, New Zealand, and Tasmania.
Some of the specimens of A. australis in the Museum very closely
78
resemble A. mucronata, Sowerby, and it is possible that the latter
is a local variation of the former.

Family HARPID^.
Genus HARPA, Lamarck.
[Mem. Soc. Hist. Nat. Paris, 1799, p. 71.]
Shell ovate, ventricose ; last whorl very large, ornamented with
regularly spaced longitudinal ribs, prolonged over the suture and
joined to preceding whorl; spire short; aperture wide, channelled
anteriorly, columellar border callous, the callosity extending over
part of the whorls, occasionally up to the protoconch ; columella
twisted.
Type. — Puccinum liar pa, Linnaeus.
Subgenus EOCITHARA, Fischer.
[Man. Conchy!. 1883, p. 601.]
Columellar callosity more sharply defined and elevated than in
Harpa [sensu stricto) ; posterior prolongations of the transverse ribs
frequently flattened against and practically covering the suture.
This, together with the subgenus Silia, Mayer, includes almost all
fossil forms of the genus.

pi. vi. fig. 2.
The protoconch of this species (Plate lY. Figs. 3«-J) is very
different to that of either S. siilcosa or H. tenuis, descriptions of
■which follow. It is more depressed than that of the type of the
genus, from which it differs also in being striated. It recalls
the protoconch of the Pliocene and living Valuta musica, Linn.,
though it is not quite as large. Compared with the protoconch
of specimens of H. mutiea, Lamk. (the subgeneric type), of the
Parisian Eocene, it is relatively much larger and is more depressed,
though of the same general character.
The ornamentation of the whorls consists of thin, elevated,
curved lamellae close together, the anterior portions of which are
twisted so as to obscure the suture ; between each of these
are three or four fine longitudinal lineations and many spiral stri«
closely set, the latter being continued up the posterior side of
the lamellae. The columellar border is covered with callus ; the
anterior portion, however, is comparatively free therefrom, being
sharply defined and elevated. The successive stages of growth of
the anterior canal have left a well-marked, broad, rounded ridge,
between which and the elevated columellar border is a deep
rugose sulcus.

It is noteworthy that the subgeneric distinction previously
observed should be emphasized also in the protoconchs of this
80
and its congener H. tenuis. The embryo of S. sulcosa has only
two and a half turns visible, the nucleus appears to be covered
over, and is slightly oblique, as exemplified by weathered speci-
mens ; the last turn is longitudinally lineated, the earlier portion
being smooth and shining.
This species is readily distinguished from any other Harpa of
the Australian Eocene by the flat area bordering the suture ; the
transverse lamellae are very close together, and are exceedingly
thin over the area alluded to. The columellar callosity is thin,
but sharply defined, with the formation of a deep sulcation and
perforation anteriorly.

The anterior of the protoconch (Plate IV. Eigs. Aa-l) is slightly
oblique, and almost entirely hidden by subsequent turns; there
are two and a half of these latter, and the whole are micro-
scopically granulated, the later turns being also transversely and
longitudinally lineated. This is a larger species than S. lamellifera,
and it has fewer longitudinal lamellae ; the interlamellar striae,
both longitudinal and transverse, are not so prominent, except
towards the anterior portion of the body-whorl, where a species
of corrugation results ; the shoulder of the last whorl is roughly
angulate, and this is accentuated by scaly projections from the
lamellfe in that region.
There seems to be a great deal in common between this and
H. puUigera, from the blue clays at Schnapper Point ; judging from
Professor Tate's figure {op. cit. pi. vi. fig. 9) it may, perhaps, be
regarded as an extreme form of this species.

Protoconeh (Plate IV. Figs. 5a-h) composed of two turns ; it
has the general features of that of H. tenuis, but differs in that
the initial portion is much inflated and is sharply defined from
the remainder. The anterior portion of the turns may be divided
into two parts, the earlier of which (like the first turn) is smooth,
and the later is obscurely ribbed. The last-mentioned character is
of much value in working out the phylogeny of the Gasteropoda ;
the more pronounced generic characters were imparted to the shell
whilst yet in the embryonic stage, prior to the escape of the
animal from the capsule. In the brephic stage the incised suture
is initially accompanied by an elevated border, which becomes
modified as the animal approaches the neanic stage, and altogether
disappears in the adult. The shell in the brephic stage also
has some rather bold spiral elevations on the whorl, which, in
conjunction with the closely-set longitudinal ribs, cause cancella-
tion, but this is wanting in the adult form.
A cursory examination might lead one to think that this species
was merely a variation of H. tenuis, with which it could not
possibly be confounded, however, when the protoconeh and shell
in the brephic stage are compared. The ordinary spire-whorls are
subangulated medially, and ornamented by rather distant, slightly
elevated lamellae.

Protoconch composed of a globose, obtuse, smooth turn, barely
distinguishable from the succeeding whorl. Shell small', elongate,
and polished ; spire moderately elevated ; whorls five in number
in adult specimens, convex, body-whorl obtusely angulate at the
periphery, surface longitudinally striated by lines of growth, and
obscurely spirally lineated, suture accompanied by an anterior
spiral depression ; aperture elongate, somewhat inflated towards

small crenulations terminated posteriorly by a rather large denticle,
or tubercle, behind which is a broad, slightly canaliculate depres-
sion ; inner margin with four prominent plications ; anterior
portion of the aperture widely channelled.
This species resembles M. contahulata, Deshayes, from the

This species is characterized by its broad aperture, which opens
out anteriorly and is deeply channelled ; the body-whorl is gibbose,
and well-preserved specimens exhibit inconspicuous, narrow, longi-
tudinal bands of brownish tint.
It differs from M. wentworthi in the characters above noted, as
well as by the absence of crenulations on the outer margin. The
latter in M. muscarioides is much thickened, especially towards
the middle, where an obscure denticle is observable in some
specimens ; the inner margin is somewhat callous, and carries
lour conspicuous plications. Professor Tate remarks that in a
broad sense this species is a diminutive M. muscaria, Lamarck,
from which, however, it differs, amongst other things, in that the
callous outer margin of the latter species is extended "on to
the penultimate whorl, thence spreading over the base of the
shell, and giving rise to a flattened appearance varicosely margined
on the left side." The sutural region in M. muscarioides is
somewhat depressed.
Mr. Dennant quotes this species as occurring in the younger
beds at Muddy Creek.

Shell elongate, subcylindrical, smooth ; protoconch obtuse, com-
posed of two smooth turns, the anterior being disproportionately
large ; spire elevated, three-whorled, body-whorl comprehensive,
ornamented by longitudinal curved growth-lines, suture con-
spicuous ; aperture elongate, tapering posteriorly, the sinus being
very small, broad anteriorly, and channelled ; outer margin
moderately thickened, but variable in individuals, closely crenu-
lated within ; columella callous, especially towards the anterior,
where five plications occur in the adult : these latter are close
together, and only four are well developed, the fifth one,
posteriorly, being very small, and altogether absent in young
specimens.
This is by no means a typical Marginella, but it does not fall
conveniently into any of the recognized sections of the genus.
The writer does not, however, feel inclined to add to these latter,
already too numerous for systematic purposes. It differs from
Marginella {sensu stricto) in its cylindrical shape and exsert spire,
and by the possession in the adult of five columellar plaits. It
has certain affinities with Volvarina, Hinds, ^ which, however,
has only four plications on the columella, whilst its outer
margin is not crenulated, at least in the type species, M. avena,
Valenciennes.
Specifically it closely resembles the living M. gracilis,
C. B. Adams {=z M. hibalteata. Reeve), from the "West Indies,
which is much smaller, more lanceolate, and is only quadriplicate.

This species differs from M. winteri in being broader, and in
having a much shorter spire. In studying the stages of growth,
which are illustrated by an excellent series of specimens in the
Museum, the following particulars concerning the columellar
plications may be noted. In the neanic stage of some individuals
four equal-sized, well-developed plaits occur, whilst in others the
two posterior plaits are much smaller than the anterior. As the
ephebic stage is attained a fifth, posterior plication appears, which
is placed farther within the aperture of the shell, and is very
small. In many individuals, however, only four plaits occur,
even towards the gerontic stage, and one specimen in the collection
possesses three large anterior plaits and one very small posterior.
Another point of interest is the development of the crenulations
on the outer margin. In the majority of specimens these are
found from the neanic stage onwards ; but it is clear from others
that crenulations were not developed, even up to the early portion
of the ephebic stage, although the thickening of the outer margin
took place under both conditions.
The foregoing observations, in the opinion of the writer, are
calculated to shed some light on the systematic value of the colu-
mellar plications and the crenulations on the outer margin, in this
group. It is customary with authors, dealing with Marginella,
to lay especial stress on both these characters, in assigning species
to subordinate divisions of the genus. Yet in M. propinqua
these features are very unstable, and certainly ought not to
rank higher than ontogenetic characters. Some authors might
be disposed to create another specific name for the non-creuulate
forms; but in carefully examining a series of the shells, it is

impossible not to recognize the phenomena alluded to as mere
variations of individuals of one species. The protoconch, the
shape of the shell, form of aperture, the suture — in fact, every
other characteristic except the number of plications and the
occurrence of marginal crenulations — are identical in the forms
here retained in M. propinqua.

Shell pyriform, attenuating anteriorly, smooth ; spire very short,

extending almost the whole length of the shell, longitudinal growth-
lines conspicuous, suture well defined, polished ; aperture elongate,
broadly rounded posteriorly and slightly produced anteriorly where
it is widely channelled ; outer margin thickened and crenulated,
though comparatively smooth towards the posterior extremity ;
columellar margin furnished with four plications in the majority
of individuals, though one adult specimen in the Museum has
only three, and another three with the trace of a fourth.
Its shape, the elongation of the aperture, and its rounded form
in the neighbourhood of the posterior sinus, serve to readily
distinguish 21. inermis from all other Australasian Marginella!,
Except for the dentated outer margin, this species might perhaps
be included in the subgenus Prunum.

Subgenus GLABELLA, Swainson.
[Malacology, 1840, p. 324.]
The principal distinguishing features of this subgenus are the
more or less conical form of the spire, which is well developed,
and the longitudinal plaits on the peripheral subangulation of the
body-whorl present in the majority of the species. The first
species mentioned by Swainson is quoted as "P. ruffina, Sw." ;
as it is not clear what he intended by that specific name,
M. hifasciata, Lamarck (one of the typical species mentioned
by Swainson), is here adopted as the type of this subgenus.
In reference to M. ovata and M. cornea, two new species here
described from the Tertiary of New Zealand, it may be noted tliat
certain kinds of Marginella have been recognized in the newer
beds of that colony ; but for the most part these have neither been
figured nor described, unless, indeed, two or three lines of
remarks can be called a description. The present writer has not
been able to identify either of the species above mentioned
with the meagre descriptions alluded to, and is of opinion that
these latter ought to be suppressed as being of no real value to
systematists.

This is unlike any other species of Australasian Marginella. The
spiral limb or callosity on the anterior of the columella, which
passes underneath another growth of callus on the inner margin,
is very distinctive, and is one of the reasons why the species is
here classified with Cryptospira. The number of plications on the
columella and the hidden spire are also specially characteristic.
Although not a typical Cryptospira, it is more closely allied to
that than to Persieula, which, typically, has an enormous callous

Family YOLUTID-Sl.
The fine collection of larval shells appertaining to this family
in the Museum collection of Australasian Tertiary moUusca,
suggests a few words concerning the origin and evolution of the
groups they represent, as deduced from the study of the proto-
conch, and early stages of growth of the shell generally.
The striking characters presented by the protoconch in living
forms of the family have long attracted attention, and were to
a limited extent taken advantage of in describing genera and
species. Amongst others who place a high value on the larval
shells for systematic purposes is M. Crosse, of Paris, who reviewed'
the living species referred to the family, and was willing to
concede, in at least one instance,^ that the phenomena of the
protoconch might be of generic importance. Eut it was reserved
for Professor W. H. Dall,' of "Washington, who studied fossil as
Avell as living representatives of the Voltjtid^ to throw the
greatest light on this matter. He stated his conviction that the
family descended from the Mesozoic " Fusing. " In the Mesozoic
transition forms the larval covering was shelly and minute, its
upper surface like a minute Co7iulus or Hyalinia. This indicates,
he believes, that those forms found their benefit in the production
of a large number of small shell-bearing larvae, rather than in
a small number of large ones. This holds good for all the
Mesozoic forms, at least in America, and for all the exotic

Mesozoic forms he has been able to examine. These small larval
shells are persistent, and often of a different texture to the
succeeding whorls of the adult. Professor Dall remarks' that
" "When the Volutid^ first begin to appear, and branch off from
Fusus, Fasciolaria, and Turhinella, the nucleus or larval shell in
all these forms was small and shelly "W"e may classify the
larval shells broadly into two groups — those which were shelly
from the beginning ; and those which have succeeded to a horny
or uncalcified protoconch, which is lost before the larval shell
escapes from its ovicapsule There are several forms of the
shelly nucleus. It undoubtedly preceded the horny one in this
group."
This is followed up by dividing the larval shells into two
groups — (1) the Volutoid series, and (2) the Scaphelloid series.
Representatives of both these groups occur amongst the Austra-
lasian Volutes presently to be described.
The Volutoid Series. — This series is characterized by the
possession of a shelly protoconch, the earliest form of which is
called the " trochiform," and is met with in Liopeplum of Upper
Cretaceous age, aud in the earlier types of Volutilithes. This
kind of protoconch is practically identical with that of the
original stock from which those genera sprang. A variation
from this, in which the earlier portion becomes flat, is termed
" planorboid " ; another, where the turns of the protoconch are
more numerous and are considerably elevated, is known as
"pupifoi-m"; whilst another important step is taken when the
larval shell becomes larger, one-sided, and much inflated, as in
the type known as "bulbous." Finally, as a more recent develop-
ment in the Volutoid series, there is the enormous protoconch
in which the "trochiform" type has become greatly exaggerated
— known as the " melo " type.
Turning to the Australasian species here catalogued, the writer
recognizes amongst the Volutoid series, representatives of Voluti-
lithes, Lijria, Fterospira (a new subgenus), Aulica, Volutoconus,
and Amoria.
The protoconch of the Volutilithes represented, is not of the most
archaic type ; it is a modification in which the small trochoid
1 Trans. "Wagner Free Inst. Sci. Philad. vol. iii. 1890, p. C6.
94
original has given way to a small inflated, asymmetrical form
(see Plate IV. Figs. 8a-b). Neither Volutilithes antiscalaris nor
V. anticingulakis can therefore be said to be examples of the real
stock of the genus, which was of greater geological antiquity
than they. This is important in view of the habit of modern
palaeontologists to link the Australian species mentioned too closely
to such typical European forms as V. scalaris and V. spinosus,
from a consideration of the sculpture of the whorls and the character
of the columellar plaits alone. It is quite a question whether
the antipodean forms alluded to ought not, indeed, on the evidence
afforded by the protoconchs, to be separated from Volutilithes
{sensu stricto) and placed in a new subgenus.
In regard to Lyria^ but little need be said ; the larval shells
(Plate IV. rigs, 'da-h) and adults are very similar to European Eocene
types, and they do not differ materially from living representatives
found in the Indian and Pacific oceans, China seas, etc. The
genus appears to have separated from the Jiostellites- Volutilithes
stock in the Cretaceous. In common with the remainder of the
VoLUTiDiE in existence in the early Eocene, it was then in a very
unstable condition, as witness the variable character (within limits)
of the protoconch of Lyria harpula, Lamarck, from the Calcaire
Grossier of the Paris Basin. After having provided Fulgoraria with
its small bulbous protoconch (to be afterwards greatly enlarged as
in the living V. npestris, Gmelin), it seems to have settled down,
and to have come on from late Eocene times to the present day
without material modification. It succeeded, however, amongst
other things, in giving rise to Valuta {sensu stricto) during the late
Miocene or early Pliocene ; and the living Enata was separated
from it in the post-Pliocene.
The only Pteronpira here recorded has a Fulgoraria^^ik& bulbous
protoconch (Plate IV. Eigs. lOa-5), and the subgenus was probably
intimately connected with Fulgoraria, which is not represented in
the collection.
In reference to Aulica, so little is known concerning its geological
histoiy, and the material for studying it in the fossil state is so
limited, that it is impossible for one to say definitely by which line
of descent it came from the early Volutilithes stock — whether
along that of Volutilithes proper, or through the medium of Lyria.
The Australian Tertiary Voluta strophodon and V. weldi, very
characteristic forms^ appear to be the precursors of the modern
VOLUTIDJE. 93
species of Vespertilio, as well as of Aulica, and they are in
a measure liaked together by the Tertiary Valuta macdonaldi, as
■\viU be seen later on (see p. 106). There is nothing antagonistic
in the view that the protoconch (Plato IV. Figs. Wor-b) of either
of the antipodean species mentioned is a gigantic representation of
Volutilithes far advanced in an evolutionary sense. Neither, on the
other hand, can it be denied that there is much in common between
it and typical examples of Valuta (as in the living V. musica,
Linnaeus). The spinose character of the whorls in V. stropliodon
and its congener — if such a property can be said to be of any value
whatever for systematic purposes — certainly reminds one of true
Volutilithes also. In the present state of our knowledge, however,
the writer prefers to leave the mode of descent of Aulica an open
question ; though the latter undoubtedly came from the Rostellites-
Volutilitliss stock, and was evolved in late Eocene, or more
probably in Oligocene, times.
The corrugations of the anterior part of the protoconch of
Volutoconus (Plate IV. Figs. 13<j-5) suggest affinities with Vespertilio
(see p. 108) ; and the larval shell as a whole, at least in the fossil
Valuta conoidea, betrays its origin in Aulica, of which Vohctoconus
may be regarded as a minor but persistent offshoot.
Amoria has a more pointed protoconch (Plate IV. Figs. 14«-5)
than Aulica, and the anterior portion is more spread out; but
it is obviously a modification of the Valuta strophadon type of
larval shell, of late Tertiary origin. By the general con-
figuration of the shell of the adult, both in fossil and living
forms, Amoria appears to be sharply defined from all other groups
of the VoLUTiDiE. It has been a characteristic of the Australian
fauna since Upper Miocene times, if the upper beds at Muddy
Creek are as old as that period.
The Scaphelloid Series. — In typical forms of this series the
larva is clothed with a horny protoconch, the existence of which
was first made known by Professor Dall,' with reference to the
living Scaphella magellanica, Sowerby. That author remarks that
the horny type was probably similar in form to that which, when
shelly, results in the "bulbous nucleus" of the Volutoid line of
descent. " Later on," he says, " but while still in the ovicapsule,
' Bull. Museum Cornp. Zool. llarvard, vol. xviii. 1889, p. -45:;
V0LCTID2E.
the deposition of limy matter begins as a slender cone or elevated
point along the line of the axis of the protoconch, and as the
larva grows the posterior part of the mantle secretes a shelly
dome. Being thus cut off from the horny protoconch, the
latter falls into shreds, and is lost. The nucleus of the larva,
still in the ovicapsule, then presents a slightly irregular dome,
with a slender point rising from the apical part." The horny
portion is never found in the fossil state ; but its former presence,
where it existed, may be inferred from the scars and irregular,
often granulated, aspect of the shelly portion of the protoconch
which remains. In those cases where the shell has been rolled,
or (with reference to examples of living Volutes) where it has
been treated by acid to "clean" it, as with large numbers of
shells in our museums, it is often impossible to detect the
Scaphelloid type of protoconch, and thus to assign species to
their proper systematic position in the VoLUTiDiE.
Without going into details, it may be observed that Professor
Dall has detected three types of Scaphelloid protoconch. Those
in which it is pointed he calls the " CaricelW type; the larger
and pointless kind is termed the ^^ Scaphella^^ type; and the
dome-shaped form is named the " Cyniba " type. That nomen-
clature, as well as the terms employed in reference to the Volutoid
series, is here adopted.
The Scaphella type is represented in the Museum collection by
several species, of which 8. polita (Plate IV. Figs. Iba-h) is a
good example; and the Caricella type (Plate IV. Figs. 16«-J) is
well illustrated by a number of species of Eopsephia (see p. 115).
This is not the place to discuss the geological age of the beds in
which the bulk of the Volutes occur ; in deference to the authority
of Professor Tate such beds, as at Muddy Creek, Schnapper Point,
Cape Otway, etc., are here termed "Eocene." But the writer
cannot help remarking that the development of the larval shells
of the family now under discussion, in the majority of instances,
in such specimens as occur in the beds at the localities mentioned
(excluding the upper beds at Muddy Creek), is much more
advanced than one would have expected to find in beds as old
as the Eocene — that is, on comparison with what is found in the
true Eocene in other parts of the world.
TOLUTILITHES. 97
Genus VOLUTILITHES, Swainson.
[Malacology, 1840, p. 318,]
Shell fusiform ; spire conical ; protoconch small, rising to a more
or less acute apex ; whorls costate, typically spinose ; columellar
plications variable, several in number, those towards the anterior
generally being the most pronounced.
The special character of the protoconch, and the peculiar dis-
position of the columellar plications, are highly distinctive features.

1889. Voluta antiscalaris, Tate, Trans. Roy. Soc. South Aust. vol. xi. p. 133.
This species somewhat resembles V. scalaris, Sowerby, from
Barton, in Hampshire ; but, as Sir F. M'Coy points out, it may
be distinguished by its slightly longer spire, less ventricose body-
whorl, and the costae are less twisted. The protoconch (Plate lY.
Figs. %a-b) also in the Australian species is more obtuse, consisting
of one and a half smooth, rounded turns. The columellar pHcations
are remarkable ; in the neanic stage they are commonly from three
to four in number, but in the adult they range from six to twelve,
and possibly more. In the ephebic and gerontic stages the whole
of the plications are mounted on an elevated callosity. The
anterior portion of the columella is slightly excavated, a feature
especially noticeable in adult specimens.
Compared with V. dejmuperatus, Sowerby, of the European
Upper Eocene, with which it presents considerable analogy, it is
found to possess a relatively longer aperture and a more obtuse
protoconch.

This differs from V. antiscalaris in not being so spinose, its spire
is moi-e elevated, and the comparatively obscure longitudinal ribs
on the body- whorl are furnished with obtuse tuberculations forming
a rough angulation on the shoulder, though the ribs are more
pronounced in young specimens. The aperture is wider, and the
outer margin not so thick as in the other Australian species
alluded to ; columellar plications generally fewer in number.

Shell ovate ; protoconch small, from one and a half to two

anterior channel broad; columella with several plications, two in
front being much compressed and very large, the others decreasing
in size antero-posteriorly ; outer margin thickened.

The disposition of the columellar plications and the strongly

The protoconch of this species (Plate IV. Tigs. %a-V) is
practically identical with that of Lyria harpula, Lamarck, of the
Eocene of Europe. The shell as a whole, however, is larger,
more volutiform, and the transverse costse are more numerous.
The latter terminate posteriorly in obtuse points leading to a
flattening in the vicinity of the suture ; spiral lines prominent
on the body-whorl anteriorly. The outer margin of the aperture
is not very thick ; whilst the columellar border is furnished
towards the anterior canal with two plications more prominent
than the remainder, which become very minute as they gradually
disappear within the aperture posteriorly.

Shell solid, broad, longitudinally plicate, the plications being
elevated into obtuse tubercles on the periphery of the whorls ;
spire short ; protoconch elevated, turbinate, smooth ; aperture
narrow, canaliculate behind and broad in front ; inner mar"uu
often covered by thin callus ; columella carrying many plaits,
four or five being prominent, the remainder much smaller.
Type. — Voluta musica, Linnteus.
100
Subgenus PTEROSPIRA,' nov. subgen.
Shell broadly fusiform; protoconch bulbous, granular, much
larger than succeeding whorls, initial portion lateral and hidden ;
whorls spirally striated, tuberculose at the periphery, body-whorl
very large, outer margin in adults forming a wing-like expansion,
with a broadly rounded, auriculate posterior margin, rising nearly
up to the suture of the penultimate whorl for attachment; inner
margin covered by a thin deposit of callus; columella excavated
in the middle and furnished with three large, equal, prominent
plications.
The wing-like expansion of the outer margin of the aperture
and the enormous globose protoconch serve to distinguish Pterospira
from all other groups of the A^olutid^. The general character
of the larval shell is that of Fulgoraria, as typified by Valuta
rupestris, Gmelin.

Distinguished by its immense, inflated protoconch (Plate IV.
rigs. lOa-i), and the wing-like expansion of the outer margin
of the aperture. The whorls are obtusely angulate, crowned by
nodose tubercles, which near the summit appear as rugose costae.
In the young of this species the last whorl is spirally liueate, the
lines being close together in the neighbourhood of the suture and
towards the anterior portion of the columella, and more distant
between those two points ; in the adult the anterior part of the
whorl is smooth ; the columella has three plications.
It differs from its congeners V. macraptera, M'Coy, and
V. mortani, Tate, in that the whorls of the latter are practically
smooth, though all possess the wing-like expansion. The present
writer is unable to speak as to the precise character of the

Shell oval - oblong, more or less ventricose ; protoconch
regularly coiled, turbinate or trochoid, elevated, smooth or
obscurely lineated ; whorls of the spire smooth, spinose at the
periphery, the nodulations being distant and situated on broad,
short costse in the adult ; columellar plications commonly four
in number.
This is very closely related to the subgenus Vespertilio, Klein
{em.), the principal differentiating character being the protoconch,
which in Aulica is, typically, smooth, whilst in Vespertilio it is
crenulated. The fossil forms here described appear to be the
common ancestors of the living forms of the two subgenera
mentioned, and in general shape they approach also the earlier
(stock) Volutilithes, from which they differ, however, very
markedly in the characters of the larval shells.

Considerable analogy exists between this species and certain
well-known forms of Volutilithes ; the protoconch is the chief dis-
tinguishing feature. The form of V. stropliodon varies considerably :
102 TOLUTA.
some specimens have a spire approaching that of V. sj^inosus,
Lamarck, of the European Eocene, as remarked by Sir F. M'Coy ;
■whilst others are conoidal and have been compared with V. athletus,
Solander. A strong variety of V. athletus (perhaps a distinct
species) found in the Sables Moyens (Upper Eocene) of Le Ruel,
Paris Basin, which more nearly approaches the typical V. spinosus,
is not unlike the Australian species now diagnosed ; but the latter
has not much in common with the typical V. athletus found at
Barton, in Hampshire, which has a more depressed (and not conical)
spire with enormous, obtuse spines. The columellar plaits of
V. strojjJiodon are four in number, sharp, of approximately equal
size, and oblique ; the first one anteriorly being directed so as
to merge into the fiat callosity bordering the deep, broad canal.
The disposition of these plaits alone suffices to distinguish it from
the European Eocene forms alluded to, which have one large
anterior plait or fold, with several smaller ones behind it.
Certain forms of this variable species so closely resemble
V. symmetricus, Conrad, of the Eocene of Jackson, Mississippi, that
they are not easily separated from it at first sight. An examination
of the protoconch (Plate IV. Figs. Wa-h), however, soon places all
doubt at rest : this Australian species has a large, obtuse, turbinate,
spirally striated protoconch, whilst the European and American
species mentioned all have the sharp, small protoconch so charac-
teristic of Volutilithes.

The present writer is almost inclined to regard this as a
variation of V. sirophodon (or vice versa) brought about by the
extremely favourable conditions under which it lived. It has
a thicker shell, the callus spread over the columella extends some
distance beyond on to the body-whorl, from which it is sharply
defined ; the costa? are almost obsolete, but each has a pronounced
pointed tubercle at the subangulate periphery of the whorls. One
specimen in the Museum has five columellar plaits — four normal
and one subsidiary, the latter becoming developed as the gerontic
stage was attained.

Shell fusiform, elongate; protoconch large, turbinate, or trochoid,
composed of three and a half turns, inconspicuously spirally lineate
and, anteriorly, longitudinally striated ; whorls of the spire concave
posteriorly in the neighbourhood of the suture, and convex towards
the middle, ornamented by undulating, unequal, closely-set liras
accentuated at the periphery, and absent on the anterior half of
the body- whorl in the adult ; aperture elongately oval, contracted
behind and broad in front; columella curved towards the middle,
furnished with four well-developed oblique plications.
Special attention may be directed to the vestiges of coloration,
which do not appear to have been previously described in this
species. As will be seen on reference to the figure now given
104
(Plate IV. Fig. 12), they consist of closely-set zigzag lines
somewhat similar in character to those of the living V. undulata.
They are preserved in conseL^uence of those portions of the shell
where they are found being more durable than the remainder of
the surface ; the markings are slightly in relief.
This species is assigned to the subgenus Aulica because the
protoconch is identical with that of the other Australian forms
here included therein, and agrees very closely with that of the
type species. The general shape of the shell is more suggestive
of Scaphella, however. It is minus tubercles, or spines, and
lacks the solidity of V. aulica. In some respects it resembles
V. bednalli. Brazier, living in North Australian seas.
The writer has not seen an authenticated specimen of V. lirata
as described (but not well figured) by Mr. E. M. Johnston ; but
accepts Professor Tate's interpretation of the species. It may
be pointed out, however, that Mr. Johnston describes the
"puUus" of his species as having only one and a half turns,
whilst the species as here accepted possesses three and a half.
In all other respects the Muddy Creek examples appear to corre-
spond with his description.

Shell somewhat fusiform, narrow, thin ; whorls slightly convex

little elevated on the periphery, but becoming almost obsolete
105
anteriorly, where they are mingled with the numerous longi-
tudinal strios more pronounced on that part of the shell ; columella

Professor Tate remarks that this is intermediate between
V. lirata and (what is here called) Scaphella sarissa, though
differing from the latter by its "puUus" and the absence of
pronounced spiral sculpture. So far as general form is concerned,
that observation may be endorsed ; but, if close genetic relationship
with >Si. sarissa be implied, that view must be dissented from,
as the species arose from another line of development in the
VoLUTiDiE, There can be no question, however, of its immediate
connection with V. lirata, from which it differs in shape and
by the well-developed costae.

The only example in the Museum is a young specimen, well
preserved, and exhibiting the characters of the elevated trochoid
protoconch and brephic and neanic stages to perfection. From
this it may be gleaned that the ornauient first to appear, and
just prior to the escape of the animal from its capsule, was the
longitudinal ribbing; the ribs are small and close together, and,
with the growth of the shell, gradually develop into fine longi-
tudinal striae. In the brephic stage, bold spiral lineations make
their appearance, and these persist to the neanic stage ; at the
same rate of progression they should, however, become almost
obsolete in the adult. The suture is slightly incised, and the
whorls are somewhat constricted posteriorly in its vicinity. The
columella is slightly callous, and has four distinct plaits.
The protoconch is very similar to that of V. lirata and
106
V. pseudoUrata ; but the shell differs from them in being devoid
of longitudinal costas and by the development of the spiral striae
alluded to.

three, excluding pullus; the two posterior whorls angulated in the
posterior third, the front parallel with the axis and costated, the
posterior area concavely sloping upwards; the costae terminate at
the shoulder in high- vaulted spinous scales ; on the first spire-
whorl the spines are about twenty in number, and terminate each
a pair of costse. The body-whorl is somewhat ventricose, with
a high shoulder, concavely sloping upwards to the suture ; the
angulation crowned with sixteen spinous scales, which terminate
broad undulations, not ribs, rapidly becoming obsolete. Columella
with four distant plaits . . . whole surface [of shell] is sculptured
with striae and growth-lines ; the only spiral sculpture is confined
to the last whorl of the pullus. The pullus is not sharply separated
from the ordinary spire-whorls, as there is a gradual change in
the shape and ornament of the whorls ; the actual junction being
somewhat indicated by a slight eccentricity of the first spire-
whorls."
The depression of the initial portion of the protoconch is not
a point of much systematic value, and the species is here included
in Aulica, though it is by no means a typical example of that
subgenus, on account of the general agreement of the earlier patt
of the larval shell with certain forms of Aulica. The first three
107
or four whorls taken together remind one of Vespertilio, except
that the protoconch is not lirate or tuberculate at the commeuce-
nient. The larval characters indicate the influence of both of those
branches of the Volutidjs, and it appears to lie in an intermediate
position between them.
In general form, except that the whorls of the spire are more
elevated, V. macdonaldi is somewhat like the living V. rossinimia,
Bernardi, of New Caledonia, a close ally of V. imperialis, Lamarck,
of the seas in the neighbourhood of the Philippine Islands. The
protoconch in the fossil species, however, is much larger,

Shell oblong, subcylindrical ; spire short and obtuse ; protoconch
broad, depressed, planorboid ; whorls ornamented by minute,
closely-set spiral lineations crossed by rather conspicuous growth-
lines ; outer margin of the aperture simple, slightly reflected
towards the midtUe ; columella with four plications, not well

Protoconch (Plate IV, Figs. 13a- J) broad, depressed, composed
of three turns, the earliest being exceedingly small in comparison
with the others, the whole being bordered at the periphery next
the caualiculated sutui-e by an elevated ridge ; last turn irregularly
108
spirally cornigatecl. It is difficult to define, from the specimen
in the Museum, the exact limits between the protoconch and
the shell in the brephic stage, but approximately at the junction
between the two the larval shell is longitudinally corrugated,
which suggests analogy with Vespertilio. The whorls of the spiie
proper envelop the suture, the junction being uneven ; they are
sculptured with delicate, undulating, irregular growth-lineations,
crossed by faintly discernible spiral strife ; body- whorl obscurely
tuberculose at the periphery, the broad nodulations being far
apart, and (judging from the figure given by Professor Tate ^)
more conspicuous in some specimens than in others. Outer
margin of the aperture sharp, slightly inflected medially, inner
border with four sharp, oblique plaits on the anterior half of the
columella.
This species is narrower and more coniform than either

longitudinal lineations ; suture callous ; columella with four or
five plications.
This subgenus is confined, in the living state, to Australasia,
and it is interesting to note the occurrence of fossil forms. The
coloured lineations are persistent, even in many fossil examples —

Shell fusiform, ovate, smooth; protoeorich (Plate IV. Tigs, \ia-l)
turbinate, pointed, the anterior portion being larger than the

closely-set, thin, undulating, chestnut - coloured lines — a very
distinctive feature.
Compared with the living V. undulata, of which it appears to
be a direct ancestor, the body-whorl is more rounded and inflated
at the periphery, the posterior channel is deeper, and the coloured
lineations are of a widely different pattern. It somewhat
resembles the living V. zebra, Leach, from which, however, it

SCAPHELLA. Ill
There seems to have been some difficulty in deciding what
should be the type species of Scaphella. On reviewing the subject,
Professor DalP emends the genus and selects S. undulata, Lamarck ;
that species, however, clearly falls in Anioria, Gray,- and is not,
therefore, available for a typical Scaphella. In a subsequent work
Professor Dall ' quotes Valuta junonia, Hwass, as the type, which
species was included by Swainson in his genus, and that view
is accepted in this work.

This, and S. polita are very distinctive species, differing from
all other Australian members of the family here described in
being smooth and polished, and in possessing true Scaphelloid
protoconchs. S. maccoyi has a thin shell, minutely striated by
lines of growth and flatly depressed near the suture ; columellar
plications four in number in the brephic and neanic stages, but
frequently five in the ephebic, due to the development of a small
plication posteriorly ; the plications are more oblique in the young
than in the adult forms ; outer margin thickened and reflected
outwardly.

This is a close ally of S. maccoyi, from which it differs only in.
being proportionately broader, in having more ventricose whorls,
and by the protoconch being larger ; columellar plications typically
five, but sometimes six in number, the largest plait being placed
anteriorly.
The protoconch (Plate IV. Figs, \5a-h) in general shape is
turbinate, and is distinctly scaphelloid. It consists of two turns,
the earlier portion of which is irregularly granular, and rises to an
obtuse point, the later portion being regular, deeply canaliculate,
and spirally and longitudinally lineate anteriorly.

Spire composed of four slightly convex whorls ; in the young
stage these are obliquely ridged and furnished with spiral
lineations, both of which characters almost disappear as the
ephebic stage is attained. Body-whorl in the adult closely longi-
tudinally striated, and with obscure spiral lines ; suture incised ;
aperture large, contracted posteriorly, expanded anteriorly where
it is truncated and broadly channelled ; outer margin thick and
slightly sinuous, inner margin covered by effuse polished callus ;
columella with three plications which in the young are much
113
compressed, very thin, and more oblique than in the adult. A
very noticeable feature in the shell is the arch-shaped, much
produced columella.
It is unfortunate that the only specimen in. the Museum is
minus its protoconch ; and the present writer is not able, in
consequence, to assign the species to a systematic position without
doubt. From Professor Tate's description, and from the figure
accompanying it, the protoconch would appear to be bulbous,
which is not a characteristic of Scaphella. It is possible, on
that account, that the species should be assigned to Voluta,
and placed somewhere in the neighbourhood of Fulgoraria,
Schumacher ' ; but the other features of the shell are in close
agreement with the genus in which it is here placed, and in the
absence of direct evidence it may be provisionally retained as
a Scaphella.

or three of which are plicatecl, the plications dying out as the adult
stage is attained. Pari passu with this phenomenon we find
in some individuals the incoming of tubercles at the periphery
of the whorls ; these are distantly situated, small at first and then,
becoming very large, the maximum size being reached with full
growth of the shell. On the other hand, we find individuals
in which these tubercles are not developed ; after the plications
on the earlier whorls had died out the remainder of the whorls
became perfectly smooth, as may be seen in examples of the species
in the living state. Clothed with prominent, spinose tubercles,
this species bears but little resemblance to typical forms of the
genus Scaphella; but when smooth it is readily comparable with
S. junonia. The last-mentioned characteristic, taken together with
its distinctly scaphelloid protoconch, enables the writer to assign
it to Scaphella, and it may be placed in the neighbourhood of
JEopsephia. The outer margin of the aperture is thin and reflected
outwardly ; columella covered over by a thin deposit of callus,
plications to the number of four.

This is a close ally of S. 2^acijica, of -wliicli it has been regarded

Subgenus EOPSEPHIA, Fischer {em.).
[Manuel Conchyl. 1883, p. 607.]
Shell long, fusiform ; ornamented by longitudinal ribs commonly

has seven plications, the anterior being the more salient. So far,
it agrees in general with the subgenus Pseph^a, Crosse ' (type
Voluta concinna, Broderip) ; but the protoconch is very distinctive.
The latter is of the '^csqiheWoiA-Caricella type, somewhat inflated
and rising to a sharp point, laterally situated.
The Australian species here included in this subgenus differ
from typical forms of Eopsephia in regard to the number and
disposition of the columellar plications, and the shells as a whole

are more elongate. Possibly they are entitled to rank as a separate
subgeneric group ; but the characters of the protoconchs present
no serious diiferences from those of true Eopse/phia as found in
the Eocene of the Paris Basin, and the phenomena connected with
the columellar plications do not seem important enough to warrant
even subgeneric separation.

Protoconch (Plate IV. Pigs. 16a-b) composed of three turns,
the earliest being small, somewhat granular, and rising to a sharp
point in well-preserved specimens, later turns larger, flat, with
a bordered and deeply canaliculate suture, anterior portion spirally
lineate and longitudinally corrugated. Shell fusiform, turreted ;
whorls flatly convex, ornamented with spiral threads and angular
costpe, described by Professor Tate as follows: — "The rounded
spiral threads (about twelve on the first whorl), which are about
as Avide as the interspaces, increase in number with the revolution
of the spire. On the fourth and fifth whorls, adjacent to the
anterior suture, the threads are reduced to striae ; and on the
body-whorl the anterior half is smooth, or nearly so. The costse
begin to appear on the front half of the second posterior whorl,
and on the three anterior whorls have attained to stoutish, wedge-
shaped, slightly curved, angular ridges, which are continued in
subdued strength to the anterior sutxu'e, but do not reach the
posterior one. Last whorl with about nine transversely elongate
costte on the periphery, not much attenuated to the broadish open
canal, which is bent to the right and slightly reverted." The
columella carries five large, somewhat flattened plaits, the first
and fifth being smallest ; between these are occasional obscure
folds, especially noticeable in adult specimens.

Protoconch similar to, but smaller than, that of S. sarissa,
though not perfect enough in the Museum specimens to enable
details to be given. The shell in the brephic stage is strongly
longitudinally ribbed. The aperture of this species is much
longer in proportion to the length of the shell than in that
species; the longitudinal costae are reduced to pointed tubercu-
lations on the shoulder, in front of which the last whorl is
depressed; longitudinal striae conspicuous, irregular, and undu-
lating. The author states that there are "four subequal,

more numerous and closely-set grooves ; aperture narrow,

Mitra multisulcata, sp. nov.
[Plate V. Figs, la-d.l
The protoconch of this species forms an interesting study ;
it is composed, typically, of six gradually increasing volutions,
polished, slightly granulated, and the anterior turns are longi-
tudinally striated. In the first two volutions the calcium carbonate
assumes a white, rather pearly colour and lustre, the succeeding
turns being light yellow and porcellaneous. The large number of
volutions indicate a long intracapsular existence. The protoconch
is clearly cut off from the shell proper. In some specimens ex-
amined there were only five volutions, and these were implanted
obliquely with reference to the axis of the shell. Immediately
the larval form escaped from the capsule it commenced to grow
vigorously, and at once assumed the cancellate structure so well
developed in succeeding whorls.
The formation of the columellar plaits at this (brephic) stage
may be described as follows : — Shortly after the shell emerged
from the capsule the anterior portion of the columella became
slightly callous, and this was prolonged posteriorly into an incon-
spicuous ridge, which, as the animal grew, developed into a true
columellar plication. That portion free from callus bears, even
at this early stage, two small plications, which must not be
confounded with the bold spiral liueations, seven in number,

121
wound round the pxllar. The posterior of these plications is
nominal y placed between the second and third (counting postero-
antenorly) hneations; whilst the anterior is practically conter-
minous with the fifth lineation.
At a later period of the brephic stage, when the normal shell
had developed to the extent of a whorl and a half, the whole
p.llar became covered with a slight deposit of callus, with three
plications the hindermost being decidedly the largest and the
anterior the smallest. At two and a half volutions the plications
became still more accentuated, though not increased in number
But between that period, and until five normal shell-whorls were
formed neanic stage), a fourth columellar plication was developed
anteriorly. Finally, with the production of seven normal whorls
-the most adult example of the species in the Museum-yet
another, the fifth, plication was formed.
From the foregoing it would appear, therefore, that the number
of columellar plaits in the brephic stage was only two and the
suspicion of a third, and that as the shell increased in size the
number of plaits increased also, until in the adult there were
no fewer than five of them. Whatever might be the true origin
and function of the plaits, we find, in this case at any rate, that
they were always developed anteriorly.
These facts ought effectually to dispose of the view that the
number of plications in such a genus as Mitra is per se of specific
importance It is quite clear that in many instances the number
developed depends on the stage of growth, and, when the animal
ot JUdra becomes senile, subsidiary plications are frequently
lormed between the normal plaits.
The ornament of the whorls of M. mxdlhulcata consists, essentially
of closely-set small sulcations running spirally, interrupted by
fairly equidistant, longitudinal striae or lines of growth, the whole
assuming a minutely cancellated aspect. This ornament extends
Irora the brephic stage, and persists with extreme regularity to the
senile, only that, in the more adult individuals, the growth-lines
are somewhat corrugated. The spiral sulcations are multiplied
•'s the shell increases in size, additional ones from the protoconch
onwards being developed between those already formed The
sulcations become much broader on the anterior aspect of the
body-whorl The sutures are very slightly cut iu, the whorls
oeing a little convex, and not angulate.
122
The aperture is rather more than one-third the length of the
■whole shell ; it is elongately ovate, outer border arcuate, smooth
within, acute at the suture posteriorly, broad and truncated
anteriorly. The margin of the aperture is oblique with reference
to the axis of the shell.
This species has hitherto been confounded apparently with
its congener M. alokiza, Tenison- Woods, fi*om which it differs,
however, in many important particulars. The protoconch of
M. muUisiilcata, as will have been noticed, is more fully developed ;
its spiral sulcations are much closer together from the earliest
stage ; the body- whorl is minus a subangulation, the margin of
the aperture is not parallel with the axis of the shell, and it
is wider and more arcuate ; finally, it is relatively more truncate
anteriorly.

This is distinguished from M. alohiza and M. multisulcata in that
its nine whorls are much more convex, and the columella has only
one, prominent plication, with the suspicion of a second. The]
surface of the shell is covered by almost imperceptible spiral striae,
which, however, become much more pronounced and developed
into prominent spiral ridges on the anterior half of the body-
whorl. The sutures are deeply cut in, and peculiar indentations,
where spots of colour appear to have been, border the whorls in
that region.
Professor Tate does not mention Muddy Creek as a locality for
this species, but the specimen in the Museum undoubtedly came
from there, and not from Schnapper Point. It is much larger, has
more whorls than the figured type, and is more perfect, though the
protoconch is wanting.

The heterogeneous forms usually included in this subgenus
sufficiently attest the absurdity of utilizing ornament of the whorls

The protoconch (Plate V. Pigs. 2a-b) in this species is large,
obtuse, and composed of four turns, the first three of which are
implanted obliquely, in the majority of individuals; its suture
is somewhat canaliculate, the surface of the shell being smooth
and polished, but the fourth turn is spirally lineate, the lineations
being in strict continuity with those, more plainly marked, on
the whorls in the brephic stage.
The shell as a whole is somewhat fusiform, with a rather
elevated spire of five convex whorls ; spiral ridges conspicuous
and regular, crossed by sinuous growth-lines. Aperture half
the length of the shell, narrow, slightly dilated anteriorly ;
columella with four prominent plications in the ephebic stage ;
and sometimes with five in the gerontic, owing to a very small
one being developed anteriorly.
The fusiform shape of the shell, the subcancellate aspect of
the external ornament, and the size and general character of the
protoconch, are very distinctive.

Fusimitra, auct., non Conrad, Proc. Acad. jS'at. Sci. Philad. vol. vii.
1855, p. 261.
Much confusion has arisen, over Conrad's Fusimitra, and it is
commonly believed that that author never properly described it.
Thus, Tryon^ remarks that Fusimitra is " uncharacterized,"
and gives the date as 1865, from the "American Journal
of Conchology, vol. i. p. 25 " ; he also quotes M. cellulifera,
Conrad, in connection therewith. Dr. Paul Fischer'^ gives the
same date, and quotes Conrad's species mentioned as the type.
M. Cossmann ^ seems to have felt the necessity, under the circum-
stances, of putting Fusimitra on a firmer basis, and gives a
complete diagnosis of it, also quoting M. cellulifera as the type.
Professor Dall* states that Fusimitra "never had any value,
and Conrad's original list contained the precursors of species as
different as M. wandoensis and M. swainsoni, Brod.," from
■which it is clear that he also accepted the date as 1865; and
Dr. Dall further states* that " ilf . cellulifera, Conrad, was the first
species " mentioned.
The modern authors quoted do not appear to have been aware
that Conrad' described Fusimitra ten years prior to 1865, and
that it is perfectly recognizable. In describing it Conrad says :

lines ; aperture narrow ; plaits, two prominent and two obsolete,
or much smaller than the others ; beak elongated." The author
then remarks: "To this subgenus belongs M. conquisita, Con.,
and M. mississippiensis, Con., of the Vicksburg deposit," and
describes in detail a new species called " M. {Fusimitra)
weUingtoniV And these three are all the species mentioned by
Conrad on that occasion. Consequently we must take one of
them as the type of Fusimitra; M. cellulifera is not admissible
for that purpose.
This interpretation puts a different aspect on Fimmitra as
usually understood ; and that term must be reserved for long
forms of MiTEiDiE like M. mellingtoni, closely allied to Mitra
(^sensu stricto).
The shorter forms, contracted anteriorly and for the most part
longitudinally costated (formerly called Fusimitra), must receive
another name. Such forms bear considerable resemblance to
Costellaria, Swainson,* which, however, is typically not so much
contracted in front, being thus devoid of a beak-like pro-
longation. They approach still nearer to the genus JJromitra,
Bellardi, in which the Australian forms here described are
included. The protoconchs of typical species of Uromitra from
the Piedmont Basin are more pointed and elevated than those
of the Tertiaries of the Antipodes, otherwise the resemblance is
very close.

their appearance by the development of a fold anteriorly. The

turriculate whorls, and in the body-whorl being biangulate. The

Protoconch similar to that of U. leptalea. In the brephic stage
it must be difficult to separate this species from young individuals
of TJ. paucicostata, and they are unquestionably of common origin.
127
The differences between the two species, however, become more
accentuated as the neanic stage is reached in each case, aad with
the adults the separation is well marked.
In general, it may be stated that the shell is small and turri-
culate ; but the costis are closer together and more striate than
in the last-mentioned species. Peculiar characters are the com-
paratively sharp angulation in the vicinity of the suture, and the
absence of nodosities on the anterior portion of the body-whorl,
which is occupied by prominent transverse threads. The number
of columellar plications varies from three to four ; but the material
at the writer's disposal is not abundant enough to enable their
development to be traced.

Shell very small, fusiform, narrow ; protoconch. similar to that
of W. exilis and TI. leptalea ; whorls three in number, slightly
convex, ornamented by obtuse longitudinal costae on the earlier
whorls, and these become comparatively inconspicuous on the
body-whorl of the adult, being reduced to mere undulating
corrugations ; the suture is slightly marginate. The last whorl
is much attenuated and drawn out anteriorly ; aperture elongate,
outer margin lirate within, columella with four plications, which
have the appearance of being continued as spiral ridges round
the anterior portion of the body-whorl.
The obtuse, rather distant costos on the earlier whorls, the
comparatively smooth body-whorl of the adult, and the peculiar
anterior prolongation, are features enabling U. semilcevis to be

The external configuratioii of this shell is that of a typical
Terehra, but the protoconch is distinctive, and closely resembles
that of the species of Uromitra already described, whilst the
columella is furnished with four stout, oblique plaits, becoming
progressively larger antero-posteriorly. The whorls are longi-
tudinally costate, and a narrow band accompanies the well-marked
suture. The anterior portion of the body-whorl is constricted,
and is spirally corrugated. It has certain affinities with Pyrami-
mitra, Conrad, which, however, is not much constricted anteriorly,
and only carries two columellar plaits.

Ifone of the specimens in the Museum possess a well-preserved
protoconch, which, however, appears to be small and obtuse. The
ordinary whorls are four in number, convex, depressed posteriorly
in the neighbourhood of the suture, and marginated. They are
ornamented with oblique costfe, fine transverse strisE, and spiral
threads in front of the antesutural depression. Professor Tate
remarks [op. sxipra cit.) that the aperture is "narrow-oblong,
contracted in front to a short broadish, bent, and slightly reverted
beak. Outer lip slightly ascending on the penultimate whorl,
slightly emarginate at the suture, smooth within ; columella with
four rather distant, transverse plaits."
The species appears to be very variable. The drawing accom-

Shell lanceolate, fusiform, prismatic. Professor Tate describes
the protoconch (Plate V. Figs, ba-h) as follows: "Apex of two
and a half whorls, medially angulated ; the anterior unicostate
and projecting beyond the succeeding whorl, the next narrower,
smooth, and ending in an upturned lateral point." Whorls from
six to seven in number, convex, deeply spirally sulcated, and
crossing the longitudinal costaj ; the latter are well elevated,
sliarp, and distantly spaced ; those on the body-whorl are ap-
proximately in line with those on preceding whorls, producing
a prismatic appearance, though this phenomenon is not so well
132
marked in the younger stages of growth ; aperture ovate, con-
tracted in front ; columella slightly twisted ; anterior canal very
long, sinuous, and almost closed.
The protoconch of this species is peculiar, and it may hereafter
lead to the establishment of a new subgenus for the inclusion
of this and kindred forms of Fusus. The sharp point at its
commencement, the granulated character of the earlier portion
generally, together with the irregular scar-like ridge (Plate V.
Figs, bor-h), are suggestive of a pre-existing horny protoconch,
similar to that found in living Scaphella.
M. Cossmann ' doubtfully referred F. hexagonaUs to Latirofusiis,
but although the columella is twisted it carries no plication, at
least in any of the Museum specimens. A remarkable feature in
this shell is that the growth-lines are raised into arched scales at
the suture.
The figure accompanying Professor Tate's description indicates
that the longitudinal costa3 are absent on the body-whorl. This
appears to be merely an individual characteristic, as a specimen in
the Museum, of older growth, apparently, than the type specimen,
still retains the angulate costse to the end ; though, unfortunately,
the anterior canal is broken off.

drawing such a fine distinction, especially if we consider that
slight curvature in the columella is due to the merely mechanical
requirements of the animal. The protoconchs of the only two
specimens in the Museum collectioa are not well enough pre-
served for description; but they appear to be of the same "general
character as in F. hexagonal^. The shell is narrow, with an
elevated spire; whorls convex, angulate, with a median serrate
keel and subsidiary spiral lines elevated on the longitudinal
ribbings, and crossed by fine growth-lines; aperture angularly
ovate; outer margin thin, striate within; columellar border ex-
cavated, covered by a thin deposit of callus; anterior canal very
long and sinuous.
Except for the excavated columella, the curved canal, and
the longitudinal costae, this shell resembles F. serratm, Deshayes
of the Middle Eocene of the Paris Basin.

_ Shell small, elongate, fusiform, thin; protoconch similar to that
m typical forms of the genus, it is much elevated, composed of
one and a half smooth turns longitudinally striated towards the
anterior; the shell in the brephic stage suddenly develops a strong
median carina which rapidly becomes tubular at intervals and
continues to increase in size to the body-whorl, imparting an
angulose character throughout. In front of this in the brephic
stage is developed a minor keel of a similar description, and at
a slightly later period of growth a small one makes its appearance
posteriorly between the median carina and the suture. Sub-
sequently others are gradually interposed until the penultimate
whorl in the adult carries five such keels. The mode of growth
IS thus of a different character to that of most species of the same
group, in which the main features of the ornament are foreshadowed
at a very early stage.
134
Professor Tate, in describing the ornament, says: — "Whorls
squarely rounded, deeply imj^ressed at the suture, with five
encircling ribs covered with tubular hollow spines, or slender,
vaulted, pointed scales ; the middle rib on the angle of the whorl
stouter than the rest, and furnished with long spines. Last whorl
shouldered and subtabulated, with two or three threads rarely
wanting on the posterior slope; the rounded base and canal with
equidistant similar spiral lirse, one or two on the canal are stouter
and provided with larger spines. The transverse ornament is very
peculiar, consisting of imbricating lamellae, more or less radially
disposed around the bases of the spines, and the bundles of one
row somewhat alternating with those of the next."
The apertui'e is pyriform ; outer margin slender, crenulated ;
columellar border covered with a thin deposit of callus which
is continuous with the outer margin ; columella slightly excavated,
twisted anteriorly, and terminating in a very long anterior canal.
The special character of the ornament and mode of growth
of the shell are not very typical of Fusus, but the protoconch
certainly is, as previously remarked ; and the differences mentioned
are not sufficiently important to remove the species from Fusus,
sensu stricto.

Shell very thin, fusiform ; with an elevated spire ; protoconch
composed of two smooth rounded turns ; whorls angular, compressed
into a narrow keel, serrate on the margin. The other ornament
is desciibed by Professor Tate as follows: — "Last whorl with the
posterior slope convex, depressed behind the keel, and much more
so at the suture; the rounded and contracted base is produced
into a long, rather broad, somewhat flexuous beak ; ornamented on
the posterior slope with numerous inconspicuous sj)iral threads,
LATIEOFUSUS. '135
and towards the middle by two or three prominent ones, crossed
by growth-lines which are raised into minute scales on the larger
lira?; bases of serrations with rounded ridges, conformable with
their curvature. Base of body-whorl encircled by a slender keel,
which is coincident with the posterior angle of the aperture ; the
whole surface roughly cancellated by numerous unequal spiral
threads and lamellae of growth ; beak encircled with spiral threads
and two or three ridges carrying vaulted scales." The aperture
is pyriform, opening widely anteriorly and angulate at the outer
margin ; columella slightly twisted ; anterior canal long, open.
As mentioned on p. 54, this species bears considerable external
resemblance to certain forms of Columbarhm, and it would have
been included in that genus only that the protoconch is different
and more nearly resembles that of a Fums. Further, the aperture
is more open and the columella is not covered in the same manner.
The species is by no means a typical Fusus, as exemplified, for
instance, by F. colon. For further observations on its systematic
position see ante, p. 54.

rounded; anterior canal long, straight, almost closed, the external
aspect merely presenting a narrow slit; columellar border often
detached and having one or two oblique plications anteriorly.

Shell elongate with tapering spire ; protoconch not well preserved
in the Museum specimens, but evidently smooth or slightly pointed
at the commencement and longitudinally costated anteriorly ;
whorls but slightly convex, costate, spiral ridges well pronounced,
crossed by irregular lines of growth, and, in the brephic stage,
slightly cancellate ; body- whorl inflated, descending sharply in front
to join the long anterior canal, spiral ridges very prominent and
becoming oblique and undulating on the canal proper ; aperture
rounded, contracted in front; outer margin rather thick. Urate
within ; inner margin detached from the columella, carrying a small
plication anteriorly and another on a slight callosity posteriorly ;
canal almost closed.
The species is variable in regard to its ornamentation, some
individuals having hardly a trace of longitudinal costse ; the bolder
spiral ridges commonly have a single lineation between them.
Compared with L. funiculosus, Lamarck, with which M. Cossmann'
thought it might possibly be synonymous, we find that L. aciformis
is proportionately narrower and does not possess the latiriform
longitudinal costse so characteristic of the Paris Basin shell. The
protoconch of the latter is, relatively, much smaller, and the shell
as a whole is more solid.

[Mem. Soc. Hist. Nat. Paris, 1799, p. 73.]
The animal of Fasciolaria closely resembles that of Fusus, and
the two genera are unquestiouably of the same origin. It
is difficult to satisfactorily separate the shells in the recent state,
and increasingly difficult as we pass from recent through older
deposits into the Eocene. In general, Fasciolaria may be dis-
tinguished in having a shorter spire, more inflated body-whorl,
a wider and more sinuous or flexuous canal ; but the oblique
plications on the anterior portion of the columella are the principal
differentiating characters.

Shell fusiform, broad ; protoconch composed of two smooth,
bulbous turns, the anterior part being longitudinally corrugated,
though the rough costae are not immediately connected with the
ornamentation of the whorls proper ; spire elevated and tapering ;
whorls medially serrate, the serrations being flattened, their
posterior surface leading by a sloping, undulating platform, up
to the suture ; this broad platform is spirally lineate, the lines
being of unequal size ; in front of the median serrate carina are
three minor ones of similar character, between which are numerous
undulating spiral lines j the anterior portion of the body-whorl is

also encircled by cycles of lineations, and the •whole are rendered
slightly uneven by the passage of the closely-set growth-lines ;
aperture ovate, but contracted and drawn out in front; outer
margin thin, striate, and Urate within; columellar border smooth,
with three conspicuous, drawn-out plaits, situated anteriorly ; canal
long and sinuous, especially in the adult.
One specimen in the Museum collection is larger than the type
as measured by Professor Tate ; its dimensions are given below.
This species is of the same general character as the living
F. papulosa, Sowerby, which Tryon' says is the young of
F. gigantea, Kieuer ; the former name, however, has priority.
The spire of the fossil is relatively shorter, the whorls are more
serrate, and the anterior canal is longer.

This species differs from F. cristata in having a less elevated
spire, a shorter anterior canal, and in being less spinose, though
the general character of the ornament is somewhat similar. The
protoconch is composed of two smooth globose turns, the front
portion being striate and obscurely costate ; its junction with the
ehell in the brephic stage is very abrupt. The columella carries
three plaits, the largest being situated anteriorly, and bordering
a sharp twist leading to the curved canal.

Shell fusiform ; spire moderately elevated ; protoconch similar
to that of F. cristata and F. rugata ; earlier whorls flatly
convex, and graduating to tabulated in the two anterior volutions.
Professor Tate describes the ornament as follows: — "Anterior
whorls with nine plications to each whorl ; plicae narrowly
rounded, elevated into sharpish conical tubercles at the shoulder,
separated by wide, shallow, and open furrows, dying out on the
posterior slope and on the base of the body-whorl ; the ornament
consists of acute spiral ridges, alternately large and small (about
twenty on the penultimate whorl), separated by rather wider angular
furrows, roughened by transverse lamellas of growth." Aperture
ovate, contracted both in front and behind ; outer margin crenu-
lated, oblique, and having closely-set, interrupted lirse within ;
inner margin detached from the columella in adult specimens, with
a prominent fold at the posterior extremity near the suture, and
a very oblique plication bordering the entrance to the canal from
within, with two or three smaller ones behind ; the detached inner
border is continued to the extremity of the long, twisted, anterior
canal, creating a pseudo-umbilicus.
This species has considerable analogy with F. rngata, and,
indeed, they are barely worthy of separation specifically. The
latter, however, has fewer and more rapidly enlarging whorls,
which are about equally sloping from the periphery to the suture.

The spire of this shell is more elevated than in F. cnjptoploca,
it is more tapering and narrower ; the ornament on the whorls
is of the same general character ; the aperture is narrower and
drawn out ; the columellar border is often detached, and carries
two small plaits in front. In the adult the columellar plications
are barely perceptible, being situated well within the aperture,
so that the shell is somewhat like Aptijxis, Troschel, with which
subgenus it is unquestionably closely allied. The passage from
Fusns to Fasciolaria may be readily understood from a consideration
of this species.
F. decipiens bears considerable external resemblance to Fasus
vigrirostrafus, E. A. Smith, living in the seas of Japan, south of
Corea; but the latter species, though having a twisted columella,
posses.scs no plaits, and is a true Aptyxis.

This species differs from F. decipiens in the mode of development
of the longitudinal costse, in minor details of ornament, and in
having a comparatively straight columella and canal. It cannot
be classified with Fusns, because of its columellar plications.

Shell fusiform, turreted, spire costate ; aperture oblong, outer
margin thin by comparison with the general solidity of the
shell, crenulate ; columellar border slightly twisted, carrying two
or three small oblique plaits anteriorly ; sometimes umbilicate ;
anterior canal rather long.
LafArus differs from Peristernia (in which the majority of the
species of Latirus here described have been included by Australian
143
authors) in having a longer spire and canal, whilst the columellar
plaits are more central. The presence of an umbilicus in Latirus
has also been regarded as a differentiating character, but it is not
constant. On the other hand, Peristernia is credited with having
a recurved canal, in which particular many of the Australian
fossils here called Latirus agree with it, though their canals are
long. It is questionable whether the slight and inconstant
differences indicated warrant generic separation, the distinction
between Latirus and Peristernia being entirely arbitrary. How-
ever that may be, the Australian forms alluded to are, in the
ensemble of their characters, more nearly related to the former than
to the latter.

the peripheral subangulation ; body-whorl sloped and constricted

corrugated lines of growth persist, and the spiral lineations are
very conspicuous ; aperture ovate, deeply channelled in front ;
outer margin curved, lirate within ; inner margin enamelled, the
enamel continuing from the suture, in the neighbourhood of which
is a small denticle ; columella excavated, umbilicate, having a
small oblique fold opposite the entrance to the canal ; the latter
is long, broad, curved, and slightly turned up at its extremity.
The columellar fold can hardly be termed a plication, and is not
so well pronounced as in the majority of characteristic species of
Latirus. Professor Tate discusses its affinities at some length.

Spire more elevated than in L. approximans ; whorls obtusely
costate, nodose at the periphery, and spirally lincate ; aperture
rounded; outer lip rather thick, faintly Urate within, and having
a prominent denticle in front ; columella concave, carrying a bold
plait juxtaposed to the denticle referred to, and two or three
smaller plaits or elongate tubercles behind ; canal rather long
and bent.
Its nearest ally is L. morundianus, Tate (not represented in the
Museum collection), which, however, is much larger; whilst the
whorls more rapidly increase in L. murrayanus, its tubercles are
relatively smaller and are trisected. The protoconch of the present
species (Plate V. Figs. 6a-i) is large, convex, composed of two
and a half turns, the earlier portion being oblique with reference
to the axis of the shell, the later part bearing longitudinal striae ;
the shell in the brephic stage is boldly, longitudinally costate and
spirally lineate.
Conchologically L. murrayanus resembles "Murex^^ (ife^-, Gmelin,
the type of the genus Afer, Conrad ' ; whilst it also has some
affinities with " Tudicla " porphyrostoma, Adams and E-eeve, the
type of the genus Streptosiphon, Gill,^ which the present writer
believes to be synonymous with Afer. The claims of the term
Streptosiphon to priority do not appear to rest on very secure
grounds. Fischer' admits that Afer is synonymous, but retains
the name Streptosiphon, as Conrad did not define Afer. As Tryon *
says, although Conrad did not describe his genus, he made Murex
afer (or Fusus afer), Gmelin, the type of it; from which it is not

difficult to see what Conrad meant. "Whatever views we may-
hold as to the propriety or otherwise of making genera in that
fashion, Afer has as much right to stand as many other genera
established in the same way.
L. murrayanus differs from both Afer afer and A. porphyrosUma
in the character and development of the protoconch, in which
respect it more nearly resembles the Australian species here classed
as Latirus. With this exception the separation of the species from
Conrad's genus is purely arbitrary, and conchologically it is inter-
mediate between the two genera mentioned.
The form found at Table Cape, Tasmania, and described by
Mr. G. B. Pritchard in the memoir above cited, is more costate,
and the whorls are not so distinctly angulate as in typical examples
of the species from the River Murray. The species appears to be
very variable.

Shell fusiform, spire elevated, staged ; protoconch similar to
that of L. murrayanus ; whorls spirally ridged. Described by
Professor Tate as foUows : — " Ridges angular, acute, three or four
of which on the median portion of the spire-whorls forming keels ;
the broad concave furrows with a thread, crossed by straight
distant striaj. On the body-whorl the ridges are more serrately
cut by the transverse striae than those are on the spire." Aperture
ovate, broadened outwardly ; outer margin Urate within, with a
large denticle at the entrance of the canal ; inner margin covered
with a thin deposit of callus, sometimes partially detached, carrying
146
an obscure tubercle posteriorly and a strong oblique plait (juxta-
posed to the large denticle referred to), together with a few small,

Much more tumid than either L. interlineatus or Z. suhui
though belonging to the same group. The shell is turbinate ;
protoconch similar to those of the two species mentioned ; whorls
substaged, strongly spirally ridged, the ridges being relatively
far apart and unequal in size, interspaces roughly corrugated,
especially on the body- whorl of senile examples, lines of growth
occasionally breaking through, obscurely longitudinally costate,
this feature being most noticeable in the neanic stage of growth ;

be regarded as an extreme form of that species; the whorls are
more regularly convex, the spiial ridges more flatly rounded,
and there are other minor differences in the ornament which led
its author to regard L. subundulosus as a distinct species.

Latirus tatei, sp. nov.
[Plate V. Figs, la-b.']
Shell small, fusiform ; protoconch smooth, composed of two and
a half turns, the earlier portion being lateral and very small,
the suture is bordered by a slightly elevated keel seen only in
well-preserved specimens, surface microscopically granulate ; the
anterior portion of the protoconch is at first somewhat inflated,
and then becomes constricted and longitudinally striated as it
passes into the brephic stage ; spire moderately elevated, with five
sliort, convex whorls; ornament consisting of widely distant, broad,
obtuse costse, extending from sutui-e to suture, except over the
narrow, undulating, striated band bordering the suture posteriorly,
regarded from above the whorls appear polygonal, commonly
hexagonal ; the body- whorl in the adult is frequently deprived
of these, but is furnished witli a thick, almost varicose anterior
margin ; surface of the shell strongly spirally lineate, a thin
lineation alternating with a bolder one in the later stages of
growth, the interruptions of the lines of growth producing a
semi-granulate and undulating appearance ; aperture ovate, broadly
channelled in front ; outer margin thick, lirate within, the callosity
being continued round the acute posterior channel and terminated

on the inner border by a conspicuous denticle ; columella excavated
and carrying an acute fold anteriorly, with traces of accompanying
granulations in the gerontic stage ; canal moderately long and
slightly bent.
Compared with L. murrayanus, it is much smaller, though of the
same general build ; it is relatively more elongate, whilst the
obtuse costae, plain body-whorl, thickened outer margin, and
the fewer number of plications on the columella in the present
species are very characteristic, readily serving to distinguish it
from all the other species of Latirus.

Genus LETJCOZONIA, Gray.

This genus, closely allied to Latirus, is more globose, has
a short, keeled spire, a very short anterior canal, excavated
columella with three or four obliqiie plications, the outer margin
being jjlicated internally and especially characterized in typical
examples by a prominent and often very long denticle on the
forepart, opposite the columellar plications.

Shell fusiform, solid ; whorls angulate at the periphery, where
broad, undulating, longitudinal costae are compressed, producing
serration in typical examples; body-whorl carrying one or more
lEUCOZONIA. 149
nodose, distant, spiral carinte in front of the peripheral angulation,
and sharply depressed half way between the latter and the end
of the canal ; surface of the whorls bearing several more or less
conspicuous, undulating spiral lineations ; aperture ovate, broad
in front ; outer margin thin, bearing a small tooth-like projection
anteriorly, lirate within, grooved posteriorly ; inner margin
furnished with one or two salient, elongate ridges bordering the
posterior channel, excavated ; columella umbilicate, smooth, and,
typically, carrying four plications, the one in front being smallest ;
anterior canal short, broad, and slightly bent.
This species is exceedingly variable, but the specimens commonly
found in the West Indies, and particularly from St. Vincent,
are typical, and are almost identical with the specimen from
the Pliocene beds of the Chatham Is., in the Museum collection.
Living examples have been obtained from the west coast of
Africa, Florida, and Brazil, as well as in the West Indies.
Compared with Latirus barclayi, Reeve, the whorls of the
spire are similarly ornamented, but the aperture of the last-
mentioned species is narrower, the columellar plaits are smaller
and more numerous, and are not in the same position, whilst the
canal is very much longer.
This shell is commonly known as L. cingidifera, Lamarck, but
the name here adopted has priority. This fact has been recognized
by authors,' but L. nassa appears to have been ignored because
Grnelin included other species in his description and references,
a view which cannot be entertained. Following usage, we consult
the first reference given by Gmelin,- which is undoubtedly the
species under description, and which should therefore bear the
name of nassa.

Lagena, Schumacher, Essai jS'ouv. Syst. Habit. Testaces, 1817,
p. 240; non Walker and Boys, 1784; non Bolten, 1798.
Distinguished from typical examples oi Leucozonia by the absence
of keels on the whorls, the latter being rounded ; the shell is
bucciniform and devoid of conspicuous ornament, whilst the
denticle or tubercle (when present) on the outer margin is
extremely rudimentary.
The name Lagena, Schumacher, commonly employed, is pre-
occupied by that given to the well-known genus of foraminifera
by Walker and Boys, and it refers also to one of the Tritonidse,
if Bolten's work is to be accepted. Plicatella, Swainson ' {non
Schmidt, 1870), is sometimes alluded to as being synonymous
with Lagena, but the first species mentioned by that author as
ascertained on reference to the work he quotes,^ is Fusws polygonus,
Lamarck (erroneously given as ^^ polyzona'" by Swainson), and
that has been selected by Dr. Gray^ as the type of Plicatella.
Swainson substituted the last -mentioned name for Polygona,
Schumacher,* rejected on account of being preoccupied in Botany,
which, however, is not a valid ground for exclusion following the
rules of nomenclature as usually interpreted at the present day.
If, therefore, we have recourse to Polygona, we find on reference to
the type quoted by Schumacher that that generic name could
not possibly apply to such forms as he included in the genus
Lagena. The Lagena of Klein,^ being pre-Linnean, ought not to
be recognized. Under these circumstances the present writer
cannot, in suppressing Lagena, Schumacher, utilize either Polygona
or its synonym Plicatella, and now suggests the name Latirolagena
instead, as indicating its affinities with Latirus.
It is related to Mazzalina, Conrad, but the type of that genus
{M. pyrula, Conrad) is strongly plicate, the several plaits being
implanted obliquely on a profoundly excavated columella ; that

Shell bucciniform, globose, solid ; protoconch (Plate V. Figs. 8a-5)
composed of one and a half turns, the earlier portion being
exceedingly small, subsequently becoming large, much inflated and
oblique with reference to the axis of the shell, the later portion
is distinctly longitudinally costated, which ornament obtains to the
fracture denoting the commencement of the brephic stage of growth ;
whorls to the number of four, convex, slightly concave in the
neighbourhood of the suture posteriorly, and ornamented with
closely-set spiral lines, some of which are regularly and distantly
spaced and much more accentuated on the anterior half of the
body-whorl, smaller ones appearing between; lines of growth
conspicuous, causing minute granulations at the points of inter-
section with the spiral lineations ; aperture ovate, broad in front ;
outer margin sinuous, Urate within; columellar border smooth,'
excavated, carrying three slightly oblique plaits anteriorly, each
terminating with a compressed denticle ; canal short and broad.
The costae on the anterior portion of the protoconch are very
remarkable, this characteristic not being perpetuated in later
stages of growth, and seeming to indicate that Latirolagena had its
origin in costate forms such as Latirus, or Faseiolaria. Turning to
living examples of the subgenus, we find in certain individuals
of L. leucozonalis, Lamarck, a persistent attempt to preserve and
even to accentuate the costate character referred to, the costa;
remaining even in later stages of growth. Typical examples
of that species, now living in the West Indies, and of its ally
L. mhodrata, Gray, found in the Bay of Montija, West Columbia,
closely resemble L. staminea. L. smaragdula, Linnjeus, of the
Philippines, is more globose, has a more profoundly excavated
columella, a shorter canal, and wider aperture than has the
last-mentioned fossil species.

Shell thin, usually fusiform, whorls rounded, typically smooth
aud striated ; spire elevated ; columella plain ; canal produced
and often recurved.
The term Sipho, commonly employed for this genus, was first
proposed by Klein,' but that author's work, being pre-Linnean,
cannot be accepted. The name was brought on by Morch in
1852, as above indicated. But in 1847 Beck had already
proposed Tritonofusus, which is synonymous with Sipho, Klein, as
interpreted by Morch, and must therefore take priority.
Even if that were not the ease, Sipho (Klein), Morch, could not
be adopted, as T. Brown had employed the term in 1827.^ If
that be objected to on the ground that the work in which it was
suggested was merely a collection of plates without descriptions,
Sipho [Si/pho), Brown, must fall in synonymy with Puncturella,
Lowe, 1827, though Brown subsequently attempted^ to establish
his term.
In reference to Sipho, 0. Fabricius, 1823 (not 1822, as commonly
quoted), that name was proposed in an auction catalogue,* referring
to the books, natural-history specimens, etc., which belonged
to Bishop Fabricius.* Murex infundihulum, Gmel., appears to be

and if any value attaches to an auction catalogue, for systematic
purposes, Sipho, Fabrieius, must be quoted in synonymy with
Latirus, Montfort, 1810.
The name Tritonofusus was, according to Herrmannsen (see
above), proposed by Beck in 1846, and was at that time apparently
a MS. name attached to some specimens in the Eoyal Museum at
Copenhagen. During the meeting at Kiel above referred to, the
conchological section saw the specimens, and an account of them
was published in the " Amtl. Bericht " quoted, where the name
Tritonofusus, with its type, are set forth, but the reporter's name
is not given. In all probability the writer of the account was
Herrmannsen, who was present at the meeting. In any case, he,
in 1847 {o}}. supra cit.), quotes Beck as the author of the genus.

The young of this species somewhat resembles S. longirostris,
though the sculpturing on the whorls of the latter species is
more rugose, and the dentate tubercles on the periphery are much
more pronounced. The protoconch of S. mandarina is relatively
larger, and it is turbinate. The costate and tuberculate ornament
is lost with advancing age, and adult specimens possess bolder
spiral ridges. The inner margin, smooth in the young, becomes
covered with a detached plate in the adult and senile stages.
Fusus zealandicus, Quoy and Gaimard, is inseparable from the
present species, as is now generally recognized.

This is a shorter and smaller species than S. viandarina ; it is
relatively broader, and the spinose tubercles on the periphery
extend to the body-whorl even in the adult; the columella is
more deeply excavated, whilst the anterior canal is sharply twisted.
But the most characteristic difference, perhaps, is the protoconch,
which is conoidal, and composed of four and a half smooth turns,
commencing as an extremely minute point, and regularly increasing
in size, instead of being large, obtuse, and irregular, as in
S. mandarina.

Genus PSEUDOVARICIA, Tate.
[Trans. Eoy. Soc. South Aust. vol. s. 1888, p. 146.]
The following description of this interesting genus is given
by its author: — "Shell cylindroid-fusiform, smooth, spire obtuse,
wliorls with a few remote and non-continuous imbricating varices ;
canal very short, wide, columella smooth, slightly arched. The
varices are not produced as ordinarily by an outward thickening
or bulging of the shell wall, but appear as abrupt step-like
interruptions to the regularity of the spiral curve, and seem to
indicate that each periodic mouth was slightly margined with
enamel, and the new growth to have been commenced from
within, so that the successive growths are not in the same plane."
160 PSEUDOVAKICIA.
The phenomena connected with the columella, though roughly
indicated in the figure accompanying Professor Tate's description,
seem to need further explanation. Although the pillar is smooth,
yet even in the brephic stage it is seen to be slightly twisted,
a character perpetuated through the neanic stage, though not
prominent until the ephebic stage was attained, when a small,
inconspicuous fold was developed with another just visible on
the margin of the columella anteriorly. It was not until the
extreme ephebic or, perhaps, the commencement of the catabatic
stage, however, that these two folds or corrugations became well
developed, and their accentuation, as seen in the largest specimen
in the Museum (larger than that described by Professor Tate)
appears to be due to senility. It somewhat resembles Andonia,
Harris and Burrows, from the Upper Tertiaiy of Italy and the
Eocene of North- Western Europe, but the nature of the protoconch
and the peculiar development of the varices are highly distinctive.

p. 146, pi. vii. figs. 9a-f.
Protoconch (Plate VI. Figs. \a-l) composed of two and a half
broad and narrow, slightly angulate turns flattened at the apex;
smooth, but bearing microscopic spiral lineations and longitudinal
strife, best developed on nearing the shell proper. It is almost
impossible to define the precise limits between the protoconch
and the brephic stage ; the longitudinal striae run in sets divided
by the varices, and the striations undoubtedly begin on the
protoconch, though they are extremely minute to commence
with. In that vicinity the "varices" are close together, and
are mere striae larger than the others. As this is the only species
hitherto described as belonging to the genus, much of what has
been said in the generic review applies specifically also. In
addition, it may be mentioned that the shell is composed of
seven slowly-increa.sing whorls, flatly convex, with a very narrow,
high-sloping shoulder defined by a strong thread. The whole
surface is finely transversely striated ; the strite become larger
near the suture and prominent on the body-whorl anteriorly.

The examples of this species in the Museum collection are not
in a good state of preservation. Professor Tate describes it as
follows : — " Shell oblong-fusiform, similar to P{isania) rostrata,
with more rapidly increasing whorls, base less abruptly attenuated,
canal shorter, costae fewer and stouter. Whorls below the apex
four, costae slightly curved, rounded, about as wide as the inter-
spaces, 16 on the penultimate whorl, obsolete or only faintly
developed on the body-whorl."
M. Cossmann ' includes Cantharus as a section of Tritonidea,
hence the above synonymic reference.

Subgenus DENNANTIA, Tate.
[Trans. Roy. Soc. Soutli Aust. vol. x. 1888, p. 161.]
This differs from Euthria, sensu stricto, in being much more
elongate, in having a relatively smaller aperture, by the possession
of a more distinct and dentate plait on the anterior portion of
the columella, and by a small denticle projecting from the outer
margin anteriorly. At the same time it is not worthy of generic
separation, and the present writer has some diffidence in regarding
it otherwise than as an extreme form of Futhria. In this
connection it is interesting to note that Euthria, sensu stricto,
a common Mediterranean species, has recently been discovered in
Australian seas.

more prominent and erect longitudinal costse, in being augulate at
the periphery, and the whorls are more tumid. Its aperture is
relatively shorter and broader, and wider in front, whilst the

Subgenus LOXOTAPHRTIS,' nov. subgen.
Shell narrow, elongate ; protoconch smooth, obtuse ; spire
turriculate, whorls angulate, ornamented by longitudinal costae
and spiral threads ; aperture narrow, acute at both ends, wider
towards the middle, channelled in front ; outer margin thin,
slightly reflected outwardly, bordered by a strong varix, faintly
lirate within, and continued round the posterior channel, or acute
groove ; inner margin continuous with the outer and consisting
of a shining plate affixed to the body-whorl, and covering the
•whole columellar border from which it rises, and is often detached ;
this leaf-like covering is slightly corrugated, but in no sense
plicate or tuberculate, it borders the twisted, oblique canal, and
gives rise to a small umbilicus.
The entire peristome, and especially the disposition of the
enamelled plate constituting the inner margin, with its raised
edge, sugf^est affinities with Nassaria, Link {Hindsia, H. and
A. Adams), but the latter has not the same contour, and is
furnished with denticles on the columella. It differs from Phos,
tensu strido, which is of the same general configuration, in the
phenomena of the aperture already described ; but the chief point

166 PHOS,
of difference, and which has more weight than any other in
deciding the writer to suggest its separation from Phos, properly
so called, is the character of the protoconch. In Phos the
protoconch is, typically, turbinate, the turns gradually increasing
in size from an exceedingly small beginning ; moreover, the coils
are regular, their axis being in alignment with the axis of the
whole shell. In Loxotaphrus, on the other hand, the protoconch
(Plate VI. Figs. 3«-5) has fewer turns (typically one and a half),
and is by no means turbinate, it commences by an obtuse inflation,
and quite one-half of it is oblique with reference to the axis of
the shell.

Shell turriculate, narrow, bucciniform ; protoconch (Plate VI.
Figs. 3ff-J) composed of one and a half smooth turns, the earlier
portion being inflated and implanted obliquely with reference to
the axis of the shell, later portion finely striated longitudinally
and ending abruptly ; the main features of the ornament of the
whorls suddenly make their appearance in the brephic stage (a
very unusual character), and do not apj)ear to be foreshadowed
in the protoconch. That ornament consists of prominent, slightly
oblique, longitudinal costae, with smaller longitudinal lineations
running between and obliquely over them ; and broad, irregular,
spiral threads, considerably elevated on the costae, especially at the
angular periphery, where the points of intersection are surmounted
by small tubercles, complete the sculpturing of this ornate shell.
The phenomena of the aperture have been sufficiently described
under the subgeneric heading.

Distinguished by its varicose outer margin, which presents a
thin edge, by the widespread callosity on the inner margin and
by the granose aspect of the whorls. Professor Tate remarks that
" Senile examples occur which have added another whorl, and by
reason of the posterior varix have a somewhat distorted spire."
He compares it with the living N. granifer, Kiener.
It also resembles N. vibex, Say, of the Atlantic coast of the
United States, but the protoconch of the latter is more acute,
the longitudinal cost* on the whorls are more distant and not
so oblique, and granulate ; further, the spire in the American
shell is not so much elevated, and the borders of the aperture
1

are more corrugate and callous. Dr. Dall * recognizes iV. vihex

This small species is extremely variable both in shape and
ornament, but the series examined by the writer exhibits such
gradual passages that no doubt exists that the divers forms all
belong to one species. The protoconch (Plate VI. Figs. Aa-h)
is turbinate, composed of four smooth, gradually increasing turns,
the anterior portion being faintly longitudinally striated ; the
shell in the brephic stage becomes strongly longitudinally costate,
the ribs being cut up by spiral sulci and lineations. Professor
Tate describes the ornament in some detail, and discusses the
aflBnities of the species. He finds that iV. compacta, Angas, of
Australian seas, is its nearest modern representative.

This species has considerable analogy with T. pungens, Solander,
of the European Eocene, and young specimens ai-e not readily
dilFerentiated at a cursory glance. The protoconch, however, is
very different : in T. maccoyi it consists of two smooth turns,
the earlier portion being implanted obliquely with reference to
the axis of the shell ; whereas in T. pungens the three smooth
turns are elevated and rise to a sharp erect point. Further, the
Australian species is relatively broader, and the spines and tubes
ai"e not curved in the manner peculiar to tlie European species.
Young specimens resemble T. tuhifer, Bruguiere, of the Middle
Eocene of the Paris Basin, but that species is longer, less spinose,
and the protoconch is much more erect.

This species differs from T. maccoyi, Tenison-Woods, in being
relatively narrower, the spire is much higher, it is not so
prominently spinose, though the varices bear several minute frills
which curl round, forming short tubules, leading up to which
on the whorls are some oblique costae. The intermediate tube
is very near the suture, and is larger thun any of the others.
The aperture is ovate, and the plate affixed to the columella rises
high, as in T. horridus, of the Italian Miocene.

Much smaller than any of the preceding species of Typhis, from
which it may readily be distinguished by the plainer character
of the ornament on the whorls. It is solid, not distinctly varicose,
though there are frequent breaks in the growth. Between each
of these latter the whorls rise into a curved, obtuse, plain,
longitudinal ridge, on the crown of which is a large, blunt,
recurved, flattened tubule, completely covering the suture though
detached from it. The suture may only be observed between
these large tubules, and then not very distinctly. The protoconch
is of the same character as in T. maccoyi; aperture very small,
almost circular, canal quite covered in.
It is of the same general type as T. Jistulosus, Biocchi, of the
Italian Tertiary and of our own Barton Beds, but the spire in
the Australian species is more elevated, it is minus the leaf-like
expansion ou the outer margin of the aperture, and it has not the
172
longitudinal ridge between the prominent tubules so characteristic
of the European species mentioned.

prolonged, partially closed, usually spinose.
Several of the Australian species are with difficulty allocated
to the known subgenera. The passages between Murex, sensu

say where one begins and the others end, though typical species
of each group are easily differentiated.

Shell trigonal, spire elevated; canal long, partially closed;
three foliaceous and typically spinose varices succeed each other
at regular intervals, those on the body-whorl being in alignment
■with, and joined to, the corresponding varices on the preceding
Tphorls, thus producing the trigonal shape.
It is impossible to distinguish Triplex from Cerostoma, Conrad,
in the fossil state, the principal differential characters being in
the operculum.
It is not without some hesitation that the writer admits the
synonymity of Triplex with Pteronotus.^ Perry (see above) includes

in Triplex species that undoubtedly full within the earlier
Ckicorem, Montfort, but there are others which are unquestionably
like the later Ptrronotm. Perry does not state the type of his
genus, but in a footnote he alludes to Mtirex frondosus, Linna3us,
and to the fossil Murex tripteris, Lamarck (J/, tripteroides), the
former possessing tlie essential characters of Chicoreus and the
latter of Pteronotus. If we take the first species mentioned
as the type of the subgenus, Triplex must fall in synonymy
with Chicoreus, that name having been proposed by Montfort '
one year earlier ; but if, on the other hand, either If. tripteroides,
M. fiexuo&us, or M. pinnatus (which two last are both figured
and described by Perry under his genus) be selected, we are
enabled to retain Triplex. We are fortified, to some extent, in
so doing by referring to Humphrey's work, which, although it
cannot be accepted, as being a mere auctioneer's catalogue, enables
us to see what directed Perry in his definition of the genus. The
first recognizable species mentioned by Humphrey- under Triplex
is Murex triqueter, Born ; that occurs, apparently, in Perry's
description as Triplex flexuosa, and is here selected as the type
of the genus.

Shell very thin, elongate ; protoconch composed of one and
a half smooth turns, somewhat inflated at the commencement,
and microscopically longitudinally striated in the vicinity of the
first minute yarix, which appears to denote the beginning of the
brephic stage. The foliae of the three varices are extremely thin
and much spread out ; the posterior aspect of the projections are
covered, like the surface of the shell between them, with rather
large scaly punctures, and the irregular spiral ridges of the whorls
are prolonged also on to the aliform expansions posteriorly ;

the fronts of the expansions are granose. Half-way between
the varices an obscure longitudinal rib occurs, rising into a small
tubercle at the point of intersection with the prominent spiral
ridge at the periphery. The aperture is elongately ovate, is lined
with a thin plate of enamel, which is somewhat detached from the
columella in adult specimens, and is slightly grooved posteriorly ;
outer margin crenulate, denticulate within ; canal long, almost
closed.
Except that the wing-like expansions are more fully developed,
and the aperture is not spread out, it is like M. tripteroides,
Lamarck, of the Eocene of the Paris Basin.

This species is closely allied to M. velificus, from which it differs
in not having the foliated varices so greatly expanded, a relatively
shorter spire, the intervariceal nodulations, or short, tuberculate,
longitudinal ribs, are much more prominent, whilst the plate lining
the aperture is spread out all round, and is more deeply sinuated
posteriorly.
It has considerable analogy, as Professor Tate remarks, with
the living M. rubridentatus, Reeve, in regard to shape and obliquity
of varices, but has only one intervariceal longitudinal short rib.
It differs primarily from the modern M. pmnatus, Wood, in not
having the aliform expansions interrupted, and its spire is shorter.
It is more closely allied to the Paris Basin M. trifteroides, Lamarck,
of which, indeed, it may only be a local variation. In the
175
absence of better material, however, the writer hesitates to quote
M. ctilvm in absolute synonymy with the French species mentioned.

Shell tumid, paitly trigonal ; protoconch composed of at least
two obtuse, smooth whorls, the earlier portion commonly being
turned round and buried horizontally in the succeeding turn, the
sudden twisting interfering with the symmetry of the turns as
a whole. In some cases the last turn of the protoconch envelops
tlic earlier portion of the apex. The shell is specially charac-
terized by having a well-pronounced longitudinal rib on the earlier
whorls between each varix ; there are the usual three foliated
varices on the body-whorl, but these latter are not bi'oad, and
they are discontinuous. The body-whorl is ornamented with
about twenty equidistant slender spiral threads, transversely
striated.

Shell elongate, with elevated spire, rounded whorls, and rather
long canal ; protoconch composed of one and a half smooth, obtuse
176
turns, the anterior poi'tion being spirally striated and terminated
by a sharp varix ; shell in the brephic stage strongly spirally
lineated, and having rudimentary spines ; remainder of whorls
cut up by three slightly foliated varices, crenulated at the edge,
and each bearing a large, long, hollow spine at the periphery;
the spiral ornament consists of bold, thread-like lineations, with
minor ones between and in the vicinity of the suture posteriorly ;
body- whorl contracted medially, and the prolongations of the varices
lead to projecting, curved, hollow spines on the dorsal aspect of
the columella ; aperture large, ovate ; outer margin slightly
sulcated ; inner margin covered by a thin plate of enamel, which
is detached from the columella anteriorly and spread out, bordering
the narrow, curved slit of the almost closed canal.

This species is so closely allied to M. amllyceras that a large
series of specimens would probably show that the two were
synonymous. The principal point of difference is the less pro-
nounced character of the ornament, whereby the spire at the
periphery of the whorls is much reduced in size, the varices
are not so deeply foliated, nor the edges of the latter so markedly
crenulate. M. amhlyceras has no intervariceal nodulations.
M. dennanti has a spiral carina, which becomes spinose on passing
over the varices, on the anterior portion of the body-whorl, best
developed in the earlier stages of growth ; canal long.

aperture 6'5 mm. ; length of canal 8 mm.

Murex (Triplex) otwayensis, sp. nov.
[Plate VI. Figs. 5a-d.]
Shell small, narrow, spire elevated ; protoconch composed of
one and a half smooth turns, invaded by scalariform longitudinal
laraellfe, which appear to proceed from the brephic stage of
growth, crossing the suture and affixing themselves to the pre-
ceding turns of the protoconch; varices three to each whorl
in the neanic and ephebic stages, but more numerous on the
earlier whorls, foliated, crenulated on the edges due to the
prolongation of the spiral lineations, which are far apart, not
more than four or five being developed on the penultimate whorl ;
the anterior aspect of the variceal folia exhibit the usual undu-
lating scales of growth, whilst there is a prominent hollow spine
of medium length projecting from each folium, situated posteriorly,
in the neighbourhood of the suture ; the intervariceal longitudinal
costae are about six in number on the penultimate whorl, and
their intersection with the spiral lines cause tessellation of
a peculiar character, each point of junction being crowned by an
obtuse nodulatiou ; the anterior half of the body-whorl is compara-
tively denuded of ornament ; aperture quadrate, open anteriorly,
peristome continuous except at the entrance of the canal ; outer
margin slightly reflected ; canal short, almost covered up.
This shell is more ornate than either of the preceding species
of Triplex, and forms a link between that subgenus and Chicoreus
through the medium of its variceal spines. The protoconch is
highly distinctive ; it is doubtful whether part of the scalariform
structure did not originate within the capsule, but the folia
being longitudinally continuous and unbroken from the brephic
Btage across the suture, the point cannot be definitely resolved
by the few specimens in the Museum collection. Compared with
M. contahulatus, Lamarck, of the Paris Easin, with which it
presents some analogy, the latter is found to possess more convex
whorls, is broader, larger, and is minus the intervariceal tessellation.

vol. X. p. 96, pi. i. fig. 4.
Headily distinguished from other Australasian species of Triplex
by the elementary character of its ornamentation ; it is solid,
varices three in number, and continued obliquely from whorl to
whorl, they are very narrowly foliated, and are furnished pos-
teriorly with a short blunt spine or tubercle ; between the varices
are three stout, nodulous, short costse ; aperture ovate, channelled
in front and having a deep notch posteriorly bordering the suture ;
canal short, slightly curved, and almost closed.
Tlie deep notch on the after part of the outer margin is very
distinctive. Professor Tate remarks (op. cit. p. 97) that M. tri-
nodosus is separable from the living M. angasi, Crosse, by "being
broader across the posterior part of the body-whorl, by the variceal
spine not being hooked, by the less angulated whorls, longer
canal, and by having three stout intervariceal nodulations instead
of two inconspicuous ones."

aperture and canal 8 mm.

Subgenus CHICOREUS, Montfort.
[Conch. Syst. t. ii. 1810, pp. 610, 611.]
The varices of the shells included in this subgenus are foliated,
though not to the same extent as in Triplex, and a principal
distinguishing feature is the elaborate character of the spinose
varices or foliations. It differs also from Triplex in having a
relatively larger aperture ; canal short, curved, and nearly closed.

Shell tumid, rounded, short conical spire, and broad body-whorl ;
protoconch composed of one and a half smooth turns, the earlier
p irtion rising high and is much inflated, a strong varix denotes its
termination ; shell in the brephic stage cancellate, but the varices
gradually become accentuated in the neanic stage, and carry
leaf-like expansions which increase in size as the adult condition
is approached ; there are three varices to each whorl, and these
are rendered somewhat spinose at the edge by the prolongation
of the elevated spiral ridges which form such a conspicuous part of
the ornament; between each ridge there is one prominent linea-
tion, commonly accompanied by one or two smaller threads; and
there are usually three intervariceal costae, which are subspinose
at the periphery on the later whorls ; the lines of growth give
rise to scales on intersecting the spiral ornament ; aperture slightly
oblique, ovate, peristome continuous except for the narrow slit
which communicates with the almost closed canal ; outer margin
crenulate ; inner margin lined with a thick, enamelled, reflected
plate; canal short, corrugated.
The comparative simplicity of the spinose ornament removes
this species from typical examples of Chicoreus ; but, on the other
hand, the configui-ation of the shell and the nature of the varices
are not typical of Triplex.

180
anteriorly by a small varix, beyond whicli the salient features
of the ornament of the adult are foreshadowed ; Tarices irregular,
not being in alignment from whorl to whorl, three on the body-
whorl, increasing in number posteriorly ; they are not foliated, but
rounded off, bold spiral threads passing over them, there are three
varices on the last whorl in the adult, increasing to four or six
on the preceding whorls ; whorls eight in number, subangulated
at the periphery, longitudinally lineate, scaly, and obscurely
nodose at the points of intersection with the spiral threads ; sutures
deep; body-whorl constricted, i^MSM«-like on the anterior half;
aperture ovate, open in front ; outer margin thin, curved, crenu-
late, lirate within; inner margin covered by a thin plate of enamel,
bearing three or four denticles on the forepart of the columella ;
canal of medium length, broad, open, nearly erect.
The canal is rather longer than in typical examples of Muri-
copsis, whilst the varices are not quite as numerous ; but the
tubercles on the columella, the lirae within the outer margin,
and the partial umbilicus are characteristic.

which it chiefly differs, according to Professor Tate, in having
four varices on the last whorl and seven on the preceding two
whorls, in the adult; the canal, also, is shorter, and the trans-
verse ornament is more regular and closer. The vaulted scales

This well-known shell of the Australian and Tasmanian Tertiary
is characterized by its erect, staged spire, by the frequent, long,
hollow spines which crown and terminate obtuse longitudinal ribs
at the periphery of the body- whorl, and by the free sloping
area, but slightly spirally lineated, between these spines and
the suture ; in front of the spines are bold, undulating, spiral
threads, passing over the broad longitudinal costas, and continuing
over the whole of the anterior portion of the body-whorl. The
aperture is large, ovate, well open in front ; outer margin thin,
curved ; columella excavated, covered by a thin plate of enamel,
which is detached anteriorly and causes a pseudo-umbilicus ; canal
slightly oblique, broad, of moderate length.
The absence of conspicuous varices, the nature of the spiral
ornament, the bold threads in front of the prominent peripheral
spines, and their comparative absence beliind them, are very
distinctive.

Shell fusiform, tumid, rugged ; protoconch composed of one
and a halt' smooth canaliculate turns, the earlier portion inflated
and obtuse, the later slightly contracted and ending abruptly by
u very prominent varix, or thickening ; the shell in the brephic
stage is cancellate, but at later stages of growth the prominent
longitudinal lineations involved in the cancellate structure become
developed into broad rugose varices or costiB, of which there are
six on the body-whorl ; the spiral lineations are bold, and there
are about nine of these on the penultimate whorl; lines of growth
close together, and producing minute vaulted scales in crossing
over the spiral lineations, which form the characteristic rugged-
ness on the exterior of the shell ; suture cut in, the whorls at
first sloping gently away from it and then becoming rounded ;
body-whorl constricted towards the anterior, but lineate and
rugged throughout ; aperture round, slightly opened in front ;
outer margin thin, the spiral ornament reflected within ; inner
margin smooth ; columella covered by a thin plate of enamel
detached near the twist at the entrance of the moderately long,
curved canal ; large vaulted scales appear in the front part of
the columella bordering the canal.
This species is reiigured, as the view given by Professor Tate
hardly does justice to it, showing but one side only, and that of
not a very typical example, apparently. It approaches the genus
UrosaJpinx in that it is fusiform, and that the varices are not very
184
distinct, resembling costse. At the same time, varices are present,
an'\ IT. asperulus may, conchologically, be regarded as intermediate
between Muricidea and UrosaljJtnx.

dilated behind, slightly crenulated on the acute margin, and with
seven tooth-like ridges within ; inner lip spreading over the
columella and thinly continuous with the outer lip, with one
elongated plication near the posterior angulation, and about eight
small irregular callosities thence to the point of the pillar."
These features are not characteristic of Pisania or Latirus, but
of Si drum.

The circumstance that Triton had been used in other depart-
ments of zoology, before it was proposed for the well-known group
of molluscs which for so many years has borne the name,' has
been known for a long time to students of mollusca, but it is
only in recent years that the priority rule has been applied, when
Mr. R. B. jS^ewton^ suggested that Lampusia, Schumacher, should
be adopted. That name, however, was not proposed until 1817,
and we find that Montfort had already, in 1810, in the work
above quoted, suggested Aqiiillus, Lotorium, and Apollim, all of
which are regarded by some writers^ as subgenera of Triton,
though by others Apollon has been placed under Ranella. It is
obvious, therefore, that before accepting Lampusia, we must
examine the claims of Montfort' s genera mentioned.
Commencing with Aquillii&, the etymology of the word is
uncertain,* and in any case is hybrid. "When it is emended, in
the manner suggested by Agassiz^ and others, we hsi^e Aquilus,
or Aquila, which is anticipated by the well-known Aquila,
Brisson,* in ornithology, and by several other authors prior to the
appearance of Montfort's work. To prevent difficulty, therefore,
it is not advisable to select Aquillus, the more so that Montfort
suggested another name at the same time, in the same work,
which will do very well.
In reference to Apollon, although that has been included by
authors as a subgenus of Triton, it has also been called a Ranella.
It is certainly worthy of generic rank, and under the name of
Argohuccinum has recently '' been restored to that status (see
also p. 195), and is thus not available to take the place of Triton.
We are left with Lotorium, which we would now suggest
should be adopted for the group hitherto denominated Triton, or
Lampusia. In this view Mr. Edgar A. Smith fully concurs.

Lotorium radiale, Tate (sp.).
1888. Triton radia/is, Tate, Traas. Roy. Soc. South Aust. vol. x. p. 118,
pi. V. fig. 8.
Protoconch (Plate VI. Figs. 6a-h) consisting of two and a half
turns, the posterior portion is smooth and commences with
a somewhat inflated, elevated, obtuse point, situated laterally,
and in some instances overlapping the anterior portion. The
latter is irregularly lineated, the threads corresponding to the
principal features subsequently developed in the shell in the
brephic stage. One specimen in the Museum collection, in which
the protoconch is well preserved, shows the central lineation
broken up into small granuhxtions, homologous with the spinose
tubercles afterwards so distinctly pronounced in the ephebic stage.
The shell proper has five whorls carinated medially, from which
arise distant, compressed, tooth-like tubercles, the body-whorl
carrying a similar but smaller row of tubercles anteriorly. The
whorls are spirally and closely lineated. Prominent varices occur
at intervals, and it is noteworthy that just prior to putting on
a new varix the spinose tubercles become smaller than others
up to the preceding varix. The aperture is almost circular, outer
border lirate within, having a denticle where the deep, oblique,
anterior canal commences ; inner border thin, lirate, dentate in
front, and having a prominent callous plait posteriorly; columella
umbilicate, excavated, and twisted.

This species is allied to L. radiale in many respects ; but its
protoconch, although lateral, is highly distinctive. It is composed
188
of two turns, the posterior of which is smooth and slightly oblique,
whilst the anterior is spirally lineate. In regard to ornament
of the whorls, the compressed angulate tubercles are not rela-
tively as large as in the species mentioned, and the spiral lineations
are stronger. But the principal distinguishing features beyond
the protoconch are the prolonged anterior canal, the thin outer
border of the aperture, and the absence of pronounced lirae in
the interior; a thin columellar callosity is observable in many
individuals.

The protoconch is not very well preserved in any of the speci-
mens in the Museum collection ; the author of the species describes
it as follows: "Apex of two polished whorls; the anterior one
is high, bicarinated, and transversely striated ; the posterior one,
encircling a shallow concavity, at first suddenly narrowed, then
somewhat depressly dilated, and ending in a blunt appressed
point." Z. tumulosum is allied to Z. ci/pkus, but the shape of
the whorls is different, the latter species being much more angu-
late, and the peripheral tubercles being so flattened as to resemble
serrations, whereas in Z. tumulosum the tubercles at the periphery
are nodose and cut up by small spiral sulci. Further, the spiral
ornament of the latter species is different, the threads being
markedly granose, whilst the anterior canal is shorter.
Compared with the living Z. fusiformis, Kiener, of Australian
seas, the fossil has a longer canal, larger aperture, the denticles
on the outer margin are not so large and they are more numerous,
whilst the spiral ornament is more profuse.

it is distinguished by its gibbose whorls, which are much com-
pressed and angulated at the periphery, where immense projecting,
acute, flattened serrations are developed; the other ornament of
the whorls consists of undulating spiral lineations, crossed by fine
hues of growth; varices prominent, about three in every two

More elongated and less spinose than L. radiale or L. cypht(s,
though the surface of the shell is spirally lineate in a manner
somewhat similar to the latter. The protoconch rises to an
acute, erect point, but the remaining turns are depressed ; whorls
elevated, somewhat attenuated, six in number; varices distant,
broad and clearly defined, not spinose ; angulation at the periphery
compressly nodose, one or two spiral tuberculose and granose
lineations (more or less accentuated following individuals) in front
of the peripheral angulation, and three or four smaller rows of
spiral granulations behind ; aperture almost circular ; outer margin

Of the same general character as L. woodsi, but readily dis-
tinguished in having a different type of protoconch, which in
this species is roundly turbinate, composed of three and a half
turns, spirally striated, commencing in the centre and gradually
increasing in size, instead of being excentric, and commencing
as an elevated point, as in L. woodsi; further, the anterior canal
is much shorter, and there are three spiral rows of small, trifid
nodulations on the body-whorl.

The protoconch (Plate VI. Figs, la-h) of this species is similar
to that of L. tortirostris in being somewhat elevated, round!
turbinate, and spirally striated ; it is composed of three and a ha
to four whorls, and the strife, which are four in number, equi
distant, and very pronounced on the last turn, decrease in size
on being traced backwards, the top of the larval shell is extremely
minute and central. The ornament of the whorls is also much
like that of the species just mentioned, but there are only two
rows of tubercles, or nodulations, instead of three, on the body-
whorl, and seven intervariceal tubercles occur on the posterior
peripheral angulation. The specimens from Cape Otway are more
elongate than the type found at Muddy Creek, the body-whorl
of which is subquadrate. Examples of the young stages of
growth are almost inseparable from those of L. tortirostris, and
the latter may only be an extreme form of this species.

Genus APOLLO, Montfort {em.).
[Conch. Svst. t. u. 1810, p. 571.]
The principal distinctive features of this genus are the con-
tinuous or subcontinuous varices by which it may be distinguished
from Lotorium. Its general contour is that of Ranella, from
which it differs, amongst other things, by the absence of a posterior
groove, canal, or sinus.
Apollo is sometimes regarded' as a section of Argohuccinum,
Klein ; but that cannot be admitted, the latter being the work
of a pre-Linnean author and not brought on until Apollo had
already been suggested. If Argoluccinum is not to be regarded
as synonymous with Apollo, the differences are certainly not of
generic value, and it is here suggested that Apollo should be
regarded as the genus, and Argoluccinum, Gijrina, Schumacher,
Aspella, Morch, etc., as subgenera.

The specimen figured by Mr. Tenison-Woods refers evidently to
a very young shell, and the interpretation placed upon it by Pro-
fessor Tate (oj». supra cit.) is here adopted, though the specimens in
the Museum do not enable the pi'esent writer to control the matter.
The protoconch consists of one and a half oblique, smooth turns,
abruptly joined to the succeeding whorl. The shell is solid,
ventricose, with a short conical spire ; suture in the later whorls
hidden and surmounted by an undulating, granulose, and tuber-
culate ridge ; shoulder of the body-whorl coronate, with large,
prominent, compressed, tooth-like tubercles ; smaller tubercles ai'e
developed in front of this on the body-whorl. Aperture narrow,
outer margin flattened, inflected, and slightly reflected, dentate
within ; inner margin much expanded, projecting in front as a thin
plate over the umbilical region ; columella twisted, and f urnishetl
with a number of irregularly disposed plications.

SEMICASSIS. 199
Protoconcli of two and ti luilf smooth, depressed turns, gradually
increasiug in size from the initial portion, abruptly separated from
the succeeding whorl. The cancellate ornament, so well developed
OQ the hody-whorl of the adult, commenced to form in the earliest
part of the brephic stage. Spire elevated, subangulate at the
shoulder ; suture accompanied by a small, acute ridge ; aperture
oval-oblong, obtuse posteriorly, and rounded in front; outer margin
thickened, reflected, and dentate within ; columellar expansion
smooth, forming a thin plate anteriorly ; columella twisted, and
having several irregular plications, with here and there a tubercle
anteriorly.
A characteristic feature of the shell is the fine cancellate
ornament.
Mr. G. B. Pritchard has indicated that S. transenna, Tate, is a
synonym of this species as above shown. As Mr. Tenison-Woods
did not give a figure of S. sufflata, the present writer cannot control
the matter; but the description given by its author certainly
appears to bear out Mr. Pritchard's views.

This species diff'ers fi'om the preceding principally in the absence
of cancellate ornament, its aperture being broader and the whole
shell more ventricose. The whoiis have bold spiral bands of
unequal size crossed by fine growth-lines which lead to cancellation
accompanied by dentate elevations on the bands referred to. This
ornament is almost entirely confined to the area between the
subangulation of the shoulder of the body-whorl and the suture ;
the latter is bordered by a granulose lineation best developed in
tlie young state. The body-whorl has regularly-spaced growth-
lines with obsolete spiral linealions in front of the subangulate

Protoponch small, composed of one and a half turns implanted
obliquely on the succeeding whorl ; it is sharply defined from
the shell proper. The most interesting facts concerning the mode
of growth are to be gleaned by observation of the brephic stage.
On escape from the capsule the animal appears to have been
undecided on even the main lines of its subsequent ornament ;
and it is found at that period of growth to consist, first of all of
202 MORIO.
a number of small closely-set spiral lines intersected here and
there by obsolete growth-lines, and this in some individuals
persisted for at least one whorl. Gradually the longitudinal lines
develop into small ridges, which, after establishing small tubercles
ia the neanic stage, pass away into almost imperceptible striae
of growth. The tubercles on the shoulder of the whorl become
divided into two parts spirally at a very early period, and as
the animal arrived at maturity they are further subdivided in the
same direction. The spiral cords in the young shell develop
irregularly, but in the neanic stage they are transformed into
broad spiral ridges with concave sulci between. It is not until
the ephebic stage is reached that these ridges are crowned with
regularly spaced tubercles of similar character to those at the
shoulder of the whorl. It is interesting also to trace the develop-
ment of the broad area surrounding the suture. In the brephic
stage no indication of this is apparent, at least in any of tlie
specimens in the Museum ; but immediately afterwards an oblique
sulcus is gradually formed, which broadens and becomes flat
with age.
It would not be difficult to trace the development of other
details of the ornament in the same way, but enough has been
said to show the absurdity of placing much reliance on the
character of the ornament in such a genus as Morio as a crileriou
for differentiating species, or even so-called "varieties." The
facts given suggest that if the growth of the shell in this and
some allied genera be studied in detail, it will be seen that
the difference observable in many so-called species are mere
individual characters, brought about by the suppression of bold
features, or the lack of accentuation in the adult of certain
characters which made their appearance at a much earlier stage.
lu judging the relative value of ornament in this connection, it
would seem that the most reliable differentiations are to be made
out in the younger stages of growth. Professor Tate is to be
congratulated in the moderation displayed in estimating the
number of species of Morio in the older Tertiary of Australia ;
contrast the work of Professor Sacco,' of Turin, in describing the
Cassidid^ of the Piedmont Tertiarv.

This is the largest known species of Cyprcea, living or fossil.
It is much inflated dorsally, base flattened ; inner margin smooth
within, flattened near the anterior canal, which is deep, narrow,
elongate, and projects upwards ; outer margin tumid, furnished
with nine or ten obsolete obtuse teeth near the anterior end, and
a few also near the posterior extremity ; posterior canal obliquely
truncate, bent upwards, and adherent to the spire.
This is by no means a typical Erosaria, the inner margin not
being dentate or plicate; but Sir E. M'Coy states' that under
certain circumstances, "faint indications of teeth may be detected";
in other respects, and in the broad sense, it conforms fairly well to
that subgenus. It is allied to Gisortia, Jousseaume, which, how-
ever, is t3pically largely tuberculate or keeled on the surface.

This large species is characterized by its solidity, the narrowness
of the aperture, grooved and ridged on either side, the grooves on
the columellar border extending well over the surface outwardly.
The shell is globose, smooth, furnished with solid, broad, flattened
extensions posteriorly, through which the short posterior canal
is cut ; anterior canal sharply bent towards the dorsal surface,
and flanged by thick, flattened callosities.
The short, very wide, truncate posterior extension, and the
prolongation posteriorly of the inner margin of the aperture,
which rises above the level of the callosity on the opposite side,
are distinctive. The enormous grooves on the columellar border
are not characteristic of Erosaria, in which it is here placed, but
in other respects it recalls that subgenus.

This is one of the most striking shells found in the Australian
Tertiary ; it is prolonged, and channelled both anteriorly and
posteriorly, and in these features bears a certain resemblance to
Amphiperas, Gronovius. The form of the spire, which is depressed,
is barely visible through the thin deposit of callous enamel with
"which it is covered ; the anterior prolongation has two large
irregular, obtuse tubercles of a compound character on the dorsal
surface, and is bordered by broad callous extensions of the ventral
surface. These features, together with long, deep sulcations cut
in the ventral surface and extending over the inner margin, which
take the place of crenulations (and, in fact, produce the effect of
a number of bold ridges), serve to readily distinguish this species
from its congeners. It has a general subgeneric resemblance to
C. umhilicata, Sowerby, which, as Professor Tate' points out, falls
into Umbilia, Jousseaume, in which subgenus it is here included,
though it is not typical, and may by some authors be regarded as
furnishing material for a new section of Cyprcea.

This species is closely allied to C. eximia, but is not so elougate,
the body-whorl being much more inflated, whilst the posterior
third of the aperture is strongly curved to the left. Another
point of difference is the mode of development of the columellar
lirae or sulcations : in C. eximia these are typically very close
together, and extend over a large portion of the ventral surface
of the body- whorl, especially towards the anterior ; whilst in
C sphmrodoma they are more like ridges, are shorter, broader,
farther apart, fewer in number, and do not extend over such
a wide area.
This species forms a connecting link between C. eximia and the
living C. umhilicata, Sowerby, as the author indicates.

Distinguished by its immense size (for the genus), it is more
globose, and has more distant ridges than has T. australis ; the
young closely resemble T. europcea, from which they can only be
separated with difficulty, the principal differentiating characters
being a more pronounced dorsal furrow, a prominently thickened
lip, and obscurely traceable spire-whorls. Professor Tate states
that dwarfed examples differ from T. europma by much the same
characters as the species does from T. australis, but that is hardly
borne out on comparison with a number of specimens of the
European species referred to. T. minima. Professor Tate says, is
an early stage of growth of T. avellanoides.

The similarity of the animal of Erato, including its radula, to
Trivia precludes the possibility of classifying the genus with the
Maeginellid^, as is frequently done by authors. As Dr. Paul

Marginella from the method of development of the columellar
plications.

This species is characterized by its columella ending anteriorly
in a strong spiral plait, in having a moderately wide aperture,
and by the thickening of the outer margin being squarely
shouldered behind. In shape it is globose-pyriform, and the
spire in the adult is so short that it does not rise above the level
of the curved posterior notch of the aperture.
As Professor Tate remarks {op. supra cit.), its "terminal spiral
plait on the columella, running out to form the left margin of
a slightly efEuse canal," is not characteristic of the genus. "The
denticles on the two margins appear when the adult stage is
reached, but the columella-plait belongs to all ages." Compared
with Marginella edentula, Tate, it is less inflated, and has not
such a convex columella.

Family STROMBID^.
Genus STROMBUS, Linnteus.
[Syst. Nat. ed. 10, 1758, p. 742.]
Shell ovoid, tuberculose or spinose, solid ; spire with several
whorls; aperture elongate, obliquely truncated and channelled
anteriorly, canaliculate posteriorly ; outer margin dilated, usually
thick, often produced behind, sinuate and sometimes channelled in
front ; columellar border simple, enamelled.
The following species is selected by Lamarck h —

> Mem. Soc. Hist. Nat. Paris, 1799, p. 72.
217
Strombus denticostatus, sp. nov.
[Plate VI. Fig. 8.]
Shell elongate ; whorls eight in number, those of the spire
longitudinally costate in the earlier stages, the costae there being
numerous, and extending almost from suture to suture ; in sub-
sequent stages these are modified, being much contracted, and
becoming dentate at the periphery ; on the body-whorl the costse
have shrunk, and are represented by immense, dentate, very
distant tubercles ; the other ornament of the spire consists
essentially of closely-set spiral lineations, which are broken up
into wavy undulations on the body-whorl of the adult by the
crossing of the lines of growth ; the outer margin is expanded and
wing-like, extending as a broad wide lobe posteriorly, rounded at
the extremity, and joining the spire at the posterior suture of the
penultimate whorl ; this aliform expansion tapers towards the
front by a graceful curve, the shell in that region becoming much
narrower in consequence ; the exterior aspect of the wing shows
that the spiral lineations become bolder and spi'ead out until they
attain the margin ; in particular, a bold keel fortifies the prolonged
lobe alluded to, whilst the growth-lines become prominent, almost
rugose ; anterior canal truncate.
It is unfortunate that the only example of this ornate species
in the Museum collection is an impression in limestone of the
back of the shell ; but, as will be seen from the figure (Plate VI.
Fig. 8), which is drawn from a plaster cast, the impression is very
perfect, and it seemed desirable to place this distinctive species on
record.

In proposing the name Pelicaria, Dr. Gray gives a very brief
description, and quotes only one species, which must, therefore,
be regarded as the type of the genus. It is evident, however,
that the description does not refer to that species, and the specific
references serve to accentuate the fact. Now, the type species
referred to is Pelicaria vermis (misquoted as P. vernis), which is
admittedly a Struthiolaria. Pelicaria must, in consequence, fall in
synonymy with that genus.

The ornament of the whorls of this well-known species is very
variable, though the contour is fairly constant ; the spiral threads
are sometimes very close and regularly spaced, more often at
irregular intervals, and occasionally far apart in bands of two and
three ; the prominent angle at the shoulder may be faintly,
distantly tuberculose, or the tubercles may attain to a great size.
The extent of the callosity covering the inner margin of the
aperture is also variable, but it is always thickest posteriorly,
where it spreads over part of the penultimate whorl, and anteriorly
on the front half of the columella.

The mode of growth of the shell of this species is very
remarkable. Unfortunately the protoconch is not preserved in
any of the specimens in the Museum collection ; the whorls which
immediately succeed, and which, presumably, constitute the brephic
stage, are boldly spirally lineate, each of the small whorls having
from six to seven lineations ; with growth, longitudinal striations
make their appearance, and these eventually give rise to small
nodulations on crossing the spiral lines, the surface of the shell
at about the commencement of the neanic stage being cancellate,
with the exception of a broad, sloping area surrounding the suture
posteriorly, which continues smooth and bears three or four spiral
cords with smaller lineations between ; the growth of the neanic
stage was evidently very vigorous, longitudinal costte are developed
on the anterior half of the whorls, and the nodulations at the
periphery become fewer in number but progressively larger until
' TuAoj ' callosity.'
CERiTHrcrsi. 223
they form large dentate tubercles, the ornament towards the close
of that stage being typically fusoid. Then a revolution was
effected by the commencement of the deposition of a thick coating
of enamel, all ornament being covered up, the posterior prolongation
of the enamel hiding the suture, and being flattened and fixed to
the preceding whorl ; with growth, the callosity becomes broadly
and deeply canaliculate, a feature which continues to the ephebic
stage. The body-whorl of the adult is entirely covered with
enamel, and it would appear that the large peripheral tubercles
are no longer developed, as they are not traceable through the
enamel, which is sinuously corrugated by growth-lines and bears
a few spiral threads, in which last-mentioned feature we seem to
see a recurrence to a former state. The callous enamel spreads
over the whole of the body-whorl and the anterior half of the
penultimate whorl, in the adult. Columella thickly covered ;
outer margin sinuous.

vol. xvii. pt. 1, p. 222.
Shell tapering, about twenty-four narrow, convex whorls ;
protoconch composed of four smooth turns, the earliest portion
slightly inflated, and the later turns being medially, spirally
carinate ; in the brephic stage the whorls are closely spirally
sulcate, and these are broken up irregularly by the undulations
of growth ; the undulations, being of variable breadth, have, at first,
the aspect of varices ; beyond the brephic stage (and this is very
remarkable) the irregular longitudinal ribs as a rule become almost
obsolete, several whorls being practically smooth, or broadly
longitudinally undulating, the spiral sulci being well developed
with several smaller striae between. Then, as the animal
approached the ephebic stage, there was a recurrence to the
longitudinally costate condition which characterized the brephic
stage, and these costae become very large and prominent at
maturity. Subsequently the ornament undergoes rapid trans-
formation. With declining powers, ushering in conditions of the
gerontic stage, the conspicuous costae alluded to drop to insignifi-
cance and die out, the surface of the whorls bearing only the
spiral cords and lineations and the undulating lines of growth.
As a final effort, an enormous variciform elevation was then thrown
up, much larger and more prominent than any of the longitudinal
ornament which preceded it ; after which, permanent senile
conditions having been attained, the surface of the body-whorl
becomes smooth again, only being interrupted by the lines and
slight corrugations of growth and the abnormal development of
two or three spiral cords which persist to the end. The aperture

channelled, outer margin smooth, slightly callous, and spread
outwardly ; inner margin concave, callous, and columella twisted ;
anterior canal short, bent at an angle of about 45° from the
axial line.

Q
226 CEEITHIUM.
The circumstance that the aperture is not perfect in the
specimens described by Professor Tate has, naturally, rendered it
difficult to state the generic position of this species. The
specimens in the Museum collection are not perfect in that respect,
but the present writer assigns the species to Cerithium rather than
to Potamides on account of its close resemblance to G. semicostatum,
Deshayes, of the Lower Eocene of North-West Europe. It is
always difficult to discriminate between the two genera mentioned
in the fossil state, but, typically, Cerithium is a marine organism,
whilst Potamides inhabits brackish and fresh waters. The beds at
Table Cape are certainly of marine origin, and that lends support
to the view that the present species is a Cerithium. As before men-
tioned, however, the circumstance that C. semicostatum, Deshayes,
of the European Eocene is undoubtedly a Cerithium * (of the
subgenus Vulgocerithium '), is one of the chief reasons for the
present classification of the Tasmanian form.
On being assigned to Cerithium, the specific name proposed by
Professor Tate is preoccupied by C. semicostatum, Deshayes; the
species is now named in honour of Mr. G. B. Pritchard, a well-
known worker on the Table Cape beds.

In shape it resembles Melania, with which genus it has been
commonly confounded ; but the characteristic A-aricose whorls and
the phenomena of the aperture indicate closer affinities with the
Cekithiid^, in which family the late Dr. Paul Fischer' and
M. Cossmann^ have classified it.

Shell solid, turriculate ; whorls about ten in number, excluding
protoconch (which is not preserved in the specimens in the Museum
collection), the fine longitudinal and spiral ornament is described
in detail by its author ; suture cut in ; aperture oblique, ovate,
angular behind, and slightly depressed in front ; outer margin
thin ; inner margin callous, a thick, obtuse ridge bordering the
posterior channel; columella with a single plication or fold,
accentuated in the adult, the attendant callosity spreading over
the anterior portion up to the sinuosity in the front of the aperture.
The costfe of the whorls are more slender and numerous than
in the living D. melanoides, Reeve, and the callosity spreading
behind the front of the columella is more sharply defined than in
the recent shell, with which it presents many striking points of
resemblance. Compared with D. costellatum, Lamarck, of the Hamp-
shire and Paris basins, amongst other things it is more solid,
broader, has less convex whorls, the longitudinal ribs are smaller
and closer together, whilst the large ridge and thick callous inner
margin are highly characteristic.

The first two or three whorls are slightly adherent, but the
shell becomes rapidly uncoiled ; the fissure is very long, prominent,
wide, and the sides are irregularly cut ; the lines of growth form
corrugations and small cracks, and are somewhat scaly ; spiral
lineations very faint except on the under-surface, where they are

This common species is liable to great variation, each distant
locality seeming to possess a dominant form. Professor Tate
describes it as follows: — "Shell pyramidally turreted, apical angle
about 15°. "Whorls twelve to fourteen, flatfish, medially depressed,
and acutely elevated at about the anterior-fourth ; suture thread-
like, or somewhat grooved ; apical whorls two, very small,
globulose ; first spire-whorls rapidly enlarging, 1-3 carinate.
Surface ornamented by about twenty-four spiral threads, with or
without smaller intermediary ones, crossed by close-set striae, the
latter on the anterior whorls thiuly squamose. Last whorl bluntly
truncated on the periphery ; base with spiral threads and trans-
verse strife on the upper part of the whorl. Aperture quadrately
oval, continuous ; outer lip with a deepish subtriangular median
sinus. The sectional outline of the whorls varies from flat or
slightly concave to somewhat quadrate, and correspondingly in
the depth of the suture ; the ante-medial keel is sometimes
obsolete, but the medial depression is always present."
The last-mentioned feature and the numerous spiral lineations
are, perhaps, the chief difl'erentiating characters.

the absence of very conspicuous spiral ornament ; there is, however,
a slightly elevated bisected ridge bordering the suture on the

lines of growth are deeply sinuous and numerous, but are not very
striking.

Typical forms of this species possess but one prominent keel,
whilst those of T. tristira, Tate, have three which are equal in
size ; and that appears to be the chief point of difference between
the two species. Occasionally, however, forms of T. conspicahilu
are found possessing two minor keels, behind the prominent
one, and as these develop in size the shells closely approximate
T. tristira as having three keels, but they are of unequal size. Its
author reluctantly considered T. conspicabilis as distinct. It might
have been advisable to regard it as synonymous with T. tristira,
but not having seen actual specimens of the latter, the present
writer hesitates to definitely make the alteration. Variation in
the number of spii-al keels is well exhibited by the Miocene
and Pliocene T. triplicata, Brocchi, of Europe, with which the
Australian species mentioned have considerable affinity. In the
Tortonian beds of Stazzano, in Piedmont, for example, one can
find T. triplicata with practically every variation from one
prominent spiral keel to thi'ee well-formed keels; and parallel
cases could be cited from other localities in reference to other
species. The number of keels is certainly not a good differentiating
character with Turritella.

This variable species may be distinguished by its slender
lanceolate form, by the large number of whorls, amounting to
twenty in typical forms of the adult, and by their flatness.
Commonly there are from fifteen to twenty spiral lines of unequal
size, the larger ones forming lirse or carinae, which latter may be
from two to five in number, the largest bordering the suture
anteriorly. The variation consists principally in the mode of
development of the spiral ornament and the consequent change
in shape of the whorls.
It is closely related to T. acuta, Tenison-Woods [non Mayer),
a species living in South Australia and Tasmania, but the fossil is
relatively narrower, and the spiral lineations and carinae are more
numerous.

Shell pyramidal, spire acute ; whorls flat, furnished with three
prominent, unequal, spiral carinae, and distant spiral striae ; lines
of growth conspicuous, deeply sinuated, producing rugosity, and
granulating the medial keel; suture incised; aperture (according
to the author of the species) subquadrate, margins united by a
somewhat thick callus, which extends over much of the flattened
forepart of the shell; columella arched; outer margin somewhat
flatly compressed, and deeply and broadly sinuated. Its pyramidal
shape, the granulose median keel, and the deep sinus, serve to
readily distinguish this from T. warlurtoni and T. conspieahilis.

synonymity of T. sturtii with T. warburtoni at some length. The
chief difterences noticeable in the two so-called species are mere
details of ornament of the whorls, which certainly are not
important enough to warrant specific separation in such variable
forms as we are now dealing with.

Shell small ; characterized by a very promiaent obtuse spiral
carina near the suture on the anterior portion of the spire-whoils,
between, which and the suture is a small spiral thread, the space
between the two developing into a sulcus on the periphery of
the body -whorl in the adult. Behind the carina are several more
or less obsolete spiral striae, one of which, towards the middle of
the whorls, is usually more accentuated than the others ; an
■ obscure ridge borders the suture posteriorly. Several spiral
lineations occur near the anterior extremity of the body-whorl.
Lines of growth sinuous, cut in towards the middle of the whorls.

Distinguished by its flat whorls, the body-whorl in the majority
of adult specimens being sharply keeled, and having a broad,
flat area anteriorly ; a spirally striated keel borders the suture,
and there are several undulating spiral threads of irregular sizes,
some being very prominent.
It recalls young specimens of the common T. earinifera,
Deshayes, of the European Eucene. A remarkable feature both

in some living and extinct forms of the adult of this variable
species is the diminishing importance of the prominent spiral
carina and the corresponding roundness of the periphery of the
body-whorl, and slight convexity of the usually flat area of the
forepart of that whorl. These features may possibly be charac-
teristic of the gerontic stage, but the adult specimens at the
writer's disposal are not numerous enough to enable him to
satisfactorily determine that point.

gutter following the peripheral keel, with several simple, small
lineations crossed by closely-set undulating lines of growth ;
inside this plain depressed portion, towards the umbilicus, are
seven rows of spiral granulations, the first one (outside) consisting
of minute elongate ridge-like elevations, the longer axis pointing
towards the centre ; then follows the second row, in which the
granulations or ridges are of the same shape but much larger ; ia
the third row the granules are a little smaller and farther apart;
in the fourth row the granules are much larger ; the fifth row
has very minute granules, the sixth and seventh progressively
larger, the largest of all bordering the umbilicus ; the umbilicus

This differs from Solarium principally in having rounded whorls
instead of being sharply keeled at the periphery ; the whorls are
granulated and spirally lineate ; aperture almost circular, lip
simple, umbilicus large. Typically the spire is much elevated,
and even turbinate ; but several species have a depressed spire,
and the shell is then planorboid. It would appear that, in
some cases {e.g. the living S. variegata, Gmelin) the elevation or
depression of the spire is only a varietal character.
The term Torinia must fall in synonymy, as Heliacus was
proposed before the former was established on a firm basis, as
above indicated.

he first established Calyptropsis ; but the latter work was not, in
reality, published until early in the year 1894, whereas the Trans.
Roy. Soc. South Aust. vol. xvii. pt. 2, above quoted, was published
in Dec. 1893, thus taking priority. The following species is here
selected as the type of the subgenus : —

XENOPHOEA. 253
This common species is distinguished by its compressed form
and lateral apex; the "whorls rapidly enlarge, growth-lines
corrugating the surface ; internal plate moderately large, part of
the edge slightly overhanging the umbilicus.
Some of the specimens mentioned hereunder, which are in the
state of casts only, are doubtfully referred to this species.

are agglutinated to, or imbedded in, the upper surface of the shell,
sometimes completely hiding it from view ; last whorl compressed,

Shell umbilic;ite, foreign substances being agglutinated only in
the neighbourhood of the suture ; periphery of the last whorl
much prolonged, tectiform.
Ti/pe. — Xenophora indica, Gmelin.
Xenophora (Tugurium) tatei, sp. nov.
[Plate Til. Figs. 7a-J.]
Shell trochiform, with moderately elevated spire ; whorls broad,
seven in number, very small to commence with, but rapidly
increasing in size ; the surface of the whorls, as seen between the
foreign fragments adhering (mostly in the vicinity of the suture),
is irregularly, obliquely undulating and ornamented by closely-set
wavy, roughly spiral lineations, which are crossed by more or less
conspicuous growth-lines ; the keel at the periphery of the last
whorl is sharp and undulating ; the under surface is concave, the
depression being most marked near the keel, curved lines of growth
are conspicuous ; aperture subquadrate; outer margin thin, strongly
curved, deeply concave, and much produced at the margin owing
to the prolongation of the last whorl in that region ; inner margin
slightly thickened, the thin callosity spreading over as a plate or
lining on the inner posterior surface of the aperture ; umbilicus
funnel-shaped, small.
Compared with the European Tertiary X agglutinans, Lamarck,
with which it is allied, the Australian species has a relatively
higher spire, the whorls are not so flat, and the under surface is
narrower; X agglutinam has a much larger umbilicus, whilst its
outer margin is not so deeply concave, nor so greatly produced;
the ornament of the whorls is different. On the other hand,
X. tatei is broader than the European Eocene X conjusa, Deshayes,
whilst the latter is not umbilicate.

Family NATICIDiE.
Genus NATICA, Scopoli.
[Introd. Hist. Nat. 1777, p. 392.]
Shell ovate, globose, shining, solid, usually smooth ; umbilicate ;
spire short ; aperture entire ; columellar border thick, subvertical ;
outer margin thin, not sinuous.
Kecent authors,' following Lamarck,- regard N. canrena, Linnaeus,
as the type of Natica. Adanson^ was the first to propose Natica,
but liis work must be ignored, according to the usual rules of
nomenclature adopted in this country. In introducing Adanson's
name into binomial nomenclature Scopoli cited four examples,
neither of which includes N. canrena, which cannot, therefore, be
cited as the type. Another reason (if one were requii-ed) for not
accepting that species is, that N. canrena of Linuteus was a
compound of several species, as is generally recognized. Of the
four examples cited by Scopoli two are of Natica, as at present
restricted, and it will prevent confusion if one of them be selected
as the type.
The chief divisions of the IS'aticid^, being based for the most
part on the character of the operculum, can only be doubtfully
recognized in fossil forms.

Shell globose ; spire somewhat elevated, suture clear, accom-
panied by a depression ; aperture broad, rounded in front, angulate
behind ; outer margin thin ; inner margin covered partially by
enamel, but there is no posterior callosity ; umbilicus semilunate,
funiculus broad, the outer portion conterminous with the columellar
border, slightly overhanging, defined in front by a narrow sulcus.
Immature specimens resemble N. caillati, Deshayes, of the
European Eocene ; but the aperture of the Australian species is
broader, whilst the excavation behind the funiculus is charac-
teristic, and the spire is not so much elevated.

The shell of this species is flattened, and, in consequence, is
not so globose as JSf. hamiltonensis ; neither is the spire elevated.
It is very closely allied to the European Eocene N. noes,
D'Orbigny, but the spire of the latter is more salient, its
funiculus is not so much dilated, and the suture is cut in, whereas
in iV. subnoce the suture is almost concealed.

1893. Natica [Ncvcrifa] varians, Tate, Trans. Roy. Soc. South Aust.
vol. xvii. pt. 2, p. 322, pi. vi. figs. 2, 9 {non Dujardin).
Shell large, solid, narrow; spire very short, body -whorl
enveloping, few spiral striae ; aperture oblique ; outer margin
oblique ; inner margin extremely callous posteriorly ; umbilicus
large, funiculus broad, terminating on the columella in a moderatf-
sized callosity, bounded posteriorly by a deep, striated sulcus,
anteriorly by an undulating groove.
The specific name given by Professor Tate is now changed, as it
is preoccupied by Dujardin, ]V. varians being a common form in
the Miocene of the Touraine, and having nothing in common with
the Australian species. The name here proposed is derived from
Cunningham, in Gippsland, one of the localities where the species
has been found.
The umbilicus in Neverita is practically filled, or is nearly
covered over, by a funicular callosity, the outside portion of which
is conterminous with the columellar border ; the shell, also, is
depressed. These characters are not possessed by N. cunningham-
ensis, as will be observed from what has already been said. The
present species does not differ essentially from Natica, sensu stricto,
except perhaps in having the posterior callosity, which does not
seem to be of much systematic value ; other species included by
Professor Tate in Neverita are here placed under Natica for
similar reasons.

The type of Naticina, Guilding, as specified by that author,'
is i\^. lactea, Guilding, and as this species falls within the earlier
Polinices, Montfort, Naticina, Guilding, is synonymous with
Polinices (Mamma), as pointed out by American authors.''
JV. catena, Da Costa, regarded by some authors' as the type of
Naticina, does not fall within that subgenus. The Naticina of
Gray refers to naticiform Sigareti, and is in no sense applicable to
the moUusca falling under Naticina, as defined by Guilding. The
majority of the fossil species usually included under Naticina
may be referred to Limatia when that term is liberally interpreted.

Shell naticiform ; umbilicus without a funiculus, open or closed
by callosity; aperture large; outer margin sinuous, produced at
the middle ; umbilical region limited by a spiral rib or limb more
or less developed ; columellar border curved, typically S-shaped.
The writer cannot find that the name Ampullina (so commonly
applied to fossil naticiform shells of the Tertiary of North-Western
Europe) was properly established before Desor and Agassiz had
proposed the term Euspira. Defrance, who is generally credited
with having introduced Ampullina {op. supra cit.) does so in the
vernacular as "Ampulline," and even if that could be admitted
as proper establishment we are left in difficulty as to the meaning
of the term. "Ampulline" is not diagnosed, nor is it stated in
what way we are to distinguish it from Ampullaria as described by
Defrance.
265
Deshayes {op. supra cit.) mentions AmpulUna as having been
suggested by Lamarck, but never published by him ; also, that the
latter had subsequently abandoned the terra. But Deshayes does
not quote any species illustrating Lamarck's proposal, and we are
thus left in doubt as to what AmpuUina really was.
In 1822 Eowdich' divided Ampullaria into two parts, one of
■which he (jailed AmpulUna. He gives a figure as representing it,"
but neither in the text nor in the explanation of the plate does he
mention a single species in connection with it, and AmpulUna is
not there diagnosed nor established.
In 1830 Blainville {op. supra cit.) used the term AmpulUna in
another connection, so that after that date it was not available for
the molluscs indicated by Deshayes and as exemplified by Natica
sigaretina.
In 1837 Desor and Agassiz {op. supra cit.) suggested the term
Euspira, comprising in it such species as Natica glaucinoides,
Sowerby {nan Deshayes), iV^. depressa, Sowerby, Ampullaria patula,
Lamarck, A. acuta, Lamarck, A. sigaretina, Lamarck, A. ambula-
crum, Sowerby, etc., etc. French authors ' have interpreted
Euspira through the medium of E. canaliculata, Morris and
Lycett.* That species cannot possibly be regarded as the type of
the genus, however, as it was not mentioned by Desor and
Agassiz when they founded Euspira — the species was not even
denominated at that period. Euspira as delimited by the last-
mentioned authors includes species of Natica ; to prevent miscon-
ception the following well-known species is here selected as the
type, from amongst those mentioned by the authors of the genus.
Tgpe. — Ampullaria sigaretina, Lamarck.
Subgenus AMPULLOSPIRA, nom. mut.
Euspira, Cossmann, etc. (wow Desor and Agassiz).

The specimens in the Museum are not in good preservation, but
Professor Tate, comparing A. effusa with the European Eocene
A. acuminata, Lamarck, and A. levesquei, D'Orbigny, states that
"It agrees with them in the elevated and canaliculate spire, but
is readily distinguished by its regular spire (not subulate),
effusively dilated aperture, and elegant sculpture ; from A.
acuminafa, it is further removed by being umhilicated, but
resembles A. levesquei in its simple umbilicus." The surface is
ornamented by closely-set spiral striae broken up by slightly
curved incised lines.

Shell solid, turreted ; whorls to the number of fourteen or
fifteen, spirally bicarinate in the earlier stages of growth, but
becoming markedly tricarinate as the ephebic stage is approached ;
these carinae are rounded and equidistant, and are interrupted by
the crossing of longitudinal scalariform plates ; the front of the

The general aspect of this shell is rather that of MathiUia,
Semper. Neither of the examples in the Museum collection have
the protoconch preserved, but it would appear from Professor
Tate's description {op. cit.) of the ' apex,' which he remarks is
' acute,' that the protoconch is not heterostroph, so that the

This well-known species differs from T. vtridis in being broader,
less granose, by having a deeply-cut suture, the base is less concave,
and by the absence of small tubercles on the inner margin of the
aperture. It is specially characterized by the nature of the false
umbilicus, which is plain and deep ; by the possession of a broad
simple surface on and near the columellar border ; by a rim and
tooth-like thickening on the posterior of the inner margin ; and
by the comparatively flat base, which is spirally granulate.

It has been customary for many years past for authors to
regard as genera and subgenera forms having the general characters
of Dentaltum (^sensu stricto), but differing from it in possessing
peculiar phenomena at the posterior orifice, and in the presence
or absence of sculpture externally. Thus Entalis, Gray, was
DENTALrUM. 291
made to include those forms having a short, broad fissure at
the posterior extremity in addition to being practically smooth.
In Fitntiaria, Stoliczka,' the shell is also smooth, but the posterior
extremity is furnished with a long linear slit. Lcevidentalium,
Cossmann,- has a smooth surface, marked only by faint lines of
growth ; it has no posterior fissure, and is oval in section. In
Schizodentalium, G. B. Sowerby,^ there are a ni;mber of small
longitudinal slits in line with each other in the place usually
occupied by the long posterior fissure, when that is present.
In other words, the longitudinal slit is bridged over here and
there. Lohantale, Cossmann,* appears to be very different to
other allies of Be.ntalium in being compressed, smooth, and carrying
two lateral ribs in the interior of the shell.
Now, the type of the genus Dentalmm is described by authors
as having a truncated posterior orifice, without a notch or slit. In
a revision of the British Eocene Scaphopoda, ilr. R. Bullen
Newton, r.Gr.S., and the present writer^ agreed with those authors
after examining typical specimens in the British Museum, and
allowed the absence of a notch to mark the difference between
it and Entails, Gray. The latter name being preoccupied,
us will be noticed in the synonymy above given, we proposed
a new one, Entaliopsis. Subsequently, however, we noted some
undoubted specimens of the type species in the British Museum
which were furnished with a small but well-marked notch. It
became apparent that iudividuals of that species may or may
not possess a notch. The question then arose as to whether
the absence of a notch was due to mutilation of tlie shell, or
was brought about by the repairs continually carried out by
the animal. In this connection the observations of Professor Dall
may be of service. He remarks' that "species (of Bentalium)
with very thin shells usually live buried in soft mud, which
measurably protects them, but others with heavy shells appear
to be more versatile ; at all events, if the small end of the

shell is acciflentally broken off, the animal can repair it, and
in species which have a simply tubular mantle and a thick
shell the repairs take the shape of a small tube projecting from
the blunt end of the large one, as it is impossible for the mantle
to secrete a shell which is as large and thick as the original
at the point of truncation." From this it is obvious that in
such a thick shell as is possessed by the typical species of
Dentalimn, a small portion of the posterior orifice having been,
by accident, broken off, it would not be within the animal's
power to rehabilitate it in its entirety.
On the other hand, the possibility of the small notches on the
typical specimens having been produced, not by any modification
in the mantle of the animal, but by erosion, should be considered.
It is well known that erosion, especially in specimens from
deep water, modifies and sometimes imitates such slits. As
Professor Dall observes,' there "seems to be a peculiarity of
some kind in the external prismatic layer of Dentalium, which
lends itself to the propagation of erosion in longitudinal lines
very much more effectively than at right angles to such lines."
In regard to the systematic value to be attached to the notch,
slit, or fissure, it may be remarked that these variations depend
upon the shape of the edge of the mantle, which is an extremely
contractile membrane, capable of secreting shelly matter. When
the shell is quite perfect, the posterior end reflects the form
of the membrane which secreted it. There can be no doubt
whatever that the length of the slit varies in individuals of
the same species, apart from any appearance produced by erosion.
It cannot, however, be asserted that a mere notch could by
individual peculiarity be elongated to such a length as obtains
in typical specimens of Fustiaria. So that it may now be
admitted that the presence or absence or length (within certain
limits) of the slit is not of generic, nor even subgeneric importance,
but it may with other characters be of specific value. In any
case it seems desirable that Entaliopsis { = Entalis) should be
regarded as a synonym of Dentalium ; the sole difference between
them, as now shown, being merely one of external ornament.
In this Mr. E. BuUen IN'ewton fully concurs with the present
writer.

Shell small, slightly curved, furnished with seven or eight bold
longitudinal ribs, between which are several minute longitudinal
striae crossed by conspicuous lines of growth.
This species was, apparently, without a posterior fissure, and
would be regarded as a typical Dentalium. Although small, the
shell is solid, and forms no exception to the rule that solidarity
is accompanied by frequent repairs to the shell. When broken,
it will be seen that the hard internal layer tends to form a tube,
which would probably lead some authors to classify it with the
genus Antale ; but, as previously remarked, such tube is of little
or no systematic value.

The posterior fissure is a triangular notch, the sides of which
are slightly reflected outwardly. It may be easily differentiated

Genus CADULUS, Philippi.
[Enum. Moll. Sicilioe, vol. ii. 1844, p. 209.]
The following species is referred to Cadulus with all reserve.
It is practically impossible to distinguish between that genus
and Siphonodentalium with the shell alone. Authors have placed
some reliance on the nature of the margin of the posterior orifice ;
but Dall has shown ' that the anal orifice of the shell may
be waved or simple on its margin in different specimens of the
same species ; and Fischer has called attention ^ to the fact
that those which have the margin interrupted by several slits,
or notches, exhibit considerable variation in the details. However,
if it is admitted that on the whole the shell of Cadulus should
be short, inflated medially, and thickened internally towards the
posterior oi-ifice, which is crenulated, the Australian species about
to be described may be assigned to that genus.

It is impossible to recognize this species from the caricature
given on the plate above referred to ; but Professor Tate describes
it so nainutely that the figure may almost be dispensed with. He
remarks that the shell is "long, narrow, slightly bent; slightly
swollen at a little nearer the anterior than the posterior end, more
conspicuously so on the convex curve, which is a little nearer to
the posterior end than is the bulging on the concave curve.
Anterior to the inflation the tube is slightly laterally compressed.
The mouth is slightly oblique, oval, with a thin and sharp edge ;
the posterior opening is round, thickened within, and bevelled to
a sharp edge, inconspicuously mucronately produced on the convex
side, corresponding with a faint internal rib, and slightly insinuated
laterally. Surface smooth, polished, microscopically concentrically
striated, and with faint indications of opaque transverse bands."

The only specimen in the Museum collection which approxi-

Professor Tate, that the writer has some diffidence in assigning
it to that species. But in other respects it agrees so closely with
the diagno^^is given by the author, and the figure accompanyiijg
it, that for the present it may be regarded as a local variation,
characterized chiefly by the immense size of the shell. The
specimen in ([lU'stion is moderately excavated interiorly, whilst on

[Mem. Soc. Geol. France, 2^ ser. t. iii. pt. 2, 1850, p. 470.]
Shell inequivalve, suborbicular, equilateral, flat, adhering by one
of the valves ; ligament internal, median, lodged in an elongated
groove ; no cardinal teeth ; interior of the valves typically showing
a linear row of denticles parallel to the margin of the shell.
After discussing the systematic position of the genus. Professor
Tate remarks that the two new Australian species which he assigns
to Limy a "have the general aspect of Plicatula rather than of
Ostrea ; whilst the two diverging cardinal ridges make an approach
to Placuna, though functionally different." That author is mistaken,
however, in supposing that Bimya was founded on a shell from the
Parisian Eocene ; it came from Bos d'Arros, in the south of France.

Family PECTINID^.
Genus PECTEN, Miiller.
[Zool. Dan. Prodr. 1776, pp. xsxi.-248.]
Chlamys, auct. (See below.)
Shell suborbicular, auriculate, ornamented by radiating costae ;
right valve typically convex, inflated and produced in the umbonal
region, which curves inwards ; left valve typically flat and smaller
than the other, but in certain sections of the genus it is subequal
and convex ; cardinal liue straight ; ligamental pit commonly
triangular, internal.
This genus has been divided into a number of sections, the
largest of which, Chlaixys, included by authors as a separate genus,
certainly possesses some title to distinction, though the difi'erences
consist, principally, in its having the wing-like expansions of
unequal size, and especially in that both the valves are convex.
But the name is inadmissible: it was first proposed by Polten
in his Catalogue of the " Museum BoUenianum," 1798, which work
is not accepted by British malacologists, following the accepted
rules of nomenclature. Before Bolten's name was adopted the term
814
Chlamys was proposed for a genus of Coleoptera in 1801, and
cannot therefore be used for the mollusc.
There is no absolute synonym of Chlamys that could be employed,
but the writer is not inclined to suggest a new term, believing that
by a greater breadth of treatment than is now in vogue, one of the
numerous sectional names already in existence will ultimately
be applied to those Pectinid^ that have hitherto been called
Chlamys. The Australian forms here alluded to are therefore
retained in Pecten, for the present.

granular structure of the spaces between the costse, which also
bear a few obscure longitudinal lineations ; auriculae well developed.
The author compares it with the living South Australian
P. hifrons, Lamarck, from which it differs by the obliquity of
its valves, and in being broader ; the interior is plicated, but not
costated as in P. lifroyis.

Genus PSEUD AMTJSSIUM (Klein), H. and A. Adams.
[Gen. Eec. Moll. vol. ii. 1858, p. 653.]
Distinguished from its near ally Amussium by not having
radiating ribs on the interior of the shell ; whilst the auriculae
are unequal in size.
Bruguiere ^ is generally credited with having been the first to
adopt Klein's Pseudamussium {em.), but on reference to his work
it will be seen that he is merely dealing with Klein's method
of classification of the Mollusca, and that although he gives a brief
description he does not quote any species in connection therewith
so as to typify the genus. At a later date, in the same work,
Deshayes^ mentions Pseiidatnussium, but although he gives a
diagnosis and illustrates it by quoting some species, he remarks
that "this genus has not been adopted."
Messrs. H. and A. Adams appear to be the first to have actually
adopted it, though they quote a number of species some of which
are not typical of Pseudamussium as intended, apparently, by Klein.
The type of the genus, as selected by Stoliczka^ and as given below,
occurs in H. and A. Adams' list as a synonym, which, however,
is easily recognized.

Genus AMUSSIUM (Klein), Megerle von MiiUfeldt.
[Ges. Naturf. Fr. Berlin, Magazin, 1811, p. 59.]
Shell almost orbicular, depressed,. auriculse small, equal in size;
valves smooth on the exterior, but having radiating ribs in the
interior, which is the principal differentiating feature of the genus ;
ventral border not plicated.
Of the two species mentioned by Megerle von Muhlfeldt the
following is selected as the type of the genus.

1895. AniKssium zitteli, Tate and Dennant, id. vol. xix. pt. 1, p. 112.
Shell small, interior smooth, shining and furnished with from
nine to eleven costas which are truncated near the margin ; left
valve concentrically striated, auriculse unequal ; right valve striate-
reticulate, or ridged, but the exterior ornament is very variable.
Professor Tate,' in detailing this peculiarity, says that "the right
valve varies very much in respect of the number and thickness
of the radial and concentric threads ; usually the radial threads are
stouter than the raised concentric lines, but this form merges on
the one hand into a fenestrated ornament, and on the other to
one in which the radial ridges are very prominent and minutely
scaly." The posterior auricle of the right valve is larger than
the anterior ; it is triangular and cancellate.
It is allied to A. sqiiamula, Lamarck, of the Parisian Eocene, but
the latter is devoid of conspicuous reticulate ornament on the
exterior, and is relatively longer.

Shell pearly, less oblique than in Avicula, whilst the valves
are broader and almost equal in size ; posterior auricle short, not
separated by a sinus ; hinge teeth visible in the young, but not in
the adult.
It is unfortunate that the ■well-known Meleagrina, Lamarck,
should have to disappear in synonymy, as above indicated, but it
cannot be helped if we are to be consistent in putting the law of
priority in force. At least four names were suggested for this
genus before Lamarck's name of 1819. If objection be taken
to Patrick Browne's work, as he did not actually name a species
in connection with Margaritifera, but referred to plates and figures
in earlier works as indicating what he meant, then Unionium,
Link, is available, the type of which is, very clearly, Mytilus
margaritiferus, Linnaeus. But, seeing that Linnaeus ' had inter-
preted the plates and figures alluded to, we are not left in doubt
concerning the appellation of the shells represented, and the name
Margaritifera is, therefore, here adopted.

In general form this shell resembles V. deperdita, of the Eocene
of Europe, from which, however, it may be distinguished in being
relatively narrower and in having less divergent umbones. The

of the Parisian Eocene, is very close, but that it differs by the
large, straight ligamental pit.

Family ARCID^.
Genus ARCA, Linnaeus.
[Syst. Nat. ed. 10, 1758, p. 693.]
Shell commonly equivalve, subrhomboidal, ventricose, costulate
or cancellate ; borders of the valves either smooth or dentate ;
hinge straight, horizontal, furnished with very numerous, short
teeth ; umbones prominent, curved inwards, separated from each
other by a more or less broad area, which carries several liga-
mental striae or well-marked, narrow, linear grooves commonly
V-shaped ; impressions of the adductor muscles of the valves
331
subeqiial, the anterior being rounded, the posterior divided ;
impression of the posterior adductor of the byssus elongate and
situated near the cardinal line ; that of the anterior adductor of
the byssus small ; pallial line simple.
The genus has been much subdivided according to the character
of the external ornament, the shape of the shell, and the nature
of the ligament area.

In this small species the valves gape ventrally ; -whilst the
umbones are high and wide apart, and the few hinge teeth are
oblique. There is a characteristic depression from the umbo to
the ventral margin ; surface ornament bold, consisting of concentric
imbricating ridges and acute radial costae. The author remarks
that the " ornament varies in respect to the relative strength
of the radial ribs and concentric ridges, whilst in the other extreme
it consists of radial ribs variously thickened at the intersections
with the concentric lines." The inner margin of the valves is not
crenulated; hinge area broad, longitudinally lineated.
Judging from the obliquity of the hinge teeth and their increase
in size laterally, this species forms a connecting link between Area
(^sen-iu stricto) and the subgenus Barlatia.

Shell rliomboidal, though broader posteriorly, medially longi-
tudinally depressed, ventral margin sinuated ; hinge-line long,
straight ; external ornament consisting of bold, undulating
concentric lineations, crossed by longitudinal lines, which become
slightly swollen at the points of intersection, and have the
appearance of being broken up into short lengths.
The median depression is characteristic, and serves to distinguish
it from the young of A. celleporacea, to which it bears a super-
ficial resemblance ; another point of difference, on comparison
with that species, is the relatively larger reticulated area between
the obtuse keel and the superior border posteriorly in A. crustata.

Differs from A. consutilis in being slightly less tumid and
relatively longer ; the hinge-line is straighter and longer, and is
angulate at both ends. The ornament consists of closely-set
radiating costa), each rib of the posterior half being longitudinally

The shell of this species closely resembles that of B. simulans,
but that portion anterior to the umbones is relatively shorter, and
the latter are very broad and incurved ; perhaps the most striking
differences are the larger number of teeth on the hinge and the
greater distance between the umbo and the beginning of the ridge
which denotes the commencement of the anterior section of the
hinge-line ; the anterior margin is less rounded than in B. simulans,
and the ventral margin is usually more deeply sinuated.

None of the specimens in the Museum collection are well
enough preserved to enable the writer to identify with certainty
the New Zealand form with that from South America, and the
determination is chiefly based on the authority of Professor Hutton.
The shell is remarkable for its extreme tumidity, great breadth
of the area, and immense internal ridge, on which are the scars of
the posterior adductor of the valves.

Genus PECTUNCULUS, Lamarck.
[Mem. Soc. Hist. Nat. Paris, 1799, p. 87.]
This differs fi'om Cucullcea, in being orbicular, or suborbicular,
equivalve and almost equilateral ; the umbones are closer together,
and the area is, in consequence, narrower and relatively smaller.
The ligamental area, which is external, carries diverging grooves ;
cardinal border semicircular ; teeth prominent, strong, becoming
obliterated uuder the umbones as the gerontic stage is approached,
by the invasion of the ligamental area ; margins of the valves
crenulated.

Shell roundly trigonal, oblique ; surface faintly and closely
marked with radiating ribs and concentric striae and ridges ;
umbones acute, incurved; area conspicuous, broad, traversed by
divergent ligament grooves ; teeth large, oblique ; adductors of
the valves large, shell on the inside of each depressed, the edges
of the depressions bordering the scars and meeting the simple
pallial line.
It is closely allied to P. cor, Lamarck, and young specimens
of that are separated with difficulty from the present species.
P. cainozoicus, however, has a relatively larger hinge, the umbones
are more elevated and acute, and the depression on either side
of the adductor scars is characteristic.

There appears to be no conchological diiference between the
European and Australasian examples of this variable species.
Typically, the shell is not so oblique as L. helcheri; radial linea-
tions are barely perceptible (or absent) in many individuals. The
writer agrees with Professor Tate (o^. supra cit., 1886) that
L. zealandica, Hutton, is a synonym.

The specimens In the Museum coUectioa are all ironstone casts,
and, the hinge-line not being visible, the generic position of this
species is doubtful also. In his diagnosis Mr. Etheridge, jun.,
remarks: — "Our fossil approaches some of the flat forms of
Anodonta, and it is with these that it must be compared. The
more or less compressed valves, strong posterior angulation of the
dorsal margin, obliquely truncated posterior margin, and obliquely
rounded anterior margin, pending a knowledge of the dental
characters of the hinge, all point in this direction."

Shell oval, transverse, solid, inequilateral ; ornamented by salient
and frequently scaly costte ; lunule more or less depressed ; hinge
oblique; right valve carrying one small anterior lateral tooth and
two long posterior cardinal teeth ; left valve with a short anterior
cardinal tooth, one long posterior cardinal tooth, and one small

As given by Bruguiere, Cardita is a mixture of several genera ;
following the rule applicable in such cases we must accept the
interpretation of Lamarck,' who was the first to break up Cardita,
and the type of the genus as given by that author is as here stated.

In his diagnosis the author remarks that this shell resembles
that of C. delicatula, Tate, but differs in not being so abruptly
truncate posteriorly, the umbones are placed a little farther backj
from the anterior margin ; it has fewer, broader, and much more
coarsely ornamented costae. It has also fewer and broader ribs thani
has C. tasmanica, Tate, whilst the interspaces are narrower, andj
the form of the two shells diff'ers.

CrassateUa, audorum {no7i Lamarck, Mem. Soo. Hist. JS^at. Paris,

American authors ' for some time past have recognized that the
name CrassateUites, Kriiger, must be applied to moUusca commonly
known as CrassateUa. In Lamarck's work above cited the type
of his CrassateUa is given as Madra cygnea, Chemnitz (^ M. cygmis,
Gmelin), which may, without hesitation, be referred to the Mactrida3,
and CrassateUa must therefore be employed for certain members of
that family, or fall in synonymy. Kriiger's type, mentioned below,
comes from the Bordeaux area.

Shell piriform, right valve smaller and less convex than the left ;
rounded and globose in front, rostrated and slightly gaping behind ;
hinge-teeth not constant, a small cardinal tooth sometimes occurs
in front of the spoon-shaped depression of the cartilage which is
