NOTE. 

In the year 1888 at tlie request of Sir F. ilcCoy, 
then Director of the National Museum, Mr. George 
Sweet, F.G.S., undertook a cai'eful investigation into the 
rocks of the Manstield district in Yictoria. The great 
majority of the specimens now described were secured Ijv 
Mr. Sweet, who generously placed his time and experience 
at tlie disposal of the Museum — in fact, except for a 
certain amount of assistance in actual manual labour, 
Avhich Mr. Sweet supervised, the collection was almost 
entirely made at the expense of this gentleman, to wliom 
the Museum is much indeljted. On the death of Sir F. 
McCoy it was found that, though the plates which illus- 
trate this memoir had been drawn and printed off under 
his supervision, there was no letterpress referring to them 
other than the very brief notice which was published in 
the Annual Report of the Secretary for Mines in Victoria 
for the year 1889. Under these circumstances they were 
placed in the hands of Dr. A. Smith Woodward, who 
cordially consented to make use of the plates already 
printed off, though it must be understood that Dr. Suiitli 
Woodward is not responsible for these, and that it would 
undoubtedly have been advantageous to him if they could 
have been executed under his own supervision. This, 
however, was not practicable, and the Trustees are in- 
debted to Dr. Smith Woodward for undertaking the 
work under circumstances which could not have been 
altogether satisfactorv to himself.

ON A CARBONIFEROUS FISH-FAUNA 
FROIYI THE IVIANSFIELD DISTRICT, VICTORIA.

I.— INTRODrCTION. 



The fossil fish-vemaiiis collected by ^Er. George Sweet, F.G.S., 
from the rod rocks of the Mansfield IHstrict, are in a very 
imperfect state of preservation. They vary considerably in 
ap})earance according to the nature of the stratum whence they 
were obtained. The specimens in the harder calcareous layers 
retain their original bonv or calcified tissue, which adheres to tlie 
rock and cannot readily be exposed without fracture. The 
remains buried in tlu> more ferruginous and sandy layers have 
left only hollow moulds of their outward shape, or are much 
decayed and thus very difficult to recognise. Moreover, the 
larger fishes are represented only by scattered fragments, while 
the smaller fishes, cvim when a))proximately whole, are more or 
less distorted and disintegrated. 

Under these circumstances, with lew materials for com])arison, 
it is not surprising that the late Sir Frederick McCoy should 
have failed to ])ublish a satisfactory account of the Mansfield 
collection. "With great skill, h(^ selected nearly all the more 
important specimens to be drawn in the series of plates accom- 
panying the present memoir, lie also instructed and supervised 
the artist, so that most of the principal features of the fossils 
werii duly emi)liasiscd. TTis pn'liminary determinations, however, 
published in IS'JO,' are now shown to \ui\n been for the most 
part erroneous; while iiis main conclusions as to the affinities of

the fisli-faima are proved to l)e without real foundation. Far 
from displayini^ a " Mixture of Lower Devonian, Upper Devon- 
ian, and types related to some of the Calciferous Sandstone 
series," as McCoy supposed, the Mansfield fishes are typically 
and essentially Carhoniferous, as the following technical descrip- 
tions will demonstrate. Of the six genera represented in the 
collection, one {Enpleurogmus) is too imperfectly known for 
discussion; four of the others {Acanthodes, Ctenodus, Strepsodus, 
and Elonichthys) have hitherto been discovered only in tiie 
Permian and Carboniferous of Europe, and in the Carboniferous 
of North America; while the sixth {Gi/raca nth ides) is related to 
an essentially carboniferous fish in the northern hemisphere and 
bears every mark of belonging to the same late Palaeozoic period. 

The genus Gyracanthides is, indeed, a remarkable discovery. 
As correctly recognised by McCoy, it is closely allied to Gyracati- 
thus, which is widely distributed as a characteristic fossil in the 
Carboniferous of the northern hemisphere and seems to be also 
represented by a few small spines in the Lower Devonian. The 
new specimens pi'ove that Gyracanthides is a typical Acantho- 
dian, belonging either to the Dij^lacanthidfe or to a distinct 
family which marks the culmination of the Diplacanth series. 
The enlargement of the jiectoral fins, the reduction and forward 
displacement of the pelvic fins, and the absence or peculiar modi- 
fication of the intermediate spines, are features indicating its 
high degree of specialisation. It occupies the same position 
among Diplacanths as that occupied by the Permian species of 
Acanthodes among the Acanthodians with one dorsal fin.' It 
shows that the direction of specialisation was identical in the two 
great groups of Acanthodians, and was analogous to the speciali- 
sation observable in later geological periods among Selachians and 
Teleosteans. 

The total assemblage of fishes in the red rocks of ^lansfield is 
such as occui's usually in estuarine or freshwater strata in the 
northern hemisphere ; but all the genera are likewise met with

occasionally in marine sediments. Their association with numer- 
ous remains of land-plants at Manstield, howevei', is sugc^estive 
at least of estuarine conditi(jns. They do not appear to exhibit 
any essential change as they are traced throut;:h the successive 
beds in the section so carefully worked and described by Mr. 
Sweet.'

Family GYllACANTlIID^. 

An iini)erfectly definable family of round-bodied and depressed 
Acanthodians, with the pectoral fins very large and the pelvic 
fins advanced far forwards. Dorsal and anal fins much reduced 
and sometimes apparently without spines. 

This family has hitherto been known only by detached 2>aired 
fin-spines, other paired spines or plates, and small dermal 
tubercles, the majority belonging to one genus, (Ji/racdiilhits of 
Agassi/,. The s])ecimens of the new genus Gyrcicaiilliidcs now 
described, show for the first time the depressed, rounded form of 
tli(- trunk and the relative position of the fins.

lower faces and iiiclincHl townrds th(^ insci-tcd extnnnity ; tlieir 
narrow posterior face impressed l)y ;i median longitudinal groove 
l)ut without denticles. Pelvic fin-spines ornamented like the 
pectorals, hut i-cmnded in transverse section at the hase and 
nearly straight. Posterior dorsal and anal fins relatively .small, 
with a hroad, laterally-compressed anterior spine, which is 
ornamented with longitudinal tuherculated ridges ; caudal fin 
slightly forked. Two pairs of hollow, hroad, ti'iangular, free 
spines, of fibrous texture, fixed near the insertion of the pectoral 
fin-spines. 

This fish agrees with QyracanthuH in the oi-namentation of its 
pectoral fin-spines and the natvu-e of its free spines; hut there is 
as yet no evidence that the last-mentioned genus possessed pelvic 
fin-spines or any median fin-spiue. It may also he added that 
the pectoral fin-spines of Gyracanl hides hitherto discovered do 
not exhibit any worn surfaces, while the corresponding spines of 
Gyracanthns are often much al;)raded and destroyed at the tip.

ahoiit 13 to 15 on eacli face. 

General Form. — The specimens of the head and al)doniiiial 
region of this species are always exposed either from above or 
below, and ])rove that the i^reater part of the body was originally 
rounded or depressed in transverse section. The only known 
example of the hinder part of the eaudal region (PI. V, fig. 1) is 
displayed in side-view, and indicates that this part was more 
laterally compressed. I'hr type-specimen seems to show the 
complete extent and shape of the head and branchial region, 
while this and another imperfect fossil (PI. I, iig. 7), with the 
caudal region just nuMitioiied, appear to justify the sp(!eitic 
diagnosis, whicli is illiislrated liy the accompanying restored 
sketch (text-tig. 1). 

JIfml. — So far as ])reserved in the typ<'-specimen, the head 
exhibits nothing but the usual close aianour of dermal tubercles, 
without any traces of teeth or circumorbital plates. It also lacks 
indications of branchial arches. The cartilage of the endoskeleton 
cannot have been sufficiently w^ell calcified for preservation. 

Pectoral Fin-spine. — The pain'd fins an; n^presented in the 
fossils solely by their anterior spines, which are always imperfect 
and often preserved only in the form of natural moulds or 
impressions. Owing to its vertieally-eompressed shape the 
pectoral tin-spine is invariably exposed either from above or 
below, and it is shown on both sides of the type-s))eeimen, of 
whicii the left portion is seen in PI. I, fig. 1 (c). Parts of this 
spine are also seen on both sides of the fo.ssil in PI. T, fig. 7 (b), 
I'l. IK Iig. 2 (//), and I'l. IJ f, Iig. 1. More satisfactory ex- 
amples for description are drawn in PI. 11, tig. 1 (c) and PI. IV. 
As indicated by the two specimens last mentioned, the base of 
insertion is much exte'nded, its extent being probably greater 
than one-third of the totjil hmgth of the spine; but this base is 
not very deep, and it a|)pears to have been only (|uite slightly 
produced forwards in front of the ex.sertcd and ornamented

portion. The width of the exserted portion gradually increases 
to its luMxiiuuiii opjxisitc the hinder part of the inserted l)ase, and 
then the s])iii(^ i^radiially tapers as it curves into the loni^ and 
slender extremity, which is (observable through a thin film of 
intractable matrix in the fossil represented in PI. Ill, fig. 1. 
There is no evidence of the shortening of the spine by we<ir 
during life, such as occurs commonly in Gyracanthus. The 
vertical compression of the spine is well seen in a fragment of the 
type-specimen, which indicates that just at the hinder end of the 
inserted base the maximum vertical diameter equals nearly one- 
third of the width, while the dorsal and ventral faces are about 
equally flattened. These two faces are also similar in their 
ornamentation, which consists of oblique ridges, all surmounted 
vritb a regular row of smooth, rounded tubercles (PI. IV, fig. \d), 
and separated by shallow, smooth grooves, whicli are wider than 
the ridges themselves. All the ridges are complete from edge to 
edge of the spine, and thirteen to fifteen of them are cut by a 
transverse section at the hinder end of the base. Their direction 
tends to become more and more longitudinal as they are traced 
from the base towards the apex of the spine, and they may have 
been absent on the terminal portion. The anterior margin of the 
spine (PI. IV, fig. \b) is compressed to a sharp edge, along which 
the several ridges of the dorsal and ventral faces meet exactly in 
pairs. The jaosterior margin (PI. IV, fig. \c) is a narrow smooth 
area impressed by a deep longitudinal groove, which is repre- 
sented by a ridge of sandstone in the fossil-aists (PL II, figs. 2a, 
2e). It is evident that this groove was not quite median or 
bilaterally symmetrical. Its borders are not provided with any 
denticles. The calcified tissue of the spine is rather coarse, 
longitudinal vascular canals being visible to the naked eye, and 
imparting to longitudinal sections (PI. Ill, fig. 16) a fibrous 
appearance. The internal cavity is large, and a remnant of it 
seems to extend to the apex of the sj)ine. 

Anterior Free Pectoral Spine. — -There is no clear evidence of 
fin-supports or a pectoral arch at the base of the pectoral fin- 
spines ; but there are two pairs of wide, hollow, triangular spines, 
which may have projected freely from the ventral asjject of the 

[•5]

body ill a manner not unusual amonof Acanthodians. Remains 
of the anterior pair of tliese peculiar spines are observable on 
both sides of the type-speciinen just in front of the l)ase of the 
pectoral tin-s])ine (one shown at « in PI. I, fi<r. ]). An internal 
cast of the correspondiug spine in a second specimen is shown in 
I'l. I, figs. 7 («), To. An imprint of one face evidently of the 
same spine, scnnewhat displaced, is also seen in I'l. ill, tii.^. 1 
(c); and variously imperfect detached spoeimens are represented 
in PI. I, ligs. 2-6. 'ilie structure is elearly a thin-walled, hollow, 
luterally-coinpressed cone, the lengtli of its base-line e([ualling 
twice its height. Part of its calcified tissue is actually preserved 
ill the type-specimen and in the original of 1*1. T, iig. 4, 
exhibiting a very ))orous texture (see especially I'l. 1, tigs, to, 
\fj) ; and impressions are marked by th(; apjiearance of fibres 
radiating from the apex, crossed by certain lines of growth which 
are concentric witli the basal edge. There are traces of a coarse 
tuliercular ornament at the ajiex of the best-preserved spine in 
the type-specimen ; and this ornament is shown to be confined 
to one face of the spine in the detached exainjile of which 
one lateral impression is represented in PI. I, fig. 2. The 
ornament consists of large, smooth tubercles arranged in ten 
to fourteen rows, which radiate from the ajiex and terminate 
at a short distance from the base of the spine, leaving a 
smooth area which was evidently the part originally inserted in 
the soft tissues, 'i'lic tiibercules increase in size towards the base 
of the spine, where they sometimes subdivide. As shown by 
various impressions (PI. T, figs. 2, 3, 5), this ornamented face bears 
much resemblance to a dental plate of the Dipnoan fish, D/p/enis; 
but even when the rest of the sjiine is not seen, the fossil is 
distinguished from a Dijinoan dental plate by its sharply-defined 
smooth area beyond the termination of the radiating ridges. The 
base-line of this spine seems to have been more or less coincident 
with the long axis of the trunk, while its apex, as crushed in the 
best-preserved fossils, is turned outwards. 

Poatenor Free Pectoral Spine. — The spine just described is 
not very large, the length of its base-line e(|iialling only one-and- 
a-half times the inaximuni width of the pectoral fin-spine. The 

L' J

fivM! spiiuis of the second pair arc mucli lai'i^or and more elevated, 
tlie basal (!xt(!nt of cacli being about one-and-a-lialt times as 
great as that of th(i anterior spine, while the height somewliat 
exceeds this tneasiircincnt. Parts of bolb of these lari;e spines 
are seen in the tyixvspecimen, that of one side l)eing represented 
solely by its ap('X, while that of the otlu>r sidi; is better displayed 
in several broken surfaces. Another good example is well shown 
in PI. II, fig. 1, and lacks only the apex. A more imperfect 
specimen is seen near tin; front of the fossil represented in PI. V, 
fig. 1. This spine is situated opposite and just on the inner side 
of the inserted part of the pectoral flu-spine. Like the smaller 
spine in front, it is a thin-walled, liollow, laterally-compressed 
cone, with its base-line \non'. or less coincident with the long axis 
of the trunk, that is, parallel with the liasal edge of the fin-sjjine. 
Its outer side (Pi. LL, fig. la) is gently convex, with a sharply- 
bevelled area in front (restMubling that of the corresponding spine in 
Gyj'acanthns and Oracanthus^) ; its inner side is flattened or even 
slightly concave, and seems to be emarginate or excavated at its 
basal edge ; its posterior aspect (PI. II, flg. \h) indicates the 
amount of the lateral compression. Remains of the actual 
tissue of th(! spine in the type-specimen show that it was very 
porous, with an appearance of flbres radiating fi-om the apex 
towards the irregularly-crimped base (shown in internal cast in 
PL II, flg. \a). An iuipression of the outer face in PL II, fig. 
1 («) reveals a close ornament of small, rounded tubercles, not 
clearly arranged along the radiating structural lines, which are 
here very conspicuous. These tubercles (PL II, flg. le) are not 
noticeable in any other specimen, probably on account of the 
state of preservation. They might even be marks of the shagreen 
granules of a piece of skin pressed against the spine in the fossil, 
like the tubercular impressions covering the hase of the adjoining 
pectoral fln-spine ; but they are more probably true ornament, 
for similar tubercles occur on the corresponding spines both of

Britain."— Trans. Roy. Dublin Soo. [2], vol. i. (1883), p. 529, pi. Ixiii., fig. 1.

MANSFIELD DISTRIOT, VICTORIA. 



Gi/racaiithiis^ and Or acanthus-. Tlie narrow-ovoid basal opening 
of the large internal cavity of this spine is closed in 1 wo specimens 
by a separate basal plate, which seems to be in its natural 
])osition. This plate is well shown in the drawing of one side of 
the type-sjx'cimcn (PI. I, fig. Ih), and again in PI. II, fig. Ic. 
It is quite as thin as the conical wall of the spine itself, and is 
clearly a separate clement, calcifi(>(l from its centre, from which 
structural lines radiate outwards. It exhibits ti'aces of a tuber- 
cular ornament or of overlying shagn^en-granules in both 
specimens. Its true nature is thus very diflicult to understand, 
and it may even have been somewhat displaced in the fossils. 

Pelvic Fin-spine. — The spines of the ])elvic fins are very 
little more than half as large as those of the pectoral pair, while 
they are much more roinuUul in transverse section and straighter 
than the latter. The pelvic fins themselves are advanced so far 
forwards that the points of tlicir spines scarcely extend backwards 
beyond those of the pectoral spines. Only one displaced pelvic 
spine is partly seen in an accidental fracture of the ^yp6- 
specimen, but the relative position of the pair is indicated 
in PI. I, fig. 7 {c, &), PI. II, fig. 2 {a), PI. Ill, fig. 1 {b), 
and PI. \, fig. 1. In the first two figured examples just 
mentioned, each spine is represented solely by a natural mould of 
its internal cavity with scarcely any impression of the ornamented 
exterior face. In the original of PI. Ill, fig. 1, however, where 
the spines are somewhat crushed together, fragments of their 
actual ti.ssue are preserved, and impressions of their basal ends 
show the characteristic ornament forming jiarallel V-shaped 
ridges on tiie rounded lower face. In tlu; original of PI. V, fig. 
1, there is also the ba.sal end of the spine itself {a). These 
specimens, and the impression of one side of a detached example 
(text-fig. 2), show that tlu^ pelvic fin-spine was ornamented like 
the pectoral fin-spine, with contiiuious, tubereulated ridges, which 
are separated by comparatively wide, smooth grooves. The 
ridges tend to a more and more longitudinal direction as they ai'e

traced from the base towards the slender apex of the spine, where 
there is an indication of a worn snrface. The base of insertion is 
very extensive, as usual, its length probably equalling one-half 
the total length of the spine. One fine example apparently of 
this spine, obtained by Mr. Sweet from Bed W in the Mansfield 
section, is nearly twice as large as the original of text-fig. 2. Its 
outer ornamented face is broken away on the exposed side, but 
the tissue of the spine is sufficiently well preserved for micro- 
scopical examination. It exhibits a remarkably coarse vascular 
structure, identical with that described by Agassiz in Gijra- 
canthns} 

Iledian Fins. — The specimen represented in PI. V, fiij. 1, is 
vei'y im2)erfect anteriorly, showing only a hollow mould of parts 
of the pectoral fin-spines, one displaced large free pectoral spine, 
and part of one of the pelvic fin-spines ; but it is important as 
displaying the caudal region of the fish, with traces of the median 
fins. This fossil seems to have been selected by McCoy {loc. cit., 
p. 24) as the type of a species which he intended to describe 
under the name of Chiraropcdus langtrei ; but the paired spines 
already mentioned prove that it really belongs to the Gyracan- 
thides now under consideration. As shown bv the fisjure. there 
is part of a fin-sjiine above the dorsal border of the trunk (at c) 
opposite the insertion of the pelvic fin-spine. In another more 
fragmentary specimen (PI. V, fig. 2) there is also a small spine, 
chiefly shown by the mould of its internal cavity (i) nearly 
opposite a piece of spine (a) which seems to represent the pelvic 
fin-spine. The first exarai^le might j)Ossibly be the tip of one of 



1 L. Agassiz, "Ee<;h, Poiss. Foss.," vol. iii. (1843), p. 214, pi. A, fig. 6. 

[10] 



MANSFIELD DISTRICT. VICTOEIA. 



the pectoral fin-spines, but the second specimen cannot be 
explained in this manner. It is thus probable that there was a 
small anterior dorsal fin, with a spine, situated opposite to the 
insertion of the pair of pelvic fins. A posterior dorsal fin, opposed 
to the space between the jjclvic and anal fins, is more satisfac- 
torily preserved (I'l. V, fig. 1). Its slender anterior spine is 
nearly straight, and shown in a broken longitudinal section, which 
exposes the large internal cavity and appears to suggest that it 
bore an external coarse tuberevdar ornament of some kind. The 
fin itself is covered with dermal tubercles like those of the trunk. 
The length of its base-line seems to have slightly exceeded the 
height of its anterior spine, which can scarcely have equalled less 
than two-thirds the depth of the trunk at its insertion. The 
anal fin-spine, inserted opposite the hinder end of th(^ posterior 
dorsal fin, is not much more than half as long as the dorsal fin- 
.spine just described ; l)ut it is similar in character, with a very 
large central cavity. Its outer face is not seen in I'l. V, fig. 1, 
but an impression of it on the counterpart of the specimen repre- 
sented in PI. I, fig. 7 (see fig. Id) exhibits an external ornament 
of a few large, tuberculated ridges, which are disposed longitudi- 
nally parallel with the hinder border and successively terminating 
at the front edge. One of the two specimens showing the anal 
fin-spine must be distorted, for in PI. I., fig. 7, this spine {e) is 
observed quite near the ai)ex of tlie pelvic fin-spines, while in PI. 
V, fig. 1, it is further back (probably its natural position). The 
very stout caudal fin (PI. V, fig. 1) is of the usual Acanthodian 
type, with no clear line of demarcation in the fossil between the 
upper caudal lobe and the dermal expansion beneath it. 

Dermal Tubercles. — Both head and trunk are enveloped 
in a close and uniform covering of calcified dermal tubercles, 
which are not enlarged or modified even along the course of the 
lateral line. They are rhombic, usually almost equilateral in 
shape, and closely pressed together. Their inn(;r face, seen on 
parts of the type-specimen, is flattened or even slightly concave, 
and it is pierced in the middle of the oi)ening of a small, persis- 
tent pulp-cavity (PI. I, fig. ]«). Tiieir outer face is raised in 
the middle into a rounded boss, which sometimes exhibits a 

[11]

feeble radiating crimping round the base. This is best shown in 
the original of PI. II, fig, 2 (enlarged in fig. 2c), but is also 
observable in impression in other specimens from which the 
diagrams, PI. I, fig. 76 and PI. II, fig. If, have been made. 
Less accurate drawings are given in PI. V, figs, lb, 2«. The 
imperfect fossil represented in PI. \1. also seems to be an 
impression of a fragment of this dermal armour, but the drawing 
exaggerates the crimping of the tubercles and gives a false 
aj^pearance of lines bounding polygonal tesserije. This specimen 
may possibly have been interpreted Ijy McCoy as part of the 
shield of bis supposed Cephalaspidian, Hhi/tidaspis mnri'ayi. 

Obso-vations. — This species is named in honour of Mr. 
Reginald Murray, who discovered the first evidence of it at 
Mansfield many years ago. Most of the remains of Gyracan- 
thides in the collection evidently belong to it, though some 
fragments may perhaps represent other species which cannot yet 
be distinguished.

A typical slender si)ecies of this genus is represented in the 
Mansfield collection by an imj^erfect trunk and other fragments. 
It evidently belongs to the group which is characteristic of the 
Carboniferous and Permian formations in the northern 
hemisphere.

small, etjuiiateral, flat and smooth. 

Description of Specimens. — The type-specnnen, of which the 
1,'i-eater part is shown in PI. VII, iiij. 1, is associated with the 
imperfect trunk of a similar lish on a small block of sandstone 
which has unfortunately been weathered. The extreme slendcr- 
ness of the trunk and the elongation of the upper caudal 
lobe are indicated ; but the oiilv remains of fins are fragments 
of the dorsal, anal and caudal. The dorsal tin-spine, 
just in front of a cnick in the fossil, is clearly nuich smaller, 
more curved, and more remote than the anal fin-spine, 
which is incomplete distally. IJotli these spines are broken, and 
the anal spine (enlarged in fig. 1/;) dis])lays its extensive internal 
cavity, 'i'he caudal fin (enlarged in fig. \a) seems to be nearly 
complete in the u])per lobe, but lacks the greater part of the 
lower lobe. A larger specimen of the tail (PI. V, fig. 3) is 
similarly imperfect. The very small scales are nearly or quite 
square, and most of them are exposed from the inner face, whicli 
exhibits its usual convexity (PI. VII, figs. Ic, \d). In one part 
of the fossil theii' outer face is distinctly shown to be flat and 
smooth (PI. VII, tig. \e). On the membranous expansion of 
the caudal fin they become minute (PI. V, fig. 3rt). In the 
original of PI. V, fig. 8, the lateral line can be traced to the 
basal portion of the upper caudal lobe, and is only marked by a 
ridge-like displacement, not by an enlargement of the scales.

Desc7'iptio)i of Specimen. — As shown by the figure, which is 
of the natural size, this must have been a rather large 
Acanthodian ; but it is only known by scattered remains of the 
scales and a fractured fin-spine of one individual. Many of the 
scales of the flank are in undisturbed order and exhibit their 
regular arrangement. They are square and apparently solid, 
with a smooth outer face. Immediately above and below the 
course of the lateral line, two of them are fused into an elongated 
scale ; the upper fusion being of scales in contiguous transverse 
series, while the lower fusion affects two scales of one and the 
same series, the result being that tbe enlarged scales are disposed 
chevron-wise, pointing forwards. At the lower left-hand corner 
of the figure the tip of a fin-spine is represented. The adjoining 
part of the fossil exhibits the remainder of this sjiine, which is 
only seen in longitudinal section. It is as stout and straight as 
some of the fin-spines of the Lower Devonian Euthacanthus, and 
has a large internal cavity.

Type. — Hinder ])art ol" cranial roof ('rcxt-lii;'. 3). 

Specific C/iuracters. — Median occipital plate; more than two- 
thirds as broad as long, and its extreme lenu;th about ecpialling 
that of the pair of plates innnediately in Front. 

Cranial Roof. — The roofing bones ol" the hinder hall' of the 
skull are partly preserved in the typ(;-specinien (Text-tig. 3), 
l)artly shown as an impression of their outer face on the matrix. 
The impression proves that they were not externally ornamented, 
their only markings being the usual fine radiating liiu;s of growth, 
which cause the sutures between the various elements to be 
plainly visible. The median occi])ital ])late (O) is shaped as in 
the typical Cfeiiodns ci'isfa/ii.s \'vn]\\ tlic jjuglish Coal Measures,' 
but differs in being rather broader in proportion to its length. 
The posterior median pair of j)lates (1) also agree with those; of 
the type-species except that they are relatively broader ; ajid 
there seems to have Ixvii the usual small median plate (O') 
between their divergent anterior ends. There is nothing worthy of 
remark concerning the lateral paired plates (II, III) so far as they 
are preserved, except that they likewise proove the skull to have 
been shorter and broader than in the type-species just mentioned.

CARBONIFEROUS FISH-FAUNA, 



Vertehrcd Axis. — One frat^mont of the abdominal rei^ion of a 
Dipiinan large enough to have bclongcfl to the head just described, 
exhibits a few very stout, curved ribs like those of the typical 
Ctenodus and Sacfenodufi. These ribs are round in section, with 
the central cavity which is always observable in the fossilised 
state. Two portions of a corresponding type of caudal region 
occur, one being an obscure fragment represented in PI. VIII, 
fig. 12, the other a tolerably well-preserved extremity of the tail. 
These specimens demonstrate the absence of vertel)ral centra, and 
exhibit stout, mesially-constricted, neural and haemal arches and 
fin-supports, which are only superficially calcified. The tail is 
clearly diphycercal. 

Sqiinmation. — -The portion of abdominal region already men- 
tioned exhibits impressions of large, thin scales, resembling those 
of Cfenodus found in the English Coal Measures.^ The charac- 
teristic shape, thinness, and flexibility of these scales are still 
better seen in another piece of limestone, which contiiins some 
fragments of them. They display the usual very fine, radiating 
structural lines, which are crossed by the coarser and more 
irregular concentric lines of gi'owth, without any enamel or 
ornamentation.

[Quart. Journ. Geol. Soc, vol. xxii, 1866, p. 602.] 

Numerous remains of a large Rhizodont fish are contained in 
the coU'ction, and among them it is easy to recognise the scales 
and teeth of a new species of Strepsodus. This genus has 
hitherto been found only in the Carboniferous of the northern 
hemisjihere.

Strepsodus decipiens, sp. nov. Plate VTI., fii^s. 2, 3 ; Plate 

VIII, tigs. 1-11. 

Ti/pe.— Scales (PI. VIII, fig. 10). 

Specific characters. — Scales with the radiating ridges and 
furrows on the exposed portion more numerous than in the 
European Carboniferous species ; the small pits and tubercles on 
the attached face also apparently more numerous than in the 
latter. Teeth [from same horizon as scales and presumably of 
same species] rather large, stout, and nearly or quite smooth, 
with the apex a little incurved but not sigmoidally bent. 

Scales. — The scales exhibit tlie usual variations in form, 
according to their original i)osition on the trunk of the fish, and 
are all more or less round or oval, with a slight truncation at the 
anterior border. Most of them are preserved in a partially 
decayed condition, and they then exhibit their internal structure, 
as represented in PI. VIII, figs. 5, 6, 6a, 7, 10, 11. The 
exposed sector, seen in the lower half of these figures, is not very 
wide. Its tissue is coarser than that of the rest of the scale, 
consisting of stout radiating rods, which are closely ajjposed and 
crossed by a few feeble strands concentric with the border. The 
other part of the scale consists of very numerous radiating and 
concentric strands of tissue of about equal fineness. The differ- 
ence between the two structures is well shown in the magnified 
drawing, fig. 6«, where a portion of the covered area is seen to 
the left, a larger portion of the exposed sector to the right. The 
outer face of the scale is rarely observable, even as an impression 
on the rock; but an imperfect scale associated with the original 
of fig. 10 (the type specimen) seems to show that each radiating 
rod of the exposed sector was surmounted by a delicate supei'- 
ficial ridge, the total number of ornamental radiating ridges being 
thus eonsiderably more than in any scale of Slrepsodiis hitherto 
described. AVlien a complete view of an imj)ression of the inner 
face is obtained (as in the group represented in fig. 9), there is 
clear evidence of the large, antero-posteriorly elongated tubercle 
so characteristic of the middle of the scale in this and some allied 
genera. Occasionally, ivs in the piece of undisturbed squamation 

[17] 



CARBONIFEBOUS FISH-FAUNA, 



impressed on the original of fig. 8, the hinder sector of the inner 
face is shown to have heen covered hy fine pittings and tul)f!rcles, 
whicli are apparently more numerous than in the known scales of 
Slrepsodus. The slime-canal of the lateral line must have been 
large, as shown by its mould (fig. 10). 

Jaws and Teeth. — Tin; collection includes only two portions of 
mandible and a few^ imperfect teeth, which arc; noteworthy as 
being large compared with the scales just described. Tlie height 
of the largest laniary tooth is 0.05 m., while the maximum dia- 
meter of the largest scale is O.OiS m. The remains are sufii- 
ciently well preserved to exhibit the characteristic form and 
structure of a Rhizodont mandible, and the larger of the two 
specimens is represented from the outer aspect in PI. VIII., fig. 1. 
The dentary bone is a thin lamina with traces of an external tuber- 
cular ornament. Its oral margin bears a single regular series 
of small conical teeth, which are very slightly compressed antero- 
posteriorly and are scarcely incurved at the apex. These teeth 
are typically Rhizodont, with folded base and small pulp-cavity. 
Evidence of the shuttle-shaped bones bearing the laniary teeth is 
seen in both specimens ; and one of these elements bearing two 
teeth (namely, one laniary wdth the successor by its side) is 
imperfectly represented near the front end of PI. VIII, fig. 1. 
Like the smaller teeth the laniaries are not sigmoidally bent, but 
only incurved at the apex. They are rather stout, and when 
view'ed in longitudinal section (figs. \a, 2, 3) they exhibit the 
usual pidp-cavity with simjjle foldings of the wall at the base. 
Transverse thin sections of the teeth, wiien magnified, show clearly 
the simple character of the basal folds (fig. 4) and the absence of 
all folding in the upper part where the pulp-cavity still persists 
(fig. 4c). The ordinary thin vertical splenial lamina occiu-s on 
the inner face of the mandible. 

Jugular Plates. — There are several remains of the character- 
istic paired jugular plates of a large Crossopterygiau fish, and the 
two best specimens are shown in PI. VII, figs. 2, 3, They also 
probably belong to Strepsodus decipiens, since it is the only large 
Crossopterygiau identifiable in the collection from Mansfield. 
The original of PI. VII, fig. 2, is an impression of the inner face 

[18] 



MANSFIELD DISTRICT, VICTORIA. 



of a plate, which must have been about three times as hmi;' as 
broad, with sharply rounded ends and a feebly crimped or folded 
edi^e. Tlie orij^inal of tig. 3 is an imperfect ferruginous fossil, 
evidently incomplete at one end and at one lateral margin. A 
third s[)ecimen shows the actual spongy tissue of the bony plate, 
with indications of an irregular tubercular ornanient on the outer 
face. It seems likely that these specimens were misinterpreted 
by McCoy, and were intended for description under the name of 
Pteraspis ^ uKDisfiehleiisis {Joe. cif., p. 24). 

Appeudicnhir Skeleton. — In addition to the Rhizodont frag- 
ments just described, there is a typical small clavicle, bearing an 
external ornament of radiating ruga; and tubercles. There are 
also three stout, hour-glass-shaped internal bones, exactly resem- 
blini; the basal supi)orts of the paired, dorsal, and anal fins in the 
Rhizodonts and their allies.

opercular apparatus equallinf^ nearly one-quarter of the total 
length of the fish and somewliat exceeding tlie maximum depth 
of th(! trunk ; caudal pedicle slender, less than half as deep as 
the abdominal region. Distance between the origin of the paired 
fins equal to that between the origin of the anal and caudal fins ; 
dorsal completely in advance of anal fin. External ornament 
chiefly of strige ; teeth stout. Principal scales of flank not 
deeper than broad, with straight upper and lower edges ; outer 
face of all the scales completely ornamented with fine, somewhat 
oblique ridges, which terminate in the delicate serrations of the 
posterior border ; the ridges on the flank-scales nearly parallel, 
though often bifurcating and intercalated ; those on the lower 
half of the narrow ventral scales curved upwards at the front 
border, and most of them terminating behind at the diagonal 
which joins the antero-sujierior and postero-infevior angles. 

General Form. — The type-specimen is distorted in the ventral 
part of the abdominal region and incomplete dorsally ; but the 
original outline of the fish would probably be almost as repre- 
sented in the diagrammatic sketch, PI. IX, fig. 3. The tail is 
shown to be inequilobate, as usual in EJonicMhys. 

Head. — Although the form and proportions of the head are 
indicated in the type-specimen, its details are obscure and only in 
part traceable. The greater portion of the cranial roof is shown 
as an internal cast, with the mark of the longitudinal slime-canal 
traversing its frontal element ; but a fragment of a plate 
posteriorly bears a finely rugose or striated ornament. The orbit 
was situated far forwards, as proved by an impression of two of 
the circumorbital plates. The outer face of the maxilla is not 
preserved, but its oral border is distinct, curving downwards at 
the hinder end and bearing impressions of very stout conical teeth 
(PI. IX, fig. Ic). Its great postorbital ex2)ansion is about three 
times as long as deep. The slender mandible is very imperfect, 
but fragments of the bone in its hinder part seem to show an 
ornament of longitudinal striations. The characteristic narrow 
opercular apparatus is recognisable, with occasional traces of a 
striated ornament. The forwardly-curved preoperculimi is 

[20] 



MANSFIELD DISTRICT, VICTORIA. 



traversed l)y tlie usual well-developed slime-canal, while the 
suhoperculum is relatively deep. 

AppeudicuJar Skeleton. — ^The supraclaviclo and clavicle are 
seen in the typt'-spcciinen as moderately wide plates, which are 
ornamented with line ridges or striations disposed in tlu; direction 
of the long axis of these bones. There are also remains of the 
pectoral fins, which show that all their rays were articulated, 
though not very closely, for the greater part of their length. 
Both pelvic fins are likewise imperfectly preserved, arising 
slightly nearer to the anal tin than to the pectorals. Each com- 
prises at least 28 rays, of which all are articulated to the base, 
although the length of the spaces between the joints considerably 
exceeds their width. The dorsal and anal fins must have been 
nearly equal in size and shape, the i"ormer completely in advance 
of the latter. They are short and deep, comprising from 25 to 30 
rays, which exhibit distant articulations. Traces of the fringe of 
small and delicate fulcra are seen on the anal fin in the type- 
specimen. The caudal fin is imperfect in this sp(H'imen, and the 
inequality of its lobes is better seen in the original of PI. IX, fig. 
la. The lower lobe is fringed with a close series of delicate 
fulcra, and its rays are veiy finely divided distally. It is 
uncertain whether any of the fin-rays were ornamented, but 
sometimes they appear to bear indications of fine longitudinal 
ridges. 

Scales.— 'Y\\(i principal scales on the fiank of the abdominal 
region are shown by the type-specimen to be about as deep as 
broad. Those on the caudal region are somewhat broader than 
deep, while those near th(^ ventral edge of the fisli are at least 
twice as broad as deep. Those of the flank are united by a large 
and broad peg-and-socket articulation (PI. X, figs. 1, 1«, 16). 
Isolated scales on several specimens show that their overlapped 
anterior border was narrow, as usual in Eloiiic/ifln/s. The out(U" 
face of all the scales is completely covered with ganoine, which 
forms numerous dedicate rounded ridges sejiarated by little sharp 
clefts. These ridges have a general oblique, antero-posterior 
trend, and terminate at the hinder edge of each scale in feeble 
serrations. They often exhii)it a tendency to curve ujjwards in 

[21] 



CAEBONIFEEOUS FISH-FAUNA, 



front ; wliilo not iinoommonly thoy aro inconspicuous on the 
middle of the scale, which then becomes smooth (PI. IX, fig. lb; 
ri. X, figs. Ic, Id, \e. If). The direction of the ornamental 
ridges is least oblique and most regular on the ])rinci])al abdom- 
inal flank-scales (PI. IX, fig. lb; PI. X, figs. 1e, If); nuich 
more oblique or even diagonal on the principal caudal scales (PI. 
X, figs. 1(7, Id, 2a, 2c). The characteristic arrangement on the 
ventral scales is indicated in PL X, fig. 2b. The narrow, 
diamond-shaped, small scales of the u])per caudal lobe are 
ornamented I)y fine, diagonal ridges, as shown by impressions in 
the type-specimen and in the original of PI. IX, fig. la. The 
enlarged ridge-scales are not seen in the type-specimen, but 
some of those in advance of the anai fin are shown in the original 
of PL X, fig. 2. 

Memarks. — 'Jlie impression of an imperfect, relatively large 
trunk re()reseuted in PL X, fig. 2, is not referable to this species 
with certainty ; but the shape and ornamentation of the scales 
seem to agree precisely with those of the fish now described. 
This and the type-specimen were found by Mr. George Sweet, in 
whose lionoiu' the species is named. 

Elonichthts gibbus, sp. nov. Plate IX, fig. 4 ; Plate XL 

Type. — Imperfect fish, lacking end of tail (PL XI, fig. 1). 

Specific characters. — A short, deep-bodied species with com- 
paratively small head, attaining a length of about 0.2 m. Length 
of head with opercular apparatus somewhat less than the maxi- 
mum depth of the trunk, Avhich is contained twice in the length 
from the pectoral arch to the l)ase of the caudal fin. Pelvic fins 
arising about midway between the pectorals and the anal ; dorsal 
and anal tins at least as long as deep, the former not completely 
in advance of the latter. Principal scales of flank in abdominal 
region slightly deeper than hroad ; outer face of all the scales 
completely ornamented with fine, somewhat oblique ridges, which 
terminate in the delicate serrations of the posterior border- 
Enlarged dorsal ridge-scales apparently extending as far forwards 
as the occiput. 

[22] 



MANSFIELD DISTRICT, VICTORIA. 



General Form. — As shown by tlio type-specimen and the 
orii^inal of PI. IX, fig. 4, the deepest part of the trunk of this 
species is at the origin of the dorsal fin, which is remarkal)ly 
large ajid extciidod. The other specimens ai'e more imperfect or 
distorted durini;' fossilisation. 

Ih'iid. — The small head is partly indicated in the typc- 
speeiiiicii, hut hetter shown in another impression (PI. XI, fig. 3). 
The fine ornament on at least th(5 frontal region of the cranial 
roof is partly subdivided into tubercles. The other external 
bones are only striated, the striae on tiie maxilla and mandible 
being mainly horizontal or longitudinal, those on the circum- 
orbital plates (PI. XI, fig. Zb) radiating. The maxilla bears 
large, stout teeth, and its postorbital expansion is about two-and- 
a-half times as long as deep. The opercular apparatus must have 
been very nai-row. 

ApjieiHliciilar Skeleton. — The supi-aclavicle, clavicle and infra- 
clavicle, seen in the type-specimen (PI. XI, fig. 1), are moder- 
ately wide plates, ornamented with fine ridgi;s or striations 
disposed in the direction of the long axis of thes(! bones. The 
length of the pectoral fins can scarcely have exceeded half that 
of the head with opercular apparatus. The pelvic fins seem to 
have been as large as the pectoral pair. The dorsal and anal fins 
are remarkably large and ext<md('d, the former arising at the 
highest point of the back and always depressed backwards in the 
fossils. More than 4,0 rays are indicated in the imperfect dorsal 
fin of the type-specimen, and more than 30 rays are seen in the 
anal fin in the original of PI. IX, fig. 4. The articulations of all 
the fin-rays are distant. 

Scales. — ^The slight deepening of the principal scales of the 
flank in the abdominal region is observable both in the type 
(PI. XI, lig. Irt) and in other specimens. The finely-striate 
ornamentation of the scjiles resembles that already described in 
Ulonic/il/ii/s siceeli, but there is never an indication of median 
smoothness.

INTRODUCTION. 

Sources of the Present Collection. 

A large proportion of the fossil specimens descrilx^d licrcin 
was collected duriiiL;- the first (icological Survey of Victoria, 
under the direction of Mr. (afterwards Sir) A. R. C. Selwyn; 
and was deposited in the National Museum, Melbourne, then 
under the directorship of Professor (afterwards Sir) Frederick 
McCoy, who was at the time also palieontologist to the Survey. 

Verv few of the specimens were identified by McCoy: — a 
single species described in liis IModromus of the Paheontology 
of Victoria* under the name of Canfivm (jijrpslandicuvi 
[ = Panenha fi! pj)slandira], and some fossils generically deter- 
mined for future labelling as Orlhonotus. .Inodonfo/isis. Leptn- 
(lomus. Area, AvindopectPn and Avicula, appear in the Museum 
collections. 

On the I sheet No. 1 N.\V. ]\reliiounie, McCoy noted the fol- 
lowing bivalved genera from Moonee Ponds Creek (" Royal 
Park"), viz., SanguinoHtea ( = Orthnnnfn fnt.ttralis sp. nov.) and 
Cucullella (= Nvndites maccoyianus, sp. nov.). 

The fossil referred to under the MS. name of Oilhonotns 
suhrigidus by McCoy on \ sheet No. 4 S.W. Ceol. Siirv. Vict, is 
MOW shown, by the hinge structure, to be identical with \iiruJa 
InmeUata, d. Hall, and not allied, as McCoy supposed, to 
Orthonota rinida Sow. sp. of tlie Upper T.landovery and Lower 
Ludlow of Great Britain. On the same geological niap a 
Lf'-ptodomvs allied to amyqdoUnns is noted by McCoy. This is 
now shown to be a distinct sj^cies, here named Lt'/>fndonius 
mnrcoyianvs. Certain fossils named in MS. bv McCoy as

The fossil (No. 3368, Mines Dept.) alluded to by McCoy, in 
Progi^ess Tveport No. TV., 1877, p. 156, as " a small Aviculoid 
shell allied to A mhonyckia (new species)", is here described and 
fignired as ])robab]y a young foiin of a new species — Lnnuli- 
cavdiiim ant i striatum. 

Three species of Silurian pelecypoda, which had already 
been described by the Rev. A. W. Cresswell, M.A.,* have been 
presented by him to our collection. These are Conocardmm 
bellulum and C. costatiim, originally described imder the generic 
name Pleiirorhynchvs; and Ptcrinea tatei, previously described 
as an Ambonychia, but probably identical with P. lineata, 
Goklfuss. 

The larger part of the remainder of these Silurian bivalved 
shells has been obtained from the richly fossiliferous mudstones 
at South Yarra over the area of the Yarra Improvement Works. 
They were chiefly collected by Mr. F. P. Spry (now of the 
National Museum). Other gentlemen who have kindly assisted 
us in obtaining new material are Messrs. J. T. Jutson, and A. E. 
Kitson, F.G.S., whilst the oiiportiinc donation from Mr. Thos. 
Warr, of material from a well-boring at Croydon,! has resulted 
in the addition of several new and remarkable forms of aviculoid 
and other shells. In addition to the species previously men- 
tioned, we are also indebted to the Rev. A. W. (^'resswell. M.A., 
for a valuable collection of mudstone fossils from near Lily- 
dale,t which has furnished us with several additional forms to 
our list of species. 

Some Gener.-vl Aspects of the Siluri.an Biv.\lved Fauna. 
The collection now described comprises 62 species and 
varieties, referred to 29 genera. Of the total number, as many 
as 58 species and varieties are here recorded from the Victorian

The following notes on the above-named gcnrra arc cnin- 
piled in order to show^ how interesting is the cjuestion of the 
distribution of the bivalved fauna of the Australian Silurian. 
When our knowledge of this group and of the remainder of the 
molluscan classes is more complete, it will bo possible to make 
some valuable deductions as to the general relationship of thi? 
widely distributed phylum of the animal kingdom, both from 
geological and geographical stand-points. 

Palceanatinn, J. Hall. — Hitherto found onlv in the Upper 
Devonian of North America. 

Cardinla, Broderip. — This is a Silurian genus in Great 
Britain; and it also occurs in the Silurian and Devonian in 
Eastern Europe. It appears to be aksent from North America, 
although the somewdiat closely associated genus, Panenka, is 
found there in Devonian strata. 

Paiien/,a, l^arrande, is lioth a Silurian and Devonian genus, 
but attains its maximum development in the latter formation. 

Paracardimii, Barrande. — This genus occurs in the Silurian 
(Stage E) in Bohemia, and in the Devonian of North Amei-ica. 

Prcnlucina, Barrande. — A well-defined generic group in the 
Silurian and Devonian of Bohemia. Barrande notes the total 
absence of the genus in the Stage Eci, but in the Upper Siluiian 
Ee^ there occur 25 species, whilst in the lowest zone of the 
Devonian, Ff, there are only two species. 

('tenndontn, Salter, is already known elsewhere fiom flic 
Silurian, and its range extends to the Carboniferous. 

Nvndite!^, Conrad. — A Silurian and Devonian genus, well 
represented in the Devonian of South Africa and South 
America. 

Niindn. T.amarck. This genus ranges from Silurian to 
Recent. Probably many of the British Silurian species now 
referred to Ctenodonta may prove eventually to belong to this 
genus. .Mthough originally described as species of \iicvlti. 
some of these fossils appear to have been transferred to ('tena- 
donta, on insufficient evidence of the hinge characters."* 

Parallelodon, Meek and ^^'orthcn. — Tt is interest iu'j' to 
record this genus from the Silurian of Victoria, since it had an 
already-known range from the Devonian to Tertiary.

SILURIAN BIVALVEn MOLLUSCA OF VICTORIA. 

Actinodesma, Sandberger. — Although the liitherto-rccorded 
range of this genus is restricted to the Devonian, there is very 
little doubt that it is represented in the Silurian (Upper Lud- 
low) of Wales by the so-called " Avicula" or " Pterinea" 
amj)liata, to which our fossil bears a close resemblance. 

Lurmlicardium, Miinster. — This genus is confined to the 
Silurian and Devonian. In Bohemia it is found throughout 
both formations; in North America only in the Devonian. 

Mytilarca, J. Hall. — Well-represented in the Devonian of 
North America. It occurs in the Silurian (Wenlock shale) in 
England, usually referred to as Mytilus. The British Silurian 
fossil recorded as Mytilus chemKngensis seems to differ 
from the species originally described by Conrad from the 
North American Devonian. The genus occurs in the upper 
division (Yeringian) of the Victorian Silurian. 

Glossites, J. Hall. — Fossils of Devonian age in North 
America (Corniferous Limestone to Waverly Group); and in 
South Africa (Bokkeveld Beds). 

Cypricardinia, J. Hall. — This interesting genus ranges 
through the Silurian and Devonian, both in Europe and North 
America. It is here confined to the upper beds of the Silurian. 

An inquiry into the number and distribution of the Vic- 
torian species which are also found elsewhere in homotaxial or 
closely-related strata, affords some interesting data. There are 
no less than eleven species of Silurian bivalves (18 per cent.) in 
our Victorian rocks which can be identitied with fossils found in 
other, often widely separated areas. Regarding the occurrences 
of similar fossils in Great Britain, shown by the subjoined table, 
it will be noticed that, with few exceptions, the distribution 
ranges through the AVenlock and Ludlow series, whilst in Ger- 
many and Bohemia the fossils occur in the Lower and ^Middle 
Devonian.* The species of bivalved mollusca which occur in 
North America are found in the IMiddle Devonian, but not 
below it, whilst one of our forms is also found there in L'pper 
Devonian rocks. From this the inference may be drawn, that 
since both in Western Europe and Australia the species made 
their first appearance in the Silurian, the point of dispersal 
would probablv be situated mid-wav between tliose places, pro- 
vided the conditions were equal, and that there were no barriers 
to their migration. The data given below would also appear to 
implv that consideral^le obstacles did exist against their dis- 
persal along the radius extending to Eastern Europe (Germany

and Bohemia); ami in the same proportion complex and adverse 
conditions prohahly obtained on the inioratnrv path to North 
America. 

Further proof of the general trend of these comparative 
data as derived from other gronps of the Victorian Silurian 
Mollusca is shown in the Museum collections; oiie notable 
example being the occurrence of a gasteropod, Eiioni/i/ialns 
(/if'jiinrti/s, J. Hall.* in the Victorian \eringian division of the 
Silurian, specimens of which are inseparable from the shells 
described by Hall, from the Lower Helderberg of New^ York 
(T.. Devonian). The Pteropod. Coleohts acicvlum, J. Hallt of 
the Middle Devonian (Gencssee Slates) of North America, 
has a close relation in a form which may eventually prove to be 
identical, and which is not uncommon in the McllKnirnian shales 
of South Yarra.j:

SILURIAN lilVALVEJJ .MOLLU.SCA OF VICTORIA. 

Tlic large majority of the species of Silurian bivalves herein 
(i(>s( ribofl are in more or less close relationship with those found 
elsewhere; at the same time they appear to be sufTiciently dis- 
tinct to warrant their separation as nevi^ species. AVhen closely 
examined, the data afforded by these " paramorphs " or alliod 
forms, are of the greatest interest ; for these, as well as the more 
cosmopolitan species above enumerated, shed considerable light 
upon the generally obscure rpiestions regarding the relationship 
of our Australian palaeozoic faunas to those of other areas. 

The subjoined table is an attempt at giving a synopsis of 
the species clescribed from other areas, which, ai>parently, are 
most closely related to the Victorian Silurian pelecypoda. A 
glance at this table will suffice to show that, as in the former 
table of identical species, the general aspect is nearly the same 
with regard to the several areas known elsewhere. 

In Great Britain and Ireland some of our species find their 
affinities with Upper Ordovician forms (very rarely), with 
Silurian, Llandoverv to Ludlow (commonly), and in the 
Devonian (very rarely). Tn Germany related species occur in 
the Devonian (very rarely). 

Tn Bohemia their relationships are found in typical 
Silurian and Lower Devonian strata (rarely). 

In Canada, a single allied form occurs in the Silurian. 

In the United States the many related forms range through 
the Devonian, from the Hamilton to the Waverley groups; 
whilst only one species having related characters is found in the 
Upper Ordovician. 

The question as to whether the Lower Helderberg group in 
North America should be correlated with the Devonian, as main- 
tained by Continental geologists, who recognise in it the equiva- 
lent of the Coblenzian; or with the Silurian, as held by American 
geologists, is a difficult point to determine. The fauna of the 
uppermost beds of the Silurian in Victoria seems to support the 
American geologists to some extent ; for it includes many types 
of trilobites, many representatives of the CajniUdce, and 
certain spirifers which, although characteristic of the Hercynian 
fauna of Europe, are also Helderbergian in aspect. There seems, 
therefore, as much evidence in support of the one opinion as the 
other, and it is merely a question of recognising the possibility 
of the subsequent migration to another area of a distinctive 
fauna, with a minimum amount of change in its facies.

No attempt is here made to subdivide the two series 
of the Victorian Silurian, designated by Prof. J. W. Gregory as 
Melbournian and Yeringian.* It was evident, during the pro- 
gress of the present work, nevertheless, that several horizons can 
eventuallv be defined, after further detailed work has been done, 
by conjoining the stratigraphical and palreontological data.

Class PELECYPODA. 

Family Solenopsidae. 

Genus Orthonota, Conrad, Ibll. 

Orthonota aiistralis, sp. nov. PI. I., Fig 1. 

Description. — Shell large, elongate; dorsal and ventral 
margins parallel; posterior margin well rounded. From the 
umbo to the posterior margin slightly more than twice the height 
of the shell. 

Valves rather strongly convex, moderately steep «jn the 
ventral margin, and sloping away towards the posterior cardinal 
area, where they are more compressed. 

Beaks situated close to the anterior extremity, ratliei- 
prominent. 

Surface of the valves ornamented with a series of strong 
concentric sulci, interrupted below the high umbonal lidge by the 
cincture, which is limited on each side by a furrow.

beds, near Kendal. In tliis .species the concentiic |)lications are 
not nearly so pronounced as in tlie Australian form. Another 
species which may he comijared with ours i.s Orthonotu undulata, 
(.'ourad.* This lo.ssil occurs in tlie Jlamilton Group in the 
United States. Although generally resembling our form, it is 
not so convex, and it has the concentiic fuiicms inidulate in tlic 
posterior area of the shell; whilst the portion between the 
umboiuil ridge and the post-cardinal slope is more numerously 
relieved by radiating folds. 

Obserrations. — The Orthonota occurring in the Silurian 
beds at Yass, New South Wales, and recorded by Prof. T. W. E. 
Davidt in his geological section of that district as Orthonota 
rlgida ? [Sow. sp.] appears to be a new species, judging from a 
specimen in the National Museum from the Shearsby collection. 
It is not related in any way to McCoy's Victorian 0. stibrigida 
(MS.), which is further on shown to be referable to Nucula 
lameUata. Compared with Orthonota aiist rails, sp. nov., the 
Yass specimen is more compressed, and has a more pronounced 
mesial sinus.

Family Grammy siidae. 

Genus Grammysia, E. de Verneuil, 1847. 
Grammysia abhreviata, sp. nov. PI. I., Fig 2. 
Description. — Shell subquadrate, cardinal line arched; 
ventral margin nearly straight, slightly incurved at the junction 
with the umbonal depression, the latter meeting the ventral 
margin a little in front of the median third. Surface of shell 
rather strongly convex towards the beaks, which are sub-anterior. 
A sub-umbonal depression in front of the shell makes a slight 
angularity reaching from the nmbones to the antero-ventral 
margin. In the figured specimen this angularity is emphasized 
by crushing. From the umbo to the postero-ventral margin

there is an obtuse shoulder, and from thence the surface slopes 
rapidly away to the posterior margin. The presence of the 
posterior shoulder and the moderately prominent beaks preclude 
this form from being referred to the genus Cardiomurpha, to 
which it ol her wise bears .some resembhmce. The valves are 
concentrically striated or finely suleate, and the character of 
these surface markings is closely comparable with that seen in 
the smaller species of Gramviysia (lcscril>etl from the Hamilton 
Group of iSorth America.

Approximate length, 28 mm. 

Height, I'l mm.

Observations. — The fossil recorded as ? Cypricardia retusa, 
ksowerby,* of the Upper Ludlow series of JUeibury, near l>udlow, 
bears a striking resemblance to our species, w itli the 
ditference, however, that in the latter the beaks arc situated 
farther forward, and the postero-umbonal slope has an accen- 
tuated shoulder. Another somewhat allied form is Grammysia 
ulrichi, Clarke,! from the Devonian of Brazil.

SILURIAN BIVALVED MOLLUSCA OF VICTORIA. 

Affinities.— This type of shell belongs to the gi(iii|) exempli- 
fied by Grammysia subaicuaia, J. Hall,* from the Chemung 
Group of N. America, especially in having a forwardly pro- 
jecting beak with the ventral border narrowing anteriorly. 
Another form also distinctly i'elate(l, is the Myacites striatiihis 
of Ivdmer.t whieh notably differs in its more depressed beak. 

Oliscreatio/if.— h is interesting to iccoid that McC'oy, who 
established this genus, selected the specimen now ligured, as an 
example of Leptodovius; it was, however, not specifically de- 
termined. Tliis is probal)ly the same form to which McCoy 
referred in a note on I sheet. 4 S.W. Geol. Surv. of Victoria, 
as " Leftodomus allied to amy(jdaUnns."\ The species named 
may be allied to Hall's genus t* holadella. 

It is appropriate to dedicate this species to one who did 
such signal work in describing many typical genera and species 
of British palseozoic niollusca. 

Horizon and Locality. — Silurian (Melbouniian). Type 
specimen [970] from Jiroadhurst's Creek, east of Kilmorc, Geol.

Leptodomiis heathcotiensis, sp. nov. PI. I., Fig. 5. 

Description. — Shell subtrigonal, elongate, compressed; 
rounded in front, subtruneated l)ehind : ventral margin more or 
less parallel with the cardinal border, but slightly incurved, 
owing to a feeble sinus extending in a vertical line from the 
beaks to the ventral margin. Beaks anterior, salient, and nearly 
terminal. Cardinal line straight. Posterior cardinal area 
hollowed from the beaks to the j)OStero-ventral margin, resulting 
in a curved umbonal ridge below. Median area depressed. 
Surface having numerous parallel concentric ridges (about 18 
to 20).

Ludlow of Benson Knot, Kcndtal, Westmoreland. The charac- 
ters which separate our species from McCoy's are the depressed 
umbones and the more closely striated surface in the former. 
In common with the Ludlow species, the specimens from Heath- 
cote also show the same variation in the length of the shell; our 
figured type being a rather elongate form. 

Horizon and Locality. — Silurian (Melbournian). Ranges 
east of Heathcote. Coll. of the Geol. Surv. Vict., B''- 50

Observations. — The specimen before us is unfortunately in- 
complete, but there is enough evidence to show that it was thin-

Description. — Shell sub-ovate, oblique; thickest in the 
median and umbonal area. Beaks rather inflated, directed 
forward, and situated anteriorly. Anterior border short, and 
truncated towards the ventral margin, curving widely to the 
posterior extremity, where it turns abruptly upwards to meet 
the cardinal line. Cardinal border moderately short. In the 
cast of the shell there is a depression beneath the posterior 
umbonal slope indicating a ridge or support inside the shell, 
terminating in a semilunar muscle scar. The posterior area of 
the shell is compressed, and almost nasute at the postero-ventral 
margin; and sometimes it is expanded, as in Ptycliodesma, J. 
Hall, to which this forju shows certain affinities. Surface of 
shell with fine concentric lines of growth, and obscure radii, 
especially noticeable on the umbonal slope. 

The shell of this species was evidently very thin, since the 
sculpturing is conspicuous on the casts.

Genus Sphenotus, J. Hall, 1885. 
Sphenotus warburtonensis, sp. nov. PI. I., Fig. 10. 

Description. — [Details from an internal cast.] Elongate- 
ovate: anterior extremity short, posterior broad and compressed. 
Beaks prominent, sub-anterior; a well-marked umbonal 
ridge running from the beaks to the post-ventral border. 
Cardinal line nearly straight; area having several long, undulose 
and thin lateral teeth, posteriorly, and two short cartlinal teeth 
beneath the beak. Ventral margin sinuous, incurved towards 
the middle, where it meets a conspicuous cincture in front of the 
umbonal ridge. Shell compressed tencath the beaks, and with 
the margin rounded to the ventral border. A strong adductor 
impression occurs under the beaks, situated half-way to the 
ventral angle. Surface of cast marked by strong lines of growth 
at wide intervals, shown as deep groovings. 

Measurements. — Length, 53 mm.; height, 25 mm.; depth 
of valve, G nun. 

Ohservntions. — Tiio al)ove species is typical of the genus in 
all essential details. It differs from Modiolopsia, to which genus 
it might othei\vi.sc be readily referred, in having the charac- 
teristic lateral teeth and anterior cincture. 

It is noteworthy of this genus that elsewhere, as in England 
and N. America, it has hitherto only been recognised in the 
Dovonirin; but its occurronce here, in one of the highest beds of 
the Victorian Silurian, is not surprising, since we already know

Cardiola interrnj)ta, Sowerby, 1839, in Murchison's 
Silurian System, p. 617, PI. VIIL, Fig. 5. 

Observations. — Our Australian specimens present no dif- 
ferential characters by which they can be even varietally sepa- 
rated from the well-known European species. Numerous 
examples of ('. cornuco'pice from Bohemia in the National 
Museum collection help to confirm the opinion of Sowerby and 
others regarding the identity of that species with C. interrupta. 

Although Sowerby's specific name {interrupta) is almost 
universally used for this form, it must unfortiinately be set aside 
for the earlier described C. cornucopice of Goldfuss. The 
specific name C. interrupta, given by Sow-erby (not Broderip, 
as Fischer in his "Manuel de Conchyliologie," gives it) was not 
published until two years after that of Goldfuss' description. 
There was no previous reference to, nor description of, fJ. inter- 
rupta, as Murchison would lead one to suppose (see his foot- 
note— Silur. Syst., p. 617); for turning to the Proceedings of 
the Geological Society of London, Vol. II., under date January, 
1834, p. 13, the reference given by Sowerby and Murchison, no 
allusion to ('. interrupta is found, while in the Table facing p. 
13, Div. I., Ludlow Rocks, we read — " Cardiola," Brod., a new 
genus, 2 spp. My friend Mr. C. Davies Sherborn, F.G.S., who 

* In Progress Report No. IV. Geol. Surv., Vict., i8;;, p. 156, there occurs .-i note by 
McCov on this and associated fossils, stating them to be of Ludlow age. Even at the 
present time we cannot speak much more definitely, but judging from the strong Devonian 
aspect of the fossils they may be even comparable in part to the Dowtonian.

('(trdium aippslandicuvi, McCoy, 1879, Prod. Pal., Vict., 
Decade VT., \x'2\i., 1>1. LVI. 

Observations. — In describing tlii.s fossil under the generic 
name of Cardium, McCoy wrote : — " Although not quite satis- 
fied with ihc generic reference to Cardium, still it is congeneric 
with the previously described Upjjcr Silurian Cardiums." At 
that time the genus to which we now refer it had not been estab- 
lished, but in 1881 Earrande separated those forms with ex- 
panded superior margin and strong radial and concentric 
ornament from Cardiola, Broderip, to which the Upi)er Silurian 
"Cardiums" were afterwards referred, and ])lae('(l them under 
the above generic name. In Victoria, the genus PanenLa is 
found associated with Silurian and occasional Devonian forms, 
in one of the highest group of the Yeringian IkmIs; it is 
characteristic of the Silurian and Devonian in J5ohcniia (stages 
1'' to G), and of Devonian beds in Devonshire and N. America.

behind. Height nearly equal to the length. Beak.s prominent, 
sub-central, slightly anterior, and directed forward. Surface 
of shell not much inflated, with the greatest convexity towards 
the middle; ornamented by about 10 flaltcned riblct.s on tlic 
median area, each having towards the ventral border a distinct 
groove, becoming evanescent beyond half the length. I\)stero- 
dorsal area bearing a few riblets, disappearing toward the 
beaks. 

Measurements. — Length of the type specimen, 4.25 mm.; 
height, 4 mm. 

Observations. — This ibrm might be regarded as the imma- 
ture shell of P. gijJfslandica, but for the distinguishing feature 
of the riblets, which are depressed and grooved, whilst in P. 
rfipjx^Iandica they are simply and sharply ridged. 

Affinities. — The nearest related form to the above appears 
to be Barrande's Panenka nana.* from Stage E in Bohemia. 
The chief differences shown in the latter are the more numerous 
riblets, the narrower interspaces, the double strise on their sur- 
faces, and the general form of the shell, Avhich is not so 
depressed; neither are the alae so well developed as in ours.

Panenlca cingulata, sp. nov. V\. I., Fig. li. 

Description. — Shell of medium size, obovate, ventral border 
evenly rounded, abrupt in front, produced behind. Surface 
evenly convex in the median area and near the umbones; concave 
anteriorly, depressed posteriorly. Beaks oblique, pointing for- 
ward. Surface ornament consisting of about 26 curved ribs 
radiating from the umbo, well-rounded, closely set and separated 
by deep furrow^s. The ribs are transversely crossed at intervals 
by the rather deep concentric furrows, which apparently repre- 
sent distinct stages in the growth of the shell, causing 
interference with the continuous and even growth of the riblets. 

Measurements. — Length, 38 mm.; height about 26 mm.; 
greatest depth of valve, 5 mm. 

Observations. — The regular convexitv of the valves, and the 
rounded ribs render this form easily distinguishable from P. 
gippslandica, McCoy.

species, was presented to the National Mnsenni by Mr. R. Jacob

Hill, Christmas Hills, in strata apparently of abont the same 
horizon as that of the type sj)ecinicn. In this example the sliell 
is higher than the figured type, but this difference may Ik; 
due to compression; the concentric furrows also are not so well 
marked. [7880.] 

Genus Paracardium, Barrande, 1881. 

Paracardium filosum, sp. nov. PI. I., Figs. 15, 10. 

Description. — Shell sub-trigonal, the beaks prominent, 
ventral margin rounded and expanded. Surface contour well 
arched, especially in the umbonal region and towards the 
ventral margin. Surface ornament consisting of about 22 fine, 
flattened riblets, grooved medially. Cardinal line not perfectly 
preserved, but apparently less extended than in the previous 
genus. 

Affinities. — The small size of the shell, together with the 
prominent, incurved umbones, and the sub-truncate posterior, 
show this fossil to belong to the genus Paracardium. It closely 
apjiroaches Barrande's P. fiUferum* in surface ornament, but 
dilVers in the more regular proportion of the fine and coarse 
riblets. The Bohemian examples occurred in the Silurian 
(Stage E).

(Ee.). Although we have only a mould from a single specimen 
to judge by, there can be no hesitation in assigning our example 
to the above species, for it shows the following characters in 
common with Barrande's figured specimens : — Shell longer than 
high, sub-oval, truncatcly lounded in front at the base, boldly 
curved behind; beaks low, pointed slightly forward, and situated 
anteriorly. The riblcts are numerous (risuallv about 80), 
rounded; moderately strong on the basal margin, becoming very 
fine and almost obsolete towards the umbo. The shell-surface 
is marked with concentric, inequidistant furrows. 

The hinge characters are not shown in any of Barrande's 
specimens, nor in ours, but in the latter the area on either side 
of the beaks is marked with several conspicuous short, curved 
folds or ligamental grooves, more or less parallel with the car- 
dinal border. 

Compared with actual Silurian (Stage E in the Bohemian 
Basin) species of the genus, our specimen differs from the 
nearest allied form, P. lustralis* in its more sharply truncated 
anterior, and higher shell.

quarter sheets of the Geological Survey of Victoria. Since 
Conrad's genus Nuculites is essentially the same as McCoy's 
Cucullella, and antedates it by some years, it is obviously the 
correct one for adoption.] 

Nuculites maccoyianus, sp. nov., PI. II., Figs. 21-23. 

Description. — Shell elongate-ovate; variable in size, and to

anterior border; posterior extremity rounded, sometimes com- 
pressed, narrow and flange-like. Cardinal area having the 
characteristic taxodont hingo. Surface moderately convex,

valve carried an anterior buttress or clavicular ridge immedi- 
ately in front of the umbones, and there is a distinct posterior 
adductor im|)rossion midway between the beaks and the pos- 
terior margin. The specimens found are practically in the 
form of internal ca.sts and moulds, but the latter show indica- 
tions of a surface ornamentation of concentric rugae or lines of 
growth.

Affinities. — The Nuculites ohlonrjatus of Conrad* from the 
Hamilton Group in North America is, in general features, 
closely coniparahle with our species, hut differs in having a rela- 
tively greater length and a straight ventral margin. With re-

Nuculltes subquadratus, sp. iiov. J 'I. II., Figs. 26, 27, 27«. 

Description. — Shell of medium size, subquadrate in out- 
lino, narrower anteriorly; the ventral border l)roadly curved and 
truncated towards the jiostero-cardinal angle. Beaks rather 
prominent, situated sub-anteriorly and directed forward. 
Anterior buttress impression commencing just in front of the 
i)eal\, curving slightly, and traversing al)out two-thirds of the 
distance to the ventral margin. Posterior adductor impression 
strong. Surface highly convex; median area near the beaks 
dejtressed. curving evenly to the ventral margin, rather steep 
towartl the postero-ventral angle, presenting a decided umbonal 
slope; depressed immediately below and in front of the beaks. 
Shell surface ornamented with closely-set, concentric lines of 
growth, and crossed by fine stria?, which apparently radiate from 
the umbo, becoming stronger towards the ventral margin. 

Measurements. — (1) Length, 11.5 nun.; height, mm. (2) 
Length, 6 mm.; height, 5 mm. 

Observations. — This species is unusually short, and reminds 
one of Area in its squareness. The two specimens figured, 
although differing somewhat in details, are referred to the 
same species, as they agree in their essential features. 
In A', subquadratus we have a surface ornamentation similar to 
that seen in some of the better-preserved British specimens of 
vV. coarelatus, this feature of the radiating stria? apparently 
being confined to these two species. 

Affinities. — The present species very closely approaches A^ 
nyssa, J. Hall.* from the Hamilton Group of N. America, but 
the latter form is not marked with radiating stria?, nor is it so 
quadrate in outline.

Affinities. — The nearest form to the above appears to be 
Nuculites oblongatus, Conrad,* a fossil of the Hamilton Group 
of N. America, and already compared with our A. maccotjianus. 
The above species differs, however, from the N. American 
example in being slightly more convex at the umbones, more 
strongly curved on tlic ventral margin, and more attenuated 
posteriorly. It differs from the previously-described A', mac- 
coyianus in the more forward position of the beaks and the 
acuter posterior extremity.

Affinities. — This species resembles in outline A', bellistriata,

the fine concentric sculptuiiny of the surface seen in the latter. 

Observations. — A', melbuurnensis is variable in outline, and 
although agrcein<.f in general form, a series can be readily 
collected which shows a regular gradation from narrow-oblong 
to broadly-ovate, or even sub-orbicular forms. It is abundant

Nucula umbunata, sp. nov. PI. II., Figs. 34, 35. 

Description. — Shell sub-trigonal, oblique; strongly convex, 
especially toward the beaks. Ventral margin gently rounded; 
anterior border widely curved, sloping steeply and sub-truncated 
at the junction with the ventral margin; the posterior border 
is formed by a long curved slope, meeting the ventral margin 
somewhat abruptly. Beaks not very prominent, incurved, 
gibi)ous. Umbonal slope narrowly rounded, extending from the 
beaks to the postero-ventral margin. Surface of shell marked 
by several strong concentric varices, between -which occur 
numerous line growth lines. One specimen shows the ligament- 
pit (resilifer) very clearly. 

Measurements. — Length, 11 mm.; height, 9 mm.; depth of 
valve, 3.5 mm. 

Affinities. — Both in the general form of the shell and its 
surface ornamentation our species shows some relationship with 
.V. rnrirosa, J. Hall.t a fossil from the Hamilton Group of N. 
America (N. York State). A marked dilleience, however, exists 
between them, in that the Australian species has sub-;inleiior 
beaks which are not prominently directed forward.

Nucula arcceformis, sp. uov. I'l. II., i-"ig. ^6. 

Descrij)tion. — Shell sub-rectangular, oljlong; strongly 
convex toward the beaks, sloping away toward the ventral 
margin, which is depressed and almost flange-like. Beaks 
])romincnt, sub-central, directed slightly forward. IJoth ex- 
tremities vertically truncate and only slightly rounded; ventral 
margin straight. Surface marked by irregular and somewhat 
coarse undulations or lines of growth, especially conspicuous 
near the ventral border. 

Measurements. — Length, 15 mm.; height, 10 mm.; depth of 
valve, about 2.5 nun. 

Affinities. — The shape of the valve in this species is pecu- 
liarly rectangular, and not quite comparable with any form 
hitherto figured, the nearest being Nucida subcecpialis, McCoy, 
sp.,* from the Upper Llandovery beds of the Malverns and 
Wales. The latter species, however, is much more gibbous in 
the umbonal area. A fragment of another valve is fortunatelv 
found underlying the figured specimen of N. arccBformis, which 
shows the form of hingement to belong to the genus Nnciila. 

Horizon and Locality. — Silurian (Melbournian). In the hard 
black shale of the Domain-road Sewer, and the blue mudstone

Nucula taylori, sp. nov. PL II., Figs. 37, 38. 

Description. — Shell small, sub-ovate. Beaks prominent, 
incurved, sub-acuminate, sub-central. Cardinal line strongly 
arched. Ventral margin gently and evenly rounded, curving 
boldly anteriorly, and sharply at the posterior extremity, where 
it is truncated toward the beaks. A well-marked umbonal 
slope runs from the beak to the postero-ventral margin. 
Cardinal area on both sides of beak depressed. Surface smooth, 
or with a few faint lines of growth. 

Measure7iients.—\.Q\\gi\\, 6.5 mm.; height, 5 mm. 

Affinities. — iV. taylori bears some resemblance to Nactda 
anglica, d'Orbigny,t which ranges from the Caradoc series to the 
Lower Ludlows in liritain; the chief difterence being the greater 
convexity of our form, especially in the umbonal region.

Observations.— In the general shape of the valves and their 
surface ornamentation our Victorian variety agrees fairly 
closely with the form figured by J. Hall under the names of 
Cucullcea ojiivia and Nucuki randalli. [[all ivmai-ked on the 
identity of the fossils desci'ihcd under the two above-named 
species,* but preferred to retain the later name since it had 
"gone into the literature of the science." The earlier name, 
however, should undoubtedly be employed, in accordance with 
accepted rules of nomenclature. 'J he N. American examjiles 
were obtained from the Hamilton Group of the State of New 
York. 

The Victorian specimens are much smaller than the N. 
American, the largest measuring only 13 mm., whilst the average 
length of J. Hall's e>cam))les is about 23 mm. In the Vic- 
torian variety there is a greater tendency for the concentric 
striae to liecome fasciculate. Two of our specimens (PI. III., 
Figs. 41, 43) show a remarkable gibbosity of the umbonal area.

Observations. — Our figured specimen is a crushed valve of 
a Nycula, showing the ligaineut-pit and denticulate cardinal 
area. The strong lirae and the general form of the shell, point 
to an affinity with the above species, which occurs in the 
Hamilton Group of N. America.

I., Lamell. II., p. 320, PI. XLV., Fig. LJ; PI. LL, Figs. 18-21; 
PL XCIIL, Fig. 7. 

Observations. — This species of Nucula is of a somewhat 
different type to the usual forms, particularly in the sub- 
quadrate outline, and the sub-central position of the beaks. A 
connecting link between the sub-ovate forms and this species is 
exemplified in N. lirata, Conrad, sp.* 

In nearly all the Victorian specimens before us, represented 
either as internai impressions or hollow casts, the ligament pit 
is visible. One of our fossils (Fig. 45) appears to be a short 
variety of the above species. The specimens referred to by 
McCoy on quarter sheet 4 S.W., Geol. Surv. Vict, (notes on Bb. 
18, 20, and 22), under the MS. name of Orthonotus suhrigidus 
are here included under Nucula lamellata, J. Hall.

SILURIAN BIVALVED MOLLtJSCA OF VICTORIA. 



Family Ledidse. 
Genus Pal/EOneilo, J. llall, 1870. 
Palceoneilo victorice, sp. nov. PI. III., Figs. 47-49. 
Description. — Shell of variable size, length more than twice 
the height, rostrate; moderately convex in the umbonal region 
and the triangulai' aiea beneath, tlic latter bounded Ijy the 
anterior slope ami the posterior umbonal ridge. Cardinal line 
nearly straight w oidy slightly arcuate; ventral border sub- 
parallel and .straight, but nai'rowing the shell i)ustci'iorly, widely 
roimded anteriorly to meet the cardinal line at an obtuse angle; 
the hind extremity narrow, with the postero-ventral angle 
bluntly I'uunded, curving backward and inward to the cardinal 
line, which posteriorly torms a salient angle. Escutcheon well 
marked, the depressed area bounded abruptly by the umbonal 
ridge. Surface of shell gently convex and sloping anteriorly; 
towards the ventral margin the surface slopes more steeply, 
whilst the margin itself, in adult shells, is depressed and flange- 
like. Beaks sub-central oi' slightly posterior, prominent, some- 
what incurved and depressed, or only moderately inflated. 
Hinge showing an alternating series of curved bars and sockets. 
On the cardinal border there is a well-marked groove to receive 
the external ligament. Surface ornamented with numerous 
concentric lamellar ridges, between which are several parallel 
thread-like stria?, whilst, in a very few well-preserved examples, 
traces of fine lineations radiating from the umbo are seen, 
especially stronger on the salient edges of the concentric 
lamellae. 

Measurements. — Type specimen (PL III., Fig. 47). 
Length, 27 nun.; height, 12 mm.; number of concentric lamellte 
in the space of 4 mm., measured in median area — 7. 

A medium-sized example. — Length, 17 mm.; height 7.5 
mm.; number of concentric lamellai in the space of 4 mm. in 
the median area — 9. 

A small example. — Length, ID mm.; height, 6 mm.; 
number of concentric lamellae in space of 4 mm. — 16. 

Observations. — The number of the concentric lamellar 
ridges to a given width is not a factor of any importance in 
dealing with this group, so far as the Victorian examples show, 
and the various graduations in ornament do not allow of even a 
sub-varietal division of the species. A possible explanation of 
this varying feature in ornamentation, and one partly borne out 
by the evidence liefore us is, that in areas of quiet sedimentation 

[ 33 ]

SILURIAN BIVALVED MOLLUSCA OF VICTORIA. 



the molluscs found time and material for forming a broad 
varix along the pallial border; whereas in sandy areas or under 
impure conditions of the water, as, for instance, in the presence 
of decaying Crustacea and cephaloi^oda, seen in the JJomain- 
road examples, the successive laminae were laid down closer 
together, and the shell itself would be proportionately thin and 
depauperated. 

This, together with another newly-described ornate species, 
P. 'producta, are among the commonest forms of the genus in the 
Victorian rocks. 

Affinities. — P. victoria' somewhat resembles the type of 
shell described under the name of P. muta by J. Hall,* from the 
Hamilton Group of the State of N. lork. P. muta differs, 
however, from our species in having the beaks decidedly anterior, 
in the extremely lamellose condition of the main concentric 
striae, and in the absence of the concavely depressed escutcheon 
in the posterior region. 

Horizon and Locality. — Silurian (Melbournian). From the 
Yarra Improvement Works, S. \arra, in blue and yellow shale, 
common; in the hard, dark shale of the Domain-road Sewerage 
Works at 103 ft. from surface, presented by Mr. F. P. Spry.

PalcBoneilo raricostce, sp. nov. PL III., Fig. 50. 

Description. — Shell of variable size, length more than twice 
the height, elongate-ovate, rostrate. Depressed convex. 
Umbonal ridge not strongly developed. Anteriorly broad and 
Avell-rounded, the margin meeting the cardinal line at an obtuse 
angle; posteriorly produced and sharply rounded. Cardinal 
line arcuate, straight between the vertical line and the posterior 
angle. Beaks depressed. Teeth of hinge characteristic, but 
comparatively large and few. Greatest convexity of shell- 
surface just behind the anterior umbonal slope. Shell orna- 
mented with well-marked lamelliform concentric varices, com- 
paratively widely spaced, the area between each being relieved 
by numerous thread-like striae.

Measurements. — Type specimen : Length, 21.5 mm.; height, 

9 nun.; number of coucentnc lamellar ridges measured over a 
^vidth of 4 mm. — 5. 

Observations. — The above species is recognised by its 
depressed valves, the somewhat acutely rostrate posterior 
extremity, and the comparatively wide interspace between the 
concentric ridges. 

Affinities. — This species also shows certain aHinitics with 
the previously-mentioned P. miifa, J. Hall, from the Hamilton 
Group of New York State. The rostrate extremity of P. 
raricostce and its depressed shape shows it to be specifically 
distinct.

Pala^oneilo spectabilis, sp. nov. IM. IIL, Figs. 51, 52. 

Description. — Shell of medium size, elongate ovate, 
rostrate; strongly convex in the umbonal region. Beaks nearly 
central, moderately well-inflated and gibbous. Cardinal line 
arcuate, gently curving to the broad anterior extremity. 
Ventral border straight, inclining posteriorly towards the 
cardinal line, and meeting the latter in a somewhat sharp curve. 
Umbonal slope forming with the median area a sinuous and 
obtuse ridge. Anterior slope gently convex. Teeth compara- 
tively stout, and not so numerous as usual in this genus; about 

10 on the posterior side of the beak. Surface having a series 
of concentric step-like folds and lamellar ridges, with com- 
paratively fine striae in the intervals between the ridges. 

Mea.'^urenients. — The type specimen: length, 28.5 mm.; 
height, 11.5 mm.; depth of valve, about 4 mm. 

Observations. — This species is distinguished from P. vic- 
torice by its umbonal convexity and consi)icuously rostrate 
outline. It is also a much heavier shell, and the groove for the 
external ligament is more distinctly seen.

SILURIAN BIVALVED MOLLUSCA OF VICTORIA. 



Palwoneilo j)roducta, sp. nov. I'l. III., Figs. 53, 53a. 

Descri'ption. — Shell small, ovate, very long, length more 
than twice the height; posteriorly attenuate, almost rostrate. 
Cardinal line only slightly arched, ventral border gently 
rounded, and curving upward toward the posterior end, then 
abruptly forward, meeting the cardinal line at an obtuse angle; 
well-roiinded anteriorly, and curving boldly To the cardinal line. 
Beaks acuminate and salient, nearly central. X'alvcs depressed- 
convex below; highest in the middle and at the umbonal region, 
sloping steeply towards the front, and gently to the posterior 
extr-emity, except where interrupted by the umbonal ridge and 
sulcus; the latter is rather feebly developed, and is parallel with, 
and in front of, the posterior umbonal ridge. Shell surface 
marked with very fine, regularly concentric striae, about 12 to 
the millimetre, counted on the middle of the shell below the 
umbonal inflation. 

Measurc7nents. — Type specimen : Length, 15 mm. ; height, 
6.75 mm. ; depth of valve, about 2.5 mm. 

The average length of the larger number of specimens found 
is 11 mm. 

Affinities. — This species shows a certain relationship to 
PalcBoneilo elongata, J. Hall,* from the Chemung Group (Upper 
Devonian) of the States of New York and Pennsylvania. 'the 
points of difference, however, are these : — 

The present species has more acuminate beaks. 

It is proportionately more elongate. 

The cardinal margin is less arcuate. 

The surface striee are finer and more than twice as 
numerous. 

Horizon arid Locality. — Silurian (Melboiirnian). Common

SILURIAN BIVALVED MOLLUSCA OF VICTORIA. 

Observations. — Our figure is drawn from a cast of a nucu- 
Inid shell which, b)^ its depressed umbo, apparent absence of a 
ligaiiioiit-pit and constricted jiosterior angle, Tails into tiic 
genus Palcponei/o as defined bj^ J. Hall. The present specimen 
IS exactly coni])arablo in outline with Conrad's figuic of P. con- 
stricta, and it further shows a characteristically large posterior 
adductor impression. Tn the absence of external ornament 
there is some slight doubt as to its specific identity. 

This species ranges through the Devonian of North 
America. 

Horizon and Locality. — Silurian (Melbournian). In the

p. 342, PI. L., Figs. 24-33. 

Observations. — Our specimen is comparable with the above 
form in having a short, ovate valve, ornamented with fine con- 
centric strine. The posterior margin is not perfect, but the 
depressed surface in front of the umbonal ridge is sufficient 
indication of the presence of a constriction on the basal margin 
of the shell. In the absence of more perfect specimens 
it will be safer to indicate the species with some reserve. J.

Observations. — Our figure is taken from a wax squeeze of 
a mould of the external surface of shell. In the regularly and 
finely striate surface, and the obovate form of the valve it can 
be closely compared with J. Hall's species cited above. The 
strongest points of difference are, the obsolescence of the postero- 
umbonal sulcus in our form, and the central position of the 
beaks, although one example figured by Hall approaches ours 

[ 37 ]

very closely in this respect. The Victorian specimen may also 
be compared with P. fecunda, J. Jlall,* althouf^h that species 
has a marked depression in front of the umbonal ridge.

Family Parallelodontidae. 

Genus Parallelodon, Meek and Worthen, 1866. 

Parallelodon spryi, sp. nov. Plate I., Fig. 3. 

Description. — Shell of medium size, subovate; cardinal line 
nearly straight, meeting the posterior border almost at right 
angles, but slightly upturned; ventral border convex, narrower 
anteriorly, and broadly curved posteriorly. Median area 
swollen, rising prominently towards the beaks, which are 
situated sub-anteriorly; posterior region compressed. Cardinal 
area exposed in the type specimen, showing what appears to be 
the extremity of a series of about six parallel and slightly 
oblique hinge-teeth. Surface of valves grooved concentrically, 
the highest part of the ridges being obliquely striated, the 
stri« radiating from the beaks. Indications present of a large 
anterior muscle impression situated close to the cardinal area. 

Measurements. — Length, about 26 mm.; height, 17 mm.; 
thickness of entire shell, 8 mm. 

Observations. — The presence of a parallel series of anterior 
teeth points to relationship with Parallelodon, sensu stricto. 
The genus Macrodon, Lycett, 1845 (nom. emend. Macrodns. 
Beushausen, 1895)t is closely allied, and is regarded by Dall]; 
as synonymous. The latter genus differs in some slight respects, 
such as the obliquity of the anterior teeth. Should both types 
prove to be congeneric, the former name will stand, since the 
latter had been used by J. Mliller for a genus of fishes, whilst 
Beushausen's name is of much more recent date.

Parallelodon ccqualis, sp. nov. Plate IV., Fig. 57. 

Description. — Shell small, elongate oval, rounded and con- 
stricted in front, broader and truncated behind, with a sharp 
unibonal ridge extending from the umbo to the postero-ventral 
margin. Beaks sub-anterior, or nearly central, inflated and 
directed forward. Cardinal line straight; ventral border 
slightly curved and approximately parallel with the hinge- 
line. Three posterior, oblique, lateral teeth visible behind the 
beaks, and close to the cardinal border. 

Measurements. — Length, 12 mm.; height, 7.5 mm.; depth

species differs from ours in the more extended posterior, and in 
the strong concentric surface ornament; McCoy's species may, 
however, eventually prove to be more nearly related to the 
North American Devonian types of this genus.

vertical depression from the beak towards the ventral margin. 
Cardinal line long and straight; cardinal area compressed in 
front and Ijehind. Surface marked with fine concentric lines of 
growth, which become lamellose in the cardinal area. 

Measurements. — Length, 16 mm.; height, 14 mm.; depth 
of valve, 3.5 mm. 

OhservafAons. — This species is referred to the genus 
Parallelodon with some reservation, since the hinge structure is 
obscure. The evidence tends, however, in the direction of this 
genus, for the beaks are not closely adpressed, and the cardinal 
area is lamellose, as in typical forms of Paralleloclon, pointing 
to the former presence of an external and amphidetic ligament. 

The specimen figured on PI. VI., Fig. 4, although at first 
suggestive of TeUinoj^sis, is apparently referable to this species, 
possessing the lamellose cardinal area and traces of teeth.

Observations. — There is very little doubt that the imperfect 
valve figured under the name of Ambonychia tatei by the Rev. 
A. W, Cresswell is an example of Pterinea lineata, Goldfuss. 
Fragments of the above form are fairly common at some 
Yeringian localities east of Melbourne, and it seems to be a 
characteristic form in the uppermost Silurian beds in Victoria

Ludlow beds; in Germany it is a well-known Devonian fossil.

Ptennea temiistriata, McCoy, 1852, Brit. Pal. Foss., p. 263,

Observations. — The Victorian example shows very little 
diflcrence from McCoy's figured specimen; tlie chief distinction 
being the acute form of the ears, a character which is not sufh- 
ciently important to justify its separation from the British 
species. Were there other specimens for comj)arison it is prol)- 
able that we should find more tyi)ical examples among.st them. 
The general form and surface ornament is simihir to the British 
species. It has been recorded in Britain from the Wcnlock and 
tJie Lower and Upper Ludlows. This species is doubt- 
fully referred to the genus Pterinea, as further examples may 
show that both McCoy's and our specimens are really referable 
to Actinopteria.

sub-anterior, incurved, with an external ligamental groove 
situated in front of the beak. Anterior border narrow; 
posterior broad, gently curved and sub-truncate. Surface

Observations. — The above fossils, from the uppermost beds 
of the Victorian Silurian, at first glance present little difierence 
from those figured under the name of ? Cardium striatum bv 
Sowerby.* A minute inspection of a fairlv long series of Aus- 
tralian specimens shoAvs, however, that, although closely related 
to Sowerby's species, their costulfe are less numerous and more 
distinctly medially grooved, especially towards the ventral 
margin of the shell, and also that the concentric folds are much 
more pronounced. Our species is more oblique than that figured 
by Sowerby, and in this respect they agree more closely" with 
the variety mentioned by that author, from Brindgwood Chace 
floe, cit., p. 614). A specimen of the Dudley shell in the 
National Museum collection shows the multisfriate character of 
the externa] surface very clearlv, and that the riblets or strife 
tend to become medially grooved near the ventral margin. The 
related British species ranges from the Bala beds to the Lower

From the Tentaculite slates (G^) of Bohemia, Barrande has 
described LunuHrardiiiin graniilosuin, which, althougli a more 
depressed shell, is closely related to our species, more especially 
in the granulose ornament of the shell surface.* 

In the shaly mudstone from the mouth of Starvation Creek 
there also occur numerous small bivalves (Figs. 64, 65), which, 
on first examination, might reasonably be mistaken for a species 
of Vlasta; in its superficial character and general form, however, 
it corresponds very closely to the prodissoconch and early disso- 
conch stages of Lnniilicard'mm antistriatum. In connexion

curved and meeting almost at right angles; posterior margin 
truncate and broadly curved. Beaks acuminate, curving 
sharply forward. Cardinal grooves presenf on the anterior

Pleurorhvnchus helhtlus, Cresswell, 189:3, Proc. Roy. Soc. 
Vict., Vol. V.', N.S. p. 43, PI. IX., Fig. G. 

Observations. — This species is dis'tiuguislied from the 
rarer form which accompanies it, by the more numerous costae, 
which are typically lamcllated or even squamose, by the greater 
obliquity of the umbonal ridge, ami by its generally smaller 
size. 

Affinities. — The nearest described form to C. bellulum is 
Salter's species C. dipterum* from the Upper Ordovician (Bala 
beds) of Ayrshire, Scotland. In this species, however, the 
umbonal ridge and the costae are not so oblique nor so strongly 
curved. 

C. bellulum also shows some alliance with Conocardium 
cuneus, Conrad sp. var. nasuta, J. Hall,t a fossil which occurs 
in the Helderberg series of New York State.

specimen was found by the Rev. A. W. Cresswell at Cave Hill, 
Lilydale. It is also an abundant species in the dark-blue lime- 
stone of Deep Creek, a tributary of the Thomson River, Gipps- 
land, 7 miles N. of Walhalla. Specimens from the latter locality 
were presented to the National Museum by Mr. Cresswell. In

Devonian iauna (Pal. Soc. Mon.), p. 74, PI. IX., Figs. 2, 2a, 'S, 
3a, 5-7. 

Observations. — This is an oblique shell with an unusually 
deep left valve. The ornament is very distinct from the usual 
type in this genus, consisting of a series of rounded radial rib- 
lets crossed at varying intervals by moderately thin undulating 
laminae, and this gives to the shell-surface a woven appearance. 
The only difference between our form and already described 
specimens is the convexity of the posterior wing of the 
left valve, which, however, seems to be a minor character. 
An extraordinarily large specimen, which may belong to this 
species, occurs in the present series; this specimen shows a 
tendency in the gerontic stage to throw off irregular concentric 
laminae on the shell-surface, instead of regular, rounded 
threads, whilst the radii become almost obsolete towards the 
ventral margin. 

The previously-recorded examples of Actinopteria texturata 
were from the Devonian, of Devonshire, England; the occurrence 
of Victorian specimens thus extends its range both from a geo- 
graphical and geological point of view. 

This figured specimen is probably that referred to by Mr. 
Cresswell as " Pterincea sub-falcata, or an allied species."* It 
differs from Conrad's sitb-falcata in the character of the ribs, 
which in that species are not crossed by intermediate threads.

Obsercations. — This very handsome species, although 
variable, is sufficiently distinguished by its characteristic radial 
and concentric ornament; the concentric laminae are undulose 
and concave between the rays, meeting the latter in a more or 
less sharp point. The edges of the concentric lamellae are often 
so pronounced as to give rise to a series of scalloped frills. The 
areas cut oft' l)y the concentric lamellae are usually much higher 
than broad. 

This species occurs in the Upper Ludlow in Britain, at 
Kendal, in Westmoreland. In N. America it is abundant in 
the shales of the Hamilton Group in New York State.

Pterinea sowerbii, McCoy, 1852, Brit. Pal. Foss, p. 263. 

Observations. — The Victorian specimen is represented by 
an imperfect mould of the shell, and a wax impression of this 
shows it to be closely allied to the above-named species. The 
ornament of lamellated concentric fohls, and the interrupted 
radii, together help to support this identification. Until better 
specimens have been discovered, however, it is safer merely to 
point out its relationship with the British fossil, which has been 
recorded as ranging from the Upper Llandovery to the Aymestry 
Limestone. 

There is another species to whicli our shell bears some 
resemblance, namely, " Pterinea " lamellosa, Goldfuss,* but the 
radial ornament of the latter is much more strongly pronounced 
than in our specimen. Goldfuss' species is a typically Devonian 
shell, and has only been doubtfully recorded from the Wenlock

SILURIAN BIVALVED MOLLUSCA OF VICTORIA. 

The original is an impression of a left valve in blue mud- 
stone, and the drawing has been made from a well-defined cast 

in wax. 

Observations. — The above fossil is a typical Aviculopecten, 
in accordance witli the emended definition of the genus given by 
J. Tlall,* since it has a short hinge-line and well-defined ears. 

Horizon and Locality. — Silurian (Melbournian). Yarra

Family Modiolopsidae. 

Genus Modiolopsis, J. Hall, 1847. 

Modiolopsis melbournensis, sp. nov., PI. V., Figs. 76, 76a. 

Description. — Shell small, sub-quadrate, elongate, com- 
pressed posteriorly; length rather less than twice the height. 
Cardinal line nearly straight; ventral margin parallel. 
Anterior extremity narrowly rounded, and incurved under the 
prominent sub-anterior beaks. Posterior extremity broadly 
rounded, and meeting the hinge-line at an obtuse angle. 
Umbonal ridge extending from the beaks to near the postero- 
ventral angle. Greatest convexity of surface in the umbonal 
region; ventral area somewhat depressed. Surface marked by 
fine, irregularly concentric growth-lines. 

Measurements. — Length, 16 mm. ; height, 9 mm. 

Affinities. — A form nearly allied to the above is Modiolopsis 
solenoides, Sowerby, sp.t, from the Upper Ludlow, near Bridge- 
north, England. It differs from our species, however, in its 
greater compression, less prominent beaks, and in having a 
broad median depression in the ventral region.

Observations. — The Middle Devonian I'ossil identified by J. 
Phillips* as f PuUastra complanata, 'Sowerby, is distinct from 
the Sihirian fossil, and is not related to Mudiulupsis, since the 
posterior cardinal area is not compressed nor expanded, whilst 
the beaks are not situated so far forward. The Victorian 
specimen agrees in almost every detail with Sowerby 's species, 
which in Great Britain occurs in the Weiilock, the Upper 
Ludlow, and the Tilestone Series. 

Measurements. — 'ihe Victorian specimen has a length of 
18.5 mm.; height, 11 mm. 

Horizon and Locality. — Silurian (Melbouniian). This 
striking species was found by Mr. F. P. Spry in the blue mud- 
stone of the Van-a Inipioveinoiit \\'oiks, S. Vaira, and pre- 
sented by him to the National Museum. [7942.]

Observations. — Those elongate and modioli form shells 
which have no sharp posterior urabonal ridge, and in which the 
cardinal line is more or less curved, may be justifiably sejiaralcd 
from the genus Orthonota. as now understood, and jilaced witji 
Modiolopsis (as restricted by McCoy). t The above shell is an 
example of such, which, although not so strongly arched in the 
uinbonal region, yet seems to possess all the essential chaiacters 
of Hall's genus. 

It is interesting to note that the specific form is widely 
distributed, and there seems no reason to doubt that the Aus- 
tralian example is generally comparable with both the N.

American and Britisli specimens. The previously-recorded 
horizons for the specific form are at the top of the Ordovician 
(Hudson 1 liver Group and the Caradoc series). 

The present variety is distinguished from the type species 
by its shorter and stoutei- for'm, and less pronounced nasute 
anterior extremity.

Genus Glossites, J. Hall, 1885. 

Glossites Victoria;, sp. nov. Plate VI., Fig. 79. 

Description. — Shell small, compressed, elongate ovate, 
narrow in front, broad behind. Hinge line slightly curved. 
Beaks sub-anterior, depressed. Posterior margin strongly 
curved; ventral margin gently curved and truncately rounded 
at the anterior extremity. Umbonal convexity gradually be- 
coming more depressed on approaching the postero-ventral 
margin. Shell texture thin; surface concentrically wrinkled 
with irregular lines of growth. 

Measurements. — Height, 9.5 mm. ; length, 16.5 mm. ; depth 
of valve at umbo, 3 mm. 

Affinities. — The only form of this genus with which the 
above species can be at all closely compared is G. depressus, J. 
Hall,* from the Chemung Group of Ithaca and Elmira in the 
State of New York. That species, however, has a more gener- 
ally depressed shell, and the beaks are more acute.

Genus Goniophora, Phillips, 1848. 
Goniophora australis, sp. nov. PI. VI., Fig. 80. 
Description. — Shell sub-ovate, elongate; length about 
twice the height. Beaks large and anterior, strongly incurved 
toward the ventral margin. Anterior extremity of the shell 
narrow, very broad behind. Umbonal ridge prominent and 
sharp (in the type-specimen the posterior extremity of the shell 
is lient forward against the umbonal ridge). Basal edge 
sinuously curved; rising up to, and terminating just below, the 
beaks, at a sharp angle. Surface ornamented with numerous 
bifurcating lines of growth.

Observations. — Our specimen is imperfect, but the anterior 
and most characteristic part of the shell is represented. 

The habit of the shell is short. The surface is finely 
striated, and the striae turn up at a steep angle over the um- 
bonal ridge; this latter feature itself indicates a short form. 
The beaks arc small and strongly incurved, whilst the umbonal 
ridge is sharp and widely curved. Hall's specimens came from 
the Hamilton Group of New York State.

(Jypricardinia nitidula, var. contexta, Barrande, 1881, 
Syst. Sil. Boheme, Vol. VI., Pt. I., PI. 257, Fig. IV., 19-24. 

Observations. — Barrande's Cypricardinia nitidula is pro- 
bably the same form as (J. plannlata, and it therefore falls into 
the synonymy of the latter species. The variety contexta of the 
same author, however, is undoubtedly similar to some of the 
British fossils described by Salter under Conrad's name of C. 
planulata, but from which they differ in having a secondary 
iuterlamellar ornament. The Victorian specimens show the 
striae to be often arranged in chevron fashion, and a tendency 
in this direction is indicated in one of Salter's figures (Fig. 
4, loc. cit.), shown by the peculiar twist of the radii. The 
Bohemian, British and Victorian fossils, having a similar 
ornamentation, may perhaps be more conveniently referred to as 
Cypricardinia contexta, Barrande. The British examples of C. 
contexta were described by Salter as being pretty generally dis- 
tributed through the Wenlock and L. Ludlow series, where it 
appears to be associated, as in Bohemia, with C. planulata. 
The Bohemian examples are recorded from Stage Ffj, which 
by Kayser and others is now considered to be Lower Devonian, 
although formerly placed in the Silurian. 

Another striated form of the same type of shell as the above 
is to be found in Sandberger's C. crenistria* represented by the 
more highly convex right valve. In this species, however, the 
striae are essentially regular and radial.

SILURIAN BIVALVED MOLLUSCA OF VICTORIA. 



Ornamented \vith concentric rin>;s of growth, appearing as 
irregular folds, and most strongly marked near the extremities. 
All the examples known at present from Victoria are in the 
form of sandstone casts, so that the finer markings, if any, have 
perchance been lost. In wax squeezes taken from these casts 
there seem to be faint traces of a feeble radial, linear sculptur- 
ing, such as is seen in Paracyclas Unentn, Goldfuss sp.*, which, 
by the way, our species otherwise resembles, with the exception 
that the latter is more regularly convex over the whole surface. 

Mensiirements. — Figured specimen: Length, 15.5 mm.; 
height, 15.5 mm.; depth of valve, ;}.5 mm. 

Observations. — The present species resembles McCoy's 
Anodontofsis bulla] in its general shape, b\it differs in the 
coarser sculpturing of the shell-surface. The .1. bulla, McCoy, 
does not appear to show- any decided affinities wdth the other 
species described under the generic name Anodonto [jsis by 
McCoy, and seems to be a typical example of the earlier 
described genus Paracyclas. 

It is of much interest to record that McCoy indicated the 
actual specimens with which I am now dealing as " a new form 
of Anodnntopsis allied to .1. bulla," by a pencil note written on 
the tablet of a mounted series in the Museum. The generic 
name Anodontopsis, besides being ante-dated by Paracyclas, 
appears to embrace three generic types as exemplified by 
McCoy's published species in his "British Palaeozoic Fossils," 
as follow : — 

Anodontopsis bulla, McCoy ^ Paracyclas, J. Hall, 1843. 

A. anrfustifrons, McCoy = Modiomnrpha, J. Ifall, 1870. 

A. quadratus, McCoy ^Cypricardella, -J. Hall, 1856 
(Microdon. Conrad, 1842 — pre-occupied by Agassiz's genus). 

Another species which may be cited for comparison with 
ours is Paracyclas rlliptica, J. Hall.| from the Corniferous 
Limestone and the Hamilton (h'oup of the United States and 
Canada. It is, however, not so high, and the lirfc are more 
distinct and more closely set.

86, 86«. 

Descriftion. — Suborbicular, rounded in front, subtruncate 
behind Beaks central, salient and snbacuminate. sharper than 
in the preceding species. Valves strongly convex, esi)ecially in 
the umbonal region, where they become almost ridge-like; super- 
ficial markings in the form of fine concentric striae. 

Measurements. — Length, 13.5 mm. ; height, 13.5 mm. ; depth 
of valve, 4 mm. 

Observations. — This variety presents marked differences 
from the foregoing species, but in view of the fact that only 
a single example has occurred up to the jDresent, and in associa- 
tion with the specific form, it will be safer for the present to 
regard it merely as a variety. In common with the type form, 
the figured specimen shows obscure indications of a radial 
lineation of the shell.

King Island lies at tlic western entrance to Bass Strait, almost 
midway l)etween Victori.i and Tasmania. A line of soniiding, 
between the island and Tasnumia. as laid down in the Admiralty 
charts, shows an averas^e depth of thirty-two fathoms. The 
lowest is twenty, tlu' hi<i;hest forty-four, and the great majority 
range between tiiirtv and thirty-Hvo fathoms. A line between 
King Is! ind and Cape Utway, on tlie Victorian coast, averages 
nearly forty-eight fathoms. The lowest is thirty-nine, the highest 
fifty-five. 

The date of the formation of Bass Strait is a matter of doubts 
but it may in all prol)al)ility be assigned to the Post Pliocene 
period.* 

The I'auna of Tasmarna differs from that of Victoria partly in 
the absence of certain animals, sncli as the Dingo ( C.////.V dintio) and 
the Hying phalangers amongst the marsupials, and partly in the 
presence of otiiers. snch as Thylacinns ami Sarcophilus, which 
are nowe.\tinct on the mainland of Australia. Such dilferences as 
e.xi.st between the fauna of Victoria, south of the Dividing Range, 
and that of Tasmania, may be regarded as due to the formation of 
Bass Strait, which resulted, during comparatively recent times, iu 
the separation of Tasmania from the soutli-east part of Au.stralia. 
Some idea of the nature of the land briilge that oinc stretched 
across between Victoria and what is now the islanil of Tasmania 
can be gained from a study of its remnants, as revealed to us in 
tlie chain of islands that stud both the western and the eastern 
margins of Bass Strait. Tiie central part of the strait is open 
water, but on the eastern side a chain of islands, consisting in the 
north of smaller groups, snch as the Curtis and Kent, and in the 
south the larger Kurneanx group, lead across from Wilson's I'ro- 
montory on tJie mainl.md to the north-east corner of Tasmania. On 
the west there is King Island, and close to the north-west point of

SUB-FOSSIL REMAINS FROM KING ISLAND. 



TasniMuiii a group of smaller islands — Iluntor Islands and the Hum- 
mocks. Between King Island and Cape Otvvay lies open water, 
with a curious and well-marked di])piiig invading the fifty fathom 
linei indicating in all prol)al)ility the foi-mer existence of the 
estuary of a large stream that once ran southwards from the Vic- 
torian ranges. We may therefore safely conclude that the old laud 
bridge was traversed in its north-western part In- a i-iver of con- 
siderable size, that its central part was comparatively low land,* 
and that this was bordered on the east by a chain of lofty hills. 
Across this central part a river ])rol)ably ran northward to join the 
one flowing southwards near its estuary. On the western side, to 
the south of the estuary, was high ground, part of which is now 
represented by King Island. 

In the early days of Australian settlement a few sealers and 
fishermen frequented King Island, but for long years it was practi- 
cally deserted until, about thirty or forty years ago, an attempt was 
made to utilize it as a sheep run, but the e.xistence of the poison 
weed {Swain sonia lesser ti folia) proved fatal to the scheme, and once 
more the island was abandoned. In November, 1887, the Vic- 
torian Field Naturalists' Clul) organized an expedition to the 
island. Its onlv inhabitants at that time were the lighthouse- 
keepers at Cape Wickham and Currie Harbor, and one solitary 
wallaby hunter. We had con.siderable difficulty in traversing the 
island, owing to the fact that its northern half was covered with 
dense scrub, and its southern part with impenetrable forest. During 
recent years the island has been occupied again, much of the 
scrub has been cleared away, and parts previously inaccessible 
have been opened vip. (In one occasion a large flock of sheep was 
placed on what is now known as the "sand patch." near to Stokes 
Point, the exti'eme south-western promontory of the island. At 
that time this particular part of the island was covered with grass, 
but the sheep eat this down to the roots, and, later on. " numbers 
of pigs, rooting about, turned up the soil and started a sand-blow, 
which now extends over some hundreds of acres. iliere is a 
dividing ridge running the length of the patch, and the sand shifts 
from one side of the ridge to the other with every change of ^nnd. 
It was during a strong westerlv gale that 1 rode down 

to Surprise Bay Every few yards lay the bone of 

some animal in a more or less perfect state of preservation, and 
here and there the ground was covered with the petrified stumps 
and roots of old scrubs."f 

The fact of the existence of these sub-fossil remains became 
known to Mr. H. H. Scott, the Curator of the Victoria Museum, 
Launceston, who placed himself in communication with Mi*. J.

SXJB-POSSIL REMAINS FROM KINO ISLAND. 



McKie Bowling, the proprietor of that part of the ishmd, and was 
instrumental in secnrinij the Hrst collection that was made. A 
short time afterwards Miss Dickson, of Ilobnrt, visited the island, 
and was shown the fossil remains hy Mr. Bowlins^. ( )n her return 
to Hol)art Miss Dickson l)rouL>lit the matter under the notice of 
the IJoval Society of Tasmania, with the i-esult that Mr. R. M. 
Johnston and the late Mr. Ale.x. Morton went across from Laun- 
ceston, and, through tiie instrumentality of Mr. Bowling, were 
able to secure a series of s])eciniens, which thev kindly placet! at 
our disposal for description. This collection included a consider- 
able number of bones of an Emu, and, after a careful examination 
of the latter, they were described as the remains of a new s])ecies, 
to which the name Dmmceiis minnr was given.* 

The collection received from Messrs. Johnston and Morton 
included also skulls of a Wombat and Dasyurus, and, in view of the 
importance of the remains as indicating the e.xistence in the islands 
of Bass Strait of animals, such as an Emu and a Wombat, distinct 
from those of the mainland and Tasmania, we thought it advisable 
to make further investigations, and, accordingly, one of us (J. A. 
Kershaw) went across to King Island, and spent some time there 
carefully collecting as much material as was available. Most 
fortunately for us Mr. Bowling was much interested in our work, 
and afforded us the most generous assistance, without which it 
would not have been possible for us to secure the large series of 
specimens that we now possess, and we take this opportunity of 
thanking Mr. Bowling for his invaluable aid. 

The n-mains were chiefly distril)uted over the sand dunes on 
the e.\trenie southern portion of the island. f The area covers 
some 300 acres in extent, and consists of a series of small 
ridges, the highest of whic-ii is on the south-east point. The sand 
is constantly l)eiiig blown from one side or the other of these ridges, 
and the bones alternately ex])Osed and cnvered. During the strong 
winds wlii<di prevail these are sifted out in considerable numbers, 
and lie distril)uted along the sides and in the trough of the ridges 
Portions of the skulks, lower jaws, and limb bones of Wallabies 
were found mixed up with the leg l)ones of the Emu, skulls of 
Wombats ami Dasyures, and here and there portions of the 
skeletons of bolh Seals and Sheep. Wallabv remains were l)v far 
the most numerous, and, though e\tremely fragile, fairly complete 
skulls could l)e ol)tained. Portions of the lower jaws were scattered 
about in large numi)ers along the sides of some of the ridges, which 
had recently been exposed to the action of the wind.

these dunes.

SUB-FOSSIL REMAINS FROM KING ISLAND. 



Emu remains were scarce. Every l^oiie that would Ijear 
liandlino' was coUfrtod. Very dillii^ent search was made for any 
portions of the skull or sternum, l)ut although the whole area wa> 
carefully examined several times, l)ut few fragments of skulls or 
sterna were found. Very incomplete portions of the sternum were 
occasionally found imbedded in the firmer soil iKueath the sand, 
but every attempt to remove them resulted in their crumbling 
away. The remains of the eggs were frequently met with either 
in small fragments in tlie loose sand, or in patches imbedded in the 
firmer soil beneath. In one or two instances fully half the shell 
was found completely flattened out and fractured into small frag- 
ments, with the surface more or less removed by the action of the 
driving sand. 

Exposure to the sun and rain had rendered many of the bones 
extremely fragile, so that when distiirbed, however carefully, they 
broke into small fragments. 

Fairly comjilete skeletons of Wallabies and one or two Emus 
were found lying in the more compact soil beneath the sand, but 
the most careful attempt to remove them again resulted in failure. 

Although most of the remains were found on the extreme south 
point of the island, they were also met with on several parts of the 
west coast wherever a sand blow had started. Bones ot Wallabies, 
Wombats, Emus, and Dasyures were found fairly numerous on an 
extensive sand blow near the Porky River, some 6 miles north of 
Currie Harbor. These were, however, less complete and nmch 
more fragile than those obtained from the south. That so many 
bones should be gathered together in one spot is doubtless to be 
attributed to the fact that in the early days, before the advent of 
the white man with his sheep, this area was one of the most fertile 
spots in the island, and was probably a much freqiu'uted and 
favourite feedina; g-round. 

The collection contains remains of the following animals : — 
1. Dromaeus minor. Spencer. 
•2. *Tachyglossa aculeata, var. setosa. Shaw. 

3. *Macropus billardieri. De.sm. 

4. *Macropus ruficollis. Desm.

7. Phascolomys ursinus. Shaw. 

8. *Phascologale minima. Geoff. 

9. Dasyurus bowlingi. Sp. n. 
10. Mus sp. 

Of these animals the six marked with an asterisk form part of 
the present fauna of the island, but their l)ones are intermingled 
under the sand dunes with those of the other three that are now- 
extinct. We will deal at further length with these three.

SUB-FOSSIL REMAINS FROM KING ISLAND. 



Dromjeus minor. 

The original discovery of an Emu on the islands of Bass Str.iit 
was made in 1 802. Tn December of that year Admiral Baudin in 
his e.xploring ships Gio<irnphe, Xnfurulisfe, and Casunri/iii vi.sited 
Kangaroo Island, so named 1)V Flinders, though Baudin. unaware 
that ho had been forestalled by the Enalish navigator, called it 
lie Decres. I'eron described the existence of large troops of 
Enuis there. Three of them were brought back alive to Paris. 
( >ne went to the Jardin des Plantes and two to the Chateau of 
Malmaison. The latter evidently found their way eventually to 
the Museum, as Viellot speaks of several Emus of small size livins: 
at his time in the Jardin des Plantes. The Museum now 
possesses two specimens*, (I) a skeleton labelled " Casoar de la 
Xouvelle Ilollande, mort a la Menagerie en Mai 1H22, de I'ile 
King, par I'eron et Lcsueur, expedition du Capitaine Baudin," (2) a 
stuffed specimen labelled " Drontaii/s ater \'., Port Jackson, 
Australie, ex])cdition du ("apitaine Baudin." and bearing this 
further reniarkalde legend, " Casoar de la Nouvelle Hollande. 
< 'nsKfii 'nta Jus/ni/is, Lath . rapporte vivant de Port Jackson par 
I'cxpcdition du Capitaine Baudin, mort en avril 1822 — Le s(juelette 
est a I'anatomie." As Milne Eldwards and < )nstalet point out, the 
stuffed specimen certaiidy contains some hones, and as the 
skeleton in the gallery is complete the two specimens must repie- 
.sent parts of at least three birds. However tiiis may be, both 
specimens certainlv came from Kangaroo Island, and from neither 
King Island nor I'nrt Jackson. The mistake with ivgard to King- 
Island is all the more curious, because during Baudin's expedition 
the naturalists Leschcnault. Baillv. Lesueur, and Peron were left 
stranded at Sea Elephant Bay, on the east coast of King Island, 
a strong gale forcing the ships to stand off from the land. Fortu- 
natclv for them, thev came across a few sealers who had settled in 
this out-of-the-way spot. The chief man anu)ngst them, named 
Cowper, entertained the French naturalists in his quarters, and in 
addition to actually seeing two " Casoars " hanging up in his larder

its lieia:ht was 4^ ft. — that is less than the iiiaiiiland form — it 
weighed 40 lbs. to 50 lbs. ; the male was slightly larger than the 
female, but there was not much difference; and. finallv, Cowper 
informed his catechist that he had himself killed no fewer than 
300 birds. 

It is rather curious that the naturalists appear to have con- 
tented themselves with questioning Cowper, and apparently made no 
attempt to capture a specimen, which would have been a mu(di more 
satisfactory manner in which to determine the nature of the bird. 

For mauv vears sealers and fishermen frequented King I.sland, 
and if manv of them followed Cowper's e.xample in regard to his 
wholesale slaughter oi' the bird, as doubtless they did, it is not at 
all surprising that the members of the Field Naturalists' Club, 
who visited King Island in 1887, found not a trace of the Emu at 
Sea Elephant Bay on the very spot where, eighty-five years 
earlier, the French naturalists liad questioned Cowper. 

In addition to the collection secured by Messrs. Johnston and 
Morton we have the extensive one made by one of us. and ^Ir. H. H. 
Scott, Curator of the Victoria Museum in Launceston, generously 
placed all of his material at our disposal. We have been in firequent 
communication with Mr. Scott, who has assisted us in every 
possible wav, and we desire to record our special thanks to him. 

The whole collection, upon which the following account is 
based, contains, apart from many others that evidently belong to 
decidedly innnature birds, the following bones : — 

1. Sixty-four femora. 

2. Forty-one tibio-tarsi. 

3. Seventy tarso-metatarsi. 

4. Four pelves of which the total length can be measured, 

and parts of sixteen others. 

5. Parts of six skulls. 

6. One pectoral arch. 

7. Portions of three sterna. 

8. Fourteen fibulae. 

9. Ribs. 

10. Vertebral bodies. 

11. Toe bones. 

1. Femur. 

(Plate 2.) 

The sixty -four femora vary in length from 186-130 mm. 
A mature D. nuvce-liollmidke measures l'38 mm., and the length 
of that of D. pernni ( = D. afe?-) is given as 180.* 

• In his work on " Extinct Birds," (p. 235), the Hon. Walter Rnthschild points out that 
Vieillot applied tlie specific name ater to Latham's Caxuarius iiovce-hollanditi, and also that 
the same author makes no mention of P^ron or^the ile Decr^s. Mr. Rothschild has, therefore, 
proposed the specific name peroni for the extinct Kangaroo Island bird.

Of the two lon<rest, one measures 186, the other 180, hut 
as will be seen, the uieat in.ajoritv lie I)et\veen 150-180. The 
collection eviduutly includes bones of birds of different ages, as the 
smallest ones (not included in the table) only measure 110 mm. 
Almost everyone of those included in the table would, however, if 
found separately, be regarded as the bone of a well -developed 
bird. How far differences in size are sexual as well as age 
characteristics it is impossible to say, but when questioned by the 
French naturalists, Cowper, the dshernian, said that though the 
male was the larger the difference in size was not considerable. 
He also said that the l)ird reached maturity in one year. We 
may probably regard the two larger ones as decidedlv above the 
average size of a mature bird, the femur of which would be more 
nearly 170 than 180 mm. So far as the structure of the bone is 
concerned, there is no difference save size between it and the 
corresponding bone of D. novce-liollnndice. 

2. Tibio-tursus. 
(Plate 3. Figures 1-10.) 

The whole collection includes 75 examples of this bone. The 
41 that are included in the table of measurements varv greatlv 
in length. In the original description the greatest length was 
given as 332. Out of the limited number then collected onlv 
two exceeded .'320. In the large collection now available there 
are only four of this size, and they measure respectively 363 mm.* 
(?), 3.J4 mm., 332 mm., and 328 nun. The general results of 
the measurements is given in the followinu; table : —

It will be noted that two out of the series exceed by 23 mm. 
and 14 mm. resjiectively the length of the specimen of D. pernni 
in the Paris Museum. The number of specimens of the latter 
species that have l)een ])reserved is unfortunately so small that it 
is impossilde to judge of the amount of variation in the size of the

SUB-FOSSIL REMAINS FROM KING ISLAND. 



bird. That considerable variation did exist is almost certain, 
judging- from tlie measurements oi' adult mainland and King Island 
forms. Out of" 42 a|)parently mature bones of the King Island 
bird, that is, bones in which the tibial and tarsal elements are firmly 
ankylosed, it would be rather curious not to find more than two 
representing those of normal full-sized birds, so that we are prob- 
ably safe in concluding that these two especially long bones 
represent birds of abnormal size.* 

We are inclined to think that the length of an average-sized 
mature male is between 3(10 and 3-0; that those in the table above 
this are exceptionally large specimens; that the large number 
measuring from 270-290 mm. in all j)robability are fully-grown 
females and males that are not fully grown. In the case of all 
those included in the 41 the bones appeared, however, to be 
mature, with the peroneal ridge well marked. 

For the sake of comparison we have illustrated both the til)io- 
tarsus of D. novce-hollandicB and that oi'D. peroni.^ The former is 
mature, and measures 440 mm. The latter is not mature, and 
measures only 270 mm. The Paris specimen measures 342. We 
have placed the Kangaroo Island tibio-tarsus by the side of a 
King Island bone of ap]n-oximately the same length. A compari- 
son of the two indicates the fact that the latter bird was evidently 
of considerably more robust build than the former. Messrs. Milne 
Kdwards and Oustalet sa\- that the til)ia in D. peroin is quite 
straight, in contrast to the slightly curved bone in D. iiovcb- 
hnllandice. In all tibio-tarsi from King Island, and in the 
Kangaroo Island bone, there is a slight but ciuite distinct 
curvature. 

3. Taiso-metd tarsus. 

(Plate 4. Figures 1-12.) 
The 70 specimens measured are not all of them mature 
bones. The lengths of those that are mature, that is, in 
which the tarsal element is lirndy attached to the end of the 
metatarsal element, the tubercle for the tibialis anticus well 
marked, and the foramen completely enclosed, varies from 210 mm. 
to 292 mm. The lai'gest presumably belonged to old males of 
exceptional size, the smaller to small females. On the other hand, 
there are quite immature bones measuring as much as 240 mm. 
in length. Out of the 70 specimens measured, one reached the 
length of 292 mm., J and four others the lengths respectively of 
278, 278, 277, and 271 mm. As shown in the tjible, the majority 
of measurements lie between 220 and 250 mm. There are 23 
between 230 and 240. and 12 between 220 and 230. and the same

SUB-FOSSIL REMAINS FROM KING ISLAND. 



The first portion of a pelvis secured was obtained bv Mr. 
Campbell, and presented by him to the National Museum. This 
by itself was too fragmentary and imperfectly preserved to base 
any decided conclusion upon. Indeed, in the absence of other 
specimens it could not be definitely stated whether it was an 
adult or a young one, but the structure of the 20 specimens now 
in onr ]jossession is decisive. As the table shows, there is a 
difference of 150 mm. between the length of the largest pelvis of 
D. minor and D. novce-hollandioe, and a difference of nearly 
50 mm. between the former and D. jjeru/ii. Indeed, the latter 
appears to be intermediate in size between the two former. 

5. Skull. 

(Plate 6.) 

As might be expected, remains of the skull are difficult 
to procure, and are of necessity more or less fragmentary, the 
fragile bones of the jaws being easily detached and broken. 
The complete fusion of the bones, and entire eradication of all 
sutural marks, show that the remains are those of quite mature 
birds; indeed, unless complete fusiou of the bones had taken place, 
there would uot be the slightest chauce of the preservation of the 
cranium as a whole. The shifting of the sand, under which the 
bones lie buried, by strong westerly gales would soon dissociate the 
skull bones. Ju a young D. novce-hollandia:., with a length of 80 
mm. between the frontal suture and the occiput — that is, much larger 
than the largest of the skulls of D. minor — the sutures between 
the occipital, parietal, and frontal bones are widely open, and 
during maceration the bones separate from one another. Instead 
of there being any chance that the skulls are those of immature or 
not fully grown birds, it may be I'egarded as absolutely certain 
that only perfectly mature skulls would have any chance of 
surviving the movements of the shifting sand. 

Even more striking than the difference in size is that in the 
shape of the cranium of the island and the mainland form. The 
illustrations of the skulls seen in side-view in figures 5, 6 and 9, 
and the outline drawings representing the curvature of the upper 
surface of the cranium in two adult specimens of D. minor and two 
adult and one immature specimens of D. nnvcE-hollandice, show at 
a glance the great difference that exists in the cranial formation of 
the two forms. The outline drawings are life-size and in each 
case the horizontal line passes through the condyle posteriorly, 
and the suture of the frontal bone anteriorly.* The conti'ast 

* The drawings were made by means of the Dioptograph, designed by Dr. Rudolph 
Martin, for the opportunity of using which we are indebted to Professor R. J. A. Berrj".

between tlie doiue-sliaped skull of tlie island forin and the frontally 
flattened one of" the mainland iorni is sti'onjily marked. It will he 
noted also that the dome shape of the cranium is indicated to a 
certain extent in tlie immature mainland form The frontal 
region is certainly flattened, Init the proportionate height of the 
cranium above a basal line running from the condyle to the 
frontal suture is decidedly greater than in the mature specimens. 
Tliere is unfortunately no detailed description of the skull of IJ. 
peroni available, but it the dome shape of the cranium was any- 
thing like as well inarkcd in the Kangaroo Island species as it is 
in that of the King Island bird, it could not have failed to attract 
attention. This character alone is sufficient to distinguish the 
King island species from that of the mainland, and presumably 
also from that of Kangaroo Island. 

In the following table we give (1 ) certain length measurements 
of the skulls and (2) the proportionate height of the cranium to 
the length of a basal line drawn from the condyle to the frontal 
suture, taking this line as 100:—

6. Pec (oral Arch. 

(Plate 4. Figures 19 and 20.) 

Only one pectoral arch — that of the right side — has been 
found, and that has the clavicle missing, and about half of the 
scapular broken off". It is not perfect enough to found any com- 
parisons upon. 

7. Portions of three Sterna. 

(Plate 7.) 

It was found very difficult to secure remains of the sterna' 
which broke up into powder as soon as they were touched. 
The fragment figured i-epresents the greater part of it, but 
there is nothing apart from size to distinguish it clearly from 
the sternum of the mainland bird. The concavity on the 
inner or upper side is less accentuated, but then this is a 
feature in which the mainland form varies : one of our specimens 
being decidedly shallower and flatter than the one figured. The 
difference in size is, however, striking.

(Plate 4. Figures 10. 17, 18.) 

Oiilv two ribs were secured, and l)otli of these are broken, 
The larger one corresponds to the first rib tliat meets the sternum, 
and the smaller one to the third. Both belong to the right 
side. The tulierciilum of each is broken, and the capitnlnni is 
decidedly longer in jjroportiou tlian in the corresponding ril) of 
the niainlnnd form. 

10. Vertebral Bodies. 

The collection includes forty-three vertebra;, but, so great has 
been the action of the wind-driven sand, that not one of them is 
entire. A]iart from si/e, they do not apparently differ from those 
of the larger species. 

1 1. Toe Bone.<<. 
(Plate 4. Figures 13, 14, 15.) 
These are such solid parts of the skeleton that it might 
naturally be expected that thev would be well represented, but 
only two could l)e found. llach ^>t them is the proximal phalange 
of the large middle toe, and, apart from size, differs in no way 
from the same bone in the larger bird. 

In the table we give the measurements, and, on the supposition 
that the first phalange of the median toe has the same relation 
to the length of tiie whole toe in the island as in the mainland 
form, we have calculated the probable total length of the toe, 
taUing as a guide the length of tiie larger of the twn bones, 
which evidently iielony-ed to a mature l)ird : —

Genekai. Remarks on the Species of Duomjeuh Inhabiting 
THK Islands or Bas.^ Sikait. 

It is a matter of sjreat roiirot tliat in the earlv davs of 
Australian exploration so few specimens of the fauna of the islands 
of Biiss Strait were preserved. We know now. when it is too late 
to do more than gather together — and tiiat witii difficulty — such 
remains as we can secure of their skeletons, that these islands were 
the home of a species of Emu distinct from that of the mainland of 
Australia, and probably also from that of Tasmania. The early 
inhabitants of the islands were naturally not in the least interested 
in natural history, save so far as the animals that they found 
inhabiting the primeval scrub wei-e good to eat. Their only object 
was to capture as many seals and sea lions as possible, and 
whilst doing this they replenished their larder by exterminating as 
many birds and mammals useful for food as they could secure. 
P^ron records the fact that on King Island Cowper and his 
associates had actually trained their dogs to go out by themselves 
and hunt down Emus and Kangaroos.* When they had killed 
their prey the dogs returned to camp, and, "par signes non 
equivoque," announced their success, and then led the men to the 
places where their victmis lay dead. On Kangaroo Island, by 
means of one dog trained by the English sealers, and presented to 
the French naturalists, the latter were able to capture twenty-seven 
Kangaroos alive, and numberless others that were killed and 
eaten. Peron savs that Kangaroos are so easilv killed bv a trained 
dog that a few of these would not take many years to exterminate 
all the formei" on Kangaroo Island. 

Peron also relates that the English fishermen had actually 
domesticated the Wombats, ^vhich went out during the day into 
the foi'ests in search of food, and returned to their shelter huts at 
night.f We may be permitted to accept this statement with some 
reserve. P^ron and his associates were very hospitably treated by 
the English sealers when they were in a very uncomfortable plight, 
owing to their ships having to stand off suddenly from the coast ; 
indeed, if it had not lieen for Cowper and his friends the French 
naturalists would have had at least a very unpleasant time, so that 
naturally everything that they say about their rescuers and their 
surroundinps is not likely to suffer from any lack of friendly 
and appreciative description. 

If Cowper really domesticated the Woml:)at for the purpose of 
securing a ready food supply, then this is the first case on record 
of any such thing in regard to marsupials. How", in what must 
have been a relatively short space of time, he had trained them to

•ro out in the day in search of food and return to their huts at 
night is a mystery. This means not only tliat he liad ])ersua(ie(l 
the animals to aijandon their Ijurrowing habits, but, what is more 
remarkable still, he iiad changed a nocturnal into a diurnal animal. 
The domestication story must, we fear, be regarded as a mvth. It 
is true that Flinders remarks on the fact thatOn Clarke Island he 
saw Womliats feeiiing during the day time. (.)n the mainland the 
animal is also sometimes .seen duri'ig the day, l)ut it is e.ssentiallv 
nocturnal in its hal)its, and Sir Kverard Home states, in regard to 
one taken alive from King Island to [.rondnn, that it was quiet 
during the day and active at night. 

There is no doul)t that Enuis and Wombats were plentiful at 
the time of Peron's visit, and that I'eron actually saw them. 
There is a very curious discrepancy between two accounts that are 
published dealing with their size. Pcron makes the following 
.statement* :—" i.e puissant Casoar, liaut dc l(i a 22 decimetres 
(5 a 7 pieds)," and, in the margin opposite this, reference is made 
to plate (U"). ()n tlii' other hand, in the ])ublication by Messrs. 
Milne Edwards and Oustalet, to which we have already referred,f 
the following question put to, and the answer to it made by, 
Cowper, are given : — 

"G. Quelle est la hauteur la plus grande a laquelle il 
parvient ? 

A I'ile King, a pen pres 4 pieds I, plus petit qu'i Sydney." 

The plate referred to contains the figures of adult and voung 
birds, and bears the following legend :-" Nouvelle-IIollande — 
ile des kanguroos. Casoar de la N'"'- Hollande (Casuarius Novaj 
Hollandi;n-Lath.)" It will i)e noted that in the letterpress the 
name ile Decres is used, and on the plate the name ile des 
Kanguroos. It is evident that T^ron imagined that the island and 
the mainland forms of Rnm were the .same, and that he made very 
little efioit to ca])ture them on the islands— indeed, he says, 
speaking of Kangaroo Island, "Nous mimes peu de soin a. les 
cha.s.ser, nous ne pfimes nous en procurer que trois individus 
vivans.']: He makes no remarks whatever about the size of the 
Kangaroo island specimens.

savs f— " in addition to Decres or Kangaroo Island, also Flinders, 
King Island, and Tasmania had Emus living on them at the time 
of Ftjron's visit, and I believe, if authentic specimens from these 
localities were in existence, we should find that each of tliese 
islands had had a distinct species or race of Emus. Taking this 
for graiited, and also taking into account that it is slightly 
different from the type of D. peroni, 1 have come to the con- 
clusion that the Liverpool specimen is an inmiature, though full 
grown, individual from one of these other islands ; but it is not 
possible from this one rather poor specimen to se[)arate it from 
the Kangaroo Island species, especially as there is absolutely no 
indication of the origin of this specimen." The only other remains 
of the Kangaroo Island Enm are two bones, one a tibio-tarsus and 
the other a tarso-metatarsus, of which, through the courtesy of 
Professor E. C. Stirling, the Director of the South Australian 
Museum, we are able to give illustrations. 

Dr. Giglioli is of opinion that the Liverpool specimen is 
identical with the Paris and Florence specimens. Most unfortu- 
nately, there is no evidence whatever of where it came from or by 
whom it was collected. A few bones from King Island were also 
sent to Dr. Giglioli by the late Mr. Alex. Morton, and while 
pointing out the necessity of securing a larger series of bones from 
the ishuids Dr. Giglioli expressed the opinion that the King Island 
specimens belonged to D. peroni. 

With the comparatively large series of bones now available it 
is possible to form a tolerably correct idea of the average size of 
the King Island bird. Unfortunately, we have only the measure- 
ments of the bones of one specimen of D. peroni, but we have 
the advantage of knowing that this was full grown, as it lived for 
some time after its arrival in France either at the Jardin des 
Plantes or at the Chateau of Malmaison, and we may therefore 
regard it as probably an average sized specimen — more especially 
as there does not appear to be any great discrepancy in size 
amongst the Paris and the Florence specimens. 

* 111 his " Catalogue of the Fossil Organic Remains, Mammalia, and Birds contained in 
the Museum of the Royal College of Surgeons," London, 1845, p. 353, Owen makes the 
following statement hi regard to specimen No. 15(i3 :— " A corresponding section of the 
pelvis of a young Emeu (Drom(eii.-< aler), showing a smaller proportional expansion of the 
spinal canal for the enlargement of the chord whence the nerves of the legs originate, and 
the more marked difference in the form and ])ropoi-tions of the iliac plates, esiiecially 
behind the acetabulum." In his work on "The Extinct Wingless Birds of New Zealand " he 
also figures, in Plate xxxv. , fig. 7, a sternum to which he applies the name of Dromaius ater. 
No reference to this particular specimen nor any reference to the species is made in the letter- 
press. It seems clear that Owen is not using ater as a synonym for iiom -ho//aii'Ji'r, because 
the latter specific name is applied to specimens figured in Plates xxxi. and xxxvii.

SUB-FOSSIL REiMAINS FROM KING ISLAND. 



In the Following table we give the ineasiireineMts of tlie l)ones 
of six sj)eciiueiis of Drnmams nrwcB-hnlldndla;, of ;he large 
series of the King Island form, and the nieasnrenients of the one 
specimen of D. peroni. In the case of the King Island form we 
have given three series of measurements— the minimum, the 
maxinnim, and those between which lie the great majority of the 
measurements. Thus, for example, in the case of the fenmr the 
mininuun of mature bones is 14'> and the maximum 186, Init 
whilst onlv 2 specimens measure more than 180 and (? less than 
I. ')0 mm., ni) fewer than irl measure l)etween 150-180 nun., and 
of these 31) measure between 150-170 mm.

It will be seen that there is considerable variation, not only in 
the case of the King Island species, but also in that of the main- 
land si)ecies, and doul)tless a corres])()ii(ling amouiit of variation 
would be found to exist amongst the Kangaroo Island birds if oidy 
we were fortunate enough to ])o.s.sess as lai-ge a series of their 
bones as we do of those of the King Island Kmns. It is, for 
example, almost certain, or at least quite prol)able. that amongst 
the Emus of Kauiiaroo Island thei-e wei-e many adult bii'ds that 
exceeded the measurements given in the al)ove tal)Ie, and many 
that fell below them unless the three specimens .secured happened 
to belong to birds of either iiiaxiiiium or minimmn size. 

One verv striking fact in regard to the IJatitaj is that on insular 
areas we find a most remarkable develojmient of distinct .species, 
and that on continental areas there is a widespread distribution of 
a 'imited number of species. 

riiroughout the whole of the South American continent we 
iind only three species of Rhea. Africa has only three species of 
Struthio. 

[21 ] 



SUB-FOSSIL liKMAINS FliOM KING ISLAND 



Throughout the whole of Australia there is only one species of 
Emu*. Six living species of Apteryx are recognised on the islands 
of New Zealand, where tliere also exist the remains of at least 
twenty species of Dinornis and closely allied genera. In Australia 
there is only one species of Cassowary ; on the Papuan Islands to 
the north there are no fewer than ten species, and of these one 
species may be confined to one island, as in the case of the well 
known Ceram Cassowary, or several may occur on the same island 
as in the case of New Guinea. 

It is thus apparent that for some reason or another an 
insular environment is associated with considerable variation 
amongst Ratite birds. It would not therefore be a matter of 
surprise, judging by what has taken place in the case of the Ratite 
birds of New Guinea and the suiTouuding islands to the north of 
Australia, if King and Kangaroo Islands and Tasmania each 
possessed its own species of Emu. 

The measurements in the table given above indicate very 
clearlv the fact that the King and Kangaroo Island Emus were 
quite distinct from those of the mainland. Of this there can be 
no doubt whatever. There now remains the question of the 
identity or otherwise of the two former. Despite the fact that in 
the ease of the femur, tibio-tarsus and tarso-metatarsus our 
collection from King Island includes in each case one or two bones 
equal in length to the corresponding bones in the Paris specimen 
from Kangaroo Island, it is clear that these belong to exceptionally 
large specimens, and tliat the average size of these bones was con- 
siderably less than the maximum given in the table. The two 
bones from Kangai'oo Island also indicate the fact that the species 
of Emu inhaljiting the latter was of decidedly less robust build 
than that of King Island. Not only is this so, but the measure- 
ments of the skull and pelvis are quite sufficient to distinguish the 
two species. 

Both the King Island and the Kangaroo Island species were 
distinguished bv iheir dark colour from that of the mainland. 

We have now to deal with the question of the Tasmanian Emu. 
At the present time no Emu is extant in the island, but names such 
as Emu Bay and Kmu Plains evidently indicate the fact that when 
the island was first occupied by white men, and probably for many 
years afterwards, Emus did exist. Tlie only examples of the Tas- 
manian Emu of which we can find any record ai'e two skins of 
adult birds presented to the British Museum by Mr. Ronald Gunu, 
and recorded by Gray in his List of !!irds in the British Museum, 
iii., p. 54, 1844, and again by Salvadori in the British Museum 
Catalogue of Birds, xxvii., 1895. 

* D. irroratua of N.W. Auitralia is doubtfully distinct from D. novir.hollandia.

SUB-FOSSIL REMAINS FROM KING ISLAND. 



In 1804, the Ilt'V. U. KiKipwoKil wrote :i di.-irv of \n> visit to 
Tasmania wlicn H.M. ship Calcutta sailed from Port IMiillip to the 
Derwent River in lasmania.* On Wednesday, 7tli March, he lias 
the iolh)\ving recorii in his diary — " We see Kantiaroos, Emews, 
Pigeons, and Parrotts "; again, on .Monday, 2()th March, he says — 
"They cano;iit six voung Kmews, about tlie size of a turkey, and 
shot the oM mother ;" and, on 9th ()ctol)er, he records the capture 
by liis dogs of an "• Kmew (10 Ihs. \veight."t 

BisehofF,^ writing ill 1832, and ([uoting from " An Account of 
Van Diemen's Land," pul)lished hy Widovvson, in 1 829, says — 
" The birds that may lie called game are very numerous, with 
the exception of the Emu or Native Ostrich, they very much 
resemble the latter liird, and are very nearly as large." In the 
" Van Diemen's Land Anniversary and Hol)ait Town Almanac," 
for the year 18.11, the •' Emu or Cassowary Khea iSoviv-lIollan- 
diae," is included in " A glossary of the most common natural 
production of Van Diemen's Land," so that evidently the bird was 
well known at this early date. 

The Emu is known to have existed in large numbers in 
Tasmania up to at least the year 1840. Col. W. V. Legge,§ the 
distinguished ornithologist of Tasmania, states that during the 
'• forties "' the birds inhabited and bred regularly in a locality 
known as Kearney's Bogs, aljout 12 miles south of Avoca, 
amonu:st the ranjres of the east coast. He states that one of the 
shepherds '• u.sed not unfrecjuently to bring eggs to the house. 

Mr. D. Le Souef, in his notes on the extinct Tasnianian Emu,|| 
mentions that Mr. Ransom, of Killymooii, in the Fingal district, 
rememliers Captain Hepburn, ot Roy's Hill, Hnding an Emu's nest 
with eight or nine eggs. A little later these were hatched under 
a turkey hen. From the.se others were bred, and a pair of them 
were given to the late Baron von Steiglitz, of Kiilymoon, one of 
which survived until 1S7.S, when it was drowned while trying to 
cross a flooded river. With its death, the Tasnianian Emu. Mr. 
Ransom i)elieved, became extinct. 

Gould, in his ''Birds of Australia," pul)li.shed in 1848, states 
that Emus were then almost extirpated in Tasmania ; a few still 
ranging over the western part.

Mr. Geo. T. Lloyd* writing in 1H62, says, "The Emu ofTas- 
mauia, as I have before stated, is much smaller and darker in 
plumage than that of Australia ; hut, never numerous there, that 
noble bird is nr)w nearly extinct." 

One difficulty in I'egard to the safe identification of the true 
Tasmanian Kmu lies in the fact that at a comparatively early date 
specimens were introduced from the n)ainland. Mr. D. Le Souef 
states, on the authority of Mr. Stephens, that one or more were 
imported from Victoria by Mr. James Cox, of Clarendon, in the 
earlv " fifties," and others were introduced somewhat earlier. 

Further evidence of this is afforded by Mr. R. Gunn,f who, 
writina: in 1851, savs that he obtained two Emus from the Horti- 
cultural fi aniens in Hobart, and adds "they were originally from 
a Port Phillip stock, but brought up in Van Dieman's Land." 
He goes on to say, " a leg of a Tasmanian Emu is now in my 
possession, and so far as I can judge from it, as a very imperfect 
specimen, there ai*e differences in the an'angement and size of the 
scales, which may justify the separation of the Tasmanian Emu 
from that of New Holland." In a foot-note, Mr. J. Milligan adds 
that, " Captain Hepburn, of St. I'aul's Plains, possesses a breed of 
Tasmanian Emus, which he succeeded in rearing from eggs found 
many years since upon the high healthy land in his vicinity." 

Two eggs have been recorded as those of the Tasmanian Emn, 
one of which is in the collection of Mr. J. W. Mellor, of Adelaide, 
and the other in that of Mr. D. Le Souef, Director of the Zoological 
Gardens, Melbourne. Both are said to be considerably smaller 
than those from the mainland. The measurements given by Mr. 
Le Souef are 4*85 x 3"-40 inches and 4*80 x 3"50, as compared with 
.5 ".56 X ?>-6'3 inches of a tvpical egg of a mainland form. A bone 
found by Mr. H. H. Scott in a limestone quarry was sent to Mr. 
D. Le Souef, who identified it as the femur of an Emu smaller than 
those from the mainland, but too damaged to be of any value. 

Finallv, during: a recent visit to Eua,land, Mr. D. Le Souef 
examined the two skins of the Tasmanian Emu in the collection 
of the Bi'itish Museum, and arrived at the conclusion that they 
were distinct from those of the mainland, a conclusion in which he 
informs us he was confirmed by the Hon. W. Rothschild, 
Dr. Bowdler Sharp, and Mr. Hartert, who also examined them. 

On the evidence derived from the size of the earg Mr. Le Souef 
pro]iosed the name of Drnmceus diemensu for the I'asmanian bird 
that laid it, but exactly what this bird was it is now quite im- 
possible to say with absolute certainty. Presumablv, however, 
granting that the eggs are those of the true Tasmanian Emu, and

not somewhat small ones of introduced mainland birds, the two 
skins preserved in tiie British Museum belong to the same species 
of bird that laid the euirs referred to by Mr. Le Souef. ^'o 
adecpiate description of tliese skins has yet been jiublished, but in 
view of the facts that (1) we know of eggs found in Tasmania 
that are distinct from those of the mainland form, and (2) that 
there are two authentically recorded skins of Knuis from Tasmania 
that differ from those of the mainland bird, and differ also l)oth in 
size and colour from those of the Bass Strait Islands, it appears 
to be certain that Tasmania uas iuhal)ited by an Kmu distinct Ijoth 
from that of the Australian Continent and that of the Islands, and 
for this species when it is adequately described the name of D. 
ilit'ini'iisis may approijriately be retained.

In a separate paper we deal at length with the question 
of the different s])ecies of Phascolomys, popularly known as 
Wombats, that have been recorded from Australia, Tasmania, and 
the Islands of Bass Strait. It will suffice to say here that the 
earliest known Wombat was secured on Clarke Island, in Bass 
Strait, and taken alive to Sydney in 1797. There is no record of 
the name of its discoverer.* After lingering in captivity for six 
weeks it died; and in .Auuust of that year Hunter, then (Governor 
of New South Wales, sent the body together with a description of 
the animal to the Newcastle Philosophical Society, f In 1800 
ShawJ pnl)lished a brii-f description of this animal under the name 
of Didflitliijs tirsiii'i. Up to this year, and indeed until at the 
earliest 1802, the only Wombat known in England was the one 
sent home by Hunter. Bass found his sju'cimeM on Cape Barren 
Island ill 179'J, but no description of this was published nntil 
1802. 

/ There can be no donl)t whatever that all the early descriptions 
of Phascolomys were based upon specimens from tlie Islands of 
Bass Strait, and further still tluit without any adequate investiga- 
tion it was taken for granted that tin- Bass Strait Island species 
was idi'iitieal with the Tasmaiiian. •. )ur collection from the Bass 
Strait Islands includes eight skulks, thirty lower jaws, and two 
skins, and altera careful comi)arison of thi'se with fourteen skulls 
from Tasmania, and a large numl)er from Australia, we have 
come to the conclusion that the Bass Strait Island form is quite 
distinct from that, of Victoria and Tasmania, and that as already 

* It is generally stated that the first Wombat taken to Sydney was captured by Baas, but 
this is not ao.

described the two latter are also distinct from one another, though 
at the same time tliey are more closely allied than is the Hass 
Strait Island Wombat to either of them.* 

It is therefore necessary to distinguish specifically the two forais 
which up to the present time have been united under the name of 
of P/iaxcolomys ursiniis. As this was, without any douljt, a|)plied 
in the first instance to the particular form secured on Clarke 
Island, sent to England hy Hunter, and named Di(l<'li)hys ursimi 
l)V Shaw, we retain the specific name unlnus for the Bass Strait 
Island species, and redescribe the distinct Tasmanian species under 
the name of Ph. fasmamensis. 

It is an interesting fact that the first reliable drawings of a 
AVombat, those in the Atlas to Peron's work represent the King 
Island species, and further that one of the earliest descriptions of 
the anatomy of any species of the genus was based upon a specimen 
taken to London by the distinguished naturalist, R. Brown, who 
secured it on one of the Bass Strait Islands. f Sir Everard Home, 
when describing the anatomy of this sjiecimen, says that it lived 
in captivity with him for two years, and " It appeared to have 
arrived at its full growth, weighed about twenty pounds, and was 
about two feet two inches long." 

In addition to the sub-fossil specimens from King Island our 
original collection included a skull from Deal Island, indistinguish- 
able from the King Island skulls. For the purpose of procm-ing, 
if ]iossible, material from the Furneaux Group, of Avhich Clarke 
Island, the habitat of the first found Wombat, forms a part, one of 
us paid a visit to Flinders Island, the largest of the group, and 
made the interesting discovery that the small Wombat, though rare, 
is not yet actually extinct. Further reference to this is made in a 
separate article. Here it will suffice to say that the Deal, 
Flinders and King Island skulls are identical. Deal. Flinders, 
Clarke, and Cape Barren Islands, form parts of a chain of 
islands stretching across the eastern entrance to Bass Strait, 
whilst King Island lies far away on its western margin. It would 
be, at least, a most curious thing if the Deal, Flinders, and King 
Island wombats were identical, as they are, and at the same time 
distinct from those of Clarke and Cape Barren Islands. 

We have therefore decided to retain Shaw's specific name 
uraitn/s for the Wombat of the Bass Strait Islands. Though much 
has been written about it, and it is the oldest known species, 
it has for many years been confused with the quite distinct Tas- 
manian form, and it is doubtful if any well authenticated skin of it 
is in existence, except two recently secured on Flinders Island. 

* It is a somewhat remarkable fact that both the King Island Emu and Wombat are more 
distinct from tlie mainland and Tasmanian forms than the two latter are from one another.

Ihifortunately HuiitiM- in his letter to the Newcastle Philo- 
sophical Society, when sendins; to Kiigland the oriirinal specimen 
on which Shaw established the species, gave onlv a verv vagne 
description of it, nor does that specimen ajipear to have ever heen 
ade(|uately described.

account, whidi UMdoul)t('dly refers to this p^irticulnr species of 
Womliat,* then- is a curious error in regard to the dentition which 
must have arisen in consequence of a mistake in the transcription of 
notes. Taking Bass' account of the e.Kternal form and combining 
it with tlie results obtained from the investigation of the skulls 
from King. Deal, ?.nd Flinders Islands, and skins from the latter, 
the following may be taken as a fairly accurate description of this

&c." In speaking of Kangaroo Island he says,* " Nous y avons vu 
que trois cspuoes de mammifcrcs : I'une appartient au joli genres 
des Dasyures," and in connexion with tlie latter refers to a plate on 
which two Dasyures are drawn, the title of the plate being a.s 
follows : — " Nouvelle-Hollande : Nouvelle Galles dii Sud. Dasyure 
a longue queue ( Dasyurux Macrouriis^ Geof.)." 

It is evident that F6ron regarded the Kangaroo Island species 
as identical with the larger mainland form now known as Ddsifurua 
tnaculaf.iis^ but he says notliing with regard to the two King Island 
species, and does not appear to have collected specimens. 

At the ])r('sent two species of Dasyurus are known from 
Victoria and Tasmania, a somewhat larger form, D. maculalns, and 
a somewhat smaller one, D. vivp.rriiiu.s. Both of these are found 
in Victoria and Tasmania, the first-named species being more 
abundant in the island than on the mainland. During the visit ot 
the Field Naturalists' Club in 1887, D. maculntus was reported as 
existing on King Island, but not D. virerrinns. 

Our collection of bones includes tiie remnants of twenty-five 
crania, and sixty lower jaws, one of which came from Deal Island. 
No trace of any other bone could he found. 

The crania and jaws are clearly divisible into two sets, a larger 
and a smaller, indicating the existence of two species as recorded 
by P^rou, who, unfortunately, gave no indication of their relative 
size. The question arises as to the relationship of these two 
species to those now existing in Australia and Tasmania. In our 
collection, twenty-one of the crania belong to the larger form, and 
four only to the smaller. Of the lower jaws, thirty-seven appear 
to belong to the larger, and twenty-nine to the smaller. The 
difference in size is not due to immaturity, the dentition of both 
series being the permanent one. 

In order to try and decide the relationship of the fossil forms, 
we have made a considerable number of measurements of skulls 
and lower jaws of recent specimens, the results of which are given 
in the following tables.

Tlie measurc'iuents in the first pliice show unmistakably that 
D. vici'.rrinas is not represented amongst tlie remains. 

They equally clearly indicate the existence of a species decidedly 
larger than the existing D. maruliilu.s, and at the same time prove 
the existence of animals of a size equal to that of large examjiles of 
D. maculatus. The question then arises as to whether the smaller 
King Island specimens are to he regarded as females of the larger 
form or as re[)resentatives of another species, that is D. maculatus. 
"We incline to the latter opinion which, moreover, is in accordance 
with the definite statement made by Per(jn that two species existed 
on the island. 

A reference to Plate 8, Figs. 2 and 3, representing a larger 
and smaller specimen will serve to show how distinct the forms are, 
and though, of course, the smaller amongst the larger forms tend to 
merge into the larger amongst the smaller, yet an examination of 
the collection as a whole unmistakal)ly gives the impression that it 
contains the remains of two distinct foTuis. 

The evidence from the teeth is as decisive as that from the 
basal length of the skull, \\\ no example of D. maculatics does the 
length of the upper first three molar teeth exceed i9"5 mm.; in 
the large island specimens it is consistently 20 mm. or more, and 
the same difference is seen in the leno-th of the lower molar series 
and of both the upper and lower pre-molar. 

But beyond these measurements there is fortunately one 
structure in the skull which Ijoth serves still further to mark the 
larger form out as a distinct si)ecies and at the same time bears 
evidence in favour of the fact that the smaller island form is 
D. maculatifs. Two of the larger and two of the smaller skulls 
fortunately have the mastoid bulbe sufficiently intact to show 
clearly what was its size. In D. viverrinus this is very largely 
inflated, the breadth of the bulla being at least three-quarters the 
length ; in D. maculatus the expansion of the Ijulla is not so great, 
the breadth beino- slio;htlv more than half the lenath. When we 
examine the King Island specimens (Figs. A, B, C,) we find that in

the large ones the bulla is decidedly more elongate and much less 
swollen, whilst in the smaller ones it is similar to that of 
D. maculatus. In a large island form witli a basal length of 

[ 32 ] 



SUB-FOSSIL UF.MAINS FROM KING ISLAND. 



117 mm. the width of the hulla is 6 mm. ; in a small island form 
with a basal length of BTo nmi., the width is C mm., and in a 
D. inaculatus, with a basal length of 91 mm., the width is 6-5 mm. 

Taking evervthing into account we are of opinion — tirst, that 
the Dasyurus remains include those of two sjjccies ; secondly, that 
tlie larger of these two is distinct from any yet described ; and, 
thirdly, that the smaller form is identical with /). muctdatua. 

It is of conrse possible that the larger species may still exist in 
some of the wilder ami more inaccessible parts of the island, l)Ut it 
is much to l)e feared that, like the small Wombat and the Kmu, it 
is now (juite extinct, and will only be known from its sub-fossil 
remains. 

We describe it as follows, and associate with it the name of Mr. 
J. McKie Bowling, to whose assistance in securing these remains 
from King Island we are nmch indebted.

THi: FXCTTNO SPEriES OF THE GENUS 
PH.\SrOLO)[YS. 

By Baldwin Spencer, C.M.O.. M.A.. F.R.S., Hon. Director of the 
National \[>isrum, and J. A. Kershaw, F.E.S., Curator of the 
Zoological Collections. 

{Plates 9, 10, 11.) 



In this papor we propose to deal principally with the question 
of the relation to one another of the species of Phascolomys that have 
been described as inhabiting; Victoria, Tasmania, and the Islands of 
Bass Strait. At the present time, three existinji species of the genus 
are recognised in Australia, viz. : — Ph. ursinus of Tasmania and the 
Islands of Bass Strait, Ph. mitchelli of Victoria, New South Wales, 
and South Australia, and Ph. latifrons of South Australia. The 
latter with its almost silW fur, its hairy nose, and strongly marked 
post -orbital processes, is a very clearly defined species. 

Until quite recently it was supposed that the Bass Island forms 
were extinct, and Ph. ursinus has been known only by specimens 
from Tasmania. Mr. Oldfield Thomas,* describing the latter animal, 
says — ■" This species, the oldest known of the group, presents a 
remarkable exception to the usual rule of size in Tasmanian animals, 
these being generally larger instead of smaller than their continental 
allies. The species seems to be well distinguished from Ph. mitchelli 
bv this character of size, but otherwise there appears to be no 
difference of importance between the two," 

The investigation of a collection of sub-fossil bones from King 
Island has caused us to inquire into the history- of this species, an 
outline of which we propose to give. 

During the year 1797, a ship called the Sydney Cove ran on shore 
in Ba.ss Strait, between Preservation and Rum Islands, which 
form part of the Fumeaux group, and lie off the south-west coast 
of Flinders Island. Hunter, then Governor of New South Wales, 
sent a boat down from Sydney to rescue the ship-wrecked crew, and 
this party brought back with it the first found wombatf. It only 
lived six weeks in captivity, and in August, 1798, Hunter sent its 
body to England " for the inspection of the learned members of the

t It is, however, flifliriilt to say positively whether this first womhnt was brought back to 
Sydney by the tirst exptvlition sent to rescue the crew "f the Si/dnfii (.'orr or by Flinders himself 
when he went down on a second expedition to the scene of the wreck in the schooner Franr.it, 
leaving Port Jackson on Febniary I, 1798, and returning on March 0th.

EXISTING SPECIES OF THE GENUS PHASCOLOMY8. 

Early in 1798, Bass had made his celebrated expedition in a 
whale boat, penetrating the strait that now bears his name, and in 
October of the same year, accompanied by Flinders, he again set 
out, this time in a small sloop called the Norfolk. During this expe- 
dition he found and brought back a wombat from Cape Barren 
Island.* It is commonly stated that Bass found the first wombat, 
but this is not so. As a matter of fact. Hunter sent his specimen to 
Newcastle in August, 1798, and Bass only returned to Sydney with 
his in January, 1799. It is also evident that Flinders knew of the 
existence of the animal when, late in 1798, he accompanied the 
schooner Francis on its second visit to the wreck of the Sydney Cove. 
He refers several times to it, calling it by its native name, that is, 
the name applied to the mainland form by the aborigines of Kew 
South Wales. Thus, for example, he saysf — " The stations whence 
angles were taken for a survey of the channel and surrounding lands, 
were — first. Point Womat, a rocky projection of Cape Barren 
Island ; " and, again, speaking generally of the Furneaux Islands,! 
he says — " No other quadrupeds than the kangaroo, womat, and 
duck-billed aculeated ant-eater were found upon the islands ; " 
and, lastly, he says§ — " Clarke's Island afforded the first specimen 
of the new animal called Womat, but I found it more numerous upon 
that of Cape Barren ; Preservation and the Passage Isles do not 
possess it. The little bear-like quadruped is known in New South 
Wales, and called by the natives womat, wombat, or womback 

it burrows like a badger, and on the continent 

does not quit its retreat tiU dark ; but it feeds at all times on the 
uninhabited islands, and was commonly seen foraging amongst the 
sea refuse on the shore, though the coarse grass seemed to be its 
usual nourishment." 

In 1800, Bewick issued the fourth edition of his History of 
Quadrupeds, and in this|| appears in fuU the letter dated August 5th, 
1798, addressed by Hunter to the Philosophical Society of Newcastle, 
in which he states the position of the island on which the animal was 
found and describes it.^ Amongst other things he says — " It is 
about the size of a badger, a species of which we supposed it to be 
from its dexterity in burrowing in the earth, by means of its fore 
paws ; but on watching its general motions, it appeared to have 

much of the habits and manners of a bear This animal 

has lately been discovered to be an inhabitant of the interior of the 
country also The natives caU it wombach." 

This is undoubtedly the earliest notice published of any species 
of Phascolomys, and was indeed the only description of the animal

sent to Europe up to the year 1800. Bewick gives no scientific 
name to the animal, but above Hunter's letter appears a quaint 
figure of the animal, which is entitled " The Wombach." There 
can be no doubt that this account formed the source of infonnation 
upon which Shaw founded his very brief description of Didelphys 
urshia. 

His description reads as follows : — * 

" Ursine opossum." 

" Didelphis ui-sina. D. flavescens lahio superiore bifido. 
Yellowish 0. with bifid upper lip. 

The largest of all the opossums : size of a badger: colour, pale 
yellow : fni-, longish and sub-erect : nose strongly divided by a 
furrow. 

Xative of New Holland : a species very lately discovered and 
not yet fully or satisfactorily known or described." 

The letter from Hunter, and Shaw's brief description, seem to 
have attracted no attention, but when, in 1802, Collinsf published 
his Account of the English Colony in New South Wales he 
included in it Bass' description of the specimen that was captured 
on Cape Barren Island. It is, at least, a curious fact that in this 
lengthy account no reference whatever is made to Hunter's specimen ; 
on the contrar}- Collins speaks of Bass' finding on Cape Barren 
Island " a new quadraped which was also a grass eater." He goes 
on to say — " This animal, being a stranger, appears to merit a par- 
ticular description. The wom-bat (or, as it is called by the natives 
of Port Jackson, the Wombacl-) is a squat, thick, short-legged, and 
rather inactive quadmped, with great appearance of stumpy strength, 
and somewhat bigger than a large turn-spit dog." It is difficult to 
account for this, because certainly Flinders, and without doubt 
Bass also, were well aware of the previous capture of wombats on 
Clarke Island ; it is indeed, as pointed out previously, ((uite possible 
that the first specimen was actually captured by Flinders himself. 

In describing the animal from Bass' notes, Collins says that it 
head measures 7 inches in length, the body 23 |";, inches, and that its 
weight was from 25 to 30 lbs. The animal was a female, and 
amongst wombats this sex is heavier than the male. Collins de- 
scribes how Bass chased one " and with his hands under the belly 
suddenly lifted him off the ground and laid him upon his back, 
along his arm, like a child He carried the beast up- 
wards of a mile, and often shifted him from arm to arm, sometimes 
laying him upon his shoulder, all of which he took in good part, 
until being obliged to secure his legs while he went into the bmsh 
to cut a specimen of new wood, the creature's anger arose with the

pinchinji of the twine ; he whizzed with all his might, kicker], and 
scratchod most furiously, and snapped off a piece from the elbow 
of Mr. Bass' coat." To those who are acquainted with the animals 
in their living state, the idea of Bass carrying for a mile, apparently 
with ease, a f\ill-grown female specimen of Phoftcolomys tirsinus 
(as at present recognised) which does not usually weigh much less 
than 50 lbs., is suggestive of some mistake having been made in this 
account. It would take a verv strong man to hold and carry a full- 
grown Tasmanian wombat if it behaved as Mr. Bass' specimen did. 
i.e., " whizzed with all his might, lacked, and scratched most furiously." 
By some curious error, either Bass or Collins confused the account of 
the wombat with that of some other animal in regard to the teeth. 
Towards the close of his description, which is otherwise quite correct, 
Collins wrote — " The opening of its mouth is small : it contains five 
long grass-cutting teeth in the front of each jaw, like those of the 
kangaroo : within them is a vacancy of an inch or more ; there 
appear two small canine teeth of equal height with, and so much 
similar to, eight molars, situated behind, as scarcely to be distin- 
guishable from them. The whole mxmber in both jaws amounts to 
twenty-four." The description is accompanied by a drawing of the 
animal, which is quaint but unmistakable, and bears a strong re- 
semblance to, though it is much larger than, Bewick's figure. The 
style of drawing and curious pose of the animal, the position of the 
front and hind legs and of the head — aU of these are identical in 
the two illustrations. We think there is very little doubt that they 
were drawn by the same hand. There is no evidence that any white 
man, up to that time, had ever seen the mainland wombat — all that 
they knew was that a similar creature did exist in New South Wales. 

In neither Bewick's nor CoUins' account was any scientific name 
applied to the animal. 

During the years 1800-1804, the celebrated French expedition 
under the command of Baudin was engaged in exploration around 
the coast of Australia and Tasmania. 

One of Baudin's ships, the NaturaUste, sailed for Europe in 1802, 
parting from the other two ships, the Geographe and Casuarina, at King 
Island. The NaturaUste carried to Europe specimens of the wombat, 
which presumably came from King Island, though this is not defi- 
nitely stated. In 1803, E. Geoffroy published a preliminary de- 
scription* of the animal brought to Europe by the NaturaUste, and 
proposed the generic name of Phascolomys. Evidently he was quite 
unacquainted with the works of Bewick and Shaw, but had seen 
CoUins' account, because he says that the animal described by Bass, 
" a le porte de nos nouveaux animaux : mais il en est bien certainement 
different, si les observations qui out ete pubhees sur leurs dents sont 
exactes." He adds, " Us out ete trouves a la cote occidentale de la

Noiivelle-Hollande." In those early davs, ideas with regard to 
Austmlian ceorrinphv were naturally mther vajnie. CJeoffroy says 
that the wombats were 17 inches long, but as they were young, 
there was reason to think that if the two that remained coidd be 
kept alive, thov would reach the size of a badger. He also adds 
that they appear to be endowed with very little energy, they prefer 
to sleep during the day, and, like bun-owing animals, search for their 
food at night time. 

In the same year, Desmarest mentioned the animal under the 
name of Wombattns fossor* It is evident that he had not seen, or 
at least, carefully investigated a specimen. Sevastianof, writing 
in February', 1807. describes the skins of two quadnipeds sent to 
the Museum in St. Petersburg by a correspondent of the Academy, 
living in London, named Waxel.f One of these was a specimen of 
Dasijurus maculafus. the other was a species of wombat " decouvert " 
says Sevastianof, " par les navigateurs anglois Bass et Flinders dans 
la nouvelle Galle du Sud." He goes on to quote Desmarest's de- 
scription of WombatKS fossor, and adds finally, " Desmarest a range ce 
quadrupede dans le meme ordre et sous-ordre, que Dasyure tachete. 
II est carnassier par ce qu'il a six incisives et deux canines a chaque 
machoire." Sevastianof had only a skin, of which he gives a very 
fair figure, and it is evident that Desmarest's name was applied in 
the first instance to the specimen secured by Bass. 

In 1807 there appeared also the fii-st edition of the first volume 
of the letterpress of Peron's Voyage ; the atlas to this appeared 
in 1808. J In the first edition, there appears a plate. § drawn by 
Lesueur, with the following legend — " Nouvelle-HoUande : ile King. 
Le wombat (Phascolomys wombat)." Good drawings are given of a 
light and dark variety of the animal, together with four young ones. 
• The letterpress describes how four naturalists, including Peron and 
Lesueur, were left stranded on King Island, when a violent gale forced 
the exploring vessels to stand out to sea. The naturalists were hospi- 
tably entertained by some English sealers, the leader of whom was 
a man named Cowper, from whom they gathered many particulars 
concerning especially the emu that then existed in large nunibei-s 
on the island. Unfortunately, beyond describing how Cowper and 
his associates had domesticated the wombats, which went out during 
the day-time to feed in the scnib and returned at night-time to the 
huts, and describing also the value of the animal as an article of food,

thev tell us very little about it. In one part Peron says that lat^r 
on he intends to deal in greater detail with the animals to which he 
makes brief reference, but unfortunately, he died before his work 
was completed, and in regard to the Bass Island wombat, the only 
really valuable record in Peron's work is this plate. Possiblv the 
figures were drawn from life by Lesueur during his enforced stay on 
the Island. The legend attached to the plate proves clearly that 
in 1808, the name Phascolomys ivombat was applied bv Lesueur 
and Petit to the King Island species. 

In the year 1802, also, Charles Grimes,* Acting Surveyor-General 
of New South Wales, made a voyage of discovery in the Cumberland 
from Sydney to King Island, and in a journal kept by Flemming, 
it is stated that the party from his ship met the members of the 
Baudin expedition, and that " the captain (Bobbins) hoisted His 
Majesty's colours behind the French tents." The journal also says 
that on Thursday, 30th December, 1802, they " caught four emus, 
three badgers, three porcupines, and a kangaroo " — ^badger being 
the popular name then applied to the wombat. 

While Baudin with his three boats, the Geographe, Naturaliste, and 
Casuarina, was exploring the southern coasts of Australia, he met 
Fhnders at Encounter Bay. Flinders, in the Investigator, had previously 
to this visited King Island and there found the wombatsf which were 
well-known to him after his experiences amongst the islands of the 
Furneaux Group. He says — " On stepping out of the boat, I shot 
one of those bear-like little quadrupeds, called womat, and another 
was afterwards killed." Flinders was detained by the French at 
Mauritius, but material collected by Brown, who accompanied him 
as a naturalist, evidently reached Europe safely, for in 1808, Everard 
Home read a paper before the Royal Society in which he embodied 
an anatomical account of it written by Brodie. J Home says that the 
wombat was a male, that it " was brought from the islands in Basse's 
Straits by Mr. Brown, the naturalist attached to Captain Flinders' 
voyage of discovery. It lived in a domesticated state for two years. 

It was quiet during the day, but constantly in motion 

during the night It appeared to have arrived at its 

full growth, weighed about 20 lbs., and was about 2 feet 2 inches 
long." 

In 1811, Illiger enumerated two forms under the names respec- 
tively of Phascolomys fusca, Geoff., and Amblotis fossor, the latter 
genus being founded because Illiger, on account of the wrong de- 
scription of the teeth given by Collins, naturally imagined that the 
animal originally described under the name Vombatiis could not be 
the same as that to which the generic title Phascolomys was afterwards 
given. The latter animal he distinguished as Phascolomys fusca.^

EXISTING SPECIES OF THE GENUS PHASCOLOMYS. 

We now come to a description by Leach, published in 1815,* in 
his Zoological Miscellany. In the matter of brevity and inadequate- 
ness, it much resembles the original one of Shaw, but it is accom- 
panied by a better fiijure. The description is as follows : — " Phasco- 
lomis Vombatus. P. pallide fidvescentc-brunneus : naso obscuriore ; 
unguibus elongatis. Wombach. Bewick, Gen. Hist, of Quadrup., 
Ed. 4, p. 522. Habitat in Aiistralasia." Then he goes on, "Wom- 
bat phascoloinis. Pale fulvescent-brown : nose darker: claws 
elongated : inhabits New Holland. 

For an account of the anatomical stnicturo of the Wombat Phas- 
colomis, see Philosophical Transactions for 1808. It is named ^^'olu- 
bat, or Wombach, by the natives of New South Wales, who kill it for 
food, its flesh being considered verv' delicate. The usual length of 
this animal is about 2 feet, exclusive of the tail." Reading this, 
one would feel doubtful as to whether the writerhadeverseen the ani- 
mal, but on referring to Gray's List of the Speci7nens of Mammalm in 
the collection of the British Museum, p. 95, published in 1843, the follow- 
ing entr\' occurs : — " b. Young : discoloured, having been in spirits. 
(The one figured in Leach. Z. Misc. t. 69)." Only five specimens of 
wombat are recorded, the one mentioned above, two from New Hol- 
land, one from Mr. Gould's collection, and a young one from Van 
Diemen's Land. No locaUty is given for Leach's specimen, nor does 
he help us in his own description, beyond saying that its habitat is 
New Holland, and that Home described the anatomy of the species. 
Home's specimens we know came from King Island. In Thomas' 
catalogue (1888), apparently the same specimen is described as a 
young skin, and the locality of Tasmania is ascribed to it. It would 
be interesting to know the definite authority for this locality, as, up 
to the time when Leach published, that is, twenty-eight years before 
Gray's catalogue was issued, there is no record of any tnie Tasmanian 
specimen having been sent to Europe. 

It is to be presumed that, as neither Gray nor Leach in 1815, nor 
Gray in 1843, give any definite locality for this particular specimen, 
none was known when those writers published, more especially since 
Gray carefrdly gives the locality of eveiy other specimen. So far as 
the name is concerned, it does not matter, inasmuch as that of Phas- 
colomys Wombat had been applied to the King Island species eight 
years before Leach published his description. There can, however, 
be no reasonable doubt that the specimen described by Leach came 
from the Bass Strait Islands. 

Cuvier, writing in 1817,t describes and figures the animal and 
its skull. He says that only one species is known, which is of the 
size of a badger and lives on King IslandJ and that this is identical

with Shaw's Didplphis ursina. Tho fijnirfi that ho frivps is one of a 
brown variety, and was drawn from a stuffed specimen in the Paris 
Museum — presumably one of those captured durinj; Baudin's expe- 
dition. Lesson and Gamot, describing the zoolorrical results of 
Duperrv^'s voyage in 1826, say* — " Nous ne trouvAmes qu'une seule 
peau de wombat on phascolome a Sydney (didelphis ursina, Shaw ; 
phascolomys wombat. Per. et Les.) animal qu'on n'observe que surla 
cote sud et dans les petites lies du dotroit de Bass." 

In 1831, Owen, when describing the specimens of wombat in 
the collections of the Eoyal College of Surgeons,! stated definitely 
that the distribution of Phascolomys Wombat was " King Island and 
near Port Jackson," and makes no reference at all to Tasmania. 

It is, we think, quite certain from the above records that before 
the year 1831 no wombat had been sent to Europe from Tasmania.! 
With the solitary exception of the skin which Lesson and Gamot 
mention as found in Sydney in 1826, there is no record of a specimen 
actually secured on the mainland, and even in this instance there is 
no proof that the skin was that of a mainland animal. It is quite 
likely that it had been brought to Sydney from one of the Islands in 
Bass Strait. It is difficult to believe that no specimens were sent 
from New South Wales, but, if any were, no record of them appears 
to have been published, and, apparently, it was taken for granted that 
the wombats of King, Clarke, Cape Barren, and other islands in Bass 
Strait were identical with those of New South Wales ; indeed. Owen's 
statement in regard to the distribution of Phascolomys Wombat, 
quoted above, makes this quite clear. 

In 1838, Ronald Gunn,§ one of the earhest naturalists in 
Tasmania, contributed to the Annals of Natural History a 
paper entitled " Notices of some Mammalia and Fish from 
Van Diemen's Land," and to this, Gray added some notes in 
which, referring to the wombat, he says — "I have seen Bass' 
specimen, which is now in the museum of the Natural History 
Society of Newcastle-on-Tyne ; it is the same as the one we now 
usually receive from Van Diemen's Land, only discoloured by having 
been kept in spirit." It is evident that this particular specimen 
must have been the one sent to England by Hunter, and not by Bass. 

In 1838, Owen described a mutilated sub-fossil cranium found 
by Mitchell in the Wellington Valley in New South Wales, under the 
name of Phascolotnys mitchelli — this being the fii-st occasion on which 
a distinct name was given to a mainland form.] | In his description,

J In 1831, a large wombat reached England, lint whether it came ftom Tasmania or Aus- 
tralia is not known. This particnlar animal lived in the Zoological Society's gardens for five 
years ; in 1830 it died, and its anatomy was described by Owen.

Owen remarks that it is a little larger than the largest wombat's 
cranium in the Hunterian collection. This is not sui-prising, since 
the latter specimens were all presented by Home, and came from 
King Island. 

In 1836, Owen described the anatomy of a specimen* under the 
name of Phascolomys wombat, Peron, at the same time making the 
following remarks : — " The individual lately dissected at the museum 
of the Zoological Society had lived at the gardens upwards of five 
years. The one dissected by Sir Everard Home in 1808 was brought 
from one of the islands in Bass Strait, and lived as a domestic pet in 
the house of Mr. Clift for two yeare. This animal measured 2 feet 
2 inches in length, and weighed about 20 lbs. It was a male. The 
society's specimen was a female and weighed, when in full health, 
in October, 1833, 59 J^ lbs." Owen does not say where his specimen 
came from. The fii-st definite notice of the existence of a wombat in 
Tasmania that we can find is in the paper published by Gunn in 
1838, to which we have already referred. The author, Mr. Ronald 
Gunn, was well known as a naturalist in the early days of Tasmania.f 
In this he describes the animal under the generic title Phascolomys, 
but gives no specific name. He states that one large specimen that 
he secured measured 36 inches from snout to tail, and 34 inches 
in circumference. 

Waterhouse, J writing in 1841, accepts the name Phascolomys wom- 
bat, and says that " the wombat is found in New South Wales, South 
Australia, and Van Diemen's Laud, as well as in some of the Islands 
in Bass's Straits." Gunn's collection was presented to the British 
Museum, and possibly it included the young specimen mentioned 
by Gray m his catalogue,§ with the locality given as Van Diemen's 
Land. So far as we can ascertain this was the first occasion on which 
a specific name was applied to a definite example of a Tasmaniau 
wombat, Gray regarding it as an example of Phascolomys ursinus. 

In 1845, Owen in his article on Marsupialia iir Todd's Cyclo- 
pedia,\\ deals with many points in the anatomy of the wombat and 
figures a complete skeleton, the name Phascolomys jusca appearing 
under the figure. This is the only mention that he makes of this 
specific name. In the same year he exhibited at a meeting of the 
Zoological Society^! " the skull of a wombat {Phascolomys vombatus, 
Auct.) from Van Diemau's Land, and the skuU of a wombat trans- 
mitted by Governor Grey from Continental (South) Australia." He 
pointed out their dillerences and named the new continental form 
P. lalifrcms. In 1847** Gray drew attention to certain differences

in the teeth of three skulls, two from Van Diemen's Land, and one from 
New South Wales, and suggested that there might be more than one 
species confounded under the name Phascolomys vomhatus. Matters 
remained in this state until, in 1853, Owen described two skulls in the 
collection of the Koyai College of Surgeons* as distinct from Phas- 
colomys vomhatus. For these he proposed the name P. flatyrhinus, 
that is, under different names as regards two of them, Owen at that 
time recognised the three recent species that are now accepted, viz., 
Phas. vomhatus ( — Phas. ursinus), Phas. flatyrhinus ( = Phas. mitcheUi), 
and Phas. latifrons. Apparently, however, he regarded the first of 
these as distributed on the mainland as well as in Tasmania and the is- 
lands. Some confusion arose in regard to the South Australian species, 
named originally by Owen on the strength of a skull only. AYhen 
the skin of the hairy-nosed wombat of South Australia was first seen 
it was not identified as belonging to the same animal to which Owen 
gave the name P. latifrons. Gray accordingly founded a new genus 
and species for it,t Lasicrhinus m'coyi ; Gould called it Phas- 
colomys lasiorhinus% and Krefft described a dark variety under 
the name of P. niger.§ Of the distinctness of P. latifrons there is no 
doubt. There remains the question of the Eastern mainland species, 
that of Tasmania, and that of the islands. 

In 1865, Murie published a paper deahng in detail with the 
various species. || He came to the conclusion that P. mitchelli and P. 
flatyrhinus were identical, but retained the latter name for the recent 
species, and also, Hke Owen, recognised two other species — Phas- 
colomys womhat and Phascolomys latifrons. These residts he con- 
firmed in 1867, but curiously says nothing definite with regard to 
the geographical distribution of the species. McCoy, writing 
of Phascolomys womhat in 1868,^ said, " This is now known to be 
confined to Tasmania and other islands south of the Australian con- 
tinent, and as I have demonstrated from the specimens on the table, 
it is specifically distinguishable with ease and certainty by the charac- 
ters of the skull and skin, pointed out by Dr. Murie and others, from 
the wombats of the mainland, which were at one time supposed to 
be referable to it." Krefft,** in 1871, says again that Phascolomys 
wombat " is peculiar to Tasmania and the islands of Bass Strait. 
The New South Wales wombat {Phascolomys flatyrhinus) is found 
on the east and south coast, extending even as far as Victoria, where 
also a brown variety occurs. This eastern wombat differs little 
from the Tasmanian one, except that it is larger and grows to over 
SO lbs. in weight."

EXISTIXG SPECIES OF THE GENUS PHASCOLOMYS. 



In 1888, Thomas published his well-known Catalogne. and in 
this used the names that have been applied ever since to the existing 
species, viz., Ph. uraimix for the Tasnianian and Bass Strait Island 
species; Ph. mitcheUi for the common mainland form with naked 
muzzle ; Ph. latifrons for the hairy-nosed, South Australian species. 

The main points in regard to the history of the various species of 
wombat up to the present time may be briefly summarized as 
follows : — 

(1) The discover}' of a wombat on Clarke Island in Bass 

Strait, to which the specific name of ursina was first 
given. (1797). 

(2) The discoverv of a wombat on King Island. (1S02). 

(3) The discover)' of a wombat on the mainland of AustraUa. 

first in New South Wales, later in Victoria, supposed 
to be identical with the Bass Strait Island species. 
(Exact date uncertain). 

(4) The discovery of a wombat in Tasmania, supposed to be 

identical with the island and mainland species. (Exact 
date uncertain.) 

(5) The discovery of a fossil species (Ph. mitchdli) on the 

mainland.' (1838.) 

(6) The discoveiy of P. latijrons in South Australia. (1845.) 

(7) The detennination of P. flatyrhinus on the mainland, as 

distinct from P. urswus of Tasmania and the islands 
of Bass Strait. (1865.) 

(8) The discover)^ of the specific identity of P. mitchelli, the 

fossil form, and P. flatyrhinus, involving the retention 
of the former name for the New South Wales and Vic- 
torian species. (1865.) 

(9) The discovery of sub-fossil remains of the King Island 

wombat.*' (1903.) 

(10) The discovery on Flindci's Island by Mr. .). A. Kci-shaw 

of living specimens of wombats identical with the sub- 
fossil remains from King Island. (1908.) 

A comparison of the skulls from King, Deal, and Flindci's Islands 
shows that the same species of wombat was distributed over all 
three, and as Clarke and Cape Barren Islands form part of the Fur- 
neaux group, separated from Flinders Island and from one another 
by only shallow, narrow passages, we may safely conclude that the 
wombat which once existed on these two islands was identical with 
that on Flinders. 

* Wc have dealt at length with this in a previous paper. Cf. " A Collection of Sub-foaail 
Bird and ^[arsupial remains from King Island, Boss Strait. ' Memoira of Nat. .Vtw., Meibourne. 
\o. 3, p. 28.

EXISTING SPKCIES OF THE OENIS I'llASCOLOMyH. 



It is many years ago since the King Island wombat was exter- 
minated. When the island was visited by a party of the Victorian 
Field Naturalists Club in 1887, no trace of it was discovered nor, 
during the process of clearing the land that has been vigorously 
carried on during recent years, has any record of a living wombat 
been made. 

Flinders Island afforded the only prospect of securing a living 
specimen of the Bass Strait species, and in the hope of finding that 
the animal had not been completely exterminated there one of us 
(J. A. Kershaw) took advantage of a trip organized by the Aus- 
tralasian Ornithologists' Union to visit the island in November, 1908. 
A considerable part of the north, north-east, and north-west coast 
line was examined, and abundant evidence was obtained to prove 
that the animal, though very rare and difficult to obtain, was not 
extinct. In the deserted hut of a half-caste native at KilUecrankie 
two skins were foimd. On the extreme north end of the island an 
incomplete skeleton, including a skull with the skin still attached to 
it, was secured, and part of another skin on the north-east coast. 
On the island there are, in addition to a few settlers, a number of 
half-castes, or rather the much-mixed offspring of whites, Austra- 
lian, and Tasmanian aborigines. The existence of the wombat is 
well-known to them, but it is by no means easy to secure. During 
the three days spent in searching no living animal was seen, and all 
that could be done was to make arrangements to have one sent to 
Melbourne when captured. On Cape Barren Island, where most of 
the half-castes live on the native reserve, the animal was found to 
be quite extinct, though well-known under the name of " badger," 
the common term " wombat " not being known there. 

Though not successful in obtaining a living specimen, Mr. Ker- 
shaw's visit was the means of proving that the animal is still extant, 
and in addition to the sub-fossil remains from King Island we now 
possess also recent remains, including skins from Flinders Island. 

In January, 1909, Dr. J. W. Barrett organized a trip to the islands, 
and kindly invited Mr. Kershaw to join the party, with the object of 
searching again for the animal. Once more, owing to the very 
limited time available, the search proved fruitless, but we are 
much indebted to Dr. Barrett for his cordial co-operation. 

At the present time the matter stands thus : Evidence of the 
existence of a wombat is forthcoming in regard to King Island on 
the west side of Bass Strait, and Deal, Flinders, Barren, and Clarke 
Islands on the eastern side. Those of King, Deal, and Flinders 
Islands are specifically identical, and it may be taken for granted, 
as already said, that the same species inhabited Barren and Clarke 
Islands. The animal is now extinct everywhere except on Flinders 
Island. 

[ 48] 



EXISTING SPECIES OF THE OENUS PHASCOLOMYS. 



The specimen sent to Newcastle by Governor Hunter in 1798 
belonged to this species, and it was to this that Shaw referred when 
he described the animal that he calls DIdelpJnjs ursiua. At a later 
time other writers described the same species under other generic 
and specific names. In 1803, Geoffroy, ignorant of the fact that a 
specimen had been sent to England five yeare earher, and briefly 
described by Shaw under the name of Didelphijs ursina, proposed the 
generic name Phascolomys. The true designation of the wombat 
of the Bass Strait Islands is therefore Phascolomys ursinus, Shaw; 
and the following names, all of which have at one time or another 
been applied to the Island species, are synonyms of the former: — 

Wowbatus fossor, Desmarest (1803). 
Phascolomys wombat, Peron et Lesueur (1808). 
Amblotis fossor, lUiger (1811). 
Phascolomys jusca, Illiger (1811). 
Phascolomys vombatus. Leach (1815). 
Phascolomys bassii. Lesson (1827). 

The question now arises as to the relationship of Phascolomys 
iirsixus, the mainland species, and the Tasmanian species. There 
is no question as to the specific distinction of the hairy-nosed wom- 
bat, Phascolomys latifrmis, of South Australia. The remaining main- 
land form, Phascolomys mitchelli, is closely allied to the Tasmanian 
form, which again, up to the present time, has been supposed to be 
identical with the Bass Strait Island species, that is Phascolomys 
ursinus. In the following tables we give the measurements of the 
skull, teeth series, &c., of a series of Phascolomys from Bass Strait 
Islands, Tasmania, and Victoria, as well as a certain number of 
Phascolomys latifrons.

The structural peculiarities of P. latifrons, such as the very pro- 
minent post-orbital processes and the hair}- muzzle, serve to dis- 
tinguish it at once. In regard to the other three groups, the dif- 
ference is mainly one of size. It will also be noticed that, so far as 
the measurements are concerned, the Tasmanian species and P. 
latifrons are ver>' closely similar to one another. 

The Island species, the Tasmanian and P. mitchelli appear to 
represent three well-marked forms, so far as size is concenied. The

larger Island specimens, of course, approximate in size to the smaller 
Tasmanian ones, just as the larger Tasmanian ones do to the smaller 
P. mitcheUi. In the case of the Tasmanian form, one skull, for 
which we are indebted to Mr. H. H. Scott, curator of the Launceston 
Museum, is remarkable for its relatively large size. Its basal length 
is 163 mm., the next largest being 151 mm., but even this largest 
Tasmanian sloiU is slightly smaller in size than the smallest P. mit- 
cheUi, and it stands out as a giant amongst the Tasmanian specimens. 
When other bones, such as the humems and femur of the Island 
species (Plate 11, Figs. 9-14) are seen side by side with those of the 
Tasmanian form, the difference in size and in robustness of the bones 
is very marked, and they clearly indicate two animals of very dif- 
ferent form. 

The measurements of both the upper and lower tooth series serve 
also to mark the Island species as distinct. The maximum length 
of the upper tooth series of the Island species is 45 mm., the mini- 
mum of the Tasmanian species being 47 mm., and that of P. mitcheUi 
50 mm. The maximum of the lower tooth series of the Island species 
is 46 mm. ; the minimum of the Tasmanian form is 48 mm., and 
that of P. mitcheUi 52 mm. 

A reference to Plate 11, Figs. 1 and 2, illustrating respectively 
side views of the skulls of a King Island and Tasmanian wombat, 
serve to show not only the difference in size, but one or two features 
of structural importance in which they differ from one another. In 
the Tasmanian specimen (and the same is true of P. mitcheUi) the 
paroccipital process slants downwards and markedly forwards, in the 
King Island skulls it always runs nearly straight down, the forward 
slant being scarcely noticeable. A second point is that in the Island 
specimens the malar bone is always strongly bowed downwards and 
outwards beneath the orbit (cf. also Plate 9, Fig. 1, Plate 10, Fig. 1). 
In regard to thetwo specimens figured in Plate 11, it will be obser\"ed 
that the snout region in Fig. 1 is distinctly more elongate than the 
same part in Fig. 2, with the result that, seen from above the nasals, 
more completely hide the premaxillse from view in the Island than 
in the Tasmanian specimen. This feature, though it happens to be 
rather marked in the two examples figured, is subject to a certain 
amount of variation, and cannot be relied upon. 

The two skins obtained on Flinders Island measure respectively 
715 mm. and 675 mm., the latter being slightly incomplete. The 
hind foot of the first measures 65.5 mm. In the colour and general 
nature of its fur, the larger specimen, a male, is clearly similar to 
light-coloured specimens of P. mitcheUi or the Tasmanian fonn. In 
the smaller specimen each hair is light-coloured at the tip, giving a 
general light greyish-brown colour to the fur, the darker basal part 
of each hair being hidden from view. This basal part is much more 
darkly coloured than in the case of the other example. lu the 

[ ■''6 ]

smaller one also, the fur has a curious silkA- appearance, with small 
curlfi all over it, but it is c(»arse to the touch. There is also a lipht 
nisset-brown line along the back. 

In regard to the mainland species (P. mitcheUi) and the Tas- 
manian wombat, the difference in size is not so marked as it is in the 
case of the Island species when tlu' latter is compared witli either of 
the two former. The exceptionally large specimen of a Tasmanian 
wombat skull sent to us by Mr. Scott (Plate 0, Fig. 7) is so abnormal 
in size that we feel it would be misleading to take this as the nuixi- 
mum size of Tasmanian specimens without drawing attention to the 
difference between it and the largest of all the other Tasmanian skulls. 
A glance at the measurements detailed in Table 4 will sei-ve to show 
that this one is abnormal so far as Tasmanian wombats are concerned. 
We have therefore, in the summarized results of measurements, 
placed in brackets the Bgures referring to this skull and have taken 
the largest of the normal series of specimens as indicating what 
may be fairly regarded as the maximum size of Tasmanian 
wombats. 

In either case it is evident that, so far as size is concerned, the 
Tasmanian specimens form a group well marked off from those of the 
mainland, conunonly described under the specific name of Phas- 
colomys mitcheUi. As Mr. Oldfield Thomas* says—" The species 
seems to be well distinguished from Ph. mitcheUi by this one charac- 
ter of size, but otherwise there appears to be no difference of impor- 
tance between the two." 

As a result of the evidence now available we have come to the 
conclusion that four species of existing wombats must be recognised, 
as follows : — 

1. Phascolomys ursinus'\, Shaw. The oldest known species 

of the genus confined to the Islands of Bass Strait, 
and now extinct in all so far as known, except Flindei-s 
Island. This is considerably the smallest species. 
Type is the specimen sent to Newcastle by Hunter in 
"l798. 

2. Phascolomys mitcheUi, Owen. The largest species and the 

most common one on the Australian mainland. It 
extends over New South Wales, A^ictoria, and South 
Australia. The head and body measure 950-1150 mm. 
The basal length of the skull measures 160-180 mm. 
Type (fossil) in Museum of the Geological Society, 
London.

3. Phascolomys latifrons, Owen. Characterized by the soft 

silky fur, hairy rhinarium, and prominent post-orbital 

processes. 
Habitat, South Australia. 
Type in the Museum of the Royal College of Surgeons. 

4. Phascolomys tasmaniensts, sp. n. Size medium, inter- 

mediate in this respect between Ph. mitchelli and Ph. 
ursinus. Total length of the head and body 910 mm. 
Except in size it agrees closely in external form with 
Ph. mitchelli. Colour grizzled grey. Underfur fairly 
abundant, especially on the anterior part of the body. 

Hairs within the ear light coloured. 

Basal length of skuU,* 141 mm. ; greatest width, 116 mm. 

Type (male) in National Museum, Melbourne. 

Specimens vary somewhat in size, the smallest mature 
female in our possession having a total length of 
780 mm., the largest female measuring 910 mm. 
One male measures 878, and a second (the type) 910 
mm., which is probably about the maximum size of 
the male form, the female reaching a length of 
950 mm. 

The variation in colour is very considerable, from grizzled 
grey to black. In melanistic specimens the distal 
half of the long hairs is black, the proximal half dark- 
brown; the underfur is also dark-brown, but it is 
completely, or almost completely, hidden from sight 
by the black tips of the abundant long hairs. The 
hairs within the ear are dark-brown in colour. The 
general colour of the majority of specimens is grizzled- 
grey, with, at times, brownish or russet tinged areas. 
The grizzled appearance is due to the fact that the 
majority of the hairs are tipped with white, and these 
are interspei-sed with long, coarse, dark-tipped hairs, 
varying in number in different parts. They are fre- 
quently abundant enough to give a general dark colour 
to certain areas, such as the middle line of the back. 

The underfur appears to be always noticeably thicker on 
the anterior part of the body, especially in the shoulder 
region. 

In aU specimens, excepting melanistic ones, the hairs 
within the ear are always light-coloured, sometimes 
almost white. The chin is brown, throat and chest 
uniformly light-coloured. There is considerable varia- 
tion in the coarseness of the hair which is not generally 
so harsh as in Ph. mitchelli. ,/

EXISTING SPECIES OF THE GENUS PHASCOLOMYS. 



In the following list we have enumerated the more important 
memoirs, &c.. dealing with the genus Phascolomys, and have given 
a brief outline of thoir contents, so far as they are concerned, with 
the history of the species included in the genus. 

1. Bewick. — History of Qnadrwpeds, 4th edit., p. 522, 1800. 

Contains in full the letter written by Hunter, accom- 
panying the body of the wombat from Clarke Island 
sent to Newcastle. Above the letter is a figure of " the 
Wombach." 

2. Shaw.— General Zoology, 1, Pt. 2, p. 504, 1800. Gives a 

short description of, presumably, the animal sent to 
England by Hunter (as no other was then known) 
under the name of Didelphys ursina. 

3. Collins. — Account of the English Colony in New South 

Wales, 1st ed., vol. ii., p. 153, 1802. 2nd ed., 1804, 
p. 466. Includes a description of a wombat found by 
Bass on Cape Barren Island. The description of the 
teeth is wrong. The animal is figured, the drawing 
being remarkably similar to the one in Bewick. 

4. Geoff roij. — Annales du Museum d^histoire naturelle, vol. 2, 

1803, p. 264. Contains a preliminarv description of 
certain animals collected on Baudin's expedition. 
The generic name of Phascolomys is proposed for the 
wombat. Reference is made to the animal described 
by Bass and to the nature of its teeth. 

5. Desmarest.—N. Diet, d'hist. nat., xxiv., p. 14, 1803. 

Refers to the animal described by Bass, and calls it 
Womhattus fossor. 

6. Sevastianof. — Mem. de VAcad. de St. Petersbourg, i., 1807, 

p. 443, PI. 17. Describes a skin sent to the Museum 
in St. Petersburg, and says that it is the same species 
as the one discovered by Bass and Flinders. 

7. Peron et Freycinet. — Voyage de Decouvertes aux Terres 

Australes, Vol. i., letterpress, 1807 ; atlas, 1st part, 
1808. Gives an account of the finding of wombats 
on King Island by the naturalists of Baudin's expedi- 
tion. Plate 28 (Ist edit.) represents light and dark 
varieties of the animals together with young ones, 
drawn by Lesueur. The animal is called Phascolomys 
wonbat. and the locality given is King Island. 

8. Home.— Trans. R. S., 1808, p. 304. Contains a description 

of the anatomy of a male wombat. It was one of 
those taken to England from King Island by Brown, 
and lived in a domesticated state for two years. 

[ 5i' ] 



EXISTING SPECIES OP THE GENUS PHASCOLOMYS. 

9. Illiger. — P/odromus Syst. Mamw. et Avium, 1811. pp. 77, 
78. Refers to what is evidently the species sent to 
France from the Bass Strait Islands under the name 
of Phascolomys fusca, and proposes the genus Amblntis 
for Bass' animal, in consequence of the wrong descrip- 
tion of teeth given by Collins. 

10. Flinders. — A Voyage to Terra Australis, vol. i, p. 206, 

1814. Describes the finding of wombats on King 
Island in April, 1802. Some were taken to England 
by Brown. 

11. Leach. — Zoological Miscellany, p. 102, PI. 96, 1815. Gives 

a very brief description of the animal, which he calls 
Phascolomis vombatus, together with a figure. He 
mentions Bewick's and Home's accounts as referring 
to the same animal, the usual length of which he says 
is 2 feet. 

12. Cuvier {G.).—R('gne Animal Tome i., p. 184, PI. 51, 1817. 

Says that only one species is known; it is the size of 
a badger, lives on King Island, and is identical with 
Shaw's Didelphis ursina. Figures a brown variety from 
a stuffed specimen in the Paris Museum. 

13. Lesson and Garnot. — ^In Duperry Voyage autour du Monde, 

Tome i., p. 399, 1826. The authors say that they 
could only secure one skin of the wombat in Sydney, 
and that it is only known from the southern coasts of 
Australia and the Islands of Bass Strait. 

14. Owen. — Catalogue, Royal College of Surgeons, 1831. Gives 

the distribution of Phascolomys wombat as " King 
Island, and near Port Jackson," and makes no 
reference to Tasmania. 

15. Owen. — P.Z.S., p. 49, 1836. Description of the anatomy 

of Phascolomys wombat that had lived in the gardens 
for five years and weighed 59j lbs. 

16. Gunn.— Annals Nat. Hist.,Yo\. i..p. 103, 1838. Says that 

Phascolomys, the wombat, is commonly known as the 
badger, and is found in various parts. One that he 
caught measured 36 inches in length and 34 in circum- 
ference. 

17. Gray.— Annals Nat. Hist., Vol. i., p. 107, 1838. In a note 

appended to Gunn's paper (15) Gray says that he has 
seen Bass' specimen at Newcastle, and that it was the 
same "as the one we now usually receive from \an 
Diemen's Land " (The specimen was Hunter's, not 
Bass').

Much to our regret we overlooked the description of a 
new species of hairy-nosed Wombat pulilished by ^Ir. C. W. 
(le Vis in the Annals of the Queenshmd Museum, No. 5, 
p. 14, lyOO. Mr. de Vis' description is based upon two 
entire specimens and a skull secured at St. George, on the 
Moonie River, in South-eastern Queensland, close to the New 
South Wales border. Externally it is indistiuguishalile from 
the South Australian species, Phascolomi/s lutifrons, but Mr. 
tie Vis, as the result of certain cranial peculiarities, regards 
it as distinct from the latter. In the collection of the 
National Museum, Melbourne, we have three skins, a stuffed 
specimen, and skulls of a hairy-nosed Wombat from Deniliquin, 
in the southern part of New South Wales, close to the 
Victorian border. One of us,* since this paper has been in 
print, has recorded these under the name of P. latifrons, thus 
widely extending the distribution of the species. In regard 
to the ])roportion3 of the skull, the shortness of the frontals, 
the pronounced ramification of the naso-frontal suture, and 
the l)ackward cuneiform extension of the same, our Deniliquin 
spc'cinicn agrees to a large extent with those of Mr. de Vis, 
for which he has jiroposed the name of Pliascolomys ^illespiei, 
but we feel consideral)le doul)t as to whether either the 
Queensland or the New South Wales form is specifically 
distinct from /'. latifroiis.

AN INDEX TO THE LAND SHELLS OF VICTORIA. 

By J. C. Cox, M.D., and C. Medley, F.L.S. 
(Plates I., II., III.) 



At the invitation of the Director of the National Museum, Mel- 
bourne, we have undertaken a brief survey of the land shells of 
Victoria. ]\Iaterial from the National Museum and from the private 
collection of Mr. J. A. Kershaw has been confided to us. We have 
also drawn upon the resources of the Cox collection and of the 
Australian Museum, Sydney. Previous studies on the Tasmanian 
land shells* by the late Mr. W. F. Petterd and one of us, formed a 
suitable introduction to the present task. 

But little attention has yet been paid to the land molluscan 
fauna of the State. Recently Dr. T. S. Hall wrote, " As to our land 
and fresh water moUusca, again, we in Victoria are sadly in the 
dark. Collecting has been done in the south-west of the State, but 
the rest is a blank."f Although the search has not been exhaustive 
and several species doubtless await discovery, sufHcient has been 
done to show that Victoria is poorer in land shells than other parts 
of Australia. Professor Tate, in discussing this remarkable paucity, 
suggested that " A deluge of igneous mass must have destroyed 
terrestrial forms of life over the greater part of the southern region 
of Victoria. "J 

Probably the first conchologists to work in Victoria were the 
naturalists of the Astrolabe, who, in 1826, visited Western Port and 
found Helicarion cuvieri and Succinea australis. In 1868, but five 
species, including two lately collected by Mr. G. Masters, were 
recorded from Victoria, in Dr. Cox's Monograph of Australian Land 
SJidls. A few more species have since been added by desultory 
collecting. In the earliest paper written exclusively on the moUuscs 
of Victoria, Mr. Maplestone observed the scarcity of land shells 
around Melbourne.§ In 1884, Professor Tate published a list and 
general discussion of the land shells. It was his intention to 
complete this preliminary statement by a more detailed study, 
but the increasing pressure of an active life gave him no further 
opportunity of resuming the subject. 

An account of the land and freshwater moUusca of Castlcmaine 
was more recently published by Mr. F. L. Billinghurst.|| 

During the preparation of this report, our friend the veteran 
conchologist, Mr. W. F. Petterd, passed away. He took a keen 
interest in the subject, and had generously assisted us with speci- 
mens and information.

All known Victorian species have now been illustrated, and the 
present index to the subject will enable students to identify them. 
But it is to be remembered that smaller and rarer species yet await 
discovery, and that the structure of some of the small forms also 
requires investigation.

After Panda and Paryphanta, this is the largest Victorian snail. 
When deprived of its characteristic bristly epidermis, it seems 
transformed into another species. It is obvious that this is what 
Professor Tate doubtfully recorded* from Fernshaw as H. mansueta, 
Pfr. The latter is a Queensland shell hearinp a general resemblance 
to C. victoria' in size, form, and ccjlour. But ('. mimsueta may be 
distinguished in all stages of growth by the broader umbilicus and 
sparser bristles. Professor Tate's record (op. oit.) of //. brevipila, 
Pfr., from Melbourne is evidently again a misquotation for C. Vic- 
toria;. During the preparation of the Revised Census of the Terres- 
trial Mollitsca of Tasumnia, Mr. W. F. Petterd was not quite satisfied 
of the identity of C. hrunonia with C. victoria'. In the last letter we 
received from him, he had decided that they were the same. This 
decision is here adopted. The species seems to be common and 
widely distributed. We have received specimens from the fol- 
lowing places : — Western- Port (type locality. Masters and Petterd), 
Victorian Alps (French), Jan Juc (Kershaw). Forrest (Steel), Lome 
(Pritchard), Loutit Bay (Kershaw), and Cape Otway (Petterd). 
Beyond Victoria it is only known from King Island, and from Mt. 
Kosciusko.

that " specimens from the Dandenong Range, Victoria, are identical 
with those from the northern portion of this island "f, ic-- Tasmania. 

Professor Tate appears to have considered, on the contrary, that 
mainland shells should be specifically distinguished from the Tas- 
manian. and proposed to name the Victorian form, which he recorded 
from Sale, Cape Otway, and P'emshaw, as Helix exoptata, but he 
never published a formal description or noted differential characters. 

The size principally distinguished R. ruga from its northern 
relations, and it may prove a dwarf of a widespread species which, 
in different parts of Australia, has received different names. We

Colour brown, deepening on the last whorl to black and on the 
second whorl passing into straw yellow. The epidermis, in which 
the colour resides, is thick and very glossy. Sculpture : On the 
earlier whorls are obhque wrinkles, on the later a few irregular 
growth lines occur. Suture deeply impressed. Spire slightly ele- 
vated, base well rounded, umbihcus a narrow perforation. Aperture 
very oblique, slightly descending above, sinuate at the peripher}', 
left insertion a little reflected over the perforation. Margins united 
by a callus which within the throat is purple and finely granulated. 
This callous lining does not extend to the very edge of the aperture, 
but leaves a narrow epidermal margin.

collected by Mr. A. D. Hardy in debris and rotten wood at Smithers 
Creek, Otway Ranges. Three other specimens collected by Mr. 
Kershaw at the Erskine Falls, Loutit Bay, differ by being smaller, 
namely : — Maj. diam., 20 mm. ; min. diam, 15 mm. ; height, 14

The novelty is nearest in the genus to P. atramentaria, but with 
as many whorls in about half the diameter, the whorls increase 
more slowly, the last whorl is proportionately smaller, the perfora- 
tion narrower, and the whole shell more globose. In size it re- 
sembles the Tasmanian P. fumosn, but the whorls of compacta are 
wound more noarly in the same plane and increase less rapidly. It 
seems confined to the southern part of the State, while atramen- 
taria inhabits the centre.

Helix juloiden, Forbes, voy. Rattlesnake, Append., p. 319,pl.ii.,f. 4. 

The type of this species was found at Port Molle, in tropical 
Queensland, so that the shell is very unlikely to occur also in Tas- 
mania or Victoria. Professor Tate recorded (Trans. Roy. Soc, S.A., 
IV., 1882, p. 75) juloidea from Victoria, but specimens which he 
80 determined prove to be E. funerea. The Melbourne shell which 
Tenison Woods (Proc Linn. Soc, N.S.W., III., 1879, p. 125) called 
juloidea was probably E. albanensis.

E. murrayana is related to E. funerea, than which it is larger, 
flatter, with wider umbilicus, and more distant radial lamellse. It 
has not hitherto been recorded from Victoria. Some exampleji 
from Geelong, collected by Dr. T. S. Hall, have a narrower umbilicus 
and weaker closer radial riblets than typical shells from the Murray 
cliifs. For these we adopt the varietal name of suhmurrayana, 
which Professor Tate proposed to bestow when he had this form 
under consideration. A specimen in the Australian Museum here 
figured is, major diam., 6 '5 mm. ; minor diam., 5 mm. ; and height, 
3 '5 mm.

Professor Tate has quoted other Victorian localities, but since 
that of Melbourne (on the authority of Pettcrd) refers to L. mucoides, 
we regard them as uncertain. 

Laoma mucoides, Tenison Woods.

Id., Tate, Trans. Roy. Soc., S.A., IV., 1882, p. 75. 

L. mucoides is closely related to L. morti. Cox, in form and sculp- 
ture, and has in the past been mistaken for it. L. mucoides has an 
extra whorl, and is larger, darker, and more solid. In L. morti the 
radial lamclljc arc better developed. One of Tenison Woods' type 
specimens here figured is 2 "8 mm. maj. diam., 2 '35 mm min. diam., 
and 1 '35 mm. in height. The type locality is Melbourne.

Laoma pictilis, Petterd and Hedley, Rec. Austr. Mus., VII., 1909, 
p. 294, pi. Ixxxvi., f. 35-37. 

Cape Northumberland, the type locality of //. pictilis, is but a 
short distance from Penola, where the type ftt H. penolensis was 
found. Professor Tate distinguished H. pictilis from the Penola 
shell by "its coarser ribbing, its colouration, and the presence of 
transverse stria?." The first and second characters are variable, and 
we find that the type of H. penolensis in the Cox collection has micro- 
scopic spiral striae. So that //. pictilis may be safely reduced to a 
synonym of //. penolensis.

The type which Mr. Petterd presented to the Australian Museum, 
and which measures, maj. diam. 7 '5 mm., min. diam. 6 mm., 
height 5 "5 mm., is here figured. The H . fernshawensis is Tega,T:ded 
by us as a lost species, for Mr. Petterd had retained no specimen of 
it, neither is an example preserved in the Tate collection, as Dr, 
Verco kindly informs us. We have taken advantage of Professor 
Tate's suggestion, that H. fernshawensis is an immature H. m'coyi, 
to suppress it as a synonym. 

Habitat. — Dandenong Kange (Petterd), Fernshaw (Tate), Don 
River (National Museum), Upper Yarra (Kershaw). 

Flammulina elenescens, sp. nov. 

(Plate III, Figs. 16, 17, 18.) 

Shell subdiscoidal, thin, spire slightly elevated, base flattened 
and broadly umbilicated. Colour ochraceous-bufi, with a few faint 
radial streaks of brown. Whorls five, slowly increasing, parted by 
deeply impressed sutures. Sculpture : First whorl and a half smooth, 
about the ante -penultimate whorl the shell is ornamented with fine 
close even thread-like radials at the rate of about a hundred to a 
whorl, this sculpture is also visible within the umbilicus. On the 
later whorls this sculpture gradually vanishes, so that their smooth- 
ness is only broken by fine and rather irregular growth lines. There 
is no spiral sculpture. Umbilicus about a quarter of the shell's 
diameter, broad and open, exposing all the earlier whorls. Maj. 
diam., 6 "7 mm. ; minor diam., 5 '4 mm. ; height, 2 '9 mm. 

Habitat. — Merri Creek (Tenison Woods). Type in the Australian 
Museum. 

In general appearance the novelty is like F. diemenensis and F. 
marchiancB, between which it is intermediate in size. The break in 
sculpture of F. elenescens readily distinguishes it.

Flammulina meraca, sp. nov, 

(Plate in.. Figs. 19, 20, 21.) 

Shell small, very thin, subdiscoidal spire slightly elevated, base 
narrowly perforated. Colour pure white. Whorls three and a half, 
parted by deep sutures and rather rapidly increasing. Scidpture: 
The protoconch, of one and a half whorls, is finely spirally striated 
and ends abruptly, the adidt shell is perpendicularly traversed by 
fine evenly spaced radial riblcts, amounting on the last whorl to 
about two hundred, between the riblets are a few very minute 
radial threads. Aperture lunate-ovate, columella slightly reflected. 
Inner lip overlaid by a callus spread in advance over the riblets of 
the preceding whorl. Base rounded, umbilicus narrow, about 
one-fifteenth of the major diameter. Height, 2 mm. ; maj. diam., 
4 mm.; minor diam., 3 mm. 

Habitat. — Dandenong Range, numerous specimens (Kershaw), 
and Fernshaw (Petterd). Type from the Dandenongs in the

The novelty is nearest related to F. nirea, Hedley,* from Kos- 
ciusko, which differs in the microscopic details of the sculpture, 
is more closely coiled, and has a sunken instead of an elevated spire.

ON SOME TYPES OF LEPIDOPTERA IN THE NATIONAL 
MUSEUM, MELBOURNE. 

By A. Jefferis Turner, M.D., F.E.S. 



In a little work published in 1869 under the title Characters 
of Undescribed Lepidoptera Heterocera, by the late Mr. FrancLs 
Walker, F.L.S., are the descriptions of a number of .species which 
it is desirable to identify as far as possible. The work commences 
with 102 species described as new from the collection of T. Xorris, 
Esq. Of these, eight are stated to have been taken at Moreton 
Bay, but a large proportion of the species are without locality, so 
that it is quite possible that there are more Australian types among 
them. Whether these types are still in existence I do not know, 
but I believe I have seen some of them in the British Museum. 
I have made an attempt to identify the Australian forms from 
the descriptions. 

12. Lithosia remota is a synonym of Lexis nitens, Wik. 

24. Turriga invasa is probably a variety of Olene mendosa, Hb. 

26. Entometa adusta is a synonym of Pinara metaphaea, "Wlk. 

32. Doratifera congrxm is a synonym of Susica alphaeo; Fab. 

33. Mecytlm antiqua I have not been able to identify. 

37. Anthercea insignis is a synonym of Copaom janetta. White. 
81. Plana lignificta, and 88. Hypopyra fusifascia, I am not 
able to identify. 

The next instalment is headed " The following fifty-one species 
inhabit Australia, and are in the National Museum at Melbourne." 
Through the courtesy of Mr. J. A. Kershaw, the Curator, I have 
had the opportunity of carefully examining these types. They are 
kept in a drawer by themselves, and have been well cared for, but 
bear the traces of previous ill-usage. Mr. Kershaw informs me 
that they were placed in this drawer from a box, which contained a 
label saying that they were " received in bad condition," probably 
from damage in the post. Beneath each type is an M.S. name, 
probably in Walker's handwriting, and these names correspond 
to the descriptions in print. Two of the types are missing, but 
one of these I have identified to my own satisfaction from the de- 
scription. The remaining forty-nine are all Victorian species, or 
at least forty-seven of them, which I have determined. Of the 
two remaining, one is an obscure species of the genus Anthela, which 
will probably be identified some day ; the other is represented by 
thorax and hind wings only, and all that can be said of it is that it 
is a species of Agriophara. Forty-eight of the species are now 
accounted for, and of these forty-eight names, thirty-one are 

[16] 



TYPES OF LEPIDOPTERA. 



s\Tionyms. most of the species having been previously named by 
Walker himself. There remain seventeen names which nuLst, I 
think, be adopted. Most of these have been since described by 
other authors, who had not the opportunity of examining Walker's 
types. Of the four generic names proposed, none are valid. 

I should not have been able to obtain results so complete if it 
had not been for the generous assistance of Mr. J. A. Kershaw and 
Mr. Geo. Lyell. The latter went through the types before my 
arrival, and left me a box of examples from his own collection, which 
he had compared and identified with tlu'in. The former supple- 
mented these with other examples from the Museum collection. 
Having satisfied myself of the correctness of the identifications, 
and in some instances this required special care, I was able to study 
the loaned examples at leisure after my return to Brisbane. 

My detailed results are as follow : — 

1. Eterusia auroatra. — The tvpe is unfortunately missing. 

The description applies to some species of unusually 
distinct appearance, and should be recognisable, but 
at present I cannot identify it with any Australian 
species known to me. 

2. Eutane partita. — This is a good species correctly identified 

by Sir Greo. Hampson, and described as Thallarchu 
partita (Cat. Lop. Phal. II., p. 503). There are 
several allied and very similar species ; this one is 
best distinguished by its deep orange-ochreous ground- 
colour, and by a fuscous spot in cilia of hind winge 
below middle. It appears to be very rare in collec- 
tions ; a specimen lent me from the National Museum 
bears the locality label Spring Vale, Victoria. I have 
taken a series, which I refer to this species, at Glen 
Innea, New South Wales, in October. 

3. Castula binotata = Castulo doubledayi, Newm. = Cluaca 

TuhricoHta, Wlk. The type of binotata is a variety 
occasionally met with in which the termen and cilia 
of hind wings are ochreous, with a narrow dark-fuscous 
subtenninal line. 

4. Orgyui semifusca is, I think, a good species, but cannot 

be referred to this genus. The i agrees structurally 
with Portheaia, but Mr. Kershaw has lent me a 9 from 
the National Museum which strikingly resembles a 
? Orgyia. I propose to make this species the type of 
fl. new genus Ocybola, and both genus and species will 
be described below. 

5. Tenra luctipennis is a synonym of Oenosandu boisduvalii, 

Newm. i . This species is sexually dimorphic.

TYPKS OF LEPIDOITERA. 



6. Entnmeta despecta. — The type is a ,J and liliould be easily 

recognised ; the hind wings are blackisli and much 
darker than the fore wings, which are bnAvn, densely 
irrorated with orange-ochreous. I have this species 
under the name of Entometa obscura, Wlk. Walker's 
types of this genus require to be elucidated, 
the ? 9 of many of the species are very similar, and 
unfortunately some of the types are ? . 

7. Entometa iqnobilis belongs to the Ps?/cAi(toe, and has been 

correctly identified by Meyrick and Lower (Trans. 
Roy. Soc. S.A., 1897, p. 197), who redescribe it as 
Clania ignohilis. 

8. Ptilotnacra antiqua is a synonym of Ptilornacra senex, Wlk. 

9. Opsirrhina punctilinea is a synonym of Pinara divisa, 

Wlk. 9 . 

10. Tolype subnotata is a good species so far as I know. It 

is closely allied to trimacula, AYlk., which Mr. Lyell 
tells me is the 9 of Crexa punctigera, Wlk. I suspect 
that my Creoca hyaloessa may be the i of subnotata. 

11. Hepialus fasciculatus is a synonym of Oncoptera intricata, 

Wlk. 

12. Leucania adjuncta is a synonym of CirpJiin ciliata; Wlk. 

It is not the same as the species described by Hamp- 
son as Cirphis adjuncta (Cat. Lep. Phal. V., p. 489), 
for which I propose a new name below. 

13. Mamestra confundens is a synonym of Dasygaster hol- 

landice, Gn. 

14. Agrotis costalis is a synonym of Caradrina tortisigna, Wlk. 

15. Agrotis transversa = Euxoa porphyricollis, G-n. 

16. Anclioscdis bicolor = Agrotis compta, Wlk. 

17. Orthosia deprivata is a slightly darker example of Agrotis 

compta, Wlk. 

18. Euplexia inamestroides has been described by me as 

Prometopus poliophracta. (Trans. Roy. Soc. South 
Australia, 1908, p. 57.) Hampson identifies this 
species as Omplialetis exundans, Gn. (Cat. Lep. Phal. 
VIII., p. 377.) It is very similar in markings to 
Caradrina instipata, Wlk. 

19. Xylina saxaiilis ^^ Ectopatria subrufescens, Wlk. 

20. Pantydia canescens = Pantydia diemeni, Gn. 

21. Samea distractalis = Nacoleia rhoeonalis, Wlk. The 

type is mangled, but recognisable. 

22. Ebulea gavisalis has been since described as Mecyna 

rhodochrysa, Meyr. 

23. Stenopteryx corticalis = Nomophila noctiteUa, SchifE. 

24. Idiodes inornata = Idiodes apicata, Gn. 

26. Azelina inordinata = Mnesampela privata, Gn. 

[18] 



TYPES OF LEPrnOPTEKA. 



Bx 



26. Azelinn bipla^ga is a good species, which has been re- 

described as Metrocatnfa glaucias, Meyr. 

27. Passa pi/gaeroides = Smyriodes nplectaria, Gn. 

28. Monoctenia decora is a pale variety of Monoctenia 

vinaria, Gn. 

29. Arnissa simplex belongs to the genus Anthela (Lyman- 

friadne). The type is an obscure ? , and I Was not 
able to identify the species. 

30. Tephrosia scitiferata = Selidosema mundifera, \\\k. 

31. Tephrosia fulgurigera ^ Selidosenm excursaria, Gn., a 

variety with tliickened dark-fuscous lines on wings. 

32. Asthena vexata = Euchoeca rtibropuncturia, Wlk. 

33. Macarin comptaia = Diastictis auslraliaria, Gn. 

34. Larentin approximata has been since described as 

Phrissogonus pyretodes, Meyr. Tlie type is a <J and 
rather ilarker than usual. 

35. LarerUia gdidata (Walker's M.S. label reads " Larentia 

cdgidata ") is a s example of Xanthnrhop subidaria. Gn. 

36. Oesymnti. stipataria is a 9 example of Microdes squumu- 

laUi, Gn. 

37. Eupithecia destructata has been since described as Phris- 

sogomis catastreptes, Meyr. In this instance only I 
had no example to compare with the type, but I am 
confident of my identification. 

38. Acrobasis subcvltella = Epipaschia nauplialis, W'\k. 

39. Hypntxi moderatella = Chlenias arietaria, Gn. 

40. Dichelin vicariana = Caccecia postvittana, W]k. 

41. Sperchia intractana is, I believe, the species described by 

Meyrick under the name of Capua obfuscatana. 

42. Tinea annosella has been since described as Xysmatodona 

saxosa, Meyr. 

43. Tinea arctiella lias been since described as Lepidoscia 

comocJiora, Meyr. 

44. Tin&t nivibractdla is a good species of the genus Monopis, 

Hb. I give a full description below. 

45. Tinea intritdla has been redescribed as Phloeopola 

exarcka, Meyr. 

46. Hyponometita ? viduata is a good species which may be 

j)nivisi((nally referred to the genus Xylorycta. Besides 
the type there are three examples in the National 
Museum, all imperfect and without palpi. (Localities: 
Melbourne and K<'well, Vic.) 

47. Chinutbacche saxipenneUa. This is, I have no doubt, a 

species oi the genus Agriopkara, but as the type has 
now no fore wings, palpi, antennae, nor abdomen, it 
Would be rash to identify it more particularly. 
[ 19] 



TYPES OF LEPIDOPTERA. 



48. Gelechia improbella is a species of the genus Eulechria. I 

have not been able to identify it with any of Mr. 
Mey rick's descriptions, but it is a species difficult to 
recognise. I describe it below. 

49. Gelechia genimipunctellu is represented by a single fore 

wing only, but this is sufficient to identif}' it with 
Glyphipteryx atristiella, Zel. I consider G. chry- 
solitliella, Meyr., to be the same species, the colour of 
the hind wings being variable in different localities. 

50. Oecophora impletella. The type is missing, but from 

the description I have no hesitation in identifying 
this with Philobota herodiellu, Feld. As vol. ii. of 
the Reise Novara was published in 1874, Walker's 
name has the priority. 

51. Cryptolechia scitipunctdla is a synonym of Hoplitica 

repandula, Zel. 

In the National Museum is the Curtis collection of British insects. 
Among them I examined Arctunis sparshaUii, Ciirt., which is un- 
doubtedly the same as Trichetra stihosma, Butl. Mr. Lyell informs 
me that he considers this to be a varietal form of Trichetra melanosoma, 
Wlk. How this Australian insect came to be ascribed to Great 
Britain must remain a mystery. 

In the Museum Library I had an opportimity of examining 
Donovan's Insects of New Holland. His Tinea strigateUa (Plate 40) 
is the same as Philobota chrysopotama, Meyr. The only discrepancy 
is that the ground-colour is figured purple, but comparison with the 
description shows that this is an error of the colourist. 

Genus Ocybola, nov. 

wicvfioXoc, quick-darting. 

Head and thorax densely long-haired. Tongue minute. Palpi 
moderate, porrect, hairy. Antennae in i with two rows of long 
pectinations to apex, in ? shortly bipectinate. Legs hairy, pos- 
terior tibiae with two pairs of spurs. Abdomen without crests. 
Fore wings with 2 from middle, 3 from before angle, 4 and 5 from

scanty blackish irroration, external surface of palpi in S purplish 
tinged. Antenna- grey, towards base grey-whitish ; ciliations in i ^, 
bristles 1. Abdomen grey-whitish. Legs whitish, with sparse 
blackish irroration ; anterior femora in S densely hairy and anterior 
tibiie with immense fuscous-puqjle tufts. Fore wings elongate- 
triangular, costa nearly straight ; apex roimded, termen scarcely 
oblique, rounded beneath ; grey-whitish with sparse blackish 
irroration, and sometimes some patchy purjjle-grcy suffusion; 
a white postmedian discal dot immediately preceded by a blackish 
dot ; a row of dark-fuscous dots at ^ parallel to termen ; a series 
of minute terminal dots ; cilia grey-whitish, tinged with purplish, 
with a fuscous subapical line. Hind wings with termen wavy ; 
whitish, towards termen suffused with fuscous ; cilia whitish, 
purplish-tinged except towards tornus, with a fuscous median line. 

Very similar to Cirphis ciliata, Wlk., from which it may be 
readily distinguished (1) by the i fore legs, (2) by the postmedian 
line on fore wings being single, not double.

or ochreous-fuscous irroration ; cilia dark-fusoDus, on rnid-tertncn 
and tornus white. Hind wings lanceolate ; grey ; cilia pale-ochreouB, 
at apex grey. 

This species is very similar to Monopis meliorella, Wlk., with 
which it has been confused. For some years I have recopniscd its 
distinctness, and am glad to take this opportunity of describing it. 
The best point of distinction is the broad dark-fuscous band between 
dorsal white spot and base and costa. Both species are common 
and widely distributed.

CATALOGUE OF THE VICTORIAN CICADID^ IN THE 
NATIONAL MUSEUM. MELBOURNE. 

By Howard Ashton. 
(Plate TV., Figs, b, d— h, j, k.) 



During my investigations into this group T have been afforded 
frequent opportunities for examining the collection contained in 
the National Museum, Melbourne, and, acting on the suggestion of 
the Curator. T have drawn up the following catalogue embracing 
all the Victorian species in the Museum. In the collection are a 
number of specimens determined by Walker; also a number deter- 
mined by Goding and Froggatt, together with some of their types. 
\\Ticre there is any doubt of a species, I have followed the deter- 
minations of Distant, since he has all the material at his dispo.sal, 
and has recently systematized the family in a thorough and admirable 
manner. Several of the species in my own collection have been 
determined by him, and, having these, I havefound occasion to differ 
a little from other workers in the familv. I have to thank the Curator 
of the Zoohjgical Department, Mr. J. A. Kershaw, for facilities 
afforded me during the examination of the collections, and for the 
loan f)f several specimens. In addition to the references given here, 
may be understood in each case those of Distant's Catalogue of 1906.

By Howard Ashton. 
(Plate IV., Figs, a, c, i.) 



While engaged in tlie preparation of the Catalogue of Victorian 
Cicadidee in the l^ational Museum, the following species were found 
to be new. 

These, with the consent of the Director, Professor Baldwin 
Spencer, I am now enabled to describe and figure. 

Family Cicadidse. 

SUB-FAMILY CICADIN>E. 

Division Cicadaria. 

Genus Macrotristria. 

Macrotejstria dorsalis, sp. NOV. (Fig. a, 1, 2.) 

Male. — Body above ochraceous, mesonotum tinged with 
brownish, in fresh specimens probably greenish. Central sulcus 
to vertex of head, a short longitudinal and anteriorly angulate spot 
on each side of region of ocelli, and anterior margins to eyes 
and basal margin of front very narrowly black. Abdomen with a 
broad central dorsal longitudinal fascia extending from base, where 
it is very wide, and narrowing sharply to penultimate segment ; 
base of apical segment and spot on anal appendage piceous or black. 
Face and head beneath, bright ochraceous ; sternum, opercula, and 
legs sordid ochraceous brown ; anterior and intermediate tarsi and 
disc of abdomen beneath warm fuscous. Tegmina and wings hyaUne, 
talc-like ; tegmina with costal membrane and area and basal half of 
venation ochraceous ; postcostal area and apical venation fuscous, 
and claval nervure black ; wings to basal two-thirds of venation pale 
ochraceous, apical veins light fuscous. Head (including eyes) equal 
in breadth to lateral dilations of posterior pronotal margin. 
Abdomen much shorter than space between apex of head and base 
of cruciform elevation ; rostrum with tip piceous, barely reaching 
posterior coxae. Lateral areas of abdomen much depressed. Long., 
male 25 mm., female, 23 mm. ; exp. teg. 75 mm.

specimens. (Presented by R. W. Armitage, 1908.) 

Allied to M. intersecta, Walk., and M. sylvanella, G-od. and Frogg., 
but differing in the shorter abdomen and overlapping opercula. 
Differing also from M. extrema, Dist., by the narrower head and 
thorax. The dark fascia on the dorsum renders it easily identifiable.

ON A NEW RHYTIPHORA IN THE NATIONAL MUSEUM, 

MELBOURNE. 

By Arthur M. Lea, F.E.S. 



Some time ago, Mr. C. French sent for examination a very large 
Rhytiphora, with the. request that 1 should describe it if new. This 
it appeared to be, and I would gladly have described it then, but 
thinking it possible that such a fine insect would not have escaped 
description if in other entomologists' hands, and that the Zoological 
Records are usually about two years behind in their records, I 
deferred describing it till after hearing from Mr. C. J. Gahan, of the 
British Museum, to whom I wrote. In the interim I returned the 
specimen to Mr. French, and he gave it to the National Museum, 
from whence, at my re(|uest, I have again received it. 

The species is certainly allied to R. dallasi, but is even more 
magnificent than that fine species, from which it differs in being 
considerably larger, the clothing denser, somewhat differently 
disposed, and not uniformly silvery. The most noticeable difference 
is in the elytral costae; counting the suture as the first, then the 
third and fourth (jn each elytron are conjoined close to apex, with 
the space between densely clothed with ochreous instead of silvery 
pubescence, and the space equal to or even more than the space 
between the second and third. In dalla.fi, the third and fourth are 
not conjoined at apex, and the space between them is much less 
than that between the second and third. On the prothorax, the 
dark transverse lines are two in munber instead of four, as in dallasi. 

Mr. Gahan wrote — " I have not described nor do I know any 
species of Rhytiphora answering to the description you have sent 
me. It appears certainly to be distinct from dallasi. In all our 
four specimens of dallasi, the white elytral band between the third 
and fourth costte is very narrow, barely more than a line, and in 
one specimen it is partly broken up into spots. I notice that in 
the male of dallasi there is no pubescent depression at each side 
behind the posterior margin of the first abdominal segment, as there 
is in most <>i the other species of Rhytiphora. But this sexual 
character varies a good deal, being more pronounced in some species, 
and ver}' feeble in others. Have you noticed the sex of the specimen 
of the new species ? " 

I was under the impression that the type is a female, as although 
the abdomen is conspicuously variegat<'d, the pubescent depressions 
common to so many males of the sub-family are entirely absent ; 
and in Rhytiphora I know of no other external feature by which the

ON A NEW KHYTH'IIOKA iN THE NATIONAL MUSEUM, MELBOURNE. 



sex of an unique specimen may be determined. Still, if cUiIlasi is 
without such depressions in the male, quite possibly the male oi this 
species is without them. 

At Mr. French's request, the species is named after the late Sir 
William Macleay. 








KhYTIPHORA MACLEAYI, SP. NOV. 

Black. Densely clothed with white and ochreous pubescence, in 
places glabrous or with black pubescence ; the el)i;ra conspicuously 
striped. 

ReaA large, with rather coarse but partly concealed punctures, 
with a narrow continuous median line. Antennse of moderate length. 
Protliorax about one-fourth wider than long, transversely rugose. 
Elytra widest across shoulders, sides thence regularly diminishing 
in width to apex, where each is acutely spined ; with four almost 
equidistant feeble but conspicuous elevations on each, the first very 
close to suture, the second terminated at about the apical fifth, the 
third commencing just within the shoulder, and the fourth just below 
it, these two conjoined near apex ; all these ridges have small granules 
towards the base, sometimes rounded, but often acute, and all have 
coarse punctures gradually decreasing in size posteriorly, but 
smaller on the subsutural ridge than the others ; the margin is 
narrowly ridged and smooth. Length 43, width 15 mm. 

Habitat. — Western Australia : Kook}Tiie. 

The clothing on the head is ochreous, but becomes whitish below 
the eyes and about the mouth ; on each side of the base near the 
middle there is a narrow black patch, straight on its inner, and 
curved on its outer edge. On the prothorax, the pubescence is 
whitish, but in places more or less deeply stained with ochreous, 
and leaving two curved black transverse lines, a median one not 
interrupted in middle, and a sub-basal one interrupted in middle. 
The scutellum has ochreous clothing, margined with black. On 
each elytron the stripes are as follow : — An extremely narrow pale

sutural stripe, a narrow black stripe, a wide silvery stripe, a narrow 
black stripe, terminated at the apical fifth, a wide silvery stripe, 
a narrow black stripe conjoined near tip with another on the outer 
edge of a wide ochreous stripe, a wide silvery stripe, and then the 
narrow black margin ; the white stripes about the base are more 
or less stained with ochreous. Under surface with silvery pubes- 
cence marked with ochreous stripes (one at apex of each abdominal 
segment) and blotches, and black patches (a longitudinal one 
towards each side of metasternum, and acur\-ed one — very narrow 
across middle — on each abdominal segment). Antennal jointft 
white tipped with black, but the black increasing till at the seventh 
it covers half the surface, and the eleventh is white at the extreme 
base only. The black patches and stripes are due either to the 
surface being bare or to being clothed with very short black 
pubescence.

ON AN UNNAMED SPECIES OF PECTEN FROM THE 
TERTIARY (BARWONIAN) OP SOUTHERN AUSTRALIA. 

By Frederick Chapman, A.L.S., F.R.M.S., Palceontologist to the 
National Museum, Melbourne. 

(Plate V.) 



A form of Pecten, somewhat closely related to Tate's Pecten 
consobrinus has long been known to Australian palaeontologists as 
P. consobrinus var. In Professor Tate's " A Revision of the Older 
Tertiary Mollusca of Australia,"* that author refers to P. consobrinus, 
var., as occurring at Aldinga Bay (Lower beds), Shelford, Maude and 
Belmont, Waurn Ponds, and Spring Creek. Messrs. Dennant and 
Kitson, in their " Catalogue of the Described Species of Fossils (except 
Brv'ozoa and Foraminifera) in the Cainozoic Fauna of A-'ictoria, 
South Australia, and Tasmania,"! cite the following localities for 
Pecten consobrinus var. Tate : — Aldinga (Lower beds). Aire Coast, 
Fishing Point and Guerard Hill, Shelford, Lower Moorabool, Maude, 
? Corio Bay, Curlewis-Belmont, ? Mitchell River, Waurn Ponds, 
and Spring Creek. 

It will thus be seen that this particular form is practically re- 
stricted to Janjukian beds, and possibly to the horizon immediately 
below, or the summit of the Balcombian series. 

The species P. consobrinus was originally described from the 
Upper beds at Aldinga ; whilst the variety occurs in the lower part 
of the same series, which is shown by its faunal characters, allowing 
for local lithologlcal differences, to belong to our Victorian Jan- 
jukian beds. 

The present note is written to establish a name for this variety of 
P. consobrinus, for the convenience of future reference. vSince it 
would appear illogical to refer to an ancestral form of an already 
described species as a variety thereof, it seems advisable to give it 
a specific standing, at the same time bearing in mind the fairly close 
relationship existing between it and the species from the yoimger 
beds. Its claims to a specific name are perhaps as great as are those 
of P. antiaustralis and P. australis. The affinity with P. consobrina 
is denoted by the denomination praecursor. 

Descriptioic of Type of Pecten praecursor, sp. xov. 
( = "P. consobrinus var." Tate). 

The type selected is a left valve of medium size (between the 
neanic and ephebic stages). 

Locality — Spring Creek, Torquay {ex Dennant Coll.)

ON AN UNNAMED SPECIES OF PECTEN. 



Description. — Valve triangularly orbicular, nearly eqiiilateral, 
the antero-ventral border more sharply curved than the posterior ; 
surface with ten maj<ir folds, subacute, with a summit ridge and 
generally two lateral ridges on either side ; interspaces occupied by 
from 2-6 costulse, the central usually stronger. All the riblets are 
closely lamellose or tegulate. Groimd surface finely granulate, 
with shagreen texture, tending tf) develop into transverse 
undulate ornament at the extremities of the valves. Ears very 
unequal ; anterior triangular, with (mtcr margin tnincated, having 
five radial costse ; interspaces granular ; posterior triangular, 
tnm(\ated ; faintly costate and granular. 

Measurements of type — Height, 25 mm. ; length, 24 n^m. 

Remarks. — This form differs from P. covsobrinus in having 
normally ten folds instead of eight. The folds are subacute, whereas 
in P. consnbrinus they are gently convex and equallj' and numerously 
costate. In P. praecursor, moreover, the transverse ornament of 
the riblets is, in fresh specimens, more decidedly tegulate, whereas 
in P. consobrinus the ornament is a series of delicate concentric 
frills. 

This species appears to pass upward into P. consobrinus (Kalim- 
nan) by loss of major folds, and to pass downward into P. foul- 
cheri ( Janjukian) and Balcombian by increase of folds and transition 
of tegulate ornament into the erect squamoee.

NOTES ON A COLLECTION OF TERTIARY LIMESTONES 
AND THEIR FOSSIL CONTENTS, FROM KING ISLAND. 

By Frederick Chapman, A.L.S., F.R.M.S., Palceontologist to the 
S'atinnal Museum, Melbaurne. 

(Plates VI., VII.) 



IXTRODUCTORY REMARKS. 

The samples of limestone and limestone-fossils herein described 
were collected by Mr. J. A. Kershaw, F.E.S., whilst on a recent 
exploring trip to King Island. Mr. Kershaw informs me that he 
found this limestone cropping out on the extreme south-east part 
of the island, and well exposed in the river bed and banks of 
the Seal River. The outcrop showed a vertical thickness of about 
25 feet. The limestone in places was vers' hard, and the horizontal 
bedding could be clearly seen on account of the weathering of the 
softer layers; the mum compact limestones projecting as ledges. 
The polyzoal rock with pectens was found outcropping at the sur- 
face of the upper levels. In the absence of any further note as to 
the relation uf the hard limestone to the polyzoal rock, it may be 
inferred that the latter overlies the hard limestone ; and, if this be 
the case, we have a similar sequence to that of the polyzoal rock of 
the Grange Bum, which is underlain by the hard pink limestone 
cropping out at the junction of Grange Bum and Muddy Creek. 

The present collection does not comprise many determinable 
fossils, but, nevertheless, is of great interest, for although several 
outcrops of tertiary limestone have already been reported from King 
Island,* no fossils seem to have been collected.! 

Prof. Baldwin Spencer, in his report on the general results of 
the expedition to that locality in 1887, J states that the limestone 
" lies directly upon the granite, and is widely distributed. Thus 
it was cut through (though the depth of the bed was not recorded) 
in laying the foundation for the Wickham lighthouse before the 
grey granite was reached. Again, an outcrop occurs half way from 
here to Yellow Rock, and on the east coast one a little south of 
Lavinia Point, and another at the BhjW-hole Creek. On the west 
it is well marked on the coast between the Pass and Ettrick Rivers, 
inland near Porky Lagoon, and again forms an extensive formation

on the surface inland from Fitzmaurice Bay." Mr. Kershaw's 
discovery of the same limestone series at the Seal River is therefore 
additional to the previous records. 

During a recent expedition Mr. E. B. Nicholls obtained specimens 
of a limestone of similar age to the above, and largely composed of 
polyzoa, which he collected on the east coast, 8 or 9 miles south 
of Sea Elephant River. This also is a new locality. The specimens 
have been presented by Mr. Nicholls to the Museum. 

General Description. 

One variety of the limestone from the Seal River is of a pale 
ochreous colour, fragmental in structure and of a friable nature. 
Hand specimens of this rock are seen to consist chiefly of polvzoa 
with occasional shells of pectens and other mollusca. It bears a 
strong resemblance to certain beds of polyzoal rock at Waum 
Ponds, Batesford, and Torquay. 

A harder limestone, associated with the" polyzoal rock, is yellow 
to pink in colour, close textured, and occasionally cavernous, with 
a tendency to the development of crystalline calcite in the hollows. 
This rock, like the former, contains much polyzoa and numero\is 
echinoid spines. In its hard texture and pink colour it is closely 
comparable with the compact limestone of the beds occurring in 
association with the older basalt on the banks of the Moorabool 
River, near Maude (W.T.M. 2 and 4 in Nat. Mus. CoU.). 

A microscopical examination of thin sections of the friable 
limestone (PI. VII., fig, 5) shows the same organic constituents as 
the compact rock, with the exception that the former has a liberal 
proportion of clear calcitic cement between the indi\adual grains, 
whilst the hard limestone has a cement of the nature of a dense 
pinkish-brown calcareous mud (PI. YLI., fig. 6).

PaLAEACHLYA TUBEROSA, SP. NOV. 

(Plate VII., Fig. 4.) 

Some of the shell fragments in the pink limestone were seen 
to be perforated by a parasitic boring organism. Remains of this 
kind are frequently met with in both recent and fossil shells and 
corals, as well as in fish-scales, teeth, and bones. Certain of these 
are referred to algae, whilst others are regarded as fungi, j It is 
probable that the form herein dealt with is of the nature of a fimgus, 
since the thallus is merely constricted and not distinctly septate, 
and has sporangium-Uke terminations.

NOTES ON A COLLECnON OF TERTIARY LIMEST )NES. 

Description of the borings of P. tuberosa. — Found in shell frag- 
ments which ;iro penenlly more or less wat«r-worn. Perf(jrations 
(A type), at first slender, entering the shell at right angles to the 
shell surface or nearly so,* subsequently bec<miing slightly tortuous, 
and tending to give off short branches, gradually increasing in 
width until terminated by a bliuit or swollen end ; cohmr, amber 
yellow. Other perforations in association (B type), commencing as 
an extremely fine short tube, wliich suddenly develops a more or 
less globular termination (? sporangium). Colour, deep reddish 
brown. Tubes and terminal swellings usually more or less filled 
with granular material, probably of the nature of spores, some of 
which are also seen scattered in the neighbourhood of the (?) sporan- 
gium. As mentioned above, no distinct septation of the vegetative 
structure visible, but occasional constrictions occur through the 
course of the tube. Tlie borings average 13 micra in diameter, 
and 86 micra in length ; sub-globose terminations averaging 18 
micra in diameter. 

Obsermtio7is. — The shortness of the perforations and their charac- 
teristic clavatc terminals serve to distinguish the present form 
from Dimcan's Palaeachhjn ferforans,'\ which that author foimd 
ver>- widely distributed in geological time; one example described 
having occurred in a foraminifer of Ordo\'ician age.J 

MM. Bomet and Flahault§ have described a boring organism, 
Lithopythium, which they refer to the iungi. Their species, L. 
queketti, bears certain resemblances to the above form ; it has a 
tortuous and filamentous thallus, with globular sporangia at the 
terminations and outer angles of the sinuses. It differs, however, 
in the closely interlacing habit of the thallus and the perfectly 
globular sporangia. 

M'ith regard to Australian occurrences of Pcdaeachlya, Mr. R. 
Etheridge, jim., has described P. tortuosa as a parasitic species 
within a Queensland monticulipf>rid oi Carbo-permian age.|| The 
chief characters of that species are, a flexuous tube, circular in 
section, with the terminations irregularly enlarged and with (»c- 
casional swellings along the course of the tube. Another species 
instituted by Etheridge is P. torquis,'[\ foxmd in the coeuost«um of 
a species of Favosites from the Devonian limestone of Tamworth, 
New South Wales. This form consists of slender contorted tubes, 
filled with yellow granular matter, and haNdng a diameter of "01 mm. 
It will be seen that the tube of this species is comparable in size to

the above-described form, but which differs, in the very limited 
length of the tubes, their swollen ends, and occasional bifurcati(m. 
It is worthy of notice that Professor Duncan, in his paper previouiily 
referred to, figures some very diverse forms imdcr his diagnosis of 
Palaeachlya perforans, and that one oi his examples, from a Tas- 
manian Tertiary coral (Thamnastraea) is distinct from our species in 
that the tubes are excessively slender, long, and tortuous.* P. 
tuberosa also occurs in shell fragments in the limestone of the 
Moorabool Valley at Maude.

LiTHOTHAMNIUM SP. 

Minute fragments of this calcareous alga were seen in thin sections 
of both limestones, but were too imperfect to compare with any 
Tertiary examples already described. They belong to a ramose 
form, since a terminal fragment was observed, showing the charac- 
teristic curved and divergent series of cells. The cells from a well- 
developed branchlet showed a height of '034 mm. and a width of 
•019 mm.

A nearly median section of a Globigerina shell occurs in a thin 
slice of the hard pink limestone. Its test is moderately thick, and 
from the regular helicoid form, it appears to be referable to G. bullmdes. 
This species has been recorded by Mr. Howchin from the Muddy 
Creek (lower) beds (Balcombian), Waum Ponds (Janjukian), and 
Moimt Gambler (Barwonian).

A good example of T. variabilis is seen in a thin section of the 
pink limestone from the Seal River. It is easily recognised by its 
thin test and numerous chambers arranged in a tortuous and broken- 
spiral fashion. 

From the Australian Tertiaries, Mr. Howchin obtained this 
species in the older beds of Muddy Creek.

In the present series there are two calcareous joints of an 
alcyonarian which may be referred to the above species. One of 
them is more or less cylindrical (subquadrate), and longitudinally 
grooved with comparatively coarse and deep furrows. Ridges 
often once bifurcated and slightly twisted. A few impressed puncta 
visible along the surface of the ridges and sometimes in the furrow*. 
A scar on the side of this specimen seems to indicate the position 
of a branchlet. P]nd of axis dilated and meeting the intemodal 
surface to form a tolerably sharp angle. Terminal face subconical, 
furrowed, and subdivided into a series of primar}' septa, and by 
further division into as many again. These furrows are generally 
continuous with those on the lateral surface. There is a small 
conical papilla in the centre of the articular surface. Diameter of 
axis, 2 '5 mm. 

The second specimen is much shorter, slightly stouter, and with 
the lateral furrows crossed by little bars or dissepiments, giving 
the grooves a distinctly punctate appearance.

There is no doubt of the relationship of the tw(j specimens 
figured, since all the chief characters are common to both. 

Observations. — Mopsea hamiltoni has been lately described by Jlr. 
J. A. Thomson, from the greensands accompanying the limestones 
at Kakanui, New Zealand. Mr. Thomson remarks on the apparent 
identity of Duncan's New Zealand example, Isis sp.*, with the t}'pe 
above referred to, and the writer had come to the same conclusion 
regarding these, and also the Cape Otway sj)ecimens figured by 
Dimcan,t prior to seeing Mr. Hamilton's paper. The fossils, how- 
ever, belong to the genus Mopsea and not to Isis, as wiU be seen on 
comparing, the structure of the joints with those of the species of 
Mopsea still found living round the Australian coast. Duncan's 
remarks upon the affinities of the fossils did not clear the ground 
for later students, for, in following Ehrenberg, he says, "It is this 
branching from the calcareous body which distinguishes the genus 
Isis from Mopsea, in which the branching starts from the homy 
substance {loc. cit., p. 673). In point of fact, the typical Mopsea 
encrinula, to which our species is allied, shows the branching to 
take place on the calcareous internodes by the formation of a horny 
node, in some cases, however, so close to the node as to appear to 
start from it, when in reality it is attached to the calcareous joint 
(see also Wright and Studer, Chall. Rep. on Alcyonaria, p. 40). 

The above species is distinct from Tenison Woods' Isis ductyla,% 
in having finer lateral striations a^d concentrically lineate condyles. 
Isis melitensis of Goldfuss,§ is more nearly relat'«i to /. dactijla in 
having fine and numerous lateral furrows ; whilst the internodal 
faces are acutely conoidal and devoid of radial grooves. Goldfuss' 
species was found in the Pliocene of Sicily and Piedmont. 

The above species was found in the polyzoal rock of the Seal 
River outcrop.

There is a somewhat worn fragment of the test of a cidarid in 
the present series. It shows a portion of the interambidacral area 
with two primary tubercles and a line of ambulacral pores. Only 
the one species above mentioned has been recorded from our Ter- 
tiaries, and the present specimen, so far as the fragment shows, is 
probably referable to it. It was first described from the Cape

Otway beds (Janjukian). It also occurs in the Lower Aldingan 
beds, and the higher zones of the Balcoinbian, as at Bairnsdale, and 
has also been recorded from Beaumaris (Kalimnan). 
Found in the polyzoal rock. 

Spines of Echinoids. 

(Plate VII., Fig. 5 a.) 

Several varieties of echinoid spines are met with in thin sections 
of the polyzoal rock. In their asperous surface and average dimensions 
they resemble the smaller secondary spines of the Cidaris type.

Tw^o of the valves of pectens have attached to their external 
surface some remains of annelid tubes referable to Spirorhis. The 
tubes are not sufficiently well-preser\-ed for description. The 
superior face is convex and subconical. excavate centrally and the 
surface of the tube transversely wrinkled, whilst a median ridge 
runs along the upper surface bordered by two lateral ridges. The 
tube varies somewhat in diameter, averaging about 1 "25 mm. 

The genus is mentioned by Tate* as occurring in our older Ter- 
tiary beds. The above specimens occur in the polyzoal rock. 

POLYZOA Cyclostomata.

(Plate VI., Figs. 5, 6.) 

H. fisiformiis, MacGillivray, 1895, Trans. R. Soc, Vict., p. 144, 
pi. xxi., fig. 15. 

The definition of this species, which Dr. T. S. Hall furnished for 
the late Dr. MactHllivray's report, runs as follows : — "' Zooecium 
nearly spherical, apparently free. Surface closely covered by rounded 
polygonal apertures of varying size, so that it is not evident in many 
cases which arc zooecia and which are ca«celli, as all gradations 
in size are present. Bounding walls of aperture stout. The aper- 
tures of all sizes usually closed by a concave porous plate placed 
slightly within the mouth." 

Three examples were found in cnishings from the polyzoal 
limestone of the Seal River. One w;us perfectly spherical, and 
subsequently fell to pieces owing to incipient fracture. The zoarium 
here figured is spherically topped, but appears to be adherent to a 
foreign particle at the base, so that it has assumed the shape of a 
fig. The third specimen was partly damaged, but still shows a 
clavate outline, and of this a section was made, which exhibits the 
curvi-radiate arrangement of the zooecia. 

This species lias hitherto been recorded only from Spring Creek, 
Torquay (Janjukian).

S. marginata, T. Woods, 1880, Trans. R. Soc, S.A., Vol. III.,

The Zoaria are abundant in the hard pink limestone. In thin 
sections of the rock they are cut in all possible directions, and show 
the characteristic form of the thyrostome. Where the sections cut 
through the apex, there is usually seen an adventitious shell or 
detrital fragment immersed in the apical portion. The zooecial 
margins are rounded, and there are numerous \4bracular cells inter- 
spaced at the angles of the zooecia, of about half theirsize, and with 
a cribriform wall. A section parallel with and close to the dorsal 
side shows the radial areolae to be non-porous, as in MacGillivray's 
var. lucens*

S. concinna, T. Woods, 1880, Trans. R. Soc, S.A., Vol. III.,

Sections of the entire zoarium occur in the hard pink limestone. 
They show the characteristic shield-shaped outline of the zooecium, 
whilst the apical zooecia have in some cases the projecting tongue 
on the proximal border, which is feebly developed in this species 
and more strongly shown in the allied S. otwayensis, Maplestone.f 
The elongate vibracularia cells can also be made out, more than 
one showing the opening with the serrate border typical of this species. 

Tenison Woods recorded this form from the Kalimnan of 
Muddy Creek. It is also distributed in the lower beds, of 
Barwonian age, in Victoria (Maplestone).

Lepralia crassatina, MacGillivray, 1895, Trans. R. Soc, Vict., 
Vol. IV., p. 74, pi. viii., fig. 4. 

Our example is represented by a small cluster of encrusting 
25ooecia. somewhat inflated, with sub-he.\agonal margins. In its 
general character it agrees with the above species, with the excep- 
tion that many of the zooecia tend to become sub-elliptical by 
crowding. It has the porous front wall to the zooecium and semi- 
circular thyrostome as in the above form. Mr. Maplestone has 
pointed out to me that MacGillivray's species appears to belong 
more properly to Macropora than to Lepralia. A comparison 
may be made with Macropora darkei, T. Woods sp.* That 
species, however, has a generally depressed or even concave zooecial 
wall, and the zooecia are distinctly broader than in our form. 
(?) L. crassatina occurs throughout our Tertiary series, being foimd 
in the lower beds of the Muddy Creek series, at the Moorabool River 
and Waurn Ponds; and is also found living off New Zealand. 

Found attached to a valve of Placummomia in the polyzoal rock 
of the Seal River.

A portion of the branched stem which supports the flabellate 
zoarium occurs on the surface of one of the slabs of polyzoal lime- 
stone. It measures 40 mm. in length and 27 mm. across at the 
widest part, where there are nine branches. 

BRACHIOPODA. 

M.A^GELLANIA cf. DIVARICATA, Tate sp. 

A cast of a brachiopod shell occurs in the hard pink limestone, 
which is referable to one or other of the closely related species M. 
divaricata, Tate sp.f or M. garibaldiana, Davidson sp.J The 
radial plication seen in the present example is common to both species, 
but the shell of M. divaricata is typically narrower, and shows a

transversely truncated, forming a right angle with the dorsal margin. 
Dorsal line slightly concave. Umbo convex and incurved to the

crossed at fairly regular intervals by transverse flat ridges. Ventral 
slope marked by numerous incurved ridge-like growth lines. 

Length (approximate, minus the extreme point of the umbo), 
15 "5 mm. ; greatest width, 7 mm. 

Observations. — This is a small species of Pinna which, in its 
strong convexity, narrow umbonal area, and the general outline 
resembles P. cordata, Pritchard*, with the exception that our shell 
is of a more oblong form. P. reticosa is distinct in having the dorsal 
ribs transversely cancellated by flat ridges parallel with the growth 
lines. The above form differs from P. semicostata, Tate,t in the 
relative narrowness of the proximal part of the^hell, and the absence 
of scales on the ribs. Professor Tate has also recorded a species 
of Pinna (sp. indet.) from the Calciferous sandrock, River Murray 
cliffs, near Morgan, which agrees generally with the above-named 
species P. reticosa, and he gives the following description! : — 
" Apical portions only known. Valves acutely angulated, with 
faint longitudinal ribs separated by broad interspaces on the 
ventral slope, crossed by undulose ridges."

Two typical valves of tl^is species are found in the present series. 
The larger specimen shows, towards the front margin, some distant, 
concentric lamellae traversing the ribs, a character mentioned by 
Tate in his original description of the species. 

It is interesting to find the above species in the present series, 
since, with the exception of Stansbury, S.A., Tate's original record

South Australia, in glauconitic limestone (Lower Aldingan).

Perhaps the most abimdant fossil remains in the Seal River 
polyzoal rock, \vith the exception of the polyzoa, are those of 
Pecten. Of this genus the species P. aldingensis is readily recog- 
nised, but the remaining specimens show a considerable diversity 
of ornament, partly due to the condition of the shells, so that it was 
somewhat difficult to settle their points of relationsliip. There 
are, however, several fairly weU-proser\'ed fragments which show 
that P. praecursor is present, and was an abundant form. One of 
the more perfect valves represented in the present series is nearly 
flat, and by the curvature of the ribs is seen to be a left valve. There 
are about ten or eleven primary folds with a strong median rib, on 
either side of which are one or two secondary ribs, and between 
these numerous riblets. Another specimen shows a part of the 
ventral margin of the valve, in which the surface ornament is par- 
ticularly w-ell-preser\'ed. The surface of the ribs is concentrically 
relieved by a series of imbricating lameUse similar to that seen on 
well-preserved examples of P. antiauslralis.* The paucity of the 
ribs precludes any reference to that species, and, moreover, the 
intercostal spaces in our specimen are distinctly of a granular shagreen 
character. 

P. praecursor is a characteristic fossil of the lower beds at Aldinga, 
as well as of many localities, chiefly (or all ?) Janjukian, in Victoria.

The latter, according to Professor Tate's synopsis of characters, is 
distinguished by the fine radial threads, as compared with the coarse 
ornament of P. ione, whilst in the latter the radii tend to become sub- 
spinose. It is just possible that one of our specimens may belong 
rather to P. ione, since it measures 46 mm. in height ; that of Tate's

Note on the Aoe of the Beds. 

The palseontological e\'idence of the foregoing limestone fossils 
strongly supports the idea of their Janjukian age. Therefore, 
from a physiographic stand-j^oint, the King Island limestone beds 
were presumably continuous with those portions of the old sea-bed 
now represented by the Bird Rock Cliffs, the fossiliferous shell-beds 
of Table Cape, Tasmania, and the lower beds at Aldinga, South 
Australia. Not the least interesting fact brouglit out by the present 
examination of the King Island fossils is the occurrence in this fauna 
of two species of mollusca which have hitherto been known almost 
exclusively from the lower Aldinga beds of South Australia, thus show- 
ing a strong affinity in its facies with the f<jssils of that area. 
Although the present list of fossils is not so extensive for a complete 
comparison with other southem Australian horizons as could bedesired, 
yet the evidence before us is fairly conclusive, since the already- 
known forms recorded here have all — excepting one doubtful poly- 
zoan, which, however, is found living — been previously found in 
either the Table Cape beds, the Spring Creek series, or the lower 
Aldingan strata. Further than this, some are peculiar to the 
Janjukian group. 

The correlation of the lower Aldingan beds xvith normal Jan- 
jukian strata is by no means new, since this relationship was long 
ago pointed out by Messrs. Tate and Dennant* in dealing with the 
Cape Otway series, also Janjukian. Those authors, however, in- 
cluded both the upper and lower beds at Aldinga which, as Messrs. 
Hall and Pritchard rightly point out,f belong to distinct stages. 
The first-named authors, in their second paper on the " Correlation 
of the Marine Tertiaries of Australia," noted {loc. cit.) "the com- 
paratively large proportion of Aldingan species " in the Cape Otway 
section. " Thus of the forty Aldinga species present at Cape Otway, 
eighteen are restricted to these two sets of beds," "whilst five of 
the species indicated are common also to the Spring Creek Fauna." 

In my examination of this collection I am xmder obligations to 
Dr. G. B. Pritchard, F.G.S., and Mr. C. M. Maplestone for helpful 
suggestions regarding the mollusca and polyzoa respectively.

NOTE ON FIJIAN CLUBS ORNAMENTED WITH 
MAORI PATTERNS. 

By R. H. Walcott, F.G.S., Curator of the Geological and 
Ethnological Collections. 

(Plate VIII.) 



During a visit to the Museum, Professor R. B. Dixon, of the 
Anthropological Department of the Harvard University, was par- 
ticularly interested in a Fijian club bearing an incised design of 
distinctly Maori origin. Professor Dixon had pre\nously seen 
elsewhere two other specimens ornamented with a similar type of 
design, and as, apparently, no record had been made of such an 
interesting instance of borrowed art, it is well that the Museum 
should publish a description of the specimen in its collection. 

I was fortvmate enough, on mentioning the subject to Mr. W. H. 
Schmidt, of the Australian Metal Company, Melbourne, to find 
that he had in his private collection another example of a club 
decorated in a similar manner, which he kindly offered to lend for 
description. 

The Museum specimen, Reg. No. 14,870 (Fig. 1), is, apart from 
its ornamentation, an ordinary Fijian club of the cylindrical 
type. Its total length is 3 feet 7f inches, with an approximate 
diameter of If inches for 23 inches of its length from the 
end of the handle. It then gradually increases in diameter to the 
termination of the head, where it attains a maximum of 1| inches. 

The end of the handle is hollowed out to a depth of a quarter 
of an inch, a feature not uncommon in Fijian clubs. 

The incised design on the handle extends from the extreme 
end for 11| inches without a break, and from its termination to the 
end of the head, seven bands, about three-quarters of an inch wide, 
of the same incised design are unequally spaced. 

The specimen was acquired from Mr. W. Simmonds, of Melbourne, 
in March, 1908, by whom I have been informed that it was collected 
by himself some thirty or more years before. Mr. Simmonds, who 
made a number of visits to Fiji, was unfortunately unable to recollect 
imder what circumstances he obtained the club, or from which 
island of the group. 

The style of ornamentation is common in Maori carvings, and 
consists, as may be seen from Fig. 2, which is a reproduction of 
a rubbing, of a series of transverse parallel bands each of four 
lines, alternating with single lines of diamond-shaped points. The 
bands of parallel lines do not continue unbroken round the whole

NOTE ON FIJIAN CLUBS. 



circumference of the club, but at some place or places in their length 
bend sharply either upwards or downwards to meet the adjacent 
band. Interspersed among these are six link-Uke ornaments, five 
resembling the stud links of a ship's cable, and tiie sixth resembling 
two long plain links. They are arranged longitudinally with 
reference to the greater axis of the club, or at right angles to the 
main design, which they resemble in principle, but they are com- 
posed of three lines instead of four, as in the transverse bands of 
the main design. 

It seems evident that this type of ornamentation is derived from 
the spiral, so characteristic of Maori art, and only resembled at all by 
the scroll pattern prevalent in New Guinea decoration. 

Mr. A. Hamilton,* Director of the Dominion Museum, Wel- 
lington, N.Z., was informed by an old Maori that the spiral, 
called pitau, represented the young circinate frond of the tree 
fern, pitau being the Maori term applied to the young frond of 
the tree fern (Cyaihea). 

The small studs between the coils of the spiral in the carvings 
represent the pinna? of the frond. The five links in the design 
on the club are plainly only the elongated first or central coil of 
the spiral, with one end continued and closed on the central coil, 
while in the double links both ends are continued and closed. 

The transverse bands are simply a further elongation of the 
same coil, although their origin is not so apparent. The diamond- 
shaped points forming lines between the bands and in the links take 
the place of the studs in the spiral. 

Mr. Schmidt's specimen (Fig. 3), which has no available history, 
he having purchased it from a dealer in Prahran, a suburb of 
Melbourne, is what is commonly knowTi as the pineapple type 
among Fijian clubs, on account of the head bearing a resemblance 
to that fruit. 

As in the previous specimen, there is also nothing in the form 
of this club which shows any departure from the tj-pe it represents. 

The ornamentation (Fig. 4) is restricted to 8^ inches of the 
handle, the rest being perfectly plain. With the exception of a 
central transverse band, the ornamentation is in the main similar 
to that just described. 

These minor differences consist in most of the four lined bands 
being curv'ed, and not bent to meet the adjacent ones. The dis- 
tance between the bands is also greater, so that the diamond-shaped 
points of the other club here rather assume the character of short 
longitudinal ridges, and in the two lower links they are replaced 
by U-shaped forms. The links, of which there are four, are all 
double, while in the Museum specimen, as pointed out, there is only 
one of this kind. 

• Maori Art, Part I., p. 11, 1896. 
[55] 



NOTE ON FIJIAN CLUBS. 



The transverse band near the centre of the design, referred to 
above (Fig. 4), is about three-quarters of an inch wide, and consists 
of a trianguhir jiattern of closely placed lines. The .style of this 
decorative band .seems to be more characteristic of Fijian than of 
New Zealand ornamentation. 

With regard to the origin of Maori ornamentation on Fijian 
articles, it is a matter of some difficulty to decide to what circum- 
stances it is due. 

Accepting the theory that Maori art is endemic, it having been 
evolved since the isolation of the Maoris from the rest of the world 
after the last great migration about the year 135U, and was not brought 
with them from their original home, it cannot be said that that 
found in Fiji represents the remnant of a type originally derived 
from a common source and distributed throughout many islands 
in the Pacific visited and colonized by the early Polynesians. 

No intercourse, then, having taken place between the Maoris 
and other peoples of the Pacific since the evolution of their art, 
its introduction into Fiji can best be explained by attributing it to 
communication between the two places, which commenced with 
the European whaler.s and traders at the beginning of last century. 

There is, however, a possible explanation which may refer its 
introduction into Fiji to earlier times, and which was suggested by 
pieces of a New Guinea canoe in the Museum, said to have been 
picked up on the coast of New Zealand. It is that, in like manner, 
a Maori canoe may have been driven out of its course and eventually 
stranded on one of the islands of the Fijian Group, where either the 
designs on the canoe were copied by the inhabitants, or the charac- 
teristic form of carved decoration was made known to them by 
some of its Maori survivors. 

If by this explanation its origin can be referred to a period ante- 
dating the advent of the European, the fact may possibly be ascer- 
tained by the type of weapon, or some feature in the carving, 
differing from that of more modern times. There is nothing in the 
types represented by the two clubs under consideration, or in their 
condition, to suggest antiquity; and with reference to their orna- 
mentation, I am not in a position to give an opinion as to any 
variation in the detail of the work which may offer a clue; but I 
believe Professor Dixon held the view that some such evidence 
of antiquity did exist in the Museum specimen. On the other hand, 
it may only mean that the ornamentation, used originally as a 
pattern, was of ancient design. 

Failing proof of antiquity, it appears to me that the ornamenta- 
tion most probably originated either by articles brought from New 
Zealand to Fiji by missionaries, traders, or whalers, or else by some 
of their Maori sailors decorating the weapons of the Fijians with the 
New Zealand patterns. 

[56 J 



NOTE ON FIJIAN CLUBS. 



In this way the Maori type of ornamentation may have become 
kiiuwTi to the Fijians, and, perliap.s, adopted by them at times, as 
offering a pleasing variation on their own well-known designs; but 
it is not even certain that its introduction can be put back as far 
as is suggested, and it may only date from about forty or fifty 
years ago, when a rapid influx into Fiji from the Australasian 
Colonies took place.

Previous Opinions of Time Equivalents. 

In the earlier davs of paheontolonrical work in Victoria, the 
conclusions as to the age of the rich Tertiary faunas of southern 
Au.stralia* were nece.s.sarily founded on Hniited evidence, derived 
from an imperfectly-known .series of fossils. The paltcontology of 
these beds had then been scarcely touched by .systematic workers, 
so that the .small number of species available for purposes of com- 
pari.son. both in relation to the question of local stratigraphical 
.sequence and the wider one of correhiting them with the well-studied 
Tertiary faunas of Europe, rendered a solution of the problem one 
of great difficulty. 

The first effort at correlation was made by Sir A. R. C. Selwyn in 
18.')4, who. in a "Report on the (leology, Pakcontology, and 
Mineralogy of the Oountrv situated between Melbourne, Western 
Port Bay, Cape Schanck, and Point Xepean,"t stated, "Both the 
clay and limestone " [of the Mornington beds = Balcombian] "are 
very rich in fossil remaias, and both in general lithological character,

mineral and organic contents, bear a striking resemblance to the 
clay and associated calcareous nodules of the London and Hampshire 
Basins." Since no detailed analysis or comparison of the fossil 
faunas were offered, this conclusion was only tentative. A further 
opinion was advanced by Selwyn in 1856, when, in his " Report 
on the Geological Structure of the Colony of Victoria, the Basin of 
the Yarra, and part of the Northern, North-eastern, and Eastern 
Drainage of Western Port Bay,"* he relegated the Victorian 
Tertiaries to Eocene, Miocene, Pliocene, and Pleistocene. 

"William Blandowski, in 1857 (in a Report A^Titten in 1854)j 
referred to several genera of mollusca and polyzoa as occurring in 
the Mount Martha beds (= Balcombian), and expressed the opinion 
that they are co-eval ^\"ith the uppermost strata of the London, 
Paris, and various Italian clay basins. 

The Mount Gambler Cainozoics (polyzoal limestone) were regarded 
by the Rev. J. E. Tenison Woods, in 1859, t as Eocene ; but, later, 
of the age of the Pliocene Coralline Crag in England.§ The same 
author finally arrived at a mean in concluding!! that they were older 
than that series, and younger than the Muddy Creek beds ; con- 
clusions which are upheld in the present paper, as far as relate to 
the lower bed of that series. 

Sir F. McCoy, in 1861,^ regarded the Balcombian beds of Mt. 
Ehza and Mt. Martha (Balcombe's Bay) as of Upper Eocene age ; 
but this was subsequently altered** to Oligocene, in accordance with 
the change of nomenclature and subdivision of similar beds in 
Europe, to which McCoy referred in the following terms : — '" These 
have the general facies, and even specific identity of so many species, 
so clearly marked that there cannot be the shghtest doubt of the 
great thickness of those beds being Lower Miocene of the date and 
general character of the Faluns of Touraine, the Bordeaux and the 
Malta beds ; while the base of the series blends imperceptibly with 
a series of beds having a slightly older facies, and rendering the 
adoption of the Oligocene formation of Be}T.'ich as convenient for 
Victoria as for European geologists." In this Essay McCoy draws 
the inference of a community of strata of Oligocene and IMiocene 
a'ges exhibited in the Victorian, European, and North American 
deposits, by noting the occurrence of the teeth of Squalodon jt and 
typical IMiddle Tertiary sharks. With his extensive knowledge of 
European fossil faunas, and a keen eye for resemblances in the facies 
of widely separated areas, ]\IcCoy gave his conclusions, which were at

the time almost prophetic, but in reality were based on a knowledge 
of the guide fossils of both areas. It had yet to be proved whether 
the Lyellian method of molluscan percentages as a test of the exact 
age (or as in the case of antipodeal strata, of their homotaxial 
relationships) could be applied to the Cainozoic beds of this southern 
continent. 

A suggestive contribution bearing on the present subject is found 
in the Rev. J. E. Tenison Woods' " False ontological Evidence of 
Australian Tertiary Formations."* In this paper the author 
showed that a close relationship exists between the majoiity of our 
Tertiary fossils and those of the Miocene of other areas ; and although 
many of the fossil determinations given in that paper require some 
revision, the conclusions are based on good reasoning. He there 
says,t " Speaking of the Corals generally, we have more affinities 
with IMiocene forms than any other formation ; but a few genera 
are common to both Eocene and Miocene formations. We have 
no truly Eocene forms, such as Turbinolia, which are found in the 
Eocene" beds both of Europe and America ; neither have we among 
the many Foraminifera such characteristic fossils as Xummulites ; 
but we have certain American genera which have seldom been found, 
as far as I am aware, above the Eocene." With regard to his remark 
about the absence of Nummulites in Australia, Tenison Woods was 
the first to record our commonest nummulinoid form as Amphis-

Subsequently the genus Nummulites was recorded from our Cainozoics 
in error for Am-phistegina, as will be shown in a separate section, 
and this has been a factor in the acceptance of the Eocene age of the 
Lower Muddy Creek and other related beds by certain authors. 

The corals and echinoids of Victoria were first systematically 
dealt with by Prof. M. Duncan,§ and yielded that author no very 
decided evidence as to the age of our Cainozoic fossil series, when 
compared with the European faunas ; although Duncan remarked] | 
that the southern Australian fossil deposits with madreporaria, 
polyzoa, echinodermata, and moUusca have " a facies characteristic 
of all the European marine tertiary deposits above the Nummulitic." 
Later on he stated^ that the aspect of certain genera of the echinoids 
" gives a Nummulitic-of-Europe-and-India facies to the fauna, whilst 
the cretaceous aspect is presented by Catopygus ..." also noting 
other genera the names of which, as well as of the supposed 
Catopygus of Southern Austraha (now Studeria), have since been 
changed, redeterminations showing that the forms have a Tertiary

relationship. At the same time he admitted that many of the .species 
were abnost identical with those of the Miocene of ^lalta. Duncan 
was inclined to group the Australian tertiaries in one series as 
Cainozoic, referring the deposits below the Mt. Gambler beds to the 
Lower Cainozoic, and all above it to the Upper T'ainozoic.* 

By the researches of Prof. Jlalph Tate, Sir F. McCoy, and others, 
who have so ably followed in descriptive work, a large number of 
Tertiary species, particularly in the group of the niollusca, have been 
carefully diagnosed and figured ; although in some cases perhaps 
scarcely enough attention has been paid to the work of authors 
who have dealt with fossils from related strata in areas not verv 
far removed, as those of New Zealand. A critical examination of 
our Victorian lists will in all probability show that in more than one 
instance the same fossil is credited mth two names. On the other 
hand, this comparative work has been often retarded by iasufhcient 
descriptions and inadequate illustrations. 

A modification of ]McCoy's earlier opinion of the age of the 
Victorian strata was published in the First Progress Report of the 
Geological Survey of Victoria in 1874 (pp. 35, 36), in which there 
occurs a list of fossils by that author, correctly placing the Mornington 
beds at the base of the series, and referring to them as Oligocene. 
In this Hst, however, there is an admixture of fossils which are now 
referred to two different horizons in Victoria.! 

In the correlation of the southern Australian Tertiaries by Prof. 
Ralph Tate and Mr. J. Dennant, in 1893, J the clays and polyzoal 
Umestones of the Balcombian and Janjukian Series (giving them 
the local terms applied by Drs. Hall and Pritchard, vide seq.) are 
there referred to the Eocene. The Cainozoic strata of the Gippsland 
Lakes and the upper bed at Muddy Creek (^ Kalimnan) are there 
called Miocene. The older and newer mammaliferous drifts are 
regarded as Pliocene to Pleistocene. 

In 1895 Dr. P. H. MacGillivray, fresh from the study of our 
Cainozoic polyzoa, makes the following statement : — " The age of 
•the deposits has been the subject of a good deal of discussion among 
geologists. They are now generally referred to the Oligocene or 
early Miocene, but some are considered by different authorities to 
belong to the Eocene. It is difficult, however, to believe that any 
of them can be so old as the Eocene, at least considering it to be 
comparable to that of Europe. So far as an opinion can be formed 
from an examination of the Polyzoa, they are not of very different 
ages."§

follow Messrs. Tate and Dennant in the same general reference of the 
older Cainozoics to the Eocene, but consider the Janjukian beds 
{vide posted), in contradistinction to the last-named authors, to underlie 
the Balcombian clays. This difference of opinion as to sequence 
is mainly due to the occurrence of fossiliferous clays resting on the 
polyzoal rock at Belmont* and Curlewis containing a fauna which 
was compared by Hall and Pritchard with the Balcombian clays 
of the Mornington and Muddy Creek type. The difficulty is easily 
explained by the fact that the species in these upper clays are 
unrestricted ; that is, they pass from the underlying Balcombian 
into the Janjukian, but are, to a great extent, absent from the 
intermediate polyzoal facies, purely on account of difference of 
hydrographical conditions. 

Until Drs. Hall and Pritchard instituted local names for those 
beds showing distinct faunal characters, f references to the various 
strata were very confusing, since no two authorities were actually 
agreed as to the use of the terms Eocene, Oligocene, jMiocene and 
Pliocene when applied to the southern Australian CainozoicJ The 
local names referred to are Balcombian, Janjucian (afterwards 
phonetically spelt Janjukian), Ivalimnan, and Werrikooian. To these 
terms were afterwards added the comprehensive term '" Barwonian," 
which includes both the Balcombian and Janjukian, as having some 
faunal characters in common, and distinguished from the Kalimnan, 
between which and the Balcombian there seemed, to the 
above authors, to be a greater palseontological break. It is here 
postulated that the Janjukian is the younger series, and therefore 
nearer in faunal characters to the Kalimnan ; and, moreover, 
the palseontological difference referred to is not so marked 
as those authors believed. This is borne out by an exhaustive 
study of the fossils of the Mallee borings, in which there occurs 
a gradual passage downwards from Kalimnan into Janjukian, 
without intercalation of beds containing restricted Balcombian 
fossils. 

In Drs. Hall and Pritchard's important paper on "A Suggested 
Nomenclature for the Marine Tertiary Deposits of Southern 
Australia, "§ those authors give a convenient summary of the various 
opinions as to the sequence and age of our Cainozoic strata, together 
with their local terms for these beds, which has already proved to 
be of the greatest use in providing a definite terminology for the 
various outcrops. The use of local terms consequently prevents 
that confusion which previously occurred when each author ascribed

In Drs. Hall and Pritchard's paper above referred to, the 
sequence given for the Australian Tertiary strata places the Janjukian 
at the base of the series. There is very strong evidence, however, 
in favour of the Balcombian being the oldest formation with marine 
fossils, and of an approximately equivalent age to the Upper 
Oligocene and Lower Miocene of Eurojje, North America, the West 
Indies, and Patagonia. In connexion with the last-named area, 
Ortmann* lately published an elaborate account of the fossils, and 
gave his conclusions as to the age of those beds. He also compared 
them with the Australian Tertiaries, agreeing almost entirely mth 
the early views of McCoy. Dr. Ortmann based his conclusions upon 
a comparison of the fossil invertebrates with related forms from 
other localities and horizons in the Tertiaries ; and after giving the 
percentages of related fossils, goes on to say, " We see a constant 
increase of the percentages from the Cretaceous to the [Miocene, and 
then again quite a sudden decrease from Miocene to Recent." 

As Dall and Ortmann have shown, some of the West Indian 
faunas used for purposes of comparison have been referred to the 
Oligocene, and this points to the Patagonian beds ha\ang a stronger 
affinity towards the Older Cainozoic than would otherwise appear 
from Ortmami's previous calculations ; and accordingly the latter 
regards them more decidedly as Lower Miocene.t 

The Relative Values of the Percentage Method; and the 
Comparison of Typical Faunas, in Determining the 
Ages of the Australian Cainozoic Strata. 

When Sir Chas. Lyell formulated the method of judging the age 
of the various Tertiary beds of the London, Hampshire and Paris 
Basins by the percentage of the recent species of mollusca contained 
therein, he was deahng with a set of strata deposited under 
fairly constant conditions, and dominated by an entirely 
different geographical distribution of land and water from that 
which must have prevailed more or less throughout Tertiary times 
in southern Australia. Since Lyell's time this once generally

accepted rule has been questioned. Kayser remarks*, '" Although 
the principle underlying this classification has in progress of time 
proved in the main accurate, the percentages of living species 
originally adopted by Lyell for the various groups have not remained 
firm. Thus for the Pliocene we must take 40-90 instead of 35-50, 
and for the Miocene 10-40 instead of 17." 

That the percentage method of correlating strata in widely 
separated areas is attended with serious difficulties has been early 
recognised, as, for example, by so able an observer of faunal 
distribution in the past and present as the late Capt. Hutton, of 
Christchurch, whose words on the subject we cannot do better than 
quote. After discussing the relative ages of two beds in the Wanganui 
System of New Zealand, which, on account of the close percentage 
of living to extinct species, Hutton was incHned to think, overlapped, 
and advocating the use of this same means of discrimination in 
determining the relative ages of beds in the same general area, he 
speaks thus : — f 

" But it does not follow that this method can be trusted for 
correlating with accuracy sets of beds in widely distant areas. On 
the contrary, different districts have undergone different physical 
changes, and we have therefore every reason to suppose that 
alterations in floras and faunas would proceed with unequal rapidity 
in different parts of the world. At the same time, as the replacement 
of a whole marine fauna can rarely be sudden, it follows that the 
percentage system has some value even here. But it must always 
be used in conjunction with a comparison of the specific forms of 
the two areas. And here, again, it is only the wide-ranging oceanic, 
or deep-sea species — such as sharks, cephalopods, and a few 
bivalves — which should be depended upon for evidence, but these 
wide-ranging forms are of the very greatest value in correlating 
strata all over the world." 

Another difficulty which confronts us with regard to the com- 
putation of the actual percentage of li\dng species is the variable 
estimation by different authors of the value of minor characters ; 
as, for example, of shell sculpture in the group of the moUusca, 
where shght differences are seen only after careful study, or it may be, 
a trivial variation in form, which, if sufficiently constant would be 
regarded by some as specific. Hence, critical work on any fauna 
will always tend to lower the jiercentage of living species in any given 
fossiliferous series, and consequently to ino'ease its approximate age. 
It seems, therefore, that we, in the southern hemisphere, to use the 
percentage method, must gradually erect a standard of percentages 
which will generally accord with the evidence afforded by a study 
of the strata in this part of the world ; never forgetting, however, 
to exercise a cautious spirit in regard to species-making in working 
from this stand-point.

RELATIONSHIPS OF THE AUSTRALIAN CAINOZOIC SYSTEM. 

Although Capt. Hutton mentioned certain groups of animals 
which, by reason of their comparatively deep sea habitat, furnish 
species of world-wide distribution, it appears highly probable 
that even these particular forms would be prone to considerable 
variation should they survive in an environment differing from that 
of the open ocean ; and this will account for the difficulty of 
discovering universally distributed species for comparative purposes. 
To aid in this matter of the comparison of facies of widely separated 
faunas other than recent, it may be suggested that generic types, 
no matter of what group of organisms, but which are limited to 
distinct horizons in the northern hemisphere, should also be regarded 
as of special value in the correlation of the Tertiary strata m the 
southern hemisphere. A comparison of selected faunal types, more 
or less indicative of distinct horizons elsewhere, will be made in 
drawing up a suggested stratigraphical correlation, and discussed in 
the notes following in the next section. 

In connexion with this subject, it is also necessary to draw 
attention to the recent work of Dr. A. E. Ortmann* as ha^•ing an im- 
portant bearing on the present question. From a study of the 
moUusca he has brought forward strong evidence in favour of 
correlating the Patagonian Tertiary beds with at least one of our 
southern Australian series, as well as with the Pareora formation 
of New Zealand, all of which he regards as Lower Miocene. 

With particular reference to the percentage method, Ortmann 
remarks! : — " In very many cases the age of the Tertiary deposits 
is determined by the percentage of living species found in them. 
In my opinion this line of evidence is entirely inadmissible in our 
case, and I hardly need to say anything to support this view ; this 
method may be safely used in Europe, but in the southern hemi- 
sphere it is out of the question." 

Dr. Ortmann further points out that, owing to the changes 
in the systematic views of the various authors of species, the number 
of the identifiable living forms fluctuates, and one or two doiibtful 
ones obviously lower the percentage considerably. This difficulty, 
as I have already mentioned, has frequently arisen in respect to the 
work of our Australian geologists, causing the same stratum to be 
referred to under three different age-names by as many authors. 
As a case in point, the work on the faunas of the Lower ^luddy 
Creek section and the Spring Creek beds by Drs. Hall and Pritchardf 
showed a percentage of living species as low as 2.5 per cent, for 
the former locality, and only about 1 per cent, for the latter. Since 
only 3 out of 293 species were identifiable with living forms in 
the Spring Creek fauna, it is clear that by addition of a few more 
recent species these beds might be reversed in apparent sequence, 
by the opinion of the investigator of doubtfully valid living species.

RELATIONSHIPS OF THE AUSTRALIAN CAINOZOIC SYSTEM. 



It is worthy of note that, in connexion with the subject of the 
value of the percentage method in its general sense, later research 
has already proved the survival of many other fossils of the Cainozoics 
in the seas of the present day. For instance, Lissarca ruhricata, 
now living in Western Port Bay and elsewhere, occurs in the 
Janjuldan of the Mallee bores ; and the Balcombian to Kalimnan 
Trivia avellanoides is found living off the New South Wales Coast. 

Some Cosmopolitan and Widely-distributed Fossil Types 
AND their Significance. 

Cetaceans. — In the Nodule or Phosphate Bed which is found 
at the base of the Kalimnan Series in Victoria, remains of cetacea 
are very abundant. They include ribs, vertebrae, an occasional 
scapula, digitals, tympanic bones, &c., evidently belonging to 
several distinct foims, and representing the Toothed Whales, 
including the Beaked Whales and the Dolphins. Similar remains 
are found scattered through the Janjukian Beds of Waurn Ponds 
and other localities where the strata are of considerable thickness, 
and marly or purely calcareous ; and this, with other data of fossil 
occurrences, show convincingly that the nodular phosphatic bed of 
the Grange Burn and that at the base of the cliffs at Beaumaris, 
which there underlie the Kalimnan, represent a remanie bed of the 
Janjukian series. 

One of the toothed whales {Odontoceti) occurring in Victoria is 
now referred to Parasqualodon, and another from South Australia is 
the type of the genus Metasqualodon* These are closely related 
to Squalodon, a typically Miocene form extending into the Pliocene. 
The teeth of the squalodonts form a more numerous and closer 
seriesf than those in the Eocene Zetiglodon; the former being smaller 
animals, with a shorter rostrum. The southern hemisphere 
squalodonts have the roots of the molar teeth united, whilst in the 
northern forms they are separate and incurved. McCoy described 
a molar tooth of " Squalodon " (= Parasqualodon) wilhinsoni from 
the " Miocene Tertiary sands of Castle Cove, Cape Otway Coast, "J 
in beds of Janjukian age ; and he subsequently figured another 
example, a canine tooth from Waurn Pounds, near Geelong. Several 
specimens both of the molar and canine teeth have since been 
found in the Waurn Ponds quarries in strata of similar age. In de- 
scribing the Parasqualodon teeth, McCoy compared them with Squalo- 
don grateloupi, H. von Meyer, from the Miocene of Bordeaux, from 
which they differ in the conjunction of the roots. Mr. E. B. Sanger, 
in 1881, described and figured a molar tooth of a cetacean under 
the name of Zeuglodon harwoodi,^ which has been made the

genotype of Metasqualodon, T. S. Hall. The specimens were found in 
yellow, calcaiTous clay oi! tlic Murray Rivor near Wellington, South 
Australia. The molariform teeth have shorter roots than in 
Parasqualodon, this constituting the chief difference. In a remark- 
ably well-preserved tooth of Metasqualodon ivilkinsoni, from Mt. 
Gambler, in the National Museum collection, the enamel of the crown 
is of a rich brown colour, and the surface covered with minute 
prickly tubercles. This example is embedded in the white polyzoal 
limestone of the locality ; the rock being in all probability equivalent 
to the yellow polyzoal limestone of Waurn Ponds and Jan Juc (Spring 
Creek). Although new genera have been instituted for these southern 
types of toothed whales, the conclusion as to their Miocene age is 
not affected thereby, as they are all members of the Squalodontidae, 
belonging to a higher zone than the Eocene Zeuglodonts. 

Fishes.^-lw two papers on the Tertiary fish remains of 
Australia, published by Dr. G. B. Pritchard and myself,* the general 
distribution and range in time of each genus and species was fully 
dealt with ; but no inference was then drawn as to the ages of the 
beds yielding these remains. It is there stated (op. cit. vol. 
XVII., p. 292) that " These data do not furnish any very clear 
evidence of our Tertiary succession and relative age of the beds, 
since the fauna has a general Tertiary aspect, but the occurrence of 
the few Mesozoic forms gives an aspect of antiquity to the older por- 
tion of our Tertiary strata." 

The genera discussed in those papers range from Jurassic to 
Recent, and none hav^e a restricted occurrence in Tertiary times. 
This at first sight is disappointing to the palseontological inquirer 
for exact data of chronological value. However, looking more 
closely into the relative abundance of the genera of sharks and 
other characteristic fishes of the Tertiary, we find that all the 
abundant generic forms are especially typical of Miocene strata 
in the northern hemisphere. Amongst these may be mentioned 
Galeocerdo, Odontasfis, Lamna, Oxyrhina, Carcharodon, Labrodon, 
and Diodon. Evidence of greater antiquity than Miocene is 
afiorded by the occasional occurrence of Asteracanthus, Edaphodon, 
and Ischyodus, which appear to be the survivors in Australian 
seas of types that are elsewhere found in earlier formations. This 
is a parallel case wdth the occurrence of Trigonia and other forms 
of archaic life found in the same area at the present day. 

With regard to the group of the sharks, the species common to 
southern Australia and the northern hemisphere are Carcharias 
acutus-\, Sphyrna prisca, Odontaspis contortidens, 0. cuspidata, 
Lamna crassidens, L. compressa, L. bronni, Oxyrhina hastalis, 0.

appears to belong to a recently recorded genus common to the Patagonian and Victorian

desori, 0. retroflexa, 0. eocaena, 0. tninuta, Carcharodon auriculatiis, 
and C. megalodon. Of these, 2 are northern Cretaceous forms, 11 
are Eocene, 1 Oligocene,* 11 Miocene, and 6 Pliocene. A closer 
scrutiny of these species reveals the fact that, whereas the genus 
may be recorded from both Eocene and JVliocfene, yet in regard to 
abundance and ubiquity the evidence of the species, as before stated, 
is decidedly in favour of a Miocene age for the majority of the 
fish remains in the older portion of our Tertiaries. 

With reference to the other fish remains in the Austra- 
lasian Tertiary, it is interesting to note that the Chimaeroids have a 
more ancient history elsewhere, whilst around Australia they lived 
in large numbers in the Balcombian and Janjukian seas. Our 
Tertiary Labrodon is comparable with the typical Miocene species 
of South Carolina, the Vienna Basin, Italy, Sicily, and Brittany. 
The Australian gymnodont, Diodon formosus, is most nearly allied 
to D. vetus from the Miocene phosphate beds of South Carolina. 
The fossils of this genus are commonest as Miocene forms. 

Mollusca.—Oi the tetrabranchiate cephalopods, the Aturia 
australis of McCoy is a typical fossil in the Australasian Tertiaries. 
It had an extraordinarily long existence, being found in the 
Balcombian, the Janjukian, and the Kalimnan series ; although 
it seems to be more common in the blue clays of the Mornington 
and Muddy Creek beds (Balcombian), where it often attains a 
large size. An exceptionally fine specimen from Muddy Creek in 
the National Museum collection measures 17.5 cm. (nearly 7 
inches) in diameter, and about 6 cm. across in the umbilical region. 
This species is distinct from the Lower Eocene form, A. ziczac, to 
which it was formerly referred, in having more compressed sides. 
In this respect it is similar to A. aturi, Basterot, originally described 
from the Miocene of Dax, France, and also occurring at Turin and 
Malta in beds of the same age. 

The true Nautili are also well represented in our faunas, but up 
to the present only one form has been described, viz., N. geelong- 
ensis, Foord,t which that author compares with N. regalis, J. Sow. 
The London clay species differs, as Foord remarks, in that " it is 
a more inflated shell, and its sutures much less flexuous." Examples 
of what appear to be the same form, in the National Museum collec- 
tion, are from the Moorabool Valley, Victoria, and the cliffs of the 
Lower Murray River in South Australia (Janjukian). 

The dibranchiate cephalopod, Spirulirostra, is one of the most 
remarkable genera of the Australian fauna. The only southern 
species, S. curta, made its appearance suddenly, but after a very 
short existence as quickly died out. It is strictly confined to 

* The low number of records from the Oligocene is probably accounted for by the fact that 
certain beds of this system were previously regarded as Eocene. A revision of these records 
would possibly raise the number for the Oligocene.

Miocene strata, and in Australia to a very limited horizon of a few 
feet in thickness in tlie Janjukian of Spring Cr^jek, near Geelong. 
Until the Australian species, S. curia, Tate,* was described, this 
genus was represented by two species only, viz., S. hellardii, 
d'Orbigny, from the tfiocenc of Turin, f and S. hoernesi, von Koenen, 
from the Miocene of Dingden, Berssenbriick.| 

The remaining groups of the mollusc are not especially repre- 
sented in the Australian Tertiary by genera restricted to any 
particular horizons elsewhere ; but the Australian beds are rich in 
species of gasteropods, bivalves, and other invertebrates, related to 
these in the Tertiary faunas of the northern hemisphere, and to 
which reference will be made. 

Echinoidea. — The Australian Tertiary fauna is rich in echinoids ; 
and these furnish some interesting data in regard to closelv related 
forms found in the northern hemisphere. When first authoritatively 
examined, our fossil sea-urchins were pronounced by Profs. P. M. 
Duncan and J. W. Gregory and others to have a decided 
Cretaceous aspect. This opinion has since been abandoned in 
consequence of the characters of the Australian species having 
been more clearly defined, showing them to be distinct from 
apparently related but older forms, as for example, Holaster 
(Cretaceous), and Duncaninster (IMiocene). Certain genera, as 
Cassidulus, Plesiolampas, and Prenaster, are Eocene elsewhere. 
Echinoneus is a genus ranging from Miocene to Recent in other 
areas. It is represented in our faunas by E. dennanti, T. S. Hall, 
and is found in the Batesford limestone associated with a Miocene 
foraminifer, Lepidocyclina. Clypeaster, although unrestricted, attains 
its maximum development in the Miocene faunas, as at Malta and 
the south of France. Linthia has a range from the Cretaceous to 
Recent, but is typically a Miocene form. It is represented by 
several species in our Janjukian series ; L. antiaustralis, Tate, 
occurs at Curlewis in beds of that age, whilst L. mooraboolensis, 
Pritchard, is found in the Batesford limestone associated ^"ith 
Miocene foraminifera, as Lepidocyclina nmrginata and L. tournoueri. 
Another unrestricted genus but typically ]\Iiocene, is Schizaster, 
and one of its species, *S. sphenoides, T. S. Hall, from the 
Barwonian of the Sherbrooke River, is almost identical with S. 
scillae, Desmoulins, a typical Miocene form in Europe. 

Foraminifera. — The general facies of the foraminifera from

Cotnparative Types. — The following comparative types of 
European Tertiary fossils have been selected as comprising some of 
the more strildng forms which are isomorphous with the Australian 
species. It is by no means an exhaustive list, but will serve to 
illustrate the trend of evidence now brought forward, which proves 
that the greater part of the southern Australian series is of Mocene 
age ; whilst below are beds of Ohgocene to Lower Miocene, and 
above, of Pliocene, ages : —

Ox the Absence of Nummulites in the Tertiary of Southern 

Australia. 

One of the chief factors which gave support to the conclusion 
that the Australian Tertiary beds belong in part to the Eocene or 
Nummulitic formation, was the erroneous record of the genus 
Nummulites from the lower beds at Muddy Creek, near Hamilton, 
Victoria. The nummulinoid foraminifer occurring so commonly 
throughout the main portion of our Tertiaries was, however, correctly 
assigned to the genus Amphistegina as early as 1865 by Tenison 
Woods*, for whom, as before stated, it was named by Prof. Rupert 
Jones. In describing the foraminifera from Muddy Creek, Woods 
writes as follows :,— " The foraminifera are large and numerous ; 
indeed one species, Amphistegina mdgaris, d'Orb., is so common 
that the clay is principally composed of it. Its large lenticular 
form can be traced in almost every pinch of the debris, and what 
makes the individuals more conspicuous is that they have all 
received the ferruginous glaze which makes them look like little 
coins. Prom their numbers the strata may in truth be called an 
Amphistegina-hed, similar to that in Vienna, and possibly of the same 
age. Other Foraminifera occur, such as Discorbina turbo, Pulvimdina 
ptdchella, Planorbulina Haidingeri, Operculina complanata, Poly- 
morphina lactea, Textularia sagittula, Miliolina semiluna, and M, 
irigonula. Next in frequency to the Amphistegina vulgaris is the 
Operculina complanata. Bast., and though equal in size to the 
species found at Mount Gambler, it is much more common in the 
latter locality." 

The earliest reference to the supposed occurrence of Nummuhtes 
in AustraUa appears to be that given by T. R. Jones in 1882, j 
when a descriptive note on specimen P. 253 in the British Museum

was published, reading as follows : — " Small Nummulites (near N. 
variolaria) and Amphistegina ? In the Muddy Creek Tertiaries 
(Hamilton beds). South Australia.* T. Rupert Jones Coll." 

The previous deterniination made by Prof. Jones in 1865 was 
the correct one ; and here he was evidently misled by the large 
size of the Amphisteginae, which on casual inspection might be 
readily assigned to the genus Nummulites. In his earlier deter- 
mination, Rupert Jones had, without doubt, carefully examined 
these forms and satisfied himself as to their amphistegine nature. 

Mr. Walter Howchin, in his valuable and comprehensive 
account of " The Foraminifera of the Older Tertiary of Australia 
(No. 1, Muddy Creek, Victoria). "| recorded Amphistegina lessoni, 
d'Orb., and Nummulites variolaria, Sow., from the upper and lower 
beds (Kalimnan and Balcombian), and mentioned in the descrip- 
tion of N. variolaria the ])robability of the specimens from the 
upper bed being derived from the lower bed. 

In the course of work on the Tertiary fossils of southern 
Australia since 1902, I have had occasion to microscopically 
examine samples of foraminiferal rocks from nearly all Victorian 
and many South Australian and other localities, and in every 
case have failed to find a true Nummulite, although many 
specimens were put aside as doubtful until sections were made 
from them. Latterly I wrote to my friend, Mr. Howchin, 
asking him for samples of the supposed Nummulites Avhich he 
possessed. These he very kindly forwarded, and on my returning to 
him sliced examples of the shells, Mr. Howchin concurred with me 
as to their relationship with Amphistegina. At the same time he 
very generously favoured me with a note for publication which will 
explain how the confusion had arisen in the determination of these 
difficult forms. 

Mr. Howchin writes : — " When working up the foraminifera of the 
Muddy Creek beds, I was writing to Brady on sundry matters, and 
enclosed a few of the large nummuline-like forms that are a 
proininent feature in the Muddy Creek material. Under date, 
25th October, 1886, Brady replied as follows : — ' Firstly with regard 
to your specimens. 1. Nummulites in quill. So far as can be made 
out, this does not materially differ from Num. variolaria — assuming 
these are fully-grown species and not the young of some larger 
species. I do not altogether trust my laaowledge of the distinctions 
marking the allied varieties of this group — the subject has become a 
special one. However, von Hantken, of Pest, to whom I was writing, 
and enclosed one or two of the specimens, replies to the same effect.' 
I am afraid that I accepted too readily, and without due examination, 
the testimony of those two experienced authorities. It is only fair

naturalists.

to say that neither Brady nor von Hantken made sections of the 
specimens, and the very large size of tlie Ampliistegina was no doubt 
a misleading factor in the determination." 

This common little nummulinoid species of the Australian 
Tertiaries is without doubt referable to A. lessonii, d'Orl)igny ; and 
the fresh or unworn examples resemble the variety found in the 
Vienna Basin, known as A. hauerina, d'Orb. Some of the larger 
specimens occurring in the Balcombian marls of Muddy Creek, 
T. Woods remarked upon as being " glazed with a ferruginous 
deposit." It appears, however, that abrasion and polishing has 
occurred in these examples, presumably by aeolian agency, and that 
they have been subsequently stained by the action of ferriiginous 
water. The large sized tests of the Amphisteginae found in the Muddy 
Creek shell-marl can be matched by those from moderately shallow 
water of tropical or subtropical areas. At Funafuti the examples 
of this genus are similarly of large size, and frequently AA'ind-wom 
or even polished ; the latter character appearing on specimens of 
the tests from various depths in the deep boring. Atnphistegina 
lessonii occurs at Funafuti at all depths down to 200 fathoms, and it 
was at its largest at about 36 fathoms.* 

For the convenience of workers in other fossil groups who may 
not be conversant with the characters separating the genera 
Amphistegina and Nummulites, the following table is given.

The Evidence of the Complex-structured Foraminifera in the 
Australian Tertiary System. 

The shells of foraminifera exliibit great diversity of form, as 
well as a wide range of complexity in shell-structure. It is too 
often assumed that, because these ubiquitous marine organisms 
belong to the lowest phylum of the animal kingdom, they cannot 
therefore be of value in helping to decide the age of the beds in which 
they occur. This, however, is far from the truth, for, prima facie, 
no one with a special knowledge of palaeontology would dispute the 
proofs of the restriction of the Nummulites to a limited series of 
strata (Eocene and OUgocene), or ignore the zonal value of certain 
species of tlie genera LepidocijcUna and Miogypsina. 

With regard to the genera of foraminifera which possess simply 
constructed tests, we may for the present disniiss these from 
consideration ; for, although they have a certain distributional 
value in affording evidence of geographical facies dominated by local 
conditions of life, or controlled by sedimentation and hydrographical 
factors, there is a much more important section to be dealt wnth in 
the specialized forms constituting the Family Orbitoididae, and 
some other more or less related forms with highly speciahzed shell- 
structure. 

Gypsina howehini, Chapman.— I have already shown* how closely 
the above species agrees with the Miocene ancestor of Gypsina, \az., 
Mioqypsina. The chief difference lies in the absence of the vertical 
pillars as seen in cross-sections of Miogypsina ; the only differentia- 
tion of the chamberlets in the median plane in the test of G. howehini 
being in their more spacious character.| 

Amphistegina lessonii, d'Orbigny.— The inequilateral Amphis- 
tegina took the place of the equilateral Nummulites towards the close 
of the Oligocene, and was the predominant form in many foraminiferal 
deposits of Miocene age. J 

Cycloclypeus pustulosus, Chapman.— This species is, so far as 
known elsewhere, confined to the IMiocene (Burdigahan), being 
found in the Island of Santo, New Hebrides, where it is associated 
with Miogypsina burdigalensis, Giimbel sp. ; M. complanata, 
Schlumberger ; M. irregularis, Michelotti sp. ; Amphistegina lessonii, 
d'Orbigny •' Heterostegina depressa, d'Orb. ; H. margaritata, Schl. ; 
Lepidocyclina mwtini, Schl. ; L. andrewsiana, Jones and Chapman ; 
and L. insulae-natalis, J. and C. 

With regard to the Orbitoididae, this group has a range froni the 
Cretaceous to the Miocene. In southern Australia these foraminifera, 
represented by the Ohgocene-Miocene genus Lepidoeyclina, play the 
very important part of forming a large proportion of certain lime- 
stones such as those of Batesford and Keilor ; whilst they are also

found, often in al)undance, in the sliallow-water deposits of some of 
the beds in the Tertiary series, sucli as those of Clifton Bank, Muddy 
Creek, and Waurn Ponds, near Geelong. 

The earliest reference to the " Orhitoides " group in the southern 
Australian Tertiaries was made by the Rev. W. Howchin, F.G.S., 
who, in 1889, recorded Orhitoides dispansus, Sowerby, 0. mantelli, 
Morton, and 0. stellata, d'Archiac, from the lower beds at 
Clifton Bank, Muddy Creek, near Hamilton, Victoria.* An 
examination of the median layer of the Muddy Creek forms shows 
them to belong to the genus Lepidocyclina, a group that was 
imperfectly worked out when Mr. Howchin made his determinations. 
The lepidocycline relationship was suggested by Lemoine and 
Douville in their paper, " Sur le Genre Lepidocyclina, Gumbel,"! 
where they say, " a Muddy-Creek (Victoria), dans des couches que 
Ton considere comme d'age eocene, M. Howchin a signale 0. mantelli 
et 0. steUata d'Archiac ; cette derniere forme, d'apres la description 
de M. Howchin, possede desloges hexagonal es et doit, par suite, etre 
rangee dans le genre Lepidocyclina." This latter form I had already 
determined to my own satisfaction as belonging to that genus, and 
have since been able to refer it to L. martini, Schlumberger. 

In 1891 Messrs. Hall and Pritchard recorded Orhitoides mantelli 
from the Filter Quarries and Upper Quarry at Batesford ; and also 
at Griffin's and near Madden's in the Moorabool Valley to the south- 
east of Batesford. I These specimens were identified by Mr. Howchin. 

Genus Lepidocyclina, Giimbel. — Examples of the genus Lepido- 
cyclina have been collected by me from four of the known localities 
in Victoria, and this collection has been further increased by specimens 
kindly given me by Dr. T. S. Hall. The localities furnishing this 
interesting group of foraminifera are, in the Balcombian series — 
Clifton Bank, Muddy Creek ; in the Janjukian series — Waurn Ponds, 
Batesford, Griffin's, near Madden's, along the Moorabool Valley, 
all near Geelong; and at Green Gully, Keilor. Quite recently I fou:~d 
a rich horizon for Lepidocyclina in Western Victoria, in the Janjukian 
limestone of the Granee Burn opposite Mr. Henty's farmstead. 

It has already been pointed out in another place§ that, whilst 
the Burdigalian species, Lepidocyclina iournoueri, Lemoine and 
R. Douville, occurs in great abundance at Batesford, the Keilor 
ferruginous limestone contains, besides this form, another species, 
L. verheehi, Newton and Holland, a species also met with at Clifton 
Bank (Balcombian). This fact seems to point to the Keilor horizon 
representing, although Janjukian, a bed slightly older than the 
Batesford limestone. To illustrate this more clearly we may note

that Douville has pointed out* that the Lepidocyclinae fall into two 
groups : — 1st. The L. dilatata group, in which the vertical pillars are 
small and uniformly distributed over the shell, the test being 
typically large, as L. chaperi, L. insuhe-natalis, L. verbeeki, and L. 
elephantina. 2nd. The L. marginata group, in which the pillars are 
more or less developed, but always more crowded towards the centre 
of the test, as L. raulini, L. morgani, L. toumoueri, L. suhmarginata, 
and L. sunuitrensis. 

The beds in Borneo, Italy and Panama (San Juan), characterized 
by the first group, that of L. dilatata, belong to the Aquitanian stage. 
The beds in Borneo, the south of France and Panama containing 
those of the second, L. marginata group, belong to the Burdigalian 
stage, t 

The distribution of the Victorian forms of LepidocycUna may 
best be shown by the following schedule : —

F. Sacco has studied the faunas containing LepidocycUna and 
Miogypsina vnih especial regard to the Tertiary basin of Piedmont, 
Italy ; and, although he differs from Douville and Prever with 
reference to the precise horizon of L. marginata in that .area, yet that 
question does not affect our present conclusions. M. Sacco fixes 
the L. marginata beds as Aquitanian (but Miocene), whilst Douville 
and Prever place them in the Burdigahan (still Miocene). The 
succession remains the same, and the periods follow suit. It is thus 
merely a local adjustment of terms. J 

Prof. A. Silvestri, in his " Distribuzione Geografica e Geologica 
due Lepidocicline communi nel Terziario Italiano,"§ cites 
the occurrence of both L. dilatata and L. toumoueri in the 
Priabonian (Oligocene) in Italy and Greece, and their recurrence 
in Italy in the Miocene. In the former instance those species are 
associated with more archaic forms, as the striated nummulites 
and Chapmania, which, however, are absent from the Australian 
Tertiaries.

Stratigraphical Notes bearing on the Sequence or the 

Strata. 

A. — The Port Phillip Area. 

A boring at Sorrento close to the Port Phillip Heads has 
been lately put down by the Mines Department of Victoria to a 
depth of 1,693 feet.* The results obtained from this, perhaps the 
most valuable boring from a scientific stand-point which has yet 
been made in the Cainozoic strata in this State, sets at rest any 
doubt as to the succession of these beds. In the marls from 
1,310-1,426 feet there are bands of Vaginella eligynostoma, a 
pteropod occurring in the fossil beds at and above sea-level at 
Mornington and Grice's Creek, about 18 and 22 miles to the 
north-east. This difference in level of the same strata between 
the two places within so short a distance is explained 
by the fact that the great Dandenong to Cape Schanck 
fault cuts between the two areas ; Sorrento, being on the down- 
throw side, and Mornington and Grice's Creek on the upthrow side. 
These lowest beds of the bore are proved by their fossil contents 
to be of Balcombian age. In the same boring Janjuldan marls are 
distinguished, at 990 and 758 feet, by containing typical Spring 
Creek fossils, as Eutrochus fontinalis and many others. From 
741 to 585 feet Limopsis beaumariensis and other typical Kalimnan 
fossils denote this portion to belong to the upper series. Above 
this again, the Werrikooian or Upper Pliocene is represented probably 
between 585 and 489 feet ; whilst above this comes a Pleistocene 
and Holocene succession of estuarine muds and sand-dune rock. 

The Cainozoics at Sorrento were not bottomed at 1,693 feet. 
Judging from the exposure of Mesozoic shales \Anth Thinnjeldia on 
the foreshore south of Grice's Creek, it is highly probable that the 
Cainozoics at Sorrento may rest on these same Mesozoic rocks. 

Follo\ving the Port Phillip coast-line in a north-easterly direction 
beyond Dromana, we find, at the north end of Balcombe's Bay, t^'pical 
Balcombian blue clays ^vith septaria containing Vaginella eligmostoma.

reveals a thick series, about 80 feet in extent, of a grey clay with 
gypsum similar to that north of the Cement Works, and which is 
evidently part of the same Balcombian series. The upper beds are 
seamed with fracture-lines due to local faulting, and through these 
minor rifts percolation has taken place through the surrounding 
strata containing pyritous matter, resulting in the replacement of 
the fossil shells by gypsum (Fig. 2). The occurrence of the marl-bed

sea. i-g~«l 



at this place is compatible with the general character of an Oligocene 
fluvio-marine series, as typified on the other side of the Bay at 
Newport and Altona. The relationship between the older basalt 
and the Balcombian clays is obscure at this part, owing to the 
maslving by landslips and extensive faulting ; but near Landslip 
Point* the basalt is seen to overlie the granite and conglomerate, 
the latter being referred by Messrs. Hall and Pritchardf to the 
Balcombian or older, and to underlie the fossiliferous ironstone 
conglomerate with a typical Janjukian fauna. In a recent visit to 
Frankston, Mr. R. A. Keble and the writer obtained several restricted 
Janjukian fossils from the fossihferous ironstone ; thus linking this 
bed with similar ironstones at Flemington, Keilor, and South 
Yarra (see postea, p. 29). 

Older basalt is met with at various points along the coast, as 
between Checbingurk Creek and Mornington, between Mornington 
and Grice's Creek, and between Wallace Bay and Frankston. { 
Leaf-bods also occur, associated " with quartz pebbly drift "... 
" in the base of a high cHfE in Balcombe Bay,"§ and Mr. Kitson 
thinks the leaves resemble those of the Janjukian at Sentinel Rock, 
Cape Otway. Mr. J. S. Green has lately obtained some leaves from 
these beds, which show a marked resemblance to the genera 
described by H. Deane from Berwick, as Apocynophyllum, cf. 
Tristanites, Lomaiia, and cf. Fagus. No leaf-beds were met with

ill the SorroMtn Boro, so we may foiuhuU' that tliat area was outside 
the infhicnce of fluviatile conditions of tlie continental seaV^oard of 
that time. As regards Kitson's reference to these leaf beds as 
resembling tliose of the Otway Coast, it is interestii-g to note that one 
specimen collected by Mr. J. S. (ireen is practically identical with 
branchlets of a Casuarina from Sentinel Rock.* 

The exact relationship of the basalt to the Balcombian blue 
clays in the Mornington district appears to be obscured by slipping 
and faulting ; but at Grice's Creek, Drs. Hall and Pritchard mention 
that these clays are "succeeded by basalt, which occupies the bed of 
the stream for nearly a chain, and over which the ascent is steep. "f 
In the Table of Rock-Succession, however, the same authors:}: place 
the basalt below the blue and grey clays, and above the lignitic 
beds ; and in another place§ mention the occurrence of grits and 
conglomerates (lignitic) as " passing under a small mass of basalt 
which shows well-developed tabular jointing." This basalt is not 
seen intercalated between the clays and lignites in the cliff sec-tion 
at Balcombe Bay. Hall and Pritchard offer two possible explana- 
tions of this problem. Either a narrow stream of lava flowed down 
an eroded valley, cutting through the upper sandy beds till the

lignitic series was reached, or a sheet of basalt was laid down ujjon 
the lignitic series, and subsequently partially removed by denudation 
before the deposition of the overlying sandy beds.

The most clearly defined section of this much disturbed and 
masked coast-line is that given by Mr. Kitson,* from Landslip 
Point to Narringalling Creek (Kackeroboite Creek of Kitson). At 
Landslip Point (Fig. 3, a generalized section) the succession is 
shown to be : — 

6. Ferruginous sands. 

•5. Ferruginous grits with fossils. 

4. Basalt. 

3. Hard ferruginous grit. 

2. Conglomerate (with slate pebbles). 

L Granite. 

The discovery of fossils in the ferruginous bed No. 5 mentioned 
above was made some years ago by Mr. Kitson, F.G.S., who, in his 
paper, " Report on the Coast-line and adjacent Country between 
Frankston, Mornington, and Dromana,"f stated that " The [fossil] 
casts obtained have been examined by Mr. Dennant, who unhesi- 
tatingly pronounces them to be of Eocene age." 

A fairly extensive series of fossils from this ferruginous band 
was obtained and recorded by Hall and Pritchard in 1 90L J Although 
their list comprises 36 species, none of them seems to be restricted 
to Balcombian strata. In point of fact, an examination of that list 
shows that the affinities of the species enumerated lie as closely with 
a Janjukian as a Balcombian facies, mth which latter series Hall 
and Pritchard state they " show a close agreement." 

During the last year I have visited this locality in company 
with Mr. R. A. Keble, and we have made a fairly comjjrehensive 
collection of the ironstone fossils. The impressions, as a rule, are 
very clean, and in some cases even the shell is preserved. Several 
of the forms found are not>eworthy as being restricted Janjukian 
species, and as such give strong evidence as to the precise age 
of this band of ironstone. The fossils amongst the collection 
made by us which are new to the already published list referred to 
are : —

Of the above forms the following are worthy of especial note : — 
Sphenotrochus enuircialus has a remarkably extensive range, being 
found alike in Balcombian, Janjukian, and Kalimiiau strata. 
Ditrupa cornea, var. wormbetiensis is especially typical of Janjukian 
beds ; it is a characteristic and abundant fossil in the polvzoal rock 
of the Mallee Bores and of the upper limestones of the Spring Creek 
series, and so far as I am aware, only a single specimen has occurred 
in the Balcombian, at the top of the series, at Miiddy Creek. The 
brachiopod provisionally referred to Terebratula (?) aldmgae is a 
cast, which, by its compressed shape and outline, is nearest that 
species, only occurring in Janjuldan strata ; the squarish anterior 
is matched very closely by specimens in the Dennant collection ; 
and the only other species with which it could be compared is T. 
vitreoides, T. Woods, also a Janjukian form. Fecten praecursor is a 
specially characteristic Janjukian form. P. flindersi is also of 
similar age, being found at Aldinga. 

From Mornington towards Frankston, and over the hinterland, 
thick deposits of fine and coarse sands, often ferruginous, are largely

but the lower portion is undoubtedly of Janjukian age, as sho'mi

above, and comparable with those beds known elsewhere, as in 
Western Victoria, as the " older gold-drifts." The general sequence 
of the strata in Port Phillip between Frankston and Mornington 
appears to be easily explained by the accompanying diagram (Fig. 4). 

Still on the downthrow side of the great fault of Port PhiUip 
and on the opposite (west) side of that great inlet, are situated 
Altona Bay and Newport, at which places deep shafts have been put 
down, extending into Balcombian strata, and affording a continuous 
series from surface level. These bores reveal several seams of lignite 
or brown coal, one of which is 74 feet in thickness. Unfortunately, 
no detailed and scientific 
account of the strata 
passed through in these 
bores is available, but the 
data given by the engineers 
show that the beds are 
very variable in character, 
and a general idea may be 
gained as to their nature. 
The bed-rock, probably an 
Ordovician slate (Fig. 5), 
was struck in Bore No. 1 
at Altona Bay (Sect. VII., 
parish of Truganina) at 
656 ft. 3 in., and pene- 
trated a thickness of 
238 ft. 4 in.* Above this 
bed-rock there is a variable 
series of gravelly sands 
and lignitiferous clays, 
with occasional seams 
containing broken shells, 
which amounts to a thick- 
ness of 235 ft. 6 in. Above 
this, again, occurs a brown 
coal bed 70 ft. 5 in. thick. 
The succeeding calcareous 
clays and limestones, as 
well as those just men- 
tioned, are of Balcombian 
age, and have yielded an 
extensive faima, chiefly of

also include the occurrences from the Newport Bores. Above the 
calcareous clays there are alternating bands of ferruginous 
clays and sands, which afford strong evidence of belonging to the 
Janjukian series of the Corio Bay marly facies ; smce from these beds 
Messrs. J. S. Green and W. J. Parr have obtained many fine examples 
of the large Magellanias characteristic of the beds at Corio Bay, 
which crop out to the south-west at the locality named. As 
collecting on the spoil-heaps from these borings has been done 
somewhat indiscriminately, it is possible tliat the published li.sts of 
fossils from these localities may include some forms which are not 
actually from the Balcombian series. 

In the report of Messrs. Thiele and Grant it is stated that this 
" cream-coloured sandy clay, with nodules of yellow hmestone 
. . . . isvery full of foraminifera (largely of the genus OjaercuZina), 
and contains a fair number of brachiopods, but few gastropods or 
lamellibranchs." The brachiopods were not included in their 
list.* They also noted the uppermost bed as consisting of " a 
coarse ferruginous grit," in which they " failed to find any traces 
of fossils." In all probability this bed is the equivalent of the 
marine Kalimnan series of Brighton and Beaumaris and the subaerial 
sands of the Melbourne district. 

Crossing again to the eastern side of Port Philhp, and on the 
Melbourne side of Frankston, the cliffs in the neighbourhood of 
Beaumaris are mainly composed of the Kalimnan beds, consisting 
of ferruginous clays and sands, which contain typical Kalimnan 
fossils, as Limopsis beaumariensis and Trigonia margaritacea, var. 
acuticoatala. On the foreshore may be commonly found teeth of 
sharks, many of which are common also to the nodide bed seen at 
the Grange Burn and on Muddy Creek ; and which by their position 
there are seen to form the basal bed at Macdonald's and Forsyth's. 
Although the beds on the foreshore at Beauinaris are covered by a 
thick deposit of shingle, it has been proved that, by sinking a shaft 
for a few feet, the basal nodule bed is exposed in situ. By a 
comparison with the beds of the Hamilton district it is evident that 
the rolled fossils of the nodule bed constitute a remanie fauna, 
whilst the surrounding clay contains indigenous Kalimnan fossils. 

B. — Flinders. 

An interesting little patch of polyzoal limestone is found on the 
coast at Fhnders, resting on the older basalt. The limestone has 
evidently been deposited in an eroded hollow on the surface of the 
lava,t and it has a maximum thickness of about 20 feet. The 
fossils contained in this friable limestone show unniistakeable 
affinities with the Cainozoics of the Moorabool Valley and Curlewis,

both of which must be referred to the Janjiikian. For instance, the 
numerous Amphisteginae* present in the FHnders rock make it 
comparable to the Filter Quarry stone at Batesford ; whilst the 
occurrence of an abundance of calsisponges shows its time-relation- 
ship with Curlewis and the Moorabool section at " Griffin's." At 
Curlewis I have lately obtained numerous examples of Tretocalia 
pezica, which were only recorded previously from Flinders. Other 
Janjukian (restricted or Jjost-Balcombian) fossils found at Flinders 
are — Arachnoides (MonostycMa) australis, Cidaris {Leiocidaris) 
australiae, Pecten gamhierensis, and P. subhifrons. 

Besides affording positive evidence for a Janjulcian age, it is 
interesting to note that this limestone rests on the older basalt 
(Fig. 6), as does the fossilifcrous ironstone of the Flemington railway 
cutting and many other Miocene (Janjuldau) occurrences. Whilst 
far from assuming that the older basalt so-called represents an 
effusion of one definite period, it is always so closely associated 
with those beds, which are proving themselves to be merely different 
lithological phases of the great Janjuldan and Mount Gambier 
series, that we are forced to the conclusion that during this period 
of maximum sedimentary deposition on the southern Australian 
coast, an intermittent series of flows were poured out of a generally 
dense, magmatic basalt, which in some measure represents the 
relieving outbursts consequent upon the extraordinary strain that 
was exerted at that period on the continental shelf.

The Flinders limestone, by the abundance of its foraminifera, 
polyzoa, and calcisponges, indicates a fairly deep water and 
tranquil condition, with little or no solution of the ferruginous 
constituents of the volcanic sea-bed. At Flemington we have 
the opposite conditions, of a shore-line with littoral shells, as 
Haliotis and Patella, and much alteration of the original shell- 
conglomerate, resulting, by its absorption of iron probably both 
from above and below, in a highly ferruginous rock. 

An extremely interesting discovery was lately made by Mr. 
R. A. Keble, of the Mines Department, of a small patch of polyzoal 
rock resting on older basalt at the back of Cape Schanck. The 
position of this rock is about 1 mile north-west of the junction of the

Lighthouse and Sorrento roads. Besides generally resombling the 
Flinders limestone, to which horizon it clearly belongs, it proves on 
examination to contain tests of Lefiducyclina, the first recorded 
east of Port Phillip, the previously known localities being Batesford, 
Keilor, and Muddy Creek, Hamilton. This occurrence strengthens 
the view that the beds in the Moniington. district also, that overlie 
the older basalt, belong to the Janjukian and not to the Balcombian, 
as Hall and Pritchartl supposed,* judging from their examination 
of the fossils at Landslip Point, Frankston. This assemblage, by 
the way, does not contain any restricted Balcombian species, for even 
Vaginella is found very sparingly as high in the geological series as 
the younger beds of Muddy Creek (Kalimnan), according to the list 
of Dennant and Kitson."|' Moreover, the Frankston locahty contains 
some restricted Janjukian species, as shown earlier in this paper. 
The reason one might advance for the absence of Lefidocydina 
from the Flinders limestone is its deep-water aspect, the foiaminifera 
belonging to that genus appearing to favour shallow to moderately 
deep-water conditions, but this evidence is not conclusive, since 
the Filter Quarry deposit is both polyzoal and Lepidocycline in 
constitution.

RELATIONSHIPS OF THE AUSTRALIAN CAINOZOIC SYSTEM. 

The fossil determinations and age of the rocks were reported 
upon by McCoy* ; and their joint conclusions are very nearly the 
same as advanced in the present work. A similar sequence is given 
by Mr. Dennant,f who, however, relegates the two beds to the 
Eocene and Miocene respectively (Fig. 7). 

As shown in the previous part of the present paper, the 
subdivisions of the Cainozoics are regarded by the latter author as 
of greater age than is justified by the fossil evidence. The Bairnsdale 
and Mitchell River limestones and calcareous fossil beds contain a 
facies resembling the polyzoal series of Mount Gambler and the 
Corio Bay marl beds. The difference in the two series, of the 
Bairnsdale and Mount Gambler deposits, lies in the fact that in the 
former the marine conditions during the Miocene were of a shallow- 
water nature, more akin to that of the Corio Bay series, as shown by 
the community of fossils, such as Hinnites corioensis. At Sale, in 
similar beds (Dutson's Quarry) the rock is a true Amphistegina 
limestone, like that of the middle series at Grange Burn, and the 
Flinders limestone. At Bairnsdale a large echinoid, the Clypeaster 
gifpslandicum, is fairly common ; it is a form which also occurs in 
the lower (Balcombian) stage at Muddy Creek, but of smaller 
dimensions, and in the higher (Kalimnan) stage at Beaumaris, 
where it is also of less size than at Bairnsdale. This is one of many 
good examples in Victoria of the law of maximum development in 
the Miocene. Another fossil we may note from Bairnsdale, but 
which is restricted to beds of Janjukian age, is Sfondylus gaedero- 
foides, being found in common at Maude, Torquay, the Aire coastal 
beds, in Victoria, and Table Cape, Tasmania. Of these localities, 
there can be no doubt regarding their stratigraphic position. 

The upper series in the IVIitchell River district, as shown by 
Mr. Dennant,t is referable to the beds now classed as Kalimnan 
(Miocene of Dennant and others. Lower Pliocene of McCcy and the 
present writer). Many of the fossils found therein are also common 
to the upper beds at Muddy Creek. A part of the fauna, however, 
(that of Jemmy's Point), indicates deep-water conditions as compared 
with that of the last-named locality ; and the fauna, as a whole, is 
perhaps more comparable with the deposits which were laid down 
in the Kalimnan sea of the Murray Gulf, now found underlying the 
Mallee district of Victoria and South Australia, and also of Beaumaris. 
As a case in point, Turritella fctgodula may be mentioned, which is 
a common fossil in the Mallee bores, and also found in the Beaumaris 
cliffs. Evidence as to deep-water conditions in the Kalimnan beds 
at Jemmy's Point is seen in the aspect of the foraminifera, several

species of which indicate deeper bathymetrical surroundings than 
the upper heds at Muddy Creek, and clearer water than prevailed 
in the Beaumaris area. 

The view that the Bairnsdale limestone indicates a somewhat 
low horizon in the extensive and extremely variable Janjukian 
series is supported by the fact tliat the two Tertiary groups as 
revealed in geological sections along the course of the Mitchell River 
in the Bairnsdale district are luiconformable.* Here, as indicated 
by Dr. Howitt, the Upper Cainozoics rest on an eroded surface of the 
Bairnsdale limestone. This is also clearly set forth by Messrs. 
Dennant and Clarke, | wlio state that at Rose Hill, " Immediately 
underlying the Miocene [Lower Pliocene] marls there is the typical 
Eocene [Miocene] limestone of the area, which was here evidently 
an eroded surface when the later beds were deposited upon it." 
The same authors also record the Kalimnan series at Belle Vue, 
represented by a fossiliferous ironstone bed. 

D. — The Geelong Area. — Corio Bay. 

The strata exposed in the low sea-clifi of Corio Bay consist of 
yellow and occasionally greyish shelly and earthy marls, in which 
the large Magellanias, large Pectens, and solitary corals are 
conspicuous. The beds are evidently an argillaceous phase of the 
Janjukian stage. An extensive comparison of the fauna with 
that of some Balcombian marls would at first sight lead one to 
suppose the ages of the two beds to be identical, so many species of 
mollusca and other fossils being common to both beds. If, however, 
we test the faunas from these beds and select the restricted species, 
we find the following list of nine species of fossils present in the 
Corio Bay series, J which are elsewhere entirely confined to Janjiildan 
localities. They are : — 

Bullinella pauGilineata, Tate and Cossman. 

Ancilla ligata, Tate sp. 

Scala echinophora, Tate sp. 

Turbonilla lir accost ata, T. Woods. 

Limopsis insolita, Sow. sp. 

Pecten praecursor. Chapman. 

P. peroni, Tate. 

Nucula semistriata, Tate. 

Linthia (?) cjigas, McCoy sp. (probably referable to L. moora- 

boolensis, Pritchard). 

Besides these Janjukian restricted forms, another species, J/?/se^Za 

sericea, Tate, is recorded which elsewhere only occurs in the overlying 

Kalimnan series at Beaumaris, the upper beds of Muddy Creek, and in

the upper beds of the Murray Cliffs. On the other hand, only one 
species in the Corio Bay series, Capulits danieli, Crosse, is restricted 
to Balcombian elsewhere. 

This particular phase of the earthy limestone of Corio Bay is also 
found to the east of Geelong, in the outer harbor at Curlews, and its 
faunistic and lithological similarity was pointed out by Drs. Hall 
and Pritchard.* 

Curleivis. — The interpretation of the succession of the strata 
exposed in the cliffs from Clifton Springs to Curlewis is rendered 
somewhat difficult by the numerous faults which have occurred, 
and further made more obscure by landslips. By carefully piecing 
the evidence together the succession appears to be as follows. The 
lowest bed is a stratum of volcanic ash, almost black,f followed by 
a 2-ft. bed of blue clay with fossils which passes into a greenish 
sandy clay with similar forms. The argillaceous fossil beds of 
this locality have yielded several restricted Janjukian fossils J 
including Bela rvoodsi, Tate, Cypraea ovulatella, Tate, and Pecten 
praecursor. Chapman. Above this bed comes a hard polyzoal 
limestone, altogether about 6 feet thick. This limestone band 
crops out again a little way beyond the shore at low water, 
near the point of intersection of the parish boundary with the 
coast-line, as a curved or slightly undulating reef (Fig. 8).

as a fine specimen of Thamnastraea sera, a Table Cape coral. At 
the locality, Ad 14, the reef of limestone before mentioned is seen 
to have been once continuous with the limestone band in the middle 
of the cliff, and thus forms part of an anticline with a steep pitch 
of 28° to the N. 21° W. These beds dip to the west at about 15°,

there is a band of earthy limestone nodules. The Janjukian beds 
are followed by extensive ash and tuft beds of a brown and yellow 
colour, which are here seen to have slipped en bloc from above 
down to shore level (Fig. 9). To see the relation of the volcanic 
tuffs and the basalt to the beds immediately succeeding, we have to 
go eastward to within 1 mile of Clifton Springs Hotel. There we

have the bedded tuffs, agglomerate and basalt underljang the grit 
beds (Fig. 10). At the base of the grit beds there is a coarse pebbly 
deposit of quartz and metamorphosed rocks, but the bulk of the

RELATIOXSHIP|S OF THE AUSTRALIAN CAIXOZOIC SYSTEM. 

deposit is a coarse whke and irou-staiued sand, identical in appearance 
with the Kalimiwui sf.nds of the Melbourne district, and like them, 
in all probability ofiKalimnan age. The view here maintained, 
that the main volcanic series occurs above the yellow limestone and 
under the Kalimnan grits, is the same as brought forward by Mr. 
Daintree as early as 1861. A reproduction of Daintree's sketch- 
section of the cliff at Curlewis (Ad 12) is given in my paper on some 
Tertiary fossils.* On a recent \'isit to this place (shown on Quarter- 
sheet 23 sw) the section of the clifi showed a bed of tenacious blue 
clay resting on an ash bed, and above this a polyzoal limestone 
about 5 feet thick. This is surmounted by about 13 feet of basalt, 
and on this a thin layer of hill wash. 

The present occurrence of older basalt as high as the top of the 
Janjukian is unique in the experience of the \\Titer, for it generally 
occurs interbedded with or underhang the sedimentaries of that 
epoch. It further strengthens the view that the Janjukian episode 
was not onlv intermittently siibject to volcanic disturbance, as 
already found in the Anglesey district by the occurrence of tufEs 
interbedded with the sedimentaries, f b\it that the effusions did not 
cease until about Kalimnan times. 

Fyansford. — The Orphanage Hill section consists of grey clays 
passing into yellow clays. These beds probably represent an 
argillaceous phase of the Janjukian. The molluscan fauna has not 
been completely worked over, but by comparing the list of Hall 
and Pritchard, it will be seen that five species recorded by them, J 
viz., Terebratula vitreoides, T. Woods, Natica gihbosa, Hutton, Pleuro- 
toma haastii, Hutton, Limopsis insolifa, Sow. sp., and Cardita gracili- 
Gostata, T. Woods, are restricted Janjukian fossils. The remainder 
are persistent types and widely distributed forms. It is probable 
that by diagnosing the new forms to be found in this locality the 
proportion of restricted species will be raised. The palaeontological 
evidence, although leaving much to be desired, points to affinity 
with the Janjukian rather than to the Balcombian, since not one of 
the species enumerated by Hall and Pritchard is confined to Bal- 
combian. 

In my paper on " A Revision of the Species of Limopsis in the 
Tertiary Beds of Southern Australia, "§ in following the general 
usage i there placed the Orphanage Hill beds as well as the Corio 
Bay Beds in the Balcombian series. The above evidence, however, 
is sufficient proof to my mind of their affinities with the younger, 
Janjukian, series. 

Moorahool Valley and Batesford. — There is no doubt as to the 
position of these beds in the Victorian Cainozoic series, for their

faunal relationships are decidedly Janjukia:-- From Batesford, 

extending \\p tlie Mooralwol Valloy, the pol,yzoal rofk is greatly 
in evidence. This deposit at the base isfJargely composed of 
Lepiclocyclina shells, with abundant granite detritus from the 
adjoining coast. The overlying white polyzoal limestone with 
Amphistegina replacing to a large extent the Lepidocyclina 
indicates fairly deep water conditions, and a general freedom 
from terrigenous material. During this phase, therefore, the 
Janjukian sea probably represented a fjord -like aspect in which 
an arm of the sea extended up a drowned valley. In the 
neighbourhood of Steiglitz tliere are certain fault-lines which run in 
a parallel direction with the general trend of the axis of outcrop of 
the polyzoal rock, and these may have been developed as a small rift- 
valley cutting into the Ordovician ranges of the country beyond 
Maude and Steiglitz. That the conditions were not stable for a long

period is seen in the presence of argillaceous beds between the poly- 
zoal rock as at Torquay, and above the same at Waurn Ponds and 
Batesford. 

[40] 



RELATIONSHIPS OF THE AUSTRALIAN CAINOZOIC SYSTEM. 

The relationship of the Ciirlewis polyzoal rock to that ot the 
Moorabool Valley has already been pointed out. The latter locality 
has yielded a species of Cerithium (C. ])ritcJwrdi, Harris), which is 
a typical Table Cape fossil. This species also occurs at Mitchell 
River, Bairnsdale, being additional evidence for the correlation of the 
latter series with the Janjukian. Further proof of the relationship 
of the Maude beds to other Janjukian occurrences is furnished by 
the discovery in this Museum collection of Lucina planaiella, Tate, 
and Modiola pueblensis, Pritchard, in samj)les of the hard limestone 
beds collected by the Geological Survey of Victoria (WTM2). 
The former shell is a Table Cape fossil and the latter occurs at 
Torquay. 

From an examination of the sections along the river-valley 
at Maude below Mr. MacDonald's house, I was able to gain a 
clear idea of the succession of these beds (Fig. 11), which is as 
follows : — 

At the base is a bed of Ordovician slate, covered by a siliceous 
or quartzose grit, containing impressions of plant stems. This is 
followed by polyzoal rock containing, in places, pebbles of Ordovician 
slate and siliceous sandstone derived from the two underlying beds.

This polyzoal rock corresponds to the specimens marked TM3

u])oii the polyzoal rock is a bed of older basalt, and above this again 
a bed of pink limestone, thoroughly indurated and containing 
shells of littoral species, such as the Ceriihium before-namfd and 
Haliotis. Upon this lies another bed of basalt, covered by a nibbly 
polyzoal rock. 

At 100 feet below Maude township, on the road to the bridge

This basalt is only about 18 inches in thickness. Under this

before mentioned. 

The above section supports the surv^ey interpretation of these 
beds by showing that in some localities there was a second somewhat 
feeble effusion of the older basalt. It also proves the extremely 
variable thickness of the basalt and polyzoal limestone. In other 
sections not far distant the second flow is absent, as shown by the 
data given by Hall and Pritchard. 

E. — The Hamilton District. 

Two divisions of the Cainozoic beds in this area have been clearly 
defined by the work of Messrs. Tate, Dennant, Hall and Pritchard. 
These beds are revealed by the erosion of the Grange Burn and the 
Muddy Creek. The lower beds at Muddy Creek are correctly 
correlated with the Mornington beds (Balcombian) ; whilst the 
ujiper series, seen at Grange Burn and j\IacDonald"s, belong to the 
same geological horizon as the Beaumaris and Jemmy's Point beds 
(Kalimnan). 

There is, however, a third and intermediate series, which has to 
be intercalated between these beds, but which up to the present 
has been entirely overlooked, in relation to its stratigraphical 
importance and position. In all probability this was a neglected 
factor on account of its great variability, even in the same district. 
I have already postulated the middle position of the Janjukian 

[42]

or Spring Creek series in the Cainozoics ; a view indeed held by 
Messrs. Tate and Dennant, the former using the term Post- 
Eocene for these beds. If such be the case, this series should 
be either represented between the upper and lower beds in 
the Hamilton district, or should be negatively represented by an 
unconformity. That this middle series is present the following data 
will show : — 

During a visit paid to this district six years ago I was struck 
with the important development of the pink limestone with echinoids 
{Eupatagus rotundus and Linthia mooraboolensis), polyzoa, and fora- 
minifera. This rock can be followed from the bed of the Grange

remarks* as follows :— " So far as the Muddy Creek itself is con- 
cerned, all the beds consist of the clayey and calcareous layers 
alroady noticed, but in the Graiifir- Burn, fossiliforous strata of a 
different character appear, wliich have not, 1 tliink, been referred 
to by any previous geologieal writer. They form a rather friable 
rock, composed mainly of bryozoan remains, with spines of echini, 
and occasional shells, chiefly pectens, scattered through it. In 
outward appearance, it resembles almost exactly the strata on the 
Crawford River, about halfway between Muddy Creek and the 
soiith coast of Victoria. Somewhat similar strata are also found at 
Apsley, on the western boundary of Victoria, and also at Narracoorte, 
in South Australia. Those at the last-named place are described 
by Professor Tate under the name of ' polyzoal rock,' which in 
his classification of the Australian Tertiaries he has placed as ante- 
cedent in age to the Muddy Creek shell beds. In one place only

have I seen the strata in close proximity, and there the polyzoal 
rock appeared to underlie the shell beds. As, however, I was unable 
to trace actual contact, I am not prepared to speak definitely 
on the point. As I said before, this rock is nowhere ^^sible in

the Muddy Creek, but it aboiuids in the Grange Burn, not 
only above but also for a long wav below its junction with Muddy 
Creek." 

In a recent visit to the Hamilton district I was able to trace 
the Cainozoic beds in succession along both creeks, and at one spot, 
about three-quarters of a niile up the Muddy Creek, from the junction 
of the Grange Burn, was fortunate enough to find a small landslip 
revealing the polyzoal rock resting on the Clifton Bank beds (Bal- 
combian), and not underlying them as Mr. Dennant supposed (Fig. 
14). This occurrence of the limestone in Muddy Ci-eek is only 
20 chains from the well-known Clifton Bank exposure. The section 
there gives 3 feet of rubble ; foraminiferal and polyzoal limestone, 
3 feet; brown sand (fossiliferous), 20 feet; and blue clay, 
2 feet down to the water line of Muddy Creek. The two last- 
mentioned beds are comprised in the Balcombian oi Clifton Bank 
series. 

The Cainozoic strata in the Hamilton district are not perfectly 
horizontal, as Mr. Dennant believed (see loc. cit., p. 33), and conse- 
quently their irregularity does not " only arise from denudation." 
In fact, were the strata perfectly horizontal, the great thickness of 
the jjolyzoal limestone in the Grange Burn area would present an 
insm-mountable difficulty. The latest data I have collected goes 
to prove that Clifton Bank itself is on the axis of an anticline, in 
which the beds dip from 2 to 5 degrees. On the west bank of the 
Grange Burn, opposite Henty's, there are high cliffs of Lefidocyclina 
limestone surmounted by Kalimnan beds, that is, an oyster bed

cutting the Muddy Creek at MacDonald's, 1 mile south of 
Forsyth's {see sketch map Pig. 13). The effect of this fault is 
seen on the course of the Grange Burn below Forsyth's, where 
the mature stream, after coming from Hamilton and flomng 
over Kalimnan strata (Fig. 17), taking a more northerly turn, cuts 
through high banks of polyzoal limestone resting on quartz porphyry, 
thence flows to the west for 20 chains, and then southward for another

the Wannon. On the same area of uplift at Muddy Creek, starting 
from Clifton Bank, the Balcombian beds gently dip, with some 
slight undulations, towards MacDonald's, but are still seen at a

slight elevation, about 10 feet, at 40 chains east of Clifton, when 
the Muddy Creek suddenly turns north-east for 25 chains and as 
suddenly turns back to the south-east, indicating a small downthrow 
at this point, which brings the Kaliranan beds almost to creek 
level. 

From the above observations it is clear that the polyzoal rock 
of the Grange Burn directly succeeds the typical Balcombian of the 
" Lower beds. Muddy Creek." It is further proved by the occurrence 
of Linthia moorahoolensis and Lepidocydina tournouen in that lime- 
stone, that this polyzoal rock is the precise equivalent of theBatesford 
limestone. On a previous visit to this locality I had failed to fuid 
the tests of Lepidocyclina, although that genus, represented by L. 
martini occurs in the older Balcombian beds at Clifton ; but on the 
last occasion was delighted to find that a large portion of the bluf? 
(60 feet) opposite Henty's was composed of a Lepidocyclina rock 
containing species identical with those occurring at Batesford. 
At the top of the bluff west of Henty's the beds are somewhat inac- 
cessible, but at one spot, where I was accompanied by Mr. C. J. 
Gabriel, we found the rock passing into a concretionary bed with 
Kalimnan oysters and other shells (0. manubriata and Natica cunning- 
hamensis). This upper bed was 15 feet thick, so that the total 
height of the cliff from the bed of the Grange Burn is 75 feet ; whilst 
exactly opposite, the top of the Kalimnan from the creek is only 
about 45 feet. At about 30 chains up stream the same Kalimnan 
beds are only a foot or so abo^'e the bed of the creek. As to the 
succession of the beds above the polyzoal rock, the data are very 
clear along the Grange Burn, for at Pat's Gully* the top of the poly- 
zoal rock is concreted by the leaching out of the phosphoiic acid 
from the bones and coprolites of the nodules immediately overlying 
it. The nodule bed, I was at one time inclined to think, represented 
a remanie deposit of the Janjukian series, but my recent visit 
convinces me that it is the basal bed of the Kalimnan. It consists, 
as before stated, of cetacean and turtle bones, fish teeth, &c., and lies 
embedded in a stiff brown clay. The rolled ]iortion of the deposit is 
probably derived from the underlying Janjukian, since I discovered 
in a similar bed on the Muddy Creek a scutum of Lepas pritchardi, 
a fossil only found, hitherto, at Waurn Ponds and Torquay in 
undoubted Janjukian strata. The brown clay of the nodule bed 
usually contains typical Kalimnan fossils, thus proving the age 
of the deposit, and making it without doubt a conglomeratic basal 
bed. 

The most complete evidence of the succession of all our Cainozoic 
series in one locality is therefore to be gathered from the Grange 
Burn exposures. Let us, however, examine the data afforded on 
the other side of the Clifton Bank antichne. At about 35 chains

up the Muddy Creek past Clifton, at a point marked " G " on the 
sketch map (Fif;;. 13) the Balcombian fossilifcrous sandv flays appear 
a few inches above the bed of the creek, and show a dip to the east 
of 8 degrees. This is surmounted by 4 feet of polyzoal rock with 
rolled fi'agments, containing many fossils common alike to either 
Balcombian, Janjukian, or Kalimnan strata, as Area (Barbalia) 
comutilis, Cucullaea corioensis, Chania Imnellifera, Pecten sturtianus, 
Cardita delicalula, and Venus (Chione) 'projnmjua (specimens small 
atid ajjproaching the Spring Creek form V. (Ch.) halli, as well as a 
tooth of Galeoeerdo, a form which has not occuiTed lower than the 
.Janjukian. There is no doubt that whilst the Grange Burn area 
was rapidly subsiding, and given over to clear water conditions, 
on this, the east side of Clifton, the Janjukian sea was shallow, 
and subjected to currents, whilst very little deposition took place. 
Above this 4-ft. bed of polyzoal rock follows the tj'pical Kalimnan 
strata resting on a nodiUe bed, the latter containing typical fossils 
of that stage, as Glyeimeris halli, and fully developed specimens of 
Venus [Chione) propinqua. 

F. — The Mallee (Victoria) and the Mount Gamhier District, the 
Adelaide Plains, and the Eucla Basin (South Australia). 

The first two of the above localities, so far as their imdergrormd 
geology is concerned, are comprised within one area of deposition. In 
Janj ukian times that which is now the Southern Ocean extended for 
some hundreds of miles inland, forming a great gulf — the Murray 
Gulf. This gulf was bounded on the west by the great palaeozoic 
axis of which the Mount Lofty Ranges forms a part. Its deposits 
form the rocks of the Mount Gambler district, and an extension of 
the area underlies the Adelaide Plains. The fossil fauna of the latter 
area, as exemphfied in the polyzoal limestones of South Australia, is 
practically identical with the white limestone and marls of the lower 
portion of the borings in the Mallee of Victoria. The sediments 
laid down to the north of Gregory's " Primitive Moimtain Chain "* 
formed the foundation of the vast area occupied at the present day 
by the basins of the Wimmera, Murray, Darling, Murrambidgee, 
and Lachlan Rivers ; and which form the great subartesian 
basin of the Murray Gulf. In New South Wales alone this sub- 
artesian area comprises, according to C. S. Wilkinson, no less than 
22,000 square miles. 

These older deposits revealed by boring in the Mallee, Victoria, 
in South Australia and New South AVales, show, by their fossil 
contents, that they are Janjukian or Miocene in age. The only 
Cainozoic fossils found in the New South Wales bores occurred at 
Arumpo,f and one of them is strongly confirmatory of this conclusion

as to age ; for it has been identified by Mr. Robt. Etheridge as 
Trigonia semi-undulata, of the type-form which is only found 
in the Janjukian series in Victoria, in being ornamented with 
fimbriated rugae instead of ahnost plain sulcations as in the 
Balcombian variety.* In the last boring in the Mallee which 
I have examined (No. 11), there are 333 feet of white polyzoal 
limestone with occasional black cherty bands, and the bottom of 
the series was not reached. The fauna altogether showed a strong 
Aldingan and Batesfordian aspect ; both Aldinga (lower beds) and 
the Batesford Limestone being of Janjukian age. To the westward 
these bores showed a thinning-out of the deep water polyzoal facies, 
the strata being replaced by terrigenous greensands with a rich 
fish fauna. The Janjukian polyzoal limestone and greensands pass 
upwards by gradiul seqiience into Kalimnair (Lower Pliocene) shell 
marls and sands of a decided littoral aspect. The maximum thick- 
ness of this Kalimnan series is 92 feet. These are followed by 
estuarine foraminiferal sands, whicli I regard as Werrikooian 
(Upper Pliocene), similar in age to the upper beds of the 
Glenelg River. The maximum of these deposits is 163 feet. 
Pleistocene beds are indicated by barren quartz sands and grits. 
The later Pleistocene and Holocene stages are represented by 
ferruginous sands, and pinkish concretionary limestone, with 
occasional land-shells ; this series attaining a maximum thick- 
ness of 148 feet. A full report on the bores of the Mallee district, 
Victoria, is being prepared at the National Museum, ai^d will be 
published shortly. 

Another but smaller sub- artesian basin, or gulf of the Janjukian 
sea — really the remanet of a once very extensive area — is seen in 
the Eiicla Basin, north of the Great Bight, and miderlying the 
Nullarbor {= treeless) Plains. The absence of running water in this 
locality is due to the porous character of the white polyzoal limestone ; 
any moisture falling upon its surface being absorbed as by a sponge, 
to be carried away by means of underground streams. The average 
height of the Bunda Plateau, as this country roimd the Great Bight 
is called, is from 800 to 1,000 feet. 

The limestone coimtry of the southern part of Western Australia 
is of great thickness, since, according to Mr. H. Deane (in a lecture 
before the Royal Society of Victoria in 1911), a Government 
bore passed through 1,370 feet of limestone before reaching 
bed-rock. From the description it appears to be a similar lime- 
stone to that of the Eucla Basin. It is to be hoped that some 
data will be gleaned in the near future from borings and well- 
sinkings in this area during the construction of the Transcontinental 
Railway.

Summary of Conclusions. 

1. The oldest fossiliferous beds of the Cainozoics of southern 
Australia are represented by the Balcombian series (of Hall and 
Pritchard), as exemplified by the blue clays of Mornington and 
Altona Bay Coal-shaft, in Port Phillip, and the Clifton Bank series 
at Muddy Creek, Hamilton. 

2. The homotaxial equivalents of the Balcombian in European 
stratigraphy is the Oligocene (approximately Priabonian to Rupelian), 
including the fluvio-marine beds of the south of England and the 

[ 50 ] 



RELATIONSHIPS OF THE AUSTRALIAN CAINOZOIC SYSTEM. 

Isle of Wight, the Septaria Clay of Hermsdorf and Latdorf, in North 
Germany, and the Tongrian of Belgium. In Patagonia the Magel- 
lanian beds probably belong to this series, as well as the Waimangaroa 
series of New Zealand. 

3. The stage above the Balconibian is the Janjiikian (of Hall and 
Pritchard), including the Lower Aklingan (of Tate), in South Aus- 
tralia. During this period»enormous subsidence of the coastal plains 
and adjoining sea-beds took place, which resulted in the accumulation 
of a great vertical thickness of deposits ; consisting of polyzoal 
limestones, foraminiferal limestones (with Lepidocydina and Awphi- 
stegina), foraminiferal soapstone, echinoid limestones, shell marls, 
and deeper water blue muds with gasteropods. 

4. The Janjukian marine beds are, in all probability, synchronous 
with the terrestrial ironstone, sandy, or pipe-clay leaf-beds of 
Maddingley, Pitfield, Narracan, Berwick, Cobungra, Dargo, and 
Bogong. 

5. The older basalt, in exposures where fossiliferous evidence is 
available, is either contemporaneous with the Janjukian, that is, 
interbedded ; or underlying, and probably post-Balcombian ; or 
overlying the Janjukian, and pre-Kalimnan. 

6. The homotaxial equivalent of the Janjukian in Europe is the 
Miocene (approximately Aquitanian to Tortonian), and its greatest 
development approximates to the Burdigalian. In the Miocene of 
the Vienna Basin a somewhat similar fauna and flora existed, as 
seen in the accumulated banks of foraminiferal tests of Amphistegina, 
of a variety with sharp keel, found at Batesford, and by the prevalence 
of the calcareous alga Lithothamnion ranipsissimurn. 

7. The Janjukian of southern Australia is the homotaxial 
equivalent of the Patagonian beds of Santa Cruz in Patagonia ; and 
approximately of the Oamaru series of New Zealand. 

8. The Miocene age of the Janjukian receives strong support 
from the rule of maximum development in certain types of fossil 
forms of that geological epoch. As for example, in the occurrence 
of gigantic Clypeasters in the Bairnsdale beds, and the enormous 
tests of Linthia in the Murray River and Batesford beds. 

9. The occurrence of the complex-structured foraminifera, as 
Lepidocydina, of species which are elsewhere Aquitanian and Burdi- 
galian, as in southern Europe, India, Java, Sumatra, Borneo, and 
New Hebrides, further support a Miocene age for the Janjukian; 
as well as the extremely prolific growth of myriads of Amfhisteginre 
which, although found more sparingly in the lower, Balcombian 
stage, constitute whole beds of limestone, often of great thickness 
in the Janjukian series. The absence of Nummulites from the Aus- 
tralian Cainozoics is significant of their being younger than Eocene. 

10. Although the precise use of the percentage method for testing 
the relative ages of the beds is here questioned, its value in a general 
sense is not overlooked. Later researches into our molluscan fauna

and of recent dredged material are continually revealing living 
species, wliicli are also foiitul in Janjnkian or even Balcombian 
strata. 

11. The Kalirnnan of southern Australia is seen, from the 
occurrence of widely disti-ibuted fossil tyjx's, as Scaldicetus, as well 
as from its associated stratigraphical relationships, to be of Lower 
Phocene age. • 

12. The complete sequence of tlie Caiiiozoic strata occurring in 
the following order, Balcombian, Janjukian, and Kalirnnan, is .seen 
in the Hamilton District, as first shown in the present paper ; and 
also in the sequence of strata revealed in the deep boring at Sorrento. 
The Mallee bores demonstrate the gradual transition of the 
Janjukian into Kalirnnan.

NOTE ON THE PRECI&E LOCALITY OF THE TYPE 
SPECIMEN OF LEPIDOLfiNDRON AUSTRALE, McCOY. 

By Frederick Chapman, A.L.S.^ F.R.M.S., Palceontologist to the 

Nationoc Museum. 



In the " Prodromus of the "'alseontologv of Victoria," Decade 
I., 1874, p. 39, the late Sir Fredk. McCoy recorded the figured 
specimen (Holotype) of Lefidodendron australe as occurring in the 
" red and yellow micaceous carboniferous sandstone of the Avon 
River, Gippsland, 5 miles above Bushy Park. Presented by the late 
Angus McMllan." This present note is written to define the 
locality more clearly, and to accredit Mr. George Thomas Jones* 
with the discovery of the specimen. 

I am indebted to that gentleman for the following information. 
About the autumn of 1854 Mr. G. T. Jones was assisting Mr. William 
Tennant Dawson in sui-v^eying the Avon River District. Whilst 
scrutinizing the sandstone rocks of a spur dividing the Boisdale 
Plam from the Little Plain, immediately opposite the junction of 
the Avon • River and Valencia Creek, Mr. Jones discovered the 
specimen on which McCoy founded his species.

NOTES ON TESTACEA FROM THE PLEISTOCENE MARL 
OF MOWBRAY SWAMP, NORTH-WEST TASMANIA. 

By Frederick Chapman, A.L.S., F.R.M.S., Palceontologist to the 
National Museum, Melbourne. 

(Plates I., II.) 



The object of the present note is to record one or two additions 
to the Hst of mollusca given by Dr. F. Noetling*, and to describe 
the occurrence of some Ostracoda new to Tasmania. For the oppor- 
tunity of examining a sample of this marl from the Mowbray Swamp 
I am indebted to Dr. T. S. Hall, M.A., and Mr. T. Stephens, M.A. 
From this deposit the remains of a giant marsupial, the Nototherium 
tastnanicum of Mr. H. H. Scottj, were obtained, whilst Dr. Noetling 
has dealt generally with the characters of the mud deijosit. 

Quoting from Dr. Noethng (loc. cit., p. 12.5), " The Mowbray 
Swamp is about 12 miles west of Smithton, and, apparently, fills 
up a shallow depression of the surface. Probably it represents an 
old river course, which once had an outlet to the sea, but which 
subsequeiitly became blocked up by sand. At present the ' swamp ' 
is divided from the sea by a narrow strijj of sand, on which low 
dunes are rising towards the coast. There is hardly any natural 
fall from the swamp to the sea, and the vegetabilic mould, or, better 
said, peat, which fills up the depression, is completely waterlogged. 
The thiclaiess of the peat layer is not exactly known yet, but along 
the edge of the swamp, where drainage work has been extensive, 
it reaches about 25 feet to 30 feet. To me it seems very probable 
that the deepest point of the firm bottom on which the peat rests, 
is below sea level, and this would account in some way for the 
sluggishness of the fall." 

The material here examined, chiefly for ostracoda, of which, 
by the way, no species have yet been recorded, is a pale yellowish- 
grey marl, of a loose, pulverulent nature. 

The mollusca met with in the present sample are : — 

Sphcerium tasmanicum, T. Woods sp. 

Pisidium tasmanicum, T. Woods. 

Bythinella nigra, Quoy and Gaimard sp. 

Assiminea tasmanica, T. Woods.

TESTACEA FROM THE PLEISTOCENE MARL OF MOWBRAY SWAMP. 

Of these, Assiminea tasmanica and Amphi'pe'plea suhfiqualilis, 
var. neglecta, arc not recorded by Dr. Noetling. The genera As- 
siminea and Bythinella are strong indications of the pres^ncs of 
tidal influence in this swamp. This bears out Noetling's conclusions, 
since he states that " Probably it represents an old river course 
which once had an outlet to the sea." (loc. supra cit.). 

The ostracoda are new to this locality and deposit. They are 
referable to —

Sph^rium tasmanicum, T. Woods sp. 

Cyclas tasmanica, T: Woods, 1876, Proc. R. Soc, Tasm., for 
1875, p. 82. Spharium macgillivrayi, E. A. Smith, 1881, Proc. 
Linn. Soc, Lond., ZooL, vol. XVI., p. 305, pi. VII., fig. 34. 

Tenison Woods gives the length of the type shell as 9mm.; 
whilst the largest of our fossil form is only 4mm. The general 
colour of the shell, and the silvery bands mentioned by that author, 
are still visible on the fossil specimens. 

As regards the synonymy of the species, there is no doubt of the 
identity of Mr. Edgar Smith's species with the earlier S. tasmanicum. 
This conclusion is based not only on a comparison of the description 
of both shells and the figures of S. macgillivrayi, but also from an 
examination of many examples from different localities in Victoria 
and Tasmania, in the Dennant collection. Moreover, the young 
of S. tasmanicum, from Lake Connewarre, near Geelong (labelled 
in the Dennant collection as a Pisidium, is identical with our 
Pleistocene fossils from the Mowbray Swamp. Further than this, 
the Sphcerium tasmanicum is the only sjjecies knowii from Tasmania, 
and has been previously identified by Dr. Noetling from that 
locality. 

Pisidium tasmanicum, T. Woods. 

Pisidium tasmanicum, T. Woods, 1876, Proc. R. Soc, Tasm., for 
1875, p. 81. 

The length of the shell in this species, according to T. Woods, 
is from 2-4mm. The fossil examples are about 1.75mm. in length. 
In the original description of this species, there is no mention of 
other surface-ornament than the concentric striae. The present 
specimens, however, show numerous very fine radial striae crossing 
the concentrics, when viewed under the microscope by obhque 
incident light. This species has teen recorded from the same 
locality by Dr. Noetling.

The above species is the commonest mollusc in the Mowbray 
Swamp deposit. It agrees with the normal form figured by Quoy 
and Gaimard, and only slightly varies in height of spire and tumidity 
of whorls. None of the specimens show any variation towards the 
varieties legrandiana, Brazier*, or unicarinata, T. Woodsf. 

This species has been recorded by Dr. Noetling from the same 
locality as above.

A. tasmanica, T. Woods, Gatliff, 1905, Vict. Nat., vol. XXIL, 
p. 15. 

The present specimens agree with the original description by 
Tenison Woods, and, to some extent, with Petterd 's figure referred 
to above. The latter, however, does not do justice to the shell in 
showing the characteristic acute spire and sub-angularity of the 
last whorl. Some examples of the species from Port Albert, Victoria, 
which I have been enabled to examine through the kindness of Mr. 
C. J. Gabriel, have, however, a decidedly inflated outline. The figure 
of A. tasmanica given by Mr. Hedleyf is suggestive of A. brazieri, 
T. Woods, in its obtuse spire, sub-globose shell with rounded whorls, 
and colour bands. These colour bands are absent from typical 
examples of A. tasmanica, as also from our fossil specimens, which, 
when moistened, show all other colouration originally present. 

The present genus and species does not appear in Dr. Noetling's 
list. 

Genus Bulinus, Adamson, 1757. 

Note on the genus. — The common Australian sinistral pond- 
snails have been variously ascribed to Physa, Bulinus, Isidora, and 
Aflexa. Under the genus-name Bulinus, Prof. R. Tate has made

tlie following observations regarding this group* : — " The sinistral 
spiral pond-snails of Australia have been placed (incorrectly so, I 
i)(']i('vo) in the genus Physa. Tlie thick periostracuin of most of 
thcni, which in many of them is prolonged into cilia or bristles, is 
incompatible witli a largely rcflexed mantle. I have not examined 
all the Australian so-called Physre, but in no instance have I found 
those distinctions which (characterize Phym as separable from 

Bulinus The mantle margin is neither expanded 

nor digitate, in B. tenuistriata, however, it has three small serratures 
on the columella side." 

In looking into this question of the generic position of our sinistral 
pleistocene fossils the present writer has examined two typical 
living Victorian species, namely, Bulinus bullatus, Sow. sp.f, and B. 
crebreciliatus, T. Woods sp.|, with the following results : — 

The edge of the mantle in both these species is slightly reflected 
and undulate (PL I., figs. 1-3), but is not divided into numerous 
distinct angiilar tags, as in Physa (see also Pelseneer§). This 
Australian type of shell would, therefore, naturally fall into the 
genera Bulinus or Aplexa, but that the latter has a polished shell. 1 1 
The relationship was then tested by the structure of the radula. 
Aplexa in being placed with Physa in the Physidw gives no e\ndence 
of relationship with the Australian specimens I have examined. In 
Bulinus froteus. Sow. sp., the radula, on the contrary, shows its 
relationship to be %vith the Planorhidce (PL I., figs. 4ff-c), in which 
family Bulinus is placed by Pelseneer. The centrals and laterals 
of the lingual ribbon in B. fi-oteus are only slightly modified from a 
radula such as Planorbis corneus, Linne^, the three cusps being a 
constant character of the free edges of the teeth**.

It was of this species that Teiiison Woods remarked {op. supra

found in all the inland streams. It is, however, so closely allied 
to the Physa fontinalis which is diffused over Great Britain and 
Europe, that we may well doubt if it be distincttf- If not, has it

Generic Position of the .so-called Phi/sm of Australia." in which the structure of the radula is 
fully discussed. The conclu.sions arrived at are in exact agreement with the above investigation.*, 
that the Australian Phy-sae are really sinistral Limnaeids. but in their radulse nearer to Planorbis

been introduced ? ' In discussing the question of the importation 
ot this shell, on the grounds of its determination as Physa Dr 
Noetlmg* points out that the association of the remains of a giant 
marsupial goes to prove that it is indigenous. The present 
determination, that it is a distinct type from Physa, although 
outwardly resembling it, affords another instance of converaence 
of external form in different organisms. '^ 

Two minute specimens of Bidinus were also found accompanying 
the shells of B. tasmanicus in this deposit ; and these were at first 
thought to represent a new specific type, on account of the few 
whorls and exceptionally globose protoconch. On comparing the 
latter characters, however, in a series of B. tasmaniGUs a great range 
of vanabihty was found in regard to the form of the apex ; and the 
natural conclusion is, that these specimens represent the embryonic 
shells of B. tas7mnicns. This species, by the way, appears to connect 
B. nitida and B. eburnea, the former having a sliort shell with a large 
aperture ; the latter a shell with the aperture narrow, ovate, and 
shorter than the spire. 

Dr. Noetling also records this species from the above locality.

This interesting httle species is here represented by two specimens, 
typical in all points but that of size, the length of the larger example 
being 3mm., against 7mm. in Petterd's specimen. It differs from 
the European L. feregrer, Draparnaud, in the less expansive aper- 
ture and more slender form of the shell.

some having the postero-dorsal angle obtuse, as in a typical Candona, 
although the majority are more evenly rounded than usual in that 
genus. A yoimg individual is here figured, which goes to show 
the identity of the specimen from the Tweed River, New South Wales, 
figured by Dr. Brady as doubtfully belonging to this species {loc. 
svpra cit., pi. VIII., figs. 10, 11) ; since graduated examples linking 
both forms may be found here. The living examples previously 
recorded were all from New South Wales. 

The carapaces of some examples in the present series are so well 
preserved as even to show remains of the dried animal within, though 
in a powdery condition, whilst the dull yellow colour of the original 
shell is evident in most of the specimens. 

Genus Limnicythere, G. S. Brady. 

LiMNICYTHERE MOWBRAYENSIS, sp. nov. 

(Plate II., Figs. 8, a-c.) 

Description. — Carapace very minute ; measuring ■46mm. in 
length, •27mm, in greatest height (in the anterior third), and •17mm. 
in the thickness of the carapace. Seen from the side, subrectangular ; 
dorsal margin almost straight ; ventral edge with a broad median 
re-entrant angle ; anterior border roimded, trmicately so on the 
dorsal region ; posterior boldly rounded. There are three romided 
tubercles situated a short distance from the dorsal margin in the 
antero-median area, and one large, prominent tubercle near the 
middle of the ventral border directed dorsally. Anterior border 
finally crenulate ; post-ventral area with a border of minute 
aculeations. Anterior margin compressed and flange-like. Surface 
of carapace finely sculptured with a thread-like reticidated or areolate 
ornament. 

Observations. — This form, although distinct from any species 
knowai to me, approaches the type of Limnicythere inopinata, Baird 
sp.; a form common in ditches, lakes, and nmning streams in Sweden, 
Holland, and Great Britain ; and also occurring as a pleistocene 
fossil in Scotland and England. It is especially related to that 
variety of L. inopinata known as var. compressa*, which occurs in 
A\liitefield Loch, Wigtonshire, Scotland. That variety differs in 
the absence of the quadruple tuberculation and in the general 
contour of the carapace in edge ^^ew. 

Limnicythere moivhrayensis is common in the marl deposit of 
the Mowbray Swamp, Tasmania. This appears to be the first 
record of the genus Limnicythere in Australasia. 

In conclusion, my best thanks are due to IMr. C. J. Gabriel for 
valued assistance in the literature of the mollusca discussed ; to Mr. 
J. Wilson for kindly allowing me to examine his sUdes of moUuscan 
radulse ; and to Mr. W. L. May, for some valuable notes on the local 
forms.

SUMMAEY. 

1 . The sinistral molluscs generally referred to Physa, Isidora, 

and Aflexa, are here shown to belong to Bulinus, as 
already held by Prof. Tate, on account of the more or 
less entire character of the margin of the mantle, and 
V the structure of the lingual teeth which closely aj^proach 

those of Planorhis. 

2. Two species of ostracoda are newly recorded from Tas- 

mania. One of these is an entirely new species, and 
extremely interesting in view of the occurrence of 
a closely related form in Europe, found similarly in 
Pleistocene deposits. This opens up a question 
regarding the transportation of lacustrine or fluviatile 
organisms within moderately recent geological time. 

3. The conclusion as to the age of the Mowbray Swamp 

deposit is significant, for it shows that the first mar- 
supial associated \\\t\\ these remains cannot date very 
far back in Pleistocene times, as seen in the com- 
paratively fresh condition of some of the moUusca 
and the ostracoda, many of which have their original 
colour markings still preserved. This evidence gives 
further support to Dr. Noetling's previously recorded 
conclusions, based on an examination of the mollusca 
alone.
