Type species of Tasmanian shells unrecorded in the "Census of Tasmanian Shells."
Having, in the course of my researches in the bibliography
of Australian Mollusca, noted that some specific names,
founded on Tasmanian types, are not referred to in the conchological
papers contained in recent issues of the Society's
transactions, I have thought some utility may be served by
their publication. They are not necessarily addenda to the
"Census" by the Rev. J. E. Tenison-Woods, as it remains
to be ascertained whether they are applicable or not to good
species, and if to good species then whether they have priority
or not over others already enumerated in the "Census."
This task I relegate to the author— a "Revised Census."
To the following list I have appended references to the
authorities for the specific names, and the localities of the
type-specimens
On the classificatory position and synonyms of Eatoniella rufilabrtis
The subject of this communication, which has long been
known as Bithynia, or Tatea huonensis, though another specific
name has priority of fourteen years, has hitherto been handed
about from genus to genus without finding a resting place.
For some years past I have been convinced of the incompatibility
of its reference to those families under which it has been
placed its location under Rissoininae was the first step which
led me to its present classificatory position in the genus
Eatoniella.
The main portion of this essay was written twelve years
ago, but the desire to fully work out the anatomical characters
has always been my plea for postponement of publication
now, however, the opportunity of addressing the conchologists
of Tasmania, who have most materially contributed to the
bibliography of the species, cannot be resisted, though further
study in the direction indicated is still very desirable
Notes of a critical examination of the Mollusca of the older tertiary of Tasmania, alleged to have living representatives
Mr. R. M. Johnston, in Proc. Roy. Soc, Tasmania, 1880, p.
31,gives a list of Table Cape fossils, which have been referred
to existing species. As I think that some of them have been
incorrectly identified I am desirous to give explanatory reasons
for the adoption of other names. Before doing so, I may
remark that in my presidential address to the Royal Society
of South Australia, vol. ii., p. lvi., 1879, I gave a list of 24 living species of various classes which existed in the Australian seas during Eocene and Miocene times, five of the molluscs
are included in Mr. Johnston's list; moreover, I stated that
"other fossils have been referred to living species—to Trivia Europoea, Leiostraca subulata, Lima subauriculata, Liotia
lamellosa, etc., but competent authorities have not confirmed
these identifications."
In the accompanying table I have set side by side the
Table Cape fossil species and the recent forms with which
some of them have been confounded; the names of the fossil
species represented in living creation are printed in italic
On the community of species of aquatic Pulmonate snails between Australia and Tasmania
Discussion on the classification of several shells. A revision of the nomenclature of the freshwater shells of
Australia is urgent, and I venture to offer my help in instituting
a critical comparison of the Tasmanian species, inter se
and with continental forms. For this purpose it is absolutely
necessary that the collections submitted for examination be
large and varied.
Limnaea huonensis (Tenison-Woods).
Tenison-Woods, in his paper on the freshwater shells of
Tasmania (Proc. Roy. Soc, Tasmania, for 1875), describes
four species of the genus Limnaea.
The new locality for L. huonensis is on marshy ground,
produced by the issue of freshwater from beneath the sand dunes which line the margins of the backwaters of the
estuary of the River Glenelg.
Amphipeplea papyracea.
Reference—Limnoea papyracea—Tate, Trans. Roy. Soc, S.
Aust., vol. iii., p. 103, t. 4, f. 5, 1880. Amphipeplea papyracea
—Tate, id., vol. iv., p. 140, 1881.
A. papyracea was originally described from dead shells
obtained from a dried pool at Penola, S. Australia, but a
year later it was taken alive in the reed beds, near Adelaide,
and a study of the animal brought about the new generic
appellation.
Gundlachia petterdi (Johnston). Locality-the hill-streams of the Mount Lofty
Range, near Adelaide
On the Australian pectens confounded with the New Zealand p. laticostatus. (gray)
The only species of the section Vola, inhabiting New
Zealand-waters, is generally known under Gray's name of
P. laticostatus, to which is referred P. Novae Zelandiae, Reeve,
as a synonym; but neither names should be employed,
inasmuch as the first is pre-occupied by a Lamarckian species
fossil in Pliocene Strata in Italy, and the second by another
New Zeahtnd species, established by Gray.
Eastern Australia, Tasmania, and South Australia have
each a species of Vola, which has been confounded with that
belonging to New Zealand.
The specific differences between these species may now be
detailed as follows: -
P. LATICOSTATUS is distinguished by its broad, flat, smooth
ribs with perpendicular sides, two and one-third times broader
than the flat furrows.
P. MERIDIONALIS has the ribs convexly depressed, concentrically
lamellose, and with 1, 3, or more radial sulcations;
the furrows are concave, and as wide or a little wider than
the ribs
Description of new species of mollusca of the upper eocene beds at Table Cape
Potamides pyramdiale. Locality Table Cape. R. M. Johnston (one ex.).
This species differs from the living P. ebeninium in its
relatively much greater width, in the nodulations being on the
anterior half of the whorl instead of medial, and in its coarser
spiral ornament.
Potamides semicostatum-In other respects, this species resembles.
P. pyramidale-Locality Table Cape, R. M. Johnston (six exs.).
Torcula Murrayana.Localities Table Cape. R. M. Johnston (six exs.). Very
abundant in the middle and lower beds of the River Murray
Cliffs from Overland Corner to Blanchetown; also at Muddy
Creek, Corio Bay, and Schnapper Point (R.T.).
Turritella tristira. Locality Table Cape. R. M. Johnston (one example).
Leiostraca Johnstoniana-Syn.—Eulimella subulata, Tenison-Woods (non Mont,).
Localities Table Cape. R. M. Johnston. River Murray
Cliffs, near Morgan, S. Aust.; Muddy Creek, Victoria. R.
Tate.
Cyclichna woodsii.
Syn.—C. arachis. Tenison-Woods (non Quoy).
The above definition is drawn from a Table Cape specimen
identical with that which Tenison-Woods referred to the
living species C. arachis of Quoy.
Chamostrea crassa. Locality Table Cape. R. M. Johnston (two examples).
Corbula ephamilla.Localities Table Cape. R. M. Johnston. Abundant in
the calciferous sand-rock of the River Murray Cliffs, near
Morgan, and in the contemporaneous deposits at Muddy Creek.
(R.T).
Lucina planatella-The fossil has no close ally among living congeners.
Chione (Timoclea) hormophora.Locality Table Cape. R. M. Johnston (a left valve).
Chione (Tinoclea) dimorphophylla -Length, 58; breadth, 45; thickness, 32 millimetres.
Lima jeffretsiana-Syn.—Lima subauriculata, Tenison-Woods (non Mont.).Localities Table Cape. R. M. Johnston. Yorke Peninsula, Aldinga, River Murray Cliffs, Muddy Creek and Schnapper Point, Hobson's Bay. E. Tate.
The majority of the new species have considerable analogy
with recent congeners; but especial interest attaches to the
existence in a fossil state of the genus Chamostrea, hitherto
represented by a single species proper to South-eastern and
Southern Australia and to Tasmania
On some Australian slugs, chiefly Tasmanian
Slugs have long been known to inhabit various parts of the
Australian colonies, and their existence is, year by year,
becoming more and more unpleasantly familiar to the gardener
and floriculturist. The naturalist has, however, paid
little attention to them
