Abstract

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.
