Dredged alive at 15 fathoms in Backstairs Passage, 4; 
at 16, 17, 18, 20, and 22 fathoms, very many; at 30 fathoms, 
off Corney Point, Spencer Gulf, 17; at 40 fathoms, off Beach- 
port, 3 alive and 11] dead, all small; at 55 fathoms, off Cape 
Borda, 1 alive 11 dead, all small, and at 60 fathoms, 10 
dead,*small; at 90 fathoms, off Cape Jaffa, 2 minute, dead ; 
at 110 fathoms, off Beachport, 4 minute and 13 small, dead, 
and at 150 fathoms, 3 minute. It occurs in both our gulfs 
and both straits, and has its habitat from 15 to 30 fathoms. 
It may occur in shallower waters (in which I have dredged 
very seldom), as it has been taken in Port Jackson by 
Brazier in 3 and 7 fathoms. The “Challenger” took it 
abundantly in 35 to 40 fathoms. Beyond that depth only 
7 Very immature specimens have been obtained by me.

Shell thin-walled, translucent, oval, widest a little in

the dorsal, convex longitudinally, especially towards the 
beak, transversely convex, slightly centrally flattened ; 
lateral edges slightly concave, front slightly convex. Beak 
very short, obliquely truncated. FForamen of moderate size, 
incomplete, the anterior eighth formed by the back of the 
dorsal valve, bevelled from the outer to the inner edge. 
Deltidial plates narrow triangular, not meeting in the middle 
line. Teeth small, projecting inwards and backwards. Dor- 
sal valve convex longitudinally and transversely, slightly 
prominent centrally, and sloping at the sides; lateral edges 
convex, anterior edge slightly concave. Hinge line narrow
