pl. XI, XIV, figs. la, b. Chapman, 1902, Journ. Linn. Soc. Lond. Zool., vol. XXVIII, 
p- 424. 
Observations —The localities for this species are very widely separated, viz., 
Inland Sea, Japan (15 fathoms); Funafuti, Pacific (beach sand and 50-60 fathoms) ; 
and the present occurrence, south-west of Tasmania (1,300 and 1,320 fathoms). The 
example from No. 59 is very typical; those of No. 60 are almost reticulate in surface 
ornament. 
Occurrence.—No. 59 (12th December, 1912), 1,320 fathoms. No. 60 (12th 
December, 1912), 1,300 fathoms.

Observations.—In the living condition this species appears to be restricted to 
Australian seas. As a fossil it occurs from Oligocene times onward in Europe, and in 
the Miocene of the Mallee, Victoria. 
The present specimens, from the south-west coast of Tasmania are all typical 
valves. The depths now recorded are exceptional, as the deepest hitherto was 777 
fathoms. 
Occurrence.—No. 59 (12th December, 1912), 1,320 fathoms. No. 60 (12th 
December, 1912), 1,300 fathoms.
