18 AUSTRALASIAN ANTARCTIC EXPEDITION, 
and were obtained during the Subantarctic Cruise between the south-east of Tasmania 
and Macquarie Island. Several valves show a blunt spine at the postero-ventral angle 
as in Brady’s figured example from the South Seas. 
Occurrence—No. 58 (11th December, 1912), 1,180 fathoms. No. 59 (12th Decem- 
ber, 1912), 1,320 fathoms. No. 60 (12th December, 1912), 1,300 fathoms.

Pontocypris davidiana Chapman, 1910, Journ. Linn. Soc. Lond., Zool., vol. XXX, 
p. 427, pl. LVI, figs. 17a, b. 
Observations.—This distinct species has only been observed previously at one 
locality, at Funafuti, Sta. 13, 1,050 fathoms. The present example is a typical right 
valve. 
Occurrence.—No. 60 (12th December, 1912), 1,300 fathoms.

Observations —This is another of the species hitherto found only in shallow water, 
with the exception of an occurrence at Funafuti in 1,050 fathoms. The present examples 
are from dredgings round Tasmania. It was formerly recorded from the Ross Sea by the 
writer, from 110 fathoms. 
Occurrence.—No. 59 (12th December, 1912), 1,320 fathoms. No. 60 (12th Decem-

pl. I, figs. 5a-d. 
Observations —P. simplex appears to have occurred only once before, off Ascension 
Island, in 7 fathoms. It is here noted from the great depth of 1,300 fathoms, west of 
Tasmania. 
One right valve. 
Occurrence.—No. 60 (12th December, 1912), 1,300 fathoms.
