26 AUSTRALASIAN ANTARCTIC EXPEDITION. 
Observations —This species dates from the Miocene, it having occurred in the 
Mallee borings in Victoria. It is a widely distributed form. 
Occurrence—No. 60 (12th December, 1912), 1,300 fathoms. One valve.

Observations —The single valve occurring here is remarkably like that figured by 
the writer from the Miocene-Pliocene of the Mallee Bores. C. militaris is only found 
in the Southern hemisphere and has hitherto been noted from shallow water. The 
fossil occurrence is in strata which indicate deeper water subjected to current action. 
Occurrence.—No. 149 (18th February, 1914), 2,600 fathoms.

Sea. Brit. Ant. Exped., Geol., vol. II, pp. 50, 73, pl. VI, fig. 2. 
Observations —This species was not uncommon in previous soundings in the 
Antarctic. It dates from Miocene times in Victoria, and was also recorded by Dr. G. 8. 
Brady from late Tertiary deposits in the Murray Flats of South Australia. 
Occurrence.—No. 29 (14th February, 1912), 125 fathoms. No. 60 (12th Decem- 
ber, 1912), 1,300 fathoms.

fig. 20. 
Observations.—The present record extends the range of the species to the 
Antarctic Ice-barrier. It was previously known from Kerguelen Island and the 
Tasmanian area, as well as from West Africa, the Mauritius and the Admiralty Islands. 
Fossil examples were found in the Mallee Bores in Victoria, in Miocene beds. 
Occurrence—No. 31 (15th February, 1912), 220 fathoms. No. 11 (13th 
November, 1912), 1,475 fathoms. No. 59 (12th December, 1912), 1,320 fathoms.
