OSTRACODA—CHAPMAN, 29 
Observations.—This species also occurred in the Magellan Straits, in 55 fathoms. 
It has since been found fossil in Miocene to Ploicene strata in the Mallee of Victoria. 
The specimens here found-at the great depth of 1,300 fathoms are smaller in size than 
usual. 
Occurrence—No. 59 (12th December, 1912), 1,320 fathoms. No. 60 (12th 
December, 1912), 1,300 fathoms.

Observations —It is interesting to meet with this northern and levantine species 
in the present sounding, Hast of Tasmania. The form resembles C. kerguelenensis Brady 
but is of thinner build, more tumid in form and with a finer pitted surface ornament. 
Occurrence.—No. 58 (11th December, 1912), 1,180 fathoms.

Cythere subrufa G. 8. Brady, 1880, Rep. Chall. Zool., vol. I, pt. III, p. 81, pl. XX, 
figs. 3a-f. 
Observations —This species is fairly common in the samples mentioned below. 
Previously recorded from Balfour Bay, Kerguelen Island, and off Prince Edward’s 
Island; it is thus confined to the Southern Ocean. Some examples closely approach 
C. wyville-thomson by the elevation of the ventral ridge and the tapering of the 
posterior extremity. 
Occurrence—No. 28 (14th February, 1912), 160 fathoms. No. 13 (14th 
November, 1912), 1,940 fathoms. No. 30 (15th February, 1912), 182 fathoms. No. 31 
(15th February, 1912), 220 fathoms. No. 67 (29th December, 1912), 1,670 fathoms. 
No. 92 (22nd November, 1913), 2,400 fathoms..

Observations.—This species has occurred at Torres Strait, at Heard and Ker- 
guelen Islands in the Southern Ocean, and on the West Coast of Africa. It occurs 
fossil (Miocene) in the Mallee Bores of Victoria, and these ancient representatives are 
in every way typical of the species,
