24 AUSTRALASIAN ANTARCTIC EXPEDITION. 
Observations —A single left valve was found at the great depth of 1,300 fathoms, 
south-west of Tasmania. It has lately occurred in the Miocene of Victoria. 
Occurrence.—No. 60 (12th December, 1912), 1,300 fathoms. 
CYTHERE CRISTATELLA CG’. S. Brady, Plate XXI, figs. 7, 7a. 
Cythere cristatella, G. 8S. Brady, 1880, Rep. Chall. Zool., vol. I, pt. III, p, 90, 
pl. XIX, figs. 6a-d. 
Observations —C. cristatella was formerly recorded from Booby Island, Torres 
Strait. 
It is possible that the valve figured in Rep. Chall. Zool., vol. I, pt. III, pl. XV, 
figs. 7e-h, and doubtfully referred to Cythere audei, may belong to C. cristatella, as 
several examples closely resembling it, but showing affinities with the latter species, 
occur in the present series. 
Occurrence.—No. 28 (14th February, 1912), 160 fathoms. No. 31 (15th Feb- 
ruary, 1912), 220 fathoms. No. 59 (12th December, 1912), 1,320 fathoms. No. 110 
(21st December, 1913), 157 fathoms. 
CYTHERE DASYDERMA G. S. Brady. 
Cythere dasyderma G. 8. Brady, 1880, Rep. Chall. Zool., vol. I, pt. III, p. 105, 
pl. XVII, figs. 4a-f; pl. XVIII, figs. 4a-f. Chapman, 1910, Journ. Linn. Soc. Lond. 
Zool., vol. XXX, p. 432. Idem, 1914, Proc. R. Soc. Vict., vol. XXVII (N.S.), pt. L 
p- 34, pl. VI. fig. 10. 
Observations —This truly deep-sea ostracod has, curiously enough, been found 
fossil in Miocene beds in the Mallee bores in Victoria. Those occurring here are quite 
typical. 
Occurrence.—No. 11 (13th November, 1912), 1,475 fathoms. No. 12 (14th 
November, 1912), 2,083 fathoms. No. 58 (11th December, 1912), 1,180 fathoms. 
No. 59 (12th December, 1912), 1,320 fathoms. No. 60 (12th December, 1912), 1,300 
fathoms. No. 67 (29th December, 1912), 1,670 fathoms. No. 74 (5th January, 1913), 
1,900 fathoms. No. 92 (22nd November, 1913), 2,400 fathoms. 
CYTHERE DAVISI Chapman. 
Cythere davisi Chapman, 1916, Brit. Ant. Exped., 1907-9, Geol., vol. Il, p. 72, 
pl. VI, figs. 46a-c. 
Observations.—This species belongs to the C. wyville-thomsoni group, and is 
distinguished by the rounded posterior extremity, the thicker carapace and feeble 
surface reticulation. 
It was dredged by the “ Nimrod” in 121 and 225 fathoms. 
Occurrence.—Additional sample (3rd September, 1912), 706 fathoms.
