Occurrence. — Bore 3, 201-220 feet (Kalimnan or Janjukian). 

 Bore 8, 210-219 feet (Kalimnan or Janjukian). Bore 10. :510-320 

 feet (Kalimnan or Janjukian). Bore 11, 342-349 feet; 438-440 

 feet; 440-442 feet; 442-444 feet; 446-448 feet; 457-458 feet; 540- 

 542 feet; 542-544 feet; 544-546 feet; 546-548 feet; 548-550 feet;

 Zool., vol. i., pt. iii., p. 83, pi. xvi., figs. la-d. ; 2a-d.

Observations. ^T\\e " Challenger " examples came from Bass 

 Strait, and off Honolulu. Egger obtained it between Fiji and 

 Samoa, and from the Western Australian coast. 



This is its first occurrence in the fossil state. It occurs in the 

 bores in the Kalimnan (Lower Pliocene) strata, or even below that 

 series. Like several other species of ostracoda occurring in these 

 borings, the form persists in the present Bass Strait fauna, not 

 many miles removed from the site of the old Murray Gulf. 



Occurrence. — Bore 8, 210-219 feet (Kalimnan or Janjukian). 

 Bore 11, 170-175 feet; 199-209 feet; 219-260 feet (Kalimnan). 



Cythere scabrocuneata, G. S. Brady. (Plate VIII., Fig. 25).

 vol. i., pt. iii., p. 103, pi. xvii., figs. 5r/-/.- j)l. .xxiii., 

 figs. '2a-c. 



Observations. — The figured specimen is a ([uadrate and coarsely 

 papillate variety of the above species, but it is impossible' to 

 separate it from its associated typical examples from the same 

 series, some of which are identical with the living forms. This is 

 another species still living in Bass Strait, having remained per- 

 sistent in nearly the same area from Janjukian (Miocene) times. It 

 has also been recorded from recent dredgings in the Inland Sea, 

 Japan, and in Wellington Harbour, New Zeal-and. 



Occurrence.— ^OYQ 11. 430-432 feet; 442-444 feet; 444-446 feet; 

 446-448 feet; 457-458 feet; 544-546 feet; 552-554 feet (Janjukian).
