FORAMINIFERA AND OSTRACODA. — CHAPMAN. 35 



The present specimens more nearly resemble those from 

 the South Seas described by Dr. Brady in the later reference, 

 in being more pointed posteriorly and in some cases armed 

 with a short spine. The extreme form of this series now 

 figured closely approaches P. sicula, G. S. Brady^, which 

 was described by that author also from the South Seas. 



The occurrence of this species at the exceptional depth of 

 777 fathoms is interesting. It has been previously recorded 

 from Hong Kong Harbour, 7 fathoms ; Humboldt Bay, 

 Papua, 37 fathoms ; Mauritius ; Noumea, New Caledonia ; 

 and shore gatherings, Upolu. I had it from Funafuti, South 

 Pacific, in varying depths, the deepest dredging being 200 

 fathoms. 



Station 36, east of Tasmania, 777 fathoms. Fairly 

 numerous.

This ostracod was doubtfully placed in the genus Ponto- 

 cypris by Dr. G. S. Brady on account of its carapace being 

 anteriorly depressed. He considered this character argued 

 against its being a typical pontocyprid, and thought it might 

 equally well be Bythocypris. Some examples of Pontocypris 

 attenuata, however, often show quite as much depression in 

 front as the present species. 



P. suhreniformis was dredged by the " Challenger " in 

 Simon's Bay, South Africa, 15-20 fathoms ; and from 

 Port Jackson, New South Wales, 2-10 fathoms. Dr. Egger's 

 " Gazelle " specimens came from the neighbourhood of 

 Mauritius at a depth of 411 metres. 



Station 36, east of Tasmania, 777 fathoms. One valve.
