FORAMINIFERA AND OSTRACODA. — CHAPMAN. 41 



A single valve of this rare species occurs in the present 

 soundings. It was originally described from " Challenger " 

 examples, from a dredging in 150 fathoms off the Cape of 

 Good Hope. 



Station 36, east of Tasmania. 777 fathoms. A left valve.

C. dictyon is a generally deep water species, but it occasion- 

 ally occurs at moderate depths. The specimens here found in 

 the sounding at 100 fathoms are most like those Avhich I have 

 described as Miocene fossils in the polyzoal rock in the Mallee 

 Borings of Victoria. 



Station 36, east of Tasmania, 777 fathoms. Specimens 

 typical, common. 



Forty miles south of Cape Wiles, 100 fathoms. Specimens 

 well grown and abmidant ; ornament comparatively stronger 

 than in deep water forms. 



Cythere rovEOLAT.\, G. S. Brady. 



Cythere foveolata, G. S. Brady, Chall. Rep., Zool.,i.,pt. iii., 

 1880, p. 75, pi. xiii., figs. 5a-h. 



The " Challenger " examples were obtained off Christmas 

 Harbour, Kerguelen Island, at 120 fathoms ; and off Heard 

 Island at 75 fathoms. 



C. foveolata has been recently identified by the writer from 

 Raised Beaches in the Antarctic. 



This species forms a central type with several varieties or 

 allied forms as C. moseleyi, G.S.B., and C. falklandi, G.S.B. 



The present example has the surface reticulations less 

 strongly developed than usual, otherwise it is typical. 



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



Cythere impluta, G. S. Brady.

The present specimens most nearly resemble the figures 

 on plate xxvi. of Dr. Brady's Report, which represent ex- 

 amples from both Tristan d'Acunha and the Falkland 

 Islands. The type of shell figured on plate xvi. of the same
