438 ME. F. CHAPMAN ON DEEP-SEA FOKAMINIFERA 



Length 1*04 mm. ; height '458 mm.; thickness of carapace, including 

 the spines, '75 mm. 



Affinities. — This species somewhat resembles B. armata, Chapman'^, but 

 there is no dorsal tubercle in the latter, whilst B. armata shows a costation 

 o£ the ventral area which B. tuberculata does not. 



Occurrence. — Sta. 20, 1215 £ms.

This species is very variable, as pointed out by Dr. Brady, who regards all 

 the Northern and Southern forms as belonging to one type. The distribution 

 is very wide, extending round the shores of the British Islands, the N. 

 Atlantic, the Mediterranean, the S. Atlantic, and the Southern Oceans. The 

 Funafuti examples are comparable with the ' Challenger ' specimens, and 

 are not uncommon in the deep dredgings named below. Egger obtained it 

 off the Australian Coast at 357 metres. 



Occurrence.— ^i^. 13, 1050 fms. ; 20, 1215 fms. 



Pseudocythere funafutiensis, sp. nov. (Plate 57. fig. 28.) 



Description. — Carapace compressed, elongate ; seen from the side, narrow, 

 subelliptical, higher in the posterior half, height less than one-third of the 

 length ; anterior extremity pointed and truncately rounded towards the 

 ventral angle ; dorsal line slightly curved ; ventral margin nearly straight in 

 the middle, but truncated and excavated towards the posterior prolongation 

 which lies close to the postero-dorsal angle. Surface finely lineate longi- 

 tudinally over the whole length of the shell. Edge view narrow-elliptical, 

 strongly compressed at the extremities. 



Length 1'02 mm. ; height 'o mm. 



Afiuities. — The surface-ornament of this species is similar to that of 

 F. fuegiensis, Brady t, but in the latter it is confined to the extremities of the 

 valve. The narrow form and peculiar outline of our example show it to be 

 distinct from that species. 



Occurrence. — Sta. 13, 1050 fms.
