FOEAMINIFEEA OF THE KEEIMBA AECHIFELAGO. 617 



owing to its method of growth and the paucity of suitable material for examination, has 

 escaped observation. 



The occurrence of this genus — hitherto known only from the Torres Straits and 

 tropical Pacific — at Kerimba is very noteworthy.

2 Stations. 



One minute spherical specimen at Stn. 3, characterized by a virtual absence of 

 papillse, and- another at Stn. 13. The test is constructed of extremely fine calcareous 

 particles, neatly agglutinated. We have met with similar specimens from Cuba. 

 In colour and general appearance the specimens are perhaps more closely referable to 

 T. albicans Brady, but as the distinguishing feature of that species, according to Brady, 

 is the thick shell-wall contrasting with the thin wall of T. papillata, it seems desirable 

 to refer the Kerimba specimens to T. pafillata. 



HiPPOCREPiNA Parker. 



143. Hippocrepina oviformis, sp. n. (Pi. XLVI. figs. 23, 24.) 



1 Station. 



Test free, minute, oval, slightly produced at the oral extremity. Walls thick, formed 

 of finely agglutinated, very minute sand-grains, light grey in colour. Surface smooth. 

 Aperture a simple circular opening on a slightly produced terminal neck. The walls 

 of this species are so thick and densely constructed that practically no structure is 

 visible when the specimens are mounted in balsam. 



Very rare at Stn. % B, the only locality at which it was observed. 



Breadth "2 mm. Length "27 mm.
