 Description.— Test elongate, usuaUy somewhat arcuate, composed 

 of a few elliptical chambers in adult specimens, three to five m num- 

 ber; wall smooth or occasionally with a few very delicate hispid 

 spines; wall transparent, both ends broadly rounded, smooth; aper- 

 ture a simple opening without iicck. 

 Length 0.50—1 mm. 



Distribution.— Br?idy recorded specimens under this name from 

 three stations in deep water in the Atlantic; in the North Atlantic in 

 1,215 fathoms (2,222 meters), in the South Atlantic, m midocean 

 in 1,990 and 2,220 fathoms (3,640 and 4,061 meters), and in very 

 shallow water, 6 fathoms (11 meters), off the Falkland Islands. 

 Egger records it off Western Africa; Pearcey records it from a sta- 

 tion in 1,998 fathoms (3,654 meters) in the middle South Atlantic, 

 and in 2^ fathoms (4 meters) , Stanley Harbor, Falkland Islands. It 

 has been recorded a number of times off the coast of the British 

 Isles, the deepest stations those given by Wright off the southwest 

 of Ireland, very rare at 750 and 1,020 fathoms (1,370 and 1,866 me- 

 ters) . The only specimens that I have had which can be referred to 

 this species are from an Albatross station south of Nantucket.
