BULIMINELLA SIJBTERES (H. B. Brady), variety. 



riate 22, fig. 6. 



At a single station, Albatross D2761, off the east coast of South 

 America, in 818 fathoms (1,483 meters), a specimen of this species 

 was obtained which was thin and translucent and liad the wall 

 ornamented ])y numerous more opaque areas, giving a very ornate 

 appearance to the test. Whether this is a constant feature or not 

 the lack of specimens makes it impossible to determine. 



Buliminella suhteres, variety — material examined.

Description. — Test elongate, subc3^1indrical, the ends broadly 

 rounded; chambers few, irregularly spiral, slightly inflated, last- 

 formed one elongate; sutures distinct, but very slightly depressed; 

 wall thin and translucent, finely perforate; aperture an elongate, 

 nearly straight slit, vertical, on the inner face of the terminal chamber 

 extending in from the margin. 



Length 0.4-0.6 mm. 



Distribution. — Brady originally had this species from three At- 

 lantic stations, off Gomera, Canaries, 620 fathoms (1,140 meters), 

 off the Cape de Verde Islands, 1,070 fathoms (1,957 meters), and off 

 Pernambuco, Brazil, in 675 fathoms (1,234 meters). 



Elsewhere the species is recorded from West Africa in 677 meters 

 (369 fathoms) by Egger, although his figure is so poor that it can 

 not be made out whether it should really be referred to this species 

 or not. It is also recorded from the Arabian Sea (Chapman), Malay 

 Archipelago (Millett), and off the east coast of Australia (Side- 

 bottom). 



It is allied to B. subteres Brady, but is very distinct in its general 

 form and apertural characters.
