Characters. — More or less ovate (obovate) and tapering; the chambers extend 

 backwards with a free edge (marginate), which is creuate, serrate, or prickly. 



Occurrence. — Bulimina marginata has a very wide geographical and bathy- 

 metrical range. In the Distribution Tables appended to the ' Challenger' Report 

 it is recorded from the South and North Pacific, 345 — 675 fathoms ; between 

 Prince-Edward Island and Kerguelen, 1375 fathoms; off the coast of New Guinea, 

 1070 fath. ; off the west coast of Patagonia, 40 — 175 fath., W. Australia (' Gazelle '). 



The earliest recorded geological occurrence of this species appears to be in the 

 Miocene of Italy. It has also been found in the Pliocene of St. Erth, and in the 

 Pleistocene of Norway, Scotland, and Ireland. So far as the Crag is concerned,
