Tbe test of B. Isevis is always smooth ; and although distinctive 
names have been given to several modifications with globular, pyri- 
form, and other variously shaped segments, each with its tubular 
extensions, it is difficult to define these differences as specific. This 
form, in common with the two succeeding species herein described 
from the Gault, is invariably found in a fragmentary state. 
B. Isevis has been recorded from the Upper Chalk of Ireland 
(Wright) ; the Lower Pliocene of Austria (Bzehak) ; and as a recent 
form from Galway (Balkwill and Millett). 
t In the Gault of Folkestone this species was found in zone xi., 
50 ft. from the top, very rare ; 40 ft., very rare.
