Recorded previously from the Gault of Kent (T. R. Jones in 
Morris’ Catalogue, 2nd ed.), is common in the Chalk of France and 
England, and has been found in the Phosphatic beds of Cambridge 
(G. R. Vine) ; Reuss figures what is apparently the same form 
under the name of B. truncata, from the Bohemian Chalk. In the 
Folkestone Gault it occurs in zone xi., 55 ft. from the top, very 
rare ; 45 ft., very rare ; 6 ft., very rare.

A common form in the Chalk of France and England, but not

The earliest appearance which this form makes is in the beds of 
Chellaston (Upper Triassic? Parker and Jones); it has also been 
found in beds of Eocene, Miocene, Pliocene, and Post-pliocene ages ; 
its occurrence therefore at Folkestone supplies a link in the chain 
of records. As a recent form it occurs alike in shallow- and deep- 
water deposits. At Folkestone it is found in zone xi., 35 ft. from 
the top, rare ; 12 ft., very rare.

The Gault specimens resemble very closely those obtained from 
soundings by the 4 Challenger.’ As a recent form it affects shallow 
and deep water alike. It is also recorded from the Red Chalk of 
Speeton (Burrows, Sherborn, and Bailey). In the Gault it is found 
in zone v., very rare ; zone ix., very rare ; zone xi., 55 ft. from the 
top, very rare ; 35 ft., very rare ; 20 ft., common ; 12 ft., common ; 
6 ft., common.
