This form, the Gault variety of which is perhaps more nearly 
represented by Reuss’s figure of B. laxa, is met with in rocks as old 
as the Permian. Reuss’s specimen was found in the Septaria-clay 
of Pietzpuhl. It is found in the Gault in fragments only in zone viii., 
rare ; zone x., frequent ; zone xi., 45 ft. from the top, very rare ; 
6 ft., very rare.

This very distinct form is met with in the Gault in zone i., 
specimen b, frequent ; zone ii., specimen b, very rare ; zone x., very 
rare ; zone xi., 50 ft. from the top, common ; 30 ft., very rare ; 
25 ft. frequent ; 12 ft., very rare.

This variety is distinguished from the type form (V. soluta) by 
having less constricted sutures and elliptical-shaped chambers. It was 
described by Reuss from specimens found in the Senonian of Westphalia. 
One example only from the Folkestone Gault was found in zone viii. 
Nodosaria (D.) soluta Reuss, var. pulchella, plate VIII. fig. 28. 
This variety differs from the typical B. soluta in having a more 
slender and tapering shell ; the commencing segments are spherical 
and closely conjoined, and in subsequent growth approach the type 
form in being separated by the sutural constrictions. Length 1 /34 
in. It is found in the Gault in zone ix., rare ; zone xi., 40 ft. from 
the top, very rare.
