This is a rare and widely scattered form in the Gault. Mr. 
Joseph Wright records this form as abundant in the Chalk of the 
North of Ireland. It has also been found fossil in the principal 
Tertiary beds. Zone iv., very rare ; zone v., very rare ; zone xi., 
12 ft. from the top, very rare.

In the Gault this form occurs very sparingly ; it is separated 
from T. agglutinans on account of its broad and compressed form, 
and from the other Textularise for the coarseness of its test. It has 
been recorded trorn the Red Chalk of Speeton (Burrows, Sherborn, 
and Bailey). Zone xi., 45 ft. from the top, very rare ; 12 ft., rare.

This form is scarce in the Gault and must not be confused with 
Valvulina conic a P. and J., which it very much resembles on 
first acquaintance. It has been previously recorded as a Cretaceous 
species, and also from the Red Chalk of Speeton (Burrows, Sherborn, 
and Bailey). Zone ii., specimen a, rare ; zone xi., 20 ft. from the 
top, very rare.

This is also a characteristic Cretaceous Foraminifer ; Reuss 
records it from the Middle Hils formation of Northern Germany ; 
and Messrs. Burrows, Sherborn, and Bailey note it from the Red Chalk
