The specimens found in the Gault are in a fragmentary condition, 
and with the superficial processes evidently worn down close to the 
surface of the shell. This species has been recorded from the Lias of 
England (Brady, Walford) ; the Chalk of Ireland (Wright) ; the 
Phosphatic Chalk of Taplow (Chapman) ; and from numerous beds 
in the Tertiary and Post- tertiary formations. It occurs in zone i., 
specimen b , frequent ; zone iv., common ; zone v., frequent ; zone vii., 
frequent ; zone xi., 45 ft. from the top, frequent. 
Nodosaria perpusilla, plate IX. fig. 6. 
Shell slightly tapering to the commencement, cylindrical, and 
consisting of a straight series of about seven chambers, the breadth of 
each chamber nearly equal to the length ; the sutures distinctly 
marked ; the aboral end mucronate. Surface of the shell ornamented 
with from six to seven delicate longitudinal costae. Length 1/70 in. 
This form is the smallest of the Gault Nodosariae. It is found in 
zone iii., rare ; zone v., very rare ; zone xi., 50 ft. from the top, very 
rare. 
Nodosaria bambusa, plate IX. fig. 7. 
Shell consisting of subcylindrical, or slightly inflated, segments, 
four times longer than their breadth ; the divisions between the 
chambers seen only as translucent sub-surface markings. The surface 
of the test decorated with fine and numerous longitudinal costae, which 
are slightly diverted or twisted towards one side. Found in fragments 
only. Average length of chambers 1/33 in. This elegant species 
occurs in the Gault in zone v., rare; zone xi., 55 ft. from the top, 
very rare.
