The Gault specimens agree very closely with the figures given by 
Dr. Brady. Regarding the peculiar shell-structure shown in Dr. 
Brady’s Report, p. 516, fig. 15 a, b, it has been impossible to give 
sufficient material for a drawing, from the Gault specimens, owing to 
their rarity ; from a shell mounted in Canada balsam, however, some 
evidence has been obtained, which supports the idea of the existence 
of the same structure as is seen in the recent specimens. Dr. Brady’s 
specimens were obtained from one locality only, off Bermuda, at 
a depth of 435 fathoms. It is found in the Gault in zone iii., very 
rare ; zone xi., 25 ft. from the top, rare. 
Nodosaria sceptrum Reuss, plate IX. fig. 9. 
Nodosaria sceptrum Reuss, 1862, Sitzungsb. d. k. Ak. Wiss. 
Wien, vol. xlvi. p. 37, plate ii. fig. 3. 
This species was figured by Reuss from specimens obtained from 
the Upper Hils formation of North Germany. This form has 
appeared in one instance only in the Folkestone Gault, near the base 
of the beds ; and it is interesting to note that, while Reuss’s specimens 
are large and fully developed, and have come from beds older than 
the Gault, the specimen from the latter formation is small and ill- 
developed. It occurs in the Gault in zone i., specimen b, one 
specimen.* 
Nodosaria internotata , plate IX. fig. 10. 
Shell consisting of five more or less inflated chambers, the last 
much larger than the others. The surface ornamented with delicate 
costae, between which are secondary costulae consisting of much inter- 
rupted lines and dots. Length 1 /48 to 1 /30 in. Found in zone i., 
specimen b, very rare ; zone iii., very rare ; zone v., very rare ; zone 
xi., 50 ft. from the top, very rare ; 45 ft., rare ; 35 ft., very rare ; 
30 ft., very rare. 
Nodosaria ( D .) tubifera Reuss, plate IX. fig. 11. 
Nodosaria tubifera Reuss, 1862, Sitzungsb. d. k. Ak. Wiss. 
Wien, vol. xlvi. p. 37, plate ii. fig. 4. 
This form was figured by Reuss from specimens obtained from the 
Hils formation of North Germany. The Folkestone specimens are 
sometimes slightly curved in the line of growth ; and the specimen 
figured shows a larger number of costae than is usually seen, though 
the form of the shell is very typical. It is found in zone i., 
specimen b, frequent ; zone iii., frequent ; zone iv., very rare ; 
zone v., very rare; zone vi., rare; zone viii., very rare; zone xi., 
55 ft. from the top, rare ; 50 ft., very rare ; 45 ft., frequent ; 40 ft., 
frequent ; 35 ft., frequent ; 20 ft., very rare. 
* This specimen was unfortunately destroyed after the drawing was made.
