This species appears to bo of common occurrence in Jurassic 
strata (Jones, Parker, Crick and Skerborn) ; and it has been described 
from the Middle Hils formation and the Speeton Clay of North 
Germany (Eeuss). The previous records for the Gault are Meux’s 
well-boring, London (C. Moore), and Folkestone (.Rupert Jones in 
Topley’s Memoir on the Weald). It is somewhat striking that this 
form occurs only in the fossil state and never above or below deposits 
of secondary age. 
P. caracolla , in common with others of the “ elegans ” type, 
exhibits the secondary slit-like aperture. 
In the Gault of Folkestone P. caracolla was found in zone i., 
spec, a, very rare ; zone i., spec, h, very rare ; zone ii., spec, c, frequent ; 
zone iii., common ; zone iv., common ; zone v., rare ; zone vi., very 
rare ; zone viii., very rare ; zone ix., frequent.

P. reticulata is another of the forms which has been relegated to 
Terquem’s quasi-genus Epistornina. The Gault specimens show the 
secondary aperture in most of the examples examined. 
The geological range of this species is very similar to that of the 
preceding. It has been described from the Ornatus clays of Eussia 
(Uhlig) ; from the Millettianus- clay at the base of the Albian group 
of North Germany (Eeuss) ; and from the Lower Marl bed, Navesink 
formation, of New Jersey (Bagg). 
P. reticulata was found in the Gault of Folkestone in zone i., 
spec, h, very rare : zone ii., spec, c, very rare : zone xi., 55 ft. from the 
top, very rare. 
Pulvinulina Carpenteri Eeuss sp., plate I. figs. 11 a-c. 
Piotalia Carpenteri Eeuss, 1862, Sitzungsb. d. k. Ak. Wiss. Wien, 
vol. xlvi. Abth. i. p. 94, pi. xiii. figs. 6 a-c. 
The graduations from the carinate vaiiety of Pulvinulina elegans 
to the ornate forms of the group culminate in P. spinulifera , and the 
present species occupies an intermediate position, with its finely serrate 
or prickly peripheral edge. The secondary aperture is also present 
in this species, and is well shown in plate I. figs. 11 h and c. 
P. Carpenteri appears to be entirely restricted to the Gault forma- 
tion, having been recorded from this horizon by Eeuss and Rupert 
J ones. * 
In my own collection from Folkestone it occurs in zone ii., spec, c , 
rare ; zone iv., frequent ; zone v. very common ; zone vi., common ; 
zone vii., rare : zone viii., frequent : zone ix., common.
