striated obliquely, somewhat like that of V. gaultina. V. striolata 
was recorded from the Flammenmergel of North Germany by 
von Beuss. 
One specimen only was found in zone x. of the Gault at Folke- 
stone.

ser. 3, yob i. No. 5, p. 38, plate i. fig. 21 a-d. 
Some of the Vaginulinse with striate costae from the Gault, on 
careful observation are seen to possess an initial chamber which is not 
exactly in line with the rest of the shell, that is not terminal, but 
placed towards the inner side of the usually incurved commencement ; 
the specimens showing this variation from the characters found in 
V. gaultina have been named V. comitina by M. Berthelin. The 
initial chamber is also smaller in this form, and, though more or less 
salient, is deeply set, and therefore scarcely seen when the edge view 
is taken. The costal ridges are not so conspicuously striate as in 
V. gaultina. 
Besides occurring in the Gault, V. comitina is found in the “ Chalk 
detritus ” of Charing ; and some of the specimens I have met with 
from the latter material are exceedingly beautiful and extreme varieties 
of the species. 
It is found in the Gault at Folkestone in zone x., frequent ; 
zone xi., 40 ft. from the top, very rare ; 30 ft., very rare ; 25 ft., 
very rare ; 12 ft., rare ; 6 ft., rare.

A fragmentary specimen was found in the Gault of Folkestone 
which is clearly referable to the above species. V. sparsicostata 
belongs to the series of triangular Vaginulinse, with obscure seg- 
mentation and vertical or radial strigillate markings on the surface 
of the shell ; the initial portion of the shell is distinctly pointed. 
The above species is recorded by von Beuss from the Upper Hils- 
thon of N. Germany, and the same species is noted in the author’s 
MS. as associated with the Foraminifera from the Neocomian (Lower 
Greensand) beds of Guildford, in Surrey. 
The only specimen found at Folkestone was from zone v. of the 
Gault.
