Foraminifera of the Gault of Folkestone. By F. Chapman. 427 
This beautiful and variable form is rare in the Gault. It is 
strongly suggestive of an arrested or uni-laterally developed variety 
of Frondicularia Karreri or F. strigillata. 
V. discors is recorded from beds of Neocomian age (Speeton Clay) 
in N. Germany. It occurs in the Gault at Folkestone in zone vii., 
very rare ; zone xi., 6 ft. from the top, very rare.

This elegant little species is apparently peculiar to the Gault 
formation ; and, moreover, it is very rarely met with there, two speci- 
mens only occurring in an extremely large assemblage of Vaginulinse 
obtained from the Folkestone Gault-clay. It is also rare in the Gault 
of France. 
V. Bioehei was found at Folkestone in zone i., specimen b , very 
rare ; zone xi., 6 ft. from the top, very rare. 
Vaginulina Priceana , plate VIII. fig. 15 a, b. 
Shell sub-oval, produced at the oral extremity, and well rounded 
at the commencement. The sides are flat, and the margin rounded. 
Chambers numerous, eleven in the specimen found ; the first chamber 
oval, as in V. Bioehei (to which species this form bears some general 
resemblance), the rest narrow and recurved. The sutures of the 
chambers in the later growth of the shell are marked by a thickening 
or ridging of the shell, and this filleting extends beyond the general 
outline at the aboral end, appearing as blunt J prickles. The first 
half of the shell is obliquely and sinuously striated, but the sutures 
of the 8th, 9th, and 10th chambers are regularly decorated with short 
oblique strigillse; the margin of the last chamber is relieved by a 
sharp and interrupted ridge running more or less paralled with the 
edge of the shell. The aperture is situated just under the extremity 
of the last chamber, and consists of a simple! but slightly elongated 
orifice. Length of shell, 1/35 in. ; greatest breadth, 1/66 in. 
I have much pleasure in naming this species after Mr. F. G. Hilton 
Price, F.G.S., to whom students of Cretaceous geology are indebted for 
his valuable work towards defining the various zones of the Cretaceous 
strata, and especially of the Gault. 
V. Priceana was found at Folkestone in zone xi., 45 ft. from the 
top, very rare.
