Botalia umbilicata var. nitida, Id., 1897, Foraminifery Yrstev Belo- 
horskych (Palseontographica Bohemise, No. IY.), pp. 54, 55 and 72, 
pi. vii. fig. 25 and woodcut p. 53. 
The specific type of the above variety was figured by d’Orbigny 
from the Yienna Tertiary beds.* The species often recorded from 
Cretaceous strata as B. umbilicata f was held by Dr. Carpenter to be 
identical with B. Soldanii, % and in this view he was supported by 
Dr. H. B. Brady. § 
The variety nitida is similar to the type form in general outline, 
but is smaller and more delicate in the structure of the test. 
B. Soldanii var. nitida has been found in the Gault of France 
(Wissant) and the Department of l’Aube (Berthelin) ; and from the 
lower Planer-kalk and the Planer-mergel — Cenomanian and Turonian 
— of Bohemia (Beuss, Perner). 
In the Gault of Folkestone this variety was found in zone i., 
spec, b, rare ; zone ii., spec, a, rare ; zone ii., spec, b, rare ; zone ii., 
spec, c, very rare ; zone iii., rare ; zone iv., rare ; zone v., frequent ; 
zone vi., frequent ; zone vii., frequent ; zone viii., frequent ; zone ix., 
rare; zone x., rare; zone xi., 55 ft. from the top, common; 50 ft., 
common ; 45 ft., common ; 40 ft., common ; 35 ft., common ; 30 ft., 
common ; 25 ft., common ; 20 ft., common ; 12 ft., very common 
6 ft., common.
