334 EOCENE MOLLUSCA. 
Height, =sths of an inch. 
Locality. Sconce (Edwards). 
This shell has been figured by Sandberger, as above referred to, who says (p. 298), 
“ Pupina (?) levis, F. Edwards, in litt. et specim., 1861,” but the specimens in Mr. 
Edwards’ cabinet in the British Museum have the name Cistula levis attached. This 
I mention to prevent confusion hereafter. 
Genus 30th.—Pomatias. Hartmann, 1821. 
This generic name does not appear to be generally adopted, and there is some little 
confusion respecting it from the great similarity of the two generic names, Pomatia, 
Beck, 1837, a portion of Helix (H. pomatia?), and Pomatias, Hartmann, 1821 
(Cyclostoma patula). The British Eocene shell having, however, been figured by 
Sandberger under this generic name, I think it best to retain it so.

CycLostomMa LAMELLOSUM, F. E. Edwards, MS. 
Height, §ths of an inch. 
Locality. Weadon Hill (Edwards). 
This is, I believe, very rare as a British fossil, and I know it only in Mr. Edwards’ 
cabinet, by a specimen from which my figure is taken. That given by Sandberger was 
also taken from a specimen sent to him by Mr. Edwards.
