LAMELLIBRANCHIATA. 119 



it from G. Voltzii Leym. The best specimens are in the cabinet of 

 Mr J. F. Walker, M.A., of Sidney Sussex College, one of which 

 shews the hinge. The teeth are small and slender; cardinal 

 tooth slightly bifid, anterior lateral (of the left valve) laminar, 

 double, posterior lateral obsolete ; behind the umbo a well-marked 

 ligament support is seen. 



Localities. Upware, Folkestone, Shanklin, Punfield, under the 

 Punfield series (Meyer).

 Saleve.

I only know of one specimen, and in this the shell itself has 

 been lost, leaving only the inside cast. Therefore there is some 

 doubt in this identification. The cast is figured by Pictet and 

 Campiche, Pal. Suisse Terr. Grd., St Croix, pi. cxxi., f. 3, 4.

The discovery of the hinge teeth in the closely-allied species 

 C. squamosa, n. sp. (see infra) proves this to be a Cypricardia. 

 I have no doubt as to the above identification of this shell, having 

 compared specimens with Professor Geinitz in the Dresden Mu- 

 seum, but it is remarkable that this little shell should occur only 

 in two such widely separated localities, and in rocks of such 

 different ages.
