from just below the umbonal area. Where the original shell 

 is preserved, it is seen to be ornamented with very fine con- 

 centric striations originating from the summits, having the 

 tendency of rendering the radial costte somewhat indistinct. 

 The specimen likewise possesses a well-sculptured triangular 

 chondrophore (fig. 5), so characteristic of the genus, the outer 

 posterior sides of which form a pseudo-alation extending from 

 the divergent summits. 



Both valves of the specimen are in the closed condition. 



Vulsella is a characteristic genus of Eocene rocks, the 

 present species mainly differing from other described forms 

 in its rounder and more depressed valves.

This form of Spondi/his, although related to S. svhspinosus, 

 a species found in the Eocene rocks of Biarritz, Turkey, and 

 Asia Minor, is slightly more convex, and has a greater 

 number of costce, and consequently narrower longitudinal 

 grooves. The sculpture-striations (fig. 7) are, however, very 

 similar, being close together and nearly horizontal. The 

 only example found was the larger or lower valve.

Cardium sp. 



This specimen consists of a rough cast showing no sculp- 

 ture characters, but possessing closed valves with a greater 

 height ( = umbono-ventral measurement) tlianlength ( = antero- 

 posterior measurement), and showing subcentral and rather 

 convex umbones, the hinge-area being somewhat shortened. 

 It is almost impossible from its condition of preservation 

 to suggest any species with which this specimen might be 

 related, although its oblong and subglobose form resembles 

 Cardium gratum of Deshayes, a European Eocene species,
