 them, and of examining and comparing the animals which form them . 



* The upper scar in dorsal valve large; two lower scars smaller, 

 and nearly under the upper one. Shell suborbicular. Anomia. 



"(• European. 



1. Anomia ephippium.

 ternally pearly. The upper scar large, oblong, the two others rather 

 smaller, subequal, one above the other ; the lowest of the two rather 

 more behind. Plug large, broad, short ; the sinus in lower valve large.
