 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. 



f European. 



1. Anomia ephippium. 



Shell white, yellow, rosy or red-brown ; upper valve radiated ; in- 

 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.
