The tmibocs of this shell being placed at some 

 distance from the anterior termination, give it a j 

 character not strictly agreeing with the " Razor .shells," I 

 but loading towards the grouji rejirescnted by Solen j 

 cultelliis, which wc shall include in the present mono- j 

 graph. I 



This is represented by a very young shell of doubtful 

 character in the British Museum, but the specimens 

 from which the present tiguro is taken present unmis- 

 takable characters.
