In this group there is an ill-defined ridge which strengthens the shell in 

 front of the narrow and elongate anterior adductor scar. In some of the 

 more curved and rounded species (Ensiculus) this ridge is more curved down- 

 ward, while in the typical species it is straight. In the absence of weightier 

 characters this feature can hardly be held of even sectional value. The group 

 is represented in the Parisian Eocene, and there is a single American species 

 of the section Ensiculus.

Eocene of the Claiborne sands at Claiborne, Alabama. 



Specimens of this small species have been obtained by Burns and John- 

 son, but mostly in a fragmentary condition. It is easily recognized by the 

 curved ridge in front of the adductor scar.

Blainville described his genus Solecurtus as consisting of three lettered 

 sections (not otherwise named by him), a single example being cited under 

 each. Section A had already been named Siliqua by Megerle von Muhlfeld ; 

 Section B was separated as Psammosolen by Risso the following year, leaving 

 to bear the original name of Blainville only Section C, typified by Solen legu- 

 men. The subsequently proposed names above enumerated must therefore 

 fall into synonymy. A slight difference in the hinge-teeth enables us to retain
