I cannot separate the genus Woodia, of which this spedes is the 

 type, from Astarte by any distinct character. The hinge and teeth 

 are certainly the same ; and the pallial and muscular scars agree. 

 The present species varies in the comparative number of strise. Some 

 of my specimens are quite triangular. Single valves occurred in 

 great abundance off Cape Sagres and in Benzert Road.
