Linnaeus described the West Indian shell as a distinct species, under the 

 name of Pholas pusilla, but Lamarck united the two, as P. clavata ; P. Tere- 

 diniformis and P. falcata are about half-grown shells, and P. semicostata is a 

 very young individual. The Philippine Island specimens do not diifer in any 

 respect from the West Indian. This species differs from M. cuneiformis 

 in the shape of the dorsal plate and in the anterior concentric striae being 

 angular instead of regularly curved.
