this species as found on tlie East coast of America ; but 

 this identification Yerrill (1884, Proc. Conn. Acad. Ti. 261)

no. 115, ix. 31. JIah. The Gruinea coast. (N.) Dunker 

 got two separate valves from Loanda. Nobre, besides 

 adding Sierra Leone, gives it as dredged in Eunchal Bay. — 

 The species is one I have never seen. Dunker's authority 

 is of course of great weight ; his figure, but less so his 

 description, suggests the young form of P. fenestratus, 

 Eorbes.
