There was only one specimen of this in Mr. Bailey's collection 

 from Copack. During the Chevert Expedition to New Guinea 

 we purchased a large quantity of specimens from the natives of 

 Katow who obtained them at low water by digging for them in 



the sand.

This is the only specimen I have ever seen of this beautiful shell. 

 The valves are crossed transversely with distinct elevated lamellar 

 ridges, between which there are numerous striae running in a 

 longitudinal direction. It is tinged with pink, particularly in an 

 early stage of growth.
