Hab. Bombay (Abercrombie). 
This wonderful little transversely sulcate and grooved species has 
some external resemblance to Irawadia trochlearis (W. T. Blanford), 
but can be at once distinguished by the plicate columella. There are 
four or five described species of this genus, mostly of Mr. Arthur 
Adams’ naming, from Japan. In the Pritish Museum is a specimen, 
also from Japanese seas, with the name as above, entirely comparable 
with our shell. He does not seem to have ever described it, as was,
