D'Orbignv suggests that this may = S. hierredda, Rang; it 

 certainly resembles it. particularly the shell; but there is a still 

 greater external resemblance to S. tuberculata. although the 

 shells are different. The tubercles of the latter may be due to 

 irritation only, and the differences of cups and shell are possibly 

 only sexual.

Japan. 



Not unlike S. Jtcrtheloti in general appearance, but differs 

 from all other species in the great length of the second pair of
