The present species approaches some forms of S. crassinuclea, 

 but has a shorter spire and is less translucent. The Cuming 

 collection contains specimens bearing a label in Pfeiifer's hand- 

 writing. These have a slightly more slender spire than the figure 

 in the Conch.-Cab., but the shell illustrated by Hanley and 

 Theobald in Conch. Ind. is altogether different and pertains to 

 the new species described, supra.

This species is allied to S. Tiarileyi. A small form, measuring 

 6-5 mm. in length, from the type locality, is in the Cuming 

 collection. The shells, five in number, are accompanied by a label 

 in PfeifFer's handwriting.
