The present species approaches some forms of /S'. crassinuclea, 

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

 collection contains specimens bearing a label in Pfeiffer'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.
