Without Mr. Smith's assistance I should not have identified the specimens, as the quoted 

 UL r ures seem to bc not characteristic, those of Weinkauff and TRYON are more or less accurate 



of Reeve's figure. The ribs are not so strongly angular as figured by Reeve, 1 see no 

 whitish band. The species appears to be rather variable in number of ribs and in their being 

 more or less rounded. Tryon Iocates the species in Mangilia.
