The shells at my disposal are not adult, the largest having only 

 3 'whorls, but when adult have must likely about the same dimen- 

 sions^'as the species. The shell has a smooth protoconch, the radiate 

 riblets (15 per millimetre) are flexuous, and the interstices very dis- 

 tinctly microscopically reticulated. The colour is uniformly fuscous. 



Diameter, 1-7 mm. ; height. 0-9 mm., with 3| whorls. 



Type in my collection.
