Remarkably and very distinctly characterized by the two rows of 

 small tubercles which encircle the whorls. The sliell is otherwise 

 of an uniform white glassy colour, which might be attributable to its 

 condition.

The description is drawn up from a somewhat young specimen, 

 and the mouth and last whorl have not yet attained their full deve- 

 lopment. The character of the shell is however very conspicuous. 

 In this genus the last whorl will be found veiy frequently to offer 

 decided features, and becomes a valuable aid in the diagnosis.
