This neat little shell is short-fusiform in shape. It has six 

 whorls of which the apical ones are smooth and mammillary, while 

 the succeeding ones are shouldered and furnished with varices 

 numbering ten on the body-whorl, every two of which approach 

 at the shoulders and form a tubular spine. Of these two varices, 

 the anterior one is more bent than the posterior. Canal long and 

 bent. 



Several specimens, all witli tubular spines broken. The}^ are 

 smaller than those figured by SoAverby, the largest (only 77 millim. 

 in height) being not cjuite one-half as large. 

 Fossil occurrence. — Shito.
