costated ; the spiral liise produce small nodose crenulations on the 

 costaj. The external ornament is much interrupted by inflated

 oblong, outer border lirate within ; columella with two small 

 transverse plications ; umbilicus partly covered over by the 

 columellar border. 



Dimensions. — Length 5 mm. ; breadth 2-75 mm. ; length of 

 aperture 2'5 mm.

This species is closely allied to C. capillata, but the longitudinal 

 costae are relatively larger and oblique ; columella with two 

 plications situated posteriorly. The specimen in the Museum 

 is not sufficiently well preserved to enable the protoconch, or 

 minute ornament, to be described. The general character of the 

 embryonic shell was, evidently, similar to the last- mentioned 

 species, however.
