Montagues specimen of this shell is still preserved in our Na- 

 tional Museum. As a species it is undeserving of attention, being 

 an immature sp)ecimen of (as we believe) a Columbella that has 

 been worn smooth, but which still retains some indistinct traces of 

 sculpture. It was one of the many exotic species stated to have 

 been taken by Laskey near Dunbar, and came probably from the 

 West Indies.

Shell minute, oval-conic, rather strong, yellowish white, en- 

 circled on the body-whorl by two not very wide rufous brown or 

 chocolate coloured zones, the lower one of which is basal and 

 stains the anterior tip of the aperture ; the upper, which is con- 

 tinued upon the smaller turns below their middle, only divided 

 from the suture by a pale strip of about its own breadth. Sur- 

 face adorned throughout with very numerous longitudinal nearly 

 perpendicular costellae or narrow ribs, whose intervals, which are 

 about equally broad, are crossed by moderately close-set spiral strice, 

 which, always strong, become especially so at the lower extremity. 

 Spire composed of about six shortish turns, whose suture is simple, 

 but which are clearly defined, tapering above, and simply convex ; 

 body more or less ventricose and convex, not attenuately produced
