Shell oblong-ovate, of an opake milk-white colour, distantly macu- 

 lated with dark reddish brown irregular markings, internally white ; 

 spire acuminated, constituting the greater half of the length of the 

 shell ; volutions seven to eight, convex, their posterior margin gene- 

 rally very obtusely and distantly coronated ; aperture wide, rather 

 straight ; outer lip thin at the edge, even, no denticulation within, 

 margiuated ; inner lip even, having a very slight straight edge or varix 

 externally, from which rather strong striations pass over the anterior 

 of the dorsum to the outer lip, and very much finer strise longitudi- 

 nally pervade the same ; channel short and Avide, very slightly curved. 



This shell diifers from Columbella Miser, Sowerby, in the absence 

 of denticulation, in the last volution being much more gibbous, the 

 aperture much wider, the channel decided, the spire more pyramidal, 

 and much less coloration and markings. 



Length, ^-^ of an inch ; width, -^-^ of an inch.

Shell oblong-ovate, shining, thick, strong, of a white colour, gene- 

 rally irregularly and greatly covered, more or less intensely, with an 

 almost black-brown coloration, excepting the posterior edges of the 

 whorls, where it remains nearly white ; spire acimiinated, constituting 

 one half the -length of the shell, has seven to eight volutions, rather 

 convex, slightly diagonal ; strong, prominent, somewhat distant varices 

 exist on the posterior margin of the last whorl, the anterior portion 

 of which have many strise passing transversely and obliquely for- 

 wards from the columellar edge of the aperture ; aperture oblong, 

 rather square and straight, internally of a bluish white colour ; outer 

 lip straight, marginated, having a rather large notch at the junction 

 with the body of the shell, and having anteriorly to this notch, within, 

 about five or six slight denticulations, the posterior being the larger ; 

 inner lip smooth, vsdthout denticulation, edge slightly elevated and 

 thin ; channel short, rather broad. 



Length, -^^ of an inch ; width, -^-^ of an inch.
