 I placed it, with doubt, as a variety of varicosa, Eeeve. The 

 second example, received from Mr. Brazier, being mature, proves 

 that this form is distinct from Eeeve's shell. It displays, at 

 intervals, a slight tendency to varices, but not in such a marked 

 manner as varicosa, from which it is well distinguished by tlie 

 angular ribs, the more attenuated body-whorl, the dark brown 

 stripes between the ribs, and the series of brown dots on the in-

 the ribs of the whorl above. The aperture in the present species 

 is also narrower and longer, the columella straighter, and the 

 canal rather more elongate. The ribs on the body-wliorl near the 

 base and the interstitial ones between tliem, which sometimes
