Shell of a narrow oblong-conic shape, thin, histrous, 

 smooth, of a dark-yellowish horn-colour, marked occasion-

 Body sub-cylindraceous in the middle, by no means ven- 

 tricose, with a convex and gradual anterior declination. 

 Spire filling three-sevenths of the dorsal length, of five 

 tapering turns, that are barely convex, of moderately 

 fast longitudinal increase, occasionally white beneath the 

 slanting suture : penult volution rather large, moderately 

 high : apex very blunt, and little elevated. Mouth oblong- 

 lanceolate, being very bluntly (often indeed subtruncately)

 filling rather more than half of the total length, and 

 between a third and a fourth only of the ventral area. 

 Outer lip curling a little inwards, ferruginous at the simple 

 edge, which recedes rather suddenly below, not promi-
