The outlines of the spire are a little convex, and the apex 

 is more obtuse than in A. rugulosa. The striation is rough 

 and irregular, and on the last 2y 2 whorls there are spiral 

 stricz, weakly shown in fig. 19. The spire is purplish-brown, 

 the last whorl of the same shade or lighter reddish-brown. 

 The pale sutural band and axial patch mentioned by New- 

 comb seem to be always present, though varying in intensity 

 and width. The first two whorls are smooth. The shape 

 varies from oblong-conic to ovate-conic.
