 known forms.

Shell rather solid, a little shining, quite narrowly but deeply 

 umbilicate. Spire conoid, the apex rather obtuse. Whorls 7, 

 slightly convex, separated by a slightly impressed and irregularly 

 crenulate suture, nearly smooth (but under a lens appearing deli- 

 cately striated transversely and corrugate-malleate). Last whorl 

 two-thirds the total length of shell. Aperture oblique, the margins 

 joined by a very thin and inconspicuous callus. Angulate above, 

 strongly produced obliquely below, and pinched in at the sides a 

 little above the base. Columella somewhat thickened and a little 

 reflexed, nearly straight above, then becoming very oblique and 

 sinuous at the base. Outer lip somewhat expanded, very narrowly 

 reflexed, a little dilated above, slightly straightened in the middle, 

 sinuated at base. Basal margin rounded and acutely margined. 

 Color white, rose-tinted toward the apex, ornamented with two 

 grayish violet-brown bands on the penultimate, three on the last 

 whorl, not extending quite to the lip. Bands showing within the 

 throat; peristome white. Length 30, diam. 13^, length of aperture 

 16 mill. (Dautz). 



Color var. albus, entirely white (pi. 9, fig. 13).

Differs from the related species by its shorter form and diverse 

 coloration.
