Shell umbilicate, thin, discoidal, carinate ; color pale straw, with 

 two narrow reddish spiral bands, the superior midway between the 

 suture and the periphery, the inferior encircling the base at a third 

 of the distance from the keel to the umbilicus, the carina is some- 

 times edged above and below by similar bands, peristome white ; 

 whorls 4 -j, increasing regularly until the final whorl, which in its 

 latter half contracts a little, the earlier whorls slightly convex, the 

 latter flat ; sculpture close, irregular oblique striation above and 

 below crossed by a few faint impressed lines in the neighborhood of 

 the keel ; apex obtuse, the embryonic shell apparently constituting 

 the first revolution ; suture impressed above becoming linear as it 

 proceeds, margined above by the keel of the preceding whorl ; base 

 flattened at the periphery, slightly swollen within ; umbilicus nar- 

 row, deep, exhibiting the volutions; aperture almost horizontal, 

 abruptly and deeply descending, peristome thin, widely reflected 

 throughout its circumference, pinched at the junction of the carina, 

 margins closely approaching, connected by a transparent callus.
