The typical pattern occurs on 78 percent of the shells in the type 

 locality. One light gray shell (pi. 8, fig. 31) was found in the lot 

 which also shows a narrow specimen. Length 16.6 mm., greater di- 

 ameter 1 1.2 mm., spire height 8.5 mm. The first postembryonic whorl 

 and a half are white, last whorl and a half pale mouse gray darkening 

 to drab gray on the last half whorl, tinted above the periphery with 

 pinkish buff, banded with white and faintly lined with benzo brown. 

 Two specimens had a chocolate-lined pattern (pi. 8, fig. 31a) ; post- 

 embryonic whorls pale smoke gray spirally lined, banded, and finely 

 axially streaked with chocolate; impressed sutural band chestnut. 

 The typical pattern (pi. 9, fig. i) may be lined and may lack the 

 pronounced peripheral light gray band on the last whorl, last half of 

 first whorl and first half of penultimate whorl smoke gray spirally 

 lined and axially streaked with chocolate, last whorl and a half smoke 

 gray spirally lined with light grayish olive, last half whorl streaked 

 with fuscous, last whorl streaked with pale smoke gray.
