 streaked with pale drab gray, last whorl drab axially streaked with pale 

 drab gray ; impressed sutural and subsutural bands white ; lip and 

 columella callus light vinaceous fawn. Length 19. i mm., greater di- 

 meter 13.7 mm., spire height lo.o mm. The gray pattern may be 

 lighter (pi. 6, fig. 21c) ; postembryonic whorls white, banded on the

Below locality 235, in localities 232, 233, 234, the brown pattern 

 is more prevalent, and usually of a lighter color than the usual brown 

 color pattern in locality 235. Gray color patterns are rare in these 

 lower localities, occurring on one or two specimens in each lot ; dex- 

 trals are also unusual. In the usual form and color pattern (pi. i, 

 fig. 53), the embryonic whorls shade from pale pinkish bufif to light 

 buff to pale pinkish buff; postembryonic whorls shade from light buff' 

 to warm buff, spirally lined with white, banded at the periphery with 

 a line of snuff brown, and a band of white, base banded with saccardo's 

 umber and pale pinkish buff; lip and columella callus light vinaceous 

 fawn. Length 19.3 mm., greater diameter 12.5 mm., spire height 



10.6 mm. The usual obese form (pi. 6, fig. 23) measures: Length 



19.7 mm., greater diameter 13.0 mm., spire height 11. i mm.; post- 

 embryonic whorls ochraceous tawny, base saccardo's umber tinted 

 with ochraceous tawny. An elongate specimen (pi. 6, fig. 23a) 

 measures: Length 19.4 mm., greater diameter 12.2 mm., spire height 

 II. 5 mm.; postembryonic whorls light ochraceous buff with a central 

 band of light brownish olive, last whorl banded above and below the 

 cartridge buff peripheral band with light brownish olive. A rare 

 purplish pattern (pi. 6, fig. 236) has the last two whorls dark vina- 

 ceous brown, axially streaked with white, peripheral band on last 

 whorl white; sutural and subsutural bands white. 



Another common pattern in area 42 is a streaked form (pi. 6, 

 fig. 22) ; the postembryonic whorls, below the subsutural and im- 

 pressed sutural bands of light buff, are snuff brown axially streaked 

 with light buff", peripheral band on last whorl pale pinkish cinnamon. 

 The lightest color pattern (pi. 6, fig. 22a), and an unusual specimen 

 in that the embryonic whorls are pale pinkish buff and not darker, 

 has the postembryonic whorls white, last whorl lined at the edge of 

 the periphery with a faint line of sayal brown, banded below the 

 periphery with hair brown bands which are streaked with white.
