a line of chamois on the lower portion of the whorl just above the 

 periphery. This can best be seen under a low-power microscope. 

 First postembryonic whorl white, banded on the upper half of the 

 whorl with tawny, remaining whorls white, last whorl below the 

 periphery benzo brown axially streaked with pale drab gray ; lip and 

 columella callus vinaceous bufif. Length 17.5 mm., greater diameter 

 12. 1 mm., spire height 9.2 mm., number of whorls 6. 



Distribution, area 65??: East Waiawa, "Ridge W. of Engineer's 

 camp, ^ mi. mauka [toward the mountains] of the ditch trail from 

 large koa tree down toward camp, on koa [Acacia koa'], pua 

 [Osmanthus'], guava [Psidium guajava]," O. H. Emerson, BBM 

 103967, 1915; also J. S. Emerson, BBM 102248, 1915. The exact 

 location is not known. The shells were surely found at a low eleva- 

 tion, because they were collected on trees that occur at a low eleva- 

 tion. Area 65 ? ? may possibly be the approximate region of the type 

 locality (fig. 4a, p. 53). 



A variation of the typical pattern (pi. 8, fig. 17) is similar to 

 A. a. chromatacme var. 2 (pi. 8, fig. i6a) ; first embryonic whorl 

 white, tinted with army brown, next whorl white, faintly banded on 

 the lower half of the whorl with cream bufif; postembryonic whorls 

 white, first half postembryonic whorl banded and streaked with 

 ochraceous tawny, last whorl below the periphery banded with 

 verona brown or snuflf brown. The usual narrow form (pi. 8, 

 fig. 17a) measures: Length 17.6 mm., greater diameter 11.4 mm., 

 spire height 9.5 mm. ; embryonic whorls white ; first half postem- 

 bryonic whorl tawny, finely lined with white, last half tawny, banded 

 on the lower two-thirds of the whorl with sorghum brown, penulti- 

 mate whorl white, banded on the first half of the whorl with sorghum 

 brown, last half with only a line of sorghum brown lightening to 

 sayal brown, last whorl above the periphery white, below the periph- 

 ery verona brown, finely lined and axially streaked with pale pinkish 

 cinnamon.
