The first postembryonic whorl of the holotype (pi. i, fig. i8) is pale 

 pinkish cinnamon spirally lined, banded, and tinted with sayal brown, 

 last two whorls sayal brown, last whorl below the periphery banded 

 and lined with white ; impressed sutural band white ; lip and columella

 O. H. Emerson, BBM 103962 ; also collected by J. S. Emerson, BBM 

 102203-102204, Dos Santos, BBM 74301, and Thwing, BBM 28544- 

 28546 (figs. 3, 3a^ p. 29). The locality has not been found in recent 

 years. Only an approximation has been made by Dr. C. M. Cooke, 

 and Dr. Oliver Emerson which is somewhere in the vicinity of the lo- 

 cality. The shell is named after Dr. Oliver Emerson, who dis- 

 covered it. 



A dark white-lined color pattern (pi. 4, fig. 31) has the last two 

 whorls banded with russet and lined with white. The darkest color 

 pattern (pi. 4, fig. 30) has the last two whorls liver brown axially 

 streaked with hazel, about the periphery of the last whorl a line of 

 white ; impressed sutural band white. The lightest color pattern 

 (pi. 4, fig. 30a) is white, Imed on the last two whorls with hazel. 

 This pattern occurs on only one shell in the type lot.

The shell is larger than A. a. simulans, having a characteristic 

 smooth surface, and usually having spiral bands which are generally 

 not broken by axial streaks. The form is closest to that of A. a. 

 cinerea, having an inflated last whorl. The holotype (pi. i, fig. 15) 

 has the first half of the first embryonic whorl rood's brown, last half 

 upper portion white, the lower half rood's brown changing to mouse 

 gray on the next whorl, on the last half of the second embryonic 

 whorl and on the remaining embryonic whorls the lower band is a 

 faint shade of cream buflf, upper band white; the postembryonic 

 whorls white, the first half of the first postembryonic whorl banded 

 on the lower fourth of the whorl with cinnamon buff, penultimate and 

 last whorls lined with cinnamon, last half of penultimate and last 

 whorl banded at the edge of the periphery with burnt umber, last 

 whorl below the periphery with a line of burnt umber; lip and
