A. a. leucozona is either a highland or a lowland form of ^. a. napus. 

 The shell of plate 11, figure 28, looks like an intermediate form be- 

 tween A. a. napus and A. a. leucozona but closest to the color pattern 

 of A. a. leucozona. The embryonic whorls are light buff; first post- 

 embryonic whorl light buff, streaked with mikado brown, penultimate 

 whorl a yellowish tint of avellaneous streaked with wood brown, and 

 lined and banded with pinkish buff, last whorl above the periphery 

 banded and lined with pinkish buff and a narrow and a wide band 

 of buckthorn brown, at the edge of the periphery a band of light buff, 

 and a subperipheral band of raw sienna, base raw sienna banded 

 with a wide band of a light tint of antique brown axially streaked with 

 antique brown, below which is a line of argus brown. 



The usual form of the shell (pl. 3, fig. 31) in the Gulick ANSP 

 lot has the embryonic whorls white ; first two postembryonic whorls
