71 and area 72, or locality 241-1-242-3?, Riiss, 1931, BBM 134151 

 (figs. 4, 4a, p. 53). 



Area 72 is not very accurately plotted on a map. All of Welch's 

 material consists of dead shells. The Russ material covers a con- 

 siderable area so that areas 72 and 71 overlap. However, from 

 the material on hand the shells appear to be intermediate between 

 the forms found in area 71 and 70. The usual pattern (pi. 2, fig. 10) 

 has the embryonic whorls similar to A. a. lineipicta; the first post- 

 embryonic whorl white, penultimate whorl white deepening in color to 

 pale pinkish buff on the last whorl, last two whorls lined above the 

 periphery with hair brown and fuscous, last whorl at and below 

 the periphery pale gull gray spirally lined and banded with olive brown 

 and mouse gray; impressed sutural band russet becoming dilute in 

 color on the last half whorl. 



A few specimens have a gray color pattern (pi. 8, fig. 4), last two 

 postembryonic whorls pale gull gray finely axially streaked and 

 spirally lined with light gull gray. A single dark specimen (pi. 8, 

 fig. 5) from locality 242-2*, is white on the first postembryonic whorl, 

 lightly axially streaked with raw sienna, on the penultimate whorl the 

 subsutural band is warm buff axially streaked with sudan brown, 

 the remainder of the whorl seal brown lined with warm buff, last 

 whorl seal brown or black, subsutural band warm buff, lined with 

 russet; impressed sutural band russet; lip light vinaceous fawn.

Achalinella siviftii Newcomb, Pilsbry and Cooke, Man. Conch., vol. 22, p. 314, 

 pi. 58, figs. 4, 4a (only), 1914. 



The shell has a color pattern similar to A. a. polymorpha var. i 

 (pi. 8, fig. 29) only it lacks the characteristic white peripheral bands 

 on the last whorl, differs in shape and has a different series of color 

 patterns which usually have a ground of smoke gray. The first em- 

 bryonic whorl of the holotype (pi. 2, fig. 9) cream buff, remaining 

 embryonic whorls cartridge buff, banded on the lower half of the 

 whorl with chamois; first postembryonic whorl white, banded just 

 above the periphery with tawny; impressed sutural and subsutural 

 bands light vinaceous drab ; penultimate and last whorls light grayish 

 olive, tinted by fine axial streaks of smoke gray, last whorl banded 

 at the periphery and about the base with smoke gray; impressed 

 sutural band on the penultimate drab gray shading to avellaneous on 

 the last whorl ; lip and columella callus pale grayish vinaceous. Length
