white; the first postembryonic whorl and a half white or pale pinkish 

 buflF, axially streaked with pale pinkish buff, last whorl and a half 

 pale pinkish buff axially streaked with vinaceous buff, avellaneous and 

 wood brown, and spirally lined with pale pinkish buff' ; impressed 

 sutural band same as the remainder of the whorl ; lip and columella 

 callus pale vinaceous fawn, outer edge of lip pinkish buff. Length 



17.7 mm., greater diameter 12.3 mm., spire height 9.4 mm., number 

 of whorls 6^. 



The obese form (pi. 9, fig. 7) and light color pattern has the post- 

 embryonic whorls white, penultimate and last whorls shaded by axial 

 streaks of a dilute color of vinaceous buff. Length 18.5 mm., greater 

 diameter 13. i mm., spire height 9.4 mm., number of whorls 6. An 

 elongate specimen (pi. 9, fig. 8) has the postembryonic whorls white 

 shading to tilleul buff' on the last whorl, last two whorls axially 

 streaked with avellaneous. Length 17.7 mm., greater diameter 



1 1.8 mm., spire height 9.8 mm. 



In the Russ lot from the region of 250-251-3*, lined forms similar 

 to plate 9, figure 80, are found ; the postembryonic whorls are white, 

 penultimate faintly spirally lined or banded with cinnamon buff and 

 sayal brown which are broken by axial streaks of white, last whorl 

 spirally lined and banded with sayal brown and warm sepia, the lines 

 and bands broken by axial streaks of white. This form is probably 

 one from the upper edge of area 74 because it is similar to the form 

 of A. a. ezi'aoisis var. 6 (pi. 8, fig. 7) found in locality 251-1-2. 



This light color form may be sinistral (pi. 9, fig. 9) ; the postem- 

 bryonic whorls a yellowish hue of vinaceous buff', axially streaked 

 with white.
