NO. I ACHATINELLA APEXFULVA DIXON WELCH 165 



The usual color pattern (pi. 3, fig. 18) is lighter and not so sharply 

 banded as that of typical heata. The form resembles roseipicta var. i 

 in shape and color pattern but dififers in shade and range of the color 

 patterns. The race is intermediate between A. a. roseipicta and A. a. 

 beata. The embryonic whorls are cartridge buff ; first two postembry- 

 onic whorls white, penultimate whorl banded in the center of the whorl 

 with a band of vinaceous fawn, last whorl below the white sutural and 

 subsutural bands pale vinaceous fawn or a dilute shade of pale vina- 

 ceous fawn, banded with vinaceous fawn, in the umbilical region a 

 band of white ; lip a faint tint of pale vinaceous fawn, columella callus 

 white. Length 20.0 mm., greater diameter 13.1 mm., spire height 

 I I.I mm. The usual form is not determined by measurement because 

 of insufficient material. This shell is probably near the usual form. 



An obese shell and light color pattern (pi. 12, fig. 9) has white 

 postembryonic whorls banded on the last whorl above the periphery 

 with a band of light vinaceous fawn darkening to vinaceous fawn on 

 the last half whorl, last half whorl below the periphery faintly shaded 

 or lined with a dilute tint of vinaceous fawn. Length 19.8 mm., 

 greater diameter 13.5 mm., spire height lo.o mm. The shell may have 

 pure white embryonic whorls. 



In the higher localities of 307-3 and 308-1 a form (pi. 12, fig. 10) 

 occurs which resembles in color A. a. aloha (pi. 12, fig. 2) except 

 that the bands are a darker shade and a different hue. The shell of 

 figure 10 also shows an elongate form ; postembryonic whorls white, 

 lined just above the edge of the periphery with two bands of pinkish 

 buff, a very dilute shade on the first whorl and darkening to a 

 stronger shade on the next two whorls, the lower band being pinkish 

 cinnamon on the last whorl, last whorl below the periphery banded 

 or lined with pinkish cinnamon the ground color pale pinkish 

 cinnamon. 



A dark color pattern (pi. 12, fig. 11) has a grayish-pink color; 

 first half of the last postembryonic whorl below the white sutural 

 and subsutural bands ecru drab, tinted, faintly lined, and finely 

 axially streaked with light vinaceous fawn, last half whorl cinnamon 

 drab faintly tinted or finely streaked with benzo brown, at the edge 

 of the periphery a band of white, which fades out on the last half 

 whorl. 



In locality 308-2 and in other localities at the upper limit of area 106 

 a gray pattern (pi. 12, fig. 12) occurs which resembles aloha var. i 

 (pi. 12, fig. 3a), but does not have its obese appearance. The embry- 

 onic whorls are pale pinkish buff; postembryonic whorls white, banded
