NO. I ACHATIXELLA APEXFULVA DIXON WELCH 95 



greater diameter 11.4 mm., spire height 9.6 mm., number of whorls 6; 

 postembryonic whorls white, penultimate whorl banded above the 

 periphery with light mouse gray, last whorl above the periphery light 

 buff faintly lined with white, and a line of sayal brown on the first 

 half of the whorl, 5 mm. behind the edge of the lip a streak or 

 tinting of tawny down to the supraperipheral band of light grayish 

 olive, last whorl banded at the periphery with white, below the periph- 

 ery ground white colored with a band of light grayish olive, which is 

 lined with two lines of fuscous ; impressed sutural band changes from 

 russet to avellaneous. 



The obese form of the shell (pi. 8, fig. 30a) and a yellowish or light 

 variant of the typical color pattern has the first postembryonic whorl 

 and a half white, last postembryonic whorl and a half warm buft' 

 axially streaked and spirally lined with white below the periphery the 

 ground is white or pale gull gray slightly tinted above the aperture, and 

 at the beginning of the last half of the whorl with spots of warm buft', 

 lined with warm sepia, on the last half of the whorl ; impressed sutural 

 l)and russet lightening to cinnamon buff on the last whorl. Length 

 16.2 mm., greater diameter 11.5 mm., spire height 8.1 mm. 



The usual form of a sinistral (pi. 8, fig. 306) and darker lined 

 variation of the lined pattern measures: Length 17.8 mm., greater 

 diameter 11.2 mm., spire height 10. i mm.; postembryonic whorls 

 cartridge buff, spirally lined and axially streaked on the first post- 

 embryonic whorl with cinnamon buff, penultimate and last whorls 

 lined with bone brown, at the periphery banded with white, below the 

 peripher}' the ground is white with a central band of bone brown 

 which divides into three on the last half of the whorl; impressed 

 sutural band tawny on the first whorl, on the remaining whorls cinna- 

 mon buff.

Plate 2, Figure 5 ; Plate 8, Figures 22-22C 



The color pattern resembles /^. a. lencorraphc, but differs in not 

 having a white sutural band, and in having the spire tinted with 

 yellow; first half embryonic whorl of the holotype (pi. 2, fig. 5) black, 

 next half of whorl upper half white, lower half black, last two em- 

 bryonic whorls upper half white, lower half chamois ; first post- 

 embryonic whorl light buff, spirally lined with white, first half of the 

 penultimate light buff' axially streaked with cinnamon drab ; the im- 

 pressed sutural band on the first postembryonic whorl and a half 

 tawny, on the last whorl and a half the sutural and subsutural
