NO. I ACHATINELLA APEXFULVA DIXON WELCH II5 



lined with natal hrown; impressed sutural band vinaceous buff. 

 Length 16.1 mm., greater diameter 11.8 mm., spire height 8.9 mm. 



The lightest color pattern (pi. 9, fig. lyc) occurring on 31 percent 

 of the shells has the postembryonic whorls white spirally lined on the 

 last two whorls with light mouse gray and mouse gray, which lines 

 are broken by axial streaks of white ; impressed sutural band white, 

 upper edge fawn color. This specimen also shows a sinistral shell. 

 Four percent have a pattern similar to that of plate 9, figure i/d ; 

 postembryonic whorls white, last two whorls with a band of chocolate 

 just above the edge of the periphery, just below the edge of the 

 periphery a band of white, remainder of the base wood brown, lined 

 and banded with natal brown. Two specimens in the lot of 75 shells 

 have a color pattern resembling typical A. a. apexfulva. One of these 

 (pi. 9. fig. lye) has the first embryonic whorl army brown, next 

 whorl upper two-thirds white, lower third natal brown, last embryonic 

 whorl white ; last two postembryonic whorls chocolate faintly axially 

 streaked on the penultimate with orange cinnamon. 



Group of A. a. irwini Pilsbry and Cooke 



ACHATINELLA APEXFULVA EWAENSIS, new subspecies 



Plate 2, Figure 15 ; Plate 7, Figures 23-240 



The shell is similar to A. a. invini but differs in being smaller and 

 having a characteristic series of reddish-brown banded color forms 

 which dift'er entirely from A. a. inmni. The embryonic whorls of 

 the shells of A. a. etvacnsis and its varieties are usually banded with 

 a deep shade of yellow such as dresden brown, chamois, or cinnamon 

 buff". A. a. irwini and its varieties usually do not have the embryonic 

 whorls banded with yellow. A few specimens of A. a. irzviui do have 

 the embryonic whorls banded with tints of yellow, such as cartridge 

 buff and cream buff, but never intensely banded with yellow. 



The embryonic whorls of the holotype (pi. 2, fig. 15) are bicolored, 

 upper half white, lower half banded with dresden brown shading to 

 buckthorn brown on the last embryonic whorl and a half ; postembry- 

 onic whorls white faintly tinted with faint lines of pale gull 

 gray, last whorl lined at and below the periphery with seal brown ; 

 lip and columella callus tinted with light brownish vinaceous. Length 

 17.0 mm., greater diameter 12. i mm., spire height 8.5 mm., number 

 of whorls 5|-.
