NO. I ACHATINELLA APEXFULVA DIXON — WELCH 97 



The shell of plate 8, figure 22h, is white, last two postembryonic 

 whorls tinted with cinnamon buff and spirally banded with pale drab 

 gray deepening on the last half whorl to light drab and hair brown, 

 the bands axially broken with white. The spire may be almost en- 

 tirely white (pi. 8, fig. 22c), banded with drab below the periphery, 

 which bands are broken by axial streaks of white, the last whorl 

 above the periphery has a few faint lines of cinnamon buff. 



ACHATINELLA APEXFULVA LEMKEI var. i 

 Plate 8, Figures 23-23& 



Area 68?: North Waiawa Stream, general region of locality 

 233Ga?, approximate elevation 1,300 feet, Lemke, 1932, on lehua 

 (Metrosideros), pua {Osmanthns), alani (Pelea) (figs. 4, 4a, p. 53). 



The locality is a wide one and extends up to locality 234G on the 

 Waiawa-Panihakea Ridge. The lots represent a mixture of two 

 races, A. a. lemkci var. i and A, a. lineipicta. Color patterns similar 

 to those found in locality 234G {A. a. lineipicta) are found mixed 

 with color patterns not occurring in locality 234G. For discussion I 

 shall take lot 113, Lemke collection, and describe only the unusual 

 patterns which markedly differ from locality 234G, and occur on 

 48 percent of the shells. 



The usual form (pi. 8, fig. 23) and color pattern of the shell has 

 the embryonic whorls bicolored, first half embryonic whorl natal 

 brown, shading to white on the upper fourth of the whorl, next half 

 whorl upper half white, lower half pale drab gray, remaining em- 

 bryonic whorls white banded with honey yellow just above the 

 edge of the periphery; first postembryonic whorl light buff spirally 

 lined with tawny ; impressed sutural band tawny ; remaining post- 

 embryonic whorls light buff finely lined and axially streaked with 

 tawny, banded on the lower edge of the penultimate whorl with 

 bone brown, last whorl below the periphery light buff, closely axially 

 streaked, spirally lined and banded with bone brown ; impressed sutural 

 band on last two whorls light buff ; lip and columella callus vinaceous 

 fawn. Length 17.5 mm., greater diameter 12. i mm., spire height 

 8.9 mm., number of whorls 6. 



The color pattern may be darker (pi. 8, fig. 23a), the first half 

 of the penultimate whorl russet axially streaked with tawny, last 

 whorl and a half light buff almost entirely covered over by spiral 

 lines and axial streaks of fuscous or carob brown ; impressed sutural 

 band light buff lined with tawny. An obese shell (pi. 8, fig. 23^), 

 length 18.7 mm., greater diameter 13.5 mm., spire height 8.9 mm..
