NO. I ACHATINELLA APEXFULVA DIXON — WELCH 45 



An obese shell (pi. 4, fig. 15a) shows the lightest color form of 

 this race; postembryonic whorls white spirally lined with pinkish 

 buff, below the periphery of the last whorl a faint line of verona 

 brown, below which are faint bands of pinkish buff, on the last 

 fourth whorl the bands are darker above and below the periphery, 

 being warm sepia and mikado brown. Length 17.3 mm., greater 

 diameter 12.7 mm., spire height 8.9 mm. The darkest color pattern 

 (pi, 4, fig. 15&) has the postembryonic whorls light ochraceous buff, 

 banded and axially streaked with hay's brown and sorghum brown, 

 base lined with white. The color patterns of figures 15a and 15^ are 

 rare patterns occurring only on a few specimens in area 8. 



ACHATINELLA APEXFULVA VITTATA var, 2 



Plate i, Figure 10; Plate 4, Figures 16, i6a 



Achatinella vittata Reeve, Pilsbry and Cooke, Man. Conch., vol. 22, p. 290, pi. 57, 

 figs. 4, 4a, 5-S& (only), 1914. 



Area 9 : Glen Ada, Nuuanu, locality 100-2*, approximate eleva- 

 tion 1,200-1,500 feet, R. A. Cooke, C. M. Cooke (figs. 3, 3a, p. 29). 



While series of shells from area 9 are quite distinct from typical 

 A. a. vittata or A. a. vittata var. i, because of the dominance of light 

 color patterns, nevertheless the color patterns of area 9 are repeated 

 in other areas and mixed lots are difficult to separate. 



The usual form of the shell (pi. i, fig. 10) has white postembryonic 

 whorls, banded on the last half of the penultimate with two bands of 

 fawn color, last whorl above the periphery banded with two bands 

 of cameo brown, lined below the suture with cinnamon buff, the 

 lines being broken with axial streaks of white, subperipheral band 

 cameo brown ; sutural band cinnamon buff ; lip and columella callus 

 vinaceous buff. Length 18.9 mm., greater diameter 12.3 mm., spire 

 height 9.9 mm., number of whorls 6. 



The lightest color pattern (pi. 4, fig. 16) has white postembryonic 

 whorls lined on the last whorl with walnut brown. An obese shell and 

 a rare dark color pattern (pi. 4, fig. i6a), found on only 6 percent of 

 the shells in the R. A, Cooke lot, has the postembryonic whorls white, 

 last whorl above the periphery banded with pinkish buff axially 

 streaked with cinnamon, banded at and below the periphery with 

 chocolate; impressed sutural band shades from tawny to ochraceous 

 tawny. Length 18.5 mm., greater diameter 12.8 mm., spire height 

 9.7 mm.
