NO. I ACHATINELLA APEXFULVA DIXON — WELCH I49 



ACHATINELLA APEXFULVA SUTURAFUSCA var. i 



Plate 3, Figure i ; Plate 10, Figure 23 



Achatinella apexfulva aplcata (Newcomb) Pfeiffer, Pilsbry and Cooke, Man. 

 Conch., vol. 22, p. 326, pi. 60, fig. ya (only), 1914. 



Area 85 : South Poamoho Stream, locality 280-7, elevation 

 1,300-1,350 feet, Welch and C. W. Isle, 8 sinistral 1935 (figs. 5, 50, 

 p. 105). 



The form is close to typical A. a. suturafusca, but differs in having 

 a mars brown impressed sutural band, and the postembryonic whorls 

 not colored with as bluish-gray streaks as A. a. suturafusca. More- 

 over, the dark color pattern (pi. 10, fig. 23) is not known to me from 

 area 86. 



The light color form (pi. 3, fig, i) has the embryonic whorls tawny ; 

 first fourth postembryonic whorl tawny, the remaining whorls tilleul 

 buff or pale drab gray axially streaked with deep mouse gray and 

 mouse gray, the last two whorls faintly spirally lined with deep mouse 

 gray; lip and columella callus light grayish vinaceous. Length 19.8 

 mm., greater diameter 13.1 mm., spire height 10.6 mm. So few 

 specimens are known from this area that the usual form and color 

 pattern is not determined. 



The dark color pattern (pi. 10, fig. 23) has the embryonic whorls 

 amber brown ; postembryonic whorls clove brown or black axially 

 streaked with drab gray, last eighth whorl verona brown ; impressed 

 sutural band bone brown or black. Length 18. i mm., greater diameter 

 12.7 mm., spire height 9.0 mm. 



ACHATINELLA APEXFULVA SUTURAFUSCA var. 2 



Plate 3, Figure 13; Plate 10, Figures 25-250? 



Achatinella apexfulva apicata (Newcomb) Pfeiffer, Pilsbry and Cooke, Man. 

 Conch., vol. 22, p. 326, pi. 60, figs. 4, 7(?) (only), 1914. 



Area 89: North Poamoho Stream, locality 290*, elevation 

 1,300 feet, Meinecke, 1914, 191 7, 4 dextral, 8 sinistral 1926; Wahi- 

 awa, Gulick, ANSP 92628 (figs. 5, 5a, p. 105). 



This race is very similar to A. a. suturafusca (area 86) but differs 

 in usually having a more purplish-gray or darker color pattern. 

 Brownish color forms similar to A. a. apicata also occur in area 89 but 

 not in area 86. The form also resembles A. a. suturalha but differs in 

 having a brown sutural band. This variety is an intermediate one 

 between A. a. apicata and A. a. suturalha.
