162 ACHATINELLA BULIMOIDES. 



in the average. The following color- forms occur in a lot from 

 Kahana, Gulick collection. 



1. White, initial whorls often yellowish, lip .chocolate (f. 1). 

 la. Same, but whorls of spire with, a dark band (fig. la). 

 16. Brownish-cream color, spire as in la (fig. 16). 



2. "White or whitish, with two chestnut bands separated by 

 a peripheral white band; spire with a wide chestnut band 

 above the suture (fig. Ic). 



2a. Similar, but base entirely chestnut, usually lighter than 

 the bands (fig. Id). 



Forms la and 16 are blends between 1 and 2. 



In a lot of 49 specimens from Hakipuu, Gulick coll., all are 

 dextral. Color-forms fig. 1 and no. 2a, chestnut streaked with 

 darker, with a broad white band below the suture (pi. 28, fig. 

 2, Hakipuu) predominate, though there are some of the pat- 

 tern of fig. Ic. 



In another lot of 7 dextral shells in the Gulick collection 

 from Kahana the lip is white, slightly yellowish at the edge. 

 In three of them there are pale traces of brown banding, 

 chiefly on the spire ; the others being pure white throughout 

 (pi. 28, fig. 7). 



A. Candida Pfr. is generally admitted to be merely the white 

 form of ovata. The original figure is reproduced on pi. 30, 

 fig. 4. The description follows. Achatinella Candida Pfr. 

 Shell dextral, imperforate, ovate-conic, solid, striatulate, a 

 little glossy, pure white; spire convexly conic, the apex 

 minute, black, rather acute; suture light, thread-margined. 

 Whorls 6i/2, rather flat, the last 'three-sevenths to four-ninths 

 the length, obsoletely angular, rounded at base. Aperture 

 oblique, truncate-auriform; columellar fold moderate, super- 

 ior, oblique, subcompressed ; peristome brown-violaceous, 

 strongly labiate within, the right margin expanded, columellar 

 margin dilated, flat, thick, adnate. Length 22, diam. 11 mm., 

 aperture 10% x 5 mm. Sandwich Is., Frick (Pfr.). 



It is likely that all the patterns of A, fricki Pfr., except pat- 

 tern a, were based upon ovata. Pfeiffer's figs, la, 76, repro- 

 duced in my pi. 30, figs. 7a, 76, certainly look to me like ovata. 

 I do not feel competent to pronounce upon fig. 7, which has
