216 Descriptions of New Species of Achatinella. 



Var. g. — Ash or olive brown, with one or more light bands. 

 Var. h. — Chestnut or olive brown, with fine, black, spiral 

 lines. 



Smaller, with outlines of spire less convex ; passing into A. 

 plumata. 



Average weight 5.30 grains. 



Habitat. — Vars. i-k in Kailua ; vara, l-o in Olomana. 



Var. i. — White, with numerous chestnut bands on the lower 

 part of the whorls. 



Var. j. — Light olive brown, with dark bands. 



Var. Jc. — Dark brown, with narrow white bands. 



Var. I. — "White, with one or two broad black bands at the 

 base. 



Var. m. — Elongate, white, with two black bands, one revolv- 

 ing above the suture, the other entering the aperture, and some- 

 times a third accompanies the sutural margin. 



Var. n. — White, with from three to five crowded bands at 

 the base. 



Var. o. — Pure white. 



Remarks. — May be grouped with A. Buddii and A.fulgens 

 Newc, but differs in its more solid structure, its thicker lip and 

 columellar fold, and in the more convex outline of its spire. It 

 also lacks the black tip which characterizes A. Buddii. The 

 typical varieties found in Keawaawa are rare, the sterile 

 region affording but few trees, which occupy the ravines near 

 the summit of the ridge. 



The varieties of Kailua (i, j, and k) pass into A. plumata 

 Nob. ; and var. m of Olomana bears a strong analogy to A. 

 zonata Nob. and A, formosa Nob., which are found at the 

 opposite end of the mountain range constituting the back-bone 

 of the island.
