Descriptions of New Species of Achatinella. 223 



Length of a large specimen 1.06 inch (27 mill.) ; breadth 

 0.51 inch (13 mill.). 



Average weight 6.70 grains. 



Station. — On the Kukui (Aleurites triloba), Ohia {Eugenia 

 Malaccwcensis), and other trees. J. T. G. ! 



Habitat — Palolo, Waialae, and Wailupe, Oahu. J. T. G. ! 



Var. b. — White above, green or yellow at the base. 



Var. o. — Green at the base, white above, with one or more 

 green bands. 



Var. d. — Green, brown, or yellow at the base, upper whorls 

 radiated with white and brown, and banded with green or 

 yellow. 



Var. e. — Radiated with white, and reddish brown. 



Var.f. — "White except the suture and columella. 



Var. g. — Green or yellow ; passing into A. Stewartii Green. 



Var. h. — Green with one narrow, white, spiral band, passing 

 just above the suture. 



Var. i. — Yellow with white sutures, and a dark brown band 

 revolving beneath. 



Var. j. — Chestnut brown at the base, becoming paler to- 

 wards the apex, with several obscure, spiral, brown lines. 



Remarks. — The metropolis of the species is Palolo valley, 

 where it is very abundant. In Waialae and Wailupe, which 

 lie to the east, it gradually becomes more rare, aud disappears 

 in Niu, which has furnished me but one specimen of var. f. 

 In Manoa, on the west, it soon disappears, being found only 

 on the mountain ridge that separates it from Palolo. Dextral 

 specimens are very rare : I have a few from Waialae. 



This shell has been described and figured by Eeeve as A. 

 vulpina Fer., and others have followed him ; but a comparison 

 of his figures with Ferussac's leads me to doubt his correct- 

 ness, and after an acquaintance with the species in their native 

 valleys, I do not hesitate to separate them as distinct.
