 tome thickened within ; external margin unreflected, arcuate ; 

 columellar margin dilated, adnate, usually margined with

'Station: On the Kukui (Aleurites triloba}, Ohia (Eugenia 

 malacctzcensis) , 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. c, 

 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. /, 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 towards 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, and 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 Reeve as 

 A. vulpina Fer., and others have followed him ; but a com- 

 parison of his figures with Ferussac's leads me to doubt his 

 correctness, and after an acquaintance with the species in 

 their native valleys, I do not hesitate to separate them as 

 distinct. The shell here figured corresponds more nearly to 

 what I have described as variety c (Gulick). 



Achatinella trilineata Gulick. "Shell sinistral, imperf or- 

 ate, ovate-conic, solid, shining, finely striated, white above, 

 yellow or green at the base, with three black bands, one su- 

 tural, one entering the aperture, and the other between the 

 two, revolving just above the suture ; apex somewhat obtuse ; 

 spire conical, slightly convex; suture with narrow margin,
