50 Original Descriptions of AchatincUa. 



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. F. White except the suture and columella. 



Var. G. Green or yellow ; passing to A. stewarti 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 baud 

 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 onlj^ 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. vid- 

 pina Fer., and others have followed him ; but a comparison of his 

 figures with F^russac's leads me to doubt his corredlness, and after 

 an acquaintance with the species in their native valleys, I do not 

 hesitate to separate them as distinct. 



The shell here described corresponds more nearly to what I 

 have placed as Var. C. — Gk. 



Hab. Palolo, Waialae and Wailupe. — Gk. 



This species is very variable and is closely related to the shells 

 of the divers a group.
