Newcomb considered this a form of A. decipiens; Dr Hartman appears to have 
been in some confusion, as he placed it (P. Ac. Philad. 1888) at p. 29 under A. deczpzens, 
and at p. 30 under 4. vzvzdans. I have seen a long and characteristic series found on 
the Island of Oahu by Mr Hutchison.

Newcomb considered A. de//a to be a more banded variety of A. curta Newc. ; 
from the material I have seen I incline, with doubt, to leave them distinct. 
Has. Oahu, Kalaikoa, Halemano, &c. (Gulick).

Achatinella diluta Smith, P. Zool. Soc. London, 1873, p. 75, pl. 1x. fig. 14. 
It is near to, but seems distinct from, A. /zgata Smith, with which Dr Hartman 
placed it. 
Has. Oahu, probably (Smith).
