48 Greenes new species of Achatina. 
not eroded — a deeply impressed line along the upper part 
of the whorls, parallel with the suture — periostracha smooth 
and very glossy — colour and markings exceedingly vari- 
ous — the ground colour is usually greenish or some shade 
of yellow — sometimes a single blackish coloured band ac- 
companies the suture — sometimes this band is double and 
of different shades — and on many specimens there are two 
bands, one at the suture and one in the middle of the whorls. 
In some varieties the base of the body whorl is dark brown, 
the rest of the shell being of a dark fawn, and not unfre- 
quently the whole shell is without any markings whatever; 
in which case the colour is yellow — the aperture, when in- 
verted, is ear shaped — the truncation of the collumella is 
rounded and thickened in a remarkable manner at its edge; 
along the inner margin of the outer lip there is a strong 
callous ridge, as in most of the species of this genus, which 
gradually attenuates towards the edge of the lip, which is 
thin and sharp inside — white and pinkish round the collu- 
mella. 
This splendid little Achatina was brought from Oahu, 
(Woahoo) one of the Sandwich Island, by the Rev. C. S. 
Stewart. He informs me that it is found in considerable 
numbers in the deep vallies of Oahu, at all seasons, adhering 
to the under surface of the large leaves of a plant called in 
the language of the natives Ti, and from the roots of which 
they brewed an intoxicating liquor, which was in general 
use before the arrival of the missionaries. Though the leaves 
of the Ti are the favourite resort of this Achatina, it is by 
no means confined to that plant. The Islanders sometimes 
eat the animal which inhabits this shell, as they frequently 
do fish, without cooking — but a favourite mode of preparing 
it, is to tie up in the large leaves of the Ti, considerable 
numbers of them at once — bake them thus with heated 
stones, and then pick out the animal with a small pointed
