Original Descriptions of Achatinella. 93 



Shell ovate, oblong, subventricose, whitish, with chestnut 

 bands ; spire thickened, the lip pale brown. 



The ground colour, in some specimens, is pale chestnut or 

 ferruginous, banded with darker shades, and another of pure 

 white : in others the upper half of each whorl is whitish, and the 

 lower chestnut, marked by darker bands : the suture is scarcely, if 

 at all margined by a groove ; the aperture and pillar white. — Swain. 



Hab. Kawailoa. 



This has now become a very rare shell. On one occasion, 

 after a careful search, only one dead shell was found. The habitat 

 of this shell is not far from where the A. rosea is found. For that 

 reason it is grouped with that shell. It is, however, quite distinct.

 A. testa sinistrorsa, pallidc rosea, fasciis albis obsolctis. 

 Shell reversed, pale rose-colour, with obsolete white bands. 



I place this, for the present, as a variety of the last, to which, 

 except in being reversed, it bears a close resemblance in size, form 

 and general habit. It is entirely of a pale and delicate rose colour, 

 with two obsolete bands of white on the body whorl ; the margin 

 of the lip and columella are of a deeper rose colour, and the aper- 

 ture white. It should be observed, that the marginal groove, 

 which is scarcely perceptible in the last, is, in this, very distinct. 

 — Swain. 



Animal, when young, of a bright straw yellow, with ocular 

 apendages tinged with brown. In the adult, the color is a uni- 

 form light gray, with mantle and tentacles dark brown. — Newc. 



Hab. Wahiawa to Helemano. 



This is one of the most attractive of the Achatinellae. A large 

 number of color varieties can be found, from pure white to bright 

 rose ; yellowish brown and even greenish varieties have been found.
