Descriptions of IFew Species of Achatinella. 177 



Var. J.— "With a rather broad, faint, brown band encircling 

 the body whorl, and revolving above the suture. 

 Var. <?.< — "With faint reddish sutural band. 



Station. — On the ground in the woods. J. T. G. ! 



Habitat. — Most of our specimens are from Lihue, Oahu, but 

 Kalaikoa, ~Wahiawa,IIelemanu, and Peula, have each furnished 

 one or two specimens. J. T. G. ! 



Remarks.- — It has been known in some collections as the 

 young of A. labiata Newc, but a comparison with the true 

 young of that species can leave no doubt in regard to its dis~ 

 tinct character. The specimen figured has the lip considerably 

 thickened, and is evidently full grown ; but if, as has been 

 maintained, a more perfect maturity should render the lip as 

 callous as in A. labiata ) it will be seen that the form is quite 

 distinct ; the spire being shorter, and the body whorl inflated. 



In size, form, and character of lip, it is more nearly allied to 

 A. dimidiata Pfr., which is readily known by its peculiar 

 arrangement of colors.
