 the upper half of the last whorl striped with gray-brown, the lower 

 half yellow, banded wnth gray-brown. 



Affinities. It is allied to A . apicatiis Newc . , and A . lilacetis Gk . 

 Remarks. In Ahonui two-thirds of the specimens are sinis- 

 tral : in Kalaikoa only about one-eighth are sinistral. — Sm. 



Hab. Most abundant in Kalaikoa and Ahonui, but it is some- 

 times found in valleys to the west as far as Waialee. — Sm.

 .sublaevigata, cinereo-fusca. pallide subfasciata et nigro strigatula ; spira ele- 

 vata, conica, apicc fusca, acuta; siitura marginata, alba; anfr. 6, prirnis 3

 flato ; apertura obliqua, truncato-auriformi ; plica columellari supera, nodi- 

 formi, paruni torta ; perist. fusco limbato, margine dextro subrecto, stricti- 

 usculo. columcllari dilatato, appresso. Long. 21 1-2, diani. 13 mill. 



B. Nigra, pallide interruptc lineolata vel fasciata. 



Shell dextral (more rarely sinistral), imperforate, ovately 

 conical, solid, smooth, a.shy brown with fine pale bands and black 

 stripes; spire elevated, conical, apex brown, acute; suture mar- 

 gined, white ; whorls 6, fir.st three flat, the following somewhat 

 convex, the last inflated, equal to 2-5 of the length ; aperture ob- 

 lique, truncate-auriform ; columellar fold high, nodiform, slightly 

 twisted ; lip margined with brown, nearly erect at the right mar- 

 gin, somewhat constricted, expanded at the columella, appressed. 



Hab. H.I. — Frick. Helemano to Waialee. 



Mr. Baldwin places this with A. swiftii Newx. 



Ur. Cooke found the type shells to be longer and narrower 

 than the typical swiftii, and it may come from the Waianae side of 

 Waialua.
