 Hab. Oahu (Baldwin). 



The difficulty of arriving at a satisfactory dividing line between A. viilpina and 

 A. producta is very great. As at present arranged, A. vulpina is the brown shell, 

 van steivarti the greenish coloured form, van crassidentata the parti-coloured, and 

 van liliacea the bandless variety; all the above being sinistral. A. producta on the 

 other hand is reserved for the larger and, usually, de.xtral form.

Testa dextrorsa, subperforata, nitida, turrita, solidula, levissime striata, alba, lineis 

 castaneis picta, apud peripheriam zona alba, in sutura linea nigro-castanea notata ; 

 anfr. 5 — 5^, regulariter crescentes, convexi ; apertura auriformis ; margine columellari 

 plica fusca mediocri munita, margine de.xtro acuto, callo parietali tenuissimo. Long. 

 I5'5, alt. 8'4 mill. .Plate XL fig. 19. 



A pretty little shell of the group of A. bella Reeve, of Molokai. A variety also 

 occurred (Plate XL fig. 20) in which the banding is almost obsolete, save in the suture 

 of the earliest whorls and in one strong dark band below the periphery. 



Hab. Maui, Wailua (Perkins).
