Shell ovately conical, dextral ; whorls 6, flatly convex ; suture 

 slightly impressed ; aperture ovate ; Up acute, thickened within ; co- 

 lumella white, short, broad and abruptly twisted ; colour light chest- 

 nut, with darker longitudinal stripes ; green at the base, white sutural 

 band for the last 2^ whorls, brown band on the suture above. 



But a solitary specimen of this species has been obtained. Its cha- 

 racters are, however, sufficiently striking to warrant in giving it a place 

 as a distinct species.

 lari, fusca ; colore castaneo cum lineis delicatis obsoletis, trans- 

 versis, obscurioribus, vitta alba suturam ultimam transiente et

Shell dextral, ovately conical ; whorls 6, flatly convex ; aperture 

 ovate ; lip acute, thickened within ; columella brown, short and tu- 

 bercular ; colour chestnut, with fine obsolete darker transverse lines ; 

 a white band traverses the last sutural whorl and cuts the body whorl 

 centrally ; around the columella is a broad white band, losing itself 

 in the aperture. 



Closely resembles the A. solitaria, and but for the widely distant 

 localities, might be taken for varieties of the same species. The mark- 

 ings and columellae are however quite distinct.

 tura semiovali ; labro simplici ; columella brevi, cum dente obliquo

Hab. Hawaii. 



Shell dextral, conical ; whorls 6, slightly rounded ; suture simple, 

 well-impressed ; striae numerous, longitudinal and well-developed ; 

 aperture semiovate ; lip simple ; columella short, with an oblique 

 plaited tooth ; colour of shell externally of a uniform light reddish 

 yellow, internally white or pale rose. 



This species belongs to a group, at the head of which stands A. ru- 

 bens of Gould. Its specific character is sufficiently marked. It is 

 one of three species thus far obtained on the large island of Hawaii.
