.ff#5. Molokai, within the coil of the Ti tree leaf, as it starts frorn 

 the trunk. 



Shell ovate-conical ; whorls 5, rounded ; suture deep ; aperture 

 ovate ; columella slightly callous ; striae finely decussated ; colour 

 rufous, alternating with broad longitudinal zigzag lines of white 

 covering the entire shell, with or without a white band encircling 

 the last whorl. 



This forms the commencement of the type alluded to under the 

 description of A. dubia.

 cussatim striatis ; sutura simplici; apertura ovata ; labro ex- 

 panso, subreflexo ; columella alba, bulimoidea in speciebus juniori-

 Hab. Waianoe, Oahu. 



Shell dextral or sinistral, thin, conically elongate ; whorls 6, with 

 finely decussating striae ; suture simple ; aperture ovate ; lip ex- 

 panded, slightly reflected ; columella white, bulimoid except in adult 

 specimens (which exhibit a callus) ; umbilicus small and perforate ; 

 colour light corneous, with radiating zigzag lines, and blotches of a 

 light colour. 



Found on bushes. 



The above shell approaches in its characters very near to the genus 

 Bulimus. It is referred to this genus from its disposition to be either 

 sinistral or dextral ; from its animal being viviparous ; and from old 

 specimens exhibiting a flat twisted columellar tooth. It forms the 

 terminus of a series of four species herein described, viz. A. Helena t 

 A. physa and A. grisea, all heterostrophe species.
