 figs. II, 12. 



From the fine series collected it appears that the ground-colouring, under 

 the zigzag periostracum, varies considerably. Shades of crimson or rich orange pre- 

 dominate, but occasionally the colour is confined to a band below the suture, the 

 rest of the shell being whitish. 



Hab. Lanai (Newcomb); mountains and behind Koele (Perkins).

The specimen here figured is not the one whose measurements were given in the 

 original diagnosis, but a slightly smaller shell whose periostracum is better preserved. 



Hab. Molokai (Perkins). 



subgenus A.mastrella, n. subgen. 



This name is proposed for a groiqj of rotund, generally incrassated, small forms, 

 which have been usually placed in Amastra. I take as the type A. rtignlosa Pease. 

 They are nearly all natives of Kauai, but a few species are found on other islands.
