 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). 



(87) Amastra {^Laminella) veimsta Mighels. 



Achatinella vetmsta Mighels, P. Boston Soc. 11. (1845), p. 21 ; Newcomb, Ann. Lye.

 Binney, Ann. Lye. New York, xi. p. 191, pi. xiv. fig. D. 



Hab. Molokai, Mapulehu (Baldwin); mountains (Perkins). 



Mighels gave, but erroneously, ' Oahu ' as the locality.

 Plate XI. fig. 24. 



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 Amastkella, n. subgen. 



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

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

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