(15) Amastra decorticata Gulick. 
Amastra decorticata Gulick, P. Zool. Soc. London, 1873, p. 84, pl. x. fig. 14. 
Dr Hartman has united this with A. ed/pso¢dea of Gould, from Maui, but a glance 
at Gould’s figures would have shewn him their distinctness. 
Has. Oahu, Kawailoa, Halemano, and various localities (Gulick); ridges of 
Nuuanu (Perkins). 
(16) Amastra durandt Ancey. 
Amastra durandi Ancey, Naturaliste, 1897, p. 178. 
Has. Oahu (Ancey). 
(17) Amastra ellipsoidea Gould. 
Achatinella ellipsoidea Gould, P. Boston Soc. 1. (1847), p. 200; U. S. Explor. 
Exped. Moll. pl. vir. fig. 96. 
A species unknown to me: Newcomb united it with his 4. pupordea, but it appears 
not to be so produced in form. 
Has. Maui (Gould). 
(18) Amastra elliptica Gulick. 
Amastra elliptica Gulick, P. Zool. Soc. London, 1873, p. 83, pl. x. fig. 15. 
Has. Oahu, Waialei, Kahuku, Hauula, Kawailoa (Gulick) ; Waianae (Hartman). 
Two specimens, collected by Mr Perkins on “ Waianae Mts. Oahu,” may belong to 
a large, incrassate variety. 
(19) Amastra extincta Pfeiffer. 
Achatinella (Laminella) extincta Pfeiffer, P. Zool. Soc. London, 1855 [1856], 
p. 204. 
? ? Leptachatina hartmani (Newe. MS.) Hartman, P. Ac. Philad. 1888, p. 54. 
I fancy that the new name given by Dr Hartman, on the ground that recent 
examples had been found, was due to an error of identification. Specimens submitted 
to me under the name of A. extizncta by Mr Baldwin appear to be only a form of 
A, similaris Pease. 
Has. Oahu, subfossil (Pfeiffer).
