(15) Amastra decorticata Gulick. 



Amastra decorticata Gulick, P. Zool. Soc. London, 1873, P- ^4' pl- ^- fig- '^^■ 

 Dr Hartman has united this with A. ellipsoidea of Gould, from Maui, but a glance 

 at Gould's figures would have shewn him their distinctness. 



Hab. Oahu, Kawailoa, Halemano, and various localities (Gulick) ; ridges of 

 Nuuanu (Perkins). 



(16) Amastra dia'andi Ancey. 



Amastra durandi Ancey, Naturaliste, 1897, p. 178. 

 Hab. Oahu (Ancey). 



(17) Afnastra ellipsoidea Gould. 



Achatinella ellipsoidea Gould, P. Boston Soc. 11. (1847), p. 200; U. S. Explor. 

 Exped. Moll. pi. VII. fig. 96. 



A species unknown to me : Newcomb united it with h\s A . ptipoidea, but it appears 

 not to be so produced in form. 

 Hab. Maui (Gould). 



(18) Amastra elliptica Gulick. 



Amastra elliptica Gulick, P. Zool. Soc. London, 1873, p. 83, pi. x. fig. 15. 

 Hab. 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.

p. 204. 

 ? ? Leptachatina hart )iia7ii {'^ ewe. MS.) Hartman, P. Ac. Philad. 188S, 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. extincta by Mr Baldwin appear to be only a form of 

 A. similaris Pease. 



Hab. Oahu, subfossil (Pfeiffer).
