 These two species have been united by Pease and Dr Hartman, the latter 

 remarking "The only example oi gigantea ever found is in the British Museum. It 

 probably equals a large example of ^. violacea, Newc." Probably the locality of Maui, 

 given by Newcomb, was an error, as his specimen appears to be only an elongate 

 form of the Molokai shell. This varies very much in size and shape, as may be seen 

 from the following : 



Alt. 34; diam. 16; alt. ap. 15 ; lat. ap. 9-5 mill. 

 ,, 31 ; ,, 12 ; ,, ,, I 1-5 ; ,, ,,7 

 ,, 3 ^ ' " 15'" " 13 ' " "9 " 

 Mr Baldwin has left A. criaantea in his list as a Maui shell, but the fact that this 

 diligent collector has marked it as a shell unknown to him, lends confirmation to the 

 view that it does not really come from that island.

 and Pelekunu (Perkins).—? Maui -Sl?, A. gigantea, Haleakala (Newcomb).
