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, w^as 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 :

Mr Baldwin has left A. Q^i^atttea 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.
