MOLLUSC A 305 



van cinerea, n. van 



Banding almost black on the last whorl, ash coloured on the whorl above, the 

 upper whorls tinted with pale brown banding above the suture, replaced by an almost 

 black line at the apex. 



Hab. Oahu, Nuuanu (Perkins). 



Having examined the types of the first five species mentioned in the above 

 synonymy, I am unable to separate them specifically ; with a fair series of specimens 

 the forms shade one into another. The variety is noteworthy for its banding being 

 ashy and almost black, while in the typical form it is red-brown in various patterns. If 

 A. vestita be really this species it takes precedence in date : I have never seen a 

 specimen.

[Feb. 1856], p. 205. 



Hab. Oahu, Palolo and Konahuanui (Baldwin); Niu (Newcomb); Head of 

 Kawailoa Gulch (Perkins). 



The specimens found are of a puzzling form, shewing links between clementitia and 

 colorata. 



The animal, as described by Newcomb, seems to vary a good deal in colour. 



(19) Achatinella (^Bulimella) ampla Newcomb.

XXII. fig. 19. 

 Mr Baldwin considered this a synonym of A. colorata Rve. ; the only specimen I 

 have seen is the type, which is somewhat injured, and I incline to place it near 

 A. abbreviata Rve. 



Hab. Oahu, Koolau (Newcomb).
