86 Original Descriptions of Achatinella. 



This nia}' be classed with the following A. dccipiens and simi- 

 lar shells, which are found on the other side of the island of Oahu, 

 just over the high mountain ridge. I agree, however, with 

 Sykes, "that this may prove to be only a roughened form oiA. 

 by ronii Wood.'' This and the following rather elongate shells 

 might better be placed in Sedlion Achatinellastrum rather than 

 here, but I have not as yet made the change. 



^ 128. Achatinella decipiens Newcomb. 



A. decipir)is Newc. P. Zool. Soc. London, 1S53, p. 153, pi. xxiv, hg. 6S. 



Shell conically elongate, solid; whorls 6, slightly rounded, 

 margined above ; aperture elongately ovate ; lip subrefledled ; col- 

 umella short, obliqviely twisted, with an expanded callus; suture 

 slightly impressed ; strise numerous, longitudinal, oblique ; colour 

 white with yellow transvere bands, or yellow with white transverse 

 lines, and longitudinal chestnut-coloured stripes. Long. 16/20, 

 lat. 7/20 poll. 



This species cannot be confounded with any other than the 

 A. subvircns in one of its varieties, the distincftive marks of which 

 are given under that species. — Newc. 



Hab. Kahana. — Newc. 



This seems quite distinct from A. S2ihvirens, its habitat is on 

 the other side of the island, and with the three following shells 

 forms a natural group. They are so elongate that they might well 

 be considered as belonging to vSecftion Achatinellastrum. At this 

 point it is difficult to draw the line between the two secSlions.
