86 Original Descriptions of Achatinella. 



This may be classed with the following A. decipiens 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 ma}' prove to be only a roughened form of y^. 

 byronii^ooA.'' This and the following rather elongate shells 

 might better be placed in Se(fl;ion Achatinellastrum rather than 

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



128. Achatinella decipiens Newcomb. 



A. decipiens Newc. P. Zool. Soc. I^ondon, 1853, p. 153, pi. xxiv, fig. 68. 



Shell conicalh' elongate, solid; whorls 6, slightl}' rounded, 

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

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

 slightly impressed ; striae 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. snbvire7is 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. svbvirens, 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 Se(5lion Achatinellastrum. At this 

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



129. Achatinella multicolor Pfeiffer. 



A. multicolor Pfr. P. Zool. Soc. London, 1S55, p. 4, pi. xxx, hg. 11.
