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 may prove to be only a roughened form of A. 

 by •ronii Wood." This and the following rather elongate shells 

 might better be placed in Section Achatinellastrum rather than 

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



128. Achatinella decipiens Newcomb. 



A. decipiens Newc. P. Zool. Soc. London, 1853, p. 153, pi. xxiv, fig. 68. 



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

 margined above ; aperture elongately ovate ; lip subreflected ; 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 an}- other than the 

 A. S7ibvirc?is in one of its varieties, the distinctive marks of which 

 are given under that species. — Newc. 



Hab. Kahana. — Newc. 



This seems quite distinct from A. subvirens, 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 the)- might well 

 be considered as belonging to Section Achatinellastrum. At this 

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



129. Achatinella multicolor Pfeiffer. 



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



A. testa imperforata, dextrorsa vel sinistrorsa, conico-oblonga, solida, 

 striata et sublente minutissime decussata, nitida, lutea vel albida, fasciis 

 nigro-castaneis varie ornata, rarius unicolore ; spira elongato-conica, apice 

 subattenuata, acutiuscula ; sutura marginata ; anfr. 6, planiusculis, ultimo 

 2-5 longitudinis subaequante, basi rotundato ; apertura obliqua, truncato-

 nato. Long. 17, diam. 9 mill. 



Shell imperforate, dextral or sinistral, conic-oblong, solid, 

 striate, and under the lens very minutely decussate, shining, yel- 

 low or white variously ornamented with black-chestnut bands,

 what acute ; suture margined ; whorls 6, quite flat, the last nearly
