I02 Original Descriptions of Achaiivella . 



i6o. Achatinella redfieldi Newcomb. 



.(. ictifu'hU Newc. P. Zool. Soc. London, 1H53, p. 131 ; pi. \xii. fig. 5. 



Shell conically elongate, .sinistral ; \vhorls 6, niargiiied al)Ove, 

 striated longitudinally ; suture well impressed ; aperture subovate; 

 columella brown, flat and twisted ; lip subreflecfled, of the colour of 

 the columella : colour of shell light fawn passing into deep chest- 

 nut, paler above, plain or variously marked with brown bands, and 

 obscure undulations on the third whorl only : a white band traverses 

 the sutures. Long. 20/20, lat. 9/20 poll. 



This species belongs to the native group of "Pupu Caniohi," 

 [Kaneohe] or singing snails, and it is with pleasure that we dedi- 

 cate it to J. H. Redfield, Esq., of New^ York. It is not an abundant 

 species. Found on Tutui, Ohia and Ti trees. — Newc. 



Animal as long as the shell, greyish above, sprinkled slightly 

 with brown, tentacles of same color, mantle slate, bottom of foot 

 of a greenish grey. — Newc. 



Hab. Mapulehu. — Bald. 



This shell seems to be intermediate between the dwioJilii and 

 virgulata groups. 



161. Achatinella polita Newcomb. 



.). poltia Newc. Ann. I.vc. New York. vi. 1S53. p. 32S. 



Shell dextral, polished ; whorls 5, convex, margined above; 

 suture well defined ; aperture oblong-ovate ; columella strongly 

 tuberculate, with purple tip; lip simple; colour yellow, upper 

 whorls tinged with umber ; sutures with or without a black band; 

 aperture within white or dark purple. Long. 12/20, lat. 6 1/2/20 

 poll. — P. Zool. Soc. London 1S53, p. 143. 



This species shows two varieties with and without the sutural 

 band. The aperture of the first is purple within, of the second a 

 pure white. — Newc. 



Animal of a uniform yellowish white including tentacles ; ten- 

 tacular sheath slightly tinged with brown ; mantle black. — Newc. 



Hab. Kaluaaha to Halawa. — Bald. 



This does not go well with any of the groups of this section. 

 Perhaps it might be placed with the bcUa group, but it is a much 

 smaller shell.
