I02 Orioinal Descriptions of Achafinella . 



i6o. Achatinella redfieldi Newcomb. 



.(. ii'dfii-ldi Newc. P. Zool. Soc. London, iS.s,,, p. 131 ; pi. \xii, fig. 5. 



Shell conically elongate, sinistral ; whorls 6, margined above, 

 striated longitudinally ; suture well impressed ; aperture subovate; 

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

 the columella ; colour of shell light fawm 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 Caniobi," 

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

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

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



Animal as long as the shell, greyish aljove, 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 d'cn'oJifii and 

 vi7\ouIata groups. 



161. Achatinella polita Newcomb. 



./. piilila Newc. Ann. I.\c. New York, vi, 185^;, p. 32.S. 



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 umljer ; sutures with or without a black Itand; 

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

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



This species shows two varieties with and without the sutural 

 band. The aperture of tlie 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 sedlion. 

 Perhaps it might be ])laced with the brlla group, but it is a much 

 smaller shell.
