Achatinella longispira Smith. "Shell sinistral, elongate- 

 subconic, imperforate, glossy, striated with incremental and 

 very delicate transverse lines, yellow, promiscuously orna- 

 mented with (4 to 6) narrow spiral zones of green and brown. 

 Suture distinctly margined with deep brown. Whorls G 1 /^, 

 convex, the first 3% whitish. Aperture two-fifths the length, 

 white; peristome with the margin acute, bordered within; 

 columellar fold strong, roseate. Length 21, diam. 10 mm." 

 (Smith}. 



"Var. a. Shell shorter, ovate-conic. Length 18, diam. 

 10 mm. 



"Var. b. Shell yellow, ornamented with green zones." 

 (Smith). 



"Oahu: Halawa is the metropolis of the species; a few 

 specimens are reported by Mr. Frick to have come from 

 Ahuimanu (Gulick). 



"This species is most nearly related to A. analoga Gk. which 

 is readily distinguished from this by the two black lines upon 

 the periphery of the whorl. The black or dark brown lines of 

 that species belong to the solid substance of the shell, while 

 the green and yellow bands of this species belong to the 

 epidermis. No dextral form of this shell has been found" 

 (Gulick).

 subconic, glossy, indistinctly and very minutely striated with 

 incremental and transverse lines; dilute buff-green, encircled
