24 Original Descriptions of Achatinella. 



Shell sinistral, subperf orate, globosely conical, finely striated 

 with lines of growth, dun, darker striped f sometimes marked with 

 a few spiral white and brown lines); apex almost white, nucleus 

 reddish horn ; whorls 6, first 4 somewhat plain, the others convex;

Shell dextral, subperforate, short ovate-conic, shiny, striated

 the periphery and on the base ; suture finely margined ; whorls 6, 

 first 4 somewhat convex, the others convex : aperture white ; lip

Hab. Reported to be from Ewa. — Sm. 



This shell seems very nearly allied to A. tnrbiniformis Sm., 

 a shell found in Lihue. The brown color is generally more marked 

 on the last whorl, howev^er. The shell is named from its pure white 

 spire, which seems to stand out from the inflated body whorl. An 

 almost pure white example has been reported from Wahiawa.
