Original Descriptions of Achatinella. 83 



Shell sinistral, imperforate, conic-oblong, somewhat solid, 

 quite smooth, glutinous-shining, tawny-golden yellow, more darkly 

 radiated ; spire somewhat convex-conic, subacute ; suture mar- 

 ginate ; whorls 6, hardly convex, the last a little shorter than the 

 spire, base saccate-rotundate ; aperture oblique, obauriform, white 

 within ; columella fold high, strong, twisted, rose ; lip thickened, 

 rose, outer margin slightly expanded, columellar margin dilated, 

 adnate. 



B. Slightly smaller, yellow-white, chestnut or greenish at 

 the base. 



Hab. Nuuauu and Kalihi. 



Dr. Cooke found the type of this shell to have the first and 

 second whorls white, third, fourth and fifth whorls yellowish, 

 suture of a slightly darker yellow than the ground color, lip and 

 columellar plait pink. The figure looks much like a shell now 

 known as A. lyonsiana Bald.

 mediana basique fuscis ornatus ; anfract. 6, convexiusculi ; sutura distincte 

 marginata; apertura alba; perist. crassum, fuscum ; plica coluniellaris 

 valida. Long. 16, diam. 10 mill. 



Shell ovate, sinistral, shining, white, last whorl yellowish,

There may be a mistake as to the habitat. I have never found 

 a shell anything like this from the Waianae mountains. The de- 

 scription and figure agree exactly with A. luteostoma Bald., banded 

 variety, a shell found high up on Mt. Olympus, the ridge back of 

 Manoa and Palolo valleys. Shell named because of its beautiful 

 brown band.
