i6o Original Descn'ptiotis of Achatinella. 



281. Achatinella micans Pfeiffer. 



A. {Lamhiclta) micans Pfr. P. Zool. Soc. London, 1859, p. 31. 



T. subperforata, dextrorsa, turrita, solidula, sub epidermide lutea> 

 glutinoso-micante alba; spira regulariterattenuata, apice acutiuscula; sutura 

 subcrenata; anfr. 7 convexiusculi, tdtimus 1-3 longitudinis vix superans, 

 rotundatus ; lamina columellaris parvula, obliqua ; apertura vix obliqua, 

 subovalis ; perist. simplex, rectum, margine columellari. Long. 16, diam. 

 7 2-3 mill. 



Shell subperf orate, dextral, turreted, somewhat solid, under 

 the yellowish epidermis, white with a glutinous sheen, spire regu- 

 larly attenuate, apex somewhat acute ; suture slightly crenulate; 

 w^horls 7 somewhat convex, last barely more than 1-3 of the length 

 rotundate; columellar fold small, oblique; aperture scarcely oblique^ 

 suboval; lip simple, erect, slightly dilated at the margin of the 

 columella, nearly free. 



Hab. Waianae Mts. 



282. Achatinella albolabris Newcomb. 



A. albolabris Newc. P. Zool. Soc. London, 1S53, p. 149, pi. ,xxiv. fig. 56. 



Shell conically ovate; apex acute; whorls 6, rounded, not 

 margined ; aperture ovate ; columella short, plicately toothed; lip 

 semilunar, thickened and white; color dark umber, wath a yellow 

 sutural line; wdthin bluish white. Long. 14/20, lat. 6 1/2/20 polL 



We are compelled to separate this and another, the A. reticu- 

 lata, from A. micleola of Gould, from which they differ in import- 

 ant and permanent charadlers. 



The shell figured by Mr. Reeve, though not a fine specimen, 

 clearly belongs to this species. A. nudeola Gould is quite distinct, 

 and is found on the island of Kauai, not Oahu, where this species 

 is met with. — Newc. 



Hab. Waianae. — Newc. Kapalama and Kalihi. — Bald.

 with fine incremental lines, apical whorls smooth ; color light 

 brown, apex darker; destitute of epidermis; whorls 51-2, some- 

 what convex; suture moderately impressed; aperture oval, a trifle
