i6o Original Descriptions of Achatinella. 



281. Achatinella micans Pfeiffer. 



A. {I.aminella) mu-aiis Pfr. P. Zool. Soc. London, 1S59, p. 31. 



T. subperforata, dextrorsa, turrita, solicUila, sub epidermide lutea, 

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

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

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

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

 7 2-3 mill. 



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

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

 larly attenuate, apex somewhat acute ; suture slightly crenulate; 

 whorls 7 somewhat convex, last barely more than 1-3 of the length 

 rotuudate; 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. alholnbi is Nevvc. 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, with a yellow 

 sutural line; within bluish w'hite. Long. 14/20, lat. 6 1/2/20 poll. 



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

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

 ant and permanent characfters. 



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

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

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

 is met wdth. — Newc. 



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



283. Achatinella pellucida Baldwin. 



Amastra pellucida Bald. P. Ac. Phil., 1895, p. 231, pi. xi, figs. 41, 42. 



Shell dextral, imperforate, very fragile, thin, translucent, 

 globosely conic, apex rather acute; surface lustreless, sculptured 

 with fine incremental lines, apical whorls smooth ; color light 

 brown, apex darker; destitute of epidermis; whorls 5 1-2, some- 

 what convex; suture moderateh' impressed; aperture oval, a trifle 

 oblique, livid-white within ; peristome simple, thin ; columella 

 white, flexuous, abruptly terminating in a thin lamellar plait. 

 Length 12 1-2, diam. 8 mm.
