Original Descriptions of Achatinclla. i6f 



Hab. Kawela. — Pease. 



In appearance, very similar to A. splcndida Newc, found on 

 Maui. It is nearly related to A. dwio/itii Newc. 



158. Achatinella mucida Baldwin. 



^1. »iiicida Bald. P. Ac. Philad., 1895, p. 222, pi. x, fig. 23. 



Shell sinistral, very minutely perforated, solid, acuminately 

 ovate, conic, apex rather acute ; surface shining, marked with 

 fine growth lines, and under a lens decussated by very delicate, 

 close, spiral striae. The shell of an ashy color, irregularl}' dis- 

 tributed over the surface, giving it a mucid appearance ; with a 

 dark brown band at the peripher}' which becomes sutural, extend- 

 ing both above and below the suture, and a small patch of the 

 same colour around the umbilicus ; also with a few inconspicuous 

 brown lines on the base and above the periphery, the latter con- 

 tinued above ; apical whorls generall}' denuded of cuticle, and 

 then of a light chestnut color. Whorls 7, slightly convex ; suture 

 moderately impressed. Aperture oblique, oval, livid white within; 

 peristome acute, slightly thickened within, expanded, basal and 

 columellar margins narrowly reflexed, light brown on both face 

 and the reverse ; columella tinged with brown, terminating in a 

 strong, plaited, projecfling tooth. I^ength 21 i/2,diam. 11 1/2 mm. 



This species is found in the region intervening between the 

 habitats of A. rcdjieldii Newc. and A. compta Pse.; and it has 

 cliara(5leristics connecting it with each of these species. It is 

 smaller than either, and differs from both in the coloration, par- 

 ticularly from the former in the absence of the white sutural band.
