Original Descriptio7is of Achatinetla. 101 



Hab. Kawela. — Pease. 



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

 Maui. It is nearly related to A. dwightii Newc. 



158. Achatinella tnucida Baldwin. 



A. tnucida Bald. P. Ac. Philad., 1S95, p. 222, pi. x, fig. 23. 



Shell sinistral, very minutely perforated, solid, acumiiiately 

 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 ash}- color, irregularly dis- 

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

 dark brown band at the periphery 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 generally 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, projecting tooth. Length 21 1/2, diam.11 1/2 mm. 



This species is found in the region intervening between the 

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

 characteristics 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.
