ing very slightly in front. Outer margin of lip regularly 

 curved, pale brown within, strongly thickened, bordered with 

 yellowish white; columellar margin thin, reflexed, adnate 

 above; both margins united by a thin whitish callus. Um- 

 bilicus (when present) a long narrow slit along the columella. 

 Length 9.4, diarn. 5.3, length of aperture 4.9 mm. 



West Maui: Abau-ka-imu (Thaanum), Maunahoomaha 

 (Thaanum, Cooke). 



A very obese species, probably related to L. nitida Newc. 

 and L. compacta Pse. In outlines it recalls L, glutinosa Pfr. 

 from Oahu. This species seems to be restricted to the rather 

 higher altitudes of West Maui. There is a light corneous 

 variety of this species.

"Shell dextral, ovately fusiform, somewhat thin, under a 

 lens slightly striate, pale corneous, shining, pellucid, apex 

 somewhat obtuse, whitish corneous ; suture simple, lightly im- 

 pressed ; whorls 6-6%, flatly convex, the last more than equal 

 to % the length of the shell ; aperture pyriform ; lip with the 

 dextral margin slightly thickened, whitish corneous within, 

 columellar margin narrow, parietal margin lacking. Length 

 9.25, diam. max. 4.9 mm.

 (Thaanum). 



Lepiachatina smithi SYKES, Proc. Malac. Soc. London, ii, 

 1896, p. 128 ; Fauna Haw., ii, p. 369, pi. xi, fig. 29. 



This species is most easily separated from L. perkinsi by its 

 more acute and closely coiled embryonic whorls. The original 

 figure is copied.

"Shell imperf orate, dextral, acuminately ovate, thin, shin- 

 ing, pellucid, brownish corneous, lightly striate, apex slightly 

 obtuse, suture paler, moderately impressed; whorls 6-6%, 

 flatly convex, the first slightly striate, the last equal to % 

 the length of the shell, almost smooth, aperture ovately pyri-
