ture pyriform, dextral margin acute, columellar margin sub-

Leptachatina vana SYKES, Fauna Hawaiiensis, ii, Moll., 

 1900, p. 372, pi. xi, fig. 27. 



"A brownish horny, pyramidal shell which has no strik- 

 ing characters." (Sykes.) Mr. Sykes' figure is copied. 



35. L. CAPTIOSA n. sp. PL 11, fig. 12. 



The shell is minutely perforate, ovate, corneous, nearly 

 solid, hardly diaphanous, scarcely glossy, under a lens faintly 

 and closely striated with lines of growth. Spire nearly 

 conic, with slightly convex outlines; apex rounded. Suture 

 simple, scarcely impressed. Whorls G 1 ^, the first 3 closely 

 coiled, nearly flat, the rest increasing more rapidly, very 

 slightly convex, the last large, nearly cylindrical, tapering 

 very gradually towards the base. Aperture rather large, sub- 

 ovate, very slightly oblique, nearly perpendicular. Columella 

 nearly straight, arcuate below, with an acute callus along 

 its face ; columellar fold rather strong, nearly basal, oblique, 

 extending to the outer margin. Outer lip slightly arcuate, 

 distinctly thickened; columellar margin thin, adnate above; 

 both margins united by a thin, transparent callus with its 

 outer edge slightly thickened. Umbilicus very minute. 

 Length 10.0, diam. 5.0. Length of ap. 4.8 mm. 



Oahu: Waianae Mts., back of Leilehua (Cooke). 



Somewhat related to L. pulchra but with fewer whorls. 

 L. captiosa is broader in proportion to its length. This 

 species is also related to L. fuscula Gul. The spire is how- 

 ever, more convex, and the surface is smoother.
