70. L. CONSPICIENDA n. sp. PI. 11, fig. 10. 



The shell is imperforate, elongately conic, straw color, 

 rather thin for a shell of its size, very glossy, nearly smooth, 

 under a lens minutely and irregularly striate with lines of 

 growth. Spire narrowly conic, apex somewhat acute. 

 Suture simple, slightly impressed. Whorls 6%, slightly con- 

 vex, at first increasing slowly and regularly, the penultimate 

 increasing more rapidly, the last long, subcylindrical, tapering 

 slowly to the base, ascending slightly in front. Aperture 

 subpyriform, hardly oblique, perpendicular, white within. 

 Columella nearly straight, with a thickened oblique median 

 fold, and with scarcely any thickening along its face. Outer 

 lip very slightly arcuate, faintly thickened within ; columellar 

 margin thin, appressed, adnate ; parietal margin covered with 

 a thin colorless callus. Length 12.3, diam. 5.6, length of

L. kuhnsi, from the same locality and from which it is easily 

 distinct, is probably its nearest relative from the island of 

 Maui. L. compicienda is more nearly related to L. perkinsi, 

 Sykes, from the island of Lanai. It has, however, a more 

 acute apex, the spire is less regularly conic, the whorls are 

 more convex, the aperture is narrower and more elongate and 

 the columella is longer and straighter.

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

 lens slightly striate, brownish, smooth, semipellucid, apex 

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

 pressed; whorls 6-61/2, flatly convex, the last equal to two- 

 thirds the length of the shell; aperture pyriform; lip with 

 dextral margin slightly thickened, whitish corneous within, 

 columellar margin narrow, parietal margin lacking. Length 

 10.5, diam. max. 5 mm." (Sykes.)
