angles, b}- very fine, close, forwardh--descending wrinkles. Color 

 light brownish-red, darker on the spire, interspersed with irregular, 

 zigzag yellowish white flanimules forming spots on the periphery, 

 and absent on the base except close to the callus. Apex some- 

 what obtuse. Suture simple, well impressed. Whorls about 3^, 

 quite convex, slightly projecting above the suture, the embryonic 

 nearh- smooth, the last somewhat flattened above and below the 

 rounded periphery, not descending in front. Aperture nearly 

 semicircular; outer lip thin. Callus whitish about the axis, the 

 rest transparent, thin, granular. Operculum punctate, of a light 

 cinnamon color. Maj. diam. 4.9, total length 3.6 mm. 



Kauai: Olokele (type loc), Waiakoali (Cooke). 



Type No. 14,905, Bishop Museum. 



This species has nearly the same form as //. rotelloidea Migh. 

 It is easily distinguished by its larger size, the absence of spiral 

 striae, and the peculiar sculpture of the forwardly descending 

 wrinkles over the growth lines. 



Helicina kauaiensis, n. sp. 



. Fi<>:. 8. 



The shell is subglobose-conic, with the periphery well rounded, 

 quite thin, nearly smooth, under a lens minutely striate with lines 

 of growth, with several (in the type specimen about eight) widely 

 spaced, thin, raised spiral cuticular striae, three above, one on, 

 and the rest below the periphery, the upper striae extended on the 

 spire nearly to the embryonic whorls. Color orange-red, with 

 distinct light yellow flammules at and above the periphery. Spire 

 convexly conical, with the apex slightly acute. Suture simple, 

 well impressed. Whorls 3^, distinctly convex, under a lens the 

 embryonic whorls are transversely striate, the last rounded, not 

 descending in front. Aperture slightly oblique, .semicircular, not 

 contracted ; outer lip thin. Callus slightly whitish about the axis, 

 the rest very thin, transparent, very minutely punctate. Maj. 

 diam. 3.2, total length 2.4 mm. 



Kauai : The upper part of Milolii (Cooke). 



Type No. 14,906, Bishop Museum. 



This species recalls //. rotelloidea Migh. , in form. It is slightly 

 larger, darker colored, with more distinct flammules, higher spire, 

 and is also distinctly marked with spiral cuticular stride.
