322 AMASTBA. 



The Uranie visited Hawaii in August, 1819. Some time 

 was spent in Kailua Bay, near the middle of the west coast, 

 where Gaimard, the surgeon-naturalist, explored the neigh- 

 borhood. A second stop was made further up the coast at 

 Kawaihae Harbor in Kohala district. Whether Amastra ex- 

 tends down the west coast to Kailua or Mt. Hualalai is not 

 known, but it certainly occurs in the Kohala mountains. I 

 suspect that A. luteola was procured in that region. It should 

 be looked for on the western slopes of the Kohala Mts., 

 towards Kawaihae. 



I cannot endorse Borcherding's contention that luteola is 

 a dextral Laminella citrina. The shape of the shell is en- 

 tirely different. Moreover, the Uranie did not visit Molokai, 

 but only Hawaii and Oahu. 



114. A. PEASEI Smith. PL 49, fig. 11. 



" Shell dextral, globosely ovate-conic, subperforate, a little 

 glossy, lightly striated with lines of growth, covered with a 

 very thin epidermis. Whorls 6, the first four reddish-brown, 

 a little convex, penultimate whorl large, inflated, and paler 

 like the last whorl; the spire passes abruptly into a cone 

 above the penult, whorl. Suture simple. Aperture small, 

 not as long as the spire, subquadrate, reddish inside. Peris- 

 tome thin ; columella straight, slightly reflexed, nearly cover- 

 ing the small umbilical crevice, provided with a thin, sub- 

 basal fold, and joined to the lip by a very thin callus. Length 

 17, diam. 10 mm. 



" Var. &. Spire almost straightly conic " (Smith).

II Remarkable for the large size of the penultimate whorl " 

 (Smith). 



We have not seen this species. It may be a Lanai shell re- 

 lated to A. aurostoma, but it also seems not unlike A. in flat a 

 of Oahu.
