302 AMASTRA, MAUI. 



what thickened within. Columellar fold rather sharp. The 

 spire has nearly straight outlines, whorls but slightly convex. 



Length 12, diam. 6.7, aperture 5 mm. ; whorls 6*4. 



Length 11.2, diam. 6.6, aperture 5.4 mm. 



" Animal when extended in motion as long as the shell. 

 Mantle light brown. Foot above and below brown with spots 

 of deeper shade on the sides. Tentacles and front above al- 

 most black " (Baldwin). 



East Maui : Makawao. Common, but very local in its dis- 

 tribution, in a belt of forest land about 4,000 feet above sea 

 level (Baldwin). 



Amastra nana BALDWIN, Proc. A. N. S., Phila., 1895, p. 

 232, pi. 11, figs. 48, 49. 



Shorter, thinner, less calcareous and darker than A. ajfinis, 

 and much smaller than A. a. kaupakaluana, which occurs 

 farther north. The description and figures are from the 

 types, no. 65718, A. N. S. P. 



The color pattern varies within wide limits, as shown by 

 the figures. 



There is in the Boston Society collection a shell, no 13423, 

 said to be from Molokai, which Hyatt described in MS. as a 

 new species, but which seems to me to be identical with nana. 

 The shell (pi. 42, fig. 1) is subrimate, thin, ovate-conic, not 

 shining; outlines of the spire straight. Embryonic whorls 

 flat, strongly costate and conspicuously carinate, purplish- 

 brown. Following whorls very slightly convex, marked with 

 rather distinct wrinkles of growth, reddish-brown under a 

 thin pale-brown cuticle which is profusely but indistinctly 

 marked with abruptly-waved longitudinal stripes of reddish- 

 chestnut, fading at their edges. Last whorl well rounded at 

 the periphery. Aperture dark within, the lip thin. Length 

 9.2, diam. 5.8, aperture 4.9 mm.; 5% whorls. The locality 

 assigned seems to me doubtful, but the description and figure 

 are inserted to call attention to the matter.
