with a white band on the periphery of the last whorl; apex sub-

 6J, very convex. Columellar fold central, white, strong. Aper-

 slightly detached; parietal margin wanting. Length 23, breadth

Achatinella plumbea GUL., Ann. Lye. N. H. of N. Y., iv, p. 

 213, pi. 7, f. 39, 1856. 



Very closely related to marmorata, perhaps not always dis- 

 tinguishable, but polished, typically belted with white, the 

 band rarely wanting, and without the special marking of mar- 

 morata. The typical form from Gulick (pi. 10, figs. 9, 10) is 

 usually speckled on the spire with white on a fawn-brown 

 ground. A lot from Baldwin, also from Kula (pi. 10, figs. 11, 

 12) is drab with darker and lighter streaks, the shell smaller. 

 Another lot from Baldwin, locality not stated, is fawn with 

 narrow brown streaking, with or without a belt, sometimes with 

 some scattered whitish dots (fig. 8). 



Large specimens from Gulick measure 25 mm. long, 14.5 wide. 

 The smaller drab form is 22.5 x 12 mm. 



20. P. WINNIEI Baldwin. PI. 13, figs. 1, 2, 3. 



Shell sinistral, subperforate, rather thin but moderately 

 strong, long-conic, somewhat glossy. First 1^ or 2 whorls of 

 the embryonic shell flesh-colored, next half whorl boldly 

 marked with broad brown and white axial stripes. Following 

 neanic and adult whorls cream-white, copiously striped with 

 dark chestnut, the stripes more or less irregular and unequal. 

 Growth-lines and spiral sculpture rather weak. A sutural mar-
