AMASTRA. 43 



Gulick's localities are very trustworthy, but we would like 

 to see that of A. conifera verified. 



A. b. kahakuloensis P. & C., n. subsp., pi. 8, figs. 5, 6. An- 

 other form of baldwiniana taken at Kahakuloa, W. Maui by 

 Mr. Thaanum, is much more slender than any from Olowalu. 

 A keel is generally visible above the suture towards its end, 

 and there is sometimes a little malleation. The mummy 

 brown cuticle is conspicuously streaked with whitish and on 

 the last half whorl with black or blackish. The surface under 

 it is pinkish buff or almost white. 



Length 17, diam. 8.5, aperture 7 mm. ; 6y 2 whorls. 



Length 16.5, diam. 9, aperture 8 mm. 



A. AFFINIS (Newc.). PI. 6, figs. 12 to 19. 



Vol. XXI, p. 297. A large series recently collected by Mr. 

 Thaanum in the Polipoli Forest Reserve, Kula district (pi. 

 6, figs. 15 to 19) shows great variation. The shape varies be- 

 tween length 15.2, diam. 7.3 mm. and 13 x 7.3 mm. The 

 ground color may be light buff, ochraceous buff, buff-pink 

 Prussian red, purple-drab, or various more neutral tints. 

 Some shells are pale below as in Vol. XXI, pi. 44, fig. 8. 

 The outer thin cuticle is usually figured in zigzag-netted 

 pattern, often wholly absent. 



In Auwahi (pi. 6, figs. 12, 13, 14), a couple of miles from 

 Polipoli, the shells have mainly a dull or dead appearance, 

 with the cuticle largely deciduous, what remains being usually 

 dense and opaque, as in Gulick's rustica. 



It seems obvious from these lots that the supposed sub- 

 species or varieties pupoidea, bigener, bigener abberans, sub- 

 pulla and Cinderella are merely mutants of affinis, and with- 

 out racial significance. 



A. LAHAINANA P. & C., n. Sp. PI. 6, figS. 1 to 10. 



The shell is perforate or closed, ovate-conic, thin but rather 

 strong, not glossy, having rather coarse growth-striae near 

 the suture, elsewhere weak. Color variable : carob brown, 

 russet, apricot buff, ochraceous buff, or nearly white ; some- 

 times the color is bipartite, light with a dark base or light
