seldom found where there is a dense vegetation, the limit being at 

 the thick growths of the "Stag-horn fern" {Gleichcnia dichotoma) 

 and leie {Freycinetia Arnotti) . The elevation at which it is found is 

 from about 1000 ft. to about 1400 ft. Of the shells found 95.5 per 

 cent, were on either lehua, straussia or guava. Lehua represents 

 53.3 per cent, of the trees on which shells were found, straussia 

 9.8 percent., and guava 29.8 per cent. Of A. viultizonata 54.6 per 

 cent, were found on lehua, 14.2 percent, on straussia, and 26.7 per 

 cent, guava. Of the remaining plants Pa;deria foetida, representing 

 1.7 per cent., yielded 1.2 per cent, of the shells ; Kadica, represent- 

 ing 2.3 per cent., yielded 1.2 per cent.; and all others, about a half 

 a dozen genera, representing 3.1 per cent., yielded 2.1 per cent. 

 The distribution of the.se plants, according to sub-ridges, and of 

 the color-varieties found on these plants may be found in Tables 

 II and III. 



Achatinella multi^onata Baldwin.' 



'•'vShell dextral, imperforate, moderately solid, elongately coni- 

 cal, apex sub-acute, surface shining, striated with fine lines of 

 growth, under a strong lens showing very numerous, extremel}^ 

 minute decussating strice ; apical whorls smooth, scarcely decus- 

 sated. Color white, variously striped with numerous dark brown 

 lines and bands, some on the base and others spiral. Whorls 6, 

 lightly marginate above, convex ; suture lightly impressed. Aper- 

 ture oblique, oval, white, the dark bands of the exterior visible 

 within; peristome acute, thickened within, slightly expanded, 

 white, the dark lines of the exterior marked on the inner edge; 

 columella purplish brown, terminating in a strong, oblique, tortu- 

 ous fold. Length, 18; diam., 10 mm. Habitat, Nuuanu valley, 

 Oahu. Animal when extended in motion, longer than the shell. 

 Mantle brown, lighter on the outer edge. Foot above and below 

 light brown, posterior portion tapering. Tentacles long and slen- 

 der ; these, with the head above, slate color." 



The above is Mr. Baldwin's description of A. niultizonata. 

 Mr. Baldwin states that the mantle is brown. In all the specimens 

 collected by the writer the mantle varies from a very dark to a light 

 slate color. It is sometimes mottled with light or dark markings. 

 A. ))iuUizonata, in common with most of the arboreal achatinellidae,
