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

 the thick growths of the "Stag-horn fern" {Glcichenia diclwtonia) 

 and leie {Frcvciiietia 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. lychua 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. multizoiiata 54.6 per 

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

 cent, guava. Of the remaining plants Po'dn^ia fa'tida , representing 

 1.7 per cent., yielded 1.2 per cent, of the shells; A'ad/ni, 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 these plants, according to sub-ridges, and of 

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

 II and III. 



Achatinella multi^jonata Baldwin.' 



"Shell dextral, imperforate, moderately solid, elongately coni- 

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

 growth, under a. strong lens showing ver}' numerous, extremel}^ 

 minute decussating striae ; 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. i)niltirjo)iata. 

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

 coUecled by the writer the mantle varies from a ver}- dark to a light 

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

 A. vndtizonata, in common with most of the arboreal achatinellidae,
