ACHATINELLA PULCHERRIMA. 143 



According to a note from Mr. Sp'alding, melanostoma is 

 now found only in the northern 'branch of Kipapa,; but I do 

 not know just what form he found so far east. 



A. multicolor Pfr., PI. 30, fig. 11, reproduction of original 

 figure. " Shell dextral or sinistral, imperf orate, conic- 

 oblong, solid, striate, and under the lens most minutely de- 

 cussated, glossy; buff or whitish, variously ornamented with 

 blackish-chestnut bands, rarely uni colored. Spire long-conic, 

 towards the apex somewhat attenuated, rather acute; suture 

 margined. Whorls 6, rather flat, the last about two-fifths the 

 total length, rounded basally. Aperture oblique, truncate in- 

 verted ear-shaped; columellar fold above, strong, twisted. 

 Peristome black-edged, the outer margin somewhat straight- 

 ened, narrowly expanded; columellar margin dilated, sub- 

 a dilate. Length 17, diam. 9 mm., aperture 8% mm. long, 4% 

 wide. Sandwich Is., Frick in Cuming coll. (Pfr.). 



In the above description Pfeiffer obviously confused two 

 species. His two figures, reproduced in my pi. 30, figs. 11, 

 lla, belong to A. pulcherrima (fig. 11) and A. soiuerbyana 

 oviformis (fig. lla). Doctor Hartman recognized the latter 

 and added A. oviformis to the synonymy of multicolor; but 

 he included Pfeaffer's fig. 11, and therefore did not restrict 

 the species or realize its dual composition (Proc. A. N. S. 

 Phila. 1888, p. 30). Mr. Sykes referred Pfeiffer 's fig. lla to 

 A. oviformis, 'and fig. 11 to A. recta Newc., which he ranks as 

 a variety of A. byronii. As several of Pfeiffer's phrases, par- 

 ticularly "perist. nigrolimbatum' apply best to his dextral 

 shell, I would restrict A. multicolor to fig 11. It becomes 

 therefore an absolute synonym of A. pulcherrima, having the 

 typical color-pattern, which seems to have been more common 

 in the lower forests of three-quarters of a century ago than 

 it is now. A. recta Newc., which Mr. Sykes and others have 

 confused with the present group, belongs in the series of A. 

 livida. 



Form mahogani Gulick (pi. 27, figs, 4 to 4<i, Ahonui). This 

 form has the smooth surface of A. pulcherrima, merely marked 

 with growth-lines, not corrugated or wrinkled. A subsutural 

 dark band is often wanting, or not darker than the rest of the
