168 ACHATINELLA ELEGANS. 



-band. The lip is sometimes white, more often fleshy -'brown 

 or darker. The white band below the suture sometimes runs 

 to the very apex, as in A. b. spadicea, but oftener not. The 

 early whorls are usually dull-brown. Dextral shells largely 

 prevail, but all of the color-forms are common to both dextral 

 and sinistral. In one lot from Hauula there are 82 dextral, 

 23 sdnistral shells. 



A set of 8 from Kahuku are very solid, coarsely streaked 

 throughout, without bands (pi. 32, fig. 15, coll. by Gulick). 



An unusual color-form, pi. 28, fig. 13c, has a pattern re- 

 sembling some specimen's of oomorpha or obliqua somewhat. 

 The streaking of elegans is only weakly shown, in places on 

 the spire. The sutural white line runs to the apex, as in 

 spadicea and some specimens of elegans. In its compact 

 shape this shell is similar to several 'characteristically streaked 

 elegans in the same Hauula lot. It is obviously an extreme 

 form of elegans. 



Color-variety inelegans n. var. PL 33, fig. 12. The shell is 

 dextral, rather thin; glossy, rather distinctly striated spir- 

 ally to the last whorl, which is smoother. Embryonic whorls 

 corneous, following whorls cinnamon with white sutural 

 'border, last whorl pale cinnamon, shading to darker at the 

 base, and having two orange-cinnamon bands, one above, 

 the other below the periphery ; sutural band pure white, be- 

 ginning on the third whorl. Peristome a little expanded ait 

 base, very little thickened within, edged with dark-brown. 

 Golumellar fold weak, whitish. Length 19, diam. 10, aperture 

 9.5 mm. ; 6 whorls. 



Kaliuwaa, J. T. Gulick, no. 92504 A. N. S. P. 



This shell was labeled A. spadicea by Mr. Gulick, but it is, 

 in my opinion, a form of the elegans stock with less modified 

 coloration than elegans. It does not seem closely related to 

 the Bulimellas of upper Kaliuwaa, above the falls.
