Makiki, either mauka or makai, but some Palolo specimens 

 have the coloration described.

" Shell dextral or sinistral, imperf orate, acuminately ob-

 streaked and waved with brown, with several interrupted 

 brown bands on the upper parts of the whorls; apex some- 

 what obtuse ; spire convexly conical ; suture margined, mod- 

 erately impressed; whorls 6, convex; columellar fold central, 

 white, strong; aperture truncately auriform, white within, 

 a little oblique, in sinistral specimens very oblique ; peri- 

 stome thickened within; with external margin unreflected, 

 compressed, edged with brown; columellar margin dilated, 

 adnate; parietal margin wanting. Length 20%, breadth 10, 

 length of body- whorl 15 mm. Average weight 8.6 grains.' 

 (Gulick.) 



Var. b, rich brown, with light streaks and waves. Var. 

 c, yellow at the base, with one or more brown bands above. 

 Var. d, yellow at the base and white above, without bands. 

 Var. e, nearly pure white. Var. f, ash or yellow gray, with-

Achatinella versipellis GULICK, Ann. Lye. N. H. of N. Y., 

 vi, p. 224, pi. 7, f. 44a, b. December, 1856. Achatinellastrum 

 versipilis Gul., PEASE, P. Z. S., 1869, p. 646. Achatinella 

 fuscolineata SMITH, P. Z. S., 1873, p. 75, pi. 9, f. 2, and var. 

 6, f. 2a. 



Very closely related to the plumata and various other pat- 

 terns of A. fulgens, from which versipellis is separated mainly 

 by its habitat, on the north side of the main range, and by 

 the frequency of dextral shells. There is, however, some dif- 

 ference in the patterns; versipellis often having the ground 

 color of the last whorl all yellow.
