Shell sinistral, sometimes perforate, ovate-conic, solid, shin- 

 ing, finely striated, microscopically very minutely and faintlv de- 

 cussated, white, with brown bands; apex subacute, white, with a 

 brown line above the suture; spire regularly conical; whorls 6 or 

 7, convex, not margined; the last rounded, equal to 65-100 of the 

 length ; columellar fold white, superior slightly developed, moder- 

 ately twisted ; aperture somewhat oblique, roundly oval, white 

 within; the bands sometimes appear in pale brownish stripes on 

 the inner surface; peristome white, slightly thickened, subreflecled

Length of aperture 0.39 in. (10 mill.). 



Average weight 6.80 grains, greatest weight 9.00 grains, least 

 weight 6.00 grains. 



Var. B. Thicker and more elongate, with dark brown or 

 black bands; lip well thickened within and deeph' colored on the 

 edge opposite the bands; columella slightly toothed.

 0.40 in.

Remarks. Has been confounded with A. tappaniana and A. 

 splcndida Xewc, but is smaller than the former, with fainter sculp- 

 turing and more regular conical spire; it also differs in its dark 

 bands, rounded body whorl, less refledled lip, and slight columellar 

 fold. It resembles A. splendida Newc. in its brown bands, but is 

 otherwise quite distinct. A nuclear characfter which distinguishes 

 it from either of the above is the spiral line on the first whorls. — Gk.
