Acliatiiia fasciata, Mullek. — Shell imperforate, conical, rather 

 thick, smooth, shining, minutely striated ; whirls seven to eight, convex, 

 decreasing in diameter gradually and regularly from the body-whirl to the 

 apex ; suture impressed ; apex obtuse, commonly 

 white, sometimes rosy ; aperture suboval, purely 

 white internally, sometimes with a thickened ridge 

 within, and parallel to the peristome ; peristome 

 acute, sometimes crcnate ; columellar margin with 

 a thin callus, sometimes rosy ; columella sub- 

 truncate in the young, entire in the mature shell, 

 imperforate ; surface beautifully variegated with 

 broad, entire or interrupted bands, lines, and spots 

 of brown, with bands and lines of green and yellow, 

 and with lines of rufous, revolving upon the whirls 

 from the apex to the aperture, but more distinct 

 upon the outer whirls ; a single system of coloring 

 prevails in some shells, while in others there is a 

 mingling of all of them upon the same specimen.
