Shell rather small, depressed-glohular, not very thin, 

 scarcely at all shining ; not translucent, of a squalid white, 

 cream colour, or cinereous, with spiral bands of various 

 shades of brown, which are frequently interrupted, and 

 vary much in number and intensity ; the body in general 

 adorned with a subcentral, and for the most part broadish 

 band (either interrupted or entire), which winds along the 

 base of the lesser volutions likewise ; besides which from 

 three to five fillets, at times rather indistinct ones, encircle 

 the lower disk; occasionally the shell is brown, with a 

 white edging below the dark upper band, and is speckled 

 underneath with white ; entire exterior marked leng-th- 

 ways with crowded costellar wrinkles. Spire a little 

 raised ; apex rather blunt, darkish or pellucid. Whorls 

 six, convex, tolerably broad, not suddenly enlarging ; the 

 body not deflected, more or less subangulated at the 

 circmnference. Aperture abbreviatedly lunate, only equal 

 to two-fifths the total diameter, nearly as high as broad. 

 Peristome, strongly ribbed internally with white fulvous
