Description. — Shell conic, nearlj'- smooth; spire elevated; whorls 

 about nine, flat, with two fine, distant, brown lines on each, the lower 

 one revolving upon an angle near the suture ; lines obso- 

 lete on the extreme upper whorls and increased to four or 

 five on the body- whorl visible also within the aperture ; 

 sutures deeply impressed ; aperture ovate, within whitish, 

 but exhibiting also the brown lines of the epidermis ; 

 columella curved, sinus inconspicuous. 



Habitat. — Alabama. 



Diameter, -32 of an inch (8 raillim.); length, -86 of an 

 inch (22 millim.). Length of aperture, -33 of an inch (8 millim.) ; 

 breadth of aperture, -16 inch (4 millim.). 



Observations. — May be compared with 31. Taitiana, Lea, but may be 

 distinguished by its flat subangulated whorls. It also exhibits some- 

 what coarse striae (amounting nearly, if not quite, to ribs in some 

 specimens) upon all the whorls ; even the body- whorl is no exception.. 

 The sutures also are deeply impressed, the contiguous whorls shelving 

 towards each other to form quite a furrow there. Upper whorls car- 

 inate. It is a very beautiful species, the distinct reddish-brown, hair- 

 like bands contrasting finely with the yellowish-brown color of the 

 general shell. — Anthony.
