very perceptible on the inferior whorls ; above tumid, and 

 ornamented with a series of roundish white spots, placed 

 somewhat distant and doubled on the last whorl ; aperture 

 squarish, and with a short but decided canal; columella 

 naked, twisted, and with a sharp margin. A thin epidermis 

 covers many individuals.

Testa subulata, leevigata, polita ; anfractibus superne sulco 

 impresso divisis, infra longitrorsum plicatis, interstitiis laevi- 

 gatis, medio saturate castaneis, inferne albis ; cingulo tuber- 

 culato, albido ; anfractu ultimo fasciato ; columella contorta 

 elongata. 



An elegant glittering species, well distinguished by its 

 ornation, though scarcely by its sculpture. The area above 

 the girdling is white, sometimes of a pale brown ; beneath, 

 and in the midle of each whorl, of a dark chesnut ; and a 

 narrow portion just above the suture is of a clear milk 

 white, and the last whorl is similarly banded. A very dis- 

 tinct canal exists. The pale individual figured has most 

 probably lost its colour.

The superior portion of each whorl is rather contracted, 

 and here it is provided with two series of small rounded tuber- 

 cles ; the lower of the two is white, and from each originates 

 a slightly arched fold. The last whorl has a conspicuous 

 white band, with a dark brown base.
