 white, variegated and reticulated with brown, covered 

 with a thin fulvous epidermis, the first few whorls 

 smooth, the rest longitudinally ribbed, the last spi- 

 rally grooved below ; aperture rather small, oblong, 

 columella slightly arched, lip thickened, varicose,

Hab. Guacamayo, Central America (found in sandy mud); 

 Cuming. 



This species, as its name truly denotes, is the most ele- 

 gant of the genus. Of solid growth, tapering sharply to 

 the apex, the whorls are ribbed with peculiar lightness 

 and regularity, and the main generic character of the 

 genus — the inner teeth of the lip— is unusually strongly 

 developed.
