indented and curved at base, where there is a small but 

 rather broad sinus. 

 Habitat. — Alabama. 



Observations. — The colors in this species are finely con- 

 trasted, and the genei-al appearance is very lively and 

 pleasing ; the bands on the body-whorl are not uniformly 

 distributed, the upper and lower ones being widely separated, while 

 the central ones are very close together and less distinct. Altogether 

 it is one of our most beautiful species. — Anthony.
