SYNONYMS AND REFERENCES.

 p. 57. 



DESCRIPTION. 



Shell "regularly oval, rather elevated; with 

 numerous radiating prominent lines; apex very 

 prominent, inclined, eroded, not nearly central." 



OBSERVATIONS. 



Found by Mr. Conrad in Blackwarrior river, 

 south of Blount's springs, Alabama, attached to 

 species of Melania. It is readily distinguished 

 by the elevated radiating lines. Not having a 

 specimen, I give it only a provisional place in 

 this genus.
