Remarks. — This is a very distinct and remarkable species. Although many 

 individuals differ, the prevailing character is to have the whole of the whorls 

 covered with numerous granulate, revolving lines, generally bearing a purple 

 or brown line. In some the tubercles of the carina assume the character of 

 folds. 



Melania catenoides. Plate 6, Fig. 60.

Hab. Chattahoochee River, Columbus, Geo. Dr. Boykin. 



My Cabinet. 

 Diam. .43, Length .93 of an inch. 



Remarhs. — This species differs from the M. BoyMniana, in being without 

 tubercles and carina. The coloured revolving hair-like lines are numerous, and 

 being pitted, present the appearance of a chain. Some of the old specimens are 

 quite black, while the younger ones are green or yellow. In some cases where 

 the apex is eroded or worn off and the shell black and old, it looks like M. Vir- 

 ginica, (Say,) as no grains can be observed.
