3—4, Proreus. Spec. 1. 
limedracus, (mud-dragon,) spotted, having a purple 
ruffie, or suit of gills, around the neck. After 
reading Dr. Mitchell’s article on the subject in 
Silliman’s Journal, the article in Cuvier, and in 
Long’s Expedition, I have not been able to find 
any settled specific name for the Lake Erie 
Proteus. Ihave therefore adopted one for our 
students, as we have two elegant specimens in 
our collection——one presented by Mrs. General 
Porter, and the other by Maj. Frazer, of Black 
Rock. The former is seven, and the latter 
fourteen inches in length.
