3 4. PROTEUS. Spec. 1, 



limodracus, (mud-dragon,) spotted, havinga purple 

 ruffle, 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. I have 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,
