CATALOGUE OF VERTEBRATES. 727 



"Ichthelis rubioauda. River Sunfish. 



" This beautiful fish is distinguishable by its ruddy tail and 

 lower fins. It attains a greater size than the others, and is met 

 with most usually in the rivers. In the Delaware they are 

 abundant, and reach a length of several inches very frequently. 



"Pomotia appendix. Black-eared Sunfish. 



" This species is larger bodied and much less brilliantly col- 

 ored, but in its habits is in all respects similar to the next. It is 

 less abundant than the next, and like it, prefers quiet ponds and 

 slowly-moving streams to the river or tide water. The black 

 appendix easily distinguishes it from the following. As articles 

 of food the two species are of very little value."
