66. Zygonectes melanops (Cope) Jordan. Black-eyed Top Minnow. 

 (M. V. 264.) 



Numerous specimens of this species were obtained by Professor 

 Forbes in the streams and ponds of the southern part of the state. 

 They agree exactly with Prof. Cope's description of his Haplo- 

 cJtilus melanops from the Neuse River in North Carolina. The 

 wide distribution of this species is rather unexpected. Cache R.
