Head 4|; depth 4f to 5 ; eye large, 3^. D. 8; A. 11 ; scales 7-40-3; 

 teeth 2, 4-4, 2. Close to Notropis dilectus, but the lateral line more 

 decurved, the scales a little smaller, and the sides with a dark band. 

 Body slender, greatly compressed, the outlines gently arched ; snout 

 pointed, shorter than eye; lower jaw somewhat projecting; maxillafy 



* This nominal species is probably identical with N. lUleetus. The following description istaken 

 from 3 specimens 2'J4 inches long, collected in Pearl River, Jackson, Miss., by Dr. 0. P. Hay: 



Body long and slender. Maxillary scarcely reachingfront of orbit. Front of dorsal equidistant 

 between snout ami concavity of caudal. Eye 3 in head, equal to interorbital space. Mandible 

 projecting slightly, its tip, when closed, opposite middle of pupil. Lateral lino decurved; 17 

 scales in front of dorsal. Dorsal fin high, its highest rays equal to head. Color pale, the sides 

 bright silvery ; a row of dots along base of anal. Head 434 > depth 5 or6. D. 11 ; A. 12. Scales
