486. NOTROPIS ARGE (Cope). 



Head 4; depth 6; eye 2f to 3. D. 8; A. 11; scales 5-39-3. Close to 

 N. atherinoides but the eye very large, longer than snout ; lateral line 

 nearly straight, head large, the snout not very blunt ; mouth large, the 

 chin projecting. Pale greenish, the silvery band on sides bounded by a 

 blackish line ; a dark vertebral streak. Length 3i inches. Upper Wabash 

 Valley, southern Michigan, Green River, Kentucky, etc.; slenderer than 

 the usual atherinoides, the eye much larger, but apparently varying into 

 the latter, hence of doubtful validity, (apyrjj shining white.)

Head 4| ; depth 4f ; eye 3. D. 8; A. 11 ; scales 7-38-3 ; teeth 2, 4-4, 2. 

 Body elongate, compressed, but a little deeper and more compressed, with 

 blunter snout ; eye large, larger than snout ; mouth oblique, smaller than 

 in related species, the jaws subequal, the maxillary 3i in head, reaching 

 eye. Colors very pale; silvery, snout and bases of fins rosy; a row of 

 black dots above base of anal ; young often finely speckled. Length 3

488. NOTROPIS FUMEUS, Evermann. 



Head 4; depth 4$ 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; maxillary 



* This nominal species is probably identical with N. dilectus. The following description is taken 

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



Body long andslender. Maxillary scarcely reaching front of orbit. Front of dorsal equidistant 

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

 projecting slightly, its tip, when closed, opposite middle of pupil. Lateral line 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 4> ; depth 5 or 6. D. 11 ; A. 12. Scales
