346 Fishes of Upper Georgia. 



My specimens of this species from the Etowah agree 

 closely with each other, and differ somewhat from northern 

 specimens. The southern form is, perhaps, a recognizable 

 variety, which may be termed etowanus. 



This form may be characterized as follows : — 



Head shortish, 4. 1 5 - to 41 in length; eye moderate, about as in nigricans. 

 Form, scales, etc., as in var. nigricans. Lat. 1., 48. D. uniformly I, 10. 

 A., 1, 7. V., 9. Pectorals shorter and broader than in nigricans, 4£ to 5 

 in length of body. 



Body nearly black above, the color running down on the sides, and 

 changing abruptly into the silvery hue of the belly. A whitish spot at 

 the base of each scale, — these forming conspicuous pale streaks along 

 the rows of scales. Dorsal black edged ; other fins decidedly red in life. 



Habited. Water basin of the Etowah and Oostanaula, 

 abounding in rapids and clear places. Known as Hog-molly 

 (Mullet), Crawl-a-bottom, and Hog Sucker. 



A number of specimens of this variety, compared with 

 nigricans of the same size, show the following differences : — 



* D. I, 11 ; head long (4i in length) ; pectorals long; 4 to 4^- 

 in length of body; lower fins olivaceous or dull orange; 

 colors relatively dull ; scales without streaks. Northern. 

 NIGRICANS. 



** D. I, 10; head shorter (4.^) ; pectorals shorter (4^) ; lower 

 fins red; colors brighter; pale stripes along the rows 

 scales. Southern etowanus.
