Fishes of Upper Georgia. 309 



scribed species. They are so small and fragile that the fin 

 formulae, and some other characters, cannot easily be made 

 out; but I find no discrepancy between the characters shown 

 by my specimens and those noted in Girard's brief descrip- 

 tion. 



My specimens are short, chubby, and compressed, bearing 

 some resemblance in form to Microperca punctulata. The 

 mouth is moderate, with equal jaws : the two dorsal fins 

 about equal, and distinctly separated by an interspace. The 

 scales are comparatively large, but apparently quite variable, 

 the number of transverse scries varying from 42 to 56. The 

 lateral line traverses the scales of the operculum, and ends 

 about midway of the body, being distinct on from 13 to 30 

 scales. This is also quite variable, one side of the same 

 specimen often having twice as long a lateral line as the 

 other. Lateral line arched high over the pectorals, running 

 parallel with the elevated and rounded nuchal region. 



Head 3| in length (without caudal, as in all cases in the present paper) : 

 depth A'\. Eye :'. in head. Fin rays, 1). X, 13, or IX, 12 or 13. A. II, 7, or 

 II, 8. Scales, 42, 41, 44, -14, 40, 48, 55, 56, in as many specimens, those 

 with the most scales usually having the lateral line continued farthest. 



Color greenish, with dark specks: litis mottled: a dark line forward 

 from eye. 



Length of specimens examined a little less than an inch. They prob- 

 ably reach a somewhat larger size. 



Habitat. Mill ponds in the Etowah water basin. Most 

 of my specimens taken in Djke's Pond, near liume, Ga., 

 with JJoleusoma stigmceum and Mimiilus lints.
