are elongate, slender and simple. The premaxillaries are a little projectile ; 

 extremity of maxillary acuminate. The first dorsal commences at a point 

 mid-way between the basis of tlie tail and the anterior margin of the orbit, 

 or opposite the 3-4th anal radii. The second dorsal commences above a 

 point a little in front of the middle of the anal. Radii D. IV. 10; A. I. 

 22-3; V. I. 5; P. 12. The scales are small, in 14 longitudinal, and 75 

 transverse series. 



In life this fish is translncent, with a silver band on each side, which 

 covers one scale and two halves, and is lead-edged above. The dorsal re- 

 gion and top of head are dusted minutely with black. OpercuKim and 

 cheek silverv.

This little fish I took in great abundance in Coal Creek, a tributary of 

 the Clinch, in East Tennessee. It was very abundant, and easily caught 

 in rather sluggish water. The stream named passing tlirough a limestone 

 region, is liable to partial desiccation in the Autumn, and in several pools, 

 thus formed, I obtained this species. 



In the original description I gave D. V., which should probably be as 

 here stated, D. IV.

I refer the following species to this genus, without going into its syn- 

 onymy, following the arrangement given by Grlinther in the Catalogue of 

 the British Museum. In consideration of the peculiar views of this au- 

 thor respecting specific and generic characters, I consider this a tempo- 

 rary arrangement, to be rectified by a more thorough analysis of the 

 subject at some future time.*

Stout; head four times in length to basis caudal ; orbit four times in length of head, and twice 

 in Inter-orbital width. Depth 3.75 times in length. Anal fin commencing about opposite the 

 middle of the dorsal. Cheek scaly, operculum smooth. Scales of body in. 36 transverse, and 13 

 longitudinal series. Eadii D. 12, A. JU or J 1, extending more than half way from basis of first ray 

 to basis caudal. Length of female, four inches. Color uniform light brown, yellowish below. 



Most of the specimens of this species (seven) are females, and in them the oviducts are pro- 

 longed in a tube to near the extremity of the first ray of the anal fin. Several have many well 

 developed eggs in the former. Small, faintly cross-banded specimens, perhaps males, do not pre-
