A single small specimen was obtained at Macon. All the names 
cited above belong to varieties of the same species. DeKay mentions 
that this species occurs at New Orleans.

Many fine specimens of this species were taken. I have them from 
Corinth, Artesia, Macon, and Enterprise. This and the succeeding 
species are seen almost everywhere, especially in quiet waters, swim- 
ming near the surface. One of my specimens from Enterprise is 5 
inches long to the caudal, or a total of 35 inches. 
The color is translucent yellowish green above, silvery white below, 
with a broad, dentate, lateral band of black. There are four or five 
longitudinal rows of black dots above the lateral band, especially con- 
spicuous in specimens from Enterprise. The fins are golden, the dorsal 
and caudal dotted with black.

Many of these little fishes were seined in the ponds and rivulets along 
Catawba Creek in the vicinity of Artesia, and in Horsehunter Creek 
near Macon. They correspond closely with Professor Cope’s description 
cited above. This species appears to have a very wide distribution. It 
was originally described by Professor Cope from the Neuse River, in 
North Carolina. It was next discovered in Southern Illinois by Prof. 
S. A. Forbes, the accomplished superintendent of the Illinois State 
Laboratory of Natural History. I have now the pleasure of announcing 
its occurrence at points much farther south.

This beautiful species appears to be abundant in the Chickasawha 
River. At Enterprise, where I saw a number taken from the water
