Family APHREDODERIDtE. 

 Genus APHREDODERUS, Le Sueur. 



22. Aphredodenis sayanus (Gilliams) DcKay. 



Aphrcdoderns saijanuf!, DeKay, Fauna N. Y. Fishes, 35. 



Apliododerm isolepsis (Nejls.) Jordan, Bull. UL Lab. Nat. Hist. No. 2, 48. 



Aphrodcdirus cookianus, Jordan, Pioc. Acad. Nat. Sci. Phlla. 1877, 60. 



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. 



Family CYPRINODONTID^. 

 Genus ZYGONECTES, Agassiz. 



23. Zygonectes notatus (Raf.) Jordan. (No. 27,444.) 



Zygoneotes notatus, Jordan, Bull. U. S. Nat. Mus. No. 9, 47. 



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 3 

 inches long to the caudal, or a total of 3J 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. 



24. Zygonectes tnelanops (Cope) Jordan. (No. 27,427.) 



Haplochilus melavops, CoPE, Proc. Araer. Phil. Soc. 1870, 457. 

 Zygonectes melanops, Jordan, Bull. 111. Lab. Nat. Hist. No. 2, 52. 



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 

 Laboiatorj^ of Natural History. I have now the j)leasure of announcing 

 its occurrence at points much farther south. 



Family HYODONTIDJE. 

 Genus HYODON, Le Sueur. 



25. Hyodon selenops, Jordan & Bean. (No. 27,455.) 



Uyodon selenops, Jordan, Bull. U. S. Nat. Mus. No. 10, 67. 



This beautiful species appears to be abundant in the Chickasawha 

 River. At Enterj)rise, where I saw a number taken from the water
