FISHES OF THE SANTEE BASIN. 11 



The Santee, Savannah, Altamaha, and Chattahoochee have been 

 examined only in that part of their course which flows over metamor- 

 l)hic rocks. The three western streams have been studied chiefly in the 

 limestone regions. The lithological character of the bed of a stream 

 has a certain influence on its fish-fauna, as will be seen hereafter. Gen- 

 erally limestone streams are richer in si)ecies than those with granitic 

 bottoms. 



The ty[)es of the new species described below are deposited in the 

 United States National Museum at Washington, ancl in the Museum of 

 Butler University, Indianapolis, Indiana. 



I. — SANTEE BASIN. 



Thirty-nine species are ascertained to occur in the headwaters of the 

 Santee River, thirty-three having been obtained by Professor Cope in 

 the Catawba Kiver in North Carolina, and thirty by the present writers 

 in the Saluda and Ennorec in South Carolina. Of these thirty nine 

 species, ten are not as yet known from any other hydrographic 

 basin . These are : Alvordivs erassns, Noihonotus thalassinus, Ceratichthys 

 labrosiis, Ceratichthys zanemus, Godoina pyrrhomelas, Codoma chloristia, 

 Photogenis nii'ens, Alburnops chloroccphalus, Alburnops saludanns, and 

 Myxostoma album. The ai)parent absence of Luxilus coniutus in the 

 Great Pedee, Santee, Savannah, Altamaha, and Chattahoochee Basins is 

 remarkable, as that species is abundant in the tributaries of the Neuse on 

 the east and the Alabama on the west, as in all streams northward to 

 Minnesota and New England. 



The species most abundant as to individuals, in the Saluda at least, 

 is probably Xotropis photogenis. Next to this come Codoma pyirhome- 

 las and Ceratichthys bigitttatus. Of the Catosfomidcc, Myxostoma cervinum 

 seems to be the predominant species j of the Siluridw, Amiurus brun- 

 neus, and of the Centrarchidw, Lepiopomus auritvs. The chief Ibod- 

 fishes at Greenville, S. C, are the "Mud Cats" {Atniitnis brunncus and 

 plafycephalus), the '^Fine-scaled Sucker" [Catostomus commersoni), the 

 Eel {Anguiila vidgar is), the "Spotted Sucker" [Minytremanielanopn), the 

 *• Perch " {Lepiopomus auritus), the "War-mouth Perch" {Chccnobryttus 

 viridis), the "Jack" {Esox reticulaius), and the "Jump Rocks" [Myxo- 

 stoma cervinum).
