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- 

 phic rocks. The three western streams have been studied chiefly in the 

 limestone regions. The litliological 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 's[)ecies than those with granitic 

 bottoms. 



The types of the new species described below are deposited in the 

 United States National Museum at Washington, and in ^le Museum of 

 Lutler 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 Coi)e in 

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

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

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

 basin. These are : Alvordins crassus, Noihonotus thalassinus, Ceratlchthys 

 labrofius, Ccraticlithi/s zauonns, Codonta pyrrlwmdas^ Codoma chloristio, 

 Photoficnis niveus, Alburnops chloroccphahis, Alburnops saludanus, and 

 Myx'Stoma album. The apparent absence of Luxilus cornutus in the 

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

 remarkable, as that si)ecies is abundant in the tributaries of thcNeuse on 

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

 Minnesota and New England. 



The species most a'jundant as to individuals, in the Saluda at least, 

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

 Utsdud CcnitichihysbUjnUatUH. -Jf the Catostomidoi, Myxostvma cervinum 

 seems to be the predominant species; of the Slluridcc, Aminrnn br\in- 

 neus, and of the Centrarchidw, LepiopomiiN auritus. The chief food- 

 fishes at Greenville, S. C, are the " Mud Cats" [Amiurns briinncns and 

 platyecphalus)., the '"Fine-scaled Sucker" (Catostomiis commcrsoni), the 

 Eel {AnguiUa vuhj((ris),i\ni "Spotted Sucker" {Minyfrcina mchoiopti), the 

 *• Perch " {Lepiopoinvs auritus), the ''War-mouth Perch " {Clucnobryttus 

 viridis), the "Jack" {Esox reticulatus), and the " Jumi> Rocks" {Myxo- 

 stoma cervinum).
