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 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 species 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 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 River in Xorth Carolina, and thirty by the present writers 

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

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

 basin. These are : Alvordius crassus, Noihonotus thalassinus, Ceraticlithys 

 labroftiiSj Ceratichtlujs zancmus, Codowa pyrrhomelas, Codoma chloristia^ 

 Photogcnis nireus, Alburnops chlorocephalus, Alburnops saludamts, and 

 Myxostoma album. The apparent absence of Luxilus cornutus in the 

 Givat 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 pliotogenis. Xext to this come Codoma pyrrlwme- 

 las and Ccraiiclitliys biyitttatus. Of the Catostomidcc, Myxostoma ceri'inum 

 seems to be .the predominant species; of the Siluridcc, Amiurus brun- 

 neus, and of the Centrarcliidce, Lepiopomiis auritus. The chief food- 

 fishes at Greenville, S. C., are the "Mud Cats" (Amiurus brunneus and 

 platyccplialus], the '-Fine-scaled Sucker" (Catostomns commersoni), the 

 Eel (Anguilla vulgar is), the "Spotted Sucker' 7 (Minytremamelanops^tbQ 

 * Perch " (Lepiopomus auritus}, the "\Var-mouth Perch" (Clicenobryttus 

 riridis), the "Jack" (Esox retlculatus), and the "Jump Rocks" (Myxo- 

 stoma cervinum).
