FISHES OF THE SAVANNAH BASIN. 31 



is marked by pretty regular Hues of dark olive-green spots along the 

 series of scales. The lower fins are usually more or less red, and the 

 black, yellow, and white coloration of the caudal fin, so conspicuous in 

 young si)ecimeus of the Xortheru form — ia the Western States, at least — 

 is not noticeable in the Southern variety. 



This species is abundant in the tributaries of the Savannah, where it 

 is known as the " Trout ". 



Genus XENOTIS Jordan. 

 3. Xenotis sanguinolentus {Agassiz) Jordan. 



Jordan (1877), Aun. Lye. Nat. Hist. 318. 



A single si)ecimen of this beautiful fish is in the National Museum 

 from Augusta, Ga. It is identical with ray specimens from the Etowah, 

 mentioned in the paper above cited, but it is possibly not the si)ecies 

 to which Agassiz gave the name of sanguinolcntus. The species of the 

 genus Xenotis are extremely difficult either to define or to recognize. 



CYPRINODONTID^. 



Genus ZYGONECTES Agassiz. 

 4. ZYGONECTES NOTTii Agassiz. 

 A " Zggonecfps guttatus " is recorded by Professor Agassiz from the 

 Savannah near Augusta. Professor Putnam informs me, from the ex- 

 amination of the type-specimens, that the si)ecies is identical with Z. 

 nottii Ag. 



SALMONID^E. 

 Genus SALVELINUS Bichardson. 



5. SALVELINUS FONTINALIS (Ji<7c/i.) Gill & Jov. 



The common Brook Trout is very abundant in the clear tributaries of 

 the Chatuga and Toxaway Kivers, at the foot of the Blue Kidge. This 

 is very near the southern limit of the species, although it is said to occur 

 in certain tributaries of the Upper Chattahoochee, farther west. 



CYPEINIDJ]. 



Genus LUXILUS Bafinesque. 

 6. LuxiLUB coccoGENis {Copc) Jordan. 

 This beautiful species is common in the Tugaloo. The numerous 

 specimens were all palo, and showed only traces of the distinctive red 

 markings.
