serrate. Radii D 1. 6; A. 24; V. 8. Maxillary barbel to near end of hu- 

 meral process; latter very rugose to near extremity. Outer mental barbel 

 to branchiostegal margin. Br. rays ix. 



Color above blackisb, sides silvery leaden blue; below, including margin 

 of upper lip and outer margin of maxillary barbels, pure white. Fins 

 edged with dusky. Length of specimens 8.3 inches. 



From the Neuse River, N. Ca. 



In this species, as in all the fork-tailed Amiuri here described, the lower 

 lobe of the caudal tin is wider than the superior. The young of these 

 species, at least in and A. lynx, are much more silvery than the adult, as 

 is the case with some of the Ictaluri. 



In concluding my observations on this genus, I may add that I took A, 

 cupreus in the Clinch River, in Tennessee. 



ICTALURUS, Raf. 

 Gill emend. 



80. ICTALUKUS CtERCLESCENS, Raf. 



This species abounds in the French Broad and other tributaries of the 

 Tennessee, as it does in those of the Ohio. It is everywhere much used 

 as food, though in my estimation inferior to the large Aniiu)-i of the East, 

 for though the flesh is v,duter, it is drier. 



SALMO, Linn. 



81. SaLMO FOKTISALIS, Mitch. 

 This species is found in the rapid streams in which the tributaries of 

 the Tennessee and Catav.'ba Rivers head, in the highest tracts of the Alle- 

 gheny Mountain Region. I only took them in one of the heads of the 

 French Broad, Avhere the size was much inferior to that of trout from 

 similar localities in Pennsylvc^nia. The experience of other fishermen in 

 this respect was similar to my own. According to Dr. Hardy, a natural- 

 ist long resident in Asheville, well known to the old generation of stu- 

 dents South and North, this fish occurs in the headwaters of the Chatta- 

 hoochee, on the south slope of the Alleghenies, in Georgia. This is the 

 first authentic instance of its occurrence in any water flowing directly into 

 the Gulf of Mexico, with which I have met. From the habits of the spe- 

 cies it is hardly to be looked for in any other of the Gulf streams eastward 

 of the Mississippi. According to Dr. Peck, of Mossy Creek, Tennessee, 

 it is not found in the Cumberland Mountains. I did not find it there in 

 the heads of the Cumberland or Clinch. 



OSMERUS, Artedi. 

 Although I am not informed as to the occurrence of any species of this 

 genus on the coast or in the rivers of North Carolina, I introduce it here 

 for the puri^ose of illustrating some species which have been placed in my 

 hands by my friend. Dr. Chas. C. Abbott, of Trenton, N. J. These were 

 procured and forwarded to him at his request, by Chas. G. Atkins, the 

 efficient Commissioner of Fisheries of the State of Maine, whose authority
