From the Neuse River, N. Ca. 
In this species, as in all the fork-tailed Amiuri here described, the lower 
lobe of the caudal fin is wider than the superior. The young of these 
species, at least in and A. lynz, 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. IcTALURUS C@ERULESCENS, 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 Amiuri of the East, 
for though the flesh is whiter, it is drier. 
SALMO, Linn. 
81. SaumMo FonTrINaALis, Mitch. 
This species is found in the rapid streams in which the tributaries of 
the Tennessee and Catawba 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, where the size was much inferior to that of trout from 
similar localities in Pennsylvania. 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 cvast or in the rivers of North Carolina, I introduce it here 
for the purpose 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
