1870.] 471 {Cope. 
The color of this species I cannot give, as I have not lately seen it in 
life; in spirits it is uniform silvery, the dorsal fin dusky. 
I know this fish from two specimens which I caught in the Youghi- 
ogheny River, in Western Pennsylvania. 
64. PrycHosToMUS COLLAPSUS, Cope. 
Species nova. 
This very abundant fish is in the form of its lips similar to the last. It 
is stout and short, the head not entering the length (exclus. caudal) quite 
four times. The dorsal line is somewhat elevated to the first ray of the 
dorsal fin, the depth entering the length 3.5 times. The eye is smaller 
than in P. velatus, entering the length of the head 4.75 and 5 times, 
and the interorbital width 1.75 times. Top of head plane; muzzle 
‘moderately prominent, intermediate between P. erythrurus and Pt. conus 
in this respect, being more compressed than in the last. Mouth small, 
little projectile, superior lip pendent. D 15, V. 9. Thoracic region with 
small scales. 
The specimens of this species from most of the North Carolina Rivers 
are rosy on the sides, the larger, light golden ; the inferior fins all orange. 
The specimens from which the above description is taken are small, only 
a foot long, but I have seen several ‘specimens in the Catawba River, of 
three and four pounds in weight. 
It occurs in the Neuse, Yadkin and Catawba Rivers, in North Carolina, 
the Clinch River in Tennessee, and I have a specimen from the Wabash 
River, in Indiana, and three others without locality, but probably from 
the Western States or Great Lakes. In the Yadkin and Catawba Rivers 
it is immensely numerous, and is caught on weir traps in the spring and 
autumn in quantities, and used as food by the inhabitants. It is not as 
good a fish as the P. pappillosus and P. robustus, but it is not at all to be 
rejected. 
There seemed to be a larger number of smaller specimens in the Yadkin 
than the Catawba Rivers at the time of my visit. The specimens from 
the Neuse have the muzzle a little more prominent. Some specimens 
from the Yadkin possess only XIII and XIV D. rays. 
65. PrycHOSTOMUS PIDIENSIS, Cope. 
Species nova. 
A smaller species than either of the prevadiag: of more cylindric and 
less compressed form. The dorsal fin is shorter, containing only XII rays 
Head elongate, about four and a half times in length exclusive of caudal 
fin. Muzzle not conic, but truncate. Scales similar to those of the last spe- 
cies. Length about ten inches. 
Color light brownish yellow, fins light red. 
This fish resembles at first, the Pt. cervinus, both in color, form and 
size. I obtained a few specimens from the traps in the Yadkin River, at 
the plantation of John Kuntz, and did not see it in any other river. 
I took a variety in a tributary stream, characterized by a longitudinal 
black spot at the base of each scale, giving a handsome longitudinal
