1870.]', '*'-^ [Cope. 



The color of this species I cannot give, as I have not seen it in life ; in 

 spirits it is nniform silvery, the dorsal fin dusky. 



I know this fish from two specimens which I caught in the Youghi- 

 ogheny River, in Western Pennsylvania. 



64. Ptychostomus 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 entei'ing 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 the 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. conns 

 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 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. Ptychostomus pidiensis, Cope. 



Species nova. 



A. smaller species than either of the preceding, of more cylindric and 

 less compressed form. Tiie dorsal fin is shorter, containing only XII rays. 

 Head elongate, about four and a half times in length exclusive of cauda^ 

 fin. Muzzle not conic, but truncate. Scales similar to those of the last spe- 

 cies. Leng-th about ten inches. 



Color light brownish yellow, fins light red. 



This fish resembles at first, the Pt, cermnits, 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
