with a longitudinal line black anteriorly and red poste- 

 riorly. 



It is found in the brooks of the Alleghany moun- 

 tains falling into the Alleghany and Monongahela. 

 It has the manner of the small Brook-trouts, and is 

 called Mountain-trout, Creek-trout, &c. It is easily 

 caught with the hook, baited with earth-worms, and 

 they may be easily enticed by rubbing the bait and 

 hook with asafcetida like many other fishes. They 

 afford a very good food. Length about 8 inches. 

 Head olivaceous with violet shades. Iris brown. 

 Dorsal fin rufous with brown lines parallel with the 

 back. Pectoral fins oval, not reaching the base of 

 the dorsal nor abdominal fins, redish below, whitish 

 above, with a brown line. Abdominal fins with nine 

 rays and similar to the pectoral fins in colour, scaly 

 appendage very small. Tail with brown shades. 

 Adipose fin acute. Diameter of the body one sixth 

 of the total length. I have seen some individuals 

 (they may be the female or a variety) who were of a 

 paler colour, with fewer and smaller scarlet dots; 

 they had the yellowish spots more crowded, the fins 

 darker and the tail pale. 



[II. 235] 35th Species. Black Trout. Salmo

A very rare species, seen only once, near the Lau- 

 rel hills; it is said to be found also in the Yoho- 

 gheny, a branch of the Monongahela. Length six 

 inches, diameter one fifth of total length. Iris black 

 and gilt. Slightly pale under the body.
