236 NEW-YORK FAUNA. 



mottlings. First dorsal pale yellowish, with horizontal interrupted bars of dark green. Pec- 

 torals pointed ; the first ray light yellow ; the second blackish, and the remainder orange. 

 Ventrals and anal with their first rays entirely white, as are the tips of the second and third 

 rays. The bodies of the second and third, and the tip of the fourth, black, which causes 

 them to appear blackish on their edges, and broadly bordered with white ; the remaining rays 

 reddish. Caudal reddish, with obscure parallel dark bands, which are more distinct towards 

 the tips of the lobes. Irides white. 



Length, 8-0. Depth, 1'3. 



Fin rays, D. 13.0; P. 12; V. 8 ; A. 10; C. 19 |. 



The specimen from which the above description was taken, was a female. It is about the 

 average size of the smaller kind of brook trout. I have never seen any exceeding fourteen 

 inches in length, but I am credibly informed of one taken on Long island, which measured 

 twenty inches in length, and weighed four and a half pounds. Those from running streams 

 are better flavored than the pond trout ; and those taken from streams to which tlie salt water 

 has access, are preferred to either. The latter have brighter colors externally, and their flesh 

 has more of the salmon color. 



The Brook Trout is a northern species, being found in almost all the clear running streams 

 and ponds tliroughout this and the northern States. I am unable to state with precision its 

 southerly range. It occurs in the head waters of the Delaware, Susquehannah and Allegany 

 rivers, but never descends into the Ohio. According to Dr. Kirtland, it is found only in two 

 small streams in the State of Ohio, viz. a small creek in Ashtabula county, and a branch of 

 Chagrin river, Geauga county, bordering upon Lake Erie. I have no information of its being 

 found north of the forty-seventh or south of the fortieth parallel of latitude.
