MITCHILL ON THE FISHES OF NEW-YORK. 435 



1. Common Salmon. (Salmo solar.) Of a silvery gray colour, with 

 spots, and in the male, incurvated jaws. 



Has been taken, since the discovery, a few times in the Hudson. 

 But here he is a straggling fish, and not in his regular home. There is 

 no steady migration of salmon to this river. Though pains has been 

 taken to cherish the breed, salmon has never frequented the Hudson in 

 any other manner than as a stray. The supply to the New-York mar- 

 ket usually came from Connecticut river ; but since dams and impedi- 

 ments have kept the salmon away from their customary places of resort 

 in that stream, they have been brought from the Kennebec, covered in 

 ice. Their season is the middle of May, or beginning of June. 



2. Smelt. (Salmo eperlanus.) Bluish silvery salmon, with transpa- 

 rent head, and seventeen rays in the anal fin. 



This fish is occasionally brought to the New-York market ; but he 

 is not a steady visiter. I have eaten him in fine style at Newark, 

 whither he was brought from the Passaic river. 



3. Common Trout. (Salmo fontinalis.) With yellow and red spots 

 on both sides of the lateral line, concave tail, and sides of the belly 

 orange red. 



Back mottled pale and brown. Sides dark brown, with yellow and 

 red spots ; the yellow larger than the red, and surrounding them. The 

 latter appear like scarlet dots. Lateral line straight. The yellow 

 spots and red dots both above and below that line. Sides of the belly 

 orange red. Lowest part of the abdomen whitish, with a smutty tinge. 

 First rays of the pectoral, ventral, and anal fins white, the second black, 

 the rest purplish red. Dorsal fin mottled of yellowish and black. 



Tail rather concave, but not amounting to a fork ; and of a reddish, 

 purple, with blackish spots above and below. 



Eyes large and pale. Mouth wide. Teeth sharp. Tongue distinct. 

 Skin scajeless,
