which is probably nearer one-half that size. It is less voracious 

 also than the larger members of its family, and is said to be in 

 no wise detrimental to the Trout, which literally swarm in the 

 same waters. Indeed, its size would render it innocuous to any- 

 thing beyond the small fry, as a well-grown pound Brook Trout 

 would be considerably more than a match for any of these little 

 Pickerel which have come under my observation. In shape 

 and general proportions, the Long Island Pickerel is not dis- 

 similar to the species last described, the head alone excepted, 

 which, allowance being made for the difference of size, and the 

 scaliness of the cheeks and opercula, is in all respects similar to 

 that of the Great Northern Pickerel. 



Its gill-covers do not materially differ from those of the 

 Common Pickerel, except that the lower margin of the suh- 

 operculum is something more oblique, giving the posterior 

 edge of the free margin rather an angular form. 



The branchiostegous rays are four in number; the dorsal 

 fin-rays, twenty-two ; pectoral, sixteen ; ventral, ten ; anal, 

 eighteen ; and caudal, eighteen, seven above, and seven below 

 the great rays. 



Its colour is olive green, darker on the back, and fading into 

 greenish yellow on the sides, irregularly barred with transverse 

 waving bauds of dusky brown, whence its designation of 

 Fasciatus. The fins are brownish green, generally, without 

 spots or bars ; the pectorals and ventrals the palest, and bordered 

 with dingy yellow. 



Before closing this article, I would mention a very remarkable 

 specimen of this fish, which was kindly sent to me by my friend, 

 Mr. William Pennington, of Newark, who perceived that it was
