often been cited, no satisfactory figure o it has yet been published. 

 Having, to my great disappointment, been unable to supply this 

 deficiency, I will not undertake to give a detailed description of it. 

 Those of my readers who desire to know it, will have to consult 

 the works cited in the synonomy, supplying from one what is not 

 furnished by another. In order to complete the history of this fish 

 with success, it will be necessary to give a figure of it with all the 

 exactness of modern science. 



The color varies as much as in the Salmo Fario of Europe. To 

 one of the varieties Rafinesque gave the name of S, nic/rescens. 

 The physiognomy of the young is somewhat different from that of the 

 adult, which has induced Dr. Dekay to make a separate genus of it, 

 which he calls Baione. At that epoch the body is barred vertically 

 with black. There are seven, eight, nine and even ten bands, which 

 grow wider and assume the form of circular spots the more the fish 

 grows. The teeth are all minute and uniform, in these young speci- 

 mens, and have misled Dr. Dekay to view these fishes as the type 

 of a distinct genus. We have procured several individuals of two 

 and three inches, at Black River, with others of from twelve to 

 fifteen inches.

This species is well known under the trivial name of " Tyrant of 

 the lakes," because of its size and voracity, and is much esteemed 

 for food in the countries which it inhabits. As it has been well known 

 for a very long time, I will not repeat what has been said by my pre- 

 decessors, but shall limit myself to citing a few observations which I 

 have been able to make on the living animal. The general color
