GENUS GADITS. 83 



naturalist, who had travelled in North America, published 

 some years ago, in Europe, an account of some of the 

 fishes of the United States. This work I have earnestly- 

 desired to sec, but my friends here have not been enabled 

 to procure it for me. It is possible that some of the 

 above described fishes, as well as others which I at pre- 

 sent consider as nondescripts^ may have been noticed by 

 the German naturalist. 



Description of two new species of the genus Gadus. By 

 Mr. Le Sueur. Read August 26, 1817. 



In the fresh water lakes and rivers of North America, 

 there have been found two species of the Cod family^,

 lughby, p. 175, mem. 2, cap, % tab. L. ed. 1686; and 

 likewise the G. Danicus^ of which iViuller gave the first 

 description. This resemblance consists in the lengthen-

 but the following specific characters indicate an impor-

 jsingle cirrus; ground colour of the body reddish, marbled 

 with brown, with roundish white spocs scattered through-

 vertical line with the angle of the mouth; nostrils double;
