APPENDIX. 



[No. VL 



The ventrals are about one-fourth part nearer to the head than to the tail. The adi- 

 pose fin is moderately large, and opposite to the posterior third of the anal fin. The 

 anal fin is large and long, and terminates about one-third of its own length from 

 the insertion of the caudal fin. The caudal fin is widely emarginated with obtuse 

 rounded lobes.

 Length, exclusive of caudal fin, 30 inches. 



This fish differs from Seba's in size, the latter being only 5f inches long, and in 

 wanting serratures on the first ray of the dorsal fin, and teeth on the palate. Both, 

 however, are described from dried specimens, and they agree in so many circum- 

 stances, that it has been judged best to consider Seba's as a young mathemegh. We 

 had neglected to take a description from a recent fish. The silurus catus of Catesby 

 differs in having its first dorsal fin of a conical form, placed in the middle of its body. 



The nathemegh is found sparingly in the lakes that flow into the Saskatchawan, 

 and more abundantly in the lakes and rivers to the southward. It is much prized as 

 a rich food.

The burbot is found in every river and lake in the country, and attains the length 

 of 30 inches, or more. It spawns in February. It preys upon every kind of fish that 

 it can swallow, and in the spring its stomach is generally crammed with cray-fish, 

 often to such a degree as to distort the shape of the body. 



The burbot is so little esteemed as food as to be eaten only in cases of necessity. 

 Very good bread, however, may be made of the roe, and the livers are always prized. 

 Dogs will scarcely ever eat this fish.

 enough forward.)
