THE SISKAWITZ. 137 



THE SISKAWITZ. 



Salmo Siscowet. 



THIS species has a dentition very similar to the 

 Salmo Amethystus, but not quite so robust. The 

 upper and lower maxillaiies and intermaxillaries, 

 and each of the palatines, have a row of teeth. The 

 vomer one and the tongue two rows, beside the 

 acute teeth. The tail is less furcate, and the dorsal 

 fin is larger than in the Mackinaw Salmon. The 

 flesh is rich and of fine flavor, but almost too fat. 



The fin rays are: D. 12, P. 14, A. 12, 14, V. 9, 

 C. 30. 



This fish is shorter and stouter, and not so dis- 

 tinctly spotted as the Mackinaw Salmon ; it is alto- 

 gether less handsome, but has similar habits, and 

 bites readily at the trolling spoon. It was first de- 

 scribed by Professor Agassiz, not many years ago, 

 during his tour of Lake Superior, but has always 

 been distinguished by the Indians and Voyageurs, and 

 known among them under its distinctive appellation. 



The Siskawitz inhabits the upper portion of Lake 

 Superior, and never descends towards the outlet, and 

 is taken in the .neighborhood of Isle Royale in abun- 

 dance. It is said also to be found in some of our 

 other lakes, but is very rare.
