THE DUSKY WOLF. 

 Lupus nubilus, Wibd. 



PLATE III. 



Observed in latitudes to the north of the Canadas, 

 presents the counterpart to the Russsian black 

 variety of the mountains, and approximates also 

 more to dogs. It is of a greyish black partially 

 tinged with brown. 



These species of the two continents may there- 

 fore be considered as identical at present, forming 

 three ancient and permanent races. 



Although the wolves of America, like the foxes 

 of the same part of the world, are varied in their 

 colours, we think Baron Cuvier mistaken when he 

 thought the older authors, who minutely described 

 the Mexican, are not to be credited, for the species 

 sent by Mr Humboldt is evidently not different, 

 and is undoubtedly the same as the caygotte of the 

 natives and coyotl of Fernandez.
