of the Genera Tetrao and Ortyx. 143 



the birds from this last locality appear larger, the colours more 

 distinct, and the white on the extremity of the tail much broader. 

 I cannot for the present attempt to separate them from the spe- 

 cies found on the Rocky Mountains, as my specimens from the 

 coast are all destroyed ; but probably they will be found on 

 comparison distinct. 



Three or four years ago, Mr. Sabine received specimens of 

 this through the Hudson's Bay Company, probably taken in the 

 mountains near the sources of the river Athabasca. The name 

 was given by Mr. Sabine, in honour of Dr. Richardson, whose 

 varied scientific acquirements have eminently contributed to the 

 advancement of natural history. 



The present species is nearly allied to T. obscura of Say, one 

 of the birds observed during Long's Expedition to the Rocky 

 Mountains.
