of the Genera Tetrao and Ortyz. 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.
