Thi.s intere.sting \ariety of the Canada "rouse, if it be not a distinct 

 species, replaces the other form in tlie Eocky Mountains of the United 

 States, hut does not seem to extend iinich northward, as all specimens re- 

 ceived at the Smitlisonian Institution, from the JVIackenzie Paver region, 

 and Alaska, including Sitka, are true T. Ciniadcn.'iis. The differences consist 

 mainly in a rather longer, broader, and nuu'e truncated tail, which is pure 

 black to tlie ends, instead of l>cing tipped with In-own ish-orange. The up- 

 per tail coverts also are sharjily ended with white. The female has the tail 

 tipped with whitish, instead of orange-brown. 



The species is abundant in the Eocky and Bitter Eoot IMountains, and 

 extends to the Cascade Eange. It lives among the spruce and pine 

 vegetation, princiimlly in swami)y tracts, feeding on leaves an<l l)uds of 

 the conifertc. The eggs are light chocolate-brown, spotted with tlarker, 

 mucli like those of the Canada grouse. (Baird.)
