Riley — Descriptions of Three New Birds from Canada. 235 



Similar to Passerella iliaca schistacea, but middle of the back mars 

 brown instead of mouse gray ; wings and tail with more red in the brown 

 (near burnt umber). Measurement of type: Wing, 81.5; tail, 7(i; cul- 

 nuMi, ll.o; tarsus, 21; middle toe, 14.5. 



Remarks. — This race is founded on two slightly immature birds from 

 the type loeality; an immature male from Moose Pass, British Columbia; 

 and an immature specimen from Thudade Lake (source of Finlay River), 

 British Columbia. An adult male from Columbia Falls, Montana, Sep- 

 tember lM. L896; an adult male and female, Ft. Klamath, Oregon, April 

 it and 28, 1883; and an adult female, Ft. Crook, California, April 12, 

 L860, all in the collection of the U. S. National Museum, are apparently 

 migrants of this form. They differ from the type in having the upper 

 parts more rusty, but from typical Passerella iliaca schistacea, to which 

 they have been referred, they are quite distinct, having the mouse gray 

 of the upper parts of that race replaced by broccoli brown and burnt 

 umber and the spotting of the under parts prout's brown, not sepia. Ap- 

 parently there is no difference in size.
