Adult male in breeding' plumage (No. 23,575, Coll. Wm. Brewster, 

 Feb. 21, 1887, Camp Huachuca, Arizona) : Above uniform vinaceous- 

 cinnamon, in no contrast to slightly pinker nape, and extending on sides

 101.6 mm. (4.00 in.) ; tail, 719 mm. (2.83 in.) ; tarsus, 20.3 mm. (.80 in.) ; 

 bill from nostril, 9.1 mm. (.36 in.). 



Adult male in autumn plumage (No 23,555, Coll. Wm. Brewster, Sept. 

 28, 1888, Chihuahua, Mexico.) : Above darker and more scorched or 

 rusty than in spring; black areas clouded, and plumage generally softer, 

 otherwise as in spring. 



Adult fe male in breeding plumage (No. 23,58s, Coll. Wm. Brewster, 

 March 2, 18S7, Camp Huachuca, Arizona) : Above reddish cinnamon, 

 streaked continuously from bill to rump-band with darker reddish 

 brown ; no crown patch ; loral stripe faintly indicated with dusky ; jugular 

 patch restricted; otherwise like the male. Wing, 94.7 mm. (3.73 in.); 

 tail, 63.0 mm. (2.48 in.) ; tarsus, 19.8 mm. (.78 in.) ; bill from nostril, 

 S.6 mm. (.34 in.). 



}~ouug, first pltumtge (No. 116,918, U. S. Nat. Mus., Sulphur Spring, 

 Arizona, Aug. 18, 1874). Above pale reddish cinnamon, dotted on head, 

 neck, and back with small buffy spots, tipping feathers that are dark 

 brown subterminally ; wings similar, quills edged with reddish cinnamon ; 

 underparts white, spotted lightly across the throat with dusky upon a 

 buffy band. Tail deep brown, outer feathers tipped and edged with 

 reddish, cinnamon. This bird is very young, the tail not one third grown. 

 As compared with the young of other races, it is almost identical in 

 appearance with chrysolama from Nicasio, California, but the prevailing 

 reddish tints render it easily separable from all the other forms except 

 chrysolcema and rubea of which the series of young is a meagre one. and 

 the constant characters open to some doubt. 



The uniform pale vinaceous-cinnamon above, which tinges the 

 cream)'" white of the lower parts, renders this bird almost unmis- 

 takable. It presents a scorched appearance, the brown more 

 pronounced in autumn.
