Wing, 202; tail, 144; tarsus, 37.5 mm. 



Average measurements of four males from Quito and Mt. Chim- 

 borazo: Wing, 196 to 205, average 200; tail, 140 to 144, average 141; 

 width of tail band, 16 to 20, average 18 mm. Measurements of three 

 females: Wing, 194 to 208; tail, 143 to 148 mm. 



Comparative differences. The male of this large, deeply colored 

 race may be distinguished at a glance from all other known American 

 forms (except C. s. ochracea and C. s. intermedia) by its deep ochraceous 

 cinnamon and usually nearly immaculate under parts; its large size; 

 long tail; and noticeably white blotches or spots on the outer webs of 

 several (including the second) of the outer primaries. From C. s. 

 ochracea it may be distinguished by its much narrower tail band, which 

 in ochracea averages about 29 mm. ; larger size; and the large white spots 

 on the outer web of the second (outer) primary and several of the 

 others. From C. s. intermedia it may be separated by its much longer 

 tail; average larger size; somewhat narrower tail band; buffy tinge on 

 outer under wing coverts; and the larger and more numerous white 

 spots on the second, third and fourth outer primaries. From the type 

 specimen of C. s. cequatorialis it differs in its much more deeply colored 

 under parts; absence of numerous, large, rounded black spots; much 

 narrower tail band; somewhat larger size, and the presence of several 

 large white spots on the outer webs of several of the outer primaries. 

 The female averages larger in size, the breast is rather more tawny, and 

 the buffy spots on the second and third (outer) primaries are larger 

 and more numerous than in allied races. 



Specimens examined: Ecuador Mt. Chimborazo, 3 o" ; Quito, 

 i d", i 9; Riobamba, id"; "Ecuador," id"; Ambato, 2 9; Chuncha, 

 i 9 ; Cumbaga, i 9 . 



Remarks: Two males have the inner web of the outer rectrix 

 rufous, with the usual subterminal band of black and the tip white. 

 Two others have the greater portion of the web rufous, but have two 

 black bands on the terminal part, the space between the bands being 

 white. None of them show any rufous on the crown, and in four out 

 of the five males the tips of the rectrices are more or less mixed with 

 rufous. None of the females show any rufous on the crown. The 

 specimen from Riobamba, which I have provisionally referred to this 

 race, is not typical. It is smaller (wing, 185; tail, 136); has less white 

 marking on the outer web of the third and fourth outer primaries and 

 some white mixed with the rufous and a second black band on the 

 terminal part of the outer rectrix. Another specimen from Huigra, 

 Chimborazo (alt. about 5000 ft.), is apparently an intergrade, being 

 smaller (wing, 187; tail, 130); the under parts paler; tail band 24; and
