Description. 



Adult (50947, Brazil; Sr. Don Fred. Albuquerque). 



Upper surface dark umber, inclining to clove-brown, becoming 

 more rufescent on rump and upper tail-coverts; head above with 

 longitudinal lines of yellowish white ; scapulars and wing coverts 

 with a very few roundish spots of white ; spots on outer webs of 

 primaries very obscure, not approaching white. Tail brownish-black, 

 crossed with seven series of transverse ovate spots of white, these 

 touching neither the shaft nor edge of the feathers. Sides of the 

 breast and stripes on the sides and crissum somewkat lighter and 

 less fuliginous brown. Wing, 3.70; tail, 2.60; tarsus, .70 ; middle 

 toe, .65. Wing formula, 3, 4, 5-Q = 2; 1st shortest. 



This specimen unquestionably represents the true infuscatum of 

 Temminck. The present bird and the gnoma Wagl. of Middle Amer- 

 ica seem to be merely two races of the same species, and distinguish- 

 able only by the darker brown and greater restriction of white in the 

 present bird. In both there is exactly the same size and proportion, 

 and the same pattern and tints of coloration, distinguishing them 

 from all the other species.
