Description. — Head dark neutral gray, this color extending over 

 the nape and sides of the head; pileum with two blackish lateral 

 stripes of black, not sharply defined, inclosing a large coronal spot 

 of lemon chrome (some of the feathers with slight darker tips) ; 

 indistinct supraloral streak paler gray; upper parts, and wings and 

 tail externally, bright olive citrine; throat and breast grayish (pallid 

 neutral gray medially) ; rest of under parts lemon yellow, duller on 

 the crissum, the sides and flanks washed with pyrite yellow; under 

 wing-coverts dull pyrite yellow ; "' iris brOAA n ; bill blackish ; feet pale 

 brownish yellow" (Carriker). 



Measurements. — Male (seven specimens) : Wing, 67-70 (average, 

 G9.5) ; tail, 58-G3 (CO) ; bill, 10-12 (11) ; tarsus, 21-22 (21.5). Female 

 (eight specimens) : Wing, 62-67 (65) ; tail, 57-61 (60) ; bill, 10.5-11 

 (10.8); tarsus, 20.5-22 (21). 



Range. — Subtropical Zone, Eastern Andes of Colombia. 



Remarks. — Until more recent years this species appears to have been 

 known only from "• Bogota '' skins, when reported by Doctor Chap- 

 man from the definite locality Buena Vista, on the eastern slope of the 

 Eastern Andes. Mr. Carriker met with it in the region of Ocana, 

 farther north, on both slopes of the rp.nge, and secured a good series 

 of si^ecimens, which have been made the basis for some critical re- 

 marks by the writer. The species c]e.arly belongs to the same group 

 as B. coronatus, but differs decidedly from that species in its less 

 sharply defined lateral crown-stripes, yellow instead of orange ^^ufous 

 vertical stripe, and greater extent of gray on the breast. It bears a 

 remarkable superficial resemblance to Oj)orornis Philadelphia and 

 O. agilis in general appearance. 



Three individuals in the collection of the Carnegie Museum which 

 T take to be younger birds (August 12 and 15) differ from the adults 

 in having the head more or less washed with the color of the back, the 

 lateral crown-stripes barely indicated, and the coronal spot duller and 

 reduced in size. In some adults the coronal spot inclines more to light 

 cadmium.
