(No. 15, Coll. Salv.) Bill about the length of head; tail longer than the 

 wings, much graduated, the lateral feathers about two-thirds the central. 

 Color of the upper parts light-brown, with a very slight tinge of rufous, which 

 hecomes very decided on top of head. Upper tail coverts obscurely barred ; 

 wings, however, perfectly plain throughout. Chin and throat white, gradually 

 liecoming soiled with fulvous on the median line of body ; the sides and flanks 

 of a shade of brownish, paler than the back. Edge of wing white, inside 

 tinged with fulvous. Crissum ashy-white, barred about equally with black. 

 All the feathers of sides ofhead and neck (including side of lower jaw) 

 white, edged with black, either on both sides or on one only ; the black some- 

 times involving the whole web ou one side. A superciliary white stripe from 

 the bill is obscured by the black and white markings. Upper surface of tail 

 feathers light-brown, like the back, with transverse bars of black, one-half to 

 one-third their interspaces, generally interrupted along the median line, some- 

 times broken up into spots, especially at the ends, the intervals between the 

 bars in places sometimes paler than the ground color. Legs and bill dark 

 plumbeous. 



Total length, 5.70 ; wing, 2.30 ; tail, 2.70 ; exposed portion of 1st primary, 

 .90, of 2d, 1.38, of longest, 5th (measured from exposed base of 1st primary), 

 1.75 ; length of bill from forehead, .68, from nostril, .45, along gape, .83 ; 

 tarsus, .82; middle toe and claw, .68; claw alone, .18; hind toe and claw, 

 .59 ; claw alone, .25. 



This species is closely related, in coloration, to P. rutilus and 

 maculipectus ; especially in the color of the back, becoming more 

 rufous on the head and not on the rump ; the peculiar and very 

 distinct black and white markings of the entire side of the head, the 

 perfectly plain wings, the banded crissum, the much graduated tail, 

 and wings (the 5th or Gth quills longest), etc. It will, however, be 

 very easily distinguished from rutilus, by the absence of Ijlaek spots 

 on the chin and throat, and of the red of the jugulum ; and from 

 maculipectus, by the lack of black spots on the breast ; from both 

 by the presence of bars on the upper tail coverts. The bill has less 

 of the characters of Pheugopedius — being lower, and nearer typical
