paler, but quite uniform, rufous, relieved by few or no marking s of any 

 kind ; the rest of the lower parts are white, the feathers with i distinct 

 mesial streaks of dusky brownish and faint and ragged cro^^ bars of 

 pale rufous. These specimens resemble the extreme rufous phase of 

 ^''hrasilianus^\ as described above, except that there are no distinct 

 blackish streaks on the back, where also the feathers are devoid of the 

 basal fulvous spots, while the bars on the lower surface are much less 

 distinct and regular. 



Two other specimens of this phase in the collection of Messes. Salvia 

 and Godman are quite different. One, from Coban, Vera Paz, is a 

 young bird, with remnants of the immature plumage. The new dress 

 however, largely prevails. In this example, the whole dorsal region is 

 varied by an exceedingly faint, yet obvious spotting of a paler rufous, 

 and narrow blackish shaft-streaks, and the lower parts are much more 

 distinctly and regularly barred, the bars being, moreover, of a consid- 

 erably darker shade. It thus approximates quite closely to the rufous 

 specimen of " hrasilianus^^ above referred to. The other specimen is from 

 Las Salinas, Vera Paz (" March, O. S. 2349"), and is still more different. 

 The upper parts are so dark as to be almost chestnut, while the back 

 is distinctly spotted with black. The breast is nearly uniform dark
