 flanks, lower abdomen, and under tail-coverts, the feathers narrowly and 

 indistinctly barred with dusky where the two colors merge together; 

 wings bright burnt-umber brown ; rest of upper parts (except head and 

 neck) duller, more bister brown, the rectrices passing into dull black ter- 

 minally ; inner webs of remiges dull cinnamon, the terminal third (ap- 

 proximately) dusky, under wing-coverts dusky grayish brown, becoming 

 nearly black along edge of the wing. Naked orbital space apparently 

 yellowish in life; bill, legs, and feet blackish, the first inclining to horn- 

 color terminally. Length (skin) G; wing 3.15, tail 2.15 ,exposed culmen, 

 .65, bill from nostril .42, tarsus 1.10, middle toe .68.

13, Dendrornis fraterculus, sp. uov. 



Sp. char. — Similar to I), stmirrans (Jard.), from Tobago, but much 

 smaller (wing 3.75, tail 3.25), the bill disproportionately so (exposed 

 culmen 1.15); plumage rather darker, the chin and throat decided buff 

 instead of dull bufify whitish, spots on breast, etc., deeper buffy, rather 

 larger, and more distinctly margined with dusky, and shafts of rectrices 

 bright chestnut, like the webs, instead of blackish. 



Hahitat. — Lower Amazon (Diamantina). 



Adult male (Diamantina, Lower Amazon,* June 10, 1887 ; C. B. Eiker) : 

 Pileum and hind-neck sooty black, each feather marked with a median 

 guttate streak of buft', the ground-color of the hind-neck much mixed 

 with bister-brownish, the black being confined to the margins of the 

 buff streaks; back, scapulars, and wing-coverts light bister-brown, the 

 upper portion of the first marked with guttate streaks of buff, these 

 much larger than those on hind-neck, and distinctly margined with 

 black ; secondaries, rump, upper tail-coverts, and tail uniform chestnut, 

 the last with shafts clear chestnut; primaries chestnut-brownish, their 

 inner webs mainly clear chestnut except terminally, where dull dusky 

 brownish, this color gradually increasing in extent toward exterior quill, 

 which has the chestnut restricted to a very limited portion toward 

 base. Sides of head buff, the feathers narrowly margined with dusky ; 

 throat similarly marked, but dusky margins becoming almost obsolete 

 on upper portion, quite so on chin ; sides of neck similar to hind-neck, 

 but buff" markings broader; chest and upper breast with still broader 

 central guttate spots of buff margined with dusky, the edges of the 

 feathers, however, brownisli ; lower breast and upper belly similarly 

 spotted, but the spots less distinct on account of the lighter color
