All the specimens have the top of the head warm brown like the back, not 
slate-grey. Cf. Berlepsch & Hellmayr, Journ. f. Ornith. 1905. p. 17. 
According to Mr. Hoffmanns, this bird frequents thickets in the primeval forest 
and keeps near the ground.

“Tris greyish brown or brown, feet brown, bill black, lower mandible yellowish 
grey.” 
The adult male has the pileam and nape smoky grey ; the back russet-brown, 
the mantle paler and more olive ; the innermost flanks and the under tail-coverts 
washed with rufescent brown. In immature birds the upper parts are of a deeper, 
more chestnut brown, the pileam and nape tinged with brownish; the sides of 
breast and abdomen are more strongly suffused with rusty brown, and the feathers 
of the throat show more or less distinct dusky edges. Moreover, the young male 
(No. 214) has the romp and upper tail-coverts conspicuously barred or streaked 
with black, and the edges to the upper wing-coverts of a brighter, more cinna- 
momeous tinge. 
All of the specimens have the foreneck extensively sulphur-yellow with a 
number of dull orange-red spots. The rectrices are blackish, edged with dull 
rufous brown edges along the basal half of the outer web. The upper mandible 
is black, the lower one, with the exception of the tomiae, horny white. 
L. t. thoracicus appears to inhabit both banks of the Rio Madeira. Natterer 
met with it at Salto do Girao, on the left side, as well as at Borba, on the right 
bank, where Mr. Hoffmanns also obtained his examples. No other specimens are 
on record. <A nearly allied form, LZ. thoracicus erithacus Scl.,* however, occurs in 
Eastern Ecuador, where it was discovered by the late C. Buckley. It merely 
differs by its rather stronger bill, and by lacking the sulphnur-yellow tinge on 
the foreneck, the latter being spotted with dull orange-red on a pure white 
ground.
