This bird is practically identical with others from Eastern Ecuador and 

 Northern Peru. Compared with a series of true T. i. iynobilis 8cl. from Bogotd 

 collections, it fully bears out the distinctive characters as given /.(?. See also ray 

 remarks in Nov. Zool. xiii. 1900, p. 6. 



T. i. (hhilis ranges from Eastern Ecuador through Northern and Central Peru 

 to N.W. Brazil (Rio Puri'is and Rio Madeira). Occasionally it is also met with in 

 Bogota collections (cf. Nov. Zool. xiii. 1906, p. 5).

 bill blackish, base of lower mandible yellowish." — Wing Hi) ; tail 92 ; bill 20 mm. 



This bird agrees perfectly witli a series from iS.E. Brazil and Corrientes, 

 Argentine. It difters from the specimen of T. i. debilis obtained at S. Isabel by 

 Mr. Hoffmanns by its longer wings and tail, blackish loral spot, pnre white chin 

 (without any brown striations), much broader and more blackish brown stripes on 

 the throat, ranch paler, bufty brownish instead of plain ashy breast and sides, clear 

 ochraceons bnff (not greyish brown) under wing-coverts, and by having well-defined, 

 bright ochraceons edges to the inner webs of the remiges, altogether absent in 

 T. i. debilis. The bill, too, is not uniform blackish, the basal half of the lower 

 mandible being clear yellowish brown ; there is also a spot of pale brown on the 

 culmen near the tip. 



This is, so far as I know, the first record of T. ftmanrochalinu.i from any 

 Amazonian locality, though its occurrence on the Rio Madeira is not to be 

 wondered at, for it was well known as an inhabitant of Northern Bolivia on the 

 headwaters of tliat river. I expect, moreover, that T. brunneus Lawr. * will also 

 prove to belong to T. amaurocliulinH.i. 



It is highly interesting to meet with T. aimurochalinus and T. i. debilis in the 

 same locality. TheVe can be no longer any doubt about their specific ilistinctness.
