stronger than in adult birds of T. c. coraya^ and the dusky barring of the upper 

 tail-coverts upon which Dr. Sharpe and Count Berlepsch laid much stress is not a 

 constant feature either. The light-coloured tail-bands are dingy greyish or ashy, 

 only the basal ones slightly tinged with fulvous, exactly as in T. c. coraya, with 

 which T. c. amazonicus also agrees in having a very distinct superciliary stripe and 

 numerous white longitudinal streaks on the ear-coverts. 



Material. 1 c?, 1 <? imm. from Sarayac.u, Bartlett coll., in British (type) and 

 Tring Museums ; 1 cT ad. Yurimaguas, G. Garlepp coll., Mus. H. v. Berlepsch. 



Two males from Sarayacu . . . Wing 69,61 ; tail 61,51 ; bill 18,17| mm. 

 One male from Yurimaguas . . . Wing 62 ; tail 56 ; bill 17 mm. 



Observations. The type (from Sarayacu) and the Yurimaguas specimen have 

 the foreneck and chest pale greyish white, clouded with brownish (like T. c. coraya), 

 while the second (immature) male from the Ucayali shows a distinct buff wash all 

 over the middle of the belly. The upper tail-coverts are nearly uniform rufous- 

 brown in the Yurimaguas bird, but strongly barred with blackish in the two 

 Sarayagu skins.

Adult. Differs from T. coraya amazonicus by lacking the white streaks on 

 sides of head, and by having the tail-bands bright cinnamon-brown (instead of dull 

 ashy or brownish grey). The white superciliary stripe is barely indicated by a 

 few minute, obsolete lines above the auricular region. 



Material. 1 cT ad., 1 ? imm. from Chanchamayo, obtained by Mr. C. 0. 

 Schunke in February 1909, in the Zoological Museum of Munich. 

 <? ad. Wing 65 ; tail 56 ; bill 15 mm. 

 ? imm. Wing 64 ; tail 57 J ; bill 16 mm. 



Observations. The two specimens agree in general coloration with the pre- 

 ceding race. The back and outer margins of the remiges show exactly the 

 same light (cinnamon) rufous-brown tinge ; the foreneck is pale greyish buff, 

 passing into a purer buffy along the middle of the abdomen ; the sides are clear 

 fulvous brown. From T. coraya herberti they may be distinguished by the much 

 paler rufous upper parts and flanks, as also by the greater reduction of the white 

 markings on the " mask," the auriculars being quite uniform blackish and the 

 superciliary line barely visible.
