stronger than in adnlt birds of '/'. c. cora>/a, and the dusky barring of the upper 

 tail-coverts npon wliioh Dr. 8harpe and Count Rerlepseh laid ranch stress is not a 

 constant feature cither. The light-colonred tail-bauds are dingy greyish or ashy, 

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

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

 numerous white longitudinal streaks on the ear-covcrts. 



Material. — 1 $ , 1 S iinni. from Sarayai-n, Bartlctt coll., in British (Ji/pe) and 

 Triug Museums ; 1 S ad. Ynrimaguas, (J. Gnrlep[) coll., Mus. H. v. Berlepsch. 



Two males from Sarayaon . . . Wing 69,01 ; tail 01,51 ; bill 18, 17J mm. 

 One male from Ynrimaguas . . . AVing 62 ; tail 5'i ; bill ITi ram. 



Oiservatioii.t. — The type (from Sarayacn) and the Ynrimaguas specimen have 

 the foreueck and chest pale greyish white, clouded with brownish (like T. c. cornj/a), 

 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 rnfons- 

 browu in the Ynrimaguas bird, but strongly barred with blackish in the two 

 Sarayacn skins.

Adult. — Differs from T. coraija amazonieus by lacking the white streaks on 

 sides of head, and by having the tail-bauds 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 reirion. 



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

 Schunke in February 19U9, in the Zoological Museum of Munich. 

 S ad. Wing 65 ; tail 50 ; bill 15 mra. 

 ? imm. Wing 04 ; tail 57| : bill 10 inra. 



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

 ceding race. Tiie back and outer margins of the reraiges show exactly the 

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

 passing into a purer bufty along the middle <if the abdomen ; the sides are clear 

 fulvous brown. From 7'. corai/a herbcrti 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.
