266 Riker and Chapman, Birds at Santarem, Brazil. IJu'y 



different from galbraithi (Lawr.), by some authors synonymized with 

 leucotis.—F. M. C] 



7. Thryophilus taenioptera Ridgw. 



Thryophilus tcenioptera Ridgw., Proc. U. S. Nat. Mus., X, 1SS7, p. 51S. 



A male taken June 29, 1SS7, on the 'mountain' in a dense forest amongst 

 the tangled roots of climbing vines. There were several together, and 

 when disturbed by the report of my gun, they darted off with a sudden 

 outcry of shrill calls. 



[This bird bears a close relationship to a specimen from Guiana, which 

 I take to be Thryophilus albipcctus (Cab.), a species which is generally 

 synonymized with leucotis (Lafr.). Apparently we have then at Santarem 

 two cpiite different birds, but both, by different lines of divergence, bear- 

 ing relationships to the same species. — F. M. C] 



8. Thryothorus herberti Rikcr. 



Th ryot horns herberti Riker MS., Ridgw., Proc. U. S. Nat. Mus., X, 

 18S7, p. 516. 



Two males taken June 13 and 29, 18S7, on the 'mountain' in palm 

 thickets. 



[Having no material with which to compare this species, I can add 

 nothing to the remarks contained in the original description. — F. M. C] 



9. Anthus rufus (Gm.). — Two specimens taken on the meadow, June 

 and July, 1887. 



10. Vireo chivi agilis (Licht.). — Common in lowlands. A busy little 

 bird, having a song very much resembling that of our V. olivaceus. 



11. Cyclorhis guianensis (Gm.). — Two specimens, male and female, 

 taken July 9 and 13, 18S7, from the treetops in the lowlands. 



[For remarks on this species, see Allen, Bull. Am. Mus. Nat. Hist., II, 

 iSS 9 , P . 133— F. M. C]

13. Tachycineta albiventris (Bodd.). — Common about water, June to 

 August, 1887.

 taken June 1, 1SS7. 



[15. Dacnis plumbea (Lath.). — A male taken by Smith January 21, 

 18S9. Not before recorded from the Amazon, although it is necessarily

17. Ccereba chloropyga (Cab.). — A female taken July 15, 1SS4.

 and two females taken August 4, 18S4, and June 29, 1887.

 lows": Wing, 2.21; tail, 1.15; culmen, .32 in. Two females average: 

 Wing, 2.15; tail, nS; culmen, .32 in. — F. M. C]
