Agrees with our series from the ('aura River, Venezneln. The chestnut of 

 the pileum and wings seems to lie a little more intense, but this is certainly an 

 individual character. 



61. Automolus ochrolaemus turdinus (Pelz.). 



[Anabates ochrolaemus Tschudi, Arch. Noting. 10. i. p. 295 (1844— "Waldregion von Peru" ; cf. 



Faun. Peruan. Ares p. 240).] 

 Anabates turdinus Pelzeln, Sitzungsber. Ahad. Wicn xxxiv. p. 110 (1859— "Brasilia" : viz. Barra do 



Bio Negro and Borba ; cf. Zur Urnith. Bras. i. 1867. p. 41). 



No. 1447. ? (?) ad., Borba, 5. xii. 00. " Iris dark brown, feet pale bluish 

 grey, bill black, below grey."— Wing 88 ; tail 78 ; bill 22 mm. 



Differs very markedly from an adult male collected by Cherrie near Mnn- 

 dnapo, Orinoco River, by its paler, less ochreous underparts, and much duller, 

 brownish olive (instead of bright rnfesceut brown) back. 



Some time ago, however, I carefully compared Natterer's typical specimens 

 from Mauaos and Borba, kindly lent by Dr. Lorenz, with a fair series from 

 British Guiana, the Orinoco River, and Bogota collections, mostly in fount 

 Berlepsch's Museum, and was unable to find any constant differences between 

 the examples from these widely separated localities. 



A. o. turdinus differs from the more western A. o. ochrolaemus (Tsch.), of 

 which I examined the type belonging to the Neuchatel Museum, and another 

 specimen from the Huallaga in Count Berlepsch's collection, merely by having 

 the throat and malar region buff, almost whitish on the chin instead of deep 

 ochraceons. 



62. Philydor pyrrhodes (Gab.). 



Cf. supra, p. 1G. 



Philydor pyrrhodes Pelzeln, Zur Ornith. Bras. i. 18G7. p. 40 (Salto do Girao). 



No. 1071. cT ad., Humaytha, 11. viii. 06. "Iris brown, feet yellow, bill 

 greyish black."— Wing 93, tail 67 ; bill 18 mm. 



Lower surface deep tawny ochraceous, as in an adult male from Munduapo, 

 Orinoco River. The birds with paler, more ochraceous underparts are undoubtedly 

 immature. 



63. Xenops genibarbis genibarbis 111. 



Cf. supra, p. 54. 



Nos. 993, 1028, 1072, 1177. ? ad., ? ? jr., Humaytha, 20, 31. vii., 11, 28. 

 viii. 06. "Iris brown, feet brown or grey, bill dark grey." — Wing 031, 04, 61, 

 62 ; tail 49, 49, 46, 49; bill 14—15 mm. 



No. 1446. ? imm., Borba, 5. xii. 00. " Iris brown, feet bluish grey, bill 

 blackish grey." — Wing 03 ; tail 48 mm. ; bill damaged. 



This series fully bears out what I said I.e., the Madeira specimens being in 

 every respect similar to the topotypical birds from the Lower Amazons. 



64. Dendrornis guttata guttatoides (Lafr.). 

 Cf. supra, p. 59. 



Nos. 1022, 1007, 1002. 6 ad., c? imm., ¥ ad., Humaytha, 27, 30. vii., 7. viii. 06. 

 "Iris brown, bill yellowish grey."— Wing 124, 124, 115; tail 102, 104,103; 

 bill 40J, 42, 39 mm.
