a fair series from Bahia and Pani, tin- breast and abdomen are rnneli brighter, 

 ochraceous, paler in the middle. The barring of the (inter tail-leathers varies iii 

 individuals from the same locality, the dusky bars being Bometimes restricted 

 to the inner webs, sometimes extended over both webs. The type from the 

 Rio Jnrua which I have examined is an immature bird, and agrees in size with 

 No. 988. 



It may be added that the adult cf, collected by Natterer near Burba, on the 

 right bank of the lower Rio Madeira, belongs to T. g. genibarbis. It is perfectly 

 similar to examples from Para, which differ from Bahia skins solely by their 

 rather thicker and larger bills. 



6. Leucolepia modulator rufogularis (Des Mars). 



Cf. supra, p. 41. 



No. 1222. cf ad., Humaytha, 12. ix. 06. "Iris greyish brown, feet dark grey, 

 bill black."— Wing 72 ; tail 41 ; bill 19 mm. 



Differs from our Teffe' specimen by having the belly, particularly in the middle, 

 less rufescent, though much more so than in Bolivian skins [/,. m. modulator 

 (D'Orb.)]. The ferruginous colour below is confined to the throat and foreneck, as 

 in the types of L. modulator, while in the Peruvian and Teffe birds it extends 

 over the middle of the chest. 



7. Grauatellus pelzelni pelzelni Scl. 



Cf. supra, p. 5. 



No. 1346. cf junior, Borba, 17. xi. 06. "Iris brown, feet grey, bill blackish 



grey-" 



No. 1379. ? ad., Borba, 22. xi. 06. " Iris brown, feet grey, bill greyish black." 

 These specimens agree perfectly with others from Santarem and the (.'aura 

 valley, Venezuela.

 Wing 69 ; tail 54; bill 19 mm. 



Though not quite adult, these specimens undoubtedly belong to C.g. gujanensis, 

 the chest, flanks, and crissum being distinctly washed with cinereous, and the 

 middle of the belly white without any buff tinge. They agree perfectly with skins 

 from Cayenne, Surinam, and Para.
