The number of species of birds observed and identified 

 with certainty by us was thus 116*; Wallace in 1819 col- 

 lected examples of 28 species. Together this would give the 

 total number of 144 species of River-Capim birds : but there 

 is a reduction to make of 7 species common to both col- 

 lectors, the real total being 137. 



As the Avifauua of the whole Amazonian basin includes, 

 according to our recently executed census, 1156 species f, 

 and as the Avifauna of the State of Para, according to the 

 present state of our knowledge, contains 330 species J — that 

 is, one quarter, more or less, of the whole Amazonian Avi- 

 fauna, — the Capim list, with 137 species, represents between 

 one- third and one-half of the Para ornis, manifestly a 

 considerable fraction, sufficient to allow fairly definite con- 

 clusions regarding the character and composition of the 

 bird-life of this district to be drawn from it. 



Para, August 1902. 



* I have intentionally omitted some species not sufficiently identified, 

 especially among the Trochilids. 



t Our census is based on the 27 volumes of the Brit. Mus. Catalogue. 



| The census, based on the 27 volumes of the Brit. Mus. Catalogue, 

 gives 329 species of Para birds ; the census based on our provisional cata- 

 logue of the collections of the Para Museum (manuscript of 1898 — the 

 new list is not yet quite ready) embraces 326 species. Sclater andSalvin, 

 in their memoir upon Wallace's birds of Lower Amazonia (1867), mention 

 282 species.
