I seem to have wrongly identified Mr. Wlntely^s specimens 

 with P. nigrigenys. They should be referred to P. gularis. 

 The true P. nigrigenys is a Venezuelan bird, and has a black 

 patch behind the eye and a wholly red throat. 



SUMMARY. 



Before comparing the birds of Guiana with those of the 

 chief portions of America bearing some relationshij) to 

 them, it seems necessary to eliminate the migratory species 

 and also the sea-birds from our consideration. Thus we 

 have : — 



Total number of species in the Guiana list . 625 



Less migratory species , 29 



sea-birds 7 



— 36 



Remainder for comparison . . 589 



These 589 species are distributed as follows : — 



1. Amazons valley, including that of the Rio Negro. 

 Total number of Guiana species found in 



the Amazons valley 377 



Less migratory species 17 



sea-birds 4 



— 21 



356 

 or 6O4 per cent, of the 589 Guiana species.
