I seem to have wrongly identified Mr. Whitely^s specimens 
with Po 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 relationship 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

or 60J per cent, of the 589 Guiana species.
