head prove at first sight its distinctness from P. guianensis Sws., which is likewise 
an inhabitant of British Guiana. Dr. Allen (/.c.) has pointed ont that a Guiana 
specimen (modesta) differed from another obtained on the Rio Javarri (selater?) 
“in being of a lighter, more yellowish green below, particularly on the breast... .” 
Examples from Oyapoc (Cayenne), La Union, Caura (Venezuela), Pederneiras 
(Rio Madeira), and the upper Rio Negro (Marabitanas) are exactly similar to 
the type of modesta, while a series from the Rio Napo, Sarayacu (Ucayali, Peru), 
Iquitos, Rio Javarri (type of sclater’), and Cosnipata (S.E. Pern) differ in darker 
and greener general coloration, particularly of the under parts, and darker blue 
rump of the males. Some of the Iquitos specimens are intermediate; but con- 
sidered as a whole, the two series may easily be told apart. The range of the 
two races is as follows :—
