head prove at first sight its distinctness from P. giiiaiiensis !Sws., which is likewise 

 an inhabitant of British Guiana. Dr. Allen {I.e.) has pointcil ont that a Gniana 

 specimen {modesta) differed from another obtained on the Kio Javarri (nchteri) 

 " in beinu; of a lighter, more yellowish green below, particnilarly on the breast. . . ." 

 Examples from Oyai)oc (C!ayenne), La Union, ('aura (Venezuela), Pederneiras 

 (Rio Madeira), and the upper llio Negro (Marabitanas) are exactly similar to 

 the type of modcsfa, while a series from the Rio Napo, Sarayai^ii ((Jca)'ali, Peru), 

 Iquitos, Rio Javarri (type of sdateri), and (!osnipata (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 sjiecimens are intermediate ; but con- 

 sidered as a whole, the two series may easily lie told iipart. The range of the 

 two races is as follows : —
