4 Strange to say, all specimens I have seen (4 apparently adults) from the Rio 

 Branco region, N. Brazil, agree perfectly with birds from Rio Aurare and Maracay, 

 northwestern Venezuela (in yellow on face, being absent or confined to trace around 

 the eye, etc.). 



b Eupsittula pertinax margaritensis subsp. nov. : Type from Margarita Island 

 (off Venezuela). Adult male, No. 39151, Field Museum of Natural History. Col- 

 lected by J. H. Ferry, March I, 1909. Similar to E. p. chrysophrys (SWAINSON) 

 from Guiana in having the pronounced yellow markings on face and other characters, 

 but differs in having the throat and cheeks paler and the forehead more distinctly 

 and more extensively whitish. It approaches very closely to E. p. chrysophrys, but in 

 15 out of 19 specimens from Margarita Island these differences appear to be constant.
