insular form, is in the present specimens easily separated from 

 the latter species owing to its smaller size and by having 

 the postnasal feathers tinted with påle orange red. The under 

 parts are more ochraceous and tinged with a slight shade of 

 red, one of the birds having the målar region påle orange red. 

 Iris as noted on labels reddish brown.

Bångs remarks about the birds (1 (^, 1 $) of this species 

 collected by Mr. Brown on his first trip to the Pearl Islands, 

 that they compare in color with South American specimens 

 but that the wings are a little short for true oleaginea and a 

 little long for parca. On his second trip Mr. Brown again 

 obtained two specimens (c^, $), and Thayer and Bångs ref er 

 them to P. o. oleaginea, stating that like the first pair they 

 compare very favourably with South American examples and 

 are slightly larger and a little paler in color than P. o. parca 

 of Panama mainland.

 specimens from the isthmus and San Miguel, but placed all 

 together with the specimens from the Santa Marta district 

 of Colombia, they are easily distinguished from samples from 

 other parts of South America. 



As I have no material for comparison, I cannot decide
