synonyms. Mr. Sharpe is certainly at fault in his identifi¬ 
cation of the Strix ferox of Vieillot, the description of which 
distinctly states that the crown is spotted with white*, whereas 
in every plumage of the present bird it is narrowly streaked. 
The tail is also stated to be spotted with white. This form is 
perhaps to be referred to G. pumilum; but this is uncertain. 
Although seventy specimens have been examinedf by me 
(nearly twice the number inspected by Mr. Sharpe), I cannot 
recognize the local differences upon which Mr. Sharpe bases 
his G. phalcenoides and G. ridgwayi, and consider them un¬ 
tenable even as climatic or geographical races, and. conse¬ 
quently include these names among the synonyms of a species 
far more variable individually than climatically.

Mr. Sharpe remarks that he considers this species to be 
“ confined to Brazil, and not to range, as Mr. Ridgway sup¬ 
poses, into Central America.Consequently the two spe¬ 
cimens from Guatemala in Mr. Ridgway^s paper are G. gri¬ 
seiceps and not G. pumilum 33 (pp. 40, 41). This statement 
prompted a re-examination of my Guatemalan specimen, which 
proves to be an extreme example of G. pumilum , as distin¬ 
guished from “ G. griseiceps 33 and corresponds exactly with the 
figure on plate ii. fig. 1, except that it has even more chestnut 
lower parts and back. This specimen was procured by exchange 
from the Boston Society of Natural History, in whose col¬ 
lection were several similar ones, obtained in Guatemala by 
Van Patten. The immature example in Mr. Lawrence^s col¬ 
lection, mentioned on page 98 of my monograph, is exactly
