(light olive), and nnderparts much less fulvous (pale grayish buff tinged 

 with grayish olive on chest, sides, flanks and under tail-coverts) ; wing, bill, 

 tarsus, and middle toe longer, tail shorter. 



Aditll male (two spedinens).— Wing, !)lM)5 (!):].5) ; tail, 71-75.5 (7:}.2) ; 

 exposed culmen, 17.5 ; tarsus, 23-24.5 (23.7) ; middle toe, 15.5.

 exposed culmen, 17.5-19 (18.2); tarsus, 24-25 (24.5); middle toe, 14-14.5 

 (14.2).* 



This form is very distinct from any other of its Central American con- 

 genei-s, and requires comparison only with 7*. rubra of Venezuela and 

 Trinidad, from which it is easily distinguished by the characters mentioned 

 above. In addition to the specimens in the collection of the U. S. National 

 Museum I have examined ten males and seven females in the collection of 

 the National Museum of Costa Rica. 



Named for Don Anastasio .Alfaro, Director of the National Museum of 

 Costa Rica, to whom I am indebted for many courtesies during my visit to 

 that country, not the least of which is his genial and helpful companion- 

 ship on several collecting trips.
