V °i889 n '] PROCEEDINGS OF THE NATIONAL MUSEUM. 7 



Aii adult from Orizaba in the collection of the Museum of Compara- 

 tive Zoology, Cambridge, Massachusetts (No. 31837), is like the one de- 

 scribed above, but is slightly more olivaceous beneath, the upper belly 

 somewhat tinged with tawny, and the outer surface of the remiges 

 (except tertials) more strongly washed with brown. The bill is also 

 somewhat paler, being tinged with horn-whitish on terminal portion of 

 the culmeu,aud on the gouys. Length (skin), 13.00; wing, 5.55; tail, 

 5.30 ; culmen, 2.35 ; depth of bill at angle, .40 ; tarsus, 1.32 ; middle toe, 

 1.12. 



I am less surprised that this very distinct species should have been 

 at first referred to X. albicollis than that it could afterwards have been 

 considered the same as the Guatemalan X. emigrans.
