 greater wing-coverts tipped with a bar of black (the middle or some 

 of the posterior lesser coverts sometimes also black-tipped or mar-

a Of the two adult females examined one has this patch yellow, as in the male, the 

 other orange-ochraceous. 1 am therefore unable to determine which is the more 

 usual color. 



b Five specimens, three of them in immature plumage. 



The series examined is much too small to enable me to determine whether there 

 are any constant geographic differences in coloration or measurements. 



c Of two young males, one (from Segovia River, southern Honduras) has the sub- 

 axillary patch large and bright lemon yellow, the other (from Loma del Leon, Panama) 

 has it orange-ochraceous with a very slight tinge or admixture of yellow near outer 

 edge; the three young females examined, on the other hand, all have this space 

 orange-ochraceous, though one of them (from Panama) shows a slight admixture of 

 yellow. 



d These feathers 1 take to be remnants of the first plumage.
