there are differences in tlie females which seem to indicate a constant dis- 

 tinctness. Those males which I obtained in spring have the lesser coverts 

 entirely yellow, thus agreeing with the most essential character of plumage, 



distinguishing this from A. r/nhcrnafor, which has them tipped with hlack. 

 Eggs from Santa liai'bara, measure 1.00 X 0.73 iuch, and are bluish-white 

 with blackish streaks near the large end.
