occupied by this bird is given review. It may be noted also that the 

 display of males of cerritus, as I saw it in January and February 1958, 

 was similar to that of typical vitellinus. 



Following is a summary of the subspecies of vitellinus based on this 

 examination, with the races arranged in geographic sequence from 

 west to east.
