 culmen. The wing is rounded, the second, third, fourth, and fifth 

 primaries longest, the first about equal in length to the seventh. 

 The tail is slightly emarginate and about two-thirds the length of 

 the wing. The tarsus is about two-thirds the lenoth of the tail 

 and the hind toe and claw about equal to the middle toe and claw. 

 Coloration: male and female dilferent.
