This genus is distinguished chiefly by the short wings and long- 

 tail. The bill is pointed and somewhat compressed, the depth and 

 ■width at the base are eq.ual and about two-thirds the length o£ the 

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

 sixth primaries longest and subequal, the second about equal in 

 length to the eighth, and the first about four-tenths shorter than the 

 second. The tail is rounded at the tip, the middle feathers being 

 nearly one-fourth longer than the outermost. The tarsus is about 

 twice as long as the exposed culmen and about one-fourth longer 

 than the middle toe and claw. Coloration : male and female 

 similar.
