This genus is easily distinguished by the peculiar shaped bill 

 which is an elongated spatule, similar to that of a Tody. The 

 wing is rounded, the third, fourth, and fifth primaries longest and 

 equal, the second about equal to the sixth. The tail is rounded 

 and graduated and nearly three-fourths the length of the wing. 

 The tarsus is somewhat long, being nearly two-thirds the length 

 «f the tail, and the hind toe and claw are almost equal in length 

 to that of the middle toe and claw. Coloration : male and female 

 similar.
