The eyes are small; situated more on the 

 upper part of the head than usual, and are be- 

 hind the loose edge of the flap belonging to the 

 bill. The eyelids are concealed in the hair, and,

 of the mouth, there is a pouch, as in the mon-

 and the same in breadth. In the female it con-

 each pouch.

 Each foot has five toes, united by the web,
