In these the beak is thicker and more gibbous 

 than in Quails ; the neck is slender, clothed with 

 elongated, somewhat curled feathers, which gives 

 a peculiar air : the nostrils are placed in a groove, 

 situated on each side of the upper mandible : the 

 space round the eye is naked : the tarsi are short, 

 and the tail small, but longer than in the Quails. 

 They perch on trees, and are all natives of Ame- 

 rica.
