The CouAs. Vaill. 



Differ from the cuckows proper, only in having ele- 

 vated tarsi. They build in the clefts of trees, and 

 do not deposit their eggs in the nests of other birds. 

 This at least is true of such species whose habits are 

 known. 



M. Vieillot has made his genus Coccyzus of this 

 division, the Macropus of Spix.
