The typical Ostinopes, which have the base of the lower mandible 

 feathered, are merely larger and stronger forms of C'assicus. They 

 range from Panama to the extreme south of the South-American 

 forests in Brazil and Bolivia. 



Ostinops decamauus, the " Jcipm" of the Brazilians, builds, in 

 colonies, its purse-like nest suspended from the branches of trees 

 over water, and lays two eggs, white, with pale violet-red markings.
