Mus. S. & G. 



We cannot now tell whether the specimens from David and Mos- 

 quitia ought to be referred to this northern form, or to its southern 

 representative A. cayennensis, which certainly occurs as far north as 

 Panama. 



We are likewise uncertain what Prof. Schlegel's A. ypecaha from 

 the " Isle de St. Thomas" may be, unless it is referable to the pre- 

 sent bird. The true " Ypacaha " of Azara is undoubtedly the same 

 species as that which Schlegel refers to as A. gigas.
