Bab. Guiana, Brazil, Paraguay, Bolivia, and Eastern Peru. 



This widely diffused bird varies considerably in difiereut localities ; 

 but, so far as I can tell from available materials, the differences are 

 hardly sufficient for siiecific separation. The bird described above 

 is the typical Guianan form. The Brazilian form (E. violaceicollis. 

 Cab.) is larger (whole length 3-5 inches, wing 2-2, tail 1-3) and 

 has more violet-purplish sheen on the fore neck. The Bolivian 

 form (upon the female of which I believe E. serrirostris, d'Orb. & 

 Lafr., to have been established) is again rather larger (whole length 

 3"7 inches, wing 2-4, tail 1-5), but scarcely otherwise separable
