1122 MR. C. E. IIELLMAYU OX THE 



is much smaller and lins a considerably shorter, slenderer bill, but 

 is most probably only the northern representative of C. uro- 

 pygialis. The specimens obtained by Lieut. Michler's party 

 on the Falls of the Rio Truando, although referred by 

 Mr. Ridgway* to G. microrhynchus, are more likely to belong- 

 to the present form (cfr. Cassin, Proc. Ac. N. Sci. Philad. 1867, 

 p. 64).

This specimen agrees with others from Western Ecuador, in 

 size and colour. I have not seen typical Mexican birds, which 

 may be different.

C. 0. violea is an excellent form, easily recognizable by the 

 strong violet-purple gloss of the plumage. In typical C. o. 

 oryzivora, from Cayenne, N. Brazil, Venezuela, etc., the gent^'al 

 colour is dull black with bronzy reflection, and very little, if any, 

 violet admixture on pileum and chest. Specimens from Western 

 Ecuador also belong to C. o. violea.
