Adult male. — Head and neck black, sometimes passing into metallic

I have not seen a specimen from Bahia, and assume that the bhd from that district 

 may be the same as the Lower Amazon form. It certainly can not be either true 

 ramonianus or C. violaceus. But the Bahia bird may be a different form, in which 

 case I propose for the Para bird the name Chrysotrogon ramonianus goeldii. (Type, 

 no. 105,232, coll. U. S. Nat. Mus., Pard, Brazil, March 6, 1881; E. M. Brigham.) 



c With only one specimen of the Lower Amazon form, and none of C. ramonianus 

 ramonianus, I am not able to more satisfactorily characterize the females of these two 

 forms and C. violaceus. 



d More rarely this metallic coloring extends over greater part of the hindneck.
