I have not seen a specimen from Bahia, and assume that the bird 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 Par4 bird the name Chrysotrogon ramonianus goeldii. (Type, 
no. 105,232, coll. U. S. Nat. Mus., Pard, Brazil, March 6, 1881; E. M. Brigham.) 
¢ 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. 
4 More rarely this metallic coloring extends over greater part of the hindneck.
