This Tanager bears so great a resemblance to the previous species, 

 that I have not thought it necessary to give a separate figure of it ; 

 and indeed I have some doubts of the validity of its claim to specific 

 distinction from Calliste cay ana. The most apparent differences are 

 its slightly larger dimensions and greater briUiancy of colouring, par- 

 ticularly in the amount of grey-blue upon the throat, which has led 

 Prince Bonaparte to apply to it the term eyanolaima. This word I 

 have altered, in accordance with the rules given in the Report 

 adopted by the British Association on the subject of Zoological No- 

 menclature, into cyanolcema. My collection contains several exam- 

 ples of this bird, received from M. Parzudaki of Paris, who likewise, 

 I believe, supplied the specimens whence Prince Bonaparte's original 

 description was taken. They are all labelled "Rio Negro;" but I 

 do not know upon what part of the territory called by that name they 

 were collected, nor have I met with specimens elsewhere.
