a is probably tbe type of D. melanotis , Strickl. Both a and b (a 
female) are made up in the form of Cayenne skins, c is probably 
from Bogota. 
As the Cayenne and New Granadian forms of this bird seem 
inseparable as species, the name they should bear is D. angelica , and 
not D. melanotis , that adopted by Mr Sclater and myself in our 
1 Nomenclator.’
