a Demerara? (Cashmore) 1843. b (Dewgard) 1849. c 

 Argent (1851). 



a is probably the 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 

 ' Nomenclator.'
