MUTANDA ORNITHOLOGICA. 

 VII. 



BY HARRY C. OBERHOLSER. 



The names of five species of South American birds, belonging 

 to the families Cotingidae, Tyrannidae, Mimidae and Icteridae, 

 apparently require to be changed. Their names and the reasons 

 for the nomenclatural alterations are given below. 1 



Family COTINGIDAE. 



Attila cinereus (Gmelin). 



The use of Musdcapa cinerea 2 Gmelin for the bird commonly known as 

 Attila cinereus is prevented by Musdcapa cinerea Muller, 3 which is now 

 known as Graucalus cinereus (Muller). The proper title for the species of 

 Cotingidae becomes, therefore, Attila rufus Lafresnaye, 4 proposed as a sub- 

 stitute name for Musdcapa dnerea Gmelin. 



Family TYRANNIDAE. 



Knipolegus comatus (Lichtenstein). 



The name Knipolegus comatus for a South American tyrant flycatcher is 

 now seen to be untenable, for its original combination, Musdcapa comata 

 Lichtenstein, 5 is preoccupied by Musdcapa comata Gmelin. 6 The next 

 available designation is Knipolegus lophotes Boie, 7 and the species should, 

 therefore, stand as Knipolegus lophotes Boie.
