At least two species must be removed from this genus. One of 

 these is Muscicapara gaimardi D'Orbigny and Lafresnaye/' which, 

 having pycnaspidean tarsi, must be placed (according to our present 

 definition of Oligomyodean groups) in the Cotingidse;'' the other is 

 Elainea rufice/ps Pelzeln, '^ a true Tyrannine, but certainly not a mem- 

 ber of the present genus, from which it differs in relatively much 

 larger and broader bill, much stouter feet, shorter and more rounded 

 wing, relatively much shorter tail, differently shaped nostrils, and 

 dissimilar coloration, and not being referable to any other genus, 

 should constitute one by itself.

Having seen authentic specimens of E. elegaris only, I merely follow Doctor Sclater 

 in considering it the same as Muscicapara gaiynardi D'Orbigny; but as Doctor Sclater 

 erroneously referred another form to the same species, E. macilvainii Lawrence, which 

 is at least subspecifically distinct, he may have erred in this case also.
