It is doubtful whether this species and it« allies should be allowed 

 full specific value, for in the series of specimens lent to me by 

 Messrs. Salvin and Godman there are certain differences which seem 

 to indicate that they are races of one and the same bird. Thus in 

 Guatemalan examples the lower parts are deep rufous fawn-colour 

 over the whole of the abdomen up to the lower breast, while the 

 checks and ear-coverts are ashy whitish. In Panama skins {T. 

 (lalhraithi) the sides of the face are purer white, and the flanks and 

 under tail-coverts are very pale fawn-buff. In the race called 



* Should this species ultimately prove distinct, it may bear Natterer's MS. 

 name of ruJivetiMs, as follows : —

It is scarcely likely that the Brazilian bird will be the same as that from 

 Panama.
