I have never collected or seen a bird of this species from Costa 

 Rica, and I have no doubt that it is only an occasional straggler so 

 far north, its occurrence being similar to that of Asturina nitida as 

 recorded by Mr. Bangs. The only authentic record existing which can 

 be used for proof of its ever having been taken in Costa Rica is the single 

 specimen taken by Arce at Bebedero, as recorded by Salvin and God- 

 man (Biologia), from which the description of the species for the 

 Biologia was made. All other records for Urubitinga urubitinga, 

 which can be relied upon, were published prior to the description of 

 U u. ridgwayi by Gurney in 1884, and hence were naturally placed 

 under the only existing species at that time. I do not believe that 

 Costa Rica lies within the true range of the present species, and unless 

 there be absolute proof to the contrary, all specimens of Urubitinga 

 urubitinga from that country should be placed under the following 

 subspecies.
