Carriker : List of the Birds of Costa Rica. 667 



Acad. Nat. Sci. Philadelphia: Bebedero, Sept. it, 1893, ? (Under- 

 wood). 



In the Birds of North and Middle America, Mr. Ridgway states that 

 he is of the opinion that Pachyrhamphus ornatus Cherrie is merely the 

 female of P. albo-griseus Sclater, which opinion I likewise share, for 

 the same reason which he gives, namely, that P. albo-griseus has been 

 taken in western Nicaragua, Panama, and Colombia, but as yet has 

 never been taken in Costa Rica, unless the female Pachyrhamphus 

 described by Mr. Cherrie as ornaius is in reality the female of albo- 

 griseus. I examined a female Pachyrhamphus in the collection of the 

 Philadelphia Academy, taken at Bebedero by Underwood, and it seems 

 to me very probable that it is the female of the bird under discussion, 

 albo-griseus. It hardly seems possible that there should be another 

 species of Pachyrhamphus found within the range of albo-griseus, 

 which is so closely related to it as P. ornatus must be to have the female 

 resemble the female of that species so closely. After carefully 

 considering these facts I have placed Pachyrhamphus ornatus Cherrie 

 under the synonymy of Pachyrhamphus albo-griseus albo-griseus, and 

 added that species to the list of authentic species of Costa Rican birds.
