Carnegie Museum : El Pozo de Terraba, June 18, 1907, c? (Carriker). 



I have followed Mr. Bangs in placing this bird in a separate genus 

 (Rhinoptynx Kaup), for after having seen the bird in life and care- 

 fully examined it afterwards, I do not believe it to be either a Bubo or 

 Asio. 



The specimen taken by Underwood at San Jose is the first record 

 of the species north of Panama and it is remarkable that another 

 should have been found so soon afterwards in a different region. 



169. Bubo virginianus mesembrinus (Oberholser). 



Asio magellanicus mesembrinus Oberholser, Proc. U. S. Nat. Mus., XXVII,
