Ihis species has a very wide range in South America ; but though 

 Its casual appearance in Cuba has been recorded, it has never yet been 

 met with in Central America. Commencing from the valley of the 

 Magdalena It spreads over the whole continent, including the island 

 ot Innidad, as far as the vicinity of Buenos Ayres. In Parao-uay 

 Azara saw it in large flocks of as many as two hundred individuals 

 and niore. He notes its cry as " bi-bi-bi;' which is uttered as it flies 

 at all hours of the night. The members of a flock fly in a strai<^ht line 

 or crescent. ' ° 



Genus 2. Sarcidiornis. Type. 



Sarcidiornis, Eyton, Mon. Anat. p. 20 (1838) . . S. melanonota. 



This genus appears to be truly Tropicopolitan, and is represented 

 by two or three species or closely allied forms in India, Africa, and 

 America.

We are unable to give a description of this species, as no authentic 

 houth-American examples are at present accessible to us. It is 

 therefore not possible for us to give independent testimony as to the 

 identity or distinctness of the birds found in South America, Africa, 

 and India ; but we have good reason to believe that the South- 

 American form is really separable.
