coverts, and axillaries brown : total length 4-6 inches, wing 4-15, tail 2-0. 

 Female similar. 



Hob. Guiana, Brazil, and Northern Argentina. 



This Swallow is common near Mendoza, according to Prof. Bur- 

 meister. White obtained it in May 1881 at Santo Tome, Corrientes, 

 and in 1882 at Cosquin near Cordova. At Cosquin the first individual 

 was seen on July 20th, but towards the end of August large numbers 

 were observed, mostly skimming over the river.

Fam. IX. TANAGEID^E, OR TANAGERS. 



The brilliant family of Tanagers, one of the most characteristic groups 

 of the American avifauna, contains altogether nearly 400 species, of 

 which the greater number are restricted to the forest-clad districts of 

 Central and South America between the tropics. South of the Tropic 

 of Cancer the number of species met with falls off very considerably, so 

 that in the Argentine Republic only fourteen members of the family 

 have as yet been recognized. This number will, however, be probably 

 increased when the less-known wooded districts of northern and eastern 

 Argentina have been more fully explored. 



The fourteen species of Argentine Tanagers belong to ten different 

 genera, mostly of wide distribution. But to this rule one genus (Ste- 

 phanophorus) is an exception, being only found in Southern Brazil, 

 Paraguay, Uruguay, and Northern La Plata.
