Eleven specimens, both sexes, adult and immature, Vicinity of 

 Paramaribo, and Javaweg, February, March, April, and June. 



Birds from Paraguay, Uruguay, and southern Brazil are certainly 

 different from the Guiana bird in being larger, and also browner and 

 paler above. From T. n. excellens (Sclater) of Central America both 

 South American forms differ in having much smaller bills. 



The larger southern bird should be known as 



87a. Tapera naevia chochi Vieillot. 

 Type-locality. — Paraguay. 



The tail-measurements are not very reliable, on account of the 

 worn condition of some and fresh condition of others. 



88. Crotophaga major Gmelin. 



Seven specimens, both sexes. Vicinity of Paramaribo, January, 

 March, April, and December. 



1 Penard Coll.
