This example, apparently an adult, does not altogether 

 agree with the specimens in the British Museum obtained 

 by Prof. Graham Kerr on the Bio Pilcomayo, and by 

 Mr. Foster at Sapucay, respectively. It is nearer to the 

 Bio Pilcomayo specimen, except that the top of the head 

 and the primaries are much paler.

This specimen is identical with JNIr. Foster's and other 

 specimens from Paraguay. It still retains in the left 

 wing one inner secondai'y of the immature plumage, but is 

 otherwise quite adult.
