Until I had actually seen the typical example of this fine 

 Ant-Thrush, which has been most liberally intrusted to my 

 examination by the authorities of the Smithsonian Institu- 

 tion, I was, I confess, rather unwilling to believe in its dis- 

 tinctness from its near ally, G. squamigera, which actually 

 traverses Ecuador, and extends into Peru and Bolivia. But 

 I was quickly convinced at the first sight of the bird. 



The only known example of this species was obtained in 

 Ecuador by Mr. John Akhurst. It bears the number 35101 

 in the Smithsonian Catalogue. It is not known more exactly 

 where the specimen was procured.

The larger size and lighter colour below induced me to 

 separate the Mexican from the Guatemalan form of this 

 species ; but I rather doubt whether the separation will be 

 ultimately maintainable, as there is considerable variation in 

 G. guatemalensis when a large series is examined.
