These specimens agree in every respect with others, in the 

 British Museum series, from various parts of South America. 

 I have, therefore, followed Dr. Ihering in placing X. aryo- 

 bronchus Bertoni as a synonym of the present species. 



[This peculiar little bird is rare with us. All these 

 S. American Creepers are so much alike in their habits that 

 little can be said about any one in particular. — W. F.~\

I agree with Dr. Ihering and C. W. Richmond in uniting 

 Geowcia orryctera of Bertoni with the present species, as the 

 specimens recorded above are identical in every respect witli 

 others in the National Collection from E. Brazil. 



[One of our very rare forest birds. Its habits are very 

 similar to those of the Thrushes. It lives entirely upon the 

 ground in the deepest and gloomiest parts of the forest. It 

 is not by any means shy, and if not startled will feed close 

 up to the observer. — W. F.~\
