39. DENDRORNIS*. rp^pg 



Deudroruis, Eyton, Contr. Orn. 1852, p. i';3 D. susurrans. 



Dendrornis is cue of the most difficult groups of this perplexing 

 subfamily, and I do not delude myself with the idea that I have 

 been successful in reducing the various forms and their complicated 

 synonymy into satisfactory order. I am able, however, to recognize 

 sixteen species, which are spread over the forests of Central and 

 South America from Mexico to Southern ISrazil. The Dendromithes 

 are Deiulrocolapthue of moderate size, with the bill straight and 

 rather elongated, but the culmen and commissure slightly incured.
