DENDROCOLAPTIDAE THE WOODHEWERS. 



Twenty-six species and subspecies were included in the Berlepsch 

 and Hartert paper, twenty-three of which number were collected by 

 the writer on the Orinoco proper and three received by the Tring 

 Museum from points on the Caura River.

 ber of species and of individuals was found in the heavily forested 

 regions above the cataracts of Atures and Maipures.
