 This species is readily distinguishable from the Pic. pnncipalis by 

 its much larger size ; by the length of ils occipital crest, the pendent 

 silky feathers of which measure nearly 4 inches ; by the absence of 

 the white stripe which ornaments the neck of that bird; and by the 

 bristles which cover its nostrils being black, whercas those of the Pic. 

 principalis are white.
