Rill a liltlo loiigpr lliat the head ; considt'rably depressed, or bronJor than liigh at tlie base. Shaped much as In Campephilus, 

 except shorter, and without the brislly feathers directed forwards at the base of the lower jaw. Gonys about half the length of 

 the coniniissuro. Tarsus shorter than any too, except the inner posterior. Outer posterior too shorter than the outer anterior, 

 and a little longoc than Uio inner anterior. Inner posterior very short; not half the outer anterior; about half the inner 

 anterior one. 



Tail long, graduated ; the longer feathers much incurved at the tip. Wing longer than tho tail, reaching to the middle of 

 the exposed surface of tail ; considerably graduated, though pointed ; the fourth and tiftli quills longest. 



Color uniform black, with white patches on the side of the head. Head with pointed crest 



This genus is very similar to Campephilus, but differs chiefly in the less development of the 

 outer hind toe, which is about exactly intermediate between the outer and inner anterior, the 

 outer largest ; instead of being longest, and having the outer anterior intermediate between it 

 and the inner. The bill is shorter ; the gonys fully half tlic length of the commissure.

Specimens of this species from the southern States are considerably smaller than Pennsylvania 

 and Oregon ones. The wing of a male (4925) from the St. John's river, Florida, is nearly an 

 inch shorter than the northern average. There is no appreciable difference in western and 



eastern ones.
