HYLA.TOMUS, Baird. 



Dryotomus, Malhehbe, Mem. Ac. Metz. 1849, 329. (Not of Swainson, 1831.) 

 Dryopicus, Bonap. Consp. Zygoi. in Aten. Ital. May, 1854. (Not of Malherbe.) 



Bill a little longer that the head ; considerably depressed, or broader than high at the base. Shaped much as in Campephilus, 

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

 the commissure. Tarsus shorter than any toe, except the inner posterior. Outer posterior toe shortef than the outer anterior, 

 and a little longer than the 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 the tail, reaching to the middle of 

 the exposed surface of tail ; considerably graduated, though pointed ; the fourth and fifth 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 the length of the commissure.

Hab. — North America from Atlantic to Pacific. 



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.
