HYLATOMUS, Baird. 
Dryotomus, Malherbe, Mem. Ac. Metz, 1849, 322. (Not of Swainson, 1831.) 
Dryopicxis, Bonap. Consp. Zygod. 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 shorter 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 , hut 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.

the wing,) axillaries, and under wing coverts, and concealed bases of all the quills, with chin and beneath the head, white,

18 inches; wing, 9j.

Hub. —North America from Atlantic to Pacific. 
Specimens of this species from tbe 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.
