HYLA.TOMUS, Baird. 



Dryotomns, Malherbe, Mem. Ac. Metz, 1849, 322. (Not of Svvainson, 1831.) 

 Dnjopicus, 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 Campephilua, 

 except shorter, and without the brisily 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, 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.

 color of body, wings, and tail dull greenish black. A narrow white streak from just above the eye to the occiput ; a wider one 

 from the nostril feathers (inclusive) under the eye and along the side of the head and neck ; sides of the breast, (concealed by 

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

 tinged with sulphur yellow. Entire crown from the base of the bill to a well developed occipital crest, as also a patch on the 

 ramus of the lower jaw, scarlet red. A few faint white crescents on the sides of the body and on the abdomen. Length, about 

 18 inches ; wing, 9j. 



Female without the red on the cheek, and the anterior half of that on the top of the head replaced by black. 



Hob. — 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.
