The general impression we derive from a study of the series is that the amount of white on the wing and elsewhere decreases from the Missouri River to the Pacific, exhibiting its minimum in Oregon and Washington, precisely as in the small black Woodpeckers; that in the Great Basin the size of the claws and the length of tail increases considerably; that the northern forms are entirely black, and the more southern brown or olivaceous, except on the head.
The following synopsis will be found to express the principal characteristics of the species and their varieties, premising that P. arcticus is more distinctly definable than any of the others. We add the character of the green-bodied Mexican species to complete the series.
1. Wing, 3.65; tail, 4.20. Outer tail-feather with terminal half of inner web white. Iris bright red, sometimes paler. Hab. Eastern Province United States. (Florida in winter.) … var. erythrophthalmus.

Upper parts generally, head and neck all round, and upper part of the breast, glossy black, abruptly defined against the pure white which extends to the anus, but is bounded on the sides and under the wings by light chestnut, which is sometimes streaked externally with black. Feathers of throat white in the middle. Under coverts similar to sides, but paler. Edges of outer six primaries with white at the base and on the middle of the outer web; inner two tertiaries also edged externally with white. Tail-feathers black; outer web of the first, with the ends of the first to the third, white, decreasing from the exterior one. Outermost quill usually shorter than ninth, or even than secondaries; fourth quill longest, fifth scarcely shorter. Iris red; said to be sometimes paler, or even white, in winter. Length, 8.75; wing, 3.75; tail, 4.10. Bill black, legs flesh-color. Female with the black replaced by a rather rufous brown.
