740 U. S P. R. R. EXP. AND SURVEYS—ZOOLOGY—GENERAL REPORT. 
preceding was first pointed out by Dr. Heermann in the Proceedings of the Philadelphia 
Academy, as above cited. 
In suggesting the close relationship of this bird to the sub-genus Prosobonia of the Prince 
Bonaparte, we are guided mainly by Professor Schlegel’s beautiful figure of Z’ringa leucoptera, 
Gmelin, on which it is founded, and also by specimens before us of Z’ringa brevirostris, Peale, 
which evidently is of the same group. Both the species here mentioned are from islands in 
the Pacific ocean. 
Dr. Heermann’s type specimen of his Actidurus naevius differs somewhat from the ordinarv 
plumage, in the much coarser mottling of the primary quills.

Section LIMOSEAE. 
LIMOSA, Brisson. 
Limosa, Brisson, Orn. 1760. Type Scolopax limosa, L. 
Cu.—Bill lengthened, exceeding the tarsus, slender, and curving gently upwards; grooved to near the tip; the tip not 
attenuated, but pointed ; the lower almost as long as the upper. Culmen without any furrow. Tarsus with transverse scutellae 
before and behind, reticulated laterally. A short basal membrane between the middle and outer toes. Tail short, even. 
Bill much longer than head, nearly equalling tarsi and toes together; curving gently 
upwards from the base, where it is elevated and compressed, depressed, however, at the end. 
The grooves on sides of bill and beneath extend nearly to the tip; the tip of the upper 
mandible is thickened, and extends a little beyond the lower. The gape is slight, not 
extending beyond the base of culmen; the feathers on the side of the bill reach forward to 
about the same point, those on the chin a little further. Tarsus more than 1} times the toes, 
twice the bare part of tibia. Hind toe lengthened. Outer toe webbed as far as end of first 
joint, inner toe with only a short basal web. Tail short, even, two-fifths the wings. 
In some respects the bill of this genus resembles that of Macrorhamphus, the chief apparent 
difference being the upward curve of the one and its straightness in the other.
