1878.] NATURAL SCIENCES OF PHILADELPHIA. 21 NOTES ON THE NATURAL HISTORY OF FORT MACON, N. C, AND VICINITY. (No. 4.) BY DR. ELLIOTT COUES AND DR. H. C. YARROW. When the present series of papers was projected, it was intended that they should give a full account of the zoology of the locality, as studied by the writers during their successive residence at Fort Macon. Dr. Cones was Post-Surgeon at the Fort during 1869 and 1870, being succeeded in the winter of 1870-71 by Dr. Yarrow, who took up the work immediately and continued it until 1872. Dr. Cones has already published two papers in these Proceed-ings (1871, pp. 12-49, and pp. 120-148), one on the Mammals, Birds, and Reptiles, the other on various Invertebrates, chiefly Mollusks. More recently, Dr. Yarrow has published (1877, pp. 203-218) a third paper, on the Fishes, giving the joint results of our respective collections though it should be added that the observations are entirely those made by Dr. Yarrow, he having been furnished by Dr. Cones with simply a list of the species col-lected by the latter, as identified by Mr. F. W. Putnam, of Salem. The present paper, No. 4 of the series, supplies many omissions in the first article, on the Mammals, Birds, and Reptiles more particularly the latter. The series of papers may be completed by another communication, supplementing Dr. Coues's article on the Invertebrates (No. 2) witli the results of Dr. Yarrow's more extended observations on several classes of the lower animals. The writers are indebted to Prof. E. D. Cope, for identification of some of the Reptilia and Batrachia given in the present article. I. MAMMALS. Ursus americanus, Pall. Black Bear. Common on the mainland near Fort Macon ; and is also found abundantly in a large marshy piece of ground not far from Croa-tan, a station on the North Carolina Railroad. Numbers are taken during the fall and spring in large iron spring traps, their meat and fur finding a ready market at New Berne, N. C. Some skins seen show small patches of light grizzled fur resembling somewhat that occasionally seen in specimens of U. americanus from the Rocky Mountains.
