The exact provenience of the six men measured at Marshall is uncertain, but they seemingly were all from the lower Yukon and all were apparently full-blood Eskimo. But the measurements are rather peculiar. They are given, for comparison, with those of the western Eskimo in general (p. 165). They approach nearest to those of the Togiak Eskimo, well down below the Kuskokwim. They show a higher stature than all of their relations farther south, except the Togiaks, and they have a rounder head. They are, in fact, moderate brachycephals, a very unexpected form in this strain of people. The Togiaks also are brachycephalic. The vault is relatively somewhat higher than it is in the other groups, though the height is not excessive. The nose is slightly lower as well as narrower than it is in all the other contingents. The face is close to those of St. Lawrence Island. The ear is perceptibly smaller and especially narrower than elsewhere, but perhaps the age factor enters into the case. The hand is much like that of Togiak and St. Lawrence, the index being identical. The brachycephaly of the group for the present is hard to explain. It can not be ascribed to a mixture with the river Indians, for these, as has been seen from the skulls, were meso- rather than brachycephalic. There is need here for further inquiry. SKELETAL REMAINS OF YUKON ESKIMO As with the Indian, such remains are still rare. Some measurements of three "Smithsonian Mahlemute" skulls from the Yukon, collected by William H. Dall, are given by Jeffries Wyman, and probably the same specimens appear in the Otis Catalogue, the measurements in which are regrettably not very reliable. These specimens can not now be located, and the scarce data are of but little value. The three skulls examined by Wyman were all mesocephalic. It is now possible to report on 40 adult skulls from the lower Yukon and the delta. An abstract of the measurements is given in the next table. The data indicate a considerable local variation. All the skulls, or very nearly all, are mesocephalic; but they differ considerably in height and in all the facial features. The Pilot Station group, from the apex of the delta, and hence the midst of the Eskimo territory on the Yukon, is especially peculiar. Both the vault and the face, in the series as a whole, range from low to high, and much the same is true of the height of the nose and that of the orbits, while the palate is exceptionally broad, giving a low index, all of which would seem to indicate instability or conditions in change, together probably with admixtures from farther up the river. We need more material, particularly from the stretch of the river between the apex of the delta and Paimute. YUKON ESKIMO CRANIA UNITED STATES NATIONAL MUSEUM:
