Sci. toot, Vol. XI, p. 82) in order to avoid anticipating my previously written but until now unpublished work on the subject. matter, I think it will avoid possible confusion to use his name, as it was published with a valid definition, While appreciating his courtesy in the Fig. 18..lIzryeoe/ra'ru.rfiroprius. Skull, side view, x I. No. 8968. White River Formation, Leptauchenia Beds, Colorado. The special characters of the fllerycocfiwrus skull indicate that the animal had a large proboscis of some kind, of a character quite unparalleled among Ruminants, and not very closely paralleled by the Elephant or Tapir. The evidence is: I.--Great reduction of the nasals, extending the flexible part of the snout. Development of rugosities and ridges for strong muscular attachments immediately in front of the orbits; these give rise to the muscles controlling the motions of the upper lip and the flexible parts of the nose. 2.--Complete coossification of the premaxillae with each other and with the maxillae into a solid mass of bone, pierced by a single anterior palatine foramen. This gives the solid fulcrum necessary to wield a heavy proboscis. 3.--Great broadening of the occipital wings and of the mastoid process of the squamosal, giving power and leverage to the muscles controlling the motion of the skull on the vertebral column. This increased power is obviously necessary in order to control the correspondingly increased length and size of the snout. 4.--Extensive development of cellular bony tissue in front of the broad occiput, serving to brace the flanges of the transverse crests and the...
