This curious feature of articulations in the tarsal bones is quite unusual and is also found in Daphcenus and to a less degree in Hoplophoneus, as Mr. Hatcher observed in his study ('The Oligocene Canidae,' p. 91). In the middle region of the tibial face is the third facet, which is of considerable size ; it is triangular in outline and articu- lates with the ectocuneiform. Proximally the cuboid has a large surface for the calcaneum, which is convex in all directions in a greater degree than in Canis or Felis and even more than in Hoplophoneus, though not nearly so oblique as in the latter. Distally there is one large facet for metacarpals IV and V, which is concave antero-posteriorly and also slightly concave laterally, the extreme fibular border being slightly recurved upward to accommodate the lateral portion of the proximal facet of Mt. V. Measurements of Cuboid. Mm. Greatest antero-posterior diameter 20 Greatest transverse diameter 17 Greatest vertical diameter 21 Metatarsal I. — The first metatarsal has the appearance of being shorter than that of Daphcenus when placed in position in the pes, but it is in reality of very nearly the same proportionate length, this shortened appearance being chiefly due to the proportionally less vertical diameter of the entocuneiform in the Miocene genus. These bones (Mt. II) in the two genera are very similar in every respect. As in Daphcenus the head is much expanded both antero-pos- I(V,'IiSm teriorly and transversely, with two prominently developed I Mr and rugose tubercles on the plantar face, one on the tibial and t e other on the fibular angle.
