. Description of new carnivores from the Miocene of western Nebraska. Carnivora, Fossil; Paleontology; Paleontology. PETERSON : NEW CARNIVORES FROM MIOCENE OF WESTERN NEBRASKA 265. facet for the scapho-lunar is slightly convex from before backward near the dorso- radial angle, while further back and along the ulnar portion it is concave in the same direction. Radially there is a large facet for the trapezium, which takes up nearly the entire face. On the ulnar side the facet, for the lunar, meets that for the magnum at an acute angle so as to form a prominent ridge, which extends a short distance back from the dorsal border. Back of the ridge the ulnar face is taken up by a large rugose area for the at- tachment of muscles and ligaments. On the distal face there is a large subtriangular articulation for the second metacarpal. The free end of the pisiform indicates this bone to be quite like that in Daphomodon. Mc. I has the head less expanded transversely, the shaft less arched forward, and less curved outward at the distal end than that of Dapluenodon superbus; there is otherwise little or no difference between this bone in the two forms. Other fragments of the metacarpals suggest heavy bones in this region. The phalanges are proportionally short when compared with Daphosnodon. Those of the proximal row are other- wise arched in the dorsal direction similar to the conditions found in the latter genus, while the median phalanx is depressed and broad. There is no ungual pha- lanx present with the type. The hind limb is represented by the lower half of the tibia and fibula, the astragalus, navicular, ento-, meso-, and ectocuneiforms, and other fragments. With the exception of the proportionately somewhat greater antero-posterior diameter of the distal end, the tibia offers little or no characteristic differences by which it may be distinguished from that of the smaller genus. The distal end of the fibula is more compressed laterally than in Daphoenodon; otherwise ther
