. Description of new carnivores from the Miocene of western Nebraska. Carnivora, Fossil; Paleontology; Paleontology. PETERSON : NEW CARNIVORES FROM MIOCENE OF WESTERN NEBRASKA 243. Fig. 41. Internal View of Right Half of Pelvis of D. superbus. I nat. size. The Hind Limb. (Plate LXXVIII and Plates LXXXI-II.) The pelvis of the type is represented by the greater part of the ilium, while the ischium and pubes are represented only by the portions surrounding the acetabu- lum. In a larger specimen of Daphcenodon which belongs to the Amherst College the innominate bone is more nearly complete (see PI. LXXVIII), but the posterior portion of the ischium is also lacking in this specimen. In comparing the pelvis with Professor Scott's description of that in Daphasnus (I. c, pp. 349-350) it is evident that the similarity in the two genera is quite close. As in the Oligocene genus the gluteal surface of the ilium is divided by a prominent longitudinal ridge, unlike that in recent dogs, or cats where the surface is more evenly concave. The ilium is less expanded at the supra-iliac border than in Canis, but probably somewhat more so in comparison with that in Daphcenus. The ilium, as a whole, is relatively broader than in the tiger or lion, and is not unlike that in Viverra zivetta, as was also observed by Professor Scott in his study of Daphasnus. The attachment for the sacrum is quite heavy and is situated well back. The ischial border and the great sacro-sciatic notch is short. The iliac sur- face is not well defined on account of the short pubic border; the ilio-pectineal eminence however, is, well developed. The acetabular border is very prominent and terminates in a large tubercle at the anterior border of the acetabulum. The latter is of moderate size and depth, the center of the floor being occupied by a large depressed and roughened area, which indicates the attachments of a large cushion of fat as well as the ligamentum teres of the femur. The cotyloid notch is quite bro
