Description of new carnivores from the Miocene of western Nebraska descriptionofnew45pete Year: 1910 PETERSON : NEW CARNIVORES FROM MIOCENE OF WESTERN NEBRASKA 227 unfortunately not completely preserved; enough remains, however, to determine that it is fully as heavy as in Canis, but probably did not attain the length seen in the latter. The pre- and postzygapophyses, especially «lfce 5- \ §Sm»tvi the latter, are much expanded in comparison with those of the preceding lumbars, and the neural spine is also quite light, although comparatively heavier than in the recent dogs. In the type of Gynodesmus brachypus the lumbar series (seven) is apparently completely represented. The centra, especially in the anterior part of the series, are somewhat FlG- 22- Seventh Lumbar less depressed than in Daphcenodon. The transverse pro- Vertebra of a s'perbus- nat. size. cesses, though relatively longer than in Daphcenodon, are not attenuated to the same degree as in recent dogs. The metapophyses, anapophyses, and neural spines are proportionally lighter than in Daphcenodon and on the whole more nearly resemble the lumbar vertebrae of Canis. Measurements of Seventh Lumbar Vertebra. Mm. Antero-posterior diameter of centrum 34 Transverse diameter of centrum posteriorly .... 31 Vertical diameter of centrum posteriorly 18 Transverse diameter at transverse processes, approximately 72 Height of neural spine 33
