The trans- verse process is heavier than in Cams lupus. The postzy- gapophyses point forward and outward in a greater degree ; their zygapophysial articulations are larger and present a more obliquely concave appearance than in the later genus, while the postzygapophyses are quite similar in every re- spect. The neural spine is robust and high, but on the whole proportionally lighter than in Cams. The excava- tions on the spine referred to in the description of the pre- ceding vertebra are also continued to the dorsal series, and in his description of Daphoenus (I. c, p. 339) Scott speaks of this condition as follows : " the notch between them [prezy- gapophyses] is very deeply incised, invading the base of the spine, a very different arrangement from that seen in ; Fio. 12.

Ventrally there are two prominent ridges on either side of the median keel, which extend nearly the entire length of the centrum. The transverse process and the zygapophyses are lighter than on the preceding verte- bra. The prezygapophyses face inward and slightly upward ; at their lower margins they are abruptly c
