Carnivora, Fossil; Paleontology; Paleontology. 226 MEMOIRS OF THE CARNEGIE MUSEUM is a curious feature of this genus which seems to have departed from Daphcenus, Temnocyon,u and also from the recent canids generally, while, according to observa- tions by Dr. Matthew (/. c, p. 367) upon Miacis, its affinity with regard to the short transverse processes would seem to recall the earlier tertiary types. As in Daphcemis the metapophyses, anapophyses, and neural spines are proportionally more robust than those in the recent dogs.

As in Daphcemis the metapophyses, anapophyses, and neural spines are proportionally more robust than those in the recent dogs. The meta- and anapophyses are heaviest on the first lumbar and gradually decrease in size backwards, the anapophysis of the fifth lumbar being quite small. Except on the first, second, and seventh lumbars the neural spines are broken off superiorly, but enough remains to ascertain their great anteroposterior diameters, which are not unlike those in canids generally.

Sixth Lumbar Vertebra.—The sixth lumbar ver- tebra is characterized by the absence or very rudi- mentary development of anapophyses, and also by a considerable transverse broadening of the centrum posteriorly. There is otherwise very little difference between this vertebra and the one preceding it. Flo. 21. Sixth Lumbar Vertebra of D. superbus. \ nat. size. Measurements of Sixth Lumbar Vertebra. Mm.
