Top of spine to inferior border of neural arch, 35 " 1% " The Dorsals.—The presence of the heavy capitular facets situated far down on the anterior border of the neural arch, together with the presence of a single spine would indicate that this vertebra l^elonged well back in the dorsal series. The spine which wants the su- perior portion has a posterior position. The superior blades of the postzygapophysial laminae are very heavy while the inferior are of weaker construction and descend to form the posterior walls of the neural canal. The transverse processes are well ex- panded and extend upward and forward as shown in Figs. 9 and lamina ; pzl., postzygapophysial lamina ;. Fig. 8. Dorsal of Elosazirus parvus.
