. Carnegie Institution of Washington publication. . <77- .78. 179. -Osteopygis platylomus. Peripherals and sections. Type. Xj. 175. Sixth, seventh, and eighth right peripherals. tt6. First, second, third, and fourth right peripherals. 177. Sections of first and second left peripherals, a, distal end of second ; h, proximal end of second; c, near proximal end of first. 178. Hinder end of eighth peripheral. 170. Front end of eighth peripheral. 180. Section along right articular border of the pvgal. extended laterally to about the middle of the first peripheral. The eleventh reacht laterally the hinder border of the pit for the last rib. I he costo-marginal sulci run along on the upper borders of the first and second peripherals, then disappear, to reappear on the upper borders of the eighth to the eleventh. From the third to the eighth peripherals the sulci occupied doubtless the space between the costals and the peripherals. At present there remain of the plastron only a part of the left hyoplastron, most of the left hypoplastron, and most of the right xiphiplastron. The plastron seems not to have differed in any important way from that of O. borealis. Evidently there was a fontanel between the hvoplastia in front and the hypoplastra behind. At the narrowest part of the bridge the hypo- plastron is 58 mm. wide. The thickness at the inguinal notch is 16 mm. No sulci are to be seen on these bones, except a faint one near the base of the xiphiplastron. To the present writer it seems evident that the bones on the right of Cope's figure of the plastron of this species.
