Plate XXI, fig. 9 . The strongly keeled and highly ornamented shield shown on plate XXI , apparently represents an ancient sturgeon, for which the above name is proposed. The ornamentation consists of rounded, coalescent ridges and nodes in high relief, and quite smooth, not very unlike the sculptured surface of the shell of some species of turtles. This genus has not hitherto been known from rocks lower than the Tertiary. Belly Eiver series, Eed Deer river, District of Alberta, 1901.
