Abstract
THE skull of a remarkable new generic type of horned dinosaur (Styracosaurus albertensis), from the Cretaceous of the Red Deer River, Alberta, is described and figured by Mr. L. M. Lambe in the Ottawa Naturalist for December, 1913 (vol. xxvii., pp. 109–16, plates x.–xii.). o It was found by the well-known collectoi Mr. C. H. Sternberg, last summer. The skull is long, depressed, and wedge-shaped, with a single nasal horn of somewhat unusual shape; but its chief peculiarities are the large size of the supra-temporal fossæ, and the production of the hind border of the great occipital flange into four pairs of spines, of which the three innermost on each side are very long. Although the Alberta horned dinosaur may be generically identical with an imperfectly known species from the Cretaceous of Montana, referred by Cope to the genus Monoclonius, under the name of M. sphenocerus, it is considered that the two are specifically distinct.
