. Contributions to Canadian palæontology. Paleontology. 52 "With the left ramus, above described, is arbitrarily associated, as probably referable to the same species, the abbreviated coossified nasal bones figured in plate VI, fig. 3, (collection, of 1904). The specimen includes the bases of the horns which are seen to have been placed far forward and some distance apart. The horns apparently pointed laterally outward and upward, as in M. angastigenis and M. coloradensis, but were much farther forward than in either of these species. These nasals are entirely different from those of M. selwynianus, and M. syeeras ; they are short, thick, and broadly obtuse in front where they are but slightly bent downward. The front and lateral margins are thick and rounded, and the former is deeply notched in the middle. The lower surface is, as a whole, shallowly concave, a low longitudinal median ridge marking the line of union of the two bones. The concave surface between the horn bases is shallowly and evenly curved. The horns at the base appear to have been longitudinally oval in transverse section, but a definite statement in this regard cannot be made, as the horn bases are imperfect posteriorly. The specimen is, on the line of coossification of the two bones, 70 mm. back from the front margin, 44 mm. thick. The shortness and general robustness of the nasals, with like characters noticeable in the proportions of the above ramus, makes it appear probable that these specimens represent a single species.
