Cope, Proc. Am. Phil. Soc, vol. xxx, 1896, p. 456. Type: An imperfect skull. No. 4471 Am. Mus. Nat. Hist. Cope Coll. From Texas. Original description: "The character of the species is seen in the horns. These are much less produced relatively to other regions than in the D. magnicornis, and the postquadrate (quadratojugal) element is more distinct and terminates in a separate apex below the principal horn. This tract, which is fused with the principal bone in the D. magnicornis,^ is separated from it by a groove in the D. limbatus, and the large fossa which it incloses with the inferior side of the principal horn looks inward at an angle of 45°, while it looks downward in the D. magnicornis. The terminal angle of the post-quadrate (quadratojugal) body forms a prominent compressed offset, rather than a free apex. In one specimen of large size it is inferolateral; in type, entirely inferior. The principal horn is shorter and narrower than in the D. magnicornis, and less divaricate. "As the mandibular rami are in place and their extremities are entire, the length of the muzzle can be inferred. It is relatively longer and less broadly rounded than in the D. magnicornis. Ti^e surfaces of the skull are sculptured in a honeycomb pattern, as in the type species.
