S. B. McDowell and C. M. Bogert 1954Splenial with reduced posterior extent, not extending back to the level of the apex of the coronoid process, forming a vertical suture with the angular at the level of the dentary-surangular suture; Meckelian groove open for a considerable distance be- tween the dentary and the splenial; external bony naris extended back as a slit in the bony roof of the muzzle lateral to the nasal, this slit reaching or almost reaching the frontal; maxilla extending but a short distance beneath the eye or not at all, the maxillary tooth row entirely preorbital; proximal bases of the teeth expanded and sculptured with a fine vertical fluting.
