Laelaps cristatus , Cope, sp. nov.

Another small species well distinguished by the form and coarse denticulation of the teeth, approaching the genus Troodon . The crowns of the teeth are short, stout, compressed, and curved. Both sides are convex, and neither is iheetted. The dentieles are large, those of the posterior cutting edge the largest, and measuring M..0005. A characteristic feature is the full development of the (lenticnlate anterior cutting edge of the crown. This extends to the base, becoming more prominent as it descends. Surface smooth.
