Laelaps falculus , sp. nov.

Represented by several teeth of about half the size of those of the last described reptile. They differ in form in several respects, being relatively shorter and stouter, and less sectorial in character. The lateral surfaces are about equally convex, while the aniterior face is narrowly obtuse, and without cutting edge. The posterior edge is concave and furnished with a seriation of smnaller denticles than in the L. explanatus ; it is median in position.
