The holotype of this species is shown from the left lateral aspect in Plate LXVIII, Fig. 2, somewhat larger than natural size. A portion of the squamation having adhered to the opposite half of the containing matrix, the scales are seen from the inner side in the only part of the specimen which is now preserved. They are semitranslucent, and the remarkably strong denticulations are visible through the thickness of the overlapping series. Family PYCNODONTID^. Genus Mesodon Wagner. 25.
