There is an indication by an ascending groove of a small ascending talon, making some approach to Dimosaurus. The tibia on slab 63 shows less than 6 inches of its proximal end, which is only 2 inches wide, and has the cnemial crest defined by a small superior cavity, which is continued down- ward by the fibular groove on the external aspect. The shaft of the bone is about ich appears to be expanding slightly towards tlie distal fracture. The Fihula o/Palasosaurus. (Fig. 6.) A bone which I regard as being the left fibula agrees closely with the tibia in its length, is of about the same dimensions as the tibia no. 76 in the shaft, though but little expanded at the proximal and distal ends. It may have belonged to a species with rather more robust bones, such as is indicated by the slab tibia, no. 63. The distal extremity, which is exposed in lateral is strong and moderately expanded, like the distal end of the tibia no. 76, which it resembles in size. It has a convexly truncated distal end, which is about ly^^ inch wide. The bone is somewhat imperfect in fracture, but has a slender shaft | inch wide, with subparallel sides; the oblique proximal end widens to about.
