Researches on the Structure, Organization, and Classification of the Fossil Reptilia VII Further Observations on Pareiasaurus . internaltrochanter as to suggest that the bone may be an Anomodont femur.—July 15,1892.] AND CLASSIFICATION OF THE FOSSIL REPTILIA. 353 flattened and widened. The bone is imperfect distally on its outer side, and on theright side it is somewhat compressed from side to side. On the superior surface there isa median distal groove, which leads down to a foramen about half an inch long andrather narrower; this has the same position as the foramen at the distal end of thefemur of Propappus (Fig. 10). It is a true canal, and not a notch like that seen atthe distal end of the femur in certain Ornithischian Reptiles, such as Orthomerus andIguanodon. An inch and a half below the foramen, a median notch in the bone(Fig. 9), as in Propappus (Figs. 10, 11), defines the distal internal articular surfacefor the tibia c, from a smaller external surface for the fibula (Plate 22, fig. 2, c%). Thedistal condylar articulation for the tibia is oblique, as in Propappus, but instead of Fig. 10. Fig.
