The shaft is considerably contracted in the middle portion. The anterior face of the distal end is flattened and even concave ; the posterior face has a very deep groove separating the two condyles. The articnlar faces of the condyles look well forward and are connected by a wide area, not separate as in Dimetrodon. The outer condyle is longer than the inner. The tibia is slightly curved and has a greatly enlarged proximal end, but the articular face is not so nearly divided into two parts by a depression as in Fig. 25 a.—Sketch restoration of Theropleura relroversa.
