X 1- summit of this ridge is about 5 mm above the general dorsal surface. Tlie anterior margin of the supinator process projects shaq^h' from the general surface of the bone. The distal surface of this process is blunt and faces forward. It is at about the level of the entepicondylar foramen, as in all peh'cosaurs, but well beneath the ect- epicondxle and separated from it hv a deep ectepicond\'lar grooxe. The ectepicondy- lar notch is relatively shallow. The radial articulation was broken off and only a small part of the ulnar articulating surface is seen. In block D there is a femur that can be associated with this animal. This bone, 42 mm in length, seems to have belonged to an immature individual, since neither the prox- imal nor the distal head—so important in characterization—are well ossified. A rudi- mentary' adductor crest is \'isible on the ven- tral side of the femur. Even in this im- mature state, this femur is longer than the humerus in block B. There are few features in this particular femur to compare with the femora in other pelycosaurs. An almost complete calcaneum is found in the same fragment in block D as the interclavicle (RM 10056). This element is weakh' ossified and the proximal end is crushed in such a manner that this region is shifted to the right. The area where the perforating foramina would be expected.
