PECTORAL GIRDLE (Fig. 12) 26) Pectoral girdle inferred arciferal. 27) Clavicles and coracoids strongly di- vergent. 2(S) Coracoids with strong shafts ex- panded at both ends. 29) Clavicles large and strongly arched. 30) Clavicles and coracoids meet mid- ventrally. 31) Scapula small and mostly uncleft. 32) Suprascapula a large petaloid blade. 33) Cleithrum large, V-shaped. 34) Sternum, episternum and coracoidal cartilages absent. PELVIC GIRDLE (Fig. 11) 35) Pubis ossified. 36) Ilia long in Thoraciliacus, relatively short in Cordiccphalus. 37) Pelvic articulation either iliocostal (= medioiliac, in Thoraciliacus) or acroiliac (in Cordiccphalus). 38) Ischium relatively long. 39) Epipubis absent. FORELIMB (Fig. 13) 40) Humerus straight, mostly smooth, having a well-developed spherical capitate eminence. 41) Radioulna single, flat, expanded at both ends, having a prominent olec- ranon. 42) Nine free carpals. 43) Four fingers with very long meta- carpals, 2, 2, 3, 3 phalanges, the terminals being pointed. 44) Prepollex represented by its carpal only. HINDLIMB (Fig. 13). 45) Femur faintly S-shaped, having a low, short femoral crest. 46) Tibiofibula single, strong, slightly shorter than the femur. 47) Tibiale and fibulare are elongated, fused at the two ends. 48) Five free distal tarsals. 49) Five toes with very long metatarsals,.
