Natural history. 138 ANNALS OF THE SOUTH AFRICAN MUSEUM expansion and a long broad posterior spatula joined by a fairly narrow neck at the level of the posterior coracoids. Priesterognathoides (figs, ii and 12a) In 12102 the right half of the pectoral girdle is preserved together with an incomplete interclavicle and parts of the left half of the girdle. The girdle is partially disarticulated but only slightly distorted in its fall backwards when the soft tissues decomposed. In 12204 a disarticulated girdle has a good scapula, coracoid, procoracoid, interclavicle and the ventral spatulate ends of the clavicles. The scapula is apparently tilted somewhat backwards and shows a marked curvature around the thorax. No origin of the triceps can be determined and there is definitely no tubercle. The coracoid is short, but the procoracoid well developed. The interclavicle is very similar to that of Alopecognathus. Pristerognathus (fig. 12b and c) In 4335 there are a pair of incomplete scapulo-coracoids. The coracoid is short and the procoracoid well developed. No scar or tubercle for the scapular. Fig. 11.
