There are four roots of functional incisors, No. 1 shows only the tip of a root lying in an alveolus from which it is just about shed, and intero-lingually lies a well-developed replacing incisor already occupying the functional alveolus. The other three incisors, as well as the canine, have the inner alveolar walls strongly developed as encasing sheaths. The flange of the dentary extends high up to almost meet the inner face of the alveolar walls at a high level. The canine has a large root, which in outline is a long pinched-in ova] with diameters 47 and 27 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
