Homo sapiens, specimen showing fovea anterior. Tarsius spectrum, The small size of the canine is a character shared with Parapithecus. Its shape is in all probability primitive (Remane, 1927, 1955) (Text-fig. 12); it shows much resemblance to the female canine of Pliopithecus (Hurzeler, 1954a, fig. 10). Though a precanine diastema is usually well developed in Pongidae, it is very short in the female skull of Proconsul africanus (Le Gros Clark & Leakey, 1951). 4. Comparison with Hominidae. Hominid teeth are notoriously variable, and for considerations of space it is necessary to confine attention to those features that are sufficiently frequent to be regarded as characteristic. The material studied consisted mainly of the teeth of Europeans, Australians, Pithecanthropus pekinensis and Australopithecinae, the last two groups seen only as casts. Hominid upper molars show numerous differences from those of Oreopithecus : (1) They are nearly always broader than long, and thus resemble the majority of Pongidae. Oreopithecus is specialised in the elongation of its 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 British Museum (Natural History).
