Sci., xxiii., 1923, p. 67, pi. i.) from the Philippines, has small nasal flaps: and teeth more as in Triakis, with small cusps on each side of the central fangs. Fur macki sp. nov. Snout bluntly rounded, profile acute. Nostrils large, with nasal flaps which do not reach the crescentic mouth. Eye moderate with small pupil. Nictitating fold as long as eye. Spiracle small. Teeth in upper jaw rather like those of the School Shark, Notogaleus; but with four acute cusps on outer margin of each, the deflected inner margins smooth. There appear to be several small erect points on the upper symphysial teeth. Teeth of. Fig. 1. Shark, Fur macki. Holotype, Mordialloc, Victoria. Also teeth and ventral surface of head. G. P. Whitley, del. lower jaw each with a single median cusp, acute and suberect, with broad, entire bases. Several functional series in each jaw but dentition weaker at symphyses. Upper labial folds longer than lower. First to third gill- openings subequal, longer than fourth and fifth. Last gill-slit over pectoral base. Head and body together shorter than rest of shark. Form deep anteriorly, tapering posteriorly, caudal axis not much elevated. No inter- dorsal ridge but a rather shallow groove. No caudal pits. Shagreen dense and hard, denticles varying from tricarinate on dorso-lateral surfaces to sm
