note: a comma denotes an abrupt change in tooth size and/or shape; the symphysial teeth are separated by a dash).

Upper teeth broadly triangular, oblique; some teeth with sinuous medial margin; medial and lateral margins serrated along entire length, serrations coarsest basally; medial margin convex, lateral margin concave but not notched in most intact teeth, some becoming convex at the base; symphysial teeth very small, triangular; first tooth distinctly smaller than those in next 6 rows; last tooth strongly oblique, much smaller than all other functional rows.

Base of 4th tooth on right of upper jaw 21.98 mm, height 14.9 mm (base 1.47 times height); base of 5th tooth on left of upper jaw 22.29 mm, height 15.7 mm (base 1.42 times height).

Lower teeth erect (weakly oblique laterally), narrow; margins almost parallel, then tapering rapidly to the tip; margins with fine serrations along entire length. Symphysial teeth lanceolate.

Internal dimensions of jaw: height 37.5 cm, width 28 cm.

Writing in Tales of the Angler's Eldorado: New Zealand Grey (1926) reports landing two large Carcharhinus sp., which he identified by the Maori name reremai, off Cape Brett in March 1926, and that Captain Mitchell broke off a ‘colossal’ reremai at Sunken Reef, Bay of Islands on 23 March 1926. The weights of the sharks landed were 172 kg and 128 kg. It is possible that the larger of these two sharks is the source of these jaws but unfortunately as C. brachyurus exceeds 180 kg (pers. obs.) its not possible to confirm this without further evidence. Grey (1926) reports landing five Carcharhinus sp. (4 off Cape Brett, 1 off the Cavalli Islands) in February 1926. The largest of which was caught off Cape Brett and weighed 318 kg, and two others exceeded 200 kg. The 318 kg fish is figured in Plate LXXXVII – its size and relatively small dorsal fin make it a more likely candidate but without an image of the teeth or one showing the interdorsal ridge this can’t be confirmed.
