Carcharias brachyurus, Günther, Cat. Fish. Brit. Mus., viii., 1870, p. 369. Carcharias macrurus, Ramsay and Ogilby, Proc. Linn. Soc. N.S. Wales, (2), ii., 1887, p. 163. Dr. Günther's description was based upon a stuffed example, and under the circumstances, such plastic characters as the shape of the mouth and the snout can scarcely be regarded as affording reliable specific characters. Messrs. Ramsay and Ogilby, however, draw attention to these features as providing recognisable points whereby to distinguish a species described as new.
