. The Bashford Dean memorial volume :. Fishes; Sharks; Fishes, Fossil. 670 Bashford Dean Memorial Volume Jaws and Teeth.—Goodrich (1909) contributes an outline drawing of an in- complete skull of Heterodontus pMlipi, here reproduced as Text-figure 33, page 700. This drawing is introduced primarily to show the mode of suspension of the jaws; but when we compare this figure, showing these jaws in lateral aspect, with other figures (Text-figures 10, 11 and 14) showing them in dorsal and ventral aspects, we are impressed by their massive pincer-like character—somewhat like the jaws of Heptanchus outlined by. Text-figure 10. Teeth of the Port Jackson Shark, Heterodontus pMlipi. Whether the figure represents an upper or lower jaw is not stated, but apparently it is a lower jaw. After PhiUip, 1789, pi. feeing p. 283. Goodrich, 1909, Fig. 59a. One can readily imagine how powerful these jaws are when equipped with, the grinding teeth—set well back toward the angle of the jaws—and with the musculature necessary for crushing the shells of molluscs that form the principal food of this species of Heterodontus. Garman also (1913, Atlas, Fig. 4, pi. 47) has figured the jaws of Heterodontus pMUpi in lateral view, but in form so different from Goodrich's portrayal that one might think the two drawings were made from different species. Phillip's drawing (1789) of the teeth of the Port Jackson Shark is reproduced here as Text-figure 10. The author does not state whether this is an upper or a lower jaw, but upon comparison with, the figures of Striiver (1864), Maclay and Macleay (my Text-figure 11) and McCoy (my Text-figure 14) it appears to be a lower jaw.
