. The Bashford Dean memorial volume :. Fishes; Sharks; Fishes, Fossil. 668 Bashford Dean 'Memorial Volume. Text-figure 8. Lateral view of a very young (recently hatched) female specimen of the Port Jackson Shark, Heterodontus phillipi, about 225 mm. ( inches) long, drawn while fresh.

The entire color pattern is more distinct and somewhat more complex in this young specimen than in the adults. Concerning this specimen Maclay and Macleay wrote: "The very remarkable marking, the rounded form of the head and the proportionally large tail are peculiar to this stage". From the dorsal view of this specimen, we see that the head is not so broad, proportionally, as in the adult. McCoy (1890) contributed two figures, in color, representing side views of male and female specimens of Heterodontus phillipi. The delicacy of the outlines of these drawings makes them unsuitable for reproduction here. In these figures the color pattern is not well shown, but McCoy's detailed description of the distribution of the dark-brown stripes corresponds closely with the pattern shown in Maclay's drawings (lateral and dorsal views). According to McCoy the dark'brown bands are most distinct in the young, nearly obsolete in the old, and invisible in stuffed, dried, or spirit specimens. The photograph of the Port Jackson Shark by Saville-Kent (1897) is reproduced as my Text'figure 4, page 658. The specimen was alive when photographed. The original figure measures six and onchalf inches long and is said to be one-tenth natural size. This would make the shark over five feet long. If the reduction is accurately stated, this is the largest Port Jackson Shark on record; but experience shows that one cannot always depend on records of this kind. Waite (1898) collected specimens of the Port Jackson Shark, Heterodontus phillipi, from 14 difi^eren
