Text-figure 8. 



Lateral view of a very young (recently hatched) female specimen of the Port Jackson Shark, 



Heterodontus phillipi, about 225 mm. (8.8 inches) long, drawn while fresh. 



After Maclay and Macleay, 1879, Fig. 5, pi. 23. Right and left are here reversed. 



ously; but to me it seems likely that it was about two weeks old. 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^erent stations, and records that none of the specimens was longer than two 

 feet. The majority were but little over 18 inches. He states that this shark is not known 

 to grow longer than four and one-half feet, and that it is harmless.
