criticised by Maclay and Macleay (1879;, who alleged that it is so unlike the fish it is 

 intended to represent as to suggest a doubt of its being the same species. In 1884 Maclay 

 and Macleay stated definitely that this figure, which they call "a very bad one", does not 

 represent the Port Jackson Shark. In Lesson's figure the color pattern of the body is 

 unHke that of any other drawing of Heterodontus ph-illipi known to me, and the shape of the 

 ventral lobe of the caudal fin is unHke that shov.Ti in all other drawings of specimens 

 belonging to the genus Heterodontus. It is not necessary to reproduce this figure, since it 

 ■w.^s e\'idently drav.Ti from a dried and distorted specimen. 



Miiller and Henle's full'length colored portrait (1841, pi. 31) labelled Cestracion 

 philUpi is reproduced, under its proper name, as my Text-figure 21, page 690. In 1879 

 Macleay expressed a doubt as to the identity of the species represented by this figure, and 

 in particular stated that the form of the six-cusped tooth pictured by Miiller and Henle 

 (but omitted from my Text-figure 21) had never, they beHeved, been seen in any adult 

 specimen of the Port Jackson Shark. Further, in 1884, Maclay and Macleay stated that 

 Miiller and Henle's figure is most likely of the Japanese species, the number of vertical 

 bands being identical, and that the tooth portrayed in the same plate is certainly not of 

 either species. x'\t the present time one can scarcely doubt that Miiller and Henle's 

 figure of the entire fish is a fairly accurate representation of the Japanese Bullhead 

 Shark, Heterodontus japonicus. The same may be said of Brevoort's drawing (1856) of 

 a specimen collected by the Perry Expedition to Japan. This specimen was labelled 

 Cestracion phillippi; it is reproduced, under its proper name, as Te.xt-figure 22, page 690. 



Striiver (1864) has contributed what appears to be an accurate drawing of a badly 

 posed specimen of Heterodontus philUpi. Perhaps this fish had been hardened in a laterally 



Text-figure 6. 

 A full-grown male specimen of the Port Jackson Shark, Heterodontus philUpi, 795 mm. (31.4 inches) 

 long. The external opening of the spiracle (retouched to make it more clearly visible) is shown behind, 



and a little below, the eye.
