OF NEW SOUTH M'ALES. . 313 



This Shark is frequently caught in Port Jackson, and seems 

 to have been found from time to time on various parts of the 

 Australian and New Zealand coasts. It is also stated to have 

 been found in the East Indian Archipelago and Japan ; but there 

 seems to be some reason to suspect the identity of the Japanese 

 species, if not of the other. Certainly, the figures given as 

 those of the Port Jackson Shark, in the Voy. of the Coquille, pi, 

 11, and in MuUer and Henle, pi. 31, are so extremely unlike the 

 fish they are intended to represent, as to suggest a doubt of their 

 being the same species ; and the form of the penta-cuspid tooth, 

 figured by the last-named authors, has never, we believe, been 

 seen in any of the Port Jackson adult specimens. The numerous 

 transverse bands on the back, too, in those figures, suggestive of 

 the specific name " zebra," are utterly unknown in the true H, 

 Phillipi. 



But little can be added to the history of this curious Shark. 

 The stomach is generally well filled with fragments of shells, but 

 not so finely comminuted as might be expected from the charac- 

 ter of the teeth, and the bowels are often well charged with 

 cestode worms. It is remarkably tenacious of life, but if we are 

 to believe the accounts of the fishermen, very slow of reproduc- 

 tion — never having more than two eggs at a time, and only one 

 brood in the year.

This species has a less elongate appearance that H. Phillipif 

 but I cannot find an appreciable difference in the proportionate 

 measurements. I shall confine my descriptions to those points 

 only in which it differs from that species already so elaborately 

 described. 



The head is more rounded in profile. The upper lip has the 

 lateral flap less developed, not overlapping so much the lateral 

 fold of the lower lip. The jaws shorter and deeper, the hinder 

 part of the " rami " of the lower jaw being very deep. The 

 teeth are similar as to number and distribution, but very 

 difiierent in form, the smaller teeth towards the symphysis of the
