23a. C. carcharias. White Shark. Sqitalus carcharias Linne, Syst. Nat. 10th ed., 1758, 

 p. 235 ; C. carcharias Garman, Mem. Mus. Comp. Zool. xx.xvi., 1913, p. 32, pi. 5, 5-9. (PI. xvii.). 



A fierce and destructive species which attains a length of forty feet. It ranges over all warm and 

 temperate seas, and has been recorded on several occasions from our waters. Fossil teeth of a closely 

 allied species indicate that a very recently extinct relative of this shark must have reached at least 

 eighty feet in length. 



XIV. Family Cetorhixidae. 



24. Cetorhinus Blainville, Bull. Soc. Philom. viii., 1816, p. 121 (gunneri). 



24a. C. maximl'S. Basking Shark. Sqitalus maximus Gunner, Trondhj. Selskab. hi., 1765, 

 p. 33 ; Selache maxima Day, Fish. Gt. Brit. & Ireld., ii., 18S0-1884, p. 303, pi. 158, 1. (PI. xvii.). 



A very large, but harmless shark, attaining a length of 35 feet. It occurs in all warm and tempe- 

 rate seas, but has only once been noted in our waters. Its food consists of minute floating animals, 

 which are apparently strained from the water by means of peculiar comb-like structures on the gill- 

 arches. 



XV. Family Squalldae. 



25. Squalus Linne, Syst. Nat. 10th ed., 1758, p. 233 (acanthias). 



25a. S. megalops. Piked Dog-fish. Acanthias megalops Macleay, P.L.S. N.S.W., vi., 1881, 

 p. 367. (PI. xvii.). 



Abundant in somewhat deeper waters, w-here it is taken by the trawlers. Grows to nearly three 

 feet in length. Though this shark is disdained as food, quantities of an allied species are imported into 

 Australia in a smoked condition, and sold as " Smoked Haddock."
