Zoology.'] NATURAL HISTORY OF VICTORIA. [Fishes. 



the years the vote appeared on the Estimates for the destruction 

 of Sharks on our shores — this httle hkmt-toothed creature lieing 

 accepted as the young of the gigantic AVhite and Shovel-nosed 

 Sharks, whose sharp teeth made havoc with fish, nets and men. 

 There were no figures of our fishes to guide the well-intentioned 

 blunderers at the time. It is much less prolific than the Picked 

 Dog-fish, and the viviparous young have no placenta. 



As usual in the genus, there is a small ridge from l)eliind the 

 head to the 2nd dorsal, and in this species continued thence to the 

 caudal, and a smaller ridge from the anal to the caudal fin ; there 

 is no pit at hase of caudal. 



This fish is here fis-ured of its natural colors for the first time. 



Common in Hobson's Bay.
