 quently they are seldom seen there.

None of these fishes are used as food in Tasmania, 

 although the Dog Fishes are very abundant. Certain of 

 them (Galeus cams) are captured, and the livers boiled 

 down for oil. The fins of this shark are also exported for 

 the preparation of isinglass. It is affirmed by the fishermen 

 that the use of deep-sea lines would be valueless here on 

 account of the vast number of destructive Sharks. 



TORPEDINID^. 



There are four members of this group known in Tasma- 

 nian vraters, which include the Electric Torpedo, the Thorn 

 Back, and the Stingai-ee. They are not of any value, 

 however, and may be ignored.
