We have only seen one specimen of this species of shark ; but others were taken in the Cape 

 Seas during our residence in South Africa. It swims close to the surface of the sea, and is said 

 to be very active, and to feed upon fishes which it captures by its speed. The one we examined 

 had the stomach distended with portions of Acanthias australis, Smith, Callorynchus australis, 

 Cuv., and a species of Loligo.
