ALOPIAS. Generic Characters. Head, dorsal and anal fins, and spiracles, 

 as in the genus Lamna ; upper lobe of the tail very long, with a depression at 

 the base. Teeth triangular, flat, with smooth cutting edges in both jaws, curv- 

 ing outwards on each side from the centre. Branchial openings small, the last 

 over the pectoral fin. 



THIS species is occasionally met with on the British coast : 

 Pennant examined one that measured thirteen feet in length ; 

 and specimens have been seen of fifteen feet long. It is 

 called the Sea-Fox from the length and size of its tail ; and, 

 according to Dr. Borlase, has received the name of Thresher 

 from its habit of attacking other animals, or defending itself, 

 by blows of the tail.* It is an inhabitant of the Mediterra- 

 nean as well as other seas ; and a specimen has been taken 

 near Belfast.
