ALOPECIAS. 



This is a genus established by Miiller and Henle, and described as 

 with, a pointed, conic head, very small spiracles, small gill openings, 

 and simple triangular teeth, but particularly marked by a very great 

 extension of the tail. It is the genus Alo2}ias of Ratines que and 

 Swainson; but the latter writers had overlooked the very small spiracles.

 and Romans, who were well acquainted with the fish, were not 

 content with finding in it nothing more than this likeness of 

 analogy; and therefore they went on to draw the conclusion 

 that a fish answering to this name must of necessity be endowed 

 with the other distinguishing portions of the foxine character. 



This fish is not recognised in the tenth edition of the System 

 of Linneeus, but it is the Squalus vulpes of Turton's Linnaeus. 



The Thrasher, or Sea Fox, is so very rarely taken on a line, 

 that no instance of it has come within my knowledge; but the 

 reason of this probably amounts to no more than that fishermen 

 do not employ the bait that tempts its appetite. jElian, how-
