154 BEAUMARIS SHARK. Class IV. 



[The Porbeagle Shark, so well described by 

 Doctor Goodenough, Bishop of Carlisle, in the 

 third volume of the Linncean Transactions, dif- 

 fered only in some trifling circumstances from 

 the above. Its color was of a deep blue ; the 

 punctures extended from the nose to the nostrils ; 

 in the mouth were only two rows of teeth, in the 

 upper jaw, except in the front, where the two 

 middle ones stood single ; in the under jaw were 

 also two rows, except in the front, where the 

 two middle teeth had a triple row. As the 

 number of teeth, however, seems to depend upon 

 age, no specific distinction can be drawn from 

 them. The subject described by the learned 

 Prelate measured three feet ten inches from the 

 tip of the nose to the extremity of the tail ; he 

 was informed that they sometimes grow to the 

 length of eight feet, and when of a large size have 

 a triple row of teeth. Ed.
