 Abdominal scuta 150, subcaudal 40. 



A SMALL species, seldom exceeding the length 

 of about fifteen inches : head large, with the 

 cheeks swelling out like those of vipers ; the nose 

 turning up, like that of a hog : body very thick 

 towards the head : colour pale brown, with several 

 large black spots or patches disposed along the 

 back and sides : towards the lower part of the 

 back the spots form a kind of black bars over that 

 part, the ground-colour between them being yel- 

 lowish : the abdomen is of a dusky white with 

 small blackish spots. This species is a native of 

 North America, and is of a poisonous nature : it 

 is slow in its motions, and has a malevolent as- 

 pect : the tail is nearly a third of the length of the 

 whole animal.
