THE SNAKES 311 



But two species of Elaps occur in the United States. 

 Their red, yellow and black-ringed coloration causing 

 them to look rather alike. There is also a strong resem- 

 blance to several harmless snakes, particularly the follow- 

 ing species: Arizona King Snake, Ophibolus zonatus; 

 Western Milk Snake, O. doliatus gentilis; Scarlet King 

 Snake, O. doliatus and the Scarlet Snake, Cemophora 

 coccinea. Careful examination will demonstrate a val-

 It will be noted in the case of the poisonous snake that 

 the black rings are single and bordered with a pair of 

 yellow rings. With the harmless species the yellow 

 rings are single and bordered with a pair of black rings. 



The species of Coral Snakes found in the United 

 States may be easily separated, as follows: — 



Snout black; a yellow band across the head, followed by a black ring. 

 Haelequin Snake; Coral Snake, Elaps fulvius. 



Habitat: Southeastern United States into Mexico. 

 Snout black ; a yellow band across head, followed by a red ring. Sonoban 

 Coral Snake, Elaps euryxanthus. 



Habitat: Arizona and northern Mexico.

 Specimens are found wandering about, after heavy rains.

 tern consists of regularly-disposed, broad scarlet and 

 black rings, separated by narrow rings of yellow. The 

 snout is black ; a wide orange band crosses the head. It 

 is not unusual to find specimens with the scarlet much

 the coloration is more brilliant. A big example is a yard 

 long and three-quarters of an inch in diameter at the
