Hurler — Herpetology of Missouri. 181 



Habitat. — From Virginia south to Florida, west to 

 Texas, north to Missouri. Missouri localities : — St. Louis 

 and Montgomery Counties. 



Habits. — I have found the Chicken Snake quite scarce 

 in Missouri. My friend, Mr. E. M. Parker, presented me 

 with a fine half grown specimen from Montgomery Co. 

 Ditmars says "All the Colubers show a great fondness for 

 eggs and swallow them entire, but as the eggs pass about 

 fourteen inches down the reptile's neck, that portion of 

 the body is pressed against the ground and by a strong 

 steady contraction of the swallowing muscles, the shell 

 of each egg is broken and the fragments are swallowed 

 together with the contents of the eggs and are digested. ' ' 

 My own observations do not agree with this. Whenever 

 I found a snake that had swallowed an egg I always found 

 the egg entire in the stomach, where the shell had been 

 softened by the gastric juice. Chicken Snakes feed on 

 rabbits, rats, mice, birds, young chickens, and eggs. Like 

 many other snakes this one emits a very offensive secre- 

 tion from glands at the end of the tail when overpowered. 

 This secretion is white and viscid. The species is ovi- 

 parous.
