THE RIBBON SNAKE 

 Eutcenia saurita, (Linn.) 



The species is one of the most slender of the American ser- 

 pents. It is of moderate size. The scales are strongly keeled, 

 thus imparting a velvety aspect to the upper surface. With 

 most specimens, the tail constitutes a third or more of the. total 

 length. 



Colouration. Rich, dark brown or black above, with a vivid 

 yellow stripe extending down the back, and a similar stripe on 

 each side, the latter covering the third and fourth rows of scales 

 above the abdominal plates. With brown specimens, the stripes 

 are narrowly bordered with black. The stripe on the back is 

 very sharply delineated and produces a ribbon-like aspect 

 hence the popular name.
