Fig. 15 Natrix leberis 



Above chestnut brown, with a lateral yellow band, and three 

 narrow black dorsal stripes ; abdomen yellowish, with four brown 

 longitudinal bands. 

 Length 2i inches. 



From description 

 only, this species 

 might possibly be 

 confused with E u - 

 taenia saurita, 

 which is also 

 striped longitudin- 

 ally, though with 

 differently arranged 

 colors. Both spe- 

 cies are highly aquatic in habit. 



Natrix leberis, though included in many f aunal lists, seems 

 to be scarce throughout our region, as nearly every observer states 

 that he has never met it, himself, but includes it on good authority. 



Cope (1900, p. 995) notes a specimen (no. 10,729) in the U. S. 

 national museum from Livingston county, N. Y. 



15 Natrix kirtlandii (Ivennicott) 

 Kirtlan cVs sn alee 

 Jordan. Clonophis kirtlandi 

 Head very small ; not distinct from body. Scales very strongly 

 keeled, in 19 rows. 



Above, light red- 

 dish to purplish 

 brown, with four rows 

 of large darker 

 blotches on back and 

 sides ; beneath, pale 

 brick red, with black 

 spots. Length 16 

 inches. 



Recorded by Ab- Fig. 16 Natrix kirtlandii 



bott ('6S) from New Jersey, but the identification apparently 

 doubted by Nelson ('90). Cope (1900, p. 997) restricts its range to 

 Wisconsin, Michigan, Illinois, Indiana and Ohio.
