prevent its being distinguished by the natives of that locality from 

 the deadly moccasin, with which they almost invariably confound it. 

 The original spelling of the specific name for this species, cyclopion, 

 should be adhered to. 



Specimens: Samburg, 3 ad.; 1 juv. 



17. Natrix leberis (L.). Seven-striped Water Snake. 



Not seen except in the central basin. In a large specimen from 

 Bellevue there are no black dorsal stripes. The back is uniform 

 olive brown with a pale whitish stripe along margins of outer dorsal 

 scutes, succeeded by a blackish stripe on edges of abdominal scutes 

 which is distinct from the next yellow stripe anteriorly, but is 

 merged ventrally with the inner black stripe of belly. The median, 

 yellow, inferior stripe disappears on the abdomen, and wholly fades 

 in the black of the ventral and caudal regions. This results in the 

 diminution of the pectoral pattern of five light and four dark stripes 

 to an abdominal striation of two obscure light lateral lines, and an 

 unbroken intervening dark area formed by the confluence of the 

 seven light and dark median stripes of the pectoral region into a 

 single band of black. Two young, taken with this specimen, 

 show faint vertebral and costal stripes, and in all other respects 

 are normal. The above description seems to show an approach to 

 grahami, but its nineteen dorsal scale rows and color pattern are 

 nearer leberis. Its peculiarities lend some color to the idea that 

 grahami is not specifically separable from leberis, and Prof. Cope's 

 diagnosis of the two (Proc. Nat. Mus., XIV, p. 667) shows, when 

 compared with that of Prof. Garman (Rept. & Amphib. Ills., p. 

 272), that their characters are quite variable, and this, too, in the 

 direction of each other." 



Specimens — Bellevue, 1 ad., 2 juv. ; Richland Creek near Nash- 

 ville, 1 juv. 



Genus OPHEODRYS Fitzinger. 



18. Opheodrys aestivus (L.). Green Summer Snake. 



Reported from all over the State, but only seen by me on the 

 Cumberland plateau in Scott and Fentress counties. It is probable 

 most of the "Green Snakes" of east Tennessee are Liopeltis 

 vernalis (De Kay-Harl.), none of which were taken. 



Specimens — 3 m. W. Rugby Road, Scott County, 1 juv.; 8 m. E. 

 Allardt, 1 ad.
