broad black borders. Some black ou the postoculars and loreal. 

 The last two or three inferior labials maculated with black. 



There are three color varieties of this species. Two of these 

 varieties are represented in Kansas. In one the ground color 

 is so dark that the spots are obscured ; in the other the ground 

 color is light and the spots are very distinct. 



Head distinct from body. Body thick. Tail from one-fourth 

 to two-ninths of the total length. This is the largest Garter 

 Snake in Kansas. One now in this laboratory is thirty-four 

 inches in length. It is slow in its movements and seldom at- 

 tempts to bite. 



It has a wider distribution and occurs in greater numbers 

 than any other Kansas Garter Snake. I have examined speci- 

 mens from Geary, Lj'on, Douglas, Franklin, Mitchell, Clay, 

 Republic, Ellis, Rawlins, Wallace, Scott, Logan, Gove and 

 Riley counties.

Onl}' one variety of elegans occurs in Kansas. Cope ( 10. 

 1034)* gives eight varieties as occurring in North America. 

 Brown (5.22) gives five varieties. His key to the subspecies 

 is as follows : 



a. — Post-oral crescent absent: 



Color dark; spots and lateral stripes often indistinct. 



J'J. elegans elegans. 

 Color lighter: spots encroaching on stripes.. . E. elegans vagrans. 

 Often 2 preoculars and 23 rows; otherwise like vagrans. 



E. elegans bisfiilaiu. 

 b. — Post-oral crescent present: 



Spots and stripes distinct E. elegans marclana. 



Spots and stripes indistinct or absent E. elegans couchi.
