AMPHIBIA AND REPTILIA OF COLORADO 1 23 



Kansas has much the same snake fauna and Utah the same lizard 

 fauna as Colorado, both of these states having, however, many- 

 additional species of these two groups not found in Colorado. 



Tables 5, 6, 7 and 8 give the data collected on the altitudinal dis- 

 tribution of our species. The amphibians (Table 5) seem the least 

 influenced by altitude of any of the groups. Seven of the eleven 

 species have been taken above the 6,000-foot contour line. The 

 7,000-foot contour is passed by but five of the snakes and five of the 

 lizards, and it is not reached by any of the turtles. Three species, 

 a snake, Thamnophis elegans, a toad, Bufo boreas, and the salamander 

 Amby stoma tigrinum have been taken above the 10,000-foot contour.
