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.
