The Lizards of Kansas 27 
specimen from Bloomington, Indiana, kindly sent to the 
writer by Mr. G. 8. Myers, now at the Leland Stan- 
ford University, has been identified by Miss Doris M. 
Cochran of the United States Museum as this subspecies, 
and Blanchard (1925) reported it from Twin Caves, 
Indiana, the State of Indiana as a northern point in the 
known range is established. 
The distribution of this subspecies in Kansas is prob- 
ably confined to the eastern edge. A comparison of 
figures, 3 and 4, will show that in Kansas the distribu- 
tion of S. undulatus undulatus is entirely distinct from 
that of S. undulatus thayerti, and that a space of several 
counties in which much collecting has been done, sepa- 
rates the known range of the two forms in the state. 
Phrynosoma cornutum (Harlan).
