The Inzards of Kansas 43 
these race-runners going in and out of gopher tortoise 
burrows in Florida. Dr. Edward H. Taylor of Kansas 
University in a recent interview stated that while he was 
collecting in Tennessee during the summer of 1926 he 
found C. sexlineatus occuring abundantly in a heavily 
forested region on a bank of the Tennessee River, over 
which rose a hill that was covered with limestone ledges. 
The writer has often collected this lizard. It frequents 
a greater variety of habitats than all other Kansas spe- 
cies, and it seems that only a high moisture content of 
the surface soil restricts its distribution, since it has 
often been collected from rocky ledges and sandy areas, 
but only rarely from loamy situations. It has been found 
on rocky hillsides, open corn and wheat fields, upland 
meadows, low sandy river banks, about chalk cliffs, rail- 
road embankments, road beds, sand dunes, isolated sand 
banks, occasional out-croppings of rock, and on the up- 
per part of wooded hillsides. These creatures are often 
found close to dwellings, and are apparently able to 
adapt themselves to changes brought about by agricul- 
tural conditions. 
These race-runners are probably the swiftest of Kan- 
sas lizards. Taylor (unpublished) found them to be very 
common in the chalk cliffs of Trego and Gove counties, 
but obtained only a small number because of their great 
agility. No doubt the swiftness of this lizard in escaping 
its numerous enemies, including man, is responsible in 
a large measure for its ability to survive even in the 
more populated districts. : 
In regions where there are no rocks for hiding, mem- 
bers of this species dig holes in which they stay at night. - 
These holes are probably used repeatedly, and often 
when a specimen is disturbed in the day time it runs 
rapidly away, and finally ees into one of them. ae
