specimens Avere collected in shallow forms under stones and sheets 

 of tin. The writer found individuals in a like environment and in 

 the same i>cneral situation at a couiiti y dump near Haddam, Wash- 

 ington County, Kans., in June, ID'JS. 



In Tennessee "They are common in sandy situations and are 

 always found on the around'' (Blanchard, 11)22, p. 6), and in Ken- 

 tucky they are usually found '' in open country, along sandy banks, 

 or in plowed fields." (Funkhouser, 1925, p. 78.) 



In Kansas " It has been seen in the sand dunes along the Kansas 

 Eiver (Riley County), and has been taken in small numbers under 

 flat, hilltop rocks." (Burt, 192T, p. 4.) The same author in his 

 "Lizards of Kansas" (1928) wrote as follows: "The writer has 

 often collected this lizard. It frequents a greater variety of habitats 

 than all of the other Kansas species, 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, in upland meadows, on low 

 sandy river banks, about chalk cliffs, railroad embankments, road- 

 beds, sand dunes, isolated sand banks, occasional outcroppings of 

 rock, and on the upper part of wooded hillsides. These creatures 

 are often found close to dwellings, and are apparently able to adapt 

 themselves to changes brought about by agricultural conditions. 



" The 6-lined race runner is perhaps the most gregarious of all 

 Kansas lizards. Specimens were nearly always found at certain 

 places, even though the collector returned again and again, Avhereas, 

 at points not far away, which looked equally attractive as a habitat, 

 none were seen." 



This lizard is an inhabitant of the lower levels onl}^ and does not 

 occur far up in either the Rockies or Appalachians. 



General hehavior. — In the vicinity of Fort ]\Iacon, N. C, " these 

 lizards appear early in April," as stated by Cones (1871, p. 47), 

 " and may be found until cold weather in October." They spend the 

 winter in hibernation in some protected niche and Kansas specimens 

 disclosed early in the spring are inactive and often covered by a 

 damp, black coating of earth, which wears off after a few days of 

 activity. 



Although Holbrook (1836, p. 65) found that sexlineahis "gener- 

 ally seeks its food toward the close of the day, when it may be seen 

 in cornfields far from its usual retreat," the writer has found that 

 Kansas specimens become active in the early morning, and continue 

 their activity until aljout noon. In the afternoon fewer specimens 

 are seen, and at evening most of the specimens seem to have retired 

 to their burrows to spend the night. The race runner is apparently 

 entirely diurnal in its luibits. " Over night some at least remain in
