The Inzards of Kansas 37 
regeneration, using as a basis of calculation the second- 
ary length, was 32.35 per cent of that length. 
Measurements taken on the 32 Kansas specimens of 
this lizard, mentioned above, are as follows: Length of 
body, 56-250 ( 201-250) ; length of tail, 248-438 (301-360) ; 
total length, 294-655 (501-600); width of head, 4.5-16 
(10-12) ; length of tail as percentage of total length, 62.5- 
69.1 (68-69) ; width of head as percentage of body length, 
3.0-7.0 (4.0-6.0). 
The length attained by this species is in excess of that 
of all other Kansas lizards. Also, the width of head 
as percentage of body length is less than that of other 
species. Hay (1892) gave the total length of the largest 
Specimen which he had measured as 915 mm., a figure 
greatly in excess of the largest one examined by the 
writer. Hurter (1911) found the total length to be 
702 mm., tail 455 mm., and body 247 mm. Taylor (un- 
published) measured a large Kansas specimen which has 
since been lost. His measurements were, total length, 700 
mm., tail 456 mm., and body 244 mm. 
Habitat and Habits—This widely distributed lizard 
has often been collected. Holbrook (1842) stated that 
“‘This species chooses dry places for its abode, and 
passes much of its time in holes, or under the roots of 
old trees, and is often dug out of the earth with the 
Sweet potato at harvest time.’? Hay (1892) wrote that 
‘This animal selects for its abode, dry, rather than damp 
situations.” Ditmars (1910), during several collect- 
ing trips in the south noted a condition pointing toward 
the noctural habits of the species. ‘‘There was a scarcity 
of specimens abroad during the day, but in the early 7 
morning, however, they were found in wells, where they 
had evidently tumbled during their nightly search for . . 7 
food,’? Taylor Nps tematic stated that ‘‘One speci- -
