and somewhat tuberculate in large specimens; ventrals 
decidedly larger; enlarged post-anal plates present in 
males only. 
Coloration not highly variable; ventral parts immacu- 
late white, with or without a ‘‘tiger design’’ of slate col- 
ored bars on the chin; dorsal ground color ashy gray, 
with two rows of dark blotches extending from the re- 
gion posterior to the head to well upon the tail, varying 
in series, anterior to posterior, from ten to fourteen in 
number; median line distinct and free from blotches; a 
row of lateral blotches on each side, usually not sharply 
defined, but distinctly visible; subcaudal black spots 
never present; from two to four black latero-ventral bars 
on each side of abdomen; lateral aspect of the belly 
sometimes bluish; otherwise, the ground color of the 
sides varies from light yellowish through different 
shades of orange to dull reddish. 
By the examination of 148 specimens of H. maculata 
maculata from Kansas, it was found that the black bars 
on the right side numbered from two to four units, as 
follows: with two bars, 104 specimens; with three bars, 
38 specimens; with four bars, six specimens. There is 
sometimes the same number of bars on each side of this 
lizard, two being the most common, but frequently there 
is a variation, three on one side and two on the other oc- 
curring most often. Schmidt (1922) found in a series of 
nineteen females from Colorado that ten had two spots 
on each side, four had two spots on one side and three on 
the other, five had three spots on each side, and one had 
three on one side and four on the other. 
In order to study the variation in size and proportion 
of this lizard 175 Kansas specimens have been measured. 
Unfortunately the writer failed to sex a large proportion 
of them, so sexual dimorphism cannot be fully treated.
