The Lizards of Kansas 7 
occasionally with a pattern of alternate white and gray 
transverse bars, giving a ‘‘tiger design’’; upper head 
scales usually green or brownish olive with the colora- 
tion becoming more intense as the median line is ap- 
proached. 
Double black collar on shoulders, not extending ven- 
trally in Kansas specimens; both bars of collar usually 
broken dorsally; back and tail of same general colora- 
tion; tail much more blotched and sometimes with ringed 
appearance; color duller in young than in adults; large 
males sometimes with highly colored gular region of 
orange or yellow and much of the rest of the body blue 
or green; other males and always females, duller. 
During the fall of 1925 the writer collected, and ob- 
served the coloration upon, over forty young specimens, 
all of which showed the dull coloration characteristic of 
the female. The colors of all forms are deeper after the 
skin is shed, and those of the adults, also, at the spring of 
the year during the mating season. 
In 275 specimens from Kansas the number and ar- 
rangement of the scales between the orbital areas has 
been found to be as follows: specimens with two distinct 
rows, 28 or 10.2 per cent; specimens with two of these 
paired scales fused to one single scute, 115 or 41.9 per- 
cent; specimens with four fused to two singles, 121 or 
44.0 per cent; specimens with six fused to three singles, 
10 or 3.6 per cent; and specimens with eight fused to 
four singles, 1 or 0.3 per cent. This indicates that the 
interorbital scutellation of Kansas individuals presents, 
essentially, a condition of two rows, excepting for a few 
fused scales which make a single row for a short dis- 
tance. 
A summary of the study of 300 Kansas specimens is 
given below. Measurements are given in millimeters,
