Jones (1926) has shown that S. thayerii is the proper 
name for S. consobrinus, but has not made clear just 
what should be done about the subspecific classification 
of the lizard. 
Description—Head somewhat narrowed and de- 
pressed; superciliary ridge slight; tympanum exposed; 
a well-marked fold of skin on each side of neck, making 
a characteristic groove; gular region without a fold; 
body moderately slender; tail tapering gradually to a 
point; head plates large and smooth; supraoculars 
bounded on each side by small scales; occipital plate 
large and very prominent; dorsal scales very strongly 
keeled and with strong posterior spines; scales of lower 
sides and abdomen smooth and without keels; femoral 
pores present; enlarged post-anal plates in males only. 
Coloration varied; dorsal ground color light to dark 
brown; abdomen whitish; sides often brilliant blue; usu- 
ally with two well defined stripes of clear yellow on each 
side; a series of dark brown lateral spots, which never 
connect to form undulating lines, usually present above 
and below the upper longitudinal stripes. 
In order to study the variation in size and proportion 
of this lizard 108 Kansas specimens were measured. The 
data are as follows: Length of body, 21-62 (49-56); 
length of tail, 24-81 (61-70); total length, 45-140 (111- 
120) ; width of head, 5-12 (8-9) ; length of tail as percent- 
age of total length, 48.3-61.1 (56-58); width of -head as 
percentage of body length, 13.5-24.1 (16-18). —
