The Inzards of Kansas 13 
A summary of the data follows. Length of body, 20-61 
(45-60) ; length of tail, 17-76 (36-45) ; total length, 38-132 
(91-100) ; width of head, 4.5-11 (8-9); length of tail as 
percentage of total length, 39.9-58.3 (44-46); width of 
head as percentage of body length, 13.0-22.9 (18-20). 
In his key to the species of Holbrookia, Schmidt (1921, 
1922) separated H. maculata maculata from other liz- 
ards of the genus by the character, ‘‘Tail shorter than 
body in the female, usually also in the male.’’ To test 
this distinction, 32 specimens, males and females in 
equal numbers, were selected and measured. The results, 
expressed in terms of length of tail as percentage of 
total length, are as follows: 
Males: Range, 44.0 to 58.3 per cent; average, 49.0 per 
cent. 
Females: Range, 41.0 to 49.3 per cent; average, 45.0 
per cent. 
This indicates that Schmidt’s distinction holds uni- 
versally for the females, but does not do so for the males. 
Twenty-nine or 18.5 per cent of the 175 specimens cited 
in the measurement table above had a tail length of over 
50.0 per cent. Granting that they are all males, the prob- 
ability of error (as indicated by this series) in the iden- 
tification of a male of H. maculata maculata by Schmidt’s 
key would be approximately 37.0 per cent. 
All of the measurement figures given by other writers 
for this species fall, so far as known, within the ranges 
designated in this work. 
There has been considerable question as to the possible 
presence of H. maculata lacerata in Kansas. Cope (1900, 
p- 293) reported it from Neosho Falls, Woodson County, 
on the basis of three specimens (No. 4693) in the collec- 
tion of the United States National Museum. The exam- 
ination of over 200 specimens of H. maculata from Kan-
