The Inzards of Kansas 71 
inches at the western boundary. The northern half re- 
ceives practically the same amount of rainfall as the 
southern. The eastern part of the state thus presents a 
much more humid surface soil than the western part of 
the state, another factor that has a profound influence 
upon lizard dispersal. 
Only three of the fourteen established species of Kan- 
sas lizards have a state wide distribution. Cnemido- 
phorus sealineatus is one of the most widely distributed 
lizards in both the United States and Kansas. It is com- 
mon to both eastern and central faunal lists. Phrynosoma 
cornutum and E'umeces obsoletus are also state wide in 
their distribution, but have come from the southwest be- 
yond the plains of Kansas. Hurter (1911) reported only 
P. cornutum from Missouri, and Hurter and Strecker 
(1909) reported neither species from Arkansas. 
Crotaphytus collaris occurs both to the east and to the 
west of Kansas. Its center of distribution is decidedly 
in the west, California being on the western line of its 
dispersal and Missouri on the eastern. Its distribution 
in Kansas is peculiar since it has been reported from 
only the eastern two-thirds of the state. 
The skinks, Eumeces septentrionalis and E. multivir- 
gatus, have their center of distribution in the ‘‘central 
area’’ and do not occur far to the east or west of Kansas. 
The former is a north central form, and the latter a 
south central form, Kansas lying in the pathway of the 
distribution of each, and possibly being the southern 
boundary of the range of E. septentrionalis, since Orten- 
burger (1926 a-b-e) did not report it from Oklahoma. 
€ nine species of lizards that are left, counting again 
Ewmeces obsoletus, which has not been found east of 
Kansas, fall into two nearly equal groups and are listed
