then stopped up by the female with closely packed earth, 
and the young must dig their way out after hatching.’’ 
A Riley County specimen which the writer opened con- 
tained seven eggs. Another which was transported to 
Cheboygan County, Michigan, early in the summer of 
1927 laid two eggs on June 26, one on July 1, two more on 
July 2, and finally four others on July 4, a total of nine 
eggs in nine days. 
The food of Crotaphytus collaris consists, chiefly, of 
the larger insects, particularly grasshoppers and 
crickets. 
Distribution im Kansas—Kansas_ specimens that 
might be identified as the “‘bailey:’’ type have always 
been found in co-extensive distribution with the ‘‘col- 
laris’’ type. The collared lizard has been taken in the 
eastern two-thirds of the state only. It has generally 
been found about rocky formations which cover a con- 
siderable area, and has usually been absent from small 
outcroppings of rock. This, together with the fact that 
it has not been collected in large cultivated areas, such as 
are found in Rice, Barton and Brown counties, would 
tend to indicate that it is not a species highly resistant to 
the encroachments of man upon nature, and as agricul- 
tural methods become more intensive and more ground 
is tilled in Kansas the area of its distribution will prob- 
ably be constantly decreased. Although the collared 
lizard is said, by various writers, to be a desert form, 
the author has not found it in the drier situations of 
Kansas, even though rocks were there in abundance. It 
is usually found where there is considerable moisture, 
typically at the upper edge or above the woods which are 
found near streams, and the dry condition which is pre- 
sented by the climatic cycle of western Kansas may help
