Storeria occtpito-maculata (Storer)—Red-bellied Snake.— 
This snake is occasionally seen in the county. A specimen was 
taken at Lake Okoboji, June 20, 1917, by Dr. T. C. Stephens. 
Thamnophis sirtalis parietalis Say —Red-sided Garter Snake. 
—Common, but much less so than 7. radix. Eight specimens, 
representing the townships of Lakeville, Okoboji, Center Grove, 
and Spirit Lake, were secured and these were all found not far 
from woods. 
Thamnophis radix (Baird and Girard).—Common Garter 
Snake.—This is the common land reptile of the region. It was 
found in all the townships and in all habitats visited. It was, 
however, only rarely met with in the woods, but on the prairie 
in tall or short grass, along fences and roadsides, near marshes, 
sloughs, and lake shores, it is frequently seen. It will readily 
take to water when disturbed along the shore of a pond, and 
one young individual was met with at least a hundred feet from 
the shore of Miller’s Bay, swimming toward the open lake. 
Chelydra serpentina (Linné). Snapping Turtle—Common in 
all the lakes, sloughs, and rivers in the region. Specimens ob- 
tained represent Lakeville, Center Grove, and Spirit Lake Town- 
ships. A nest containing nineteen eggs was found near the 
lake shore in the field north of the Laboratory on July 1, by 
Professor F. A. Stromsten. The nest had been opened by some 
animal and two or three eggs taken out and destroyed. It was 
very fresh, perhaps not more than a day old. A specimen found 
killed on the shore of Hottes Lake had a carapace 38 centimeters 
long. 
Emys blandingvi (Holbrook).—A large female of this species 
was captured in a bayou of the Little Sioux River directly west 
of the town of Spirit Lake, and was given by Mr. Frank P. Hop-
