Rana catesbeiana SHaAw—The bullfrog is not common and is 
lways associated with water. Specimens have been collected at 
examined contained crayfish and one revealed the remains of a 
mouse. 
Rana clamitans LATREILLE—The green frog is most frequently 
found in backwaters or isolated pools into which an abundance 
of leaves have fallen. They have been taken at Danby, Wolf Hollow 
Spring, Moss Hollow Spring, and Isle Du Bois Creek. The species 
seldom ventures far from the water and examples are often found 
crouching beneath some shelter during the day. A water snake, 
Natrix stpedon sipedon, disgorged a young green frog at capture; 
and another green frog was eee hag under a rock where a cray- 
fish had been feeding upon it. is possible that the crustacean 
killed the frog. A collection au July 24, 1932,.showed an equal 
representation of both sexes. 
Rana palustris Le Conte—The pickerel frog is rare in this 
county. A few specimens have been taken at Moss Hollow Spring. 
Elsewhere in Missouri they have been taken most frequently in

in thickets when alarmed.

strawberry patch about 500 feet from the nearest water. The 
animal, crouched in the steamy, hot location when discovered, and 
hopped into the weeds when disturbed. The only explanation of 
its presence in so unfavorable a location was that of the abundance 
of insect life here at night.
