Abstract

The Leopard frog (Rana halecina, Kahn) and allied species occur in considerable numbers and have a wide geographical distribution. Being entirely defenseless, beset by enemies at every turn-fish, reptiles, birds and mammals-as well as being cannibals among themselves, subject to many diseases and the hardships of great extremes of temperature, they are, withal, able to maintain their numbers.
