The Leopard or Shad Frog is usually found in wet places in marshes 
and upon the borders of streams, though it is said to have been found in 
summer in fields at a distance from water. They are active animals, 
very difficult to capture, leaping from eight to ten feet, emit a peeping 
note, and lay their eggs in April. This is the analogue, and it may be 
a variety of the Huropean Rana esculenta, or Green Frog, which it resem- 
bles.

The habits of this little animal are very similar to those of Rana 
halecina, and there is considerable doubt in my mind whether it should be 
retained as a distinct species, and not considered a variety of young Rana 
halecina ; while the typical halecina differs strikingly from the typical pa- 
lustris, the varieties of these closely approach, if they do not shade into 
each other. 
The Marsh Frog is usually found in the vicinity of ponds and marshes, 
though occasionally, in the morning, after a heavy dew, it is seen at some 
distance from water. Its note isa prolonged, grating sound, and its odor 
strong and offensive.
