THE POUCHED FROG. 447 
This pretty creature is mostly found upon trees, clinging either to their 
branches or leaves, and being generally in the habit of attaching itself to the 
under side of the leaves, which it resembles so strongly in colour, that it is 
almost invisible even when its situation is pointed out. When kept in a 
fern-case, it 1s fond of ascending the perpendicular glass sides, and there 
sticking firmly and motionless, its legs drawn closely to the body, and its 
abdomen flattened against the glass. 
The food of the Tree-Frog consists almost entirely of insects, worms, and 
similar creatures, which are captured as they pass near the leaf whereto their 
green foe is adhering. It is seldom seen on the ground except during the breed- 
ing season, when it seeks the water, and there deposits its eggs much in the 
same manner as the common Frog. The tadpole is hatched rather late in 
the season, and does not attain its perfect form until two full wonths have 
elapsed. Like the Toad, the Tree-Frog swallows its skin after the change. 
The common Tree-Frog is wonderfully tenacious of life, suffering the severest 
wounds without seeming to be much distressed, and having even been frozen 
quite stiff in a mass of ice without perishing. 
The colour of this species is green above, sometimes spotted with olive, 
and a greyish yellow streak runs through each eye towards the sides, where 
it becomes gradually fainter, and is at last lost in the green colour of the skin. 
in some specimens there is a greyish spot on the loins. Below, it is of a

paler hue, and a black streak runs along the side, dividing the vivid green of 
the back from the white hue of the abdomen. 
IN the POUCHED FROG we find a most singular example of structure, the 
female being furnished with a pouch on her back, in which the eggs are 
placed when hatched, and carried about for a considerable period. 
This pouch is clearly analogous to the living cradle of the marsupial 
animals, It is not merely developed when wanted, but is permanent, and
