echoes from ponds during the summer nights, and with whose succulent legs 
all good eaters are happily familiar. His haunt is the marsh or shallow pond, 
where he sits on the margin and takes such prey as comes within his reach.’ 
When insect food is difficult to procure he swims along the bottom and captures 
crawfish, water-beetles and occasionally minnows. The frog , however, is himself 
persistently hunted for the market, the favorite way of capturing him being with 
rifle bullet, net, or by fishing for him with a piece of red* flannel, at which he greedily 
jumps and fastens his teeth, so that he may be taken before loosing his fangs. 
The Tree Frog, also called Spring Frog (Hyla arborea ), is a small but 
beautiful creature, considering that he is a reptile. Chameleon-like, he has the 
power to change his color when danger 
threatens, and usually adopts the hue of 
whatever perch he rests on. He has a pea- 
green back, spotted with black, and a yellow 
belly. His home is in the United States, 
^ast of the Rocky Mountains. 
The Flying Frog (. Rhachophorus rein- 
hardit ), a native of Borneo, is almost identical 
in appearance with the tree frog of our 
country, especially when in repose. Its dif¬ 
ference is noticeable when in motion, since its 
toes are very long, with a web between, by 
which it is enabled to fly, with a slight de¬ 
scent, by spreading its feet and swimming 
through the air. 
The Pond Frog is very closely allied to the bull frog, its principal difference 
being found in a glandular sac that lies on 
both sides of the neck, and which are greatly 
distended when the animal croaks. Neither 
is it so large as our bull frog, but it is a 
much better jumper, and is extremely diffi¬ 
cult to capture on account of its slyness. 
The Horned Frog ( Ceratophrys cornutus) 
is an inhabitant of South America, a country 
teeming with grotesque forms of animal life, 
but none more weirdly fantastic than this 
creature. There are several species, differing 
chiefly in size. The body is chubby, covered 
with a wrinkled skin that, from the tubercles 
thereon, seems to be eruptive. The back has 
a double ridge, calloused on the edges, meeting 
at the anus, and terminating on the head in 
two horns that rise up sharply above the eyes, 
giving the creature an impish appearance. It 
is very voracious, and does not hesitate to 
seize and gorge one of its own species, which 
its enormous mouth enables it to do. 
The Banded Toad ( Alytes obstetricans) , also called the Nurse Frog, com¬ 
mon to several parts of Europe, cannot rank with the horned frog for devilish 
FLYING FROG 
pond frog {Bombinator igneus).
