of predatory insect called a “ praying-horse” (allied to the 
genus Mantis), found in India, has the shape and color of 
an orchid. Small insects are attracted and fall a prey to it. 
Certain Brazilian fly-catching birds have a brilliantly colored 
crest which can be displayed in the shape of a flower-cup. 
The insects attracted by the apparent flower furnish the fly- 
catcher with food. An Asiatic lizard is wholly colored like 
the sand upon which it lives except for a peculiar red fold 
of skin at each angle of the mouth. This fold is arranged 
in flower-like shape, “exactly resembling a little red flower 
which grows in the sand.” Insects attracted by these 
flowers find out their mistake too late. In the tribe of 
fishes called the “ anglers” or fishing frogs the front rays 
of the dorsal fin are prolonged in shape of long, slender fila- 
ments, the foremost and longest of which has a flattened 
and divided extremity like the bait on a hook. The fish 
conceals itself in the mud or in the cavities of a coral reef 
and waves the filaments back and forth. Small fish are at- 
tracted by the lure, mistaking it for worms writhing about 
in the water or among the weeds. As they approach they 
are ingulfed in the mouth of the angler, which in some of 
the species is of enormous size. One of these species is 
known to fishermen as the “all-mouth.” These fishes 
(Lophius piscatorius), which live in the mud, are colored 
like mud or clay. Other forms of anglers, living among 
coral reefs, are brown and red (Antennarius), their colora- 
tion imitating in minutest detail the markings and out- 
growths on the reef itself, the lure itself imitating a worm 
of the reef. In a certain group of deep-sea anglers, the sea- 
devils (Ceratiide), certain species show a still further spe- 
cialization of the curious fishing-rod. In one species (Co- 
rynolophus reinhardti) (Fig. 54), living off the coast of 
Greenland at a depth of upward of a mile, the fishing-rod 
or first dorsal spine has a luminous bulb at its tip around 
which are fleshy, worm-like streamers. At the abyssal 
depths of a mile, more or less, frequented by these sea-
