But among the mammals this cloaca is only permanent in the Monotremes, as it is in all the birds, reptiles, and amphibia. The use that we have hitherto made of our biogenetic law will give the reader an idea how far we may trust its guidance in phylogenetic investigation.

Its predominating colour was a fleshy red, or coral, from whence it has its name, for both Don Pablo and Guapo, as soon as they saw it, pronounced it the "coral snake." Beautiful as it appeared, all knew that it was one of the most poisonous of serpents one of the most dreaded of South American reptiles.

Reptiles must live for some good purpose. All things do don't you think?" Then, before he could make a rejoinder, she went on: "I sometimes feel that these creatures were originally placed here to encourage other and higher forms of life to come and locate in the desert were placed here, in other words, to prove that life is possible in all this desolation." He glanced at her.

Woe betide the belated pedestrian, or even horseman, if he happens to pass under a tree which forms the ambuscade of a coralillo snake! Cobras and other reptiles seldom attack men, and will generally try to avoid them, unless accidentally trodden upon, but these guerilleros of the forest, the tree serpents, lie in wait for their victims.

They show us that the birds are the descendants of reptiles, coming off from them as a branch does from the parent tree. The tortoises began in this series of rocks. At first they are marine or swimming forms, the box-turtles coming later. Here too begin many of the higher insects.

Turtles and tortoises are not found until the early Jurassic, when they already possessed the peculiar characteristics which set them off so sharply from other reptiles. They seem to have lived at first in shallow water and in swamps, and it is not until after the end of the Mesozoic that some of the order became adapted to life on the land.

The Indian kept the shaft to one side while he diligently prodded the reptiles with the willow. When he had enraged them so that they began to strike blindly at each other and at themselves, he lowered the shaft and let them drive their fangs into the meat.

For a moment I was puzzled to account for the thing, until I realized that the reptiles, being deaf, could not have been disturbed by the noise my body made when it hit the water, and that as there is no such thing as time within Pellucidar there was no telling how long I had been beneath the surface.

But the sight come back all right, and quick too like as I've seen a paralizite get up all at once and walk as though he'd never been locoed. Why, God Almighty don't let men like Ingolby be done like that by reptiles same's Marchand." "You believe in God Almighty?" she said half-wonderingly, yet with gratitude in her tone. "You understand about God?"

I returned to my hut: the flat turf in the vicinity of the village was strewn with the bones of immense fish, hippopotami, and crocodiles; but the latter reptiles were merely caught in revenge for any outrage committed by them, as their flesh was looked upon with disgust by the natives of Unyoro.
