in larger or smaller numbers over Asia, Africa, and America, and are especially 
abundant in Australia, where they form by far the greater moiety of the ophidian 
fauna. All of them—doubtless on account of the immunity from attack conferred 
by their poisonous character—are remarkable for the beauty of their coloration. 
The coral-snake and its allies constitute a genus well represented in the 
warmer regions of America, but also occurring sparingly in South Africa. They 
are small, although rather long and plump serpents, with the body cylindrical, the 
head flattened and scarcely differentiated from the neck, and the tail short. The 
small eye has a circular pupil, the mouth is narrow, and the jaws admit of but 
slight dilatation. Superiorly, the body is clothed with equal-sized, smooth scales, 
arranged in fifteen rows; while interiorly the body-shields are rounded, the anal

one being undivided, and the shields beneath the tail arranged in a double series. 
Behind the fangs, the teeth are all small. One of the handsomest members of a 
beautiful group is the coral-snake, which inhabits a large part of South America, 
and also occurs in the West Indies. Attaining a length of from 2 feet to 2| feet, 
this snake has its ground-colour a brilliant cinnabar-red, with a special lustre on 
the under-parts. On the body this red colour is divided into sections of equal 
length by broad black rings, bordered by more or less distinct greenish white 
margins; all the red and greenish portions showing black spots on the tips of the 
scales. The front of the head, as far back as the hinder end of the frontal shields, 
is bluish black; at the back of the parietal shields there commences a greenish 
white crossband, running behind the eye, and occupying the whole of the lower 
jaw; and after this comes a black neck-ring, followed by one of the red spaces of 
the body. As a rule, instead of being red, the tail has alternations of black and 
whitish rings, with its tip whitish. The coral-snake is generally met with in
