The largest of these is said to be the bush-master, found in British Guiana, which, on the authority of Waterton, attains a length of fourteen feet. But the belted hamadryad of Burmah is often seen twelve to fourteen feet in length, and is a foot in circumference; and it is stated that specimens have been seen three fathoms (eighteen feet) long. If so, it is probably the largest known venomous serpent. This terrible creature feeds on other snakes, hence its scientific name, Ophiophagus elaps. Others, as the cobra and the rattlesnake, are relatively small, rarely attaining a length greater than six feet, usually not more than four feet.
