The _Cursoria elegans_ is said to be from Afghanistan; _Eryx iacalus_ inhabits Greece and Egypt; and there is also _E. thebaicus_ in the latter country, and _E. Johnii_ in India. Another Indian species is the _Gongylophis conicus_, which the natives erroneously persist in declaring to be Venemous. The _Eryx Johnii_ is frequently found in the possession of the serpent-charmers of its native country, who mutilate the end of its short, thick tail in such a manner that the scarred extremity somewhat resembles the form of the head. Such specimens are shewn as deadly Two-headed Snakes, and, as such, are occasionally brought alive to Europe. An example of this species lived in the London Zoological Gardens for about eight years, and fed regularly on young Mice. The keeper assured Dr. Günther that it frequently covered its prey with saliva. It always kept itself hidden below the gravel at the bottom of its cage. This species attains to a length of nearly four feet, the tail measuring but four inches. The _Acrochordidæ_ constitute a very remarkable small family, of which one genus is terrene, and another highly aquatic in its habits. Whether a third genus, the Javanese _Xenodermus_, should be referred to it, is doubtful in the opinion of Dr. Günther. These Snakes have the body of moderate length, rounded, or slightly compressed, and covered with small wart-like, not imbricate, tubercular or spiny scales; tail rather short, prehensile; head rather small, not distinctly separated from the neck, and covered with scales like those of the body; nostrils close together, at the top of the snout; teeth short, but strong, of nearly equal size, and situate both in the jaws and on the palate. These serpents are viviparous. One of them, _Acrochordus javanicus_, inhabits Java and the Malayan peninsula, where it is considered rare. It grows to a length of eight feet, and its habits are terrene. The late Dr. Cantor justly compares its physiognomy to that of a thorough-bred bull-dog; a female in his possession brought forth no fewer than twenty-seven young in the course of about twenty-five minutes; they were active, and bit fiercely. Hornstedt found a quantity of undigested fruits in the stomach of this Serpent! Upon which Dr. Günther remarks that no opportunity of making further observations on the habits of this remarkable Snake should be lost. The aquatic member of this family, _Chersydrus granulatus_, inhabits from the coasts of India to those of New Guinea and the Philippine Islands. Sometimes it is met with at a distance of three or four miles from the shore. Mr. W. Theobald remarks that it is plentiful in the Bassein River (in British Burmah), in salt water below Gnaputau, and, with various other Sea Snakes, is frequently swept by the tide into the fishing baskets of the natives. The ebb-tide, running like a sluice, sweeps various Fishes, Crustaceans, Snakes, and even Porpoises occasionally, into the broad mouths of those baskets, where they are at
