Description.-Compared with that of B. calamita, the head is rather more depressed, the snout more prominent, the canthus rostralis more distinct. The nostrils are equally distant from the anterior corners of the eyes and from the tip of the snout; the space between them is rather less than that between one of them and the lip. The eyes are equally distant from the tip of the snout and from the angles of the jaws. The interorbital space is flat and narrow, its breadth equalling two thirds of the upper eyelid's greatest breadth. The tympanum is always quite distinct, at least in its anterior half, rounded or a little higher than broad; its transversal diameter equals about half that of the eye. The cleft of the mouth extends to the level of the posterior corners of the eyes. The tongue varies much ; it is generally moderately large, elliptical, about twice as long as broad : in some Asiatic specimens it is very large, pear-shaped, its greatest breadth contained once and a third in its length, covering nearly the whole surface of the mouth; other specimens |
