Not illustrated. 1849 edition.

It frequents dry sandy heaths and waste places, not requiring, like the Snake, the neighbourhood of water, nor swimming so readily as that species. In many parts of the country it is even more common than the Snake. The name Adder, by which it is known in many parts of England and Scotland, is anciently written nedre, and afterwards eddre, the initial n being dropped.

The head is somewhat depressed, almost oval, slightly widening behind the eyes. Grape as long as the head, ascending behind. No teeth in the upper maxillary bones, excepting the poison-fangs; a row of small teeth in the palatine bone on each side. Neck rather smaller than the back of the head, from which the body increases to nearly the middle of the entire length; the rest of the body to the vent scarcely diminishing; the tail becoming almost abruptly smaller, and tapering to its extremity, which is pointed; the tail varies in its proportion to the body, but is generally not more than one-eighth of the total length, and in some even less. The head is covered with small squamous plates, which in some specimens are regularly formed and symmetrically placed; but in others they are very irregular. There are three which are larger than the others, --namely, the vertical, and the pair of occipital plates. The scales of the back and sides are semi-oval, orshow more
