This classification includes an enormous number of ‘ species and varieties of reptile, including Geckos, Chameleons and the familiar British Slow or Blind Worm, often unjustly persecuted as a snake. Given a vivarium or a greenhouse, even the most delicate of the exotic Lizards will do very well as pets, and as they are all harmless, and quite easily fed and housed, they make admirable pets and appropriate adjuncts to a greenhouse or vivarium. They are, relatively, long lived; the Eyed-Lizard, for instance, is credited with living ten years or more, though other species do not live quite so long as this, Some species are readily tamed and show a remarkable degree of intelligence. All species are carnivorous, but the actual type of food varies according to the size and habits of the reptile; the Blm-tongued Lizard eats slugs and snails, and enjoys a little finely chopped raw meat, and the ugly but inoffensive Prickly Lizard eats meal-worms, grubs, gentles and small beetles. Both these species should have a pot of water in their quarters, and at least a three inch depth of sand for hibernating. The Chameleon eats any small insects and flies, and only takes water which has been sprayed on the leaves in its compound. This animal is very difficult to rear on account of its susceptibility to cold, but it is an interesting pet. The popu lar Eyed-Lizard is very easily tamed, and will generally take food from the hand; but owing to its size and its voracious habits, should not be allowed to associate with others of its kind. This species eats mice, worms, and cockroaches, as also does the Vivaparous Lizard. The beautiful Green Lizard (beloved of schoolboys) will eat any kind of insect, including butterflies. The much maligned Slow Worm is the gardener’s friend; he eats every kind of garden pest, and, in fact, is as useful to the gardener in this respect as the no-less maligned Toad. A peculiarity of the Lizards is the marvellous reproductivity displayed in replacing a broken tail.
