The small group of GiRDLE-TAlLED Lizards belongs exclusively to the African and Madagascan regions, its typical repre- sentative being the Cape and Orange River Colony species, illustrated on page 575. The symmetrical whorls of long, spinous scales encircling the tail in this and the allied forms constitute a prominent feature, and have originated the popular name of Girdle- tails. The most aberrant representatives of the Lizard Tribe, with regard to one very important characteristic, are undoubtedly the two species of Heloderm, or " SiLATiCA," as they are called by the natives. These reptiles (page 576) occupy the unenviable position of being the only known lizards which possess poisonous properties, their bite having been demonstrated to be fatal to smaller mammals, and to be attended by very serious symptoms in the case of human subjects being bitten. The more common MEXICAN Heloderm has been in residence at the Zoo for man_\' j'ears ; it attains to a length of from iS to 20 inches, and its stout, squat bod)', short limbs, warty skin, and peculiar colouring are calculated at first sight to awaken a feeling of revulsion in the beholder. Like the wasp, the salamander, and other animals whose conspicuous tints indicate their poisonous or other baneful properties, the heloderm is distinguished b\' a lurid ground- colour, varying in individuals from yellow-orange to flesh-pinlc, upon which are superimposed bold, network-like markings of blue-black or dark brown tints.
