family and surface

TEJU, or TEGUEXIN, a large lizard (Tupinatnbir teguexin), inhabiting tropical America. The upper parts are deep-black, mot tled with green and yellow ; the sides show two rows of white spots; and the under parts are yellow, marked with black stripes. A full grown specimen may be three feet in length, mostly tail. These lizards frequent forests and plantations, are carnivorous and their strength and speed enable them to catch a great variety of animals, including barnyard chickens and eggs. They are consequently hunted, not only as pests, but because they are themselves good to eat. They dwell in burrows, lay hard-shelled eggs in the ground and defend themselves by vigorous lashing of the tail. Their general re semblance to the Egyptian Voranus gives them the borrowed name "salvator" in some places. This lizard represents an American family, the Tejidx, with long forked tongues largely cov ered with scale-like papillae. The teeth are

solid and implanted, almost on the edge of the jaw and are therefore intermediate between acrodont and pleurodont. The body is covered with small scales (osteoderms are absent) or the skin may be simply granular above; the under surface is covered with larger scales, generally arranged in transverse rows. "This large family,' says Gadow, "which comprises nearly 40 genera with more than 100 species, exhibits great diversity of form. Some are inhabitants of forests and are arboreal, while others are strictly terrestrial, preferring hot and sandy plains, or they dwell below the surface and are transformed into almost limbless and blindworm-shaped creatures.' Representatives of the family are spread from Texas and Utah to the borders of Patagonia.
