Among the arachnids, the scorpions are especially stenothermal, warmth-limited animals; the whip scorpions (Pedipalpi) are confined entirely to the tropics. The reptiles form another division of the animal kingdom that is composed of such stenothermal animals. In the direc- tion of the poles, their numbers diminish rapidly. In the entire.

Mediterranean region there are 140 species, with 59 species in southern Europe, 21 in central Europe, only 6 in northern Europe; and only 2 at Leningrad. Germany with an area of 540,000 sq. km. harbors 12 species, Java with 132,000 sq. km. has 122. The wrarmer it is, the larger the reptiles become and the more active they are. The wall lizards {Lacerta muralis) of the Mediterranean region reach a much larger size than those in Germany, and the southern green lizards (L. viridis) may be double the length of the The greater activity of the reptiles of warm zones is reflected in the more rapid locomotion of the lizards, which may even run upright on their hind legs, notably the American Crotaphytus and Basiliscus and the Aus- tralian Chlamydosaurus2® (Fig. 110).
