Several other lizards belonging to the famil\- group of the Agamas ha\'e been demon- strated by the writer to mo\'c in the same manner as the frilled species. Leseur'S W.'\TER-Eiz.\RD, also a (Jueensland form, which attains to a length of 3 or 4 feet, is a notable example in this connection. As implied b_\- its name, it is semi-aquatic in its habits. It frequents scrubs in the neighbourhood of river-banks and backwaters, and passes a considerable portion of its time in shallow water with onl)^ its nostrils elevated above the surface. It is a most expert swimmer, sculling itself with grace and rapidity, aided onl_\- by its long, laterally compressed tail. Examples brought to England and kept alive for some }'ears b}' the writer were observed, in hot weather mure particularly, to sleep at nights irt their water-tanks. The several instances of bipedal locomotion among living lizards, as here chronicled, are of especial interest in correlation with the circumstance that certain extinct Dinosaurs habitually progressed on their hind limbs onl\'. They, in fact, have left " footprints on the sands of time " which indubitably prove this assumption. There is, howexer, no relationship between the tx\'o groups, and the resemblance is une of pure analogy, just as both bats and birds fly, although they have no kinship. Among other interesting lizards included in the Agama Family, mention may be made of the singular JEW or Be.\RDED ) of Australia — a flattened, broad-set form, some 14 or 15 inches long, brown in hue, and clothed with rough imbricated scales, but w hose chief peculiarity consists of the pansivebeard-like development of the cuticle I immediately underneath the animal's chin.
