crocodile, who are, therefore, it is more than probable, no friends of
the monitors. The Egyptian would love the monitor for feeding upon the
crocodile germ, as much as for his timely warning of the approach of
the uncouth enemy. The curious heloderms, from Mexico, with their
ophidian teeth, lie at the bottom of the fifth case: they are
supposed, but as yet on insufficient grounds, to be poisonous. In the
next case (6) are the lizards of tropical America, called safeguards.
Their reputed peculiarity is that, of beating beehives till they
compel the bees to retire, and then feasting upon the sweet booty: in
the same case with these, is the lizard with the double-keeled tail,
known as the crocodilurus. The visitor next faces a case (7) of
Serpent Lizards, which do not deserve their reputation for poisonous
properties, being quite harmless: here, also, are the Skinks and other
varieties, including the blind worms with their hidden legs. Having
dismissed the serpent lizards, the visitor will notice the Night
Lizards and Guanas. The former are inhabitants of warm climates, and
from the ease with which they can adapt themselves to any positions,
they may be troublesome visitors; they can run with ease about the
walls and ceilings of rooms, like flies; and their propensity is to
roam abroad in the darkness of the night. Their broad, ugly heads, and
repulsive general appearance, have won for them the character of
poisonous reptiles, but the truth is they are harmless. The Crested
Lizards which the visitor will notice hereabouts, are the American
fruit-eating species, celebrated for violent quarrelling among
themselves, and for their power of changing colour with great
rapidity. They do not crawl upon the earth, but live on trees, the
fruits of which sustain them. Here, too, are the Anoles, with their
distended toes, that enable them to imitate the crawling feats of the
night lizards. The tenth case devoted to the lizard tribe, is the most
interesting of the series. It contains the family of lizards known as
