11 6 THE LIVING ANIMALS OF THE WORLD’ 
TUBERCULATED IGUANA 
This species is esteemed for food by American Indians ' 
interest in some neighbour’s hen- 
roost, and receiv'ed across its tail a 
stroke with a spade or other cutting 
instrument that was intended for a 
more vital region. Disgusted by such 
unfriendly treatment, it evidently 
determined that free board and lodg- 
ing at the hands of its former owner, 
albeit with the sacrifice of freedom, 
was a pleasanter line of life than 
liberty and a precarious commissariat, 
with added bodily risks. An almost 
identical episode of the voluntary 
return to captivity of an escaped 
monitor has been reported to the 
Avriter of a species from Borneo by 
Dr. G. D. Haviland. 
The monitors, as a rule, are not 
distinguished for brilliancy of colouring, shades and mottlings of brown or black being usually 
dominant. The male of the Australian lace-lizard, after 
newly changing its coat, is, how'ever, an exception. In 
addition to the highly ornate lace-like reticulated pattern 
of its skin-markings, previously referred to, the throat of the 
animal is resplendent with mingled tints of sky-blue and 
lemon-yellow. It is necessary, however, to observe that its 
natural surroundings and the ardent rays of a sub-tropical 
sun are requisite to bring these brighter tints to their full 
development. Examples kept in close confinement in the 
London Zoological Gardens }field little or no indication of 
their colour potentialities. 
While the Monitor Family is not represented on the 
American Continent, we find there another group of lizards 
whose members are of considerable size, and agree in their 
carnivorous propensities and general habits in a marked manner with the Monitors. These 
are the “ Gre.vvei) ” Liz.vrds, named with reference to the peculiar skin-folding on their 
legs. One of the largest and most familiarly known representatives of this group is the 
Tegue.xix, or Di.\i\iond-liz.\rd, indigenous to the greater portion of tropical South America, 
and also to the West Indies. This lizard attains to a total length of a yard or more, 
^ and is of a robust and 
thick-set build, with the 
hind limbs much longer and

WALL-LIZARD 
This species is particularly abundant in Italy 
stouter than the front ones. 
The colour of the teguexin is 
also notable, the ground-tint 
being olive or tawny yellow, 
upon which are superimposed 
black bands and markings 
which for the most part take 
a transverse direction. Like 
the Monitors, the tugue.xin 
in captivity exhibits a sulky 
and aggressive disposition.
