THE FAMILY AGAMID 
are, as a rule, eminently quadrupedal; they progress 
as we have already observed, slung between their fore 
and hind limbs like an eighteenth-century coach be- 
tween its hind and fore wheels. When bounding 
over level ground the frilled lizard abandons the use 
of its fore limbs, and hops kangaroo-like for yards 
together before coming to rest. This odd mode of 
progression is normal, remarks Mr. Savile Kent, “‘ when 
the animal is traversing level ground for any distance.” 
and the distance so travelled may be as much as thirty 
or forty feet without a stop. It then rests for a bit 
on all fours and afterwards resumes its leaping progress. 
It has been justly pointed out that in this the Chlamy- 
dosaurus reminds us of the extinct Dinosaurians, a race 
of reptiles of all sizes from eighty feet or so to a foot or 
two, which flourished in long bygone ages, and have 
left no living trace of themselves to-day. But the 
recollection of the similar mode of progression of some 
of these dinosaurs must not lead to the view that the 
Chlamydosaurus is their long lost heir. The modern 
group of lizards has not much in common with those 
great reptiles of the past, who are much more nearly 
related among living animals to the crocodiles and to 
birds. 
The family of the agamide, to which this lizard 
belongs, represent as it were the iguanas of the New 
World in the Old, and they are especially common in 
Australia. There are over 200 species of them placed 
in many genera of which several are usually on view at 
the Zoo. Uvomastix, with its spiny tail, is perhaps 
the one most commonly to be seen ; but the Australian 
Amphibolurus, the “ Jew lizard,” with its “‘ Newgate 
fringe ” of thick spines, is also at times accommodated 
in the Reptile House. The agamide are, as has been 
mentioned, by no means unlike the iguanas, and it 
is at least a curious coincidence that in both families
