MOVABLE ARMOUR 
lizard. They clash with a vast series of important facts 
which differentiate mammals from animals lying lower 
in the series, which have been already enumerated, and, 
quite apart from the fact that they differ in many details 
from the carapace of the tortoise or turtle, no more 
affine the two than does the beak of the tortoise, or the 
Ornithorhynchus, bridge over the gulf between those 
creatures and the bird. The huge, and we may almost 
say, ‘‘ therefore,’ extinct, Glyptodons, which were allies 
of the armadillos, were boxed up in their carapaces ; 
the modern armadillos enjoy a freedom of movement 
within theirs, since the bony pieces are often distributed 
in bands. A species often to be seen at the Zoo, and 
known as Tolypeutes tricinctus, has its chest protected, 
as ought his to be who first crosses the seas, by a triple 
band, not of brass, but of bone. In others again there 
are six bands ; and the tiny Chlamydophorus (which will 
probably not be seen at the Zoc) has a point of likeness 
to the effete Glyptodonts, in having a rigid box envelop- 
ing it without jointing. So thoroughly movable are 
these bands as a rule, that the armadillo can roll up into 
a ball like its namesake, the armadillo woodlouse, and 
thus be with impunity played at ball with by a hungry 
jaguar, intent rather on solid food than playful trifling. 
Nor could the jaguar easily solve the difficulty by swal- 
lowing the armadillo like a pill. In its own choice of 
food the armadillo is decidedly a carrion lover, and ap- 
proaches its food after the devious fashion of a burying 
beetle. Instead of openly making for the carcass, the 
armadillo circuitously tunnels underground and comes 
up underneath it. We are told that on the pampas a 
carcass is rarely found that has not beneath it a tunnel 
formed by some epicurean armadillo intent on luxury. 
At the Zoo this taste is severely restricted, and a diet of 
pap and chopped meat offered in its place. Mr. Hudson 
relates another way the armadillo has of providing itself
