snake-lke form, and 
others, like the illus- 
tration, with four fully- 
developed limbs. There 
is scarcely a stony knoll 
in Tropical or South 
Africa, or a precipice or 
exposed rock which 
does not afford a habitat 
for one, two, or even 
more of these individu- 
als. In such situations 
they wander carelessly 
in search of insectivor- 
ous food and warmth, 
unless alarmed by those 
they regard as enemies. 
On being closely ap- 
proached in their retreat, 
they seek concealment 
under rocks or in 
crevices, and when they 
get in such positions 
‘they are with difficulty 
captured, as by the 
prominences of their 
scales they can hold on 
with a tenacity which is 
quite surprising, offer- 
ing such a resistance as 
effectually to withstand 
any force appled from 
behind to drag them 
out, the tail breaking 
off from the body before 
the reptile is secured.
