On ths 16th November, the young one, No. 2, cast its skin, much broken. 
(This one only shed its skin twice during the last summer.) On two occa- 
. sions since, I have seen it have a kind of convulsion fit—once in its cage, 
and once on my hand—during which its writhings were strange, as if its 
little legs were disjointed ; its head was thrown back and its mouth stretched 
wide open, showing its capacious throat; it also uttered two faint cries 
during the fit, and once tried to bite !—but such a little easy nip, scarcely 
perceptible. 
The adult one also, while I was handling (examining) it, bit me—in its 
fashion !—and twice uttered a cry because it could not get away. Their cry 
was a grave sound, a little low croak, something like an attempt on our part 
at uttering the letter a (broad) with the mouth open. 
I have since fully proved the strong prehensile power of their tails ; they 
ean hold on by them to a cord, or small branch, or to my finger, and thus 
suspend themselves for some time. 
An acquaintance here looking at them observed, that he once saw two 
green lizards (Naultinus sp.) together near Auckland ; in endeavouring to 
capture them, one got away among the fern, and the other was unfortu- 
nately killed. He, however, noticing that its abdomen was very large 
opened it, and found two small living lizards within. This statement 
strengthens me in my supposition that this lizard is viviparous. 
The adult lizard is now casting its skin in the usual manner (November 
26th).
