CoLEnso.—On a supposed new Species of Naultinus. 258 
offensive, yet still living (though not eating), dirtying the others with its 
discharges, anal now as well as aural, I threw it out into the field 
On the 16th November I looked at my lizards, as usual, in the morning 
before going to town, and found them right; but on my return, at one 
o'clock, p.m., the biggest spotted one (which I believe to be a male) had cast its 
skin !—or epidermis !—it was nearly all got off, and almost entire. I helped 
it, by holding its scurf, to draw out its tail. I was much pleased at this 
for several reasons—some I may here mention: (1.) The beautiful new 
sparkling vivid green colour of the animal! now, for the first time seen in its 
living beauty. (2.) The cast-skin, or seurf, truly a curious object ; showing, 
not only every scale, and joint, and spot, and marking, including the little 
fingers of its tiny gloves close down to its claws; but, also, the very outer 
skin or film of its labial scales, and of its eyes. (8.) The cast skin was not 
at all coloured green like the animal, but was merely of a light grey colour 
with lighter patches corresponding with its large white spots. (4.) It had- 
commenced breaking away under the chin, and so peeled off from its snout 
regularly down its back and body to the tip of its tail. (5.) I might now 
expect to know something certain of this animal’s economy (and of its con- 
geners), as to how often in the year it would cast its skin. 
One of the spotted young ones (which I shall term No. 1.) also cast its 
skin on the 6th December; like that of the large male it commenced at the 
snout, but it came away in fragments—perhaps owing to its being both 
young and tender. 
On the 8th December the second young green lizard died, just as the 
former young one died, from starvation. This one had, in common with 
the two young spotted ones, plenty of small flies (now more easily obtained 
as the summer advanced), but it wanted the power to catch any. 
About the 12th December the two remaining adult lizards seemed to be 
getting into a diseased state; the handsome male, which had so lately shed 
its outer skin, had something the matter with its ear, from which a bloody 
discharge was oozing (resembling in a smaller degree the early diseased 
state of the adult one that died), while the adult female was restless, swelled 
in the lower abdomen, and discharging a bloody mixture from its anus; 
finding this one getting rapidly worse, with its anus greatly swelled and 
blotchy—starred all round the margin as it were in a curious regular man- 
ner—lI lost no time in putting it into a bottle of spirits, and, on my going 
to look at it some ten minutes after, I found, to my astonishment, no less 
than 26 large living larve of that red-brown flesh-fly had been discharged 
from its anus! These were each 5 lines long, and it was their posterior 
ends compacted together and jutting out from the lizard’s anus which 
given it in that part its peculiar appearance. Now it flashed across my
