two or three hours after he killed the first. This discovery, that 
there were two instead of only one, accounted for what had pre- 
viously often surprised me, namely that sometimes the animal was 
of a brownish-green hue, and when of that colour always appeared 
larger than when it looked blackish. It therefore appears plain that 
they must have been male and female; and, if that is correct, the 
male was by far the larger and handsomer. 
«The male, as I consider it, was the one I saw dead after it was 
shot. It was about from 22 to 24 inches long, but the tail did not 
appear so long in proportion, as it grew older, as it seemed when 
first discovered. I opened the animal, and found it full of pieces of 
guinea-hen-weed, some digested, some half-digested, and a large 
quantity quite fresh, which is accounted for by its being early in the 
morning, say nine o’clock, when it was shot. I may mention that I 
put the carcass into three or four different sorts of ants’ nests,—the 
common, the stinging black, and the large red ant,—not one of which 
would touch it; and when I forced them into the carcass, and put 
part of their nests in it, they ran away from it as quickly as possible. 
I did this under the hope of getting his skeleton.” 
To this last observation Mr. Hill has appended the following note : 
—‘ This dislike for the flesh of the lizard may have resulted from 
the odour of the guinea-hen-weed, on which it had recently fed. 
The whole flesh would be imbued with the intolerable garlic-like 
scent.”
