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 w^hen it looked blackish. It therefore aj^pears plain that 

 they must have been male and female ; and, if that is correct, the 

 male was by far the larger and handsomer. 



" 'J'he 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."
