stance of the tongue, in order to allow of the great difference in the 

 situation of parts with respect to one another 1 . 



The eye is large for the size of the animal. The eyelids are stiff, not 

 moveable on the eye, but they are made to move with the eye : at their 

 attachment to the orbit the skin is pliable and soft. The sclerotica is 

 thin for more than the posterior half, having the pigmentum nigrum 

 appearing through it : anteriorly it is thick and white. The cornea is 

 small. The crystalline lens is almost round. The capsula of the 

 vitreous humour is very plain. The nigrum pigmentum is very dark. 

 The lacrymal gland is white 2 . 



The abdominal viscera appear to be like those of the toads, lizards, 

 &c, consisting of a straight stomach, passing in the direction of the 

 body, then making a small inclination to the right. There it forms the 

 intestine, which is short and makes a few convolutions on itself, and 

 terminates in the colon or rectum, which is a straight gut something 

 larger than the other. There is a caecum which is short. The rugae 

 of the small intestines are like lozenges or rhomboids. The rectum has 

 two mesorectums attaching it to the loins between the kidneys. The 

 peritoneum that covers the intestine is very black. 



The liver consists of one lobe. The gall-bladder is a round body, 

 placed at the lower edge of the liver. The gall was not bitter. The 

 vena cava anterior runs on the inside of the abdominal muscles : the 

 posterior vena cava enters the lower part of the liver. 



The lungs are very singular ; they consist of two large bags, a right 

 and a left ; each bag is divided into two, longitudinally, by an imperfect 

 partition. They are composed of two parts ; one for immediate respi- 

 ration, the other as a reservoir of air. The first is the part nearest to 

 the shoulders, and is cellular or honeycombed on its inner surface, and 

 extremely tender : the other is smooth, thin in its coats, pretty strong, 

 and appears to be principally, or to terminate in, a vast number of 

 appendages or caeca 3 . On the right side they are attached to the right 

 edge of the liver the whole length of the liver ; on the left side only 

 attached to the left edge for a little way. 



The testicles were pretty large, although it had been kept some time, 

 and had died from the effects of long confinement. They were black, 

 like the intestine, and were placed pretty low down, just before the 

 upper end of the kidneys 4 . 



The chameleon is oviparous : there is one cluster of ova on each side,
