It is chiefly in the ftru&ure of the head that this 
difference appears, and its Angularity induced me to 
obferve it with attention ; for the head is very large 
in proportion to the reft of this animal, and all 
others of the fame clafs 3 and the more fo, if we 
meafure from the two anterior flat proceftes, to the 
pofterior extremity or procefs of the cranium , which 
meafures three inches and a quarter. This pofterior 
procefs extends backwards, over the neck, to the flrft 
vertical procefs of the fpine ; and the interior procefles* 
one on each Ade, project forwards and upwards in 
an oblique dire&ion over the nafal hole, and are 
bluntly ferrated all round ; the furface of the entire 
face is covered with tubercles and fcales, which, by 
being in a dry ftate, have loft their protuberance and 
luftre, which the fcales certainly were endowed with 
while the animal was alive. 
The length of the two mandibles is equal, and is 
two inches and a quarter from the articulation of the 
lower with the upper jaw, to the apex of each; both 
being furnifhed with a Ane fet of fmall pointed teeth; 
all of a Aze, and fofet, that, upon the animal’s clof- 
ing his mouth, the teeth do not meet, but thofe of 
the upper fall in with thofe of the under alternately. 
There are no molares nor canine teeth. 
The orbits are extremely large and deep, fo that 
this Cameleon muft have had very great eyes, and 
very globular; for they are each more than a third 
of the whole length of the mandible in diameter. 
From a clofe infpecftion of the fkin, which is now 
contradled and dried clofe to the Aceleton, it appears 
fcaled all over ; the larger fcales are upon part of the 
head and upon the Ades of the neck ; the fmaller, un- 
der the jaws, upon the neck, and over the whole
