thin, slender, versatile, and peculiarly arched, so as to ROOM X. 
give them the power of grasping very strongly. Of Nat. Hist. 
these, the Beautiful Cyrtodactyle ( Cyrtodactylus pul - 
chellus), from India, and the Ocellated Cyrtodactyle 
( Cyrt. ocellcitus) have the tail slender and round, while 
the Flat-tailed Cyrtodactyle ( Lacerta platura ), of New 
Holland, has a cordiform, expanded tail. 
Case 4 contains those Lizards which have their teeth 
placed on the edge of the jaws, and so firmly fixed to 
them as to appear part of the jaws themselves; as the 
Chameleons and Agamas. 
The Agamse ( Agama ), are placed in the upper part 
of this Case (No. 4). They present several peculiari¬ 
ties of form, and have therefore been separated into 
many groups. Some have the head Lyre-shaped, and 
the back and tail crested ( Gonyocephalus ), as, the Tiger 
Agama ( Agama tigrina). 
Other species have the head armed with spines over 
the back of the ears, and the scales large and directed 
upwards ( Calotes ), as the Common Calotes ( Lacerta 
calotes ), of a fine blue colour, and the Indian Calotes 
( Agama indica). These animals lay fusiform eggs. 
The Bronchocelse differ from the Calotes, by the 
scales of the back being small and horizontal; as the 
Blue Calotes ( Agama cristatella ), and the Long-legged 
Calotes {Agama vultuosa ); one species, the Armed 
Calotes ( Agama armata ), has a square head, and long 
subulate spines over the eyes (. Acanthosaura .). 
The true Agamse {Agama) have often bundles of 
spines on the sides of the neck, as, the Occipital Agama 
{Agama occipitalis ), the common Agama {Agama spi- 
nosa). The male of the Pondicherry Agama {Agama 
pondiceriana ), has so large a pouch under the throat, 
(which is quite wanting in the other sex,) that it 
has been separated as a genus under the name of 
Sitana . 
The Common Stellio {Lac. stellio ), which was for¬ 
merly much esteemed for its medical qualities, has 
bands
