thin, slender, versatile, and peculiarly arched, so as to 
give them the power of grasping very strongly. Of 
these, the Beautiful Cyrtodactyle ( Cyrtodactylus pul- 
chellus ), from India, and the Ocellated Cyrtodactyle 
( Cyrt . ocellatus ) have the tail slender and round, while 
the Flat-tailed Cyrtodactyle ( Lacerta platura ), of New 
Holland, has a cordiform, expanded tail. 
Case 4 contains the 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 Agamse. 
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 Bronchocelae 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 armato ), 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
