The next family, the Anadiad^e, contains, as far as is known, only one species, the 
Eyed At ta.pt a ( Anadia ocellata ), thought to inhabit tropical America. In this creature the 
lower eyelids are pellucid, the scales of the back and sides six-sided and not ovei lapping each 
other, while those of the abdomen are squared. The limbs are four in number, and there are 
five unequal and rather flattened toes on each foot. The color of this species is pale brown, 
with a bronze gloss, deepening on the sides, and having some white spots edged with black 
towards the front. Beneath it is shining white. 
Ix the family of the Chirocolhue there is likewise only one species, called the Chiro- 
cole ( Heterodactylus imbricatus ), a native of Brazil. This creature has a double collar, and 
the ears are hidden beneath the skin. The scales of the back, the sides and the tail, are six- 
sided, rather sharp, arranged in regular rings, and furnished with keels. Those of the abdo- 
men are squared and arranged longitudinally in six rows. There are four short legs, with five 
toes on each foot, the thumb of the fore-limbs being only rudimentary. The color of the 
Chirocole is brown, with a pale streak on each side. 
The fourth family is the Cercosauridjs, containing two genera. These animals have the 
ears distinct, the throat with a double series of shields, and the collar distinct. On the back 
and upper part of the tail the scales are large, boldly keeled, and arranged into a regular 
longitudinal series. The scales of the under portions are squared and flat. There are four 
limbs, each with five unequal toes. A good type of this family is afforded by the Eyed Cer- 
cosaurus (Cercosaura ocellata). The body of this creature is long and rather cylindrical. Its 
color is black, with four white streaks, the head and the under parts are yellowish, and the 
sides are sprinkled with green, and variegated with eight or nine white spots edged with black. 
Our last example of the Cyclosaurian reptiles is the Ahguijste Lizard, or Champs aura, 
the only representative of its family. 
The Anguine Lizard is a native of Southern Africa, and is obtained from the Cape of Good 
Hope. Of its habits there is but little known. It is a curious-looking creature, exceedingly 
snake-like in general appearance, its four limbs being of the most rudimentary character, 
small,' delicate, feeble, not even separated into toes at the extremity, but ending in a single 
claw, as if the whole limb were only composed of one small joint. These imperfect limbs are 
wholly useless for progression, those of the anterior extremity being hardly larger than the 
long, narrow scales with which the body is covered, and the hinder pair exhibiting but very 
little more development. 
So perfectly serpentine is the form of this creature, that the mark of separation between 
the tail and body is so slightly defined that the precise line of junction is almost invisible ; 
whereas, in the common blind- worm, itself a most snake-like reptile, the line of demarcation is 
plainly shown by a decided diminution in the diameter. The tail is very long and slender, 
measuring more than twice the length of the body. 
The head of the Anguine Lizard is covered with regular, many-sided shields, and the 
temples, and the whole of the body and tail are clothed with scales, their edges projecting 
boldly, and arranged in a series of regular rings, or ‘‘whorls.” Along the back there are six 
rows of broad scales, and on the sides and abdomen the scales are long, narrow, and with a 
decided keel running along their central line. There is no groove along the sides, which are 
rounded. Upon the head the plates are rather long, keeled, and project very slightly over 
each other. The ears are distinct. The color of the Anguine Lizard is brown, and along each 
side runs a long yellow streak. 
GEISSOSAURI. 
A secohd tribe of Lizards now comes before our notice. These are the Geissosauri, a 
title derived from two Greek words, the former signifying the eaves of a house, and the latter 
a Lizard. As in this tribe there are many families, and more than eighty genera, it will be
