148 THE VIVARIUM. 
The Horned Lizards of the Iyuwanide correspond, to a certain 
extent, with the Moloch Lizards of the Agamde. The genus 
Phrynosoma contains at least twelve species. 
The members of the Amphisbzenidz family are snake-like 
Lizards, without legs. The Chirotes canaliculatus has, however, 
two fore-legs, each with four clawed toes; but this is the only 
exception. The name is derived from Greek words, which 
mean an animal that can walk in both directions. These 
creatures live in burrows in the ground, and in the narrow 
galleries which they make there they are able to crawl in 
either direction. Their manner of progression is different from 
that of other legless Reptiles. Instead of moving their body — 
laterally as snakes do, they move it in vertical undulation, just 
as serpents were often represented in old pictures to be doing. 
Some of these creatures are occasionally brought into this 
country, where they may, with care, be kept in confinement. 
There is still much to be learnt concerning these curious Lizards, 
so that it would be quite worth one’s while to tend them and 
study them if they should happen to fall into his possession. 
They ought to be kept in a rather narrow though long case, having 
four glass sides, the bottom of which should be rather thickly 
covered with earth. Through the glass some of their habits, 
while under ground, may be observed. They are hardy while in 
confinement. 
The Amphisbzenidz have worm-like bodies well suited to their 
underground life. The eyes are small, and covered with skin ; 
the ears are not exposed, and the tail is very short. There are 
about eleven genera and sixty-five species. Most of the species 
come from America. 
The Grey Amphisbeena (Blanus cinereus) is the most easy of 
its family to be obtained in this country. It is a native of Spain, 
Portugal, Morocco, and Algiers. It is about as thick as one’s 
finger, and reaches a length of about 8in. It is of a brownish 
flesh-colour, the segments of the body being of a darker shade. 
The lateral iine is well marked, and there are generally six 
preanal pores. 
The White Amphisbena (4. alba), which comes from 
Brazil, sometimes is nearly 2ft. in length. In captivity these
