LIZARDS. 107 
varying between 7O0deg. and 85deg. Fahr. The food may 
consist of cockroaches, mealworms, tiny frogs, small mice, and 
raw meat. The price of this Reptile, according to supply, 
ranges from 7s. 6d. to £2. 
The Rough-scaled Zonure (Zonurus cordylus).—This Lizard 
differs from the last in having almost smooth head-shields. This, 
however, by no means is the only difference between the two 
Reptiles. The scales of the back are large, arranged in belts, 
tiled, and narrowing to a pomt, often serrated. Those on the 
sides are more strongly keeled still, and there is a lateral fold. 
The ventral scales are smooth, broad, quadrangular, and slightly 
tiled. The limbs have large, keeled, spinose, and tiled sides. 
The tail has ‘‘ whorls of large, strongly-keeled, spinose, serrated 
scales, the spines strongest on the sides.”” The upper parts of 
the body are a dark-brown, the lower, a greenish-white. The 
entire length of the animal is about 7in. It may be treated in 
the same way as suggested for the Derbian Zonure. It also is a 
native of South Africa. 
According to Mr. Boulenger, the important family of Angiwda 
contains seven genera, which, for the most part differ in out- 
ward appearance very much from each other. Some have well- 
developed limbs, some have limbs scarcely visible and useless, 
and others have no external limbs at all. But every member 
of the family has a tongue, which may be described as being 
formed of two parts, the posterior and larger part is thick and 
covered with hair-like eminences, called papille; the anterior 
portion is thinner, extensible, slightly forked, and covered with 
scale-like tiled papille—and a body which is protected by a kind 
of bony and imbricate plates, situated beneath the scales. There 
are also other points of resemblance or ‘‘ family likenesses,’’ which 
are of a more covert character. 
The Glass Snake (Pseudopus pallasii, Gray, or —and which 
seems a more appropriate title, but not so common a one— Ophi- 
saurus apus, Boulenger, Fig. 42, p. 109) is a very popular and an 
interesting inmate of a Vivarium. Itisalso intelligent for a Reptile, 
exceedingly hardy, living usually a great number of years in con- 
finement ; one was in the Zoological Gardens, London, I believe, 
for more than twenty years.
