small. The tail is about as long as the head and body. The 
upper parts are of an olive colour, the lower surfaces being of a 
lighter shade. The Lizard is a native of Ceylon, and grows to 
a length of 15in. It is both carnivorous and herbivorous. In 
confinement it should be provided with mealworms, cockroaches, 
beetles, lettuces, ripe fruit, and boiled rice. Except in the hottest 
weather, its case ought to be artificially heated. 
The Bloodsucker (Calotes versicolor) is a beautiful and interest- 
ing Lizard, and common in India and Ceylon. It has two spines, . 
or separate bunches of spines, one in front of the other, above 
each ear-opening. The adults of this species possess a crest 
running along the neck and back: in the young the crest only 
reaches to about the middle of the back. In describing the 
Bloodsucker’s colour, Dr. Giinther says that the “ ground-colour 
is generally a light brownish-olive, but the Lizard can change it 
to bright red, to black, and to a mixture of both. This change 
is sometimes confined to the head, at other times diffused over the 
whole body and tail. A common state in which it may be seen 
(as stated by Mr. Jerdon) is seated on a hedge or bush, with the tail 
and limbs black, head and neck yellow, picked out with red, and the 
rest of the body red.”” The name ‘‘ Bloodsucker ” has been given 
vrobably because of the red colour which is sometimes seen on the 
animal’s head and neck. 
The female is said to lay about ten eggs, about the size of those 
of a sparrow, and which hatch, according to temperature, in from 
eight to ten weeks. Ina state of nature this Lizard feeds upon 
insects, young leaves, and berries, and in captivity it may be pro- 
vided, as food, with beetles, mealworms, cockroaches, other small 
animals of a similar nature, young lettuces, and ripe fruit. It 
must be kept, at any rate during the greater part of the year, in 
a heated Vivarium, and as its habits are arboreal, it should have 
access to an orange-tree or some other tree of a like kind, upon 
which to climb and sleep. The entire length of the Bloodsucker 
is about 15in., the tail being a little more than twice the length 
of the head and body. 
The Bearded Lizard (Amphibolurus barbatus).—This very 
strange-looking animal is hardy and interesting. When it is in a 
state of irritation, and most of the members of this family are
