NUMBERS OF GECKOS 
bold, occurring in the most frequented rooms of those 
houses. Geckos, like most lizards, are carnivorous in 
habit. This giant form, relatively speaking, eats 
insects, small birds, and is even at times a cannibal. 
So firmly can it adhere to surfaces that it is used in 
the pastime of fishing for hats with felonious intent ; the 
gecko is let down on to the hat of some unsuspecting 
passer by, and is hauled up together with the hat, just 
as the remora or sucking fish is used to fish for turtles. 
Geckos are very numerous in species; nearly three 
hundred exist, and they are found all over the world in 
its warmer parts. The nearest point to this country 
where they occur is the south of France, where lives 
Tarentola mauritanica, a smaller species than that which 
we have been considering. The visitor to the Zoo 
will not have the opportunity of seeing so large a num- 
ber of species, for something under twenty is the total 
number of different forms which have been on exhibit 
in that institution. 
THE FRILLED LIZARD 
As the frilled lizard, Chlamydosaurus kingt, has up 
to the present been only once exhibited at the Zoological 
Gardens, it is possible that this chapter may not be of 
great use to the visitor ; on the other hand the reptile 
seems, according to Mr. Savile Kent, to be not un- 
common in Queensland and some other parts of tropical 
Australia, and it is always possible, therefore, that 
there may be specimens on view in Regent’s Park 
Gardens. It is in fact frequently the case at the Zoo 
that an animal reputed rare has subsequently turned 
up in greater numbers, so as to be no longer a rarity 
at the menagerie. The frilled lizard belongs to a 
family known as Agamide, concerning which we shall 
have something to say by way of an appendix to the 
account of the representative of the family which has
