LIZARDS. 105 
Gallot’s Lizard (Lacerta gallot/) is a most interesting and lively 
Reptile, and lives a long time in confinement. It is, however, 
rather quarrelsome. The snout is long, and the head is moderate- 
ly depressed. The rostral shield does not enter the nostril, and 
there is a series of granules between the two shields immediately 
over the eye. The dorsal scales are very small, and the tail, upon 
which the scales are strongly keeled, is more than twice as long as 
the head and body. There are about twenty-five femoral pores. 
Mr. Boulenger, describing the colour of this Lizard, says that it 
is an “‘ olive-grey or dark olive above, with black and pale greenish 
spots ; females aud young with two light, black-edged longitudinal 
streaks on each side. Lower surfaces olive or blackish in the 
adult, paler in the young; throat, in the young, with angular 
grey bands converging forwards. A more or less distinct black 
band and a few whitish spots on the hinder side of the thighs.” 
This Lizard’s beauty, liveliness, hardiness, and willingness, as a 
tule, to feed on meat, make it a very suitable inmate of the 
Vivarium. When full-grown it is about a foot in length. It 
comes from Madeira and the Canary Islands. 
The Black-spotted Lizard (Algiroides nigropunctatus). ‘The 
Lizards. of this genus have their dorsal scales much larger and 
more strongly keeled than those of the former genus. This 
Lizard, also known as Lacerta nigropunctata, Dum. and Bibr., 
is about 8in. long, and has, for its size, a large and depressed 
head. The rostral scale touches the nostril. The collar, which 
is well-marked, has a serrated edge. The scales of the back 
are very large, strongly keeled, and imbricate. The hind 
leg is about as long as the body, and the tail is about twice 
as long as the head and body. The upper part of the body is 
olive-green, generally spotted with black (hence the specific 
name): the lower surfaces are a greenish or bluish-white. This 
Lizard is a native of the Ionian Islands. 
The Spanish Sand Lizard (Psammodromus hispanicus) is very 
common in Spain, and is about 6in. in length. The scales on 
the back are very large, strongly keeled, and tiled; the scales on 
the tail are also strongly keeled and tiled and arranged in rings. 
The tail is cylindrical and nearly twice as long as the head and 
body. The collar is only feebly marked; but in other species of
