long time being of a colour similar to that of the Lizard when it 
was first born. Lacerta wvipara is found in England, Scotland, 
and even Ireland, and Northern and Central Europe and Northern 
Asia. The average length of the species is 6in. 
The Wall Lizard (Lacerta muralis) is a very pretty and 
graceful Reptile, and exceedingly active. At first sight it 
seems much like the viviparous Lizard. There are, however, 
several important differences between the two species. The 
Wall Lizard has a longer head and tail than its near relative. 
The tail of the former, gradually tapering to a very fine point, is 
more elegant in shape, as that of the latter retains almost the 
same thickness for nearly the first half of its length. The Wall 
Lizard has a series of granules between the two scales immediate- 
ly over each eye known as the supraocular and supraciliary scales ; 
these granules are not found on the head of Z. vivipara. The 
scales on the temple of the former Lizard are much smaller than 
those of the latter: and LZ. muralis has generally twice as many 
femoral pores as the Common Lizard, and is longer than its 
relative, sometimes reaching a length of 9in. There are a great 
many varieties of this Lizard. Mr. Boulenger describes the 
colours of the typical form in the following words: “ Upper parts 
brown or greyish, variously spotted, marbled or streaked with 
black ; lower surfaces white, yellow, pink, or red, uniform, or 
(in males) more or less largely spotted with black ; outer ventrals 
frequently blue.”’ 
According to the same authority the variety tiliguerta has the 
“upper parts green or greenish, uniform, or spotted or marbled 
with black, or with blackish and whitish streaks along the back ; 
usually a large black ocellus with blue centre above the axilla 
(armpit) ; lower surfaces usually immaculate.” 
The variety jfilfolensis is “ black; back with round greenish 
spots ; throat and sides of belly with blue spots.”’ Found on the 
Filfola Rock, near Malta. 
The variety Jilfordii is ‘“ blackish-brown above, sapphire-blue 
inferiorly.”’ In addition to the above varieties there are several 
more, but space will not admit of their description. 
The Lizard has a very wide range, being found nearly all over 
Europe and Western Asia,
