the two central and the two outer are smaller than the re- 

 maining two ; the pre-anal plate is large, four- or five-sided, 

 and bordered by a row of from seven to nine plates, which 

 are tiled upon the central plate; the fore-legs scarcely 

 reach to the front of the eyes ; the hind-legs, laid along 

 the sides, do not extend much beyond half of their length ; 

 femoral pores eight to fifteen on each side, in flat triangular 

 scales. The colour of the back is brown or brickdust, 

 sometimes spotted with black; the sides greenish in the 

 male, tawny brown in the female ; belly white, or white 

 spotted with black, but many variations of colour will be 

 met with. 



Entire length of a large specimen, 8-f inches ; tail, 5

The Sandy Lizard is found over nearly the whole of 

 Europe, if we except the extreme Worth. It is rare in 

 Belgium. Is found only in the Northern parts of Italy, 

 and in certain districts of the South of England. Is not 

 common in the Southern Provinces of Prance, according to 

 Crespon, but abounds in Germany, Switzerland, Poland, 

 Northern Russia, and in Siberia, and generally throughout 

 Central Europe ; everywhere, however, avoiding mountains, 

 in which respect its habits are the reverse of the L. vivvpara.
