452 TEN YEAES IN SWEDEN. 



or covered. This sub-order can be divided into two families, 

 Sauri Proprii and Ophiosauri. 



Fam. 1. SAURI PEOPEII. 



Body not so slender as in the Ophiosauri' furnished 

 with four feet, each of which has five toes, armed with 

 claws. Ears apparent. 



Gen. Lacerta } L. 



Head covered with plates ; upper part of the body with 

 scales; underneath with transverse four-cornered plates, 

 in six or eight broad rows ; two rows of teeth on the 

 palate ; eyelids present ; tongue warty. 



2. LACERTA AGILIS, L. Sand Odla. The Sand Lizard. 



This is the largest of all the Scandinavian lizards ; at- 

 tains a length of 10 in., of which the head will be about 

 6 1. ; neck 5 1. ; body 2 in. 3 1. ; tail 5 in. ; colour grey- 

 brown, with a brown band along the back ; covered with 

 blackish and white figures and spots ; palate with two 

 rows of teeth. 



I cannot agree with Professor Bell when he says that 

 Linnaeus clearly meant the present species to be the type 

 of Lacerta Agilis in Sweden. Certainly Linne, in his 

 " Fauna Suecica," notices two species, the one the Lacerta 

 vulgaris or vivipara, Kay., and under the L. Agilis he gives us 

 three forms, and it is certain that his variety 7 which he 

 calls "Lacerta dor so punctis albis duplici serie," belongs 

 to the Lacerta vivipara, because he distinctly says, "Habitat 

 ad templum lockmock, Luleusis, Lapland/' Now it is quite 

 clear that the true sand lizard was never met with so far 

 north, not even so far up as Upsala (as Linngeus says). It 

 is, in fact, in my opinion, rare even in the south, for when 

 I was collecting in Scania, I rarely obtained a specimen, 

 whereas on the opposite coast of Denmark, around Helsingor, 

 it was extremely common on all the low sandy grassy 

 banks, and I could obtain any number of specimens in 

 a day. It is distributed over the middle and south of 

 Sweden generally, I believe, but is nowhere very common,
