742 MR. G, A. BOULENGER ON THE SPECIES OF [June 21, 



spotted with black ; a few black spots on the back ; sides and limbs 

 closely spotted with black. Females and young with more or less 

 defined light spots, surrounded by a dark network. Lower surface 

 greenish ; throat more or less spotted with black : males with one 

 or two black dots on each ventral shield, as in L. stirpium ; these 

 dots generally entirely absent in females. The spots on the lower 

 surface and on the head are never met with in L. Icevis.

Lacerta L/EVIs, Gray, Ann. N. H. i. (1838), p. 229, and Cat. 

 p. 31 ; Giinth. P. Z. S. '\SCA, p. 488. 



This Lizard has been considered equivalent to L. agilis {L. stir- 

 pium) by Bedriaga and Boettger ; the reason which induced them 

 to take this view, I do not know. The type specimen is a female, 

 bleached; in proportions and pholidosis it agrees perfectly with the 

 recently described Podarcis judaica, Camerano^. The specimens 

 from Palestine referred to by Giinther are in good state, and the 

 coloration agrees with that of L. judaica as described by Camerano, 

 Bedriaga^ and Boettger'. Consequentlv the name judaica, Camcr. 

 (1877), must be altered to that of Icevis^ Gmy (1838). 



Lacerta strigata, Eichw., Gray, Cat. p. 32. 



L. viridis, L., Gunth. P. Z. S. 1864, p. 488. 



The British Museum possesses fine specimens of this form, which, 

 in general appearance seems quite different from L. viridis. How- 

 ever, no important structural difference being noticeable, I think 

 L. strigata must be considered merely a variety of L. viridis. 



At present, 1 7 species of Lacerta appear to be perfectly charac- 

 terized. In the following synopsis, I have endeavoured to facilitate 

 their determination. I have used as a character the number of 

 upper labials in front of the infraocular ; but it must be observed that 

 there may be accidentally one labial more or less. These irregularities 

 occur very rarely, and generally only on one side ; and as, in this dif- 

 ficult group, several specimens are, as a rule, required to name a 

 lizard properly, I think this character will be of great help in dis- 

 tinguishing the species.
