Lacerta. 183 



This lizard shows much variation in the coloration, and some of the 

 variations appear to be fixed in certain localities. 



A. Grreeu or olive-brown above, with brown vertebral and lateral 

 bands spotted with black ; six li<^ht, pale green or white streaks, viz. 

 on each side, one borderinij;' the vertebral band, one from the super- 

 ciliary border to the tail, along which it extends for some distance, 

 and one from below the eye to the side of the tail, passing through 

 the ear, above the fore limb, and through the hind limb. Lower 

 parts white, unspotted, or with a series of black dots on the outer row 

 of ventrals. Specimens thus coloured (var. striata, Werner) are 

 hardly distinguishable from the var. campestris, but, according to 

 Werner, the head is, as a rule, more depressed (" eher platy-als 

 pyramidocephal "'). The young is olive-brown, with six very sharply 

 defined white lines. Most of the specimens referable to Werner's var, 

 striata are females, but some males agree with it, at least in having 

 the six light lines. Specimens from Bosnia and Herzegovina are in 

 the British Museum collection. The types of var. striata are from 

 Fiume, Spalato, Ragusa, Bol. and Gelsa. Strongly striated specimens 

 from Northern G-reece have been named var. livadiaca by Werner. 



B. Specimens in which the back is green (olive-green to bluish- 

 green) with black spots as in the preceding, but the white lines 

 reduced to the dorsal-lateral, have been named var. fiumana by 

 Werner ; they are mostly males, with bright orange-red belly and blue 

 spots on the outer ventral shields. From Fiume, Cherso, Veglia, 

 Brazza, Lesina. Specimens from the Istrian Karst and others from 

 Bosnia and Herzegovina are in the British Museum. Males from 

 Fiume, types from Dr. Werner's collection, have the belly dotted all 

 over with black. A blue, black-edged ocellus sometimes present above 

 the shoulder, 



c. Uniform green, dark green, or reddish brown specimens without 

 any markings (var. imitans Werner), similar in this respect to the 

 Italian individuals named var. modesta, but with the thi'oat and breast 

 or the whole of the lower parts orange or red in the males at least, 

 occur in Istria, Dalmatia, and Herzegovina, and on the islands of 

 Lussin, Cherso, Veglia, Bua, Solta, Brazza, Lesina, Curzola, and 

 Meleda. Some individuals, however, show more or less distinct traces 

 of the light dorsolateral streak, whilst others with a few black spots 

 on the sides establish the connexion with the colour-variations 

 descril»ed above. Some male specimens from Istria. which I received 

 alive, were of a bright grass-green on the back, of a golden colour on 

 the head, sides, and limbs, and of a bright orange beneath.
