In habit similar to Lacerta vivipara. Usually two superposed 

 postnasals, the lower of which may form a suture with the rostral ; 

 supraoculars in contact with the siipraciliaries, first largest and 

 separated from the loreal by a very small shield, third smallest ; 

 interparietal much longer than broad ; occipital small ; two enlarged 

 su^jratemporal shields border the parietal ; temple with irregular 

 smooth shields ; an enlarged tympanic shield ; subocular bordering 

 the lip, between the fourth and fifth upper labials. Gular scales 

 large and strongly imbricate ; the two or three anterior pairs of 

 chin-shields in contact. 24 to 30 scales, ventrals included, round 

 the middle of the body. Ventrals strongly imbricate, in six lon- 

 gitudinal series, those of the median and outer series scarcely 

 broader than long, the others much broader than long ; they form 

 22 to 26 transverse series. A large median praeanal plate, bor- 

 dered by one or two semicircles of small plates. The adpressed 

 hind limb does not reach the axilla. 4 to 7 femoral pores on 

 each side. Tail about twice as long as head and body. Olive- 

 brown above, with two dark and two light longitudinal streaks ou
