310 Lacertidae. 



longest ; a series of granules, very rarely two, between the supra- 

 oculars and tlie superclliaries. Eostral as deep as broad or a little 

 broader than deep (not more than IJ times), narrower beneath than 

 above ; three nasals, the lower in contact with the 2 or 3 first upper 

 labials and usually with the rostral * ; anterior loreal as long as deep 

 or deeper than long, very rarely a little longer than deep t or absent,J 

 shorter than the second ; subocular keeled below the eye, bordering 

 the mouth, sometimes broadly, sometimes narrowly, between the 5th 

 and 6th or 6th and 7tli, i-arely 7th and 8th, upper labials. Temporal 

 scales granular, smooth ; tympanic shield present ; no auricular 

 deuticulation. Lower eyelid opaque or semitransparent, covered with 

 small scales. 



5 pairs of chin-shields, rarely 4 or 6, the 3, rarely 2, anterior in 

 contact in the middle. 22 to 32 § gular scales in a straight line 

 between the symphysis of the chin-shields and the median collar- 

 plate; gular fold usually distinct. Collar curved, free, serrated, 

 composed of 9 to 14 plates. 



Scales granular, smooth, 49 to 63 across the middle of the body. 

 Ventral plates as long as broad, or a little broader than long, or a 

 little longer than broad, forming more or less regular oblique longi- 

 tudinal series or tessellated ; in 28 to 36 slightly angular transverse 

 series, the longest of which contain 14 or 16, rarely 12, plates. Pre- 

 anal region covered with small irregular plates, sometimes with an 

 enlarged median plate posteriorly. 



Upper surface of arm with rhombic smooth scales which are larger 

 than the largest gulars. Scales on upper surface of tibia similar to 

 the dorsals, but smaller; lower surface with one row of very large 

 and one or two of small plates. 17 to 23 || femoral pores on each 

 side, the two series narrowly separated or meeting in the middle. 

 Subdigital lamellae uuicarinate, rarely tricarinate, 19 to 25 under the 

 fourth toe. 



Upper caudal scales oblique, truncate or obtusely pointed, more 

 or less strongly and diagonally keeled, lower, at the base, smooth ; 

 24 to 38 scales in the fourth or fifth whorl behind the postanal 

 granules. 



* Narrowly in 24 specimens, extensively in 3, separated in 9. 



t In one male from Novo Alexandrovsk. I cannot understand how Sohreiber 

 can have mentioned the elongate shape of the anterior loreal as a character 

 distinguishing E. velox from E. arguta. 



J In a young from the Caucasus.
