154 Lacertidie. 



approaching L. agilis and L. muralis, var. eanvpestris respectively ; 

 masseteric and tympanic shields usually distinct, the former sometimes 

 very large and in contact with the upper temporals, of which there are 

 usually 2 or 3.* Pterygoid teeth nearly always present. 



19 to 28 scales and granules in a straight line between the symphysis 

 of the chin-shields and the median collar-plate; gular fold always 

 well marked. Collar formed of 8 to 12 plates (usually 9 to 11), the 

 edge more or less distinctly serrated. 



Scales on body juxtaposed, oval or oval- hexagonal, very small and 

 more or less diagonally keeled on the back, larger and smooth or very 

 feebly keeled towards the ventrals. Exceptionally the scales on the 

 back may be almost perfectly round granules, with a feeble straight 

 keelt or even almost without a trace of a keel.J In a male from 

 Eakos, Hungary, which has very strongly keeled dorsal scales, and in 

 another from Corfu, the scales on the flanks, right down to the ventral 

 plates, show a feeble yet distinct keel. The number of scales across 

 the body varies from 42 to 62 § ; on the flanks, 3 or alternately 2 and 

 3 series of scales correspond to a ventral plate; 36 to 50 scales, in the 

 middle of the back, correspond to the length of the head. Ventral 

 plates in 6, exceptionally 8|| longitudinal and 25 to 32 transverse 

 series (25 to 29 in males, 25 to 32 in females) ; the plates of the 

 second series from the median line usually much broader than the 

 others. Preanal plate moderately large or rather small, with 2 or 3 

 semicircles of small plates or scales, one or two of the median plates 

 of the inner semicircle sometimes considerably enlarged. 



Scales on upper surface of tibia usually smaller than dorsals, more 

 or less distinctly keeled. 19 to 29 lamellar scales under the fourth 

 toe. Femoral pores 14 to 20 (usually 15 to 19) in the typical form,! 

 15 to 25 (usually 18 to 21) in the specimens from Greece and the 

 Ionian Islands (var. ionica). 



Caudal scales oblique, more or less obtusely pointed behind, the 

 upper strongly keeled, the lower smooth or feebly keeled ; the whorls 

 subequal in length; 30 to 37 scales in the fourth or fifth whorl behind 

 the postanal granules. 



This species has been divided into two, L. taui-ica, from the countries 



* Only one in a male from Tzabadta and in two from Budapest. 



t Females from Crimea and Tzabadka. 



J Female from Eutshuk. 



§ 42 is exceptional and occurs only in one female from L. Stymphalos, two 

 males from the same locality having 50 and 55 respectively. 



II In a male from Greci, in a male from Constantinople, in a female from 

 Bazias, and in a male from Tyrias-Mykena.
