52 Lacertidx. 



Lacerta agilis, var. cJiersonensis, Bouleng. Tr. Zool. Soc, xxi, 1916, 

 p. 27, pi. ii, figs. 1, 2. 



As pointed out by Kiritzescu, the Roumauiau specimens from the 

 Carpathian district do not differ in any respect from the typical 

 form, whilst the others, which I refer to the var. chersonensis, approach 

 the var. exigua and also L. viridis. 



The head is a little smaller than in the typical form, being con- 

 tained 4 to 4| times in length to vent in males. One postnasal 

 followed by one anterior loreal, as in the var. spinalis, is frequent 

 (18 cases out of 38), but there are often two postnasals, followed by 

 one or two anterior loreals ; one postnasal and two anterior loreals,^ 

 forming a triangle, as in the typical form, is the exception (7 cases) ;. 

 postnasal never in contact with the frontonasal. 



As in the var. exigua the length of the suture between the nasals 

 varies from one-third to two-thirds the length of the frontonasal,, 

 which is often as broad as the interuarial space. Frontal 1^ to 2 

 times as long as broad, sometimes not broader than the major supra- 

 oculars. Occipital usually shorter than the interparietal. Sub- 

 ocular much narrower beneath than above. Shields covering the 

 temple smaller than the average in the typical ionn ; tympanic usually 

 indistinct. 



Scales a little smaller, on an average, than in the typical form,, 

 more as in var. exigua (17 to 21 along the throat, 38 to 46 across the 

 bodv), those on the vertebral area much narrower than the dorso- 

 laterals, as in the typical form. Ventrals usually in 6 longitudinal 

 series. Preanal plate large, as in the typical form. Femoral pores 

 more numerous (14 to 18, rarely 13), as in var. exigua. 



According to Kiritzescu, the tail is sometimes nearly twice as long- 

 as head and body. 



The markings are very variable. Some specimens have a dark brown 

 vertebral band, measuring l to f the width of the pileus, bearing 

 black spots, in one or two series or irregular, and bordered on each 

 side by a more or less distinct light line ; that this light line is the 

 superciliary streak of Mchely is shown by its condition in one male 

 specimen from Zorleni, Roumania, in which, after having followed the 

 outer border of the occiput, it suddenly turns at an angle towards 

 the middle of the nape, as is also the case in certain specimens of the 

 typical form; the dai-k vertebral band is sometimes divided by a 

 continuous or interrupted light median streak ; the sides show two or 

 three lateral series of black and white ocellar spots, of which the 

 upper are the largest, as in the typical form.
