The proportions are the same as in the typical form, but the length of the head in 

 males is contained S^ to 4^ times iu the length to vent and the pileus is 2 to "2\ times 

 as long as broad. Tail sometimes up to If times length of head and 4iody. 



Nearly always two superposed postnasals, followed by one or, more frequently, two 

 superposed anterior loreals, or anterior loreal absent*. The suture between the nasals 

 usually longer, i to f the- length of tlie frontonasal, which is usually as broad as or a 

 little broader than the internarial space f. First supraocular sometimes very small, or 

 even almost reduced to a granule, and not touching the second loreal %. Superciliaries 

 sometimes reduced to two or three ^. Temporal lepidosis very variable, sometimes 

 consisting of a few large shields, sometimes of small, almost granular scales || ; 

 tympanic often indistinct ; the two upper temporals, of which the first is nearly 

 always much longer than the second, usually less broad, sometimes but narrowly 

 in contact with the fourth supraocular, or even not touching that shield ^. Occipital 

 small or very small, sometimes minute. 5 anterior upper labials is very exceptional. 



15 to 23 (usually 17 to 20) gular scales. 8 to 13 (usually 9 to 12) plates in the collar. 

 34 to 52 scales across the middle of the body, usually 40 to 49. In some specimens the 

 scales on the vertebral region are much narrower and abruptly differentiated from the 



* Out of 150 cases, 2 postnasals and 2 anterior loreals occur 61 times ; 2 postnasals and 1 anterior 

 loreal 36 times: 2 postnasals and no anterior loreal 39 times; 1 postnasal and 2 anterior loreals 14 times; 

 the upper or the lower part of the anterior loreal sometimes fused with one of the postnasals (this is expressed 

 in the table b_v \). Specimens with these and other head-shields abnormally multiplied b)- division have 

 been figured by Cugunov, I. c. 



t Narrower in specimens from Moscow, Tomsk, !Novorossik, Urkatch, Ala Tau, Lepsinskaja Staniza, 

 Altai; in contact with both postnasal and anterior loreal in 5 specimens (lelenowka, Vladikaukas, Lepsins- 

 kaja Staniza, 11. Kunge-ss). 



J In 14 specimens. It is curious to read that Bedriaga (I. c. p. 135) regarded this condition as more 

 characteristic of L. viridis. 



§ Specimens from 11. Kungess. A female from Vladikaukas is exceptional in having a series of S-IO 

 granules between the superciliaries and the supraoculars. According to Uedriaga, a scries of granules nmy 

 be present iu specimens from the Volga district. Otherwise, I have never found more than one or two 

 granules.
