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

 postnasals never in contact with the frontonasal. As in the var. exigiia 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 internarial space. Frontal U to 

 2 times as long as broad, sometimes not broader than the major supraoculars. 

 Occipital usually shorter than the interparietal. Subocular much narrower beneath 

 than above. Shields on the temple smaller than the average in the typical form ; 

 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

body), those on the vertebral area much narrower than the dorso-laterals, as in the 

 typical form. Ventrals usually in 6 longitudinal series. Prceanal plate large, as 

 iu 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 (PI. II. fig. 2) have a dark brown 

 vertebral band, measuring | to § the width of the pileus, bearing black spots, iu one 

 or two series or irregular, or bordered on each side by a more or less distinct light
