puporciliavies, first or second longest, the suture between tlie first and second usually 

 ol)lique, sometimes vertical ; an incomplete scries of f^ranules between the supra- 

 oculars and the superciliaries, the first superciliary beinjif constantly in contact with 

 the second supraocular, the granules sometimes minute or reduced to 2 to o *. 



Rostral entering the nostril, often largely f; postnasal single J ; anterior loreal 

 much shorter than second ; 4 upper labials anterior to the subocular §, the lower 

 border of which is shorter ihau the upper. Scutellation of the temple very variable, 

 the two extremes (text-fig. 9) approaching L. mjilis and L. iituraUs, var. campestris, 

 respectively; masseteric and tympanic shields usually distinct, the former sometimes 

 very large and in contact with tlie upper temporals, of wliich there are usually

 one [a) from Sebastopol, the other [h) from Cephalonia, but these figures are not 

 meant to convey the impression that the serration is generally stronger in the typical 

 form than in tlie var. ionicn. 



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,

t I have observed only two exceptions (female from Szabadka and female from Corfu), in which the rostral 

 is narrowly separated from the nostril.
