364 ME. G. A. BOTJLENGER ON THE VAEIETIES OF 



developed (separated from the parietal by 1 to 4 series of scales) in 10 specimens out 

 of 30, this plate in the others being just distinguishable or absent. In one specimen 

 from Seville the parietal is not in contact with the postocular. 



No specimen exceeds a length of 60 millim. from snout to vent, and females of 

 44 millim. are gravid. 



In their markings the very young (see text-fig. 4 c, p. 369) are quite similar to those of 

 the typical form from France, and a black vertebral streak (which I have never observed 

 in any of the specimens from North-Western and Central Spain and Portugal) is likewise 

 often present. The adults are pale grey or brown, and the blackish spots, if present, 

 are small ; a median series of black spots or traces of a blackish vertebral line are often 

 present ; ventral spots are absent or small and confined to the sides. One male specimen 

 from Valencia is exceptional in having the lower parts dotted all over with black. 



I append particulars of 12 specimens from Valencia, and of 2 from Seville.
