white eyes may become irregular or even form cross-bands, as is fre- 

 quently the case in L. ocellata. Secondly, the dark markings may 

 subsist alone to form the three longitudinal bands which are often 

 present in L. civipara and L. mnralis. Thirdly, the dorsal markings 

 entirely disappear (var. rubra), or the lateral band and the ocelli are 

 replaced, as in some males, by a uniform puncticulation, or even the 

 lateral markings are lost (var. immaciUata) . Black specimens appear as 

 the result of an invasion of the ground-colour by the lilack markings.

Contrary to the rule in many species of this genus, but in agreement 

 with the majority of lower Vertebrates, females are, on an average, 

 larger than males. 



A young at birth measures 26 millim. from snout to vent, tail 29.
