1. Length (in millimetres) from snout to vent. 2. Number of scales across middle of body. 

 3. Transverse series of ventral plates. 4. Number of plates in collar. 5. Number of scales and 

 granules between symphysis of chin-shields and median collar-plates. 6. Number of femoral 

 pores (on right and left sides, if differing) . 7. Number of supraciliary shields in contact with 

 second supraocular. 



In the female from Ferriere (PL XXV. fig. 2) and in the young male from Genoa 

 the snout is as short and as obtuse as in L. horvathi Mehely ; but this is also the case 

 in a few specimens from France. 



The dorsal scales are distinctly keeled, and 37 to 50 transverse series correspond to 

 the length of the head. The nasals usually form a very short median suture in the 

 Turin specimens, but 3 out of 13 have the rostral forming a suture with the 

 frontonasal J . Two specimens from Turin have 5 upper labials anterior to the sub- 

 ocular, and one from Portofino has only three on one side. 22 to 29 lamellar scales 

 under the fourth toe.

Professor Monticelli nas been so kind as to send me for examination all the 

 specimens of Lacerta muralis preserved in the Zoological Institute of the Naples 



1 Also in single specimens from Domo d'Cssola, Lanzo Valley, and Florence. Separation of tlie nasals 

 appears to be found in at least 20 per cent, of the specimens from south of the Alps.
