VAEIETIES or THE WALL-LIZAED. 153 



and smooth dorsal scales and nearly smooth caudals are found in so many typical 

 L. miiralis and closely related varieties, that very little importance attaches to such a 

 character. Specimens with smooth and keeled dorsal scales are placed in the same 

 species by Mehely when dealing with L. saxicola (1909, p. 491). 



9. The high number of gular scales. — 26 to 39 in L. hedriagoe, 24 to 32 in L. insu- 

 lanica, 22 to 30 in i. Irueggemanni. 



10. The more feelle gular /oM.— Better marked in a large male L. ledriagoe from 

 Tinozzo, and in another from Bastelica than in some of the lizards from Pianosa. 



11. The same number of transverse series of ventral plates in the tivo sexes. — See 

 what I have to say of the Maltese lizards, p. 160. 



12. The greater number of rows of scales on the lower surface of the thigh. — I count 

 5 to 8 rows between the large shields and the femoral pores in L. bedriagm, 5 or 6 in 

 L. insulanica. 



13. The greater number of femoral pores. — 19 to 31 in L. bedriag(B, 19 to 26 in 

 L. insulanica. 



As regards the scaling, a greater difference exists between a typical L. muralis from 

 Lower Austria (A) and L. insulanica than between L. insulanica (B) and L. bedriagce 

 (C), as shown by the numbers of scales across the body (a), of femoral pores [b), and 

 of subdigital lamellse under the fourth toe {c) : — 



A. a. 42-53. b. 13-19. c. 22-25. 



B. „ 60-74. „ 19-26. „ 26-33. 



C. „ 58-78. „ 19-31. „ 26-31. 



14. The reticulated livery of the young and the absence of secondary sexual characters 

 in the markings. — These are features which are likewise characteristic of L. insulanica. 

 As the latter point is one on which Mehely lays great stress in his classification of the 

 M^'all-Lizards, I think no better example could be adduced to show the fallacy of his 

 conclusions than that offered by this Pianosa lizard, which, in its habitat between Elba 

 and Corsica, appears to constitute a geographical link between the Elba lizards of the 

 var. brueggemanni and the var. bedriagm, isolated on the mountains of Corsica. I do 

 not suppose any one who has devoted some study to these lizards could think of 

 regarding the Filfola Rock lizard as more than a variety derived from the smaller form 

 living on Malta; and yet the latter shows as strong a sexual coloration-dimorphism 

 as the typical L. muralis, whilst the former is, in this respect, in the same condition as 

 L. bedriagce.

Signor Meloni has sent me 34 specimens from Latzobe, Urzulei-Ogliastra Mountains, 

 altitude 1080 m., which vary much in markings. Many of the males have large black
