similar in its markings to certain males of the var. (ivadrilitipufa, that 

 it might easily he mistaken for that variety were it not for tin- flatter 

 head ; and it is noteworthy that its exceptionally small scales (65 

 across the middle of the body) is a further approximation to the 

 Corsican-Sardinian form. Camerano has already pointed out that 

 some of the Ligurian' specimens examined by him, with a much 

 flattened head and reticulate markings, are suggestive of the var. 

 heclriagx from the mountains of Corsica. On the other hand, Bedriaga 

 regarded the var. brueygemanni as forming the passage from the typical 

 form to his var. neapolitana {cavipestris + alhiventrU) , and it is a fact 

 that some specimens approach the var. alblvenfris.
