I will first give a description of the widely distributed form, from 

 Istria, Croatia, Dalmatia, Bosnia, Herzegovina, Montenegro, Albania 

 and Northern Greece, and various islands on the coast of Istria and 

 Dalmatia, to which the above synonymy pertains, and then refer to the 

 insular forms which are evidently derived from it, and which have been 

 described as vars. lissana, melisellensis, and galvagnii. 



The typical var. fiumana, which in size and coloration may be 

 regarded as connecting the var. campestris with the forma typica, is 

 hardly to be distinguished from the former, especially if compared with 

 specimens from Piedmont, where the var. campestris does not reach so- 

 large a size as elsewhere. It is very easy to distinguish it from the 

 var. alliventris as occurring on the East coast of the Adriatic and on 

 several of its islands, but when Italian examples of the var. campestris 

 are taken into consideration, the gaps between the two extremes 

 disappear, and a continuous series connecting them is seen to exist. 

 This variety is also very closely related to the var. serpa and to 

 L. taurica, especially through the variety described by Lehrs as L. 

 ionica. Werner* has even hinted to the possible specific identity of 

 his L. fiumana with L. taurica and L. ionica, as had been suggested bv 

 Wiegmann,t who alluded to this lizard under the name of Podarcis 

 merremii, Eitz. (non Eisso), a nomen nudum under which L. fiumana 

 and other green varieties have often appeared in the past. However, 

 the presence of pterygoid teeth in L. tanricaX is, in my opinion, suflS-

X I have not found these teeth in any specimens of var. fiumana, any more 

 than in the typical form.
