South-eastern Europe, in South-western Asia, and in 

 North Africa, and lias more than once given rise to 

 erroneous statements as to the distribution of B. 

 calamita. It also seems as if this line were occasionally 

 absent in the latter species only in those countries 

 where B. viridis does not exist. In Eastern Asia, 

 where neither B. viridis nor B. calamita,, nor any other 

 species with such a line occurs, the same character is 

 assumed by some specimens of B. vulgaris, which thus 

 take the place of their absent congeners so far as this 

 conspicuous marking is concerned. 



Male distinguished by much stronger fore limbs, a 

 large callosity on the inner side of the first finger, 

 fuller webs between the toes, a small, feebly pigmented 

 internal vocal sac, and, during the breeding season, 

 blackish horny excrescences forming bands on the 

 inner-upper side of the three inner fingers and the 

 inner carpal tubercle ; the extent of this band on the 

 inner finder is much greater than in the two other 

 species of this genus, and is borne on a pad having 

 some resemblance to that of Rana temporaria.
