No specimen of this form is available for detailed description, 

 which, moreover, seems to be unnecessary, as the chief difference is 

 believed to consist in the greater number of ventrals and greater 

 average of scale rows and supralabials, features previously discussed 

 (pp. 450-456). 



Habitat. — This form has a wide distribution from the Gulf of Tar- 

 tarv and the Sea of Japan, in the East, through southern Siberia 

 and Mongolia to the Government of Tomsk and eastern Turkestan, 

 in the West consequently extending over more than 50 degrees of 

 longitude. At its eastern boundary it has been found as far north 

 as Cape Tyr (above Nikolayevsk), on the Amur, and Decasties Bay, 

 on the Gulf of Tartary. On the west shore of the Sea of Japan it 

 goes southward at least to Possiet Bay. It seems to be common all 

 over the Ussuri and Amur country, as well as along the coast, where, 

 in addition to the localities already mentioned, it has been collected 

 at Vladivostok and Olga Bay.
