 Genus SALAMANDRELLA ^ Dybowski.

This genus is not represented in Japanese territory, unless it should 

 be found on some of the northern Kuril islands, such as Paramushir 

 or in south Sakhalin. So far as known it occurs only in south- 

 eastern Siberia from Lake Baikal to Ussuri and also in southern 

 Kamchatka. 



SalamandrcUa differs from Hynobius chiefly in the complete ab- 

 sence of a fifth toe. In view of the rudimentary state of this member 

 in several species of the latter genus, and its occasional total sup- 

 pression in individuals, it is a great question whether the genus can be 

 maintained in the future.
