HERPETOLOGY OF JAPAN: 



41 



Variation. — The differences in dentition and proportions of the tail 

 have been alluded to above (pp. 38-39). The coloration is fairly 

 uniform throughout the series, except that in the lot received from 

 Dr. Vladimir Tiishoff" the median dorsal area is of a frosted silvery 

 gray rather than tawn^^ 



Habitat. — Extends from the Ural Mountains in the west to the Ussuri 

 country and Kamchatka in the east, north to Verkhoyansk, Siberia, 

 and south into the Chinese province of Sze-chuan. 



Dybowski collected the types at the southwest corner of Lake 

 Baikal, while von Schrenck brought home specimens from the Shilka, 

 from Ussuri, and also from Lake Baikal. Boulenger has recorded 

 specimens collected by Mr. Doerries at Khabarovka. Dieckmann, in 

 1894, also obtained it at the latter place and near Vladivostok, the 

 specimens being in the Hamburg Museum (Nos. 865-866). Sabaneef, 

 in 1872, recorded it from Yekaterinburg, on the east slope of the L^ral 

 Mountains, where he found it to be common, and Shitkov, in 1895, 

 studied its reproduction and development there. 



The Kamchatkan specimens were at one time considered a distinct 

 species. The types were collected by Wossnessensky at the Javina 

 River, on the west coast, not far from Cape Lopatka, the southern end 

 of the peninsula. I myself obtained specimens from the neighbor- 

 hood of Petropaulski, on the eastern shore, while von Ditmar records 

 the species from the interior, from the valley of Kamchatka, near 

 Tolbatcha, and also from the Uson volcano, near Lake Kronotskoi.*^ 



According to Nikolski (1905) this salamander has been collected in 

 Sakhalin by Doctor wSaprunenko in 1890, the specimen being in the 

 St. Petersburg Museum (No. 1941).
