Dumeril and Bibron b assert that Schlegel's identification of Hout- 

 tU3"n's Salamandra japonica as the present species is erroneous, but 

 to anyone who examines the original description and figures it must 

 be perfectly plain that Schlegel was correct. There can be abso- 

 lutely no doubt as to the identity of Houttuyn's species, and the 

 mistake of the authors of the Erpetologie Generale can only be 

 explained by their having confounded figures 2 and 3 on Houttuyn's 

 plate. The latter states that his specimen was collected by Thun- 

 berg in Japan. Thunberg himself described and figured the same 

 species under the same name, though apparently without knowing 

 Houttuyn's description, and he expressly gives the Hakone Moun- 

 tains (Fakonieberget) as the tj^e-locality, consequenth^ it is in all 

 probability also the locality where he obtained the specimen Houttuyn 

 described.
