RANA. 341 



north-east and the central plateau.* It also occurs in 

 Jersey. It is rare and very local in Germany, the 

 localities whence it has been reported being Strass- 

 burg, Linz on the Rhine, the Kaiserstuhl between 

 Freiburg and the Rhine, Rothenburg on tbe Tauber, 

 Wi'irzburg and Traunstein in Bavaria, and about the 

 Zobten, south of Breslau, in Silesia. f In Switzer- 

 land it is known from' the cantons Geneva, Vaud, 

 Bern, Zurich, Valais. and Tessin ; in the Austro- 

 Hungarian Empire from Bohemia, Lower Austria, 

 Styria, the Tyrol, Illyria, Croatia, Dalmatia, Hungary, 

 and Transylvania. It appears to be pretty generally 

 distributed in Italy, and is on record from Modica, 

 Sicilv. It is further known from Bosnia, Albania, 

 and Greece. The only localities in Asia whence It. 

 agilis has been recorded are Lenkoran, on the south- 

 western coast of the Caspian Sea (Boettger), Suchum 

 Kale, Transcaspia, and Konkur Valley, S. of R. Hi 

 (Bedriaga), the two latter requiring confirmation. 

 Strauch has also referred some specimens obtained by 

 Przewalski in the Chinese province Ordos to what 

 he called the " agilis " form of R. temporaria, but these 

 will no doubt prove to belong to R.japonica,& species 

 which bears great resemblance to R. agilis. 



liana agilis is, on the whole, more a form of the 

 plain, being replaced in the mountains by R. tempo- 

 raria ; it is, however, known to reach an altitude of 

 4200 feet in the Alps of Switzerland, and to extend 

 pretty high up in the Tyrol and in Transylvania, as 

 well as in the Apennines. 



* Dealing with the mucilaginous capsules of frog ova, R. Florentin 

 (' Bull. Sci. France Belg.,' xx, 1897, p. 142), mentions having made ex- 

 periments at Nancy on Rana agilis, Thorn. As this statement might 

 result in French Lorraine being erroneously or prematurely added to 

 the habitat of tins species, I may point out that an error of identifica- 

 tion has been made, since had the author really seen eggs of R. agilis 

 he would not have attributed to frog spawn generally the floating power 

 which is possessed by that of R. temporaria alone among European 

 Batrachians. 



t I have examined a specimen from this locality.
