Various synonyms referable only to some European form or phase

Rana temporaria, as compared with R. japonica, is a much more 

 short-legged and short-snouted species with the dorso-lateral folds 

 apparently wider. Altogether it is larger and stouter, the body 

 especially between head and pelvis being relatively longer. Thus in 

 my specimens of R. temporaria from Yezo, the length of the foot, 

 measured from inner metatarsal tubercle to tip of longest toes, exactly 

 equals one-half the distance from anterior border of eye to vent, 

 while in R. japonica the length of the foot, similarly measured, is 

 about two-thirds the same distance. 



I have compared our three Japanese specimens from Yezo with 

 specimens of corresponding sex and size from Norway (for instance, 

 No. 25339, Bergen) and find no tangible differences. The web

between the toes is perhaps a trifle more excised, and the inner meta- 

 tarsal tubercle a trifle stronger, but these differences are clearly 

 within the range of individual variation. 



Description. —Adult female; U.S.N.M. No. 23440; Sapporo, Yezo; 

 S. Nozawa, collector (figs. 90-93). Vomerine teeth in two slightly 

 oblique groups, the anterior border of which extends forward slightly 

 beyond a line through the posterior border of the choanse; snout 

 short, rounded, the distance from orbit to tip of snout equaling the 

 distance between black stripes at anterior border of orbit; nostrils 

 nearer the tip of snout than the eye; interorbital space as wide as the 

 upper eyelid and a little narrower than distance between the nostrils; 

 tympanum vertically oval, its greatest diameter about three-fourths 

 the diameter of the eye; distance of tympanum from eye less than
