The adult female (U.S.N.M. No. 23548, same locality, date, and col- 

 lector) is essentially like the male described above, except that the 

 botly is broader and the dorso-lateral ritlges conse(iuently farther 

 apart, the fore legs less robust, and the swelling on the first finger, 

 which is characteristic of the male sex, absent ; the web between the 

 toes is also somewhat more excised. The color is more reddish brown, 

 with scarcely any black spots on the back except those marking the 

 inverted V on the shoulder. Both upper and lower lips are blotched 

 with dark brown. 



The young specimens are mostly perfectly smooth above, ^\dthout 

 any tubercles between the dorso-lateral folds. 



Variation. — This species offers a great amount of individual varia- 

 tion. The most variable character is the length of the hind legs, for, 

 while in most specimens the tibio-tarsal articulation reaches just 

 beyond the snout, in a few it falls short, while in others it extends 

 considerably farther. The longest hind legs in our collection are pos- 

 sessed by an adult female (No. 31828) collected by Dr. Hugh M. Smith 

 at Yamagawa, Satsuma, Kiusiu, but other specimens in the same lot 

 (for instance. No. 31829) can be exactly matched in every respect by 

 the general run of specimens of corresponding size from central Japan 

 (for instance, No. 34465). The situation of the nostrils relative to the 

 tip of the snout and the correlated length and pointedness of the snout 

 also vary considerably, but in no case have I been able to trace any 

 correlation with length of hind legs or geographic distri))ution. The 

 color varies greatly ; the ground color with regard to the amount and 

 tinge of the brownish or yellowisli admixture, the dark spots and 

 bands with regard to intensity and number. Spots are fre([uently 

 absent, and the male described is rather unusually dotted with black 

 above. The underside is not always uniform white; in many speci- 

 mens there are brown spots and mottlings on throat or even on chest, 

 but no connection with distribution or structural characters can be 

 discovered. 



There is a young specimen in the collection of the Philadelphia 

 Academy of Sciences (No. 15257), collected by Dr. W. H. Jones at 

 Chemulpo, Korea, August, 1890, which appears even more slender 

 and long-snouted than the Japanese specimens, but this niay be due
