HERPETOLOGY OF JAPAN. 53 



gray, with irregular obscure dusky spots and dusky cross-markings 

 on the Hmbs; a pale sage-green spot of irregular outlines across the 

 back between the fore legs and two smaller ones, still more indefinite 

 on each side of the back about the middle; a pale longitudinal stripe 

 on the tip of the snout from the level of the nostrils to the lip ; lips 

 dusky; underside pale buff (red in life), with numerous blackish, 

 sharply defined, irregular spots; palms buff (red), separated from the 

 similarly colored under surface of the fore arm by a black wristband; 

 a large buff (red) spot on the inner side of the plantar surface, involving 

 the entire first toe, below and above, and continuous with the sim- 

 ilarly colored patch on the inner side of the tarsus; tips of all the 

 digits abruptly and bright buff (red) above and below.

Sexual variation. — The males of this species during the breeding 

 season possess groups of blackish horny excrescences on the inner 

 side of fore arm, palmar tubercle and first, second, and third fingers 

 exactly as in Bombina salsa; but, unlike the latter, there are none on 

 the posterior extremities. In the female the fingers are longer and 

 slenderer, especially the outer one. The dorsal spines and asperities 

 are smaller. 



Color variation. — In the series before me there is very little devia- 

 tion from the coloration of the underside as described above. In two 

 specimens, Nos. 17527 and 17530, the blackish markings are larger, 

 especially in the latter, in which the underside may be described as 

 black with buff (red) spots; in both, the plantar light patch is sepa- 

 rated from the tarsal patch by a narrow black bridge, in No. 17530 

 only on one foot, however. The upper surface is considerably more 

 olive in some specimens and the dusky spots and markings above 

 much better defined and darker. 



Ilahitat. — The eastern bell-toad is confined to northeastern China, 

 Korea, and the Ussuri country. Specimens from all of these localities 

 are in the British jMuseum. The U. S. National Museum possesses 

 nine specimens collected in 1885 by P. L. Jouy near Fusan, Korea. 

 Pleske's specimens from Vladivostok are in the Academy Museum in 

 St. Petersburg, and the Hamburg JMuseum also has it from the same 

 locality (No. 862), collected by Dieckmann in 1894. In the St. 

 Petersburg Museum there are also specimens collected by Poljakow 

 at the Novgorodski Port, Possiet Bay,
