ART. 25 CHINESE AMPHIBIANS AND REPTILES STEJNEGER 11 



HYLA ARBOREA JAPONICA Guenther 



Herp. Japan, 1907, p. 76, pi. 9, figs. 1-3. 



The material of tree toads received since the publication of the 

 Herpetology of Japan is so insignificant that it throws very little 

 light, if any, on the question of the distinctness and distribution of 

 H. arborea japonica, imrnaculata, and stepheni. Nikolski has re- 

 cently added another subspecies, IJyla arborea ussuriensis, based 

 on a single specimen collected by Emeljanof in the neighborhood 

 of Tchernigovki Village, in the Coast Province." It is character- 

 ized by having the skin of the underside not granular but divided 

 up into a mosaic of large polygonal plates and by having the third 

 toe distinctly longer than fifth, etc. Not having seen any such 

 specimen, I am unable to express any opinion as to the validity of 

 this form, 



Sowerby collected an adult male (No. 52354) in southern Man- 

 churia on the Yalu River about 180 miles from its mouth. I am 

 unable to distinguish it from Japanese specimens. The inner meta- 

 tarsal tubercle, it is true, is rather large, and the digital disks 

 perhaps rather small, but each can be matched in my Japanese 

 series, though perhaps not in the same individual.

Nikolski, Fauna Rossij, Amph., 1918, p. 149 (Ussuii country to Trans- 

 baicalia). 



Two young specimens (Nos. 53367-8), largest 21 mm. long, were 

 collected by Sowerby at Imien-po, northern Kirin, Manchuria, and 

 are referred to under this heading in spite of the fact that I can 

 make out no markings. The digital disks, however, are scarcely 

 noticeable as such and the inner metatarsal tubercles are large. 



I am now inclined to think that the three specimens from Mon- 

 golia in the Museum of the Philadelphia Academy alluded to in the 

 Herpetology of Japan (p. 83), under the heading of Hyla arborea 

 im7nacuJata,^ really are identical with Sowerby's Manchurian speci- 

 mens.
