Schlegersfig. 5 on Plate III'' of the Saurii and Batrachii of Fauna 

 Japonica is usually referred to Polypedates scMegelii, but I think 

 erroneously. The webbing between the digits and the shape of the 

 snout, as well as the coloration, indicate Hyla arhorea. Moreover, 

 an examination of the specimen in I^eiden Museum shows that this 

 view is correct. 



In his catalogue of the tailless batrachians in the British Museum 

 (18S2) Boulenger recognized four varieties of Hyla arborea, of which 

 H. arborea savignyi was credited to various islands in the Mediter- 

 ranean, parts of western Asia, and to the island of Hainan, South 

 China (a single half-grown specimen), while //. arborea jayonica 

 was represented as being confined to Japan. In 1887 (July) he re- 

 corded '^ a specimen of the latter from Port Hamilton, a small island 

 at the south end of Korea, opposite Kiusiu, found together with 

 another specimen which he described as Hyla stepheni. Shortly 

 before (January, 1887) he had referred a specimen from Gensan, 

 Korea, to H. arborea var. savignyi,'^ a reference, by the way, which 

 appears to have escaped Doctor von Bedriaga.* 'While the latter 

 author, as well as Boettger-^ still recognize //. arborea japonica, 

 Boulenger in his latest important work^ after the study of a large 

 series of specimens (34 from the Mediterranean and western Asia 

 as far as the Persian Gulf and 18 from Japan, Korea, and China)
