20 PROCEEDINGS OF THE NATIONAL MUSEUM Vol. G(i 



No. 1056, Bedriaga has at least one of the eight specimens of No. 

 1501, from the River Braga-gorgi, as R. asiatica^ while Nikolski 

 has three out of the same batch under R. asiatica and three under 

 R. tetnporaria. Moreover, Bedriaga refers Middendorff's specimens 

 from Udskoi Ostrog to R. asiatica^ while Nikolsld keeps them in 

 R. tcmforaria where, I have no doubt, they really belong. 



Mehely's suggestion ^^ that Middendorff's Aldan and Udskoi speci- 

 mens, as well as Bedriaga's R. asiatica., really are Rana arvaJis I 

 simply mention to show how divergent the opinions are as to these 

 frogs. 



Recently ^^ Boulenger has made R. 'ja.fonica include specimens. 

 from practically the whole of China and Japan, from Canton and 

 Yunnanfu to Yezo and the mouth of the Amur. This disposition of 

 the east Asiatic grass frogs does not seem to meet the requirements 

 of the case, and in the absence of a discussion and disposal of R. 

 martensi and of R. asiatica I am unable to accept his view, at least 

 for the present. 



In this uncertainty I have preferred to follow Nikolski in treating^ 

 this form binominally. 



This is the form which Sowerby found all along his route with 

 Colonel Clark in Shansi, northern Shensi, and Kansu in 1908 and 

 1909. A fine series, including specimens from Taiyuanfu, Shansi 

 (Nos. 39326-30), Yulinfu, Shensi (Nos. 39331-2), 50 miles east of 

 Yenanfu, Shensi (Nos. 39360-6), 25 miles "northeast of Chingning- 

 chow, Kansu (Nos. 39354-9), and 20 miles east of Kingyangfu,. 

 Kansu, at Ho-shin (No. 39367) testify to his zeal and skill as a 

 collector and observer. There are also in the collections received 

 from him later on specimen obtained by A. L. Hall in northeastern 

 Chili, at Hei Sui, close to the Mongolian border (Nos. 53374-8) 

 and by himself in Manchuria, at I-mien-po, North Kirin (No- 

 53370).
