second," against "first not longer than second." In the coloration 

 the most notable discrepancy is in the markings on the limbs, which 

 in R. adenopleura arc said to be marked "with dark cross bars," but 

 in R. taipehensis ''with longitudinal dark stripes." Boulenger com- 

 pares his species with /.'. pleuraden, Van Denburgh his with R. 

 i rythrsea. 



POLYPEDATES MOLTRECHTI (Boulenger). 



L908. Rhacophorus moltrechti Boulenger, Ann. Mag. .Nat. Hist. (8), Mil. 2, 

 Aug. 1908, p. i'L'1 (type-locality, Lake Candidje, Nauto district, central 

 Formosa; types in Brit. Mus.; Dr. A. Moltrecht, collector); vol. I, Dec. 

 1909, ]>. 495 (Kosempo, Formosa). 



Not as yet reported from outside Formosa. 



POLYPEDATES ROBUSTUS (Boulenger). 



1909. Rhacophorus robustus Boulenger, Ann. Mag. Nat. Ili.-t. (8), vol. I. I >< c 

 1909, p. 194 (type-localities, Kankau, Alikang, and Kosempo, Formosa; 

 H. Sauter, collector'). 



According to Boulenger this form is closely allied to P. buergeri of 

 Japan (Herpet. Japan, 1907, p. 150). 



POLYPEDATES EIFFINGERI (Boettger). 



(Herpet. Japan, 1907, p. L53.) 



1895. Rana eiffingeri Boettger, Zool. Anz., vol. 18, July 8, 1895, p. 267. 

 Rhacophorus eiffingeri Boulenger, Ann. Mag. Nat. Hist. (8), vol. 1. Dec. 

 1009, p. 495 (Kanshirei, Formosa). 



The recording of this form in Formosa by Boulenger is very inter- 

 esting, since, like P. robustus, it is also related to P. buergeri, of which 

 species it has been regarded as the Riu Kin representative. It is 

 consequently the more to be regretted that the exact locality of the 

 type of P. eiffingeri is not known. The question also arises whether 

 any form corresponding to P. robustus may not occur in the Kin Kin 

 Archipelago. As another possibility it is suggested that Hallowell 

 may have been correct in recording P. burgeri from the "Loo Choo 

 Islands," and from "Ousima." 



POLYPEDATES JAPONICUS (Hallowell). 



(Herpet . Japan, 1907, p. 155. i 



1860. Txalus japonicus Eallowell, Proc. Acad. Nat. Sci. Phila., 1860, p. 501. 

 Rhacophorus japonicus Boulenger, Ann. Mag. Nat. Hist. (8), vol.4, 

 Dec. 1909, p. 195 i Kankau, Formosa). 



This is another Riukhian species, now for the first time recorded 

 from Formosa. As I have already shown in the Herpetology of Japan, 

 it does not occur in Japan proper, notwithstanding the specific name 

 given it by Hallowell.
