22,5 Taylor: Herpetological Fauna, III 523 



Specimens of Rana magna usually are discovered perched on 

 banks of small mountain streams in which they take refuge on 

 the approach of anyone. The frog is sought for food all over 

 the Islands, and very large specimens are rare. 



Specimens from northern Kalinga appear to have better- 

 developed spiny tubercles over the body than the southern 

 specimens, particularly in the latter half of the back. Speci- 

 mens from Ifugao, obtained by Prof. H. Otley Beyer, appear to 

 represent a distinct species. However, the specimens are all 

 young, and the fixing fluid has hardened them. I await more 

 material before disposing of these forms.
