Variation.—The variations in this species are chiefly in color- 
ation, that given being most nearly typical. Sometimes the 
color of the back is bronze with yellowish spots or reticulations; 
sometimes the blue-green skin on sides and belly has a slight 
wash of yellow; certain specimens are dark greenish brown 
with cream yellow spots on sides and back; a small specimen 
in the Bureau of Science collection preserved in alcohol (No. 
1669) has all the legs barred with brown and cream, a darker 
line from tip of snout through eye above tympanum, and the 
back brown, with cream reticulations. 
Remarks.—This species is common in Leyte, Mindanao, Pa- 
lawan, and Busuanga. It is also known to occur in Culion, 
Dinagat, and Basilan, in the Philippines, and is reported from 
Celebes.*° The species is always found in the immediate vicinity 
of water, usually perched on rocks, in midstream. The frogs 
are extremely agile, and can make phenomenal jumps. They 
are captured with no little difficulty. 
The types were collected in the Philippines, probably by Hugh 
Cuming; the exact type locality appears to be no longer known. 
The types, three in number, are in the British Museum. 
Genus POLYPEDATES Tschudi 
Polypedates TscHupti, Class. Batr. (1838) 34; Dumférim and BIBRON,

* Boulenger, Proc. Zool. Soc. London (1897) 193-237, does not include 
the species in the Celebes fauna. He states that Meyer’s record, Abh. 
Mus. Dresden 2 (1887) 16, of Rana natatrix Gthr. from Gorontalo 1s 
probably wrong. 
* Stejneger (loc. cit.) has shown the necessity of the use of Polypedates 
instead of Rhacophorus for this genus of frogs.
