Specimens were collected at Belimbing (Legeh), Biserat, and 

 Singapore in the botanical gardens.

I caught a young specimen at Kwala Aring, and another nearly 

 full-grown at the foot of Gunong Inas. 



Rana signata Giinther.

I caught a single young specimen of this Frog at the foot of 

 Gunong Inas, and saw but could not catch a much larger individual 

 in the same locality. It has not hitherto been recorded from the 

 Peninsula, but is known in Borneo.

These handsome Frogs are extremely common along the banks 

 of the rapid jungle torrents running about the foot of Gunong 

 Inas. They sit on the great boulders strewn along the courses of 

 the streams, and when one approaches them spring boldly into the 

 water, no matter how 7 fiercely it may be pouring down. Soon after 

 being disturbed they will again take up their station on the rock 

 which they had quitted, and in such a position their colouring 

 renders them well-nigh invisible. 



The tadpole is provided with a well-developed ventral sucker 

 extending from the lower lip to beyond the middle of the abdomen. 

 The beak is of two pieces, an upper and lower minutely serrated. 

 The arrangement of the labial teeth is

It is thus apparently closely allied to the tadpoles of Rana 

 jerboa Blgr., li. latopalmata Blgr., R. cavitymjpanum Blgr., and 

 Staurois hainanensis Blgr. 



Coloration is much as in the adult, greenish white, mottled 

 with dark green on the back ; ventral surfaces white. There are a 

 few minute black denticles scattered on the head. Total length of 

 the single specimen caught 65 mm., tail 45 mm.
