A Malay brought me a single male specimen of this interesting- 

 Toad, which he had caught squatting on the ground amongst dead 

 leaves in dense forest on Ctunong Inas. I believe this is the first 

 specimen taken in the Peninsula. Its coloration and proportions 

 are closely similar to those of the type specimen from Borneo. 



Distance from snout to vent 30 mm.

Mr. Annandale collected a large number of the tadpoles of this 

 species at the foot of Bukit Besar in Jalor. They are very 

 curiously coloured, being a pale yellow and spotted with numer- 

 ous fine black dots. (See Hanitsch, Rep. Baffles Mus. & Libr. 

 Singapore, 1897, p. 8.)

This Frog is fairly common in the Botanical Ciardens at Peuang, 

 where I obtained two specimens, one young and one adult. A 

 specimen in the University Museum at Cambridge from Java 

 (labelled Megalophrys montana) is very much more richly coloured, 

 especially on the under surface, than are either of my specimens 

 or others that I have seen from the Peninsula. 



Megalophrys Montana Kuhl.

Mr. Annandale caught an adult female on Bukit Besar in Jalor 

 at a height of about 2000 ft. ; and I found one adult and three 

 young on Gunong Inas at from 1000 to 1500 ft. above sea-level. 

 It is a very sluggish animal, as is also the first species of the genus. 



The following are the principal measurements of an adult : — 



Snout to vent 65 mm. 



Thigh to knee 25 „ 



Knee to ankle 20 „ 



Ankle to 4th toe 42 „ 



Total length of hind leg 93 „ 



The tadpoles of M. montana were found in the same locality
