I caught a. single example of a Frog, apparently belouging to this 

 species, in thick jangle at Kwala Aring. It is a female and much 

 larger than the type (70 mm. from snout to vent). The back is 

 grey, with very curious glandular folds running obliquely backward 

 from left to right, making an angle of about 45° with the long axis 

 of the body. The tympanum is as large as the eye. A black line 

 from the tip of the snout passes back through the eye and broadens 

 above the shoulder, disappearing abruptly immediately behind the 

 tympanum. The flanks are grey with a few black spots. This 

 species has hitherto been found only in Burmah.

Malay name : " Katak pisang," Banana Frog. 



This is perhaps the commonest of the Malay Frogs and is 

 abundant everywhere. The measurements of the largest specimen 

 obtained, a female, are : — 



Snout to vent 75 mm. 



Thigh to knee 38 ,, 



Knee to ankle 37 „ 



Ankle to end of 4th toe 47 ,, 



At Kwala Aring we found this species breeding in the month 

 of September and the end of August. The eggs were laid in 

 a frothy mass on the leaves of trees overhanging small pools of 

 water. After a short time (I believe less than 48 hours) they slid 

 off the leaves and fell into the water, where the frothy envelope 

 is dissolved away, setting free the tadpoles. (Gf. S. Ikeda on

A single specimen from Kwala Aring was caught in long grass 

 close to a small pond on the edge of the jungle.
