Two specimens are from Prome, fiYQ from Ava, six from Ponsee, two from 

 Momien, and one from Hotlia. In the two adults from Prome, a number of the 

 tubercles between the two prominent metatarsal tubercles have united, evidently by 

 pressure, to form a flat black horny -like disc. The gradual formation of this disc 

 can be traced in the other specimens. In young individuals from Ponsee and 

 Momien, small tubercles occur far forwards on the top of the snout. The vertebral 

 series of large tubercles can hardly be distinguished from others in that region. The 

 head of the large adult from Hotha is more triangular than in the Prome specimens. 

 In very young ones from Ava, the warts and all the tubercles on the head defining the 

 position of the future ridges are bright pink. They have also a faint interocular band. 



In travelling down the Irawady to Mandalay my attention was attracted one 

 evening, after my boat had been moored for the night, by a loud croaking, only a few 

 yards olf, close by the margin of the river. The sound was so loud that I resolved 

 to ascertain what species produced it, and accordingly I had a torch lit and pro- 

 ceeded in the direction of the sound, and soon came upon a pair of toads, seated 

 upon a floating bamboo, with up-lifted heads and dilated throats. They ceased 

 immediately the light approached, but began again after a few seconds, when 

 I secured both, and found that they were examples of this species. I was quite 

 unprepared to find that the very loud sound was produced by this species, as Cantor 

 has described its call as a plaintive chirping sound. 



This toad is prevalent in Upper Burma and in the high country to the east as 

 far as Momien, where it is interesting to observe that it is associated with the newt 

 Tylototriton,

Blyth's example of this species was from Pegu ; but the species has since been 

 obtained in Sikkim, at an elevation of 3,000 feet, and also in the Khasia hills.
