BATRACHIANS OF THE MALAY PENINSULA. 397 



Kelantan. I have also met with it at 4,500 ft. elevation on the 

 Larut Hills, Perak, and on the Semangko Pass between Selangor and 

 Pahang, In the latter locality I found them inhabiting little tunnels 

 six inches or a foot deep, apparently made by themselves, in banks of 

 sandy soil. 



If laid on its back and tickled on the breast with the finger this toad 

 will invariably fold its arms across its chest and lie as if dead, remain- 

 ing thus for a considerable time after it has been left to itself. 1 have 

 recollections of a picnic at the Batu Caves when a number of these 

 toads thus entranced were laid in a row, affording considerable amuse- 

 ment ! 



Flower gives the length of his largest specimen as Gf inches, and

There is a specimen in the British Museum from Singapore from

 cessfully! It must be quite common in Selangor, at least near Kuala 

 Lumpur. I can always obtain any number of tadpoles at any time of 

 the year, but so far I have only succeeded in capturing a single adult, 

 which measured l|-f , in- from snout to vent. I noted the colour 

 in life as ; 



Greyish brown above, marked with large dark-brown patch.es> 

 arranged in three irregular rows down the back, and each narrowly

 nostril, and back through the eye over the tympanum. Sides greyish, 

 marked with black spots and blotches. Hind limbs barred and blotched 

 with black ; inside of thighs and anal region light greenish blue. 

 Lower surface grovish white, finelv mottled throughout with brown. 

 Eyes very prominent, entirely black. The larval period of existence
