892 MR. STANLEY S. TLOWEIl OX THE [XoV. 14, 



heard in tlie middle of tbe day, betraying its pref=ence. During 

 the dry season I have not seen this frog at Bangkok, but from the 

 middle of May to August they are very plentiful in suitable ponds 

 and are to be bought in the market, as E. tir/rina is eaten by the 

 Siamese ; I have beard Malays speak of the Siamese by the name 

 " Frog-eaters," in consequence of this. Small Siamese boys may 

 be seen fishing for these frogs with a short rod and a very fine 

 line with a small hook with a white bait ; this is danced and dangled 

 over the surface of the water near the edge of a pond as if it were 

 a fly hovering about ; when a frog springs at this the angler has 

 to " strike '" very quickly, to catch the hook in the frog's mouth to 

 draw it out of the water. I also fouud this species at Ayuthia in 

 June. 



Breeding-season. A pair were observed in copula in Bangkok in 

 May, the male was considerably smaller than the female ; dui-ing 

 the latter half of July females were to he found with the ovaries 

 distended with spawn, ready for expulsion. But well-grown 

 tadpoles were found as early as the first week in June, in Ayuthia, 

 and on the 28th July in Bangkok, when young frogs were leaving 

 the water. Thus the breeding-season must extend over some 

 months. 



Colour (in life). Description drawn up from adult specimens 

 of both sexes caught in Bangkok in May : — 



Above olive-brown or pale olive-green, with very dark greenish- 

 brown or black spots on the head, sides, and limbs ; the back
