During the dry season I have not seen this frog at Bangkok, but from the middle of M a y to August they are very plentiful in suitable ponds and are to be bought in the market, as R. tigrina is eaten by the Siamese ; I have heard 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 line 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 found 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 ; during the latter half of July females were to be 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 M a y :- Above olive-brown or pale olive-green, with very dark greenish-brown or black spots on the head, sides, and limbs ; the back either spotless or with large dark spots; on the legs the spots may become broad dark transverse bars : no vertebral line. Below, body and limbs immaculate silvery white, between which and the green upper surface there is an irregular space of lemon-yellow with greenish-brown spots. The lips, chin, and underneath of head are lemon-yellow, with more or less distinct dark spots ; sometimes there is a median dark line from the symphysial angle to the breast. The vocal sacs of the male are dark grey, shaded with pink. Iris dark brown, with narrow golden ring round the black pupil. Half-grown specimens are often prettier coloured than the adults, being rich green above and pure white below, with many black markings. Size.
