rare, but are more numerous in tlie iiortlieni half. In Siam proper 

 they are exceeding!)' common. I have no records of anj' specimens

0. lima is strictly aquatic in its habits, and I have never seen it 

 away from water. It haunts the open rice-fields and smalls ponds. 

 Its crj- is a liarsli, chattering note, and it is the only frog in Bangkok 

 that maj' be heard calling at any time of the year. It feeds chiefly 

 upon ants and spiders. 



('. laevis martens!, although never far from water, is seldom to 

 be found ia it, preferring the road-side ditches, where it seeks con- 

 cealment in the long grass or dense foliage b}' the water-side. From 

 this habit, as well as from ir.s small siz>, it is seldom seen and is a 

 dilHoult frog to catch. Once its note can be recognized, however, an 

 unobtrusive and not unmusical " chink, chink " often repeated, it is 

 amazing what numbers of these creatures reveal themselves. Eveiy 

 compound, every road, in fact, practically every patch of green 

 throughout the whole citj^, seems to harbour some of tliem. Through- 

 out the rainy season the}' may be heard at any hour of the day or 

 night, but in the dry weather they are silent. They remain active, 

 however, throughout tlie year.
