Large samples of frogs and lizards from eight lowland forested environments distributed in Borneo, Malaya, and north- eastern Thailand are used to compare abundances. Frogs and lizards were divided into riparian and non-riparian subsam- ples, and each of those into arboreal and terrestrial categories. Non-riparian lizards were further divided into diurnal and nocturnal groups. The two forests in Thailand lie in an area having a pronounced dry season and prolonged intervals of extremely high temperatures in contrast to the Indo-Malayan environments which lack those features. The differential ef- fects of drought and high temperatures on portions of the environment during the day and the varying susceptibilities of the taxonomic and ecological groups probably are responsible for differences observed in relative abundance. Frogs of all categories were more numerous in Borneo and Malaya than in Thailand. Diurnal arboreal lizards were much more abun- dant in Borneo and Malaya, whereas terrestrial ones, nocturnal and diurnal, were more abundant in both Thai forests. Nocturnal arboreal lizards showed a mixed picture.
