 with dark spots, and a pale vertebral streak ; and the larger females as greyish-olive, 

 with dark spots. This is the common ' Bull f log ' of the Europeans in India, and has 

 a powerful voice ; though when the animal is concealed, it is often difficult to make 

 out where the voice emanates from, by the sound.

 in the general form of its body ; but approaches R. Kuldii in its fang-like apophyses, 

 almost hidden tympanum and metatarsal tubercle. 



Inhabits Tenasserim. See Blvth, J.A.S.B. 18.5.5, p. 719, and Anderson, P.Z.S.L.

{Liimnoclyt.es is preferable to Ilyhrana as less misleading, as it is an essentially 

 water frog, and its dilated extremities do not (as has been supposed) indicate an 

 arboreal or semiarboreal life.)
