black. Lips with short papillae at the sides and long ones below. 

 Teeth feebly developed ; one long uninterrupted series above ; two be- 

 low, the upper narrowly interrupted, the lower short, less than half the 

 length of the one above. 



Dimensions. Total length, 33 mm., head and bodj' 11. Depth 

 of tail 6. 



Colour ( in life ). Reddish, brownish or olivaceous, thickly 

 speckled, the markings on the tail sometimes forming vertical bars ; a 

 darkish mark down the middle of the back and another along each side 

 of the body. Belly golden, throat blackish, with white spots. The 

 white longitudinal lines of the perfect frog maj' be present before the 

 creature leaves the water. The tadjjole closely resembles that of R. 

 eri/thrira. It ma_y be distinguished by its smaller size and by the 

 disposition of the teeth in the lower lip. In Ti". min'rodacti/la the upper 

 row is interrupted, and the lower one verj' short. In R. erifihra'a tiie 

 upper row is usually continuous and the lower one nearly as long as 

 the ujtper. 



I have obtained the tadpoles of R. macrodadi/la in June and 

 July shortly after the monsoon has broken, and they would probabl}- 

 be found as long as there is water in the fiekls. They are very active 

 creatures and usually seek to avoid capture bj' concealing themselves 

 in the mud. 



Eana lateralis Bouleng. 



This frog has been fuund in several localities in both Central 

 and Eastern jSiam, and I have obtained the ta(l()oles at Nong i'lingand 

 'J'a Kiia (C. Siamj in July and August. They were found in dec)) 

 pools of water.
