Tadpoles. — Length of body one and a half times its breadth, more 

 than half the length of the tail. Nostrils inconspicuous, situated 

 nearer the eye than the end of the snout. Eyes on the sides of the 

 head, nearer to the end of the snout than to the spiracnlum. Distance 

 between the eyes more than four times that between the nostrils, more 

 than half the width of the mouth. Spiracnlum on the median line 

 directed backwards and downwards, situated nearer the anus than the 

 end of the snout. Anal opening on the middle line. 



Tail. — Length more than twice the depth. Obstusely pointed. 

 Upper crest about as deep as the lower. Depth of muscular portion less 

 than half the total depth. 



Mouth. — No hard beak, teeth nor papillse.

26. Callula triangularis. — I have only obtained this at Cbimanji 

 at an elevation of 3,000 feet under stones and logs. I know nothing of 

 its habits. 



27. Cacopus systoma. — This burrowing frog is fairly common in 

 the low country, but not much in evidence, as it is entirely nocturnal. 

 The breeding season is in June and July. The eggs are globular and 

 are placed in large irregular masses, which may be found floating in the 

 paddy fields. As development progresses, the eggs sink.

 end of the snout. Eyes on the sides of the head nearer the end of the 

 snout than the spiraculum. Distance between the eyes five times that 

 between the nostrils, two and a half times the width of the mouth. Spira- 

 culum on the median line directed downwards and backwards, situated 

 close to and in front of the anus, which also opens in the middle line. 



Tail. — Length three and a half times its depth, acutely pointed. 

 Upper crest about as deep as the lower. Depth of the muscular
