larger. The teeth also are smaller, especially on the last row on the 

 lower lip, and the beak even less powerful and with the margin of the 

 upper part nearly straight. Our specimens are not in sufficiently good 

 condition to provide material for a detailed statement as to proportions 

 but we believe that our figure gives an adequate idea of the outline. 



Geographical distribution of the species. — Plains of Southern India 

 and Ceylon.

The tadpoles can be recognised by the obcardate body whose great- 

 est width is about the pectoral region. The snout slopes, is blunt and 

 rounded. The eyes and nostrils are dorso-lateral in position ; the latter 

 nearly five-sixths as long as the eye, looking upwards and outwards. 

 The internasal space equals the distance between the nares and eyes 

 and the width of the mouth. The mouth is fairly large, the lower 

 lip being better developed. The papillae are confined to the corner 

 of the mouth and slightly extend to the margin of the lips. Dental 

 formula 1 : 1 + 1/3. The three series on the lower disc are subequal. 

 The skin is smooth. A preorbital or lachrymal gland may be fre- 

 quently present, as also series of sensory pits on the dorsum and about 

 the flanks of the body. A frontal gland is faintly marked. The 

 spiraculum is a conspicuous tube, visible from below, directed back- 

 wards, nearer to vent. The length of the tail slightly more than 

 3| times the total depth. The dorsal lobe is more strongly arched, 

 the tip rounded. The colour of the dorsal surface is deep black, 

 the throat bronzed. The abdomen and fin membranes are white, 

 immaculate.

A series of tadpoles and toads from Rawalpindi in the nottli of the 

 Punjab belong to this species. 



The tadpoles are very small, not exceeding 20 mm. in length when 

 full orown. The head and bodv are moderatelv flat, rathei' narrow! v
