An excellent description and figures of Arabian specimens of this 

 tadpole were given by the late Dr. J. Anderson in the paper cited above. 

 Through the kindness of Dr. Boulenger we have been able to compare 

 some of these specimens with Indian examples. They are larger and 

 stouter than any we have seen from this country, but there is consider- 

 able difference in this respect between specimens from different Indian 

 localities. 



The tadpole mav be distinguished from all other Oriental larvae with 

 which we are acquainted, except that of Rana hexadactyla , by the arma-

ture of its mouth. Its beak, though stouter than that of most species, 

 is less stout and less prominent than that of the tadpole of Rana corru- 

 yata} in which there is no horny pad on the mouth-disk below the beak. 

 The condition of the inner row of teeth on the upper lip is variable. 

 Sometimes it extends right across the disk, but it is usually interrupted 

 more or less broadly in the middle line. Occasionally it is almost com- 

 pletely absent. 



Full-grown Indian speeirnens are usually about 65 to 75 mm. long ; 

 the tail is less than twice as long as the head and body ; its dorsal mem- 

 brane rises more or less abruptly a little in front of the posterior extrem- 

 ity of the body, and the top of the head is flat.
