Family BUFONIDAE 

 Key to the Bufonid Larvae found in the Plains of India. 



I. Colour almost uniform black or brown ; only slightly 



paler on the fin-membranes and ventral surface. 



A. Nostril half as 1 irge as eye .... Bufo fergusoni. 



B. Nostril less than half as large as eye. . . Bufo mdanostictus. 



C. Nostril more than three-fourths as l.irge as eye . Bufo microtympa- 



num. 



II. Colour more or less mottled or speckled ; ventral 



surface distinctly paler than dorsal surface, at any 

 rate anteriorly. 



1. Dorsal profile of tail with a low and gradual con- 



vexity : habit rather slender ; dorsal surface 



of head and body with minute white specks . Bufo stomaticus. 



2. Dorsal tail fin elevated immediately behind the 



body ; habit stouter . colouration dark . . Bufo viridis. 



The only genus known from the plains of India is the universally 

 distributed genus Bufo. The tadpoles of most species of this genus 

 resemble one another very closely and can only be distinguished by 

 slight differences in proportions, in colouration and in the relative 

 lengths of the rows of teeth on the disk. In all those found in the plains
