with margin of black. Teeth occupying whole wadth of inner 

 surface of lip ; formula 2/3. In smaller specimens (from nurse 

 frogs and pools, PI. I, Fig. 3), the upper row is interrupted in 

 the middle, the first lower series is very feeble and the upper 

 lip is strongly developed. With an increase in size the lower 

 lip becomes relatively less prominent and the first lower row of 

 teeth larger. (PI. I, Fig. i). In the largest specimens from 

 the pools (20 mm.) the second upper row of teeth is not always 

 interrupted. 



In alcohol the coloration is as follows : blackish above, snout 

 semi-translucent with dark blotches on sides and above nostrils, 

 sides lighter with dark spots, ventral surface uniform grey, 

 tail crests immaculate, yellowish grey, muscular portion of tail 

 colored with an occasional sprinkling of black dots. In life 

 small tadpoles were uniform black, the heads of the older 

 specimens conspicuously golden.
