RATRACHIAXS FROM WEST AFRICA 



16H 



Fernando Po: Musola, 500-700 m. 



An advanced tadpole with fully developed hind limbs and re- 

 duced tail, from Musola, has preserved the 

 larval mouth, which is here figured. The 

 lower mandible is shaped like a Y, with 

 the branches feebly diverging; three rows 

 of labial teeth above and as many beneath, 

 the outer upper marginal, the outer lower 

 with a papillose border; a median chink 

 in the upper lip.
