Head small; snout short, rounded, without canthus rostralis ; 

 eyes and nostrils turned upwards : former small, their diameter 

 equalling the distance between their front border and the nostril ; 

 upper eyelid reduced to a mere fold of the skin : a very short ten- 

 tacle below the eye. Fingers very slender, acutely pointed, sub- 

 equal in size ; toes strong, depressed, pointed, very broadly webbed, 

 the three inner furnished with black corneous sheaths imbedding
