 of the eye ; canthus rostralis rather indistinct ; lorcal region oblique, 

 slightly concave ; eye very prominent ; upper eyelid narrow ; inter-

 or not quite half the diameter of tbe eye. Three outer fingers half

 like in males ; toes three-fourths webbed ; disks as large as, or nearly 

 as large as, the tympanum ; subartieular tubercles little developed. 

 The hind limb being carried forwards along the body, the tibio- 

 tarsal articulation reaches the tip of the snout. Upper surfaces, 

 belly, and lower surface of thighs granulate. Colourless ; males with 

 a few scattered white dots on the head and back ; females with a 

 cross-streak between the eyes, a streak from the nostril, and a few
