Approximating Phyllobates in the slight development of the vomerine teeth, 

 and further characterized by the shortness of its feet. The former are in two 

 very short transverse patches behind and within the line of the middle of the 

 choana?, and separated by an interspace as wide as the length of each. The 

 tongue is obpyriform, rounded and extensively free behind. The ostia pharyngea 

 are minute. The membranum tympani is indistinct, with a diameter of less than 

 half that of the eye slit. The head is an oval in outline, with narrowly truncate 

 and depressed muzzle. The canthus is obtuse, but not concave. Nares subter- 

 minal ; diameter of orbit about equal length of head in front of it. Cranium 

 above slightly convex in both directions. 



The toes are short, and the digital dilations are large on all the feet. On the 

 anterior the first toe is shorter than the second. On the posterior the fifth is 

 longer than the third, and reaches the base of the penultimate phalange of the 

 third. The muzzle marks the wrist and the middle of the tibia of the extended 

 limbs.
