 than broad ; snout rounded, as long as the diameter of the orbit ; 

 canthus rostralis rather indistinct ; interorbital space as broad as 

 the upper eyelid ; tympanum somewbat more than half the diameter 

 of the eye. Fingers and toes moderate, the tips very indistinctly 

 dilated ; first finger shorter than second ; toes with a slight rudiment

Mr. Cope considers this Frog specifically distinct from O. ornatus, 

 and identifies it with Hyla ocularis of Daudin. The latter opinion I 

 cannot share, as nothing in the French author's description and 

 figure indicates the least analogy with this form. The toes are 

 represented as balf webbed in H. ocularis, and the digital expansions 

 of O. copii are so slight that they would certainly have escaped 

 Daudin's observation. Moreover the colour is quite different.

 borders projecting a little behind the posterior margins of the latter. 

 Head wide, flat ; snout obtusely rounded, a little longer than the 

 diameter of the eye ; canthus rostralis well marked but contracted ; 

 tympanum half the diameter of the eye. The hind limb being 

 carried forwards along the body, the tibio-tarsal articulation reaches 

 the front of the orbit. Skin smooth above, granulate beneath.
