The development of the upper eyelid into a horn-like dermal 

 appendage has been considered one of the chief characters of the 

 genus Ceratojihri/s. But in C. ornata it is so little marked that it 

 evidently should be used merely as a specific character. The 

 species hitherto separated as Odontophrynus (Reinh. & Liitk.) or 

 Fi/.ricephahis (Giinth. nee Tschudi) are therefore united with Cera- 

 tophrys, the whole forming a very natural genus.
