Genus CHARIIVA, Gray. 



Gen. Char. Resembles Wenona in general shape and appear- 

 ance, and bears with it many affinities in structure. There are two 

 lorals instead of one ; three anteorbitals instead of one ; three super- 

 ciliaries instead of one ; and the subcaudal scutellae much narrower, 

 and more elongated transversely. The comparison of specimens will 

 no doubt show other generic differences inappreciable by the de- 

 scriptions.
