The two or three African species belong to {Atelodus}, and have two horns, but lack the dermal folds, and the incisor and canine teeth. The two Malay, or East Indian, two-horned species belong to {Ceratohinus}, in which incisor and canine teeth are present. See {Borele}, and {Keitloa}. [1913 Webster]
