The rough-nosed horned lizard or Sri Lanka horned agama (Ceratophora aspera) is an Agamid lizard from Sri Lanka in lowland dipterocarp forests and secondary forests in the wet zone. It is distinguished from all the other Ceratophora species by the presence of a complex rostral appendage, comprising more scales than rostral scale alone. The lateral body scales are small and more or less regular shape.
