Helminth parasites from two species of hornbills (Bucerotidae) are described. These helminths are: a young trematode of the genus Eumegacetes, which is not specifically identified; a new species of cestode - Raillietina (Fuhrmanetta) lophoceri; two new species of proventriculus nematodes- Tropisurus prozeskyi and Microtetrameres bucerotidi and a gizzard nematode - Hadjelia inermis (Gedoelst). All these helminths are described and figured.
