    • n occipital In zoology and anatomy, the occipital bone; the bone of the hindhead; a compound bone, consisting of a basioccipital, a supra-occipital, and a pair of exoccipital bones, circumscribing the foramen magnum, and together constituting the first or occipital segment of the skull. These several elements commonly coalesce; but the basioccipital may be represented only by cartilage, as in a batrachian; or some of the elements may unite with otic elements and not with other occipital elements; or several of the elements may unite with one another and also with sphenoid, parietal, and temporal elements. The occipital bears two condyles for articulation with the atlas in all mammals; one in all Sauropsida (birds and reptiles); one (or, if two, as in a batrachian, with no ossified basioccipital) in Ichthyopsida. See cuts under Balænidæ, Catarrhina, craniofacial, cranium, Cyclodus, Esox, Felidæ, and skull.
    • n occipital In herpetology, one of a pair of plates or scutes upon the occiput of many serpents. See cut under Coluber.
