These two bones are united in the middle line : each consists of a tooth-supporting portion, which completes the maxillary arch, and an ascending pro- cess, to the apex of which the nasal cartilage is articulated by a movable joint (an). As muscles are attached to this process, it becomes a lever, by which movements are ef- skill! of liana cscnli'iifa, seen from below, tvice natural size. 13.

Are two transverse bony bars, situated under the anterior portion of the sphenethnioid bone on either side : each ex- tends outwards from the apex of the parasphenoid to the maxillary bone, where this gives off its ascending process to the nasal bone. * For OS nasale, Cuvier {I. c, g), cornet (concha), Dugès, see cartilaginous nasal capsule, p. 27.
