THOMSON: KHIPIDISTIAN SNOUT 323 a series of dorsal bi-aiu-hes which pass out of ihc ciKlocraiiiuin (Fig. 1, ) and obviously contained branches of the nerve supplying the sense organs of the supraorbital lateral line canal. The canal for the ophthalmicus superficialis VII curves forwards through the roof of the nasal capsule and emerges from the endocranium at about the level of the anterior wall and thence continues in the space between the endocranium and the dermal bones. The anterior wall of th(> nasal (•ai)su]e is pierced by a series of fine canals (Figs. 3, 4, ) which communicate with the palatal recess and the medial surface of the premaxilla. A fine canal (Fig. 3, ) passes through the posterolateral corner of the nasal capsule from the medial surface of the lachrymal bone without entering the nasal cavity. The medial wall of the capsule is pierced by two nerve canals in addition to the canal for the olfactory tract. The more pos- terior of the two canals (Fig. 3, ) leaves the nasal cavity. Figure 4.
