In the horse the tubes terminate in avery different manner. When the head is removed at the occipito-atlantal articulation, and the pharynx, with the associated structures,carefully dissected from the muscles on the ventral aspect of the cer-vical region of the spine, it will be found, as a rule, difficult to avoid Wall of pouch Fig. 326.—Tracheal oi^euing and pouch of an emu.

They reach to the base of the skull, extenddownwards to the larynx, and send processes to occujiy the intervalsbetween the long styloid processes and the mandible. These sacs arethe guttural pouches; they abut upon, but have no communicationwith, each other, and occupy the whole of the naso-pharynx. Eachpouch is lined with delicate mucous membrane containing glands andfurnished with ciliated epithelium.

The pouches them-selves appear as large saccular dilatations of the terminal ends ofthe tubes, and for this reason th
