Since the term pituitary, derived from the root pituita, or phlegm, was adopted by the ancients because the structure was believed to supply the mucous secretion to the nasal membrane, we suggest abandoning it and accepting the alternate term hypophysis.

However, this communication does not concern the hypophysis itself but the parahypophyseal lesions, which are commonly called tumors of Rathke's pouch and craniopharyngeal tumors or craniopharyngiomas. But these last two terms, as Tilney says,1 are unquestionably
