Conclusions 354 Bibliography Reference letters 359 Introduction In 1901 Minot published an account of the morphology of the pineal region in which it was shown that the characteristic struc- tures included therein had their beginnings in constant well-defined divisions of the fore-brain roof. These subdivisions constitute a succession of arches and intervening projections into the ven- tricle, and in Acanthias are recognizable in embryos of 11.5 mm. JOtTBNAL OF MORPHOL.OQT, VOL. 21, NO. 3
