1. In addition to the already well-known neurosecretory magnocellular nuclei of hypothalamus, a new gomoriphil small nerve cell group was observed in tuber cinereum. These cells were found to exist close medianly, immediately under the ependymal layer of the lateral wall of the third ventricle, in front of the mammillary body, most of these cells lying in areas of nucleus infundibularis of H. Spatz and his coworkers.<BR>2. These nerve cells were found to be highly gomoriphil in the processes rather than in the cell body. The cells were found to be bipolar or pseudounipolar and both neurite and dendrite proved to be gomoriphil. Neurite was found to run into infundibulum from pars retroinfundibularis tuberis. The origins of these fibers are quite different from that of tractus paraventriculohypophyseus, these fibers form an independent tractus, i. e., tractus tuberohypophyseus. But both tracts may not be differentiated from each other after entering the infundibulum.<BR>3. Nerve cells given here were observed most markedly in dog subjected to partial hypophysectomy.<BR>4. The ending of this tract is not known, but at least, the existence of a new gomoriphil tract arising from tuber cinereum and entering into the hypophysis has been demonstrated.<BR>5. The fate of the gomoriphil substance observed in dendrite and collateral branches is not known.
