The neurosecretory system of Emberiza rustica latifascia was studied by applying the paraldehyde fuchsin and luxolfastblue-cresylviolet staining methods. In this species, neurosecsetory cells were widely scattered not only in the hypothalamus but also in the ventral part of the thalamus. The main neurosecretory cell groups were the supraoptic and paraventricular nuclei as in mammals ; the supraoptic nucleus was further divisible into the pars medialis and the pars lateralis and the paraventricular nucleus into the pars periventricularis and the pars diffusa. In addition to these nuclei, a dense group of neurosecretory cells was found in the lateral forebrain bundle, distributed from the lateral hypothalamus to the ventral thalamus (Figs. 1-3). These cells formed a mass of neurosecretory cells were located further laterally to the paraventricular group and were different in shape from those of the paraventricular group. The neurosecretory cell group were mostly multipolar or stellate in shape, while the paraventricular group spindle-shaped or ellipsoidal. This neurosecretory cell group was designated as "entopeduncular neurosecretory cell group", since the neurosecretory cells of this group occurred in the entopeduncular nuclear group (described by Huber and Crosby, 1929). A similar neurosecretory cell group has already been described in Zosterops and given the same name by the senior author (Arai, 1962, 1963). Uemura and Kobayashi (1963) have also reported this group in Zosterops.
