    Description / Table of Contents: Zusammenfassung Im sessilen Bulbus olfactorius von Teleosteern werden große Nervenzell-Somata als bulbäre Riesenzellen beschrieben. Sie treten bei Arten mit einem gestielten Bulbus nicht auf. Ihre Anordnung geht parallel mit dem bulbären Verlauf des Nervus terminalis. Holmgrens „Kaudale Zellgruppe“ bzw. das „Kerngebiet des Nervus terminalis“ (Scharrer) ist eine häufig anzutreffende Gruppierung dieser Zellen am caudalen Bulbusende. Es wird die Möglichkeit erörtert, ob die bulbären Riesenzellen nicht den Ganglienzellen des Nervus terminalis verwandte Strukturen darstellen.
    Notes: Summary Large nerve cell somata are described as bulbar giant cells in the sessile olfactory bulb of teleostean fishes. They are not found in species with a stalked olfactory bulb. They are arranged along the bulbar course of the nervus terminalis. In the “Kaudale Zellgruppe” of Holmgren and the “Kerngebiet des Nervus terminals” of Scharrer a greater part of these giant cells lie at the caudal end of the bulb. It is discussed if these cells are related to the ganglion cells of the nervus terminalis.

    Notes: Summary The giant cells in the olfactory bulb of labyrinth fish, most likely belonging to the nervus terminalis, show ultrastructural features of active synthesis of secretory material. Dense core vesicles (70–100 nm in diameter), found in the perikaryon as well as in the axon, are the possible storage sites of the secretory substance. Its chemical nature is unknown. In some of these vesicles acid phosphatase is demonstrable. Large membrane-bound bodies (up to 2000 nm in diameter), either containing an electron dense matrix or debris of cytoplasmic organelles, are also acid phosphatase-positive, suggesting their lysosomal nature. Some other ultrastructural characteristics of these cells are also described.
