| In preparing a small Handbook of the Netherlands Opisthobranchiate Mollusca (Fauna van Nederland, Afl. VIII, Sijthoff, Leiden, 1936), in cooperation with Miss Tera van Benthem Jutting, the present author studied, as his part of the work, the Nudibranchia. As some results of his studies might be of more general interest, they are given here. The southern North-Sea is rather poor in animal life and it is always interesting to note, what species can live under the rather bad ecological conditions it affords. The number of species diminishes further as one enters the Waddenzee or (before 1932) the Zuiderzee. Though as a rule the sandy Dutch coasts are not suitable for Nudibranchs, there are found some on the stone-covered dikes and quays, on the wooden... |

| Mme PRUVOT-FOL, 1933, p. 400, established the subgenus Tullia for Aplysia juliana QUOY et GAIMARD, and 1934, p. 41 added other species of Aplysia with a distinct sucking disk at the end of the foot. Living animals have been figured and their variation has been described by BABA 1937a, p. 211, and 1949, p. 24 and 125 as Tethys and Aplysia sibogae. In a recent paper, PILSBRY, 1951, beautifully figured and described the living animals as Aplysia (subgen. nov. Metaplysia) badistes nov. spec. He points to the fact (verified in our preserved animals) that the anterior part of the foot-sole also tends to form a sucking disk. However, it is not separated by a (more or less distinct) groove from the rest of the foot (see PILSBRY’S fig. 4) as is the posterior disk.... |

| Das Material dieser Untersuchung lieferten die 1920 von Dr. C. J. VAN DER HORST auf Curaçao gesammelten Opisthobranchiaten. Hier wird nur die einzige vom ihm gefundene Aeolidiade: Phidiana brevicauda nov. spec. besprochen. Dr. TH. MORTENSEN stellte mir eine Sammlung Opisthobranchien aus dem zoologischen Museum in Kopenhagen zur Verfügung, welche auch dem westindischen Meere entstammten. Darunter befand sich auch nur eine Aeolidiade: Berghia coerulescens Laur. |

| Bei meiner Untersuchung dieser von Dr. VAN DER HORST auf Curaçao gesammelten Mollusken, standen mir auch wieder Tiere aus dem zoologischen Museum in Kopenhagen und aus dem Senckenbergischen Museum zur Verfügung, wofür ich Dr. TH. MORTENSEN und Dr. F. HAAS meinen wohlgemeinten Dank bringe. Die Aeolidiadae wurden in einer in der 24. Lieferung dieser Zeitschrift erschienenen Arbeit behandelt, die übrigen Tiere hoffe ich in einer späteren Arbeit zu besprechen. |
