| SYNOPSIS The type slide of the species Fedrizzia helleri briefly described by Oudemans 1929 from Paramaribo, Dutch Guiana, but never figured, has been re-examined. The species is now shown to belong not to the genus Fedrizzia Canest. (fam. Fedrizziidae) but to the genus Klinckowstroemiella Turk 1951 (fam. Klinckowstroemiidae). The species Fedrizzia helleri was briefly described by Oudemans 1929 as follows: "Fedrizzia helleri nov. sp. Er is geen scherp begrensd sikkelvormig scutum verticale; wel is dit gedeelte naar den voorrand membraneus; die voorrand is niet zuiver rond, maar iets golvend; er zijn 4 stralende vertikaalhaartjes op geplaatst, die op gelijke afstanden van elkander staan. Verder is de rug haarloos. ♀ genitaalopening trapezoidaal, vóór bijna... |

| In June 1954, during an ecological study of the mangroves near the Research Station of the São Paulo University Oceanographic Institute at Cananeia, about 200 km south of Santos, southern Brazil, Dr. S. Gerlach of the Zoological Institute and Museum of the University of Kiel, Germany, collected some Crustacea representing three species of Decapoda Macrura; two of these belong to the family Alpheidae and one to the Callianassidae. I am most grateful to Dr. Gerlach for the privilege to study this small but interesting collection, which now is the property of the Kiel Museum; duplicate specimens are inserted in the collection of the Rijksmuseum van Natuurlijke Historie at Leiden. Family ALPHEIDAE The two species of Alpheidae were collected near Cananeia,... |

| In meiner vorigen Mitteilung (Bemerkungen über Pedipalpi, Zoologische Mededeelingen 's Rijks Museum van Natuurlijke Historie te Leiden Deel XIV, Afl. 1—2, 1931, p. 79—88) habe ich schon darauf hingewiesen, dass man bei der Bearbeitung der Thelyphonidae auf eigentümliche Schwierigkeiten stösst. Diese Schwierigkeiten werden hauptsächlich dadurch verursacht, dass das spärliche Material dieser Gruppe über sämmtliche Museen der Welt zerstreut ist. Herrn Dr. E. Titschack vom „Zoologischen Staatsinstitut und Zoologischen Museum" in Hamburg, der mir das Hamburgische Material worunter die Typen der folgenden Arten: Thelyphonus Latr., em. Poc. borneensis Krpln.; Th. celebensis Krpln.; Th. hanseni Krpln.; Th. manilanus var. halmaheirae Krpln.; und den von KRAEPELIN... |

| A new species of freshwater palaemonid prawn, Macrobrachium oxyphilus spec, nov., is described from highly acidic blackwaters in a peat swamp forest in Selangor, Peninsular Malaysia. The species differs from its nearest congener, M. trompii (de Man, 1898), in having proportionately smaller eyes, shorter scaphocerites, a lesser number of ventral rostral teeth, a more inflated carapace, and less pubescent and more spiniferous chelipeds. |

| In einem umfangreichen Material europäischer Pseudoscorpione, das mir Herr Dr. L. van der Hammen vom Rijksmuseum van Natuurlijke Historie in Leiden zur Bearbeitung zuleitete, befand sich folgende neue Microcreagris-Art: Microcreagris gallica n. sp. (Fig. 1) Relativ kleine Tiere mit blass gelblichbraunen Hartteilen. Carapax etwas länger als breit, glatt, mit 6 Hinterrandborsten, sein Vorderrand flach gewölbt, dahinter mit flachem, nasenförmigem Medianrücken, der jedoch nicht vorspringt. Beiderseits zwei kleine, flache, ganz dicht beisammen stehende, sich berührende Augen mit kleinen Pigmentbechern. Beborstung der Abdominaltergite: 6-8-10-10 etc., Endtergit mit langen Tastborsten. Pleuralmembran sehr grob und gleichmässig granuliert („gesteinelt"). Kaudale... |

| Among the hermit crabs collected by Dr. L. D. Brongersma, Dr. L. B. Holthuis, and Dr. M. Boeseman on the reef of Biak Island near New Guinea 1) there are five specimens bearing the Peltogastrid parasites dealt with in the present paper. They belong to previously described species but present some peculiarities supplementing certain data mentioned in other papers. Dipterosaccus indicus Van Kampen & Boschma Dipterosaccus indicus Van Kampen & Boschma, 1925, p. 3; Boschma, 1931b, p. 6; Van Baal, 1937, p. 25; Shiino, 1943, p. p. Material examined: No. 1331, length 8, breadth 3, height 4 mm (fig. 1g-i). No. 1326A, length 7 (in reality somewhat longer, the body showing a pronounced curvature), breadth 3, height 3 1/2 mm (fig. 1d-f). No. 1326B, length 7,... |

| In a previous paper (Boschma, 1935) I made some remarks concerning the parasites of Pachygrapsus crassipes Randall from Japan, viz., Sacculina confragosa and the specimens mentioned then under the name Sacculina rotundata. The latter parasite, indeed, shows some resemblance to S. rotundata, but a closer examination of its characters shows that it is specifically distinct from this species. It appears to be a new species which is described in the present paper as Sacculina yatsui. Moreover the results of a more or less detailed investigation on Sacculina rotundata are given here to show the differences between the two species. Sacculina yatsui nov. spec. Sacculina rotundata: Boschma 1935. Material examined: Sagami Bay, 1901, Dr. Haberer. Zool. Museum... |

| INTRODUCTION Dans sa monographie pourtant très complète de Sacculina carcini Thompson, publiée en 1884, Delage ne traite pas de l'étude embryologique de cette espèce. Il ne se désintéressait pas pour autant de ce sujet sur lequel il exprimait son intention de revenir „plus tard, dans un moment opportun". Les seules recherches d'embryologie descriptive antérieures à l'„Évolution de la Sacculine" sont dues à Van Beneden (1869-1870). Van Beneden a bien vu la division totale de l'oeuf en deux, puis en quatre blastomères ègaux, mais l'impossibilité où il s'est trouvé de suivre la division des noyaux l'a conduit à considérer qu'il y avait, après ce stade, séparation de „quatre cellules embryonnaires sous forme de petits globes protoplasmiques pourvus chacun d'un... |

| Van de ruim 100 soorten vlokreeften (Amphipoda) die tot nu toe in het Nederlandse faunagebied zijn aangetroffen (Vader, manuscript), behoort meer dan de helft tot slechts vier families, te weten de Gammaridae (22 soorten), de Corophiidae (11), de Haustoriidae (10) en de Talitridae (9); de rest is verdeeld over niet minder dan 20 andere families. Van deze grote vier hebben de Haustoriidae altijd mijn bijzondere aandacht gehad, en in dit artikel wil ik proberen een overzicht te geven van de verspreiding en biologie van een van de meest spectaculaire vertegenwoordigers van deze familie, Haustorius arenarius (Slabber). Voor wat de verspreiding betreft is het overzicht gebaseerd op de amphipodencollecties van de Nederlandse musea en marien-biologische... |

| Acanthochondria Oakley is a genus of parasitic copepods, the members of which usually cling to the gills or gill arches of fishes, or to the mucous membrane of their buccal cavity, or to the inner surface of their operculum. Two new species of this genus recently obtained in Japan are described here in some detail. Acanthochondria yui sp. nov. (figs. 1, 2) Occurrence. — On the operculum, the gill arches and the roof of the buccal cavity of Acanthogobius flavimanus (Temminck & Schlegel), taken at the estuary of the river Aikawa, Tsu, Japan, by Mr. K. Mori. 19 females on one host, 22 on another; each associated with a male. One of the females from the former lot is selected the holotype. Female. — The colour is whitish, the egg tubes are white.

| A new alpheid shrimp, Thuylamea camelus gen. nov. & spec. nov., from Dong Hoa, a coastal community of Can Gio district, and northwest of Vung Tau (Cap St. Jacques), Vietnam, is described and illustrated. The new genus appears not to be closely related to any of the previously described genera. It has the postero-dorsal margin of the carapace armed with two high and short crests which are slightly outward inclined and directed backward, and between these crests with a low but distinct conical spine, and an elevated conical boss in the anterior median area slightly behind the anterior margin of the first abdominal somite. |
