The distinction between the genera of the Talitridae is mainly based — at least where the Dutch species are concerned — upon the shape and size of propodite and dactylus of the gnathopods (cf. TESCH: Talorchestia brito etc. in Zoologische Mededeelingen, 's Rijks Museum van Nat. Hist., Leiden, Dl. II, 1916). Intermediate between the genera Talitrus and Orchestia is the remarkable genus Talorchestia, which STEBBING christened with that compound name because the females should be referred to Talitrus, but the males to Orchestia, if we ignored that they belong together. For the second gnathopod of the males carries the huge hand, which distinguishes Orchestia ♂ ♂ from Talitrus ♂ ♂. The females, however, differ from those of Orchestia in that their 1st... |

Die Poriferen-Ausbeute der Curaçao-Expedition Herrn Dr. C. J. VAN DER HORSTS verdient nach zweifacher Richtung besonderes Interesse. Einmal gewährt sie in die Schwammfauna des südlichen Teiles des Karaibischen Meeres Einblick, von der bisher erst sehr wenig bekannt ist. Seit der „Argo”- Expedition des Jahres 1876 ist die Spongien-Fauna dieses Gebietes nicht mehr untersucht worden. Ueber die Spongien von Curaçao lagen bisher in der Literatur überhaupt noch keine Angaben vor. Sodann liefern die Sammelergebnisse und Standorts-Aufzeichnungen Dr. VAN DER HORSTS Angaben über die ökologischen Ansprüche einer Reihe westindischer Schwammarten. Es ist kaum nötig zu bemerken, dass hier noch fast völlig Neuland vorliegt. Die Schwamm-Ausbeute, von der im folgenden das... |

For the reason that no records for this group of animals have been made anywhere near that region, the Bryozoa collected by Dr. C. J. VAN DER HORST are of great interest. The collection is quite limited in the number of species, as might have been expected on account of the inconspicuous nature of most of them. Only the specialist in the group, accustomed to collect these minute animals and familiar with their habits of growth, occurrence and appearance, need ever expect to take a very complete series of them. Most of the species in the collection appear to be there incidentally, attached to shells, corals, etc., and were later found on close inspection. A considerable number of the species are represented by only one or two specimens and the examination... |

Bei der Durchsicht mehrerer holländischen Andrena-Sammlungen fand ich eine Art, welche, soviel ich weiss, bisher noch nicht beschrieben worden ist. Sie gehört zu der schwierigen Gruppe der A. ovatula K. (afzeliella K.), und ist der A. wilkella K. (xanthura K.) am nächsten verwandt. Nach Herrn R. C. L. Perkins, dem ich einige Stücke dieser neuen Art zusand, fehlt sie in England; auf dem Festlande ist sie sicher weiter verbreitet, aber da die Unterscheidung von den Verwandten, besonders bei abgeflogenen Stücken, sehr schwierig ist, hat man sie wohl in der Regel mit A. wilkella K. oder ovatula K. verwechselt. Die folgende Beschreibung habe ich aufgestellt nach 5 ♀♀ und 12 ♂♂: Andrena gelriae n. sp. ♀. Schwarz. Kopf ungefähr wie bei wilkella gebildet, nur der... |

As I have already pointed out in the Narrative of the Voyage (this journal Nr. 23) there is a marked difference between Caracasbay and Spanish Water, the former having clear blue ocean water, the latter being rather muddy. Spanish bay is quite the same as Caracasbay except that it is less sheltered against the tradewinds. Spanish Port is a narrow channel connecting Spanish Water with the bay and shows the transition in the different nature of the water. This difference has a great influence on the fauna as is shown especially by the coral population. For the rest the coralfauna of the West Indies is extensively described by POURTALÈS (III. Cat. Mus. Comp. Zool. No. IV. 1871), VERRILL (Trans. Conn. Ac. Vol. 11. 1901), and VAUGHAN (The stony corals of the... |

A species with the habit of Aristida divaricata H. et B., but welldistinguished by the wanting column and the curious tuberculate lemmas. Closely allied to Aristida gentilis HENR., which differs however in the other position of the glumes and in the smooth lemma. The species resembles in some characters the Aristida Parishii HITCHC., the latter has however a totally different shape of the panicle and the lemma is not tuberculate-hispid, but scabrous only on the upper half. Among duplicates from the U. S. Nat. Herbarium, kindly received from Mrs. A. CHASE, I found a second plant belonging to the species, a plant also collected in Arizona, north slope of Santa Rita Mountains, leg. D. GRIFFITHS no. 7269. |

INTRODUCTION. A complete description of the summer plumage of Tringa canutus never seems to have been given. For this reason alone it might be of some value to describe it in more detail than has been done before. The chief object of the present paper, however, is not the description of the summer dress, but the discussion of a problem connected with it, which is of much more general interest. As the same problem presents itself in the summer plumage of one of the Knot's nearest relatives, the plumage of this bird, Tringa crassirostris, will be dealt with in the latter part of the present paper. I have to thank my friend Dr. H. Boschma for his valuable assistance in the preparation of this paper. III. THE PLUMAGE OF TRINGA CANUTUS L. 1. MATERIAL. The... |

In het brakke water van de Zeeuwsche eilanden komen Bryozoën voor, die tot het geslacht Membranipora behooren en die zich van de andere soorten van dit geslacht onderscheiden door den vorm van de kolonie. De dieren liggen hier niet, zooals bij de meeste Membranipora's, tegen het substraat aan, maar vormen afstaande korsten, die tot groote, samengestelde klompen kunnen uitgroeien en die zich vasthechten aan palen en bruggen. Deze Bryozoën zijn door een aantal onderzoekers, die ze tot zeer verschillende soorten brachten, in Zeeland en het omgevende gebied gevonden. In „Flora en Fauna der Zuiderzee" vermeldt Mej. van Benthem Jutting (1922) dezen vorm als Membranipora membranacea (L.) var. erecta Loppens, naar aanleiding van de determinate van overeenkomstige... |
