| Par les produits qu'elle fournit et le nombre d'hommes qu'elle occupe, la pêche de la morue tient, parmi les travaux auxquels s'adonnent les populations maritimes, une place prépondérante. Malgré cet intérêt et l'ancienneté de la découverte de Terre Neuve, les moeurs de la morue sont restées jusqu'à ces dernières années à peu près inconnues et les circonstances qui accompagnent sa migration demeurent encore obscures. La fabrication de l'huile de foie de morue est également mal établie et tout ce qui concerne la classification des huiles, leur différenciation et surtout l'identification des huiles natives n'a pas été jusqu'ici suffisamment étudié. |

| La connaissance des heures et des hauteurs des pleines et basses mers suffit, dans bien des cas, aux besoins de la navigation; mais il en est d'autres où la possibilité de connaître la hauteur de la mer à un instant quelconque rendrait de grands services, et le nombre de ces derniers augmente à mesure que la rapidité des communications devient plus nécessaire, que ce soit au point de vue militaire ou au point de vue commercial. |

| A skin of a male antelope, collected by Mr. A. Sharpe in Southern Angoniland has been described by Mr. Oldfield Thomas under a new specific title, Rhaphiceros Sharpei (P. Z. S. L. 1896, p. 796, plate XXXIX); the author had no cranial evidence of its age, as the skull of the individual was wanting. Mr. Oldfield Thomas remarked that it is »a Rhaphiceros with the white markings of the Grysboh (melanotis), but with the feet of the Steinbok (campestris)”, i. e. no accessory hoofs. Now the description and the figure of this animal, its small size, its short horns, its relatively short ears make the impression as if it is a young Grysbok; the absence however of the accessory hoofs is the difficulty: but if we suppose that those very small — especially in a young... |

| Among some fishes, forwarded by the late Dr. Bleeker to the Leyden Museum, I came across four specimens evidently belonging to the genus Arius, differing however from all known species of that genus. They therefore represent a new species, which I now describe under the name of Arius Bleekeri in honour of the great Ichthyologist, who collected them. The systematic position of this new species is between the two East Indian Arius macronotacanthus Blkr. and Arius coelatus Val. After having described it, I will compare my Arius Bleekeri with these two well-known forms. |

| Among fishes sent to the Leyden Museum by the late Dr. Bleeker, I found a Monacanthus which I cannot bring to one of the described species. It is a small specimen and it may be young, it is however interesting on account of its beautiful markings. When later on more or larger specimens will be found and it is proved that it is not the young state of a form already known, I propose to call it Monacanthus radiatus. The body is oval; the height, measured along the vertical line immediately before the second dorsal and the anal fin, is contained 2 times in the length without caudal and 2 1/2 times in the length with caudal; the breadth is contained 4 times in this height; the head is pointed and contained 4 times in the length with the caudal, in the posterior... |

| Seit Professor Schlegel zuerst mit Catalogisirung 1) der Vögelsammlung einen Anfang machte ist darin ein Stillstand eingetreten. Es war daher meine erste Aufgabe diese Arbeiten wieder aufzunehmen und zwar zunächst in Form eines Zettel-Cataloges, der, soweit es die übrigen laufenden Geschäfte zuliessen, befriedigende Fortschritte machte, indem derselbe bis jetzt 110 Genera in über 900 Arten und nahezu 4500 Exemplaren enthält. Ganz abgesehen davon, dass die eigenartigen Ansichten Schlegels über Systematik und Species den neueren Auffassungen nicht immer entsprechen, geben die von ihm publicirten Cataloge auch insofern keine richtige Uebersicht von dem heutigen Bestande der ornithologischen Sammlung, weil sich dieselbe seitdem bedeutend vermehrt hat. Ausser... |

| Mr. Karl Schädler, a German, formerly in service of the Dutch Indian Army, who collected for our Museum from December 1896 till middle of May 1898, went first to the northwest-coast of New Guinea and settled in the small place Sekru (Sekroe), situated a little east of Cape Meyer, on the south-coast of the peninsula which borders the big Bay of McCluer in the south. Mr. Schadler was staying here about 3 1/2 month (from 8 December 1896 till 22 March 1897) and sent home 247 specimens of birds (of which 179 are good prepared skins, the rest in alcohol), belonging to 76 species. Although they are all well known, an enumeration may be still of interest on account of the geographical distribution, being the first collection made on this part of the... |

| Piepers, M.C.. |
| At the Zoological Congress at Cambridge I imparted, especially for the exclusively English speaking and reading entomological public, some notions on this biological phenomenon, the existence of which I think to have discovered by studying the ontogenesis of caterpillars of Sphingidae, and also in the imagines of several families of Rhopalocera, more particularly in those of the Pieridae; the results of these studies have however been published in German. Now, before the Transactions of that Congress had been published, an article entitled » The Colours and Pigments of Butterflies” by Miss M. I. Newbegin appeared in the February number of »Natural Science”, in which, besides some other papers of these latter days on the same subject, she also discusses my... |

| When writing my introduction to Dr. Jentink’s treatise on the Mammals collected during my sojourn in Borneo (N. L. M. XIX (1897), pp. 1—26), I had no idea that the publication of the present paper, which at that time was nearly ready for the press, would have to undergo such a long delay. But the duties of my new position as Director of the Zoological Garden at Rotterdam absorbed so much of my time that I could not think much about finishing my manuscript. And even now I am, for want of time, unable to do what I originally had proposed myself to do, i. e. to give a critical review of the birds of Borneo, but must content myself with an enumeration of the species obtained by myself and my companions, especially by my assistant Mr. Max Moret, who, after my... |

| Amongst the numerous examples of Helota Mariae Rits. communicated to me by Mr. René Oberthür after the description of this species was published 1), and which came all from the same locality viz. Maria Basti in British Bhotan, I found a certain number of specimens which have the tibiae bicolorous, not entirely dark bronze as in Mariae. A careful examination convinced me that these specimens, though closely allied to Helota Mariae, belonged to an undescribed species for which I propose the specific name Margarethae. Besides by the coloration of the tibiae this new species is differentiated from Mariae by a somewhat larger size (especially observable in the male sex) and somewhat larger elytral spots, by the more strongly transverse prothorax, by the more... |

| The Stoat, Putorius erminea (Linne), has a differently colored summer- and winter-dress: its lower parts, margins of the ears and feet, however, constantly are of a whitish or yellowish white color and the terminal part of its tail remains black in all seasons. In winter in our temperate climate its coat sometimes is mottled with brown, but in severe winters it becomes entirely white: the more farther north the white is purer: in southern Europe and Asia it is brown the whole year all round. In our collection 1) is a rather complete series of individuals procured in different months, all from the environs of Leyden: this series shows very clearly the way by which the stoat turns white in winter and again brown in summer. |
