| Our knowledge of the Hymenoptera of the Island of Waigeu hitherto has been based on the material collected by Dr. A. R. Wallace and described by Mr. Frederick Smith in the Journal of the Linnean Society of London, 1863, pp. 6—48. Omitting the bees (5 species) and the ants (27 species) Smith describes and enumerates 27 species of the Families dealt with in this paper. An examination of this list shows a great difference between the species collected by Mrs. de Beaufort and Dr. Wallace, as will be seen by the Catalogue given here for the purpose of making my paper more complete and useful as regards Waigeu. |

| A very beautiful and by no means common species of Saturnidae of the tropical region is Actias maenas. In the year 1847 Doubleday has bestowed this name upon a female and a year later a male has been named Actias leto by the same author (Annals of Nat. Hist. vol. 19, pag. 95; Transactions Entom. Soc. London, vol. 5, pag. 1i). Doubleday’s female type originates from Silhet, the male from India Orientalis (very undefinite!). It was unknown to Doubleday and also to Walker, that maenas and leto belong to the same species, the latter giving in the List of spec. of the British Mus. (pag. 1263) a diagnosis of a male Tropaea maenas. After Rothschild’s publication it is unquestionable that the species ought to be named „maenas” and that „leto” is a mere synonym. In... |

| Helota attenuata belongs, together with Dureli, Moutoni and Helleri, to the group of Helota rotundata (see my „Synopsis” in Notes Leyd. Mus. Vol. XIII, p. 227). It is easily recognizable among these species by the coarse punctuation on the pronotum and by the reddish testaceous colour of the elytral epipleurae. When I described the species, the female sex only was known to me (Notes Leyd. Mus. Vol. XVI, p. 112), but later on Mr. René Oberthür received also the male sex from the environs of Kurseong (R. F. Bretaudeau) and from Maria Basti and Padong in British Bhotan (R. F. Durel). |

| By his decease the Leyden Museum of Natural History has lost a Director, who during nearly thirty years has given all his energy to this Institution, has tried to extend and to complete its collections and to bring its internal arrangement more in agreement with modern views. In the first years of his employment at the Museum (Conservator, 1875—84) he had the good fortune to study under the guidance of Hermann Schlegel and to be introduced by him in the System of the Mammals; for to this class he applied nearly all his scientific labour and he has published a great number of papers on them. Especially by his publications on the Bats and the Rodentia he became known as a learned and accurate scientific investigator. However a good deal of his time in the... |

| There are in the Leyden Museum two specimens of an Amphidromus, that I was not able to identify with any species represented in our collection. In my opinion they had characters of both A. porcellanus Mouss. and A. sumatranus Marts., and also of A. adamsi Rve, which latter species has notoriously numerous forms. To be quite sure I asked the advice of Mr. Hugh C. Fulton, who had the kindness of comparing the Leyden Museum specimens with specimens in his own collection. Mr. Fulton wrote to me that the larger specimen agrees with specimens of his own, which lie decided were a variety of A. semifrenatus Marts., while he possessed also specimens as carinate as the smaller one, which may possibly belong also to this species. Thinking it might be of some interest... |

| The Herbarium of PERSOON in the Rijks Herbarium at Leiden is of the greatest interest in connection with many mycological questions of classification and nomenclature. Many well known mycologists have made a careful study of the types, preserved in the collection and have expressed their opinion in different notes added to the specimens. A comparison of these notes is of the highest interest. The object of the present paper is to bring together the notes that have been added to the different specimens of Polystictus Polyporus, and Fomes. In many cases I added further notes of my own, which I made during the last two years. Many of these notes are based on correspondence I have had with M. BRESADOLA, to whom I sent a great many specimens for comparison. For... |

| Infolge eines glücklichen Zufalls besitzt der Zoologische Garten der hiesigen K. Zoologischen Gesellschaft „Natura Artis Magistra” seit einiger Zeit zwei Exemplare von Zaglossus; einen Zaglossus Bruynii nigroaculeata Rotsch. und einen Zaglossus Bruynii Peters et Doria. Diese seltenen Tiere leben hier seit zwei Jahren in bestem Wohlbefinden und leiden dem Anschein nach nicht infolge ihrer Gefangenschaft. Dank dem liebenswürdigen Entgegenkommen des Herrn Dr. C. Kerbert, Direktors der K. Zoologischen Gesellschaft, war es mir möglich an diesen Tieren einige einfache Beobachtungen und Versuche zu machen, die nicht an und für sich, wohl aber wegen der ausserordentlichen Seltenheit des Studienobjektes einiges Interesse darbieten werden. |

| In two recently arrived consignments of Natural History objects from Simalur and neighbouring islets, brought together by Mr. Edw. Jacobson who since has left this locality, were 3 female Lucanidae belonging to different species and found on the island Simalur. They are: 1'. Odontolabis gracilis Kaup, in v. Harold’s Coleopterologische Hefte, IV (1868), p. 77. — Leuthner, Trans. Zool. Soc. London, XI (1885), p. 438. One female (n°. 3981) from Sinabang, May 1913. |

| At Station 282, off the North East point of Timor, at a depth of 27—54 M., a single Polynoid-worm was kept, that is characterized not only by the singular shape of its elytra, but also by the abnormal manner of their attachment. For the elytra have not the usual appearance of flat, scale-like organs, that are attached at their under side, but they are represented by small oval buds, not quite so high as broad and fixed at their median side to a long elytrophore; there are 26 pairs of them, as in other Lepidasthenia-species situated on segment 2, 4, 5, 7, 9—23, 26, 29—65. They are quite smooth and without any appendages. About the internal structure of these organs ¹) I have observed, that like in other elytra there is an epidermis-layer of polygonal cells,... |

| Lately the Leyden Museum received from Prof. K. Martin some specimens of Siphonaria sipho Sow., collected by himself at Batoe Kapal on the eastcoast of Hoeamoeal, a peninsula of the island of Ceram, one of the Molucca’s. Now it is not to be wondered at, that this species, widely distributed in the Molucca’s, was also found in the quoted locality; but an observation about its mode of attaching, made by Prof. Martin, who communicated it to me, and kindly allowed me to publish it, seems to be very remarkable. On a piece of „Glimmerschiefer” (n° 389 of Prof. Martin’s collection) he observed some small specimens of Siphonaria sipho, attached with their apices to the stone, so as to form little cups. Prof. Martin himself loosened the shells and took the soft... |

| The Leyden Museum of Natural History received a small number of Pieridae from the islands Pulu Babi and Simalur, collected by Mr. Edw. Jacobson. Mentioning eight species only, I call attention to the importance of this small collection, because two species prooved to be new and three other ones were represented by most interesting varieties. Especially the islet Pulu Babi seems to possess a remarkable fauna, deviating from that of the neighbouring islands. Pulu Babi is a coral-islet, totally overgrown with a dense, by people little visited forest. The following is an enumeration of the species received, with description of the novelties. |

| Die unten aufgezählten, von Herrn de Beaufort während seiner Reise 1909—10 gesammelten Amphibien bringen eine wünschenswerte Bereicherung unsrer Kenntnis der noch sehr unvollständig bekannten Batrachierfauna einiger Inseln aus dem östlichen Teile des Indischen Archipels, besonders von Waigeu und Ceram. Von der erstgenannten Insel ist bis jetzt nur eine einzige Art beschrieben worden und zwar Rana papua Less., die zuerst während der Reise der „Coquille” im Anfang des 19. Jahrhunderts dort gesammelt wurde 1). Von Ceram sind bisher nur drei Hyla-Arten bekannt (H. dolichopsis Cope ²); H. vagabunda Ptrs. & Dor., von d’Albertis gesammelt ³), und H. kampeni Barbour 4). |

| Worms belonging to the genus Psammolyce, that are characterized by having their elytra and the median part of their back covered with papillae, adapted for the retention of small particles of the bottom upon which they are living, hitherto were not observed in the Malay Archipelago. Yet the Siboga-expedition had the good luck to collect a number of them (though often in fragments), that certainly represent three species. However it is no easy task to recognize the characters, offering a trustworthy criterion for the distinction of the species. With regard to the elytra f. i. Willey says: „they are not safe objects for comparison, since they vary from segment to segment” ¹); however Potts rightly stated, that certain features of the elytra as a whole are... |

| In 1908 Dr. F. A. JENTINK, Director of the Natural History Museum at Leyden (Holland) and Dr. TH. W. VAN LIDTH DE JEUDE graciously extended the courtesy of allowing me to study for a few weeks in the Herpetological Department of the Leyden Museum. The type specimens of Elaps collaris which were described by SCHLEGEL in 1837 were examined. This species was correctly placed by its author in the genus Elaps. It belongs to the group that is characterized by Mr. BOULENGER as having the “symphysial in contact with the anterior chin-shields”. It is allied to E. narduccii JAN, which it resembles in having the sixth supralabial in contact with the parietal and in the colour pattern of the body. It is specifically distinct in the following details: The parietal... |
