| Having received from Mr. A. L. van Hasselt of Padang Sidempoean, among some other interesting beetles from Sipirok (North West Sumatra), a couple of a beautiful Calandrid of the group Rhynchophoridae, viz. Macrocheirus spectabilis Dohrn, I carefully examined the materials of this group in the Leyden Museum, and this examination convinced me of the necessity of dividing Schönherr’s genus Cyrtotrachelus in two genera. The following table will clearly show the distinctive characteristics of the genera of the first division of Lacordaire’s group Rhynchophorides (Genera des Coléoptères. Tom. VII. p. 271): a. Elytra distinctly narrowing backward, conjointly emarginate at the end. |

| A few years ago a new and interesting mammal, which is exceedingly rare, even in its native haunts, was brought to the then Resident of Palembang, Mr. A. Pruys van der Hoeven. This gentleman who is not only an eager sportsman, but also well-versed in natural history, recognised it to be new to science and to be more closely allied to certain representatives of the Edentata, than to any other order of mammals. — The type-specimen was held in captivity for several weeks, was fed on ants and afterwards on cooked rice and was sent alive to Europe in order to be examined, described and ultimately preserved in the Royal Museum at Leyden. It unfortunately died on board the vessel, on its way to Holland, and by an unaccountable blunder on the part of one of those... |

| Length 7 mm. — Elongate elliptical, much more broadly rounded in front than behind, convex (above and beneath) in the transverse as well as in the longitudinal direction so that the insect is highest just before the middle of its length. Subshining, pitchy brown, darker above than beneath and than the legs and antennae, the tarsi and the short antennal joints pale rusty red; the whole insect covered with a tomentose pubescence and moreover, especially on the upper surface, with long erect hairs; the colour of the entire pubescence is greyish yellow with the exception of an ill-defined transverse spot on the highest portion of the back where the hairs are black, which spot is very conspicuous when the insect is seen sideways. Head entirely hidden under the... |

Antennae very long and slender, the last 5 or 7 joints generally more or less incurvate, the scape of the colour of the head, the other joints becoming gradually paler, being only infuscate at both the extremities.

| A few weeks ago we received the sad news from Robertsport of the decease of our Liberian collector A. T. Demery. This is a great loss for the sake of zoological investigation in Liberia and the neighbouring districts of Sierra Leone, and especially for our Museum which, by this death, looses its last direct connection with that part of Western Africa. As the readers of our »Notes” will remember, the collections received from Mr. Demery since about a year were very interesting, and amongst many objects contained several novelties. His last collection, made on the Sulymah River, is expected in here every day, and as soon as we will have received it, an ample list will be prepared of the birds collected by him on the mentioned river. |

| In the Zoological Garden of Dresden, since the year 1887, there has been a living specimen of a Cercopithecus, brought hither from Central West-Africa by Dr. Ludwig Wolf. This specimen so obviously represents an undescribed species of monkey, that I need not hesitate any longer in describing it shortly, though this can be done but imperfectly during its life-time. The following remarks, therefore, must be looked upon as preliminary only, to be completed after the animal’s death. This new species belongs to the Mona-group, which was divided by Prof. Schlegel (Cat. Mus. Pays-Bas, Singes, 1876, p. 80) into those with white over the root of the tail and those-without it. |

| Shell fusiform, white; whorls 8, slightly concave at the upper part, rather inflated and rounded beneath; nucleus smooth and semitransparent, each of the next whorls with about 10 costae, which become obsolete on the 6th and are entirely wanting on the ultimate and penultimate whorl. The entire surface of the shell, with exception of the nucleus, is covered with close set lines of growth and spiral lirae, of which latter there are 13 on the penultimate whorl, besides a few much finer intermediate ones, which alternate rather regularly with the coarser lirae and are more clearly seen on the ultimate whorl; the lirae are slightly granulate. Last whorl regularly contracted to the base and produced into a moderately long canal, which is slightly curved.... |

| Last year our Museum received a very large earthworm, collected in Brazil by Mr. H. du Dréneuf. I believe the specimen must be identified with Anteus gigas, though it does not agree in all its characters with the description given by Perrier of this species ¹). This description was based upon two specimens, one from Cayenne, the other from an unknown locality. Although our worm is not in a very good state of preservation, so that some interesting points of its organisation remained unknown to me, my examination has enabled me to add something to our rather scanty knowledge of this species, and to come to a certain conclusion about the question of its supposed identity with Microchaeta rappi. Vaillant ²) pointed out that, according to Perrier’s description,... |

| Freie Foraminiferen sind in der vorliegenden Sammlung nicht vertreten, wohl aber eine grosse Reihe von Gesteinen, welche die Gehäuse dieser Thiergruppe enthalten und zum Theil von ihnen aufgebaut wurden. Die Untersuchung musste demnach an der Hand von Dünnschliffen vorgenommen werden und geschah in der Weise, dass von allen Handstücken, in denen nach vorläufiger Prüfung mit der Loupe Ueberreste von Foraminiferen überhaupt erwartet werden konnten, Praeparate gefertigt wurden. Das Resultat der Untersuchung ist, auch dort wo es negativer Art war, in die anhängende Liste zur Charakterisirung der betreffenden Gesteine aufgenommen worden. Dass sich beliebig durchschnittene Gehäuse von Foraminiferen, sowie sie Dünnschliffe bieten, in den seltensten Fällen zur... |

| Das fusus-ähnliche Gehäuse trägt ein hohes Gewinde, dessen embryonaler Theil aus einem einzigen, glatten Umgange besteht und ohne scharfe Grenze in die Mittelwindungen übergeht. Die Zahl der letzteren beträgt vier; sie besitzen einen scharf ausgeprägten Spiralwinkel, welcher den hinteren, leise concaven Abschnitt der Umgänge von dem vorderen, convexen, scheidet. Die Querwülste, deren Zahl bis zu elf beträgt, fallen nur wenig in die Augen; im Spiralwinkel tragen sie je einen länglichen Knoten, und nach vorne schliesst sich hieran noch eine zweite Längsreihe von Knoten an. Zwischen beiden entwickelt sich am jüngeren Gehäusetheile bisweilen eine Spirale, und zwei weitere, deutliche Spiralen begleiten die vordere Naht. An der Schlusswindung sind die Querwülste... |

| Bei der Terminologie für die Gastropoden liess ich mich, wie bereits früher, durch die vom lebenden Thiere eingenommene Stellung leiten. Die Spitze wird somit im Folgenden als „hinterer,” die Schlusswindung als „vorderer” Abschnitt der Schale bezeichnet, gleich dem „oberen” und „unteren” Abschnitte bei der Terminologie anderer Autoren, welche von der aufrechten Stellung des Gehäuses hergeleitet ist. Dem entsprechend ist für den vorderen Theil des letzten Umganges der Ausdruck „Stirnabschnitt” und, falls letzterer in eine Spitze ausgezogen ist, derjenige einer „Nase” angewandt. Unter „Basis” verstehe ich stets die Fläche, mit welcher das Thier beim Kriechen aufliegt, im Gegensatze zu der nach oben gekehrten „Kückenfläche” des Gehäuses, für welche bei... |

| Im Nachfolgenden habe ich mich bemüht, eine Uebersicht meiner Abhandlung » Die Myoxidae oder Schläfer. Ein Beitrag zur Osteologie und Systematik der Nagethiere, mit 5 Tafeln. Verlag von Trap, Leiden, 1890” zu geben. Dass dieses Excerpt, denn mehr ist es nicht, in der Zeitschrift des Leidener Museums seinen Platz findet, ist mir deshalb sehr lieb, weil die ganze Abhandlung im hiesigen Museum ausgearbeitet ist. Im System sind die Schläfer bei den Nagethieren untergebracht, wo sie das eine Mal zu den Eichhörnchen, das andere Mal zu den Mäusen gerechnet werden. Waterhouse (Observations on the Rodentia. Charlesw. Mag. Nat. Hist. New Ser. Vol. III. p.p. 91, 184. 1839) spricht zum ersten Male von einer Familie der Myoxidae. Ihm folgt später Wagner (Gruppirung der... |
