| After having examined Gray’s type of Acanthomys leucopus) and compared that animal with my description of Mus leucopus ²), Alston comes to the conclusion 3), “that I have been misled by Gray’s very insufficient description”. I am the first to agree with Alston in this statement. I am much indebted to Mr. Alston for his minute description of the Mus in question, s. n. Mus terrae-reginae. If I had known that Gray’s leucopus has the tail shorter than head and body and the fur above dark reddishand not greyish-brown, I should certainly not have made a mistake in confounding these two distinct species. But I believe it quite impossible to recognize species if they are described so incompletely and inexactly as is the case with the greater part of Gray’s... |

| The Committee of the International Colonial Exhibition at Amsterdam has been kind enough to send to me a collection of Mammals made by Mr. F. von Feber during his residence in N. Celebes and W. Sumatra. The request was that I should subject the collection to a systematic review I feel sure that this review contains many facts interesting to zoologists, as it embraces certain very rare and partly unknown species and at the same time gives a very good idea of the peculiar Fauna of Celebes. The Mammals have been collected in the neighborhood of Loeboe Basong, Priaman, West-Sumatra, and in the vicinity of Amoerang, North-West-Celebes. |

| The African Squirrels have never been monographically studied, although a large number of more or less important descriptions of different species have been given, which are to be found in different periodicals. The late Temminck in his »Esquisses zoologiques sur la côte de Guiné. 1853” was the first to give a revision of the Squirrels from West-Africa known at that time. The late Gray in »the Annals and Magazine of Natural History, 1867” published a Synopsis of the African Squirrels and Huet described in his »Recherches sur les Écureuils Africains 1880” the Squirrels of the Paris Museum. These three publications are the principal sources. There are further several separate descriptions of species by Kerr, Ét. Geoffroy Saint-Hilaire, Desmarest, Smith, Fr.... |

| A rare constancy in color of the fur in some species, a nearly endless variety in other species and a very peculiar geographical distribution render the study of this beautiful group of Marsupials very difficult but at the same time highly interesting and attractive. A thourough study based upon large and well selected series from the most different and distant localities is the only way to surmount the very difficulties. No wonder therefore that so many naturalists have failed in their efforts to recognize and circumscribe the species composing this group. The Cuscus-species have half or more than half the prehensile tail destitute of hair and the second and third toes of the hind feet united in a common integument very nearly to the extremity. These two... |

| The Resident of Palembang, Sumatra, had the kindness to enrich our collections with four Mammals from different parts of his Residency; two are specimens of Gymnura Rafflesii, one is a Cynoyale Bennetti and the fourth a Herpestes brachyurus. The species are long-known ones, although not very numerous in the Musea; they therefore still are very welcome additions. The Controller of the Kikim reports: »that the forestiers »told him that the animal called Tampeline (Gymnura » Rafflesii) is rather rare in that country; these animals »are living two together in holes on the slope of a precipice or under the roots of large trees in the virgin »forest, they principally live on small animals (rats, insects »a. s. o.), though they are supposed to live as well on... |

| This beautiful greenish tinged Squirrel has been procured by Mr. G. J. A. Pool at the Stanley-falls, Congostate, in August 1905; Professor Dr. A. A. W. Hubrecht (Utrecht) had the kindness as to present it to our National Museum. It apparently is an animal belonging to a hitherto undescribed species; I describe it here under the specific title of the collector: Sciurus Poolii, n. sp. It is a wood-squirrel, known by the indigenes under the name Pania ya mti (Kiswahili-dialect), rather frequent, eaten by the Negros (observations made by Mr. Pool). |

| Mr. Bartels forwarded to me some small Mammals from Java, for identification. It appears that a Bat belongs to a hitherto not recognized species. This Bat, found at the top (10,000 feet) of the Pangerango-mountain, March 22. 1908, strongly reminds by its bright colours the splendid Kerivoula Weberi from Celebes, described by me in „Weber’s Zoologische Ergebnisse”, Band I, p. 129, and figured on Tab. XI (1890—91). When I described the latter, I had not extracted the skull of this type-specimen, and so the middle lower incisors made the impression of having each three cusps, like many other Kerivola-specimens; these incisors are so imbricated that, as a matter of fact, only three cusps are to be seen when the skull is in the flesh. Having, however, now... |

| In the family of the Pteropodidae there are three genera in which the claw to the index finger is wanting, viz. Cephalotes, Notopteris and Eonycteris. The first of these genera is represented by two, the others each by a single species. They are distributed in the following manner: Cephalotes peronii inhabits the islands of the Austro-Malayan subregion, while Cephalotes minor is to be found in New Guinea; Notopteris macdonaldii is limited to the Fiji-group and Aneiteum-island and Eonycteris spelaea is to be found in caves on the Indian continent (Burma). The Pteropodidae met with by the numerous travellers in the African continent belong without exception to the genera Epomophorus and Cynonycteris. Taking these facts into consideration I was greatly... |

| In my “Catalogue systématique des Mammifères, T. XII, 1888, p. 131” I recorded a small shrew from Surinam under the specific title pyrrhonota; till now the animal waits for a description. It seems that Shrews are very rare animals in Surinam, as I nowhere could hunt out another mentioned specimen; as far as I am aware the only Surinam-shrew has been exhibited by Lin. Gmelin, T. I, 1789, p. 114, under the name Sorex surinamensis. It is a pity that the history of our specimen is entirely unknown and the locality Surinam so very vague; this may be as it is, the shrew however differs from all hitherto described species, and I will describe it now under the well appropriate name bestowed upon it in 1888: Blarina pyrrhonota Jentink. „ . 4—4 1 — 1 2—2 3—3... |

| Mr. Edward Jacobson from Semarang (Java), one of the zealed correspondents of our Museum, communicated me the other day some observations made by himself on living animals. Especially of a high scientific interest seemed to me what he wrote concerning the habits and behavior of a specimen of the Scaly Anteater, Manis javanica; among his observations is one quite unknown till now, namely that the animal when frightened, emits a strong musk-smell. As far as I am aware no hunter or traveler made the same observation before. Dr. Büttikofer, at present Director of the Rotterdam Zoological Garden, had in Liberia numbers of living specimens of Manis tricuspis and M. longicaudata under observation, he however never has perceived the named smell. As it is a very... |

| The type-specimen of Buffon’s Fossane, Fossa Fossa (Schreber) had been presented in 1761 by Monsieur Poivre to the Cabinet du Roi: it was a stuffed skin, with the jaws and the bones of the legs. The animal measured 17 pouces from the tip of the nose to the origin of the tail, the tail measuring 8½ pouces. In Etienne Geoffroy St. Hilaire’s Catalogue (des Mammifères du Muséum national d’Histoire naturelle de Paris, 1803) on p. 112 there we find under n° CCXLI «l’individu original de la description de Buffon» of the Civetta fossa, la Civette fossane: however Geoffroy adds that this specimen has been given by Sonnerat, meanwhile Buffon’s type (see above) had been presented by Poivre! On my inquiry Monsieur de Pousargues from the Paris Museum had the kindness... |

| The profound and extensive studies upon the American Squirrels by Allen 1) and Alston 2), have made this group, we must confess it, one of the best known among the Mammals. At the same time however the named authors have shown that it is almost an impossibility to give a good and exact diagnosis of an American Squirrel, because the specimens of a given species differ, so to say, infinitely in the hairiness of the ears, which are tufted or not tufted, in the length and strength of the body, a. s. o. The difficulty increases as these variations are to be found not constantly in individuals from different localities, but as they often are present in individuals from the same locality and gathered on the same day or in the same season. And this is a rule with... |

| The type-specimen (an adult male with skeleton), collected by Beccari on one of the islands of the Arou-Archipelago and described by Peters and Doria in 1875 (Ann. Mus. Civ. Gen. VII) and at the same time the only known individual, has been a puzzle to all students of the Phalanger-group. It therefore is of the highest interest that I found in the Lorentz-collection the three above mentioned specimens, prima facie distinct from all hitherto seen individuals of the orientalis-group, but at the same time exactly agreeing with gymnotis Peters et Doria. During the past summer I could study the type in the Genoa Museum, by the loudness of the Director Marquis G. Doria, so that I am absolutely sure of the identification. It hardly can be supposed that specimens... |

| Mr. Oldfield Thomas has described in the Journal of the Asiatic Society of Bengal, 1888, p. 256, a very interesting and aberrant Pteromys-form under the name Eupetaurus cinereus. He remarked that in the Leyden Museum were not improbably a melanoid and a normal example of this species. This supposition he based upon quotations by Anderson in his well known »Yunnan Expedition”. As the species under consideration seems to be a very rare one, at least in zoological collections, it has its interest to know if the two named specimens in the Leyden Museum really belong to E. cinereus and — if so — how far the characteristics given by Thomas are constant. |

| The collection of Bats hereafter described has been presented to the Leyden Museum by our well known correspondent Dr. C. G. Young from Berbice, New Amsterdam, British Guyana. This collection tells us that, although our knowledge about the Bats may have increased during the latest years, much remains to be done before we can pretend to know exactly these most interesting creatures: especially the study of the South-American Bats is very difficult by lack of sufficient material. Therefore every addition may be called welcome. |

| Up to this day I knew only a single Mammal, Sciurus prevostii, from Billiton, a small island, situated between Borneo and Banka. As the islands between Sumatra and Borneo bear a peculiar scientific interest with regard to the distribution of the animals and to the hypothesis concerning the relation in prehistorical times between these two large islands, I was in sanguine expectations in receiving a letter from Dr. A. Vorderman (Batavia), containing the kind information that he had made a journey to Billiton in June 1888 and now presented the then collected animals to our Museum. And how great was my astonishment in finding in that collection no less than 10 species of Mammals from Billiton. So that we know at present eleven well-defined species from that... |
