SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

The shells, mentioned in the following communication, have come in the possession of the Leyden Museum at various times. Some of them have been acquired long ago, and were labelled with false names; other ones have been presented quite recently to the Museum. Most shells represent already known species; but having previously been recorded from other localities, their habitat might be of some interest. Mr. G. K. Gude has had the kindness of identifying those shells, for which I had no specimens or good figures at my disposal for comparison.

On a new variety of Ampullaria crassa Swainson from French Guyana

Ano: 1913

URL: http://www.repository.naturalis.nl/record/508397

The Gonini-Expedition, that explored in 1903 and 1904 some of the rivers, giving origin to the Marowijne or Maroni, as it is called by the French (see sketch of Surinam on p. 2 of this volume), made also a little excursion on French territory, and explored a part of Mount Cottica on the right bank of the Lawa. Here, at an altitude of 450 M., were collected some specimens of Doryssa hohenackeri Phil., of which species, although recorded from Surinam in general, no well-stated locality in our colony is known (see p. 35), and also three specimens of an Ampullaria, which apparently is related to the A. crassa Swains. from the Lawa, mentioned in my paper on the non-marine molluscs of Surinam (this volume pp. 1—46). With Mr. Sowerby, who had he kindness to...

Catalogus der Nederlandsche Mollusca van 's Rijks Museum van Natuurlijke Historie

Ano: 1914

URL: http://www.repository.naturalis.nl/record/509162

Als vervolg op den catalogus der land-, zoetwater- en brakwatermollusca, geef ik hier een lijst der zeemollusca van Nederland, in 's Rijks Museum van Natuurlijke Historie aanwezig op 1 September 1916. Onder de schelpen, die op onze stranden aanspoelen, vindt men vaak voorwerpen, die het voorkomen van fossielen hebben. Of het werkelijk fossielen zijn, is niet altijd uit te maken, daar die voorwerpen soms tot soorten behooren, die nog levend op onze kust, of inde Zuidelijke Noordzee voorkomen. Een vindplaats die vooral gekarakteriseerd is door de groote menigte van dergelijke voorwerpen, is het strand van Walcheren, bij Domburg. Ongetwijfeld zijn de meeste schelpen, die daar in dien toestand gevonden worden, werkelijk fossielen. Daarom vermeld ik hen in een...

The non-marine Molluscs of Surinam

Whilst the Mollusc-fauna of the Dutch colonies in the eastern hemisphere has been studied since very remote times, and its literature represents a considerable pile of very valuable papers, written by well-known conchologists and investigators of many parts of the world, the Dutch West-Indies, and especially Dutch Guyana or Surinam, are very little known in regard to their molluscs. As far as I know the only existing list of non-marine molluscs of Surinam is that given by the late Prof. Ed. von Martens in his „Binnenmollusken Venezuela’s”. That list excepted, it is only by chance, that one finds the habitat „Surinam” in a malacological paper: either in a note on newly acquired collections of shells, or in monographs of some families, or in books of...

Petricola pholadiformis Lam. on the Dutch Coast

Ano: 1914

URL: http://www.repository.naturalis.nl/record/508713

Since I published my paper on this subject (Notes Leyden Museum, Vol. XXXIV, 1912, p. 240), the following localities of our coast where this American mollusc also has been collected, have come to my knowledge: Vlissingen, isle of Walcheren; south-east of Domburg (see sketch of the coast of the Netherlands in the cited paper). Eastern-Schelde, between Ierseke and Tholen. Zandvoort, between Noordwijk and Petten. Terschelling, the island next to Vlieland in nord-east direction. Leiden Museum, Jan. 7, 1915.

Terwijl ik het voornemen heb om binnenkort in dit tijdschrift een overzicht te geven van alle in Nederland waargenomen Mollusca, en tevens van de daarop betrekking hebbende litteratuur, geef ik hier een lijst van de Mollusca, in Nederland verzameld, die in 's Rijks Museum van Natuurlijke Historie aanwezig zijn. Uit deze lijst, waarvan het hier volgend gedeelte de niet-marine vormen bevat, blijkt dat onze verzameling van inlandsche Mollusca nog verre van volledig is. Niet alleen zijn verscheidene soorten die in ons land voorkomen, nog niet aanwezig in 's Rijks Museum van Natuurlijke Historie, maar ook is het aantal localiteiten, waarvan het museum materiaal bezit, betrekkelijk gering en zijn er nog vele streken van ons vaderland niet vertegenwoordigd. Het...

On a peculiar mode of attaching of Siphonaria sipho, Sow

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...

Some species of Molluscs, new for Holland of rarely found there

Ano: 1913

URL: http://www.repository.naturalis.nl/record/509346

Some time ago Mr. W. C. van Heurn, student at the Leyden University, presented a very large collection of shells, all of them found by himself in various localities of our country, to the Leyden Museum. Among them I discovered specimens of three species, not recorded as belonging to the Dutch fauna. 1. Lacuna divaricata Fabr. A few specimens, collected June 1909 on the coast of Texel. Mr. M. M. Schepman, the well-known conchologist, wrote to me this being only the second time he saw Dutch specimens.

On two forms of Amphidromus semifrenatus, Marts

Ano: 1912

URL: http://www.repository.naturalis.nl/record/509287

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...

Helix aspersa Müller in Holland

Ano: 1913

URL: http://www.repository.naturalis.nl/record/508843

In „Nachrichtsblatt der Deutschen Malakozool. Gesellsch. 1910, p. 134” Mr. V. Franz (Helgoland) gives a note on the occurrence of Helix aspersa in Holland at Vlissingen. He suggests that the animals have been transported fortuitously to that locality. Now I will not discuss the possibility this having been the case here, in the neighborhood of the harbour, where the snails can have been brought with ships from England or Belgium. But the occurrence of Helix aspersa at Vlissingen is not at all curious, as it is considered since many years as belonging to the Dutch fauna. In his list of Dutch molluscs, published in 1858, Mr. Maitland ¹) cites already Helix aspersa, and gives various localities in Holland, including also the isle of Walcheren, where...

Petricola pholadiformis Lam. on the Dutch coast

Ano: 1912

URL: http://www.repository.naturalis.nl/record/509047

In 1907 Mr. Caesar R. Boettger 1) called attention to the fact that this species, an inhabitant of the North-American seas, since the last decennium of past century is spreading on the European coast. In Europe it was found first in England at Cricksea on the river Crouch, in July 1890 2), and on the Lincolnshire coast 3). The following years brought further references about the occurrence of Petricola pholadiformis on the English coast 4). At present the localities where it is found, stretch from Shellness, near Sandwich, Kent, in the south, to Mablethorpe, Lincolnshire, in the north. Mr. Loppens 5) was the first to notice this species on the continent; he found it near Nieuwpoort on the coast of Belgium, in 1899. Very soon afterwards other localities...

The Land- and Freshwater-Molluscs of the Dutch West-Indian Islands

Ano: 1912

As I stated in my paper on the non-marine Molluscs of Surinam (p. 1 of this volume), our knowledge of the Mollusc-fauna of the Dutch colonies in America is only very little. In that paper I exposed all that is known, up to the present time, of the non-marine shell-bearing molluscs of Surinam; at present I will do the same with regard to the other Dutch colony in America, viz. the colony of Curaçao. This colony consists of two groups of small islands, all placed under one Governor, residing in the principal island Curaçao, which has given its name to the whole colony. One group, near the coast of Venezuela, consists of the islands Aruba, Curaço, Little Curaçao, Bonaire and Little Bonaire. The other group, situated in the northern part of the chain of the...
