DR. G. GRIJNS f f DEEL 29 VERHANDELING 1 REPORT ON A COLLECTION OF RECENT SHELLS FROM OBI AND HALMAHERA (MOLUCCAS) BY DR. C. H. OOSTINGH H. VEENMAN &ZONE N —WAGENINGE N — 1925 ^cSte GEDRUKTTE RALGEMEEN ELANDSDRUKKERI J The present paper deals with a collection of recent shells, chiefly marine, from the islands of Obi Major and Halmahera (or Gilolo) in the Moluccas (East Indian Archipelago). This collection forms part of the conchological collections kept in the Geological Museum of the Agricultural University at Wageningen (Holland). The shells from Halmahera have been collected on the East coast by the Rev. Maan, missionary at the mission Buli- and Weda-bay, E. coast of Halmahera, The shells from Obi Major were collected on the shores by Mrs. Ham when accompanying Prof. S. P. H a m, now in Wageningen, during a stay at that island in 1899. As I thought it useful to give a summary of the whole littoral marine and submarine molluscan fauna of the neighbourhood, I have included all the shell-bearing species which have hitherto been recorded from the ObiIs . and from Halmahera and surroun­ ding islands 1). Owing to the kindness of Dr. Fr. Haas, I was able to prepare part of this paper at the Senckenberg Museum in Frankfurt-on- Main, where I could avail myself of the excellent library. As to the part of this work made in Wageningen, I am much indebted to Prof, van Baren for his help in procuring the most indis­ pensable literature. Mr. J. J. Ve r wi jn e n has greatly obliged me by the loan of books from the rich library of Teyler's Museum. In conclusion, I have to express my thanks to Miss W. S. S. van Benthem Jutting, of the Zoological Museum at Amsterdam, and to Dr. Ed. La my , of the Museum d'Histoire naturelle in Paris, who have kindly assisted me in the identifi­ cation of certain critical specimens. A summary of previous work on the marine Mollusca of the northern Moluccas may now be given. Between 1860 and 1865 the region under consideration has been explored by Dr. H. A. Bernstein who collected for the 1) The names (and synonymy) of species not in the collection are printed in smaller type. 4 Leyden Museum at Halmahera, Rau, Morotai, Ë a ch an and the Obi Is.1). A considerable number of Prosobranchia and one species of Chiton, collected by him, were listed in the Catalogue of the Leyden Museum by HORST and SCHEPMAN (63). Moreover some shells from T e r n a t e, collected by Dr. Semmelink, were mentioned in that catalogue. In 1862 Halmahera and the islands west of it (the Moluccas proper) were explored for shells by Professor EDUARD VON MARTENS. Collections were made by him at Halmahera, Ternate, Tidore, Mareh, Motir, Makian, Kajoa, (Great-) T a w a 1 i, K em a , and B a ch a n. Apart from the terrestrial Mollusca, the results of his investigations were published in his monographs of Neritina (104), Navicella (106), and Nerita (108) in the Conchylien-Cabinet, in MAX WEBER's „Zoologisch e Ergebnisse einer Reise in Niederländisch Ost- Indien" (109), and in the „Rumphius Gedenkboek" (110). In 1889 Dr. Adolf Strubell collected some shells at B a ch a n, which were described by O. BOETTGER (13). Prof. W. KÜKENTHAL in 1893—94 made zoological collections at Halmahera, Ternatej and Ba c h an . The results of his voyage were published in a series of articles by several zoologists. Some articles deal with testaceous Mollusca (191) (192) (193). As to the Mollusca collected by the Siboga expedition (1899—1900), I have included the shells collected near Laiwui (Obi Major), and north of Salomakiëe- island near the southern peninsula of Halmahera. A consi­ derable number of Gastropoda were recorded from these localities by M. M. SCHEPMAN (155), moreover some Chitons by H. F. NlERSTRASZ (203), and a single representative of the family Pectinidae by DAUTZENBERG and BAVAY (39). In 1910 PH. DAUTZENBERG (38) listed a collection of marine shells sent from Halmahera to the „Musée Océanographique" at Monaco. N.B.: In the systematic portion authors' names are printed in capitals, names of scientific travellers who collected molluscs are in ordinary type. The numbers in parentheses following authors' names refer to corresponding numbers in the Bibliography given at the end of this paper. *) All the islands mentioned here have been indicated on the appended sketch-map. 3Ldo/a£?

ABSTRACT The veined rapa whelk (Rapana venosa) is widely consumed in China. Nevertheless, it preys on KEYWORDS oceanic bivalves, thereby reducing this resource worldwide. Its larval metamorphosis comprises a transition from miRNA pelagic to benthic form, which involves considerable physiological and structural changes and has vital roles in its metamorphic natural populations and commercial breeding. Thus, understanding the endogenous microRNAs (miRNAs) that transition drive metamorphosis is of great interest. This is the first study to use high-throughput sequencing to examine the gastropod alterations in miRNA expression that occur during metamorphosis in a marine gastropod. A total of 195 differ- larval entially expressed miRNAs were obtained. Sixty-five of these were expressed during the transition from pre- competent to competent larvae. Thirty-three of these were upregulated and the others were downregulated. Another 123 miRNAs were expressed during the transition from competent to postlarvae. Ninety-six of these were upregulated and the remaining 27 were downregulated. The expression of miR-276-y, miR-100-x, miR-183-x, and miR-263-x showed a .100-fold change during development, while the miR-242-x and novel-m0052-3p expression levels changed over 3000-fold.

  • Training Workshop on the Taxonomy of Marine Molluscs Mauritius, October 2017
    Training workshop on the taxonomy of marine molluscs Mauritius, October 2017 Introduction IOC Biodiversity and MOI organized a regional workshop in Mauritius in October 2017 for 4 days. The main objective of the workshop were (i) to train regional marine biologists to the taxonomy of molluscs, (ii) to build capacities in the description and identification of molluscs, (iii) to assess the mollusc biodiversity and its evolution in tropical marine ecosystems. Figure 1: Le Bouchon sampling site Material and Methods About 20 participants attended the workshop with about half of them from Mauritius and the others from Madagascar, Comoros, Kenya and Tanzania. The workshop was led by an Australian expert. The workshop followed these 3 steps: - Day 1: Formal classroom training about taxonomy, molluscs and shells features. Generals information slide about molluscs were projected. - Day 2: Field sampling in Mauritius at Le Bouchon (South-east coast). The sampling was performed in various biotopes provided at the location: beach, rocky shore, mangrove and lagoon. Lagoon itself provided various environments (live coral, rubbles, sand, grass, silt). Some samplers were on foot and other snorkelling. The only method used was hand picking of shells during one hour. Shells were either dead (empty or crabbed) or alive with limitation of 1 specimen per species. The objective of the sampling was not quantitative but qualitative. The shells have been washed and put to dry in the lab after the field collection. - Day 3-4: Analysis of the samples sorted and numbered by kind and appearance. Participants had to write a description of as many species as they could in group of 2-3.

  • THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
    August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject.

ABSTRACT The family Neritidae has representatives in tropical and subtropical regions that occur in a variety of environments, and its known fossil record dates back to the late Cretaceous. However there have been few studies of molecular phylogeny in this family. We performed a phylogenetic reconstruction of the family Neritidae using the COI (722 bp) and the 16S rRNA (559 bp) regions of the mitochondrial genome. Neighbor-joining, maximum parsimony and Bayesian inference were performed. The best phylogenetic reconstruction was obtained using the COI region, and we consider it an appropriate marker for phylogenetic studies within the group. Consensus analysis (COI +16S rRNA) generally obtained the same tree topologies and confirmed that the genus Nerita is monophyletic. The consensus analysis using parsimony recovered a monophyletic group consisting of the genera Neritina , Septaria , Theodoxus , Puperita , and Clithon , while in the Bayesian analyses Theodoxus is separated from the other genera.
