The last sample was taken at a site known as “The Rose Garden” off north− eastern Iceland and yielded a large number of two species of Proneomenia (Mollusca, Aplacophora, Solenogastres, Cavibelonia, Proneomeniidae). We examined isolated scler− ites, radulae, and histological section series for both species. The first, Proneomenia sluiteri Hubrecht, 1880, was originally described from the Barents Sea. This is the first record of this species in Icelandic waters. However, examination of aplacophoran lots collected dur− ing the earlier BIOICE campaign revealed additional Icelandic localities from which this species was collected previously. The second represents a new species of Proneomenia, which, unlike other known representatives of the genus, broods juveniles in the mantle cav− ity. We provide a formal description, proposing the name Proneomenia custodiens sp. n. Interestingly, the sclerites of brooded juveniles are scales like those found in the putatively plesiomorphic order Pholidoskepia rather than hollow needles like those of the adults of this species. -

PHYLOGENY AND HISTORICAL BIOGEOGRAPHY OF LIMPETS OF THE ORDER PATELLOGASTROPODA BASED ON MITOCHONDRIAL DNA SEQUENCES TOMOYUKI NAKANO AND TOMOWO OZAWA Department of Earth and Planetary Sciences, Nagoya University, Nagoya 464-8602,Japan (Received 29 March 2003; accepted 6June 2003) ABSTRACT Using new and previously published sequences of two mitochondrial genes (fragments of 12S and 16S ribosomal RNA; total 700 sites), we constructed a molecular phylogeny for 86 extant species, covering a major part of the order Patellogastropoda. There were 35 lottiid, one acmaeid, five nacellid and two patellid species from the western and northern Pacific; and 34 patellid, six nacellid and three lottiid species from the Atlantic, southern Africa, Antarctica and Australia. Emarginula foveolata fujitai (Fissurellidae) was used as the outgroup. In the resulting phylogenetic trees, the species fall into two major clades with high bootstrap support, designated here as (A) a clade of southern Tethyan origin consisting of superfamily Patelloidea and (B) a clade of tropical Tethyan origin consisting of the Acmaeoidea. Clades A and B were further divided into three and six subclades, respectively, which correspond with geographical distributions of species in the following genus or genera: (AÍ) north eastern Atlantic (Patella ); (A2) southern Africa and Australasia ( Scutellastra , Cymbula-and Helcion)', (A3) Antarctic, western Pacific, Australasia ( Nacella and Cellana); (BÍ) western to northwestern Pacific (.Patelloida); (B2) northern Pacific and northeastern Atlantic ( Lottia); (B3) northern Pacific (Lottia and Yayoiacmea); (B4) northwestern Pacific ( Nipponacmea); (B5) northern Pacific (Acmaea-’ânà Niveotectura) and (B6) northeastern Atlantic ( Tectura). Approximate divergence times were estimated using geo logical events and the fossil record to determine a reference date. -

A Blind Abyssal Corambidae (Mollusca, Nudibranchia) from the Norwegian Sea, with a Reevaluation of the Systematics of the Family
A BLIND ABYSSAL CORAMBIDAE (MOLLUSCA, NUDIBRANCHIA) FROM THE NORWEGIAN SEA, WITH A REEVALUATION OF THE SYSTEMATICS OF THE FAMILY ÁNGEL VALDÉS & PHILIPPE BOUCHET VALDÉS, ÁNGEL & PHILIPPE BOUCHET 1998 03 13. A blind abyssal Corambidae (Mollusca, Nudibranchia) SARSIA from the Norwegian Sea, with a reevaluation of the systematics of the family. – Sarsia 83:15-20. Bergen. ISSN 0036-4827. Echinocorambe brattegardi gen. et sp. nov. is described based on five eyeless specimens collected between 2538 and 3016 m depth in the Norwegian Sea. This new monotypic genus differs from other confamilial taxa in having the dorsum covered with long papillae and a radula formula n.3.1.3.n. The posterior notch in the notum and gill morphology, which have traditionally been used as generic characters in the family Corambidae, are considered to have little or no taxonomical value above species level. Instead of the currently described 11 nominal genera, we recognize as valid only Corambe and Loy, to which is now added Echinocorambe. Loy differs from Corambe in the asym- metrical lobes of the posterior notal notch and the presence of spicules in the notum. All other nominal genera are objective or subjective synonyms of these two.

Descripción De Nuevas Especies Animales De La Península Ibérica E Islas Baleares (1978-1994): Tendencias Taxonómicas Y Listado Sistemático
Graellsia, 53: 111-175 (1997) DESCRIPCIÓN DE NUEVAS ESPECIES ANIMALES DE LA PENÍNSULA IBÉRICA E ISLAS BALEARES (1978-1994): TENDENCIAS TAXONÓMICAS Y LISTADO SISTEMÁTICO M. Esteban (*) y B. Sanchiz (*) RESUMEN Durante el periodo 1978-1994 se han descrito cerca de 2.000 especies animales nue- vas para la ciencia en territorio ibérico-balear. Se presenta como apéndice un listado completo de las especies (1978-1993), ordenadas taxonómicamente, así como de sus referencias bibliográficas. Como tendencias generales en este proceso de inventario de la biodiversidad se aprecia un incremento moderado y sostenido en el número de taxones descritos, junto a una cada vez mayor contribución de los autores españoles. Es cada vez mayor el número de especies publicadas en revistas que aparecen en el Science Citation Index, así como el uso del idioma inglés. La mayoría de los phyla, clases u órdenes mues- tran gran variación en la cantidad de especies descritas cada año, dado el pequeño núme- ro absoluto de publicaciones. Los insectos son claramente el colectivo más estudiado, pero se aprecia una disminución en su importancia relativa, asociada al incremento de estudios en grupos poco conocidos como los nematodos. Palabras clave: Biodiversidad; Taxonomía; Península Ibérica; España; Portugal; Baleares.

ABSTRACT Title of Dissertation: PATTERNS IN
ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range. -
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. -

Silica Biomineralization in the Radula of a Limpet
Zoological Studies 46(4): 379-388 (2007) Silica Biomineralization in the Radula of a Limpet Notoacmea schrenckii (Gastropoda: Acmaeidae) Tzu-En Hua and Chia-Wei Li* Institute of Molecular and Cellular Biology, College of Life Sciences, National Tsing Hua University, Hsinchu 300, Taiwan (Accepted November 6, 2006) Tzu-En Hua and Chia-Wei Li (2007) Silica biomineralization in the radula of a limpet Notoacmea schrenckii (Gastropoda: Acmaeidae). Zoological Studies 46(4): 379-388. The radulae of limpets are regarded as an ideal experimental material for studying biologically controlled mineral deposition, because they possess teeth in dif- ferent mineralization stages. The pattern of silica precipitation in the limpet, Notoacmea schrenckii (Gastropoda: Acmaeidae), was elucidated in this study using transmission electron microscopy (TEM), electron diffraction, energy-dispersive X-ray (EDX) analysis, and inductively coupled plasma mass spectrometry (ICP- MS). The ICP-MS elemental analysis showed that iron and silica both infiltrate into the radula in early stages of tooth development. Electron-dense granules in a nanometer size range were observed in ultrathin sections of tooth specimens in early mineral-deposition stage; electron diffraction analysis indicated that silica is the prima- ry component of these granules. TEM images revealed the intimate association between silica granules and the organic matrix, which implies that the organic matrix may take a more-active role in catalysis besides mere- ly functioning as a physical constraint during mineral deposition. Exposure of the tooth cusp to NH4F treatment and the appearance of silica spheres after the addition of silicate suggest that the organic molecules embedded within the minerals may assist silica precipitation. -
