Received: 17 December 2019; Accepted: 11 January 2020; Published: 16 January 2020 Abstract: Mexico is one of the three areas of the world with the greatest terrestrial and cultural biological diversity. The diversity of Mexican medicinal flora has been studied for a long time and several bioactive compounds have been isolated. The investigation of marine resources, and particularly the potential of Mexican marine resources, has not been intensively investigated, even though the Yucatan Peninsula occupies 17.4% of the total of the Mexican coast, with great biological diversity in its coasts and the ocean. There are very few studies on the chemistry of natural products from marine organisms that were collected along the coasts of the Yucatan Peninsula and most of them are limited to the evaluation of the biological activity of their organic extracts. The investigations carried out on marine species from the Yucatan Peninsula resulted in the identification of a wide structural variety of natural products that include polyketides, terpenoids, nitrogen compounds, and biopolymers with cytotoxic, antibacterial, antifouling, and neurotoxic activities. -

Foregut anatomy of the Cochlespirinae (Gastropoda, Conoidea, Turridae) Alexandra I. MEDINSKAYA A. N. Severtzov Institute of Problems of Evolution, Leninsky Prospect 33, Moscow 117071 (Russia) Medinskaya A. I. 1999. — Foregut anatomy of the Cochlespirinae (Gastropoda. Conoidea. Turridae). Zoosystema2\ (2): 171-198. ABSTRACT The foregut anatomy of 20 species, belonging to eight genera, of the sub family Cochlespirinae is described. A cladistic analysis based on several most important characters (morphology of proboscis, position of buccal sphinc ters, histology of venom gland, position of the venom gland opening, struc ture of muscular bulb, and morphology of radular teeth) revealed three more or less well-defined groups within the subfamily. The main feature characte rizing the subfamily as a whole and separating groups within it, appeared to be the structure of venom gland and its muscular bulb. The subgenus KEYWORDS Cochlespirinae, Sibogasyrinx of the genus Leucosyrinx was shown to deserve a genus status.

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. -

Despite the plethora of studies, geographic patterns of diversity in deep sea remain subject of speculation. This study considers a large dataset to examine the faunal change and depth-diversity gradient of prosobranch molluscs in the Porcupine Seabight and adjacent Abyssal Plain (NE Atlantic). Rates of species succession (addition and loss) increased rapidly with increasing depth and indicated four possible areas of faunal turnover at about 700, 1600, 2800 and 4100 m. Depth was a significant predictor of diversity, explaining nearly a quarter the variance. There was a pattern of decreasing diversity downslope from 250 m to 1500–1600 m, followed by an increase to high values at about 4000 m and then again, a fall to 4915 m. Processes causing diversity patterns of prosobranchs in the Porcupine Seabight and adjacent Abyssal Plain are likely to differ in magnitude or type, from those operating in other Atlantic areas. Introduction An increasing focus for biodiversity research in the deep sea has been to test for the existence of large-scale gradients in the diversity of marine soft- sediment fauna in deep sea (e.g. -

E-mail: [email protected] SUMMARY: Samples of a soft-bottom community from the continental slope of Campos Basin, off southeast Brazil, were obtained between 2001 and 2003 by the Research Vessel “Astro-Garoupa” with a 0.25 m2 box corer or by dredging with a Charcot dredge. A total of 177 samples were taken at depths ranging from 700 to 1950 m. Mollusks were present at all of the stations and among Gastropoda the Turridae showed the highest diversity. Within the family Cochlespirinae we found: Leucosyrinx tenoceras (Dall, 1889), L. verrillii (Dall, 1881), expanding the known distribution of the latter species farther south, and L.? subgrundifera (Dall, 1888), which is the first record of this species for the South Atlantic and the shallowest depth at which it has ever been found. Within the family Drilliinae we found Splendrillia centimata (Dall, 1889), also the first record of this species for the South Atlantic and its shallowest depth. Within the subfamily Oenopotinae we describe here three new species in the genus Oenopota Mörch, 1852: O. seraphina n. sp., O. diabula n. sp. and O. carioca n. sp.

Comparative Anatomy of Four Primitive Muricacean Gastropods: Implications for Trophonine Phylogeny
^/ -S/ COMPARATIVE ANATOMY OF FOUR PRIMITIVE MURICACEAN GASTROPODS: IMPLICATIONS FOR TROPHONINE PHYLOGENY M. G. HARASEWYCH DEPARTMENT OF INVERTEBRATE ZOOLOGY NATIONAL MUSEUM OF NATURAL HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C. 20560, U.S.A. ABSTRACT The main features of the shell, head-foot, palliai complex, alimentary and reproductive systems of Trophon geversianus (Pallas), Boreotrophon aculeatus (Watson), Paziella pazi (Crosse), and Nucella lamellosa (Gmelin) are described, and phonetic and cladistic analyses based on subsets of these data presented. Similarities in shell morphology revealed by phenetic studies are interpreted as being due to convergence, and are indicative of similar habitats rather than of close phylogenetic relationships. Convergences are also noted in radular and stomach characters. Cladistic analyses of anatomical data support the following conclusions: 1 ) Thaididae are a primitive and ancient family of muricaceans forming a clade equal in taxonomic rank with Muncidae; 2) Within Muricidae, P. pazi more closely resembles the ancestral muricid phenotype than any trophonine; 3) Trophoninae comprise a comparatively recent monophyletic group with differences due to a subsequent austral adaptive radiation. The Muricidae are considered to be the most primitive and D'Attilio, 1976:13) a personal communication from E.

A ki- advány – Magyarországi pleisztocén és recens malakológiai bibliográfia címen – igyekezett áttekintést adni mindazokról a munkákról, melyek Magyarország területén végzett kutatá- sok eredményeit tartalmazták. Az összeállítás Magyarország alatt az adott munka megjele- nési idejének megfelelő ország területét vette alapul. Jelen összeállítás is követi ezt az alap- elvet, de a fentieken túl tartalmaz minden olyan munkát is, mely magyar szerzők nevéhez fűződően hazánkon kívüli területek malakológiai anyagának feldolgozását tartalmazza, vagy valamilyen formában kapcsolatba került a magyarországi malakológiai kutatásokkal (pl. VERDCOURT 2004). Az 1983-ban megjelent kiadványt követően egyre gyakrabban jelentkezett az igény, hogy az időközben fellelt, s a kötetből kimaradt régebbi irodalmi adatok, illetve az eltelt időszak- ban elvégzett munkák összegzése is jelenjen meg. Ennek az igénynek igyekezett eleget tenni az 1991-ben PERJÉSI György és HORVÁTH Csaba által összeállított munka, „Magyarországi pleisztocén és recens malakológiai bibliográfia (Pótlás)” a Malakológiai Tájékoztató 10. (1991) kötetében, majd ugyancsak ez a szerzőpáros készítette el az időközben megjelent újabb dolgozatok bibliográfiáját: „Magyarországi pleisztocén, quarter és recens malakológiai bibliográfia 1980-1990.” (sic!) címmel a Malakológiai Tájékoztató 11. (1992) kötetében. A fentiekben megjelent munkák óta eltelt közel negyed század ismét felvetette az igényt, hogy készüljön egy új, részben eltérő szerkesztési elveket követő munka, melynek céljai közt szerepel, hogy egyrészt összevonja a MERÉNYI, PERJÉSI & HORVÁTH féle össze- állításokat, másrészt az anyagot 2004-ig bezáróan kiegészítse az időközben megjelent dol- gozatokkal. -

The diverse and unique shell shapes are interesting to draw. The easiest medium to describe the shape of a mollusk is in two dimensions. This study aims to identify various images of mollusks in two-dimensional print media such as cloth, paper and plates. Based on the 10 sources of photos analyzed, 56 species of mollusks from 38 families were identified. The Gastropod class dominates with 45 species from 31 families, followed by Bivalves with 7 species from 5 families, then Cephalopods with 4 species from 2 families. Some of the problems found are the shape and proportion of images that different with specimens, some inverted or cropped images, different direction of rotation of the shells with specimens, and different colour patterns with specimens. Biological and distributional aspects of several families will be discussed briefly in this paper.
