PRELIMH1ARY CIIECKLIST nF TilE GPSTROPnDS nF r,UP,M Capt. Plexander Roth, .Jr. Sea Grant Publication IJGSG-76-03 UNIVERSITY OF r,UAM MP.RINE LPBnRAT~py Technical Report No. 27 flay 1976 This publication was printed under the auspices of the University of Guam Sea Grant Program (Grant No. 04-5-158-45) through an award fr~ the National Oceanographic and Atmospheric Administration, Office of Sea Grant Programs, Department of Commerce. INTRODUCTION This report is a listing of the gastropods found around the island of Guam. Many of these may be found in other islands of the Marianas, but it is not the intent of the author to identify this listing with any area other than Guam. The names are listed in alphabetical order by species, since their generic names are often disputed by v ~ rious authors . Whenever possible the latest official name~ author, and date has been used. Synonyms are shown for many of them. However. the list of synonyms should not be considered as c~plete. Parenthesis for authors names has been omitted for the synonyms. The listing was compiled from three basic sources--published text material, as per the bibliography; from lists of shells in private collections; and from conversations with knowledgeable canchologists in the area. Particular mention should be made of the assistance given by the late Mr. B. Compton and Mr. H. Ward, and by Hr. T. Montgomery, all of whom resided on Guam. The author of this project is an amateur cochologist who undertook it purely for his own satisfaction and to increase his knowledge re­ garding the gastropods of Guam. It is also 1 ikely that errors may be found in those listed. The nearly 950 species listed should be a starting point from which our entire knowledge of the gastropods of Guam can advance. Finally, special thanks are extended to the Marine Laboratory of the University of Guam for their assistance in preparing this listing and to the Sea Grant Project which helped it through its publication.

Abstract Composition, diversity and abundance of rocky intertidal mollusks and their relationship with the environmental parameters, viz. water quality, total organic matter and calcium carbonate were determined. A total of 43 species were identified, of which 41 species belong to Class Gastropoda under 18 families and 2 species were categorized under Class Bivalvia from 2 families. Using several diversity indices, results revealed high diversity and equitability values in the 2 sampling sites. Moreover, comparison of the mollusks abundance between the 2 sampling stations showed station 2 to be dominantly abundant with Cerithium stercusmuscarum comprising almost one-third of the total population. Canonical Correspondence Analysis showed that total organic matter and calcium carbonate in the sediment may have influenced the abundance of mollusk assemblage in station 2. The results obtained from the study are vital in order to strongly support the need to continue monitoring the Lugait marine sanctuary and its nearby surroundings.

E-mail: [email protected];[email protected] ABSTRACT: KiEL, S. & BANDEL, K. 2001. Trochidae (Archaeogastropoda) from the Campanian of Torallola in nothern Spain. Acta Geologica Polonica, 51 (2),137-154. Warszawa 30 species of the archaeogastropod family Trochidae are described from the Campanian of the southern Pyrenees, 15 of them are new. The new genus Amphigibbula is introduced and the genus Chilodontoidea is renamed as Hudledonta. Apparently several trochid lineages with living species can be traced back into the Late Cretaceous. This regards the Eucyclinae, Margaritinae, and Solariellinae, and the Tegulinae with some reservations. Among the groups examined here, only the members of the Trochinae appear to be of rather different character than their mod­ ern representatives. The fossil record of the Umboniinae can go far beyond that of the Late Cretaceous and connect even to Palaeozoic genera. The 15 new species are: Eucyciomphalus reminiscencius, Calliotropis torallolensis, Calliotropis seguris, Ilerdus pyrenaeus, Eucycioscala cretacea, Hudledonta nicolae, Danilia kosslerae, Margarites kasei, Margarites nieiseni, Margarites kowalkei, Tectus quinteroi, Thoristella marshalli, Suavotrochus ponsi, Ethalia vinxae, and Protorotella herberti. Kewwords: Cretaceous, Campanian, Trochidae, Northern Spain. INTRODUCTION is not infrequently the case in the carbonate environment, rock diagenesis usually has resulted in a hard limestone, The Late Cretaceous was a time when numerous from which fossils are difficult to extract. modern gastropod groups made their first appearance The sediments of the Puimanyons Olisthostrom and subsequently radiated (SOHL 1987).

Read Full License Page 1/18 Abstract Background Growth rate is considered one of the most important factors in the farming of Haliotis midae and somatic growth rates decline after abalone reach sexual maturity. Articial diets are suspected to accelerate maturation, in particular when soya meal is used as a protein source, because of this plant’s high concentration of phytoestrogens. Results We fed two articial diets and a natural diet, kelp. The rst articial diet had shmeal as its main source of protein while the other, Abfeed® S34, replaced some of the sh proteins with soya meal. The effect of diet on the gonad development of 27-month-old farmed Haliotis midae, raised at two stocking densities, was analysed. For each gonad sample the development phase was determined based on both histological criteria and the gonad bulk index (GBIn). The hypothesized link between dietary protein source and gonad development could not be established by either morphological criteria or GBIn.

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.

Present address: The Kyoto University Museum, Yoshida Honmachi, Sakyo-ku, Kyoto 606-8501, Japan (email: [email protected]) Received December 19, 2005; Revised manuscript accepted May 26, 2006 Abstract. Cerithiform gastropods possess high-spired shells with small apertures, anterior canals or si- nuses, and usually one or more spiral rows of tubercles, spines or nodes. This shell morphology occurs mostly within the superfamily Cerithioidea. Several morphologic characters of cerithiform shells are adap- tive within five broad functional areas: (1) defence from shell-peeling predators (external sculpture, pre- adult internal barriers, preadult varices, adult aperture) (2) burrowing and infaunal life (burrowing sculp- tures, bent and elongated inhalant adult siphon, plough-like adult outer lip, flattened dorsal region of last whorl), (3) clamping of the aperture onto a solid substrate (broad tangential adult aperture), (4) stabilisa- tion of the shell when epifaunal (broad adult outer lip and at least three types of swellings located on the left ventrolateral side of the last whorl in the adult stage), and (5) righting after accidental overturning (pro- jecting dorsal tubercles or varix on the last or penultimate whorl, in one instance accompanied by hollow ventral tubercles that are removed by abrasion against the substrate in the adult stage). Most of these char- acters are made feasible by determinate growth and a countdown ontogenetic programme.

Here we describe two morphs from the complex as new species. Using morphological comparisons, we show the new species to be closely related but distinct from each other and from M. brockii. Distributed across north-western Australia, M. ffo sp. nov. is known from Exmouth, Western Australia to the Wessel Islands, Northern Territory, whereas M. hermanita sp. nov. is known only from Madang, Papua New Guinea. Differences between the two species include colouration, the size of the receptaculum seminis and some distinction in the jaws. Unravelling the entire complex will take much wider geographic sampling, and will require recollection from the type locality of M. brockii. This group is yet another example of a purportedly widespread aeolid species comprising a complex of species.
