The names of museum in the labels are “Rijksmuseum van Geologie en Mineralogie”, “Rijksmuseum van Geologie Leiden”, or “Rijks Geologisch-Mineralogisch Museum Leiden”. Labels in Japanese letters: The limited number of specimens are accompanied by Japanese labels. In most cases, labels are directly pasted on specimens. Names are written in Katakana letters only (e.g. Fig. 1E) or both in Chinese and Katakana letters (e.g. Figs. 1B, 3C, 3F). Identification of a few specimens in Japanese label is different from current our recognition and interesting. “Ryôkotsu” in Figs. 3F and 3H means dragon bones, but they are actually fragments of molluscan shells and eroded mammalian bones, respectively. In China, fossil vertebrate bones are called “Longgu” which is written in the same Chinese characters as “Ryôkotsu” in Japan, and have been used as a crude medicine. “Mimizu-ishi” in Fig. 2E stands for an earthworm stone, and winding tubes on the rock are bore holes of boring bivalve (“Teredo” sp.) with interior lining. Other fossils were precisely identified at phylum or class level. Examples are fossil fish (“Sekigyo”: Fig. 1B), fossil of wood (“Moku-kwaseki”: Fig. 4A), stone clam (“Ishi-hamaguri”: Fig. 11A), and fossil of heart urchin (“Kaien-no-kwaseki”: Fig. 3A). Molluscan specimens in Siebold fossil collection The molluscs in the Siebold fossil collection consist of more than 40 species as described below (Figs. 5-14). This number, however, does not contain the shell fragments in sandstone (Figs. 1D-G, 2A). In the following accounts, the depository of the specimens is in the mineralogical collection in Naturalis, unless otherwise mentioned.

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.

In my previous paper (ARAKAWA '62), I have already given a general account on the molluscan faeces at the present level of our knowledge in this field to­ gether with my unpublished data, and so in the first part of this serial work, I am going to describe and illustrate in detail the morphological characters of faecal pellets of molluscs collected in the Inland Sea of Seto and its neighbour­ ing areas.

  • Identifying Gastropod Spawn from DNA Barcodes: Possible but Not Yet Practicable

DNA barcoding has been touted as an important tool for linking life-history stages of the same species. To test the current efficacy of DNA barcodes for identifying unknown mollusk life stages, 24 marine gastropod egg capsules were collected off the Philippines in deep water and sequenced for partial fragments of the COI, 16S and 12S mitochondrial genes. Two egg capsules of known shallow- water Mediterranean species were used to calibrate the method. These sequences were compared to those available in GenBank and the Barcode of Life Database (BOLD). Using COI sequences alone, only a single Mediterranean egg capsule was identified to species, and a single Philippine egg capsule was identified tentatively to genus; all other COI sequences recovered matches between 76% and 90% with sequences from BOLD and Gen- Bank.

The geography or habitats in river estuaries differ depending on the energy from the tide, waves, and river; therefore, the biota inhabiting river estuaries vary depending on the river estuary type. In view of this, for effective conservation in river estuaries, there is a need for information about potential habitats and biota based on objective data about the river estuary type. The objective of this study thus was to classify river estuaries by their molluscan fauna and physical indicators to reveal the relationship between molluscan fauna and the physical environment. The classification results using physical indicators indicated three types of river estuaries (wave energy-dominated group, tide energy-dominated group, and low tide and wave energy group). This classification result was similar to the classification of molluscan fauna.

  • Temperature-Related Diversity of Shell Colour in the Intertidal Gastropod Batillaria
    TEMPERATURE-RELATED DIVERSITY OF SHELL COLOUR IN THE INTERTIDAL GASTROPOD BATILLARIA OSAMU MIURA1'2, SYUHEI NISHI1 AND SATOSHI CHIBA1 Department of Ecology and Evolutionary Biology, Graduate School of Life Sciences, University of Tohoku, Aobayama, Sendai 980-8578, Japan; Present address: Smithsonian Tropical Research Institute, Apartado 0843-03092, Balboa, Ancon, Panama, Republic of Panama (Received 13 December 2006; accepted 14 April 2007) ABSTRACT The intertidal snail Batillaria exhibits remarkable variation in the shell colour within and among popu- lations. Field study was conducted to determine the factors in maintaining observed shell colour poly- morphism. Geographical variations in shell colour polymorphisms in B. attramentaria were significantly correlated with the temperature of the locality of the population. Darker morphs were predominant in colder regions, whereas lighter morphs increase their proportion in warmer regions. A consistent association was also found in B. multiformis that co-existed with B. attramentaria. Strong predatory pressure imposed by digenean trematode parasites was observed in B. attramentaria. However, it is unlikely to affect the colour variations, because no correlation exists between colour morphs and trema- tode parasitism. Although visual selection may also contribute to colour variation in Batillaria, no evidence is found for the existence of visual predators that affect colour patterns of these snails. The deficit of variation in cold regions is possibly due to selection against brighter morphs, because bright colours reflect heat. Although dark shells absorb sunlight and may therefore be exposed to the risks of overheating and drying up in a hot habitat, the darkest morph was frequently observed in the warmer regions, suggesting that physical selection on the colour morphs can be relaxed in the warmer environment.

We compared the digestive enzyme activities for four hard degradable carbohydrates, namely, cellulose, mannan, xylan, and laminarin. Among the investigated four species, Cerithidea rhizophorarum showed the highest cellulase, mannanase, xylanase, and laminarinase activi- ties, and was also dominantly distributed in the estuary reed bed. The results of CN stable isotopic analysis suggested that this species assimilated organic matter derived from reeds. Hard degradable carbohydrates, including plant com- ponents derived from the reed bed or from dry land, accumulate in the sediment of estuaries. Estuarine benthic ani- mals are assumed to consume these accumulated hard degradable carbohydrates, as well as microphytobenthos and particulate organic matter (including phytoplankton).

However, few studies have focused on the river estuaries of small and medium rivers. Molluscan fauna data in large estuaries or in the estuaries of large rivers have been collected by the The National Census on River Environments (conducted by the Ministry of Land, Infrastructure, Transport and Tourism) or National Survey on the Natural Environment (conducted by the Ministry of Environment). On the other hand, molluscan fauna of small and medium rivers are managed by local governments and have rarely been investigated. © Itsukushima R et al.

The analysis indicated that B. multiformis and B. flectosiphonata are closely related to each other and that B. zonalis is the basal of the four species. All snails with a shell that resembled the shell of B. flectosiphonata that were collected from Ariake Bay and the Goto Islands had mitochondrial DNA that corresponded to that of either B. multiformis or B. cumingi. Our results suggest that the morphological characteristics that have been used to discriminate among species in the genus Batillaria need to be revised.

Snails and their possible food sources were collected from the river- sea transects at the mouths of the Iroha and Katsura rivers in northeastern Kyushu, Japan, which differ in land use parameters (e.g., the ratio of agricultural area in the catchment area). There was a shift in the δ13C of the snail along the transects, showing higher values at the upstream stations (−15.8 and −14.8‰) and lower values (−17.5 and −17.1‰) at the seaward stations.
