While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. -

Later, the detailed examination of this animal revealed that it represented clearly a new species of the genus Cyerce Bergh, 1871 (=Lobiancoia Trinchese, 1881) of the family Caliphyllidae. As only a single species of this genus, C. nigricans (Pease, 1866), has been known so far in Japan from Ishigaki Island of the Ryukyu Archipelago by Baba (1936), this finding seems noteworthy. This new species is here named after the author's teacher, Dr. Kikutaro Baba, as it was dedicated to him in cele bration ofhis 70th birthday, July 11 of 1975.

ATKINS Abstracts Soil CaCO. levels were determined for six ecosystems in Washtenaw and Wayne Counties, Michigan and in Linn County, Iowa; and correlation between these results and the shell thickness of certain terrestrial snails was made. Species used were Anguispira alternata ( Say), Triodopsis multilineata (Say), and T. albolabris (Say). Two ecosystems had high caco. levels ( 120-144 ppm), three had intermedi ate levels ( 93-99ppm) and one had a low level ( 40 ppm). 'Width/thickness ratios of live and cast shells showed that those in high calcium ecosystems had thicker shells than those in low calcium ecosystems, though there were large de viations in the thickness values. -
86 Animal Miraculum Discovery of Living Anguispira Alternata (Say
Discovery of Living Anguispira alternata (Say, 1816) (Discidae: Gastropoda) in Louisiana, USA Russell L. Minton*, Erin L. Basiger, and Casey B. Nolan Department of Biology, University of Louisiana at Monroe, 700 University Avenue, Monroe, LA 71209-0520, USA (Accepted January 29, 2010) Of the 13 recognized species of Anguispira in the US, 2 are listed as occurring in Louisiana (NatureServe 2009). (A) Anguispira alternata (Say, 1819) is a pulmonate land snail found throughout the eastern US, including states bordering the Mississippi River to the west (Hubricht 1985). The other species, A. strongylodes (Pfeiffer, 1854), is found across the southern US, with a range that narrowly overlaps A. alternata at its northern boundary. The shell of A. strongylodes differs from that of A. alternata by lacking streaks along the base and the umbilicus and by having smaller spots along the shell periphery (Pilsbry 1948). Hubricht (1985) listed only fossil A. alternata as occurring in Louisiana and Mississippi, while NatureServe (2009) lists it as extirpated in both states. Pilsbry viewed strongylodes as a weakly differentiated subspecies of A. alternata endemic to east-central Texas, although Hubricht (1960) later elevated strongylodes to species status and established its currently recognized range (Hubricht 1985). During a recent survey of Black Bayou Lake National Wildlife Refuge (32.6°N, 92.04°W) in Monroe, LA, we collected (B) a number of living and dead specimens that matched the original description and other published images of A. alternata and not A. strongylodes. These specimens possessed the color patterns described by Pilsbry (1948), most notably prominent spots on the periphery and streaks on the underside that separate A. -

Centenario km 5.5, Chetumal, Quintana Roo, México ∗ Corresponding author: [email protected] 2 Received: 25/07/2014 Accepted: 20/11/2014 ABSTRACT Population dynamics of the native apple snail Pomacea flagellata (Ampullariidae) in a coastal lagoon of the Mexican Caribbean Apple snails Pomacea spp inhabit tropical and subtropical freshwater environments and are of ecological and economic importance. To evaluate the population dynamics of P. flagellata, monthly samples were collected from Guerrero Lagoon (Yucatán Peninsula) from June 2012 to May 2013. The measured environmental variables did not differ significantly among the sampling stations. However, salinity was lower during the rainy season, and the temperature was lower during the north season (i.e., the season dominated by cold fronts). The snails were more abundant during the rainy season, and they were restricted to the portion of the lagoon that receives freshwater discharges. The snails ranged from 4 to 55 mm in size, with a –1 maximum estimated length of L∞ = 57.75 mm and a growth rate of K = 0.68 y (the abbreviation “y” means “year”) with a seasonal oscillation; the lowest growth rate occurred in early December. -

By .T OYCE ALLAN. The Australian Museum. Sydney. (Plates xli-xliii and ~Iap.) Intr'oduction. In June, 1941, the Clarence River Heads, north coast of New South Wales, were visited for the purpose of collecting certain marine molluscan material, in particular, Nudibranchia. For some time Mr. A. A. Cameron, of Harwood Island, Clarence River, had forwarded to the Museum marine specimens from this locality, a considerable proportion of which had indicated the presence there of a strong, extra-Australian ·tropical influence of ecological and zoo-geographical importance. The nudibranch material was particularly interesting in this respect, since the majority of the rare species he had forwarded were collected in a restricted area, the Angourie Pool, a z ~ oU ANGOURIE PT 434 RECORDS OF T.RE AUSTRALIAN MUSEUM. small excavation in the rocky shore shelf at Angourie, a popular fishing spot. The trip was therefore undertaken to investigate the molluscan fauna in that locality, with special attention to the preparation of field notes and colour sketches of the Nudibranchia encountered. A considerable variety of both tropical and temperate rocky shore shells was present in all areas visited-in one locality alone, Shelly Beach, no less than eleven species of cowries were noticed in an hour or so. -

After macroscopic observation of snails, the hepatopancreas, digestive tract, sex organs, slime and haemolymph were isolated. These samples were examined using the flotation techniques and direct rubbing. Of the 360 snails sampled, 213 (59.3%) were infested, that is 147 (82.1%) for A. marginata and 66 (36.7%) for A. fulica respectively. The highest infestation rate was recorded on protozoans (41.4%) followed by nematode (24.7%). The most represented parasites were Trichodina achatinae (23.9%) and Strongyloides stercoralis (16.1%); while the least represented were cyst of Balantidium coli (8.1%), Enteromonas sp.

1 Mobilising molluscan models and genomes in biology 2 Angus Davison1 and Maurine Neiman2 3 1. School of Life Sciences, University Park, University of Nottingham, NG7 2RD, UK 4 2. Department of Biology, University of Iowa, Iowa City, IA, USA and Department of Gender, 5 Women's, and Sexuality Studies, University of Iowa, Iowa, City, IA, USA 6 Abstract 7 Molluscs are amongst the most ancient, diverse, and important of all animal taxa. Even so, 8 no individual mollusc species has emerged as a broadly applied model system in biology. 9 We here make the case that both perceptual and methodological barriers have played a role 10 in the relative neglect of molluscs as research organisms. We then summarize the current 11 application and potential of molluscs and their genomes to address important questions in 12 animal biology, and the state of the field when it comes to the availability of resources such 13 as genome assemblies, cell lines, and other key elements necessary to mobilising the 14 development of molluscan model systems. We conclude by contending that a cohesive 15 research community that works together to elevate multiple molluscan systems to ‘model’ 16 status will create new opportunities in addressing basic and applied biological problems, 17 including general features of animal evolution. 18 Introduction 19 Molluscs are globally important as sources of food, calcium and pearls, and as vectors of 20 human disease. From an evolutionary perspective, molluscs are notable for their remarkable 21 diversity: originating over 500 million years ago, there are over 70,000 extant mollusc 22 species [1], with molluscs present in virtually every ecosystem. -
