NUMBER 2202 DECEMBER I5, I964 Results of the Puritan-American Museum of Natural History Expedition to Western Mexico 20. The Recent Mollusks: Gastropoda: Harpidae, Vasidae, and Volutidae BY WILLIAM K. EMERSON' INTRODUCTION The present paper continues a study of the Recent marine mollusks collected in west Mexican waters during the course of the expedition. Previous reports considered the family Conidae (Emerson and Old, 1962), the superfamily Cypraeacea (Emerson and Old, 1963a), and the super- families Strombacea, Tonnacea, and Cymatiacea (Emerson and Old, 1963b). The present report treats the gastropod families Harpidae, Vasi- dae, and Volutidae. Specimens were taken by shore and intertidal collecting, by skin div- ing, and by dredging from a small skiff and from the schooner "Puritan." Dredging operations were restricted to depths no greater than 50 fathoms. The itinerary and descriptions of the collecting stations were recorded in the general account of the expedition (Emerson, 1958). The present collection contains three of the four eastern Pacific species that represent the families covered by this paper. An attempt is made to 1 Chairman, Department of Living Invertebrates, the American Museum of Natural His- tory. 2 AMERICAN MUSEUM NOVITATES NO. 2202 determine for the west Mexican region the modern and fossil distributions ofthese species.

(Gastropoda: Cerithiopsidae) from Bocas Del Toro, Panama
Caribbean Journal of Science, Vol. 40, No. 2, 192-197, 2004 Copyright 2004 College of Arts and Sciences University of Puerto Rico, Mayagu¨ez Development of Cerithiopsis gemmulosum (Gastropoda: Cerithiopsidae) from Bocas del Toro, Panama RACHEL COLLIN Smithsonian Tropical Research Institute, Unit 0948, APO AA 34002, USA e-mail: [email protected] ABSTRACT.—The relationships between the seven families in the Ptenoglossa and the relationships be- tween the Ptenoglossa and other gastropod groups have been based on anatomical features associated with feeding, and on developmental characters. However the embryonic development of several of these families remains undescribed. Here I describe the development of Cerithiopsis gemmulosum from Bocas del Toro Province, Panama. This species lives on and lays its thin-walled egg capsules in Halichondria melanadocia sponges. The 79 µm eggs have equal cleavage with a polar lobe. The ciliated “trochophore” stage is followed by an encapsulated veliger which has distinct embryonic kidneys and large granular cells that cover the head vesicle. The black eyes are large and develop early, but there is no pigmented mantle organ. At hatching the brown larval shell is a single whorl and 127 µm long, and each semicircular velar lobe is unpigmented. The velar lobes are equal in size at hatching, but as the shell grows and becomes high-spired the right lobe grows to twice the size of the left lobe. The late larval shell is smooth but has a prominent beak flanked by two distinct notches that fit the velar lobes. After 3 weeks in culture the velum begins to shrink, and larvae with 500 µm shell length metamorphose when exposed to host sponge. -

Habitat-Forming Deep-Sea Corals in the Northeast Pacific Ocean
Habitat-forming deep-sea corals in the Northeast Pacific Ocean Peter Etnoyer1, Lance E. Morgan2 1 Aquanautix Consulting, 3777 Griffith View Drive, Los Angeles, CA 90039, USA ([email protected]) 2 Marine Conservation Biology Institute, 4878 Warm Springs Rd., Glen Ellen, CA 95442, USA Abstract. We define habitat-forming deep-sea corals as those families of octocorals, hexacorals, and stylasterids with species that live deeper than 200 m, with a majority of species exhibiting complex branching morphology and a sufficient size to provide substrata or refugia to associated species. We present 2,649 records (name, geoposition, depth, and data quality) from eleven institutions on eight habitat- forming deep-sea coral families, including octocorals in the families Coralliidae, Isididae, Paragorgiidae and Primnoidae, hexacorals in the families Antipathidae, Oculinidae and Caryophylliidae, and stylasterids in the family Stylasteridae. The data are ranked according to record quality. We compare family range and distribution as predicted by historical records to the family extent as informed by recent collections aboard the National Oceanic of Atmospheric Administration (NOAA) Office of Ocean Exploration 2002 Gulf of Alaska Seamount Expedition (GOASEX). We present a map of one of these families, the Primnoidae. We find that these habitat-forming families are widespread throughout the Northeast Pacific, save Caryophylliidae (Lophelia sp.) and Oculinidae (Madrepora sp.), which are limited in occurrence. Most coral records fall on the continental shelves, in Alaska, or Hawaii, likely reflecting research effort. The vertical range of these families, based on large samples (N >200), is impressive. Four families have maximum-recorded depths deeper than 1500 m, and minimum depths shallower than 40 m. -

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. -

Linarite occurs with copper and lead minerals (azurite, malachite, cerussite, brochantite, Although many species have no shell, or reduced anglesite, smithsonite, and others), and may be shell, in general gastropods are characterized by a confused for azurite. However, linarite will not fizz coiled, unchambered shell. Often there is an in hydrochloric acid, as it is not a carbonate (which operculum (trap door) attached to their foot, that azurite is). -
Influence of Frederick (Ted) M. Bayer on Deep-Water Octocoral Research
Vol. 397: 7–10, 2009 MARINE ECOLOGY PROGRESS SERIES Published December 17 doi: 10.3354/meps08066 Mar Ecol Prog Ser Contribution to the Theme Section ‘Conservation and management of deep-sea corals and coral reefs’ OPENPEN ACCESSCCESS Influence of Frederick (Ted) M. Bayer on deep-water octocoral research Stephen D. Cairns* Department of Invertebrate Zoology, Smithsonian Institution, PO Box 37012, Washington, DC 20560, USA ABSTRACT: The impact of Ted Bayer’s research on octocorals was extraordinary and his studies will long be used by any student of the group Octocorallia. He leaves behind a legacy of 107 published papers on octocorals, in which he newly described 4 families, 1 subfamily, 48 genera, 2 subgenera, 186 species, and 10 subspecies. An annotated list of his new taxa and all of his manuscripts (including 9 unpublished) are given in an electronic supplement. Although he published on most octocoral families, his favorite groups were the deep-water calcaxonian families from the western Atlantic, central Pacific, and Antarctic; he was also an expert on the precious coral family Coralliidae. He facilitated the study of the subclass by publishing classifications of the higher taxa, an illustrated trilingual glossary of morpho- logical terms, a key to all genera (exclusive of the Pennatulacea), and an annotated bibliography of the literature of the group. He was the first to use scanning electron microscope (SEM) images of sclerites to describe species, and perfected that technique in the use of SEM stereo pairs. He also made a sig- nificant contribution to advances in the knowledge of octocoral axial microstructure, proving that all gorgoniids have a diagnostic type of axial mineralogy.
