COCCULINIFORM LIMPETS (COCCULINIDAE AND PYROPELTIDAE) LIVING ON WHALE BONE IN THE DEEP SEA OFF CALIFORNIA

Cocculiniform limpets of the families Cocculinidae and Pyropeltidaeare here reported for the first time on whale bone in the deepsea. The new species and records of previously described speciesare from four whale-falls at bathyal depths on the continentalmargin off California, from Monterey Bay to the Catalina Basin.The family Cocculinidae is represented by the new species Cocculinacraigsmithi. With few exceptions, the previously known speciesof Cocculinidae are known from wood substrates. The family Pyropeltidaeis represented by three species: Pyropelta musaica McLean &Haszprunar, 1987, originally described from the Juan de Fucahydrothermal vents, Pyropelta corymba McLean & Haszprunar,1987, originally described from the hydrothermal vent habitatat the Guaymas Basin, and one new species, P. wakefieldi. Thetwo previously known species of Pyropelta have heretofore beenregarded as obligate members of the sulfide habitat of hydrothermalvents. Pyropelta species are the first gastropods known fromboth habitats. Like the hydrothermal-vent habitat, the newlyreported habitat on whale bone is also a sulfide-rich, reducingenvironment.

Revision of the genus Stentor Oken (Protozoa, Ciliophora) and description of S.araucanus nov. spec, from South American lakes

Stentor is a heterolrich ciliate which often forms lawn-likecovers on the bottom and/or blooms in the pelagial of lakesworldwide. The species involved in these spectacular eventswere usually either not determined or misidentified becausethe keys are outdated and incomplete. Thus, we have revisedthe nominal species described since the first major revisionby Ehrenberg (1838). Main species characteristics are the presence/absenceof symbiotic algae, the shape of the macronucleus and the colourof the cortical pigment granules. The last character mentionedmust be studied in live cells because the pigment bleaches inchemically fixed specimens. Nineteen valid species are recognizedand dichotomously keyed according to these characteristics.Twenty-seven other species and varieties, described after Ehrenberg'srevision, are synonyms or species indeterminata A new species.S.araucanus, is described from South American lakes. It is asmall, broadly trumpet-shaped Stentor with symbiotic algae,vermiform macronucleus and blue-green cortical granules. Stentoraraucanus is probably euplanktic and restricted to the southernhemisphere. Stentor auriculalus Kahl. 1932 sensu Wang (1934)is recognized as a new species, Condylostoma wangi, and transferredto the genus Condylostoma. New nomenclatural corrections: Stentorbaicalius nom. nov. (pro S.pygmaeus, preoccupied). S loricatiisnom. corr. (for S.loricata), S.ruber nom. corr. (for S.ruhra).

A new species of pelagic amphipod of the genus Lestrigonus (Crustacea: Amphipoda: Hyperiidea: Hyperiidae) from eastern Australia

A new species of pelagic amphipod, Lestrigonus ducrayi sp. nov.,from eastern Australia, is described and illustrated. It isvery similar to Lestrigonus bengalensis Giles, 1887, but isreadily distinguished by a relatively shorter telson (aboutone-third peduncle uropod 3) and, in mature males, pereonites1–5 are fused as in females. The two species often occurtogether in the same plankton sample; the new species beingmore abundant inshore, although both species seem to preferinshore waters. A key to the species of Lestrigonus is provided.     

Revision of the Genus Goodallia (Bivalvia: Astartidae) with the Description of Two New Species

A revision of the Recent species of the genus Goodallia (Astartidae)is presented. Adult shell and prodissoconch morphology of allthe species are described and figured. In total, five speciesare recognized: G. triangularis (Montagu, 1803), G. pusilla(Forbes, 1844), G. macandrewi (Smith, 1881), G. micalii new species,and G. gofasi new species. G. triangularis and G. pusilla are widespreaddistributed in the Atlantic coasts of Europe and North Africa,and in the Mediterranean. G. macandrewi is restricted to thetype locality in the Canary Islands, while what has been calledG. macandrewi from the Mediterranean corresponds to an undescribedspecies here named G. micalii, distributed in the Central andEastern Mediterranean. A second undescribed species from offthe Atlantic Moroccan coast is named G. gofasi, and is knownonly from the type material of station B33 of the expedition CINECA CHARCOT III. The named forms, variability and distributionof G. triangularis are discussed. (Received 30 January 1998; accepted 27 August 1998)     

BROODING AND NON-BROODING DACRYDIUM (BIVALVIA: MYTILIDAE): A REVIEW OF THE ATLANTIC SPECIES

The Atlantic species of the marine bivalve genus Dacrydium arereviewed, with particular emphasis on their hinge and protoconchcharacters. The basic groundplan of a Dacrydium comprises afunctional primary ligament, a paired series of primary teeth,and a posterior row of secondary teeth separated from the latterby a secondary ligament; this can be transformed into a singleseries either by loss of the secondary ligament and mergingprimary and secondary teeth, or by loss of secondary teeth andligament through paedomorphosis. Twelve species are recognized, of which eleven are illustrated.One abyssal species is not separable morphologically from theIndian Ocean D. speculum Poutiers, 1989 and is new to the Atlantic;four new species (D. wareni, D. dauvini, D. filiferum and D.balgimi) are described; a Caribbean form which is hardly distinctfrom the Eastern Pacific D. elegantu-lum Soot-Ryen, 1955, isdescribed as a new subspecies D. e. hendersoni. The larvae are brooded in D. hyalinum (Mon-terosato, 1875),D. viviparum Ockelmann, 1983 and D. balgimi. The brooding specieshave larger larvae (protoconch 210 to 315 µm long) thanthe non-brooding (protoconch 120 to 150 µm long), andreach a smaller adult size (1.4 to 3 mm instead of 4.5–5mm). A phylogenetic reconstruction is attempted using parsimonyanalysis of hinge and shell characters as well as the brooding/nonbrooding character.

DESCRIPTION OF A NEW SPECIES OF PHYLLIDIOPSIS BERGH (NUDIBRANCHIA: DORIDOIDEA: PHYLLIDIIDAE) FROM THE TROPICAL WESTERN PACIFIC, WITH COMMENTS ON THE ATLANTIC SPECIES

A new species of phyllidiid nudibranch, Phyllidiopsis shireenae,is described. The new species has a middorsal crest insteadof being flattened dorso-ventrally like most phyllidiids. Itsbody is a very pale shade of pink with black bands, and itsrhinophores are salmon pink. The anatomy of the alimentary systemand reproductive system are described. Characters originallyused by Bergh (1875) to differentiate the genus are supportedby this new species. Phyllidiopsis shi-reenae is presently knownfrom coral reef habitats in the extreme western Pacific Ocean.A review of the taxonomic status of the Atlantic specis of Phyllidiopsisis required. ^*Present address: Australian Biological and Environmental Survey.Australian National Parks and Wildlife Service, GPO Box 1383,Canberra.
