The family Omalogyridae comprises some of the smallest known marine snails. [] Key Result The new species, Ammonicera mcleani, A. mexicana and A. sleursi, are the first omalogyrid species described from the Eastern Pacific coast of North America. Redescriptions of the Australian omalogyrids Ammonicera sucina (Laseron, 1954) and Omalogyra liliputia (Laseron, 1954) are also presented, detailing for the first time ultrastructural aspects of their shell morphology.

A new species of the genus Ammonicera (Prosobranchia, Omalogyridae) in a coralline algae community from Jeju Island, off the south coast of Korea
This new species can be clearly distinguished from other Ammonicera species from the Pacific Ocean by the presence of a spiral cord and about 25 slightly-elevated axial ribs, resulting in about 25 nodules at intersecting points of the cord and ribs on the last whorl of the teleoconch.
Insights from enigmatic clades - comparative microanatomy and evolution of the Heterobranchia (Mollusca, Gastropoda)
An integrative taxonomic workfl ow for delimiting potentially cryptic and elusive mesopsammic species, that also may be of use for other rare(ly) sampled invertebrates is presented.
Smaller molluscs from a multi-taxon survey (2012–2014) of the shallow marine environments of the tropical Kimberley region, Western Australia
ABSTRACT – The marine environments of Western Australia’s Kimberley region (coast to continental edge) are rich in spatial diversity and vast in scale affording a broad range of habitats for marine

New and little known mollusca from Iceland and Scandinavia
A new family name, Pendromidae (based on the genus Pendroma DALL, 1927), is introduced to replace Trachysmatidae, which was based on an erroneously identified genus.
Morphological, ecological and molecular characterization of the enigmatic planispiral snail genus Adeuomphalus (Vetigastropoda: Seguenzioidea)
Examining newly collected and museum-stored specimens from upper to lower bathyal depths in the Atlantic, Mediterranean, Pacific and Indian Oceans and recognizing seven recent species revealed six monophyletic groups in Seguenzioidea: Seguenziidae, Chilodontidae, Calliotropidae, Cataegidae, Spinicalliotropis and skenei- morph seguenzIOids.
New records of Caribbean Gastropods (Skeneidae, Tornidae, Orbitestellidae and Omalogyridae) for Saint Peter and Saint Paul Archipelago (Brazil)
It is believed that the taxa studied have a circum-Caribbean distribution and are dispersed from the Caribbean and northeastern portion of South America to the SPSPA under the influence of the equatorial subcurrent, occupying seamounts and/or oceanic banks in a gradient fashion.
Micromolluscs in Japan: taxonomic composition, habitats, and future topics
In this review, a summary of the current state of knowledge is given for all known micromolluscan families distributed in Japan.
The littoral molluscs (Gastropoda, Bivalvia and Polyplacophora) of Sao Vicente, Capelas (Sao Miguel Island, Azores): Ecology and biological associations to algae
A two-year systematic survey was conducted in a rocky exposed shore located at Porto das Baleias in the north coast of São Miguel Island and suppos-edly representative of the Azorean rocky shores, where zonation of the littoral molluscs was established for the most abundant species and possible mollUScs/algae biological associations were studied.
Liotidae and allied molluscs from the Dampierian Zoogeographical Province
This paper is based on two collections from Darwiu, Northeru Territory, which, as far as is known, are the only collections of small shells available from within the Dampierian Zoogeographical
Skeneidae, Vitrinellidae and Orbitestellidae (Mollusca: Gastropoda) associated with biogenic substrata from bathyal depths off New Zealand and New South Wales
Skeneids, orbitestellids and a vitrinellid are recorded for the first time as characteristic components of the fauna of submerged wood as well as new taxa from New Zealand.
The molluscs of the intertidal algal turf in the Azores Los moluscos del cesped algal intermareale en Azores
The molluscan fauna of the high intertidal algal turf on the island of Pico (Azores) was studied in order to complement existing descriptions of the intertidal biota on these islands. A total of
Biodiversity of Zoobenthos in the Coastal Zone of the South Coast of Crimea (Laspi Bay Area)
Based on data of a1996 benthos survey, the structure of soft bottom zoobenthos of Laspi Bay (South Coast of Crimea, the Black Sea) was examined. One hundred thirty-one species of macrozoobenthos,
Shells of Mollusca Collected from the Seas of Turkey
A large number of molluscan shells were collected from the seas of Turkey and examined to determine their species and to point out the species found in each sea to reveal a total of 610 shell species and many varieties belonging to various classes, subclasses, families and subfamilies of mollsusca.
