Two New Species of Amphidromus (Mollusca: Gastropoda: Camaenidae) from Indonesia and Vietnam

Two new species of the land snails in the genus Amphidromus Albers, 1850 from Indonesia, and Vietnam are described: Amphidromus gisellelieae n. sp. from Indonesia, Amphidromus phamvutuanhae n. sp. They are compared to the closest congeners in this genus.

A new subspecies of Cinctura (Gastropoda: Fasciolariidae) from the Ten Thousand Islands, Florida

A new geographical bathymetric subspecies of the offshore deepwater species Cinctura tortugana (Hollister, 1957) is described from shallow subtidal depths off southwestern Florida. The new subspecies, Cinctura tortugana foxi, is described from offshore of the Ten Thousand Islands, in Collier and Monroe Counties, Florida.

Introducing a new genus of Marginellidae from Africa: Africosta new genus (Gastropoda: Marginellidae) along with the description of two new species

A small group Marginellidae species were moved between genera several times by different authors, described as Marginella, sometimes called Glabella, classified under Dentimargo, and also reclassified as being Eratoidea species. This group of very small Marginellidae has their own unique shell characteristics within the family, and are described here within a new genus: Africosta. Four known species are discussed along with the description of two new species from KwaZulu-Natal, South Africa within the new genus.

Studies in Canarium urceus (Linnaeus, 1758) Part 6: A new Canarium species from the Andaman Sea (Gastropoda: Strombidae) and discussion on related species

This part of the Canarium (Canarium) urceus-complex (Linnaeus, 1758) review after Abbott’s revision (Abbott, 1960) revision examines material from the Andaman Sea. At present, material from that region has been synonymised under the name Canarium (Canarium) urceus (Linnaeus, 1758). Canarium (Canarium) andamanense new species is known from the Andamanian Subprovince, a semi enclosed basin that is centered on the Andaman Sea and enclosed by the west coasts of Myanmar and Thailand and the Mergui Archipelago in the east, to the northern Malacca Strait in the south, and to the Andaman and Nicobar Islands in the west. This species is recognized and differentiated by solid, sturdy shells with a triangular body whorl, large knobs on the shoulder and bright orange aperture. This study further confirms that there is a high degree of bioregionalisation within the Canarium complex.

A new endemic species of Chicoreus from Savai’l, Samoa

A new species of Muricidae, Chicoreus (Triplex) tangaroai is described from the Samoan Infraprovince. This new taxa is compared with C. (T.) thomasi (Crosse, 1872) and C. (T.) lorenzi Houart, 2009, related species in the Marquesan Molluscan Province.

Description of two new Conidae subspecies, from Kwazulu-Natal, South Africa

Two new Conidae subspecies, Nataliconus immelmani alanfraseri and Floraconus baeri desuntnotae from the Eastern area of South Africa are described.

New Species of Nannamoria from the Pliocene and Miocene of Australia (Caenogastropoda: Volutidae)

This study provides the taxonomic description of eight species of Nannamoria Iredale, 1929 from Miocene deposits of Victoria and South Australia and Pliocene deposits of Flinders Island Tasmania, Australia. The following new species are described, discussed and compared to their congeners: Nannamoria costatum n. sp., Nannamoria flindersi n. sp., Nannamoria hiscocki n. sp., Nannamoria gnotuki n. sp., Nannamoria alquezae n. sp., Nannamoria cadella n. sp., Nannamoria malonei n. sp. and Nannamoria persimilis n. sp. Various aspects of Nannamoria evolution are discussed.

The Pacific Wing-Oyster, Pteria sterna, off San Diego, California

Pteria sterna is an eastern Pacific pearl oyster of commercial value from Peru to central Baja California, Mexico. The continuous presence of this species in San Diego for a decade is unique as it is approximately 600 km north of the expected range for the species. A minimum of three generations are present in Mission Bay at any point in time and the preferred substrate for attachment are gorgonian corals. The species is also found off shore in cooler water. The continued presence of this oyster raises the question as to the status of this population; is it a permanent range extension or simply a transient population and what has changed that allowed its continued presence?

First Record of Oleacina cyanozoaria (Gundlach in Pfeiffer, 1857) Feeding on a Eleutherodactylus Frog in Pico San Juan, Cumanayagua, Cienfuegos Province, Cuba

Around twenty species of the landsnail subfamily Oleacininae inhabit Cuba. However, only five species were found in south-central region of the island. Despite the frequency of Oleacina in Cuba, these species have been poorly studied and little is known about their ecology, ethology and carnivorous feeding preferences. This field study is the first record showing Oleacina cyanozoaria to be an active predator on a small Eleutherodactylus frog. Small vertebrates have not been previously noted to be part of these voracious species’ diet.
