We critically examine Peruvian taxa belonging to the genera Drymaeus Albers, 1850 and Mesembrinus Albers, 1850, verify their original reference, and figure type materials, if located in and available from museums. We include additional photographs of non-type material when they are deemed useful to show variation. Original figures from the literatu...

p> Resumo : Este trabalho investigou os caenogastrópodes da família Columbellidae Swainson, 1840 pertencentes ao gênero Alia H. Adams & A. Adams, 1853 no litoral do Perú com base no estudo do material tipo depositado no “The Natural History Museum” e material coletado na zona infralitoral da costa do Perú e depositado na coleção malacológica “Carlo...

Critical remarks are made on Drymaeus species, reported from Peru in a study on land snails from National Parks at the eastern side of the Andes. Four of these species (Dry­ maeus multilineatus, D. coniformis, D. glaucostomus, all known from Venezuela or Central America, and D. geomet­ ricus, known from Colombia) appear to be misidentified as Peruv...

The Sechura Desert provides a unique example of a vast palaeo-lagoon system on the Peruvian coast that was active during the first millennium AD. Reconstruction of coastal evolution is made possible by the good resolution of the sedimentary records of the Las Salinas Noroeste coastal plain. Evidence from morphostratigraphy and sedimentary facies in...

Se revisan las especies de la familia Chamidae en el Perú, la cual está constituida por once especies, distribuidas en los géneros Arcinella Schumacker, 1817 y Chama Linnaeus, 1758. Se registra por primera vez a Chama frondosa Broderip, 1835, Chama granti (Strong, 1934), Chama hicksi Valentich-Scott & Coan, 2010, Chama janus Reeve, 1847 y Chama pro...

A faunal overview is presented of the molluscan families Amphibulimidae, Megaspiridae, Odontostomidae, Orthalicidae, Simpulopsidae in Bolivia, Ecuador, and Peru. These Central Andean countries are known for their biodiverse malacofauna, of which the superfamily Orthalicoidea takes relatively a large share. In this paper the five families containing...

The family Orthalicidae is well represented in Peru but, like in other families, some species are well-known and others have not been reported on since their original descriptions. In this paper we present new records for well-known species and elucidate the status of several lesser known taxa. Four taxa are described as new: Bostryx chusgonensis s...

The recent fi nding of a private shell collection from Peru, dating from the early 20th century, sheds some new light on the history of Neotropical malacology. The collection of J.J. Bravo is partly reconstructed and some data is given on his life and conchological activities. It shows that, in the early 20th century, connections did exist between...

Tentacle No. 17—January 2009 6 important – such as squid, common hake, croaker and shrimp – the ecosystem's global significance resides in the fact that it provides a feeding ground for migratory birds, fish, turtles and sea mammals. As for invertebrates, there are 900 species of molluscs alone, some of which are only found in the Patagonian Sea. T...
