Phasianella Bryani
''Phasianella'', common name the pheasant shells, is a genus of small sea snails with a calcareous operculum and a colorfully patterned shell, a marine gastropod mollusc in the family Phasianellidae. Description The white shell has a bulimiform or subglobose shape. It is polished, without epidermis or nacre, variegated with bright colors. The heavy operculum is calcareous, internally paucispiral, with a nucleus near the basal margin. It is externally convex. The columella is smooth, arcuate and not dentate. The animal has long tentacles, and has usually pectinated head lobes. These frontal lobes distinguish this genus from ''Tricolia'', which lacks frontal lobes. The epipodial line contains generally cirrhi. The branchial plume is long. The narrow foot is long, pointed posteriorly, rounded before. Below it is divided longitudinally by a median groove. The rhomboidal jaws are covered with imbricating scales. The radula is rather short. The formula of teeth is typically ∞ 5. ...

Indo-West Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in a ...

Archiv Für Molluskenkunde
''Archiv für Molluskenkunde'' is a peer-reviewed scientific journal published by the Senckenberg Nature Research Society, covering research in malacology. Coverage ''Archiv für Molluskenkunde'' publishes original research on all aspects of molluscan biodiversity, mostly on systematics, taxonomy, phylogeny and morphology, also accepting research on the ecology and biogeography of all groups of molluscs, both living and fossil (Cenozoic only). Articles are published in English. History ''Archiv für Molluskenkunde'' derives from the ''Nachrichtsblatt der Deutschen Malakozoologischen Gesellschaft'' 'Newsletter of the German Malacological Society'' first published in 1868. Hence it is the oldest malacological journal still publishing. The name changed in 1921, but the numbering of volumes runs continuously between the titles. The parent society transferred ownership of the journal to the Senckenberg Nature Research Society in 1936 in order to avoid government (Nazi) interference. ...
