Gibberula
''Gibberula'' is a genus of minute sea snail, a marine gastropod mollusk or micromollusk in the family Cystiscidae, previously placed in the family Marginellidae, the margin shells or marginellids. (Note: Gastropod taxonomy has been in flux for many years. This is especially true currently, because of new research in molecular phylogeny. Because of all this ongoing change, different reliable sources can yield very different classifications, especially within certain poorly understood groups.) Other genus-group names are available for small shells resembling ''Gibberula''. These include ''Granula'' Jousseaume, 1875 and ''Kogomea'' Habe, 1951. They are distinguished from ''Gibberula'' only on the basis of smaller size and other rather tenuous conchological differentiations. Shell description The shell of this genus is 1.5 to 10 mm in length, ovoid, stout, with a small, low spire. The outer lip is thickened but without an external varix. It is usually denticulated inside. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Persicula
''Persicula'' is a taxonomic genus of minute to small predatory sea snails, marine gastropod mollusks. It includes several species which are micromollusks.Persicula Schumacher, 1817.

Cystiscidae
Cystiscidae is a taxonomic family of minute sea snails, marine gastropod mollusks or micromollusks. Description The shell is minute to large, either white, uniformly colored, or patterned; the surface is smooth, sculptured, or axially costate; the spire is flat to immersed, or low to tall; the protoconch is paucispiral; the lip is thickened, smooth or denticulate; an external varix is present or absent; a siphonal notch is present or absent; a posterior notch is present or absent; the columella is multiplicate, internal whorls cystiscid or modified cystiscid type. Mantle cavity with monopectinate ctenidium and bipectinate osphradium. Proboscis pleurembolic; jaws absent; typical radular sac present.

Arnould Locard
Étienne Alexandre Arnould Locard (8 December 1841 – 28 October 1904), usually known as Arnould Locard, was a French naturalist, malacologist and geologist. His name can be abbreviated/spelled as Arnoul at plates, for example Crosse (1980). Crosse H. (1890). "Faune malacologique terrestre et fluvitile de l'Ille de la Trinité (Antilles)." ''Journal de conchyliologie'' 3835335. plate19. Biography Born in Lyon, he was the son of engineer Eugene Locard. He was a student at École Centrale Paris. He is considered one of the more prolific malacologists of the so-called "new school" with Jules René Bourguignat (1828–1892) as his master. Locard is credited with describing hundreds of zoological species, in particular freshwater mussels and gastropods from the genus ''Helix''. During his career he did very little collecting of specimens himself, preferring to work in an institution/museum environment. In 1895, he revised the conchological collection of Jacques Philippe Raymond Dra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siphonal Canal
The siphonal canal is an anatomical feature of the shells of certain groups of sea snails within the clade Neogastropoda. Some sea marine gastropods have a soft tubular anterior extension of the mantle called a siphon through which water is drawn into the mantle cavity and over the gill and which serves as a chemoreceptor to locate food. Siphonal canals allow for active transport of water to sensory organs inside the shell. Organisms without siphonal canals in their shells rely on passive or diffuse transport or water into their shell. Those with siphonal canals have a direct inhalant stream of water that interacts with sensory organs to detect concentration and direction of a stimulus, such as food or mates. In certain groups of carnivorous snails, where the siphon is particularly long, the structure of the shell has been modified in order to house and protect the soft structure of the siphon. Thus the siphonal canal is a semi-tubular extension of the aperture of the shell th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Francis Laseron
Charles Francis Laseron (6 December 1887 – 27 June 1959) was an American-born Australian naturalist and malacologist. Early life and education Laseron was born on 6 December 1887 at Manitowoc, Wisconsin, United States of America, to English parents the Reverend David Laseron, and his wife Frances, née Bradley. After relocating temporarily to London in 1888, the family migrated to Australia in January 1891. In 1892 his father was accidentally shot, causing lasting health problems for Rev. Laseron who resigned his post in Sydney three years later and then moved his family to Lithgow, New South Wales where he was given charge of the parish. Charles attended St Andrew's Cathedral School as scholar and chorister and later studied at Sydney Technical College where he was awarded the diploma in geology. He was employed by the Technological Museum in July 1906 and published a series of papers. Australian Antarctic Expedition He was a member of the Australasian Antarctic Expedition un ...
