Omphalorissa Purchasi
''Omphalorissa purchasi'' is a species of small land snail, a terrestrial gastropod mollusc in the family Hydrocenidae. The type specimen is stored in the Imperial Natural History Museum, Vienna. Description The shell is minute, globosely conical, translucid, imperforate (no umbilicus. The sculpture consists of very fine growth-striae only. The colour is horny-fuscous. The epidermis is thin and shiny. The spire is conical, and rather obtuse. The protoconch is minute, strongly convex, smooth. The shell has 4-5 convex whorls. The last whorl is slightly greater than one-third of the height of the shell. The base is convex. The suture is impressed. The aperture is a little oblique, subcircular. The peristome is simple, straight. The columella is slightly concave, white. The inner lip is spread over the umbilicus, sealing it up more or less completely.

Umbilicus (mollusc)
The umbilicus of a shell is the axially aligned, hollow cone-shaped space within the whorls of a coiled mollusc shell. The term umbilicus is often used in descriptions of gastropod shells, i.e. it is a feature present on the ventral (or under) side of many (but not all) snail shells, including some species of sea snails, land snails, and freshwater snails. The word is also applied to the depressed central area on the planispiral coiled shells of ''Nautilus'' species and fossil ammonites. (These are not gastropods, but shelled cephalopods.) In gastropods The spirally coiled whorls of gastropod shells frequently connect to each other by their inner sides, during the natural course of its formation. This results in a more or less solid central axial pillar, known as the columella. The more intimate the contact between the concave side of the whorls is, the more solid the columella becomes. On the other hand, if this connection is less intense, a hollow space inside the whorls may re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferdinand Von Hochstetter
Christian Gottlieb Ferdinand Ritter von Hochstetter (30 April 1829 – 18 July 1884) was a German-Austrian geologist. Career Having received his early education at the evangelical seminary at Maulbronn, Ferdinand proceeded to the University of Tübingen and the Tübinger Stift; there, under Friedrich August von Quenstedt, the interest he already felt in geology became permanently fixed, and he obtained his doctor's degree and a travelling scholarship. In 1852 he joined the staff of the Imperial Geological Survey of Austria and was engaged until 1856 in parts of Bohemia, especially in the Bohemian Forest, and in the Fichtel Hills and Karlsbad mountains. His excellent reports established his reputation. Thus he came to be chosen as geologist to the Novara expedition (1857–59), and made numerous valuable observations in the voyage round the world. The Novara arrived in New Zealand on 22 December 1858. Almost immediately he met the German scientist Julius von Haast who had al ...

Arthur Guyon Purchas
Arthur Guyon Purchas (27 September 1821 – 28 May 1906) was a clergyman, missionary, surgeon, musician, engineer, inventor, pioneer, geologist and botanist born in the Wye Valley, Wales, who lived most of his life in Auckland, New Zealand. He was the father of fourteen children and an important figure during British colonisation of New Zealand, described as an 'amazingly versatile colonist'. Early life Purchas was born in Wye Valley, Monmouthshire, Wales on 27 September 1821. In 1836, he was apprenticed to a doctor. He began studying at Guy's Hospital in London, England in 1839 under doctors Addison and Bright, gaining his Membership of the Royal Colleges of Surgeons of Great Britain and Ireland, M.R.C.S. and L.S.A. after three years on 29 September 1842. He was subsequently appointed resident surgeon at Royal Southern Hospital, Southern and Toxteth Hospital in Liverpool.

Bay Of Islands
The Bay of Islands is an area on the east coast of the Far North District of the North Island of New Zealand. It is one of the most popular fishing, sailing and tourist destinations in the country, and has been renowned internationally for its big-game fishing since American author Zane Grey publicised it in the 1930s. It is north-west of the city of Whangarei. Cape Reinga, at the northern tip of the country, is about by road further to the north-west. Geography The bay itself is an irregularly-shaped -wide, drowned valley system and a natural harbour. It contains 144 islands, of which the largest is Urupukapuka, and numerous peninsulas and inlets. The three largest inlets are Waikare Inlet in the south, and Kerikeri and Te Puna (Mangonui) inlets in the north-west. The Purerua Peninsula, north of Te Puna Inlet, separates the north-western part of the bay from the Pacific Ocean, and Cape Brett Peninsula extends into the ocean at the eastern end of the bay. The biggest t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Umbilicus (mollusc)
The umbilicus of a shell is the axially aligned, hollow cone-shaped space within the whorls of a coiled mollusc shell. The term umbilicus is often used in descriptions of gastropod shells, i.e. it is a feature present on the ventral (or under) side of many (but not all) snail shells, including some species of sea snails, land snails, and freshwater snails. The word is also applied to the depressed central area on the planispiral coiled shells of ''Nautilus'' species and fossil ammonites. (These are not gastropods, but shelled cephalopods.) In gastropods The spirally coiled whorls of gastropod shells frequently connect to each other by their inner sides, during the natural course of its formation. This results in a more or less solid central axial pillar, known as the columella. The more intimate the contact between the concave side of the whorls is, the more solid the columella becomes.

Columella (gastropod)
The columella (meaning "little column") or (in older texts) pillar is a central anatomical feature of a coiled snail shell, a gastropod shell. The columella is often only clearly visible as a structure when the shell is broken, sliced in half vertically, or viewed as an X-ray image. The columella runs from the apex of the shell to the midpoint of the undersurface of the shell, or the tip of the siphonal canal in those shells which have a siphonal canal. If a snail shell is visualized as a cone of shelly material which is wrapped around a central axis, then the columella more or less coincides spatially with the central axis of the shell. In the case of shells that have an umbilicus, the columella is a hollow structure. The columella of some groups of gastropod shells can have a number of plications or folds (the columellar fold, plaits or plicae), which are usually visible when looking to the inner lip into the aperture of the shell. These folds can be wide or narrow, prominent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aperture (mollusc)
The aperture is an opening in certain kinds of mollusc shells: it is the main opening of the shell, where the head-foot part of the body of the animal emerges for locomotion, feeding, etc. The term ''aperture'' is used for the main opening in gastropod shells, scaphopod shells, and also for ''Nautilus'' and ammonite shells. The word is not used to describe bivalve shells, where a natural opening between the two shell valves in the closed position is usually called a ''gape''. Scaphopod shells are tubular, and thus they have two openings: a main anterior aperture and a smaller posterior aperture. As well as the aperture, some gastropod shells have additional openings in their shells for respiration; this is the case in some Fissurellidae (keyhole limpets) where the central smaller opening at the apex of the shell is called an orifice, and in the Haliotidae (abalones) where the row of respiratory openings in the shell are also called orifices.

Suture (gastropod)
In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements. Sutures are found in the skeletons or exoskeletons of a wide range of animals, in both invertebrates and vertebrates. Sutures are found in animals with hard parts from the Cambrian period to the present day. Sutures were and are formed by several different methods, and they exist between hard parts that are made from several different materials. Vertebrate skeletons The skeletons of vertebrate animals (fish, amphibians, reptiles, birds, and mammals) are made of bone, in which the main rigid ingredient is calcium phosphate. Cranial sutures The skulls of most vertebrates consist of sets of bony plates held together by cranial sutures. These sutures are held together mainly by Sharpey's fibers which grow from each bone into the adjoining one. Sutures in the ankles of land vertebrates In the type of crurotarsal ankle which is found i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whorl (mollusc)
A whorl is a single, complete 360° revolution or turn in the spiral growth of a mollusc shell. A spiral configuration of the shell is found in numerous gastropods, but it is also found in shelled cephalopods including ''Nautilus'', ''Spirula'' and the large extinct subclass of cephalopods known as the ammonites. A spiral shell can be visualized as consisting of a long conical tube, the growth of which is coiled into an overall helical or planispiral shape, for reasons of both strength and compactness. The number of whorls which exist in an adult shell of a particular species depends on mathematical factors in the geometric growth, as described in D'Arcy Wentworth Thompson's classic 1917 book ''On Growth and Form'', and by David Raup. The main factor is how rapidly the conical tube expands (or flares-out) over time. When the rate of expansion is low, such that each subsequent whorl is not that much wider than the previous one, then the adult shell has numerous whorls. When the ...
