Hoplocephalus Bungaroides
The broad-headed snake (''Hoplocephalus bungaroides'') is a species of venomous snake in the family Elapidae. The species is restricted to the Sydney Basin in New South Wales, Australia. It is one of three snakes in the genus '' Hoplocephalus'', all restricted to eastern Australia.

Elapidae
Elapidae (, commonly known as elapids ; grc, ἔλλοψ ''éllops'' "sea-fish") is a family of snakes characterized by their permanently erect fangs at the front of the mouth. Most elapids are venomous, with the exception of the genus Emydocephalus. Many members of this family exhibit a threat display of rearing upwards while spreading out a neck flap. Elapids are endemic to tropical and subtropical regions around the world, with terrestrial forms in Asia, Australia, Africa, and the Americas and marine forms in the Pacific and Indian Oceans. Members of the family have a wide range of sizes, from the white-lipped snake to the king cobra. Most species have neurotoxic venom which is channeled by their hollow fangs, and some may contain other toxic components in various proportions. The family includes 55 genera with some 360 species and over 170 subspecies. Description Terrestrial elapids look similar to the Colubridae; almost all have long, slender bodies with smooth scales, a ...

William Stephens (academic)
William John Stephens , FGS, (16 July 1829 – 22 November 1890) was headmaster at Sydney Grammar School, a professor at the University of Sydney and museum administrator. Stephens was born in Levens, Westmorland, the son of the Rev. William Stephens, of Heversham, Westmorland, and his wife Alicia, ''née'' Daniell. William, junior, was an elder brother of Thomas Stephens. William was educated at Marlborough College, and at The Queen's College, Oxford, where he was scholar from 1848 to 1853; Fellow from 1853 to 1860; Lecturer in 1854; and Tutor from 1855 to 1856. Professor Stephens, who graduated B.A. in 1852 and M.A. in 1855, accepted the post of headmaster of Sydney Grammar School, and held it for ten years, when he founded The New School (Eaglesfield from 1879), which he conducted with success for fifteen years.

Taxa Named By Johann Georg Wagler
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nota Bene
(, or ; plural form ) is a Latin phrase meaning "note well". It is often abbreviated as NB, n.b., or with the ligature and first appeared in English writing . In Modern English, it is used, particularly in legal papers, to draw the attention of the reader to a certain (side) aspect or detail of the subject being addressed. While ''NB'' is also often used in academic writing, ''note'' is a common substitute. The markings used to draw readers' attention in medieval manuscripts are also called marks. The common medieval markings do not, however, include the abbreviation ''NB''. The usual medieval equivalents are anagrams from the four letters in the word , the abbreviation DM from ("worth remembering"), or a symbol of a little hand (☞), called a manicule or index, with the index finger pointing towards the beginning of the significant passage.Raymond Clemens and Timothy Graham, Introduction to Manuscript Studies (Ithaca: Cornell University Press, 2007), p. 44.

Gerard Krefft
Johann Ludwig (Louis) Gerard Krefft (17 February 1830 – 19 February 1881), a talented artist and draughtsman, and the Curator of the Australian Museum for 13 years (1861-1874), was one of Australia's first and most influential zoologists and palaeontologists. According to Macdonald, et al. (2007), Krefft "was among the first to raise the alarm" in relation to "the devastating effects" of the invasive species, such as "sheep, cats, etc., on native species". Also, along with significant others, such as the proprietor of the Melbourne ''Argus'', Edward Wilson, Krefft expressed considerable concern in relation to the effects of the expanding European settlement upon the indigenous population. In addition to his numerous scientific papers, his publications include ''The Snakes of Australia'' (1869), ''Guide to the Australian Fossil Remains in the Australian Museum'' (1870), ''The Mammals of Australia'' (1871), and ''Catalogue of the Minerals and Rocks in the Australian Museum' ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
