Typhloperipatus Williamsoni
''Typhloperipatus'' is a genus of velvet worm in the family Peripatidae, containing the sole species ''Typhloperipatus williamsoni''. It is the only species in the phylum found in South Asia. The species was discovered in northeastern India in 1911. Discovery The species name was after Noel Williamson, a political officer at Sadiya who was murdered in 1911 along with Dr. J.D. Gregorson. The murders led to an expedition in the Abor region by the British government in India. Stanley Wells Kemp, then an assistant superintendent at the Indian Museum at Calcutta was a zoologist attached to this expedition. Three specimens were found on 29 December 1911 near the gorge of the Dihang River near Rotung. Although the nearest known velvet worm species, from Malaya, are typically found in dead wood, these were found mainly under large stones near the roots of trees. Subsequently some more specimens were found at the mouth of the Sireng stream and another specimen was found when the 32n ...

Stanley Wells Kemp
Stanley Wells Kemp, FRS (14 June 1882 – 16 May 1945) was an English marine biologist. He was born in London, the second of three sons of Stephen Kemp, a professor at the Royal Academy and Royal School of Music. As a boy he took an interest in animals, collecting water beetles and maintaining them in aquariums and was a member of the local natural history society. He studied at St Paul's School and later went to Trinity College in Dublin from where he graduated with a gold medal in 1903. He studied botany under H. H. Dixon. In 1910 he joined the Zoological and Anthropological section of the Indian Museum and when the organization was converted in 1916 to the Zoological Survey of India, he became Superintendent and took up the study of crustaceans to continue work started by James Wood-Mason and Alfred William Alcock. He spent fourteen years in India during which he published seventeen papers on the decapods in the Indian Museum. In 1918 he made a trip to Baluchistan along ...

Onychophora
Onychophora (from grc, ονυχής, , "claws"; and , , "to carry"), commonly known as velvet worms (due to their velvety texture and somewhat wormlike appearance) or more ambiguously as peripatus (after the first described genus, '' Peripatus''), is a phylum of elongate, soft-bodied, many-legged panarthropods. In appearance they have variously been compared to worms with legs, caterpillars, and slugs. They prey upon other invertebrates, which they catch by ejecting an adhesive slime. Approximately 200 species of velvet worms have been described, although the true number of species is likely greater. The two extant families of velvet worms are Peripatidae and Peripatopsidae. They show a peculiar distribution, with the peripatids being predominantly equatorial and tropical, while the peripatopsids are all found south of the equator. It is the only phylum within Animalia that is wholly endemic to terrestrial environments, at least among extant members. Velvet worms are generally ...

Peripatidae
Peripatidae is a family of velvet worms. The oldest putative representatives of the family herald from Burmese amber dated to the mid-Cretaceous, around 100 Ma, with representatives from Dominican and Baltic amber attesting to a broader distribution in the Palaeogene / Neogene; molecular variability suggests that the family's crown group may have arisen in the early Mesozoic. Description The Peripatidae exhibit a range of derivative features. They are longer, on average, than the Peripatopsidae and also have more leg pairs. The number of leg pairs in the Peripatidae range from 19 (in ''Typhloperipatus williamsoni'') to 43 (in ''Plicatoperipatus jamaicensis''). The gonopore is always between the penultimate leg pair. There are no oviparous species—the overwhelming majority are viviparous. The females of many viviparous species develop a placenta with which to provide the growing embryo with nutrients. Distribution The Peripatidae are restricted to the tropical and subtropical z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sadiya
Sadiya is a town in Tinsukia district, Assam. It was the capital of the Chutia Kingdom and after the downfall of the kingdom it became the seat of the ''Sadiya-khowa-Gohain'' of the Ahom kingdom. Extensive remains of buildings and fortifications built during the rule of the Chutias near Sadiya still point to the importance of the region in the past. Historically Sadiya referred to the Chutiya kingdom which included at times the districts of Lakhimpur, Dhemaji and Tinsukia. It is claimed to be the center of development of the eastern Assamese dialects, the inscription here are written in a Tai script. Its stands on a grassy plain, almost surrounded by forested Himalayan mountains, on the right bank of Lohit River which is locally (but erroneously) considered the main stream of the Brahmaputra River. The deepest point of the Brahmaputra River is located near this village. It is famous for a flower named ''satphul'' (the word means "blessing" or a "desert flower"), which is ...

Malay Peninsula
The Malay Peninsula ( Malay: ''Semenanjung Tanah Melayu'') is a peninsula in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung). The island country of Singapore also has historical and cultural ties with the region.

Phylum
In biology, a phylum (; plural: phyla) is a level of classification or taxonomic rank below kingdom and above class. Traditionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent. Depending on definitions, the animal kingdom Animalia contains about 31 phyla, the plant kingdom Plantae contains about 14 phyla, and the fungus kingdom Fungi contains about 8 phyla. Current research in phylogenetics is uncovering the relationships between phyla, which are contained in larger clades, like Ecdysozoa and Embryophyta. General description The term phylum was coined in 1866 by Ernst Haeckel from the Greek (, "race, stock"), related to (, "tribe, clan"). Haeckel noted that species constantly evolved into new species that seemed to retain few consistent features among themselves and therefore few features that distinguished them as a group ("a self-contained un ...

Umber
Umber is a natural brown earth pigment that contains iron oxide and manganese oxide. In its natural form, it is called raw umber. When calcined, the color becomes warmer and it becomes known as burnt umber. Its name derives from ''terra d'ombra'', or earth of Umbria, the Italian name of the pigment. Umbria is a mountainous region in central Italy where the pigment was originally extracted. The word also may be related to the Latin word ''umbra'', meaning "shadow". Umber is not one precise color, but a range of different colors, from medium to dark in value, from greenish to reddish in hue. The color of the natural earth depends primarily upon the proportions of iron oxide and manganese in the clay. Umber earth pigments contain between five and twenty percent manganese oxide, which accounts for their being a darker and less saturated color than the related earth pigment, sienna. Commercial umber pigments vary in color depending on their origin and how they are processed. Not al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
