George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Balangoda
Balangoda is a large town in Ratnapura District, Sabaragamuwa Province, Sri Lanka, governed by an urban council located away from Colombo and from Ratnapura on Colombo - Batticaloa Highway(A4). It is one of the largest towns of the Sabaragamuwa Province. According to the 2001 census, Balangoda has a population of 16,875 and area of . Balangoda is notable due to the discovery of skeletal Hominini remains from the late Quaternary period (the earliest reliably dated record of anatomically modern humans in South Asia). The town is also the birthplace of Balangoda Ananda Maitreya Thero and Sirimavo Bandaranaike (the world's first female head of government) the Prime Minister of Sri Lanka (1960–65, 1970–77 and 1994–2000). Balangoda is situated in the hilly central region of central Sri Lanka on Sabaragamuwa Mountain Range. The main livelihoods of this region are farming (vegetables, fruits, and spices), rice cultivation for mainly local consumption, tea cultivation for interna ...

Reptiles Described In 1904
Reptiles, as most commonly defined are the animals in the Class (biology), class Reptilia ( ), a paraphyletic grouping comprising all sauropsid, sauropsids except birds. Living reptiles comprise turtles, crocodilians, Squamata, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean taxonomy, Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern Cladistics, cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile Order (biology), orders, historically combined with that of modern amphi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frank Wall (herpetologist)
Colonel Frank Wall (21 April 1868 – 19 May 1950) was a physician and herpetologist who lived in Sri Lanka and India. Early life and education Wall was born in Colombo, Ceylon (now Sri Lanka). His father, George Wall, was responsible for initiating the study of natural history on the island. Wall was sent to England to be educated at Harrow School, the same school his father and brothers attended, and studied medicine in London before joining the Indian Medical Service in 1893.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Wall", p. 279). Herpetology Sent to India under the British Raj, Wall continued to work there until 1925 and researched many animals, especially snakes. He collected numerous snakes, many of which are now in the collections of the British Museum and the Natural History Museum, London. Wall was a member of the Bombay Natural History Society and pu ...

Malcolm Arthur Smith
Malcolm Arthur Smith (1875 in New Malden, Surrey – 1958 in Ascot) was a herpetologist and physician working in the Malay Peninsula. Early life Smith was interested in reptiles and amphibians from an early age. After completing a degree in medicine and surgery in London in 1898, he left for the then Kingdom of Siam (today Thailand) as a doctor to the British Embassy in Bangkok. In 1921 he married Eryl Glynne of Bangor, who as well as being medically trained, made significant collections of ferns from Thailand and later worked at RBG Kew. She was killed in a car crash near Bangkok in 1930. The couple had three children including the mountaineer Cymryd "Cym" Smith, also killed in a road accidenEryl was the elder sister of the mountaineer and plant pathologist Mary Dilys Glynne.

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Subcaudal Scales
In snakes, the subcaudal scales are the enlarged plates on the underside of the tail.Wright AH, Wright AA. 1957. Handbook of Snakes. Comstock Publishing Associates (7th printing, 1985). 1105 pp. . These scales may be either single or divided (paired) and are preceded by the anal scale. Related scales * Anal scale * Ventral scales See also * Snake scales Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints ...

Ventral Scales
In snakes, the ventral scales or gastrosteges are the enlarged and transversely elongated scales that extend down the underside of the body from the neck to the anal scale. When counting them, the first is the anteriormost ventral scale that contacts the paraventral (lowermost) row of dorsal scales on either side. The anal scale is not counted.Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishing Associates, Ithaca and London. 870 pp. 1500 plates. .

Ocular Scales
In scaled reptiles, the ocular scales are those forming the margin of the eye.Wright AH, Wright AA. 1957. ''Handbook of Snakes''. Comstock Publishing Associates (7th printing, 1985). 1105 pp. . The name originates from the term ''oculus'' which is Latin for 'eye' and, in the broadest sense, refers to a scale associated with the eye. The numbers of these scales present, and sometimes the shapes and sizes, are some of many characteristics used to differentiate species from one another. Prefixes are usually included to indicate the positions or locations of the individual scales:Mallow D, Ludwig D, Nilson G. 2003. ''True Vipers: Natural History and Toxinology of Old World Vipers''. Malabar, Florida: Krieger Publishing Company. 359 pp. .Smith MA. 1943.

Dorsal Scales
In snakes, the dorsal scales are the longitudinal series of plates that encircle the body, but do not include the ventral scales. Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 2 volumes. 870 pp. 1,500 plates. . When counting dorsal scales, numbers are often given for three points along the body, for example 19:21:17. These numbers correspond to the number of dorsal scales around the body at a head's length behind the head, at midbody and at a head's length before the vent. If only one number is given, it is for the midbody count. Dorsal scale are easiest to count diagonally, starting with the paraventral scale row. In doing so, it is often noted that certain scale rows are raised, keeled or smooth as opposed to the others.U.S. Navy (1991). ''Poisonous Snakes of the World''. United States Government.

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...
