''True Vipers: Natural History and Toxinology of Old World Vipers''. Malabar, Florida: Krieger Publishing Company. 359 pp. . Like all other vipers, it is venomous. No subspecies are currently recognized. Etymology The specific name, ''macmahonii'' (or ''macmahoni'' ), is in honor of British diplomat Arthur Henry McMahon. Description ''E. macmahonii'' is a relatively small species growing to a total length (including tail) of less than . Males are in total length, the females .

Alfred William Alcock
Alfred William Alcock (23 June 1859 in Bombay – 24 March 1933 in Belvedere, Kent) was a British physician, naturalist, and carcinologist. Early life and education Alcock was the son of a sea-captain, John Alcock in Bombay, India who retired to live in Blackheath. His mother was a daughter of Christopher Puddicombe, the only son of a Devon squire. Alcock studied at Mill Hill School, at Blackheath Proprietary School and at Westminster School. In 1876 his father faced financial losses and he was taken out of school and sent to India in the Wynaad district. Here he was taken care of by relatives engaged in coffee-planting. As a boy of 17 he spent time in the jungles of Malabar. Career Coffee-planting in Wynaad declined and Alcock obtained a post at a commission agent's office in Calcutta. This office closed soon, and he worked from 1878 to 1880 in Purulia as an agent recruiting unskilled labourers for the Assam tea gardens. While here an acquaintance, Duncan Cameron, le ...

Venomous Snake
Venomous snakes are Species (biology), species of the Suborder (biology), suborder Snake, Serpentes that are capable of producing Snake venom, venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The venom is typically delivered by injection using hollow or grooved fangs, although some venomous snakes lack well-developed fangs. Common venomous snakes include the Family (biology), families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine , while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of venom delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake venom may have both neurotoxic and hemotoxic properties. There are about 600 venomous snake species in the world. Evolu ...

Keeled Scales
Keeled scales refer to reptile scales that, rather than being smooth, have a ridge down the center that may or may not extend to the tip of the scale, Campbell, J. A., Lamar, W. W. (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 870 pp. 1,500 plates. . making them rough to the touch. According to Street's (1979) description of European lizards and snakes, in those that have keeled scales the keels are usually stronger in male specimens and are consistently arranged according to the species of reptiles, even though many others do not have them. With European lizards, the dorsal scales are usually well keeled, while those on the flanks are more weakly keeled and those on the belly smooth. Street, D. (1979). ''The Reptiles of Northern and Central Europe''. London: B.T. Batsford Ltd. 268 pp. . Non-European lizards such as ''Sphaerodactylus macrolepis'' also display keeled scales. Klauber (1997), describes how the keels on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Circumorbital Ring
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''.

Henry McMahon (diplomat)
Sir Arthur Henry McMahon (28 November 1862 – 29 December 1949) was a British Indian Army officer and diplomat who served as the High Commissioner in Egypt from 1915 to 1917. He was also an administrator in British India and served twice as Chief Commissioner of Baluchistan. McMahon is best known for the McMahon-Hussein Correspondence with Hussein bin Ali, Sharif of Mecca, the McMahon Line between Tibet and India, and the Declaration to the Seven in response to a memorandum written by seven notable Syrians. After the Sykes-Picot Agreement was published by the Bolshevik Russian government in November 1917, McMahon resigned. He also features prominently in ''Seven Pillars of Wisdom'', T.E. Lawrence's account of the Arab Revolt against the Ottoman Empire during World War I. Early life McMahon was the son of Lieutenant-General Charles Alexander McMahon, FRS, FGS (1830–1904), a geologist and Commissioner of both Lahore and Hisar in Punjab, India, and who, like his father ...
