Excerpt: Daboia is a monotypic genus of venomous Old World viper. The single species, D. russelii, is found in Asia throughout the Indian subcontinent, much of Southeast Asia, southern China and Taiwan. It is a member of the big four venomous snakes in India. It is one of the species responsible for causing the most snakebite cases and deaths in the world due to various factors such as its frequent occurrence in places where humans are occupied. The species was named in honor of Patrick Russell (1726-1805), a Scottish herpetologist who first described many of India's snakes; and the genus is after the Hindi name meaning "that lies hid", or "the lurker." Two subspecies are currently recognized, including the nominate subspecies described here. This snake can grow to a maximum length of 166 cm (5.5 ft) and averages about 120 cm (4 ft) on mainland Asian populations, although island populations do not attain this size. It is more slenderly built than most other vipers. Ditmars (1937) reported the following dimensions for a "fair sized adult specimen": The head is flattened, triangular and distinct from the neck. The snout is blunt, rounded and raised. The nostrils are large, in the middle of a large, single nasal scale. The lower edge of the nasal touches the nasorostral. The supranasal has a strong crescent shape and separates the nasal from the nasorostral anteriorly. The rostral is as broad as it is high...
