William Henry Benson (1803–1870) made extensive collections of Mollusca, particularly land snails, from South Africa, Mauritius, and especially from the Indian subcontinent, where he spent his working life in the service of the East India Company. Details of this malacological network are provided, together with a biography of Benson himself and a history of his pioneering role as a malacologist in British India. In a series of papers published between 1829 and his death in 1870, Benson introduced 471 species-level names belonging to 60 families of gastropod and 8 families of bivalve, and in addition introduced names for 32 genus-groups. Of the 102 genus-group names described with Benson species as their types, 70 are currently recognised.
