Arthur Erskine Ellis (1 October 1902 – 28 February 1983), often known as A.E. Ellis, was a British scientist, biologist and naturalist. Ellis is best known for his large number of malacological publications, including some which became essential texts on the subject of British non-marine malacology. To a lesser extent, Ellis published papers about other land invertebrates and various aspects of the fauna and flora of Britain. In addition Ellis had five ghost stories published.^[1]

Ellis was also a plant collector. From 1919 to 1961 he contributed specimens of spermatophytes to a number of different herbariums in Britain.^[2]

Stella Turk, the British naturalist said about Ellis, "It is difficult to categorise people. Should one even try? We are all multiple in a singular way!"; she also commented, "As might have been expected, he wrote his own obituary in which he gives a broad outline of his life and very lengthy bibliography", (J. Conch. 31 1983).^[3]

Two taxa were named in Ellis' honour:

• Limicolariopsis ellisi Crowley & Pain, 1964 (Rev. Zool. Bot, Afr. 69: 191) -- a large African land snail
• Pisidium (Afropisidium) ellisi Dance, 1967 (J. Conch. 26: 178) -- a small freshwater clam

A.E. Ellis published several books which were the standard reference texts for identifying the non-marine Mollusca of Great Britain and Ireland during most of the 20th century:

• British Snails, a guide to the non-marine Gastropoda of Great Britain and Ireland, Pleistocene to Recent, 1926, reprinted in 1969, Oxford University Press
• Key to Land Shells of Great Britain
• British Freshwater Bivalve Mollusca (Synopses of the British fauna; new series, number 11)
