Walter E. Collinge, British biologist, was educated at Huddersfield College and at Yorkshire College, Leeds (part of Victoria University, Manchester), where he was awarded the Degree Master of Science (MSc). His main interest was in malacology (the study of molluscs) and as early as 1890 he established the Journal of Malacology, which he edited until 1905. In 1891 he was appointed demonstrator in biology at the University of St Andrews, Scotland, where he continued his studies and obtained the degree Doctor of Science (DSc). In 1900 he became a lecturer in zoology and comparative anatomy at Victoria University, Birmingham, a post he held until 1921. From 1905 to 1915 he was the editor of the Journal of Economic Biology. During 1915-1917 he was a Walker Trust Research Fellow, and during 1916-1919 a Carnegie Fellow. In 1919 he was also a Research Fellow and lecturer in comparative embryology at the University of St Andrews. He founded the Association of Economic Biologists, and for many years served as president of the Midland Malacological Society. From 1921 to 1941 he was the keeper of the Yorkshire Museum, and from 1942 to 1947 president of the Northern Ecological Association. He was a Fellow of both the Linnean Society and the Entomological Society of London.
Collinge's most important publications were The skull of the dog (a manual for students; London, 1892, 124p), A manual of injurious insects (Birmingham, 1912, 268p) and The food of some British wild birds: A study in economic ornithology (London, 1913, 109p). In addition he published numerous papers on molluscs, including descriptions of new species; fishes (living and fossil), including several on their sensory canal system; and comparative anatomy. His first paper relating to southern Africa was " On a collection of slugs from South Africa, with descriptions of some new species" in the Annals of the South African Museum (1900, Vol. 2(1), 8p). This was followed by "On a further collection of South African slugs, with a checklist of known species" (1901, Vol. 2(8), 8p) and "Description of a new species of Onichidium from South Africa..." (Journal of Malacology, 1902). Later he reported on the slugs and terrestrial Isopoda (an order of crustaceans including woodlice) of Natal in "The slugs of Natal" (Annals of the Natal Museum, 1910, Vol. 2(2), pp. 159-174) and "Contributions to a knowledge of the terrestrial isopoda of Natal" (Ibid, 1917, Vol. 3(3), pp. 567-586; 1919, Vol. 4(1), pp. 229-234; and 1920, Vol. 4(2), pp. 471-490).
