Named in 1951 by Keith Norrish in honor of Rex Tregilgas Prider (22 September 1910, Narrogin, Western Australia - 6 October 2005, Perth, Western Australia), Professor of Geology at the University of Western Australia. He studied the leucite lamproites of the northern Canning Basin, work that eventually led to the development of the Kimberley diamond mining region. He also served as President of the Geological Society of Australia.
