The Sir Alfred Lewis Prize is awarded, according to https://www.bangor.ac.uk/news/archive/prize-winners-2015-23505 to “to the best single or joint honours student in SBS excluding biology or biomedical science”. My father, Roger Lines, was awarded it in 1952, when what is now Bangor University was “The University College of North Wales”.
