Trophon eversoni n. sp. is described. The new species is morphologically close to T. geversianus (Pallas, 1774), T. scotianus Powell, 1951, T. plicatus (Lightfoot, 1786), T. longstaffi Smith, 1907, T. leptocharteres Oliver & Picken, 1984, and T. albolabratus Smith, 1875, but differs in having a larger shell, more numerous and regularly shaped spiral cords, and high, thin, abaperturally sloping axial lamellae.
