James Carter first described Neptunus vectensis (now Portunus vectensis) in 1898 from several specimens, two of which were in the Woodwardian Museum, Cambridge, UK. All specimens he studied came from the Hampstead Beds, Isle of Wight, one of which was a partially preserved underside. Unfortunately, none of the specimens which Carter originally used can now be found (Quayle and Collins, 2012); therefore, a recently obtained and better-preserved specimen (IWCMS: 2020.424) is designated as the neotype for Neptunus vectensis and allows to re-describe the species.
