Designation of lectotype for Haliotis crebrisculpta Sowerby, 1914, with a discussion of H-clathrata Reeve, 1846 (non Lichtenstein, 1794)

The three syntypes of Haliotis crebrisculpta Sowerby, 1914, belong to two s pecies. The figured specimen of Sowerby (BMNH 1919.12.31.19) is designated as lectotype. This species remains known from a single shell from New Caled onia. It is characterized by the eccentric apex (1/7.2 from the posterior m argin of the shell) of the oblong shell and its strong spiral cords bearing numerous scales. The other two specimens in the syntype series of H. crebr isculpta are referable to H. clathrata Reeve, 1846 (non Lichtenstein, 1794) . Haliotis clathrata Reeve has been poorly identified in the literature. It is redescribed on shell, radular, and epipodial characters. Haliotis clath rata is not a subspecies of H. rubra Leach, 1814, but the fossil H. tuvutha ensis Ladd in Ladd & Hofmeister, 1945, is synonymized under it. The species ranges from Madagascar to American Samoa and from southern Japan to the Sy dney area of southeastern Australia.
