Description. Shell small for genus (to 88.2 mm SL), fusiform, with 9 whorls including protoconch. Protoconch unknown, damaged or missing on all specimens. Teleoconch of about 8 expanding whorls bearing axial ribs, spiral cords, a nodular periphery, straight suture, slightly concave sutural ramp, and modest siphonal process. Axial sculpture of 6-7 broad ribs extending suture to suture on first 3-5 adapical whorls, transitioning to prominent, node-like peripheral ribs on later whorls. Fine spiral cords 5 on early whorls, increas- ing to about 16-18 cords on body whorl; body whorl sub- quadrate, angled at anterior periphery and at junction with base; sutural ramp with 8-10 flattened, alternately large and small spiral cords; periphery band-like, formed of 9-12 round nodes that diminish in size toward edge of lip in larger speci- mens; 5-6 spiral cords between periphery and posterior angle, largest 2 cords at and near posterior margin; base with 1-2 large spiral cords flanked by single threads. Siphonal process short and broad for genus, with about 4 coarse transverse cords extending to tip, sometimes with single finer threads between cords. Aperture subquadrate, angled at anterior and posterior peripheral cords; outer lip crenulated by termini of larger cords of body whorl; anal sinus indistinct, bordered by interior cord emerging onto generally adherent parietal shield; inner lip thin, separated from shield abapically, continuing separated into siphonal canal. Siphonal canal typically open, canted slightly left, usually slightly sinuous. Exterior shell color cream with irregular light to dark brown axial streaks, largely confined to spaces between ribs and to siphonal process; space between peripheral nodes often marked by large, dark brown spot; shell interior white. Operculum caramel brown, ovate, filling aperture, typically fusinine. Periostracum olivaceous, very thin. Radula unknown. Distribution. Northern New South Wales to central Queensland, eastern Australia. Etymology. The name commemorates Australian naturalist Charles Hedley (1862-1926), who first drew attention to the species. Remarks. Marmorofusus hedleyi spec. nov. has a smoother shell with a brighter white primary color than M. brenchleyi or M. natalensis, both of which it resembles; like those species, dark brown spots and axial streaks pass between peripheral nodes, rather than over them as they do on shells of M. nicobaricus. Measurements to date indicate that the maximum size of M. hedleyi spec. nov. is smaller than that of M. brenchleyi or M. natalensis (88.2 vs. 109.5 & 133.4 mm SL), and the spire is relatively taller and more slender than those of the latter two species. The species seems to be found most often in shallow water, prompting us to question the single record labeled as having been taken in 60-80 m. Angas (1877) listed this species as Fusus laticostatus Deshayes, 1831 in a checklist of New South Wales Mollusca; that error is understandable as markings on shells of both species are similar. Although brown axial streaks occur on both, shells of M. hedleyi spec. nov. are much smaller than those of F. laticostatus, which attains at least 175.4 mm (WLC); shells of the latter species also differ by being less markedly concave between whorls; the peripheral cord on the body whorl is smooth or bears only inconspicuous nodes; and the angle between the posterior part of the body whorl and the base is marked by only a single broad, low, smooth cord. The new species was included in another check-list of New South Wales Mollusca by Hedley (1918), who referred the shell to Fusinus turrispictus (originally Buccinum turris picta) Martyn (1786: figs. 90). Hedley also suggested synonymies with Fusus variegatus (Perry, 1811), Fusus oblitus Reeve, 1847, and Fusus laticostatus 'Angas, 1877'. The Martyn name, originally non-binominal and unavailable, was validated by Hedley as Fusinus turrispictus, based on his ref- erence of the name to Martyn's two figures. Hedley applied the name to the Australian species despite von Martens (1872: 31) earlier contention that Martyn's figure depicts Fusus oblitus Reeve (1847 in [1847-1848]: pl. 7, fig. 29). We reject that synonymy also, and consider the Martyn figures too stylistic to relate with certainty to any Fusinus species. We regard F. oblitus from the Mascarene Islands and F. lati- costatus from the Bay of Bengal as distinct species-level taxa, with F. variegatus a possible earlier name for F. laticostatus.
