1915 Spondylus depressus Fulton, 1915
«Shell moderately thickened, very depressed, upper valve with numerous very slightly raised longitudinal ridges, which on the posterior side bear short spines; colour whitish with dark brown maculations above and a broad margin of purplish-brown at the ventral margin; ligamental area moderately produced; lower valve whitish and roughly scored where it has been attached to rocks; anterior and posterior margins with short close-set colour-lines, as seen in S. ducalis, etc.
Maximum dimensions: Height, 80 mm.; width, 71 mm.; depth or diameter, 21 mm. Hab.: New Caledonia. Three specimens have been examined by me; the largest, taken as type, is somewhat more worn than the two smaller specimens, one of which is lighter and the other darker in colour than the type. Its compressed form and short spines separate it from multisetosus.» HUGH COOMBER FULTON, 1915

«DISTRIBUTION. — West Pacific: New Caledonia, the Philippines. Attached to corals to 230 m.
DESCRIPTION. — Shell height to 75 mm; oblique, depressed shell. Sculpture of short, obsolete, nodulous spining which occurs on the anterior and central part of the mature shell while on the rv where not fixed to the substrate, fine, evenly spaced spines are set in regular rows. Colour white with a broad, concentric band of brown from the centre of the shell to the margin with some brown spotting towards the umbo; anterior and posterior margins near the auricles have colour bars crossing the two margins as in S. sinensis; internally white with a brown crenulated margin and hinge.
REMARKS. — Spondylusdepressus was described by FULTON from three specimens apparently attached to corals from an unknown depth. The specimens collected in this survey are very similar to the holotype. Fulton in his description did not refer to the short, obsolete, nodulous spines that occur on the anterior and central part of the mature shell, while on the rv where not fixed to the substrate, fine, evenly spaced spines are set in regular rows.»
