«Genus Gloripallium nov.
Type: Ostrea pallium Linné.
This species recalls the Chlamydoid series at sight, but is very distinct in its stouter build, its strong hinge and its essentially different sculpture. The very juvenile is concentribally finely striate, radials developing later with the striae persisting in the intervals. Then, upon the radials, grow regular distant fluted scales, and smooth radials appear in the interstices, the striae still continuing even when two or three radials intervene; on the left valve the sculpture is a little dissimilar in its growüh though reaching the same adult appearance, all the ribs developing strong scutes which become trifold on the main ribs, the intervening minor riblets also becoming scutellate. Both valves are convex, of about the same convexity. The ears are unequal but similarly strongly scaly. The hinge is stout, the cardinal crura consisting of two very strong diverging very rugose ribs, a smaller ridge bounding the ligamental pit on each side; the pit is broad but the ligament is not very large. A definite groorre appeam below the cardinal crura on the outer edge of each ear, forming a tubular aperture, when the valves are closed. The auricular crura are strong interlocking ridges, a deep byssal groove concluding in the left ear with a nodulose ridge intervening with a couple of linear nodules succeeding.»

«Gloripallium Iredale, 1939
Gloripallium Iredale, 1939: 357. Type species (by original designation): Ostrea pallium Linnaeus, 1758; Recent, Indonesia.
Diagnosis. Medium-sized Decatopectinini with 7–14 radial plicae; subcircular to circular; with prominent commarginal lamellae on plicae; secondary sculpture of radial riblets (lacking from some specimens); noduliferous radial macrosculpture on auricles, commarginal microsculpture on auricles and on disc in early growth stage of some specimens; internal rib carinae prominent; hinge with prominent dorsal teeth and weak resilial teeth; byssal notch deep, ctenolium well-developed.
Distribution. Miocene–Recent (Hayami, 1989: 15). Tropical Indo-West Pacific, living in the littoral to sublittoral zones amongst coral on soft sediment
Discussion. Hertlein (1969: N357) treated Gloripallium as a subjective junior synonym of Cryptopecten Dall, Bartsch & Rehder, 1938, a subgenus of Chlamys Röding, 1798, placed in the Chlamys group. Waller (1986: 40) recognized Gloripallium as a valid genus in Decatopectinini.»
