Sottog. LISSOCHLAMYS SACCO 1897
(tipo L. excisa (BRN.)) Il nome proposto è in sostituzione di Pyxis MENEGH. in DE STEF. 1877, nome che non può assolutamente conservarsi preesistendogli (1º) Pyxis CHEMN. 1784 usato per un Pecten dapprima (Neu. Syst. Conch., p. 299) e poi (id. id., p. 301) per un Brachiopodo: (2°) Pyxis BELL 1815 proposto per una Testuggine, e (3°) Pyxis DEJ. 1834 usato per un Coleottero. Veggasi la diagnosi specialmente nel lavoro del FORESTI (1889. Del Gen. Pyxis MENEGH. ecc.). Per alcuni caratteri ricorda i Pseudamussium.»

«Genus Lissochlamys Sacco, 1897
Lissochlamys Sacco, 1897a: 102 (as a subgenus of Chlamys).Type species (by original designation): Pecten excisus Bronn, 1832; Lower Pliocene, Val d'Andona, near Asti, Italy.
Diagnosis.— Non-cemented orbicular Palliolini with prominent antimarginal microsculpture. Radial macrosculpture nearly absent. No shagreen microsculpture or commarginal macrosculpture. Byssal notch deep throughout ontogeny; byssal fasciole deeplying. Ctenolium well developed.
Distribution.— Upper Miocene to Recent; western Europa (fossil) and tropical eastern Atlantic (Recent); littorally to subüttorally.
Remarks.— Hertlein (1969: N354) treated Lissochlamys Sacco, 1897, Delectopecten Stewart, 1930, Hyalopecten Verrill., 1892 and Parvochlamys Sacco, 1904, as subgenera of Palliolum, placed in the Ebumeopectm-group. All but one of these so-called subgenera of Palliolum can be treated as distinct genera, placed in other suprageneric taxa. Waller & Marincovich (1992: 219) considered Palliolum a genus of the subfamily »
