Description. Shell subcircular, fragile, pellucid, inequilateral, large, up to 65 mm in length, umbones opisthogyrate and moderately inflated; anterodorsal margin straight, posterior very short; anterior end rounded, posterior area delimited by a line from the umbones to middle posterior end; siphonal gap formed by shell folds; external surface with concentric ridges more conspicuous along the umbonal area (Figs.10 A–D); internally white with a deep and high pallial sinus of about half of shell length; right hinge with two unfused cardinal teeth (3a & 3b), one anterior lateral tooth (AI) aligned with the 3a; one posterior lateral tooth (PI) short (Fig. 10 E); left hinge with Vshaped cardinal tooth (2a & 2b), 2b more elongated, one anterior and one posterior lateral teeth (AII & PII) complete the hinge (Fig. 10 F).

Remarks. Anatina Schumacher, 1817 (Mactridae) has priority over Anatina Lamarck, 1818 (Laternulidae). Lamarck (1818) latinized the French name “Anatine” previously published (Lamarck, 1809). However, some authors (e.g. Olsson, 1961; Vokes, 1967) considered Anatina Lamarck sensu Bosc (1816) as valid who mentioned correctly the genus of Lamarck but citing in vernacular only one species (le solen canard, nomen nudum). The nomenclatorial problem of this genus was resolved by Keen (1961).
Anatina anatina (Spengler, 1802) is a valid mactrid species living along the western Atlantic Ocean. The examination of the type material and original illustrations confirm that Anatina pellucida Schumacher, 1817 (Fig. 11 A), Lutraria lineata Say, 1822 (Figs. 11 B–D), Mactra papyracea Lamarck, 1818 (not Gmelin, 1791), Mactra recurva Wood, 1828 (Fig. 11 E–H) and Mactra nuttallii Reeve, 1854 (vol. 8, pl. 21, sp. 125, not Conrad, 1837) are synonymous species names. The Pacific species Anatina cyprinus (Wood, 1828) had been cited widely as synonym of A. anatina (see, e.g., Dall, 1894b; Wilkins, 1957; Keen, 1958; Olsson, 1961). However, A. cyprinus from the Eastern Pacific coast is more subcircular, less elongated and has smaller posterior gap than the Atlantic A. anatina (Figs. 11 I–J).
