Glossoidea : Vesicomyidae
Tebble name: n/a
Smith & Heppell name: Vesicomya atlantica (E A Smith, 1885)

To size: To 4mm. Shell Structure: Thin, shiny. Equivalve: Equivalve. Equilateral: Slightly inequilateral, beaks just in front of midline. Tumidity: Very tumid. Outline: Subcircular, very slightly longer than high; posterior slightly broader than anterior; posterior dorsal slope long, distinct, gently curved, junction with posterior margin slightly angular; posterior, ventral and anterior margins broadly curved. Contour: Lunule not depressed, demarcated by a distinct groove that interrupts the margin; escutcheon prominent, the entire length of the posterior dorsal margin, edges angular.

Sculpture: Of distinct evenly spaced concentric ridges over the later parts, smooth initially. Ligament: External, small. Hinge: Teeth variable in prominence but weak; LV with a single oblique cardinal below the beak angled across the hinge plate (4b), anterior to 4b a sinuous tooth lying parallel with the hinge plate composed of two parts, the first an s-shaped lamina (probably joined 2b2/2a) joined to the second, a weak ridge (probably the lateral AII); a large socket lies above the combined tooth. RV with a sinuous laminar tooth below beak (probably combined cardinals 3a/1/3b) and a small anterior isolated tooth (probably lateral AI). Pallial Musculature: Mostly obscure. Periostracum: Thin, obscure. Colour: White.
