Beguina variegata   Bruguiere  (Clam)
Organism information awaits expert curation
Class: Bivalvia

Color : Dull whitish with brownish, crescent-shaped spots

The shell is thick, solid, rather strongly inflated and oblong in outline, with a terminal umbo situated at the front end. The front margin of the shell is slightly indented, the lower margin straight and the dorsal and hind margins evenly rounded. The shell is sculptured with broad, strongly developed ribs radiating from the umbo. These ribs bear on their surfaces numerous overlapping scaly processes, which are small and close-set on the anterior ribs, but become larger and more spaced on the comparatively stout posterior ribs. On the inner surface the pallial line and the adductor impressions are indicated by well marked depressions and the margin appears strongly undulated owing to the presence of the strong external ribs.
