Species oval or sub-orbicular, sub-equilateral.
T. donacina. The Donax-like Tellen. Pl. [9], fig. 5.
Sub-oval, flattish, semi-striated and semipellucid; hinge with two teeth in one valve and one in the other; pale yellow, radiated longitudinally with pink.
T. depressa. The depressed Tellen.
Oval, flat, pointed at the smaller end and slightly reflected; pale yellowish colour, faintly striated concentrically; covered with a pale brown epidermis.
5. Tellinides. One species.
Though this genus bears a great affinity to many others, it cannot be united with any; having lateral teeth, it differs from the Psammobia; by not having the valves twisted, it differs from the Tellina; the valves closing, and having muscular impressions in the interior, render it distinct from the Lucina.
Shell equilateral, rather elongated, almost without the flexuous plait; two cardinal teeth diverging, and two remote lateral teeth, of which the anterior is but little distant from the summit.
T. Timorensis. The Tellinides of Timor. Pl. [8], fig. 3.
The only type and species of this genus.
