“Limopsis marionensis, n. sp. (Pl. XVIII. figs. 2-2b).
Testa valde inæquilateralis, crassiuscula, oblique ovata, postice paulo angustata, latere antico late arcuato, postico subacute rotundato. Valvæ probabiliter albidæ, epidermideque hirsuta amictæ, striis tenuibus numerosis radiantibus aliisque concentricis decussatæ. Area ligamenti profunda, excavata. Dentes cardinis numerosi, circiter 20-24.
This is a larger and more solid species than Limopsis straminea, and differs from it also both in form and sculpture. It is not dilated posteriorly like that form, but on the contrary is even faintly pointed or at all events more sharply rounded. The sculpture is much stronger, and the hinge-teeth are more numerous.
Length 28 mm., height 22, diameter 12.
Habitat.—Station 145, Marion Island, in 140 fathoms, and Prince Edward Island, in 100 to 150 fathoms.
All the specimens of this species which were obtained are old dead valves, and in poor condition, but retain sufficient of their characters for description.”
(Smith, 1885: 254)
