The nature of the animal inhabiting the shell of Lingula remained unknown, until the illustrious Cuvier detected its affinity with Terebratula, Crania, and those singular bivalve shells forming the order Brachiopoda of Mr. Macleay. The valves have neither teeth or ligament, but are united by muscles, and supported on a fleshy peduncle, three or four inches in length, by which the animal is attached to marine bodies.
We believe that under the common name of Anatina, two species have been included. Their respective peculiarities were published, some time ago, in the Journal above alluded to; and are now more fully illustrated by figures, and by such specific distinctions as are exhibited by the shells. Both species appear to inhabit the Indian Ocean.
LINGULA hians.
Valves narrowed towards their base, convex, and generally smooth; both extremities widely gaping.
We do not recollect to have seen this species so frequent in collections as the preceding; it is always smaller, more convex in the middle, and generally smooth. Mrs. Mawe favoured us with fine specimens of both, for delineation.
