Tue nature of the animal inhabiting the shell of Lingula 
remained unknown, until the illustrious Cuvier detected its 
affinity with Terebratula, Crania, and those singular bi- 
valve 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 pecu- 
liarities 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. f 
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.
