Rupicola.
Pennant and Donovan described it as Venvs
sinuosa, Lamarck as Anatina 7'upicola, Philippi as Erycina anodon, Anatina ? pusilla, T. ovalis, T. fabula, and
T. elongata, ETeeluz as Rupicola concentrica, and Deshayes as T. brevis. Many other species have been made
by Reeve from Mr. Cuming's specimens of this extremely variable shell. It appears to have been confounded by Kiener with T. corbuloides, Deshayes, on
the supposition that it w^as a smaller form of that
species.
Another species of Thracia [Ainphidesma truncata,
Brown^ or T. ntyopsis, Beck) has been found in glacial
beds, at Greenock by Mr. Stewart Kerr, and at Elie in
Fifeshire by the Rev. Thomas Brow^n. To this species
appears to have also belonged a shell named " Cochlodesma, n. s.^' by Professor King, which was lately
brought up from the depth of 1000 f. or thereabouts,
100 miles west of Cape Clear, by Capt. Hoskyn in
H.M.S. ^Porcupine'; and the fragments of which I
have examined.
T. myapsis now lives only in the
Arctic seas.

the beak in each valve : liinge strong, furnished in some genera
