Shell ovate, lengthened, convex, coveredwith a dusky cuticle, striated by the layers of growth; rounded andeffuse anteally, ending retrally in a short spine, with a slightly prominentknob ; margin of the opening entire, subquadrangular.— This species was observedby Mr T. Drummond (at present engaged in exploring the ArcticBotany of North America) in 1812, in the nursery grounds of Messrs Sweetand Miller. Specimens were transmitted by Dr Leach to Baron Ferussac.It feeds on the earth worm, into the holes of which it effects its entrance.Eggs few, ovate.

The specimens obligingly presented to me by Mr J. C.Sowerby, incline me to consider them as identical with the species long ago describedby Draparnaud. In the description Mr G. B. Sowerby adds, " theanimal of this species bears a near resemblance to that of T. haliotoidea, nothaving the double row of tubercles running from the head to the anteriorpart of the shell so conspicuous in T. Maugii."COCHLEAD.E.Gen. XVI. CYCLOSTOMA.—Peristome of the shell thickened,entire. Tentacula linear, subretractile, the secondpair minute, bearing the eyes.— 52.
