Shcll cylindrical, of a brown colour, and cxlrcmely glossy; body somcwhat shorter than the spirc; which consists of fivc ncarly llat volutions, dccrcasing but little in diameter, cxcept the two uppcr oncs, which are a littlc lcss, somewhat paler, and terminating in a blunted apex; volutions divided by a well marked suture, ancl covered with remole, regular, longitudinal s triro, which are invisible without thc aid of a slrong lens; aper- ture subovate ; pillar lip slightly reflected 011 the columella, with a sma\l subum).¡ilicus behind; outer lip thin, and even. L ength about thc tenth of an inch ; diameler nearly a sixth. Found in damp situations amongst moss and jungcrmannire. 2. AcME !IIIN0TA, pi. XIV, f. 26.-First Ed., pi. 41, f. 26. Shell cylindrical, smooth, shining, and of a greenish-brown colour ; spire consisting of four slightly raised volutions, sepa- rated by a. wcll markcd suture, and tcrminaling in an obtuse apex ; aperture subovate ; pillar lip slightly reílected on the columella; outer lip thin, and even on the edges. Length about the tenth of an inch ; diameler not a sixth. I found this minute species at Douglas Castle, Lanarkshire, amongst j ungcrmannire, in the low mcadow !ami bclow th e old tower. This species may be distinguished from the A . f11sca by being longer in proportion t o its breadth, in the volutions being more inflatcd, and in being entirely deslitule of spiral strire. S ection II-Animals withfou,• tentacitla. GENUS 45-SuccINEA,-Drapernaud. Shell subovatc, or ovately conical, mostly elongated; spirc short; aperture longitudinal, oblique, large, entirc, and usually about two-thirds the length of thc shell ; margin of the outer lip thin, sharp, and not reflected, united to the columcllar lip below; columella smooth, sharp-edged, narrow, and altenuated; inner lip spreacl over a small portion of thc body volution. The shell3 of this genus are distinguishcd from the L9m110Ja, by being destitute of the oblique fold on thc columella. l. Succ1NEA AMPHIDIA, pi. XIV, f. 41, 42~First Ed., pi. 42, f. 41, 42.

Vm·ietg 1, pi. XVIII, f. 22, 23. This elegant raricty of thc species was found at Beaumaris, Anglcsca, North \Vales, by my friencl Thomas Glovcr, Esq., of Smeclley Hill, Manchester. It is much thicker in proportion to its sizc, and of a dccp llesh colour ; the spirc is also more inílated than the orclinary spc- cimens. T his shell seldom attains the same sizc as the S. ampltibia, and may readily be distinguishecl by its very oblique apcrturc, and in being more elongated. It inhabits the banks of ponds, rivers, and strcams. 3. SuccINEA OBLONGA, pi. XVIII, f. 21.

Lcmgth a quarter of an inch; diametcr not an eighth of an inch. Found on the margin of clitchcs at Bathgatc, Lanarkshirc, by Mr. Kenyon of Prcston ; al Britonfcrry, near Swansea, by Mr. Jeffrcys; and near Bcrwick-upon-Tweed, by Dr. Johnston. GENUS 46.-AcHATINA.-Lamarck. Shcll ovate, or oblong; body large ; spire short in most specics, but it is sometimes lcngthcned and elevated; aper- ture cntire, longitudinal ; outer lip thin, never reflectcd; inner lip but slightly spread ovcr the base of thc body; columella smooth, and clcstitute of folds or teeth, and truncated at the base. Distinguished from Bulim11s by the abrupt termination of thc pillar lip. '
