larger 5 and there is a thick keel surrounding the umbilicus ; the 

 suture is distinct and smooth, but belted posteriorly by the middle 

 keel ; the aperture is large, nearly circular, slightly acuminated poste- 

 riorly, with a rather broad reflected peritreme, in which are three 

 little cuts answering to the ends of the external keels ; the umbilicus 

 is large and deep, spirally striated within ; the outer striae being the 

 larger.

2. Cyclostoma aplustre. Cycl. testa suborbiculari, tenuius- 



culd, Icevi, albicante,fasciis nonnullis posticis, anyustis, castaneis, 



subinterruptis, striisque tenuissimis spiralibus, ornatd ; spirdle- 



vatiusculd, subacuminatd, apice obtuso; anfractibus quinis rotun- 



datis, creberrime transversim striatis, striis posticis for tioribus, 



anticis fere obsoletis ; umbilico mayno, intus spiraliter striato, 



striis tenuissimis; aperturd fere circulari, postice paululum 



acuminata, peritremate tenui, acuto, supra umbilicum paululum 



refexo. 



A species somewhat resembling C. ligatum, but differing in several 



characters. It is suborbicular and thin, smooth, whitish, posteriorly 



with several narrow slightly interrupted chestnut-coloured bands and 



close-set very slender spiral striae ; the spire is rather elevated and 



acuminated, but the apex is obtuse : volutions five, very regularly 



rounded, and very finely transversely striated, the transverse striae 



decussating the spiral striae, and the posterior striae being the most 



distinct, the anterior being almost undistinguishable : the umbilicus 



is large, very finely spirally striated within ; aperture large, nearly 



circular, slightly acuminated posteriorly, with a thin, sharp-edged 



peritreme which is rather wide and slightly reflected over a part of 



the umbilicus.

3. Description of a new species of Btjlimus. By Lovell 

 Reeve, F.L.S. 



Bulimtjs irroratus. Bul. testa acuminato-oblonyd, medio ven- 

 tricosd, anfractibus sex, subrotundatis, striis tumidis elevatis 

 interruptis oblique exsculptis, infra suturas peculiariter con- 

 centrice crenulatis, columella stride uniplicatd ; rufescente- 

 purpured, epidermide tenui ciner ascent e, fulvo hie illic punctatd, 

 indutd, columella ccerulescente-albd, labro incarnato-roseo. 



Hab. ? 



This beautiful species, received by Mr. Cuming from A. L. Gubba, 

 Esq. of Havre, is materially distinct from any hitherto described. It is 

 of a swollen ovate form with the spire rather sharply acuminated, and 

 the columella is distinguished by a sharp winding plate. The ground 

 colour of the shell is a reddish purple, the last whorl being particu- 

 larly characterized by a thin ash-coloured epidermis sprinkled with 

 light fulvous spots all inclining towards the lip, which is of a delicate 

 flesh-pink.
