larger; 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 strise being the 

 larger.

A species somewhat resembling C. ligatuniy 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 strise 



decussating the spiral strise, and the posterior strise 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.

Bulimus irroratus. Bui, testd acuminato-oblongdy medio ven-

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 

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

 flesh-pink.
