216 HELICID/E. 



Drap.) is in Dr. Turton^s collection of British shells, 

 marked '^ Cornwall " (the birthplace of many spurious or 

 exotic shells) ; but although it has not at present any 

 well-founded claim to British parentage, it is remarkable 

 that this characteristic species, which had been so long 

 considered as peculiar to the shores of the Mediterranean, 

 has been lately found by M. TAbbe Maillard at Beauvais 

 in the North of France ; and I have seen the specimens 

 and been satisfied as to the correctness of this discovery.

Body greyish-white or yellowish, with sometimes a tinge of 

 reddish-brown ; tubercles very close-set ; mantle marked with 

 rather small and irregular, but distinct, milk-white specks : 

 tentacles rather long and thick, distinctly granidated, of a yel- 

 lowish-grey colour ; bidbs globular : foot slightly angulated in 

 front, its sides having a narrow whitish border, and the tail 

 tapering to a blunt point. 



Shell nearly circular, much compressed above, but not quite 

 so much below, rather thin, but nearly opaque, glossy, whitish 

 or cream- colour, with usually a rather broad chestnut band a 

 little above the periphery, and from two to six narrow bands of 

 the same colour below it, but all these bands (or some of them) 

 are often interrupted or altogether wanting ; scidpture con- 

 sisting of faint strise in the hue of growth, and often of irre- 

 gular pit-marks or indentations, which are thickly scattered 

 over the siuface : periphery round, and not in the least keeled 

 or angular: epidermis verj^ thin: whorls 6, cyhndrical, the 

 last occupying about thi-ee-fifths of the shell : spire very slightly 

 raised, chestnut-brown at the summit : suture deep : mouth 

 nearly round, forming a segment of about four-fifths of a 

 circle, somewhat oblique, in consequence of the greater pro- 

 minence of the upper hp, and occasionally strengthened by a 

 slight internal rib: outer lip rather thick, slightly reflected 

 and especially towards the columella, very abruptly inflected
