80 RAMBLES IN SEAECH OF SHELLS. 



not nearly so flat as the four last-named species, 

 but yet is not so globular as that of the common 

 garden snail, as])ersa, or the apple snail, pomatia, 

 being more compressed above and below. It is 

 almost of a uniform white or fawn colour, although 

 sometimes marked with a light but indistinct spiral 

 band, which is placed a little above the periphery, 

 and does not extend much beyond the last half of 

 the body whorl. In the same localities mentioned 

 for lapic'ida we have found the Kentish snail 

 not uncommon, and this is especially the case 

 in the neighbourhood of Keigate. A much smaller 

 mollusc is Helix cartusiana (PI. IX., fig. 10), 

 so called from having been first discovered near 

 a Carthusian monastery. It has a more solid 

 and nearly opaque shell, that is, much less glossy 

 and transparent than cantiana, of a light brown or 

 fawn colour, generally encircled with a whitish spiral 

 band, placed a little above the periphery. It is 

 generally found attached to grass stems and weeds in 

 the hollows of the downs, and is tolerably common. 



procured them on the line of the old Eoman road which 

 intersects onr heath district, and there is no doubt that they 

 occur all along the stony district of Lincolnshire."
