NERITA globosa. 
TAB. CCCCXXlV.—flg. 1. 
Spec. Char. Subglobose, transversely ml- 
catecl ; spire apparent ; one tooth upon the 
inner lip ; outer lip plain within. 
Three or four black bands and a few rows of oblong 
spots decorate the surface : the outer lip is rather thin 
and void of crenulations ; the inner lip is narrow, with 
only one very obtuse tooth near its upper end ; within 
the aperture near its lower part, is a conspicuous lamel- 
liform tooth that regulates the opening of the operculum 
by confining the appendage that moves between it and the 
lip : the spire is not prominent. 
The only circumstance in the form of this shell that 
induces us to determine it to be a Nerita, is the sulcated 
surface in which it agrees with many recent marine 
Shells, that have like it, no teeth or crenulations on the 
outer lip, but are still called Neritee ; being a fossil and 
much corroded, it may have lost its epidermis, although 
some colour remains. 
This unique specimen was lent us by the Rev. T. 
Cooke, who has taken much pains to fill up our list of 
Hampshire shells : it contained two valves of Corbula 
Pisum (tab. 209.) an intimation of its marine origin.
