Spec. Char. NN. Testa ovato-globosd, spird brevi, obtusissimd ; anfractibus tribus, ultimo 
maximo convexo, levigato, aperturd semilunari, ared columellart latissimd, in medio tenut 
dentatd, posterius uniplicatd, labro dextro plano. 
Diameter, + of an inch. 
Localities. Britain: Charlton (S. Wood), Peckham (Meyer). 
France: Lignites, Epernay (Deshayes). 
Specimens of this species do not appear to be very rare from the Woolwich beds, and 
Mr. C. J. Meyer sent me for examination a good series of them. 
So far as Iam able to determine this species, its greatest difference from globulus 
consists in a more elevated spire and in a broad depression on the upper part of the volu- 
tion a little below the suture. It is not so globular. The specimens from near Epernay 
are said to have retained much of their original colour ; “sur le dernier tour on voit trois 
zones transverses inégales, blanchatres sur un fond d’un brun noir quelquefois roussitre ;” 
Desh., Lamarck, 2nd edit. The specimens which I have seen, however, are of one uniform 
colour. 
Neritina pisiformis, Férus., is given by Mr. De la Condamine in ‘ Quart. Journ. Geol. 
Soc.,’ vol. vi, p. 446, and by Mr. Prestwich, ‘ Quart. Journ. Geol. Soc.,’ vol. x, pp. 103 and 
118, as from the Lower Eocene Beds at Woolwich and Charlton, and it is on this authority 
inserted by Mr. Whitaker, as he informs me, in his lists in the ‘Geol. Survey Memoir,’ 
pp. 576 and 579; but I have seen nothing among the specimens of my collecting 
friends which could by that name be specifically distinguished from JV. globulus or from 
LV. consobrina. Probably the shell thus referred to may have been a variety of one or the 
other of these, unless the shell now called WV. jaspidea should be the one intended.
