TAB. LXI.— Figs. 7 and 8»

undulations sharp, slightly waved, most pro- 
minent at the hack . 
Of the oval end the shorter diameter is two-thirds the 
length of the longer; the undulations are very regular, 
bending towards the curve. 
The lightest coloured of these specimens is marie, the 
other Iron-stone; the septa are obliterated in both. 
HAMITES maxirous® 
TAB. LXII. — Fig. 1. 
Spec. Char. ^Slightly depressed; undulations even, 
rounding, disappearing at the back ; curvature 
gradual. 
Svn. Parkinson Org. Rem. III. Tab. 10. F. 4. 
As the curved part of a shell of this nature, cannot be 
increased by age, I conceive this to be a very large species. 
Except the size, I do not know any very strong character 
by which to distinguish it. 
This specimen is exceedingly handsome; the beautiful 
pearly shell covers a mixture of Pyrites and indurated 
marie, which serve to relieve it. Mr. Gibbs brought it 
with those of the last plate from near Folkstone.
