The whorls are in number about three, quickly diminish- 
ing*, the aperture being half the diameter of the shell long 
at the back, one fourth wide; the front narrower. The 
long radii are very prominent near the centre of the 
shell, and obscure towards the middle of the whorls ; near 
the front they are again prominent, and together with the 
short ones form the crenulated margin; they all curve a 
little towards the mouth. The middle of the front is nearly 
plane. The cast is ornamented in the same way as the 
external surface. 
This beautiful species is found in a pyritaceous marie at 
Folkstone in Kent. I received specimens from Mr. Dill® 
wyn, and also from the indefatigable Mr. Gibbs. I do 
not yet know of their being found elsewhere, although some 
other of the Folkstone species are found in Sussex. The 
shell often remains: it is extremely thin, and of a cream 
colour, except where it has become partly decomposed^ 
when it often exhibits the most splendent iridescent lustre^ 
equal to those Ammonites, &c. envelioped in the Carinthka
