NAUTILUS inequalis. 
TAB. XL .* — Lower figures . 
Spec. Char. Spheroidal umbilicate; aperture 
nearly round ; septa distant in the inner whorls, 
and approaching near together in the outer 
whorls; siphunculus near the inner margin of 
the septum. 
The aperture is obscurely three-lobed from its partly em- 
bracing the volution : it is about half the diameter of the shell 
long, and the same in width. It is remarkable for the septa 
being more distant as they approach the interior or first 
formed whorls, where their distance from each other is 
equal to their own length. The septa are but slightly 
curved. 
The specimen is from Folkstone, by favour of Mr, Gibbs;; 
its chambers are filled with an Irony clay, the remains of 
the shell being Carbonate of Lime.,
