Spec. Char. Ovate acuminated ; surface di- 
vided into square cells by many acute 
sutures that decussate 8 or 10 prominent 
carinse ; whorls ventricose, flattened above ; 
aperture oval, the outer lip toothed within. 
The length is at least double the width; the upper- 
most Carina is largest; the principal ones below it, al- 
ternately large and small, with still smaller ones between 
them ; they are all rounded. The beak is a little curved, 
arid contains an open umbilicus. 
Found in the Crag of Suffolk and Norfolk by Mrs.

1:1 et ween the elevated edges of the sutures, the surface 
is smooth, but divided by many (12 or more upon the 
last whorl) transverse, rounded, alternately large and 
small elevations or keels, that do not by their various 
sizes destroy the round contour of the whorls ; the outer 
lip is thickened internally, where it has many elongated, 
lamellar teeth ; the inner lip is, when fully formed, re- 
lieved from the columella, and has one or two irregular 
plaits upon its upper part ; the beak is rather short, 
A species sent among others from Hordwell ; its 
sutures are not generally varicose, the smoothness of the 
surface between them, gives it a neat appearance.
