w horls about five, with their upper part rather flat, 
making the sides of the cone nearly straight; in the Fossil 
specimens the striae are often worn away. 
Bramerton Hill, near Norwich, affords these shells in 
plenty, and remarkably well preserved, sometimes even so 
as to vie with the recent ones in colour; there is some 
variety in shape, number of coloured stripes, &c. The 
upper figures are from a lengthened rather distorted spe- 
cimen, such as I have often seen recent; the others are the 
more usual form of the recent specimens, which are often 
larger and vary much, as nice discrimination will discover*
