apex obtuse; base, but not the columella, rather obliquely 
truncated ; columella taper, gently curved inwards ; 
right lip entire, above, pressed against the preceding 
whorl and wholly concealing the spire, the apex of which 
appears a mere hollow point; the length is rather more 
than three times the greatest width. 
An extremely fragile, but by no means uncommon, 
shell, in the clay upon the Hampshire coast and in the 
neighbourhood of Paris. At Grignon it is found much 
larger than my figures, but rarely. The largest English 
specimen I have seen enriches the cabinet of Miss Dent ; 
the next in size that of Lady Burgoine ; two collections 
which have become very serviceable towards compleating 
a knowledge of Hampshire fossils. 
I have followed the French authors in quoting both 
of Brander’s figures, although I suspect he had the 
two shells given in this and the following plate ; but I 
believe we have no means left now of determining this 
point, or which is which, if he had both.
