Tuts differs from the recent species (P. Aldrovandi) in 
being less obliquely truncated at the anterior side, in 
being more regularly cylindrical, and in being thinner. 
A sandy mass of indurated marl replete with fragments 
of shells apparently from the London Clay formation 
found lying upon the coast near Lowestoft in Suffolk, by 
Dawson Turner, Esq., contained several fragments of 
this celebrated shell. Figs. 1. & 2. represent two of 
these fragments. 
The Crag near Ipswich also contains fragments of the 
Panopea Faujas, as well as of P. (Mya) intermedia. 
Figs. 5. & 5. are of the first species ; in one of thema 
large pearl has been formed. Fig. 4. is probably a portion 
of the intermedia. 
Panopza Faujas is one of the Italian shells that has 
by several authors been considered as identical with the 
recent species in the surrounding sea; but although 
they are nearly alike, there are distinctions that cannot 
be mistaken when once pointed out. 
Since the above went to press we have seen one entire 
valve and a considerable portion of another valve of a 
small Panopeza that appears to be different from P. Fau- 
jas: they were found in Crag, by S. V. Wood, Esq.
