NA.UTILOIDEA. 
Glocker’s figures of this species, though representing a crushed 
and distorted fragment, show very clearly the characteristic zigzag 
ornaments of the test. 
D’Orbigny must surely have overlooked Fitton’s excellent figure 
in the ‘ Transactions ^ of the Geological Society {V)c. cit.), or he could 
not have failed to recognize the identity of Fitton’s species with 
his own — N. Requienianus — which now falls into the synonymy of 
N. plicatus. 
The largest example of the present species in the British Museum 
(No. 44463) measures about 1 foot in its greatest diameter and 
about 10 inches in its greatest width. 
Horizon. Lower Greensand. 
Locality. Atberfield, Isle of "Wight.
