ANOMIA. 27 
Affinities —This species is distinguished by the convexity and triangular form 
of the valves, and by the broad and deep lunule. NV. apiculata, Sowerby, was 
regarded by the late Rev. W. Downes as a synonym of N. antiquata (see p. 24). 
Types.—In the British Museum. The specimens figured by Gardner (except 
fi. 6, which is in the Downes Collection) are in the Bristol Museum. 
Distribution.— Blackdown Greensand (zones vii to x).

Remarks.—A species of Nucula is represented in the Montagu Smith Collection 
(Woodwardian Museum, Cambridge) by eleven specimens ; it approaches closely 
in form d’Orbigny’s N. Renauviana’ found in the Turonian of Uchaux, but 
unfortunately all the specimens are internal casts, so that an exact determination 
is impossible.
