Chapman records Lagena levis from the Hartwell Clay. One 
specimen, now in the Aylesbury Museum, is referred to L. clavata, 
which is probably a variety of LZ. levis. This, the only specimen 
found by the present writer, has a fusiform contour and a pointed 
base. JL. levis is one of the commonest of the Lagen, and has 
been recorded from the Woolhope beds (Brady). It occurs at the 
present day in all latitudes and at all depths down to 2,435 fathoms 
(Brady). JL. clavata has a similar distribution (Brady).
