154 REVISION OF THE GENUS NIPADITES. 
Species non satis nota.

Drupa basi major, superne deminuta, apice acuto; mesocarpio 
cum fibris densis longitudinalibus, crassioribus interspersis. 
The specimen figured by Bowerbank is nearly 24 inches long, 
and 14 inch broad near the base; it is much worn, and shows 
stronger longitudinal fibres with the intervening spaces filled 
with finer closely set ones with the same direction, but no trace of 
transverse fibrils. I can find no second specimen; and the one 
described is, in my opinion, too misshapen to form the type of a 
distinct species. 
Locality. Sheppey (London Clay).
