The following list of fossils from the Lower Chalk near Eastbourne 
is based upon collections made by the Rev. H. E. Maddock during 
his residence at that place, and on the examination of a collection 
from the Chloritic Marl made by Mr. IT. G. Fordham, of Odsey, 
Herts. Nearly all the species were identified by me, but most of 
the Sponges were seen and named by Dr. Hinde.
