have been described and partly figured by A. Meunier and Ed. 
Pergens." The probable horizon of the Calcaire grossier rocks are 
on a line with our Bracklesham beds according to Lyell, but are 
characterised as " Eocene inferieur" by the authors. The number of 
fragments on which (observations and identifications were based 
amounted to between 500 and 600, out of which about 31 species 
were identified, but only 24 are described. The others are reserved 
for further identification. 
The list will be valuable to students of the Polyzoa fauna of our 
Eocene Rocks. Besides tlie Polyzoa there were a fine series of Ostra- 
codaand Foramnifera, and although Polyzoa are rare, comparatively, 
in the Bracklesham beds, Ostracoda and Foramnifera abound in the 
finer debris of the clay, but I cannot say to what extent. Foram- 
nifera (about 60 species) are abundant as individuals in the London 
Clay of Sheppey.
