3. LuDulites urceolata ? Lamk., Tab. i , fig. 8, and 
4. Idmonea coroiiopus Defrance, Tab. ix., fig. 24, p. 153. 
As these will be referred to again further on it will be useless to 
make remarks on the species. 
In Morris' catalognie of British Fossils (1854), and also in the 
Pala)ontological part of Jukes's " Student's Manual of (jeology" 
(1857), the following species and their horizon arc indicated : — 
1. Flustra crassa, Desm. London Clay: Prinn'ose Hill. 
2. Eschara Brongniarti, Lonsd. ; Bracklesham Bay. 
8. Cellepora petiohis, Lonsd. Mid-Eocene, Bracklesham. 
4. Jjunulites urceolatus, Lamk. Coscinopor'm p'deolii^, Phill. and 
Wood, Mid-Eocene, Bracklesham. 
5. Idmonea coronopus, Defr. Mid-Eocene, Bracklesham Ba3\ 
In 1866 Mr. Ueorge Busk, F.K.S., published in the Geological 
Magazine (Vol. iii., p.p. 298-302), a description of " Three species of 
Polyzoa from the London ('lay at Highgate, in the collection of W. T. 
Wetherell, Esq., F.G.S." The plate containing the figures were 
drawn, but never published, by J. De Carle-Sowerby, and this, with 
the figures of Lonsdale in Dixon's Geology of Sussex, are the onl}^ 
illustrations of British Eocene Polyzoa that I am acquainted with. 
As regards the literature three other references will complete the 
list also. 
In Phillip's work on the Geology of Oxford and Valley of the 
Thames (ed. 1871), I find the following reference. After giving a 
rather full list of Polyzoa, ranging throughout the whole of the 
Cretacious epoch (pp. 434-436), the author refers briefly to the 
Eocene strata within the drainage of the Thames, and Polyzoa are 
mentioned, but genera only, no species are given.

In the " Catalogue of Tertiary Fossils" in the School of Mines 
(1878), I find references to the following species only : — 
Flustra crassa, Desm. Thanet Sands, p. 7.
