ON CRETACEOUS POLYZOA. 383 
With the exception of No. 4, not one of these species is cited by Morris 
in his Catalogue; and I shall have to deal with the forms independently. 
The horizons of these fossils as given by foreign authors are thefollowing :— 
1 Ceriopora polymorpha, Goldfuss.—EHssen Greensand. 
; { Ceriopora polymorpha, Mich.=Reptomulticava Arduennensis, 
d’Orb.—Gault, 
2. Echinopora Raulini, Mich. (d’Orb.).—Gault. 
3. Entalophora ramosissima, d’Orb.—Cenomanian. 
4. Radiopora bulbosa, d’Orb.—Cenomanian. 
5. Siphodictyum gracile, Lonsd. (local).—Neocomian. 
If we now take the lists of Lower Greensand Polyzoa given by 
Professor Morris and Mr. Etheridge in the catalogues already referred to, 
we shall find that the Faringdon species may be conveniently redistributed 
(if the identifications of these authors be correct) into the several 
Cretaceous horizons which will be found mentioned further on. It will 
then be seen that very little reliance can be placed on the Faringdon 
Polyzoa as typical Lower Greensand species, and I think Professor Jukes 
was justified in rejecting the evidence as being stratigraphically incorrect.
