representative of both Lower and Upper Gault, formed outside of the 
limits of the area reached by mud-bearing currents." 
In his conchiding remarks in the " address" already referred to, 
Mr. Whitaker says, " From the evidence before us it seems to me 
that our Red Chalk is probably one of two things ; either it is a part 
of the Lower Chalk or else it is a representative of that and of the 
upper part of the Gault. It is certainly chalk to some extent. 
Consequently, were I obliged to confess my belief in any one forma- 
tion, I should simply say that Red Chalk is — Red Chalk." (p. 284, 
op. cit.) 
II. Description of the Polyzoa. 
In the two papers published in the Proceedings of this Society''' 
I have described as fully as was possible the Polyzoa of the Cam- 
bridge Greensand. In presenting another paper on the Polyzoa of 
the Red Chalk of Hunstanton, it is only fair to state that a 
Monograph of the Polyzoa of the Red Chalk has already been 
published in the Journal of the Geological Society, f As, however, 
,so many of my papers on Polyzoa have been read before the members 
of this Society and published in their Proceedings, one perfectly 
distinct from the other on the Red Chalk may not be deemed out 
of place. In the Monograph referred to only the new species that 
are described are figured, but though I have adopted D'Orbigny's 
names for some of the uniserial Stomatoporse, the figures of the 
British examples may be produced with advantage to illustrate the 
present paper, but there will not be any need to re-describe the 
species except when additions or alterations are made.
