NOTES ON THE POLYZOA AND MICROZOA OF THE RED CHALK OF 
YORKSHIRE AND NORFOLK. BY GEORGE ROBERT VINE. 
I. INTRODUCTORY. 
From the time when John Phillips, F.G.S. (1829), published his 
" Illustrations of tlie Geology of Yorkshire," up to the present, the 
origin and probable horizon of the Red Chalk, have been fairly dis- 
cussed by authors. It is only within the last thirty years, however, 
that the stratum has been worked out with any degree of skill, or 
that any attempt has been made to co-relate the Red Chalk beds, by 
means of their fossil contents, of Norfolk, Lincolnshire and York- 
shire. Then again, the differences of opinion which have been 
expressed by authors wlio have studied the pal£Eontological evidence, 
have helped to advance the importance and relative value of the 
fossil contents of this very peculiar band. It is not my intention, 
therefore, to comment on opinions raised by men who are far more 
competent to deal with the subject than I am, but a brief resume of 
what has been done will serve as a necessary preface to what will 
follow. 
In 1829, as regards Yorkshire, John Phillips gave a list of five 
fossils only, under the head line " Fossils of the Red Chalk," two of 
which were figured."^ As regards Hunstanton, Professor Sedgwick in 
1826t remarked in a foot note " that the red beds of Hunstanton 
Cliff contain the peculiar fossils of the gait in great 
abundance." 
In 1833, Mr. S. Woodward in An outline of the Geology of 
Norfolk,"^ gave a list of fossils of the Hunstanton Beds ; and 
Mr. C. B. Rose (1835), in a series of papers in the Philosophical 
Magazine, followed with remarks on the probable horizon of the Red 
Beds. As the history and hterature of this side of the subject have 
been given so admirably by Professor Seeley up to 1861, || and up to
