THE CRETACEOUS ROCKS OF BRITAIN. 
Of the Cliloritic Marl here Mr. Strahan remarks that it 
contains “ rolled brown phosphatic casts of fossils in a matrix of 
chalky glauconitic marl. At its base the phosphates are especially 
abundant, and are mixed with vivid green rolled fragments of 
grit and many dark green or black grains. The surface of the 
grit below is vivid green, and has been eroded into holes in which 
the marl rests.” 
I observed similar relations between the base of the chalk and 
the top of the Selbornian in a pit on Chilcombe Hill still further 
west; here also pebbles of the grit occurred in the glauconitic 
chalk, but there were few phosphatic nodules. 
The following lists of fossils, obtained from the different parts 
of the Lower Chalk at the localities above described, have been drawn 
up from several sources, (1) from collections made for the Survey 
bv Mr. J. Rhodes, (2) from the lists published by Mr. Fordham 
and Prof. Barrois, (3) from a list kindly communicated by Mr. C. 
J. A. Meyer of fossils collected by him from the basement bed at 
White Nore. 
The letters indicate the localities at which the species have been found 
thus : — 
b=Ballard cliff. m=Mupe Bay. 
c=Pits near Corfe. 1=Lulworth Cove. 
w=Worbarrow Bay. r^Ringstead and White Nore. 
x=Chaldon (from Museum Catalogue of Cretaceous Fossils and from 
Barrois’ Recherches.)
