suffered much from atmospheric influences, and it is 
necessary to excavate rather deeply before good examples 
of the organic contents can be procured. From bed 15 of 
the present record Mr Harrison obtained Avzcula contorta ; 
while of bed 13 the same author wrote, “in this no fossils 
were detected.” The investigations of the present writer, 
however, yielded better results, and were such as might 
be expected, judging by the equivalent deposit at Crowle. 
Bed 14 yielded to Mr Harrison Avecula contorta and 
Protocardium rheticum. At four feet above bed 14 
Mr Harrison noticed a limestone-nodule, which he de- 
scribed as “an oval mass of limestone 2% feet long by 10 
inches in thickness. It was apparently zz sz¢w, for the 
shales wrapped round it in an undisturbed manner. This 
is rather a low horizon for the presence of septaria, but at 
Leicester bands of similar nodules occur in precisely the 
same position resting upon the shales.” Now if the 
reader refers to pages 146 and 147 of Volume XIV. of the 
“Proceedings,” he will notice that in the section of Coomb 
Hill, given on page 146, certain nodules, together with 
the one or two layers of hard shelly limestone upon 
which they rest, were considered the equivalents of beds 
5b to 7. Inthe Norton section the nodules and subjacent 
limestone were given as equivalent to bed 7, since there 
were present in that section beds equivalent to 5 b and 6. 
As will be gathered from the text on page 147, however, 
some uncertainty existed as to what bed the nodules at 
Coomb Hill represented. From the evidence available in 
Worcestershire the writer is inclined to think that he was 
correct in his correlation of the nodules and the subjacent 
limestone of the Norton section with bed 7 ; but those beds 
numbered 7 to 5 b at Coomb Hill must be described as bed 
7—beds 5 b and 6 being absent. Thus he would consider 
the nodules of Mr Harrison’s section bed 7 ; and the lime- 
stone bed two feet above, 5b. At Woodnorton again we have
