in lithic structure with that seen at the western end of 
Wainlode Cliff, but there is, however, this difference, that 
the Bone-bed at Denny Hill contains derived fragments of 
the subjacent “Tea-green Marls.” Now, at Wainlode ~ 
Cliff, the Bone-bed is separated from the “ Tea-green 
Marls” by 2 feet of black shale; whilst at Garden Cliff, 
the intervening deposit is 6 feet 5 inches in thickness. 
Upon referring to my section of Garden Cliff’, it will be 
noticed that a considerably ossiferous bed rests upon the 
“ Tea-green Marls” at that locality, and it may be suggested 
that the Bone-bed which occurs at Denny Hill upon the 
same deposits is its equivalent. I think not; and my 
reasons for doing so are as follows. Firstly, the section 
afforded at Denny Hill shows no “ Pud/astra-Sandstones,” 
and there is no evidence palzontologically that they are 
represented ; and secondly, assuming that what I have 
considered the true Bone-bed at Denny Hill is the equiva- 
lent of bed 15 at Garden Cliff, it will be seen that the 
Rheetic deposits above the Bone-bed at the two localities, 
when compared, much resemble each other—that is, as 
far as the Denny-Hill section allows. 
It is remarkable that the “ Pud/astra-Sandstones” of 
Garden Cliff have disappeared in so short a distance; and 
still more so since the maximum thickness of the deposits 
below the Bone-bed in North-west Gloucestershire is 
obtained at Chaxhill, and this latter section is only dis- 
tant about 2 miles from Denny Hill. 
Then what I have regarded as the equivalent of bed 13, 
is interesting on account of its ossiferous development : 
indeed, it is quite a “ Bone-bed.” It may be remarked, 
however, that bed 13 of the Crowle section in Worcester- 
shire, is also considerably ossiferous in places.* When I 
first examined the Denny-Hill section, I noted this bed as
