A little further to the north the beds below this are more dev eloped 
and are seen resting upon the red marl.” 
In 1845', the same author gave a slightly different read- 
ing, of which the chief points to notice are: (1) The 
thickness of the “‘ Insect-limestone,” which is stated to be 
2 feet thick, and separated by 1 foot of shale from the 
“ Cypris-bed,” and (2) that this latter bed is separated 
from the Bone-bed by only Io feet of deposit. In accord- 
ance with the object of his work, especial reference is 
made to the “Insect-limestone,” or Psezdomonotzs-bed, 
which “contains numerous elytra of Coleoptera, and small 
plants resembling seeds. These lie in the centre of the 
- slabs of limestone, intermingled with the shells.”* 
In his essay “On the Formation of the Rocks of South 
Wales and South Western England,” Sir H. De la Beche 
gave a useful section recording 6 feet of deposit between 
the Pseudomonotis- and Fstheria-beds—the latter is No. 5 
in his section?. 
Some general remarks upon the section were made by 
Brodie in 1858.4 
Sir W. V. Guise in his Presidential Address to this Club 
in 1860,> gave a section recorded by J. Jones and 
W. C. Lucy, on account of its differing so materially from 
1 “A History of the Fossil Insects in the Secondary Rocks of England ” (1845), 
pp; 79, 80. The ihre eed to the “ Insect-limestone ” includes that of the shales 
above. 2 Ibid. p. 8
