furnished a short description of the same.’ In_ his 
“ Geology of Oxford,” Prof. J. Phillips published a section 
he had recorded in company with Mr J. E. Lee,’ which 
closely approximates with that given in the present com- 
munication. In 1873, the Sheet of Vertical Sections 
containing that at Garden Cliff, was published by the 
Geological Survey, the authors being Messrs Bristow and 
Etheridge.’ This reading differs in but a few minor details 
from that previously communicated by the latter author. 
The Geologists’ Association visited the locality in 1875 
under the guidance of W. C. Lucy; the section given in his 
report being similar to those previously published.* In 1878 
Dr Wright® reproduced the section he had noted about 
the year 1860, and also that by Mr Etheridge. On July 6th, 
1888, a general description of the section was given by 
Mr W. F. Gwinnell, previous to a visit of the Geologists’ 
Association in the August of that year, and is apparently 
based upon Mr Etheridge’s papers.®° The “ White Lias” 
is stated to be 15 feet thick; the Rhztic Shales or “Zone 
of Avicula contorta,’ 17 feet. The grey marls (No. 4 in 
my section), are shown to commence the Upper Rhetic: 
this appellation and the term “White Lias” being used 
synonymously.’ 
In Mr H. B. Woodward’s “Geology of England and 
Wales,” reference is made to the section as “one of the most 
famous exposures of the Rhetic Beds,”* whilst Etheridge, 
in 1865, remarked that he believed the term “ Penarth 
Beds” was adopted by the Geological Survey as a British 
equivalent of the European term Rhetic beds, mainly
