As to the horizon at which these beds occur, all I can say 
at present is that they are above the Otley Shales, which are 
probably a portion of the Sabden Shales, and that they are below 
the Cay ton Gill Beds. 
My thanks are due to Dr. Wheelton Hind, Mr. Edgar D. 
Wellburn, and the Leeds University Botanical Staff for examining 
and naming the invertebrata, the fish remains, and the plant. 
Also to Professor Kendall for suggestions and assistance, and to 
Mr. Richard Chamberlain, the Resident Engineer, for permission 
to examine the material and for information as to dips.
