APPENDIX II. — COMPARISON OF THE UPPER TOARCIAN BEDS IN 
YORKSHIRE AND THE COTTESWOLD HILLS. 
BY S. S. BUCKMAN, F.G.S. 
The Yorkshire deposits of striatuli and ])Oiit-striatuli date 
(Yeovihan) are thick, and as the}^ sheA\- considerable Hthic differ- 
ence they have received individual stratigraphical names. 
The Cotteswold deposits of the same date on the other hand are 
thin, and have little lithic difference. They have in the main 
received no distinguishing stratigraphical names ; but have been 
lumped together and called the " Cephalopod Bed," a faunal 
term, and only lately has it been subdivided and the subdi\dsions 
called by ammonite names — also faunal terms. 
Now stratigraphical or lithological terms are a great con- 
venience ; and it will facilitate comparison to coin a few for the 
Cotteswold rocks. With terms already in use we should then have 
this series : —

Lithic details var}^ ; but this fairly represents what may be 
found just south of Stroud. 
The Yorkshire strata to be compared are already named. 
There are : — 
Dogger 
Yellow Beds 
^ , f Serpula-Heds 
Grey Beds \Lingula-Beds 
Striatulus - Shales . 
The series of Ammonites submitted b}^ Mr. Richardson, 
collected partly by him and partly by Mr. S. H. Herries, with what 
have been examined on other occasions, give sufficient informa-
