VOL. XVI.(1) TOP-BEDS OF INFERIOR OOLITE Ti. 
Not one of the above three sections is as satisfactory 
as it might be as regards the upper portion of the “ Top- 
Beds,” neither do they appear to show such high beds as 
in the days of Witchell. Nevertheless, there is no doubt 
that in ascending order above the Upper Coral-Bed—or in 
its absence, where it would have occurred had it been 
present—come (3) brownish, somewhat unfossiliferous 
limestones, then (2) rubbly beds—teeming with Zeve- 
bratula globata along certain horizons, and containing an 
occasional specimen of Clyfeus Ploti—with, lastly, 
Witchell’s (1) White Limestone or Oolite. 
When the beds are followed to the south, the White 
Oolite becomes more distinct ; the underlying rubbly beds 
less easily separable from the subjacent less fossiliferous 
brown limestones, while the last two subdivisions become 
conjointly more massive. This succession is particularly 
well seen in a quarry near Horton Rectory, in the South 
Cotteswolds.
