which Sharpe states to be from the “ Grey Chalk.” We have there¬ 
fore inserted this and others from Mantell’s list under the zone of 
Hoi. subglohosus, and have distinguished them by s. (Mant.) if from 
Southerham, or bv the locality in full. 
The letters in the list stand for the localities, thus— 
h=Hamsey. 1=Cuttings north of Lewes. 
m=Middleham. n—Newtimber. 
r=Ringmer. s== Southerham. 
c=Clayton g=Glynde. 
Those from the first three are solely on Dr. Mantell’s authority, 
and we have entered them all as coming from the zone of Ammo¬ 
nites varians, as from the position of the places, and from his calling 
the rock “ Chalk Marl,” it seems probable that they came from 
that zone.
