VOL. XVI. (2) INFERIOR-OOLITE ECHINOIDS 189 
In the dissection and re-grouping of Munier-Chalmas’ 
details I have had the invaluable assistance of Mr S. 
S. Buckman. Mr Buckman has already referred to this 
author’s work, and effected a certain amount of correlation." 
Concerning the upper beds he has written: “There can 
be no doubt that No. 6 of Munier-Chalmas equals the 
Truellec hemera; but in No. 7 there is shown apparently 
a division not yet attempted in this country. In No. 8, 
‘calcaires 4 Pervisphenctes zigzag, there is no difficulty in 
recognizing the fauna of the zzgzag hemera.” 
From the adapted record given above, it will be 
observed that Stomechznus begranularis occurs on about 
the same horizon as the Azadacza-Limestones and Rubbly- 
Beds, and at a short distance above the base of the 
“White Oolite.” Other fossils may be consulted to 
complete the correlation. The ammonites show that the 
bottom-portion of the “ White Oolite” is of 77wellec 
hemera, and therefore roughly comparable with the 
Doulting Stone, and possibly also with the Upper Coral- 
Bed; while the next bed below the White Oolite is 
the Cadomztes-linguzferus-Bed. It is very interesting to 
be able to recérd that a fragment of an ammonite obtained 
from the very thin coralliferous horizon at Tog Hill was 
_ tentatively identified with this species by Mr Buckman 
some time before the date of the Upper Coral-Bed had 
been discovered or even suspected. 
As regards the beds above, Belemnites (Belemmnopszs) 
Bessinus, @Orb., is not uncommon in the Fullers’ Earth 
of Doulting, where it is closely associated with Ostrea 
Knorrz. The basement-bed of the Fullers’ Earth at 
Doulting appears to be somewhat vemanzé, and the frag- 
ments of belemnites may be mostly from it, and have been 
mainly derived from an inter-77wedlez-zigzag deposit. But 
in the same bed was a fragment of an ammonite “ possibly
