The Cotteswold sands are not exposed except in some of the 
lanes on the King Stanley side of the hill and the adjacent Pen 
wood, but there is a small Section of the Cephalopoda bed in 
the wood, at an elevation of about 550 feet, which will give 
about 150 feet for the thickness of the sands. This agrees 
with the estimated thickness at Frocester hill. The Cephalopoda 
bed is about four feet thick, and contains the common Ammo- 
nites found at Frocester hill, but they are not so well preserved. 
T obtained a single example of A. serrodens, Quen., one of the 
rare species at Frocester hill. Lycett found one specimen, but 
it appears to have escaped the notice of Dr Wright, and is not 
described in his monograph of the Lias Ammonites. 
The beds of the Inferior Oolite are all more or less exposed 
in one or other of the quarries on the slope or on the top of the 
hill, but the lower part of the building Freestone has not 
been quarried. The quarries on the northern slope and the 
escarpment above are six in number, and, for convenience of 
reference, I have numbered them in descending order. No. 1 
is the Ragstone quarry, on the top of the hill, near the tumulus ; 
No. 2 is a little below, but almost adjoining; No. 3 is close to 
the enclosed land, and 150 yards down the slope ; Nos. 4,5 and 6 
are a short distance above Selsley Church, and are very near 
together, No. 4 being on the north side, No. 5 adjoins it; this 
quarry has been worked farther into the hill than the others; 
No. 6 is south of No. 5, it may be called the limekiln quarry, 
as there is a limekiln in it. The whole are on the north angle 
of the hill above Dudbridge. 
Above the sands are the basement beds of the Inferior 
Oolite, commencing with the brown sandy Limestone beds, 
usually about seven feet thick, but only partially exposed at 
Selsley. In recently working these beds at Haresfield hill with 
my friend Mr S. S. Buckman, F.G.S., we found that about a 
foot of the lower part of the bottom bed contained Ammonites 
opalinus in abundance, associated with the usual conchifera of 
the Cephalopoda bed beneath. 
Above the Sandy Limestone beds the Lower Limestone pre- 
sents nearly the same uniformity in character as in other
