resemble the Corallian iron -ore of Abbotsbury. South of 
Symondsbury these beds were also exposed to a depth of 12 feet, 
and there they contain concretionary ironstone. Their extent here 
may be too limited to render them of economic importance us an 
iron-ore, even if they be considered rich enough for smelting. 
(See analysis, p. 498.) From these beds I obtained the following 
fossils : 
Ammonites corrugatus. 
Murchisonas. 
Thraoia lata. 
Trigonia. 
Belemnites Blainvillei. Unicardium. 
Astarte excavata. Khynchonella angulata ?. 
Myacites tenuistriatus. 
Ostrea. 
Terebratula. 
Below these iron-shot beds, there were hard brown sandy and 
occasionally iron-shot limestones, 2 to 3 feet thick; and, nt the 
base, yellow sands with bands of hard and nodular bluish-grey 
sandy limestone. At this locality Mr. S. S. Buckman records 
A. MurchisoncB and A. opalinus from the same bed.* In the 
Museum of Practical Geology there is a specimen of Eryma 
from Chideock. 
The sands were also exposed on the eastern side of the northern 
Chideock Hill, and from these I obtained Ammonites (fine var. 
near to concavus), Belemnites, Pecten l&viradiatus, Rhynchonella 
jurensis "?. Dr. Wright records from the sands at Chideock, 
Ammonites insignis, A. opalinus, and A. variubilis. 
Wide fissures or " caverns " were noticed in the Inferior Oolite 
of Chideock Hill by Buckland and De la Beche.f 
The iron-shot beds of the Inferior Oolite have been quarried 
at Watton Hill, north of Bridport ; the higher beds have been 
worked at another Watton Hill, near Lower Loders, and at 
Powerstock. The fossils obtained from these localities are 
mentioned in the accompanying list. As a rule the iron-shot beds 
are more fossiliferous than the pale limestones above. 
The railway-cutting east of Lower Loders exhibited a fine 
section of the Inferior Oolite ; it was as follows :
