DORSET-SOMERSET DISTRICT. 39 
P,, or the Brachiopoda-bed, the upper portion of which is a complete arabesque or 
shell-entablature ; large specimens of Trigonia costata and other Trigonie occur. 
Brachiopoda are very numerous; hynchonella spinosa, Waldheimia carinata, Tere- 
bratula Phillipsti, and a few T. spheroidalis in the lower part. Several Gastero- 
poda were obtained from this bed in 1885. Ps, the upper shell-bed just under the 
Fuller’s Earth, is nearly two feet thick, and contains one or two peculiar Gastero- 
poda, and notably the only species of Brachytrema I have succeeded in discovering 
from the Inferior Oolite of the Dorset district. 
Loprrs.—An old quarry face at Upper Loders displays pretty much the same 
sequence as at Vitney Cross. At all events the Astarte-bed, P,, is the main 
source of the Gasteropoda which come from here, as is the case almost everywhere 
east of Bridport. The irony nodule-bed with the Murchisone-like Ammonite 
just below is in its place about two feet underneath, then grey calciferous grits 
and brown sand-rock, showing the lithology of the opalinus-zone, though apparently 
without its fossils. 
Beaminster.—This town is five and a half miles due north of Bridport. I do not 
know of any quarries in the town, but there are some in the neighbourhood. 
There are a few Gasteropoda marked “ Beaminster” in the Buckman collection ; 
and some have been sent to me from Mapperton, a village not far off. Judging 
from appearances, this is a neighbourhood where the Parkinsoni-zone has lost its 
predominance, and where such Gasteropoda as have been collected may be safely 
assumed to belong to the Lower Division, though to what stage of the Lower 
Division may not in allcases be clear. There is a quarry at Horn Park, one anda 
half miles north-west of Beaminster, showing nine feet six inches of limestone. 
The Lower Division here is five feet thick, and very full of Cephalopoda. The 
upper four feet six inches of this quarry consists of yellowish Oolite poor in fossils, 
which probably belongs to the Upper Division, though its rich shell-beds have dis- 
appeared. All this favours the supposition that “‘ Beaminster” specimens may be 
set down either to the concavus- (Sowerbyi-) zone or to the Murchisone-zone. There 
is an exposure likewise at a place called Wadden Hill (marked Stoke Knap in the 
map) not far from Horn Park, where the opalinus-zone appears to be fossiliferous, 
since I have a specimen of the Am. torulosus from here, and two or three 
indifferent Gasteropoda. 
Broapwinsor.—Three and a half miles north-west of Beaminster. This has 
been an important quarry for many years. The face of stone is about eight feet 
four inches thick, and presents no very definite shell-bed. There is abundance of 
T. Phillipsii in the upper beds, and of 7. spheroidalis lower down. The whole is 
in the Upper Division and probably in the Parkinsoni-zone, thus forming a marked 
exception to all other quarries in this neighbourhood. 
Drympron, one and three quarter miles north of Broadwinsor.—Going still
