FULLONIAN: FROME. 239 
Whatley, we find the Fuller's Earth Rock, yielding Goniomya, 
Pholadomya. Pinna, Rhynchonella varians, &e. ; and the same 
rock, consisting of pale grey earthy and shelly limestone, inter- 
stratified with grey and brown " racy " clays, may be seen between 
Murdercombe and Egford Bridges, to the west of Frome. 
As before mentioned, there does not appear to be any con- 
siderable thickness of clay between the Inferior Oolite and the 
Fuller's Earth Rock in the neighbourhood of Frome. At the 
same time the Fuller's Earth Rock itself may be developed at 
somewhat different horizons in the central portion of the series, 
and in this neighbourhood the stone-beds do not occur in so thick 
a form as at Shepton Montague and Sherborne. 
The beds near Frome were well exposed in a cutting on the 
eastern side of the stream at Egford Bridges. Here they com- 
prised about 10 feet of pale earthy and hard shelly limestones 
and marl, appearing in rubbly and irregular beds. Fossils were 
very abundant ; and from this section, and others exposed at 
the Sewage-works north of Frome, I obtained the following 
species : 
Ammonites. 
Pleurotomaria. 
Anatina plicatella. 
Astarte rotunda. 
Card him (cast). 
Ceromya plicata. 
Cypricardia bathonica (cast). 
Cyprina (cast). 
G-erviliia. 
Goniomya literata. 
Gresslya peregrina. 
Isocardia minima. 
nitida. 
Lima duplicata. 
Lucina. 
Modiola gibbosa. 
sowerbyana. 
Myacites tenuistriatus. 
Nucula. 
Ostrea subrngulosa. 
Pholadomya deltoidea (abun- 
dant). 
Trigonia (cast). 
Ehynchonella varians (abun- 
dant). 
Terebratula globata (abundant). 
maxillata. 
Waldneimia bullata. 
ornithocephala (abundant). 
Serpula tricarinata. 
The following section was seen in a disused quarry, south-west 
of Bonnyleigh Hill, between Frome and Beckington :

The total thickness of the Fullonian series at this locality 
cannot be much more than 35 feet, as the shelly oolitic limestones 
of the Forest Marble appear in the scarp above this quarry : 
whereas at the boring for coal at Buckland Denham, about 3 miles 
to the west, the formation must be upwards of 100 feet thick. 
From this it seems possible that the Forest Marble overlaps some 
of the higher beds of Fuller's Earth, and such would also appear 
to be the case between Nunney and West Cranmore : but further 
evidence is needed on this point. (See Fig. 38, p. 91.)
