40 GASTEROPODA OF THE INFERIOR OOLITE. 
northwards, this is the next exposure met with. It is a small quarry three miles 
south-west of Crewkerne Station. There is about six feet of stone in three blocks. 
The whole is probably in the Murchisone-zone, if not lower. Waldheimia anglica 
is very abundant, and the place is remarkable for very pretty species of Trochus or 
Delphinula. This is the most western point of any of the quarries noted. 
Hasurpury (see Profile No. 3, p. 41).—One and three quarter miles north-east 
of Crewkerne Station. This is a place of considerable importance as a quarry, but 
it is more remarkable for Hehini and Conchifera than for Gasteropoda. Isocardia 
cordata is a noteworthy fossil here, since its occurrence in Dorsetshire has not 
often come under my notice. 
It must be allowed that Profile No. 3 is very inferior in interest, for our 
purpose, to the two preceding, since but few Gasteropoda are noted from this 
quarry. I have introduced it mainly to show the preponderating importance of 
the Lower Division, and especially of the MJurchisone-zone in this area. The 
‘massive shell-bed with keeled Ammonites”’ certainly represents nothing higher 
than the concavus- (Sowerbyi-) zone, whilst all the rest must be in the Murchisone- 
zone or lower. ‘The Gasteropoda are probably on the same line as at Drympton, 
which I conceive to be towards the base of the Murchisone-zone. 
Résumé of the south-western half of the Dorset-Somerset District. 
On the coast and for some miles inland the Lower Division of the Inferior 
Oolite is only feebly represented as a limestone, and, although there is an 
interesting shell-bed, associated with a line of irony nodules, which may be traced 
for some miles, containing the fossils of the Murchisone-zone, yet the development 
and also the fossils of the Upper Division, and notably of the Parkinsoni-zone, 
greatly preponderate. Near Beaminster, and north of that town as far as Hasel- 
bury, the very reverse of this state of things obtains. With the single exception 
of the quarry at Broadwinsor all the fossiliferous exposures known to me are in 
the Lower Division, and for the most part low down in that division, which is 
thicker than towards the coast. 
It now remains to consider the north-eastern half of the Dorset-Somerset Dis- 
trict, and we commence our researches in the vicinity of Yeovil Junction. 
Kast Coxer.—Two and three quarter miles south-west of Yeovil Junction. I 
have not been here myself, but am informed that there is only about three feet of 
limestone. The fossils are those of the Murchisone-zone, and especially Cirrus. 
Srororp.—The limestone quarry is a few hundred yards west of Yeovil Junc- 
tion. The Inferior Oolite Limestone is only a few feet thick, but affords a very 
complete section, which may be traced to the base of the Fuller’s Earth. Itis more
