laceous sandstone conglomerate. In this southern distriet 
we note a total absence of all organic remains. The whole 
ofthis series of rocks owe their origin to sedimentary de- 
posits: those, then, who are acquainted with the present 
formation of coral reefs in the Pacific ocean, will not be 
surprised at the limestone beds we meet with in the Quan- 
tocks, for we may describe the whole Quantock range as 
the bed of an ancient ocean, and the spots of limestone as 
being the coral reefs of that ancient sea, and the lasting 
monuments of the labours of those wonderful little 
zoophytic creatures, whose remains are plentiful in these 
spots, for many of these beds yield beautiful corals. We 
may remark that invariably we find the beds of coral lime- 
stones on the slope of the hill. I have met with favosites 
reticulata in the reddish limestone of Adscombe, Over- 
Stowey,and Doddington ; it is also found in the very dark 
indigo colored beds, as well as acervularia goldfussi, named 
by M. Milne Edwards, near the old mine at Doddington, 
and alveolites suborbieularis in the limestone beds of the 
same neighbourhood. The favosites polymorpha is a very 
prevailing coral at Over-Stowey, Asholt, and Doddington, 
as well as in the darker coloured beds of Blackhill and 
Higher Heatheombe. About one mile east of Buncombe 
Hill, Mr. Pring has discovered a small bed of limestone, 
altogether omitted from the Ordnance map, and which I 
have not yet seen. Specimens of favosites polymorpha were 
secured there, and its general character is much like the 
Cothelstone bed; only this latter has failed, as yet, to yield 
any organic remains. Encrinital impressions are common 
in the shales of all the beds. Generally the upper beds 
are of a dark indigo-coloured variety, then becoming, 
through various shades, a deep red. Near Ely Green 
‚Favosites appear, but no encrinital remains. At Over-
