The Ironshot Bed next appears, and, as its name denotes, is full of the ferru- 
ginous granules. It has a thickness of three feet, and is the richest of 
all in fossils, which are collected with the shell on. It is here that the 
beautiful Pleurotomarise are found, with most of the Gasteropods. This 
bed passes insensibly into the 
Ammonite Bed, which is full of the characteristic Ammonites, Humphriesianus, 
Dundriensis, Braikenridgii, &c. It also contains a few of the Con- 
chifera. 
The Conchifera. Bed overlies the Ammonite bed, and is remarkable for the 
Dimyaria it contains. The limestone is different, being smooth and 
hard. It is 13 feet in thickness. In this are obtained Pholadomyas, 
Goniomyas, Isocardia, Myoconcha, Trigonia, Gervillia, and Pectens. 
These three beds correspond with the Humphriesianus zone of the Cottes- 
wolds. The two last zones, the Jurensis and Murchisoni zones, of the 
Cotteswolds, are not represented as distinct beds at Dundry. Their 
place would be under the Ironshot bed. The 
Ragstones come next, and contain the characteristic fossils of the Parkinsoni 
zone. They are loose marly limestones, having the same fossils as the 
Conchifera bed, but badly preserved, being only moulds or casts. In 
about the upper third of the Ragstone beds, is a Coral bed very rich in 
Isastrea, Stylina, Thecosmilia, and Axosmilia. It is also in the Ragstones 
that the beautiful and varied forms of Echini occur, of which 16 species 
have been collected. In these beds it was that Mr. Worsley found the 
Ammonites mentioned in his manuscript. Over the Ragstones lie 5 ft. 
of beautiful building stone, very soft, and resembling Portland stone. 
It may be seen very well in a quarry near the church. It contains very 
few fossils. Over this are found the 
Freestone Beds, which are fine beds of limestone, composed of comminuted 
shell-sand and debris of one kind or the other. It forms the cap of the 
whole, and attains an average thickness of 12 feet. It contains few 
fossils, but yields six species of Corals. When weathered the broken 
fossil contents shew out very distinctly.

the Dundry beds, viz, : —
