SILURIAN FOSSILS PROM LOCALITIES IN TORTWORTH. 
(d) The Horseshoe Farm area. 
All the Wenlock deposits hitherto described probably occur on very 
much the same general horizon. But the probability of the occurrence 
of higher, Ludlow, beds is suggested at one or more points in 
the district. At Horseshoe Farm, in the extreme southern part of 
the inlier, a considerable series of fossils was obtained from beds at 
a level, in fact, just below the Old Red. The following is the list, 
which is interesting, as in spite

Lord Ducie’s collection contains a considerable number of fossils 
from Horseshoe Farm. The following are preserved in yellowish or 
whitish sandstone : — 
Monticuliporoid 
Rhynchotreta cuneata 
Rhynchospira haylei 
Spirifer plicatellus 
Avicidopecten danhyi 
Pterinea retroflexa 
Phacops caudatus 
,, downing im 
Encrinurus punctatus 
Tentaculites anglicus 
Leptcena rhomboidalis and Rhynchonella Strickland^ which also have 
been found here, are preserved in limestone. The collection from this 
locality also includes Atrypa reticularis and Spirifer crispus. The 
occurrence of Aviculopecten danhyi is very suggestive of Ludlow. 
The discussion of the palseontological features of these faunas as a 
whole, with their special bearing on the stratigraphical problems of the 
district, will be found in our paper in the Quarterly Journal of the 
Geolog iced. Society.
