Proceeding thence to Stoke Wood, crossing a ridge of 
Aymestry-limestone, the party stopped at a quarry of lower 
Ludlow, where some rare and interesting fossils have been 
procured, the rarest was the Acidaspis coronatus,? a tail of 
which was found by Mr. Brodie, with Holopella obsoleta 
and a pretty Bryozia. 
The Botanists ascended View Edge to search for plants, 
and obtained the very rare local plant, “ Astrantia Major,” 
the only locality, with one exception, where it is known to 
occur in England. Some time was spent in examining 
Stokesay Castle, a curious old building, which afforded 
much interest to the Archeologists. 
The next day the same party went by train to Church 
Stretton, and proceeded to the Longmynd to examine the 
oldest rocks of Shropshire, which consist of dark slates and 
grey schists, grits, and conglomerate. These Cambrian 
rocks were at one time considered to be unfossiliferous, but 
late researches have detected traces of Trilobites and worm 
tracks along the Ashes valley and in strata of the same age 
in Westmoreland. In Shropshire these bottom rocks are 
26,000 feet thick, as determined by the Geological survey. 
The walk was continued along the south western spur of the 
Longmynd, where, near little Stretton, a bed of Llandovery 
sandstone cropped out with Petraia and other usual fossils, 
in grits and conglomerates. A section on the Railway of 
Caradoc Sandstone, charged with the characteristic fossils 
was examined. Ascending the hill to Acton Seott, 
commanding a fine view of the adjacent hills, the well 
known quarry was searched for fossils but with little 
success,
