bed famous for its numerous and well preserved Star fish, 
Encrinites, Limulus, and other interesting and rare fossils. 
Perhaps in no Silurian locality have so many new and illustrative 
forms of life of the period been detected, and it appears by 
Mr. Marston’s careful section that certain layers are characterized 
by peculiar fossils, many of which, as the Asteride and Limulus, 
are not distributed indiscriminately throughout. After dinner at 
the village Inn, the party walked up Mocktree hill, where some 
extensive quarries afford fine sections of the Aymestry limestone, 
an argillaceous band of the Ludlow formation, usually separating 
the upper from the lower Ludlow, but owing to numerous faults, 
the section is not clearly defined, and Mr, Lightbody, of Ludlow, 
who accompanied the Field Club, seemed to doubt the regularity 
of the succession here, the strata being much confused and 
disturbed. The quarries at this spot have yielded some fine 
specimens of Phragmoceras and Lituites giganteus, but none 
were obtained on this occasion. The Club was much indebted 
to Mr. Lightbody for his effective guidance. On Thursday those 
who remained, visited again, for a more careful inspection, the 
banks of the Onney, searching the Wenlock shale and Caradoc 
sandstone, and obtained from the former some good tails of 
Asaphus longicaudatus, rarely found elsewhere, and seldom perfect, 
and some Trinuclei from the latter, and the rare Spheerospongia. 
The walk was continued to Horderley, where the Caradoc 
sandstone presents some instructive sections, being in places 
much disturbed, some layers abounding in organic remains : many 
fossils were found in the lowest strata near the spur of the 
Longmynd in grey shales, which afford Berychix, Trinuclei, and 
a new Proetus, a fine specimen of which was found by Mr. Brodie. 
It appears to be a rich bed and well worth a careful search. 
The strata here was much contorted, being affected, probably, 
by the upthrow of the Cambrian rocks of the Longmynd.
