looking as if made with the tail or body of the animal. 
A little distance to the east of the Wood House, 
in the centre of a small circular patch of cornstone, 
is a shallow quarry, in which Pteraspis Crouchii is 
most abundant, and I have also obtained several 
portions of Cephalaspis Lyellii. 
I hope that this brief guide to the fossil-bearing 
localities of the Old Red sandstone in this district may 
lead others to search for the relics of these ancient seas, 
as there is a wide field for discovery, many places in 
this neighbourhood having had but a very cursory 
examination by geologists.

There are several quarries of Aymestry limestone on 
the side of the road leading to Wigmore, where it passes 
through the wood. Those nearest to Ludlow belong to 
the upper members of this formation, and from them 
some very perfect specimens of the following fossils 
have been obtained : Orthoceras ibex , perelegans , subun- 
dulatum , virgatum , and gregarium, Bellerophon expansus , 
Discina rugata and striata , Eccidiomphalus Icevis, Mur- 
chisonia corallii , Cyclonema corallii , a new species of 
Natica , Pterinea retroflexa , and several others. 
About half way through the wood is a fine section of 
the Lower Aymestry limestone, and from it I procured 
one very beautiful specimen of the large Bellerophon 
dilatatus. Lingula Lewisii is here very abundant and 
perfect, often being found with both the valves entire. 
Tr achy derma squamosa occurs here in great numbers, 
and of a very large size ; also most of the usual forms. 
The Lower Ludlow rock is exposed in a fine section 
for some distance down the stream that flows at the 
bottom of Sunny Gutter, below Maryknoll. One of the
