298 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Apr. 5, 
lock shales near Caer Caradoc. I infer, consequently, that the Cara- 
docs skirting this part of the Longmynds are the uppermost — 
and that the lower beds are deficient. 
2. Conglomerate near the Longmynds at Little Stretton, resting 
at a low angle on highly inclined flags. The fossils in this conglo- 
merate are Pentamerus levis, abundant, Spirifer radiatus, and some 
badly-preserved brachiopods and corals (Favosites, Turbinolopsis 
bina). 'These are probably upper beds of the Caradoc resting on 
Liandeilo flags. 
3. Caradoc limestone quarries, at Esquire Hall, near Bishop’s 
Castle. Brown sandstones and sandy bluish limestone bands. 
The fossils most abundant im this locality are the Pentamerus 
levis in the limestone bands, and Atrypa reticularis, var. orbieularis, 
in the sandstone. Other species are— 
Atrypa hemispherica. Orthis calligramma. 
Lepteena sericea: Actoniz. 
Orthis expansa. Spirifer radiatus. 
elegantula. Terebratula imbricata. 
Of univalves three species, including Littorina striatella : of Trilo- 
bites, Cybele punctata: of Corals, &c., Favosites alveolaris?, Tenta- 
culites annulatus. 
This locality shows the connection between the sandstone beds and 
limestone, and therefore indicates the sequence in time of the former 
with the Wenlock beds above the latter. 
4. The compact quartzy sandstone of the Bogmines: a small out- 
lier resting unconformably on the Llandeilo flags, and resembling in 
mineral aspect the Stiper rock, which is a member of the latter. 
Very fossiliferous and nearly horizontal. 
[Brachiopoda.| The most abundant species are Leptena depressa 
and Atrypa reticularis var. aspera; Terebratula imbricata, furcata, 
decemplicata, and 5 other species; Orthis elegantula and 3 other 
species ; Chonetes sarcinulata’, Pentamerus levis’? 
[Lamellibranchiata], 2 species. 
[Univalves], 12 species, including Turritella cancellata and Bel- 
lerophon Wenlockiensis. 
[Annelida], 3 species; Tentaculites annulatus and scalaris, and 
Cornulites serpularius. | . 
[Trilobites], Z7:nucleus Caractaci, Calymene Blumenbachii, plen- 
tiful ; 2 species of Cybele and 2 other Trilobites; 2 Corals. 
This rich list of 45 species was noted in a single small quarry 
in less than an hour. It indicates a relation to both Caradoc and 
Wenlock, with local peculiarities besides. The beds are doubtless 
the upper beds of the Caradoc, accumulated near to land or to a 
great elevated reef, of which the Stiper stones are the remaims, and 
furnished the materials of the surrounding beds. 
5. This view is borne out by an examination of the Hapa Quarry, 
where a peak of Llandeilo flags is seen rising in the middle of the 
Caradoc, and around the peak is accumulated a similar nee = 
of peculiar species, especially univalves.
