HUGHES : INGLEBOROUGH.

In the Ingleton quarries, although the rock is here wedged 
in between two great faults, we know that we are not very far 
from the base as it is seen in the stream below. The fossils 
we have recorded from these beds are Bellerophons up to five 
inches across the mouth. 
Producta cor a. 
P. striata. 
P. Martini. 
Chonetes papilionacea. 
Cyathophyllum Murchisom. 
Amplexus. 
In Robin Proctor's Scar (see Plate XXXIII., Fig. 1) I have 
found — 
Producta striata (Fischer). 
P. fimbriata (Sow.). 
P. punctata (Mart.). 
Spirifera [Martinia] glabra (Mart.). 
Athyris expansa (PhilL). 
Orthis [Schizophoria] resupinata (Mart.). 
Streptorhynchus [Orthotetes] crenistria (Phill.). 
Cyathophyllum. 
In Thwaites Scar fossils are fairly abundant, and as among 
them we find Dibunodon and Producta Martini, and a little 
higher Chonetes papilionacea, Lithostrotion Portlocki, and Alveolites 
sej)tosa, as well as many forms of wider and longer range, such 
as Spirifera glabra, it is obviously a great help to be able to trace 
this horizon by such a conspicuous feature as these scars present. 
In the grey limestone of the Great Scar, on the northern 
part of Sulber (see Plate XXXIV., Fig. 1), near Simon Fell 
Nook, I found the following species : — 
Producta semireticulata (Mart.). 
P. longispina (Sow.). 
P. pustulosa. 
Spirifera [Martinia] glabra (Mart.). 
Sp. hisulcata-. 
Sp. pinguis (Sow.). 
Sp. trigonalis (Mart.).
