wilmore : thornton, marton and broughton-in-craven. 355 
Brachiopods 
Athyris planosulcata ; specimens are sometimes 1 J inches 
in width. 
Orthotetes crenistria, very common. 
Chonetes Hardreiuis (PhilUps). 
Producius pustulosus. 
P. scabriculus. 
P. subloevis (Kon.). 
The Hmestone of this quarry, when sectioned, shows nu- 
merous foraminifera, along with fine detritus of shells, corals, 
and echinodermata. There is one band of " shell breccia," 
in which fragments of shells, chiefly Athyrids, occur in a matrix 
containing much iron-carbonate, which weathers to hydrate. 
I take it that these beds, possibly along with those of Rain 
Hall Plantation, represent the lowest beds seen in this anticline. 
The next important exposure is that of Rain Hall Quarry, 
number (6) on map. This is classic ground, having been visited 
by Phillips. The Geological Survey Memoir describes it at 
some length ; and ^lessrs. Hind and Howe refer to it in their 
paper on the Pendleside beds at Pendle Hill, &c. 
It is a long quarry, following the strike of the beds, and 
it has a branch of the Leeds and Liverpool Canal running almost 
to the limits of quarrying operations. It has long been dis- 
used and is now partly grown over. There is much disturb- 
ance, and at the western end the dip changes considerably and 
the beds become almost vertical. At the eastern end there is 
also some " rolling." Near the rrdddle of the quarry there is 
a small fold, and beds are seen with a dip to north-north- west,* 
this part, however, being much grown over. The general dip 
is south-south-east, at an angle varying from 50° to 70°. There 
is much slickensiding, and some of the shales are strongly con- 
torted, it being possible to obtain hand specimens which are as 
much contorted as some of the schists of, say, Anglesea. 
The same type of dark limestone occurs, but there is also 
a grey crinoidal breccia, which is not represented in the quarries 
already described. This bed contains abundance of Caninia 
cornucopice, Mich., and I refer to it as the Caninia bed. There 
* I have to thank Mr. T. E. Brown for calling my attention to this.
