HIND : CARBONIFEROUS ROCKS OF THE PENNINE SYSTEM. 431 
Dark soft shales, 3 ft. 
Limestone composed of rolled shells, corals, crinoids, 
and fragments of limestone, comparable to the 
Beach Bed of Castleton, 3 ft. 
Shales, 2 ft. 
Shaley limestone, 1 ft. 
Shales, 1 ft. 
Thick limestone, 6 ft. to sole of quarry. 
At the north end of the quarry the middle beds are disturbed 
and folded, but the upper and lower limestone are not aft'ected. 
The fauna here is extensive. Some of the calcareous shales 
are crammed with crinoid joints and fragments of Palaechinus. The 
shelly limestone contains : — 
Glyphioceras crenistria. 
„ sphcericum. 
Rhynchonella pleurodon. 
Productus giganteus. 
„ longispinus. 
„ striatus. 
„ semireticulatus. 
Chonetes papilionacea. 
Spirifera trigonalis. 
,, lineata. 
,, glabra. 
Dielasma sacculus. 
Strophomena analoga. 
Lithostroiion M artini. 
Crinoids sp. 3. 
A very noticeable feature in a rolling hill passes south from 
this quarry in the direction of the Knotts, which we cannot but think 
indicates a continuance of the limestone. 
About a mile and a half north-west a narrow lenticle of lime- 
stone is mapped. In this occur an interesting series of quarry 
sections showing a similar series to the Brockthorns quarry.
