MISS G. E. WATNEY AND MISS E. G. WELCH ON THE [May 191 I, 



Cyrtograptus-lundgreni Zone (C 4 ). — This zone is best 

 exposed in a small stream-section occurring in a larch-wood above 

 Handley's Bridge. The rocks dip at 25° west by south, and are 

 massive, blue, banded flags containing the characteristic zonal 

 graptolites. 



There are no other exposures of this zone on the eastern slope 

 of Wandale Hill, but the fossils may be picked up in abundance at 

 the gathering-grounds of the gills. 



A massive grey-green grit occurs near the top of "Wandale Hill : 

 it is unf ossiferous, and probably forms part of the Lower Ludlow 

 Series, since nowhere in the area does a grit appear in the Upper 

 Wenlock.

West Wandale. 



On the west side of Wandale Hill the Wenlock again crops out, 

 and the Lundgreni Zone (C 4 ) is found overlain by the Monograptus- 

 nilssoni Zone (D x ) of the Lower Ludlow. The Lower Wenlock 

 zones are cut out by the Wandale-Hill fault, which has let down 

 the Upper Wenlock and Ludlow Beds against the Browgill Beds 

 and the Coniston Limestone Series. 



The only exposures occur in a small gill, which flows dowD from 

 the site of an old quarry above Narthwaite to join Backside Beck. 

 Where the gill crosses the Mountain-View Eoad, the Coniston- 

 Limestone Beds are faulted against the Wenlock strata. These 

 appear as blue finely-banded flags, with many concretions. The dip
