ON THE BTOCKDALE SHALES.

spiaitjerus- zone (2 feet thick, but somewhat crushed), which yielded, 

 to a brief search, 



Monograptus spinigerus, Nick. 

 distans, Furtl. 



Diplograptus Hughesii, Nich. 



Two calcareous nodular bands of the ordinary kind occurred near 

 the top of the erinaceus-zone, which shows the usual passage into 

 the Browgill Beds, and is here 10 feet thick. 



Mealy Gill. 



Half a mile after leaving Yewdale Beck the Stockdale Shales are 

 again met with in Church Beck, where this stream is joined by a 

 tributary coming from the south-west known as Mealy Gill, and a 

 good section of the shales is exhibited in a wooded gully through 

 which the latter runs, and is found just above the bridge over 

 which a siding from the railway -station is carried.

The lowest beds seen are on the north-west bank of the stream, 

 as seen in fig. 6, which shows a restored section taken from diffe- 

 rent parts of the gill, so as to exhibit all the zones which we have 

 detected here in the Skelgill Beds. The Lower Skelgill Beds occupy 

 a great part of this bank, but in one place a fragment of the Jtmhri- 

 atm-zone occurs in which the fossils are beautifully preserved. 

 They include : — 



Monograptus fimbriatus, Mch. 



leptotheca, Lapw. 



Rastrites peregrinus, Barr. 

 Diplograptus sinuatus, Nich. 



Petalograptus ovato-elongatas, 



Kurck. 

 Climacograptus normalis, Lapw.
