ON THE FOSSILIFEEOUS TRANSITION BED IN NOnTUAMPTOXSIIIliK. 337 



With regard to this section it may be observed that in no other 

 locality in the county have we found the Fish bed so distinctly separated 

 into two layers. 



Section at Bugbeook. 



(Mr. Ward's farm, near the village, and south of the railway.) 



Ft. iu. 

 B. — 1. Soil and blue clay, much disturbed, many little 

 planulatc Ammonites lying about on the weathered 

 surface 3 



C. — 2. Lower Cephalopoda Bed. — An irregular la.ver of 

 small water-worn stones of a ruddy yellow colour. 

 Oolitic in places, the broken surface across these 

 oolitic parts looking very like coral . . . G

 Kucula Hammvri. 

 JVaiitiliis, ^'c. 



D. — 3. Blue claj-, rather darker colour than usually met 

 with on this horizon, red and sandy at the top, 

 also very rudd}- and shaly towards the bottom. 

 Few fossils ■16 



EandF. — 4. Cephalopoda Bed (Inconstant Bed). — S. hard 

 bluish grey stone, weathering quite red at joints 

 and exposed surfaces — called ' Pendle ' by the 

 workmen. Many Ammonites of the falcifer group 

 and very few of the planulate, the former often 

 crushed quite flat, as they are in the shales below 8 



Nautilus astacoidcs ? large and small. 

 Ammonites exaratus. 



„ Sti'angwaysi, ^-c. 



The fine ribbed variety of A. Strangwaj-si seems 

 most often crushed. 



H. — 5. Paper Shale. — A grey, finely laminated shale, 

 weathering to a much lighter colour, containing 

 fish fragments and a good number of flattened 

 Ammonites — chiefly the fine ribbed variety of A. 

 Strang)vaysl . . . . . . . .04 



I. — 6. Fish Bed. — A bluish-grey stone, laminated like the 

 shales, and weathering quite white on the exterior. 

 Comes out in large flat slabs — only nodular in one 

 part, and that just over a large fissure in the rock 

 bed below 2 



Fishfragments fairly abundant, only small Ammonites, 



chiefly -1. latescens. 

 Saurian remains more abundant here than elsewhere 



in the same bed. 



J.— 7. Paper Shale like Xo. 5, though fewer Ammonites 

 probably 



L.— 8. Transition Bed. — Not present as a distinct bed, 

 and no red clay ; nevertheless clearly shown by the 

 altered character of the top of the rock bed, and 

 by the presence in this of Ammimitcs Holandrci, 

 Cerithiwm ferreum, sviall liJajnchonelhc, .ff. 



Nearly as hard as the rock bed itself. 

 No pebbles here.
