somewhat conglomeratic. From the top beds — so the workmen said — was 

 obtained a specimen of Pleurotomaria cf. actinomphala. A fragment of 

 Lytoceras aff. Eudesianum was found on the spoil-heap. Both these finds are 

 curious because, from the position of allied forms in Dorset, they would be 

 expected to characterize beds of the Sauzei or Humphriesiani hemerze. 



The celebrated locality of Birdlip is reached 3 furlongs farther 

 on ; but the place is disappointing. The best exposures have been 

 fenced in for private gardens, pleasure-grounds, and the like. An 

 exposure in Whitcombe Wood is somewhat overgrown and obscured. 

 The sections show the Upper Trigonia-gvit resting on Upper Free- 

 stone. About 3 feet of unf ossiliferous beds separate the Upper 

 Trigonia-grit from the Glypeus-gnt — the latter a very distinct rock, 

 rubbly, iron-stained, containing soft marly patches, with large 

 Terebratula globata, T. birdlipensis, and Olypeus Ploti. 



Two-and-a-half furlongs from Birdlip — continuing the same 

 general line — is Cuckoo Pen Quarry. Here the ' intervening beds ' 

 are once again met with. They are about 3 feet thick, all pre- 

 sumably belonging to the Lower Trigonia-grit. The following 

 section was noted : — 



Section XV. — Cuckoo Pen Quarry. (From Birdlip, 2| furlongs on 

 the right-hand side of the road to Cheltenham ; from Stroud, 

 7\ miles jST.E. ; from Leckhampton Hill, 2 miles 3 furlongs 

 S.W. by S.)

From Cuckoo Pen to the next quarry, Tuffley's, is f mile. Here 

 the thickness of the intervening beds is increased nearly 6 feet by 

 the addition of the Buchnani-grit ; but it will be seen that, while 

 the lower part of this grit is of the usual thickness, the upper part 

 is deficient in that respect. It is, therefore, removal of the upper 

 part, and not attenuation of the whole bed, which accounts for the 

 want of thickness of the Buckmani-grit. This is an important fact ; 

 but it fits in exactly with what has been observed in the sections 

 given in these pages, both approaching and leaving Birdlip. 



Section XVI. — Tuffley's Quarry, by the Air Balloon. (On the left- 

 hand side of the road from Birdlip to Cheltenham ; from Stroud, 

 8 miles N.E. ; from Leckhampton Hill, 1| miles S.W. by S.)
