had visited the latter locahty at Easter, those who attended both excursions had a 

 good opportunity of comparing the two. The state of tlie fossils (occurring chiefly 

 as compressed casts) is exactly the same, and altogether there is a general external 

 resemblance, which is very strikin g. Moreover, in each case, fossils are very abun- 

 dant, but of a somewhat different /ar/^j-. Gervillia acuta occurs plentifully in each, 

 and there is likewise here a Trigonia not unhke T. impressa of Stonesfield, but 

 beyond this point there is not much resemblance in their respective faunas. The 

 party collected several species here, as Hinnites velatiis, Pin7ia nineata, AviciUa 

 Braamburensis, Ceromya sp., Cardhim jBticktiiattni, OicuUma cancellaia, Modiola 

 Sowerbyana, Trig07iia pullus^ T. compta, and, most characteristic of all, Pierocera 

 Bentleyi. Plants and some teeth and scales of fish occur ; but the formation 

 appears deficient in the remains of insects, reptiles, mammals, which are the glory 

 of the Stonesfield beds. After a delightful drive through Ketton, and thence along 

 the Stamford Uppingham high-road to Lufifenham Station, the party took the rails 

 once more, and arrived at Northampton at 7 P.M. Before finally separating, the 

 thanks of the excursion party were most heartily tendered to Mr. Sharp for his 

 hospitality on the previous evening, and for the kindness and unwearied zeal which 

 he had exhibited during two long and arduous days.

1. " On the Lower Cretaceous Beds of Folkestone." By F. G. H. 

 Price, Esq. 



The town of Folkestone is situated upon the Folkestone-beds of 

 the Upper Neocomian. These the author divides into four lithological 

 groups, commencing with a sandy bed containing many phosphatic 

 nodules, and which he considers to form the true division between 

 the Folkestone and underlying Sandgate-beds. The RTiynchonella 

 sulcata bed, an important fossiliferous zone, lies at the base of the 

 latter. 



The general character of these Folkestone-beds is that of a loose 

 yellowish sand, parted by seams of coarse calcareous sandstone. 

 Masses of branching sponge are especially plentiful in these rocks. 

 The last bed of the Folkestone series is a very remarkable one, 

 consisting of four irregular seams of large nodular masses, composed 

 of coarse grains of quartz, glauconite, jasper, lydian stone, and phos- 

 phatic nodules. Its fossil contents occur mostly as rolled phosphatic 

 casts. This is the zone of Am. mmnmillaris. 



Four feet of loose sands succeed, capped by a line of pyritous 

 nodules ; and then occurs a seam of dark greensand, containing two 

 lines of phosphatic nodules, largely charged with Am. interruptiis, 

 and other fossils in the form of rolled casts. Upon fragments of 

 Am. interriiptus occur PUcatula pectenoides, Pecten quinquecostatus, 

 Trocliosmilia sulcata, and Nucula sp., forms contemporaneous with 

 the bed. 



The argillaceous-beds of the Lower Gault, which succeed, are 

 frequently very dark in colour, and more or less parted off by lines 

 of nodules, marking certain zones of life which the author had 

 already described in considerable detail in a recent communication 

 to the Geological Society. They are very rich in well-preserved 

 fossils, one bed in particixlar, towards the top of the group, is full 

 of Gasteropoda. With two exceptions, the ammonites belong to the 

 Dentati and Tuherculati. The thickness of this sub-formation is about 

 28 feet. From the grey marl or Upper Gault it is separated by a
