104 Morris — Oolites of Northampton, 8fc. 



Welland, belong, by its fossils, to the Inferior Oolite, and, probably, 

 represents in time part of the " Dogger beds" of Yorkshire. 



2. That the Sands and concretionary calcareous Sandstones known 

 as the Collyweston and Wittering slates, as well as a part, if not all, 

 of the overlying Oolite (Ponton, Corby, Stamford, Barnack, Morcot,) 

 also belong, by their fossils, to a higher zone of the Inferior Oolite, and 

 may be the equivalent in time of the beds overlying the Dogger. 



3. That the Upper White Limestones and Shales, over certain 

 parts of the area of Northamptonshire, are the representatives of the 

 Great Oolite. 



4. That in the Upper and Lower Oolites of Lincolnshire, above the 

 red rock, there are very few Cephalopoda, and that the lower zone 

 is marked by the prevalence of Nerincea, Astarte, Tancredia, Quen- 

 stedtia, Trigonia, Cardium, Cucullcea, Alaria, and a large Natica, as- 

 sociated with fragments of Pterophyllum and other Cycads, and 

 JPecopteris polypodiodes, a species largely represented in the Oolitic 

 Shales of Yorkshire. They have been placed provisionally upon the 

 horizon of the Great Oolite, but their fauna would seem rather to 

 connect them with the Inferior Oolite,^ Lycett. 



5. That from the general fossil contents of these beds, they pre- 

 sent characters intermediate to the more truly marine conditions of 

 the south-western or Gloucestershire area, and the Fluvio-marine 

 and TeiTestial deposits of Yorkshire. 



6. That the Collyweston slates contain chiefly a molluscan facies, 

 while those at Stonesfield comprise a rich and varied fauna of shells, 

 Crustacea, insects, fishes, reptiles, mammals, and many plants. 



The following are some of the localities where sections may be 

 observed and fossils obtained, in illustration of the preceding 

 remarks : — 



1st. Southern Area. — Pits around Ellsworth, where the Lias, Red 

 Eock, and Oolites may be seen. 



The quarries around Northampton, and northwards at Kingsthorpe, 

 Moulton Road, and at Duston, beyond Dallington. 



The pits around Wollaston where the Upper Oolite with T. digona 

 may be seen. 



Higham Ferrars, Eaunds, Stanwick, and Oundle, (where OpMo- 

 derma Griesbachii was found. 



The sections near Wellingboro', Kettering, Finedon, etc. 



The quarries around Wansford, where Dr. Fitton mentions that 

 the fern referred by Lindley and Hutton to Lonchopteris Mantelli, 

 was found, from which it was inferred that traces of the Wealden 

 occurred in Northampton.^ 



2. Northern Area. — The pits around Stamford, Casterton, and 

 Ketton. The quarries at Collyweston and Easton, and further west 

 at Morcot and Luffenham. 



Unfortunately the collection made by me, which would have 

 afforded incontrovertible paleeontological evidence of the beds in this
