The specimens in No. 7 were obtained by one of us from shelly 

 tenacious clay between the thin limestones dug for road-metal at a 

 spot called "Style's Close," at the north corner of the junction of 

 Dogsthorpe Lane with the Deeping Eoad, \\ mile north of Peter- 

 borough, just where the figures " 83 " occur on the Ordnance Map. 



On the other or west side of the Deeping Eoad, opposite to Style's 

 Close, and, like it, within the "Walton Fields," is the railway settle- 

 ment called " New England." From a well here, at the depth of 150 

 feet, a piece of Upper Lias yielded as follows :

 near Peterborough. 



Cristellaria. 



Pulvinulina (between P. elegans and P. caracolla) ; small and abundant. 



Lituola scorpiurus (dentaline and neat). 



Trochammina incerta [Tr. elliptic a ; oblong-oval). 



To illustrate the relative position of the Foraminifera-bearing beds 

 near Peterborough, mentioned above, the subjoined list of the Oolite 

 beds in the neighbourhood of Peterborough, from notes by Mr. J. 

 W. Judd, F.G-.S., will be of service to the collector, 1 for doubtless 

 very much more is to be done with the Jurassic Foraminifera. 



I. Lower part of the Oxford Clay; very dark blue shales, with shells. Stan- 

 ground, Fletton, and Woodstone brickyards. 



1 " The Geology of Peterborough and its Vicinity," by the late Dr. Henry Porter 

 (8vo., Peterborough, 1861), may be consulted for some useful details as known at 

 that date.
