INFERIOR OOLITE : KETTERING. 
189 
The beds are faulted at one point, and the Lower Estuarine beds are 
brought against the Upper Lias Clay, the downthrow being from 12 to 
15 feet. The fault ranges from N.W. to S.E. 
The identification of the beds at the Kettering quarries with the 
Lower Estuarine Series, is proved by the important sections at 
the Lime-kiln quarry and Ironstone-workings at Glendon, west of 
Weekley Hall Wood. The beds shown were as follows (see

The quarry in the Lincolnshire Limestone at Glendon Wood, 
was visited on a celebrated occasion in the summer of 1869, by 
Sir A. C. Ramsay, Mr. Etheridge, Mr. Howell, Prof. Judd, and 
the late Samuel Sharp.* They then obtained a number of fossils, 
which proved the strata to belong to the Inferior Oolite. The 
following are among the species that occur : 
Natica cincta. 
Nerinaea cingenda (Fig. 22). 
Cardium Buckmani. 
cognatum. 
Ceromya bajociana (Fig. 21). 
G-ervillia acnta. 
Lima pectiniformis. 
Lucina bellona. 
despecta. 
Myacites scarburgensis. 
Pecten personatus. 
Pholadomya fidicula (Fig. 11). 
Pinna cuneata. 
Tancredia axiniformis. 
Trigonia hemisphaerica. 
Galeolaria (Serpula) socialis. 
Acrosalenia Lycetti. 
Pygaster semisulcatus (Fig. 25). 
Corals.
