the Pea-Grit let down beyond, has been disclosed. The Pea- 

 Grit here resembles its equivalent in the next quarry (No. 5), 

 and yields Terebratula Whitakeri, T. plicata, J. Buckman, T. 

 pisolitica, S. Buckman, Rhynchonella subangulata, Dav., etc. 



In the next quarry (Nos. 4 and 5 of Witchell) the top- 

 portion of the Lower Limestone is visible with Pea-Grit above. 

 In the eastern portion of the southern face the Pea-Grit 

 is let down by faulting some 4 feet, and this fault is probably 

 a continuation of that noticed in the preceding quarry. A 

 view of the western portion of the south face of the quarry is 

 given in Plate XVIII., fig. 2, and details of the beds in the 

 general record on page 126. Attention may be specially di- 

 rected to the regular and worn aspect of the top-surface of the 

 Lower Limestone, and to the probable occurrence of a slight 

 non-sequence between the Limestone and the Pea-Grit — the 

 Pea-Grit present being the top-portion of that subdivision. 



About 300 yards further on up the trackway is quarry 

 No. 2 of Witchell, in which is seen the top-portion of the 

 Lower Freestone, the Oolite Marl, Upper Freestone and over- 

 lying Upper Trigonia-Gvit : but no Gryphite-, Buckmani-, or 

 Lower-Trigonia-Griis it should be noted. In the south- 

 eastern corner a trough-fault will be noticed — the Upper 

 Trigonia-Grit having been introduced in between the Bradford- 

 ^wsis-Beds, which therefore flank it. The Oolite Marl is very 

 feebly developed here, and at its horizon the beds exhibit 

 considerable variation, and are consequently difficult to mea- 

 sure accurately. The main feature is the large replacement of 

 marl by limestone replete with a new Rhynchonella, Rhyn. 

 Witchelli, Richardson, which is common here but comparatively 

 rare elsewhere. 



In the shallow quarry near the Tumulus (No. i of 

 Witchell), the top of the Upper Trigonia-Gni can readily be 

 found by means of the layer of oysters, and resting thereon is 

 a bed of very distinctive lumps of limestone containing Tere- 

 bratula subsphceroidalis, Upton, and a new species of Rhyn- 

 chonella. Rubble of typical Clypeus-Grit succeeds. 



The sequence from the Lower Freestone to the Clypeus- 

 Grit is excellently seen in Leigh's Quarry (see map and Plate 

 XVIII. , fig. i). The lower portion of the Upper Trigonia-Gnt 

 Witchell thought was Gryphite-Grit ; but there are no 

 " Intervening-Beds " here.
