236 REPOfttS ON THE StAtE OF SClExVCE. 



No. 2. — Excavation and Section in fields 200 yards south of 



the Cornley Quarry. 



At this spot there was an old cutting overgrown with grass in a little 

 knoll near the southern termination of the Quarry Ridge (see map). 

 It showed protruding bosses of grit and conglomerate similar to those 

 seen in the Quarry, together with loose angular pieces of grey or purplish 

 limestone. 



I had one side of this cutting cleared of soil, and prolonged the 

 section thus obtained in both directions by a new trenching excavation. 

 The beds have a strike approximately north and south, and dip to the 

 east at an angle of about 65°. 



The old cutting and the new trenches are not quite at right angles 

 to the strike, but allowance for this has been made in taking the 



measurements

Ead m?}d of Section, 



a. The Quarry Ridge Shales : — 



Comminuted pale greenish grej' sbale, including (in the lower part 

 of its section) a band of hard glauconitic grit 3 inches thick, 

 striking parallel with the beds below. The base of this shale 

 group not seen owing to the presence of a fault running 

 nearly parallel with the ttrike and hading easterly. The 

 thickness of this group may be as much as 200 or 300 feet . 10 



i. The Quarry Ridge Grits : — 



6, Grit broken into angular fragments, say 5 



b.. Well-bedded grit 5 



h^ Conglomeratic grit with black flaggy material about the 



middle and at the base 12 



These grits and conglomerates agree precisely with those 



of the Quarry ((7,, a.,. Section No. 1). 



c. The Black Limestone : — 



The upper half of this shows a dark grey sandy matrix with many 

 black phosphatic lumps ; the lower half has less of the 

 phosphatic material ......... 1 



Hyolithus fistula, HoU. (?). 



d. The ' Grey Limestones ' : — 



A series of fossiliferous limestones varying in colour from a reddish 



purple ihrough greenish grey to pale grey. 

 (l^ A pale grey limestone very full of fossil fragments ... 3 

 Fossils: — Protoleniis sp. ; Mivrodisous lohatus, Hall; M. s^p.^ of 



medium size and having a punctate test.; i1/. sp.„ somewhat 



intermediate between the two ; Hijolithus, cf. II. corneohis, 



Holm.; Il.fistvla. HoU. (?), and Brachiopods. 



d. A reddish purple limestone becoming pale grey in places . . 6 

 Fo.'-sils are very plentiful : — Microdiscus lubatns. Hall ; M. 

 gpeciosus. Ford ; Anomocare (Affraulos of Mathew and Wal- 

 cott), cf. A. stremms, var. nasutus, Walcott ; A. sp.,, wiih 

 glabella furrows transverse ; A. sp.^, with glabella furrows 

 directed backwards; A. sp 3, a smaller form, with front 

 margin reflexed and glabella almost keeled ; Hyolithut 

 fistula, HoU.C?); H. sp., cf. H. lenticulo/ris. Holm.; H". sp. ; 

 Helenia (J) sp. nov. and Brachiopods.
