242 MR. A. J. JUKES-BEOWNE ON AN OUTLIER [Aug. 1898, 



stratigraphical position as the Beer Stone, the section in the larger 

 quarry at Beer may be given for comparison with the above : — 



Feet. 



/^Soil and broken chalk 9 



Zone OF j White chalk with many layers of flints 24 



Terebratula •{ White chalk with few flints ; Terebratula gracilis 17 



GRACILIS. I SoftJ white chalk, passing down into rough nodular 



\^ ch alk ; Echinoconus subrotuoidiis 2^- 



(Hard compact yellowish limestone, passing down into 



Zone OF | hard shelly chalk 2 



EiHYNCHONELLA ■{ Eough yellowish nodular chalk, with Inoceramus myti- 



CuviERi. I hides, Ehynchonella Ctivieri, etc 14^ 



l^Good crystalline freestone in several beds 13 



82 



The beds below are not now exposed, but it is known that 

 5 or 6 feet of rough splintery chalk occurs beneath the above, resting" 

 on hard chalk with grains of quartz and glauconite. 



Eeturning to Widworthy, the freestone has also been quarried 

 in the Park east of Widworthy Court, but no exposure is now open. 

 A sand-pit, north of Wilmington and | mile north of Widworthy 

 Church, discloses the existence of another small outlier of the 

 Turonian Chalk, and is interesting as showing its junction with 

 the beds below. The section here is as follows : — 



Ft. In. 



f5. Soft white chalk 2 6 



Turonian | 4. Hard rubbly chalk, very hard at the top and 



■\ containing green -coated nodules, more 



[=MiDDLE Chalk.] j massive below, with grains of quartz and 



I glauconite 2 6 



1^3. Soft marly glauconitic chalk 9 



f 2, Hard quartziferous limestone with glauoonite- 



p j grains ; upper surlace well marked and 



J encrusted with brown phosphate ; base not 



r_T PR Phalk 1 I well marked 2 



L" 'J 1 1. Rough calcareous sandstone full of fossils, 



l^ weathering into sand with hard lumps : about 6 



These beds are cut off by a fault at the northern end of the pit, 

 but the throw is not more than 8 feet, and on the north side the 

 rough fossiliferous sandstone passes down into coarse calcareous 

 sand with few fossils, of which about 18 feet is seen. 



No. 4 of the above section contains Inoceramus my tiloides, hut no 

 other fossil was seen in it nor in No. 3. I regard these as the 

 basement-beds of the Turonian or Middle Chalk. 



In No. 2 I found Scaphites cequalis, Turrilites costatus, Holaster 

 suhglohosus, Osirea vesicularis, and Discoidea suhuculus. This bed 

 is clearly the equivalent of the uppermost Cenomanian bed on the 

 coast, that which is numbered 12 in Mr. Meyer's Beer Head section. 



The fossils of No. 1 include Ammonites Mantelli, A. naviculca^is^ 

 Pecten asjoer, Lima semiornata, Holaster suhglohosus, H. altus, 

 H. carinatus, Pseudodiademn variolare, and Phynchonella dimidiata. 

 This bed and the underlying sand correspond with the similar 

 calcareous sandstone at Beer Head (No. 10 of Mr. Meyer).
