MESSES. A. J. JUKES-BROWNE AND W. HILL I [May 1 896, 



A mile north of Notre Dame de Con? son a new section in a road- 

 cutting was fortunately seen, showing about 9 feet of soft, exceedingly 

 glauconitic sand, and about 100 yards north of this the section was 

 carried higher in the bank of a short cutting in a lane. Here there 

 occurred about 2 or 3 feet of greyish calcareous and rather marly 

 sand with rusty markings. It contained many fragments of Pecten 

 asper, and the material was very similar to that found at the summit 

 of the Greensand at Vimoutiers, 6 miles southward. No hard cal- 

 careous masses were seen, but we think that this grey calcareous 

 marl was undoubtedly the top of the Greensand. 



Yimoutiers was the next place of interest, and we have heartily 

 to thank M. Lecoeur, of this town, for his kindness in accompanying 

 one of us to the principal sections in the neighbourhood, and also lor 

 his generosity in adding some named specimens to our collection of 

 fossils. Nowhere else was the whole Cenomanian so well shown as 

 in the large quarries near here, which give almost a complete section 

 from the Greensand below to the Craie marneuse at the top. Besides 

 this, continuous railway-cuttings enable one, armed with proper 

 authority, to study the upper part of the Cretaceous series far above 

 the beds in which we had especial interest, and one could not help 

 regretting that time allowed the study of the basal portion only. The 

 following section was taken at a very large quarry, nearly a mile 

 north-east of the church : —

Feet. 

 C Soil, etc 1 



Greyish, glauconitic, sandy chalk weathering 

 to mealy dust, rather harder rough rock 

 alternating with smoother layers, cherts 

 scattered or in discontinuous lines 37 



Yellowish-grey, glauconitic, sandy chalk, 

 rough, with hard irregular lumps (not 

 nodules), softer chalk between 6 



Massive grey cherts, apparently a continuous

Yellowish-grey , glauconitic, sandy chalk, rough 

 and lumpy, softer mealy chalk between the

A line of separated cherts 



Yellowish-grey sandy chalk, rather glauconitic, 

 with lighter patches, massive cherts irre- 

 gularly scattered — passing down to 6 



Yellowish-grey, rather soft, mealy, and very 

 glauconitic sandy chalk containing hard 

 siliceous concretions 6 



A bed of detached, hard, calcareous masses, 

 very glauconitic, forming a marked hard

Greyish-green, very glauconitic, calcareous, 

 sandy marl with rusty markings, passing 

 down to dark green glauconitic sand, which 

 gradually became darker and was almost 

 black at the base 10

The Corallian immediately underlies the Greensand, but the actual 

 junction is not seen in this quarry.
