166 De Ranee — On the Albian, or Gault of Folkestone, 



The last set of bones found were exhumed in the presence of 

 Captain Sweeney, R.A., who told me they were found in bed 6 of 

 this section, two or three large tusks of Elephas pri^nigenius being 

 left at the bottom of the excavation, where they remain to this day. 

 A similar deposit to that of bed 4 of the above section, was found 

 in an excavation for some cottages, between the New Gas Works 

 and Railway Embankment ; this deposit, capped by brick earth and 

 resting on Upper Aptian, contains Lower Chalk fossils and nodules 

 of iron from the Chalk. 



The junction bed xi, may be well seen on the Canterbury Road, 

 in a sand pit, a little south of the brickfield above the Red Cow Inn ; 

 the zone of Am. interruptus resting here on the zone of Am. mam- 

 millaris, at a height of forty feet above the road. At the gate leading 

 to the brickfield it dips under the road, and is never met with at the 

 surface further north. It was, however reached in a well-sinking 

 at Canterbury Terrace, Dover Road, at a depth of eighty feet. The 

 two upper bands of bed xi. were three feet six inches, and the 

 sulphuret of iron seam eighteen inches in thickness ; water was 

 touched the moment the latter seam was pierced, and welled up in 

 abundance after passing through five feet of dark greensand, re- 

 sembling in lithological character the beds of the Middle Aptian. 



Zone of Ammonites Benettianus {?) Bed x. — The "bottom bed " of 

 the Albian contains one seam of phosphatic nodules, with few 

 organic remains. 



Zone of Am. auritus, var. Bed ix. — The variety of Am. aicritus 

 found in this zone has long and slender spines. The zone is well 

 shown in the Copt Point section, in the patch of Albian exposed on 

 the beach in the Eastwear Bay, between Copt Point and the Pre- 

 ventive Station, and in the Brickfield before mentioned. 



Zone of Crustacea. Bed viii. (" Crab-bed ") is composed of a light 

 fawn-coloured clay ; a striking contrast to the deep black of zone ix., 

 and is poor in fossils in proportion to its thickness, but contains 

 seven species peculiar to itself. 



Zone of Nautilus Clematinus. Bed vii. — The clays of this zone are 

 strongly spotted with light markings of fawn colour on a dark 

 ground ; this kind of mottling is invariably found in the clays of the 

 Lower Albian ; on the contrarj'-, in the Upper Albian, the clay 

 deposits are streaked (not spotted), with dark marks on a light 

 ground. Many characteristic Albian shells make their first appear- 

 ance in this zone, and seven are peculiar to it. 



Zone of Am. denarius. Bed. vi. though of small vertical thick- 

 ness and lithologically similar to the last, is palseontologically 

 distinguished from it, from the fact that many of the most marked 

 forms of zone vii. do not pass into it, while on the other hand it 

 contains at least six species peculiar to itself. This zone is well seen 

 in plan, in the patch of Albian on the beach ; it is there distinguished 

 from the last by the darker colour of the ground between the 

 mottlings, and is physically separated from the following zone by a 

 Beam of hard rag about six inches thick. 



Zone of Am. auritus. Bed. v. is very dark in colour, though
