and larger furrows, defcending as ic were from a center atthetop, 

 and expanding themfelves to the rim of the ftone 5 having alfo 

 fix or {even tranfuerft fimple lines, bent circularly to the hinge or 

 commiffure of thevalves, as in Tab. 4. Fig. 3. which is a font 

 without, of a dark cinereous colour, but within, a black, flint ; 

 found fomwhere in the Chiltern about Henly upon Thames, and 

 kindly beftowed on me by the ingenious Mr. Munday, Phyfitian 

 there. 



65. Some there are again, whofe ftrice alfo defcend from the 

 hinge or commiffure, but not in ftraight li;;es, but bent and un- 

 dulated, and much broader than the former, as in Tab. 4. Fig. 4. 

 which though in magnitude it fall fhort of the Concha Tridacna of 

 Aldrovandut (fo called it feems becaufe they made three mouth- 

 fuls apiece) yet in form it (hews to be fo very like, as may be feen 

 alfo mjonflon, Tab. 13. that were it not a Hone, I mult pro- 

 nounce it the fame h . This I found at Great Holrvright in a bluifh 

 clay, whereof, and of nothing elfe, it feems to be concreted ; 

 for it do's not much exceed it in hardnefs, and ftill participates 

 moft of that colour, though covered with a bright and fhining 

 fubfiance, by the Natural ifts called Hoplites , or Armatura : of 

 which more anon when I come to Cornu Ammonium, a ftone, the 

 moftof any adorned with that fubfiance. 



66. Another fort there is found at Heddington Quarries, whofe 

 lines or Jrridezre not drawn like the two former, from the com- 

 miffure of the valves to the rim, but tranfverfly and circularly 

 from one fide of the ftone to the other ; the levler circles having 

 place next the commiffure, and the greater next to the rim of the 

 ftone, as in Tab. 4. Fig. 5. which feems much to refemble the 

 Concha rugata of ' Rondoletiu* \ with valves fwelling very high ; of 

 colour it is cinereous, inclining to yellow, not hollow within, but 

 a folid [tone, and of much the fame texture with the rubble of the 

 Quarry. 



67. Of the fmaller Conchites there are alfo feveral forts, differ- 

 ing in colour, lineation and valves ; for at Teynton and about Bur- 

 ford, where they are found jn the Fields, they are moftof them 

 yellow^ with their valves riling high and approaching to around *: 

 but at Glympton, where they are only found in a fpring that rifes
