Paridi of Great Roh right^ Eaftward from the Churchy whereof 
fomeare fo foft, that 'tis eaiieto prefs them afunder with ones 
fingers; and others a hard bluifi fione. But though they agree 
with theform.er ia the manner oi produSiion^ they differ as much 
in the manner of their lineations^ for whereas their i7ric€ were di- 
vided near the rim, fomeof the lineations thefe come toge- 
ther there, and are united in pretty large protuberant knobs on 
each fide the bi ck of the fione^ which in thefe being broad and 
fomwhat rifing, is croiied by other arched Yuies that intercede the 
eminencies^ as in Fig, 13. 
93. Other Ophiomorpbit's there are, that have only flraight 
fingle n7;5, which terminate alfo in ftraight ridges that run along 
on each fide the back of the fione ; between which two ridges^ 
there rifes a third moit prominent one, jufi: in place as it were of 
the Spina dorfali^^ as in Tab. 5 . Fig. 14. which though not wreath- 
ed, but plain like the other lower ridges on each hand it, I take 
to be the Cornu Jmmonis criflatuvi of Johannes Baubinu6 One 
of thefe, of about four inches over, and made up of as many 
turns^w'ds given me by the Reverend and Learned Dr. John Walli^ ; 
and there is another amongd the Ko^'A/a of the Medicin School^ 
of above eight inches diameter., taken up as they fay fomwhere

94. There are alfo 0 rphiomorphit' ?> found fomtimes about 
^dderburji^ about two miles from Banbury^ but fo very feldom, 
that though I were there often, I could meet with none of them ; 
fo that cannot inform the Reader whether they are of any pecu- 
liar kind, different from what have been already defcrib'd,or no ; 
However, that the Town has not its name from thefe Rones (as 
Mr. Ray thinks) I dare confidently avouch, ^dderbury being only 
the vulgar name : for in the Co^/r/ 7?o//^ of New College^ (ando- 
orher Inftruments) to which the Lordfiip of the Tovpn belongs,it is 
written Eabberbury^ perhaps from Sc. Ebba the tutelar Saint of the 
Church.
