separately  was  not  possible  in  the  time  at  my  disposal.  In 
the  neighbourhood  of  Broad  Windsor  the  strata  of  these 
hemerae  may  be  studied  to  far  more  advantage. 
3.  Truellii  ( Strigoceras  Truellii ,  d’Orb.,  sp.,  sensu  stncto). 
4.  Gavantiance  (ParJcinsonia  Garanticina,  d'Orb.,  sp.). 
5.  Niortensis  (Parkinsonia  niortensis,  d’Orb.,  sp.). 
6.  4  Humphriesiani  ’ 1  (Stephanoceras  Humphriesianum,  Sow.  sp.). 
7.  Sauzei  (‘ Stephanoceras,  Sauzei,  d’Orb.,  sp.). 
8.  Witchellice ,  sp.2  There  are  numerous  species  of  Witchellia  in 
the  strata  of  this  hemera ;  but,  as  very  few  are  named,  it  is 
desirable  not  to  appropriate  any  particular  specific  name  at 
present. 
9.  Discitce  (. Hyperlioceras  clis cites,  Waag.,  sp.). 
10.  Concavi  ( Lioceras  concavum,  Sowerby,  sp.). 
11.  Bradforclensis  ( Lioceras  bradfordense ,  S.  Buckm.), 
12.  Murchisonce  (Ludwigia  Murchisonce ,  Sow.,  sp.). 
It  may  be  noted  as  a  matter  of  history  that  in  my  paper  of 
1881 3 4  the  divisions — 
1-4  were  included  as  PcirJcinsoni- zone, 
5-8  (pars)  „  „  Humphriesianum-zone, 
Si(pars)-10  „  „  Sowerbyi- zone, 
11,  12  „  „  Murchisonce-  zone. 
Subsequently  the  divisions  9-10  were  called  the  concavum- zone ;  and 
Waagen’s  term  4  JSoiverbyi-zone  ’  was  given  to  that  which  on  palae¬ 
ontological  grounds  was  assumed  to  be  an  horizon  situated  between 
7  and  9.  Practically  speaking,  the  correctness  of  the  surmise  has 
been  confirmed. 
In  describing  the  following  Sections  I  have  introduced  the 
quarrymen’s  names  for  the  beds,  when  they  could  be  ascertained : 
these  names  are  given  in  small  capitals  between  inverted  commas. 
The  names  by  which  the  beds  are  known  to  geologists  I  have 
placed  also  in  inverted  commas,  but  in  ordinary  type.  The 
quarries  are  taken  from  west  to  east,  as  directly  as  their 
position  and  features  allow. 
The  first  section,  known  as  Stoford  Quarry,  lies  just  on  the  borders 
of  Somerset,  on  the  north  side  of  the  Southwestern  Bailway,  and  a 
few  yards  west  from  Yeovil  Junction,  which  is  in  Dorset. 
1  The  confusion  concerning  this  specific  name,  and  the  large  number  of 
species  of  Stephanoceras,  make  this  appellation  very  unsuitable.  It  would  be 
desirable  to  apply  the  name  of  a  species  belonging  to  a  less  prolific  genus. 
2  This  term  has  been  suggested  by  French  authors  as  a  name  for  the  strata 
of  this  horizon,  from  the  prevalence  of  species  of  this  genus  in  France ;  see 
later,  p.  519.

4  So  far  as  the  Ammonites  from  Sandford  Lane  were  concerned  ;  but  the 
strata  were  covered  up — I  had  not  seen  them.
