Here  the  beds  below  the  horizon  of  lihynclioneTla  ringens  are  evi¬ 
dently  thicker  than  at  Halfway  House — 3  feet  10  inches  as  compared 
with  about  2  feet  6  or  7  inches — and  the  sands  were  not  reached. 
Till,  ringens  appears  just  above  an  existing  divisional  plane,  instead  of 
just  below  it ;  but  these  divisions  are  merel}*  local  and  accidental,  as 
the  field-quarry  at  Halfway  House  proves.  Strata  of  the  discitce 
hemera  may  be  recognized  here,  and  very  likely  the  succeeding  bed 
was  deposited  during  the  Sauzei  hemera.  Above  that  is  the  most 
remarkable  bed  in  this  part  of  the  district,  Bed  Xo.  4.  It  contains 
a  fauna  characteristic  of  the  Humph ri esiani  hemera,  which,-  exclud¬ 
ing  the  doubtful  Halfway  House  Bed  7,  had  not  been  previously 
noted  in  the  district  by  the  route  travelled.  It  contains  some 
remarkable  brachiopoda ;  in  fact,  by  working  beds  of  this  descrip¬ 
tion  I  was  able,  after  a  few  months’  labour,  to  add  to  the  braehiopod 
fauna  of  the  district  very  many  species  that  had  not  been  obtained 
before.1 
Above  this  bed  is  seen  the  same  4  Astarte- bed  9  which  is  found 
both  at  Bradford  and  Halfway  House  ;  but  here  evidently  a  lower 
horizon  is  included  in  this  bed  than  is  the  case  at  Bradford — namely 
that  of  the  niortensis  hemera  with  Ancylocercis ,  the  4  Bifurcaten- 
Schichten  ’  of  Quenstedt.  Fossils  labelled  4  Halfway  House  ’  suggest 
that  this  horizon  is  included  in  Bed  6  at  that  place ;  but  there 
is  no  such  evidence  with  regard  to  Bradford. 
In  the  top  of  the  Louse  Hill  Quarry  a  small  species  of  Aulaco- 
thyris 2  is  found,  and  this  fact  becomes  important  for  comparison 
with  Sherborne  quarries.

Plates  xviii.-xx..  Palmont.  Soc.  1884. 
2  It  has  usually  been  known  as  ‘  Waldheimia  Meriani,  variety ;  ’  but  it  is 
certainly  not  the  same  as  the  Cotteswold  fossil.
