ro6  SMITHSONIAN    MISCELLANEOUS    COLLECTIONS  VOL.    96 
Style  (pi.  24,  figs.  11-16),  and  these  same  heads,  it  will  be  recalled, 
came  mostly  from  the  deeper  parts  of  the  midden;  figures  17  and  18, 
also  ornamented  in  Old  Bering  Sea  style,  had  less  prominent  spurs. 
Those  of  smaller  size,  with  the  spur  simplified  but  still  irregular  (pi. 
24,  figs.  20-23),  ^"ti  which  according  to  stratigraphic  evidence  are 
definitely  later,  are  either  plain  or  decorated  in  early  Punuk  style. 
Here,  instead  of  an  elaborate  all  over  decoration,  we  have  only  simple 
lines,  which,  however,  were  placed  in  exactly  the  same  positions  as 
those  lines  which  on  the  older  specimens  had  served  to  divide  the 
surface  decoration  into  definite  panels  or  fields.  In  both  cases  a  pair 
of  lines,  beginning  at  the  base  of  the  blade  slit,  takes  a  downward, 
diverging  course,  passing  around  the  line  hole  and  terminating  on  both 
sides  at  a  small  barb  above  the  spur.  Similar  lines,  beginning  nearer 
the  tip,  emerge  just  above  the  other  pair  of  barbs,  which  are  thus 
accentuated  and  set  apart.  In  the  Old  Bering  Sea  heads,  the  areas 
between  these  dividing  lines  are  filled  in  with  more  or  less  elaborate 
designs ;  in  the  early  Punuk  heads  they  are  left  plain.  The  homology 
may  also  be  traced  in  another  feature,  namely  the  pairs  of  elevated 
circles  or  ellipses,  suggestive  of  "  eyes  ",  which  form  so  prominent 
a  part  of  the  Old  Bering  Sea  ornamentation.  In  the  early  Punuk 
heads  these  elevations  are  still  present,  although  less  prominent,  and 
they  occupy  the  same  position,  on  either  side  of  the  line  hole.  Al- 
though as  a  group  these  smaller  and  simpler  heads  are  later  than  the 
more  elaborate  forms,  they  appeared  at  a  rather  early  stage,  for  one 
of  them,  plate  24,  figure  20,  comes  from  a  depth  of  62  inches,  and 
two  others,  not  illustrated,  which  have  the  same  simple  ornamentation 
(although  they  are  larger  and  have  prominent  bifurcated  spurs)  were 
found  at  depths  of  48  and  62  inches. 
Plate  24,  figures  22  and  23  (cut  i,  30  in.  deep,  and  cut  9,  24  in. 
deep,  respectively)  represent  the  latest  of  the  several  forms  included 
in  type  III  x.  In  fact,  it  is  only  by  virtue  of  their  irregular  spurs 
that  they  are  included  in  this  group.  They  have  lost  the  smooth, 
flowing  contour  and  the  graceful,  curving  barbs  which  characterize 
such  intermediate  forms  as  those  shown  in  plate  24,  figures  19-21. 
Furthermore,  the  decoration  in  figure  23  is  that  of  phase  2  of  Punuk 
style  I  (lightly  incised  lines  with  small  spurs  attached — in  this  case 
with  the  spurs  connected)  a  style  which  becomes  quite  common  at 
a  somewhat  later  period. 
Open  socket  type  III  y. — In  general,  similar  to  type  III  x  except 
that  the  blade  slit  is  at  right  angles  to  the  line  hole.  The  spur  is  bi- 
furcated or  irregular,  and  the  barbs  along  the  sides  inconspicuous  or 
absent;  decorated  (Old  Bering  Sea  or  early  Punuk)  or  plain.  (PI.  23,
