Bering  Sea  decoration  which  must  somewhat  arbitrarily  be  inckided 
in  the  group  because  they  possess  single  spurs  and  the  other  features 
characteristic  of  the  type.  One  of  these  is  from  the  Hillside  site 
(pi.  23,  fig.  10),  the  other  two  from  the  southeastern  section  of 
Miyowagh,  cut  25,  18  inches  deep,  and  cut  9  a,  52  inches  deep.  The 
last  mentioned  specimen  is  so  badly  weathered  that  most  of  the  super- 
ficial features  are  obliterated ;  the  other  two,  however,  both  have  small 
ornamental  barbs  along  the  edges,  such  as  are  characteristic  of  type 
III  X.  These  barbs,  together  with  the  ornamentation,  indicate  rela- 
tionship to  type  III  X,  even  though  for  the  purpose  of  classification 
it  is  necessary,  because  of  the  single  spur,  to  include  them  in  type  III 
(a)x. 
Type  III  (a)  X  is  an  important  one  at  Miyowagh,  being  represented 
by  38  specimens  in  addition  to  the  2  just  mentioned.  Of  these  38, 
only  one  is  undecorated,  the  others  all  bear  a  Punuk  ornamentation. 
Three  are  from  the  older,  southeastern  section,  as  follows :  cut  7, 
depth  20  inches;  cut  9,  12  inches  (pi.  28,  fig.  11)  ;  36  inches. 
Thirty-five  are  from  the  later,  northwestern  section:  Cut  i,  12 
inches;  24  inches  (2)  (pi.  28,  fig.  13)  ;  48  inches.  Cut  2,  12  inches; 
24  inches  (2)  (pi.  28,  fig.  8).  Cut  3,  24  inches.  Cut  4,  15  inches; 
20  inches;  25  inches  (pi.  28,  fig.  14)  ;  31  inches  (pi.  28,  fig.  12)  ;  39 
inches.  Cut  17,  26  inches;  27  inches  (2)  ;  34  inches.  Cut  19,  5  inches 
(3)  ;  12  inches  (3)  (pi.  28,  fig.  10)  ;  17  inches  (6)  (pi.  28,  fig.  9)  ; 
24  inches ;  48  inches.   Cut  20,  12  inches;  22  inches;  26  inches  (2). 
In  describing  the  harpoon  heads  of  the  Old  Bering  Sea  period,  it 
was  pointed  out  (pp.  104-106)  that  open  socket  type  III  x  was  a 
variable  form  that  had  undergone  considerable  modification  during 
the  period  in  which  Miyowagh  was  occupied.  The  older  specimens 
were  mostly  large,  elaborately  ornamented,  and  possessed  prominent, 
divided  spurs ;  the  later  specimens  were  of  smaller  size,  were  decorated 
in  the  simplified  style  of  the  early  Punuk,  and  had  spurs  which, 
although  considerably  reduced,  were  still  to  be  classed  as  "  irregular." 
The  type  III  (a)  x  heads  represent  a  continuation  of  this  process 
of  simplification.  In  general  shape  and  style  of  ornamentation  they 
are  similar  to  the  latest  of  the  type  III  x  heads,  such  as  plate  24, 
figures  22  and  23 ;  the  principal  difiference  being  that  the  spur  has 
lost  all  trace  of  its  former  irregularity  and  is  now  perfectly  straight 
and  plain.  Furthermore,  while  the  earlier  forms  of  the  type  III  x 
heads  were  oval  in  cross-section,  with  a  more  or  less  rounded  contour, 
a  few  of  the  later  examples,  like  plate  24,  figures  22  and  23,  were 
somewhat  squarer  in  outline,  with  plane  median  surfaces  and  beveled 
edges.    In  the  type  III  (a)  x  heads  the  same  tendency  is  continued:
