NO.    I  ARCHKOLOGY    OF    ST.    LAWRENCE    ISLAND — COLLINS  II7 
Open  socket  type  II  (/)  x. — Two  lashing  slots ;  bifurcated,  sym- 
nietrical  (median)  spur;  triangular  line  hole;  end  blade,  parallel  with 
line  hole;  ornamental,  vestigial  slots  for  side  blades,  at  right  angles 
to  line  hole.    (PI.  28,  fig.  5.) 
This  type  is  based  on  the  single  specimen,  of  bone,  shown  on 
plate  28,  figure  5,  from  cut  20,  depth  12  inches.  The  bifurcated,  sym- 
metrical spur,  placed  medially  below  the  socket,  the  triangular  line 
hole,  and  the  two  vestigial  sockets  for  side  blades  are  features  that 
show  relationship  to  type  II  (b)  y ;  a  type  not  found  at  Miyowagh  but 
represented  by  two  specimens  from  the  Punuk  site,  levoghiyoq.  The 
slit  for  an  end  blade  relates  it  to  the  following  type,  type  II  (g)  x. 
Decoration  consists  of  a  pair  of  straight  lines  diverging  downward ; 
the  shallow  grooves  along  the  edges  at  the  constricted  center,  although 
now  only  ornamental,  undoubtedly  represent  vestigial  sockets  for  side 
blades. 
Open  socket  type  II  (g)  x. — Two  lashing  slots  or  one  slot  with  an 
opposite  groove;  a  bifurcated,  asymmetrical  spur;  round  line  hole; 
end  blade,  parallel  with  line  hole  ;  made  of  bone ;  simple  line  decoration. 
(PI.  28,  figs.  6,  7.) 
This  is  one  of  the  instances  where  a  determination  of  relationship 
based  strictly  on  definition  would  be  misleading.  Thus,  plate  28, 
figure  7,  possesses  the  general  features  that  would  place  it  in  type 
III  X :  two  lashing  slots,  a  bifurcated,  asymmetrical  spur,  an  end  blade 
parallel  with  a  round  line  hole.  But  both  this  specimen  and  plate  28, 
figure  6,  lack  the  graceful,  flowing  contour  and  the  small  barbs  of  type 
III  X.  Furthermore,  the  nature  of  the  bifurcated  spurs,  the  decora- 
tion of  straight  lines,  and  the  fact  that  these  heads  are  made  of  bone 
rather  than  ivory  show  that  their  true  relationship  is  with  the  type  II 
group. 
Plate  28,  figure  6,  from  cut  6,  depth  20  inches,  is  rather  crudely 
made :  it  has  one  lashing  slot  and  an  opposite  groove.  Plate  28,  figure 
7,  from  cut  2,  depth  28  inches,  has  two  lashing  slots ;  in  addition  to 
the  simple  line  decoration,  it  has  a  deep  V-shaped  depression  above 
the  line  hole. 
The  harpoon  heads  above  described  [types  II  (a)  x  and  y ;  II  (d)  ; 
II  (e)  ;  II  (f)  x;  II  (g)  x]  are  collectively  the  most  recent  of  all 
the  Miyowagh  forms.  They  all  come  from  the  northwestern  section 
of  the  midden,  one  of  them  (pi.  28,  fig.  7)  from  a  depth  of  28  inches, 
the  nine  others  from  even  shallower  depths.  They  were  relatively 
unimportant  at  Miyowagh,  being  overshadowed  by  the  more  domi- 
nant forms  of  type  III  (a)  x  and  y.  One  of  them — type  II  (a)  x — is 
a  degenerate  form  of  type  II  x  (pi.  24,  figs.  5-8),  a  type  which  goes
