spur  extends  straight  down  and  is  fairly  wide  across  the  tip ;  in  the 
later  levoghiyoq  heads  the  spur  flares  outward  and  becomes  narrow 
and  arched,  the  sides  having  been  cut  down  at  an  acute  angle  from 
the  median  ridge,  which  is  thereby  made  to  stand  out  more  prominently 
(pi,  63,  figs.  10-14).  This  arched  form  of  spur,  in  the  most  typical 
examples,  is  still  further  accentuated  by  having  the  tip  cut  off  obliquely, 
giving  it  the  appearance  of  curving  inward,  as  in  some  cases  (e.  g., 
fig.  12)  it  actually  does.  About  90  percent  of  the  levoghiyoq  heads 
have  this  arched  form  of  spur  in  some  degree,  and,  just  as  in  the 
case  of  ornamentation,  those  which  do  not  have  it  come  for  the  most 
part  from  the  lower  levels  of  the  midden. 
As  a  rule  the  line  holes  on  the  levoghiyoq  heads  are  somewhat  larger 
than  those  from  Miyowagh  and  the  shallow  groove  beneath  the  line 
hole  is  usually  lacking. 
In  addition  to  such  specific  dififerences  in  individual  features,  many 
of  the  later  heads  from  levoghiyoq  are  heavier  and  thicker,  particularly 
around  the  lower  end  (pi.  70,  figs.  10,  11,  and  14). 
Plate  70,  figure  9,  has  part  of  the  baleen  lashing  remaining  in  one 
of  the  slots,  and  the  same  is  true  of  one  other  specimen  from  cut  5. 
Plate  70,  figure  16,  from  cut  9,  depth  12  inches,  possesses  several 
features  that  set  it  apart  from  type  III  (a)  x.  It  has  a  bifurcated  spur, 
a  groove  opposite  the  single  lashing  slot,  and  a  deeply  cut  Y-figure 
above  the  line  hole  on  both  sides ;  furthermore,  it  is  of  bone,  whereas 
all  but  one  of  the  other  type  III  (a)  x  heads  are  of  ivory. 
Open  socket  type  III  (a)  y. — This  type,  with  the  blade  slit  at  right 
angles  to  the  line  hole,  is  not  represented  at  levoghiyoq.  As  noted 
previously,  the  distribution  of  this  type  at  Miyowagh  indicated  that 
it  was  somewhat  earlier  than  type  III  (a)  x,  in  which  the  blade  slit 
and  line  hole  were  parallel.  The  present  evidence  is  confirmatory  in 
this  respect,  the  type  apparently  having  been  discontinued  before 
levoghiyoq  was  established. 
Open  socket  type  IV. — Two  lashing  slots;  single,  lateral  spur; 
round  or  triangular  line  hole ;  two  prominent  lateral  barbs,  at  right 
angles  to  line  hole ;  no  end  blade ;  undecorated.  Dififers  from  type 
II  (e)  in  the  lashing  arrangement  and  size  of  the  barbs.  (PI.  70, 
figs.  4,  5.) 
There  are  nine  examples  of  this  type,  distributed  as  follows :  Cut 
I,  depth  22  inches  (pi.  70,  fig.  4)  ;  31  inches.  Cut  5,  24  inches  (2, 
one  bone,  one  ivory — pi.  70,  fig.  5).  Cut  6,  9  inches;  36  inches.  Cut 
8,  25  inches.  Cut  9,  31  inches;  34  inches  (bone).  In  form  these  har- 
poon heads  are  identical  with  Mathiassen's  Thule  type  2.  However, 
they  do  not  have  the  Y-shaped  figure  above  the  line  hole  as  do  the
