Il6  SMITHSONIAN    MISCELLANEOUS    COLLECTIONS  VOL.    96 
Open  Socket  Harpoon  Heads 
Open  socket  type  II  (a)  x. — Two  lashing  slots  or  one  slot  and  an 
opposite  groove ;  bifurcated,  asymmetrical  spur ;  round  line  hole ;  two 
side  blades,  parallel  with  line  hole  ;  long  and  slender,  squarish  in  cross- 
section  ;  usually  made  of  bone.    (PI.  28,  fig.  i.) 
Two  examples,  both  of  bone:  cut  i,  depth  12  inches;  cut  19,  depth 
24  inches  (pi.  28,  fig.  i). 
This  is  a  derivative  of  the  older  type  II  x,  from  which  it  diflfers  in 
having  two  instead  of  three  prongs  on  the  spur;  it  is  also  long  and 
slender  in  shape,  whereas  type  II  x  was  shorter  and  more  or  less 
rounded  in  cross-section.  A  further  difiference  is  that  both  specimens 
of  the  present  type  are  of  bone,  and  that  one  of  them  (pi.  28,  fig.  i) 
has  a  single  lashing  slot,  with  an  opposite  groove  instead  of  two  slots. 
Open  socket  type  II  (a)  y. — Same  as  above  but  with  the  side  blades 
at  right  angles  to  the  line  hole  ;  flattened  oval  in  cross  section.  (PI.  28, 
fig,  2.) 
Three  examples,  all  of  bone:  cut  i,  depth  12  inches  (pi.  28,  fig.  2)  ; 
cut  19,  depth  17  inches;  cut  20,  depth  22  inches. 
This  form  is  derived  from  type  II  y,  differing  from  it  in  having 
two  instead  of  three  prongs  on  the  spur,  and  in  sometimes  having  one 
lashing  slot  with  an  opposite  groove  instead  of  two  slots.  The  re- 
maining fragmentary  side  blade  of  plate  28,  figure  2,  is  made  of  a 
piece  of  shell. 
Open  socket  types  II  (b)  x,  II  (b)  y,  II  (c)  x,  and  //  (r)  3;  are 
variants  of  the  type  II  group  which  were  not  found  at  Miyowagh. 
Examples  from  the  next  site,  levoghiyoq,  will  be  described  later. 
Open  socket  type  II  (d). — Two  lashing  slots;  a  bifurcated  asym- 
metrical spur ;  round  line  hole ;  neither  end  nor  side  blades ;  long  and 
slender;  made  of  bone.    (PI.  28,  fig.  3.) 
This  type,  which  apparently  was  little  used  at  Gambell,  is  based  on 
the  single  specimen  shown  in  plate  28,  figure  3,  from  the  north- 
western section  of  the  midden,  cut  17,  depth  20  inches.  It  is  a  late 
variant  of  the  type  II  head,  and  is  of  particular  interest  as  repre- 
senting the  first  appearance  at  Gambell  of  a  harpoon  head  which  has 
neither  blade  nor  barbs. 
Open  socket  type  II  (e). — One  lashing  slot  and  an  opposite  groove ; 
a  bifurcated,  asymmetrical  spur;  triangular  to  rectangular  line  hole; 
two  small  lateral  barbs,  at  right  angles  to  line  hole ;  no  blades ;  long 
and  slender.   (PI.  28,  fig.  4.) 
Another  uncommon  type,  represented  by  the  single  specimen,  of 
ivory,  shown  in  plate  28,  figure  4,  from  cut  i,  in  the  northwestern 
section  of  the  midden  at  a  depth  of  24  inches.
