  sp. 
  nov. 
  

  

  Rays 
  five, 
  rather 
  short 
  and 
  stout, 
  smaller, 
  subacute. 
  The 
  

   skeleton 
  plates 
  are 
  larger, 
  firmer, 
  and 
  more 
  rigid 
  than 
  in 
  the 
  

   allied 
  species. 
  Radii 
  10 
  mm 
  and 
  35 
  mm 
  . 
  Dorsal 
  surface 
  rather 
  

   sparsely 
  covered 
  with 
  short, 
  stout, 
  blunt, 
  isolated 
  spines, 
  which 
  

   do 
  not 
  form 
  regular 
  rows 
  ; 
  those 
  along 
  the 
  median 
  area 
  of 
  the 
  

   rays 
  are 
  a 
  little 
  longer 
  and 
  often 
  stand 
  in 
  an 
  irregular 
  double 
  

   row 
  ; 
  a 
  distinct, 
  regular 
  supero-marginal 
  row 
  of 
  slightly 
  longer, 
  

   but 
  similar, 
  spines 
  ; 
  two 
  infero-marginal 
  rows 
  of 
  still 
  longer 
  

   and 
  more 
  acute 
  spines, 
  separated 
  by 
  a 
  line 
  of 
  papulae, 
  placed 
  

   singly 
  to 
  near 
  the 
  end 
  of 
  the 
  rays, 
  and 
  sometimes 
  with 
  a 
  short 
  

   row 
  of 
  intervening 
  spines 
  distally. 
  Adambulacral 
  spines 
  

   small, 
  slender, 
  not 
  very 
  long, 
  scarcely 
  tapered, 
  arranged 
  either 
  

   one 
  or 
  two 
  to 
  a 
  plate, 
  sometimes 
  alternately, 
  but 
  generally 
  the 
  

   solitary 
  ones 
  are 
  most 
  numerous. 
  Papulae 
  stand 
  singly 
  or 
  in 
  

   small 
  clusters. 
  Cruciform 
  pedicellarise 
  minute, 
  forming 
  a 
  close 
  

   wreath 
  around 
  all 
  the 
  dorsal 
  and 
  lateral 
  spines, 
  those 
  of 
  the 
  

   ventral 
  spines 
  interrupted 
  below. 
  Rectiform 
  pedicellariae 
  of 
  

   rather 
  large 
  size, 
  narrow 
  ovate 
  or 
  acute 
  lanceolate 
  in 
  form, 
  are 
  

   scattered 
  between 
  the 
  dorsal 
  spines 
  ; 
  others 
  of 
  large 
  size 
  and 
  

   less 
  acute 
  occur 
  between 
  the. 
  ventral 
  and 
  adambulacral 
  spines; 
  

   smaller 
  ones 
  lie 
  within 
  the 
  furrows.

  George's 
  Bank 
  and 
  off 
  Cape 
  Cod. 
  

  

  This 
  species 
  should, 
  perhaps, 
  be 
  referred 
  to 
  Leptasterias. 
  

   The 
  character 
  of 
  its 
  ova 
  is 
  not
