  even 
  greater 
  than 
  that 
  observed 
  by 
  Maas 
  (1905) 
  and 
  by 
  me 
  (1909a). 
  

   As 
  pointed 
  out 
  elsewhere, 
  this 
  fact 
  is 
  probably 
  of 
  phylogenetic 
  impor- 
  

   tance, 
  showing 
  that 
  the 
  pockets 
  are 
  primarily 
  radial, 
  as 
  in 
  Cunina. 
  

  

  This 
  specimen 
  is 
  a 
  female 
  with 
  large 
  eggs, 
  and 
  it 
  shows 
  that 
  the 
  

   reason 
  that 
  the 
  eggs 
  in 
  the 
  large 
  eastern 
  Pacific 
  example 
  showed 
  

   white 
  (1909a, 
  pi. 
  9, 
  fig. 
  4) 
  was 
  that 
  the 
  overlying 
  tissue 
  was 
  torn, 
  

   or 
  at 
  least 
  that 
  the 
  pigment 
  was 
  destroyed. 
  In 
  the 
  present 
  case 
  they 
  

   are 
  made 
  visible 
  only 
  by 
  the 
  swellings 
  which 
  they 
  cause, 
  exactly 
  as 
  in 
  

   Solmissus 
  marshalli 
  (1909a, 
  pi. 
  21, 
  fig. 
  7). 
  

  

  Color. 
  — 
  In 
  the 
  best 
  preserved 
  specimens 
  the 
  central 
  stomach 
  and 
  

   gastric 
  pouches 
  are 
  very 
  dense, 
  opaque, 
  chocolate-brown, 
  with 
  more 
  

   or 
  less 
  pronounced 
  reddish 
  tinge, 
  \viih 
  the 
  marginal 
  region 
  of 
  the 
  

   subumbrella 
  pale 
  reddish; 
  i. 
  e., 
  of 
  about 
  the 
  same 
  color 
  as 
  the 
  speci- 
  

   mens 
  of 
  the 
  species 
  previously 
  recorded. 
  

  

  In 
  the 
  two 
  specimens 
  named 
  by 
  Vanhoffen 
  var. 
  munda, 
  the 
  marginal 
  

   region 
  was 
  white; 
  and 
  this 
  was 
  their 
  sole 
  distinguishing 
  character. 
  

   But 
  there 
  is 
  no 
  sharp 
  line 
  between 
  them 
  and 
  specimens 
  w4th 
  pale 
  red- 
  

   dish 
  margin 
  and 
  his 
  own 
  ohscura 
  in 
  which 
  the 
  marginal 
  region 
  was 
  

   densely 
  pigmented.
