   E.), 
  in 
  Molucca 
  Passage, 
  at 
  a 
  depth 
  of 
  417 
  fathoms, 
  on 
  a 
  bottom 
  of 
  

   gray 
  mud. 
  

  

  The 
  type 
  is 
  a 
  gravid 
  female. 
  The 
  eggs 
  are 
  large 
  and 
  are 
  contained 
  

   in 
  a 
  large 
  cigar-shaped 
  capsule. 
  

  

  Diplacanthopoma 
  squamiceps 
  Lloyd 
  is 
  very 
  similar 
  to 
  this 
  species. 
  

   It 
  differs 
  m 
  having 
  the 
  head 
  slightly 
  longer, 
  fewer 
  rays 
  in 
  the 
  pectoral, 
  

   and 
  (if 
  his 
  figure 
  is 
  correct) 
  ventrals 
  bifid, 
  scales 
  larger, 
  and 
  origin 
  of 
  

   anal 
  much 
  nearer 
  tip 
  of 
  caudal 
  than 
  tip 
  of 
  snout. 
  

  

  There 
  is

  example 
  in

  collection

  cm. 
  in 
  length 
  

   from 
  station 
  5515 
  (700 
  fathoms), 
  off 
  northern 
  Mindanao. 
  It 
  has 
  

   the 
  top 
  of 
  the 
  head 
  scaled, 
  as 
  in 
  squamiceps; 
  the 
  origin 
  of 
  the 
  anal 
  

   slightly 
  farther 
  back 
  than 
  in 
  the 
  type, 
  but 
  considerably 
  farther 
  

   forward 
  than 
  in 
  squamiceps.
