  FISHERIES.

  37. 
  Benthcecetes 
  Barlletti. 
  578 
  to 
  1,081. 
  

  

  Eyes 
  about 
  as 
  large 
  and 
  of 
  the 
  same 
  color 
  as 
  in 
  the 
  last 
  species 
  ; 
  papilla 
  very 
  

   conspicuous, 
  but 
  low 
  and 
  obtuse; 
  a 
  mass 
  of 
  black 
  pigment 
  near 
  the 
  mid- 
  

   dle 
  of 
  the 
  stalk, 
  more 
  distinctly 
  visible 
  from 
  the 
  ventral 
  than 
  from 
  the 
  

   dorsal 
  side. 
  

  

  38. 
  Benthonectcs 
  filipes. 
  693 
  to 
  1,043. 
  

  

  Eyes 
  very 
  large, 
  swollen, 
  reniform, 
  extending 
  far 
  along 
  the 
  mesial 
  side 
  of 
  the 
  

   stalk; 
  pigment 
  dark 
  brown, 
  abundant; 
  papilla 
  prominent. 
  

  

  39. 
  Benihcsicymus? 
  carinatus. 
  1,020. 
  

  

  Eyes 
  apparently 
  very 
  nearly 
  as 
  in 
  37, 
  but 
  imperfect 
  in 
  the 
  single 
  known 
  spec- 
  

   imen. 
  

  

  40. 
  Beuthesicymus? 
  moratus. 
  1,537 
  to 
  1,710. 
  

  

  Eyes 
  nearly 
  as 
  in 
  38, 
  except 
  that 
  the 
  pigment 
  is 
  apparently 
  white 
  or 
  very 
  

   light 
  in 
  color. 
  

  

  SEEGESTID^I. 
  

  

  41. 
  Seigestes 
  arcticus. 
  221 
  to 
  2,516. 
  

  

  Eyes 
  highly 
  developed, 
  large 
  ; 
  pigment 
  black; 
  apparently 
  neither 
  papilla 
  

   nor 
  dorsal 
  area. 
  

  

  42. 
  Serge&tes 
  robustus. 
  372 
  to 
  2,574. 
  

  

  Eyes 
  similar 
  to 
  those 
  of 
  the 
  last 
  species, 
  but 
  even 
  larger, 
  the 
  cornea 
  being 
  

   nearly 
  hemispherical. 
  

  

  43. 
  Sergestes 
  mollis. 
  373 
  to 
  2,94'J. 
  

  

  Eves 
  small, 
  little 
  larger 
  than 
  the 
  diameter 
  of 
  the 
  stalks; 
  pigment 
  black, 
  

   abundant. 
  

  

  The 
  following 
  species, 
  though 
  not 
  yet 
  recorded 
  from 
  below 
  1,000 
  

   fathoms, 
  might 
  properly 
  enough 
  be 
  added 
  to 
  this 
  list, 
  as 
  they 
  undoubt- 
  

   edly 
  all 
  extend 
  below 
  the 
  1,000-fathom 
  line 
  : 
  

  

  44. 
  Sclcrocranyon 
  Agassizii. 
  390 
  to 
  959. 
  

  

  Eyes 
  small, 
  no 
  larger 
  than 
  the 
  stalks, 
  which 
  are 
  very 
  little 
  dilated 
  distally; 
  

   pigment 
  black 
  or 
  nearly 
  so. 
  

  

  45. 
  Sabinea 
  princepx. 
  353 
  to 
  888. 
  

  

  Eyes 
  highly 
  developed, 
  large; 
  pigment 
  black. 
  

  

  46. 
  Nematocarcirms 
  cursor. 
  384 
  to 
  838. 
  

  

  Similar 
  to 
  18, 
  but 
  somewhat 
  larger, 
  and 
  with 
  the 
  papilla 
  very 
  distinct, 
  though 
  

   small. 
  

  

  47. 
  Acanthephyra 
  eximca. 
  938. 
  

  

  Eyes 
  very 
  nearly 
  as 
  in 
  19. 
  

  

  48. 
  Ephyrina 
  Bencdicti. 
  959. 
  

  

  Eyes 
  rather 
  small, 
  apparently 
  not 
  capable 
  of 
  great 
  mobility, 
  very 
  little 
  larger 
  

   than 
  the 
  diameter 
  of 
  the 
  stalks 
  ; 
  pigment 
  black 
  ; 
  papilla 
  distinct 
  ; 
  dorsal 
  

   area 
  absent. 
  

  

  The 
  first 
  question 
  which 
  arises 
  in 
  discussing 
  the 
  bathymetrical 
  hab- 
  

   itats 
  of 
  the 
  species 
  in 
  this 
  list 
  is, 
  Which 
  of 
  them 
  actually 
  inhabited 
  the 
  

   bottom, 
  or 
  the 
  region 
  near 
  the 
  bottom, 
  at 
  the 
  depths 
  from 
  which 
  they 
  

   are 
  recorded, 
  and 
  what 
  depths 
  do 
  the 
  remaining 
  species 
  inhabit? 
  That 
  

   none 
  of 
  them 
  are 
  truly 
  pelagic 
  surface 
  species 
  may, 
  I 
  think, 
  be 
  taken 
  

   for 
  granted, 
  for, 
  with 
  the 
  single 
  exception 
  of 
  Acanthephyra 
  Agassizii, 
  

   none 
  of 
  the 
  free-swimming 
  species 
  have 
  been 
  taken 
  anywhere 
  near 
  the
