  REPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  noticeable 
  objects. 
  Cod 
  aud 
  haddock, 
  lioAvever, 
  may 
  browse 
  upon 
  

   alg'ic, 
  lij-droids, 
  etc., 
  for 
  the 
  sake 
  of 
  the 
  small 
  Crustacea, 
  mollusks, 
  aud 
  

   worms 
  attached 
  to 
  them. 
  

  

  Protective 
  mimicry 
  seems 
  of 
  little 
  avail 
  against 
  these 
  fishes, 
  as 
  the 
  

   ophinraus, 
  which 
  so 
  much 
  resemble 
  in 
  color 
  the 
  rocks, 
  sand, 
  aud 
  alg;e 
  

   amoug 
  which 
  they 
  live; 
  the 
  caprellas, 
  almost 
  iudistiuguishable 
  from 
  

   the 
  hydroids 
  and 
  algte; 
  aud 
  fishes 
  that 
  simulate 
  the 
  color 
  of 
  the 
  rocks 
  

   aud 
  plants 
  are 
  frequently 
  obtained 
  from 
  cod 
  stomachs. 
  Foreign 
  

   objects, 
  too, 
  are 
  occasionally 
  found 
  iu 
  the 
  stomachs 
  and 
  are 
  a 
  source 
  

   of 
  wonder 
  to 
  the 
  fisherman. 
  Eocks, 
  pieces 
  of 
  wood, 
  etc., 
  are 
  not 
  

   uncommon; 
  a 
  piece 
  of 
  rope 
  was 
  found 
  in 
  a 
  cod 
  stomach, 
  and 
  the 
  entire 
  

   globe 
  of 
  an 
  incandescent 
  electric 
  light 
  was 
  removed 
  from 
  the 
  stomach 
  

   of 
  a 
  pollock. 
  

  

  The 
  pollock 
  examined 
  had 
  been 
  feeding 
  almost 
  exclusively 
  upou 
  a 
  

   shrimp-like 
  animal 
  ( 
  Thysanopoda) 
  and 
  prawns. 
  The 
  thysanopodas 
  were 
  

   very 
  abundant 
  at 
  Eastport 
  during 
  the 
  season 
  mentioned 
  and 
  large 
  

   schools 
  of 
  i>ollock 
  of 
  nearly 
  all 
  sizes 
  were 
  very 
  numerous, 
  feeding 
  upon 
  

   them. 
  If 
  at 
  auy 
  time 
  the 
  crustacean 
  disajJi^eared 
  from 
  a 
  place 
  the 
  

   large 
  pollock 
  disappeared 
  also. 
  The 
  small 
  fish 
  remained 
  in 
  large 
  num- 
  

   bers 
  about 
  the 
  wharves. 
  

  

  The 
  contents 
  of 
  the 
  hake 
  stomachs 
  examined 
  consisted 
  almost 
  uni- 
  

   formly 
  of 
  thysanopodas 
  and 
  prawns 
  {Pandalus). 
  

  

  The 
  amphipods 
  were 
  identified 
  mainly 
  by 
  the 
  aid 
  of 
  Stimpson's 
  

   "Invertebrates 
  of 
  Grand 
  Manau," 
  the 
  nomenclature 
  iu 
  that 
  paper 
  

   being 
  adopted, 
  with 
  the 
  exception 
  of 
  a 
  few 
  species 
  identified 
  by 
  the 
  

   means 
  of 
  Yerriirs 
  "Invertebrates 
  of 
  Vineyard 
  Sound." 
  Doubtless 
  

   some 
  of 
  these 
  names 
  have 
  become 
  synonyms, 
  but 
  it 
  is 
  thought 
  that 
  

   anyone 
  desiring 
  to 
  know 
  the 
  recent 
  names 
  of 
  the 
  amphipods 
  enumer- 
  

   ated 
  in 
  the 
  list 
  will 
  be 
  able 
  to 
  find 
  them. 
  

  

  Thanks 
  are 
  tendered 
  Mr. 
  James 
  E. 
  Benedict, 
  assistant 
  curator 
  of 
  

   marine 
  iuvertebrates

  States

  Museum,

  and

  others 
  of 
  the 
  mollusks.
