  equally 
  failed, 
  however, 
  in 
  detecting 
  the 
  relations 
  to 
  the 
  Cataphracti), 
  and 
  both 
  

   had 
  believed 
  they 
  could 
  perceive 
  a 
  resemblance 
  to 
  the 
  Gadoids 
  ;* 
  this 
  was 
  the 
  

   more 
  noteworthy, 
  as 
  the 
  later 
  observer 
  was 
  ignorant 
  of 
  the 
  labors 
  of 
  his 
  prede- 
  

   cessor 
  ; 
  and 
  it 
  was 
  also 
  with 
  interest 
  that 
  I 
  perceived 
  that 
  Dr. 
  Peters 
  had 
  like- 
  

   wise 
  been 
  struck 
  with 
  a 
  resemblance 
  of 
  the 
  same 
  form 
  to 
  the 
  trout 
  ; 
  naming 
  the 
  

   species 
  S. 
  salmoneus, 
  and 
  describing 
  it 
  as 
  trout-like 
  (Habitus 
  forellenahnlich). 
  

   Now 
  it 
  is 
  evident 
  from 
  a 
  study 
  of 
  the 
  anatomy, 
  that 
  these 
  several 
  forms 
  are 
  

   very 
  dissimilar 
  in 
  fundamental 
  characters 
  ; 
  and 
  most 
  of 
  them, 
  at 
  least, 
  quite 
  dis- 
  

   tantly 
  allied. 
  A 
  likeness 
  which 
  is 
  so 
  ambiguous 
  as 
  to 
  mislead 
  persons 
  equally 
  

   familiar 
  with 
  the 
  external 
  appearance 
  of 
  the 
  several 
  forms, 
  and 
  to 
  lead 
  to 
  such 
  

   dissimilar 
  results, 
  must 
  be 
  of 
  very 
  slight 
  importance. 
  At 
  any 
  rate, 
  the 
  affinities 
  

   of 
  the 
  form 
  in 
  question 
  {Anoplopoma 
  fimbria) 
  with 
  the 
  Cataphracti 
  — 
  and 
  more 
  

   especially 
  the 
  Ohiridse 
  — 
  are 
  evident 
  from 
  an 
  examination 
  of 
  the 
  external 
  and 
  in- 
  

   ternal 
  structure 
  ; 
  and 
  I 
  am 
  unable 
  to 
  appreciate 
  the 
  likeness 
  which 
  others 
  have 
  

   seen 
  to 
  the 
  cods, 
  the 
  mackerels, 
  or 
  the 
  trout.

  Mr. 
  Stearns 
  read 
  a 
  paper, 
  illustrated 
  by 
  drawings, 
  on 
  certain 
  

   Xylophagous, 
  or 
  wood-eating 
  animals,

  especially 
  to 
  the 
  

   Teredines

  the 
  moUusks,

   and 
  the

  among 
  the 
  terrestrial 
  Xylophaga. 
  

   Mr. 
  Stearns 
  called 
  the 
  attention 
  of 
  the 
  Academy 
  to 
  the 
  importance 
  

   of 
  the 
  cultivation 
  of 
  the 
  Eucalyptus 
  margiiiata, 
  as 
  the 
  wood 
  of 
  this 
  

   tree 
  is 
  exempt 
  from 
  the 
  attacks 
  of 
  all 
  the 
  above 
  species, 
  and 
  there- 
  

   fore 
  particularly 
  adapted 
  to 
  structures 
  of 
  wood 
  for 
  marine 
  positions.
